The relationship between technology and society is characterized by feedback. Technological determinists and social determinists perspectives are offer informative but narrow insights into either side of the process. Innovative individuals can generate new technologies that alter the lives, practices, and even ways of thinking in a society. Societies alter technologies as they adopt them, often...

Service quality and patient satisfaction affect an organization's value-based payments. This new value paradigm calls for a new approach to service education and training for front-line staff. Thoughtfully conceived, department-specific content, infused with patient feedback, value creation, and science of service quality principles, was developed to give front-line staff a deeper understanding...

In this paper, a novel approach for control of the DC-DC buck converter in high-power and low-voltage applications is proposed. Designed method is developed according to state feedback linearization based controller , which is able to stabilize output voltage in a wide range of operation. It is clear that in high-power applications, parasitic elements of the converter may become comparable with...

Feedback is a very powerful concept and has numerous applications. Examples of feedback systems abound in everyday life. For example, the thermostat on an air conditioner unit uses feedback to maintain a comfortable temperature within a room. Similiarly, our bodies use feedback to increase antibodies to fight off an infection. By definition, feedback is the process of combining the output of a ...

the first enzyme of the pathway for uridine diphosphate n-acetyl-d-glucosamine (udpag) biosynthesis i.e. l-glutamine: d-fructose 6-p amidotransferase (e.c. 2.6.1.16) was purified 52-fold from human placenta using methanol fractionation and column chromatography on deae-sephadex a-50. the enzyme showed optimal activity in a broad range of ph from 5.8 to 7.8 in both phosphate and cacodylate buffe...

It has been shown that the rostral cingulate zone (RCZ) in humans uses both positive and negative feedback to evaluate performance and to flexibly adjust behaviour. Less is known on how the feedback types are processed by the RCZ and other prefrontal brain areas, when feedback can only be used to evaluate performance, but cannot be used to adjust behaviour. The present fMRI study aimed at inves...

Feedback processing is an important aspect of cognitive control and decision-making. Several studies have shown that heart rate slows following feedback that indicates incorrect performance or loss of money. The current study was the first to investigate (1) whether this slowing reflects an evaluation of the valence of the outcome or a system that indicates that the feedback contains informativ...
