An Exploration of Managerial Views on Positioning Services in Ghana

ABSTRACT

The paper constitutes an analysis of the views of managers of service firms on positioning strategies in Ghana. The research employed a qualitative research method. Data were collected from 21 service managers and analyzed using content analysis procedures. The results indicate that for service managers, the perceived dominant positioning strategies of their organizations were: service quality, customer relationship, innovation, availability of service, community support, and leading organization, among others. The findings suggest that the dominant managerial views of Ghanaian service managers form a ‘hybrid’ of those of the Western manager. This research is important in clarifying this position. Additionally, as an exploratory piece, the study provides bases for further research on a topic in Ghana with a rather scant evidence of research.     

浅谈柬埔寨王国水利灌溉项目测绘中RTK的应用

本文立足测量学中全球定位系统实时动态测量(RTK)技术进行系统论证,从概念理论的阐释,到该测量方法在实际水利测量工程中的具体应用。通过对柬埔寨王国水利灌溉测量结果的精度分析,得出了RTK的测量精度是可以达到工程前期测量的精度,并且结合水利工程测量实例说明了RTK具有工作效率高、定位精确和操作简单易于使用等特点。     

浅析攻丝质量问题及攻丝胎具的应用

攻丝是机械加工中最常用的加工工序之一,也较容易出现问题,在一般的金属加工中,通常是迅速切除金属并形成光洁表面,工序就算终结,但攻丝却完全不是这样,而不论在何种情况下,丝锥的正确选择都会对攻丝的效果产生截然不同的影响,本文章介绍了影响攻丝质量的几个因素,提出了改善该因素的解决方法,仅供参考。     

Inducing the adoption of emerging technologies for sustainable intensification of food and renewable energy production: insights from applied economics*

Emerging advances in sustainable intensification technologies have the potential to transform land use and crop management approaches in ways that can increase resource productivity and reduce adverse environmental impacts of agricultural production. This paper describes emerging technologies that can sustainably intensify food and renewable energy production. We apply the findings from studies examining the adoption of technologies with similar stylized features to provide insights about the incentives and barriers for the adoption of these emerging technologies. We also present a landscape-based systems approach, based on welfare economics, to go beyond relying on a positive approach to explain observed adoption decisions to examining normative questions about the optimal mix, level, and location of adoption of these technologies to achieve desired societal outcomes. We conclude with a discussion of the insights from applied economics for the design of policy incentives to achieve these outcomes.     

债券溢折价实际利率摊销法的再探讨

基于实际利率法的两项基本规定推论出债券溢折价摊销额、利息收入、债券投资账面价值的计算规律,据此认为实际利率法是一种集精确性与简便性为一体的摊销方法,并非会计界认为的二者不可兼得。     

全站仪的误差分析及精度控制在水利工程测量中的研究

水利工程是国民经济建设过程中非常重要的建设内容,能够为人们的生产生活提供极大的便利,这就需要保证水利工程测量工作的准确性。在水利工程测量过程中,常用的测量工具就是全站仪,做好其误差分析与精度控制工作是非常必要的,本文就主要针对此予以简单分析。

地方政府在新农村建设中的定位

新农村建设的序幕已经拉开,历史赋予了地方政府艰巨的使命。面对新农村建设中各种错综复杂的矛盾,需要充分了解新农村建设的实质及其存在的矛盾,地方政府作为诱致性制度变迁与中央政府强制性制度变迁之间转化的桥梁,要解决城乡发展的差距和日渐深化的农村的贫困,要使农村进入一个更大的关联社会,参与到新的社会交换系统中来,从而消除社会结构不完善的缺陷,地方政府的合理定位成为新农村建设的关键。     

Link16数据链导航功能实现与改进

基于同步的相对导航与精确定位技术是Link16数据链运行的关键。针对国内文献对该 技术介绍较少的情况,分析了相对导航的基本原理,研究了利用往返计时报文实现精确同步 的方法和步骤,建立了相对导航解算方程以及相对栅格与地理栅格坐标之间的数据转换模型 ,最后提出了一种用GPS/IMU数据融合和卡尔曼滤波方法提高导航精度的方案。应用结果表 明,该方案能显著提高数据链的导航精度。     

Institutional stakeholdings and better-informed traders at earnings announcements

Utama and Cready [Utama, S., Cready, W.M., 1997. Institutional ownership, differential predisclosure precision and trading volume at announcement dates. Journal of Accounting and Economics 24, 129–150] use total institutional ownership to proxy for the proportion of better-informed traders, an important determinant of trading around earnings announcements. We argue that institutions holding small stakes cannot justify the fixed cost of developing private predisclosure information. Also, institutions with large stakes generally do not trade around earnings announcements since they are dedicated investors or face regulations that make informed trading difficult. However, institutions holding medium stakes have incentives to develop private predisclosure information and trade on it; we show that their ownership is a finer proxy for the proportion of better-informed traders at earnings announcements.
