Critical thinking case study - Essay Example 1. Assumes that the new product would help in restoring the old glorious status of AcuScan in the market. 2. Pat assumes that in order to thwart competition, the product must be announced and deployed within eight months 3. Assumes Secur-A Corporation is looking into this new retail opportunity and will come up with "some kind" of retail application in few months time. 4. Assumes that if others disagree with her that means they are not committed to the project and are trying to hamper the progress of the new product. 5. Assumes that producing a new product by August will not be difficult since AcuScan already has iScanner that can help in building the new product faster. 6. Predicts little investment on the part of staff's time and energy, which was one of the concerns, cited by Kelly. 7. Pat is looking for bringing out a new product in the market even if its not high quality for she feels that it's better to be first in the market than being high on quality. 8. Assumed customers would love the new product and actually felt they would be thrilled no matter what the product was. 9. Assumed I was "nit-picking" when tried to gather information. 10. Assumed project could be lent to outside contractors so that it would be finished on time. 11. Sees herself as a leader and a visionary and thus she must communicate her "dream" to everyone else. Chris Martinas - Vice President of Product Development 1. Agrees with Pat on some of her assumptions. a. Secure-A Corporation may come out with a product soon. b. Like Pat, Chris also sees minimal investment of existing staff's time since new product is a modified version of the existing old product. c. Must enter the market fast since speed is the main concern and not quality. d. This new product will help the company attain... 1. Kelly Thomas is of the view that Pat Lambert should not be assigned leadership since she doubts Pat's ability to lead. Kelly assumes that Pat doesn't possess the qualities required to lead "Operation Optimize" since Pat has irrelevant previous experience in a cereal industry. 2. Since Pat was unable to comprehend the term "QC," Kelly assumes Pat has no knowledge of quality control and the difficulties associated with the same. Thus she feels it would be impossible to produce a new product under her guidance. Cliff O'Connor: Cliff believes that a new product would "recapture our position as a market leader with our technology." Cliff further argues that AcuScan needs Pat's creativity. He views "Operation Optimize" as not something too different from the old product iScanner. Pat Lambert: Argues that iScanner should be modified and should be launched in a non-vertical market and sees this as the only viable solution for long-term growth. Pat argues that Kelly initially said it was easier to build on the existing product and create a new product from an old one. Finally, Pat also needs additional funding to hire an outside contractor for the completion of this product on time. After analyzing the situation

Nursing - Assignment Example ntage of SOAP is that there is documentation which ensures communication among different health professionals that may be involved in treatment of that patient. This will prevent any misdiagnosis which may be blamed on one health worker only and which may lead to that health worker being sued. In case of anything going wrong for the patient, all the health workers who were involved and integrated by the SOAP will be in trouble but that is rarely the case. The other legal advantage of a SOAP documentation system is that since the documentation is in note form, the progress notes and all other information appear on one page and hence no chances of ignoring part of the notes or not seeing all the notes as a result of missing pages as is common with other traditional documentation systems (Iyer, et al. 2006). This will ensure that non maleficence and beneficence are promoted as no information which may cause harm to the patient will be left without being addressed. This documentation system however has disadvantages too. One of the disadvantages is that every diagnosis is recorded in a different SOAP and this result to redundancy of the work. This may lead to some health workers failing to record all the information which legally amounts to neglect which may cause harm and also ignore the non maleficence code hence charges can be pressed for such a health worker. This is the commonly used documentation system where the patient’s care and treatment information is recorded chronologically over the duration the patient is in hospital or in a health facility (Iyer, et al. 2006). One of its main legal advantages is that it is useful in emergency situations to quickly collect information of patient’s health and treatment interventions necessary. In case anything fails to be recorded or is misreported at that time, the health worker has legal protection as it was an emergency which is allowed by law. Traditional narrative is the system that most health workers are

Shifting Genres - Essay Example Peter answered the man by telling him they were going to Fargo in U.S.A. shockingly the man told them that they must be joking because they can not survive in that place since it is too cold. The man laughed, but Peter Dut did not know the reason beyond the laughter. Having lived at Kakuma refugee camp the boys had not experienced cold climate since Kakuma is 1000C. By that time, the temperature in Fargo had dropped below 150C. The boys had only experienced cold from a frozen bottle of water given to them by aid worker in the refuge camp. Peter and his brothers belong to a number of 10,000 boys in Kakuma refugee camp from Sudan, who went to seek refuge in 1992 during the civil war in the southern part. The lost boys were given names after Peter Pan’s orphan’s posse. A report from America showed that over 17,000 boys left Sudan and separated from their families in 1987 during the war. They fled to Ethiopia and then back to Sudan then finally to Kenya. They arrived in Kenya parentless, homeless and throng having walked over 1,000 miles. The boys were between the age 8 and 18 from the Dinka tribe. Many of the boys did not know their age and the aid workers gave them ages depending on their sizes. On the way to the camp, the number of boys reduced by half. Most of the boys died on the way because they were attacked by bandits, lions, swept away by river water and others attacked by crocodile. After living in a camp for 9 years without being governed the three brothers’ decided to move to America. The boys in the refugee camps were sponsored by the UN to study in America while others were to be released to start their own live because after five years they were 21 years. The time when the three brothers were to land in Fargo, snow was flowing in the streets and roads. Later, Peter with his brothers, Riak, 15 and Maduk 17, arrived at their home apartment which was fully furnished by the

Motivation Through Acknowledgement Essay Example for Free

Motivation Through Acknowledgement Essay Impact of being a charismatic leader Leadership is about the ability to influence people by personal attributes and behaviours; different leadership qualities may be needed in different circumstances. Charismatic leadership: A charismatic leader is a leader whose followers are attracted to his or her personality and charm. People using this leadership style excel at working a room and making others feel that they are truly important and needed for the leader (and the cause) to be successful. These magnetic leaders do this through actions such as: Direct eye contact Remembering personal details about the person they are speaking with e. g. use of name or enquiry after family/social matters Giving their complete focus to the other person for the time they are with them Reading their surroundings and being skilled at detecting the moods of the audience and Adjusting his or her behaviours and speech to suit the situation at hand. Their approach when leading teams is to have their enthusiasm rubs off on their team members by being extremely positive and energetic. Teams do, however, need more than just a charming leader to keep them sustainable over the long term. Impacts of Charismatic Leadership Selling The Vision: These leaders are often exceptional at selling the vision and getting people to come along for the ride. They are geniuses at helping people to see possibilities and potentials to buy into something bigger than themselves. They are generally masters at weaving stories and anecdotes that enable people to buy into a big dream e.g. JFK leading a nation to put the first man on the moon Inspiring: Their generally optimistic and positive nature draws people to them like a moth to a flame. Often these leaders do inspire people to be at their best and the work environments they create can be very motivating to employees and colleagues alike. Drive Results. A highly charismatic leader can have people willing to walk over hot coals for him or her. Because of this they can achieve results and often get things done that other leadership styles may not. Think Hitler, Lee Iacocca Charismatic leadership is certainly a dynamic and empowering form of leadership, and combined with other styles of leadership, it creates a powerful force that gives people the enthusiasm and  self-management to achieve great results. A leader is a person who has a vision, a drive and a commitment to achieve that vision, and the skills to make it happen. A leader is a person who influences a group of people towards the achievement of a goal.

Basic Structure Of A Computer System Computer Science Essay

Basic Structure Of A Computer System Computer Science Essay A computer is an electronic device capable of manipulating number and symbols, first taking input, processing it, storing and giving out output under a control of set instructions which is known as a program. A general purpose computer requires the following hardware components: memory, storage device (hard disk drive), input device (keyboard, mouse etc.), output device (screen, printer etc.) and central processing unit (CPU). Many other components are involved in addition to the listed components to work together efficiently. Computers can be classified by size and power as follows: Personal computer: Personal computers are small computers based on a microprocessor. A personal computer has a keyboard for inputting data, a monitor for output and a storage device for saving data. Workstation: workstations are usually powerful than a personal computer. It has more powerful microprocessor and a higher-quality monitor. Minicomputer: Mini computers are multi-user computer capable of supporting from 10 to hundreds of users simultaneously. Mainframe computer: Mainframe computers are powerful multi-user computer capable of supporting many hundreds or thousands of users simultaneously. Super computer: Super computers are extremely fast computers that can perform hundreds of millions of instructions per second. MAIN REPORT COMPUTER SYSTEM A computer system can be represented using the following block diagram: CPU Bus Interface Timing and Control Address Bus ALU I/O RAM ROM Keyboard Mouse etc. Data Bus Control Bus Clock The CPU is can be expanded into three main parts: The ALU (Arithmetic and Logic Unit), The Bus interface Unit, and The Control Bus. The clock is an electronic circuit that gives regular pulses to the CPU. Faster clock speeds means more pulses to the CPU and the instructions are stepped through faster. The memory chip contains millions of separate memory stores and each of these locations has a unique number. This is known as memory address. The CPU stores data at any of these addresses and fetch the content back when required. RAM stands for Random Access Memory. These chips store the instructions for running the operating system and any computer application. This memory also stores all the data that is being worked on. RAM is a volatile memory which means that it only stores data while the computer remains switched on. When switched off, it loses all the stored data. ROM (Read Only Memory) on the other hand is a chip with program instructions permanently burned into it. The content is not lost even if the machine is switched off. The CPU can either fetch data from or write data when the appropriate memory location is accessed. Such data is transferred from the CPU to the memory location along the Data Bus. The control Bus is a set of tracks on the computers motherboard that run from the CPU to the devices and works under the direction of the CPU. LOGIC GATES Logic gates perform logical operation on one or more logic inputs and produce a single logic output. It processes signals which represent true or false. It is called Boolean logic and is most commonly used in digital circuits. Logic gates are identified by their function: NOT, AND, NAND, OR, NOR, EX-OR and EX-NOR and they are usually represented by capital letters. Logic Gate Symbols There are two series of symbols for logic gates: the traditional symbols which have distinctive shapes making them easy to recognise so they are widely used, and the International Electro technical Commission (IEC) symbols which are rectangles with a symbol inside to show the gate function. Traditional Symbols Source: http://www.kpsec.freeuk.com/gates.htm IEC Source: http://www.kpsec.freeuk.com/gates.htm Inputs and Outputs All Gates except a NOT gate have two or more inputs. A NOT gate has only one input and all gates have only one output. In the following figure, A and B are inputs and Q is the output. Source: http://www.kpsec.freeuk.com/gates.htm Other types of gate used are NOT gate, AND gate, NAND (NOT AND) gate, OR gate and NOR (NOT OR) gate. Truth tables A truth table is a good way to show the function of a logic gate. It shows the output states for every possible combination of input states. The symbols 0 (false) and 1 (true) are usually used in truth tables. The example truth table on the right shows the inputs and output of an AND gate. Input A Input B Output Q 0 0 0 0 1 0 1 0 0 1 1 1 Computer numbering system Humans speak to one another in a particular language and we use different words and letters. Although we type words and letters in the computer, the computer translates those words and letters into numbers. Computers talk and understand in numbers. Those number systems are: Decimal, Hexadecimal, and Binary. The Decimal Number System is the system is most frequently used in arithmetic and in everyday life. The decimal number system is also known as the base 10 number system as the position in the number represents an incremental number with a base of 10. Each position only contains a number between 0 and 9. The Hexadecimal number system is used to represent memory addresses or colours. It is also known as the base 16 number system, because each position in the number represents an incremental number with a base of 16. Since the number system is represented in 16s, there are only 10 numbers and 5 letters (A to F). The Binary number system is used by most machines and electrical devices to communicate. It is also known as the base 2 number system, because each position in the number represents an incremental number with a base of 2. Since it is represented it 2s, there are only 2 numbers that can be a value in each position 0 or 1. CPU COMPONENTS The CPU is the intelligence of the machine but it needs a pre-written program to create, use and modify the data. If the computer needs to compare two numbers, or add two numbers, this is carried out inside the CPU and the numbers have to be fetched into the CPU from the computers memory chip. The three main components of CPU are: Arithmetic logic Unit (ALU), Bus Interface unit, and the Control Bus. Arithmetic Logic Unit (ALU) carries out all the calculations and decision making tasks. The ALU uses devices called gates that receive one or more inputs and based up what function they are designed to perform, outputs a result. The basic operations of an ALU include adding and subtracting binary values as well as performing logical operations such as AND, NOT, OR AND XOR. The Bus Interface Unit takes the data to and from the CPU which is held inside internal registers (small memory stores) along the external Data Bus to read and write memory and devices. The Data Bus carries information in both directions. The Bus Interface Unit also places the required location addresses on the Address Bus, so that the required devices can be accessed for reading or writing. The Control Bus is the physical connection that carries control information between the CPU and other devices within the computer. It decodes all program instructions and dictates all the CPUs control and timing mechanisms. It sends out the read and write signals on the Control Bus. COMPUTER MEMORY The computer has to temporarily store the program and data in an area where it can be used by the computers processor to work. This area is known as the computers memory. It consists of computer chips that are capable of storing information. These information could be: the operating system (e.g. DOS, windows etc.), the instruction of the program to run (e.g. a database or a drawing program), or the data that is used or created (e.g. letters from word-processing or records from a database). There are different types of memory used in a computer system. They are: Cache memory, Random Access Memory (RAM), Read Only Memory (ROM), and Virtual Memory. Cache memory is extremely fast memory that is built into a computers CPU (L1 cache) or in some cases located next to it on a separate chip (L2 cache). L1 cache is faster than L2 cache as it is built into the CPU. These days, newer computer come with L3 cache which is faster than RAM but slower than L1 and l2 cache. Cache memory is used to store instructions that are repeatedly required to run programs and helps to improve overall system speed. The reason it is so fast is that the CPU does not have to use the motherboards system bus for data transfer. Random Access Memory (RAM) is the memory chip that consists of a large number of cells, each cell having a fixed capacity for storing data and unique address. RAM is a volatile memory which means all the programs and data in the memory is lost when the machined is switched off. There are different types of RAM modules available such as SODIMM, SDRAM, DDR, DDR2 and DDR3. SODIMM are used for laptops whereas the rest are used for desktop computers. Read Only Memory (ROM) is a memory chip in which the program instructions are permanently burned into. It is non-volatile which means its content is not lost even when the machined is switched off. It is used to store some of the system programs that keep the computer running smoothly. For example computer BIOS (basic input out system) is stored on the ROM. There are different types of ROM available such as Programmable ROM (PROM), Erasable Programmable ROM (EPROM), and Electrically Erasable Programmable ROM (EEPROM). Virtual Memory is a part of most operating system. It is used when the amount of RAM is not enough to run all the programs. If the operating system, an email program, a web browser, a word processor, a Photoshop application are loaded into the RAM simultaneously, the RAM will not be able to handle all applications and thus the computer looks at RAM for areas that have not been used recently and copies them onto the hard drive. This frees up space in RAM to load new application. But because the read/write speed of a hard drive is much slower than that of RAM, the performance is not satisfactory. It is not recommended to use virtual memory as it is slow. The solution to this problem would be to upgrade the memory. SYSTEM SOFTWARE A computer system is not complete without system software. For a computer to perform any tasks, both software and hardware are equally important. System software gives life to hardware. System softwares are the files and programs that make up a computers operating system. It includes libraries of functions, system services, driver for hardwares, system preferences, and other configuration files. System software comprises of Assembler, Debugger, Compilers, Operating System, File management tools etc. The system software is installed on the computer when the operating system is installed. It can also be updated by running programs such as windows update. The system software is also called low-level software as it runs at the most basic level of the computer. It generates the user interface and allows the operating system to interact with the hardware; however system software is not meant to be run by the end user like application programs. Application programs such as web browser, or Microsoft word is often used by the end user whereas the end user does not use an assembler program unless he/she is a computer programmer. The system software runs in the background and thus the user does not have to worry about what the system software is doing. CONCLUSION In the report, the basic structure of a computer system was described with diagram. Different components such as CPU, memory, BUS, input/output devices that form a computer system were identified and explained. General ideas about Logic gates were given and different number systems used by computers to represent data were also described. As the CPU is the main part of a computer system, it was further looked into and Arithmetic Logic Unit, Control Bus and Bus interface Unit were discussed. Different types of memory and their uses were explained and the importance of the system software was discussed finally.

A Turning Point Essay -- Personal Narrative Essay

A Turning Point A melting pot of Asian and European culture, a land of scientific growth and opportunity, and a place grown rich with custom and tradition, Singapore is a country unlike any other. Traveling to Singapore for the Second APEC Youth Science Festival, I encountered an environment where people of different backgrounds come together, a fusion of ideas and insight, and a piece of artwork painted rich with the colors of each individual culture. Upon my return to the United States, I brought with me an enhanced cultural awareness, a greater understanding of the international scientific community, a wealth of knowledge, as well as numerous life-long friendships. The cultural benefits of the APEC Youth Science Festival are innumerable. Having virtually no previous understanding of Asian customs and traditions, I found the various cultural performances educational and truly amazing. A breathtaking musical presentation by Korean drummers and a colorful parade of traditional Indonesian costumes were two of the more memorable performances. Throughout the cultural presentations, I was in awe of the distinct differences that became increasingly apparent between each of the individual Asian cultures. My favorite part of the trip was my overnight stay with a Sri Lankan family. With my family I visited Little India, one of the liveliest districts in Singapore where traditional Indian culture is ... ... New Zealand, I have developed a vast network in just two weeks. Sharing ideas and insight, culture, and new experiences has brought us all together despite our differences. Together we did everything including riding "The Venturer" at the Singapore Science Center, researching Nepal Virus, and traveling on a Night Safari. I am amazed at how much I have learned in two weeks, and I know I will cherish this experience for a lifetime. In the future I hope only to enhance my cultural awareness, work to promote international scientific collaboration, express my appreciation for the vital work done by organizations such as APEC, and stay in close contact with the wonderful friends I made in two amazing weeks overseas.

The Choosing Essay by Liz Lochead

The Choosing Essay Marianne Lavery The poem â€Å"The Choosing† by Liz Lochead deals with problems of growing up and the issue of education through the two central characters, Mary and Liz. This poem is about two young girls called Mary and Liz who grew up together living an ordinary life. They were both intelligent and ambitious. They were best friends for years at primary school until they had the chance to go to secondary school and they went their separate ways to start their new lives. Later on in the poem they meet very unexpectedly on a bus years later. This really does show the reader just how much the two girls have change from primary school. In stanzas 1, 2 and 3 the poet Liz Lochead has emphasized the similarities between the two girls by describing their appearances. They both had the same â€Å"mouse-coloured† hair which suggests they are ordinary. Also they were polite, smart and proud. The poet has used repetition by saying how â€Å"equally proud† they are. This emphasizes the similar attitude the girls had towards their education. Alliteration has also been used. â€Å"Collins’ Children’s Classics†. Stanza 4, describes how their lives took different paths. Mary moved because of cheaper rent somewhere else and Liz stayed where she was, in her hometown where she grew up. Mary’s father had a very bad attitude towards girls’ education and he is also sexist. He didn’t believe in high school education especially for girls or in forking out for uniforms†. Marys family had also financial difficulties according to the poet. The final three stanzas shows that ten years have passed since the two girls went their separate ways but they find their selves sitting in the same bus as each other. However this time as they meet, Mary does not recognise Liz. Mary is sitting next to her husband â€Å"who is tall, curly haired a nd has eyes only for Mary†.
