Einsteinium Facts - Element 99 or Es

Einsteinium Facts - Element 99 or Es   Einsteinium is a soft silver radioactive metal with atomic number 99 and element symbol Es. Its intense radioactivity makes it glow blue in the dark. The element is named in honor of Albert Einstein.   Discovery Einsteinium was first identified in the fallout from the first hydrogen bomb explosion in 1952, the Ivy Mike nuclear test. Albert Ghiorso and his team at the University of California at Berkeley, together with Los Alamos and Argonne National Laboratories, detected and later synthesized Es-252, which exhibits a characteristic alpha decay with an energy of 6.6 MeV. The American team jokingly named element 99 pandamonium because the Ivy Mike test had been codenamed Project Panda, but the name they officially proposed was einsteinium, with element symbol E. The IUPAC approved the name but went with the symbol Es. The American team competed with a Swedish team at the Nobel Institute for Physics in Stockholm for credit discovering elements 99 and 100 and naming them. The Ivy Mike test had been classified. The American team published results in 1954, with the test results declassified in 1955. The Swedish team published results in 1953 and 1954. Properties of Einsteinium Einsteinium is a synthetic element, probably not found naturally. Primordial einsteinium (from when the Earth formed), if it existed, would have decayed by now. Successive neutron capture events from uranium and thorium could theoretically produce natural einsteinium. At present, the element is only produced in nuclear reactors or from nuclear weapon tests. It is made by bombarding other actinides with neutrons. Although not a lot of element 99 has been made, it is the highest atomic number produced in sufficient quantities to be seen in its pure form. One problem studying einsteinium is that radioactivity of the element damages its crystal lattice. Another consideration is that einsteinium samples quickly become contaminated as the element decays into daughter nuclei. For example, Es-253 decays into Bk-249 and then Cf-249 at the rate of about 3% of the sample per day. Chemically, einsteinium behaves much like other actinides, which are essentially radioactive transition metals. Its a reactive element that exhibits multiple oxidation states and forms colored compounds. The most stable oxidation state is 3, which is pale pink in aqueous solution. The 2 phase has been shown in a solid state, making it the first divalent actinide. The 4 state is predicted for the vapor phase but has not been observed. In addition to glowing in the dark from radioactivity, the element releases heat on the order of 1000 watts per gram. The metal is noteworthy for being paramagnetic. All isotopes of einsteinium are radioactive. At least nineteen nuclides and three nuclear isomers are known. The isotopes range in atomic weight from 240 to 258. The most stable isotope is Es-252, which has a half-life of 471.7 days. Most isotopes decay within 30 minutes. One nuclear isomer of Es-254 has a half-life of 39.3 hours. The uses of einsteinium are limited by the small quantities available and how quickly its isotopes decay. It is used for scientific research to learn about the elements properties and to synthesize other superheavy elements. For example, in 1955 einsteinium was used to produce the first sample of the element mendelevium. Based on animal studies (rats), einsteinium is considered a toxic radioactive element. Over half of ingested Es is deposited in bones, where it remains for 50 years. A quarter goes to the lungs. A fraction of a percent goes to reproductive organs. About 10% is excreted.

Definition and Examples of Abstract Nouns in English

Definition and Examples of Abstract Nouns in English In English grammar, an abstract noun  is a  noun or noun phrase  that names an idea, event, quality or concept - for example, courage, freedom, progress, love, patience, excellence and friendship.  An abstract noun names something that cant be physically touched. Contrast that with a  concrete noun. According to A Comprehensive Grammar of the English Language, abstract nouns are typically non-observable and nonmeasurable.†Ã‚  But, as James Hurford explains, the distinction between abstract nouns and  other common nouns is relatively unimportant, as far as grammar is concerned. (James Hurford, Grammar: A Students Guide. Cambridge University Press, 1994) Examples and Observations Love is an irresistible desire to be irresistibly desired.(Robert Frost)Her face, which was long and dark chocolate brown, had a thin sheet of sadness over it, as light but as permanent as the viewing gauze on a coffin.(Maya Angelou, I Know Why the Caged Bird Sings. Random House, 1969)Creativity requires the courage to let go of certainties.(Erich Fromm)Silence can be  a source of great strength.Men say they love independence in a woman, but they dont waste a second demolishing it brick by brick.(Candice Bergen, quoted by Catherine Breslin in The Mistress Condition. Dutton, 1976)When love is gone, theres always justice.And when justice is gone, theres always force.And when force is gone, theres always Mom.Hi, Mom!(Laurie Anderson, O Superman. 1981)Fear is the main source of superstition, and one of the main sources of cruelty. To conquer fear is the beginning of wisdom.(Bertrand Russell, An Outline of Intellectual Rubbish. Unpopular Essays. Simon Schuster Inc., 1950) More than any other time in history, mankind faces a crossroads. One path leads to despair and utter hopelessness. The other, to total extinction. Let us pray we have the wisdom to choose correctly.(Woody Allen, My Speech to the Graduates. The New York Times, 1979) The Nature of Abstract Nouns Abstract and concrete are usually defined together or in terms of each other. The abstract is that which exists only in our minds, that which we cannot know through our senses. It includes qualities, relationships, conditions, ideas, theories, states of being, fields of inquiry and the like. We cannot know a quality such as consistency directly through our senses; we can only see or hear about people acting in ways that we come to label consistent. (William Vande Kopple, Clear and Coherent Prose. Scott Foresman Co., 1989) Countable and Uncountable Abstract Nouns Although abstract nouns tend to be uncountable (courage, happiness, news, tennis, training), many are countable (an hour, a joke, a quantity). Others can be both, often with shifts of meaning from general to particular (great kindness/many kindnesses).(Tom McArthur, Abstract and Concrete. The Oxford Companion to the English Language. Oxford University Press, 1992) Inflection of Abstract Nouns [M]any abstract nouns are generally not inflected for number (lucks, nauseas) or they do not occur in the possessive (the commitments time). (M. Lynne Murphy and Anu Koskela, Key Terms in Semantics. Continuum, 2010) The Grammatical Unimportance of Abstract Nouns [R]ecognizing abstract nouns is relatively unimportant, as far as grammar is concerned. This is because there are few, if any, particular grammatical properties that affect just the set of abstract nouns. ... One suspects that the reason for the recurrent mention of abstract nouns is the clash between their (abstract) meanings and the traditional definition of a noun as the name of a person, place or thing. The existence of obvious nouns such as liberty, action, sin and time is a sore embarrassment to such a definition, and the pragmatic response has been to apply a distinctive label to the problematic words. (James R. Hurford, Grammar: A Students Guide. Cambridge University Press, 1994) The Lighter Side of Abstract Nouns It represents Discipline, said Mr. Etherege. ... And to the uninstructed mind, Uniformity. His abstract nouns were audibly furnished with capital letters. But the latter notion is fallacious.No doubt, said Fen. He perceived that this incipient homily required punctuation rather than argument.Fallacious, Mr. Etherege proceeded, because the attempt to produce Uniformity inevitably accentuates  Eccentricity. It makes Eccentricity, as it were, safe. (Bruce Montgomery [aka Edmund Crispin], Love Lies Bleeding. Vintage, 1948)

Controls for Information Security Essay Example | Topics and Well Written Essays - 500 words

Controls for Information Security - Essay Example The combination of preventive, detective and corrective controls are suitable for the security of an organization’s information system because the multiple control layers work together to avoid a single point of failure. The detective controls comprise of log analysis, intrusion detection systems and constant monitoring of the system (Romney, et al, 2012). Similarly, the preventive mechanism identifies the probability of an attack and initiates control measures, such as IT solutions, physical security or change of controls and management. The preventive control functions towards identifying and blocking the malicious risk. It involves the observation of safe computing practices that hinder unwarranted access by others. After the prevention measures, the corrective controls ensure that the affected data can be restored to usefulness. Considering this, the combination or the detective, preventive and corrective controls work through the entire systems by recognizing threats both internally and externally. Controls must always be in place in an organizational system since they protect the deletion, copying or transfer of data. This implies that controls also serve as data security that may reach the hands of unauthorized parties. It is essential to install all the control strategies that function together towards achieving the organizational performance (Romney, et al, 2012). This is because it is easy to thwart fraud cases that might involve the fabrication of data to suit the cybercriminals.

Apparently there is huge shortage of licensed engineers as per... The aerospace industries which is at the forefront of wealth production worldwide, and continue to be of crucial importance to the economic strength of the UK rely on skills in a sound understanding of engineering and science areas relating to aircraft design and manufacture. Avionics institutions productions and outputs in terms of graduates in the field of engineering were surveyed by way of mailed questionnaires to gain the perspective on the prospects of manpower supply to satisfy the demand for avionics engineers. It was also geared towards awareness of the limiting factors confronting potential candidates for training. The study revealed that: all male composed the aircraft maintenance engineers' population; Most of the respondents were 36 - 40 years old (16 or 53.33 %) which is the highest value, and it is in close proximity to the retirement age; Majority of the respondents were married; Majority of the respondents were bachelor's degree holder only; The present numbers of master's degree holder and post graduate degree holder will increase in the near future; Minimal numbers of qualified aircraft maintenance engineers are in the UK airlines; The higher is the educational attainment of the respondents, the lower is their frequency; The respondents know that there is aircraft maintenance training in

Analyzing Talk Among Friends Essay Example for Free

Analyzing Talk Among Friends Essay In the preceding example, the utterance Ahma git me Ð ° gig! was interpreted differently by the participants in the interaction. So the question to be asked about Ahma git me Ð ° gig! is, what does it mean (how did the listeners arrive at their understandings), and what particular features of language and/or social situation signal that meaning? To arrive at an understanding of what the utterance meant, interpretations are not constructed solely from the speakers perspective but are also gathered from the participants who heard the utterance. Later, others may be asked to listen to Ð ° recording and share their understandings of the utterance(s). Then, the analysts task is to make an in-depth study of the selected instances of verbal interaction, observe whether or not actors understand each other, elicit participants interpretations of what goes on, and then (Ð °) deduce the social assumptions that speakers must have in order to act as they do, and (b) determine empirically how linguistic signs communicate in the interpretation process ( Gumperz 1982: 35). In the analysis of the example noted here, for instance, Gumperz was able to show that most white speakers did not seem to understand the utterance other than as Ð ° lapse into dialect or saw the switch to Black English as Ð ° rejection of whites and the speaker addressing himself only to other black students. Black students, however, explained the students remark as an attempt to justify himself by appealing to others in the group, Іm just playing the game as we blacks must do if we are to get along in Ð ° white world, while also identifying Ð ° particular rhythm in the utterance that led them to their interpretation. Thus, features of language carry social meaning that plays Ð ° significant role in interpreting what speakers mean (see Gumperz 1982: 29-37 for Ð ° detailed explanation of this example and its interpretation). While this example should make any interpreter wonder how they are interpreting meaning of speakers who differ in some way, such as region of the country, age, ethnicity, gender, my point here is about the analysis of natural language and how discourse analysts determine what speakers mean and how language conveys elements of meaning. Using these methods to analyze interpreted discourse is Ð ° way of understanding how the participants in an interpreted interaction understand each other at the time. Gumperz proposed that Ð ° theory of discourse must take into account both the linguistic and socio-cultural knowledge that an interlocutor must have to maintain involvement in an interaction, Accounting for such knowledge demonstrates two things: (1) meanings are jointly constructed between speakers as they talk, and (2) conversations contain internal evidence of their outcomes, that is, the ways in which participants share, partially share, or do not share, mutual conventions for meaning and how they succeed in achieving their communicative ends. Tannen reached Ð ° similar conclusion. She called such linguistic and social knowledge conventions by which meaning is communicated in social interaction (1984: 151). In Conversational Style: Analyzing Talk Among Friends, Tannen (1984) analyzed two and Ð ° half hours of conversation over Ð ° Thanksgiving dinner. She defined and discussed features of conversational involvement, such as topic, pacing (how relatively fast or slow one spoke), narrative strategies (in what order events are told, how speakers made their point, etc.), and expressive paralinguistic (intonation, pitch, and others), which together pattern in different ways the speech of different participants. For three of the speakers, these features combined in acceptable ways of having Ð ° conversation, but three other speakers experienced the same conversation as unusual and their participation faltered. When speakers share conventions for signaling meaning, they can be said to share Ð ° conversational style ( Tannen 1984). Tannens approach to studying discourse, modeled after Gumperz, is characterized by (1) recording naturally occurring conversations; (2) identifying segments in which communication may seem to flounder or be troublesome; (3) looking for patterned differences in signaling meaning that could account for trouble; (4) playing the recording, or segment of it, back to participants to elicit their spontaneous interpretations and reactions, and also, perhaps later, eliciting their responses to the researchers interpretations; and (5) playing segments of the interaction for other members of the cultural groups represented by the speakers to discern patterns of interpretation. Tannens study suggests that within an interpreted interaction speakers who do not share Ð ° common language also have conversational styles that they do not necessarily share with the interpreter. For example, Tannen (1994) has demonstrated that Ð ° discourse approach to gender and language, following in the tradition of Gumperz, can be understood by looking for differences in the way women and men signal meaning in conversation. This has great implications for interpreters: what happens when interpreter’s do not share Ð ° conversational style with one or both speakers? Many interpreters are women who interpret for men. Do they understand male strategies for asking questions or giving information? Do men understand female strategies? As her research demonstrates, the notion of cross-cultural encompasses more than just speakers of different languages or from different countries; it includes speakers from the same country of different class, region, age, and even gender ( Tannen 1985: 2o3). Gumperzs analysis of brief utterances located within Ð ° social scene and Tannens analysis of Ð ° single extended interaction via the same analytical and interpretive framework provide Ð ° rigorous methodology for analyzing conversational interactions, including interpreted conversations. Their emphasis on soliciting participant reactions and interpretations, along with close transcription of contextualization cues in language, provides Ð ° framework for going beyond Ð ° mere structural description of an interpreted encounter to an intense scrutiny of turn-taking as experienced by the participants, including phenomena such as simultaneous turn-taking.

The Victory of Banquo in Shakespeares Macbeth :: Free Essay Writer

The Victory of Banquo in Macbeth      Ã‚  Ã‚   The audience sees in Shakespeare's Macbeth that the one who ends up victorious, the one whose family will provide kings for the kingdom, is the innocent, spiritually inclined Banquo. It is he about whom this essay will deal.    In Shakespeare and Tragedy John Bayley discusses Banquo shortly before his murder:    [. . .] like Banquo, who, in the tense hour before the murder, expresses in more forceful form the idea of evil speculation and possibility as ranging in the mind:    Merciful powers, Restrain in me the cursed thoughts that nature Gives way to in repose. II.i.7-9    At such a moment the activities of the mind become almost palpable and express themselves in bodily form, as they do in the other two mind tragedies. In the speech which he imagines the thoughts that may come to him when he goes to rest, Banquo hands his sword to his son Fleance, and then - with a dream-like precision - hands over his belt with its dagger too:    Hold, take my sword. There's husbandry in heaven; Their candles are all out. Take thee that too. (188-89)    Lily B. Campbell in her volume of criticism, Shakespeare's Tragic Heroes: Slaves of Passion, discusses how fear enters the life of Banquo with the murder of Duncan and his two attendants:    And as Lady Macbeth is helped from the room, we see fear working in the others. Banquo admits that fears and scruples shake them all, even while he proclaims his enmity to treason. But Banquo fears rightly the anger or hatred of the Macbeth who has power to do him harm. (222)    Clark and Wright in their Introduction to The Complete Works of William Shakespeare comment that Banquo is a force of good in the play, set in opposition to Macbeth:    Banquo, the loyal soldier, praying for restraint against evil thoughts which enter his mind as they had entered Macbeth's, but which work no evil there, is set over against Macbeth, as virtue is set over against disloyalty.   (792)    In Fools of Time: Studies in Shakespearean Tragedy, Northrop Frye explains the rationale behind Banquo's ghost in this play:    Except for the episode of Hercules leaving Antony, where mysterious music is heard again, there is nothing really supernatural in Shakespeare's tragedies that is not connected with the murder of the order-figures.

Man is like a fraction

Man Is like a fraction whose numerator Is what he Is and whose denominator is what he thinks. The greater the denominator, the lesser the fraction. † -Lev Tolstoy We should take note that in a fraction, as the denominator becomes larger, the value of the traction becomes lesser. Man is also like a traction as what Lev Tolstoy said in his quotation. Life Is full of choices, full of situations. Where sometimes all our way to run away is by pretending, Pretending is one way of escaping. In my life, I have met people who are pretentious. I don't understand why they are like that.Why o people appear to be something theyre not? Does it make them feel better about themselves or does It make them have something to hide behind? People feel that if they can lead a life that isnt their own and be pulled along by someone else they may be able to achieve better things. Therefore, hiding behind masks makes people lives a lot easier, they don't have to face up to doing something wrong. The ap pearance of being greater than you are has led to many unfortunate happening in the world around us. Nevertheless it shows us how appearing to be something you're not, can become your reality and even the world's reality.We need to be less influenced by the world around us. Reality is hard to find as people are working their way around It, forcing themselves to appear to be something they're not. If we feel that we can get ahead by doing this then we should realize that we will only get hurt. Let us not be a person who sees himself larger than who he really is. Iva Rhiana C. Santiago LG 4218 APOLLONIUS OF PERGA As what I have researched, Apollonius ot Perga was a Greek geometer and astronomer noted for his writings in the conic section.

The work of Apollonius of Perga has had such a great impact on the development of mathematics, that he is kno wn as â€Å"The Great Geometer†.

HIS conlcs Tor me were easy to For me, teenagers or children nowadays should learn how to save money since young. Saving money helps to lessen the heavy responsibility of our parents as what I have observed. We can also buy th eir own items without asking money from our parents.Saving money also helps us to be more independent. Although I did not complete the required number of weeks I have to deposit, I think I was only able to deposit four times out of eight weeks, I am lucky to learn a lesson from this. I can benefit from saving money at young age. I realized that after high school, college is expensive and then â€Å"real† life begins, with expenses such as food and rent. If I can hold onto a good portion of the money I earned as a teen, going to college and buying a house will be much easier. The earlier I will begin saving, the more time the money has to grow.

Should companies treat their employees with respect and treat each one of them with dignity?

All companies should treat their employees with respect and treat each one of them with dignity. Every employee is an asset of a company and without them no company can function properly. Every person in this world has their rights that should be respected and not trampled upon. Employees are human beings with feelings and this should be instilled in the minds of all company owners or their managers or agents. No one is given the right to discriminate against people who are born with disabilities or who for some reason, has gone through a difficult experience in their lives which resulted to any physical deformity.People who, for some reason, have any special characteristic should not be discriminated against. When a person applies for a job, the potential employer should look beyond the physical appearance of any person with disability. He should instead look objectively and analyze whether that person has the skill or capability to perform the required task. The potential employer should thoroughly evaluate the employee to see whether or not, despite his apparent weakness, he is still able to deliver or perform the job just like any normal person.Once the person with disability gets hired, he should be treated fairly by the employer. The employer should provide for some facilities to accommodate the employee. An example of which is when the employee is handicapped, the employer should provide a passage for the employee like a ramp or elevator for easy access to the employee. The employer should also provide for a comfort room which is to be used by handicapped people which should be larger than the normal cubicle to enable them to move freely with their wheelchair.The employer may also provide a work friendly environment to handicapped employees by providing them with a special chair or a comfortable work area where the employee can move around without his freedom being restricted. Employees who suffer from a drug abuse problem may still find a job that would enable them to overcome their drug dependence. If the employee is otherwise qualified by the job, the employer may overlook this drug addiction, and instead find ways to help the latter move on from such weakness.The employer may provide for an environment that would foster camaraderie, training, workshops, seminars and the like to distract the employee’s attention from drug dependence and to shift his focus. This would serve as a distraction for the employee who would soon get healed from his dependency. The simulation may demonstrate this scenario by creating a situation which involves an employer hiring an employee who is handicapped. Both parties may work out a case wherein the employee would try to internalize his role and look at the possible office situations which would help them improve their relationship and to better his work performance.The factors of personality, attitude toward work, and future upward mobility may play a big or little role in a potential workin g environment depending on the kind of workplace or job the employee is applying for. Personality is very important when the job description calls for the characteristic of being sociable as in a marketing job. But, personality may be of little importance to a person employed in a work place where there is no face to face interaction with a client or customer. An employee is the representative of the company, whether such employee is an officer, manager or staff.It would be advantageous for any company to have employees who are outgoing and sociable, however this would only apply for those jobs whose employees are required to be on the frontline. Thus, as to this factor of personality, it would really depend on what the company is for it to be considered as an important criterion for hiring. As to the attitude toward work, I am of the opinion that this is important and should be considered when hiring an employee. The attitude of a person towards his work would reflect a great deal about his personality.The person should show that he loves his work and would take it seriously, otherwise, the company might be in the losing end and suffer in the long run. The employer should weigh the scenario, for example, when there are two applicants for a job, one without any disability but his attitude towards his work is such that he merely views it as a means to an end and another who has some disabilities but whose attitude towards work is such that he views it with enthusiasm, with zeal and with passion, then the employer should hire the second applicant.A person who shows a positive attitude towards his work would help fuel the company to success and great heights. The factor of future upward mobility would have to be qualifies. For example, a work which would require physical strength such as construction, carrying of heavy baggage, running around or other strenuous physical activities, would necessarily require an employee who would be able to perform the job, thus s hould be mobile. However, a work which requires analysis or computer work and is which would not entail any physical mobility would not need an employee who is equipped with upward mobility.An employee should be hired based on his skills and qualifications and not based on his personal appearance. The simulation would be able to demonstrate the importance of those factors by creating an environment that would consider the job description and co-relate these with the applicants. Each scenario should be viewed differently by considering the different needs of each job and determine the applicable skill required for a potential employee. The employer should be able to decide whether or not a certain factor is needed for the delivery of the desired result.Title VII can override the employment contract between an employer and employee. It is the rule that contracts between parties should not be contrary to any existing law. Title VII of the Civil Rights Act of 1964 provides in essence th at no person should be discriminated against on the basis of race, color, sex, religion, or national origin. In general, there should be equal work opportunity for every person regardless of any disability or otherwise. A person who has some disability should be hired if he is qualified for the job.Further, once he is hired he should receive the same amount of pay and benefits as any normal employee since the employer should look beyond the disability and give equal work opportunities to both of them. There should be no diminution of salary or benefits for the reason that the employee has some disability. An employee should not compromise his rights for the reason that he is in desperate need of a job and the employer should not use his bargaining power as a person who is in authority of giving the job.An agreement which provides for benefits, wages or others that are below the minimum wage or contrary to any law is null and void and is of no force and effect. The law is above any w ritten contract since the former must always be in consonance with the latter. The simulation would demonstrate this by portraying a situation which depicts an environment where the employer and the employee would agree on terms that are for the advantage and benefit of both but is not contrary to law.

A Mistake That Taught You an Important Lesson Essay Example

A Mistake That Taught You an Important Lesson Essay Example A Mistake That Taught You an Important Lesson Essay A Mistake That Taught You an Important Lesson Essay Chapter 1: Basic concepts and terms This chapter answers the following questions: What is a dictionary? What are the different types of dictionaries? How can we describe a dictionary? What are the elements of a dictionary? What are the different kinds of information dictionaries provide? What is a dictionary? This is the first question one encounters when learning about dictionary skills or reading any book on lexicography (the art of compiling dictionaries). Defining the term dictionary is important to distinguish it from other reference books, which may look similar, like encyclopedias. Etymologically, the word dictionary comes from the Middle Latin word dictionarium, which means collection of words and phrases. This definition relates to the basic function of dictionaries which is listing the words of a language or a particular field of knowledge. This simple fact is the basis of all the definitions proposed for a dictionary. A dictionary is a book used as a reference source which contains lists of words arranged alphabetically or thematically, with explanations of their meanings (semantic information in monolingual dictionaries) or with their equivalents (in bi-, tri-, or multilingual dictionaries). They may also include more information related to orthography (spelling, alternate spellings), morphology (syllabification, word inflections, derivative forms, morphological paradigm), phonology (pronunciation, stress pattern), etymology (word history and origin), syntax (part of speech, verb type, noun type, etc), pragmatics (usage, frequency of use, style, context), and other semantic information (related words such as synonyms, antonyms). A dictionary may variously be referred to as: word book, lexicon, thesaurus, vocabulary, glossary, and concordance. However, each one of these is slightly different in scope. For example, a thesaurus (also from Latin, and which means a treasury or a storehouse) presents synonyms and antonyms; a glossary usually gives a list of terms confined to a particular domain of knowledge with definitions. What distinguishes a dictionary from these different types is that none of them provides all the different kinds of linguistic information a dictionary provides. Use thesaurus in a Sentence See images of thesaurus Search thesaurus on the Web Types of dictionaries: Dictionaries vary in coverage, size, and scope. They can be classified on the basis of different criteria. Knowing the types of dictionaries available is very important to decide which ones to buy or use. The following criteria are used to classify dictionaries: 1) Number of languages: Monolingual dictionaries are written in one language only. Each word is followed by its meaning or various meanings and probably other information related to pronunciation, grammar, or word history. Bilingual dictionaries are written in two languages. Each word is followed by its equivalent or possible equivalents in another language. Bilingual dictionaries could be uni- or mono-directional; that is, they go in one direction only, from English to Arabic or vise versa. They could also be bidirectional; that is, the dictionary is divided into two parts; the first part is from Language 1 to Language 2, and the second one is from Language 2 to Language 1. Trilingual dictionaries are written in three languages. Multilingual language are written in more than two languages. 2) Age of the users: School dictionaries are intended for school students and they are graded according to childrens age: elementary, middle, and high school students. They are simplified versions of adult references. They may also be referred to as childrens dictionaries if they are intended for very young children. Adult dictionaries, on the other hand, are intended for adults and these are the ones that translators use and they include a variety of dictionary types such as college dictionaries, current language dictionaries, and unabridged dictionaries. 3) Size of the dictionary: This has to do with how fully a dictionary covers the lexicon of a particular language. The number of words is a measure of its relative size compared with other dictionaries in the same language. According to this criteria, dictionaries can be classified into the following. a) Unabridged dictionaries which are believed to include all the words of the English language (400,000 to 600,000 words). They give full coverage to the lexicon in general use and to specialized lexicon, with examples and all other information any dictionary could give. In other words, they provide complete and authoritative linguistic information. They are impractical for desk use because of their size and expense, but they are available in libraries and are important reference sources. Examples: Websters Third New International Dictionary (NID3), and Oxford English dictionary (OED) which has 20 volumes. Semis: The American Heritage Dictionary of the English Language, The Random House College Dictionary, Websters New World Dictionary of American English. They are called college dictionaries because they are often used by college students. c) Desk dictionaries include from 60,000 to 100,000 words. Examples: The American heritage dictionary, Merriam-Websters Collegiate Dictionary. They are called desk dictionaries because they are often kept on desks for frequent reference. College and desk dictionaries are often abridged versions of larger dictionaries. Some publishing houses use the term college to refer to both college dictionaries and desk dictionaries. Some other houses use the term concise to refer to desk dictionaries; e. g. Concise Oxford Dictionary, Longman Concise English Dictionary. d) Pocket size dictionaries, which include from 40,000 to 60,000 words; e. g. Pocket Oxford Dictionary. 4) Scope of coverage by subject: Subject-field dictionaries are confined to a special subject, such as law or medicine. Special-purpose dictionaries are limited to one aspect of language: collocations, slang, pronunciation, etymology, synonyms, usage, offensive and taboo words, spelling, dialect, neologisms, etc. A functional classification of dictionaries: For the purpose of the present course, which ultimately aims at training students to use dictionaries as professional translators, we will adopt the following classification that is based on the functions of dictionaries. Dictionaries are divided into two types: traditional and electronic dictionaries. I. Traditional (or regular) dictionaries: Traditional dictionaries are printed dictionaries (paper /print dictionaries). They are divided into four main categories: linguistic, visual, picture, and encyclopedic dictionaries. 1) Linguistic dictionaries are dictionaries that are concerned with words and provide linguistic information and may contain some pictures or illustrations. They are further divided into four types: general, learner, children, and specialized dictionaries. a) General-purpose dictionaries deal with the common words of a language and are compiled by language experts. They may be mono- or bilingual. They may be explanatory and help readers to understand a word meaning, its pronunciation, spelling, usage, etc. They may be translation dictionaries providing word equivalents. Explanatory and translation dictionaries may be unabridged, college, desk, concise, or pocket dictionaries. General-purpose dictionaries could also be production dictionaries (alternatively called activators) which are very useful in writing; they guide you as to which words or expressions to use to express similar or different ideas. They focus on use or meaning in context and on oral usage, rather than explaining their meanings. The first production dictionary is: Longman Language Activator: The Worlds First Production Dictionary (1993), Longman Essential Activator (intermediate level). The lexical information is organized around approximately 1000 key terms that serve as focal points for crucial sets of concepts. b) Learners dictionaries are aimed at students learning a language. Examples: Oxford Advanced Learners Dictionary, Collins Cobuild English Dictionary, Macmillan English Dictionary for Advanced Learners. c) Children dictionaries are very simplified versions specifically written for children. ) Specialized dictionaries are divided into two types: subject field dictionaries and special purpose dictionaries. Subject field dictionaries are limited to the vocabulary of specific scholarly areas or fields of knowledge such as medicine, law, religion, business and commerce, literature, military affairs and politics, etc. The rapid growth and development, and specifications in all the fields of knowledge has resulted in generating of new words or specialized terms for which the general dictionaries do not provide adequate information. Therefore, it became necessary to compile subject dictionaries which are devoted completely to specific subject fields. As a result many subject dictionaries and glossaries in Humanities, Social Sciences and Science ; Technology are coming out day-by-day. They are compiled by the experts in the different subject fields. Special purpose dictionaries deal with different aspects of language such as collocations, slang, idioms, phrasal verbs, neologisms, abbreviations, language varieties and dialects, synonyms and antonyms, pronunciation, etymology, usage, grammar, word frequencies, etc. ) Visual dictionaries tend to be complete dictionaries and rely on illustrations and photos or pictures; e. g. Merriam-Websters Visual Dictionary Online. 3) Picture dictionaries are often organized by topic instead of being an alphabetic list of words. They include only a small corpus of words because they are often intended for children. They may be mono-, bi-, or multilingual. 4) Encyclopedic dictionar ies has encyclopedic features; their concern is not the words of a language but rather with facts about things, objects, or people; e. . The Hutchinson Concise Encyclopedic Dictionary. II. Electronic dictionaries: An electronic dictionary is an electronic reference resource that contains a library of words and their meanings, spellings, and etymologies. They can be 1) portable (or handheld), battery-operated devices; 2) dictionary programs (on CDs) , or software running on PDAs or computers and which allow words or phrases to be input and translated; or 3) web based dictionaries accessible via the internet. Electronic dictionaries are more convenient than paper dictionaries and much faster to search. Examples of some online dictionaries: AskOxford Compact Oxford English Dictionary of Current English, Cambridge Dictionaries Online Cambridge Advanced Learners Dictionary, Dictionary. com Dictionary. com Unabridged v. 1. 1 and American Heritage Dictionary of the English Language, Fourth Ed, Longman Longman Dictionary of Contemporary English, Merriam-Webster OnLine Merriam-Webster Online Dictionary, Oxford University Press Oxford Advanced Learners Dictionary Dictionaries Traditional Dictionaries Electronic Dictionaries Portable devices CDs Online dictionaries Linguistic Visual Picture Encyclopedic General Learners Children Specialized Explanatory Production (Activators) Mono, college, desk, concise, pocket Explanatory Production Translation Explanatory Translation (monolingual) (bilingual) unabridged college or pocket college or desk Terminology (religious, literary, political, scientific, medical, etc) (mono and bi) concise Collocation, slang, idioms, phrasal verbs, common errors, neologisms, abbreviations (mono) pocket Synonyms, antonyms, thesaurus, production dic or activators (mono) Pronunciation, etymologies, usage, grammar, word frequencies, (mono) College, concise, pocket monolingual college or pocket Exercise: Find the following words in your dictionary, if you cant find them think of a reason to explain that: car cumdump goo gonzo coasthenia (psy) to smell to high heaven abarticulation (med) howitzer gun (mil) schlub action agent (mil) What type should you buy or use? Dictionaries are used by native speakers, language learners, or translators. Native speakers use dictionaries to help them in writing or in understanding unfamiliar words or phrases. For this purpose they use adult (unabridged or college) monolingual dictionaries. Language learners need learners monolingual dictionaries, whether elementary, intermediate, or advanced dictionaries depending on their level of language proficiency. Translators, on the other hand, need both mono- and bilingual dictionaries. They are advised to choose the most recent editions of college or unabridged dictionaries, as the other types of dictionaries are limited in their vocabulary coverage. They are also advised to have different types of specialized dictionaries of: idioms, collocations, phrasal verbs, usage, specialized terminology (religious, legal, political, medical, literary, military, psychological, scientific, etc). Elements of dictionaries: The elements of any dictionary can be discussed in terms of two levels: the macrostructure and microstructure. The macrostructure is concerned with dictionary features such as the front matter, the end or back matter, entry organization. The microstructure is limited to the structure of entries and the kinds of information they provide. We will discuss these two levels in detail in the following chapter on general monolingual dictionaries.

Brief History of Cod Fishing

Brief History of Cod Fishing The cods importance to American history is undeniable. It was cod that attracted Europeans to North America for short-term fishing trips and eventually enticed them to stay. The cod became one of the most sought-after fish in the North Atlantic, and it was its popularity that caused its enormous decline and the precarious situation today. Native Americans Long before Europeans arrived and discovered America, Native Americans fished along its shores, using hooks they made from bones and nets made from natural fibers. Cod bones such as otoliths (an ear bone) are plentiful in Native American middens, indicating they were an important part of the Native American diet. Earliest Europeans The Vikings and Basques were some of the first Europeans to travel to the coast of North America and harvest and cure cod. Cod was dried until it was hard, or cured using salt so that it was preserved for a long period of time. Eventually, explorers such as Columbus and Cabot discovered the New World. Descriptions of the fish indicate that cod were as big as men, and some say that fishermen could scoop the fish out of the sea in baskets. Europeans concentrated their cod fishing efforts in Iceland for awhile, but as conflicts grew, they began fishing along the coast of Newfoundland and what is now New England. Pilgrims and Cod In the early 1600s, John Smith charted out New England. When determining where to flee, the Pilgrims studied Smiths map and were intrigued by the label Cape Cod. They were determined to profit from fishing, although according to Mark Kurlansky, in his book Cod: a Biography of the Fish That Changed the World, they knew nothing about fishing, (p. 68) and while the Pilgrims were starving in 1621, there were British ships filling their holds with fish off the New England coast. Believing they would receive blessings if they took pity on the Pilgrims and assisted them, the local Native Americans showed them how to catch cod and use the parts not eaten as fertilizer. They also introduced the Pilgrims to quahogs, steamers, and lobster, which they eventually ate in desperation. Negotiations with the Native Americans led to our modern-day celebration of Thanksgiving, which would not have occurred if the Pilgrims did not sustain their stomachs and farms with cod. The Pilgrims eventually established fishing stations in Gloucester, Salem, Dorchester, and Marblehead, Massachusetts, and Penobscot Bay, in what is now Maine. Cod was caught using handlines, with larger vessels sailing out to fishing grounds and then sending two men in dories to drop a line in the water. When a cod was caught, it was pulled up by hand. Triangle Trade Fish were cured by drying and salting and marketed in Europe. Then a triangle trade developed that linked  cod to slavery and rum. High-quality cod was sold in Europe, with the colonists purchased European wine, fruit and other products. Then traders then went to the Caribbean, where they sold a low-end cod product called West India cure to feed the burgeoning slave population, and bought sugar, molasses (used to make rum in the colonies), cotton, tobacco, and salt. Eventually, New Englanders also transported slaves to the Caribbean. Cod fishing continued and made the colonies prosperous. Modernization of Fishing In the 1920s-1930s, more sophisticated and effective methods, such as gillnets and draggers were used. Commercial cod catches increased throughout the 1950s. Fish processing techniques also expanded. Freezing techniques and filleting machinery eventually led to the development of fish sticks, marketed as a healthy convenience food. Factory ships started catching fish and freezing it out at sea. Fishing Collapse Technology improved and fishing grounds became more competitive. In the U.S., the Magnuson Act of 1976 prohibited foreign fisheries from entering the exclusive economic zone (EEZ) - 200 miles around the U.S. With the absence of foreign fleets, the optimistic U.S. fleet expanded, causing a greater decline in fisheries. Today, New England cod fishermen face strict regulations on their catch. Cod Today The commercial cod catch has decreased greatly since the 1990s due to strict regulations on cod fishing. This has led to an increase in cod populations. According to NMFS, cod stocks on Georges Bank and the Gulf of Maine are rebuilding to target levels, and the Gulf of Maine stock is no longer considered overfished. Still, the cod you eat in seafood restaurants may no longer be Atlantic cod, and fishsticks are now more commonly made of other fish such as pollock. Sources CC Today. 2008.

Scientific Paper Report - Essay Example The main effect, in this case, is climate change and global warming. This paper explores climate change with the focus on explaining some of the causes of climate change alongside the recent changes in climate recorded on the surface of the earth. The term climate change can sometimes be used to refer to the climatic changes that are brought about due to human activities, rather than those climatic changes that are brought about as part of the natural processes of the earth. These terms have become quite relevance as far as the environmental policy, and the global warming anthropogenic are concerned. Global warming, in this case, represents the increases in temperature and climate change and deals with global warming, and other aspects including the levels of greenhouse effect. Arguably, the rate in which energy is received from the sun and the loosing rate to the space determine a great deal both the climate of the earth and the equilibrium temperature. As research would have it, th e energy is transferred all over the globe by use of ocean current, winds, and other different mechanisms which may affect the climate of other regions. It is worth noting that there are a number of factors that may lead to climate change. Key among them includes solar radiation, variation, and orbit of the earth, continental drift and the green house gas changes concentration. Different climatic alterations in climatic feedbacks can either diminish or amplify the forces that initially. Other parts of the system of climate such as ice caps, ocean. Within the climate variation context, human factors that are deemed to be affecting the climate are the anthropogenic factors. According to the scientific consensus concerning climate change, climate is always changing and the changes are largely due to human activities. Clearly, humans play an important role in so far as climatic alterations are concerned. Industrial revolution that took place in the 19th century brought about a large sca le use of the fossil fuels for purposes of industrial activities. Evidently, these many industries created many jobs causing people to migrate from their rural areas to cities and the trend has been sustained till present. Following this much of the land under vegetation have been clearly to pave way for houses. Natural resources, on the other hand, have been explored for purposes of constructing transport and industries. Consumerism has gone up by bound and leaps, thereby, creating mountains of waste. Moreover, the shooting up of the population has brought about incredible effects on the climate. All these factors have immensely contributed to the increase in the atmospheric greenhouse gases. Fossil fuels including coal, natural gas, and oil are the main sources of the energy for running vehicles, generation of electricity for industrial purposes, households and many more. Clearly, the sector of energy contributes on average three quarter of the carbon dioxide emissions, large quan tities of the nitrous oxide gas, and about a fifth of the methane emissions. Additionally, the energy sector, produce both carbon monoxide and nitrogen oxides gases, though not part of the greenhouse gases, have a significant influence upon the chemical cycles within the atmosphere producing or destroying greenhouse gases. The most concern of these human factors is the increase in t

EVALUATION OF RESOURES - Essay Example Considering the potential impact of ICT in the learning activities of the students, educational researchers have been consistently studying how ICT can be used as a pedagogical tool in improving the learning ability of the students. (Pearson, 2003; National Research Council, 2000) For this study, the researcher will determine the contribution of the following learning resources: digital cameras, Alphasmart key guard, Microsoft PowerPoint presentation and Microsoft Word towards the learning activities of the mainstream and special educational needs (SEN) students by conducting a short literature review. Prior to the conclusion, the researcher will conduct a quantitative and qualitative survey analysis in order to evaluate the impact of these learning resources with the Science learning activities of mainstream and SEN students. In relation to the learning activities of mainstream and SEN students, technology can be used as a teaching and learning tool that enables the school teachers and students to become co-learners by collaboratively constructing knowledge. (Reed & McNergney, 2000) For instance, the use of digital cameras enable the school teachers and students to record educational trip or a specific learning experience to enable both parties to review the learning process on a later date. In line with this matter, technology behind digital cameras make it possible for school teachers and students to experience a real-world examples of ‘learning by doing.’ Depending on the learning ability of these students, students could easily make a school report by recording certain learning events using the digital camera for the purpose of a group or individual class presentation. (Wellington & Wellington, 2002) In the process of being able to make a class presentation using digitalized visual materials, the students will be able to build self-confidence with their work since these materials could enable them to capture
