A Citizen's Handbook for Evaluating Community Impacts: an Experiment in Community Education
Four nonmetropolitan communities were selected for an experimental community education program designed to train local citizens in the general procedures of economic impact research. It is argued that citizen participation is enhanced by a fuller understanding of the technical content of the planning problem at hand and that this understanding is best developed through involvement in a citizen research process prior to policy formulation. The experiment was only partially successful. A handbook was developed that is easily used by lay persons to make impact estimates, but a broad base of citizen involvement in research could not be developed. Community interest was strongest in places anticipating impacts in the near term. Retirees, citizens who could receive specific immediate benefits, and local planners and managers emerged as the best community analysts.
Estimating the Economic Base Multiplier: A Test of Alternative Procedures
Four different strategies for estimating economic base multipliers are evaluated for twenty small towns in Arizona. Three estimating techniques are compared with a comprehensive survey of the economies of the towns, and the minimum requirements method is found to be superior to the sample survey and location quotient approaches.
The Prevalence of Dietary Supplement Use among College Students: A Nationwide Survey in Japan
To clarify the prevalence of dietary supplement use among college students, we conducted Internet-based nationwide questionnaire surveys with 157,595 Japanese college students aged between 18 to 24 years old who were registrants of Macromill Inc. (Tokyo, Japan). Among the 9066 respondents (response rate 5.8%), 16.8% were currently using dietary supplements. The prevalence of dietary supplement use did not differ significantly between males (17.1%) and females (16.7%). However, it increased according to their grade (13.1% to 20.5%), and it was higher in medical and pharmaceutical college students (22.0%) compared to others (16.7%). The main purpose of dietary supplement use was for the health benefits in both males and females. Other reasons were to build muscle in males, and as a beauty supplement and for weight loss in females. According to the purpose of dietary supplement use, the most commonly-used dietary supplements were vitamin/mineral supplements in both males and females, then protein and weight loss supplements in males and females, respectively. Although most students obtained information about dietary supplements via the Internet, they typically purchased the supplements from drug stores. Of the students surveyed, 7.5% who were currently using or used to use dietary supplements experienced adverse effects, with no significant difference between genders (8.8% in male, 7.0% in female). In conclusion, the prevalence of dietary supplement use increased with grade among college students in Japan. Some of them experienced adverse effects. Education may be important to prevent adverse effects resulting from supplement use in college.
