    important for all us educators to remember: knowledge and extractive industries do not mix. "Across all U.S. metros, the share of workers in resource and extractive industries had no correlation whatsoever to four key measures of regional development: economic output per capita, average wages per capita, income, or median household income (the correlations range from -.08 to .09, none being statistically significant). Conversely, the share of workers employed in idea-based knowledge and creative industries was strongly associated with all four regional development measures (with correlations ranging from .53 to .74). In line with the resource curse hypothesis, the share of employment in resource and extractive industries was negatively associated with share of employment in knowledge industries and also with the share of adults with college degrees, a key measure of skill and human capital which economists uniformly find to be a key driver of short and long-run economic prosperity."

    This research explores how strength of network ties, as fostered by the use of a social network site, Facebook, (a) influences alumni attitudes toward volunteering for and making charitable gifts to their alma mater, and (b) fortifies consistency between attitude and behavior. After exploratory interviews and participant observation, a survey of 3,085 alumni was conducted for hypothesis testing. Structural equation modeling analysis revealed: First, active participation in Facebook groups positively predicted strength of network ties along 2 dimensions: frequency of communication and emotional closeness. Second, both dimensions of tie strength influenced actual behavior, albeit via different routes. The paper also contributes to attitude change research in showing that strength of network ties can help ensure consistencies between attitude and behavior.

    "It is often claimed that people who are bilingual are better than monolinguals at learning languages. Now, the first study to examine bilingual and monolingual brains as they learn an additional language offers new evidence that supports this hypothesis, researchers say. The study, conducted at Georgetown University Medical Center and published in the journal Bilingualism: Language and Cognition, suggests that early bilingualism helps with learning languages later in life."

  • music performance anxiety (MPA)
  • The concept of “flow”, describing the subjective psychological state in which a person is completely immersed and fully concentrated in an activity which is enjoyable and rewarding, is often associated with optimal functioning
  • Anxiety is generally regarded as having an antithetical relationship with flow
  • ...19 more annotations...
  • The clinical implications of this negative association between MPA and flow suggest that a two-pronged approach focusing on facilitating flow and positive functioning as well as reducing pathological MPA may bring about improvements in the performer’s subjective performing experienc
  • Seligman’s (2011) most recent model of well-being, from the field of positive psychology, understands well-being as comprising five elements: Positive emotion, Engagement, Relationships, Meaning and Achievemen
  • There is a substantial body of Music Performance Anxiety (MPA) research providing evidence that MPA is a debilitating phenomenon (Kenny, 2011) which can affect musicians at any stage of their careers, from highly experienced professional performers (Fishbein, Middlestadt, Ottati, Straus, & Ellis, 1988; Kenny, Driscoll, & Ackerman, 2014) through to child beginners
  • Anxiety is often described as having an antithetical relationship to the experience of flow (Csikszentmihalyi, 1975), and it has been suggested that fostering techniques for facilitating flow may provide a powerful tool for reducing MPA and encouraging optimal performance
  • “when performance anxiety was highest, flow was lowest and vice versa … the presence of one minimises the magnitude of the other” (Fullager et al., 2013, p. 251), and a recent study found evidence of a strong, significant negative association between flow and MPA amongst 200 professional orchestral musicians (Cohen & Bodner, 2018), supporting Kirchner et al.’s (2008) earlier findings with music students
  • Investigations of the efficacy of existing methods for treating MPA indicate that Cognitive Behavioural Therapy based interventions are most effective (for an overview, see Burin & Osorio, 2016).
  • However, evidence suggests that pharmacological methods, particularly beta-blockers, are most commonly used, often in the absence of medical supervision (Cohen & Bodner, 2018; Kenny et al., 2014) and that the subject of MPA is still stigmatised, with many musicians and teachers unwilling to talk openly about it
  • Csikszentmihalyi’s nine dimensions of flow as follows
  • Although there was an increase in flow over time, this was not significant, F(1, 20) = 4.27, p > .05, η2 =.18, and there was no evidence of a significant interaction between group and time, F(1, 20) = 0.56, p > .05, η2 = .03, indicating that the hypothesis that there would be an increase in self-reported levels of flow in the intervention group, was not supported.
  • Figure 4. Judge-rated musical performance quality and signs of performance anxiety in the intervention group.
  • These results support the fourth hypothesis that there would be an increase in judge-rated PQ and a decrease in judge-rated SPA.
  • Results showed evidence of a significant negative association between MPA and flow, and three out of the four study hypotheses were supported: the music performance skills intervention was found to be effective in reducing pre-/post-test MPA in the intervention group compared to the wait-list control group; there were significant improvements in positive and negative affect and state anxiety associated with the performance situation in the intervention group; and there were significant improvements in judge-rated PQ and behavioural signs of performance anxiety. However, there was no significant change in pre-/post-test measures of flow. These findings will now be discussed in more detail.
  • This supports the understanding of MPA as a specific type of anxiety, where the performer suffers from MPA without necessarily being generally anxious or impaired in any other areas of his/her life (Clark & Williamon, 2011; Hoffman & Hanrahan, 2011) and corresponds to Kenny’s (2011) description of the first and most mild of three types of MPA (for full coverage of this issue, see Kenny, 2011).
  • Thus, the absence in improvement in levels of flow in the current study could also be due to the low average hours of daily practice reported
  • The increases in participants’ positive affect and decreases in negative affect after the second simulated performance compared to the first indicate that the intervention was effective in facilitating positive emotion, the first component of Seligman’s (2011) PERMA model of well-being
  • Evidence of improvements in judge-rated performance quality indicate that the intervention was also effective in facilitating the fifth (Achievement) component of the PERMA model.
  • “Ironically, it may be that the last people to receive some benefit from the therapeutic value of music may be the musicians themselves” (Brodsky, 1996, p. 95).
  • Hopefully, such an approach will enable developing musicians to acquire the skills necessary to enjoy satisfying, successful and healthy lives as performing musicians, in which the threat of debilitating MPA and the need to recourse to beta-blockers are a thing of the past.

    From site: Although YouTube has something of a reputation as a repository for the inane mental diarrhea of stunted man-children injuring each other for cheap laughs or shrill teenage drama queens shrieking like harpies over the latest bland, interchangeable lump passing as the epitome of masculine beauty, many others thankfully take advantage of its services as a portal to share their knowledge and educate viewers. While few of the scientific offerings formally follow the scientific method or test an explicitly stated hypothesis, even those videos veering more towards demonstrating various principles, theories, and laws still offer visitors a chance to learn something about how the world around them operates.

  • Web annotations are another form of online commentary. But unlike comments at the bottom of a blog, annotation tools such as Hypothes.is take the form of digital sticky notes. Readers can share their thoughts right next to text they highlight on a web page. The difference is that anyone we share our annotations with (colleagues, friends, students, for instance) can gain insight into our thinking and join a conversation about that digital text.

  • It would be more plausible and empirically rigorous, then, to consider how specific forms of Internet activity impact civic and social engagement as a result of their particular underlying social architectures
  • combining conclusions from two different lines of MMO research conducted from two different perspectives—one from a media effects approach, the other from a sociocultural perspective on cognition and learning.
  • By providing spaces for social interaction and relationships beyond the workplace and home, MMOs have the capacity to function as one form of a new "third place" for informal sociability much like the pubs, coffee shops, and other hangouts of old.

  • in this section we analyze the structural form of MMOs that warrants this "third place" assertion.
  • eight defining characteristics of third places
  • there is no default obligation
  • To oblige any one person to play requires that explicit agreements be entered into by parties
  • the default assumption is that no one person is compelled to participate legally, financially, or otherwise.
  • Unless one transforms the virtual world of the game into a workplace (e.g., by taking on gainful employment as a virtual currency "farmer" for example, Dibbell, 2006; Steinkuehler, 2006a) or enters into such agreement, no one person is obligated to log in

      and this is why, in my opinion, you will never see games in school. The game cannot be the Third Place because school is a Second Place.
  • Yee's (2006) interviews also reveal that individuals who game with romantic partners or family find that such joint engagement in the "other world" of MMOs allows them to redefine the nature and boundaries of their offline relationships, often in more equitable terms than what may be possible in day-to-day offline life
  • the relationships that play-partners have with one another offline are often "leveled" within the online world
  • an individual's rank and status in the home, workplace, or society are of no importance
  • appeal to people in part because they represent meritocracies otherwise unavailable in a world often filled with unfairness
  • conversation plays an analogous role
  • "In all such systems, linguistic interactions have been primary: users exchange messages that cement the social bonds between them, messages that reflect shared history and understandings (or misunderstandings) about the always evolving local norms for these interactions" (p. 22).
  • third places must also be easy to access
  • such that "one may go alone at almost any time of the day or evening with assurance that acquaintances will be there"
  • accessible directly from one's home, making them even more accommodating to individual schedules and preferences
  • barriers to initial access.
  • "What attracts a regular visitor to a third place is supplied not by management but by the fellow customer,"
  • "It is the regulars who give the place its character and who assure that on any given visit some of the gang will be there"
  • affective sense
  • As one informant satirically commented in an interview, "You go for the experience [points], you stay for the enlightening conversation.
  • engendering a sense of reliable mentorship and community stability.
  • Oldenburg argues that third places are characteristically homely, their d�cor defying tidiness and pretension whenever possible. MMOs do not fit this criterion in any literal sense
  • In neither of our investigations did the degree of formality exhibited by players within the game bear any relation to the degree of visual ornamentation of the players' immediate vicinity.
  • Thus, while the visual form of MMO environments does not fit Oldenburg's (1999) criterion of "low profile," the social function of those environments does.
  • Oldenburg (1999) argues that seriousness is anathema to a vibrant third place; instead, frivolity, verbal word play, and wit are essential.
  • The playful nature of MMOs is perhaps most apparent in what happens when individuals do bring gravity to the game.

  • Are virtual communities really communities, or is physical proximity necessary?
  • Anderson (1991), who suggests that geographic proximity itself is neither a necessary nor sufficient condition for the emergence and preservation of "community."
  • Social capital (Coleman, 1988) works analogously to financial capital; it can be acquired and spent, but for social and personal gains rather than financial
  • operates cyclically within social networks because of their associated norms of reciprocity
  • bridging social capital is inclusive.
  • This form of social capital is marked by tentative relationships, yet what they lack in depth, they make up for in breadth.
  • On the one hand, bridging social capital provides little in the way of emotional support; on the other hand, such relationships can broaden social horizons or worldviews, providing access to information and new resources.
  • bonding social capital is exclusive.
  • social superglue.
  • it can also result in insularity.
  • shows that bridging and bonding social capital are tied to different social contexts, given the network of relationships they enable.
  • Virtual worlds appear to function best as bridging mechanisms rather than as bonding ones, although they do not entirely preclude social ties of the latter type.
  • One could argue that, if the benchmark for bonding social capital is the ability to acquire emotional, practical, or substantive support, then MMOs are not well set up for the task:
  • While deep affective relationships among players are possible, they are less likely to generate the same range of bonding benefits as real-world relationships because of players' geographic dispersion and the nature of third places themselves.
  • Despite differences in theoretical grounding and methodologies, our conclusions were remarkably similar across complementary macro- and micro-levels.
  • It is worth noting, however, that as gamers become more involved in long-term social networks such as guilds and their activities become more "hardcore" (e.g., marked by participation in large-scale collaborative problem-solving endeavors such as "raids" into difficult territories or castle sieges), the function of MMOs as "third places" begins to wane.
  • It may be, then, that the structure and function of MMOs as third places is one part of the "life cycle" for some gamers in a given title.
  • In such cases, MMOs appear to enable a different kind of sociability, one ostensibly recognizable as a "community" nonetheless.
  • However, our research findings indicate that this conclusion is uninformed. To argue that MMO game play is isolated and passive media consumption in place of informal social engagement is to ignore the nature of what participants actually do behind the computer screen
  • Perhaps it is not that contemporary media use has led to a decline in civic and social engagement, but rather that a decline in civic and social engagement has led to retribalization through contemporary media (McLuhan, 1964).
  • Such a view, however, ignores important nuances of what "community" means by pronouncing a given social group/place as either wholly "good" or "bad" without first specifying which functions the online community ought to fulfill.
  • Moreover, despite the semantics of the term, "weak" ties have been shown to be vital in communities, relationships, and opportunities.
  • is to what extent such environments shift the existing balance between bridging and bonding
  • In light of Putnam's evidence of the decline of crucial civic and social institutions, it may well be that the classification "lacking bridging social capital" best characterizes the everyday American citizen. T
  • Without bridging relationships, individuals remain sheltered from alternative viewpoints and cultures and largely ignorant of opportunities and information beyond their own closely bound social network.
  • it seems ironic that, now of all times, we would ignore one possible solution to our increasingly vexed relationship with diversity.
