Project Management the First Activity Scheduled Is

Project Management The first activity scheduled is activity 2, because it has the minimum slack. Then activity 1 is scheduled. Activity 3 is delayed one period, which reduces slack to zero. From this, activity 5 will also be delayed one period, reducing slack to zero. The remainder of the activities will be scheduled in order, subject to delays. Therefore, the order in which the activities are scheduled is now 2,1,3,4,5,6. The activities that are critical are those in which there is the least, or negative, slack. The critical activities therefore are 2,3,5,6. The slack for activity 1 is now 0. The slack for activity 4 is now 2. The slack for activity 5 is now 0. Period Activity Changes 0-1 Schedule Activity 2 as per minimum slack rule 0-1 Schedule Activity 1 0-1 Delay activity 3 ES to period 1, reduce slack to 0 0-1 Delay activity 5 ES to period 6, reduce slack to 0 1-2 Delay activity 3 ES to period 2, reduce slack to -1 1-2 Delay activity 5 ES to period 7, reduce slack to -1 1-2 Delay activity 6 ES to period 11, reduce slack to -1 2-3 Delay activity 3 ES to period 3, reduce slack to -2 2-3 Delay activity 5 ES to period 8, reduce slack to -2 2-3 Delay activity 6 ES to period 12, reduce slack to -2 3-4 Schedule activity 3……

Survey of Mos-Gated Thyristors

¶ … MOS-Gated Thyristors Power semiconductor switches have been widely applied in power electronics. However their low usage in pulse power circuitry is due the apprehension that small scale pulse operations might lead to early breakdown. Thyristors have proven to be advantageous in this regard due to their high blocking voltage coupled with an elevated potential to carry steady state current. This paper presents a survey of 7 thyristor structures (Emitter Switched, Base Resistance controlled, Dual Channel EST/BRT, Emitter controlled, Dual gate, Insulated base ECT and floating Base). [1] The benefits of high input impedance have caused the fabrication of new MOS gated bipolar devices. IGBT (Insulated Gate Bipolar Transistor) is one such device which have their on-state features superior to MOSFET. Thyristor-based devices such as EST (Emitter Switched Thyristor) and BRT (Base Resistance Thyristor) demonstrate how the conduction traits can be enhanced even further. They have turn-off times in the range of 10 ?sec.[2] Emitter Switched Thyristor (EST) EST is composed of a vertically placed thyristor within a succession of n-channel enhancement mode MOSFET's. The operational mode is usually forward blocking with the gate voltage at cathode potential. A positive gate bias employed on the device turns it on. This has to be over the threshold voltage of the NMOSFET as the anode potential is maintained positive with regards to the cathode. Bringing the gate voltage down to zero switches the device off. The EST structure shows the development of a parasitic thyristor due to the integration of a lateral NMOSFET with the thyristor P-Base. [2] Base Resistance Controlled Thyristor (BRT) A BRT is composed of a vertically placed thyristor with an adjoining MOSFET. An channel MOSFET is created on the P-base surface in amid the N+ emitter and N- drift regions and is utilized to turn the device on. AP channel MOSFET with the P-base and P+ diverter regions acting as its source and drain is used to turn the device off. The on-resistance of the P. Channel MOSFET restricts the maximum controllable anode current density. [2][3] Dual Channel EST/BRT The dual channel EST-BST is a capable alternative to the IGBT (Insulated gate bipolar transistor) for applications such as Uninterrupted Power Supplies and Lighting ballasts. It incorporates properties such as high voltage current saturation, lower on-state voltage drop associated with the thyristor structure and BRT like enhanced turnoff potential. an-Channel MOSFET turns it on while a P-Channel MOSFET…

Moi, Tituba SORCIERE - NOIRE De Salem; Resume Et

Moi, Tituba Sorciere…Noire de Salem; Resume et Analyse La nouvelle francaise intitulee "Moi, Tituba Sorciere…Noire de Salem" est une histoire comme il y en a deja beaucoup trop. L'action se deroule a une epoque ou les personnes de couleur etaient percues de maniere negative et, plus souvent qu'autrement, utilises en esclavage. Cette epoque du passee a vu beaucoup d'horreur et de violence; cette nouvelle decrit les inhumanites du temps tout en offrant un point de vue romanesque aux lecteurs. Resume L'histoire se deroule au 17 eme siecle et debute a la Barbade. La Barbade est une des petites iles des Antilles et est tres connue pour son implication avec l'esclavage des personnes de couleur noire. Cela etant dit, Tituba est une jeune esclave originelle de cet endroit et ne connait vraiment rien de mieux que sa situation presente. Tituba est presentee comme etant une jeune fille ne recevant pas beaucoup d'affection maternelle. En effet, sa mere Abena a donne naissance a Tituba suite a un viol subit sur un bateau anglais. Abena reste donc partialement froide a l'egard de Tituba, comme ci celle-ci n'etait pas la bienvenue dans sa vie. L'amant d'Abena, Yao, semble etre une figure paternelle acceptable pour Tituba qui trouve un certain reconfort aupres de lui, a defaut de trouver ce reconfort aupres de sa mere. Abena aussi est une esclave, comme la majorite des femmes noires de l'epoque. Un jour, alors que son maitre blanc tenta de se forcer sur elle, Abena lui infligea une blessure; le maitre, hors de lui, ordonna de pendre Abena. Comme s'il ne fut pas suffisant pour Tituba de perdre sa mere, Yao commit un suicide peu de temps apres, attriste par la mort de sa bien-aimee. Entre alors Man Yaya, une vieille dame qui eduque Tituba sur les secrets et particularites de la guerison et des plantes. Tituba et Man Yaya vivent une vie spirituelle riche, communiquant avec les morts, jusqu'au deces de Man Yaya. Tituba, seule une fois de plus, se retire dans les bois et se construit un abri pour vivre librement. Cette liberte ne fut que de courte duree car Tituba decida de retourner a l'esclavage par amour pour John Indien, un autre esclave au service d'une dame nommee Susanna Endicott. Comme le mot circule que Tituba fut elevee par une sorciere, Man Yaya, Endicott humilie Tituba a plusieurs reprises et la menace, poussant Tituba a souhaiter…

Theory a Set Can Be Defined as

¶ … Theory A set can be defined as a collection of distinct objects. A subset is a smaller set that lies at least partially within the larger set. Thus if Set a = { 1, 2, 3 } then a subset would be { 2, 3 }. A proper subset is one that is entirely contained within the set. The above example has subset B. that is a proper subset of Set a. The complement of a set is that which lies outside of the set. In the example above, the complement of Set B. In a would be { 1 }. Unions are made when two or more sets are taken together and includes all things that are in all of the union sets combined. If Set a = {1, 2} and Set B = {2, 3} then the union of sets a and B. would be { 1, 2, 3} The intersection is comprised of all things that……

Limiting a Researcher's View of

Contrast this with the quasi-experimental design, which has significant difficulties with internal validity. A quasi-experimental design "is one that looks a bit like an experimental design but lacks the key ingredient -- random assignment" (Trochim, 2008, 210). Why would a researcher, who values internal validity, then choose a quasi-experimental design, that specifically lacks in internal validity? The reason is that experimental designs are not always the most effective. They're subject to social threats of internal validity, and have difficulties with external validity (Trochim, 2008, 188). An experimental design is "intrusive and difficult to carry out in most real-world contexts," and is basically an "artificial situation" created to "assess [a] causal relationship with high-internal validity." Resultingly, there are difficulties in generalizing the findings to the real world. Alternatively, certain types of quasi-experimental designs are some "of the most intuitively sensible designs around" (Trochim, 2008, 210). This is because random selection is often not logical or possible. For example, say we wanted to understand the effects of a certain type of treatment on both developmentally disabled adults and adults that were not developmentally disabled. Random selection, or an experimental design, would be impossible here, because we already have our two groups; they're dictated by the difference. The basic reasons one might choose an experimental design or a quasi-experimental design has to do with, I think, resources, and what exactly is being tested. I feel that there is no design that is "better" or "worse" -- applying those labels would not make any sense at all here, because every experiment has a different aim. What is good for one experiment may be bad for another. The most important thing, I feel, is……

Measures -- Central Tendency & Variability Decision-Making

Measures -- Central Tendency & Variability Decision-making using measures of central tendency and variability In order to determine which group of workers would have higher levels of manual dexterity, and would therefore have a lower chance of breaking significant inventory, measures of central tendency and variability would help the decision-maker come up with the most efficient solution to this problem. Running the data for the two groups below, the following were the calculated measures of central tendency (mean and median) and variability (variance and standard deviation): Group a Group B MEAN MEDIAN VARIANCE STD DEV Looking at the measures of central tendency, the values for mean are the same for both groups. Thus, it is important to compare the two groups based on the second measure of central tendency, which is the median. Comparing the two groups, Group B. has a higher median, which is also true when the median value is compared against the mean. This indicates that most likely, the distribution of scores is negatively skewed, which means that the frequency for workers increases as the level of manual dexterity also increases. This gives the decision-maker a good basis for choosing Group B. over a, but to ensure that the decision-maker has indeed made the correct choice, it is important to look at the variability of the scores within each……

Temperance Dr. Stockmann Faces a Series of

Temperance Dr. Stockmann faces a series of dilemmas in the play An Enemy of the People. He discovers that the tannery is polluting the baths on which the townspeople have built their hopes. There is little equivocation on his part as to whether or not reveal this, demonstrating that he has little sense of dilemma with respect to this truth. The relevant authorities and indeed the townspeople as a whole disagree with his assessment, since the revelation makes the townspeople the losers instead of what would end up being hapless tourists. Stockmann's dilemma then shifts towards going along with the will of the masses or facing ostracism. He ultimately chooses the latter, becoming something of a martyr to this cause. Temperance in this situation would have been to back down in the face of the town's resistance to his revelation and proposed solution. Dr. Stockmann, however, finds that he has already chosen the path of temperance only to see it fail. In the face of this failure, he can no longer remain civil about the matter. The play ends with Dr. Stockmann's statement that "the strongest man in the world is he who stands alone." This clearly……

Peanut Butter and Jelly Sandwich to Make

¶ … Peanut Butter and Jelly Sandwich To make the perfect peanut butter and jelly sandwich, you will need one jar of peanut butter -- creamy or crunchy, depending on your preference (as a snack, I prefer the creamy, but for meals the crunchy gives the sandwich a more substantial feel), as well as one jar of strawberry (yes, strawberry only) jelly, two slices of white bread (crusts on), and a standard butter knife. Start by placing the two slice of bread side-by-side on a plate, counter, or other surface in front of you. Sandwich making without a surface is possible by shifting the various jars and slice of bread around n your hands and under your arms (when not in use), but this should only be attempted by those already proficient in the basic procedure. So, with the bread in front of you, rounded sides furthest away, begin by opening the jar of peanut butter and using the knife to withdraw at least enough……

Philosophy First of All, Because Knaves Always

Philosophy First of all, because knaves always lie, the words of the always-truthful oracle must be consulted first. It says that if there is one knight, there are at least two knights, and if Sam is a knight, then Alice is a knave or Bob is a knight. The oracle states that if there is one knight, at least one of the two must be a knight. The oracle also says that of Sam is the knight, either Alice is a knave or Bob is a knight. Now the words of the knights and knaves must be consulted. Bob says that "Either Sam or Alice is a knave!" So, from what Bob says: if Bob is a knight and knights always have a partner, either Sam is a knight or Alice is a knight. But Alice said that at least one of them is a knight, and if Alice was a knave, that would have to be a lie. So this means that if Bob is a knight, Sam is the knave and Alice is also a knight. If Alice is a knave, then all of them would have to be knaves, to make her statement false. Bob said that either Sam or Alice are knaves, so he could be a knave, as if they were all knaves, that would make his statement false as well. Sam cannot be a knight because to make the oracle correct if Sam is a knight than Alice is a knave or Bob is a knight, so then all three must be knights. But Bob said that either Alice……

Appearance and Reality in Shakespeare's Hamlet One

Appearance and Reality in Shakespeare's Hamlet One example we see of reality vs. The imagined is when Hamlet first encounters the ghost. This scene is powerful because it sets the mood for the rest of the play. He cannot decide if the ghost is really the ghost of his father or something worse. He calls the ghost a "goblin damned" (I.iv.44) but then later, he comes to the conclusion that the ghost might not be evil after all and calls it, "King, father, Royal Dane" (Shakespeare I.iv.50). Another scene where things are not quite what they seem to be is when Hamlet feigns his madness when he is around Polonius and Polonius comments that Hamlet is not himself. (I.iii.124) the appearance of madness can also bee seen in the following scene when Hamlet is with Ophelia. Here, his is faking his madness that he crushes Ophelia. He certainly doe not seem like the man that was once in love with her. He admits to loving "her once" (III.i.125) and then he……

Lady Macbeth William Shakespeare's Play, Macbeth, Illustrates

¶ … Lady Macbeth William Shakespeare's play, Macbeth, illustrates how we all need somebody to help us along the way to becoming who we are. Macbeth was no doubt a successful man but he would never have become the man he did without Lady Macbeth. Whether or not he ever knew it, Macbeth needed Lady Macbeth to accomplish the things he did. She supported him and his ideas, provided strength and urgency when necessary, and essentially made him the man he became through careful and calculated manipulation. Lady Macbeth was the spine Macbeth needed in times of weakness and his love proved to be a blind spot where his wife was concerned. Macbeth was a good man but he did not have what it took to be king. His wife knew this and was prepared to do what she had to in order to help him reach their shared goal - the crown. She also knew that it was highly unlikely that a "good guy" would make it to the throne. Wayne Booth claims that Lady Macbeth "fears his human kindness" (Booth 194). Lady Macbeth wanted nothing to stand in their way. She tells her husband: Glamis thou art, and Cawdor; and shalt be What thou art promis'd. Yet do I fear thy nature; It is too full o' the milk of human kindness To catch the nearest way; thou wouldst be great, Art not without ambition, but without the illness should attend it; what thou wouldst highly, That thou wouldst holily; wouldst not play false, And yet wouldst wrongly win; thou 'dst have, great Glamis, That which cries, 'Thus thou must do, if thou have it. (Shakespeare I.iv.16-24) This statement allows us to see two things about their relationship. First, we see how in tune to his Macbeth's psychological composition. Second, we see how she knows she has control over him. From this we can understand how Lady Macbeth is very aware of Macbeth's psychological composition and is completely confident in herself to influence him. Stephen Greenblatt maintains that spousal intimacy in Macbeth is "terrifying" (Greenblatt 138). Lady Macbeth uses her "sexual taunt" (138) to get her husband to do what she wants him to do. She plays on Macbeth's "innermost fears and desires" (139). What is remarkable about their relationship, he continues, is the "extent to which they inhabit each other's minds" (139). Harold Bloom agrees with this…

Time Series Analysis Stationarity

¶ … Malicious network intrusion is typically associated with specific data trends and data alerts through which network attacks can be detected and mitigated. The evaluation of those data to illuminate identifiable trends relies on sequential observation at regular time intervals. This time-series-process approach to data analysis can apply either to single-series (i.e. univariate) observations or to multiple-series (i.e. multivariate) observations. Stationery time series analysis is particularly useful in predictive modeling, but requires statistical uniformity of the observations (i.e. random variables) over time. Time series analysis is dependent on constant variance about a fixed mean. Moreover, that mean must be a constant and not a function of time shift, making it "weakly stationary." Time series analyses that satisfy the applicable criteria allow IT security to detect and identify the nature and significance of non-randomness in data. Time series modeling exploits data trends in the past to formulate predictive models of future behavior. In principle, this is made possible by permitting the dependent variables to reflect past data and past independent-variable……

Introductory Algebra

¶ … Algebra Many times when purchasing a service there are choices to make. This man is totally confused and frustrated about his options. One example is phone service: A telephone company has a choice of two plans. Plan A - $30 per month and $.05 per phone call and Plan B - $20 per month and $.10 per phone call. Which is the best plan for you? By the end of this discussion, you will have demonstrated your ability to: Explain two possible plans that provide the same service The first plan is saying that there is a fixed cost at $30 per month and then there is a variable cost associated with it which is $0.05 cents per phone call- this is a variable cost because it is dependent on how many phone calls are actually made. The second plan is saying there is a fixed cost of $20 per month and then the variable cost associated with this is $0.10 per call- this is a variable cost and is directly dependent on how many calls are actually made by the user.

Calculated F-Measures, All of the Transformation Methods

¶ … calculated f-measures, all of the transformation methods improved the performance of most classification methods, though in many cases performance did not vary considerably between untransformed (i.e. original) and transformed data or between the varied transformations and classification methods that were applied to the various data sets. There are certain notable exceptions, in particular data sets for which specific classification systems seemed wholly unsuited regardless of any transformation method applied, and also a few cases in which a transformation method greatly improved the performance of a classification method. The NTP2 data set and the DARPA data set both resulted in lower overall performance across transformation and classification methods, yet there is a substantial spread in the performance of transformation and classification methods. For the NTP2 data set, the MLP classification system was the strongest performer overall, and performance was significantly improved for several classification systems through use of the PPFSCADA transformation method -- in the case of the SVM classification method, performance was almost doubled following this transformation. The PPFSCADA transformation method generally had greatest positive impact on performance across data sets and transformation methods, though it actually greatly reduced performance when the 7NN classification method was applied to the NTP2 data set. Performance on the DAPRA set was somewhat higher on average than the NTP2 data set, though the MLP classification method showed especially poor performance with this……

J'ai etudie francais au lycee et aussi a l'universite, mais je vois maintenant que je n'etais pas preparee pour la vie en France. Je vais vous expliquer ma vie quotidienne et a quel point cela est different de ma vie aux Etats-Unis. Je partage un petit apartement avec deux amies de l'universite, qui sont americaines comme moi. L'apartement tient trois petites chambres et seulement une salle de bain. Ce qui est bizarre est le fait que il n'y a qu'une seule WC! Quand je vivais aux Etats-Unis je vivais avec deux amies aussi mais nous avions trois WC aussi. Le pire c'est quand nous reveillons le matin et tous les trois nous essayons de nous doucher mais il y a quelqu'un d'autre dans la douche! Apres, je vais a l'universite.

Accuracy on Semiboost Are Noticeably Higher Than

¶ … accuracy on SemiBoost are noticeably higher than any other method with more than one value being above 96 including two values over 97 and a third that was over 98. There was a range of about 2 for the accuracy overall on SemiBoost. SemTra has nothing above 96 while PGM has nothing above 95. BGCM and ORTSC are all 92's and 93's. As for standard deviations, Semi-Boost ranges from 0 to 2 on the SD range while SemTra does much the same thing except for a few values above 2. PGM ranges from 2 to 5 as does BGCM with the largest BGCM value being a smidge over five standard deviations. ORTSC ranges from 3 to 6 standard deviations. In short, as the table progresses from left to right, the accuracy values go down and the standard deviations tend to go up. The standard deviations rise in number as one goes from left to right in the table but the actual width of the range of the values varies little overall, almost always being roughly 2 standard deviations for each set. In a similar way, the accuracy figures do the opposite as they tend to go down as one goes from left to right. The Semi-Boost figures are all 95+ but none of the ORTSC figures are……

Microeconomics the Following Is the

Microeconomics The following is the complete elasticity chart. There were a couple of blanks where the denominator was zero that did not yield a usable result: Price Demand Total Revenue % Price % Quant Elasticity #DIV/0! #DIV/0! Exercise 1a) If the initial price is $400, then demand is 10000 - (400)(10) = 6000. If the price is $500, then the demand is 10000 -- (500)(10) = 5000. The elasticity between these two prices is as follows: % change in demand / % change in price The change in demand is (4000-5000)/(5000) = -20% The change in price is (500-400)/400 = 25% The elasticity between $400 and $500 therefore is -20/25 = -0.8 The concept is elasticity reflects the degree to which the demand for a good is affected by the price of a good. To calculate elasticity, you need a change in price and a change in demand. When the price changes, elasticity tells us how much demand for that good is expected to change. In this case, every additional dollar is price will result……

Machines & Marble Drop the Simple Machines

¶ … Machines & Marble Drop The Simple Machines and Their Use in an Inclusive Marble Drop Toy A force is required to move an object. The force applied in and through the distance moved is the work done. Machines are generally used to change the force necessary to move an object, though the overall work is the same neglecting wasted friction. There are fundamentally six simple machines out of which more complicated machines are composed. They are the inclined plane, the wedge, the screw, the lever, the wheel and axle, and the pulley. The inclined plane allows one to push an object up and along the plane with less force than directly raising the object. The wedge is one or two backed-to-back inclined planes. it's used to pry two things apart. One applies a force to advance the wedge which splits wood or raises a heavy object perpendicular to the applied force's direction. The screw is a narrow inclined plane, called a thread, wrapped around a cylindrical core. Turning the screw core advances it as the thread slides through material or along a guide depending on the screw's purpose. The lever is a stiff rod that rotates about a pivot point called a fulcrum. Forcing down on one end of the lever causes the other end to rise while lifting an object due to the pivoting action of the fulcrum. The greater the forcing end's distance is from the fulcrum compared to that of the object's distance, the less the force needed to lift the object. The wheel and axle is composed of a larger radius disk with a smaller radius axle fixed through its center. As the two parts turn in unison, the longer distance traversed at the disk's radius corresponds to a shorter distance at the axle's radius. The force needed to turn the assembly at a given torque (twisting strength) is least at the wheel's rim compared to the force needed at the axle's rim in inverse relation to their respective radii. The simple pulley uses a rope riding along the rim of……

Irrationality of Man in "The Tell-Tale Heart"

Irrationality of Man in "The Tell-Tale Heart" Edgar Allen Poe is one of the most creative writers when it comes to expressing the irrationality of man. He does this by creating colorful narrators that pull us in with interesting dialogue and questionable actions. He emphasizes the irrational by placing readers into the mind of a man that thinks he is rational by all accounts. Readers want to believe the narrator is sane because he is human. Poe creates suspense by bring the narrator's irrationality into the story slowly. The narrator in this tales wants to be rational and we want to believe he is rational but as the story goes on, we realize we are dealing with a very unstable man. By the end of the tale, we are afraid for ourselves because we do not know the limits of our own minds. Poe uses the human mind to create suspense and, eventually, horror to entertain readers. Poe amplifies fear in readers by putting them into the mind of the narrator. In "The Tell-tale Heart," we know the narrator's thoughts and we believe he is not crazy, mad, or irrational because he tells us he is not. We give him the benefit of the doubt because we want to believe him but also because he seems rational at the beginning of the story. In the beginning of the story, we find the narrator seems to have his senses together. He boasts about his mental acuity, saying, it "sharpened my senses -- not destroyed, not dulled them. Above all was the sense of hearing acute" (Poe 189). He is convinced that the things that make him appear irrational are making him smarter and sharper than usual. The power of the mind is pulled into question with interesting behavior. Poe uses the very thing that makes his narrator seem rational to prove him irrational. It is the same dialogue but it changes as the story progresses. The narrator becomes more unstable the more he talks and this creates more drama for the reader. The narrator's motive for killing the old man is an "Evil Eye" (189), which is the first clue that something might be amiss with our narrator. This instability increases suspense as the story moves forward. Furthermore, the more we read, the more irrational this man becomes. When he says he hears the old man's beating heart, we know he…

How About a Kiss Exercise

¶ … KISS? Jennifer was very confused about John's reaction. Wasn't it he who suggested that they should consider seeing other people? Wasn't it he who said things were moving too fast? Now, he seemed genuinely hurt, even angry, that she made plans to go out with someone else; and it was just a casual drink. The fact that John was obviously pretending that he was annoyed about something else instead only further complicated things. She wondered why men are so afraid to acknowledge their feelings. It wasn't like they'd made definite plans for Saturday anyway. Wasn't he a big Seinfeld fan? Isn't an "implied" date for every Saturday night (along with any feminine hygiene products or clothes left at his place) one of the hallmarks of the serious relationship that he'd said he wasn't quite ready for in the first place? It was only a few weeks ago that the two of them……

Efficient Portfolio

Efficient Portfolio The weighted average expected return under the new scenario will be 14%. This is calculated as follows: The standard deviation of returns under the new scenario is 24.5. We calculate the difference between each potential return and the mean. Thus, (44-14) = 30; (14-14) = 0, and (14+16) = 30. Each is squared, and then the squares are added together. So 302 = 900. This means that the sum of squares is 900 + 0 + 900 = 1800. This is divided by the number of data points, as follows: This is the variance. To obtain the standard deviation we take the square root of 600 as follows: The expected return is .333(12)+(.333)(4)+(.333)(-5.5) = 3.5 The standard deviation therefore is 12.38. With half in T-bills the expected return is 3.75%. The standard deviation is therefore 6.015. The expected return improves because you reduce the downside risk with the T-bills. This also reduces the variability of the portfolio as well. Problem The expected return of this portfolio is as follows: (.5)(15)+(.4)(10)+(.1)(6) = 12.1%……

Exercise on the Use of Significant Detail

¶ … Exercise The harsh rays of the sun hit my skin with its indictment. The wind whispered harsh and hot non-words to my tortured skull. "You did this," it seemed to say. "And you will pay." The pavement under my feet was harsh as I tried to but could not run. If I run everyone will see and guess terrible things. They will know the unimaginable. My mind wanted to turn my feet back. My heart wanted to move them forward. My feet were confused and listened to neither. I stood still under a big oak tree and simply breathed. How could I? Was this really the thing that I had become, or was it part of some terrible dream? The oak tree sheltered me from the sun's truth for a while. I would rest here. It was a good spot with the park forming a sharp contrast against the busy street. I had never before wondered why they would put a park so close to a busy intersection. Maybe it was someone's skewed sense of the aesthetic. But who was I to judge the aesthetic or the malfunction of sense? I sat on a hard bench and the……

Native American Tricksters Tales

American Literature Native American Tricksters Tales The "Bungling Host" contains a couple of good lessons about how people should not behave. The firs lesson is about how one should not always want to be just like everyone else. The rabbit watched the bear prepare his meal and when the bear came to his house for dinner he wanted to prepare his meal in the same way. But when he slit his belly he injured himself. If the rabbit had just prepared his dinner the way that he had always done he would not have ended up getting injured. The second lesson that this tale teaches is that of how things are not always as they appear. When the rabbit got injured and the bear went out to seek help, he brought back a buzzard. The buzzard had assured the bear that he could help the rabbit to get better. The bear trusted him to be telling the truth. The buzzard on the other hand, had no intention of helping the rabbit, but indeed had ulterior motives of having the rabbit for……

Validity & Reliability in Research Validity and

Validity & Reliability in Research Validity and reliability are two concepts considered critical in every research study, be this study under the qualitative or quantitative research design. These concepts must be disclosed and discussed in detail in every study, since they serve as the foundation of the credibility and 'strength' of the data -- that is, how strong the study's data is in answering the research questions and objectives, and how the data is 'flexible' enough to be used to answer, if not wholly, then partially, questions and objectives of other studies (related in some way to the issues covered in the first/original study). Qualitative and quantitative research designs utilize different methodologies or data collection methods; therefore, each research design uses different techniques in testing for validity and reliability. Conceptually, validity is defined as follows: "[v]alidity determines whether the research truly measures that which it was intended to measure or how truthful the research results are" (Joppe, 2000 in Golafshani, 2003:599). Reliability, meanwhile, is the "extent to which results are consistent over time and an accurate representation of the...population under study...and if the results of a study can be reproduced under a similar methodology" (Joppe, 2000 in Golafshani, 2003:598). Under the quantitative research design, validity and reliability are tested using different techniques. It is crucial to test for both because a study's data must be proven as valid and reliable before the end-user considers the importance of the study's results and recommendations. In quantitative studies, validity, on one hand, is tested through content, criterion, and construct validity tests. Content validity determines whether the construct used in the instrument is correctly defined and operationalized. Criterion validity, meanwhile, looks at how a construct "can accurately predict...the construct being measured." Lastly, construct validity ensures that……

Operate a Cappuccino Maker. Unscrew the Lid

¶ … Operate a cappuccino maker. Unscrew the lid on the top of the cappuccino maker. Add the desired amount of water. The carafe is marked with two lines, indicating the amount of water needed for 2 shots or 4 shots of espresso. If you intend to foam milk, fill 2 centimeters above the fill line. Ensure that the lid is screwed on tight. Also ensure that the steam knob is fully closed. Ensure that the cappuccino maker is plugged in. Fill the coffee holder with the desired amount of ground coffee. The holder is marked with two lines, indicating 2 shots or 4. Do not exceed the line for the desired amount of espresso or the results will be below expectations. Attach the coffee holder to the machine by placing the round end underneath of the overhang on the machine. There will be a matching round end on the underside of the overhang. The coffee holder will go into the round end at a 45 degree angle to the front of the machine. Then, move the coffee holder until it is in line with the direction of the overhang. There will be a click when the coffee holder is correctly inserted, and it will stay in place when you let go. At the bottom of the coffee holder are two spouts. Place the carafe underneath of these two spouts. Turn the cappuccino maker on by flicking the red button that is located at the base of the machine on the left side. The light will illuminate to indicate that the machine has been turned……

Iago in Shakespeare's Othello

Othello Iago in Othello William Shakespeare's Othello is essentially a play about human passions, which, when unleashed, can be blind and destructive. Iago can be considered the most important character in the text, as it is him who manages to manipulate all the characters in the play by making use of their own weaknesses, so as to make them serve his own purpose of revenge. Iago's motivations are multiple. He repeatedly states his hate for "the Moor," and sets to destroy him and the other characters in the play. To achieve this, Iago makes use of the passions that he intuitively perceives as very prominent in the other characters: he uses Othello's love for Desdemona and manages to drive him to believe she is unfaithful, he uses Desdemona's generosity to determine her to speak to Othello in behalf of Cassio and so on. Thus, love and hate are the main human passions, but, from both of these, a third passion is often born: jealousy. Iago triggers Othello's jealousy, and as he does so, he is motivated by his own jealousy. In Othello, Shakespeare shows how jealousy drives men to acts normally unconscionable. Jealousy motivates Iago to lie, cheat and steal his way to the chief lieutenant's position. It is not mere hatred as such that motivates Iago therefore, but his jealousy and the infernal pleasure he derives from manipulating the others. As such, Iago is a double faced character who dissimulates his own jealousy and passions to manipulate the other's feelings. Shakespeare's play is interesting because of the way in which the jealous Iago manages to manipulate the jealousies of the others. First of all, Iago's enjoyment at manipulating the others……

Technical Writing - Results Technical Instructions for

Technical Writing - Results TECHNICAL INSTRUCTIONS for SALVAGING AUDIO CASSETTES AFTER the MAGNETIC TAPE HAS BEEN TORN or PARTIALLY DESTROYED USABILITY TESTING MEMORANDUM The design of the instructions was fundamentally sound, enabling most of the test subjects to achieve the objective of salvaging the cassette tapes so that it was capable of being played after repair. Those test subjects who failed to achieve the objective experienced two categories of difficulty, one of which is capable of redress in a revision to the instructions and the other of which is capable of improvement with the experience of additional trials and repetition only but not by any technical revisions to the original instructions. Significantly more test subjects who failed by virtue of the technical aspect also failed the apparent experience-related operational element more often. Additionally, most technical failures were resolved on a second trial, while fewer than half the operational failures were resolved on a second trial suggests that individual competence and concentration on task execution played some role in the technical aspect of failures as well. Definitions: Success in the tested task was defined as restoring the damaged cassette cartridge to playable condition. Technical Failure was defined as malfunction upon playback as a result of deficiencies identified in the technical instructions. Operational Failure was defined as malfunction upon playback as a result of failure to follow the instructions and/or failure resulting from the subject's inability to successfully execute the instructions for reasons related to difficulty manipulating the tape cartridge components in a manner conducive to its successful repair. Chart #1- Results of First Trial: Total # Test Subjects in Testing Group: 18 Successful Completions: 9 Technical Failures: 4 Operational Failures: 5 Combined Technical and Operational Failures: 3 Chart #2- Results of Second Trial: Successful Completions on 2nd Trial after Technical Failure: 3 of 4 Successful Completions on 2nd Trial after Operational Failure: 3 of 5 Successful Completions on 2nd Trial after Combined Failure: 1 of 3 Successful Completions on 2nd Trial after Initial Success: 9 of 11 Detailed Analysis: Technical failures occurred when subjects successfully completed all the individual steps detailed in the technical instructions but experienced failure related to secondary magnetic tape breakage on the playback attempt. Failures of this type were universally attributable to failure of the technical instructions to provide more precise instructions for splicing the magnetic tape. Operational failures occurred in two specific types: (1) where subjects…

Informal Poem Exercise

¶ … Flames of my Father The object that I have in mind burns brightly when you light it, emits a warm and comforting glow, can be colorful, is traditionally designed as slim, can possibly give off a pleasant scent when lit (aromatherapy). It is multi-faceted with different layers, and has a flame. I wanted to compare a candle with my father, because I cannot think of any other person who resembles a candle (figuratively speaking, of course). Like a candle, every time my father enters a room, he lights it up by being an incredibly kind, decent, and social person who is not afraid to talk to anyone, not even total strangers. His warm-hearted personality he inherited from his mother, my paternal grandmother. Candles are traditionally slim, and my father happens to be a naturally slim person (it runs on his side of the family). My father has many layers like a candle, but can also be rather predictable day-to-day. Most……

Personal Quality, Talent, Accomplishment, Contribution or Experience

¶ … personal quality, talent, accomplishment, contribution or experience that is important to you. What about this quality or accomplishment makes you proud and how does it relate to the person you are? Not Heartbreak Hill of the Boston Marathon, maybe, but it's broken the willpower of many runners. the Junior Varsity National cross-country championship. SAC invitational. Famous for being one of the biggest invitationals in the nation. Famous for boasting a course that is made up of three hills, sloped as steep as a staircase. The first hill is almost perpendicular to the ground. The second is the worst of the three. That is the most difficult way to structure a course. The hardest hill rises up before the runner, just after he's lost his freshness, but he can't see the finish line. I am the captain of my team, and my mind is filled with thoughts, not just of my own desire for victory, but how many times I talked my Arcadia teammates through hard practices with inspiring words. How can I let them down? Everything I told them about perseverance and persistence will seem like a lie, if I don't run faster.……

Percentages Can Often Be a Difficult Concept

Percentages can often be a difficult concept to grasp for students, particularly if they have only recently learned proportions. Fortunately, there is a very easy way to conceive of percentages, which makes use of a basic understanding of ratios. Essentially, students must be told that percentages are simply a special kind of proportion; one in which the denominator is always 100. The key to any lesson using ratios as a launching point, and percentages as the end point, is understanding cross-multiplication. An exercise taking this approach can really make use of virtually any objects to aid in visualization, but M&Ms are always good, because they give the students a tasty reward when the less on is complete. Tell the students to take 4 red M&Ms out of the wrapper and place them on their desk. Ask them, "How many of the 4 M&Ms on your desk are red?" The answer, which should be obvious to most students, is 4. Next, ask them to express this as a ratio, with the number of red M&Ms on top, and the number of total M&Ms on the bottom -- 4/4. Next, ask the students to take out one blue M&M and place it with the other four. Now ask, "How many of your 5 total M&Ms are red?" Then, once again, ask the students to express the number of red M&Ms to the number……

Hamlet How Do You React to Hamlet's

Hamlet How do you react to Hamlet's treatment of Ophelia in Act 3, Scene 1? What evidence suggests that he knows he is being watched by Claudius and Polonius? Hamlet shouts that there will be no more marriages, which is a direct threat to Claudius rather than to Ophelia. He also calls Ophelia false, and seems to believe that she has betrayed him, which only makes sense if he feels she is being used. While Hamlet's paranoia could be a product of his overwrought emotional state and hatred of Gertrude, the fact that he reacts so violently to her gentle rebuke suggests that he is angry at Ophelia for going along with what he sees as a trap, not just her romantic rejection. What does Hamlet think of the Claudius's reaction to "The murder of Gonzago"? Why does Claudius not react to the dumb-show before the play-with-in-a-play? Hamlet believes that the king's reaction is proof of his guilt. However, it could be that Claudius is more self-controlled, and does not react to the dumb-show because he does not wish to give himself away, and then he is simply is tired of seeing the Player King commit murder two times over, in……

Stress and the Body in Patients With Non-Healing Wounds

Nursing Stress and the Body in Patients with Non-Healing Wounds Walburn, J., Vedhara, K., Hankins, M., Rixon, L., & Weinman, J. (2009). Psychological stress and wound healing in humans: a systematic review and meta-analysis. Journal of Psychosomatic Research, 67(3), 253-271. This article is a review of existing research that has been done in relation to psychological stress and wound healing. Initially twenty-two papers were identified as meeting the inclusion criteria for a systematic review and a subsample of 11 were identified as being able to be included in a meta-analysis. The studies looked at the impact of stress on the healing of an assortment of wound types in dissimilar circumstances, including acute and chronic clinical wounds, experimentally produced punch biopsy and blister wounds, and small damage to the skin caused by tape stripping. Seventeen studies in the systematic review found that stress was associated with impaired healing. The conclusion drawn by the authors was that there needs to be research done towards investigating possible moderators of the relationship, intervening mechanisms supporting the association, as well as the demonstration of a causal link by the advance of experimental interventions in healthy people. The authors present the idea that cutaneous wound healing is a multifaceted process composed of interdependent and overlapping stages, including clot formation, inflammation, proliferation, and remodeling. The initial post injury phase is characterized by the formation of a fibrin clot followed by the inflammatory stage, usually within 1 -- 3 days after injury which is dominated by immune cells that destroy bacteria and debride the wound. These substances are crucial if normal tissue repair is to progress. It is believed that successful healing is dependent in part on a completely functioning immune system therefore making it susceptible to the myriad of factors which can damage immune performance. Since both acute and chronic psychological stress can modulate immune……

Contracts Scenario on June 15,

The two could have entered into an agreement whereby the buyer had a certain amount of time to change his or her mind, but this was not the case in the aforementioned offer. "Be mindful that you can take back or withdraw an offer at any time before the other side has agreed to the deal. This is called retraction (proving that you have withdrawn the offer before the other side accepted may present a problem). On the other hand, changing your mind after you have signed or agreed precludes retraction. Absent compelling reasons for not holding up to your end of the bargain, you will be a party to a contract." ("Contracts," 2004) As there is no proof of acceptance in this case of the initial offer, however, the buyer Bronson is in the clear and can keep his mower to the chagrin of Mason and Peters. Works Cited "Contracts." (2004) Retrived at November 23, 2004 at……
