Brand price differentials in retail distribution: product quality and service quality
2016
ABSTRACTA theoretical model is proposed to disentangle the contribution of brand quality and retailer service quality in explaining brand price differentials across retailers. Two testable hypotheses emerge: (i) for each brand type, price differences across retailers are independent of brand quality differentials and (ii) at a given retailer, price differences between different brand qualities are independent of service quality differentials. Our empirical analysis, for a sample of the U.K. grocery retailer prices, discloses that retailers that offer higher service quality sell same quality brands at higher prices. In particular, service quality premia amount to 6% for national brands and a…
Unawareness and bankruptcy: A general equilibrium model
1998
International audience; We present a consistent pure-exchange general equilibrium model where agents may not be able to foresee all possible future contingencies. In this context, even with nominal assets and complete asset markets, an equilibrium may not exist without appropriate assumptions. Specific examples are provided. An existence result is proved under the main assumption that there are sufficiently many states that all the agents foresee. An intrinsic feature of the model is bankruptcy, which agents may involuntarily experience in the unforeseen states.
Consumer Awareness and the Use of Payment Media: Evidence from Young Finnish Consumers
2008
In the market for payment media, some consumers use only one medium when paying for their point-of-sale transactions, while others use many. This pattern reflects the diffusion of new payment media, because a payment method innovation is typically first used simultaneously with the established methods. We study the use of multiple payment media by employing data on young Finnish consumers. We find that the use of multiple payment media is directly related to consumer awareness and that not controlling for the endogeneity of awareness can bias its effect downwards. These results suggest that increasing consumer awareness may have been underlying the rise of debit card use around the world. I…
Psychometric properties of the emotional awareness questionnaire in a Spanish child population
2016
La competencia emocional es la capacidad para percibir, expresar, comprender, regular y controlar nuestras emociones y las de los demás. La conciencia emocional es la competencia básica que permite el desarrollo del resto de competencias emocionales durante la infancia y la adolescencia. En este trabajo, se han estudiado las propiedades psicométricas de la versión española del Cuestionario de conciencia emocional, administrado a 1476 niños/as españoles (8-12 años). Se ha replicado la estructura original formada por seis factores. Se han estudiado la Habilidad de los ítems y del instrumento, la validez de constructo, de contenido y concurrente, los resultados han sido satisfactorios. Se han …
Classroom interaction and literacy activities in kindergarten : Longitudinal links to grade 1 readers at risk and not at risk of reading difficulties
2017
The purpose of the present study is to establish how the quality of kindergarten classroom interactions and the frequency of literacy activities affect reading development among Grade 1 children—both those who are at risk and not at risk of developing reading difficulties. Interaction was assessed in terms of classroom organization, and the level of emotional and instructional support offered in 49 kindergarten classrooms in Finland using the CLASS (Classroom Assessment Scoring System). Kindergarten teachers also recorded the frequency of literacy activities in their classrooms. The phonological awareness and letter knowledge of 515 children (i.e., their pre-reading skills) were assessed at…
The Impacts of ICT Support on Information Distribution, Task Assignment for Gaining Teams’ Situational Awareness in Search and Rescue Operations
2015
Information and Communication Technology (ICT) has changed the way we communicate and work. To study the effects of ICT for Information Distribution (ID) and Task Assignment (TA) for gaining Teams’ Situational Awareness (TSA) across and within rescue teams, an indoor fire game was played with students. We used two settings (smartphone-enabled support vs. traditional walkietalkies) to analyze the impact of technology on ID and TA for gaining TSA in a simulated Search and Rescue operation. The results presented in this paper combine observations and quantitative data from a survey conducted after the game. The results indicate that the use of the ICT was good in second scenario than first sce…
Experiencing Urban Mining in an Italian Municipality towards a Circular Economy vision
2017
Abstract Selective waste collection in Italy has undergone significant changes over the last decade, highlighting very different approaches from one region to another. Research results presented in this paper are underlying differences between geographical regions and use them as a model of good practices to improve the less optimized systems. In the last decade, the Trento City Council has established a goal – the optimization of selective municipal solid waste collection – that led to a very low amount of recyclable materials in the residual fraction. More than that, for the first time sanitary textiles have been considered as a separable fraction at the source; for a long time this type …
Enabling independent navigation for visually impaired people through a wearable vision-based feedback system
2017
This work introduces a wearable system to provide situational awareness for blind and visually impaired people. The system includes a camera, an embedded computer and a haptic device to provide feedback when an obstacle is detected. The system uses techniques from computer vision and motion planning to (1) identify walkable space; (2) plan step-by-step a safe motion trajectory in the space, and (3) recognize and locate certain types of objects, for example the location of an empty chair. These descriptions are communicated to the person wearing the device through vibrations. We present results from user studies with low- and high-level tasks, including walking through a maze without collisi…
Identifying First Responders Information Needs
2016
At the onset of an indoor fire emergency, the availability of the information becomes critical due to the chaotic situation at the emergency site. Moreover, if information is lacking, not shared, or responders are too overloaded to acknowledge it, lives can be lost and property can be harmed. Therefore, the goal of this paper is to identify information items that are needed for first responders during search and rescue operations. The authors use an educational building fire emergency as a case and show how first responders can be supported by getting access to information that are stored in different information systems. The research methodology used was a combination of literature review,…
Ubiquitous Co-Driver System and Its Effects on the Situation Awareness of the Driver
2008
The aim of this paper is to explore the effects of ubiquitous computing in cars on the situation awareness and expectations of the driver. In a driving simulation environment with participants using a co-driver system, we investigated how people took and recovered from misinformation provided by the system. The system presented safety-critical information about the upcoming curves on the road, but in the experiment part of the messages contained false information. The effects of this information on participants’ behavior were investigated. On the grounds of the experiment, we discuss two approaches for investigating drivers’ situational awareness, which are based on either mental workload o…
