The Impact of Cultural Familiarity on Studentsâ Social Media Usage in Higher Education
Using social media (SM) in Higher education (HE) becomes unavoidable in the new teaching and learning pedagogy.
The current generation of students creates their groups on SM for collaboration. However, SM can be a primary source of
learning distraction due to its nature, which does not support structured learning. Hence, derived from the literature, this study proposes three learning customised system features, to be implemented on SM when used in Higher Education HE.
Nevertheless, some psychological factors appear to have a stronger impact on studentsâ adoption of SM in learning than the proposed features. A Quantitative survey was conducted at a university in Uzbekistan to collect 52 undergraduate studentsâ perception of proposed SM learning customised features in Moodle. These features aim to provide localised, personalised, and privacy control self-management environment for collaboration in Moodle. These features could be significant in predicting studentsâ engagement with SM in HE. The data analysis showed a majority of positive feedback towards the proposed learning customised SM. However, the surveyed studentsâ engagement with these features was observed as minimal. The course leader initiated a semi-structured interview to investigate the reason. Although the students confirmed their acceptance of the learning customised features, their preferences to alternate SM, which is Telegram overridden their usage of the proposed learning customized SM, which is Twitter. The students avoided the Moodle integrated Twitter (which provided highly accepted features) and chose to use the Telegram as an external collaboration platform driven by their familiarity and social preferences with the Telegram since it is the popular SM in Uzbekistan. This study is part of an ongoing PhD research which involves deeper frame of learnersâ cognitive usage of the learning management system. However, this paper exclusively discusses the cultural familiarity impact of studentâs adoption of SM in HE
Methodological Guide to Co-design Climate-smart Options with Family Farmers
Climate-smart agriculture (CSA) seeks to improve productivity for the achievement of food
security (pillar 1: Productivity), to develop a better ability to adapt (pillar 2: Adaptation), and
to limit greenhouse gas emissions (pillar 3: Mitigation). Technical and organizational
innovations are needed to find synergies among those three pillars.
Innovation (its creation and its operation) is a social phenomenon. Many studies worldwide
have shown that promoting a sustainable change and innovation within organizations has to
be analyzed and implemented with stakeholders. Thus, the ability of local actors to tackle
climate change and mitigate its effects will depend on their ability to innovate and mobilize
material and non-material resources, to articulate links among national policies, not only
between themselves, but also undertaking actions at the local level. To support stakeholders
in the development of responses to this challenge, we propose the development of open
innovation platforms, in which all local actors may participate. These platforms are virtual,
physical, or physico-virtual spaces to learn, jointly conceive, and transform different
situations; they are generated by individuals with different origins, different backgrounds and
interests (Pali and Swaans, 2013).The purpose of this manual is to provide a seven-step methodology to allow family farmers to co-build and adopt CSA options to tackle climate change in an open innovation platfor
Design Criteria to Architect Continuous Experimentation for Self-Driving Vehicles
The software powering today's vehicles surpasses mechatronics as the
dominating engineering challenge due to its fast evolving and innovative
nature. In addition, the software and system architecture for upcoming vehicles
with automated driving functionality is already processing ~750MB/s -
corresponding to over 180 simultaneous 4K-video streams from popular
video-on-demand services. Hence, self-driving cars will run so much software to
resemble "small data centers on wheels" rather than just transportation
vehicles. Continuous Integration, Deployment, and Experimentation have been
successfully adopted for software-only products as enabling methodology for
feedback-based software development. For example, a popular search engine
conducts ~250 experiments each day to improve the software based on its users'
behavior. This work investigates design criteria for the software architecture
and the corresponding software development and deployment process for complex
cyber-physical systems, with the goal of enabling Continuous Experimentation as
a way to achieve continuous software evolution. Our research involved reviewing
related literature on the topic to extract relevant design requirements. The
study is concluded by describing the software development and deployment
process and software architecture adopted by our self-driving vehicle
laboratory, both based on the extracted criteria.Comment: Copyright 2017 IEEE. Paper submitted and accepted at the 2017 IEEE

EFL pedagogy students' self-directed learning: use of edmodo and e-portfolio
Tesis (PedagogĂa en InglĂ©s)This study aims at exploring how Edmodo and E-Portfolio affect EFL Pedagogy Studentsâ Self-Directed Learning (SDL). The theory is framed within the concepts of Self-Directed Learning and online platforms. This mixed type of research (qualitative and quantitative) considered 3 different instruments to collect data: questionnaires (PRO-SDLS), interviews, and a focus group. The participants were 26 freshmen in an English Pedagogy program. From the data obtained and analyzed, the study showed that there is a statistically significant difference in the participantsâ SDL between the pre and posttest. At the same time, students perceived that E-Portfolio is more useful than Edmodo in their learning process.Este estudio tiene como objetivo explorar cĂłmo Edmodo e E-Portfolio afectan en el aprendizaje autodirigido en estudiantes que aspiran a ser profesores de EFL.

Adopting building information modeling (BIM) as collaboration platform in the design industry
This paper discusses the preliminary findings of an ongoing research project aimed at developing a technological, operational and strategic analysis of adopting BIM in AEC/FM (Architecture-Engineering-Construction/Facility Management) industry as a collaboration tool. Outcomes of the project will provide specifications and guidelines as well as establish industry standards for implementing BIM in practice. This research primarily focuses on BIM model servers as a collaboration platform, and hence the guidelines are aimed at enhancing collaboration capabilities. This paper reports on the findings from: (1) a critical review of latest BIM literature and commercial applications, and (2) workshops with focus groups on changing work-practice, role of technology, current perception and expectations of BIM. Layout for case studies being undertaken is presented. These findings provide a base to develop comprehensive software specifications and national guidelines for BIM with particular emphasis on BIM model servers as collaboration platforms
A new model-free design for vehicle control and its validation through an advanced simulation platform
A new model-free setting and the corresponding "intelligent" P and PD
controllers are employed for the longitudinal and lateral motions of a vehicle.
This new approach has been developed and used in order to ensure simultaneously
a best profile tracking for the longitudinal and lateral behaviors. The
longitudinal speed and the derivative of the lateral deviation, on one hand,
the driving/braking torque and the steering angle, on the other hand, are
respectively the output and the input variables. Let us emphasize that a "good"
mathematical modeling, which is quite difficult, if not impossible to obtain,
is not needed for such a design. An important part of this publication is
focused on the presentation of simulation results with actual and virtual data.
The actual data, used in Matlab as reference trajectories, have been obtained
from a properly instrumented car (Peugeot 406). Other virtual sets of data have
been generated through the interconnected platform SiVIC/RTMaps. It is a
dedicated virtual simulation platform for prototyping and validation of
advanced driving assistance systems. Keywords- Longitudinal and lateral vehicle
control, model-free control, intelligent P controller (i-P controller),
algebraic estimation, ADAS (Advanced Driving Assistance Systems).Comment: in 14th European Control Conference, Jul 2015, Linz, Austria. 201
A mechatronic approach to supernormal auditory localisation
Remote audio perception is a fundamental requirement for telepresence and teleoperation in applications that range from work in hostile environments to security and entertainment. The following paper presents the use of a mechatronic system to test the efficacy of audio for telepresence. It describes work to determine whether the use of supernormal inter-aural distance is a valid means of approaching an enhanced method of hearing for telepresence. The particular audio variable investigated is the azimuth angle of error and the construction of a dedicated mechatronic test rig is reported and the results obtained. The paper concludes by observing that the combination of the mechatronic system and supernormal audition does enhance the ability to localise sound sources and that further work in this area is justified

Combining Exploratory Learning With Structured Practice to Foster Conceptual and Procedural Fractions Knowledge
Robust domain knowledge consists of conceptual and procedural knowledge. The two types of knowledge develop together, but are fostered by different learning tasks. Exploratory tasks enable students to manipulate representations and discover the underlying concepts. Structured tasks let students practice problem-solving procedures step-by-step. Educational technology has mostly relied on providing only either task type, with a majority of learning environments focusing on structured tasks. We investigated in two quasi-experimental studies with 8-10 years old students from UK (N = 121) and 10-12 years old students from Germany (N = 151) whether a combination of both task types fosters robust knowledge more than structured tasks alone. Results confirmed this hypothesis and indicate that students learning with a combination of tasks gained more conceptual knowledge and equal procedural knowledge compared to students learning with structured tasks only. The results illustrate the efficacy of combining both task types for fostering robust fractions knowledge
