  • For the following 700 years, shoguns from a succession of clans ruled in Japan, while the imperial court existed in relative obscurity.
  • Suspicious of Christianity and of Portuguese support of a local Japanese revolt, the shoguns of the Tokugawa period (1603–1867) prohibited all trade with foreign countries; only a Dutch trading post at Nagasaki was permitted.

  • The U.S. and Japan signed a security treaty in 1951, allowing for U.S. troops to be stationed in Japan. In 1952, Japan regained full sovereignty, and, in 1972, the U.S. returned to Japan the Ryuku Islands, including Okinawa.
  • A shrewd trade policy gave Japan larger shares in many Western markets, an imbalance that caused some tensions with the U.S.

    • Minjie Kim
       
      basically, the more you "reinforce" the faster the response will take to become a habit.
  • the longer the interval, the greater the number of intervening responses emitted without reinforcement. The resulting extinction cancels the effect of an occasional reinforcement.
    • Minjie Kim
       
      the less you reinforce, the more the habit will be lost. like how with some things (like art or a sport) you need to keep practicing to be good at it. If you quit practicing altogether, you'll lose your ability to do whatever it is. That's basically what extinction is.

Dead dog as art - Opinion - 0 views

  • When asked to provide an explanation for his actions Vargas claimed that this so called "art exhibit" was his way of paying respect to his friend who had died recently after he was attacked by two Rottweilers guarding a shop which his friend had been burglarizing.Upon reading through a few of the comments and blogs, I found that there were several threats against the artist, saying that he should be tortured and allowed to die just as the dog. However, no one mentions anything about the spectators. I am in no way defending Vargas's actions, I am however disgusted at the idea that no one attempted to rescue the dog. Pictures show people standing close enough to get a good look yet far enough away to escape any responsibility for the suffering the dog was clearly enduring. The stray dog is more alive today then he was the day he stood as a spectacle of suffering and selfishness. This story has gotten the attention of people everywhere, and rightfully so

List of breakdance moves - Wikipedia, the free encyclopedia - 0 views

  • The Top Rock is a combination of steps done while standing up. This is the entry dance that Bboys and Bgirls use to start their set. These steps are done before you do a power set or before you go down to the floor. This is the breaker's chance to show how well he or she can rock the beat and/or make gestures to intimidate their opponent
  • The foundational footwork sequence. Although many variations exist that either add or subtract steps in the sequence, the 6-step is the most basic form of downrock.
  • A Power Move is any type of move in Bboying which requires spinning and/or rotating in a way that can be done so in multiple rounds. All Power Moves (or series of a type of Power Move) can be connected in combos to form a "Power Combo". Breakers that use mostly Power combos in there sets are commonly known as "Power Heads". Example: Flare-Air Flare-Elbow Air Flare-Air Flare-1990...etc Or-Air Flare 1.5-Babymill-Windmill-Swipe-Windmill-Halo-Headspin...etc The possible number of combinations are endless and only limited by stamina, strength and imagination. In 2002 The Guinness Book of World Records began tracking number of power move rotations for their world record standings. At that time Canadian Gregory Burbidge broke records for Air Flare, Headspins, and Elbow Airflares. American Lauren Jacob held the record for Chair Flares. American Laura Derrick held the record for Tappingmills. Nicole Jones (nationality unknown) held the record for Munch Airflares. In 2004 Guinness removed these titles from their records. At the time Gregory Burbidge was the only one who still held records from the original group.

Chiroptera - 0 views

  • One unique feature of bats is their modified forelimbs, which support a wing membrane (patagium). The basic elements of the mammalian limb are present in bats, although the relative sizes of most bones and muscles differ from those of nonflying mammals. The most elongated parts of the limb are those of the hand (metacarpal bones) and fingers (phalanges). The primary functions of these bones in bats is to provide support for the patagium and control its movements.
  • Numerous blood vessels and nerves are present throughout the wing membrane. Bats also have five unique muscles present in the patagium, and use additional muscles in the chest and back to move the wings up and down.
  • The most obvious difference between bird wings and those of bats is that bird wings are made of feathers, not a skin membrane. Birds have an elongated arm, but do not have elongated fingers like bats. Additionally, the muscles used in both the upstroke and downstroke are found in the chest of birds, while the upstroke muscles are on the back in bats (Fenton, 1983).
  • ...7 more annotations...
  • The orientation of the hindlimb is also unique to bats. The hip joint is rotated 90° so that the legs project sideways and the knee faces almost backwards. Due in part to the rotation of the hindlimb, the walking motion of bats differs from other tetrapods, often appearing awkward. The hindlimb is designed to support the patagium in flight and allow the bat to roost hanging from its hindlimbs. Most bats have a tendon system in the toes that locks the claws in place so the bat can hang upside down even when asleep.
  • The body of a bat is ventrally compressed with a short neck region. The bones tend to be slender and light-weight. The majority of the body weight is concentrated in the chest region due to the large flight muscles.
  • The overall shape of the head varies more in bats than within most other groups of mammals. Some bats have very elongated muzzles while others have broad, short faces. There is a correlation between the shape of the head and the type of food eaten. For example, most nectar feeders have long, narrow muzzles that are good for reaching into flowers, while many fruit eaters have short, broad faces good for biting rounded fruits (Hill and Smith, 1984).
  • The ears range from small and round to large and pointed, and often have a cartilaginous fold (tragus) present at the notch of the ear. There is additional variation in the nasal and lip regions of bats. Some bats have complex noseleafs, folds, or wrinkles on their muzzles.
  • A major misconception about bats is that they are blind. This idea originated from the fact that bats are able to successfully maneuver in the dark and often have small eyes. While some bats do have very small eyes (most Microchiroptera) many have large and complex eyes (Megachiroptera).
  • Bats usually have black or brown fur, although the fur can also be gray, white, red, or orange. In some species there are stripes on the face or down the back, or patches of white on the face or above the shoulder. The length of the fur also varies among species from short and dense to long and fluffy. The wing membrane is usually dark in color, although it may have white on the tips or be a lighter color around the bones in the membrane. A few bats have white or pale yellow wings. There are also little hairs on the membrane itself. These hairs can be the color of the wing or the same color as the body.
  • The bat monophyly hypothesis states the Megachiroptera and Microchiroptera are each others closest relatives in an evolutionary sense (i.e., they form a clade).

How Thanksgiving Was Celebrated During The 17th Century - 0 views

  • It is usually said that in the year of 1621, in the colony of Plymouth, the English colonists and the Wampanoag Indians got together and shared a fantastic fall harvest banquet to celebrate the bounteousness from the fertile earth. Today this celebratory banquet is considered as one of the first Thanksgiving celebrations in the early days of the colonies. While this ancient celebration is regarded as the first Thanksgiving feast; it is simply one of the numerous celebrations of the harvest season and human thankfulness for the bounties of Mother nature. Indeed, many Native American groups such as Comanche, Cheyenne, Arapaho, etc. celebrated the end of the harvest season many centuries before the coming of the Europeans. These festivities included ceremonial dances, races, games and other celebrations of thankfulness.Long before the discovery of the American continent and the colonization by the Europeans, Native Americans, like Apache, Navajo, Huron, Iroquois, Sioux and many others, organized festivals at the end of the harvest

THANKSGIVING DAY - Why do Americans celebrate it? - Kid Explorers - 0 views

  • We can trace this historic American Christian tradition to the year 1623. After the harvest crops were gathered in November 1623, Governor William Bradford of the 1620 Pilgrim Colony, "Plymouth Plantation" in Plymouth, Massachusetts proclaimed: "All ye Pilgrims with your wives and little ones, do gather at the Meeting House, on the hill… there to listen to the pastor, and render Thanksgiving to the Almighty God for all His blessings."
  • Thursday, the 19th day of February, 1795 was thus set aside by George Washington as a National Day of Thanksgiving. Many years later, on October 3, 1863, Abraham Lincoln proclaimed, by Act of Congress, an annual National Day of Thanksgiving "on the last Thursday of November, as a day of Thanksgiving and Praise to our beneficent Father who dwelleth in the heavens." In this Thanksgiving proclamation, our 16th President says that it is…
  • So it is that on Thanksgiving Day each year, Americans give thanks to Almighty God for all His blessings and mercies toward us throughout the year.

Student Research Center - powered by EBSCOhost: Pilgrim's paradox - 0 views

  • he Pilgrims, fleeing religious persecution, sailed from England to the New World aboard the Mayflower. They stepped ashore on Plymouth Rock and began a new colony. In unfamiliar territory, they came near starvation, but the Indian Squanto appeared and taught them to plant corn and make their living from the land. Led by William Bradford and Miles Standish, they survived these difficult early days, and when they brought in the first rich harvest, they set aside a day to give thanks to God for their good fortune. The chief Massasoit and their other Native American neighbors came bringing deer and wild turkeys, and together the Indians and the Pilgrims celebrated the first Thanksgiving. The vague history (more myth, really) of the first Thanksgiving presents a scenario of the encounter of New World and Old World people that existed for only a moment, if it existed at all. It involves one of the least typical, and least successful, groups of European colonizers of the North American continent. Yet Thanksgiving is an important celebration throughout the United States, and like most things central to American culture, it is complicated and multilayered.

  • Small and furry, bats are the only mammals to have achieved powered flight.
  • Their arms are spindly, with membranes stretched between the fingers on each hand.
  • Despite their resemblance to rodents, bats are not closely related to mice at all. Though their exact placement is still uncertain, there is recent evidence that they may be more closely related to the primates.
