ΟΟΣΑ: Εκπαιδευτική έρευνα PISA H Κύπρος θα συμμετάσχει στην έρευνα PISA 2012. Το συντονισμό και τη διεξαγωγή της έρευνας έχει αναλάβει το ΚΕΕΑ. Η PISA είναι μία διεθνής έρευνα που διεξάγεται από τον OECD (Organisation for Economic Cooperation and Development – Οργανισμός Οικονομικής Συνεργασίας και Ανάπτυξης) με σκοπό τη διεθνή αξιολόγηση των εκπαιδευτικών συστη­μάτων των χωρών που συμμετέχουν σε αυτόν. Συγκεκριμένα, η έρευνα στοχεύει στον καθορισμό αξιόπιστων δεικτών σε θέματα που σχετίζονται με τα μαθησιακά αποτελέσματα των εκπαιδευτικών συστημάτων (γνώσεις και δεξιότητες στους τομείς της Ανάγνωσης, των Μαθηματικών και των Φυσικών Επιστημών) κατά την περίοδο στην οποία η υποχρεωτική εκπαίδευση βαίνει ή βρίσκεται προς την ολοκλήρωσή της (στις περισσότερες χώρες). Η έρευνα διεξάγεται από το 2000 κάθε 3 χρόνια. Μετά από επίμονες προσπάθειες η Κύπρος θα μπορέσει να συμμετάσχει στην έρευνα PISA 2012. Η Πιλοτική Φάση (Field Trial) της έρευνας στην Κύπρο θα πραγματοποιηθεί το Μάρτιο και Απρίλιο του 2011. Κώστας Συμεωνίδης

The Meaning of Color Disciplines > Communication > The Meaning of Colors Meanings of color | Use in retail and business | Gender effects | Cultural effects | So what? Meanings of color Here is a table of colors and many of the meanings they tend to evoke, particularly in Western cultures. Notice how colors can mean very different things - it is not that the colors themselves have meaning, it is that we have culturally assigned meanings to them. For example, red means warmth because of the color of fire. Also: Temperature The more towards the red end of spectrum you go, the hotter it gets. Use in retail and business Here are some ways in which colors are used in retail and business: Color can even change what you taste. Gender effects Men and women see colors differently. Red has been associated with romance and an American experiment offering dates with identical pictures of the same woman in different colored dresses found that a red dress was most effective in stimulating male desire.

Nuclear reactor and power plant simulation Introduction This is not a lesson like the others in Radioactivity and Atomic Physics Explained but it fits in well with the lesson on nuclear power. It is a very sophisticated simulation of a pressurised water reactor (PWR), which is the most common type of nuclear power reactor in the US but not in Europe, though the principles are very similar. Using the tour There is a comprehensive tour which goes through the workings of the reactor, starting from a consumer of electrical energy and working backwards to the reactor core itself. You can restart the tour at any time using the button at the top left of the screen. Hint numbers Each part of the simulation has a hint number that you can click to see a description of its function. The skill test Once you're familiar with how to use the reactor you can see whether you can control the reactor so that the power output matches the demand from the city.

VAMNIES DIMITRIOS US and Israel were behind Stuxnet claims researcher 4 March 2011Last updated at 16:55 Iran's Bushehr reactor is believed to have been on of the intended targets for Stuxnet. Israel and the United States created the Stuxnet worm to sabotage Iran's nuclear programme, a leading security expert has claimed. Ralph Langner told a conference in California that the malicious software was designed to cripple systems that could help build an Iranian bomb. Mr Langner was one of the first researchers to show how Stuxnet could take control of industrial equipment. It is widely believed that its target was machinery used to enrich uranium. Speaking at the TED conference in Long Beach, California, Mr Langner said: "My opinion is that Mossad [Israel's intelligence agency] is involved." However he speculated that Israel was not the main driver behind the creation of Stuxnet. "There is only one leading source, and that is the United States," said Mr Langner. Stuxnet first came to light in July 2010. Damaging centrifuges
