History of television an its effects on soceity

History of television an its effects on soceity Credit can not be given to one single person for the invention of television. Its development was fueled by many different inventors working on individual projects. Many of these inventors where not trying to produce a television at all but their achievements were applied by others to help make image transmission possible. One of the first major breakthroughs was made in 1884 by Paul Nipkow. The "electric telescope" that he created used rotating metal disks and had the ability to transmit images over an electric wire with 18 lines of resolution. In 1906 Boris Rosing would further the technology by combining it with the Audion vacuum tube, and a cathode ray tube to produce early methods of electronically scanning and reproducing images.In 1925 American Charles Jenkins and John Baird from Scotland, each demonstrate the mechanical transmissions of images over wire circuits. Baird would become the first person to transmit moving silhouette images using a mechanical system based on Nipkow 's disk, and Jenkins would receive the first television license from the Federal Radio Commission in 1928.Vladimir Zworykin demonstrates electronic televisi...By 1929 another inventor Vladimir Zworykin uses his kinescope invention to demonstrate the first practical system for both the transmission and reception of images. John Baird opens up the first television studio but the quality of his transmissions were poor. Iowa State University began broadcasting television programs in 1933, there were only around 200 television sets though to exist in the world at this time. By 1937 CBS and the BBC would also begin broadcasting black and white programming. The demand for color sets was answered by Peter Goldmark in 1940.His television created all other colors from using a color wheel dived into red green and blue and could produce 343 lines of resolution. Many people were now enjoying the modern convenience...

What Makes For a Bad College Recommendation

What Makes For a Bad College Recommendation SAT / ACT Prep Online Guides and Tips Generally speaking, no one is going to purposely hurt your college application and write a negative recommendation (that'd be an oxymoron). If for some reason someone feels like they can't honestly recommend you, they likely would decline or suggest someone else. That being said, there can still be bad recommendations from writers with good intentions. And admissions officers can spot them from a mile away. These letters certainly don't help your application, and they could even hurt your chances of getting accepted. Let's take a closer look at what features make for a "bad" recommendation. A Bad Letter is Lukewarm Again, I'd like to think that no one would agree to provide you with a letter of recommendation and then write damaging, critical things behind your back. This would be unethical, and a pretty mean thing to do. As long as you choose your recommenders carefully, you shouldn't have any concerns about that. The more common problem occurs if the letter writer comes off as unenthusiastic or lukewarm in her recommendation. To admissions officers who have read hundreds, if not thousands, of letters, it's pretty easy to separate the mediocre letters from the great ones. Mediocre letters might be short and generic. They might not express admiration of your academic ability or personal qualities, or express much confidence in what you'll do at college and beyond. Rather than revealing new insights into who you are, bad recommendation letters might just state facts and figures. When I was in high school, I asked a history teacher for a college recommendation. To my surprise (and disappointment), he gave me a generic letter and told me to go through and change the "he's" to "she's" to "customize" it. Needless to say, I quickly asked someone else. In this case, it would have been a good idea to seek advice from my counselor or others about which teachers take the time to write strong letters and which ones use a form letter for all their students. Admissions officers expect you to be thoughtful about who you ask for your recommendation. If you present a letter that reads as though the writer didn't have much to say or was unmotivated to recommend you, then it suggests that you either didn't put much thought into your rec letters or, worse, that this was the best recommendation you could get. If you're limited in your options for recommenders because your school has large class sizes or counselor caseloads, there are still things you can do to connect with your recommenders, like setting up meetings, writing a detailed brag sheet, or sending a supplemental recommendation. Some phrases that could come off as lukewarm include "above average" or "relatively good student." A recommender might communicate that you still have room to grow (who doesn't?), but focusing on this could also communicate that she's not too impressed with what you've done so far. This introduction is an example of a lukewarm start to a letter that doesn't sound too animated, interested, or like the writer tried to say much beyond the obvious. I'm writing to recommend Sylvia for admission to your undergraduate program. I had Sylvia in my 11th grade chemistry class. She was an above average student with an interest in science. Sylvia participated well in class and was reliable with her homework and other assignments. She performed above average throughout the year. Poor Sylvia. Her recommender didn't even say "strongly" or "highly" recommend. This introduction sounds unimpressed and unspecific. Another feature of a letter that's ineffective is that it doesn't go beyond your resume. A Bad Letter Repeats Your Resume A recommendation letter is not supposed to copy your resume. This is a common mistake of recommenders, simply listing out your grades, rank, clubs, and/or awards. Admissions officers already know all this, though. They see it in your application, or maybe you've talked about a particularly significant involvement in your personal essay. If this was all they wanted to see, then there would be no point to requiring recommendation letters. Instead, a letter should add to your story by illustrating who you are, including your values, motivations, and goals for the future. It can describe meaningful observations and interactions that give insight into your character. It adds nuance to your story, speaking to your attitude towards learning and to your personality. Plus, a strong recommendation letter shows that you've connected with your teachers and contributed to your school community. This indicates that you'll do the same once you arrive to college, a positive sign for admissions officers looking to build a dynamic and harmonious class. Here's an example of a recommendation that relies on facts and figures, but doesn't go much beyond the information that's already present in the rest of your application. Tom played football throughout all four years of high school, winning the honor of Most Valuable Player in junior year. When he wasn't practicing football, he was in Woodworking Club, which he participated in during junior and senior year. Tom has challenged himself with college prep and honors classes, earning a GPA of 3.5. He was recognized for his effort by his 10th grade English teacher, who awarded him the Best Effort certificate. Outside of school, Tom works part-time at his father's car dealership. Admissions officers should already know all this by reading Tom's Common Application. This letter just turns bullet points into full sentences. Another feature of an ineffective recommendation is that it comes off as unspecific and unsupported. About as helpful as using Apple Maps. A Bad Letter is Unspecific As discussed above, a recommendation letter should go beyond the obvious and reveal something about your commitments and character. A letter that speaks in generalities doesn't accomplish that, nor does it paint a picture of you for its readers. While it may use general adjectives to describe you, like driven or ambitious, these adjectives don't mean all that much without examples. Like a persuasive essay where you need supporting examples to prove your thesis, a recommendation letter should relate anecdotes that demonstrate something meaningful about you and provide evidence for its assertions. A bad letter might say, Abby is a hard worker. A stronger letter would say, Abby's hard work and persistence endured throughout her in depth, year long research project on the decline of the fishing industry in 19th century Gloucester. (It might go further into detail describing her long days digging through the local library's archives and how the recommender sees her conducting historical research at her college's library next year.) Without the examples to back it up, the first sentence about Abby being a hard worker doesn't explain what she works hard to accomplish or how her recommender knows this to be true. It also could be about almost anyone. If the recommendation letter does little to differentiate you from other students with similar credentials, then it hasn't done it's job. A Bad Letter Could Be About Almost Anyone That form letter I got from my history teacher wasn't just riddled with male pronouns, it also barely talked about me. It was full of generic statements about doing well in history class, working hard, and being committed to academics. All that was general, unsupported by examples, and could have been about any number of studentswho did well in history class. The truth about college admissions is that there are more qualified students than there are spots in the class, especially when it comes to highly selective schools that only let a small percentage of students in. Some may share similar academic and extracurricular profiles. They might have the same GPA, same class selection, and similar involvements in clubs and sports. That's why the recommendation letters, along with the student's own personal essay, are so important for distinguishing one student from another. Letters that are general, don't share anecdotes, and list out facts and data could be about any students that share a similar resume. They're flat, boring to read, and suggest that the teacher doesn't know anything personal about the student. Maybe the student just gave her a resume, and she turned the bulletpoints into prose. Finally, another red flag for admissions officers could be if the letter is simply too short. Not only did the recommender not have anything personal to add to the student's recommendation, but she also didn't have much to say at all. Aw. A Bad Letter is Too Short A recommendation letter should be a full page. It shouldn't usually go beyond a page, but it also shouldn't be shorter. Just having an introduction, short body paragraph, and conclusion wouldn't be sufficient. It might fulfill the application requirement, but it wouldn't look good or communicate all that much. If your letter's short, this is immediately noticeable to a reader. It suggests you didn't choose your recommender very well, she doesn't know you, and you didn't give her much material to work with. Instead of making the positive impression that a good letter of recommendation can leave, it feels lacking. Since no one wants her application dragged down by subpar recommendation letters, what can you do to avoid a bad one? Are these documents out of your hands, or do you have some say in the matter? Be proactive, be be, proactive! What to Do to Avoid a Bad Letter of Recommendation Before you even begin making requests for letters of recommendation, you should go into junior year (and high school, for that matter) with a proactive mindset. Participate in class, get to know at least one or two of your teachers well, and talk to them about your educational goals. Demonstrate your interest in a subject by taking on an independent project or joining a club of which that teacher is an advisor. If you're planning to apply to a selective school or for a certain major, showing a specific commitment like this will impress admissions officers and your future recommenders. When you're finally ready to ask, be thoughtful about who you ask. If your teacher seems hesitant at all, it's probably a good idea to thank her and then ask someone else instead. If she has reservations, that will show through in the letter. Ask early in case you need to change track, plus some teachers set quotas and have a first come, first served policy for writing letters. Give them time, at least a month, to put thought into your letter, rather than rushing through a copy so you have something to send in ahead of deadlines. As I should have done before my recommendation mistake, ask your counselor for her recommendations on who writes good letters. Seasoned teachers are often a good choice, especially if they have a reputation for helping students get into their schools of choice. If you've forged a good relationship with a relatively new teacher, it might be beneficial to share your thoughts on what could make your letter outstanding. Whether or not it's appropriate to share resources on letter writing with your recommender is a judgment call, as you wouldn't want to insult the person you're hoping will praise you. You can feel out whether it would be welcome to share guides like this one with your recommender, or whether she already has a strong sense of purpose in her letter writing. Apart from participating in class and talking to your teachers, you can also give them a detailed brag sheet. Share important information that you want them to know about you, along with specific significant experiences or challenges in your life that they could potentially speak about in their letters. Tell them what qualities and interests you're highlighting in the rest of your application, so they can complement your story without repeating too much of it. Above all, make sure your recommender is genuinely happy to help you get accepted to college and will put in the time and effort to craft a thoughtful, specific, and customized letter of recommendation. While your brag sheet can help her out a great deal, she should still have enough material and inspiration from having you in class or school to create an insightful letter of support. What's Next?

In a deductive approach the researcher makes an assumption or theory and then tries to prove his or her theory with the help of the research findings and data. On the other hand, in an inductive approac h the researcher uses practical findings and research results to derive a hypothesis. The research question needs to be apt and to the topic. Research question must not be too elaborative or too restrictive. Too elaborative research question would not be very useful to drive the point and it would be more of an explanation than a question. Too restrictive research question might not cover the scope of the research. The research question must be designed in such a way that it compels for an answer.

An entrepreneur is definitely a leader who leads his company or organization to success and greater heights. But what researcher

Communications Essay Example | Topics and Well Written Essays - 1750 words

Communications - Essay Example It serves as a communication therapy discussing three major themes in communication issues: indicators, findings, and therapy (Reich 153). As with everyone who experienced family talk, it is easy to see how it can go in circles. Family members argue about little trivial matters that sometimes merely started as normal conversations. We hear every single type of complaint like â€Å"she doesn’t like to apologize,† or â€Å"I didn’t do anything wrong so I shouldn’t say sorry,† or â€Å"mom always criticizes everything I do,† or â€Å"he doesn’t appreciate what I do.† (Tannen 5-6) Every single individual experienced times when they tried to say something good yet ended up being misunderstood. This is a commonplace happening, but usually harder when family members or people who are close to each other are involved (Noller and Fitzpatrick 17). It is like giving a person a gift of a nice scented-lotion and, instead of a â€Å"thank yo u,† receive a response that they were offended because it means they smell bad or need more grooming. The real meaning of the message wrapped in the niceness of the gift is taken as a negative hint for the correction of their errors. Even if that was never the message the sender wants to give, the distorted interpretation creates a negative impact upon the relationship of the sender and receiver (Tannen 11-3). No further proof is needed for this pathology of communication problems shown in this scenario and other scenarios similar to this. There is evidence in almost every daily interaction people have with others, and usually, although unfortunately, the closer people are with each other, the greater chances there are for miscommunication (Tannen 21). The author’s intention is to explain the process of conversation, to which interpretation plays a great role. People should not read a single message in one specific context. Most communication process, particularly betwe en those who are closely related to each other, involves a lot more than mere words (Noller and Fitzpatrick 19). In interpreting the sender’s meaning, one should be familiar with all the other aspects of communication. This is the only solution for the issue of misinterpretation. The underlying message --- the meta-message --- has greater effect in communication, whether negative or positive (Tannen 7-8). In the third chapter of the book (67-93), Tannen explores meta-messages in several spoken lines people use, and the differences of these meta-messages in conversations between people in close relationships. Tannen states that the meta-messages in intimate relationships is different because of control continuum and connection continuum (Tannen 11). In the overall message of the third chapter, the solution for miscommunication is simply acknowledging that everything heard and said are potentially vague. The appropriate process in deciphering the message, therefore, is to disam biguate by looking at the core of the message. However, the issues in this process are that a speaker at times intentionally creates the meta-message, or unintentionally create the meta-message, or the receiver imagines a meta-message. This makes the interpretation of meaning a not so simple task, and unless one is able to read minds, the possibility of misunderstanding is big. Therefore, paying attention is important (Reich 153). Even to one who has not studied the art of communication, ideas regarding the surface meaning

Rites of Passage in Henry IV Essay example -- William Shakespeare

A Rite of Passage Rites of passage mark and celebrate important changes in life. For many, this is the transition between adolescence and adulthood. In the play 1 Henry IV, by William Shakespeare, Prince Henry’s transition to adulthood is indicated when he shows his bravery in battle and proves to be an honorable King. The play shifts between two different views that of the Scottish rebels versus the English royalty and the strain between Prince Henry and his father. Throughout the play, Prince Henry develops from a rascal to a responsible adult and by doing so, earns the respect and acceptance from his father King Henry IV. In act one, Shakespeare introduces the idea that Prince Henry is an inadequate heir to the throne. The play opens with King Henry IV, Prince Henry’s father, speaking to his council of a war with Scotland. Quickly the subject of the discussion turns to Prince Henry, or Harry’s, indifference to the affairs of war. The King then compares Harry to Hotspur, son of the Duke of Northumberland in his dialogue: KING. Yea, there thou mak’st me sad, and mak’st me sin (Harry) In envy that my Lord Nothumberland Should be the father to so blest a son, A son who is the theme of honor’s tounge, Amongst a grove the very straightest plant, Who is sweet fortune’s minion and her pride (Hotspur), Whilst I, by looking on the praise of him, See riot and dishonor stain the brow Of my young Harry. O that it could be proved That some night-tripping fairy had exchanged In cradles clothes our children where they lay, (1.1.78-88) King Henry IV is saddened and ashamed of Harry’s drinking and stealing and wonders if he will ever become a capable leader. King Henry IV even questions if some... ... his soliloquy by proving that he is an admirable leader, and fulfils his solemn oath to kill Hotspur which makes his word honorable. Prince Henry completes his rite of passage after his defeat of Hotspur. Henry entered the battle field as a boy and has formed into a responsible adult and an adequate heir to throne. In 1 Henry IV, Prince Henry’s gradual development was evident throughout the play. A comparison of Harry’s character during the first act against Harry in the fifth act almost seems like two different people. Prince Henry has carried out his plan to prove to people that he will be a worthy King by following his father into battle and killing the leader of the rebel army. Prince Henry’s act of bravery marks the transition between the young Henry and the mature Henry but more importantly, has earned Henry the respect and acceptance from his father.

“Spellbound” a Cinematic Representation of Psychoanalysis

The movie â€Å"Spellbound†, directed by Alfred Hitchcock, encompasses several Freudian concepts manifested in the characters; including amnesia, guilt complex, repression, and psychopathology. Psychoanalysis is a major element of the film and is used in the pursuit of â€Å"truth†; the â€Å"truth† being what happened to the real Dr. Edwards. Also, dream work is a major tool used in the film to uncover the â€Å"truth†. Though â€Å"Spellbound† has several characters that embody Freudian concepts, I believe the four main characters are most important. John Ballantyne exemplifies amnesia, guilt complex, and repression; Dr.Constance Peterson represents the process of psychoanalysis; Dr. Burlov is a depiction of Freud; and Dr. Murchison conveys Psychopathology. The film, â€Å"Spellbound†, begins in the setting of green manors, a mental asylum. The head of the facility, Dr. Murchison, is retiring and a famous psychiatrist, Dr. Edwards, is to ta ke his place. Shortly after â€Å"Dr. Edwards† arrives another psychiatrist, Dr. Constance Peterson, discovers that the man claiming to be â€Å"Dr. Edwards† is an imposter. This imposter is suffering from a guilt complex which causes him to be an amnesiac.Thus begins the pursuit of â€Å"truth†, using psychoanalysis, to uncover who the imposter is and what happened to the real Dr. Edwards. We find out that the imposter is John Ballantyne, a patient of Dr. Edwards, and an amnesiac; which is why he believes he is Dr. Edwards in the beginning of the movie. John Ballantyne’s amnesia is related to the guilt complex from which he is suffering. We know that Ballantyne experienced a traumatic event, this triggered repression of memory, bringing conscious truth to the unconscious to protect the mind from the trauma; this caused his amnesia.Dr. Constance Peterson believes that by using psychoanalysis she can tap into Ballantyne’s mnemic trace, or unconsciou s memory, and uncover the Primal scene. The primal scene being the trauma that Ballantyne suffered. Dr. Peterson and Ballantyne embark on a journey, evading the authorities, to answer the question of what happened to the real Dr. Edwards. Dr. Constance Peterson, portraying the process of psychoanalysis, is of course mentored by Dr. Burlov who is a representation of Freud; both aesthetically and conceptually. Dr. Peterson brings Ballantyne to Dr.Burlov to help uncover the aforementioned primal scene. This portion of the film encompasses all aspects of Psychoanalysis. Ballantyne, suffering from amnesia due to his guilt complex and repression, is analyzed by Burlov in a few ways. First Burlov uses transference, saying, â€Å"I’m going to be your father image†, then he uses free association, asking Ballantyne, â€Å"Whatever comes into your head just say what it is†. When Ballantyne has no response Burlov turns to dream work saying, â€Å"maybe you dreamt something ? † This analysis of Ballantyne’s dream, or dream work, is an integral scene of the film.The dream sequence, designed by Salvador Dali, contains several symbols; these symbols allude to the truth which is buried in Ballantyne’s unconscious. Freud believed that dreams were the connection to the unconscious, and tapping into it could relieve someone of their psychological sufferings. The most important symbols are the bearded man, the proprietor, the sloping roof, the wings, and the wheel. The bearded man is Dr. Edwards. The sloping roof symbolizes a mountain. Dr. Peterson and Burlov deduce that the trauma occurred at a ski resort. The symbolism of the wings and sloping roof gives them the name of the resort, Gabriel Valley.Constance, Ballantyne, and Burlov go to Gabriel Valley to trigger memory. Ballantyne suddenly remembers that at the bottom of the hill there is a cliff, over which Dr. Edwards fell. It is also revealed that Ballantyne’s true primal scene is not the trauma of Dr. Edwards’ death. His true primal scene is the recollected memory of sliding down a rail and accidentally killing his brother, this is the initial trauma that causes his guilt complex, which is why he was a patient of Dr. Edwards. When Dr. Edwards’ body is uncovered it is discovered that he did not die from the fall, but from a gunshot. Ballantyne is sentenced and incarcerated.This does not sit well with Constance. She looks over her notes on Ballantyne’s dream and realizes that the proprietor is Dr. Murchison, the chimney he hid behind was a tree, and the wheel is a revolver which he used to kill Dr. Edwards. Dr. Murchison is clearly an example of psychopathology. In conclusion, Hitchcock’s â€Å"Spellbound† is a cinematic representation of many Freudian concepts such as psychoanalysis, dream work, and guilt complex. The characters embody these concepts. The pursuit of â€Å"truth† is a major element of the film; this is also the case in psychoanalysis, which is used to uncover repressed memories; or the â€Å"truth†.

The animals in this category share many characteristics which are bilateral symmetry,two cell layers, tissues and organs, lack a cavity, posses a through gut with a mouth and anus monomeric and highly variable bodies, may posses shell and calcareous spicules, has a nervous system with a circum-oesophageal ring, ganglia and paired nerve chords, open circulatory systems with a heart and an aorta, has gaseous exchange organs called ctenidial gills, reproduce sexually, feed on a wide variety of materials and live in most environments. Organism 4 is an Arthropoda. Arthropods have a body covered in chitinous cuticle that hardens into an exoskeleton, composed of somites (Metamerism), jointed appendages, ventral nerve cord with ganglia at each segment, open circulatory system and a bilateral symmetric body. Most Arthropods reproduce sexually; however some insects are parthenogenetic. Organism 4 was Porifera. Poriferans are commonly sponges which are sedentary by nature, most of them are marine sponges, cylindrical, have radial symmetry, have a body wall called a diploblastic, their middle layer has various wandering amoebocytes, have many ostia on their body, feed on minute organisms and small organic particles which enter the body through the oscula, have exoskeletons, secrete mainly ammonia, and asexual reproduction takes place by budding or sexual reproduction take place through internal fertilization. Organism 5 and 9 are Cnidaria. Cnidarian organisms are radially symmetrical, have bodies with internal cavity and a mouth, reproduction is sexual or asexual, has a simple net-like nervous system, has a distinct larval stage which planktonic, live in aquatic environments, mostly carnivores otherwise filter feeders, and have minimal skeleton of chiton or calcium carbonate. Organism 6 is echinodermata. These organisms free living, exclusively marine forms, larvae are bilaterally symmetrical while the adults are radially symmetrical, have bodies represented by a central disc covered by ossicles with spines called pedicularia, disc may bear extensions called arms, have a complete digestive system, have a water vascular system, posses tube feet for locomotion and respiration as well as feeding, has a central nervous sytem ring with five radiating nerves, sexual reproduction, development is indirect, and posses an ability to regenerate. For organism 3, the subphylum is Crustacea. Crustacea are primarily aquatic arthropods, but also include terrestrial forms, which have a cephalothorax covered by a carapace. They also have mandible mouthparts, gills for respiration, antennae, and biramous appendages.

Carpenter Ants, Genus Camponotus

Carpenter Ants, Genus Camponotus Carpenter ants are so named for their skill at constructing their homes from wood. These large ants are excavators, not wood feeders. Still, an established colony can do structural damage to your home if left unchecked, so its a good idea to learn to recognize carpenter ants when you see them. Carpenter ants belong to the genus Camponotus. Description Carpenter ants are among the largest ants that people encounter around their homes. Workers measure up to a 1/2 inch. The queen is slightly larger. In a single colony, you may find ants of varying sizes, however, as there are also smaller workers that reach just 1/4 inch in length. Color varies from species to species. The common black carpenter ant is, predictably, dark in color, while other types may be yellow or red. Carpenter ants have a single node between the thorax and abdomen. The top of the thorax appears arched when viewed from the side. A ring of hairs encircles the tip of the abdomen. In established colonies, two castes of sterile female workers develop – major and minor workers. The major workers, which are larger, defend the nest and forage for food. Minor workers tend to the young and maintain the nest. Most carpenter ants build their nests in dead or decaying trees or logs, though they do also inhabit landscape timbers and wooden structures, including peoples homes. They prefer moist or partially decayed wood, so carpenter ants in the home may suggest a water leak has occurred. Classification Kingdom - Animalia Phylum - Arthropoda Class - Insecta Order - Hymenoptera Family - Formicidae Genus - Camponotus Diet Carpenter ants do not eat wood. They are true omnivores and not all that picky about what they will consume. Carpenter ants will forage for honeydew, the sweet, sticky excrement left behind by aphids. Theyll also eat fruits, plant juices, other small insects and invertebrates, grease or fat, and anything sweet, like jelly or syrup. Life Cycle Carpenter ants undergo complete metamorphosis, in four stages from egg to adult. Winged males and females emerge from the nest to mate beginning in the spring. These reproductives, or swarmers, do not return to the nest after mating. Males die, and females establish a new colony. The mated female lays her fertilized eggs in a small wood cavity or in another protected location. Each female lays about 20 eggs, which take 3-4 weeks to hatch. The first larval brood is fed by the queen. She secretes a fluid from her mouth to nourish her young. Carpenter ant larvae look like white grubs and lack legs. In three weeks, the larvae pupate. It takes an additional three weeks for the adults to emerge from their silken cocoons. This first generation of workers forages for food, excavates and enlarges the nest, and tends to the young. The new colony will not produce swarmers for several years. Special Adaptations and Defenses Carpenter ants are largely nocturnal, with workers leaving the nest at night to forage for food. The workers use several cues to guide them to and from the nest. Hydrocarbons from the ants abdomens mark their travels with a scent to assist them in returning to the nest. Over time, these pheromone trails become major transportation pathways for the colony, and hundreds of ants will follow the same path to a food resource. Camponotus ants also use tactile trails to find their way back and forth. Ants feel and remember the distinct edges, grooves, and ridges in tree trunks or sidewalks as they move through their environment. They also employ visual cues along the way. At night, carpenter ants use moonlight to orient themselves. To appease their appetites for sweets, carpenter ants will herd aphids. Aphids feed on plant juices, then excrete a sugary solution called honeydew. Ants feed on energy-rich honeydew, and will sometimes carry aphids to new plants and milk them to get the sweet excretion. Range and Distribution Camponotus species number about 1,000 worldwide. In the U.S., there are approximately 25 species of carpenter ants. Most carpenter ants live in forest ecosystems.

At the end of the study, the project draws a conclusion on oil and gas companies and its response to the complex and urgent sustainability issues. This report will be a crucial one to understand the future energy supply-demand balance.The report is prepared on the basis of consumer view-point, the catastrophes’ caused and data analysis. Firstly, the project makes an analysis of the three companies holding the leading positions in the market. Following this the macroeconomic analysis has been provided which is a reflection of PESTEL. An analysis has also been done with regards to the present financial performance of the three companies. PESTEL demonstrates the political, economic, socio-cultural, technological, environmental and legal factors which influence the companies. Finally, an analysis of the internal strengths, weaknesses, threats and opportunities are some of the factors based on which the strategies have been recommended for the three companies. I ntroduction Oil and natural gas account for one of the major requirements in the daily lives of people. More than 60% of a nation’s energy is provided by natural gases and oil. ... Since 2005 February, the world supply of oil has been flat. There has been 1.4% increase in its production since December 2007 (Arup, â€Å"Introduction†). Firstly the project analyses the position of the three leading oil and natural companies namely, Shell, BP, Exxon-Mobil. Firstly the macroeconomic analysis is done using PESTEL and then based on this analysis the respective strengths, weaknesses, opportunities and threats are determined. The three companies are analysed with respect to their financial performance and how the present global scenario has impacted that performance. Following from the research it aims to make a comparative analysis of the positions of the three companies in the market. About the Companies Exxon Mobil operates in about 41 countries and is one of the renowned Energy and Technology sources, striving to meet the increasing demand.
