By Belinda Goldsmith LONDON (Reuters) - Witnessing friends' vacations, love lives and work successes on Facebook can cause envy and trigger feelings of misery and loneliness, according to German researchers.
Researchers have been trying to figure out why social media is so popular. Some of their conclusions make us users seem a bit batty.
There appear to be physiological forces driving social media use. According toHarvard University research, self-disclosure spurs the release of dopamine, a neurotransmitter associated with rewarding feelings. The result: addiction.
Today there are over 5.9 billion mobile phone subscriptions worldwide, and for every one person who accesses the internet from a computer two do so from a mobile device. Given the ubiquity and rapidly expanding functionality of mobile technologies, UNESCO is enthusiastic about their potential to improve and facilitate learning, particularly in communities where educational opportunities are scarce. This Working Paper Series scans the globe to illuminate the ways in which mobile technologies can be used to support the United Nations Education for All Goals; respond to the challenges of particular educational contexts; supplement and enrich formal schooling; and make learning more accessible, equitable, personalized and flexible for students everywhere.
What happens to a community with no "digital shadow" on the web?
Every technological innovation today around a new smart-phone app or web platform improving quality of life in citiescomes with a caveat. What about the people who can’t access those tools? What about the people on the other side of the digital divide who lack access to home computers, Internet connections, unlimited data plans? These are the people who go "unmapped" in the geoweb.
Researchers like Graham struggle to measure this effect, in part because our concept of a static map is disappearing. Today, online maps are dynamic: They appear differently depending on when you view them, or where you view them from, or whether or not you’re logged into gmail while you do it. It’s increasingly hard, Graham says, “to get the sort of God’s eye view that you traditionally have when looking at a map of what’s out there and what’s being both produced and represented."
Digital technologies offer unprecedented access to data and information. Some governments are threatened by the free flow of information, but by attempting to control and censor the Internet, they jeopardize their society's development.
Las redes sociales en internet cuentan en total con más de mil millones de usuarios; en México, las principales plataformas son, en orden descendente: Facebook, Twitter, YouTube, Google Plus y (todavía) Hi5.
This post will review existing literature on Open Educational Resources, introducing five critiques: 1.) An under-theorisation of ‘openness’, in which the concepts of positive and negative liberty will be used to suggest a neglect of coherent theorisation concerning the practice of self-directed learning. 2.) The simultaneous privileging and rejection of institutional authority, where OER literature will be shown to endorse the reputations of established institutions while claiming liberation from them. 3.) The diminishing of the role of pedagogy, in which OER will be aligned with an untheorised learner-centred model of education. 4.) Humanistic assumptions of unproblematic self-direction and autonomy, and 5.) an alignment with the needs of capital, in which a Foucauldian interpretation of subjectivity will offer alternative perspectives on the notions of power and emancipation in OER discourse. It is suggested that these critiques may provide a framework for OER to develop a theoretically rigorous area of scholarship.
Can social media help to bring women out of the shadows of academia? Women shouldn’t be afraid of blogging or self-promotion, writes Athene Donald, who finds that the mentoring support offered in the academic blogosphere can help researchers at any level stamp out their fears.
