What Is an Electron Cloud

An electron cloud is ​the  region of negative charge surrounding an atomic nucleus that is associated with an atomic orbital. It is defined mathematically, describing a region with a high probability of containing electrons. The phrase electron cloud first came into use around 1925, when Erwin Schrà ¶dinger and Werner Heisenberg were seeking for a way to describe the uncertainty of the position of electrons in an atom. Electron Cloud Model The electron cloud model differs from the more simplistic Bohr model, in which electrons orbit the nucleus in much the same way as planets orbit the sun. In the cloud model, there are regions where an electron may likely be found, but its theoretically possible for it to be located anywhere, including inside the nucleus. Chemists use the electron cloud model to map out the atomic orbitals for electrons; these probability maps are not all spherical. Their shapes help predict the trends seen in the periodic table.

Language Is A Common Mistake - 1745 Words

There is a common mistake that individuals make when discussing if someone has learned a language or not. Most people believe that learning a language is about speaking, but it is also about understanding and comprehending language itself as well. For humans, majority talk about when their child first starts to speak as the moment they accredit them with learning the language. In actuality, the learning starts well before that. The research suggests that language is a complex system that starts with language distinguishing at only hours old and progresses to using semantics effectively at about 2 years old. These early years are a sensitive period in the child’s life, where the capacity to learn language is at its all time high. To properly illustrate this process, we must go in chronological order starting from before the child even emerges into the world. I have found that a human’s first concept of language is acquired in the womb, about 10 weeks prior to the child’s birth (McElroy, 2013). A study by the National Institutes of Health and Pacific Lutheran University’s S. Erving Severtson Forest Foundation Undergraduate Research Program proves this theory. The theory is based upon the hypothesis that infant’s, only hours old, are able to distinguish between their native and foreign languages (McElroy, 2013). The thought of language beginning to being learned in the womb is not that outrageous given that at thirty weeks of pregnancy the fetus develops sensory and brainShow MoreRelatedKey Features of AL and CLT Approach1363 Words   |  5 PagesAudio-lingual approach Communicative teaching language approach Approach Nature of language -structural view -Language: a system of structural phonological, grammatical and lexical patterns to express the functional meanings -functional view -Language: a medium for social interaction and communication Nature of language learning Behaviorism – Habit formation via over-learning Learners’ engagement in authentic and meaningful task to promote language learning.

The Dark Knight Review First Draft Essay Example

The Dark Knight Review First Draft Essay What comes to mind when you hear the word Batman? A dark figure looming in Gothams alleys? Adam West and Burt Ward Whamming and Powing their enemies? Or possibly one of the greatest films of the decade? Its fair to say that since the 70s,the original comic character Batman has changed( maybe develop this point), reincarnated with many different looks, and the outcome in my opinion is too camp or too dark. In his latest film, the director Christopher Nolan, seems to have the balance just right in The Dark Knight.( try to vary the opening of sentences) The film starts as a heist movie, a bank raid masterminded by the Joker (Heath Ledger), which is apposite as Heath Ledger steals every scene that hes in. Christian Bale also does a great performance (can you improve expression here)as Batman/ Bruce Wayne. However it seems that one of the reasons for Heath Ledger being hailed as the star is the contrast between the Joker and Batman that he brings to the role. Batman is very dark and serious (some might say, boring) and in a way that makes him boring; the Joker however is just insane, with his purple suit and constantly changing stories about how he got his scars. (Amoral and psychopathic , he explains ) and he evens mentions in the film how he will just commit homicide for no reason at all and that he just does things. He is, in terms of the 9/11 analogy, not just a terrorist but worse, an anarchist who just kills and destroys for fun. He is very creepy and completely mesmerising.

There is a (The clichà ¯Ã‚ ¿Ã‚ ½d love triangleis guaranteed to win approval from sections of the audience) love triangle in the film between Batman, Rachel (Maggie Gyllenhall) and Harvey Dent. Rachel is Bruces oldest friend and she knows that he is Batman, but she feels that Gotham will always need Batman and so that is why she chooses Harvey over Bruce. (comment on her moral stance. Is it convincing?) Gary Oldman (stars in the film) delete? as Jim Gordon, head of Gotham police department, clashes with Harvey Dent as they both have different ways of handling criminals. Jim Gordon is literally law and Harvey Dent is literally Order. The Dark Knight is a Batman morality tale turned up to 11- exploring the nature and corruption of power, the organization of society in crisis, individual freedom versus collective security, and (most interestingly of all), its allusions to the Roman Empire. If Harvey Dent is a Caesar figure, then the Joker is Caligula. ( The semi-colon is not used to introduce a list. It allows you to add a new sentence related to your first without separation by a full stop.) Morgan Freeman and Michael Caine are also in the film (it really is a star studded cast), Michael Caine plays Alfred Bruces Butler, best friend and assistant. ( The inclusion of Michael Caine alongside Morgan Freeman in this star studded cast allows Hollywood to emphasise Alfreds Englishness. One of the greatest British actors of the last thirty years, his iconic London accent will surely intrigue an American audience)It seems that Hollywood really wanted to emphasize that Alfred was English and so they chose one of the greatest actors of all time with a very thick London accent, (in case youre wondering Danny Dyer was not second choice for the role), he is probably the best Alfred compared to other actors who have taken on the role before.(if this is your opinion then be more assertive. Reviewers generally are.) Morgan Freeman plays (as)Lucius (avoid repetition of verbs like plays)Fox the man who essentially runs Wayne Enterprises and is one of Bruces many friends; he also has the v ery exciting job that all boys dream of being (doing/achieving) when they are grown up: the creator of Batmans gadgets and weapons. The film explores many themes: batman represents hope; he is incorruptible. Harvey Dent symbolises fate or chance.; Rachel symbolises love as all the males fall for her and loyalty is .. The film (explores)(has) many themes( in it) and it is almost as if with each character representing represents on of those themes, Batman for hope, as he is incorruptible; Harvey Dent for chance, as he carries around a coin with him to help him make decisions; Rachel for love as it seems Batman, Harvey Dent and even the Joker have all taken a fall for her; Alfred stands for loyalty as he has served Bruce Wayne since he was a child and raised him when his parents were dead; the world would be a much better place if everyone were like Alfred! The special effects in the film are very impressive. One of the more breath taking examples is Two Face who is half man, half burns. Half of his face is that of Harvey Dent, the other half is severe burns. This signifies goes with the 50:50, chance, toss a coin theme of Harvey Dent; in fact Two Face uses the same coin to decide whether to kill someone or not. There is also a contrast made between Harvey Dent and Batman as they are both fighting the same enemy, Harvey Dent does this in court and Batman does this in the streets. However Batman is less a person, more an idea of the upholding of the law. ( This used to be fine but) delete? Christopher Nolan suggests that the citizens are restless and the heroes need to come from within society not those conspicuously outside it, (9/11 heroes were the firemen and police officers of New York), and in fact the film is full of images that mirror the havoc after 9/11. One other contrast made in the film is that between the Joker and Batman; at first you may think that they are total opposites but then you find that actually they are both similar. They are outcasts, freaks as the Joker says (in the film) to Batman When they dont need you any more theyll hunt you down. In addition Bruce Wayne and Batman are total opposites; Batman is a vigilante who dedicates his life to fighting for good, and Bruce Wayne on the other hand is a wooden, envious, charisma free pompous businessman. The Dark Knight is more of a hero movie than a superhero movie, as in it is far more realistic; Batman cant fly or shoot web out of his hands but he can make things explode! But this isnt just (can you improve expression here) with the Dark Knight. Batman has always been an outcast to over ? superheroes as there is in fact nothing super about him; he is just up to his neck in gadgets. If all the superheroes went to school together Batman would be the one sitting alone at lunch, while Spiderman and Superman sat at the table with the popular kids. Also other films released recently have had a big (significant) effect on how it was directed, for example the action in Bourne films are (is) very similar to the action in the Dark Knight,( but it is not a bad thing.. can you improve expression here) it is not uncommon to hear a gasp while you are watching the scene where a Juggernaut does a front flip or where a whole building is blown up. The question of individual freedom versus collective security (a question thrown up by 9/11) is brought into case, when BatmanBruce Wayne invents a device which can monitor everyone in the city using their phones. It was created with the intent of finding the Joker and stopping him from claiming anymore lives; the only person who can operate it however is Lucius Fox, who feels that there is something morally wrong with it. He chooses to use it only once and then he makes Batman promise to destroy it; he agrees. This is also (reminiscent of ancient Rome)similar to the Caesar idea. When the enemies were at their gates, the Romans would choose one man to have power over them so that they could defeat their enemies; they had to give up freedom and democracy to survive and when the battle was won that one man would go back to his previous position. However the last man that the Romans chose used the power they had given him to rule over them. His name was Caesar. This was what Lucius was worried would happen to Batman if he kept that device. A phrase, which is often used in the film, is You either die a hero or live long enough to see yourself become the villain. In fifty years time, there will have been countless incarnations of Batman. Some will be good some will be bad, some will feature Robin, some without him; well see familiar faces of villains and well also see some new evildoers. But one thing is certain! (about these films. delete?) None will be as good as The Dark Knight.

Free Essays on Role Of Parents And Family In Children’s Drug Use

Over the past two decades, studies have shown that the influence of parents and family is a significant factor in children’s drug use. A large body of research findings shows that the family contributes both risk and protective factors to the lives of adolescents. It affects both vulnerability and resilience to drug abuse (NIDA Notes, May/June 1996). A series of studies confirm the role of parents and families in adolescents’ life choices, in which the objective was to identify risk and protective factors at the family, school, and individual levels as they relate to four domains of adolescent health and morbidity: emotional health, violence, substance use and sexuality (Resnick, 1997). Resnick studied over 12,000 adolescents, grades 7 through 12, and interviewed them one by one at home on varies problems mentioned above including substance use. The key finding is that being connected with their parents and families, sometimes with helps from school and peers, those tee ns are more successful in dealing with the existing or the potential substance abuse problems. He concludes that across all domains of risk, the role of parents and family in substance control is critical. Although the physical presence of a parent in the home at crucial time helps to reduce the risk of substance use, the more significant influencing factor is the parental connectedness. Other factors might include home settings and the frequent exposure to healthy environment. Homes that provide easy access to alcohol, tobacco, and other illegal substances increase the adolescents’ chances of being engaged in the activities which involved unhealthy substance using. This literature review explore several areas influencing adolescents’ substance use such as usage by parents, communication patterns of family patterns of family members, relationships to family member (attachment and connectedness), and the influences of family structure and the extended family.

Understanding The Bretton Woods System

Understanding The Bretton Woods System Nations attempted to revive the gold standard following World War I, but it collapsed entirely during the Great Depression of the 1930s. Some economists said adherence to the gold standard had prevented monetary authorities from expanding the money supply rapidly enough to revive economic activity. In any event, representatives of most of the worlds leading nations met at Bretton Woods, New Hampshire, in 1944 to create a new international monetary system. Because the United States at the time accounted for over half of the worlds manufacturing capacity and held most of the worlds gold, the leaders decided to tie world currencies to the dollar, which, in turn, they agreed should be convertible into gold at $35 per ounce.​ Under the Bretton Woods system, central banks of countries other than the United States were given the task of maintaining fixed exchange rates between their currencies and the dollar. They did this by intervening in foreign exchange markets. If a countrys currency was too high relative to the dollar, its central bank would sell its currency in exchange for dollars, driving down the value of its currency. Conversely, if the value of a countrys money was too low, the country would buy its own currency, thereby driving up the price. The United States Abandons the Bretton Woods System The Bretton Woods system lasted until 1971. By that time, inflation in the United States and a growing American trade deficit were undermining the value of the dollar. Americans urged Germany and Japan, both of which had favorable payments balances, to appreciate their currencies. But those nations were reluctant to take that step, since raising the value of their currencies would increase prices for their goods and hurt their exports. Finally, the United States abandoned the fixed value of the dollar and allowed it to float- that is, to fluctuate against other currencies. The dollar promptly fell. World leaders sought to revive the Bretton Woods system with the so-called Smithsonian Agreement in 1971, but the effort failed. By 1973, the United States and other nations agreed to allow exchange rates to float. Economists call the resulting system a managed float regime, meaning that even though exchange rates for most currencies float, central banks still intervene to prevent sharp changes. As in 1971, countries with large trade surpluses often sell their own currencies in an effort to prevent them from appreciating (and thereby hurting exports). By the same token, countries with large deficits often buy their own currencies in order to prevent depreciation, which raises domestic prices. But there are limits to what can be accomplished through intervention, especially for countries with large trade deficits. Eventually, a country that intervenes to support its currency may deplete its international reserves, making it unable to continue buttressing the currency and potentially leaving it unable to meet its international obligations.

Law of Tort Essay Example | Topics and Well Written Essays - 2500 words

Law of Tort - Essay Example 1. In the case of PC Black and Mrs. de Vere it is advisable that they can sue Mr Brown for making the allegations that they are involved in an adulterous relationship as well as the publishers of the Priestwich Echo for publishing this particular story. They can sue for defamation given that their reputation has been tarnished as a result of these allegations. Basically, Defamation is a group of torts which seeks to protect a person’s reputation from unwarranted attack and at first glance, these may appear to thereby protect privacy (Sweet & Maxwell, 1998). Defamation is divided into two categories namely slander (oral) and libel (published). Individuals can sue for libel as long as the permanent statement is damaging to their reputation, is false and is communicated to more than one person. It is advisable that they approach Mr Brown so that he can retract his statement if they are very sure that that it is a false allegation. If he refuses to offer an apology and retract tha t statement, they can proceed to file a suit for defamation against him as the allegations have negatively impacted on their reputation. After the publication of this story, the village is awash with this rumour and as a direct consequence of the allegations made by Mr. Brown, Mrs. de Vere was asked by the members of the Women’s Institute to resign from her position as chairwoman of the Institute for bringing the organisation ‘into disrepute.’ It is also advisable that they approach the publishers of the Priestwich Echo to retract the story and offer an apology given that they can prove the story to be wrong. However, it is also advised to Mrs de Vere and PC Black that for libel, the defences available include: justification/truth if the defendant can show that his statement was substantially true, fair comment merely expressing a truly held opinion that is a matter of public interest. Unintentional defamation and this can be retracted and innocent dissemination. The plaintiffs must prove that the statement is defamatory, it has been published and there are special damages for slander. For instance, in the case of (Duncan and Neill para 14.07, Hebditch v MacIlwaine [1894] 2 QB 54 at 58, [1891-4] All ER Rep 444 at 445 per Lord Esher MR and Adam v Ward [1917] AC 309 at 318, [1916-17] All ER Rep 157 at 160 per Lord Finlay LC), the jury held the judgement in favour of the defendants given that the issue published was a matter of public interest. It is therefore important that they can prove to the court that a case of defamation has been committed and it has directly impacted on their reputation otherwise they may lose their money for nothing filing for a losing lawsuit. It is advisable to Stuart Farqhuar, the MP to sue the publishers of the Priestwich Echo for publishing a story that is damaging to his reputation as a public figure and he can also sue Mr. Brown for making the allegations. The reporter, Joe Johnson makes reference to unsubstant iated rumours
