Emotional Contagions in Social Networks

These results highlight several features of emotional contagion. First, because News Feed content is not “directed” toward anyone, contagion could not be just the result of some specific interaction with a happy or sad partner. Although prior research examined whether an emotion can be contracted via a direct interaction (1, 7), we show that simply failing to “overhear” a friend’s emotional expression via Facebook is enough to buffer one from its effects. Second, although nonverbal ...

 Lower Mortality in Moderate Drinkers VS Abstainers Result...

RESULTS: Without adjustment, meta-analysis of all 87 included studies replicated the classic J-shaped curve, with low-volume drinkers (1.3-24.9 g ethanol per day) having reduced mortality risk (RR = 0.86, 95% CI [0.83, 0.90]). Occasional drinkers (<1.3 g per day) had similar mortality risk (RR = 0.84, 95% CI [0.79, 0.89]), and former drinkers had elevated risk (RR = 1.22, 95% CI [1.14, 1.31]). After adjustment for abstainer biases and quality-related study characteristics, no significant r...

The secret to succeeding with computers is to lutz with them. BART EISENBERG: Push buttons, move text, insert lines, hit control characters, add dot commands, bring up menus, invoke commands and invoke more of them. Try it backwards, try it sideways, try it upside down. The method, lf you can call it that, is vaguely scientific-in that you perform some action and observe the results. A playful attitude will get you further with these machines than weeks of serious endeavor.

 Theoretical Uncertainty has No Meaning

If one looks at the history of knowledge, it is plain that at the beginning men tried to know because they had to do so in order to live. In the absence of that organic guidance given by their structure to other animals, man had to find out what he was about, and he could find out only by studying the environment which constituted the means, obstacles and results of his behavior. The desire for intellectual or cognitive understanding had no meaning except as a means of obtaining greater secur...

 Busyness Correlated with Improved Cognitive Performance

Sustained engagement in mentally challenging activities has been shown to improve memory in older adults. We hypothesized that a busy schedule would be a proxy for an engaged lifestyle and would facilitate cognition. Here, we examined the relationship between busyness and cognition in adults aged 50–89. Participants (N = 330) from the Dallas Lifespan Brain Study (DLBS) completed a cognitive battery and the Martin and Park Environmental Demands Questionnaire (MPED), an assessment of busyness...

 1.9 Cases of Leukemia per 10,000 CT Scans in Children

In the breakdown of results, the study authors from Group Health Research Institute and University of California, Davis note that the risk of developing leukemia was highest from head scans for kids under age 5 with a rate of 1.9 cases per 10,000 CT scans. Younger children and girls seemed more susceptible to solid cancers than older kids and boys. Every 300 to 390 scans of a girl’s abdomen or pelvis was associated with the development of one solid cancer. The study estimates that 4,870 fut...

 Understanding Creativity Enabled Through Information Tech...

Here’s the question I’ve been asking myself: When technology enables a person to make something that looks professional without having to master any degree of craft, does that increase or decrease the likelihood of creativity? And can educators be lulled into a false impression that they have been developing creativity in students when using technologies that produce brilliantlooking results? Does my Wordle cloud give only the illusion of creativity? A number of software applications are...

 Jay Rosen: Information Overload

Filters in a digital world work not by removing what is filtered out; they simply don't select for it. The unselected material is still there, ready to be let through by someone else's filter. Intelligent filters, which is what we need, come in three kinds: A smart person who takes in a lot and tells you what you need to know. The ancient term for this is "editor." The front page of the New York Times still works this way. An algorithm that sifts through the choices other smart people have...

 Standing Desks Improve Student Engagement

The research looked at the results of an experiment in which 282 participants in grades 2-4 were observed in the fall and spring during one school year. Student engagement was monitored by actions such as answering a question, raising a hand, or participating in discussion, while off-task behaviors included talking out of turn. Engagement of the "treatment" classrooms was compared with the engagement of "control" classrooms. The researchers noted that both groups showed "general increases in...

 Quantity of Time Spent with Children has No Impact on Out...

Does the amount of time children spend with their mothers matter for children’s behavioral, emotional, and academic outcomes? The results from ordinary least squares regression models for the child sample are shown in Table 2. There were no statistically significant associations between maternal time of either type and any child outcome. In contrast, social status resources, as measured by mother’s education, family income, and family structure, was related to some outcomes. Mother’s ed...
