#include<iostream>
using namespace std;
// class definition for asset
class Asset{
protected:
int value; // value of asset in cents
public:
Asset(int value); // constructor
int get_value(); // get the value
};
Asset::Asset(int val){ // implementation of constructor
value=val;
}
int Asset::get_value(){ // implementation of get_value
return value;
}
// abstract class for office equipment
class OfficeEquipment:public Asset{
public:
OfficeEquipment(int val); // constructor
virtual void use_item() =0; // not implemented here
};
// constructor
OfficeEquipment::OfficeEquipment(int val):Asset(val){

Asset* my_things[len];
// complete the code below
// (1)fill the assets up with 2 pens and two laptops (different values for each)
// (2)calculate the total value of all assets in my_things and print it out
// (3) call use_item on each of the items in my_things
}
The code in the main() function is incomplete. Write code as described in each of the comments marked (1), (2) and (3) above. Your code for (2) and (3) should take advantage of polymorphism to keep the code simple and short.

1.. On October 15th, a Congressional campaign orders a quantity of campaign literature from a local printer. The stated time of delivery is November 2 but there is nothing in the contract saying time is of the essence. November 8 is Election Day. The printer does not deliver the literature until November 9. When the bill arrives, the campaign refuses to pay the printer one cent. The printer contacts you and asks you to file a lawsuit to collect the bill. Explain to the printer what the legal issue is in the case? Apply the law and advise the printer of the best course of action (conclusion).
2.. Allen and Bob complete an oral contract for the sale of land from Allen to Bob for $100,000. Bob pays Allen the $100,000 and then begins to build a home on the land. At this point, Allen says that the deal is off and refuses to convey the deed to Bob. In doing so, Allen relies on the statute of frauds as a defense saying that contracts for the sale of land must be in writing and since this contract is not in writing it is unenforceable. First, explain the application of the statute of frauds to land sales. Second, state the legal issue, apply the law and reach a conclusion as to what will happen. Answer completely.
3.. Amy contracts to have her portrait painted by Herbert for $10,000. Herbert is a well known abstract artist and all of Amy’s friends have had their portrait painted by him. Herbert decides to go to Greece for the summer so he assigns the contract without talking to Amy, to Donald. Donald is another artist with a totally different style than Herbert. Amy is very upset when she finds out about the assignment and sues Herbert for breach of contract. What is the legal issue. Present both sides of the argument from a legal perspective. Reach a conclusion. What is a Judge going to do with Amy's lawsuit?

There have been some very nice discussions recently centered around the question of whether gravity and the geometry and topology of the classical world we see about us, could be phenomena which emerge in the low-energy limits of a more fundamental microscopic theory.
Among these, @Tim Van Beek's reply to the question on "How the topology of space [time] arises from more fundamental notions" contains the following description of the Reeh-Schlieder theorem:
It describes "action at a distance" in a mathematically precise way. According to the Reeh-Schlieder theorem there are correlations in the vacuum state between measurements at an arbitrary distance. The point is: The proof of the Reeh-Schlieder theorem is independent of any axiom describing causality, showing that quantum entanglement effects do not violate Einstein causality, and don't depend on the precise notion of causality. Therefore a change in spacetime topology in order to explain quantum entanglement effects won't work.
which is also preceded with an appropriate note of caution, saying that the above paragraph:
... describes an aspect of axiomatic quantum field theory which may become obsolete in the future with the development of a more complete theory.
I had a bias against AQFT as being too abstract an obtuse branch of study to be of any practical use. However, in light of the possibility (recently discussed on physics.SE) that classical geometry arises due to the entanglement between the degrees of freedom of some quantum many-body system (see Swingle's paper on Entanglement Renormalization and Holography) the content of the Rees-Schilder theorem begins to seem quite profound and far-sighted.
The question therefore is: Does the Rees-Schlieder theorem provide support for the idea of building space-time from quantum entanglement? or am I jumping the gun in presuming their is some connection between what the theorem says and the work of Vidal, Evenbly, Swingle and others on "holographic entanglement"?

Behavior Modification: An Alternative to Drug Therapy in
Treating Hyperactive Children ABSTRACT
The purpose of this study is to determine whether application of
behavior modification methods can be an effective and safe
alternative to amphetamine therapy in the treatment of hyperactive
school children. Sixty elementary age school children who were
identified as hyperactive were randomly assigned to one of three
treatment groups. It was concluded that additional research is
needed to determine the generalize ability of the findings to
larger groups and to non-special education classes.
In recent years, the use of amphetamines in treating hperactive
children, has caused much controversy and concern. According to
some researchers, an estimated 400,000 hyperactive school children
are presently being treated with these drugs. Much of the public’s
concern has to do with the way in which children are diagnosed.
Many children, for example, are being treated with amphetamines
solely on the recommendations of school authoritys. Despite the
fact that many teachers mistake the normal restlessness of
childhood for hyperkinesis. Anohter cause for concern stems from a
lack of follow-up studies on the long-term affects of
amphetamines.
As an alternative to drug therapy, researchers have begun to focus
on behavior modification techniques that are believed to be more
safer and more effective over time (Strong, 1974). Strong (1974)
conducted a two-year study with an autistic boy and found thast
positive reinforcement was significantly more effective than drug
therapy in reducing facial grimacing. In another study, this same
researcher found token reinforcement to be more effective then
medication in increasing adaptive behavior in retarded women.
Behavior modification techniques have also been studied in
classroom settings. Smith (1969), for example, was able to reduce
ina ppropriate classroom behavior of a ten-year old hyperactive
girl by using these techniques. In another study, Nixon (1969)
tested the effects of behavior modification in increasing the
“on-task performance” of 24 boys who had been diagnosed as
hyperactive by there teachers. In the Nixon (1969) study, their was
four treatment groups which consisted of various reinforcement
techniques and control. Results of a one-way analysis of variance
indicated no significant differences between the groups. Although
it was reported that some
of the children in each gorup made great improvement in staying on
task in learning situations. The Nixon study, however, contained
possible sources of error: (1) treatment groups only contained 6
subjects each; (2) there were only 8 treatment sessions;
(3) no instruments were used to evaluate children’s performance;
and (4) the children knew they were participating in a
study.Widespread use of amphetamines in treating hyperactive
children may be a dangerous practice. Moreover, behavior
modification techniques have shown to be just as effective in
reducing hperactive behavior in children in certain settings.
The sample group for this study will be selected from the
population of North Side Educational Center for behaviorally
disturbed, elementary-age children. Those children who were
diagnosed as “hyperactive” or “hyperkinetic” by the school’s
psychologist were cosnidered the population. The stratified random
sampling method is to be used to insure that children ages 6
through 12 were represented in the study.

Salem is a 15-year-old male weighing 46.6 kg. He is known to have asthma and. He accidently fell down and broke his leg while playing football. For that reason he was admitted to the hospital for surgery. Since he was 6 year-old, he presented to the emergency department many times and had 4 hospital admissions for asthma, two of them were to the intensive care unit. He often required a course of oral steroids for one month every few months. However, in the last two years his asthma was well controlled on fluticasone (inhaled steroid) and salbutamol (inhaled β-adrenergic agonist) and he didn’t need any oral steroids. Also, he had not visited the emergency department or been admitted to the hospital for the last two years.
On the day of the accident, the patient had no signs or symptoms of asthma. When he and his father were asked if he had tried aspirin or NSAIDs in the past they said they were not sure. When pain control was discussed, the father wanted to avoid morphine for its addictive effects. Consequently, the doctor prescribed him ibuprofen and planned to give him the first dose in the hospital under close observation soon after the surgery.
The surgery and anaesthesia went fine. One hour later, the patient was given a tablet of ibuprofen 400 mg orally for pain control. 10 minutes after that he began to show symptoms of asthma (shortness of breath and wheezing). For that he used his salbutamol inhaler 8 times. However, his symptoms became worse over the next 20 minutes and he was not able to talk. Soon after that, the patient became cyanosed and needed oxygen by face mask. Salbutamol inhaler was repeated and Hydrocortisone 100mg IV was given. Within 20–30 minutes his condition started to improve. Salbutamol was given every 4 hours and oral Prednisolone 50 mg once daily was initiated (for 6 days). To control the pain of his surgery he was given Morphine 5mg/4h orally and was observed closely overnight for the symptoms of asthma. He was discharged after one week. That week Salem didn’t experience any further asthma symptoms and returned home on his usual inhalers.
1. What is the most likely explanation (at the biochemical level) for Salem’s symptoms that developed after he was given the oral ibuprofen?
2. How do you explain the successful relief of the patient’s ibuprofen-induced symptoms after he was treated with hydrocortisone and prednisolone?
3. In this case study, β-adrenergic agonist and steroids were used to treat and/or prevent asthma symptoms. Mention the other two medication types useful in the treatment of asthma that are mentioned in eicosanoids metabolism chapter of your course. (0.5 mark for each medication type (1 mark total))
