Poverty in Canada.

Poverty in Canada. Poverty is a reality in Canada today. Despite having one of the higheststandards of living among all the developed nations, and despite being voted numerous times in recent years by the United Nations as the best country in the world in which to live, experts agree that poverty is prevalent in Canada today. Unfortunately, that is more or less where the agreement ends. Exactly how prevalent and how serious a problem poverty is in Canada is an open question that has been hotly debated for the last 10 years.There have been two times in the past 300 years when economic structural changes have occurred in the world that have been so massive and so far-reaching, that the impact on societies has been nothing short of monumental.The first time was in the Industrial Revolution which began in the early 1700s and caused massive societal transformations, especially in the western world, changing life from agrarian-based societies to industrial-based societies.POVERTYThe second time was in the ea rly 1980s with the beginning of the "Information Revolution." Today, a rapid, world-wide, economic transformation is taking place that is changing our societies from industrial-based societies to information-based societies, the 3rd wave.These changes are part of a greater phenomenon called "globalization" . The improvement in technology lead to a desire to make trades with other countries, and therefore allowing foreign companies to sell in Canada and thereby compete with Canadian companies, and vice versa ("Laisser faire, laisser passer" - Adam Smith).This increased competition lead to ever greater pressures on Canadian companies to reduce their costs of producing goods. Companies closed down and went looking in third world countries because labour is cheaper. At the same time, technology was replacing human labour; employees lost their jobs, being replaced by machines that could do the...

A Brief History of Prosthetics

A Brief History of Prosthetics The history of prosthetics and amputation surgery begins at the very dawning of human medicine. In the three great western civilizations of Egypt, Greece and Rome, the first true rehabilitation aids recognized as prostheses were made. Early use of prosthetics goes back to at least the fifth Egyptian Dynasty that reigned between 2750 to 2625 B.C. The oldest known splint was unearthed by archaeologists from that period. But the earliest known written reference to an artificial limb was made around 500 B.C. During the time, Herodotus wrote of a prisoner who escaped from his chains by cutting off his foot, which he later replaced with a wooden substitute. An artificial limb dating from 300 B.C., was a copper and wood leg that was unearthed at Capri, Italy in 1858. In 1529, French surgeon  Ambroise Pare  (1510-1590) introduced amputation as a lifesaving measure in medicine. Soon after, Pare started developing prosthetic limbs in a scientific manner. And in 1863, Dubois L Parmelee of New York City made a significant improvement to the attachment of artificial limbs by fastening a body socket to the limb with atmospheric pressure. While he was not the first person to do so, he was the first to make it practical enough to be used in medical practices. In 1898, a doctor named Vanghetti came up with an artificial limb that could move through muscle contraction. It wasn’t until the middle of the 20th century that major advancements were made in the attachment of lower limbs. In 1945, the National Academy of Sciences established the Artificial Limb Program as a way to improve the quality of life of World War II veterans who suffered the lost of limbs in combat. A year later, researchers at the University of California at Berkeley developed a suction sock for the above-knee prosthesis. Fast forward to 1975 and  the year an inventor named Ysidro M. Martinez took things a major step further by creating a below-the-knee prosthesis that avoided some of the problems associated with conventional artificial limbs. Instead of replicating the natural limb with articulated joints in the ankle or foot which tended to lead to poor gait, Martinez, an amputee himself, took a theoretical approach in his design. His prosthesis relies on a high center of mass and is light in weight to facilitate acceleration and deceleration and reduce friction. The foot is also considerably shorter to control acceleration forces, further reducing the friction and pressure. New advances to keep an eye involve the growing use of 3-D printing, which has allowed for the fast, precise manufacturing of artificial limbs that traditionally have been custom-built by hand. The U.S. government’s National Institutes of Health has recently established the 3D Print Exchange program as a way to provide researchers and students with the necessary modeling and software tools to fabricate prosthetics using 3D printing machines.   But beyond prosthetic limbs, here’s another fun fact: Pare could also have laid claim to be the father of facial prosthetics, making artificial eyes from enameled gold, silver, porcelain and glass. Thats your fun fact of the day
