Instant messaging an effective way of communication in workplace
The modern workplace is inherently collaborative, and this collaboration
relies on effective communication among coworkers. Instant messaging is the
multitasking tools of choice most people chatting over IM do other things at
the same time.The use of IM in workplace is less intrusive than the use of
phone, more immediate than email and has added advantage due to the ability to
detect presence.In order for institution to maximize increased business
productivity using instant messaging its imperative that organizations define
and publish ICT policies, guidelines and regulations.Overall IM boosts business
performance by making operations faster, more agile, and more efficient with
very little additional cost thus Organizations that deploy IM would reap
significant Return on Investment.Institutions should adopt IM meetings which
are be more efficient and less prone to straying off topic, because of the
relative effort of typing versus talking.Comment: 8 page
Podcasts as a conversational pedagogy
The use of technology such as podcasts, social networking sites, wikis, and Google docs for communicating information which supports teaching and learning in tertiary institutions is well documented (Bates, 2005). These tools have been shown to enhance traditional lectures and tutorials (Salmon, 2007). Little attention, however, has been given to the use of conversational approaches when using these tools and their potential in developing alternative pedagogical approaches to teaching. This article examines the use of a conversational style podcast in an online pre-service early childhood teacher education programme. The podcasts were initially used to disseminate information and respond to the students’ needs, however, their conversational use revealed a number of unexpected outcomes. Analysis of the podcast conversations that occurred between the two lecturers, and the student feedback to these, were used to identify unexpected outcomes for students enrolled in the programme. These included the ‘humanising’ of the e-learning environment and the sense of community that emerged. This paper argues that the affordance of conversational podcasts personalises the e-learning environment, enhances students’ and lecturers’ motivation, and engenders a greater connectedness with the university context
Energy Saving In Data Centers
Globally CO2 emissions attributable to Information Technology are on par with those resulting from aviation. Recent growth in cloud service demand has elevated energy efficiency of data centers to a critical area within green computing. Cloud computing represents a backbone of IT services and recently there has been an increase in high-definition multimedia delivery, which has placed new burdens on energy resources. Hardware innovations together with energy-efficient techniques and algorithms are key to controlling power usage in an ever-expanding IT landscape. This special issue contains a number of contributions that show that data center energy efficiency should be addressed from diverse vantage points. © 2017 by the authors.
