This paper presents a self-contained introduction to a general conjoint measurement framework for the analysis of nontransitive and/or incomplete binary relations on product sets. It is based on the use of several kinds of marginal traces on coordinates induced by the binary relation. This framework leads to defining three general families of models depending on the kind of trace that they use....

This paper studies strict preference relations on product sets induced by “ordinal aggregation methods”. Such methods are interpreted here as performing paired comparisons of alternatives based on the “importance” of attributes favoring each element of the pair: alternative x will be preferred to alternative y if the attributes for which x is better than y are “more important” than the attribut...

Cet article cherche à voir si le sexe et la profession du conjoint peuvent expliquer l'ampleur et le type de soutien conjugal quand des personnes sont aux prises avec un stress important par rapport à leur travail. Pour ce faire nous analysons les données tirées d'une enquête auprès d'un échantillon d'avocates et d'avocats qui sont mariés pour certaines et certains à une personne exerçant la mê...

1. An in vitro analogue of long-term sensitization training was used to gain insights into the mechanisms and time course of the memory for long-term sensitization in Aplysia. The analogue, consisting of four blocks of shocks, was delivered to peripheral nerves of the isolated pleural-pedal ganglia, which contain the sensory neurons and motor neurons that mediate the tail withdrawal reflex. 2. ...

Agent-based modelers in the field of marketing research have paid little attention to validation issues. This paper provides a definition of validation relevant for this community of modelers. On the basis of a history-friendly model for simulation calibration [Malerba, F., Nelson, R., Orsenigo, L., and Winter, S. (1999). ‘History-friendly’ models of industry evolution: the computer industry. I...

AIM The course of heart failure (HF) is characterized by frequent hospitalizations, a high mortality rate, as well as a severely impaired health-related quality of life (HRQoL). To optimize disease management, understanding of patient preferences is crucial. We aimed to assess patient preferences using conjoint methodology and HRQoL in patients with HF. METHODS Two modules were applied: an in...

The foundational model of conjoint analysis is to model consumer purchase preferences by means of utility functions. Analysts run surveys and interviews to obtain a basic set of training data, typically user preferences on which the utility function is mapped. The utility theory trust the training data as knowledge while there is large literature emphasizing that users preference may change, ma...

Innovation management focuses too much on processes and tools, whereas entrepreneurship is pre-occupied with individual personal traits. However, many of the most successful innovations were co-created by multiple entrepreneurs, and it is this interaction of talent that is at the core of radical innovation, what we call Conjoint Innovation. We examine 15 cases, historical and contemporary, to i...
