Aemilianus
Aemilianus or Aemilian (–253) was Roman emperor for eighty-eight days in 253 AD.
Aemilianus was born around 207 or around 214. The "Epitome de Caesaribus" (a Latin history) and Zonaras (a Greek historian) say that Aemilianus was born at this time and at Djerba, an island in the Mediterranean Sea near Africa, part of the Roman Empire.
Aemilianus was not from the nobility, and may have been from among the Moorish people.
Aemilianus was a senator and was a Roman consul, either in 252 or 253. He was also governor () for the Roman province of Moesia Superior.
The Roman army made Aemilianus emperor in Moesia in July or August 253. The Roman Senate agreed that Aemilianus was emperor after the emperor Trebonianus Gallus died in August 253.
After defeating the Goths (a barbarian tribe) in modern-day Bulgaria, his soldiers proclaimed him as an emperor instead of Trebonianus Gallus, the emperor at the time. After defeating Gallus in battle at Interamna (Northern Italy), he captured the capital city of the empire, Rome.
When the governor of Roman Germany, Valerianus, arrived in Italy bringing troops to help Trebonianus Gallus, Aemilianus's own troops killed Aemilianus. They did not want a civil war and Valerian had a bigger army than Aemilianus.
Soldiers in Aemilianus's army killed Aemilianus at Spoletum in the Italian Peninsula (Spoleto, Italy).
Aemilianus's wife was Cornelia Supera. She became "augusta" (empress) in around August 253. Cornelia Supera may have died in September or October 253, at which time the soldiers killed Aemilianus.
Afghanistan at the Olympics
Afghanistan at the Olympics is a history which includes 13 games in 12 countries and 100+ athletes. Since 1936, Afghanistan has contributed to the growth of the "Olympic Movement".
The International Olympic Committee's official abbreviation for Afghanistan is AFG.
The Afghanistan National Olympic Committee was formed in 1935. It was recognized by the International Olympic Committee in 1936.
Afghanistan's team first competed at the 1936 Summer Olympics in Berlin.
In 1999, Afghanistan was banned from the Olympics due to its discrimination against women under Taliban rule.
In the 2004 Summer Olympics two women, Robina Muqim Yaar and Friba Razayee, were the first women to compete for Afghanistan at the Olympics. Mehboba Ahdyar, a woman in the 2008 Summer Olympics had death threats because of her plan to be in the Games.
Hypodermic needle
A hypodermic needle is a hollow steel tube that is sharpened into a needle so it can be jabbed (inserted) into somebody's body. After it is in, medicine is pushed through the steel needle. The name "hypodermic" comes from two Greek words meaning "below skin".
Operant conditioning
Operant conditioning is a form of learning. In it, an individual changes its behaviour because of the consequences (results) of the behaviour.
The person or animal learns its behaviour has a consequence. That consequence may be
There are four different contexts in operant conditioning. Here, the terms 'positive' and 'negative' are not used in their basic sense; "positive" means that something is added, and negative means something is taken away:
The idea of operant conditioning was first discovered by Edward Thorndike, and analyzed by B.F. Skinner.
Operant conditioning is different from Pavlov's classical conditioning. Operant conditioning deals with the voluntary modification of behaviour; classical conditioning with training a reflex.
Operant conditioning, sometimes called "instrumental learning", was first studied by Edward L. Thorndike (1874–1949). He observed the behavior of cats trying to escape from home-made puzzle boxes. When first put in the boxes, cats took a long time to escape. With experience, successful responses occurred more frequently, enabling the cats to escape in less time. In his law of effect, Thorndike theorized that behaviours followed by satisfying consequences tend to be repeated, and those that produce unpleasant consequences are less likely to be repeated. In short, some consequences "strengthened" behavior and some consequences "weakened" behavior. Thorndike produced the first known learning curves by this procedure.
B.F. Skinner (1904–1990) worked out a more detailed analysis of operant conditioning. Skinner invented the "operant conditioning chamber" which let him measure rate of response as a key dependent variable. He used a record of lever presses or key pecks.
Principles of operant conditioning:
Atrax
Atrax is a genus of spiders. They have very strong venom. These spiders aggressively defend their territory and chase off attackers who may scare them by making a threat display. Next they will bite. The fastest death occurred in 1927 when a young boy died within fifteen minutes of being bitten. Thirteen deaths were recorded in the fifty years before antivenom was invented for this spider's bite. In English they are sometimes called Sydney Funnel Web spiders because they come from around that part of Australia.
Under the heading "spiders" (Aranae) there are three main groups. One is so very old that only a few species still live on earth. Another is the group that includes the spiders that can be seen making webs or chasing prey almost everywhere in the world. The third group includes the tarantulas and a few other kinds of spiders. The Atrax spiders belong to this third group.
There are also species called "funnel-web spiders" that belong to the second group mentioned above. So they are not close relatives of Atrax, and they are not dangerous. They just have a similar way of making a funnel-shaped web that leads down to some kind of shelter where the spider hides in wait for some insect to eat. Atrax is a very large and very aggressive spider, and these other spiders are from small to medium size and are extremely timid.
