Awareness, use, and perceptions of biodiesel: A comparison of consumers in Belgium and the United States

Belgian (N = 61) and American (N = 134) fuel consumers were interviewed in the summer of 2012 to determine their awareness, use, and perceptions of biodiesel. Consumers who were aware of biodiesel were asked their perceptions. A significantly P \u3c 0.0001) higher percentage of Belgian consumers (78.7%) reported owning or driving a diesel vehicle compared to American consumers (9.0%). Belgian and American consumers moderately agreed biodiesel is a high-quality fuel. For both Belgian and American consumers, there was no significant association between owning a diesel vehicle and being aware of biodiesel or having purchased biodiesel. Although Belgian and American consumers agreed that using non-food crops for biodiesel is justified, Belgians were significantly less supportive than American consumers of using food crops for biodiesel. Both Belgian and American consumers disagreed with the statement “I would never use biodiesel”, and the two sets of consumers moderately disagreed that diesel engines would not run properly on biodiesel. Belgian and American consumers agreed that global warming is increasing; however, American consumers were more positive about the potential of biodiesel to reduce harmful exhaust emissions and global warming. Belgian consumers moderately agreed and American consumers agreed that biodiesel is better to use because it is made from renewable resources. Belgian and American consumers generally show similar perceptions of biodiesel, with the exception that American consumers were more positive toward the environmental and renewable aspects of biodiesel use. Recommendations for further research include gaining a better understanding of the potential positive influences that impact consumers’ perceptions of biodiesel

Motor activity and depression in juvenile delinquents

Thesis (Ph.D.)--Boston UniversityThe purpose of this study was to test certain predictions derived from a theory of juvenile delinquency. This theory states that delinquency is related to increased motor activity. This increased motor activity is the child's defensive process against experiencing an underlying depression. This depression is caused by the actual or emotional loss of the parent figure in an early stage of developnent. From the theoretical statements, developed by Dr. Irving Kaufman, the following hypotheses were derived: When the juvenile delinquent is placed under tension; (1) the level of depression is higher than when the tension does not obtain, (2) the level of motor activity is higher than when tension is reduced, and (3) the level of phantasy directed toward the environment and action is higher than when tension is reduced. The subjects of this study were thirty consecutively adjudicated male juvenile delinquents between the ages of twelve and sixteen. Each subject was tested in two situations; a tension situation immediately prior to the first court appearance, and a reduced tension situation, two to six weeks later when the child learned the court's disposition of his case; i.e., probation or committment. Depression was measured by the Rorschach scores associated with depression. Survey of the literature led to the selection of six indicators. These were: (1) reduced R, (2) increased reaction time, (3) decreased C, (4) decreased M, (5) more frequent responses involving C', and (6) increased F+%. Shift in these measures in the two situations constituted the measure of depression. [TRUNCATED

Awareness, Use, and Perceptions of Biodiesel by Belgian and American College Students

Biodiesel is a renewable liquid transportation fuel with potential to extend petroleum supplies and reduce tailpipe emissions of particulate matter, unburned hydrocarbons, andcarbon monoxide (CO)and reduce life-cycle carbon dioxide (CO2)emissions relative to petroleum diesel.However, little is known about how various groups, eitherinternationally or domestically, view biodiesel.This study examined Belgian and Americancollege students’ awareness, use, and perceptions of biodiesel.A higher percentage of Belgian students versus American students reported driving diesel automobiles (60%and 17%, respectively) and being aware of biodiesel (100%and 86%, respectively).However, only 4% of either Belgian or Americanstudents had purchased biodiesel.Belgianstudents were undecidedand Americanstudents slightly agreed there were renewable and environmental benefits ofbiodieseluse.Both Belgian and Americanstudents were undecided about biodiesel quality, with Belgian students being more uncertain.Belgian and Americanstudents were also undecidedif there were negative externalities associated with biodiesel.Both groups tended to agree that continued long-term reliance on fossil fuels is not sustainable; however, Belgian students agreed more strongly than Americanstudents.While there were significant differences between Belgian and Americanstudents, both groups were largely undecided about biodiesel quality and the food and economic consequencesof biodiesel production and use; differences were primarily in the degree of uncertainty.Both groups (especially Belgian students) were concerned about continued reliance on fossil fuels.Given the low level of use and the high degree of uncertainty, efforts should be made to educate Belgian and Americancollege students about biodiese

Poultry Production Messaging in Two National-Circulation Newspapers

Consumers are concerned about the use of antibiotics and hormones in poultry. News media is the primary way consumers gain knowledge about this subject. This study assessed articles in an effort to describe and compare coverage of antibiotic and hormone use in poultry production from The New York Times (NYT) and The Wall Street Journal (WSJ) between 1994 and 2014. Content analysis methodology was used to assess selected articles (N = 265) to identify key messages about antibiotic and hormone use in poultry production, article type, type by year, and complete a comparison of focus, frames, and emergent themes. Five emergent themes were identified: 1) consumers awareness of and concern for antibiotic/hormone use in poultry production (NYT 38.8%, WSJ 51.2%); 2) the role of antibiotic use in poultry production in increased levels of antibiotic-resistant bacteria (NYT 43.8%, WSJ 24.4%); 3) regulation of antibiotic use in poultry production (NYT 35.0%, WSJ 31.7%); 4) purpose of antibiotic/hormone use in poultry production (NYT 32.5%, WSJ 29.3%); and 5) transparency of antibiotic use poultry production practices (NYT 15.0%, WSJ 12.2%). Articles were primarily news stories, and there was an increase in articles focused on antibiotic and hormone use in poultry over the 20-year period. NYT was 8.8 times more likely to write an editorial on one of these topics than was the WSJ. Recommendations include increased understanding and addressing consumer concern about antibiotic and hormone use in poultry production, increased transparency, and improved relations with media contacts who cover poultry production issues
