Face To Face

Prevention strategies for non-communicable diseases (NCDs) are a global priority as it has been estimated that NCDs will account for around 73% of worldwide mortality by the year 2020. The adoption of diets that are low in saturated fat, free sugars, and red and processed meats and higher in unsaturated fats, wholegrains, fruit, and vegetables have been shown to reduce the risk of NCDs. With increasing internet use, several nutrition interventions are now being conducted online as well as face-to-face, however it is unclear which delivery method is most effective. Although a consumer preference toward face-to-face dietary advice delivery has been identified previously, interest in delivering web-based dietary advice, and in particular personalized nutrition (PN), has been rising, as internet delivery may be less costly and more scalable. This review compares published face-to-face and web-based dietary interventions to give insight into which dietary method might be more effective for PN. In total, 19 peer-reviewed randomized controlled trials were identified for inclusion in the review. The majority of face-to-face nutrition interventions were successful at facilitating dietary change. Results from web-based nutrition interventions suggested that personalized web-based nutrition interventions may be successful at inducing short-term dietary change compared to standardized dietary interventions, however, minimal evidence of long-term impact has been found across both delivery methods. Results of a trial that compared face-to-face with web-based diet intervention found significantly greater dietary changes in the face-to-face group compared to web-based and control groups. Further controlled comparative studies and cost-benefit analysis are needed to assess whether web-based methods can be used in place of face-to-face interventions for achieving dietary change.

The design of electronic financial services differ crucially from that of conventional services due to their inability to adjust sporadically to the needs and wants of consumers, as adaptability is strongly associated with the human component of services production. In this regard, identification of the motives driving adoption and consumption is the precondition for successful implementation of electronic services. This article reports the results of a survey conducted for an R&D project with the objective to design an innovative and comprehensive wealth management service for consumers, a service that is offered mainly via the internet. In this study, the authors found that the conventional wisdom of mainstream finance and technology adoption theories, return-risk thinking, and cost-benefit analysis of product characteristics were insufficient to predict adoption. Rather, the adoption decision appears to be dominated by the perceived fit between the new service and the consumer’s established consumption patterns.

The Us

At the heart of most food, nutrition, and health decisions and concerns is an economic issue. Consequently, understanding some basic economics is imperative to evaluate the likely effectiveness of food and nutrition policies or interventions, especially those designed to operate through economic channels. Section I of the book provides the fundamentals of nutrition. Section II provides the fundamentals of consumer economics, from both the neo-classical and behavioral economics perspectives. Section III gives an overview of the US food system and the fundamentals of food production economics. Section IV gives the fundamentals of market analysis, including horizontally and vertically related markets. Section V gives an overview of cost effectiveness and cost benefit analysis of nutrition interventions. The general structure for most chapters is to first motivate the importance of the topic, present the economic approach to analysing the topic, intersperse the text with some examples and questions applying the concepts, and conclude with what has been found in the empirical literature related to the topic. A hypothetical conversation between a nutritionist and an economist runs throughout the book to help give the book a conversational feel and motivate and summarize each chapter.

It is clear that transactional behavior consistency is a prerequisite and basis for construction of a reliable services-based business application. However, in previous works, maintaining transactional consistency during exception handling was ignored. Maintaining transactional consistency requires functionality for rolling back some operations and revoking uploaded data. Replacing only the failed service will eventually lead to overall business application failure. In this study, we take fully into account the behavioral consistency of transactional services and propose two effective self-healing mechanisms for service-based applications. If a service enters into potential failure condition, a rescheduling mechanism is triggered to maintain consistent transactional behavior and to ensure reliable execution; if a service fails during execution, the compensation operation is triggered and the system will take action to ensure transactional behavior consistency. Meanwhile, cost-benefit analysis with compensation support is proposed to minimize the dynamic reselection cost. Finally, the experimental analysis shows that the proposed strategies can effectively guarantee the reliability of Web-based applications system.

Dietary Feedback

Given the complex and varied nature of individual characteristics influencing dietary behaviors, personalized dietary advice may be more effective than generalized “one-size-fits-all” advice. In this paper, we describe a web-based personalized nutrition system for improving the quality of overall diet in the general adult population. The development process included identification of appropriate behavior change techniques, modification of dietary assessment method (Meal-based Diet History Questionnaire; MDHQ), selection of dietary components, and a personalized dietary feedback tool. A pilot study was conducted online among 255 dietitians. Each completed the MDHQ, received his/her own dietary feedback report, and evaluated the relevance of the report based on 12 questions using a 5-point Likert scale from “totally disagree” (score 1) to “totally agree” (score 5). The mean value of overall acceptability score of dietary feedback report was 4.2. The acceptability score was, on average, higher in plausible energy reporters (compared with implausible energy reporters), participants who printed out the report (compared with those who did not), and those spending ≥ 20 min to read the report (compared with those spending < 20 min). This is the first attempt to develop a web-based personalized nutrition system in Japan, where dietitians were broadly supportive of the dietary feedback report.
