Supplement and food manufacturers are permitted to make certain health claims from emerging science on package labels, provided
that a qualifier which indicates the strength of science supporting the claim is used. The Food and Drug Administration has
proposed four levels of strength of science; however, the research to date has demonstrated that consumers cannot distinguish
between these four levels. The current study tests whether iconic and comparative representations are effective at conveying
strength of science. We find that both displays are effective and that consumers' perceptions of level of science are significantly
influenced by industry trust and processing involvement. 相似文献

Virtual stores are Internet-based innovations that influence the dynamics of consumer choice making. Utilizing the attitude-to-behavior theory, theory of reasoned action, technology acceptance model, functional theory of attitude, causal theory of action, and prior literature, we develop and empirically evaluate a model that describes consumer purchase decisions in a virtual store. We test the model using data collected from validated survey instruments for each of the constructs utilizing the structured equation modeling technique. The model helps in the design of virtual stores by describing how individuals who visit such stores can be induced to purchase from virtual stores. It describes that perceived usefulness, perceived behavioral control, and perceived peer influence impact attitude toward purchasing from a virtual store. Attitude toward purchasing from a virtual store, in turn, influences the actual purchasing from a virtual store. We discuss the implications for the design of virtual stores that lead to purchase decisions. 相似文献

Work environments have grown substantially more complex over the years. Teams are increasingly distributed, and presented with a variety of different communication technologies, e.g., e-mail, instant messaging, cellular phones, pagers, and intranet applications, for use in distributed collaborative activities. Further, individuals often belong to multiple teams concurrently. This study explores how virtual team members structure their use of multiple media to attain strategic goals in complex work environments. A grounded theory approach was used to analyze data gathered from forty interviews of information technology workers. Our results indicate that there are two primary structures individuals employ when making use of multiple media: sequential and concurrent. Sequential combinations are of three types: redundant, serial, or complementary, while concurrent combinations are of two types: independent or complementary. Further, individuals strategically use multiple media to accomplish specific communication goals beyond simply transmitting the message, such as message acknowledgement, enhancement of mutual understanding, and participation in multiple communication interactions. The implications of these findings for research and practice are discussed.Both authors contributed equally to this paper. 相似文献

This paper describes the sources and methods used in assembling a microconsistent regional data set for Canada for 1981 for use in counterfactual general equilibrium policy analyses focussing on regional impacts of government policies. A microconsistent data set at the regional level requires assembling detailed consistent accounts of production and demand by region, of interregional and international trade flows, and of transactions involving multiple levels of government. For many or most countries, the data requirements associated with regional general equilibrium analysis preclude this form of work. But because of the substantial progress made in recent years in developing provincial data sources in Canada, such as the provincial input-output tables and the provincial economic accounts, the situation in Canada is different. Using these data, it is possible to construct an interregional microconsistent benchmark data set at a suitable level of commodity detail for subsequent model use. This data set has already been used in an initial evaluation of a number of Canadian regional issues (see Trela and Whalley (1985)). The methodology used follows that presented in an earlier paper of ours (St-Hilaire and Whalley (1983)) which described the construction of a 1972 national data set for Canada developed for tax policy analysis. 相似文献

The Kalman filter is proposed as a method for estimating the value of nontrading securities during periods when other securities
are trading. The method also provides confidence intervals that indicate the degree of uncertainty regarding estimated value.
The method is applied to the Major Market Index during the principal days of the 1987 stock market crash. Our results indicate
that nonsynchronous trading explains a small but significant portion of the cash-futures spread that prevailed during these
days. 相似文献

In this article, we study the heterogeneity of fruit and vegetable consumption patterns in France. A finite mixture of AIDS models is used to describe food demand patterns revealing different preferences over distinct classes. We obtained six different clusters, which reflect specific socio-demographic characteristics and different income and price elasticities. This approach is appropriate for targeting specific public nutritional policies. Our main results show that unlike the other clusters in which the usual price and income policy tools may be used, the lowest income cluster with the lowest consumption, remains insensitive to economic variables. 相似文献

The focus of this study is the habitual speculator in commodity futures markets. The speculator's activity broadens a market, creates essential liquidity, and performs an irreplaceable pricing function. Working knowledge of the profiles and motivations of habitual speculators is essential to both market theorists and policy makers. Responses to a 73-question survey were collected directly from retail commodity brokers with offices in Alabama. Each questionnaire recorded information on an individual commodity client who had traded for an extended period of time. The typical trader studied is a married, white male, age 52. He is affluent and well educated. He is a self-employed business owner who can recover from financial setbacks. He is a politically right-wing conservative involved in the political process. He assumes a good deal of risk in most phases of his life. He is both an aggressive investor and an active gambler. This trader does not consider preservation of his commodity capital to be a very high trading priority. As a result, he rarely uses stop loss orders. He wins more frequently than he loses (over 51% of the time) but is an overall net loser in dollar terms. In spite of recurring trading losses, he has never made any substantial change in his basic trading style. To this trader, whether he won or lost on a particular trade is more important than the size of the win or loss. Thus he consistently cuts his profits short while letting his losses run. He also worries more about missing a move in the market by being on the sidelines than about losing by being on the wrong side of a market move; that is, being in the action is more important than the financial consequences. Participating brokers confirmed that for the majority of the speculators studied, the primary motivation for continuous trading is the recreational utility derived largely from having a market position. © 1998 John Wiley & Sons, Inc.

This research investigated how secondary school technology teachers planned and implemented units that enabled students to access authentic technological practice through their contact with a community of practice (CoP). It was found that when teachers plan to access a community of practice for their students a complex dance-style relationship develops between the three parties involved. Unplanned interactions can have a significant effect on the planned teaching unit. If teachers are reflexive to the demands of the student and the CoP representative, there is the potential for the development of teaching programmes with technological outcomes that reflect authentic technological practice. 相似文献

Governments worldwide have launched various schemes to promote recycling by individuals, from legislation to voluntary and mandatory policies, waste charging, kerbside collection, waste separation bins, and promotional campaigns. Much remains to be done, however, in terms of understanding the psychological relationships among consumers' attitudes, intentions, and behaviours when it comes to recycling. This study was designed to examine recycling intention through the lens of the theory of planned behaviour (TPB). Using online survey, we recruited participants (n = 827) through an online survey platform ( mturk.com ). The results show that TPB can predict consumers' intention to recycle. It was further found, however, that attitude towards recycling did not predict intention to recycle. The findings presented here have significant implications for policymakers and practitioners who are interested in inculcating recycling intention and behaviours in members of the public. This study extends the TPB in the context of recycling. There is a need to examine the theories' explanatory power in different research settings and context. Moreover, regulations and policies on recycling continue to evolve. For example, recently in 2018, Australia is banning plastic bag. Consequently, the new policy will affect people's perception towards recycling. Hence, continued research on recycling is needed. 相似文献
