Define activity-based costing (ABC) systems. What benefits does implementing an ABC system bring to a company? Explain at least two benefits. What are the disadvantages of implementing an ABC system? List and explain at least two. Would the proposed changes make ABC a universally applicable costing method in your opinion? Why or why not? Elaborate your response.

Consider a galvanic cell based on the following line notation at standard conditions and 298K:

Sn | Sn²⁺ || Fe³⁺ | Fe

Which of the following changes WILL NOT change the potential of the cell?
Add equal amounts of water to each half cell
Replace the Fe electrode with a Pt electrode
Increase the concentration of Sn²⁺
Decrease the concentration of Fe³⁺
Replace the Sn electrode with a Pt electrod

Which of the following is not a feature of the “torpedo” model for transcription termination in eukaryotic cells?

Do pesticides even at a non-toxic dose bioaccumulate in animal and plant tissue?

Also do metabolite changes in plants for herbivore defense causes similar fluctations in p450 expression? the sub-lethal stress (ie parasites, pathogens and habitat loss) may change expression. Does exposure to this growing list of factors detract from pesticide defense by p450?

Why has the United Nations been unable to become a world government? What aspects of its organization and form make it impossible/difficult? What aspects of it seem like a world government? What would have to change in its organization or the way the world likes at it to make it a world government? What stops it, if anything, from making those changes?  

Phenology Climate Shifts and ecological consequences. What evidence do we have that plant flowering dates are changing? What is the problem with changes is phenology? Does there seem to be a link with changing or not changing and species decline? Are all groups of plants affected equally? Around Concord, MA what other factors may be confounding influences on local plant diversity?  

Donald Trump promised a more aggressive fiscal policy with a large increase in spending and significant tax cuts leading to a much larger government (budget) deficit. The US economy was at near the full employment (the unemployment rate in the US was low below 5%), what do you expect will be the response of the US Central Bank in terms of changes to the cash rate? Explain.

Suppose that the government of an economy that is in its long-run equilibrium gives out money to most of the residents. Using the IS-LM and AS-AD model, describe both the short-run effects and the long-run effects of the following changes on national income, the interest rate, the price level, consumption, investment, and real money balances. Make sure to use both words and figures.

In general, do not use any derivative rules ( as power rule, etc.). Find the derivative of the following functions at the point "a" by computing average rate of changes for h = ±1, ±0.1, ±0.01, ±0.001, ±0.0001 :

a.) f(x) = x² + x³ , a = 1

b.) f(x) = x ²+ x³ , a = 3

c.)  . f(x) = x − x² , a = 2

Please select one post acute setting and do some research on the patient population, services they provide, LOS, reasoning for patient admission. Then search for one article within the past 2 years regarding your post acute setting and their reimbursement (it can be regarding payment models, fraud and abuse, cost changes etc). Include the link to you article.
