Conjoint Analysis (CA) is a very popular class of methods for measuring consumer preferences, both in research and practice. However, since a couple of years, the Analytic Hierarchy Process (AHP) is being discussed in this field as well. Several empirical studies have shown the general potential of AHP, particularly in complex product evaluation tasks consisting of many attributes. But, in spit...

SYSTEMS EXEMPTED FROM CERTAIN PROVISIONS OF THE ACT: The Attorney General has exempted this system from subsections (c)(3) and (4), (d), (e)(2), (e)(3), (e)(4)(H), (e)(8), (f) and (g) of the Privacy Act pursuant to 5 U.S.C. 552a(j). Rules have been promulgated in accordance with the requirements of 5 U.S.C. 553(b), (c) and (e) and have been published in the Federal Register and codified at 28 C...

OBJECTIVE To assess if commercially sponsored trials are associated with higher success rates than publicly-sponsored trials. STUDY DESIGN AND SETTINGS We undertook a systematic review of all consecutive, published and unpublished phase III cancer randomized controlled trials (RCTs) conducted by GlaxoSmithKline (GSK) and the NCIC Clinical Trials Group (CTG). We included all phase III cancer R...

License agreements constitute between 20-33% of all strategic alliances in sectors commonly identified as likely candidates for an endogenous fixed cost (EFC) model; namely biotechnology and chemicals among others. We develop a model of endogenous market structure and fixed (sunk) cost R&D investment based on Sutton (1998; 2007) and include the ability of firms to license their technology to (p...

Information privacy has gained increased attention in recent years. This paper focuses on a particular aspect of privacy, i.e., personal information privacy. In this paper a conceptual framework is developed based Westin’s theory of Personal Information Privacy (PIP). Concourse theory and Q-methodology was used alongside the literature and the New Zealand Privacy Act 1993 to develop a Q-sort qu...

BACKGROUND In phase II trials of cytotoxic agents, a multinomial phase II design incorporating early progression and response end points was shown to perform more efficiently than designs based only on response. We undertook a study to evaluate the performance of these designs in trials of targeted agents using the actual phase II data. PATIENTS AND METHODS Using best response data from seque...

Clustering in data mining is a discovery process that groups a set of data so as to maximize the intra-cluster similarity and to minimize the intercluster similarity. Clustering becomes more challenging when data are categorical and the amount of available memory is less than the size of the data set. In this paper, we introduce CBC (Clustering Based on Compressed Data), an extension of the Bir...

For a strongly connected Extended-Free-Choice Net (EFC-net) N the algorithm given in this paper either nds a cover of S-components or recognizes that N is not well-formed. Well-formedness denotes the existence of a live and bounded marking for N. The algorithm is also adaptable to compute a cover of T-components. The time complexity is O(jPjjTj). According to the Rank Theorem, nding a cover of ...

Vidhi Thakkar and Terrence Sullivan have done a careful and thought-provoking job in trying to establish comparable estimates of public spending on health services and policy research (HSPR) in Canada, the United Kingdom and the United States. Their main recommendation is a call for an international collaboration to develop common terms and categories of HSPR. This paper raises two additional q...
