Calculating the Pearson Product-Moment Correlation Coefficient The product-moment correlation coefficient allows for the calculation of two linearly dependent variables. In this case, the variables will be represented by x and y. The example to apply is a case of a pharmacy with an owner interested in knowing the time taken in the pharmacy (x) and money spent (y) by every tenth client in minutes and dollars, respectively. The assumption is that those who take a long time will spend more (positive correlation) and vice versa (Kenney & Keeping, 2011). To solve this puzzle, it is possible to compute the product-moment correlation coefficient denoted by r. The above case can be calculated as illustrated below. Step 1 Step 2: Eliminate all the incomplete pairs. In doing this, observations with known values of x and y are included, even if the values are zero as illustrated in figure 2 below. Step 3: Step three entails summarizing the resulting data into distinct values for computation by using the following signs. n: Summation of pairs of data Σ(x 2 ): Summation of x values squared Σx: Summation of the x values Σ(x*y): Summation of each value of x which is multiplied by the y value that corresponds to the x values Σy: Summation of the y values Σ(y 2 ): Summation of the y values squared The above x and y values give the following figures when computed. Step 4: Compute the ss xy , ss xx , and ss yy with the above values as summarized below. ss xy =Σxy-(ΣxΣy÷n)=283-(12*93/5)=59.8 ss xx =Σx 2 -(ΣxΣx÷n)=40-(12*12/5)=11.2 ss yy =Σy 2 -(ΣyΣy÷n)=2089-(93*93/5)=359.2 Step 5: The resulting values should then be inserted into the initial equation for the Pearson coefficient as illustrated below. r=ss xy /(ss xx *ss yy )**0.5=59.8/(11.2*359.2)**0.5=0.9428 Step 5: Interpreting the results Option 1: When the value is close to 1, it indicates that there is a strong and positive correlation (Howell, 2016). Option 2: When the value is very close to zero, it indicates no correlation. Option 3: When the value is close to -1, it indicates that there is a strong and negative correlation. In this case, since the value is 0.9428, which is very close to 1, there is a strong positive correlation between time and money spent in the pharmacy. Calculating Simple Linear Regression A simple linear regression explains the link between variables with the use of a straight line (Mugenda & Mugenda, 2013). For instance, consider data collected from a health center on different tests where each yield is associated with the temperature reaction as summarized in the figure below. The above data can be entered in Microsoft Excel and a simple scatter plot may be derived as indicated below. The variables of yield and temperature values are represented by yi and xi respectively. From the above scatter plot, there is no single line that can touch all
The analysis of David Pogue’s review of new model of Blackberry fails to provide a fair assessment because it focuses mainly on negative critique. In particular, the author criticizes the concept, introduction of clicking sounds for the touch screen board, and software design in general. Despite the dominance of negative comments, Pogue still manages to introduce some positive insights to the article. The favorable review has been dedicated to the analysis of touch screen effect, particularly to the click sounds, which seems to be an advantage of Blackberry Storm.

The financial plan is organized in a manner that allows successfully completing the project’s objectives;                                                                                                                                                                                      2. The budget represents the monthly costs, thus, can be easily adapted to the unplanned changes in the expenses, revenues, or customer demand;                        Financial Principles (adopted from Principles of financial management , n.d.)                                              3. The latter implies that the financial plan should be often reviewed and compared to the actual performance;                                                                                                                                                                                    4. The project seeks to operate within the predetermined budget and do not exceed it or leave certain financial and material resources unused without adequate reason;                                                                                                                            5.

This, in turn, would help to improve the quality of provided services by the doctors significantly and, thus, have a positive impact on the local community.
The existence of governments and countries with different systems of organization raises questions about how nations coexist. Moreover, other inquiries about economic and social stability inside the countries exist. These issues are addressed in the field of political science – a scientific approach to studying politics (Department of Political Science, 2022). The following critique presents an introduction to political science, its scope and methods, and the discipline’s role in science and people’s view of the world. As noted above, political science is concerned with every aspect of governance. For example, a political scientist may investigate various political theories, the concept of power on a national and international scale, or study the interaction between several states (Gooding and Hoekstra, 2020). Political science is a part of social sciences that views human relationships from various angles (Keping, 2018). It differs from history because it applies the scientific method to the existing information instead of simply restating facts (Maddocks, 2020). Similarly, it presents a view separate from political philosophy, focusing on theoretical discussions removed from the current political sphere (Bunte, 2019). Nevertheless, the fields draw upon each other, making them related. Moreover, as a social science, the study of politics applies various methods from related disciplines, including law, sociology, economics, anthropology, and more. According to research, one can distinguish three major subfields of political science. The first segment of the discipline is political theory, a subfield focused on the foundations of political establishments (Keping, 2018). Due to the theoretical nature of research, the subfield’s main research topics are related to human nature and its impact on the creation and development of political institutions (Longo and Zacka, 2019). The approaches in political theory range from feminist theory to country-focused thought schools (Ackerly and True, 2019). Through different views enriched by other disciplines, political theory presents an analysis of politics through the lens of different communities. Second, comparative politics is another major field of political science. In this subfield, the existence of various political systems is the foundation for research. Scientists select and compare different political structures to assess their progress and understand the values of each community in relation to one another. For instance, such topics as the countries’ approach to equality, economic security, and freedom may be a part of a comparative political study (Maddocks, 2020). Another aim of comparative politics is to analyze the creation of political institutions in different societies, comparing factors that may influence
The war produced a profound impact on America’s attitude to Asians in terms of racial perceptions and actual treatment of all Asian minority groups. However, it did not affect all Asians equally. In general, most Asian Americans benefited from war as the Filipino, the Chinese, and Indians were wartime allies of the United States. Since the government was afraid of strategic losses to their enemies, they decided to combat racial ideologies at home and abroad. A new, positive attitude to representatives of these nations was mainly explained by their heroic participation in battles and their willingness to be enlisted to fight against the Japanese (although they were actually promised the citizenship). Nevertheless, even this improvement in perception did not give any considerable advantages. On the contrary, the Japanese suffered greatly in the aftermath of war. Japan was an enemy and therefore Japanese Americans were perceived as “enemy aliens” and singled out for “group punishment” by Executive Order 9066. This was majorly due to the attack at Pearl Harbor, after which all Japanese American communities started to be viewed as sources of potential threats. The fear of “Yellow Peril” achieved its peak, which led to an unprecedented violation of constitutional rights as Japanese immigrants were forced to live in detention camps. Furthermore, the government never made any efforts to help them restore their position in the society. Another great impact was produced by the Cold War with Russians as the nation realized the hazard of the so-called “domino effect”, which implied that the neighboring countries could turn to communism following Russia’s example. This was exactly what happened to the Korean peninsula and China. Chinese immigrants were prosecuted for the fear of communism spreading in the country. Yet, the United States was still forced to change its racially-biased immigration policy since it evidently exerted negative influence on its relations with Asian countries. The Asian American Movement, which emerged in the late 1960s and lasted until the middle of 1970s, had a lot of underlying historical, ideological
Introduction Woody Allen sued Amazon on February 7, 2019, for violating contract laws. The company had made a four-movie deal with Allen, forcing him to accuse the firm in Federal Court after canceling the agreement to make four films (Vidgor, 2019). Consequently, the plaintiff is Allen, and the defendant is Amazon. The issue is that Amazon claimed that the plaintiff was being accused of sexual assault. Hence, Amazon filed an appeal to justify its decision as it had an adverse impact on the firm’s financial security. Fact Analysis The law used by the court was not disclosed since the issue was settled between the two parties. Therefore, one can argue that parties can come to an agreement and resolve their disputes. The reasons given by the court were that the defendant and the plaintiff settled their issues in private and the appellant withdrew the case. In this case, individuals can dispute that renewal of contract or compensation might be the reasons that led to the case’s settlement. Many appellants have withdrawn their accusations after agreeing with the appellee. Similarly, various factors could have led to the agreement between Allen and Amazon. Conclusion and Opinion To conclude, courts have guaranteed that plaintiffs may withdraw their cases due to different reasons. Moreover, some disputes are settled without involving the court, leading to the plaintiff’s request to cancel the case. In my opinion, Allen was right since the company had contacted him, being aware of his sexual assault accusations. Correspondingly, the court should have considered his argument since breaching the contract was exercised. I agree with the court’s decision to let Allen withdraw the case since the parties had resolved their matter. A social impact could be involved, whereby many people learn about contract law and the importance of seeking justice when violated. Contract breaching is also common in America, and the case can be used to create awareness of its dangers. Reference Vidgor, N. (2019). Woody Allen and Amazon settle breach of contract lawsuit.

Introduction Owners of intellectual property have a duty to ensure that the commercialization of their property does not, in any way, conflict with the law. In the Information Technology sector, programmers should ensure that the programs they develop are in agreement with the provisions of the law and that they do not develop programs that will be used in illegal activities like hacking. Similarly, providers of internet services should ensure that the materials that they post on their websites are in agreement with the law. For instance, owners and operators of blogs, websites and social networks are partly liable for defamatory statements posted on their sites depending on their level of involvement in the creation of the defamatory information. This paper analyses the interconnection between the legal liability of owners of intellectual property and the use of the intellectual property by looking into internet service provision and defamation on the internet. Cyberlibel With the increased popularity of internet blogs and social networks, the rate of defamation on the internet has also increased. Defamation generally refers to false and negative representation of another person’s character leading to a bad reputation. It takes two main forms: slander and libel. Slander is in form of spoken language while libel is written. The most common form of defamation on the internet is libel. This is because of the written evidence that blogs, websites and social networks provide to their users. One of the factors that have facilitated the increase of cyberlibel cases is the ever-increasing popularity in the use of computers and the internet. The internet now gives services spanning virtually all realms of life. People use the internet to shop, to find news, to run business transactions, for entertainment etc. This implies that the internet is being accessed by a great number of people with various levels of awareness of the law. The effect of this is that some ignorant people may use the internet illegally by posting defamatory materials on the internet. Such information will be accessed by a lot of people and thus it will have adverse effects. This behavior should be strictly discouraged to ensure that technology is used to achieve the goals it is intended to achieve. In most cyberlibel cases, the defamed person has information on the sites that he/she can use to prove the offence. Once the person proves that he/she has been defamed, he/she is normally entitled to damages with liberality. Owners of Blogs Owners and operators of social networks and blogs h
Introduction A psycho-educational group therapy is one of the psychological interventions instituted for people having certain degrees of psychological crisis or people who are at a risk of the same in the future. It is commonly instituted for people undergoing tuition where their instructors feel that they are handling a psychosomatic predicament. According to Forsyth, one of the functions of a psycho-educational group therapy is to make the participants aware of their condition, teach them about it, and prevent the symptoms of the condition from recurring in the individual again (2014, p. 34). The main theory applied is that, by meeting people with similar conditions, the participants are able to share and enlighten themselves and at the same time alleviate the feeling of being alone (Forsyth, 2014, p. 34). One condition that is often treated and prevented with this form of therapy is the occurrence of postpartum depression in new teenage mothers because of the new life changes. The arguments made in the paper are based on a discussion I held with Rachel Caster who is the leader of Teen Mothers Forum Organization (TMFO). The discussion we held as tabled in the paper describes a possible psycho-educational group for the new teen mothers that can offer support and education to help them with their new life changes and to help them identify warning signs for possible postpartum depression. Targeted audience and choice of the audience As stated above, the targeted audiences for the psycho-educational group therapy are new teenage mothers who were selected based on a number of reasons, with the main one being the high prevalence of post-partum depression among this age group of mothers. According to Devine, Bove, and Olson, “The transition to motherhood is a pivotal time of psychological, developmental, and biological change in a mother’s life” (2000, p. 579). Caster pointed out how new mothers are often faced with a number of psychological stressors such as physical exhaustion, role restriction, financial problems, social isolation, and depressive symptoms as well as confusion (Reis, 1989, p.146: Reis, 1988, p. 541). According to her, mothers’ experience with these stressors decreases with the number of pregnancies and primigravidas with no prior experience process of the highest risk of the post-partum depression and associated stressors. Based on their age and experience, teenage mothers therefore are at the greatest risk of developing the postpartum depression as compared to other mothers of higher ages. True to this observation, the number of teenage mothers with post-partum depression is high. The apparent large number of teenage pregnancies all over the world has not assisted this situation. Teenage mothers were therefore chosen on this basis. Caster also recognized psycho-educational group therapy as one of the therapies that have the potential to prevent the post-partum depression associated with the new teenage mothers or any other category of mot
Kang & Balitanas (2009) define IKE as a spontaneous key management protocol created by the combination of several other different key management protocols, and serves as the default key generator for IPsec, a shortened form for Internet Protocol Security. It creates, encrypts and authenticates all secret keys generated between two computers on a network. It further helps to determine and configure security associations (SAs) necessary for a secure communication, and specifies the protocol format, cryptographic and hashing algorithms, used between the two computers. Kyburz (2010) notes that “the two peers on either side of the SA usually store the cryptographic keys, encryption algorithms, authentication schemes, and all integrity protection mechanisms supported by that connection in the SA”. All this information is exchanged between the two computers using digital signatures and message authentication codes (MACs). Easttom (2006) defines a digital signature as any accessional data included in a message, containing an e-mail addendum, used to corroborate the authenticity of the sender of the message. They are anchored on private and public encryption keys and use digital certificates (DCs), provided by Certificate Authorities (CAs). CAs use information supplied to them to generate the digital certificate, with an encrypted private key for the requester. Kyburz (2010) asserts that, the receiver of a signature will apply the signer’s public key in the decryption and verification of the signature. Where the public key is unknown, it can be requested through a certificate request (CR). According to Mason (2002), there are two distinct phases in an IKE protocol. Phase one includes the fabrication of an authenticated and secure channel, amid the two computers, that is called the IKE Security Association, by the Diffie-Hellman key correspondence being performed. In the second phase, IKE negotiates the IPsec security associations and yields the preferred keying material. Kyburz (2010) notes that, “the generated key material is transferred to the IPsec, which tracks and supervises the security of all the subsequent communication channels”. The mechanisms that IKE uses to encrypt and authenticate all forms of communications between the initiator and responder are either symmetric or asymmetric. In an asymmetric key encryption system, one key referred to as the public key, is availed to everybody, and is used to encrypt a message, but only the recipient has got the private key to decrypt the message/data. On the other hand, a symmetric data encryption, also referred to as conventional data encryption, uses a common key to encrypt and decrypt data. The types of conventional encryption methods fall under the Extensible Authentication Protocols (EAPs) and include; Data Encryption Standard (DES), Advanced Encryption Standard (AES), International Data Encryption Standard (IDEA) among others. These are discussed b
