The decoy effect is a well-known, intriguing decision-making bias that is often exploited by marketing practitioners to steer consumers towards a desired purchase outcome. It demonstrates that an inclusion of an alternative in the choice set can alter one’s preference among the other choices. Although this decoy effect has been universally observed in the real world and also studied by many economists and psychologists, little is known about how to mitigate the decoy effect and help consumers make informed decisions. In this study, we conducted two experiments: a quantitative experiment with crowdsourcing and a qualitative interview study—first, the crowdsourcing experiment to see if visual interfaces can help alleviate this cognitive bias. Four types of visualizations, one-sided bar chart, two-sided bar charts, scatterplots, and parallel-coordinate plots, were evaluated with four different types of scenarios. The results demonstrated that the two types of bar charts were effective in decreasing the decoy effect. Second, we conducted a semi-structured interview to gain a deeper understanding of the decision-making strategies while making a choice. We believe that the results have an implication on showing how visualizations can have an impact on the decision-making process in our everyday life.

The utilization of Decision Support Systems (DSS) in complex dynamic environments leads the human operator almost inevitably to having to face several types of uncertainties. Thus it is essential for system designers to clearly understand the different types of uncertainties that could exist in human-machine systems of complex environments, to know their impacts on the operator's trust in the systems and decision-making process, and to have guidelines on how to present uncertain information on user interfaces. It is also essential for them to have an overview of the different stages, levels, and types of system automation, and to know their possible impacts on the creation of different types of uncertainties. This paper investigates these topics and aim at helping researchers and practitioners to deal with uncertainties in complex environments.

AimTo explore parent and general practitioner (GP) understanding and beliefs about food allergy testing for children with eczema.Design and settingQualitative interview study in UK primary care within the Trial of Eczema allergy Screening Tests feasibility trial.ParticipantsSemi-structured interviews with parents of children with eczema taking part in the feasibility study and GPs at practices hosting the study.Results21 parents and 11 GPs were interviewed. Parents discussed a range of potential causes for eczema, including a role for food allergy. They believed allergy testing to be beneficial as it could potentially identify a cure or help reduce symptoms and they found negative tests reassuring, suggesting to them that no dietary changes were needed. GPs reported limited experience and uncertainty regarding food allergy in children with eczema. While some GPs believed referral for allergy testing could be appropriate, most were unclear about its utility. They thought it should be reserved for children with severe eczema or complex problems but wanted more information to advise parents and help guide decision making.ConclusionsParents’ motivations for allergy testing are driven by the desire to improve their child’s condition and exclude food allergy as a possible cause of symptoms. GPs are uncertain about the role of allergy testing and want more information about its usefulness to support parents and help inform decision making.Trial registration numberISRCTN15397185.

As higher education institutions strive to become increasingly international, English-medium teaching has become a main concern to develop students’ English proficiency in preparing them for international competition. Therefore, this study aims to investigate students’ perceptions and experience on a program called PEBUC. It is a program devised by the Faculty of Economy at Universitas Advent Indonesia (UNAI) in which the concept is derived from English Medium Instruction (EMI). It is a qualitative interview study, used to assess people’s experience, perceptions, behaviors and other aspects. Semi-structured interview was implemented to 10 informants who had experienced taking the program. The findings of this study showed two themes emerged on how students perceived the program; those themes are Promote Thinking-learning system and Stimulate Learners’ Engagement. Furthermore, there are two themes that characterize the experience of informants on the program; which are, Enhance recognition of English Language and Self-regulated learning. Meanwhile regarding the needs of program development there are two themes emerged: Learning Resources and Analysis on Students’ Prerequisites. All themes emerged from obtained sub-themes.
