ABSTRACT   Food mishandling is thought to be more acute among young adults; yet little is known about why they may engage in risky food handling behaviors. The purpose of this study was to create valid, reliable instruments for assessing key food safety psychosocial measures. Development of the measures began by examining published studies and behavior change theories to identify the psychosocial factors associated with personal health choices and 3 psychosocial factors were identified: beliefs, locus of control, and self-efficacy. Development of items for the belief questionnaire began by identifying the belief constructs that could provide insight into how food safety behavior change programs should be framed to evoke improved behaviors and drafting items. The locus of control questionnaire was modeled after the Health Locus of Control Questionnaire. Self-efficacy questionnaire development included defining self-efficacy, identifying environmental contexts affecting self-efficacy, and constructing an item pool. The questionnaires were pretested with young adults (n= 180) and refined. A pilot test (n= 77) was conducted to further refine the beliefs and self-efficacy questionnaires. Finally, young adults (n= 4343, mean age 19.9 ± 1.7 SD y) from 21 universities and colleges across the country completed the questionnaires. Analysis of their responses revealed that these questionnaires met or exceeded standards indicative of high-quality psychosocial food safety measures. These questionnaires should be useful in generating baseline data from adults as well as establishing the value of these measures in assessing the effectiveness of food safety interventions.

    ABSTRACT: The authors determined the food safety knowledge, attitudes, and behaviors of undergraduates (n = 1122) on an urban college campus using a previously piloted survey tool. Data obtained found that while students reported high levels of confidence in their ability to engage in safe food handling practices, their knowledge and self-reported behaviors indicated that they were not actually engaging in safe food handling practices. Students were particularly lacking knowledge with respect to proper temperatures for cooking, reheating, and refrigerating foods. The data were further analyzed to determine differences in food safety knowledge and practices between populations of different demographics within the students. Differences were found between male and female students, Caucasian and Asian students, and students who had worked in food service compared with those who had not. A final aspect of this study evaluated the effectiveness of a social marketing campaign to increase awareness of safe food handling practices among college undergraduates. A cross-sectional, quasi-experimental, pre- and posttest design was used. Following the baseline knowledge survey described previously, a social marketing campaign developed for young adults was implemented on the campus over a 4-wk period that included promotional events and incentives. Postcampaign survey results indicated increases in food safety knowledge, attitudes, and behaviors, particularly with respect to appropriate temperatures for cooking and refrigeration and found that e-mails and posters may be effective ways to communicate food safety messages to this population.

    ABSTRACT: form only given. The new conjugated polymer poly(tetraphenylquinodimethans) (PTPhQ) with degenerate ground state has been obtained in linear (presumably 10) and not-work (presumably 2D) modification by the method of oxidative condensation of diphenylmethane or its chlorine derivatives in the presence of Lewis acids. The PTPhQ has all properties characteristic for conjugated polymers. The neutral form of 1D PTPhQ is soluble and films can be obtained from solutions. Transformation of PTPhQ from neutral to doped form is accompanied by changes in optical spectra and increasing of its conductivity. The doping of PTPhQ by Lewis acids is accompanied by appearance and growth of ESR signal. For example when the 1D PTPhQ is doped by SbCl/sub 5/ the ESR signal with g - value about 2, /spl Delta/ H = 7,2/sup 5/ - 7,9 Gauss and spin concentration more than 10/sup +22/ spins/mo] is observed. The very wide line ( > 5000 Gauss) without fine structure in spectra ESR is also observed.

    ABSTRACT: Purpose – This study was conducted with the aim of determining the food purchasing behaviour of consumers from supermarkets. Design/methodology/approach – A total of 430 consumers, 194 males and 236 females, with an average age of 29.96 ±10.99 were included in this study, and was conducted to find out the criteria which consumers took into account while purchasing food. Findings – A significant relationship was determined between the scores the consumers received from nutrition, the reliability and all of the shopping criteria, and their level of education (p < 0.05) between the percentage of income spared for nutrition (p < 0.01) and between the cost (p < 0.05) and the total scores received from all of the shopping criteria (p < 0.01). It was also determined that women paid more attention to the nutrition and reliability criteria than men did (p < 0.05). Research limitations/implications – The research is restricted in so far as it only considers consumers in the big city and as it is an exploratory study the research is limited in so far as the number of participants is only 430. Further research needs to include other big and small cities. Practical implications – The study has concluded that consumers need effective and versatile education in the subjects of label reading and buying the right kind of food for their budgets. It is revealed that consumer education is essential in the process from cradle to grave in creating the awareness of consumers to buy food. Originality/value – The paper is useful to both practitioners and academics in the fields of relationship consumer and marketing. Informing and training consumers will help increase the awareness of consumers and make them behave more rationally in their shopping. It will lead the studies to be carried out in the future to activate the control of the consumers on their shopping, instead of losing the control of consumers.
