Since people often communicate internal states and intentions through movement, robots can better interact with humans if they too can modify their movements to communicate changing state. These movements, which may be seen as supplementary to those required for workspace tasks, may be termed “expressive.” However, robot hardware, which cannot recreate the same range of dynamics as human limbs, often limit expressive capacity. One solution is to augment expressive robotic movement with expressive sound. To that end, this paper presents an application for synthesizing sounds that match various movement qualities. Its design is based on an empirical study analyzing sound and movement qualities, where movement qualities are parametrized according to Laban’s Effort System. Our results suggests a number of correspondences between movement qualities and sound qualities. These correspondences are presented here and discussed within the context of designing movement-quality-to-sound-quality mappings in our sound synthesis application. This application will be used in future work testing user perceptions of expressive movements with synchronous sounds.

Semantic Metrics

Fault tolerance techniques are generally based around a common concept that is redundancy whose measurement is required. A suite of four semantic metrics is proposed to assess program redundancy and reflect their ability to tolerate faults. Literature shows that one of these metrics, namely state redundancy, is limited to compute program redundancy only in their initial and final states and ignores their internal states. Consequently, the authors focus in this paper to overcome this shortcoming by proposing a new redundancy-based semantic metric that computes the redundancy of the different program states including internal ones. The empirical study they perform shows that the proposed metric is a measure of program redundancy in one side and is an error detection indicator in another side. Moreover, they demonstrate that it is more accurate than the basic state redundancy metric in detecting masked errors. It is useful for testers to indicate if a tested program is error-free and to pinpoint the presence of masked errors even if the final states are equal to the expected ones.

Information Technology (IT) projects have high failure and escalation rates because of the nature of domain and the rapid technology changes. It is important to understand the factors causing IT project success or failure. This chapter reviews the literature related to project failure and escalation and concludes with 17 important factors that cause IT projects to fail and 10 factors that contribute to the escalation of projects in time, cost, or scope. The concluded factors are utilized in an empirical study to explore the Jordanian environment and check the rank of these factors as perceived by Jordanian specialists. Conclusions and future work are stated at the end of this chapter.

Adaptive Interaction

AbstractCommunicative interactions across different species have so far received relatively little attention from cognitive or behavioral scientists. Most research in this area views the process of communication as the adaptive interaction of manipulative signalers and information-assessing receivers. This paper discusses some shortcomings of the information/influence model of communication, particularly in the empirical study of interspecific communicative interactions. It then presents an alternative theoretical model, based on recent contributions in psycholinguistics and semiotics. The semiotic alignment model views communication as a dynamic process of joint semiosis resulting in the alignment of the interactants’ own-worlds (Umwelten). It is argued that this model can improve our understanding of communicative interactions between heterospecifics and provide the basis for future work in the empirical study of interspecific communication.

Ranking implemented in the English for Academic Purposes course helps in selecting appropriate sub-topics to be obtained by students. The aim of the present research is to compare teacher’s and students’ ranking of topics of the English for Academic Purposes course delivered to master of engineering students underpinning the elaboration of implications for the advancement of the English for Academic Purposes course. Research methods applied include the use of theoretical as well as empirical methods. Theoretical methods imply analysis of theoretical sources and theoretical modelling. The empirical study was characterized by its explorative nature. The empirical study was based on a survey carried out with 10 engineering master students of the Master programme “Information and Electrical Engineering” at Hochschule Wismar, Germany. The data were interpreted and summarized. The summarizing content analysis allows proposing that the students positively evaluated the majority of the sub-topics of the delivered English for Academic Purposes course. The hypothesis was formulated. Implications for the advancement of the English for Academic Purposes course were identified. Directions of future work were proposed. The novelty of the research is revealed by the formulated hypothesis as well as implications

This research study investigates the potential to apply a quality analysis process for mobile learning (M-learning) software applications in accordance to a defined set of information quality characteristics in attempt to increase the level of quality in the mobile learning systems. This empirical study is conducted on widely accepted and used M-learning application form both close source and open source systems comprising a known reasonable amount of MLOC, medium-scale. Four M-learning applications were selected for conducting this study including Moodle, Blackboard, Edmodo and Schoology. The systems are statically analyzed and examined to determine if it meets the proposed quality characteristics or not. For each system the features and techniques used with respect to the defined characteristics are determined and tabulated. This study focuses mainly on particular information quality characteristics include maintainability, reusability, testability, and security. The data shows that the approach is applicable and effective but needs further formalization and improvement to be effectively implemented. New ideas are additionally proposed for future work to include other dimensions of the M-learning application quality characteristics such as availability, reliability, performance, usability, and functionality. This empirical study is part of funded research project investigating the development, adoption and dissemination of M-learning in Oman.
