Särskilt begåvade elever behöver anpassad undervisning
I varje grundskoleklass finns statistiskt sett 1-2 elever som har en särskild begåvning. Det innebär att eleverna ofta har lättare att ta till sig ny information, komma ihåg den och att de kan bearbeta den snabbare än jämnåriga. Svensk skola strävar efter att vara inkluderande, trots detta är det vanligt att den här gruppen elever ofta ”sitter av” sin skoldag. Antingen för att de redan kan det so

UTSA researcher studies bias in prosecutor filing trends
UTSA Criminal Justice professors Richard Hartley and Rob Tillyer have studied the factors affecting whether prosecutors decline to charge someone arrested for a federal crime. Their research is aimed at understanding prosecutorial discretion and its influence as gate keeper of the federal criminal justice system. The research revealed disparities related to charging decisions, charge reductions, g

Trump Laid a Trap on Immigration—And Only Beto Sees It
Beto O’Rourke isn’t known for his wonkish heft. But in his formal announcement for president on Sunday, the former Texas congressman offered one of the most important policy proposals of the nascent presidential campaign: He argued that to solve America’s problems at the border, America’s leaders must “help people in Central America where they are.” In so doing, he began laying a foundation to ef

How to Save the News Media
A nightmare. A wasteland. A place of confusion and half-truth. Ask Americans these days for their impressions of the news media and they are likely to produce such grim descriptions.

Eight Steps to Shrink the Israeli-Palestinian Conflict
One evening, about five years ago, I approached a small group of students. They were at Ein Prat, an institution that I head in Israel, where some 3,000 young Israelis have studied in recent years. Some are very religious, others deeply secular, but they share a deep connection. I asked the students what binds them together. One got up and said something that caused the group to burst into laught

Tilbage i 2009 besluttede Folketinget at sikre alle overkørsler på statsbanerne, men i dag er 51 overkørsler på statsbanerne og mere end 100 på lokalbanerne stadig ikke sikret.

New evidence on the association of shortened sleep time and obstructive sleep apnea with sleepiness and cardiometabolic risk factors
A new study in the journal CHEST® may change the way we think about sleep disorders. Obstructive sleep apnea (OSA) and short sleep duration (SSD) were compared with excessive daytime sleepiness; anxiety/depressive symptoms; and several cardiometabolic risk factors including obesity, hypertension, diabetes and dyslipidemia. Using a large sample of adults, investigators found that SSD, but not OSA,
