Evil in the Environment Essay Example for Free

Evil in the Environment Essay John Locke is a philosopher known for introducing various significant concepts to different fields of studies. His work encompasses the fields of psychology, political science, and philosophy. One of his main contributions is his assertion that the human mind is completely empirical.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   This principle would lead one to believe that every human being is born into this world having the same capacity. All human minds are empty slates (tabula rasa) when one is just born. (Hooker, 1999) Behavior is acquired through the various empirical experiences that a human being undergoes. Moral behavior stems from an individual’s empirical experiences. (Hooker, 1999) As such, it can be assumed that all immoral behavior or all â€Å"evil† is the product of the environment rather than individual. (Hooker, 1999) Such line of reasoning will lead us to assume that evil from the environment can be eradicated by a simple change in human thinking and behavior. This is known as the third â€Å"premise† of the enlightenment thinkers.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The said premise remains to be significant in today’s time and age. For one, it helps people today realize that the evil that pervades in society today can be erased by humans themselves. Moreover, it teaches society that there is still hope for a better world and the fulfillment of such dreams lies in the reformation of human beings and society itself.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The primary effect of such premise on society is that it gives the responsibility for the evil in the world on the shoulders of people. Fingers cannot be pointed to the heavens or to other creatures to blame them for the evil that continues to exist in the world. Rather, the premise asserts that the evil in the world is the product of human misbehavior. Human wrong doing has created the immorality that exists in the world today. However, the most important lesson that Locke’s principle teaches us today is that just as the responsibility for the evil in the world lies in our hands, so does the responsibility to change and eradicate such evil.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   There are many ways by which humans can reform and change their environment. Locke had asserted that education is the primary way by which the moral and intellectual character of the human being can be changed for the better. (Hooker, 1999) Such assertion remains to be significant in today’s society. What the premise tells us is that education is even more valuable today for it is the way by which the world can be made better. Education exists not simply for the betterment of the individual’s own life. It is not for the sole purpose of helping someone find a better job, a better way of life. Education’s primary purpose is to help every human being to determine how he can help make the world a better place. It is through education that society can reform its ways and help remove evil from the environment. Thus, the role of education is society is exemplified by the third â€Å"premise.† The role of education becomes ever more important and significant basing on what has been stated in the premise. The future of today’s society lies in the hands of human beings. The betterment of the world and the eradication of evil are the responsibilities of all human beings. Just as they can create evil, they can erase them. Reformation of one’s ways is the manner by which evil in our â€Å"faulty environment† can be obliterated. Works Cited: Hooker, Richard.

Huck Finn Paper :: essays research papers fc

How would you like to have a drunk, abusive father? Well in Huckleberry Finn’s everyday life that’s what he has to deal with. Huck‘s father, which he calls Pap, has a really bad drinking problem which adds on to his abusive ways. In this story Huck inherited a large sum of money and the towns people knew that Pap would be coming for him and the money. Pap is characterized different from the novel, the movie, and Big River, can he really be compassionate? Pap seems to be victimized by the government as the town drunk and not a good role model for his son, but it turns around when he shows compassion when he thinks Huck has died.   Ã‚  Ã‚  Ã‚  Ã‚  In the movie Huck portrays his death so he could escape his abusive father. When Pap arrives to the made up murder scene he seems very upset. Pap started crying and screaming at the thought of his son being murdered. The money that Huck inherited was the driving force for Pap to be reunited with him. The made up death however shows that Pap wanted to be a part of Huck’s life. Pap wanted what was best for Huck. It seemed like Pap wanted to be a part of Huck’s life that’s why he brought Huck out to the cabin to where no one could civilize him.   Ã‚  Ã‚  Ã‚  Ã‚  In the novel, Pap didn’t seem to care about Huck.

Huck was in a good home, living with Widow Douglas and Mrs. Watson; he was actually getting educated and the positive teaching such as praying as he should. â€Å"She told me to pray everyday† (Twain 12). Pap didn’t want that; he didn’t feel the need for his son to be educated if he wasn’t. â€Å"You’re educated, too, they say--can read and write. You think you’re better’n your father, now, don’t you, because he can’t?† (Twain 21). Even though Pap was very abusive, a drunk and seemed to be really mean, he struggle d through the death of his son.

Emotional Marketing: Necessity of Today’s Marketing Management

The purpose of this paper is to write an analysis of an article that discusses an aspect of marketing management. During my research I was attracted to an article by James Cooper Titled, ‘Emotional Marketing as the Basis of Your Promotions’; after reading Coopers article I found Emotional Marketing to be interesting, but his article did not provide enough data to satisfy my interest in Emotional Marketing . So, rather than write about a single article, I have chosen to write about the topic of Emotional Marketing and its necessity in today’s Marketing Management. Marketing mangers must understand that if the consumers’ emotions are addressed in the right way they could get more loyal customers. This has unlashed the approach to marketing which was termed as â€Å"Emotional Marketing† (Drypen). Cooper points out that, â€Å"Marketing to today’s consumers is a challenging business because you are no longer listing the specifications of products and services. Instead you are meeting people on an emotional level to break into their consumer awareness†. As part of a company’s marketing strategy producers need to realize that there is a strong emotional connect between consumers / customers and the products they use. Brands that don't make emotional connections with their prospects and customers will eventually lose out to those that do. The practice of emotional marketing as it relates to value proposition is all about getting your target audience to connect with your product, service, and brand at a very basic and fundamental level – the level of emotions. When building customer value, emotional marketing can be used in influencing customer perceived value and total customer benefit. Some examples of firms that are successful in this application can be seen with top brands such as Starbucks, Porsche, and so on. These products and services make an emotional connection with the people they serve. They have met the challenge of identifying how its products/services can connect emotionally. They have explored what type of experience their product can offer its customers and the perceived value to customer above the firm’s competitors. Emotional marketing can only take place once the company delivers a user experience that represents its purpose. Once the company is able to deliver on that promise, it can market the experience to consumer prospects. Companies must leverage: customer testimonials, word-of-mouth, discussion forums, and trials (marketingscoop). Ideally the company wants its products or services to deliver an experience, and gets prospects to participate along with having the experience themselves. Emotional marketing is a powerful strategy if you can deliver a strong customer experience, thus, leveraging the experience to maximize customer satisfaction in the long run. On the other hand, there are the companies that use emotional marketing when customers are having a not so positive customer experience. These companies take advantage during times of crisis and turmoil. An example of this is appealing to the public during an epidemic or natural disaster and offering short term solutions. Many times the products or services offered are not even effective, nor do they provide the experience the customer desires. Furthermore, the customers’ negative experience is just the opportunity that some companies are looking for to capitalize on short run profit maximization. Leveraging emotional marketing can help in evaluating and selecting market segments to exploit. If and when the marketing/promotion appeals to the emotional aspects of customers the companies, in some cases, can move toward targeting a ‘supersegment’. For example, many symphony orchestras target people who have broad cultural interests, rather than those who only regularly attend concerts (Kotler & Keller pg 229). The product appeal is more toward a cultural or emotion interest rather than that of a physiological need. Emotion acts as a catalyst in the engine of the purchase decision process. Through experience and learning, people acquire attitudes. These in turn influence buying behavior (Kotler & Keller, pg 170). This is important since favorable and unfavorable experiences trigger emotional feeling toward a product or service being marketed. Cooper’s article, â€Å"Emotional Marketing as the Basis of Your Promotions† only touched on promotion of the product as it appeals to emotional marketing. After further research I found that emotional marketing throughout the marketing process is important in its application to: marketing strategy, customer value, target markets, brands, market segment, customer satisfaction and purchasing decisions. In conclusion, marketing managers must understand that costumers get attracted to products which effect there feelings. Companies which want to stand above the competition have to leverage emotional marketing so as to increase market share. Effective development in emotional marketing can shift a marketing challenger or market follower to position of market leader. Thus, making emotional marketing a necessity of today’s marketing management.

How new words are created in English

Knowing the relationships of sound and meaning of each word, we will be able to understand how new words are created in English. Basically, there are several ways that new words can be created: by inventing a new sound sequence and referring it to a meaning, by altering the meaning of an existing word without altering the pronunciation, or by modify or expanding the sound sequence of an existing word. The first way refers to acronyms, which are words formed from the initial letters of a phrase. For instance, IPA is the abbreviation of International Phonetic Alphabet, whereas others, such as NASA from National Aeronautics and Space Administration, are pronounced like words instead of a succession of letter names. Some acronyms are written lowercase, causing people to forget their origins and becoming entire new independent words. For instance, ‘radar' derives from radio detecting and ranging. Also, parts of words are clipped to become shorter; for example, examination was shortened as ‘exam', ‘phone' from telephone, and ‘flu' from influenza. Last, there are blends which are words made by combining syllables from different words. Examples are ‘motel' from the first syllable of motor plus the second syllable of hotel, ‘infotainment' from the first two syllables of information plus the last two syllables of entertainment. Second, the meaning of a word may be generalized, for example, ‘Kleenex' is originally a brand name for facial tissue. But now it refers to facial tissue in general. ‘Silhouette', now means dark outline being seen against light, was taken from the name of Etienne de Silhouette. Also, we can change the category of words, such as ‘people', which is a noun mostly meaning the plural of person, can also be a verb meaning populate a place. Finally, there is the metaphorical extension of existing words, like to ‘chew' on an idea meaning to ponder on it. Another way is to compound individual words. Two nouns, say, honey and moon, are joined together to form the compound noun, ‘honeymoon'. The adjective mobile is joined with the noun phone to form the compound noun ‘mobile phone'. The preposition under is joined with wear to form the compound noun ‘underwear'. The verb play is joined with the noun ground to form the compound noun ‘playground'. As for all these compounds, the last word of each compound gives the collective meaning. New words are also formed by borrowing form other languages, and the words have been assimilated into English. For example, there are words from French, like brochure, from Japanese, like sushi, from German, like beer, and so on. Moreover, some words are created by onomatopoeia. Humans mimic the sounds of nature and use these sounds as referents for the sources of sound, such as buzz, whiz.

Thinking Problem solving and Team building

Thinking Problem solving and Team building Introduction Working in one of the industries that fall in the category of health sector is all what I wanted and demanded since childhood, however, my passionate and interests were not directed to specific institution or organization as I went through the primary course of education.Advertising We will write a custom essay sample on Thinking Problem solving and Team building specifically for you for only $16.05 $11/page Learn More Despise lack of specificity in these earlier years of career building; I did not wave from looking forward to the establishing of the future professional foundation in the field of health service provision, as it was evidently affirmed by the exceptional performance in mathematics and science subjects. Therefore, it was not a surprise in my life to find graduating with a higher diploma in engineering pharmacy, which resulted after a compacted 17 years of study. Having set high goals in my career and professional development, I fel t that graduating from the higher learning institution acted as a mark of one the major achievements in life, while it still meant a lot in the transition of my life. As a matter of fact, I didn’t want to procrastinate in getting myself within the job systems, and being driven by enthusiasm and ambition to practice all that I had gained from academic work, I relentlessly made applications to all those potential companies which I believed could offer or were having an opportunity for a pharmaceutical engineer, beside considering their ability to offering a good working environment to the entire company’s labor force. After trying severally in sending applications to a number of such organizations of interest, some corresponded by sending regrets, other kept dumb-mute without replying, while a few called for an interview in which I would fail some, while others we disagreed in terms of package remuneration and other benefits. Though the whole hassle for a job was not eas e, fraught of confounding situations as expressed above, this circumstance was a short lived one, as XYZ pharmaceutical company soon accepted me by we agreeing to the terms and conditions for each other, thus entering into the first contract. Overview of the job environment The accomplishment of the job deal gave a new feel to both us. Being the first one, it meant a lot in my side, especially in gaining enormous experience while making the organizations operations to run smoothly through the services that I promised to offer. In signing the contract with the XYZ pharmaceutical company, I agreed to delivery my services in a number of ways.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More First and foremost, as a person endowed with the knowledge and a little bit of experience in offering engineering services for a range of pharmaceutical machines and equipments, it was my obligatio n to ensure that all pharmaceutical packaging machines of the organization were in proper working conditions. This appeared to be the major responsibility that was given to me by the organization, which I did wholeheartedly. Here, I worked closely and concentrated more in dispensing my engineering services by servicing the packaging machines. Though being new in the field, I did find or encounter much difficulty in delivering in this particular task. I think and believe that this was because I had wide knowledge in the field of work and some clues or hints gained through experimental work that I did in the course of schooling. In addition also I felt attracted to working in this place as it demanded little movements from one place to another. However, the little movements wasn’t an advantage because I did not like walking, but understand that long resting is a thing which I have hated in my life, for it encourages laziness, and bring a lot of problems to humans especially tho se non-infectious diseases such as obesity and edema. On the contrary way of thinking, I held less movement as an added advantage in the workplace for somebody new in job tasks, more so in a high and sensitive position concerned with assurance and control of quality of the company’s products. While understanding the related effects and consequences of producing products of poor quality for the organizations, I took the cutting down of movements within the organization and working from a single place as a way that led to sparing of some extra time for my personal-work related activities. In order to ensure that there was maintenance and enhancement of quality products within the manufacturing and production of goods in the organizations, I at first utilized the extra time diligently and serious working on those areas which I knew posed considerable difficulties in understanding them during the course of study. Moreover, this spared time was also of significance importance as i t also gave me the chance to familiarize myself with many things involved in a real workplace environment, including tenets and regulations that applied to the company’s employees at different circumstances. Within a very short working period after signing my employment contract with the company, it was evident that I had gained adequate knowledge and experience to service and work on any machine particularly any of the packaging type of machine. Thus, there was a more gain of interest in deliberating on my tasks of machine repairing, which triggered the need of moving from being so much specialized on one working point station to a more general one.Advertising We will write a custom essay sample on Thinking Problem solving and Team building specifically for you for only $16.05 $11/page Learn More So, I sometime moved around the organization’s departments looking if there were any of the familiar machines that had broken down to service it. Fo r that matter, a part from serving as chief machine repairer for the major packaging machine of the organization, I also went on attending to several other small machines and equipments which were being used within the organization to accomplish various other packaging tasks. Truly, it was not to my surprise that every time I tried to get a tour within the various departments dealing with such related machine, I found several of them had broken down depicting that the way the company might have been suffering and incurring a lot of losses due to the issue of machine failure. Revelation of Problems The service that I offered to the XYZ pharmaceutical company appeared to be in higher demand than the company’s managerial team and I could have perceived before. The decision to move around in search for the broken packaging equipments and miniature machines led to the realization that the broken machines to be serviced were more than what the chief company machine supervisor, whom was one of my interviewers had understood or revealed. Though I was busy in most of the time working hard to cope with the tight time working conditions of the company, there were also some hours for break, lunch and some leisure which were created officially for renewal of energy in our body. As most of the workers did not get out of their working stations during breaks and lunch hour periods, I planned spending part of these hours for social purpose. Despite the fear of being a new employee in the company, I pretended that I was looking for those broken down packaging machine, and this worked to the best of attaining the hidden intentions. It sometimes appeared to me that I was bothering a few of the workers when I stepped in their stations or offices, especially those who were work overloaded, and wanted to recover or catch up with time certainly for deadlines that were nigh.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More However, I used the gained communication skills to get over the barrier of making friendships; thus, we found it necessary to share a little bit of our past even if it meant a mere simple and short introduction which included just our names and the kind of job or position each of us was doing for the organization. The decision to pay visits to the many offices and work stations had a double to triple fruitfulness. That is, when I shared with most of the colleagues of the kind of job and professional area of my specialization, almost eight five percent of them showed interest and requested for my assistance. There were those who wanted me to service and repair simple equipments, while others needed me to work on certain machines which looked to be complex machines to them such a photocopiers, printers and to some extend computer categories, depending on the office they held. I tried all that I can to repair those with simple problems according to my knowledge and experience, while av oiding to disappoint my new colleagues and allies by giving assured appointments for the complicated problems. The overall results showed that the organization had suffered a lot in several ways other than just having their machine broken down. While many of the corporation’s machines were non-functioning or having problems that were generally not reported, it depicted that there was an overall problem of communication barriers among individuals and departments whose works were core to the contributions of the company’s production and efficiencies. The matter became evident when I volunteered to work and assist the company on having a routinely weekly repair for the installed machines. It was a tiresome tasks resulting from immeasurable movements, that is, moving from office to office within a department and more so from one department to another. This not only counted towards wastage of one’s energy, but it also led to a lot of time wastage on collecting the re pair information requests from the different notice boxes which were not strategically located in the various departments. Furthermore, the manual system of receiving the documents took me long time to draft and enter the data to my storage records for future reference, scheduling and any other need that might arise in the course of the business operation. Due to the use of manual data and information system within the organization, much of the work remained undone leading to the company lagging behind in most of their operations. With this kind of system being in place, the supply, accounting and the store departments were greatly affected as they could not keep complete, compiled information without having received the data and information in time. Seeing the vaguely system and hardship that the organization was going through, I did not hesitate in proposing of new communication methodology. The sense was overt to every member of the organization and within four months of my emplo yment in the organization, plans instilled through a collaborative approach of departmental staffs and junior employees were underway towards the introduction of new project on information technology, primarily aimed at off setting the problem of data and information transfers in their communications. The inclusions of all parties in the proposing and introducing the programs was of paramount significance in assuring that not body had to be affected by the employment of the new technology. According to me, this establish trust and confidence among member parties, while at the same time showing concern and care for each others’ future and welfare, thus, paving the way for speedy implementation of the project. Team building On critical assess of the organizations, it appeared that they were several issues that needed to be resolved within the organization. Following group and employee’s discussions among themselves and negotiations with the managerial team, it was discov ered that most of the employees required knowing more than just simple single issue their area of operations. For instance, it was suggested that machine operators should get to know a bit of simple repair methods, while secretaries were to gain to some extend the knowledge and experience on managerial professions so as to make the company operate efficiently and perform excellently. For the purpose of accomplishing this goal, the involved parties negotiated for the best way to learn the new skills, however with limited time available for the management team to offer its employees as a way of motivating them, the parties finally decided to create sacrificial extra time for them to learn and get acquainted with the new skills. In departmental groups, each of them established their leaders and through closely working relationship with volunteer senior managerial team formed by person whom had already acquired the knowledge and skills needed in the specific groups, they kicked off on a serious training sessions that would transform the organization in a number of ways. Conclusion In conclusion, it can be stated that problems are always there in organizations, and sometime this exist even without being noticed by the seniors and company executives. This situation was not quite different for the XYZ pharmaceutical company, which believed that the only problem they had was only concerned with repairing of packaging machines. However, the establishment and building of a team is a critical to solving many problems existing in organization, including even those hidden problems that derail the delivery of services and/or productions of products. As I reflect on my case, I become convinced and confident that anybody holding any position in an organization can bring a lot of transformational changes directly and indirectly through establishment/building of a team, as long as the party possesses the necessary skills and knowledge needed.

Prehistoric Life During the Devonian Period

Prehistoric Life During the Devonian Period From a human perspective, the Devonian period was a crucial time for the evolution of vertebrate life: this was the period in geological history when the first tetrapods climbed out of the primordial seas and began to colonize dry land. The Devonian occupied the middle part of the Paleozoic Era (542-250 million years ago), preceded by the Cambrian, Ordovician and Silurian periods and followed by the Carboniferous and Permian periods. Climate and Geography The global climate during the Devonian period was surprisingly mild, with average ocean temperatures of only 80 to 85 degrees Fahrenheit (compared to as high as 120 degrees during the preceding Ordovician and Silurian periods). The North and South Poles were only marginally cooler than the areas closer to the equator, and there were no ice caps; the only glaciers were to be found atop high mountain ranges. The smallish continents of Laurentia and Baltica gradually merged to form Euramerica, while the giant Gondwana (which was destined to break apart millions of years later into Africa, South America, Antarctica, and Australia) continued its slow southward drift. Terrestrial Life Vertebrates. It was during the Devonian period that the archetypal evolutionary event in the history of life  took place: the adaptation of lobe-finned fish to life on dry land. The two best candidates for the earliest tetrapods (four-footed vertebrates) are Acanthostega and Ichthyostega, which themselves evolved from earlier, exclusively marine vertebrates like Tiktaalik and Panderichthys. Surprisingly, many of these early tetrapods possessed seven or eight digits on each of their feet, meaning they represented dead ends in evolution since all terrestrial vertebrates on earth today employ the five-finger, five-toe body plan. Invertebrates. Although tetrapods were certainly the biggest news of the Devonian period, they werent the only animals that colonized  dry land. There was also a wide array of small arthropods, worms, flightless insects and other pesky invertebrates, which took advantage of the complex terrestrial plant ecosystems that started to develop at this time to gradually spread inland (though still not too far away from bodies of water). During this time, though, the vast bulk of life on earth lived deep in the water. Marine Life The Devonian period marked both the apex and the extinction of the placoderms, prehistoric fish characterized by their tough armor plating (some placoderms, such as the enormous Dunkleosteus, attained weights of three or four tons). As noted above, the Devonian also teemed with lobe-finned fish, from which the first tetrapods evolved, as well as relatively new ray-finned fish, the most populous family of fish on earth today. Relatively small sharkssuch as the bizarrely ornamented Stethacanthus and the weirdly scaleless Cladoselachewere an increasingly common sight in the Devonian seas. Invertebrates like sponges and corals continued to flourish, but the ranks of the trilobites were thinned out, and only the giant eurypterids (invertebrate sea scorpions) successfully competed with vertebrate sharks for prey. Plant Life It was during the Devonian period that the temperate regions of the earths evolving continents first became truly green. The Devonian witnessed the first significant jungles and forests, the spread of which was aided by the evolutionary competition among plants to gather as much sunlight as possible (in a dense forest canopy, a tall tree has a significant advantage in harvesting energy over a tiny shrub). The trees of the late Devonian period were the first to evolve rudimentary bark (to support their weight and protect their trunks), as well as robust internal water-conduction mechanisms that helped to counteract the force of gravity. The End-Devonian Extinction The end of the Devonian period ushered in the second great extinction of prehistoric life on earth, the first being the mass extinction event at the end of the Ordovician period. Not all animal groups were affected equally by the End-Devonian Extinction: reef-dwelling placoderms and trilobites were especially vulnerable, but deep-sea organisms escaped relatively unscathed. The evidence is sketchy, but many paleontologists believe that the Devonian extinction was caused by multiple meteor impacts, debris from which may have poisoned the surfaces of lakes, oceans, and rivers.

Cambrian Explosion Research Paper Example | Topics and Well Written Essays - 1500 words - 2

Cambrian Explosion - Research Paper Example Some of the animals with basic animal bodies include arthropods such as insects, crustaceans, and trio-bites, cnidarians like jellyfish and corals, mollusks such as shellfish and squids, echinoderms like sea urchins and sea star, and chordates such as vertebrates. The Cambrian exposition occurred during the Cambrian period that began 570 million years ago and ended 510 million years. According to Meyer et al. (2001), the Cambrian exposition occurred within a window of 20 to 40 million years during the Cambrian period. According to BBC, (2015), the Cambrian period began 545 million years ago and ended 495 million years ago. The Cambrian period was characterized by the sudden emergence of living organisms in the sea. Although geologists are lucky to identify some Cambrian fossils, there was no life on the land. According to Darwin’s theory, the Cambrian exposition is based on the existence of changing environmental conditions that cause genetic modification of genes. The major cause of the Cambrian exposition is believed to be a rapid increase in the oxygen level in the atmosphere. An increase in oxygen level in the atmosphere occurred approximately 2.3 or 3 million years when numerous microorganisms released oxygen to the atmosphere through photosynthesis. The second oxygen increase event occurred approximately one billion years ago and resulted in the development of various complex organisms during the Cambrian period. The link between the increase in oxygen levels and development of complex organisms is confirmed by various past events. For instance, the oxygen concentration is believed to have increased from 10 % to 21% in the past 425 million years. The event resulted in the evolution of vertebrates thus attaining essential features. Secondly, high oxygen concentration level in the atmosphere resulted in an increase in insect size (Koch & Britton, 2009). According to Penumaka (2011), the earth was covered by glacier 580 million years ago thus
