...computer teacher at Garfield High School in downtown Los Angeles, California. To his surprise, the school lacked the computers he needed for the class, so he took an alternative position as a math teacher. In that first year of teaching, Mr. Escalante was confronted with many obstacles. The school was in the verge of loosing its operative certification; many students scored poorly in their academics, had problems with drugs or were involved in gang violence. As a new teacher, he constantly felt frustrated, with a sense of guilt for not inspiring his class to love math the way he did. Subsequently, and against all the odds, Mr. Escalante made a great contribution in the lives of students, and transformed the face of the College Board’s Advanced Placement Program® (AP®). Most...

Through the use of cookies during online navigation, users are “customizing” their use of the internet which allows them to have quicker and easier navigation (automatically fulfilled) This also allows providers to get a lot of information about customers Three main purposes of having records: * Customer Relationship Management * Targeted advertising * Geographic localization Question 3: What is the biggest concern most cell phone users have about using m-commerce services? What are some other...

...require remedial work. Advanced Placement Test (AP) High school students, who are high achievers, have an option to take AP classes. The College Board requires that the AP class be taken by an accredited school and the courses have to be approved and audited by the College Board. Only the approved sites are able to use the "AP" designator on the transcript "Authorization to use the "AP" designation for your course. http://www.collegeboard.com/html/apcourseaudit/faq.html However, a home school educator can create an account on the AP Course Audit homepage at the College Board website. Once the account is created, submit the course material and course syllabus to be evaluated and pre-approved. AP is graded on a simple 5-point scale. Each university has their own guideline of which AP classes to accept and what grade level is required. Before taking the AP course, check with the Universities for their rules. The point-scale for the AP exam ranges from 1 to 5. 5 - Exceptionally qualified to receive college credit 4 - Qualified to receive college credit 3 - Qualified to receive college credit, although a 3 is not accepted by most colleges. 2 - Could possibly be qualified to receive college credit (keep in mind that almost no college will accept a score of 2) 1 - Not recommended to receive college credit There are 37 AP courses offered each May around the country.

...progressively cheaper. Problems that Intel had (because of the September 11): - product delays - shortages (escassez) - recalls (devoluções) - overpricing (preços excessivos) - bugs in the systems (erros no Sistema) - advanced Micro Devices (competitor) had produced its Athlon processor chip (faster than Intel’s Pentium III chip) With these problems, analysts predict that Intel’s share of market would be 9% worse than 3 years later. Causes of BARRETT’S WITHDRAWALS: - The downturn (crise) in economic conditions; - Weak demand (fraca procura) and over-capacity (supercapacidade) – Fall in global sales of chips. BARRETT’S OBJECTIVES: - Reorganize Intel to make it more nimble (ágil), to avoid duplication, to create better coordination and to enable (possibilitar) decentralization and delegation of decision making. Another problem: (intern) The network operations group and the communications unit sometimes were in competition with each other, selling similar products to the same customers. BARRET’S REORGANIZATIONS DURING THE FIRST 3 YEARS: 1) He created a new wireless unit (1999); 2) He created the Architecture Group (2000); 3) He reorganized the Architecture Group and created a new unit consisting of a merger of communications and network operations (2001). Reorganization consequences: - “shuffling execs like cards in a deck”; - people moved around a lot without really knowing where they were going ( and costumers realize that); - Intel was “dabbling in...

...paper is to develop an efficient and cost effective method for Hard Disk Drive(HDD) Security. The task is implemented using Partial Disk Encryption (PDE) with Advanced Encryption Standards(AES) for data security of Personal Computers(PCS) and Laptops . The focus of this work is to authenticate and protect the content of HDD from illegal use. The proposed method is labeled as DiskTrust. FDE encrypts entire content or a single volume on your disk. Symmetric key uses same key for encryption as well for decryption. DiskTrust uses these two technology to build cost effective solution for small scale applications. Finally, the applicability of these methodologies for HDD security will be evaluated on a set of data files with different key sizes. KEYWORDS- INFORMATION SECURITY, INTEGRITY, CONFIDENTIALITY, AUTHENTICATION, ENCRYPTION. I. INTRODUCTION In today’s world information security is an important concern for every individual. People spend hundreds of dollars in protecting their data to stay in the competition, and any leakage of crucial data can result in unrecoverable loss. Information security is the most important form of security even before network security, as information stored securely can only be transmitted securely over a network, there by stating the importance of information security over network security. However, along with the convenience and easy access to information come risks. Among them are the risks that valuable information will be...

...Television News Program Analysis Assignment Darris Simmons Com/310 Dina Ginsberg 10/13/2011 Television News Program Analysis The story I chose to cover is on former hedge fund tycoon Raj Rajaratnam, a 54 year old founder of Galleon Group. He was convicted in May on conspiracy and fraud for persuading a crew of corporate insiders to provide him with illegal tips on technology stocks. These tips earned him between $70- $75 million in profits for his. These stock tips include tech companies such as Sun Microsystems, IBM and Advanced Micro Devices. The coverage by each news source was pretty parallel except a few deviations from the main point of the story. Some similarities of the casts were, the number of people charged in the case, they also focused on the health of Rajaratnam. They drove in the fact that his health was deteriorating and that could be why his sentence was only 11 years versus the I saw the story as subjective because they focused mainly on facts other than the views express years the US government sought out for in the beginning of the trial in May. The focus on that could persuay the feelings of the viewer because the media knows viewers are sensitive to things such as health. Although they brought health to the table they immediately did a 180 degree turn and showed this quote, "His crimes and the scope of his crimes reflect a virus in our business culture that needs to be eradicated," by judge Holwell. They used this quote in two of the three news...
