An effective business model is the core enabler of any company's performance. Business model innovation is not only becoming more and more important due to increasing and globalizing competition, but also an enormous challenge, both theoretically and practically. Although many managers are eager to consider more disruptive changes to their business model, they often do not know how to articulate their existing or desired business model and, even less so, understand the possibilities for innovating it. One of the steps toward developing more theoretical insight and practical guidelines is the identification of types and the development of a typology of business model innovations. Ten retrospective case studies of business model innovations undertaken by two industrial companies provide the empirical basis for this article. We analyzed the characteristics of these innovations as well as their success rates. The findings suggest that there are indeed various business model innovation types, each with its own characteristics and challenges. 相似文献
Over the past five years the Artificial Intelligence Center at SRI has been developing a new technology to address the problem of automated information management within real- world contexts. The result of this work is a body of techniques for automated reasoning from evidence that we call evidential reasoning. The techniques are based upon the mathematics of belief functions developed by Dempster and Shafer and have been successfully applied to a variety of problems including computer vision, multisensor integration, and intelligence analysis.
We have developed both a formal basis and a framework for implementating automated reasoning systems based upon these techniques. Both the formal and practical approach can be divided into four parts: (1) specifying a set of distinct propositional spaces, (2) specifying the interrelationships among these spaces, (3) representing bodies of evidence as belief distributions, and (4) establishing paths of the bodies for evidence to move through these spaces by means of evidential operations, eventually converging on spaces where the target questions can be answered. These steps specify a means for arguing from multiple bodies of evidence toward a particular (probabilistic) conclusion. Argument construction is the process by which such evidential analyses are constructed and is the analogue of constructing proof trees in a logical context.
This technology features the ability to reason from uncertain, incomplete, and occasionally inaccurate information based upon seven evidential operations: fusion, discounting, translation, projection, summarization, interpretation, and gisting. These operation are theoretically sound but have intuitive appeal as well.
In implementing this formal approach, we have found that evidential arguments can be represented as graphs. To support the construction, modification, and interrogation of evidential arguments, we have developed Gister. Gister provides an interactive, menu-driven, graphical interface that allows these graphical structures to be easily manipulated.
Our goal is to provide effective automated aids to domain experts for argument construction. Gister represents our first attempt at such an aid. 相似文献
Over the last 30 years, the victims' rights movement has expanded the role of victims in the American criminal justice system. As a result of this movement, judges, prosecutors and parole boards must now hear victims' views at all stages of the criminal justice process, including plea bargains, and sentencing and parole decisions. Legislative efforts have been spearheaded by victims' families, and legislation has been named after deceased victims. Also, victims' families can now view executions in states across the country. The victims' right movement assumes that the criminal justice system should privilege victims' interests over those of society. In so doing, it denies society as a consideration, which is tantamount to a denial of society itself. This article positions victims' rights' denial of society within the current conjuncture, marked as it is by the contradiction between neoliberalism and American liberalism. Victims' rights' denial of society is an expression of the denial of society implicit in American neoliberalism, which seeks to privilege individual interests over those of society. This paper argues that victims' rights is a powerful element of the neoliberal project for three reasons. First, victims' rights imputes the authority of legal discourse to neoliberalism's denial of society. Second, important actors in the rise of neoliberalism have also worked to establish victims' rights. Finally, victims' rights comprehensively circulates throughout America and offers powerful points of identification that incorporate Americans into the victims' rights formation. I explore the denial of society in three victims' rights practices: naming criminal legislation after crime victims and passing such laws in honour of victims; allowing victims' families to view executions; and prosecutors, judges and police personnel making legal decisions according to victims' wishes. I examine the consonant denial of society in three neoliberal practices – monetarism, supply-side economics and welfare reform – and demonstrate how neoliberal advocates like Bill Clinton, Ronald Reagan and Paul Gann worked to advance victims' rights. I also describe the production, consumption and comprehensive circulation of victims' rights texts. Finally, I consider Cultural Studies' unique contribution to legal studies. 相似文献
