Salespeople, although the emissaries of the firm's marketing message, find themselves caught amidst new developments in the market place without the necessary guidelines for facing the new challenges presented to them. The separate development of the fields of Sales Management and Relationship Marketing has left unexplored the transition of salespeople from the 'close the sale' imperative to 'build long-term customer relationships'. Our study explores the selling job in the relational sales context of the services sector and highlights a number of key issues for the development of the theory and practice of relationship orientated sales management. 相似文献

The new Ghanaian government has taken over a serious mortgage. It has to be responsible for the mistakes of the Nkrumah government, whose great development projects often failed because of the country’s insufficient overall development. A valuable survey of the problems in agriculture and industry, which have to be solved by the development policy and which are not always taken into consideration adequately by the rich nations might be given in an interview with Prof. Frederick T. Sai from Ghana. 相似文献

The UN General Assembly has designated the 1978–1988 period as a Decade of Transport in Africa to draw attention to the immense efforts that are—in an internationally coordinated fashion—still needed in this continent. What contribution to Africa’s social and economic development may be expected from major rail and road proejcts? 相似文献

A 3 × 2 experimental design was used to examine the impact of message appeal (fair labor, sex, or a combination of fair labor and sex) and message source (company advertisements or third-party publicity) upon Gen Y consumers' (N = 258) intent to patronize the retailer, American Apparel. Results supported models of hierarchical effects of advertising on patronage intention as well as the inclusion of external variables in the theory of reasoned action. Findings revealed that Gen Y consumers' attitudes toward ad, attitudes toward brand, and purchase intentions toward American Apparel varied by exposure to message appeal in advertisements viewed. Participants' evaluations of source credibility, attitudes toward brand, and purchase intentions toward American Apparel were influenced by message source. Additionally, purchase intentions toward American Apparel were directly predicted by attitudes toward American Apparel and indirectly by perceptions of source credibility. Theoretical and managerial implications are discussed. 相似文献

The authors classify an advertisement as an extended symbolic message (ESM) when the ad's subject and message are presented in a nonliteral format. The study compares the advertising effectiveness of the ESM with that of a literally equivalent message (LEM) when the ESM contains either a salient cue (Experiment 1) or subtle cue (Experiment 2) to a nonliteral interpretation. The results indicate that the audience's need for cognition moderates the effectiveness of the ESM. In comparison with an LEM, exposure to the ESM that contained a salient cue resulted in fewer counterarguments and a more favorable attitude toward the ad and brand among high‐NFC subjects in experiment 1. These results were replicated in experiment 2 among high‐NFC subjects who successfully comprehended the non‐literal subject of the ESM that contained a subtle cue. The implications of these results and directions for future research are discussed. © 2006 Wiley Periodicals, Inc. 相似文献
