More Business School Legislation Needed

Abstract

What Would be a satisfactory accounting system for a particular business is often a real problem to those responsible for installing accounting systems. Also, the problem of adopting business forms and establishing routine procedures cause concern. The writer is attempting to show how the needs of a particular business were satisfied. It is hoped that some of the suggestions made in this article may be incorporated in other accounting systems. It is a well-established fact that many mistakes in adopting accounting systems have been made because a system built for a particular business was adopted by another business whose needs were quite different. It would seem that while all accounting systems have much in common, yet each system should have different features to provide for the different demands upon different businesses.

我国公司财务治理问题研究

财务治理既是一种治理手段,也是一种对财权的制度安排的系统,而且是一套决策程序,也是一种制衡机制,有特定的治理主体、客体、手段、目标和核心的制度安排系统.它不同于公司治理,是一系列协调和规范股东、经营者、债权人等财务治理主体之间财权安排机制的制度安排,规范财务会计信息的生成、呈报,根本目的是为了实现经济利益的合理分配,解决企业契约各方经济利益方面的冲突,最终为顺利实现公司目标提供基础.     

Developing an eService Strategy

"How do I justify investment in eCommerce to a group of senior managers that get their secretaries to print their emails?" was how one manager interviewed for this study summarised his eCommerce problem. This article is about how firms can develop a systematic strategy for delivering service on the web – eService. It starts with the result of a survey of responsiveness to customers in web-based service delivery, part of a study which also includes case studies of companies seeking to justify such investments. It then focuses on understanding the challenge of eService, developing a strategy and making the case for investment. It concludes with suggestions for implementation, including metrics for assessing eService quality.     

Cultural Brands/Branding Cultures

This conceptual paper examines the interface between culture and business, with specific reference to branding. It argues that, while considerable strides have been made in recent years to develop Arts Marketing theory, the subject now needs to take account of wider social and cultural issues. The paper explores the way in which processes of meaning-making have been theorised in consumption and cultural studies. It argues for a view of the symbolic dimensions of branding practices that positions them within the circuit of culture, as a cultural phenomenon. It is argued that brands are symbolic articulators of production and consumption. In this sense, all brands are representational texts, and are socially, not merely managerially, constructed. Different kinds of cultural brands are identified, including cultrepreneurs, cultural corporates and commercial corporates, and their practices in relation to business and culture are discussed. It is suggested that marketing (including branding) is not a neutral analytical repertoire for the study of exchange relationships, but is itself a particular kind of cultural brand, namely an ideological myopia which operates in the service of capital. It is suggested that Arts Marketing practitioners and scholars consider these wider issues in formulating their marketing practices and research strategies.

The artification of luxury: From artisans to artists

Growth is the biggest challenge for a luxury brand in that volume dilutes the brand cachet. In addition, it violates the credo of rarity on which the luxury sector is originally based. This article reveals how the current leading luxury brands use ‘artification,’ a process of transformation of nonart into art, to circumvent the volume problem. Artification takes time and substantial investment. It cannot be undertaken by the brands alone: It requires the active collaboration of art authorities and renowned artists. The goal is to change the status of the brand, of its founder and products, and in so doing, to reinforce the idea of a better-than-ordinary brand whose price and symbolic power are undisputed. It is also strategic for the globalization of luxury: Art is universal.
