A key challenge in information retrieval is the use of contextual evidence within the ad-hoc retrieval. Our contribution is particularly based on the belief that contextual retrieval is a decision making problem. For this reason we propose to apply influence diagrams which are extension of Bayesian networks to such problems, in order to solve the hard problem of user based relevance estimation....

BACKGROUND There has been insufficient research attention to alcohol industry methods of influencing public policies. With the exception of the tobacco industry, there have been few studies of the impact of corporate lobbying on public health policymaking more broadly. METHODS We summarize here findings from documentary analyses and interview studies in an integrative review of corporate effo...

The tactics used by the tobacco industry to resist government regulation of its products include conducting public relations campaigns, buying scientific and other expertise to create controversy about established facts, funding political parties, hiring lobbyists to influence policy, using front groups and allied industries to oppose tobacco control measures, pre-empting strong legislation by ...

Therefore now, without even ever discussing the subject with the offi ce-bearers of IAOH till date, he has chosen to pose himself as “a martyr” for the cause in the international community or to appease Ban Asbestos lobby for the reasons only known to him. I am also surprised that a reputed journal like IJOEH is letting disgruntled professionals use it as a forum to achieve their personal agend...

a r t i c l e i n f o Keywords: Dual capabilities New product market performance Exploratory learning Exploitative learning This article investigates how dual capabilities of influencing external environments (i.e., the capabilities to influence government and to influence industry) can affect new product market performance (NPMP) in emerging markets and how organizational learning (via explora...

We consider an active information system, which aims to notify a traveler timely about a likely delay. Besides providing the right content, it should also wait for the best time for notification. This is especially true for mobile information services, where every notification may irritate the recipient. We formulate and solve such a problem involving best choices both for content and time of n...

In this paper we present a new class of complexity measures, induced by a new data structure for representing k-valued functions (operations), called minor decision diagram. The results are presented in terms of MultiValued Logic circuits (MVL-circuits), ordered decision diagrams, formulas and minor decomposition trees. When assigning values to some variables in a function f the resulting funct...

This paper is about reducing influence dia­ gram (ID) evaluation into Bayesian network (BN) inference problems. Such reduction is interesting because it enables one to read­ ily use one's favorite BN inference algorithm to efficiently evaluate IDs. Two such reduc­ tion methods have been proposed previously (Cooper 1988, Shachter and Peot 1992). This paper proposes a new method. The BN in­ feren...

This study examines some of the important organizational consequences of the fashion phenomenon in information technology. An IT fashion is an information technology transitorily collectively believed as new, efficient, and at the forefront of practice. Using data collected from published discourse and annual corporate IT budgets, I have found that companies associated with IT fashions did not ...
