Infants who have started crawling wake up more often at night reveals a new study from the University of Haifa

Infants who have started crawling wake up more often at night compared to the period before the crawling, reveals a new study by Dr. Dina Cohen of the University of Haifa's Department of Counseling and Human Development.

The doctoral study, conducted under the supervision of Prof. Anat Scher, observed 28 healthy babies who were developing normally, examining them once every two to three weeks. Their motor development and sleeping habits were monitored from age 4-5 months and continued until age 11 months. Their sleep patterns were measured by a device called an ActiGraph that provides objective evaluations of sleep patterns, taken together with parental reports from diaries and questionnaires. The infants' crawling development and progress was observed and videoed by the researcher.

The study showed that the average age for the babies to begin crawling was 7 months, and that this was accompanied by an increase in the number of times they woke up at night, from an average of 1.55 times per night to 1.98 times (based on the ActiGraph measurements). The incidents of wakefulness also lasted longer, about 10 minutes on average, as per parental reports.

The study also found that the scope and complexity of the changes which included waking more frequently and moving around a lot during asleep were more pronounced among those who started crawling earlier. By contrast, those who started to crawl later demonstrated only one change: waking up more frequently.

The good news for parents: Within three months from the day crawling begins, the baby will generally return to the sleep patterns from before acquiring the new motor skill.

According to Dr. Cohen, there are a number of reasons why starting to crawl and wakefulness could be linked. "It is possible that crawling, which involves a vast range of changes and psychological reorganization in the babies' development, increases their level of arousal, influences their ability to regulate themselves and causes a period of temporary instability that expresses itself in waking up more frequently," she suggests.

Increased restlessness in babies who crawl early, she says, could be attributed to the baby's expressing fears of being physically distanced from the mother before fully developing the psychological mechanisms to cope with separation effectively. "This fear is likely to be expressed in sleep interruptions during the night," she explained.

"With ongoing monitoring of babies' development, we can demonstrate that the increased awakenings are a temporary short-term phenomenon, which occurs as part of a wider process of the baby's gradually improving ability to regulate states of sleep and wakefulness," adds Dr. Cohen.

Panasonic's Any Battery Light isn't picky about battery size, takes anything in your junk drawer

Battery nerds rejoice: Panasonic has cobbled together an electronic torch that will play nice with almost anything in your collection. The Any Battery Light can siphon power from AA, AAA, D and C-sized batteries, lighting the dark with just a single serving of any compatible size. Loading it up with all four provides up to 86 hours of continuous LED illumination. Not all batteries are equal, of course -- a single AAA isn't going to shine as brightly as its thicker cousins, and users will need to manually flip a switch to choose what size battery the torch draws its light from. Japanese consumers will be able to pick one up for about ¥2,000 ( $23) in red or white later this month.

New research helps explain why girls do better in school

Jan. 2, 2013 ? Why do girls get better grades in elementary school than boys-even when they perform worse on standardized tests?

New research from the University of Georgia and Columbia University published in the current issue of Journal of Human Resources suggests that it's because of their classroom behavior, which may lead teachers to assign girls higher grades than their male counterparts.

"The skill that matters the most in regards to how teachers graded their students is what we refer to as 'approaches toward learning,'" said Christopher Cornwell, head of economics in the UGA Terry College of Business and one of the study's authors. "You can think of 'approaches to learning' as a rough measure of what a child's attitude toward school is: It includes six items that rate the child's attentiveness, task persistence, eagerness to learn, learning independence, flexibility and organization. I think that anybody who's a parent of boys and girls can tell you that girls are more of all of that."

The study, co-authored by Cornwell and David Mustard at UGA and Jessica Van Parys at Columbia, analyzed data on more than 5,800 students from kindergarten through fifth grade. It examined students' performance on standardized tests in three categories??-reading, math and science-linking test scores to teachers' assessments of their students' progress, both academically and more broadly.

The data show, for the first time, that gender disparities in teacher grades start early and uniformly favor girls. In every subject area, boys are represented in grade distributions below where their test scores would predict.

The authors attribute this misalignment to what they called non-cognitive skills, or "how well each child was engaged in the classroom, how often the child externalized or internalized problems, how often the child lost control and how well the child developed interpersonal skills." They even report evidence of a grade bonus for boys with test scores and behavior like their girl counterparts.

This difference can have long-reaching effects, Cornwell said.

"The trajectory at which kids move through school is often influenced by a teacher's assessment of their performance, their grades. This affects their ability to enter into advanced classes and other kinds of academic opportunities, even post-secondary opportunities," he said. "It's also typically the grades you earn in school that are weighted the most heavily in college admissions. So if grade disparities emerge this early on, it's not surprising that by the time these children are ready to go to college, girls will be better positioned."

Research about gender differences in the classroom and beyond has grabbed headlines recently. Titles like Hannah Rosin's "The End of Men and the Rise of Women" and Kay Hymowitz's "Manning Up" have spent months on best-seller lists and inspired countless discussions in the media.

"We seem to have gotten to a point in the popular consciousness where people are recognizing the story in these data: Men are falling behind relative to women. Economists have looked at this from a number of different angles, but it's in educational assessments that you make your mark for the labor market," Cornwell said. "Men's rate of college going has slowed in recent years whereas women's has not, but if you roll the story back far enough, to the 60s and 70s, women were going to college in much fewer numbers. It's at a point now where you've got women earning upward of 60 percent of the bachelors' degrees awarded every year."

But despite changing college demographics, the new data may not be reflecting anything fundamentally new.

"My argument is that this has always been true about boys and girls. Girls didn't all of a sudden become more engaged and boys didn't suddenly become more rambunctious," Cornwell said. "Their attitudes toward learning were always this way. But it didn't show up in educational attainment like it does today because of all the factors that previously discouraged women's participation in the labor force, such as a lack of access to reliable birth control."

What remains unclear, however, is how to combat this discrepancy.

"The most common question we've gotten is whether or not the gender of the teacher matters in regards to grading students," Cornwell said. "But that's a question we can't answer because there's just not enough data available. As you can probably guess, the great majority of elementary school teachers are women."

Can diet beat depression?

Jan. 3, 2012 ? Research into diet and depression should follow the model of studies into diet and cardiovascular risk. So argue Almudena Sanchez-Villegas and Miguel A Mart?nez-Gonz?lez in an opinion piece, in BioMed Central?s open access journal BMC Medicine this week.

The authors, from the universities of Las Palmas and Navarra, assess the evidence into links between diet and depression and find it lacking. ?Depression is similar in many aspects to heart disease? they explained. ?Both are associated with low-grade inflammation, endothelial dysfunction and worse lipid profiles. This tends to suggest that the underlying causes, such as a diet high in trans fats, are also the same.?

Though there is plenty of evidence that there is an association, and that fast food increases risk of depression (while the Mediterranean diet decreases it), most of these studies do not show causality. Almudena Sanchez-Villegas continued, ?It is difficult to be sure that the diet is responsible for depression ? it could be that depressed people make bad food choices. Other study problems include ?confounders? which may influence dietary habits, such as marital status, exercise, alcohol (or smoking), medical conditions and social networks. Or simply genetics.?

Miguel A Mart?nez-Gonz?lez concluded, ?To address these issues we need long term, randomised clinical studies similar to ones successfully conducted for diet and cardiovascular disease risk. Only then will we really understand the impact of diet of depression.?

Pak assumes presidency of UN Security Council | Pakistan Today ...

  • PM will be in New York to chair January 21 open debate on peacekeeping

UNITED NATIONS?-?Pakistan on Tuesday assumed this month?s presidency of the UN Security Council and will hold special sessions on peacekeeping and counterterrorism.

?During its presidency, Pakistan will help Council members to forge consensus and bridge differences. Ours will be an effective presidency,? Pakistan?s Permanent Representative to the UN Masood Khan said.

Pakistan began its two-year term as non-permanent member of the 15-nation Security Council last year and will be the president of the UN body for January, the first time that Pakistan has assumed the rotational office of the UNSC during its present term.

Prime Minister Raja Pervez Ashraf would be in New York to chair the January 21 open debate on ?UN Peacekeeping: a Multidimensional Approach?, which would take a comprehensive view of UN peacekeeping.

Foreign Minister Hina Rabbani Khar would chair a ministerial level session on January 15 on counterterrorism.

Khan said the debate would provide an opportunity to the council members and the general UN membership to have a ?holistic view of the continuing threats and challenges posed by international terrorism and the best ways of formulating and implementing coherent and comprehensive responses to this menace?.

?We have put the difficult issue of counterterrorism on the agenda of the council for a special debate. Terrorism can only be rooted out through a comprehensive approach of deterrence, dialogue and development,? Pakistan?s UN envoy added.

Previously, Pakistan has been elected to the Security Council six times.

The UN Security Council has five veto-wielding permanent members ? the United States, Britain, France, Russia and China ? and 10 nations that are elected as non-permanent members without veto powers.

Apple airs new iPhone 5 commercial, Dream

Apple has aired a new ad for the iPhone 5, this time focused on the Do Not Disturb feature that lets you turn off Notification Center alerts for set periods of time.

Just turn on Do Not Disturb and your iPhone 5 knows not to ring, unless it's a call you really want.

Apple has aired many feature-specific ads the past. The best of which lately was the panorama photography ad, Cheese. This one, Dream, featuring the Williams sisters of tennis fame playing ping pong, doesn't seem as good as that. It's not terrible, mind you, just not particularly witty, engaging, or emotionally resonant.

And sadly, it airs on the same day Do Not Disturb has failed for many people, due to the year incrementing to 2013.
