Problem Set - Assignment Example The old formula works better. Two people who took the old formula felt relief in less than 20 minutes, compared to none who took the new formula. Also, the worst result – near 120 minutes - was the new formula. The average time for the new formula to relieve a headache is lower than the average time for the old formula. I would conclude that people taking the new formula will tend to feel relief about 20 minutes sooner than those taking the old formula. The number of patients in the two groups is not the same so there is no fair way to compare the two formulas. A baseball fan likes to keep track of statistics for the local high school baseball team. One of the statistics she recorded is the proportion of hits obtained by each player based on the number of times at bat as shown in the table below. Which of the following graphs gives the best display of the distribution of the proportion of hits in that it allows the baseball fan to describe the shape, center, and spread of the variable, proportion of hits? Reasons: For item No. 6: The percentage of scores having 30 or below is about half of the lower 25% as the box both for section 1 and 2 as shown in their respective boxplot. For item No. 7 The same as in No. 6. Since 80 is the median score the upper 50% are having scores 80 and above for both sections. For item No. 8 The best presentation is plotting the percentage of hits to the number of players who made it. Graph C best represents the trend. It tells how many students make the highest percentage hits, and so on and so forth.

Harvard Guide to Happiness, Freakonomics, Cant a Woman Be Einstein Essay Example for Free

Harvard Guide to Happiness, Freakonomics, Cant a Woman Be Einstein Essay The methods suggested from a research conducted over 10 years on 1,600 Harvard students are relevant today more than ever. The global trend of shift in workforce from manufacturing to white collar work necessitates workers obtain higher degrees of education. Individuals with higher education degree are more equipped with the capacity to better manage given tasks of the service sector employing analytical thinking. Workforce comprised of such highly educated individuals enhances competitiveness in the increasingly complex global economy. Thus the value of individual academic pursuit is critical in sustaining economic development of a nation. Assuming that students furthering their studies decide based on freewill, keeping students motivated is the key to encouraging them to pursue higher education. Basing on the results from the study, increasing interaction among the various elements within the school system such as faculty and peer-students propel students to achieve higher grades, become more intellectually engaged and increase their overall happiness. An NBER study of a group of Kenyan girls in 69 primary schools comparing those who were randomly selected to receive scholarships to those who did not receive any surprisingly concluded that greater education does not in fact lead to greater democracy. However I believe the relationship between education and democracy can either be strengthened or weakened based on the content of the education received by the citizens and how it is famed in the classroom setting. Education systems that emphasize and value freedom of expression through heated discussion among peers inevitably provide an opportunity for the students to experience democratic way of handling things. The way information was given to the young girls in Kenya and its substance may have been the reason in the failure of increased education to result in greater democracy. The essay that demonstrated that biological difference exists between male and female but does not suggest a difference in aptitude pose an important issue in the field of education. I agree that the results hint a change in the education system but I hesitate to agree with Leonard Sax in his belief that â€Å"coed schools do more harm than good†. The fact that current coed schools might not provide an environment for boys and girls to learn at the pace of their maturing brains does not necessitate those students to be educated in single-sex schools. The problem, if there is any, would lie in the lack of division of classes based on the level of each subject. Division of class in coed schools based on proficiency, for instance beginners, intermediate and advanced seems an appropriate response that effectively deals with the problem embraces outliers at the same time.

Plath’s Stings †An Analysis :: Stings Essays

Plath’s Stings – An Analysis  Ã‚   â€Å"Stings† is a feminist poem by Sylvia Plath. The last two stanzas are important in understanding Plath’s feeling while writing the poem. In lines fifty-one through sixty the speaker conveys that, although she may have been a drudge before, she will not be one any more. She refuses to submit to society and be a hard working drudge. The speaker believes she is more than that — perhaps even a queen: â€Å"They thought death was worth it, but I have a self to recover, a queen.† The speaker in the poem realizes that she has the potential to be a queen, and she didn't want to give up on that dream. She wanted to get away from her drudge-like surroundings that had once killed her spirit. She would ‘rise above the fray’ and get away from â€Å"the engine that killed her- the mausoleum, the wax house.† The beehive had become more of a prison, and she wants to get away from it very badly. The last two stanzas are important because they are metaphoric for the way women are suppressed and forced to stay at home — doing the cleaning and watching the children. It was considered wrong and out of the norm if a woman wished to get a career for her own. Plath is trying to tell us that women who have become â€Å"drudges† as a result of marriage have more potential than just being house keepers and baby-makers. Other stylistic elements that Plath uses include imagery and symbolism. She is very vivid in describing the way the bee looks in the last two stanzas: †With her lion-red body, her wings of glass.....red scar in the sky, red comet.† The words create a clear picture in of what she must have looks like, escaping the â€Å"mausoleum,† a symbol of the beehive and, therefore, of the speaker's entrapment. It â€Å"killed her,† or rather, killed her spirit.

Analysis of Cloud Computing Architectures

Laptops, PDA, and Smoothness's). Computational power and battery life s one of the major issues of these mobile devices. To overcome these problems clones of mobile devices are created on cloud servers. In this paper, we define clone cloud architecture and brutalized screen architecture in cloud computing. Clone Cloud is for the seamless use of ambient computation to augment mobile device applications, making them fast and energy efficient and in a Brutalized Screen; screen rendering is done in the cloud and delivered as images to the client for interactive display.This enables thin-client mobile devices to enjoy many computationally intensive and graphically rich services. Keywords: Cloud Computing, Service Models, Clone Cloud, Brutalized Screen l. Introduction Cloud Computing has been one of the most booming technology among the professional of Information Technology and also the Business due to its Elasticity in the space occupation and also the better support for the software and the Infrastructure it attracts more technology specialist towards it.Cloud plays the vital role in the Smart Economy, and the possible regulatory changes required in implementing better Applications by using the potential of Cloud The main advantage of the cloud is that it gives the low cost implementation for infrastructure and some higher business units like Google, MM, and Microsoft offer the cloud for Free of cost for the Education system, so it can be used in right way which will provide high quality education [3]. A.Cloud Computing Service Models Cloud computing can be classified by the model of service it offers into one of three different groups. These will be described using the AAAS taxonomy, first used by Scott Maxwell in 2006, where â€Å"X† is Software, Platform, or Infrastructure, and the final â€Å"S† is for Service. It is important to note, as shown in Figure, that AAAS is built on Pass, and the latter on alas. Hence, this is not an excluding approach to classification, but rather it concerns the level of the service provided.Each of these service models is described in the following subsection. [pick] Fig. 1 Cloud computing Architecture 1) alas (Infrastructure as a Service): The capability provided to the customer of alas is raw storage space, computing, or network resources with which the customer can run and execute an operating system, applications, or any software that they choose. The most basic cloud service is alas [7]. In this service, cloud providers offer computers as physical or as virtual machines and other resources. Pass (Platform as a Service): In the case of Pass, the cloud provider not only provides the hardware, but they also provide a toolkit and a number of supported programming languages to build higher level services. The users of Pass are typically software developers who host their applications on the platform and provide these applications to the end-users. In this service, cloud providers deliver a com puting platform including operating system, programming languages execution environment, database and web servers. ) AAAS (Software as a Service): The AAAS customer is an end-user of complete applications running on a cloud infrastructure and offered on a platform on-demand. The applications are typically accessible through a thin client interface, such as a web browser. In this service, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. This service is based on the concept of renting software from a service provider rather than buying it.It is currently the most popular type of cloud computing because of its high flexibility, great services, enhanced capability and less maintenance. B. Deployment Models Clouds can also be classified based upon the underlying infrastructure deployment del as Public, Private, Community, or Hybrid clouds. The different infrastructure deployment models are distinguishing by thei r architecture, the location of the data center where the cloud is realized, and the needs of the cloud provider's customers [4]. Several technologies are related to cloud computing, and the cloud has emerged as a convergence of several computing trends. ) Types of Cloud Computing Environments: The cloud computing environment can consist of multiple types of clouds based on their deployment and usage [6]. Public Clouds This environment can be used by the general public. This includes individuals, corporations and other types of organizations. Typically, public clouds are administrated by third parties or vendors over the Internet, and services are offered on pay-per-use basis. These are also called provider clouds. Private Clouds A pure private cloud is built for the exclusive use of one customer, who owns and fully controls this cloud.Additionally, there are variations of this in terms of ownership, operation, etc. The fact that the cloud is used by a specific customer is the disti nguishing feature of any private cloud. This cloud computing environment sides within the boundaries of an organization and is used exclusively for the organization's benefits. These are also called internal clouds. Community Clouds When several customers have similar requirements, they can share an infrastructure and might share the configuration and management of the cloud.Hybrid Clouds Finally, any composition of clouds, be they private or public, could form a hybrid cloud and be managed a single entity, provided that there is sufficient commonality between the standards used by the constituent clouds. II. AUGMENTED EXECUTION OF SMART PHONES USING CLONE CLOUDS B Chunk,[10] introduce the concept of clone cloud. The idea of introducing this concept is to improving the performance of hardware limited smart phones by using their proposed clone cloud architecture.The core method is using virtual machine migration technology to offload execution blocks of applications from mobile devic es to Clone Cloud. Clone Cloud boosts unmodified mobile applications by off-loading the right portion of their execution onto device clones operating in a computational cloud. Conceptually, our system automatically transforms a single-machine execution (e. G. , computation on a smart phone) into a distributed execution optimized for the outwork connection to the cloud, the processing capabilities of the device and cloud, and the application's computing patterns.The underlying motivation for Clone Cloud lies in the following intuition: as long as execution on the clone cloud is significantly faster than execution on the mobile device (or more reliable, more secure, etc. ), paying the cost for sending the relevant data and code from the device to the cloud and back may be worth it [9]. Ill. CLONE CLOUD ARCHITECTURE The design goal for Clone Cloud is to allow such fine-grained flexibility on what to run where. Another design goal is to take the programmer out of the business of applica tion partitioning [10].In a Clone Cloud system, the ‘Clone' is a mirror image of a Semaphore running on a virtual machine. By contrast with smart phones, such a ‘clone' has more hardware, software, network, energy resources in a virtual machine which provides more suitable environment to process complicated tasks. In the diagram, a task in smart phone is divided into 5 different execution blocks (we mark them as different colors), and the smart phone is cloned (brutalized) as an image in distributed computing environment. Then the image passes some computing or energy-intensive blocks (the Green blocks) to cloud for processing.Once those execution blocks have been completed, the output will be passed from Clone Cloud to the Semaphore [11]. [pick] Fig. 2 Clone Cloud Architecture A major advantage of the Clone Cloud is enhanced smart phones performance. Bung takes a test by implementing a face tracking application in a smart phone with and without Clone Cloud. The result s hows that only 1 second is spent in Clone Cloud environment but almost 100 seconds in the smart phone without Clone Cloud. Another advantage of Clone Cloud is reduced battery consumption as smart phones o not use its CPU as frequently.The disadvantages of Clone Cloud are handover delay, bandwidth limitation. As we know that the speed of data transmission between smart phones and base station is not consistent (according to the situation), therefore, the Clone Cloud will be unavailable if mobile users walk in the signal's blind zone. A. Evaluation of Applications To evaluate the Clone Cloud Prototype, Bung-Goon Chunk [10] implemented three applications. We ran those applications either on a phone?a status quo, monolithic execution?or by optimally partitioning for two settings: one with Wi-If connectivity and one with 36.We implemented a virus scanner, image search, and privacy- preserving targeted advertising. The virus scanner scans the contents of the phone file system against a li brary of 1000 virus signatures, one file at a time. We vary the size of the file system between KBPS and 10 MBA. The image search application finds all faces in images stored on the phone, using a face-detection library that returns the mid-point between the eyes, the distance in between, and the pose of detected faces.We only use images smaller than KBPS, due to memory limitations of the Android face-detection library. We vary the number of images from 1 to 100. The privacy-preserving targeted- advertising application uses behavioral tracking across websites to infer the user's preferences, and selects ads according to a resulting model; by doing this tracking at the user's device, privacy can be protected. 1) Time Save Fig. 3 Mean execution times of virus scanning (VS.), image search (IS), and behavior profiling (BP) applications with standard deviation error bars, three input sizes for each.For each application and input size, the data shown include execution time at the phone al one, that of Clone Cloud with Wi-If (C-Wi-If), and that of Clone Cloud tit 36 (C-G). The partition choice is annotated with M for â€Å"monolithic† and O for â€Å"off-loaded,† also indicating the relative improvement from the phone alone execution 2) Energy Save Fig. 4 Mean phone energy consumption of virus scanning (VS.), image search (IS), and behavior profiling (BP) applications with standard deviation error bars, three input sizes for each.For each application and input size, the data shown include execution time at the phone alone, that of Clone Cloud with Wi-If (C-Wi-If), and that of Clone Cloud with 36 (C-G). The partition choice is annotated with M for â€Å"monolithic† and O for â€Å"off-loaded,† also indicating relative improvement over phone only execution. Fig. 3 and 4 shows execution times and phone energy consumption for the three applications, respectively. All measurements are the average of five runs. Each graph shows Phone, Clone Cloud with Wi-If (C-Wi-If), and Clone Cloud with 36 (C-G).C- Wi-If and C-G results are annotated with the relative improvement and the partitioning choice, whether the optimal partition was to run monolithically on the phone (M) or to off-load to the cloud (O). In the experiments, Wi-If had latency of moms and bandwidth of 6. Mbps, and 36 had latency of mass, and bandwidth of 0. Mbps. Clone Cloud chooses to keep local the smallest workloads from each application, deciding to off-load 6 out of 9 experiments with Wi-If. With 36, out of all 9 experiments, Clone Cloud chose to off-load 5 experiments.For off-loaded cases, each application chooses to offload the function that performs core computation from its worker thread: scanning files for virus signature matching for VS., performing image processing for IS, and computing similarities for BP. C Wi-If exhibits significant speed-ups and energy savings: xx, xx, and lox speed-up, and xx, xx, and xx less energy for the largest workload of each of the three applications, with a completely automatic modification of the application binary without programmer input.A clear trend is that larger workloads benefit from off-loading more: this is due to amortization of the migration cost over a larger computation at the clone that receives a significant speedup. A secondary trend is that energy consumption mostly follows execution time: unless the phone switches to a deep sleep state while the application is off-loaded at the clone, its energy expenditure is proportional to how long it is waiting for a response. When the user runs a single application at a time, deeper sleep of the phone may further increase observed energy savings.We note that one exception is C-G, where although execution time decreases, energy consumption increases slightly for behavior profiling with depth 4. We believe this is due to our coarse energy cost model, and only occurs for close decisions. C-G also exhibits xx, xx, and xx speed-up, and xx, xx, and xx less energy for the largest workload of each of the three applications. Lower gains can be explained given the overhead differences between Wi-If and 36 networks. As a result, whereas gyration costs about 15-25 seconds with Wi-If, it shoots up to 40-50 seconds with 36, due to the greater latency and lower bandwidth.In both cases, migration costs include a network-unspecific thread-merge cost? patching up references in the running address space from the migrated thread?and the network-specific transmission of the thread state. The former dominates the latter for Wife, but is dominated by the latter for 36. Our current implementation uses the DEFLATE compression algorithm to reduce the amount of data to send; we expect off-loading benefits to improve with other optimizations targeting the network overheads (in reticular, 36 network overheads) such as redundant transmission elimination.B. Problem in Clone Cloud The disadvantages of Clone Cloud are [1 1] handover delay, bandwidth limit ation. As we know that the speed of data transmission between Semaphore and base station is not consistent (according to the situation), therefore, the Clone Cloud will be unavailable if mobile users walk in the signal's blind zone. Offloading all applications from Semaphore to the cloud cannot be Justified for power consumption, especially for some lightweight applications which are suitable to be deployed in local smart phones. V.BRUTALIZED SCREEN Screen rendering [1 3] can also be moved to the cloud and the rendered screen can be delivered as part of the cloud services. In general, the screen represents the whole or part of the display images. In a broad sense, it also represents a collection of data involved in user interfaces such as display images, audio data, mouse, keyboard, pen and touch inputs, and other multiplicity inputs and outputs. Screen fertilization and screen rendering in the cloud doesn't always mean putting the entire screen-rendering task in the cloud.Depending on the actual situations?such s local processing power, bandwidth and delay of the network, data dependency and data traffic, and display resolution?screen rendering can be partially done in the cloud and partially done at the clients. A. Screen Fertilization Fig. 5 The Conceptual diagram of the cloud client computing architecture. Rendering a screen in the cloud also introduces obstacles for the client devices to access the virtual screen, if it needs to maintain high-fidelity display images and responsive user interactions.Fortunately, we have already developed a number of advanced multimedia and networking technologies to address these issues. Ultimately, we would like to define a common cloud API for cloud computing with scalable screen fertilization, with which the developers never have to care where the data storage, program execution, and screen rendering actually occur because the cloud services for the API will adaptively and optimally distribute the storage, execution, an d rending among the cloud and the clients. B.Remote Computing With Brutalized Screen The cloud-computing conceptual architecture depicted in Fig 5, we have developed a thin-client, remote-computing system that leverages interactive screen-removing cosmologies. Thin-client, remote-computing systems are expected to provide high- fidelity displays and responsive interactions to end users as if they were using local machines. However, the complicated graphical interfaces and multimedia applications usually present technical challenges to thin-client developers for achieving efficient transmissions with relatively low bandwidth links.Figure depicts the proposed thin-client, remote-computing Fig. 6 The interactive screen removing system System, which decouples the application logic (remote) and the user interface local) for clients to use remote servers deployed as virtual machines in the cloud. The servers and the clients communicate with each other over a network through an interactive screen-removing mechanism. The clients send user inputs to the remote servers, and the servers return screen updates to the clients as a response.

No Fear Shakespeare Essay

In English class, everyone lets out loud groans when they hear about their next units: Shakespeare. With the class complaining about the hard language and the difficulty of understanding the plays, the teacher might grow exasperated and let them read the infamously talked about book No Fear Shakespeare. The teachers are doing question thing when they keep a supplementary text with the original. Yes, 15th century Elizabethan era is a tad difficult to understand, but that is one of the beauties of Shakespeare. No Fear has a good translation but is missing a few key elements such as symbolism, poetry, allusions, and other literary techniques. I think the original version is much better than the translated version because it has more appeal. No Fear Shakespeare is a series of translations of the Bard’s famous works to the modern-day language that is used today to make it easier to understand. I must admit that the translation is well written and is a much easier read than the original. No fear should be used for non-English speakers to read along but still have the original. Shakespeare’s language is broken down in the translation and takes away the finesse the original has. In the first soliloquy of infamously â€Å"emo-tastic† Hamlet, his first line in the speech is â€Å"Oh, what a rogue and peasant slave am I! † in the original as opposed to the translated one that says â€Å"Now I’m alone. Oh what a mean low-life I am! † Now compare them and see which sounds more poetic and more passionate. Shakespeare has a way of making such a self-loathing speech sound so passionately powerful and beautiful. The translated version is too literal while Shakespeare was all about the symbolisms and metaphors that was his trademark. In this famous â€Å"to be or not to be† speech is another example. â€Å"To be or not to be? That is the question. † Is destroyed with â€Å"the question is: is it better to be alive or dead? † The point of that line is to be used for a variety of situations it has been taken too seriously. It’s more poetic and a bit dramatic (in a good way) to say â€Å"to be or not to be† rather than â€Å"should I kill myself to end all the hardships or just live with it miserably? † It’s almost as if Shakespeare’s version is a pretty girl who wears a lot of make-up and looks attractive until you see her without the make-up and see what she actually looks like unmasked so to speak when it is taken into No Fear Shakespeare. The last line of this speech is worse saying â€Å"But shh, here comes the beautiful Ophelia. Pretty lady; please remember me when you pray. Instead the original â€Å"The fair Ophelia-Nymph, in thy orisons be all my sins remembered. † The allusion to Greek mythology is one of the things that make Shakespeare’s work significant because his world was controlled by the monotheistic Roman Church. He uses a polytheistic religion for his allusions but No fear gets rid of some of it to make it more comprehensible. The No Fear Shakespeare series should not be taught in regular English speaking class because it takes away the symbolism, rhyme, and beauty of the literature. It should be used as a reference outside of school. As one of my friend said â€Å"the teacher is supposed to teach you what it means and if you don’t get that then you can use the book translation. † I agree with this completely. They’re supposed to be teaching Shakespeare to enlighten the students in ways that connects to them. If they have a bad teacher that is when the translator is depended on to teach what Shakespeare is writing. If the language was better understood by students you’d be able to realize that the themes and plots are so relatable. What teenager doesn’t relate to Hamlet with his depression or with his feeling of being misunderstood? As Alexandra Petri’s article â€Å"On the Bard’s Birthday: Is Shakespeare Still Relevant? † it states â€Å"If we want to do a modern staging of his work, we’ll have to stipulate that ‘In fair Verona, where we lay our scene/the cell reception was spotty/from ancient grudge that brake AT&T. † Sure we can’t exactly relate because most teens have cell phones to communicate, but it gives us a feel of if this was to happen in the â€Å"electronically deprived† centuries. It gives a link from the 21st century to the 15th century. The translation’s text book definition of Shakespeare does not give you that link, it just tells a story; it doesn’t have meaning behind it. Shakespeare has great insults as well, so why insult in modern language when you can confuse a fellow peer with beautiful Elizabethan. We shouldn’t fear Shakespeare we should learn to love him. He brings beauty and richness into literature that no other could do, especially in this age. He is thought to be a genius of the theatre. He has this originality that has influenced a lot of famous authors of modern-day literature so I say â€Å"Long live Shakespeare! †

What Is the Jet Stream and How It Affects Our Weather

What Is the Jet Stream and How It Affects Our Weather Youve probably heard the words jet stream many times while watching weather forecasts on TV. Thats because the jet stream and its location is key to forecasting where weather systems will travel. Without it, there would be nothing to help steer our daily weather from location to location. Rivers of Rapidly Moving Air Named for their similarity to fast moving jets of water, jet streams are bands of strong winds in the upper levels of the atmosphere. Jet streams form at the boundaries of contrasting air masses. When warm and cold air meet, the difference in their air pressures as a result of their temperature differences (recall that warm air is less dense, and cold air, more dense) causes air to flow from higher pressure (the warm air mass) to lower pressure (the cold air mass), thereby creating high winds. Because the differences in temperature, and therefore, pressure, are very large, so too is the strength of the resulting winds. Jet Stream Location, Speed,Direction Jet streams live at the tropopause (about 6 to 9 miles off  the ground) and are several thousand miles long. Jet stream winds range in speed from 120 to 250 mph, but can reach more than 275 mph. Oftentimes, the jet houses pockets of winds that move faster than the surrounding jet stream winds. These jet streaks play an important role in precipitation and storm formation. (If a jet streak is visually divided into fourths, like a pie, its left front and right rear quadrants are the most favorable for precipitation and storm development. If a weak  low pressure area  passes through either of these locations, it will quickly strengthen into a dangerous storm.) Jet  winds blow from west to east, but also meander north to south in a wave-shaped pattern. These waves and large ripples (known as planetary, or Rossby waves) form U-shaped troughs of low pressure that allow cold air to spill southwards, and upside-down U-shaped ridges of high pressure that bring warm air northwards.  Ã‚   Discovered by Weather Balloons One of the first names associated with the jet stream is Wasaburo Oishi. A Japanese meteorologist, Oishi discovered the jet stream in the 1920s while using weather balloons to track upper level winds near Mount Fuji. However, his work went unnoticed outside of Japan. In 1933, knowledge of the jet stream increased when American aviator Wiley Post began exploring long-distance, high-altitude flight. Despite these discoveries, the term jet stream was not coined until 1939 by German meteorologist Heinrich Seilkopf. Meet the Polar and Subtropical Jets While we typically talk about the jet stream as if there was only one, there are actually two: a polar jet stream and a subtropical jet stream. The Northern Hemisphere and the Southern Hemisphere each have both a polar and a subtropical branch of the jet. The Polar Jet:  In North America, the polar jet is more commonly known as the jet or the mid-latitude jet (so-called because it occurs over the mid-latitudes).The Subtropical Jet:  The subtropical jet is named for its existence at 30 °N and 30 °S latitude- a climate zone known as the subtropics. It forms at the boundary temperature difference between air at mid-latitudes and warmer air near the equator. Unlike the polar jet, the subtropical jet is only present in the wintertime- the only time of year when temperature contrasts in the subtropics are strong enough to form jet winds. The subtropical jet is generally weaker than the polar jet. It is most pronounced over the western Pacific. Jet Position Changes With the Seasons Jet streams change position, location, and strength depending on the season. In the winter, areas in the Northern Hemisphere may get colder than normal periods as the jet stream dips lower bringing cold air in from the polar regions. Although the height of the jet stream is typically 20,000 feet or more, the influences on weather patterns can be substantial as well. High wind speeds can drive and direct storms creating devastating droughts and floods. A shift in the jet stream is a suspect in the causes of the Dust Bowl. In spring, the polar jet starts to journey north from its winter position along the lower third of the U.S., back to its permanent home at 50-60 °N latitude (over Canada). As the jet gradually lifts northward, highs and lows are steered along its path and across the regions where its currently positioned. Why does the jet stream move? Well, jet streams follow the Sun, Earths primary source of heat energy. Recall that in spring in the Northern Hemisphere, the Suns vertical rays go from striking the Tropic of Capricorn (23.5 ° south latitude) to striking more northerly latitudes (until it reaches the Tropic of Cancer, 23.5 ° north latitude, on the summer solstice). As these northerly latitudes warm, the jet stream, which occurs near boundaries of cold and warm air masses, must also shift northward to remain at the opposing edge of warm and cool air. Locating Jets on Weather Maps On surface maps: Many news and media that broadcast weather forecasts show the jet stream as a moving band of arrows across the U.S., but  the jet stream isnt a standard feature of surface analysis maps. Heres an easy way to eyeball the jet position: since it steers high and low pressure systems, simply note where these are located and draw a continuous curved line in-between them, taking care to arch your line over highs and underneath lows. On upper level maps: The jet stream lives at heights of 30,000 to 40,000 feet above Earths surface. At these altitudes, atmospheric pressure equals around 200 to 300 mb; this is why the 200 and 300 mb level upper air charts are typically used for jet stream forecasting. When looking at other upper level maps, the jet position can be guessed by noting where pressure or wind contours are spaced close together.

Succession Planning Essay Example

Succession Planning Essay Example Succession Planning Essay Succession Planning Essay The most significant organizational development issue for private and public sector organizations is how to identify, develop and retain talented leaders for the future. The key to any organizations success is the right people in place to lead tomorrow immersed in the organizations values so they can sustain the culture. Succession planning has also been identified as top factor for employee retention. The Succession Planning Process With KMx, you will be able to build the foundation for a customized succession planning process that will work specifically for the organization. KMx Performance Management enables you to put the groundwork into place today for developing the best talent at every level of the organization. By designing a performance management profile for every key Job in the organization you will be creating a succession planning roadmap for the future. Stage 1 Creation of Knowledge and Skill Profiles (KIS Tables) In KMx, KIS Tables are a listing of knowledge and skill behaviors associated with a particular subject area. KIS Tables are subdivided into types (normally knowledge and skill) and areas to further classify behaviors. KIS Table behaviors are sequenced in order of increasing complexity or logical progression. In addition to providing the primary content cataloging schema with KMx, KIS Table also provide the foundation for development of personnel labor classifications that are specific enough to support the succession planning process. Leveraging wizards provided by KMx, the organization will be able to quickly identify and document the key knowledge, skills and competencies to drive the performance management program and set the framework for a succession plan. Stage 2 Mapping organizational best practices and corporate values to create a succession planning program Mapping best practices to subject area behaviors (created during Stage 1) with organizational performance measures provides the measuring stick for performing an analysis of the gap between current personnel capabilities and the needs of the organization. In addition to this key element in the succession planning process, the indexes created during this phase are incredibly valuable for: Just-in- time performance support Curriculum maintenance Selection and certification of training materials The mapping process is central to the KMx architecture and is supported by expert system wizards to facilitate the effort. Stage 3 Create the plan and supporting documentation In KMx, personnel requirements are mapped to supporting content and to the behaviors, conditions and standards of the requirements. The indexes created by this mapping process provide the organization with the ability to perform continuous monitoring and development of the following key succession planning elements: Employee skills verification documentation Training continuum development and maintenance Individual career management and performance evaluations Organizational Leadership development and planning documentation Overall staff development and recruiting planning Stage 4 Execute the plan Succession planning requires executive sponsorship. KMx provides the technology, reports and structure to ensure a comprehensive plan.
