...MBA Integrative Project BUS599 Module 1 Strategic Review Skype FOR Dr. Harry Hascall From: William E. Lopez-Valentin Date: Jul 23, 2012 Trident University Strategic Analysis of Skype Introduction This paper will present a strategic analysis of Skype. I will discuss Skype Mission, Vision, Values, Goals / Objectives and strategic business. Skype was founded in Luxembourg in 2003, by Niklas Zennstrom and Janus Friis, creators of Kazaa, software designed to share music and movies. Throughout its history, framed by investment offers and sales of the company, Skype remains a large and prized signature in the world of technology. In 2005, eBay the product auction site through internet bought Skype for 2.6 billion dollars. Before the end of that year, the company introduced one of its flagship services: video calling. In 2006, Skype reached 100 million users worldwide. In the same year, it released version 3.0 of its software for Windows and 2.0 for Mac. From conception to acquisition Since in the changing world of technology everything cannot be 'rosy', in 2008 Skype began to have conflicts with eBay. On the one hand, the service implemented to enhance communication between buyers and sellers in the online auction service; was not leaving the desired results. On the other hand, the old system developers sued eBay for licenses used had expired. In 2009, eBay ended up selling 70% of Skype for 2.7 billion dollars to the group Silver Lake...

...MHM502 Case Study Module 1 Health Care Finance 12 June 2015 Identify the distribution of national health spending by type of financing source. Identify the distribution of health insurance coverage among the U.S. population. Discuss the impact of the Patient Protection and Affordable Care Act and the difficulties that might be encountered by those mandated to participate. Discuss the origin of employment-based health insurance. Explain the difference between fully insured and self-insured health plans. In the most recent survey identified, the distribution of national health spending for calendar year 2002 it was noted that the public sector accounted for 56.1 percent of health spending within the civilian noninstitutionalized population. Public spending on health care among the civilian, noninstitutionalized population averaged $2,612 per person (2002 dollars). Tax subsidies averaged $745 per person. Public spending averaged more than half of total health spending. Age, sex, and race/ethnicity. Public spending was strongly related to age. Children age eighteen or under received $1,225 of public spending apiece, on average, which was less than one-fifth of average public spending for seniors ($6,921). This is not surprising, given that total expenditures rise with age. What is more interesting is that public spending as a share of total spending was ten percentage points higher for seniors than for children, despite much-publicized expansions in children's eligibility...

...A. Rounding and Truncation A1-A2. To determine if Student 1 will receive an A, we must first calculate the percentage. Divide the total points earned by the total points possible. THis gives us a solution of .895 or 89.5%. Next we round up to the nearest whole number. When rounding, we focus on the digit to the right of the digit we are trying to round. If it is 5 or greater, we round up by adding one. If it is less than 5, then we leave the digit alone. 89.5% rounds up to 90%. Student 1 will receive an A. If the teacher were truncate the grade, then the student would not receive an A. He/she would only have a 89% because we drop all digits to the right of the digit to be truncated. A3a. A taxpayer would hope for the tax rate to be truncated because they would owe less taxes. You are basically erasing everything behind the decimal with truncation. Thus the resulting number will always be smaller. This is ideal especially whenever dealing money owed. In this case the taxpayer would have a tax rate of 27%. A3b. The government obviously prefers taxpayers to round, due to the possibility of a higher tax rate. If the digit to the right of the digit to be rounded is 5 or greater, then we add a 1 when rounding. So in this example the tax rate would increase to 28%. Let’s say the taxpayer makes $80,000 a year. The government would be due an extra $800. Now if you multiply this by several taxpayers, and it’s evident how much more the government will benefit from simply rounding...

...encryption method we get the following steps: 1. Two prime numbers p = 11 and q = 7 2. Compute n = pq and z = (p – 1)(q – 1) 3. n = pq = (11)(7) = 77 4. z = ( p – 1 )( q – 1 ) = ( 11 – 1)( 7 – 1) = (10)(6) = 60 5. Choose a number e < n such that it has no common factors with z other than 1 6. So here we are choosing k = 7 7. Thus, the encrypted value c of the plain text message m is: 8. c = me mod n Now, using the alphabet such that the letters are numbered 1 through 26 we get Plain Text | h | e | l | l | o | Number | 8 | 5 | 12 | 12 | 15 | Encrypted value | 8 | 10 | 17 | 17 | 15 | Plain Text: h e l l o Number: 8 5 12 12 15 Where, 87 mod 77 = 57 57 mod 77 = 47 127 mod 77 = 12 127 mod 77 = 12 157 mod 77 = 71 Encrypted value 57 47 12 12 71 SOLUTION: This gives the encrypted value of the word “hello” as 57 47 12 12 71 DECRYPTION: Using the RSA Decryption method we get the following steps: 1. Find a number d such that ed divided z has a remainder of 1 2. Using the extended Euclidean algorithm to find the inverse modulo 35 3. We get d = 43 4. The public key becomes K+B or the number pair (n, e) and the private key becomes K-B or the number pair (n, d) In order to decrypt the message c, calculate: m = cd mod n Thus, we get: Encrypted value 57 47 12 12 71 Where 5743 mod 77 = 8 47743mod 77 = 5 1243 mod 77 = 12 1243 mod 77 = 12 7143 mod 77 = 15 Encrypted Number: 8 5 12 12 15 ...

...Front Office Management 1 Front Office Operations & Service 1 Non-verbal communication is often subtle and can include body language, tone of voice, and gestures so in this case, Drew – a bell attendant gave an audible sign and muttered loudly about amount of tips. When the guests came into the lobby, he was standing and leaning against the front desk - in the place where no one can see him. After guest’s check in, they needed the assistance and at that time Drew just walked away. He heard the radio call him and he ignored the cue from MOD. He went to find Jim, the second bell attendant. When Jim interacts with guest waiting for the luggage, the main problem will be for him, is that the atmosphere the attitude he created and the mood he destroyed by making guest’s wait. All the bell attendants act like they are bosses. They only work for the tips, however in the contract they already have the 15% tips on every room charge whether guests used service or not. The bell attendant is usually the first representative of the establishment who meets face-to-face with the guest and this meeting can therefore have a lasting impression. The moment the bell attendant identifies a guest; they should immediately acknowledge them and not wait for the guest to make the first move and not wait to ask. When guests arrive the bell attendant should welcome them warmly, the establishment may have a protocol for greeting guests. As part of the greeting, offer assistance to guests. Check...

...1. Illustrate the operation of Radix_sort on the following list of English words: cow, dog, seq, rug, row, mob, box tab, bar ear, tar, dig, big, tea, now, fox. ANSWER: It is a sorting algorithm that is used to sort numbers. We sort numbers from least significant digit to most significant digit. In the following array of words, three is the maximum number of digits a word has, hence the number of passes will be three. In pass 1, sort the words alphabetically using first letter from the right. For eg, tea has “a” as the last letter, hence it comes first, similarly mob which has “b” as the last letter comes second. In this way the remaining words are sorted. In pass 2, sort the words alphabetically using second letter from the right. For eg, tab has “a” as its middle letter which comes first, then comes bar and so on. In pass 3, sort the words alphabetically using third letter from the right. For eg, bar has “b” as its first letter from left and since no word starts with “a”, bar will appear first. Similarly, big, box, cow and so on. UNSORTED ARRAY | PASS 1 | PASS 2 | PASS 3(SORTED ARRAY) | cow | tea | tab | bar | dog | mob | bar | big | seq | tab | ear | box | rug | rug | tar | cow | row | dog | tea | dig | mob | dig | seq | dog | box | big | dig | ear | tab | seq | big | fox | bar | bar | mob | mob | ear | ear | dog | now | tar | tar | cow | row | dig | cow | row | rug | ...

...LOGICAL INFERENCE & PROOFs Debdeep Mukhopadhyay Dept of CSE, IIT Madras Defn • A theorem is a mathematical assertion which can be shown to be true. A proof is an argument which establishes the truth of a theorem. Nature & Importance of Proofs • In mathematics, a proof is: – a correct (well-reasoned, logically valid) and complete (clear, detailed) argument that rigorously & undeniably establishes the truth of a mathematical statement. • Why must the argument be correct & complete? – Correctness prevents us from fooling ourselves. – Completeness allows anyone to verify the result. • In this course (& throughout mathematics), a very high standard for correctness and completeness of proofs is demanded!! Overview • Methods of mathematical argument (i.e., proof methods) can be formalized in terms of rules of logical inference. • Mathematical proofs can themselves be represented formally as discrete structures. • We will review both correct & fallacious inference rules, & several proof methods. Applications of Proofs • An exercise in clear communication of logical arguments in any area of study. • The fundamental activity of mathematics is the discovery and elucidation, through proofs, of interesting new theorems. • Theorem-proving has applications in program verification, computer security, automated reasoning systems, etc. • Proving a theorem allows us to rely upon on its correctness even in the most critical scenarios.

...1. Introduction Initially, the encryption of message was based on symmetric key cryptography where sender and receiver of message use the same key for encryption and decryption.But, to use the same key, sender and receiver must share the key in advance. And if their locations are different than there is risk in transmission of the key. Later in 1976,a cryprosystem,which is known as Diffie-hellman key-exchange, was published by Whitefield Diffie and Martin Hellman and concept behind the cryptosystem is known as public key encryption. In public key cryptosystem, each one gets a pair of keys, public key and private key. The pubic key is freely available to everyone while the private key remains secret. The sender, who wants to send a message securely to someone, use public key of receiver to encrypt the message and receiver use his private key to decrypt the message.This system doesn’t require secure key transmission.So, it resolves the one of the problem faced by symmetric key cryptosystem. If someone is able to compute respective private key from a given public key, then this system is no more secure. So, Public key cryptosystem requires that calculation of respective private key is computationally impossible from given public key. In most of the Public key cryptosystem, private key is related to public key via Discrete Logarithm. Examples are Diffie-Hellman Key Exchange, Digital Signature Algorithm (DSA), Elgamal which are based on DLP in finite multiplicative group. 1 2. Discrete...
