...BP Control Functions Incontestably control mechanisms have existed within most businesses and organizations for guiding job responsibilities of employees toward accomplishing the company goals. There are many control mechanisms in a company. A strong human resources department controls managers and prevents employee abuse. Employee performance reviews and incentives assist in the control of employees. Compliance departments control legal risk and monitor operations to ensure the company follows state and federal rules. Financial budgets and accounting audits control financial risk. Product pricing controls marketing efforts. All the different departments must work together to create a strong and profitable company. The team will identify various control mechanisms in connection with British Protroleum (BP), compare, and contrast, determine the effectiveness, examine positive and negative reactions concerning their use, and provide an explanation about how the four functions of management are affected by them. BP used several control functions in its deep sea exploration process; all implemented to prevent the type of disaster they experienced in April 2010. There were systematic failures at every turn, creating a perfect storm and a devastating deep sea oil spill. The spill itself has been recorded as the largest oil spill to date in American history by the National Oceanic and Atmospheric Administration (Zeller, 2010). According to the same article, the BP spill was...

...Heuristics Nerissa Jones Professor Mattos Lithonia Campus CIS 111 Intro to Relation Dbase Mgt System Feb 28, 2013 Strayer University Heuristics We are finally approaching the end of this proposal but before I conclude this research data I would like to tell you about heuristics and how it is used to access your database information. This report explains the implementation of an algorithm to optimize a QT with heuristic optimization rules. These rules were taken from [1] chapter 16 and [2] chapter 11. Heuristic optimization rules are based on properties of operations as mathematical operations in the relational algebra. Summaries of these properties can be found both in [1] and [2] also. These properties give the following heuristic rules for query optimization: 1. Perform SELECT operations as far down the tree as possible. This has the effect of reducing the number of tuples in later binary operations which are highly expensive. 2. Perform PROJECT operations as far down the tree as possible. This has the effect of reducing the number of attributes in each tuple and reduces the memory requirements, attempting to cut down on secondary storage usage. 3. Combine successive SELECT operations into one composite SELECT operation and successive PROJECT...

...provides framework for modeling systems in which there is change and a way to deduce the predictions of such models; Calculus provides a way for us to construct relatively simple quantitative models of change and to deduce their consequence. By studying this, you can learn how to control the system to do make it do what you want it to do. CHAPTER 1: FUNCTIONS AND LIMITS FUNCTIONS * A bunch of ordered pairs of things with property that the first members of the pairs are all different from one another. Ex [ {1,1,}, {2,1}, {3,2} ] Arguments – first number of the pair Domain – whole set Values – Second number of the pair Range – set of values Classification of functions 1.

...functionality is mainly due to the many gestures created to manipulate this device. Primary functions will launch and control applications (apps), simply with a swipe of the finger or by tapping the screen. These gestures are only the tip of an iceberg and many more vastly wait to be discovered. The Nielsen Norman Group (2011) titled “Usability of iPads and Websites” gives a snapshot of the overall functionality of the iPad and shows its evolution from its conception to its current state. Let’s explore various gestures used to manipulate this device. Operability Between iPads, Apps, and Websites Designed with the user in mind, many devices are now interactive thus creating an easier and more enjoyable experience. The most basic iPad functions are achieved by swiping your fingers across the interactive screen. This gesture allows the user to scroll through pages or lists by simply touching the screen with the tip of your finger near the bottom and motioning it towards the top of the screen to swipe up or down. Although initially, your actions may appear to be counterintuitive, as the functions are opposite but think of it as your finger moving the screen. Let's get the most out of the tablet with commonly used iPad gestures. · Swipe up/down – Function used to scroll up and down web pages or menus. · Swipe left/right – Function is left or right like turning the pages of a book. · Pinch in/out – This zoom feature...

...locations in the UK, the storage capacity for this kind of product in the UK is limited. Therefore, in order to prevent the storage from exceeding the company’s storage capacity limits, as well as reduce the risk from supply chain (relying less on the overseas supply chain), sales department of ChocoHeaven has been trying to keep the demand into control by pricing the product differently according to different market tendency. To implement the corresponding price strategy and make it more effective, ChocoHeaven have closely monitored the monthly price and the corresponding sales of the ChocoMint bar over the past two years, which helps to discover the most suitable relationship between changes in volume of demand corresponding to changes in prices. Based on data provided, this report analyses relative changes in demand as price changes by using both statistics and graphs, trying to identify the most suitable model for the relationship between the price and demand. Subsequently, the model will be used to predict changes in demand corresponding to different prices, which contributes to achieve the goal of keeping demand for ChocoMint bar into control through special price strategy. Part1. Investigation of the relationship between the price and monthly demand Figure1.1 Monthly demand for ChocoMint and relative prices As can be seen from figure 1.1, generally monthly demand for the ChocoMint bar decreases as prices rise (although there is some...

...The Application of the Profit Function in a Business’s Growth Differential Calculus May 24, 2014 The application of calculus in a business is extremely important since calculus is considered as the study of changes. Its complexity in the study of changes has become one of the humankind’s greatest tool for analyzing changes in the marketplace. The profit function was created with the main purpose for businesses to understand how the changes in revenues and in costs would generate a profit or not profit at all. A profit can be generated when the amount of revenues is higher than the amount of costs. When a business starts, is normal to not gain any profit at all, in fact, most of the time, a business tends to lose money in its first year. However with that information, a business can analyze the money loss of that year and determine any gaps or holes that prevents the maximization of the profit and have a more prosperous result for the following year. For instance, if a company suffer a loss in profit, they can analyze the profit function to determine the main reason of why there was not a positive profit. If they see that the problem of the profit function was a low revenue then they can regulate the sale of products or services and price control, or if the problem lies in the cost function, they can adjust or lower the costs and expenses made by the business. The graph of a profit function can show at what time of the year the company tends to...

...development is required was planning and organizing. I have currently been experiencing a huge backlog in the various functions in my department. I have been struggling to plan my functions and that of my staff due to constant absenteeism, underperformance and training of new staff which we employed in my department and an existing backlog. The first step in attempting to resolve this problem was to have daily meetings with my manager, where I would provide him with feedback on the progress of the department and to discuss a plan of action to combat the backlog, and to get as much advise and guidance from him. I presented any suggestions that I received during the meeting, with my staff and encouraged my staff to give me feedback on how we can manage the functions more efficiently, especially the critical functions. A suggestion that I came up with was to draw up a timetable and allocate various functions to various timeslots- where the most critical functions would be allocated the most hours. I have struggled to implement this due to certain staff members that were underperforming. I approached my manager and he advised me of a different approach: he suggested that I handle all the functions in the following way- by running my files in such a way that I can calculate exactly how much work I have inside the 48hr turnaround time and outside the turnaround time- for each function. I then calculate how much staff I have available to work...

...b1 is recruitment rate of host population, λ1 is the transmission rate from vector to host, β1 is natural death rate of host population, γ is rate of recovery of host, a1 and a2 are the parameters which measure effects of psychological and social awareness. The parameter a1 is selected such that 1+a_1 V+a_2 V^2>0 for all V≥0. The parameter a2 is assumed to be positive. M(t) and V(t) denote the number of susceptible and infective individuals in vector population at time t, respectively so that N2(t) = M(t) + V(t). α2 is recruitment rate of vector population, β2 is natural death rate of vector population and λ2 is the transmission rate from host to vector. The parameter a3 measures the effect of hygiene and use of insecticide for vector control. Host and vector population can be differentiated as, d/dt N_1 (t)=α_1+β_1 N_1 (t) d/dt N_2 (t)=α_2+β_2 N_2 (t) The total host and vector population sizes are asymptotically constant and given as follows. lim┬(t→∞)〖N_1 (t)=α_1⁄β_1 〗,lim┬(t→∞)〖N_2 (t)=α_2⁄β_2 〗 So, we can suppose without loss of generality that N_1 (t)=α_1⁄β_1 ,N_2 (t)=α_2⁄β_2 for all t≥0. Therefore the dynamical system (2.1) can be reduced to qualitatively equivalent dynamical system (2.2) which is given by (dS(t))/dt=α_1-(k_1 λ_1 S(t)V(t))/(1+a_1 V(t)+a_2 V^2 (t))-β_1 S(t) (dI(t))/dt=(〖k_1 λ〗_1 S(t)V(t))/(1+a_1 V(t)+a_2 V^2 (t))-γI(t)-β_1 I(t) (2.2) dV(t)/dt=(k_2 λ_2)/(1+a_3 I(t)) (α_2/β_2 -V(t))I(t)-β_2...

...space with zero atoms consist of stones. 5. All empty space does not consist of stones. 6. Therefore, stones do not exist. To go even further, I can add another step in order to conclude that ordinary objects do not exist. The additional step would be that if ordinary objects exist, then stones must also exist. Therefore, ordinary objects do not exist. First we must see what objects exists and what objects occupy a position in space and time. Objects in the universe include planets, people, atoms, chairs, and the sun. They are all made out of parts and they are all composite objects. In order to explain the idea of composition we can say that the x’s compose a composite object if and only if the x’s, taken together have a function that none of them have separately, the x’s are physically bonded, and the x’s are inseparable. Nihilism supports Unger’s idea that stones do not exist because nihilism supports the idea that composition never occurs and therefore,...

...Samantha Poteet ENGWR 480 Professor Kiefer 31 October 2013 Little is known about Jakob von Uexküll, the author of A Foray into the Worlds of Animals and Humans: With a Theory of Meaning, other than his credentials and contributions. Uexküll studied zoology at the University of Tartu, known as Dorpat at the time, in Estonia from 1884 to 1889 (SUNY Press; Jakob von Uexküll Centre). Later Uexküll worked at the Institute of Physiology of the University of Heidelberg and at the Zoological Center in Naples, focusing on the behavior and interaction of living beings (SUNY Press; Jakob von Uexküll Centre). His written works were dedicated to the question of how living beings subjectively perceive their environment and how their perception determines their behavior, which is a dominant theme throughout A Foray in the Worlds (Jakob von Uexküll Centre). Uexküll argues that the spider builds its web before it has ever met a physical fly, therefore it is a representation of the spider’s primal image of the fly (159). Uexküll’s claim depends on three assumptions: (1) the fly is the prey of the spider, (2) the spider has a primal image of the fly, and (3) the web is the end product of the spider’s primal image. Though Uexküll’s claim may well have some merit, he presents an incomplete argument as his assumptions are insufficient and based solely on the evidence he offers, his argument cannot be accepted as valid. Uexküll’s first assumption is correct but also insufficient as it does...

It signifies what the emblem presently stands for. it is a assembly of convictions order about a exact brand. In short, it is not anything but the consumers’ perception about the product. it is the kind inside which a particular emblem is positioned in the market. Emblem likeness expresses emotional worth and not just a mental representation. Emblem image is not anything but aide degree organization’s feature. it is aide degree accumulation of contact and fact by individuals external to an association. It ought to focus aide degree organization’s operation and dream to any or all. The major parts of positive emblem image are- exclusive emblem reflective organization’s likeness, saying recounting organization’s business in short and emblem identifier carrying the key values. Brand image is that the overall impression in consumers’ mind that's formed from all sources. shoppers develop various associations with the brand. supported these associations, they form brand image. an image is made about the brand on the idea of subjective perceptions of associations bundle that the shoppers have about the brand.
