Ferdinand de Saussure Essay

Stylistics is the study and interpretation of texts from a linguistic perspective. As a discipline it links literary criticism and linguistics, but has no autonomous domain of its own. [1][2] The preferred object of stylistic studies is literature, but not exclusively â€Å"high literature† but also other forms of written texts such as text from the domains of advertising, pop culture, politics or religion. [3] Stylistics also attempts to establish principles capable of explaining the particular choices made by individuals and social groups in their use of language, such as socialisation, the production and reception of meaning, critical discourse analysis and literary criticism. Other features of stylistics include the use of dialogue, including regional accents and people’s dialects, descriptive language, the use of grammar, such as the active voice or passive voice, the distribution of sentence lengths, the use of particular language registers, etc. In addition, stylistics is a distinctive term that may be used to determine the connections between the form and effects within a particular variety of language. Therefore, stylistics looks at what is ‘going on’ within the language; what the linguistic associations are that the style of language reveals. * | Early twentieth century The analysis of literary style goes back to Classical rhetoric, but modern stylistics has its roots in Russian Formalism,[4] and the related Prague School, in the early twentieth century. In 1909, Charles Bally’s Traite de stylistique francaise had proposed stylistics as a distinct academic discipline to complement Saussurean linguistics. For Bally, Saussure’s linguistics by itself couldn’t fully describe the language of personal expression. [5] Bally’s programme fitted well with the aims of the Prague School. [6] Building on the ideas of the Russian Formalists, the Prague School developed the concept of foregrounding, whereby poetic language stands out from the background of non-literary language by means of deviation (from the norms of everyday language) or parallelism. [7] According to the Prague School, the background language isn’t fixed, and the relationship between poetic and everyday language is always shifting. [8] Late twentieth century Roman Jakobson had been an active member of the Russian Formalists and the Prague School, before emigrating to America in the 1940s. He brought together Russian Formalism and American New Criticism in his Closing Statement at a conference on stylistics at Indiana University in 1958. [9] Published as Linguistics and Poetics in 1960, Jakobson’s lecture is often credited with being the first coherent formulation of stylistics, and his argument was that the study of poetic language should be a sub-branch of linguistics. [10] The poetic function was one of six general functions of language he described in the lecture. Michael Halliday is an important figure in the development of British stylistics. [11] His 1971 study Linguistic Function and Literary Style: An Inquiry into the Language of William Golding’s ‘The Inheritors’ is a key essay. [12] One of Halliday’s contributions has been the use of the term register to explain the connections between language and its context. [13] For Halliday register is distinct from dialect. Dialect refers to the habitual language of a particular user in a specific geographical or social context. Register describes the choices made by the user,[14] choices which depend on three variables: field (â€Å"what the participants†¦ are actually engaged in doing†, for instance, discussing a specific subject or topic),[15] tenor (who is taking part in the exchange) and mode (the use to which the language is being put). Fowler comments that different fields produce different language, most obviously at the level of vocabulary (Fowler. 1996, 192) The linguist David Crystal points out that Halliday’s ‘tenor’ stands as a roughly equivalent term for ‘style’, which is a more specific alternative used by linguists to avoid ambiguity. (Crystal. 1985, 292) Halliday’s third category, mode, is what he refers to as the symbolic organisation of the situation. Downes recognises two distinct aspects within the category of mode and suggests that not only does it describe the relation to the medium: written, spoken, and so on, but also describes the genre of the text. (Downes. 1998, 316) Halliday refers to genre as pre-coded language, language that has not simply been used before, but that predetermines the selection of textual meanings. The linguist William Downes makes the point that the principal characteristic of register, no matter how peculiar or diverse, is that it is obvious and immediately recognisable. (Downes. 1998, 309) Literary stylistics In The Cambridge Encyclopedia of Language, Crystal observes that, in practice, most stylistic analysis has attempted to deal with the complex and ‘valued’ language within literature, i. e.  Ã¢â‚¬Ëœliterary stylistics’. He goes on to say that in such examination the scope is sometimes narrowed to concentrate on the more striking features of literary language, for instance, its ‘deviant’ and abnormal features, rather than the broader structures that are found in whole texts or discourses. For example, the compact language of poetry is more likely to reveal the secrets of its construction to the stylistician than is the language of plays and novels. (Crystal. 1987, 71). Poetry As well as conventional styles of language there are the unconventional – the most obvious of which is poetry. In Practical Stylistics, HG Widdowson examines the traditional form of the epitaph, as found on headstones in a cemetery. For example: His memory is dear today As in the hour he passed away. (Ernest C. Draper ‘Ern’. Died 4. 1. 38) (Widdowson. 1992, 6) Widdowson makes the point that such sentiments are usually not very interesting and suggests that they may even be dismissed as ‘crude verbal carvings’ and crude verbal disturbance (Widdowson, 3). Nevertheless, Widdowson recognises that they are a very real attempt to convey feelings of human loss and preserve affectionate recollections of a beloved friend or family member. However, what may be seen as poetic in this language is not so much in the formulaic phraseology but in where it appears. The verse may be given undue reverence precisely because of the sombre situation in which it is placed. Widdowson suggests that, unlike words set in stone in a graveyard, poetry is unorthodox language that vibrates with inter-textual implications. (Widdowson. 1992, 4) Two problems with a stylistic analysis of poetry are noted by PM Wetherill in Literary Text: An Examination of Critical Methods. The first is that there may be an over-preoccupation with one particular feature that may well minimise the significance of others that are equally important. (Wetherill. 1974, 133) The second is that any attempt to see a text as simply a collection of stylistic elements will tend to ignore other ways whereby meaning is produced. (Wetherill. 1974, 133) Implicature In ‘Poetic Effects’ from Literary Pragmatics, the linguist Adrian Pilkington analyses the idea of ‘implicature’, as instigated in the previous work of Dan Sperber and Deirdre Wilson. Implicature may be divided into two categories: ‘strong’ and ‘weak’ implicature, yet between the two extremes there are a variety of other alternatives. The strongest implicature is what is emphatically implied by the speaker or writer, while weaker implicatures are the wider possibilities of meaning that the hearer or reader may conclude. Pilkington’s ‘poetic effects’, as he terms the concept, are those that achieve most relevance through a wide array of weak implicatures and not those meanings that are simply ‘read in’ by the hearer or reader. Yet the distinguishing instant at which weak implicatures and the hearer or reader’s conjecture of meaning diverge remains highly subjective. As Pilkington says: ‘there is no clear cut-off point between assumptions which the speaker certainly endorses and assumptions derived purely on the hearer’s responsibility. ’ (Pilkington. 1991, 53) In addition, the stylistic qualities of poetry can be seen as an accompaniment to Pilkington’s poetic effects in understanding a poem’s meaning. Stylistics is a valuable if long-winded approach to criticism, and compels attention to the poem’s details. Two of the three simple exercises performed here show that the poem is deficient in structure, and needs to be radically recast. The third sheds light on its content. Introduction Stylistics applies linguistics to literature in the hope of arriving at analyses which are more broadly based, rigorous and objective. {1} The pioneers were the Prague and Russian schools, but their approaches have been appropriated and extended in recent years by radical theory. Stylistics can be evaluative (i. e.  judge the literary worth on stylistic criteria), but more commonly attempts to simply analyze and describe the workings of texts which have already been selected as noteworthy on other grounds. Analyses can appear objective, detailed and technical, even requiring computer assistance, but some caution is needed. Linguistics is currently a battlefield of contending theories, with no settlement in sight. Many critics have no formal training in linguistics, or even proper reading, and are apt to build on theories (commonly those of Saussure or Jacobson) that are inappropriate and/or no longer accepted. Some of the commonest terms, e. g. deep structure, foregrounding, have little or no experimental support. {2} Linguistics has rather different objectives, moreover: to study languages in their entirety and generality, not their use in art forms. Stylistic excellence — intelligence, originality, density and variety of verbal devices — play their part in literature, but aesthetics has long recognized that other aspects are equally important: fidelity to experience, emotional shaping, significant content. Stylistics may well be popular because it regards literature as simply part of language and therefore (neglecting the aesthetic dimension) without a privileged status, which allows the literary canon to be replaced by one more politically or sociologically acceptable. {3} Why then employ stylistics at all? Because form is important in poetry, and stylistics has the largest armoury of analytical weapons. Moreover, stylistics need not be reductive and simplistic. There is no need to embrace Jacobson’s theory that poetry is characterized by the projection of the paradigmatic axis onto the syntagmatic one. {4} Nor accept Bradford’s theory of a double spiral: {5} literature has too richly varied a history to be fitted into such a straitjacket. Stylistics suggests why certain devices are effective, but does not offer recipes, any more than theories of musical harmony explains away the gifts of individual composers. Some stylistic analysis is to be found in most types of literary criticism, and differences between the traditional, New Criticism and Stylistics approaches are often matters of emphasis. Style is a term of approbation in everyday use (â€Å"that woman has style†, etc.), and may be so for traditional and New Criticism. But where the first would judge a poem by reference to typical work of the period (Jacobean, Romantic, Modernist, etc. ), or according to genre, the New Criticism would probably simply note the conventions, explain what was unclear to a modern audience, and then pass on to a detailed analysis in terms of verbal density, complexity, ambiguity, etc. To the Stylistic critic, however, style means simply how something is expressed, which can be studied in all language, aesthetic and non-aesthetic. {6} Stylistics is a  very technical subject, which hardly makes for engrossing, or indeed uncontentious, {7} reading. The treatment here is very simple: just the bare bones, with some references cited. Under various categories the poem is analyzed in a dry manner, the more salient indications noted, and some recommendations made in Conclusions. Published Examples of Stylistic Literary Criticism G.

Though other scansions are certainly possible in the lines above, the most striking feature will remain their irregularity. Many lines can only roughly be called pentameters; Lines 16 and 17 are strictly hexameters; and lines 27 and 28 are tetrameters. In fact, the lines do not read like blank verse. The rhythm is not iambic in many areas, but trochaic, and indeed insistently dactylic in lines 9 and 10, 21 and 22 and 28. Line 27 is predominantly anapaestic, and line 3 could (just) be scanned: x x| / x| /| x x | /| | /| x x | Of the| heavy| surf| of the North| Sea| | flurr| ying|. Reflective or meditative verse is generally written in the iambic pentameter, and for good reason — the benefit of past examples, readers’ expectations, and because the iambic is the closest to everyday speech: flexible, unemphatic, expressing a wide range of social registers. Blank verse for the stage may be very irregular but this, predominantly, is a quiet poem, with the falling rhythms inducing a mood of reflection if not melancholy. What is being attempted? Suppose we set out the argument (refer to rhetorical and other analyses), tabbing and reverse tabbing as the reflections as they seem more or less private: {8} 1. But, as you’d expect, 2. they are very impatient, the buildings, 3. having much in them of the heavy surf of the North Sea, 4. flurrying the grit, 5. lifting the pebbles, 6. flinging them with a hoarse roar against the aggregate they are composed of — the 7. cliffs higher of course, more 8. burdensome, 9. underwritten as it were with past days 10. overcast and glinting, 11. obdurate, 12. part of the silicate of tough lives, 13. distant and intricate as 14. the whirring bureaucrats 15. Let in and settled with coffee in the concrete pallets, awaiting the post and the department meeting — 16. except that these do not know it,  17. at least do not seem to, being busy, 18. generally. 19. So perhaps it is only on those cloudless, almost vacuumed afternoons with tier upon tier of concrete like rib — bones packed above them, and 20. they light-headed 21. with the blue airiness spinning around, and 22. muzzy, a 23. neuralgia calling at random like 24. frail relations, a 25. phone ringing in a distant office they cannot get to, that 26. They become attentive, 27. or we do — 28. these divisions persisting, 29. indeed what we talk about, 30. we, constructing these webs of buildings which 31. Caulked like great whales about us, are 32.  always aware that some trick of the light or weather will dress them as friends, 33. pleading and flailing — and 34. fill with placid but unbearable melodies 35. us in deep hinterlands of incurved glass. The structure should now be clear. Where Eliot created new forms by stringing together unremarkable pentameters, {8} this poem attempts the reverse: to recast an irregular ode-like structure as pentameters. And not over-successfully: many of the rhythms seemed unduly confined. But once returned to the form of an eighteenth century Pindaric ode, however unfashionable today, the lines regain a structure and integrity. Each starts with a marked stress and then tails away, a feature emphasized by the sound patterns. {9} Sound Patterning To these sound patterns we now turn, adapting the International Phonetic Alphabet to HTML restrictions: 1.

Of the seventeen different employments listed by Masson {10} we consider seven: 1. Structural emphasis All sections are structurally emphasized to some extent, but note the use (in decreasing hardness) of * plosive consonants in sections 1, 5, 6, 7, 10-13, 19, 28-50; 31 and 35. * fricative and aspirate consonants in sections 2, 3, 6, 7, 12, 19, 25, 28, 32, 35. * liquid and nasal consonants in sections 3, 4, 12, 15, 17, 18, 19, 21, 23, 31-35. Also: * predominance of front vowels — in all sections but 6, 7, 11, 16, 17, 19 and 31. * predominance of vowels in intermediate positions — only sections 16 and 17 having several high vowels and section 3 low vowels. 2. Tagging of sections Note sections 1, 7, 13 and 15. 3. Indirect support of argument by related echoes * Widely used, most obviously in sections 3-7, 12-13, and 15. 4. Illustrative mime: mouth movements apes expression * Sections 2, 6, 11-13, 19, 31 and 35. 5. Illustrative painting * Sections 3-6, 10-13, 15, 19 and 33. Most sections are closely patterned in consonants. Those which aren’t (and therefore need attention if consistency is to be maintained) are perhaps 8, 9, 14, 18, 20, 22, 24, 26 and 27. Originally the poem was cast in the form of irregular pentameters. But if this is set aside in favour of the 35 sections listed above, how are these sections to be linked in a self-evident and pleasing form? A little is accomplished by alliteration: * f in sections 3 to 7. * s and t in sections 12 to 15 * w in sections 29 to 32 And also by the predominance of front and intermediate level vowels, but these do not amount to much. Certainly we do not find that the overall shaping of the poem emphasizes the argument or content. Sociolinguistics Language is not a neutral medium but comes with the contexts, ideologies and social intentions of its speakers written in. Words are living entities, things which are constantly being employed and only half taken over: carrying opinions, assertions, beliefs, information, emotions and intentions of others, which we partially accept and modify. In this sense speech is dialogic, has an internal polemic, and Bakhtin’s insights into the multi-layered nature of language (heteroglossia) can be extended to poetry. {11} Much of Postmodernist writing tries to be very unliterary, incorporating the raw material of everyday speech and writing into its creations. This poem seems rather different, a somewhat remote tone and elevated diction applying throughout. Let us see what’s achieved by grouping under the various inflections of the speaking voice. * urgently confidential But, as you’d expect, cliffs higher, of course, that they become attentive or we do * obsessively repetitious flurrying the grit, lifting the pebbles, flinging them†¦ Burdensome, underwritten†¦ overcast and glinting, obdurate * over-clever silicate of tough lives  distant and intricate constructing these webs of buildings distracted and/or light-headed except that these do not know it at least do not seem to with the blue airiness spinning around calling at random like frail relations * melancholic and/or reflective some trick of the light or weather will dress them as friends pleading and flailing and fill with placid but unbearable melodies. The exercise hardly provides revelation. Heteroglossia is an interweaving of voices, moreover, not shifts of tone or reference. And yet there is something very odd about the opening line. Why should we expect the buildings to be very impatient? This is more than the orator’s trick of attracting attention, since the animate nature of buildings and their constituents is referred to throughout the poem. To be more exact, the attitude of the inhabitants — observers, bureaucrats, architects — to the buildings is developed by the poem, and is paralleled by the tone. But why the confidential and repetitious attitude at the beginning. Why should we be buttonholed in this manner? Why the But, which seems to point to an earlier conversation, and the urgency with which that earlier conversation is being refuted or covered up? Because the blame for something is being shifted to the buildings. What error has been committed we do not know, but in mitigation we are shown the effect of the buildings on other inhabitants. Or perhaps we are. In fact the whirring bureaucrats seem to grow out of the fabric of buildings, and we do not really know if the we, constructing these webs of buildings is meant literally or metaphorically. The poem’s title suggests literally, but perhaps these constructions are only of the mind: sections 17, 20-29, 32 and 34 refer to attitudes rather than actions, and there is an ethereal or otherworldly atmosphere to the later section of the poem. So we return to heteroglossia, which is not simply borrowed voices, but involves an internal polemic, {12} that private dialogue we conduct between our private thoughts and their acceptable public expression. The dialogue is surely here between the brute physicality of a nature made overpoweringly real and the fail brevity of human lives. That physicality is threatening and unnerving. If the we of the later section of the poem is indeed architects then that physicality is harnessed to practical ends. If the constructing is purely mental then the treatment is through attitudes, mindsets, philosophies. But in neither case does it emasculate the energy of the physical world. Architects may leave monuments behind them, but they are also imprisoned in those monuments (us in deep hinterlands) and hearing all the time the homesick voice of their constituents. Conclusions: Suggested Improvements The greatest difficulty lies in the poem’s structure. An pentameter form has been used to give a superficial unity, but this wrenches the rhythm, obscures the sound patterns and does nothing for the argument. If recast in sections defined by rhythm and sound pattern the form is too irregular to have artistic autonomy. A return could be made to the eighteenth century Pindaric ode in strict metre and rhyme, but would require extensive and skilful rewriting, and probably appear artificial. A prose poem might be the answer, but the rhythms would need to be more fluid and subtly syncopated. Otherwise, blank verse should be attempted, and the metre adjusted accordingly. The internal polemic is a valuable dimension of the poem, but more could be done to make the voices distinct. http://www. textetc. com/criticism/stylistics. html1. On StylisticsIs cognitive stylistics the future of stylistics? To answer this question in the essay that follows, I will briefly discuss Elena Semino and Jonathan Culpeper’s Cognitive Stylistics (2003), Paul Simpson’s Stylistics (2004), and a recent essay by Michael Burke (2005). However, because questions are like trains – one may hide another – any discussion of the future of stylistics raises intractable questions about stylistics itself. French students of stylistics, for example, will come across definitions of the discipline like the following.

Money Changes People

Money Changes People There was a time period were I was very wealthy, were I can get mostly everything I wanted. My family and I would go to Vegas every single weekend and when it came to my birthday we would go to chucky cheese but not just any chucky cheese, we would go to Beverly Hills chucky cheese. Well one day all of that went down hill, my father got obsessed in buying any random shit from the store that we didn’t even need he would always say â€Å"we’ll need this one day† but that one day never came.It was a hot summer day when our payment of our house but now we couldn’t even pay because we ran out of money just because my dad, but I wouldn’t blame him only because I would buy some random game that wasn’t even worth buy it and I didn’t play it all. Well there was only 3 more days to pay or the police would come and I panicked and I call my mom and dad over so I can talk to them. I tell them in a very confident tone â€Å"um, so I’ve been thinking why don’t we steel the bank down the block by olive garden, you the place we used to eat in very special days? I was scared to what they would say but they say what I wanted them to say â€Å"well that’s our only choice to do son since that’s the fastest thing to do. † That reply satisfied my life. The next day we go very early because we didn’t want anybody to hurt in any way. My dad knows a guy who can give us some bulletproof vests and a rifle and a handgun. â€Å"I’m very nervous† said my mom in a scared tone. â€Å"C’mon mom we can do this just don’t bother with vault cause they have a chemical where it throws blue ink at your face so just stick with the tellers. â€Å"Ok son lets do this, are you ready? What about you Hun? † â€Å"Yes mom I’m ready†¦Ã¢â‚¬  â€Å"I’m also ready, lets get this over with†¦Ã¢â‚¬  we go in side and there are no people but the manager and a co-worker, so that was the best moment to get in. my dad and I scream out â€Å"put your hands up and get on the floor† we tell the police inside to drop the gun and give it to me. He failed to do so, so I shoot him in the leg and drops down to the floor he quickly tries to shoot me but I stopped him and shot him in the head and all you see is the brain on the wall dropping down slowly.My mom told me to go and take the money, and I put on my gloves on and I go to the tellers, they only had 400,000 dollars which didn’t fill us up so we decide to go to the vault and we take 3. 5 million dollars, I didn’t know why they had so much money but then 5 min. later we left the place and then the bus guy who would collect the money comes and see’s the dead guy on the floor, he decides to call the police but before he did that my dad gets his rifle and shoots him right in the heart.My mom and my dad said something at the same time â€Å" lets hide the bodies and leave but before we did that we hear a loud bang and it was the co-worker who we forgot all about so we take her also and putted them into a dumpster. It’s been 3 years since that happened and we’re all gone from LA and we went to good old Washington, which my mom had a dream living there. My dad on the other he has changed a lot, now he has a job and finally got the hang of taking care of the money and how to use it and how to buy the right things we needed. Hi son do you remember what happened 3 years ago? † â€Å"How can I not remember that, that was the best day of my life, I had so much fun except those people we killed. † â€Å"Yes I guess it was fun. † Now it’s been 10 years since that happened and now we’re wealthier than the richest man in Washington. Why, would you ask? Its simple, my dad created the anti theft alarm for cars and stores and even a bank.He got the idea of this 2 years ago when he said â€Å"Ià ¢â‚¬â„¢m going to create this so no other dumbass would do the same shit we did† â€Å"I agree dad you should create this† â€Å"yes Hun we would make a very good investment. † Well it was a great success and he made 1. 2 trillion dollars. I told my dad that I wanted to help the poor and people who don’t have enough money to even survive one day and he gave me a positive answer â€Å"yes son go ahead here’s 2 million dollars, go do a good thing with that money. â€Å"Thank you dad I love you† â€Å"I love too son. † The very next day I went out to the streets and gave every homeless person 100 dollars and made an organization of helping the poor a gave the rest that I have and gave everyone in Africa food and supplies to survive. That lasted 5 years and the closing of my organization I made a speech and it went like this â€Å"hi kids, family and parents, I here to say that I’m very happy to what happen a few years ago when I started all of this.All of you here are maybe asking your, why did he do this? Well I did this because I went through this when I was younger and me and my family were starving and we had to survive, umm I prefer you to read my book I made called â€Å"my survival story† thank you for time and good bye. So my life has changed and my dad and my mom are busy going around the world helping people while I stay here and try to survive another day like anybody would do.

Analysis of FedEx marketing channels

Analysis of FedEx marketing channels Generally, a channel designed to make the service available to customers. A service without good marketing channel consider useless because it is not accessible for customer to get the service. FedEx as a service company that mainly focuses on transportation or shipment services, channel played an important role leading to success. FedEx need a good channel to get and reach more customers.

FedEx h as many hubs around the world working as a midpoint of delivering the packages. There are four hubs in Asia pacific. That is Shanghai, Osaka, Seoul and Guang Zhou. Besides, FedEx has hubs in London, Colonge, Frankfurt and Paris which will later ship the parcel around the European area. Moreover, hubs that link the Latin America, the Caribbean and Canada was in Memphis and Miami. One thing that makes FedEx so special out of so many transportation or shipping company is the collection of airplane uses by FedEx in order to ship the parcel. FedEx is the first company who use the plane called Boeing 777. The uniqueness of the plane is the plane is fuel saver. It shorter the transit time with larger space to put the parcel. This had made the overnight carrier service possible. FedEx was famous in its overnight service. Customers can receive their packages at the same time on the next day. The strong backbone of shipping network structure by FedEx makes this service available. An example g iven to explained how FedEx manage to ship the parcel between 24 hours and reach at 10.30am. A customer decided to ship his parcel from Shang Hai to New York City. FedEx pick up the shipment in time to make the same-day trans-oceanic flight. FedEx picked up the package from client at the time of 4:50 pm, Tuesday. The package was delivered to Shang Hai’s facility for sorting process.

The Scientific Reasoning Level of Students In the Faculty of Science Research Proposal

The Scientific Reasoning Level of Students In the Faculty of Science In King Saud University - Research Proposal Example It is important to establish how scientific reasoning capability affect the way students choose the subjects to specialize in. Students within the faculty of science in King Saudi University can choose to specialize in Biology, Chemistry, or Physics. It is also important to establish the scientific reasoning capability of students in the four learning levels in King Saud University to determine whether their understanding of different scientific concepts is progressing or not. Literature Review A lot of research has been done on factors that determine performance of students in science and the scientific reasoning. Such studies have shown that scientific reasoning is imperative and it enables students predict and apply different scientific theories. A study conducted by Bell, Maeng & Peters (2010, p. 8) showed that students enjoy challenges posed by scientific inquiry and take part more devotedly when supported. The study also showed that most teachers do not exhibit natural ability in providing instructions and teaching on the nature of science thus students interest in science and scientific reasoning capability tends to depreciate as they proceed to higher teaching levels. Schen (2007, p. 86-88) did a study to investigate development of scientific reasoning among undergraduate students majoring in Biology. The study made use of Lawson Classroom Test of Scientific Reasoning (LCTSR) to assess student’s scientific reasoning capability. The study results showed that there is need to foster development of reasoning skills among undergraduate biology students to improve the reasoning skills of future scientists. Schen concluded that undergraduate students pursuing biology may be having difficulty in understanding scientific methods well since they are not evolving their mental reasoning skills (Schen, 2007, p.142). Moore and Rubbo (2011, p.3) did another research to determine scientific reasoning abilities of non-science majors in physics-based courses. The study results showed that students in non-scientific physics based courses, which included conceptual physics and astronomy courses score considerably lower on the LCTSR compared to students enrolled in courses with science majors (Moore & Rubbo, 2011, p.8-11). Another study was done by Benford and Russell (2001, p.2) and aimed at examining the connection between scientific methodologies and biological inquiry methods in college biology laboratories. The study established a negative relationship between lecturer or instructor inquiry and student understanding of nature of science. The study also showed that most biology students have low scientific reasoning capability. Little research has been done on how scientific reasoning differs in different scientific specialization such as Biology, Chemistry, and Physics. Additionally, there is less literature comparing the trend of scientific reasoning across different levels of study. This study is thus important since it aims at establis hing if there is any difference in scientific reasoning in the different specialization as well as in the different levels of study. Background and Objective The level of scientific reasoning determines how student perceive different aspects of science, which in turn determine the science subject they choose to major in. The scientific concepts vary from one level of study to

Public Policy Analysis - SARBANE OXLEY Essay Example | Topics and Well Written Essays - 2750 words

Public Policy Analysis - SARBANE OXLEY - Essay Example Oxley. Over the years, the act has managed to establish a myriad of deadlines for its compliance. This act was adopted mainly to uplift the standards in corporate governance, analysis of securities and performance of audit work. According to Cohen, Dey & Lys (2007), before the introduction of this policy there were numerous Securities and Exchange Commission violations, gross lack of corporate quality control and ethical behavior in companies resulting in many corporate scandals and filing of criminal actions against corporations, shareholders, company directors, and finally company officers. The Sarbanes-Oxley Act came into effect in the wake of some of the nations enormous financial scandals. The Act is believed to initiate most of the dramatic changes to the federal laws since 1930s. It further prescribes punishment for violators of the Act ranging from prison sentences to multimillion-dollar penalties. The main idea that the editors of this act had in mind was to protect investor s by improving the accuracy and reliability of corporate disclosures made pursuant to the securities laws. Over the years, the government of the United States of America has adopted this policy and many security policies have been drafted in reference to this act. SOX applies to all public companies in the United States not excluding international companies that have registered equity or debt securities with the Securities and Exchange Commission and the accounting firms that provide auditing services to them. According to Bartlett and Richard the Sarbanes-Oxley Act has created new standards for corporate accountability and also new penalties for acts of incompliance. It has changed how corporate boards, executives and corporate auditors interact with each other. In addition, it also removes the common excuse of claiming that one was not aware of a mistake when he or she made it on matters pertaining to finances. This mainly involves the CEOs and CFOs, as it holds them accountable f or the accuracy and errors of financial statements (DMPL). The Act specifies new financial reporting responsibilities and these include adhering to new internal controls and procedures formulated to ensure that financial records are valid. The Act makes it a federal crime to for a company to force or manipulate an auditor into signing off incorrect financial statements thus preventing company directors and officers from obtaining personal benefits from dubious financial statements. Moreover, the Act stipulates that the board of directors in almost all public companies should have an audit committee. The committee is tasked to appoint, regulate, inspect and exercise control over the company’s auditing firm. As result the auditors are to directly report to the audit committee. Rationale for public policy-Market failure This highlights how the concept of market failure applies to ethical corporate governance to give an insight in corporate ethics’ authenticity in the mode rn corporation and the probability of the Sarbanes-Oxley achieving its desired results. When large companies like Enron, WorldCom and Tyco just to name a few were struck with enormous cases of corporate fraud, the necessity to find for an amicable solution was very vital. This is because millions of dollars were embezzled by the CEOs and CFOs through customized balance sheets. Companies incurred considerable loss of profits

Marriage Essay Example | Topics and Well Written Essays - 1500 words

Marriage - Essay Example This paper will look closely at the factor of having the right partner for the marriage and if it can help to cement a stable relationship. But first let us explore the institution of marriage and the dynamism of the institution The question that linger in our mind is what is the real cause of such instability in our marriages Though this question is hard to answer, there are some obvious answers that any one of us can give as the main cause of such instability in the marriage institution in the modern world. In order to find the appropriate answer to this question, we should first look at the cause of that may be leading to high rate of divorces in our society. Let us look at some of these causes There are many causes of divorce in our modern society. The leading cause of divorce and instability in our marriage has been identified as economic issues in marriage. Though many people and many psychological counselors tend to downplay this issue, it is the leading cause of many divorces. It has been shown that there is high rate probability for divorce in case one of the partners loses income. Economic constrain in marriages leads to conflict on most issues in the households. The modern marriage has been commentated on basis of equal contribution by both partners who came into force with the end of full time mothers. In our traditional society, husbands were given the duty of providing fro the families but this has changed over time with the coming of modern notion of full time career mothers. As a result husbands have been reluctant in providing for their families alone if their wives are working. Hence in case where both the husband and the wives are working, failure by one partner to remit their contribution to the maintenance of the family is one of the leading factors causing instability in marriages. Many of divorce cases that have been filed have resulted from the economic hardship faced by one of the parties in marriages. It has been observed that most of divorce cases filed on economic ground is fronted by wives. Therefore economic issues are one of the factors in stability of the marriage that goes beyond the issue of whether one is having the right partner or not. (Cooper, 2006) The other cause of divorces in marriage has been infidelity from one or both of the partners. In many instances, sexual dissatisfaction has been one of the leading factor causing breakdown of many marriages. Infidelity has become norm in most modern marriages with many partners citing sexual dissatisfaction as the main cause of their infidelity. The issue of infidelity goes beyond the compatibility of partners in marriage and the breakdown in married couple with declining value of the institution can be identified as the leading factors causing infidelity. Sexual deprivation come as a second issue in marriage conflict which means there has to be a primary issue that is causing this dissatisfaction and which leads to infidelity. The other issue that can be identified

A biologist is a scientist that studies organisms to produce results of biological significance. The fundamental objective of a biologist is to determine the impact of environment upon organisms and of organisms upon environment. The field evolved as more research was done to see how organisms function. The job of a biologist that does applied research is to find out innovative treatments and cures for medical conditions. Some biologists supervise the research and coordinate things among the parties involved, thus playing the role of a manager in the process. The US Government Bureau of Labor Statistics tells that the annual salary of a biologist on average is nearly $57000 (â€Å"Biologist Salary†).

Queer film +video Essay Example | Topics and Well Written Essays - 750 words

Queer film +video - Essay Example One the recent film that easily and best represent Doty’s queer theory is the animation film Hotel Transylvania Directed by Genndy Tartakovsky. The film became queer because a movie along with its characters are supposed to be queer and scary but the movie presented it as non-threatening, mainstream and to some extent, even romantic. The rendition of the film is the reverse of Doty’s assertion that sometimes what is considered as normal rendition of a film can be the most queer of all. The film literally dislodged the viewers traditonal concept of supernatural entities. For example, Dracula has a daughter who wants to be friends with humans and runs a hotel for monsters. Transylvania in this film is in fact a hotel and not the regular impression of an old scary castle. Werewolves and vampires are also relatives (Daughter Mavic called Wayne and Wanda as aunt and uncle) instead of being mortal enemy. Frankenstein has a wife and above all, it is the humans who are in fact â€Å"monstrous† that they should be scared of. And lastly, monsters in fact loves to party. It also talks about sexuality only not in the queerness of homosexuality but rather the emerging sexual drive of a teenage vampire that put normalcy in an otherwise abnormal character of a vampire. Perhaps the biggest queerness of the film was the reversal of roles between humans and monsters (vampires, werewolves, big foot, mummy). The supposed culturally marginal, in Doty’s words (4) became the dominant culture and the dominant culture became marginalized. In the point of view of the monsters, they are the mainstream entities and humans are considered as sub entity and are the ones that are monstrous that should be feared. Tartakovsky made an interesting confrontation of his characters who assumed reversal of role where the monsters view the human (young traveler Jonathan who became the fiancee of Mavic) as monstrous and the human not threatened by the actual

Natural Science Essay Example for Free

Natural Science Essay The relevance of this test question is to determine which brand of leading paper towels is the best most absorbent. Consumers want to use the product that is most effective at meeting their needs. A more expensive product may actually be more cost effective if you can use less of it than a brand that costs less. Literature Review Many experiments have been conducted to test the strength and absorbency of paper towels. While the steps of the experiment vary from test to test, all of experiments are testing the same two factors; how much water can each paper towel brand absorb and how strong are each of the paper towels. Below I have reviewed the process and results from three experiments that are similar to the one I will be using. In the first experiment, the tester uses five brands of paper towels to test for absorbency, using paper towels of the same size to ensure the accuracy of the results. He draws a two inch circle in the center of a sheet of paper towel from each brand represented and placing the paper towel in an embroidery hoop to maintain stability. He then drops fifteen drops of water into the center of the circle draw on the paper towel, repeating the process for each brand, and measures the amount of time it takes the paper towel to wick the moisture outside of the circle. This test concludes that Bounty has the greatest absorbency. The next experiment tests for both absorbency and strength. As in the first test, several different brands of paper towels were used. In this experiment, to test the absorbency, the tester takes a sheet of each of the towels an inserts it into a glass with two ounces of water and leaves each sit for twenty seconds. After the twenty seconds expired, the tester removed the paper towel from the glass and rang out each paper towel into a measuring cup to see how much water each towel had absorbed. The second part of the experiment is conducted by stretching sheets of each paper towel through an embroidery hoop, placing 25 pennies in the center of the paper towel, and adding water to the towel drop by drop until the pennies fall through. The strongest paper towel in this test was Brawny Brand. The final experiment that I reviewed also tested for absorbency. The theory behind this experiment was the faster that water moves through the towel, the more absorbent it is. The experimenter cut strips from each paper towel, one inch wide and six inches long. A mark is drawn on each paper towel one inch from the end using a waterproof marker. The strip is then held in a glass of water with the bottom inch submerged, timing how long it takes for the water to travel the length of the strip. The process is then repeated for each brand that is being tested. The most absorbent brand in this test was Brawny. Experimental Design A. Steps in Experimental Procedure The absorbency of the towels will be tested by the speed the water moves through the paper towels, the faster the water moves, the more absorbent the towel is. I will be using the following brands of paper towels in my experiment: Brawny, Bounty, Sparkle and Scott. Other supplies necessary to complete the experiment are: a waterproof marker, and a sixteen-ounce glass of water, and a timer that registers tenths of a second. 1. Prepare three samples of paper towel from each brand by cutting strips of each that is 2 inches wide and six inches long. 2. Using a water-proof marker, draw a line across each paper towel one inch from the bottom. 3. Fill a sixteen ounce glass with water and prepare timer. 4. Take the first strip of paper towel and submerge it up to the line in the glass of water while holding it vertical to the glass while starting the timer. 5. Allow the timer to run until the water is absorbed through the paper towel and reaches the end of the towel not submerged. 6. Stop the timer and record the time in tenths of seconds. 7. Repeat steps 4 through 6 for all three strips of each brand. B. Reasoning for Choosing my Experimental Design Plan The reason I chose this design for my experiment is because it seemed to be more accurate than other testing methods I found during my literature review and could be performed with items I already had in my home. The experiment where the tester rang out the paper towels and measure the water that they had absorbed is less accurate because there is no guarantee of exerting the same amount of force each time you ring out a towel. There is no way to completely drain the towel of all of the liquid it absorbed. Stretching the paper towel samples across the embroidery frame is sound way to perform the experiment but it would have required the purchase of additional materials. C. Sequence of Events to Collect Quantitative Data I will begin the collection of quantitative data by cutting the paper towel samples from each brand into strips that are one inch wide by six inches long, to ensure that all of the samples will be equal. I will use the same glass of water for each test to ensure the water composition is the same for each test. I have created a spreadsheet in excel with a column listing each of the brands being tested and three columns for the time in tenths of a second to be entered upon completion of the experiment. During the experiment, I will make notes on a tablet of the brand name and the time recorded to be entered into the spreadsheet upon completion of the entire experiment. D. Describe Tools, Technologies, and Measurement Units that are used to Collect the Data To collect the data for this experiment I will use one inch wide by six inch long strips of paper towel from each of the brands being tested, a black water-proof marker to mark the strips of paper towel, an eight ounce glass of water, my hand to hold the strip vertical to the glass once submerged as indicated in the experimental procedure, a timer that measures tenths of a second, and a pad and pencil to record the initial results. Once the experiment is complete I will transfer the results of the experiments to the spreadsheet that I have created using Microsoft Excel. I will also use excel to create the graphic representation of the experiment results. Dependent, Independent and Controlled Variables of the Experiment The independent variable in my paper towel experiment is the one inch by six inch strip of paper towel taken from a roll of each brand of paper towel used in the experiment. The dependent variable in the experiment is the amount of time it takes the water to travel the length of the strip of paper towel measured in tenths of a second. The controlled variables of the experiment are using the same glass of water, same size sample of paper towel, and same timer for each test in the experiment. Threat Reduction to Internal Validity To reduce internal threats to validity I will use the same size piece of each paper towel from each brand for each test to conduct the experiment, marking each piece with a line at exactly one inch from the bottom. I will use the same water sample to ensure the liquid being absorbed by each sample strip is identical; the same timer will be used for each test to ensure the accuracy of the time recorded for each test. I will also monitor my results for outliers in the time required to absorb the water through each test towel to ensure the results are valid for each test. Hypothesis The sample of Bounty paper towels will soak up the water through the length of paper towel faster than the other brands because it is thicker than the other brands being tested. I have arrived at this conclusion because the dual layers of towel that are present in the sample of Bounty create a greater surface to absorb water. The other brands are much thinner and have less thickness to soak up water.

What Are The Concepts Of Thermochemistry Environmental Sciences Essay

What Are The Concepts Of Thermochemistry Environmental Sciences Essay The beginnings of modern thermochemistry, though made independently of the doctrine of the conservation of energy, are practically contemporaneous with the recognition of that law, and without it the science could scarcely have reached the degree of development which it rapidly attained. Thomas Andrew and, especially Hess were the first who systematically investigated thermochemical effects in solution, and arrived at conclusions from their experimental data which still possess validity. Andrews, for example, found that when a series of acids were under similar conditions used to neutralize a given amount of a base, the quantity of heat evolved on the neutralization was the same in all cases. Hess, from his work, arrived at the converse conclusion, that when a series of bases were used to neutralize a given amount of an acid, the heat of neutralization was always the same. Both of these statements are correct when the powerful mineral acid and bases are considered, exceptions only ar ising when weak acids and bases are employed. Again, Andrews discovered that when one metal displaces another from solution of its salts (e.g. zinc with solutions of copper salts), the thermal effect is practically independent of the nature of the acid radical in the salt employed. Andrews likewise found that when the heat evolved on. the displacement from its salts of a metal M by a metal M is added to the heat of displacement of another metal M by M, the sum is equal to the heat which is evolved on the direct displacement of M from its salts by M. This affords an example of a principle which had been stated by Hess in a very general form under the name of the Law of Constant Heat Sums namely, that the thermal effect of a given chemical action is the same, independently of the character and number of the stages in which it takes place. Thus, in the above example, it is immaterial whether M displaces M from its salt directly, or whether M first displaces M, which is then used to di splace M. This important principle is a direct consequence of the law of the conservation of energy, but was discovered independently by Hess from accurate experiment.

Thus the heat of formation of anhydrous zinc sulphate, ZnSO 4j which cannot be determined directly, may be arrived at by summation (in Hesss units) as follows: Heats of formation are still determined for the most part in a precisely similar manner. Hess also stated another principle on empirical grounds, which, although admitting of many exceptions, is of considerable utility and significance. It had been known long before his time that when solutions of neutral salts were mixed, and no precipitate resulted, the mixed solution was also neutral. Hess now observed that in the process of mixing such neutral solutions no thermal effect was produced that is, neutral salts in aqueous solution could apparently interchange their radicals without evolution or absorption of heat. These experimental results were generalized by him under the title of the Law of Thermoneutrality. After the investigations of Hess and Andrews, a great deal of excellent experimental work was performed by P. A. Favre and J. T. Silbermann, whose chief theoretical achievement was the recognition that the heat of neutralization of acids and bases was additively composed of two constants, one determined by the acid and the other by the base. This dedction harmoniz ed the observations of Andrews and of Hess previously alluded to, and also accounted satisfactorily for the Law of Thermoneutrality. Julius Thomson was the first investigator who deliberately adopted the principle of the conservation of energy as the basis of a thermochemical system. His thermochemical work was begun in 1853, but most of his experiments were performed in the years 1869-82, the whole being published collectively, under the title Thermochemische Untersuchungen, in four volumes. Somewhat later than Thomson, Marcellin P. E. Berthelot began (in 1873) a long series of thermochemical determinations. It is to these two investigators and their pupils that most of our exact thermochemical data are due. Thomsen and Berthelot independently enunciated a generalization (commonly known as Berthelots Third Principle, or Principle of Maximum Work), which may be stated in brief as follows: Every pure chemical reaction is accompanied by evolution of heat. Whilst this principle is undoubtedly applicable to the great majority of chemical actions under ordinary conditions, it is subject to numerous exceptions, and cannot therefore be taken (as its authors originally intended) as a secure basis for theoretical reasoning on the connexion between thermal effect and chemical affinity HEAT IN THERMOCHEMISTRY . The existence of reactions which are reversible on slight alteration of conditions at once invalidates the principle, for if the action proceeding in one direction evolves heat, it must absorb heat when proceeding in the reverse direction. As the principle was abandoned even by its authors, it is now only of historical importance, although for many years it exerted considerable influence on thermochemical research. 2. From the standpoint of the law of conservation of energy, the relation between chemical and thermochemical action bears the following aspect: A given amount of any substance under given conditions possesses a perfectly definite amount of intrinsic energy, and, no matter what chemical and physical transformations the substance may undergo, it will, when it returns to its original state, possess the original amount of intrinsic energy. If we consider now the transformation of one system of chemical substances into another system under specified conditions, we shall find that in general the intrinsic energy of the second system is different from the intrinsic energy of the first. Let us assume, as is commonly the case, that the intrinsic energy of the initial system is greater than that of the final system. When the first system then is transformed into the second, the excess of energy which the former possesses must appear in the shape of heat, light, electrical energy, mechanical energy, c. It is for the most part a simple matter to obtain the excess of energy entirely in the form of heat, the amount of which is easily susceptible of measurement, and thus the existence of thermochemistry as a practical science is rendered possible. Since the intrinsic energies of the two systems under given conditions are invariable, the difference between them is constant, so that the heat evolved when the first system is converted into the second is equal to that absorbed when the second system is re-transformed into the first (cf. Lavoisier and Laplace, ante, 1). The total thermal effect, too, which is associated with the transformation, must be the same, whether the transformation is conducted directly or indirectly (Hesss Law of Constant Heat Sums), since the thermal effect depends only on the intrinsic energies of the initial and final systems. Since the intrinsic energy of a substance varies with the conditions under which the substance exists, it is necessary, before proceeding to the practical application of any of the laws mentioned above, accurately to specify the conditions of the initial and final systems, or at least to secure that they shall not vary in the operations considered. It is also a necessary condition for the application of the preceding laws that no form of energy except heat and the intrinsic energy of the substances should be ultimately involved. For example, when metallic zinc is dissolved in dilute sulphuric acid with production of zinc sulphate (in solution) and hydrogen gas, a definite quantity of heat is produced for a given amount of zinc dissolved, provided that the excess of energy in the initial system appears entirely as heat. This provision may not always be fulfilled, since by placing the zinc in electrical contact with a piece of platinum, likewise immersed in the sulphuric acid, we can g enerate a current of electricity through the solution and the metallic part of the circuit. The reaction as before is completely expressed by the chemical equation Zn+H2S04 =ZnSO 4 H+ 2, the initial and final systems being exactly the same as in the first case; yet the amount of heat generated by the action is much smaller, a quantity of the intrinsic energy having been converted into electrical energy. This electrical energy, however, is equivalent to the heat which has disappeared, for it has been shown experimentally that if it is converted into heat and added to the heat actually evolved, the total quantity of heat obtained is exactly equal to that produced by the direct dissolution of the zinc in the absence of platinum. 3. The following conditions have to be considered as affecting in a greater or less degree the intrinsic energy of the initial and final systems: (1) Dilution of solutions. (2) Physical state. (3) Change of volume. (4) Allotropic modifications. (5) Temperature. (i) Generally speaking, there is a considerable thermal effect when a substance is dissolved in water, and this effect varies in magnitude according to the amount of water employed. It is only, however, when we deal with comparatively concentrated solutions that the heat-effect of diluting the solutions is at all great, the heat-change on diluting an already dilute solution being for most practical purposes negligible. In dealing, therefore, with dilute solutions, it is only necessary to state that the solutions are dilute, the exact degree of dilution being unimportant. It occasionally happens that a change in dilution affects the chemical action that occurs. Thus if concentrated instead of dilute sulphuric acid acts upon zinc, the action takes place to a great extent not according to the equation given above, but according to the equation Zn +2H 2 SO 4 = ZnS04+S02+2 H20, sulphur dioxide and water being produced instead of hydrogen. Here we have a different final system with a diffe rent amount of intrinsic energy, so that the thermal effect of the action is altogether different. (2) The physical state of the reacting substances must be considered, since comparatively large amounts of heat are absorbed on fusion and on vaporization . Thus the heat of fusion of ice(for H 2 O=18 g) is 1440 cal., and the heat of vaporization of water at 100 °, for the same quantity, 9670 cal. (3) The effect of change of volume against external pressure (due to production or consumpion of mechanical energy) may be neglected in the case of solids, liquids or solutions, but must usually be taken into account when gases are dealt with. Each grammemolecule of a gas which appears under constant pressure during a chemical action (e.g. hydrogen during the action of zinc on dilute sulphuric acid) performs work equivalent to 580 cal. at the ordinary temperature, which must be allowed for in the thermochemical calculation. A similar correction, of opposite sign, must be made when a gramme-molecule of gas disappears during the chemical action. (4) When a substance e.g. carbon, phosphorus , sulphur exists in allotropic forms, the particular variety employed should always be stated, as the conversion of one modification into another is frequently attended by a considerable thermal effect. Thus the conversion of yellow into red phosphorus evolves about one-sixth of the heat of combustion of the latter in oxygen, and so the knowledge of which variety of phosphorus has been employed is of essential importance in the thermochemistry of that element. (5) The influence of temperature on the thermal effect of a chemical action is sometimes considerable, but. since the initial and final temperatures, which alone determine the variation in the thermal effect, are in almost all cases within the ordinary laboratory range of a few degrees, this influence may in general be neglected without serious error. 4. Methods. In order to estimate the thermal effect of any chemical process, use is made of the ordinary methods of calorimetry, the particular method being selected according to the nature of the chemical action involved. In almost every case the method of mixture (see Calomitry) is employed, the method of fusion with Bunsens ice-calorimeter being only used in special and rarely occurring circumstances. As a very great number of important chemical actions take place on mixing solutions, the method for such cases has been thoroughly studied. When the solutions employed are dilute, no water is placed in the calorimeter, the temperature-change of the solutions themselves being used to estimate the thermal effect brought about by mixing them. Known quantities of the solutions are taken, and the temperature of each is accurately measured before mixing, the solutions having been allowed as far as possible to adjust themselves to the same temperature. The change of temperature of the solutions after the mixing has taken place is then observed with the usual precautions. It is of course in such a case necessary to know the specific heat of the liquid in the calorimeter. Thomsen by direct experiment found that the heat-capacity of a dilute aqueous solution diverged in general less than i per cent. from the heat-capacity of the water contained in it, the divergence being sometimes in one sens e, sometimes in the other. He therefore abstained from determining for each case the specific heats of the solutions he employed, and contented himself with the above approximation. Berthelot, on the other hand, assumed that the heat-capacity of an aqueous solution is equal to that of an equal volume of water, and calculated his results on this assumption, which involves much the same uncertainty as that of Thomsen. Since thermochemical measurements of this type may be frequently performed with an error due to other causes of much less than i per cent., the error introduced by either of these assumptions is the chief cause of uncertainty in the method. The calorimeter used for solutions is usually cylindrical, and made of glass or a metal which is not, attacked by the reacting substances. The total quantity of liquid employed need not in general exceed half a litre if a sufficiently delicate thermometer is available. The same type of calorimeter is used in determining the heat of solution of a solid or liquid in water. Combustion calorimeters are employed for observing the heat generated by the brisk interaction of substances, one of which at least is gaseous. They are of two kinds. In the older type the combustion chamber (of metal or glass) is sunk in the calorimeter proper, tubes being provided for the entrance and exit of the gaseous substances involved in the action. These tubes are generally in the form of immersed in the water of the calorimeter. In the newer type (which was first proposed by Andrews for the combustion of gases) the chemical action takes place in a completely closed combustion chamber of sufficient strength to resist the pressure generated by the sudden action, which is often of explosive violence. The steel combustion chamber is of about 250 c.c. capacity, and is wholly immersed in the calorimeter. To withstand the chemical action of the gases, the calorimetric bomb is lined either with platinum, as in Berthelots apparatus, or with porcelation, as in Mahlers. For ordinary combustions compressed oxygen is used, so that the combustible substance burns almost instantaneously, the action being induced by means of some electrical device which can be controlled from without the calorimeter. The accuracy of heats of combustion determined in the closed calorimeter is in favourable cases about one-half per cent. of the quantity estimated. 5. Units and Notation in thermochemistry The heat-units employed in thermochemistry have varied from time to time. The following are those which have been in most general use: Small calorie or gramme calorie. cal. Large or kilogramme calorie. Cal. Centuple or rational calorie. K. The centuple calorie is the amount of heat required to raise 1 g. of water from o ° C. to C., and is approximately equal to ioo cal. The large calorie is equal to 1000 cal. In view of the not very great accuracy of thermochemical measurements, the precise definition of the heat-unit employed is not a matter of special importance. It has been proposed to adopt the joule, with the symbol j, as thermochemical unit for small quantities of heat, large amounts being expressed in terms of the kilojoule, Kj =100o j. (For the exact relation between these heat-units, see Calorimetry.) For ordinary thermochemical work we may adopt the relation 1 cal. = 4.18 j, or 1 Cal. = 4.18 Kj. Except for technological purposes, thermochemical data are not referred to unit quantity of matter, but to chemical quantities i.e. to the gramme-equivalents or gramme-molecules of the reacting substances, or to some multiples of them. The notation which Julius Thomsen employed to express his thermochemical measurements is still extensively used, and is as follows: The chemical symbols of the reacting substances are written in juxtaposition and separated by commas; the whole is then enclosed in brackets and connected by the sign of equality to the number expressing the thermal effect of the action. The chemical symbols stand for quantities measured in grammes, and heat-evolution is reckoned as positive, heat-absorption as negative. Thus [S, 20] =71100 cal. indicates that 71100 calories are evolved when 32 grammes of sulphur react with 2 X 16 grammes of free oxygen to form sulphur dioxide. It is of course necessary in accurate work to state the conditions of the reaction. In the above instance the sulphur is supposed to be in the solid rhombic modification, the oxygen and sulphur dioxide being in the gaseous state, and the initial and final systems being at the ordinary temperature. Again, the equation [2N, 0] =-18500 cal. indicates that if 28 grammes of nitrogen could be made to unite directly with 16 grammes of oxygen to form nitrous oxide, the union would cause the absorption of 18500 calories. When substances in solution are dealt with, Thomsen indicates their state by affixing Aq to their symbols. Thus [NaOH Aq, HNO 3 Aq] =13680 cal. represents the heat of neutralization of one gramme-equivalent of caustic soda with nitric acid, each in dilute aqueous solution before being brought into contact. One draw back of Thomsens notation is that the nature of the final system is not indicated, although this defect in general causes no ambiguity. Berthelots notation defines both initial and final systems by giving the chemical equation for the reaction considered, the thermal effect being appended, and the state of the various substances being affixed to their formulae after brackets. W. Ostwald has proposed a modification of Berthelots method which has many advantages, and is now commonly in use. Like Berthelot, he writes the chemical equation of the reaction, but in addition he considers the chemical formula of each substance to express not only its material composition, but also the (unknown) value of its intrinsic energy. To the right-hand member of the equation he then adds the number expressing the thermal effect of the reaction, heat-evolution being as before counted positive, and heat-absorption negative. The mass-equation then becomes an energy-equation. He thus writes S+02=S02+7110o cal., which expresses the fact that the intrinsic energy of the quantities of sulphur and oxygen considered exceeds that of the sulphur dioxide derived from them by 71100 cal. when thermal units are employed. The equation H2+12=2HI-12200 cal. expresses that under certain conditions the intrinsic energy of hydriodic acid is greater than the intrinsic energy of its component elements by 12200 cal., i.e. that hydriodic acid is formed from its elements with absorption of this amount of heat. Energyequations, such as the above, may be operated with precisely as if they were algebraic equations, a property which is of great advantage in calculation. Thus by transposition we may write the last equation as follows 2HI =H2+12+12200 cal., and thus express that hydriodic acid when decomposed into its elements evolves 12200 cal. for the quantity indicated by the equation. Ostwald has made the further proposal that the formulae of solids should be printed in heavy type (or within square brackets), of liquids (solutions, c.) in ordinary type, and of gases in italics (or within curved brackets), so that the physical state the substances might be indicated by the equation itself. Thus the equation Cl 2 -1-2KI, Aq=2KC1, Aq+12+52400 cal., or (C12) +2KI, Aq =2KC1, Aq+[12]-I-52400 cal., would express that when gaseous chlorine acts on a solution of potassium iodide, with separation of solid iodine, 52400 calories are evolved. 6. Heat of Formation. For thermochemical calculations it is of great importance to know the heat of formation of compounds from their elements, even when the combination cannot be brought about directly. As an example of the use of Ostwalds energy-equations for the indirect determination we may take the case of carbon monoxide. The following equations give the result of direct experiment  :- C +20 = CO 2+943 oo cal. CO+ O=CO 2 +68000 cal. If now it is required to find the heat of formation of the compound CO, which cannot be directly ascertained, we have merely to subtract the second equation from the first, each symbol representing constant intrinsic energy, and thus we obtain C+0 00= 26300 cal., or C+0=C0+26300 cal., that is, the heat of formation of a gramme-molecule of carbon monoxide is 26300 cal. As has already been stated, the heat of formation of a compound is the amount (expressed in thermal units) by which its intrinsic energy exceeds or falls short of that of the elements which enter into its composition. Now of the absolute values of intrinsic energy we know nothing; we can only estimate differences of intrinsic energy when one system is compared with another into which it may be directly or indirectly converted. But since the elements cannot be converted one into the other, we are absolutely without knowledge of the relative values of their intrinsic energy. This being the case, we are at liberty to make the assumption that the intrinsic energy of each element (under specified conditions) is zero, without thereby introducing any risk of self-contradiction in thermochemical calculations. This assumption has the great advantage, that the intrinsic energy of a compound relatively to its elements now appears as the heat of formation of the compound with its sign reversed. Thus if we consider the energyequation C +02 = CO 2+943 00 cal., and replace the symbols by the values of the intrinsic energy, viz. zero for carbon and oxygen, and x for carbon dioxide, we obtain the equation o+o=x+94300 cal. or x = 94300 cal. With knowledge then of the heats of formation of the substances involved in any chemical action, we can at once calculate the thermal effect of the action, by placing for each compound in the energy-equation its heat of formation with the sign reversed, i.e. its heat of decomposition into its elements. Thus if we wish to ascertain the thermal effect of the action Mg+CaO =MgO+Ca, we may write, knowing the heats of formation of CaO and Mg0 to be 131000 and 146000 respectively, 0-131000 = 0-146000+x x =15000 cal. Since heats of formation afford such convenient data for calculation on the above method, they have been ascertained for as many compounds as possible. Substances with positive heats of formation are termed exothermic; those with negative heats of formation are termed endothermic. The latter, which are not very numerous, give out heat on decomposition into their elements, and are more or less unstable. Amongst endothermic compounds may be noted hydriodic acid, HI, acetylene, C 2 H 2, nitrous oxide, N 2 O, nitric oxide, NO, azoimide, N 3 H, nitrogen trichloride, NC1 3. Some of these pass into their elements with explosive violence, owing to the heat generated by their decomposition and the gaseous nature of the products. 7. Heat of Combustion The thermochemical magnitude which is universally determined for organic compounds is the heat of combustion, usually by means of the calorimetric bomb. The relation between the heat of combustion of a hydrocarbon and its heat of formation may be readily seen from the following example. The hydrocarbon methane, CH 4, when completely burned to carbon dioxide and water, generates 213800 cal. We may therefore write CH 4 +40 = C02+2H20+213800. Now we know the heats of formation of carbon dioxide (from diamond) and of liquid water to be 94300 cal. and 68300 cal. respectively. The above equation may consequently be written, if x is the heat of formation of methane, -x+0 = -94300-(2 X 68300) +213800 x =17000 cal. This heat of formation, like that of most hydrocarbons, is comparatively small: the heat of formation of saturated hydrocarbons is always positive, but the heat of formation of unsaturated hydrocarbons is frequently negative. or example, ethylene, C2H4 j is formed with absorption of 16200 cal., acetylene, C 2 H 2, with absorption of 59100 cal., and liquid benzene, C 6 H 6, with absorption of 9100 cal. Since the heat of combustion of a hydrocarbon is equal to the heat of combustion of the carbon and hydrogen it contains minus its heat of formation, those hydrocarbons with positive heat of formation generate less heat on burning than the elements from which they were formed, whilst those with a negative heat of formation generate more. Thus the heat generated by the combustion of acetylene, C 2 H 2, is 316000 cal., whereas the heat of combustion of the carbon and hydrogen composing it is only 256900 cal., the difference being equal to the negative heat of formation of the acetylene. For substances consisting of carbon, hydrogen and oxygen, a rule was early devised for the purpose of roughly calculating their heat of combustion (J. J. Welters rule). The oxygen contained in the compound was deducted, together with the equivalent amount of hydrogen, and the heat of combustion of the compound was then taken to be equal to the heats of combustion of the elements in the residue. That the rule is not very accurate may be seen from the following example. Cane-sugar has the formula C12H22011. According to Welters rule, we deduct II 0 with the equivalent amount of hydrogen, namely, 22 H, and are left with the residue 12 C, the heat of combustion of which is 1131600 cal. The observed heat of combustion of sugar is, however, 1354000, so that the error of the rule is here 20 per cent. A much better approximation to the heat of combustion of such substances is obtained by deducting the oxygen together with the amount of carbon necessary to form C02, and then ascertaining the amount of heat produced by the residual carbon and hydrogen. In the above case we should deduct with II 0 the equivalent amount of carbon 5.5 C, thus obtaining the residue 6.5 C and 22 H. These when burnt would yield (6.5 X9430o)+(II X68300) =1364250 cal., an amount which is less than 1 per cent. different from the observed heat of combustion of sugar. Neither of the above rules can be applied to carbon compounds containing nitrogen 8. Heat of Neutralization It has already been stated that the heats of neutralization of acids and bases in aqueous solution are additively composed of two terms, one being constant for a given base, the other constant for a given acid. In addition to this, the further regularity has been observed that when the powerful monobasic acids are neutralized by the powerful monacid bases, the heat of neutralization is in all cases the same. The following table gives the heats of neutralization of the commoner strong monobasic acids with soda: Hydrobromic acid Hydriodic acid Nitric acid Chloric acid Bromic acid Within the error of experiment these numbers are identical. It was at one time thought that the greater the heat of neutralization of an acid with a given base, the greater was the strength of the acid. It is now known, however, that when weak acids or bases are used, the heat of neutralization may be either greater or less than the normal value for powerful acids and bases, so that there is no proportionality, or even parallelism, between the strengths of acids and their heats of neutralization . sodium carbonate- Na 2 CO 3.. .

Heat of Solution When substances readily combine with water to form hydrates, the heat of solution in water is usually positive; when, on the other hand, they do not readily form hydrates, or when they are already hydrated, the heat of solution is usually negative. The following examples show the effect of hydration on heat of solution in a large quantity of water: io. Application of the Second Law thermodynamics to Thermochemistry. What is commonly understood by thermochemistry is based entirely on the first law of thermodynamics, but of recent years great progress has been made in the study of chemical equillibrium by the application of the second law.
