If an anonymous or relatively new user changes a statistic or date by even a little bit, without justifying their edit, they are particularly likely to raise a red flag. If an individual continues to vandalize after being warned, then they may even be blocked from further editing.

keeps a full history of every change to every article

It is for this reason that readers must be particularly diligent in verifying Wikipedia against its external sources, as discussed above. It is also a good idea, if you feel uncomfortable about an article, to check its history for recent "bad-faith" edits. If you find a piece of uncorrected vandalism, you might even decide to help future users by correcting it yourself. That's a great feature of Wikipedia.

Wikipedia can be an excellent starting place for further research.

Students can compare information in Wikipedia with information in other encyclopedias or books in the library. As a general rule, contributors to Wikipedia are encouraged to cite their sources, but, of course, not all do. For the sake of verifiability, it is advisable to cite an article that has listed its sources. Most of our better articles have sections such as "References," "Sources," "Notes," "Further reading," or "External links," which generally contain such information.

The 2008/9 Wikipedia Selection for Schools is a selection of 5,500 articles deemed suitable for school children and has been checked and edited for this audience and protected against editing or vandalism. It contains about the equivalent content to a 20 volume encyclopaedia organized around school curriculum subjects, and is available online and as a free download for use by schools.

Educators can use Wikipedia as a way of teaching students to develop hierarchies of credibility that are essential for navigating and conducting research on the Internet.

75 per cent of them were for young males

“It certainly suggests the drugs are being abused,” says Gordon Floyd, president and CEO of Children's Mental Health Ontario. “There's a desire for the quick fix … the idea that – ‘oh, we'll fix this with a pill' – rather than spend a few months in counselling, is pretty appealing.”

ADHD is one of the most commonly diagnosed disorders of childhood, with core features that include an inability to focus, and hyper and impulsive behaviour. Increasingly, it's seen as a chronic condition that 60 per cent of kids never outgrow and one that experts estimate affects five per cent of children worldwide.

Boys are four times more likely to develop autism, three times more likely to suffer dyslexia, and two to three times more likely to be diagnosed with ADHD.

IMS figures show ADHD prescriptions for males have increased 50 per cent since 2005.

About 65 percent of the participants in the pilot said they would not buy another e-reader now if theirs was broken. Almost all the participants said they were interested in following the technology to its next stages, because they think a device that works well in academia would be worth having.

"I found the device difficult to use and not conducive to academic purposes," he said, and added, "But I can see how it can be used for pleasure reading."

What they liked best about the devices was: the battery life, the wireless connection and the portability of the e-reader; the fact that all the course reading was on one device; the ability to search for content; and the legibility of the screen, including the fact it could be read in full sunlight. The top five suggestions students had for improving e-readers were: improving the ability to highlight and annotate PDF files; improving the annotation tools; providing a folder structure to keep similar readings together; improving the highlighting function; and improving the navigation within and between documents on the reader (including having more than one document open at the same time for comparison).

"The Kindle would be better for an academic setting if the PDF format worked more effectively,"

"There would be a greater benefit realized if the devices could develop a better way to deliver the ubiquitous PDF document, which is used by many journals and libraries to deliver documents, and is the common format in which dissertations and theses are published and read by faculty," Temos said. "Some students said they spent a considerable amount of time printing PDF documents during the semester, and hardly ever referred back to them once the semester was over. I don't expect that is unusual."

In the past, we collected information not simply to know things. That was only the beginning. We also collected information to convert it into something larger than facts and ultimately more useful — into ideas that made sense of the information. We sought not just to apprehend the world but to truly comprehend it, which is the primary function of ideas. Great ideas explain the world and one another to us.

These ideas enabled us to get our minds around our existence and attempt to answer the big, daunting questions of our lives.

But if information was once grist for ideas, over the last decade it has become competition for them.

In effect, we are living within the nimbus of an informational Gresham’s law in which trivial information pushes out significant information, but it is also an ideational Gresham’s law in which information, trivial or not, pushes out ideas.

We prefer knowing to thinking because knowing has more immediate value. It keeps us in the loop

For one thing, social networking sites are the primary form of communication among young people, and they are supplanting print, which is where ideas have typically gestated. For another, social networking sites engender habits of mind that are inimical to the kind of deliberate discourse that gives rise to ideas.

Indeed, the gab of social networking tends to shrink one’s universe to oneself and one’s friends, while thoughts organized in words, whether online or on the page, enlarge one’s focus.

But because they are scientists and empiricists rather than generalists in the humanities, the place from which ideas were customarily popularized, they suffer a double whammy: not only the whammy against ideas generally but the whammy against science, which is typically regarded in the media as mystifying at best, incomprehensible at worst. A generation ago, these men would have made their way into popular magazines and onto television screens.

there is a vast difference between profit-making inventions and intellectually challenging thoughts.

There won’t be anything we won’t know. But there will be no one thinking about it.

Increasingly, undergraduates are not prepared adequately in any academic area but often arrive with strong convictions about their abilities.

It has become difficult to give students honest feedback.

As the college-age population declines, many tuition-driven institutions struggle to find enough paying customers to balance their budgets. That makes it necessary to recruit even more unprepared students, who then must be retained, shifting the burden for academic success away from the student and on to the teacher.

Although a lot of emphasis is placed on research on the tenure track, most faculty members are not on that track and are retained on the basis of what students think of them.

Students gravitate to lenient professors and to courses that are reputedly easy, particularly in general education.

It is impossible to maintain high expectations for long unless everyone holds the line in all comparable courses—and we face strong incentives not to do that.

Formerly, full-time, tenured faculty members with terminal degrees and long-term ties to the institution did most of the teaching. Such faculty members not only were free to grade honestly and teach with conviction but also had a deep understanding of the curriculum, their colleagues, and the institutional mission. Now undergraduate teaching relies primarily on graduate students and transient, part-time instructors on short-term contracts who teach at multiple institutions and whose performance is judged almost entirely by student-satisfaction surveys.

Contingent faculty members, who are paid so little, routinely teach course loads that are impossible to sustain without cutting a lot of corners.

Many colleges are now so packed with transient teachers, and multitasking faculty-administrators, that it is impossible to maintain some kind of logical development in the sequencing of courses.

Students may be enjoying high self-esteem, but college teachers seem to be suffering from a lack of self-confidence.

Or maybe the page has been moved and something else is where it used to be. This is known as “content drift,”

For the law and for the courts, link rot and content drift, which are collectively known as “reference rot,” have been disastrous.

According to a 2014 study conducted at Harvard Law School, “more than 70% of the URLs within the Harvard Law Review and other journals, and 50% of the URLs within United States Supreme Court opinions, do not link to the originally cited information.”

1961, in Cambridge, J. C. R. Licklider, a scientist at the technology firm Bolt, Beranek and Newman, began a two-year study on the future of the library, funded by the Ford Foundation and aided by a team of researchers that included Marvin Minsky, at M.I.T.

Licklider envisioned a library in which computers would replace books and form a “network in which every element of the fund of knowledge is connected to every other element.”

Licklider’s two-hundred-page Ford Foundation report, “Libraries of the Future,” was published in 1965.

Kahle enrolled at M.I.T. in 1978. He studied computer science and engineering with Minsky.

Vint Cerf, who worked on ARPAnet in the seventies, and now holds the title of Chief Internet Evangelist at Google, has started talking about what he sees as a need for “digital vellum”: long-term storage. “I worry that the twenty-first century will become an informational black hole,” Cerf e-mailed me. But Kahle has been worried about this problem all along.

The Internet Archive is also stocked with Web pages that are chosen by librarians, specialists like Anatol Shmelev, collecting in subject areas, through a service called Archive It, at archive-it.org, which also allows individuals and institutions to build their own archives.

Illien told me that, when faced with Kahle’s proposal, “national libraries decided they could not rely on a third party,” even a nonprofit, “for such a fundamental heritage and preservation mission.”

screenshots from Web archives have held up in court, repeatedly.

Perma.cc has already been adopted by law reviews and state courts; it’s only a matter of time before it’s universally adopted as the standard in legal, scientific, and scholarly citation.

It’s not possible to go back in time and rewrite the HTTP protocol, but Van de Sompel’s work involves adding to it. He and Michael Nelson are part of the team behind Memento, a protocol that you can use on Google Chrome as a Web extension, so that you can navigate from site to site, and from time to time. He told me, “Memento allows you to say, ‘I don’t want to see this link where it points me to today; I want to see it around the time that this page was written, for example.’ ”

and substantially determines if performers will suffer emotion-related detriments or profit from emotion-related benefits

Emotions that are too weak or intense and feel unpleasant lead to lower motivation, distracted attention, and reduced performance.

On the other hand, appropriately intense emotions which feel pleasant and are expected to help future performance are more likely to lead to increased effort, better decision making, and hence enhanced performance

Mann-Whitney U tests of mean ranks showed that compared to students who viewed performance as a threat (MThreat = 7.00, SDThreat = 0.99), students who viewed performance as a challenge (MChallenge = 5.02, SDChallenge = 1.91); reported significantly less cognitive anxiety at pre-recital (U = 21.00, z = -2.167, p = .028) and significantly higher self-confidence both at the start of semester, (MThreat = 4.79, SDThreat = 0.90; MChallenge = 6.42, SDChallenge = 1.08; U = 29.50, z = -3.555, p < .001) and pre-recital (MThreat = 4.45, SDThreat = 0.72; MChallenge = 6.55, SDChallenge = 0.98; U = 2.50, z = -3.104, p < .001, Figure 2).

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.
