Experimental psychology results may not be as strong as originally claimed

A project that reproduced 100 experimental psychology studies found the results of more than 60 were not as strong as researchers originally claimed.

A study, over a period of years from 2011, that attempted to conduct exactly the same experiments as 100 psychology studies published in psychology journals were often unable to replicate them (The Strait Times, August 29, 2015). The results of this study appear in the Science journal. The psychology studies replicated included tests of personality, relationships, learning, free will, and memory. More than 60 studies did not have the same results as the published results.

A psychologist from the University of Virginia conducted the Reproducibility Project. His team recruited more than 250 researchers, identified 100 studies published in 2008 in psychology journals, and rigorously reconstructed each of them in collaboration with the original researchers.

The Reproducibiltiy Project found no evidence of fraud or definitively false results. Instead, the Reproducibiltiy Project found that the published results were ‘not as strong’ as originally claimed.

Pir-E-Kamil - The Perfect Mentor by Umera Ahmed: book review

The Perfect Mentor pbuh (2011) is set in Lahore and Islamabad in Pakistan. The novel commences with Imama Mubeen in medical university. She wants to be an eye specialist.

Flaws in the Glass, a self-portrait by Patrick White: book review

The manuscript, Flaws in the Glass (1981), is Patrick Victor Martindale White’s autobiography. White, born in 1912 in England, migrated to Sydney, Australia, when he was six months old. For three years, at the age of 20, he studied French and German literature at King’s College at the University of Cambridge in England. Throughout his life, he published 12 novels. In 1957 he won the inaugural Miles Franklin Literary Award for Voss, published in 1956. In 1961, Riders in the Chariot became a best-seller, winning the Miles Franklin Literary Award. In 1973, he was the first Australian author to be awarded the Nobel Prize for Literature for The Eye of the Storm, despite many critics describing his works as ‘un-Australian’ and himself as ‘Australia’s most unreadable novelist.’ In 1979, The Twyborn Affair was short-listed for the Booker Prize, but he withdrew it from the competition to give younger writers the opportunity to win the award. His autobiography, Flaws in the Glass

Sister cities discussed: Canberra and Islamabad

Two months ago, in March 2015, Australia and Pakistan agreed to explore ways to deepen ties. The relationship between Australia and Pakistan has been strong for decades, and the two countries continue to keep dialogues open. The annual bilateral discussions were held in Australia in March to continue engagements on a wide range of matters of mutual interest. The Pakistan delegation discussed points of interest will include sports, agriculture, economic growth, trade, border protection, business, and education. The possible twinning of the cities of Canberra, the capital of Australia, and Islamabad, the capital of Pakistan, were also on the agenda (i.e. called twin towns or sister cities). Sister City relationships are twinning arrangements that build friendships as well as government, business, culture, and community linkages. Canberra currently has international Sister City relationships with Beijing in China and Nara in Japan. One example of existing
