UK Consumers Priorities for Sustainable Food Purchases

Although interest in ‘sustainable food’ has grown substantially in recent years, an official definition for sustainability has yet to be agreed upon. ‘Sustain: the alliance for better food and farming’ provide guidance to consumers wishing to make more sustainable food purchases, in the form of seven guiding principles. Using these principles, this study seeks to assess UK consumer’s priorities towards sustainable food. A detailed structured questionnaire explored shopping habits, attitudes to sustainable food components (organic, fair-trade, local food and animal welfare), stated purchasing behaviour and demographic information. Questionnaires were sent to 2,500 randomly selected Nottinghamshire (UK) residents. A response rate of 35.6% was achieved. The data reveals that consumers prioritise packaging, how food is produced and animal welfare when considering sustainable food components. Stated purchasing behaviour demonstrates that ‘free range’ and ‘local’ products are more likely to take precedence over other sustainability aspects. Future research will seek to compare and contrast stated and actual preferences by comparing the population survey results to actual purchasing behaviour from supermarket data.Consumer, sustainable food, purchasing behaviour, free range, local, animal welfare, Food Consumption/Nutrition/Food Safety,

Reliability of equivalent sphere model in blood-forming organ dose estimation

The radiation dose equivalents to blood-forming organs (BFO's) of the astronauts at the Martian surface due to major solar flare events are calculated using the detailed body geometry of Langley and Billings. The solar flare spectra of February 1956, November 1960, and August 1972 events are employed instead of the idealized Webber form. The detailed geometry results are compared with those based on the 5-cm sphere model which was used often in the past to approximate BFO dose or dose equivalent. Larger discrepancies are found for the later two events possibly due to the lower numbers of highly penetrating protons. It is concluded that the 5-cm sphere model is not suitable for quantitative use in connection with future NASA deep-space, long-duration mission shield design studies

Aging Group Consciousness and Cohesion: Some Empirical Considerations

This is the third and final evaluation of a recreation program sponsored by the Omaha Parks, Recreation and Public Property Department in public housing facilities for the elderly. John A. Ballweg (1967) conducted the first evaluation and the second was conducted by Judy Kessler and George W. Barger with the assistance of Nancy C. Wilson (1968). Major questions to be considered here are: 1. What is the extent of participation in the recreation program among the residents? 2. Have patterns of social relationships changed since the subjects moved into public housing? 3. What types of friendship groups have developed within the apartment buildings? 4. How cohesive are the friendship groups in the buildings, and is this cohesiveness related to the degree of conformity to information group norms relative to the extent of participation in the recreation program? 5. Are these senior citizens aging group conscious (Rose, 1965a)? What attitudes and behaviors distinguish those persons showing aging group consciousness from those who do not

Green's function methods in heavy ion shielding

An analytic solution to the heavy ion transport in terms of Green's function is used to generate a highly efficient computer code for space applications. The efficiency of the computer code is accomplished by a nonperturbative technique extending Green's function over the solution domain. The computer code can also be applied to accelerator boundary conditions to allow code validation in laboratory experiments

Effects of fragmentation parameter variations on estimates of galactic cosmic ray exposure: Dose sensitivity studies for aluminum shields

Initial studies of the sensitivities of estimates of particle fluence, absorbed dose, and dose equivalent to fragmentation parameter variations are undertaken by using the LaRC galactic cosmic ray transport code (HZETRN). The new results, presented as a function of aluminum shield thickness, include upper and lower bounds on dose/dose equivalent corresponding to the physically realistic extremes of the fragmentation process and the percentage of variation of the dose/dose equivalent as a function of fragmentation parameter variation
