Some medical procedures have been characterized as "halfway technologies", while at least some are close to being completely effective. what accounts for the difference? what "halfway technologies" of the past have become much more effective today? why has this advance occurred?

In the health care world, there are three levels of health care and one of them is known as "halfway technologies". Halfway technology is a term which Lewis Thomas used to  describe an obviously unsatisfactory situation that is still  the best available choice. These technologies include methods or therapies which do not get rid of diseases but at least postpone their effects. For example, the iron lung was a a typical halfway technology. It was definitely an improvement for those suffereing from lung diseases but it wasn't even close to offer a serious solution.  

Nowadays, just like in most fields, technology has gained a key role in the health of most human beings. Organ transplantation is a great example of how a "halfway technology" from the past took a step forward saving thousands of lives all throughout the world.  The explanation of why this advance has occured could be justified with the technical change in medicine and the advances in the biological sciences.

the anti federalists was a movement that was opposed to the creation of a us federal government. although they were not as organized as the federalists, they also had a large group of leaders, especially in state politics.

the statement "now, in a large extended country, it is impossible to have a representation, possessing the sentiments, and of integrity, to declare the minds of the people” represents the concerns of the anti federalists.

they strongly believed that the federalists were representing the interests of aristocratic elements of society at the expense of the majority of ordinary people, who lived in a rural society.

their fear for the creation of a strong federal government and the president’s power of veto in their opinion would create a tyrannical rule that would dominate the people. they defended the importance of restraining the government’s power towards people at any cost.
