Wenger argues that there are three crucial characteristics of a community of practice: domain: a common interest that connects and holds together the community community: a community is bound by the shared activities they pursue (for example, meetings, discussions) around their common domain practice: members of a community of practice are practitioners; what they do informs their participation in the community; and what they learn from the community affects what they do.

The idea kids can access tools for learning 24 hours a day and can access learning not bound by the walls of the school is critical," Hobbs said. "It's indicative of what we mean by a 21st-century education."

Goerge Barkouris (62), who found himself homeless for the first time in his life during the massive wave of unemployment in 2010, lost his home last November. Barkuris had worked for over 25 years in music and radio production but lost a contract with the public sector due to cuts in 2001. He then worked as a freelancer until 2008, but "when the crisis hit it was impossible to make money to pay for my house," he said. He has now found shelter in Klimaka’s hostel for homeless people in exchange for contributing to its street work program, which consists of riding Klimaka’s van around the streets of Athens, handing out food and other assistance to people in need.

And if my stream is any indication, I’m not alone. For me, repression used to be a one man show. Now I am part of a broader movement — mass avoidance through social media.

Erikson’s Stages of Development  Erik Erikson, a German psychoanalyst heavily influenced by Sigmund Freud, explored three aspects of identity: the ego identity (self), personal identity (the personal idiosyncrasies that distinguish a person from another, social/cultural identity (the collection of social roles a person might play). Erikson’s psychosocial theory of development considers the impact of external factors, parents and society on personality development from childhood to adulthood. According to Erikson’s theory, every person must pass through a series of eight interrelated stages over the entire life cycle. Infant (Hope) – Basic Trust vs. Mistrust Toddler (Will) – Autonomy vs. Shame Preschooler (Purpose) – Initiative vs. Guilt School-Age Child (Competence) – Industry vs. Inferiority Adolescent (Fidelity) – Identity vs. Identity Diffusion Young Adult (Love) – Intimacy vs. Isolation Middle-aged Adult (Care) – Generativity vs. Self-absorption Older Adult (Wisdom) – Integrity vs. Despair
