This article presents an empirical investigation of how behaviour maintenance is supported or hindered through value creation and destruction in social marketing. Using a longitudinal, netnographic approach, we identify and examine the key facilitators and barriers encountered during the maintenance of physical and mental health behaviours. Data were collected over a 12-week observation period via Twitter from a sample of 242 participants. A total of 5212 tweets were analysed using content and thematic analysis facilitated by NVivo software program. The findings identify key barriers to and facilitators of behaviour maintenance at the individual level (downstream), meso level (midstream), and policy level (upstream) that have an influence on value creation and destruction in social marketing. These findings demonstrate the importance of employing a strategic and integrated approach to social change management.  相似文献

Traditional word of mouth (WOM) involves personal communications among family, friends, and others. Today, social media sites like Facebook offer the possibility of electronic word of mouth (eWOM), a mediated form of WOM. Little is known about the best way for marketers to use social media. Even less is known about international differences in consumer usage of social media and how eWOM influences consumer decision-making. This study helps address that research gap and uses cultural dimensions to compare the use of social media and other information sources for consumer decision-making across 50 countries. The results indicate that the use of information sources that influence online purchase decisions strongly varies by culture. For example, relationship-oriented collectivists rely to a greater extent than individualists on social media, which are an alternative for interpersonal WOM communication. Interestingly culture affects the influence of social media on purchases differently than the influence of traditional WOM through family or friends. Furthermore, there are major differences in online complaint behavior by country, due to cultural variations.  相似文献

Because of increasing levels of competition and decreasing product life cycles, a firm's ability to generate a continuous stream of innovations may be more important than ever in allowing a firm to improve profitability and maintain competitive advantage This paper investigates several issues that are central to an examination of the innovation productivity in a firm. First, the relationship between a firm's commitment to research and development and its innovative outcomes is examined. Two innovative outcomes are analyzed: (1) invention, which focuses on the development of new ideas; and (2) innovation, the development of commercially viable products or services from creative ideas. Invention is measured by the number of patents granted, and innovation is assessed by the number of new product announcements. Second, because many inventions ultimately result in marketable innovations and because patents may provide protection for new products, the relationship between patents and product announcements is also investigated. Finally, the ability of a firm to benefit from its inventions and innovations is studied by examining their separate effects on firm performance, measured as return on assets (ROA) and sales growth. Drawing from a sample of 272 firms in 35 industries over 19 years, the results from a model of simultaneous equations provided support for some of the hypotheses, but several other surprising findings were found. As expected, R&D spending was positively related to patents. This finding is consistent with others who argue that internal research capabilities, particularly those with a strong basic research component, is key to enabling a firm to generate creative outputs. More surprising was the finding of increasing returns to scale to R&D spending. While this contradicts much of the existing research, it is consistent with economic arguments for the advantages of scale in innovation. Also interesting is the finding that, while a significant curvilinear relationship exists between R&D spending and product announcements, it is not the predicted inverse‐U but instead a U‐shaped relationship. Consistent with previous work, product announcements were found to be positively related to both performance measures. A negative relationship was found between patents and both ROA and sales growth. While these findings were unexpected, they are intriguing and call into question the value of patents as protection mechanisms. In addition, these results may be resulting from the rise of strategic patenting, where an increasing number of firms are using patents as strategic weapons. As expected, a positive relationship was found between patents and new product announcements.  相似文献

This paper represents a first attempt to examine empirically the comparative extensiveness of low pay in the third sector against the theoretical backdrop of both the generic labour market literature and the newly emerging specialist third sector literature. It shows that the third sector occupies an intermediate position between relatively high concentrations of low pay in the private sector and low concentrations in the public sector. These differences do not emerge simply because the categories of vulnerable workers identified in the generic labour market literature are less likely to be found in the third sector. Nor do they reflect differences in sectoral industry and occupation composition. Theoretical explanations for these differences are to be found in the third sector literature.  相似文献

This paper discusses the uses of computer algebra within statistics and probability. A distinction is drawn between the use of computer algebra packages to support investigations, by performing calculations, ankl their use to implement structure; to build in elements of a theory (such as stochastic calculus or the Taylor string theory of Barndorff Nielsen and others) as a preliminary to research investigations. Brief surveys are given of instances in the literature of use of computer algebra in probability and statistics. Two examples of implementations of structure are discussed, both drawn from the author's own work with the computer algebra package REDUCE. One is a simple demonstration using moments of the Poisson distribution. The other is itovsn3 , an implementation of the semimartingale stochastic calculus. It is described how itovsn3 may be used to derive the characteristic function of the Lévy stochastic area, following a proof due to S. Janson. Prospects for future work and for work in progress are discussed.  相似文献

In Theory Z-style management everybody participates in corporate decision making. This more open process should give us fewer Pintos, Love Canals, and massive international payoffs as executives are forced to expose their reasoning to the moral sensibilities of the whole corporation. So far everything looks good. But we are a long way from showing that only corporations so managed can be fully moral. Yet Dwiggins seems to believe this, putting his faith in the basic goodness of the many while virtually dismissing the managers as mere technicians. This is too slick; even if it describes our average corporation today, there are plenty of less radical changes which can also produce the desired moral corporation. Good leadership which acts on their commitment to improve the company is surely one historically respectable alternative; cynicism about the present crop of leaders should not distract us from investigating this route. Finally, I wonder if Dwiggins can consistently urge us to embrace a full-scale Theory Z organizational structure, given his position on the place of ethics and profitability.  相似文献

Abstract We apply a regression discontinuity approach to determine incumbency advantages in the Canadian Parliament, finding that incumbents enjoy a 9.4–11.2% increased probability of winning over non‐incumbents. Owing to the presence of multiple parties, an incumbency advantage in terms of vote share does not always translate to an increased probability of winning, because incumbents do not necessarily obtain votes from their closest opponent. Also, under the assumption that strategic exit is not an issue, we are able to split the incumbency advantage into party incumbency and individual candidate incumbency components, finding that the advantage is almost entirely due to the individual.  相似文献
