Collaborative Activities

Collaborative systems support shared spaces, where groups of users exchange interactions. In order to ensure the usability of these systems, an intuitive interactions’ organization and that each user has awareness information to know the activity of others are necessary. Usability laboratories allow evaluators to verify these requirements. However, laboratory usability evaluations can be problematic for reproducing mobile and ubiquitous contexts, as they restrict the place and time in which the user interacts with the system. This paper presents a framework for building software support that it collects human–machine interactions in mobile and ubiquitous contexts and outputs an assessment of the system’s usability. This framework is constructed through learning that is based on neural networks, identifying sequences of interactions related to usability problems when users carry out collaborative activities. The paper includes a case study that puts the framework into action during the development process of a smartphone application that supports collaborative sport betting.

Emergent Behaviors

The sooner disruptive emergent behaviors are detected, the sooner preventive measures can be taken to ensure the resilience of business processes execution. Therefore, organizations need to prepare for emergent behaviors by embedding corrective control mechanisms, which help coordinate organization-wide behavior (and goals) with the behavior of local autonomous entities. Ongoing technological advances, brought by the Industry 4.0 and cyber-physical systems of systems paradigms, can support integration within complex enterprises, such as supply chains. In this paper, we propose a reference enterprise architecture for the detection and monitoring of emergent behaviors in enterprises. We focus on addressing the need for an adequate reaction to disruptions. Based on a systematic review of the literature on the topic of current architectural designs for understanding emergent behaviors, we distill architectural requirements. Our architecture is a hybrid as it combines distributed autonomous business logic (expressed in terms of simple business rules) and some central control mechanisms. We exemplify the instantiation and use of this architecture by means of a proof-of-concept implementation, using a multimodal logistics case study. The obtained results provide a basis for achieving supply chain resilience “by design”, i.e., through the design of coordination mechanisms that are well equipped to absorb and compensate for the effects of emergent disruptive behaviors.

Education Courses

Targeting at students randomly selected across all departments and all years at one university located in northern Taiwan, this research based on hierarchical regression analysis aims to investigate whether or not global warming awareness education exerts a positive effect on research participants’ energy-saving cognition and attitude. the results indicate that the 8 hypotheses proposed are all supported. Firstly, green education courses and global warming awareness videos have significantly positive impact on participants’ cognition and attitude as compare to their peers who did not take the courses or view the videos. Secondly, the participants’ scientific literacy positively influences their energy-saving cognition, which in turn positively impacts on energy-saving attitude. Furthermore, energy-saving cognition plays a completely intermediate role between scientific literacy and energy-saving attitude. Results mentioned conclude the contributions of this research.

Quantitative Case Study

<p>Achieving a near-native speaker’s pronunciation is so essential for EFL learners. However, many factors contribute to the challenges faced by EFL learners, mainly due to the difference in the sound system of English Language and that of their first language. For this reason, Arab learners of English Language may mispronounce some English sounds. This paper analyzed one of the few problematic sounds to the Arab Yemeni EFL learners - the pronunciation of the English voiceless postalveolar affricate /ʧ/. The study which has a quantitative case study design uses four Yemeni EFL postgraduate students as its participants. The participants’ pronunciations of /tʃ/ sound in the initial, middle and final word-positions were analyzed using Praat phonetic software. The findings of the study showed that Yemeni EFL learners have difficulties in producing the /tʃ/ sound, especially in the initial and final positions, and deaffrication of /tʃ/  occurred in the  pronunciation of the four participants. The current study is expected to be of value, particularly for EFL learners, teachers, as well as material writers.</p><p> </p>

Quantitative Case Study

AbstractThe welfare state literature argues that Social Democratic party representation is of key importance for welfare state outcomes. However, few papers are able to separate the influence of parties from voter preferences, which implies that the partisan effects will be overstated. I study a natural experiment to identify a partisan effect. In 1995, the Labour Party (Ap) in the Norwegian municipality of Flå filed their candidate list too late and could not participate in the local election. Ap was the largest party in Flå in the entire post-World War period, but have not regained this position. I use the synthetic control method to study the effects on welfare spending priorities. I find small and insignificant partisan effects.
