explain the phenomena of diffusion of responsibility and the problem of bystander apathy.

Fully explain the phenomena of diffusion of responsibility and the problem of bystander apathy. Then, knowing what these findings show, describe what you can do to maximize your chances of getting help if you are being physically attacked in a busy public park. How do you break through bystander apathy to get help?

Question

Theoretical and experimental measurements show that in many cases, the contributions of ionic and hydrogen-bonding interactions to ?H for protein folding are close to zero. Provide an explanation for this result. (Hint: Consider the environment in which protein folding occurs.)

The formation of favorable ______ ionic or ________ interactions in a _________ protein replace interactions between solvent (water) and the ionic species (or _________donors and acceptors) in the_________ state. The favorable ?H obtained by formation of ____________ bonds in the___________ protein is offset by the energy required to ___________ many interactions, with solvent going from the ________ to the ________ state.

Fill in the blanks above using the words listed below.

Web caching / Networks

Web caching / Networks

Question
We have all learned about web caching that
it reduces the average access time to the Internet. However, we may notice an increase in the access time for those requests that encounter a cache miss, because of the involvement of the cache. Let L is the LAN time, A is the access link time, I is the Internet time, and R is the total response time. Assume that P is the average cache penalty time, then
No cache:
R = L + A + I
Cache and hit:
R = L + P
Cache and miss:
R = L + P + A + I
Assume that L = 10 ms, A = 50 ms, I = 200 ms, and P = 35 ms.
(a) Find the average response time R when no cache is used?
(b) Find the average response time when a cache is used and the hit ratio is 90%?
(c) Find the average response time when a cache is used and the hit ratio is 10%?
(d) Find the hit ratio above which the use of cache is justified.
