- Purpose – The purpose of this paper is twofold: first, to empirically test whether a “one size fits all” strategy fits the fashion e-commerce business and second, to evaluate whether consumer returns are a central aspect of the creation of profitability and, if so, to discuss the role of returns management (RM) in the supply chain strategy. Design/methodology/approach – Transactional sales and return data were analysed and used to categorise customers based on their buying and returning behaviours, measuring each customer's net contribution margins. Findings – The e-commerce business collects a vast quantity of data, but these data are seldom used for the development of service differentiation. This study analysed behaviour patterns and determined that the segmentation of customers on the basis of both sales and return patterns can facilitate a differentiated service delivery approach. Research limitations/implications – This research empirically supports the theory that customer buying and returning behaviours can be used to appropriately categorise customers and thereby guide the development of a more differentiated service approach. Practical implications – The findings support a differentiated service delivery system that utilises a more dynamic approach, conserving resources and linking the supply chain and/or organisational strategies with customers' buying and returning behaviours to avoid over and underservicing customers. Originality/value – Consumer returns are often viewed as a negative aspect of doing business; interestingly, however, the authors revealed that the most profitable customer is a repeat customer who frequently returns goods.

- Abstract: Likert-type data are often assumed to be equidistant by applied researchers so that they can use parametric methods to analyse the data. Since the equidistance assumption rarely is tested, the validity of parametric analyses of Likert-type data is often unclear. This paper consists of two parts where we deal with this validity problem in two different respects. In the first part, we use an experimental design to show that the perceived distance between scale points on a regular five-point Likert-type scale depends on how the verbal anchors are used. Anchors only at the end points create a relatively larger perceived distance between points near the ends of the scale than in the middle (end-of-scale effect), while anchors at all points create a larger perceived distance between points in the middle of the scale (middle-of-scale effect). Hence, Likert-type scales are generally not perceived as equidistant by subjects. In the second part of the paper, we use Monte Carlo simulations to explore how parametric methods commonly used to compare means between several groups perform in terms of actual significance and power when data are assumed to be equidistant even though they are not. The results show that the preferred statistical method to analyse Likert-type data depends on the nature of their nonequidistance as well as their skewness. Under middle-of-scale effect, the omnibus one-way ANOVA works best when data are relatively symmetric. However, the Kruskal-Wallis test works better when data are skewed except when sample sizes are unequal, in which case the Brown-Forsythe test is better. Under end-of-scale effect, on the other hand, the Kruskal- Wallis test should be preferred in most cases when data are at most moderately skewed. When data are heavily skewed, ANOVA works best unless when sample sizes are unequal, in which case the Brown-Forsythe test should be preferred.

- Background: It is well established that parents must interact with their new-born babies to facilitate attachment. However, very little is known about how parents perceive different types of medical technology products commonly used in the neonatal intensive care unit (NICU) as barriers to their wish to interact with their infants. Aim: This study aims to examine to what extent the different medical technology products commonly used in the NICU are perceived by parents to be obstacles in their wish to interact with their babies. Design and methods: In 2010, a cross-sectional survey, using a questionnaire specifically developed for this study, was conducted among the parents of children who were discharged from any of the five NICUs of the Vastra Gotaland region in Sweden. A consecutive sample of 248 parents anticipated, and multiple regressions and t-tests were used to analyse the data. Results: The parents generally perceived the various medical technology products differently, according to the perceived level of obstruction. The variables of gender, age,educational level, origin, gestational age, previous experience of being a parent, and the offer of accommodation at the NICU were significantly associated with the perceived level of obstruction in the parents’ wish to interact with their baby while the baby was being treated with different medical technology products. Conclusion: The primary implication for practice is that to facilitate attachment, nurses should involve different categories of parents in different ways in the care of their children, depending on the equipment being used in the treatment of the children. Thus, the individual care plan should explicitly include the details of the specific medical equipment, because although its use is medically beneficial for the child, it is associated with potential liabilities regarding parent–child interaction and, consequently, regarding parent–child attachment.
