This chapter presents issues that may arise in human-centered research in health care environments. The authors first discuss why human-centered approach is increasingly employed to study and to design health care technology. They then present some practical concerns that may arise when conducting qualitative research in medical settings, from research design, to data collection and data analysis, and to technology design. Many of these concerns were also experienced in their own human-centered field studies conducted in the last few years. The authors conclude the chapter by illustrating some of these issues using their own research case study that investigated nurses’ information flow in a hospital ward.

With the advancement of web services technology, security has become an increasingly important issue. Various security standards have been developed to secure web services at the transport and message level, but application level has received less attention. The security solutions at the application level focus on access control which cannot alone ensure the confidentiality and integrity of information. The solution proposed in this paper consists on a hybrid model that combines access control (AC) and information flow control (IFC). The AC mechanism uses the concept of roles and attributes to control user access to web services' methods. The IFC mechanism uses labels to control how the roles access to the system's objects and verify the information flows between them to ensure the information confidentiality and integrity. This manuscript describes the model, gives the demonstration of the IFC model safety, presents the modeling and implementation of the model and a case study.

Schedule analysts often resolve diverse schedule delay problems in construction projects based on their subjective experiences. Although various process-based and mathematical-model schedule delay analysis methods are available for effective schedule delay analysis, these methods require time-consuming manual operation. The use of computer-based schedule delay analysis methods seems to be a solution. However, schedule analysts still have difficulty developing computer-based schedule delay analysis methods. Therefore, this study applies information flow analysis to classify the necessary work to develop computer-based schedule delay analysis methods. In contrast to numerous studies that focus only on computerizing a process-based or a mathematical-model schedule delay analysis method, this study constructs a computer-based method that integrates two process-based schedule delay analysis methods simultaneously. In a tested case study, the delay liability for the project owner and contractor was classified successfully. Importantly, this study provides a useful reference for similar applications in project management.

The study is premised on speech and writing relying on differently coordinated temporal frames of communication, aiming to pinpoint the conceptual and linguistic differences between spoken and written Hebrew narration. This is a case study presenting in-depth psycholinguistic analyses of the oral and written versions of a personal-experience story produced by the same adult narrator in Hebrew, taking into account discursive functions, discourse stance, linguistic expression, and information flow, processing, and cohesion. Findings of parallel spoken and written content units presenting the same narrative information point to the interface of the narrative genre with the spoken and written modalities, together with the mature cognitive, linguistic, and social skills and experience of adulthood. Both spoken and written personal-experience adult narrative versions have a non-personal, non-specific, detached stance, though the written units are more abstract and syntactically complex. Adult narrating skill encompasses both modalities, recruiting different devices for the expression of cohesion.

Three integrity measures are introduced: contamination, channel suppression and program suppression. Contamination is a measure of how much untrusted information reaches trusted outputs; it is the dual of leakage, which is a measure of information-flow confidentiality. Channel suppression is a measure of how much information about inputs to a noisy channel is missing from the channel outputs. And program suppression is a measure of how much information about the correct output of a program is lost because of attacker influence and implementation errors. Program and channel suppression do not have interesting confidentiality duals. As a case study, a quantitative relationship between integrity, confidentiality and database privacy is examined.

Abstract. We investigate the use of landslide failure forecast models by exploiting near-real-time monitoring data. Starting from the inverse velocity theory, we analyze landslide surface displacements on different temporal windows, and apply straightforward statistical methods to obtain confidence intervals on the estimated time of failure. Here we describe the main concepts of our method, and show an example of application to a real emergency scenario, the La Saxe rockslide, Aosta Valley region, northern Italy. Based on the herein presented case study, we identify operational thresholds based on the reliability of the forecast models, in order to support the management of early warning systems in the most critical phases of the landslide emergency.

This research analyzes the informational flow of the Customer Service Channels of the Brazilian Post Office and Telegraph Company, Regional Board of Directors of Paraíba, under the perspective of information management, questioning how the information of such flow has influence on the formulation of tactical actions for decision-making. With regard to the objectives, the methodology is classified as descriptive with qualitative approach of the case study type. For data collection, the research used the guided interview and documental analysis categorizing the information according to the content analysis for interpreting them. As result, the research found that every action, in a corporate level, occurs in a standardized manner, inclusive in reference to solution and response proposed to customers. Therefore, it can be concluded that the information flow of the Customer Service Channels, if treated in a systematic manner, is a useful tool for qualitative diagnosis of the offered services so as to identify the client’s need as well as to add value to the company, by improving its image and, finally to the local society.
