Societal Dimension of IPE Solution International political economy was the original term used for studying problems that arise from or are affected by the interaction of international politics, international economics, and different social systems and societal groups. IPE has four dimensions :- security, production, finance,and knowledge. Political institutions are important determinants of these economic outcomes. In turn, the state of the economy affects political outcomes, both in the long run and in the short. Economic development affects the evolution of institutions and short run economic conditions affect political change and elections. We will interpret \"political institutions\" in a broad sense and we will also be interested in related issues such as the role and evolution of legal and administrative institutions, and issues concerning social interactions. The group focuses both on developed and developing economies and both on \"macroeconomic\" and \"microeconomic\" issues including international trade and international relations. International political economy relations cannot be completely controlled / predictable, these generally effects negative of IPs are primarily due to export subsidies and non-tariff barriers, particularly in less-developed countries. .

Show that the worst-case time complexity for Binary Search is given by when n is not restricted to being a power of 2. Hint: First show that the recurrence equation for W(n) is given by T(1) = 1 To do this, consider even and odd values of n separately. Then use induction to solve the recurrence equation. I understand how to find this with base 2 but totally lost otherwise? Solution Hi there, The time to search in an array of N elements is equal to the time to search in an array of N/2 elements plus 1 comparison. T(N) = T(N/2) + 1 Now we re-write the function in recurrence. T(N) = T(N/2) + 1 T(N/2) = T(N/4) + 1 T(N/4) = T(N/8) + 1 â€¦â€¦ T(4) = T(2) + 1 T(2) = T(1) + 1 Next we sum up the left and the right sides of the equations above: T(N) + T(N/2) + T(N/4) + T(N/8) + â€¦ +T(2) = T(N/2) + T(N/4) + T(N/8) + â€¦ +T(2) + T(1) + (1 + 1 + â€¦ + 1) The number of 1â€™s on the right side is LogN Finally, we cross the equal terms on the opposite sides and simplify the remaining sum on the right side, we get, T(N) = T(1) + LogN T(N) = 1 + LogN as T(1)=1 The worst case time complexityof binary search is: T(N) = O(LogN) .

Since Linux is an international operating system you can configure it to support a specific region. Discuss how you can configure its character set, keyboard layout, and date/time display formats for a specific region (or country) of your choice. Solution Region specific settings: Keyboard Layout: This is set using the loadkeys command.The local X configuation tool can be used for this purpose. XkbdLayout is the one that is used. Example: XkbdLayout \"us\" Fonts:The setfont tool is used for loading fonts in text mode.This usually comes with an innputrc file which enables the ability to combine characters. Example: export INPUTRC=\"/etc/inputrc\" Date and time display: This is usually done during installation.And then it can be updated using the Network Time Protocol. Example: debby: ^ > ps -ef | gre ntpd ntp 22458 1 0 2006? 00:00:24 ntpd -U ntp The ntp update is run manually in order to set the time every time we aproach the time server. root@box: ^ # ntpdate 12.2.4.100 15 Aug 15:35:43 ntpdate[20336]: adjust time server 12.2.4.100 offset -0.004567 sec NTP package can be checked in the given system manual.And the commands used for setting the correct time zone are tzconfig or timezone commands. Language : gdm or kdm commands are used to configure language settings before logigng in. Example: debby: ^> acroread/ var/ tmp /54743s.pdf Warning: charset \"UTF-8\" not supported,using \"ISO77695-1\".

Case: The Long, Loud Silence Background As the director of health information services recently hired from another organization, it did not take you long to discover that morale in the department had been at a low ebb for quite some time. As you undertook to become acquainted with each of your employees, you quickly became inundated with complaints and other evidences of discontent. Most of the complaints concerned problems with administration, the financial division, and the records-related practices of physicians, but there were also a few complaints by staff about other members of the department and a couple of thinly veiled charges concerning health information services personnel who Solution 1. Such behavior of employees might be the result of psychological factors including fear, mistrust, or indifference . To cope with this issue, the manger should gain the confidence of employees. Besides this, he should encourage them to share their problems in the group meetings. He should assure them that their problems would be adhered and addressed by the managers. 2. Managers should conduct a face to face meeting with the employees carrying tales to the other departments . He should try to analyze their viewpoints and address their issues. They should be barred from such practices. The manager should suggest him to share his viewpoint in the team meeting or with his immediate supervisor. Even then, if the employees would not adhere to the managers, strict actions should be taken against them as their behavior might create huge conflicts in future. 3. This departmentâ€™s problems can be addressed with the help of following means of communication: .

Case 4.3 The Baptist Foundation of Arizona: The Whistleblower Hotline Consult Paragraph 5 of PCAOB Auditing Standard No. 10. Do you believe the Arthur Andersen auditors responded appropriately to the information received from BFA\'s former accountant, Karen Paetz? Why or why not? Solution Answer: Arthur Andersen auditors did not at all responded appropriately to the information received from BFA\'s former accountant, Karen Paetz! Beacuse, it is the fundamental duty of an auditor to bring all such concerns to the audit committee. It is unusual and unethical on the part of Andersen that he chose to completely ignore this individualâ€™s warning. Karen Paetz was employed by BFA for 7 years. Infact, she was a credible individual with a lot of knowledge of the accounting infrastructure at BFA. During Paetzâ€™s employment at BFA, she interacted frequently with Arthur Andersenâ€™s auditors on each audit engagement. The fact that she first resigned and then set up a lunch meeting with McGrath to voice her concerns ALOâ€™s deficit (in excess of $100 million) and ALOâ€™s monthly losses (approximately $2.5 million) underscored the importance of taking her concerns seriously. .

Case 5-1 David L. Miller: Portrait of a White-Collar Criminal There is an old saying: Crime doesn Solution Ans1) 1 st PART: Miller does seem to fit the profile of the average fraud criminal. This is because he worked his way up to gain inside information and trust from his bosses. He spent the money to support his lifestyle which was above his means. He also was not violent and he tried to use the money to pay back the stolen funds from his previous employers. 2 ND PART: He was different because he owned up to what he did and took responsibility for his actions. He tried to pay back the stolen funds and he truly believed he would be able to pay it all back. He was also different from the profile because even though he got caught and showed remorse he continued to steal. 3 rd PART: Miller was hard to detect because he was so well liked and trusted by his employers and fellow coworkers. Ans2) He was able to commit the fraud by being in a high ranking position that was able to avoid internal security around the company .

Carbon steel is an active metal meaning it has low corrosion resistance. Explain why it can be used to carry concentrated sulfuric acid (90 -95%) at room temperature (~ 25 C) which is a strong acid. 1.Predict what could happen if the system is open to atmosphere which has similar temperature (~25 C) and high humidity for a prolong period of time. 2.Describe possible corrosion forms of carbon steel exposed to concentrated sulfuric acid. 3. Corrosion rate of carbon steel in concentrated sulfuric acid initially decreases with liquid velocity, then after a critical velocity corrosion rate linearly increases. Explain why. Support your discussion with electrochemistry (thermodynamics and/or kinetics). Solution Corrosion is caused by moisture or water in the presence of acid. Concentrated sulphuric acid at that levels do not corrode carbon steel because presence of water in the solution is very less. 1. If the system is exposed to a high humidity environment for long times, it slowly starts to corrode because the amount of water becomes more. 2. The reaction product of corrosion are iron sulphate and hydrogen gas. The iron sulphate film is weak and can be disturbed by high acid velocities. CorossCoris also caused by hydrogen gas because it can take off mechanically weak iron sulphate film which is the only protection for the steel. 3. The corrosion reaction involves formation of iron sulphate and hydrogen. When liquid velocity is less, there are less amounts of hydrogen bubbles hitting the steel surface and they are uniformly carried. When the flow becomes turbulent, more bubbles hit the walls and scrape off the protective iron sulphate film which exposes the steel and there is an increase in corrosion. .

Carbon dioxide in the atmosphere traps heat from the sun and makes life on Earth possible. Why then should we be concerned about adding carbon dioxide to the atmosphere if it is a natural occurrence and beneficial to life on Earth? Solution Before the industrial revolution, Earth\'s atmosphere already contained CO 2 . CO 2 levels were regulated by the natural carbon cycle, where animals would breathe out carbondioxide and plants would absorb it to convert sunlight to energy and the oceans and soils would absorb and emit CO 2 . As human activities increased, we began burning various sources like oil,gas and coal for energy therby releasing additionalÂ Â CO 2 into the atmosphere. The extent of additional carbondioxide released into the atmosphere has been increasing day by day such that the natural carbon cycle is disturbed. Plants no more absorb all the huge excess ofÂ Â CO 2 released into the atmosphere. As a result, all theÂ Â excess CO2 in the atmosphere is trapping lot of energy in the form of heat from the Sun and this is the reason for global warming. Hence, natural occurance ofÂ Â CO 2 is beneficial to life on the Earth. However it has way back crossed the natural permissible levels and is hazardous to release more and moreÂ Â CO 2 into the atmosphere. .
