during the week we had students reading my blog, seeing their snow hat from last winter being commented on by people all around the world and retweeted by Rihanna (a robot - I kept that quiet not to spoil the effect) on Twitter.

First day in class, we had students chatting with a friend of mine working on a Ski Resort in Australia,

I met with my friend Marcin Kleban. After a twenty minute discussion we started a project of 40 language teachers and learners, he trusted me.. I met with my friend Blaise Ngandeu, I was able to learn about Nexus Analysis from my friend Maritta Riekki.

I wrote about this experience here in Swings and Roundabouts.

So with social networking graphs, we will be able to get a better view on connections and their movement in the #rhizo14 constellation.

A network perspective not only lays bare the various stakeholders with a vested social, economic, and political interest in what happens within schools and colleges, but also the ways agency for what happens within classrooms at my institution extends beyond the students and educators charged with constructing learning.

When students see adults actually listening to them with respect, that is when they begin to realize they have a voice and can make a difference in their world.

If, at the dawn of the web, I was to take a list of things the web would bring about and show them to a researcher, they might disagree on the level of interest people would have in things (what’s with the cat pictures, spaceman?) but there’d be little there to surprise them except for one item: the most used reference work in the world will be collaboratively maintained by a group of anonymous and pseudonymous volunteers as part of a self-organizing network.

In this regard, it’s interesting to note that the viewing of TV programs at the time of their broadcast went up 20% with the advent of Twitter, indicating a desire to consume collaboratively. My ten year experience with social reading suggests that we might see a similar increase if long-form texts began appearing in platforms enabling people to gather in the margins with trusted friends and colleagues.

Meanwhile, in almost exactly the same decades that the Internet arose and eventually evolved social computing, literary scholarship followed similar principles of decentralization to evolve cultural criticism.7

Finally children do as we do, not as we say. That gives us incentive to bring play back into our adult lives. We can shut off the TVs and take our children with us on outdoor adventures. We should get less exercise in the gym and more on hiking trails and basketball courts. We can also make work more playful: Businesses that do this are among the most successful. Seattle’s Pike Fish Market is a case in point. Workers throw fish to one another, engage the customers in repartee, and appear to have a grand time. Some companies, such as Google, have made play an important part of their corporate culture. Study after study has shown that when workers enjoy what they do and are well-rewarded and recognized for their contributions, they like and respect their employers and produce higher quality work. For example, when the Rohm and Hass Chemical company in Kentucky reorganized its workplace into self- regulating and self-rewarding teams, one study found that worker grievances and turnover declined, while plant safety and productivity improved.

Emmons proposes a series of questions to help people recover from difficult experiences, which I’ve adapted for the workplace: What lessons did the experience teach us? Can we find ways to be thankful for what happened to us now, even though we were not at the time it happened? What ability did the experience draw out of us that surprised us? Are there ways we have become a better workplace because of it? Has the experience removed an obstacle that previously prevented us from feeling grateful?

Research points to the notion that gratitude might have positive effects on transforming conflicts, which can benefit the organization and working relationships. How do you do that? It starts with the one charged with mediating the conflict: For example, a supervisor with two bickering employees might open a meeting by expressing sincere appreciation of both parties. Throughout the process, that person should never miss an opportunity to say “thank you.” The research says this attitude of gratitude will have a positive feedback effect, even if results aren’t obvious right away.

Giving creates gratitude, but giving can also be a good way to express gratitude, especially if the person in question is shy. You can say “thanks” by taking on scut work, lending a parking space, or giving a day off. These kinds of non-monetary gifts can lead to more trust in working relationships, if it’s reciprocal, sincere, and altruistically motivated.

Employees need to hear “thank you” from the boss first. That’s because expressing gratitude can make some people feel unsafe, particularly in a workplace with a history of ingratitude.

The benefits of gratitude go beyond a sense of self-worth, self-efficacy, and trust between employees. When Greater Good Science Center Science Director Emiliana Simon-Thomas analyzed data from our interactive gratitude journal Thnx4.org, she found the greater the number of gratitude experiences people had on a given day, the better they felt. People who kept at it for at least two weeks showed significantly increased happiness, greater satisfaction with life, and higher resilience to stress; this group even reported fewer headaches and illnesses.

Gratitude is a non-monetary way to support those non-monetary motivations. “Thank you” doesn’t cost a dime, and it has measurably beneficial effects. In a series of four experiments, psychologists Adam Grant and Francesca Gino found that “thank you” from a supervisor gave people a strong sense of both self-worth and self-efficacy. The Grant and Gino study also reveals that the expression of gratitude has a spillover effect: Individuals become more trusting with each other, and more likely to help each other out.

when we set goals that are reallynon-zero that have to do with not only honoring our own interests, but also advancing thewelfare and interests of others, friends, family members, and social groups, that kindof a goal, that non-zero goal that really incorporates others interests with the greatergood is associated with greater success, career, and happiness.

So one of the principles of the talk, heroes are most effective not alone, not the, thesoldier in, in battle who takes a bullet for his buddy, but forming a network.

A study by James Fowler of the University of California, San Diego, and Nicholas Christakis of Harvard, published in the Proceedings of the National Academy of Science, shows that when one person behaves generously, it inspires observers to behave generously later, toward different people. In fact, the researchers found that altruism could spread by three degrees—from person to person to person to person. “As a result,” they write, “each person in a network can influence dozens or even hundreds of people, some of whom he or she does not know and has not met.”

Beyond education, the big challenge is figuring out how social networking technology can harness the power of empathy to create mass political action. Twitter may have gotten people onto the streets for Occupy Wall Street and the Arab Spring, but can it convince us to care deeply about the suffering of distant strangers, whether they are drought-stricken farmers in Africa or future generations who will bear the brunt of our carbon-junkie lifestyles? This will only happen if social networks learn to spread not just information, but empathic connection.

As important as close relationships are, weaker ties also have their place. Research suggests that people who have a broad range of different kinds of social roles tend to be healthier and more likely to attain professional success.

Since support can often become unequal, thus creating ingratitude and resentment, sometimes the most effective support is invisible—meaning that it is not experienced as support per se, but rather as a gesture of caring that is not costly or burdensome to the giver. For example, a person might choose to sacrifice work time to spend a romantic evening with their partner who has had a rough week, but this form of support will likely be better received if the person does not emphasize their sacrifice, but rather communicates a genuine desire to spend time with their partner. At the same time, however, Greater Good contributor Amie Gordon’s research shows that appreciation is a critical ingredient in healthy relationships, so it’s not always a bad thing to notice your partner’s sacrifices or to make sure that they know that you’re putting them first.

Stephanie Coontz, author of Marriage, a History has argued that the best way to maintain a strong, healthy marriage is to have a strong network of friends with whom we share common interests and can turn to when in need. While it might be tempting to be jealous of time your partner spends with friends, or possessive of his or her time, it’s healthier to see your partner’s friends as an asset to your relationship. They provide critical psychological support to your partner and an outlet for interests that you might not share. But your partner’s friendships are also a form of social capital for you—and it will pay to help your partner keep those networks going.

Significant others can deepen and broaden our social worlds, but they also carry the risk of creating a sense of insularity and disconnection from other parts of our social life. Staying in and watching a movie with our significant other can seem a lot more relaxing after a long week of work than attending a social event, but if we do this week after week, our other relationships may start to erode, decreasing our overall social capital. No matter how much we love our significant others, it’s unlikely that they alone can meet all of our social needs, and expecting them to do so can be damaging to the relationship over time.

Beyond the benefits we receive directly from our significant others in the form of support and comfort, our significant others also have the potential to introduce us to a whole new social network, the friendships and other connections that our partner has developed over the years. When we enter a partnership our networks double—our partner’s connections become ours as well, and vice versa.

Support in times of need is one of the major benefits of what researchers call bonding capital. Bonding capital may not give us the breadth and diversity of looser bridging-focused ties, but it gives us the closeness and intimacy that even 10,000 Twitter followers might not provide.

studies show that people with a large amount of bridging capital have a greater sense of connection to the broader community, a more open-minded attitude, and a greater ability to mobilize support for a cause.

Professional contacts can play an integral role in helping us launch or advance our careers. You might learn that your dream employer is hiring through a post from a seemingly random LinkedIn contact, or meet your future business partner through a colleague at a conference. Researchers have referred to these kinds of ties, as well as other types of looser connections such as neighborhood acquaintances, as bridging capital. Bridging capital may involve weaker ties, but the breadth and diversity of these ties can expose us to new ideas and opportunities beyond what is available in our narrower inner circles.

In short, it pays to be a giver on social media, not just a lurker or a taker.

What are their limitations? Facebook is no cure for loneliness, and the positive feelings gained may be short-lived. Though online contacts can be great when it comes to sharing everyday joys and challenges, there are times when no sympathetic emoticons can replace the comfort of a loved one’s physical presence. Using social media effectively requires knowing its limitations, and, as with a flaky friend, not expecting more from it than it can give.

 Studies suggest that online communication may especially benefit less extraverted individuals by giving them opportunities to provide support to others in a non-threatening environment, an experience that can in turn increase self-esteem and reduce depression. Contrary to popular opinion, research also shows that using Facebook can help satisfy our need for connection.

A lifelong friendship usually feels different than a casual acquaintance you make at a networking event or a friend you acquire on Facebook. Yet according to research, we need both weak ties and strong ties in order to build “social capital,” which researchers define as the web of relationships in our life and the tangible and intangible benefits we derive from them.

In our highly connected working world, we are hyper-exposed to other people. This means negative emotions and stress become even more contagious as we have high exposure to negative comments on news articles and social media; stressed body language of financial news shows; stressed out people on our subways and planes; and open office plans where you can see everyone’s nonverbals.
