Over-Population and Earth Processes essays

Over-Population and Earth Processes essays The Earth is facing two major issues with regards to its carrying capacity and over-population. Society continues to populate the Earth while the average life expectancy continues to rise. The Earth can only support a set amount of humans before its resources are used up. As well as the Earths resources becoming exhausted, there is also the issue of the high human population polluting the water to the point that some water reserves are not safe for consumption. In 1998 the world population reached 5.9 billion people according to the United States Census Bureau.1 These population figures signify that the world population has at least doubled since 1950, at which time the world population was only 2.6 billion people.1 The Earths population still continues to rise and has already reached the 6 billion people mark. If these population figures remain constant, the Earth will be well over its carrying capacity. With the continuing rise in world population comes the issue of the Earths resources becoming exhausted. An example of these exhausting of resources is oil. Society is already facing the issue of the Earths oil reserves being spent. The economic law of demand states The principle that, other things equal, an increase in a products price will reduce the quantity of it demanded; and conversely for a decrease in price.2 Because the price of oil has increased drastically over the last three years, the amount of oil that society uses has somewhat decreased because consumers are identifying the issue of oil consumption and are now buying more fuel-efficient vehicles.3 According to the economic law of demand, as more consumers switch to more fuel-efficient vehicles, the price of oil will come down again because the demand for oil will diminish and our oil reserves will remain stable. However, our oil reserves will only remain stable if more of society changes their lifestyles to accom m...

How to Conjugate Influencer (to Influence) in French

How to Conjugate Influencer (to Influence) in French As you might suspect, the French verb  influencer  means to influence. Yet, when you want to say influenced in the past tense or influencing in the present tense, youll need to know how to conjugate the verb. A quick lesson will introduce you to the most important conjugations youll need. The Basic Conjugations of  Influencer French verb conjugations are not the easiest lessons and some are more challenging than others. Influencer is a spelling change verb and that may sound scary at first, but its not bad and theres a good reason for it. The spelling change affects the  c  at the end of the verb stem  influenc-. Typically, when that letter is followed by the vowels  a  or  o, the sound is hard as in cat. To retain the soft  c  sound in the conjugations with endings that begin with these vowels, the  c  changes to a  Ãƒ §. Other than that minor difference in some verb forms,  influencer  is conjugated like a  regular -er  verb. Using the chart, you can study these conjugations by pairing the subject pronoun with the present, future, and imperfect past tenses. As an example,  jinfluence  means I am influencing and  nous influencions  means we influenced. Present Future Imperfect j' influence influencerai influenà §ais tu influences influenceras influenà §ais il influence influencera influenà §ait nous influenà §ons influencerons influencions vous influencez influencerez influenciez ils influencent influenceront influenà §aient The Present Participle of  Influencer Due to the -ant  ending used to form the  present participle  of  influencer, the spelling change is required here as well. That gives us the word  influenà §ant. Influencer  in the Compound Past Tense Passà © composà ©Ã‚  is another way to say influenced in French. This compound past tense requires the  past participle  influencà ©Ã‚  and an auxiliary verb. To form this, conjugate  avoir  into the present tense for the subject, then add  influencà ©. This leaves us with phrases such as  jai influencà ©Ã‚  (I influenced) and  nous avons influencà ©Ã‚  (we influenced). More Simple Conjugations of  Influencer Among the other simple conjugations, you may need for  influencer  are  the subjunctive  and  the conditional. Both give the act of influencing some uncertainty, though the conditional says it will only happen under certain conditions. If you read or write much French, you will likely encounter  the passà © simple  and  the imperfect subjunctive. These are literary tenses and used frequently in formal French writing. Subjunctive Conditional Passà © Simple Imperfect Subjunctive j' influence influencerais influenà §ai influenà §asse tu influences influencerais influenà §as influenà §asses il influence influencerait influenà §a influenà §Ãƒ ¢t nous influencions influencerions influenà §Ãƒ ¢mes influenà §assions vous influenciez influenceriez influenà §Ãƒ ¢tes influenà §assiez ils influencent influenceraient influencà ¨rent influenà §assent It is possible that you will find some uses for  influencer  in  the French imperative.  When you do use it, all formality is dropped and you can skip the subject pronoun. Imperative (tu) influence (nous) influenà §ons (vous) influencez

Discuss the key features of effective corporate decision making and Essay - 1

Discuss the key features of effective corporate decision making and access how well these are being applied in an organisation y - Essay Example Contextually, it can be stated that effective decision-making is a systematic process through which business managers select alternative sources and implement it in an efficient manner in order to attain their various business purposes and objectives by a significant level (Harvey, 2007). Police forces of the United Kingdom (UK) can be recognised according to the set of ranks under which several types of departments are operated in an effective manner. The UK police comprise British police force and City of London Police where various sorts of job responsibilities are distributed according to the departmental requirement. In general, the core mission of entire police forces is to prevent crime and protect community people against the conduct of any uncertain criminal assaults. It has been apparently observed that the UK police forces perform their job responsibilities according to the community requirements (Association of Chief Police Officers, 2011). In this paper the key features of an effective corporate decision-making process will be taken into concern. Moreover, the application of this process relating to the UK police force has also being discussed. ... n to determine the workplace objectives of the police force of the UK, it has been viewed that the core workplace objective of the UK police is to maintain equality that helps them to create and make essential decisions in order to improve their operational performance. In this regard, the Metropolitan Police Service (MPS) of the UK formulates certain equality objectives in order to evaluate diversity as well as equality amid the entire police forces. Through this aspect, departmental heads understand the behavioural attitudes of entire police force and also comprehend their acceptance capability towards fulfilling their different job responsibilities (Assistant of Chief Police Officer, 2011; Mayor’s Office for Policing and Crime, 2013). There are several equality objectives that are implemented within the workplace of the UK police force through which they can improve their operational performance. These equality objectives include delivering fair, responsive as well as favou rable services to every community member and engaging all the community members in listening as well as responding their respective problems. Additionally, the other objectives comprise developing an effective workforce in order to become more responsible towards the community members and preserving equality standards while performing and delivering services to the community members (Assistant of Chief Police Officer, 2011; Mayor’s Office for Policing and Crime, 2013). After acquiring a brief idea about the workplace objectives of the UK police force, it has been viewed that at present, UK police department face several types of workplace issues that impose considerable impact upon their operational activities. Since the past few years, ‘Public disorder’ is one of the challenging issues

Leadership - Essay Example The corporate executives and business owners of UAE are now aware about the challenges and opportunities that are linked with the cultural diversity of the work force. According to Taylor Cox Jr. â€Å"an increase in globalization of business and combination of multi cultural workforce can be a key factor in overall success of the business (Daenzer, 2009). The benefits of this diversity includes a better decision making, high innovation and creativity, more efficiency and success in marketing to minority ethnic communities and foreign markets, and a wide spread distribution of economic opportunity (Muna, 2011). But this multicultural work force has certain disadvantages also which includes increase in costs through increase in turnover rates, communication breakdowns and interpersonal conflict. In order to bring out efficiency amongst the diversity in culture of workforce the leaders should be aware about how to manage and create an effective multicultural workforce (Connerley, 2005 ). Thus a research in this field is important to analyze the trends of the multicultural workforce in UAE and the leadership style needed to manage this cultural diversity. UAE has more than 200 nationalities working together where implementation of multicultural leadership to bring a change in working environment and even to handle multicultural customers (Edewor, 2007). This research will be useful for all the leaders in organization on how to manage this multicultural workforce. The main audience of the research study will be the small business owners, and also leaders of bigger enterprises, to develop better leadership tools to handle the work force of diverse culture and convert the loop holes of multi cultural workforce into advantage for the business (Livermore, 2010). A multicultural workforce contains people coming from different cultural backgrounds and will have different way of dealing with a problem in the

A Spatial Median Filter for Noise Removal in Digital Images Essay Example for Free

A Spatial Median Filter for Noise Removal in Digital Images Essay With each snap of a digital photograph, a signal is transmitted from photon sensor to a memory chip embedded inside a camera. Transmission technology is prone to a degree of error, and noise is added to each photograph. Signi? cant work has been done in both hardware and software to improve the signal-to-noise ratio in digital photography. In software, a smoothing ? lter is used to remove noise from an image. Each pixel is represented by three scalar values representing the red, green, and blue chromatic intensities. At each pixel studied, a smoothing ? lter takes into account the surrounding pixels to derive a more accurate version of this pixel. By taking neighboring pixels into consideration, extreme â€Å"noisy† pixels can be replaced. However, outlier pixels may represent uncorrupted ? ne details, which may be lost due to the smoothing process. This paper examines four common smoothing algorithms and introduces a new smoothing algorithm. These algorithms can be applied to one-dimensional as well as two-dimensional signals. Figure 1. Examples of common ? ltering approaches. (a) Original Image (b) Mean Filtering (c) Median Filtering (d) Root Signal of Median Filtering (e) Component wise Median Filtering (f) Vector Median Filtering. The simplest of these algorithms is the Mean Filter as de? ned in (1). The Mean Filter is a linear ? lter which uses a mask over each pixel in the signal. Each of the components of the pixels which fall under the mask are averaged together to form a single pixel. This new pixel is then used to replace the pixel in the signal studied. The Mean Filter is poor at maintaining edges within the image. 1 N ? xi N i=1 MEANFILT ER(x1 , , xN ) = (1) The use of the median in signal processing was ? rst introduced by J. W. Tukey [1]. When ? ltering using the Simple Median Filter, an original pixel and the resulting ? ltered pixel of the sample studied are sometimes the same pixel. A pixel that does not change due to ? ltering is known as the root of the mask. It can be shown that after suf? cient iterations of median ? ltering, every signal converges to a root signal [2]. The Component Median Filter, de? ned in (3), also relies on the statistical median concept. In the Simple Median Filter, each point in the signal is converted to a single magnitude. In the Component Median Filter each scalar component is treated independently. A ? lter mask is placed over a point in the signal. For each component of each point under the mask, a single median component is determined. These components are then combined to form a new point, which is then used to represent the point in the signal studied. When working with color images, however, this ? lter regularly outperforms the Simple Median Filter. When noise affects a point in a grayscale image, the result is called â€Å"salt and pepper† noise. In color images, this property of â€Å"salt and pepper† noise is typical of noise models where only one scalar value of a point is affected.

Before I explain and talk about why a ball goes farther when hit with an aluminum bat, I would like to present and explain some vocabulary concept and words. A collision, transfers momentum or kinetic energy from one object to another object. There are two types of collisions, elastic collision and inelastic collision. An elastic collision is a collision that occurs when two objects bounce apart when they collide; the total kinetic energy in the system is the same before and after the collision. For example, elastic collision occurs when equally massive balls move in the same direction; in this case momentum is transferred from one ball to another ball. And an inelastic collision is a collision that occurs when two objects collide and do not bounce away from each other; the collision changes the total kinetic energy in a closed system. For example, inelastic collision occurs when two cars crash and join themselves into one; the objects stick together after colliding. In inelastic c ollision all that happened is the loss of some kinetic energy, objects don not necessarily need to stick together in an inelastic collision. Whether a collision is an elastic collision or inelastic collision momentum would always be the same before and/or after the collision as long as you have a close system. According to Asif Shakur, Chair of Physics and Engineering at Salisbury State University, explains, â€Å"Aluminum is a hard material. It doesn't have a lot of "give." In other words, aluminum is highly elastic. Therefore, very little of the ball's initial kinetic energy (the energy associated with motion) is used up in permanently deforming the aluminum. Indeed, the aluminum springs back quickly and the ball retains much of its initial energy. In co... ...reased the animosity between the two players† (Russell). The point of all of this is that Piazza’s bat broke; professional players typically go through a lot of bats during a baseball season. In conclusion, there are a various numbers of reasons why a ball go farther when hit with an aluminum bat; such as, aluminum bat can be swung faster, aluminum bats have the trampoline effect, aluminum bats have winder sweet spots, and aluminum bats don’t break. A ball goes farther when hit with aluminum bat because of the fact that the bat is very lightweight and have a large 'sweet spot' in which to hit the ball. In order to have a ball with a high speed, in other words, lots of kinetic energy, the collision has to an elastic collision. Aluminum bats can be swung faster because the barrel of an aluminum bat is empty; the distribution of mass along the length of a metal bat.

Analysis of Alice in Wonderland

Adulthood in Wonderland A journey begins with a single step. It may be an African safari, a rocket to the moon, or even a voyage around the world. Whatever the adventure, it must start somewhere. It could begin with a leap of faith, a glint of hope, or just a flicker of curiosity. In Alice’s Adventures in Wonderland, by Lewis Carroll, curiosity is what brings Alice, a young British girl, to the start of her incredible, yet puzzling expedition. Her journey through Wonderland is strange, but through her experiences, Alice grows up along the way.Through his use of symbolism, Lewis Carroll displays that it is a struggle for a child to make the transition into adult life. The character of the White Rabbit is the first symbol used to present the difficulty of becoming an adult. The rabbit is very official and is a symbol of an adult itself. For example, he is exceptionally busy and always running late, just like an average adult. He gives the King of Hearts, the ruler of Wonderland, advice although he is beneath him, which demonstrates that he is also wise like an adult.When Alice first sees the rabbit she is filled with curiosity as she â€Å"had never before seen a rabbit with a waistcoat- pocket, or a watch to take out of it† (2). Without thinking, Alice follows the rabbit into the rabbit- hole and falls â€Å"down, down, down† into Wonderland (4). Since the White Rabbit symbolizes an adult, it is as if Alice is following him into adulthood. The rabbit travels throughout Wonderland, and wherever he goes, so does Alice. For example, the White Rabbit travels to the Queen of Hearts’s garden, and eventually Alice arrives also.The White Rabbit acts as a guide for Alice as she goes on her journey. As the White Rabbit symbolizes adulthood, he leads Alice through the process of maturing. Even though Alice does not confront any struggle with the White Rabbit, her following of him brings her to the challenges she endures later on. The White Rabbi t’s symbolism carries Alice through the puzzling task of growing up. Another use of symbolism that represents maturing occurs when Alice encounters the Caterpillar. Alice discovers the Caterpillar when she stumbles upon his mushroom.The Caterpillar addresses her and asks, â€Å"Who are you? † (45). Alice cannot answer the Caterpillar as she is unable to explain herself and does not know who she is at the moment. She tells the Caterpillar, â€Å"I know who I was when I got up this morning, but I think I must have been changed several times since then† (45). Alice’s words display that her identity has been altered and that she is having a difficult time trying to keep up with these changes. A child going through puberty encounters similar changes also. Children lose a sense of their innocence and discover themselves as they mature.As demonstrated by the scene with the Caterpillar, Alice’s loss of identity is a symbol of a child’s loss of onese lf when growing up. Alice’s episode with the Caterpillar also symbolizes another point of becoming older. The Caterpillar demands Alice to recite the poem â€Å"You are old, Father William. † Alice does as she’s told, but as she is reciting the poem, she becomes confused and mixes up the words. Because Alice struggles with this, it symbolizes a child having a hard time adjusting to the demands of adulthood.The Caterpillar’s request represents a demand that adults must face; while Alice’s mixing up of the poem’s words signify a child failing at meeting the requirements of that demand. The symbolism found in Alice’s encounter with the Caterpillar demonstrates the effort of transitioning into adulthood. Finally, Alice’s changes in size illustrate the difficulty of maturing. Throughout the book, Alice becomes a variety of different heights. One minute, she is three inches tall and the next, she is â€Å"opening out like the larges t telescope there ever was! (11). Alice’s size changes are sudden and random. For example, Alice drinks a liquid from a small bottle and rapidly shrinks to ten inches high. Alice does not expect this and finds it â€Å"a curious feeling! † (8). Since Alice’s changes are unexpected and uncontrollable, they symbolize what a child experiences through puberty. Children are unaccustomed to the changes in their bodies and struggle to adjust to their new selves. Alice’s growing and shrinking proves to be a challenge when her identity is mistaken for another.In one episode where Alice grows to enormous heights, she comes in contact with a pigeon. The pigeon mistakes her for a serpent, because of her long neck. Alice tries to convince the bird that she is just a young girl, but the pigeon does not believe her. Alice is frustrated by this and does not understand why the bird won’t take her word, even though she is telling the truth. This encounter, caused by Alice’s ridiculous size, again represents a child adjusting to their changed body while going through puberty.However, this example also illustrates that as children mature, adults immediately believe they have new identities. Adults view children differently, even when those children haven’t adjusted to their selves yet. The height changes that Alice endures create an image of the struggles of puberty. Through his work, Lewis Carroll demonstrates the difficulty of growing up by the use of symbolism. Maturity is a challenging journey, but one that must be taken. No matter when this adventure occurs, it begins with an individual step and remains the rest of a lifetime.

Kant

IMMANUEL KANT’S THEORY Immanuel Kant (1724-1804) discussed many ethical systems and reasonings. Some were based on a belief that the reason is the final authority for morality. In Kant's eyes, reason is directly correlated with morals and ideals. Actions of any sort, he believed, must be undertaken from a sense of duty dictated by reason, and no action performed for appropriateness or solely in obedience to law or custom can be regarded as moral. A moral act is an act done for the â€Å"right† reasons. Kant would argue that to make a promise for the wrong reason is not moral you might as well not make the promise.You must follow a certain code in order to find truth behind your actions. Kant believed that you should treat everyone with value, dignity, and respect. Our reasoning ability will always allow us to know what our duty is. Kant described two types of common commands given by reason: the hypothetical imperative, which dictates a given course of action to reach a specific end; and the categorical imperative, which dictates a course of action that must be followed because of its rightness and necessity.The categorical imperative is the basis of morality and was stated by Kant in these words: â€Å"Act as if the maxim of your action were to become through your will and general natural law. † Therefore, before proceeding to act, we must decide what rule we need to follow if we were to act, whether we are willing for that rule to be followed by everyone all over. Kant believes that moral rules have no exceptions. It is wrong to kill in all situations, even those of self-defense. This belief comes from the Universal Law theory.Since we would never want murder to become a universal law, then it has to be not moral at all. Kant believes killing could never be universal, therefore it is wrong in each and every situation. There are never any extenuating circumstances, such as self-defense. I believe Kant is right in making certain moral and e thical codes exempt from being a universal law because there shouldn't be different rules for different laws. The rules and laws should apply to every situation. An act is either wrong or right, based on his universality law.For example, giving money to a homeless person just to get him/her to leave you alone would be judged not moral by Kant because it was done for the wrong reason. With Kants belief in mind; if the consequence of immoral behavior were dealt with in a legal structure, people would be prosecuted for â€Å"EVERYTHING† since there are no extenuating circumstances. Kant's categorical imperative is a tri-dynamic statement of philosophical thought:(1) â€Å"So act that the maxim of you could always hold at the same time as a principle establishing universal law. (2) â€Å"Act so as to treat humanity, whether in your own person in that of another, always as an end and never as a means only. ‘(3) â€Å"Act according to the maxims if a universally legislativ e member of a merely potential kingdom of ends. † In other words, Kant argues that particular action requires conscious thought of the rule governing the action. Whether if everyone should follow that rule, and if the rule is acceptable for universal action, it should be adopted. If the rule is unacceptable, then it should be rejected.In order to understand whether or not an action follows Kant's â€Å"categorical imperative,† we must prescribe those norms that we wish to be universal laws. We must make the judgment on whether or not universal ethics is possible. I believe that a bit of universality exists throughout the world; don't kill your neighbor, be kind to others, do not steal, etc. yet, individual perception of the world by people prevents the possibility of an all-encompassing universal code of ethics. I believe along with Kant that we should develop a friendship and code to help our fellow man.We all have a duty to treat others the way we want to be treated. The one thing I disagree with is that we should not be punished for doing good deeds to those even though we might find ourselves backed into a corner when dealing with these individual problems. Overall dealing with Kant's theory everyone should be truthful and abide by the universal code. We should follow his theory in treating everyone with value, dignity, and respect. Even though everyone should help others, I believe in some situations people have to be persuaded to help even though this goes against Kant's beliefs.

Annotations in Reading, Research, and Linguistics

Annotations in Reading, Research, and Linguistics An annotation is a  note, comment, or  concise statement of the key ideas in a text or a portion of a text and is commonly used in reading instruction and in research. In corpus linguistics, an annotation is a coded note or comment that identifies specific linguistic features of a word or sentence. One of the most common uses of annotations is in essay composition, wherein a student might annotate a larger work he or she is referencing, pulling and compiling a list of quotes to form an argument. Long-form essays and term papers, as a result, often come with an annotated bibliography, which includes a list of references as well as brief summaries of the sources. There are many ways to annotate a given text, identifying key components of the material by underlining, writing in the margins, listing cause-effect relationships, and noting confusing ideas with question marks beside the statement in the text. Identifying Key Components of a Text When conducting research, the process of annotation is almost essential to retaining the knowledge necessary to understand a texts key points and features and can be achieved through a number of means. Jodi Patrick Holschuh  and Lori Price Aultman  describe a students goal for annotating text in Comprehension Development, wherein the students are responsible for pulling out not only the main points of the text but also the other key information (e.g., examples and details) that they will need to rehearse for exams. Holschuh and Aultman go on to describe the many ways a student may isolate key information from a given text, including writing brief summaries in the students own words, listing out characteristics and cause-and-effect relations in the text, putting key information in graphics and charts, marking possible test questions, and underlining keywords or phrases or putting a question mark next to confusing concepts. REAP: A Whole-Language Strategy According to  Eanet Manzos 1976 Read-Encode-Annotate-Ponder strategy for teaching students language and reading comprehension, annotation is a vital part of a students ability to understand any given text comprehensively. The process involves the following four steps: Read to discern the intent of the text or the writers message; Encode the message into a form of self-expression, or write it out in students own words; Analyze by writing this concept in a note; and Ponder or reflect on the note, either through introspection or discussing with peers. Anthony V. Manzo and Ula Casale Manzo describe the notion in Content Area Reading: A Heuristic Approach as among the earliest strategies developed to stress the use of writing as a means of improving thinking and reading, wherein these annotations serve as alternative perspectives from which to consider and evaluate information and ideas.

Molarity of Ions Example Problem

Molarity of Ions Example Problem This example problem demonstrates how to calculate the molarity of ions in an aqueous solution. Molarity is a concentration in terms of moles per liter of solution. Because an ionic compound dissociates into its components cations and anions in solution, the key to the problem is identifying how many moles of ions are produced during dissolution. Molar Concentration of Ions Problem A solution is prepared by dissolving 9.82 grams of copper chloride (CuCl2) in enough water to make 600 milliliters of solution. What is the molarity of the Cl  ions in the solution?Solution To find the molarity of the ions, we must first find the molarity of the solute and the ion to solute ratio.Step 1:  Find the molarity of the solute. From the periodic table: Atomic mass of Cu 63.55Atomic mass of Cl 35.45Atomic mass of CuCl2 1(63.55) 2(35.45)Atomic mass of CuCl2 63.55 70.9Atomic mass of CuCl2 134.45 g/molNumber of moles of CuCl2 9.82 g x 1 mol/134.45 gNumber of moles of CuCl2 0.07 molMsolute Number of moles of CuCl2/VolumeMsolute 0.07 mol/(600 mL x 1 L/1000 mL)Msolute 0.07 mol/0.600 LMsolute 0.12 mol/LStep 2:  Find the ion to solute ratio. CuCl2 dissociates by the reaction CuCl2 → Cu2 2Cl- Ion/solute Number of moles of Cl-/number of moles of CuCl2Ion/solute 2 moles of Cl-/1 mole CuCl2Step 3:  Find the  ion molarity. M of Cl- M of CuCl2 x ion/soluteM of Cl- 0.12 moles CuCl2/L x 2 moles of Cl-/1 mole CuCl2M of Cl- 0.24 moles of Cl-/LM of Cl- 0.24 MAnswer The molarity of the Cl  ions in the solution is 0.24 M. A Note About Solubility While this calculation is straightforward when an ionic compound completely dissolves in solution, its a tiny bit trickier when a substance is only partially soluble. Basically, you set up the problem the same way, but then multiply the answer time the fraction that dissolves.

Econometrics Asignmnet using E-VIEWS SOFTWARE Essay

Econometrics Asignmnet using E-VIEWS SOFTWARE - Essay Example The company can estimate the sales to be using a regression model. The sales depend on the variables mentioned such as the USA nominal GDP, USA unemployment rate and the PMI index. The report provides a correlation matrix and regression model with the data on the sales being regressed and the output analysed. The correlation matrix shows that the variable for sales is significantly correlated with the USA GDP nominal with a positive Pearson coefficient of .957 (which shows a very strong positive correlation). The other two variables are also correlated with the dependent variable (with PMI index being negatively correlated with the dependent variable while USA unemployment rate having a positive correlation) they are however not significant at 5% significance level. The results from the regression model show that the explanatory variables have a lot of impact on the dependent variable (Sales). The study established that approximately 95.91% of variation in the dependent variable (sal es) is explained by the three explanatory variables (USA nominal GDP, USA unemployment rate and the PMI index) in the model. According to Creswell (2003), regression analysis is a statistical tool that is usually utilized by many researchers to investigate the relationship that exists if any between two or more variables. The aim of the investigation is to find a causal effect relationship. Using the data, the researcher can assess the statistical significance of the relationships that have been estimated.
