Zooming-in zooming-out: a novel method to scale up local innovations and sustainable technologies

Based on two case studies from Bangladesh and Benin, the role of video in scaling up sustainable rice technologies is assessed. Both process and outcomes of participatory research increased the effectiveness of educational videos. At the same time, during the production of the videos researchers and development workers learnt about local innovations and changed their attitude towards working with farmers. To increase impact, learning topics should have a regional relevance. Hence a novel method called zooming-in zooming-out is presented. It starts with a broad stakeholder consultation to define regional issues. Only then are communities approached to get a better feel about their ideas, their innovations and the words they use in relation to the chosen topic (zooming-in). Key learning needs are defined and videos are produced in close consultation with the end-users. Consequently, while showing the draft videos to more villages (zooming-out), more insights are gathered about the innovations and their socio-cultural context, and further adjustments made. Based on a few well-selected local innovations, and merged with scientific knowledge, these videos were able to explain underlying biological and physical principles. The more these principles resonated with what farmers already knew and did, the more video became useful as a stand-alone method. Facilitation increased adoption of sustainable technologies, but was not always a prerequisiste.     

品牌管理策略:王老吉品牌成功的原因

品牌自身并没有销售力,但品牌却与消费者的信任感、忠诚度相结合显示出强大的力量。品牌塑造是一个动态的演进过程,企业应首先根据产品的特点进行品牌定位,然后开展有力的品牌扩展。在品牌扩展过程中,品牌文化的内涵可以是多元化的,而产品精神应该是单一的。品牌推广的目的是通过对产品精神的强化使产品更具吸引力和说服力,为产品创造核心竞争优势。

关于“巴山舞”的继承推广与发展的调查研究

以湖北省普通高校巴山舞为研究对象,采用文献资料法、问卷调查法及统计分析法。笔者结合巴山舞的特点：强烈的民族性、鲜明的时代性、高雅的艺术性、简易推广性及比赛的宽松性,对巴山舞的现状进行了分析：当地跳巴山舞的人们比周边地方的要多,不过周边地方巴山舞开展的前景也不错。要很好地开展巴山舞要以民族特色、地域特色为基础,突出重点,与时俱进,不断对巴山舞进行创编,形成特色。

奢侈品的品牌延伸评价:广告类型、契合度的影响

近年来,奢侈品消费在中国增长迅速,中国市场已成为奢侈品消费的重要市场。品牌延伸是奢侈品牌拓展市场的重要战略,但这方面的学术研究却相对单薄。本文以奢侈品牌为研究对象,通过实证研究探讨了在不同广告类型下,延伸契合度对消费者延伸评价的影响。研究发现,对于奢侈品牌,延伸契合度与广告宣传类别对消费者的延伸评价都存在显著影响,且两者之间存在交互作用。具体而言,奢侈品进行品牌延伸时,与母品牌契合度高的延伸产品更能获得消费者较高的评价;与宣传延伸品的产品特征相比,宣传延伸品的品牌形象更能提高延伸吸引力与购买欲望。此外,在低延伸契合度下,宣传延伸品的品牌形象产生的这种积极影响更为显著。     

煤炭企业外延成本的管理与控制

根据煤矿生产及成本构成的特点,将对煤炭成本影响较大,而且在生产过程中难以管理与控制的成本称之为＂外延成本＂。研究表明：矿井规划设计与建设、煤矿技术改造、煤矿服务体系和管理体系对成本影响较大,应该加强煤矿技术改造,完善煤矿的服务体系和管理体系,合理规划和建设矿井等。     

Does poor fit always lead to negative evaluations? Extension advertising and perceived brand quality

This article investigates the moderating roles of advertising strategy (relational vs. elaborational) and perceived parent brand quality on the influence that parent brand–extension fit exerts on consumer evaluations of both extensions and the parent brand. Two studies manipulate fit in terms of either brand concept consistency or product feature similarity. Lower fit results in negative consumer responses, yet an elaborational advertising strategy mitigates the negative effects of lower fit on extension evaluations. This mitigating effect is stronger for high quality than for average quality brands. The results also indicate extension feedback effects for the parent brand, suggesting that elaborational advertising strategies may reduce the impact of fit on parent brand feedback effects. This latter link is not moderated by parent brand quality.
