The concept of a consideration set has become a central concept in the study of consumer behavior. This paper shows that the common practice of estimating models using only the set of alternatives deemed to be in the set considered by a consumer will usually result in estimated parameters that are biased due to a sample selection effect. This effect is generic to many consideration set models a...

The use of the pulse oximeter to estimate oxygen saturation has revolutionized monitoring capabilities in medicine. However, there can be circumstances in which there is a discordance between oxygen saturation measurements via pulse oximeter (SpO2) and actual arterial oxygen levels (PaO2). In these situations, there is a possibility the patient could have a variant hemoglobin as the etiology of...

The authors present an approach to classify a brand’s buyers into groups with varying degrees of loyalty along a continuum from “hard-core loyal” to “hard-core switcher.” A classification scheme is developed based on the joint use of stated consideration set and brand switching data. The resulting loyalty taxonomy yields five mutually exclusive segments: Hard-Core Loyal (HCL), Soft Loyal (SL), ...

In practice based research, especially when working with non-research organisations, sometimes researchers face challenges related to the willingness of participants to openly share experiences outside the realms of the project. As a consequence there are methodological challenges with showing results, and working with knowledge verification. In this paper we suggest that some of these obstacle...

Minimally invasive surgical procedures aim to minimize the tissue trauma but still achieve a satisfactory therapeutic result. Tissue trauma is significantly less than conventional open procedure. Laparoscopy is the process of inspecting the abdominal cavity through an endoscope. Carbon dioxide is commonly used to insufflate the abdominal cavity to facilitate the view. The surgical advantages of...

Autoimmune haemolytic anaemia may occur during the course of influenza A infection2 and if this occurs it may pose a major problem for people with thalassaemia. In France, annual influenza vaccination is recommended and free of charge for children with chronic disease, including thalassaemia.3 In countries where thalassaemia is endemic, such as Thailand, it is also recommended that all people w...
