A key challenge in the representation of qualitative, multi-criteria preferences is to find a compact and expressive representation. Various frameworks have been introduced, each of which with its own distinguishing features. In this paper we introduce a new representation framework called qualitative preference systems (QPS), which combines priority, cardinality and conditional preferences. Mo...

A numerical approach is classically advocated (see e.g. [12]) for encoding both the information pertaining to the state of nature and the preferences on X: uncertainty is represented by a probability distribution p and preference is encoded by a utility function u : X → [0, 1] . The pair < p, u > will be called a probabilistic utility model, PU-model for short. Acts are then ranked according to...

This work studies how goal-directed agents can form profitable coalitions. A coalition is formed when some agents agree to cooperate for the achievement of a shared goal or to exchange with each other the achievement of their own goals. Assuming that coalition formation processes are supported by unanimous and enforced agreements, we define two qualitative criteria: the do-ut-des property and t...

While the evaluation of quantitative research frequently depends on judgements based on the “holy trinity” of objectivity, reliability and validity (Spencer, Ritchie, Lewis, & Dillon, 2003, p. 59), applying these traditional criteria to qualitative research is not always a “good fit” (Schofield, 2002). Instead, educational researchers who engage in qualitative research have s...

For many cases, grading and prioritizing the projects are so important in project-based organizations. In fact, it means prioritizing some projects and allocating organizational resource only to those projects to reach the organization profit up to maximum level through such allocation and decision. There are many different factors contribute in choosing the best project combination for organiz...

Abstract This review aims to synthesize a published set of evaluative criteria for good qualitative research. The aim is shed light on existing standards assessing the rigor research encompassing range epistemological and ontological standpoints. Using systematic search strategy, journal articles that deliberate rigorous were identified. Then, references relevant surveyed find noteworthy, disti...

This research set out to find out the mate selection criteria among single female teachers. This qualitative study was carried out via thematic analysis approach. Using purposive sampling method, 15 single female teachers aged 18 to 30 years old were identified in Tehran and fifteen semi-structured interviews were conducted. The interviews were recorded, transcribed and then were analyzed using...

Much contemporary dialogue has centered on the difficulty of establishing validity criteria in qualitative research. Developing validity standards in qualitative research is challenging because of the necessity to incorporate rigor and subjectivity as well as creativity into the scientific process. This article explores the extant issues related to the science and art of qualitative research an...
