90 Observing Emerging Student Networks on a Microblogging Service
MERLOT Journal of Online Learning and Teaching Vol. 7, No. 1, March 2011 Observing Emerging Student Networks on a Microblogging Service Joanne Badge Stuart Johnson School of Biological Sciences Student Development University of Leicester University of Leicester Leicester LE1 7RH, UK Leicester LE1 7RH, UK. [email protected] [email protected] Alex Moseley Alan Cann Course Design and Development Department of Biology Unit University of Leicester University of Leicester Leicester LE1 7RH, UK Leicester LE1 7RH, UK. [email protected] [email protected] Abstract The impact of social networks on lives of the majority of young adults has been enormous, although their impact on education is less well understood. Some consideration has been give to the role Facebook plays in higher education and in the transition from secondary to tertiary education, but little analysis has been conducted on the role of the microblogging social network Twitter. By examining the use made of this service by two cohorts of students, this study found that Twitter is easy for students to use and popular with the majority once they have experience with it. For this study different patterns of use between individuals in the study and between the two different student cohorts were observed, as was the emergence of informal online peer support networks. The results of this study suggest models for future use of microblogging services. Keywords: computer-mediated communication; cooperative/collaborative learning; Twitter, learning communities; learning spaces, microblogging Introduction For some time, students have used their mobile cell phones to maintain local and distant networks whilst studying at university or college. -
The Relationship Between Natural Environments and Subjective Well-Being As Measured by Sentiment Expressed on Twitter Yian Lin A
The Relationship Between Natural Environments and Subjective Well-being as Measured by Sentiment Expressed on Twitter Yian Lin A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science University of Washington 2021 Committee: Joshua J. Lawler Sunny L. Jardine Spencer A. Wood Program Authorized to Offer Degree: Quantitative Ecology and Resource Management © Copyright 2021 Yian Lin University of Washington Abstract The Relationship Between Natural Environments and Subjective Well-being as Measured by Sentiment Expressed on Twitter Yian Lin Chair of the Supervisory Committee: Joshua J. Lawler School of Environmental and Forest Sciences There is growing evidence that time spent in nature can affect well-being. Nonetheless, assessing this relationship can be difficult. We used social media data—1,971,045 geolocated tweets sent by 81,140 users from locations throughout Seattle, Washington, USA—to advance our understanding of the relationship between subjective well-being and natural environments. Specifically, we quantified the relationships between sentiment (negative/neutral/positive) expressed in individual geolocated tweets and their surrounding environments focusing on land- cover type, tree-canopy density, and urban parks. Controlling for multiple covariates such as location types and weather conditions, we estimated three random-intercept partial proportional odds models corresponding to the three environmental indicators. Our results suggest that for a given type of land-use, tweets sent from some -

The faster the better. A server side rendered web page can have a prominent initial load speed while a client side rendered web page will have a great interactive user experience. When combining the two, some users with a bad internet connection or a slow device could receive a poor user experience. -

Fawkes: Faster Mobile Page Loads Via App-Inspired Static Templating
Fawkes: Faster Mobile Page Loads via App-Inspired Static Templating Shaghayegh Mardani, UCLA; Mayank Singh, IIT Delhi; Ravi Netravali, UCLA https://www.usenix.org/conference/nsdi20/presentation/mardani This paper is included in the Proceedings of the 17th USENIX Symposium on Networked Systems Design and Implementation (NSDI ’20) February 25–27, 2020 • Santa Clara, CA, USA 978-1-939133-13-7 Open access to the Proceedings of the 17th USENIX Symposium on Networked Systems Design and Implementation (NSDI ’20) is sponsored by Fawkes: Faster Mobile Page Loads via App-Inspired Static Templating Shaghayegh Mardani*, Mayank Singh†, Ravi Netravali* *UCLA, †IIT Delhi Abstract Despite the rapid increase in mobile web traffic, page loads still fall short of user performance expectations. State-of- Mobile the-art web accelerators optimize computation or network App fetches that occur after a page’s HTML has been fetched. However, clients still suffer multiple round trips and server processing delays to fetch that HTML; during that time, a browser cannot display any visual content, frustrating users. This problem persists in warm cache settings since HTML is most often marked as uncacheable because it usually embeds Web a mixture of static and dynamic content. Page Inspired by mobile apps, where static content (e.g., lay- out templates) is cached and immediately rendered while dynamic content (e.g., news headlines) is fetched, we built 300 ms 1100 ms 2900 ms Fawkes. Fawkes leverages our measurement study finding Figure 1: Comparing the mobile app and mobile web browser that 75% of HTML content remains unchanged across page loading processes for BBC News over an LTE cellular network. -
Performance Enhancement of Webpage Using Progressive Web App Features

Karpagam, Padmavathe. R, Professor/IT Department IV Information Technology Sri Ramakrishna Engineering College Sri Ramakrishna Engineering College Coimbatore, India Coimbatore, India Lakshana. R, Priyadharshini.S IV Information Technology IV Information Technology Sri Ramakrishna Engineering College Sri Ramakrishna Engineering College Coimbatore, India Coimbatore, India Manuscript History Number: IJIRAE/RS/Vol.04/Issue03/MRAE10102 Received: 07, March 2017 Final Correction: 20, March 2017 Final Accepted: 28, March 2017 Published: March 2017 Abstract— The progressive web application combines the best of web and mobile apps. It is a website built using web technologies that acts like an app. Recent advancements in the browser, availability of service workers, Cache and Push APIs have enabled web developers to allow users to install web apps to their home screen, receive push notifications and even work offline. To use a traditional app, the user must install it beforehand which includes multiple clicks making the app unappealing to the user. This problem is solved by using PWA enabled webpage. The user is given the advantage of accessing the webpage app-like by creating a desktop icon which eliminates the need for multiple clicks. The primary characteristic of this progressive web app is that it must work on all devices and must enhance on devices and browsers that allow it. They take advantage of the much larger web ecosystem, plugins and community and the relative ease of deploying and maintaining a website when compared to a native application in the respective app stores. -
