Facebook concept used by 16th century scholars

Jan. 15, 2013 ? Our obsession with social networking is not exclusive to the 21st century, according to researchers from Royal Holloway university.

The idea of creating networks of members and sharing information dates back to the 16th century Italian Academies, which saw young scholars create nicknames for themselves and develop emblems and mottoes to form groups with which they exchanged information.

The discovery was made during a ?1,130,000 collaborative research project between Royal Holloway, the British Library and Reading University, in which a team of academics are cataloguing and investigating the works of the Italian Academies, dating from 1525 to 1700. The project provides information about the academies, their members, publications, activities and emblems.

Researchers were surprised to realise just how similar the activities of these 16th and 17th century scholars were with society today.

Professor Jane Everson, Principal-investigator, said: "Just as we create user names for our profiles on Facebook and Twitter and create circles of friends on Google plus, these scholars created nicknames, shared -- and commented on -- topical ideas, the news of the day, and exchanged poems, plays and music.

"It may have taken a little longer for this to be shared without the internet, but through the creation of yearbooks and volumes of letters and speeches, they shared the information of the day."

The scholars created satirical names for their academies such as Gelati and Intronati. Professor Everson explains: "They are jokey names, which really mean the opposite of what they say. Intronati has nothing to do with thrones; it means dazed, stunned, knocked out and so not able to think straight -- but really the Intronati were engaged in serious study, debates, dramatic performances and the like from the moment they were founded in the 1520s -- and they are still as active as ever in their home city of Siena. The Gelati were not going around singing 'just one cornetto'. Gelati means the frozen ones -- so a pun on the fact that these academicians far from being totally inactive through being frozen cold, were busy debating, exploring ideas, challenging received opinions and changing the cultural world of their home city of Bologna, and indeed of Italy and far beyond."

Just as the names of the academies and the nicknames of the individual members were fun, so are the emblems and mottos which illustrate the name of the academy. The scholars took great delight in creating puzzling emblems with hidden meanings.

Professor Everson adds: "They do sometimes take some working out, but it is great fun when you can see the hidden meanings in the images."

Yemen raid nets two al Qaeda militants: security sources

SANAA (Reuters) - Yemeni security forces arrested two al Qaeda militants near the capital Sanaa on Monday, seizing explosives, suicide bomb vests, assassination manuals and lists of targets for attack, security sources said.

Although a third man escaped the raid on a hideout at Jader village, 14 km (9 miles) north of Sanaa, the arrests are likely to be seen as progress in government attempts to stem a spate of killings of security officials by suspected militants.

Al Qaeda in the Arabian Peninsula (AQAP), which is based in Yemen, is seen by U.S. officials as the most dangerous offshoot of the transnational militant network. Yemen's location next to top oil producer Saudi Arabia and major shipping lanes has made restoring its stability an international priority.

There have been dozens of kidnappings and assassinations of security and military officials by suspected al Qaeda gunmen in the past year, suggesting AQAP remains resilient despite increased U.S. drone strikes and a government military onslaught.

"The cell was planning operations that target national interests ... authorities are seeking to capture the remaining members of the cell that managed to escape and put them on trial," the security source said.

The hideout contained assassination instruction manuals, lists of targets and clippings of newspaper articles tracking a recent series of assassinations of Yemeni security officers, said a statement from the Yemeni embassy in Washington.

"One of the cell members impersonated a police officer to rent the house four months ago. The cell also used motorbikes for transportation. It is worth noting that assassins riding motorbikes have killed 40 officers and injured dozens in Yemen during 2012," the embassy statement added.

Most such arrests in recent months have been in the south, where Islamist fighters, emboldened by political instability, gained ground in late 2011 and early 2012 before being driven out in a U.S.-backed military campaign.

Formed in 2009, AQAP has carried suicide attacks on tourists and diplomats together with operations against neighboring Saudi Arabia and U.S. targets abroad.

Am I Really Bad at Public Speaking? The Problem of Self Perception ...

We often think we're worse public speakers than we are.

Steven?s Mum thinks he?s a great speaker.? For all his experience, the truth is, she?s probably a better judge than he is.

On Thursday night, my mum who is visiting from Australia came to her first Toastmasters Meeting. ?She was extremely impressed with the calibre of each and every speaker, who spoke during the evening, including myself (she is just being a proud mum!).

Speaking to her on our journey home, made me realise that our own perceptions of how we perform, can sometimes be completely different to how audience may view our performance. ? ?A poor speaking performance may not be as bad as you think. ?It is important to receive feedback from both experienced toastmasters and the average person on the street. ?But more importantly you need absorbe the feedback and determine how can it help in your development.

Each time you stand up in front of the audience is another small step in your development. ? Using each speech wisely to focus on an area of feedback, will result in quicker progress, instead of viewing each speech as simply an ?opportunity? to speak.

Steven

Eastern Europe: Tree rings reveal climate variability and human history

Jan. 14, 2013 ? A total of 545 precisely dated tree-ring width samples, both from living trees and from larch wood (Larix decidua Mill.) taken from historical buildings in the northern Carpathian arc of Slovakia, were used to reconstruct May-June temperatures yearly back to 1040 AD. The tree-ring data from the Tatra Mountains best reflects the climate history of Eastern Europe, with a geographical focus on the Baltic. The tree-ring record reveals several cold phases around ~1150, 1400, and in the 19th century. Mild springtime conditions occurred in the first half of the 12th century, as well as from ~1400-1780. The amount of climate warming since the mid-20th century appears unprecedented in the millennium-long context.

In addition to the development of the tree ring-based temperature history, the interdisciplinary research team* compared past climate variability with human history. Plague outbreaks, political conflicts and migration movements often matched periods of cooler temperatures. Moreover, fluctuations in settlement activity appear to be linked to climate variability. The Black Death in the mid-14th century, the Thirty Years War between ~1618-1648 and the Russian crusade of Napoleon in 1812 are three most prominent examples of climate-culture interactions.

The new evidence from Eastern Europe partially confirms similar observations from previous dendroclimatological investigations in Central Europe. However, the lead author of both studies, Ulf B?ntgen, is cautious about making simplified conclusions: ?the relationship between climate and culture is extremely complex and certainly not yet well enough understood. Nevertheless, we now better recognize that well documented and carefully analyzed tree-ring chronologies can contain much more information than supposed so far?. Thus, more data, independent studies and interdisciplinary approaches are of great interest for the enhancement of future knowledge.
