...Breaking Bad Was Realistic Allison Heyser Baker College Breaking Bad Was Realistic Perhaps some of what was written in Breaking Bad was over kill. A story of an average now middle class family, with a full time mother, and a father that works two jobs, goes haywire. Walter discovers that he can cook meth and make more money in a short time than he could in a full career as a chemistry teacher. Setting a dollar amount on his new career choice, telling himself he will quit when he reaches that amount. Yet every time he has a new reason to continue. All the while keeping his new life hidden from his family, essentially living a double life. It can be said that Breaking bad accurately portrayed today’s society in regards to families suffering from the economic decline, health care system, money laundering, greed and self-destruction from power. Success is sometimes measured in different ways and Mr. White’s story is an example of this fact. He started out as a successful scientist and business man with a promising future. He was persuaded to believe that the company he owned with is partner was failing and he decided to sell his portion to get out only to find that he would struggle to replace his former income. Working two jobs to support his family, neither of them what he imagined he would be doing with his master degree in Chemistry. He was over qualified by his standards to be a Chemistry teacher in a local high school by day and a...

...Audience Analysis COM 285 Audience Analysis Audience analysis is “the process of examining information about the listeners whom you expect to hear your speech” (Audience Analysis, para 1.). In this paper, I will describe a situation in which I am presenting quarterly sales information to a group of stakeholders, salespeople, managers and customers, at an in-person meeting. I will also discuss some of the audience characteristics that I must consider, along with finding the appropriate communication channels to use. I will also discuss some factors to consider when given the diversity of the group, and how to ensure that my message that I will be giving is effective. According to Locker and Keinzler (2008), the first step in analyzing an audience is to determine who the audience is. Identifying the audience and their motivations will assist you in learning how to reach them, and what messages to use to accomplish the task (Locker & Keinzler, 2008). Audience Characteristics Determine my Audience. The first step in developing my presentation, I will have to determine who my audience is. This is to ensure that I deliver an effective and clear presentation, with the focus on who is receiving the message. I am already aware that the audience consists of stakeholders, managers, salespeople, and customers. Therefore, given the audience, I can presume that I will be expecting a diverse group of people attending my presentation. Some of the...

...Task Name: Phase 4 Individual Project Deliverable Length: 4 Parts: See Assignment Details Details: Weekly tasks or assignments (Individual or Group Projects) will be due by Monday and late submissions will be assigned a late penalty in accordance with the late penalty policy found in the syllabus. NOTE: All submission posting times are based on midnight Central Time. Task Background: This assignment involves solving problems by using various discrete techniques to model the problems at hand. Quite often, these models form the foundations for writing computer programming code that automate the tasks. To carry out these tasks effectively, a working knowledge of sets, relations, graphs, finite automata structures and Grammars is necessary. Part I: Set Theory Look up a roulette wheel diagram. The following sets are defined: A = the set of red numbers B = the set of black numbers C = the set of green numbers D = the set of even numbers E = the set of odd numbers F = {1,2,3,4,5,6,7,8,9,10,11,12} From these, determine each of the following: A∪B A∩D B∩C C∪E B∩F E∩F Part II: Relations, Functions, and Sequences The implementation of the program that runs the game involves testing. One of the necessary tests is to see if the simulated spins are random. Create an n-ary relation, in table form, that depicts possible results of 10 trials of the game. Include the following results of the game: Number Color Odd or even (note: 0 and 00 are considered neither...

...GRE MATH FORMULAE Mixtures first.... 1. when you mix different quantities (say n1 and n2) of A and B, with different strengths or values v1 and v2 then their mean value vm after mixing will be: Vm*(n1 + n2) = (v1.n1 + v2.n2) you can use this to find the final price of say two types of rice being mixed or final strength of acids of different concentration being mixed etc.... the ratio in which they have to be mixed in order to get a mean value of vm can be given as: n1/n2 = (v2 - vm)/(vm - v1) When three different ingredients are mixed then the ratio in which they have to be mixed in order to get a final strength of vm is: n1 : n2 : n3 = (v2 - vm)(v3 - vm) : (vm - v1)(v3 - vm) : (vm - v2)(vm - v1) 2. If from a vessel containing M units of mixtures of A & B, x units of the mixture is taken out & replaced by an equal amount of B only .And If this process of taking out & replacement by B is repeated n times , then after n operations, Amount of A left/ Amount of A originally present = (1-x/M)^n 3. If the vessel contains M units of A only and from this x units of A is taken out and replaced by x units of B. if this process is repeated n times, then: Amount of A left = M [(1 - x/M)^n] This formula can be applied to problem involving dilution of milk with water, etc... EXPLAINATION TO THE ABOVE FORMULA when you mix different quantities (say n1 and n2) of A and B, with different strengths or values v1 and v2 then their mean value vm after mixing...

...Predicate Logic Example: All men are mortal. Socrates is a man. ··· Socrates is mortal. Note: We need logic laws that work for statements involving quantities like “some” and “all”. In English, the predicate is the part of the sentence that tells you something about the subject. 1 More on predicates Example: Nate is a student at UT. What is the subject? What is the predicate? Example: We can form two different predicates. Let P(x) be “x is a student at UT”. Let Q(x, y) be “x is a student at y”. Definition: A predicate is a property that a variable or a finite collection of variables can have. A predicate becomes a proposition when specific values are assigned to the variables. P(x1, x2, ..., xn) is called a predicate of n variables or n arguments. Example: She lives in the city. P(x,y): x lives in y. P(Mary, Austin) is a proposition: Mary lives in Austin. Example: Predicates are often used in if statements and loop conditions. if(x > 100) then y:= x ∗ x predicate T(x): x > 100 2 Domains and Truth Sets Definition: The domain or universe or universe of discourse for a predicate variable is the set of values that may be assigned to the variable. Definition: If P(x) is a predicate and x has domain U, the truth set of P(x) is the set of all elements t of U such that P(t) is true, ie {t ∈ U |P (t) is true} Example: U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} P(x): “x is even”. The truth set is: {2, 4, 6, 8, 10} 3 The Universal Quantifier: ∀ Turn predicates into propositions by assigning...

Introduction: The Need for Error Detection In communication systems, data transmitted over a channel will be exposed to transmission impairments. The most significant impairments are attenuation, delay distortion and noise. These impairments cause the received signal to be different than the transmitted signal which is not a desired situation. An error detection technique allows the receiver to determine if the received data is corrupted or not. 1.1 Error detection process To enable detection of errors, an error detection technique appends (n - k) extra bits to k data bits to be transmitted, creating an n bit frame. Appended bits are called redundant bits because they do not change the data bits and discarded by the receiver as soon as the integrity of the data bits is determined. Redundant bits (also called the checksum) are computed...

...Assignment 4: Funding Health Care Service Strayer University HSA 500 November, 2013 Introduction The essential business of the health care industry is the delivery of health care services. In the U.S., the health care industry is considered to be the largest service employer. Funding for the U.S. health care services consists of a mix of public and private payment sources. Medicare and Medicaid represent the two major health programs. Funding for Ambulatory Services The use of Ambulatory Care Services is common amongst most people. It has become an important element in the delivery of health care. For many, it has been viewed as the primary source of health care; offering an extensive range of services that don’t require overnight hospitalization. The services offered can be as complex as tests to and therapies or as simple as a minor cut. Traditionally in the U.S., ambulatory care services were provided in the offices of medical practitioners and in the homes of the patients. Presently, these services are performed in outpatient clinics, emergency rooms, and same day surgery centers. Ambulatory care has expanded within the health care system. This is due to the fact that it is less expensive than inpatient stays and less time consuming for patients. In comparison to inpatient patient procedures, outpatient procedures have been estimated to be 30% to 60% less in costs. Funding for Ambulatory care services began when the first surgical care center opened in...

...Many of us in recovery feel that consumer-run organizations (CROs) are treated by mental health care and advocacy leaders as recipients of their benevolence, instead of workers and individuals who deserve more than token roles in developing and delivering community mental health services. [...]the parallel problem of access was not addressed. [...]if a consumer does not have insurance (public or private) to begin with, parity is an academic discussion. Full Text Translate Full text Headnote Mental Health Systems engages public, raises funds, by deciding to tell its story In the business world, workforce development requires not only a clear vision of where you want the enterprise to go and how you propose to get there, but also who the best people are to get you to the destination. As we wring our hands about the lack of funding to provide high-quality behavioral healthcare for all Americans and the chronic shortage of qualified professionals to deliver needed services, we seem reluctant to pursue either innovation or adequate investment in transforming the service delivery system. Yet, even amid these struggles, people in recovery from serious mental illness - in the evolving role of consumer-providers - are not just playing bit parts in this transformation, but are emerging as producers, directors and stars of the "show." Many of us in recovery feel that consumer-run organizations (CROs) are treated by mental health care and advocacy leaders as recipients of...

...United States. There has been an increase in the number of physicians in the last four decades; the increase represented a 218 percent increase (Williams, & Torrens, 2010). In spite of the increase in the number of physicians and the prediction of a surplus, the focus and physician requirement for the public has shifted. The shift in medical practice structure from an efficient formation has put pressure on the demand for more physicians. Physicians and patients are preferring choice over efficiency. The three reasons that there may be a physician shortage rather than a surplus in the United States is that physicians favor a more “controllable lifestyle”, the proportion of first year medical students who are women reached parity to male students, and the unusual growth in population requiring physicians (Williams, & Torrens, 2010). The physician’s preference now favor a more...
