Some consumer preference studies show that red is the most popular flower color. Most data analyses were univariate. Conjoint analysis allows simultaneous determination of attribute preferences without all alternatives being shown. Our purpose was to determine consumer preferences for geranium flower color, leaf variegation, and price simultaneously using conjoint analysis. Two-hundred and four consumers shopping at two Montgomery, Ala., garden centers in Apr. 1993 rated 25 composite geranium photographs. A lavender geranium, `Danielle', with green and white leaf variegation priced at $1.39 was most preferred. Flower color was most important in the purchase decision, followed by price. Leaf variegation was a minor consideration in the purchase decision.

Vegetable oils contain various antioxidants, including vitamin E and unsaturated fatty acids. Some of these oils, especially olive oil, contain another group of antioxidant – phenolic compounds. The health benefits from the phenolics have recently been published with the rising recommendation of communicating these effects on food labels. As an official testing method is unavailable from AOCS and AOAC, we developed an HPLC method based on the biophenol method of the International Olive Council. Many analytical standards are commercially unavailable for biophenols, and neither retention time nor capacity factor can be used in chromatograms for biophenol identification. Therefore we identified a set of available standards with different retention times to spread across the chromatogram in addition to an internal standard. The biophenol profile can thus be established referring to these standards. More than 20 biophenols were included in this method. Different brands of olive oil and several types of vegetable oils were sampled and tested. Extra virgin olive oil was found to have the highest content while fewer biophenols were found in processed olive oil and other vegetable oils. As for the other vegetable oils different biophenol profiles were also observed. This method has great potential in olive oil authenticity testing, and in quality control to differentiate substandard olive oils.

Identifying user preferences is a very important activity before offering a suggestion or a product. E-learning systems also follow suit in identifying the user preferences of learning style before offering the e-learning contents. There are several methods discussed in the literature for identifying the user preferences for e-learning contents. This paper presents a new method for the same purpose. The core of the new method is Conjoint Analysis, which is based on the type of the contents, preferred volume for each type of content and the ranking for the various combinations of the contents and their preferred volumes. The outcome of this method is the most preferred learning style of an individual learner.

Customers’ needs and wants with regard to dairy products are increasingly diverse, and companies must be able to produce a variety of products. This study aimed to obtain alternative product configurations in accordance with customer requirements and to determine the types of modules required to realize the product by synergizing conjoint analysis and the decision-making trial and evaluation laboratory (DEMATEL) method. The product configuration was based on pleasurable design consisting of three aspects, namely functionality, usability, and pleasure. Pleasurable design was chosen because it involves the human in the product design as a product user so that the product design is in accordance with customer expectations. The research used the survey method with consumers of ice cream. Descriptive analysis was used to describe the product attributes desired by consumers. Orthogonal design was used to construct alternative product configurations, while the product configuration rank was determined using conjoint analysis. Based on the results of the research, the selected attributes for the functionality aspects were taste and texture, the selected attributes for the usability aspects were shape and packaging materials, and the selected attributes for the pleasure aspects were health benefits and appearance. The orthogonal design results led to 25 alternative product configurations, followed by determination of the ranking of alternative product configurations. Then the DEMATEL method was applied to analyse the relationship between the product configuration attributes to determine the types of modules that must be provided.

This paper summarises the results of an investigation of willingness to pay (WTP) for new vaccines. The vaccines considered are for infections with several subtypes. One option is to cover a broad combination of these within one vaccine although this is associated with additional development complexities. The associated durations of effect of such vaccines are not yet known; therefore the impact of variations in this and the subtype coverage, as well as that of opting for a non-reimbursement status, were among the issues that needed to be assessed. One important group for a determination of WTP is parents, in that they could be paying for vaccination of themselves and/or their children. This paper reports the findings of WTP among this group for their children for alternative outcomes in the vaccine product profile. For reasons of confidentiality, results from only this group in the context of paying for their children are reported. The exact wording of the product features tested have also been changed for the same reason.
