The real value of strategy formulation for information technologyof the related components of a well formulated strategy. It considers the role that some analytical techniques can play in its development. Prescriptive ideas are presented for ensuring success in the evaluation, formulation and the implementation of the strategy and the use of a Portakabin type approach to application projects.

Introduction: of capital importancend oil refining and processing sectors; by 1993 the computer and electronics sector may well constitute the largest single US industry. On some predictions, by the year 2000 the whole IT industry will account for some 10% of world economic activity — a doubling of the 1990 figure (Cane, 1992; Heath and Swinden, 1992).

Assessing the value of strategic information technology investmentsgain a competitive advantage includes investments by such firms as American Airlines, American Hospital Supply Corporation, Avis, Bank America, Citicorp, Digital Equipment Corporation, and General Electric (Cash and Konsynski, 1985; Ives and Learmonth, 1984; Porter and Millar, 1985; Strassmann, 1988; Wiseman, 1985).

Evaluation of information systems investments: towards multiple perspectives is now software on the market to help in assessment of computing facilities. Yet as other contributors to this book demonstrate, there is no commonly accepted framework or methodology for information systems (IS) evaluation.

actice, a survey was undertaken in 1990 of 80 American, British, Australian and New Zealand companies. A one-page survey form was used that provided 15 possible 1ST investment criteria, a means of indicating whether they are used or not, the percentage of projects to which each criterion is applied,

DNA methylation, we focused mainly on the human genome. The following topics in DNA methylation will be treated in detail: (1) The de novo methylation of integrated foreign genomes; (2) the long-term gene silencing effect of sequence-specific promoter methylation and its reversal; (3) the propertie

ted. Cytosine DNA methylation in plants is more rich and diverse compared with animals. It is carried out by the families of specific enzymes that belong to at least three classes of DNA methyltransferases. Open reading frames (ORF) for adenine DNA methyltransferases are found in plant and animal ge

However, one of these repeated sequences (NBL2) displayed predominant increases in methylation in some ovarian carcinomas and Wilms tumors and decreases in others. Furthermore, decreases and increases in CpG methylation can be interspersed within a small s

Leslie Willcocks,Stephanie Lesterchapter, we will focus on three aspects that represent the complexity of epigenetic gene regulation. (1) We will discuss the available data about the DNA methylation system, (2) we will illuminate the interaction between DNA methylation and chromatin regulation, and (3) we will provide an overview o
