NBA vs. Owners - Essay Example For instance, in 2009 he paid $2.73 in fines to the federal government to settle claims that were placed on him regarding discrimination towards the African Americans and Latinos. Donald Sterling has also been sued in the past by his own 22-year manger on claims of harassment, discrimination, as well as wrongful termination. This case becomes a moral issue because the recording that Donald Sterling has been accused of was released to the press illegally and his conversation was recorded without his consent. This has led to Sterling claiming that his rights were violated. The image conscious NBA has several options that can be taken against the billionaire who has since maintained that he is not racist. This issue becomes more confusing because Donald Sterling has been involved in initiatives to support the minority groups.

For instance, helping the minorities and having a girlf riend from a minority group would be effective in showing that he is not racist and in improving his own image. Although the NBA has a clear constitution, several changes should be incorporated in it to ensure that firm actions are taken against individuals who make racist remarks. Due to the evil that is involved in racism, NBA should punish such individuals as Donald Sterling accordingly to ensure that such instances do not occur again in the future and to ensure equality in the American society. Preventing a re-occurrence of the same in the league, NBA should monitor the behavior of the team owners, create an environment that advocates for equality, react immediately to racist behaviors, and enforce racism cases regarding the league in the U.S constitution.

Waste Management (Firm Analysis) - Essay Example nvironment protection and regarded as an interface between the production, distribution and consumption of goods on the one hand, and soil, groundwater, air and climate on the other. Hence, it is an essential collaborator in the perspective of sustainable development. In the current scenario, industrialized nations are busy enhancing their regulatory frameworks and waste management infrastructure. As it is, the industry deals with extensively rising environmental and legal standards, best practices and the need for greater efficiency, quality management and occupational health aspects. Apparently, with the diversity and intricacy of products and accordingly of wastes, byproducts, and residues, there is no single solution to the waste treatment demands of today. A suitable combination of technologies is necessary in order to meet and respond to the many technical, ecological and economic requirements of integrated waste management on a regional level. As long as industry and consumers produce waste, an infrastructure is needed for their proper treatment and detoxification and for the secure and continuing disposal of residues (Hunt, 1990). The idea of producer’s responsibility was realized by swinging or reallocating the financial burden for the appropriate treatment or recycling of end-of-life products to manufacturers. This move established a new line of communication between the environmental sector and the manufacturing segments of society. In this scheme, waste managers convey information concerning designs for recycling and the design for disposal upstream to producers and manufacturers, thereby advocating the cause of the environment’s capacities and environmental constraints (Deyle, 1990). Today, the waste management industry is highly conscious and responsive of the significance of social aspects. These include, among others, the siting of facilities and introduction of novel collection schemes, educating consumers, training workers and staff,

Description of the current brand - Assignment Example Second, its iconic Cadillac caters for the high-end market (General Motors 1). Thirdly, Chevrolet, GMC and Opel cater for the middle class market segment (General Motors 1). The multiple brands enable the organization to increase its product offering, a key source of competitive advantage in the motor industry. In addition, it enables it to compete in different parts of the world due to differences in consumer needs. In addition, the organization has sub-brands.

The Rule of Law Essay Example | Topics and Well Written Essays - 1250 words

The Rule of Law - Essay Example Nevertheless, under all contexts that the concept of the Rule of Law should be applied, it anticipates two major aspects; fairness and equality. The meaning of the Rule of Law can be broken down into different contexts, where the first two contexts adheres to the proposition by Webley & Samuels, 2012, that â€Å"The rule of law is a doctrine†, while the third context in which the Rule of Law can derive its meaning, is pitched on the other proposition by Webley & Samuels, 2012, that â€Å"The rule of law is a theory†. Thus, the Rule of Law can be applied in the first context to mean â€Å"according to the law†. Under this context, the Rule of Law is then applied to mean that no individual, regardless of the social status or the position of power they hold in the society, can be subject to a form of punishment that is not in accordance with laws that are well established and clearly and procedurally defined3. This context of the application of the rule of law there fore means that any criminal charges leveled against an entity, be it an individual, a group or an organization must be in line with laws that are well-established and which are clearly understood by the entity, and whose procedure is well known. Therefore, this context of the law anticipates the application of the law to be aligned with the existing doctrines. This prevents an individual or an entity from being punished for any violation that is not punishable by the law4. Relevant case: Papachristou v. City of Jacksonville, 405 U.S. 156, 92 S. Ct. 839, 31 L. Ed. 2d 110 [1972] The Papachristou v. Jacksonville is case in relation to a vagrancy ordinance enacted by the city of Jacksonville in Florida State, where the law prohibited a large form of freelance activities, which included strolling, wandering and moving from place to place, without any lawful intent or object5. The defendant, Papachristou, was among eight other individuals that were arrested and charged with vagrancy in a court of law in Jacksonville, city, for disorderly loitering. Upon an appeal in the United States Supreme Court, the court declared that the Jacksonville ordinance was largely vague constitutionally, since the ordinance did not create any distinction between the illegal and the innocent activities, thus could end-up criminalizing innocent movement activities such as walking at night or habitual movement which had no visible intent5. This vagueness granted the police arbitrary powers to determine which activities they would interpret as lawful, and which ones to declare innocent, following the lack of well-established laws, which are clearly understood by the entity, and whose procedure is well known5. The Supreme Court therefore held that the defendant would not be criminally liable, under such vague law. The second context under which the rule of law can be confidently applied is to mean; â€Å"rule under the law†6. Here, the concept of the Rule of Law would therefore mean that no one is above the law, and thus no one has the freedom to apply law arbitrarily, even when such an entity is the one formulating such laws. Therefore, the second context of the rule of law anticipates that all individuals and entities will be subjected to equal treatment by the law, and thus no one can be favored, and no one can be prejudiced by the same law, regardless of

4.How do the Homeric epics, the Illiad and the Odyssey differ from Essay

4.How do the Homeric epics, the Illiad and the Odyssey differ from each other in their depiction of Greek culture and values - Essay Example n of vices and goodness, strength and weakness, and betrayals and friendships yet all these aspects of human life amalgamate in a manner that each aspect provides the readers with a variety of moral lessons to be learned. Homer in both of his works applies the same phenomenon and deals with two paradoxical situations and presents the readers with two highly contrasting scenarios although both the works project the some good and bad values and culture of the same Greek society. Homer utilizes the plot, setting, character and their actions as a tool in order to depict two different personal interpretations of the Greek society and its culture and values. Homer’s epic Iliad is based on the War of Troy. This piece of literature deals with warfare, bloodshed and revenge. The poem depicts a tale of a war that is fought between Greek King Agamemnon and the Trojans. Homer in his depiction of the whole scenario of the war incorporates and explores a variety of aspects of Greek values and culture. These aspects include greed, pride and deception. Greed and lust are two of the major seven sins that exist in this world. Consequently the Greek society was also engulfed in these sins and a common practice of these vices was also observed amongst portrayal of various characters in Greek Literature. Homer also assimilates this concept in his poem and presents the adverse and fatalistic affects of practicing such vices through the condition of the Greek troops when Achilles refuses to fight for Agamemnon. The reason behind this was because of Agamemnon’s desire to Briseis who was awarded to Achilles. Hence the greed and desire of Agamemnon leads to Achilles refusal and consequently the Greeks lose a large number of their warriors in the beginning. Through Achilles character Homer depicts another vice that was common in Greek Society i.e. Pride. So it can be perceived that the reason for the loss of a large number of The Achaean men and the death of Achilles closest friend
