How World War II Affected Women

Womens lives changed in many ways during World War II. As with most wars, many women found their roles and opportunities—and responsibilities—expanded. As Doris Weatherford wrote, â€Å"War holds many ironies, and among them is its liberating effect on women.† But the war also results in the special degradation of women, as victims of sexual violence. Around the World While many of the resources on this topic address American women specifically, Americans were by no means unique in being affected by and  playing critical roles in the war. Women in other Allied and Axis countries were also affected. Some ways in which women were affected were specific and unusual: the comfort women of China and Korea and the extermination and suffering of Jewish women in the Holocaust, for example. Women were among those held in internment camps by the United States for being of Japanese descent. Women and the Holocaustâ€Å"Comfort Women: of China and KoreaMargaret Bourke-White Photographs including of concentration and work campsJapanese Internment in the U.S. In other ways, there were similar or parallel global experiences: the advent of British, Soviet, and American women pilots or the worldwide home-makers burden of coping with wartime rationing and shortages, for example. American Women at Home and Work Husbands went to war or went to work in factories in other parts of the country, and the wives had to pick up their husbands responsibilities. With fewer men in the workforce, women filled more traditionally male jobs.

American Women and the Military In the military, women were excluded from combat duty, so women were called on to fill some military jobs that men had performed, to free men for combat duty. Some of those jobs took women near or into combat zones, and sometimes combat came to civilian areas, so some women died.  Special divisions for women were created in most of the military branches.

Thomas Paine A Very Curious Individual - 1664 Words

Thomas Paine (1737-1809) was a very curious individual. An Englishman who became a champion of the rights of man and free humanity around the globe, he is generally regarded as one of the Founding Fathers of the United States, irrespective of the fact that he held no political office and seems to have been somewhat glossed over (if not altogether ignored) by many of the ‘confirmed’ Founders. John Adams, for instance, is said to have pooh-poohed the writings of the troublesome Paine, even growing to hate him in his old age. Said Adams of Paine: â€Å"He is a keen writer [but his most incendiary work, Common Sense (1776), was no more than] a tolerable Summary of the Arguments which I had been repeating again and again in Congress for nine months.† Towards the end of his life, Adams grew harsher in his opinion of Paine, calling Common Sense â€Å"a poor, ignorant, Malicious, short-sighted, Crapulous Mass.† Partly owing to statements like this, Paine is regar ded by many, especially in academia and politics, as a â€Å"lesser founder.† Despite this, his contributions to the Revolutionary cause cannot be overstated. Even Adams had to admit: â€Å"Without the pen of the author of ‘Common Sense,’ the sword of Washington would have been raised in vain.† Washington himself is said to have ordered the following passage from Paine’s essay, â€Å"The Crisis†, to be read by his troops on the eve of their crossing the Delaware to launch a surprise attack on Trenton in December, 1776: â€Å"These are the times thatShow MoreRelatedTriple Bottom Line10664 Words   |  43 PagesAccountAbility coined and began using the term in its work.* The term found public currency with the 1997 publication of the British edition of John Elkington s Cannibals With Forks: The Triple Bottom Line ofUst Century Business. ^ There are in fact very few references to the term before this date, and many (including the man himsel f) claim that Elkington coined it.

Effects of Autism Free Essays

AUTISM ESSAY Name:Cloleisha Ottey Group:M1 Date:April 11, 2013 Lecturer:Miss. M. East Assignment:Three Autism and its Effects Autism is a syndrome characterized by issues in communication and social interaction and is diagnosed at the latest three years in a child’s life. We will write a custom essay sample on Effects of Autism or any similar topic only for you Order Now Autism is also called Autism Spectrum Disorder (ASD) and includes a broad range of disabilities such as Asperger Syndrome, Rett’s Syndrome (almost exclusively affects females) and Pervasive Development Disorder. There are varying degrees of the disorder from low-functioning (no communication) to high-functioning (some communication and inappropriate but existent social skills). The characteristics also vary and present themselves socially (resistance to being held or touched), linguistically (makes verbal sounds while listening-echolalia), behaviorally (obsessions with objects, ideas or desires. ), emotionally (resists change in the environment (people, places, objects). ) and physically (unusual gait. ) in the child’s life. With an individual dealing with so much, how does it affect the family structure? I will be exploring the implications of the effects of Autism for the individual, parents and siblings. The life of an Autistic child is overwhelming. Carly a fourteen year old, when she was finally able to communicate in a way the world could understand expressed what it feels like being Autistic. After eleven years of silence she ran up to a computer and entered her first word â€Å"hurt†, her second word was â€Å"help†. She expressed how much she would love to be like other children but she can’t help but be herself. She explained the reason for her constant rocking, not wanting to be touched and banging her head. She said it felt like a thousand ants were crawling over her body, her feet felt like they were on fire and if she didn’t bang her head she felt like she would explode. For years she understood what was being said around/about her but had no way of expressing herself. Autistic children, who are not able to communicate like Carly, go through this overload of sensory input that drives them nuts. Not being able to communicate to their parents that the sound is too loud, or the light is too bright becomes frustrating. They are treated as if they are dumb and do not understand what is being said when that is far from the truth. Many children who have been diagnosed as being Autistic have been found to be dual exceptional, which means having a disability but are also being a gifted child. One of the most difficult things a parent can experience is not being able to understand what their child needs. Raising a child who does not speak or express themselves in a way you can understand is heart wrenching, especially when they are experiencing pain and you do not know where it hurts or what the symptoms are-helplessness is painful. Not knowing why they hurt themselves, scream, pull away when you touch them or say the things they say. However, parents must remember that, despite the diagnosis their child is the same person that they have always  been. The only difference is that they know now what condition they have and can begin to help them to maximize their potential and to live life to the fullest. Parents often feel like failures and blame themselves for the diagnosis. It is reported that 80% of marriages end in divorce when a child is diagnosed with Autism, leaving the mothers to deal with the day to day stresses of raising a child with a disability. They constantly ask â€Å"Was it that one drink? or â€Å"Was it that fall I didn’t tell anyone about? † Another implication for parents of Autistic children is the cost of care which does not come cheap. In a country like Jamaica where health care for disability cases is not predominant – it costs an arm and a leg, approximately US$40,000-$70,000 per year (as per the Autism Center of Montego Bay). Parents have to ensure that their Autis tic child gets physical, occupational and speech therapies as early intervention and lifelong therapies to improve the skills they already possess and to not lose what they have gained. Parents may feel that their child with autism takes a lot of their time and attention – siblings feel this way too. Parents often think that because their other child/children are not suffering from this diagnosis or any other major ailment and are for want of a better word â€Å"normal†- they do not need time with them. Siblings will go out of their way to be noticed by their parents by getting in trouble at school, rebelling and some are left to raise themselves. Siblings like for parents to make time for them when possible to listen to the things that are important to them. It may help to do some activities separately in the family, if you can. Parents need to find out what the child would like them to do together, make a date and keep it. While they are out let it be about the child, do not bring up the Autistic sibling. However, siblings may benefit from having time to themselves, for example occasional breaks like  sleepovers at friends’ homes. They also need to be able to bring their own friends home and enjoy themselves without interruption, where possible. Try to listen to siblings’ worries and concerns – but also their ideas. Older children may have good ideas about how best to manage certain situations. If they have a good relationship with their brother or sister, they may be able to ask them to do things that the parent can’t. The future is a concern for siblings. At some point,  it may help to talk  with them about who is expected to care for their brother or sister when they are older. There has been an increase in Autism cases, according to the Director of the Montego Bay Autism Center on April 2, 2013. To combat the rise each supporting entity (parents and siblings) must have an air of patience. The Autistic child cannot help but be who they are, so parents and siblings have to rise to the occasion and be advocates. Understanding, supporting and educating are a few of the ways to show that Autistic life – is still a life. Autism has a wide effect and often has negative implications, however, the positive implications outweigh them. Reference 1. Stanley, G. I and Tippy G. November 2, 2011.

So when you re siting through the ruts, Don t perplex your head. Flee from hatred, Mischief and green-eyed monster. Don t burry your ideas, set your vision to world. Wake up and unrecorded! Robert Nesta Marley was born in a rural parish of St. Ann in northern Jamaica at 2:30 in the forenoon of February 6th 1945. At the age of three Bob was reported to hold physic powers.

Oedipus The King Essay Example

Oedipus The King Essay Determination and Strength: An essay about Oedipus the King The play Oedipus the King by Sophocles attempts to portray Oedipus (King of Thebes) as an extremely powerful and dignified man. Throughout the play, the classic story of Oedipus comes to life and the audience comes to see that no matter how bad Oedipus life seems to get, he steadily maintains his nobility and trustworthiness. Sophocles lets the reader know in the beginning that Oedipus fate has been predetermined: that he will kill his father and marry his mother. Although Oedipus does not know this, the reader does, thus making Oedipus out to be not just a king but a person as well. Throughout the play the audience sees Oedipus power, strength, and dignity. Although Oedipus attitude changes throughout the play, we still see him as an extremely noble and trust-worthy man. The audience sees Oedipus change of character three times throughout the play. At the beginning of the play Oedipus is a great king with extreme strength, later we see him as more of a tyrant opposed to a king and lastly Oedipus demeanor changes once again to a fearful and humiliated man who maintains his dignity even at his greatest defeat. At the end however, Oedipus indeed proves himself to stay dignified. Oedipusfirst shows us to be a confident and powerful hero when he solves the riddle of the Sphinx, who has Thebes under lock and key. Despite the fact that the Sphinx threatened anyone to death who answered the riddle incorrectly, Oedipus was determined and here was when we see his bravery. After correctly solving the riddle the Sphinx frees the city of Thebes and Oedipus becomes famously known for his bravery leading him to become King of Thebes, as the people state, You cut us loose from the bloody tribute we had paid that harsh, brutal singer. We taught you nothing, no skill, no extra knowledge, still you triumphed (44-47).

Current World Population and Future Projections

Current World Population and Future Projections The world population has grown tremendously over the past 2,000 years. In 1999, the world population passed the six-billion mark. By March of 2018, the official world population had jumped over the seven-billion mark to an estimated  7.46 billion. World Population Growth Humans had been around for tens of thousands of years by the year 1 A.D. when the Earths population was an estimated 200 million. It hit the billion mark in 1804 and doubled by 1927. It doubled again in less than 50 years to four  billion in 1975. Year Population 1 200 million 1000 275 million 1500 450 million 1650 500 million 1750 700 million 1804 1 billion 1850 1.2 billion 1900 1.6 billion 1927 2 billion 1950 2.55 billion 1955 2.8 billion 1960 3 billion 1965 3.3 billion 1970 3.7 billion 1975 4 billion 1980 4.5 billion 1985 4.85 billion 1990 5.3 billion 1995 5.7 billion 1999 6 billion 2006 6.5 billion 2009 6.8 billion 2011 7 billion 2025 8 billion 2043 9 billion 2083 10 billion Concerns for an Increasing Number of People While the Earth can only support a limited number of people, the issue is not so much about space as it is a matter of resources like food and water. According to author and population expert  David Satterthwaite, the concern is about the number of consumers and the scale and nature of their consumption. Thus, the human population can generally meet its basic needs as it grows, but not at the scale of consumption that some lifestyles and cultures currently support. While data is collected on population growth, it is difficult for even sustainability professionals to understand what will happen on a global scale when the worlds population reaches 10 or 15 billion people. Overpopulation is not the biggest concern, as enough land exists. The focus would primarily be on making use of uninhabited or underpopulated land. Regardless, birth rates have been falling around the world, which may slow down population growth in the future.  As of 2017, the total fertility rate for the world was 2.5, down from 2.8 in 2002 and 5.0 in 1965, but still at a rate that allows population growth. Growth Rates Highest in Poorest Countries According to World Population Prospects: The 2017 Revision, most of the worlds population growth is in poor countries. The 47 least developed countries are expected to see their collective population nearly double from 2017s one billion to 1.9 billion by 2050. Thats thanks to a fertility rate of 4.3 per woman. Some countries continue to see their populations explode, such as Niger with a 2017 fertility rate of 6.49, Angola at 6.16, and Mali at 6.01. In contrast, the fertility rate in many developed countries was below replacement value (more loss of people than those born to replace them). As of 2017, the fertility rate in the United States was 1.87. Others include Singapore at 0.83, Macau at 0.95,  Lithuania at 1.59, the Czech Republic at 1.45, Japan at 1.41, and Canada at 1.6. According to the UN Department of Economic and Social Affairs, the worlds population has been rising at a rate of roughly 83 million people  every year, and the trend is expected to continue, even though fertility rates have been dropping in almost all regions of the world. Thats because the worlds overall fertility rate still exceeds the rate of zero population growth. The population-neutral fertility rate is estimated at 2.1 births per woman.

Assignment 6 - Essay Example The data obtained reveals that learners are gifted differently, and there is a need to attend to them based on their abilities. This provides a platform for teachers to attend to learners with special needs. Necessary assistance would be extended to such learners. Assessing this type of records would be relatively easy with the assistance from subject teachers and administrators of the school. Working closely with parents would help avail necessary documents of previous performance. The author is involved as a principal in a school in Southern Oregon characterized by transition of leadership, where he replaces a principle that left little to be desired. The school has 86% annual student transient rate with a high teacher turnover. Parents’ involvement is low, and all is left to the teachers. The principal aims to turn things around and pull the high-poverty community together. The new principal is keen to realize the key affected areas in his new school. The teachers are alienated in decision-making, and their opinions are overlooked. The learners are not addressed appropriately, and there is a case of multiage grouping. Such a decision affects the overall performance of the learners, in the long run. Cooperative learning is poorly executed leading to a great deal of â€Å"Davids† in the institutions. Another problem is full class inclusion without paying attention to gifted and learners with special needs. The author further realizes that language learning was a mystery topic. With the involvement of teachers, he engages in an action research with an aim to have things work perfectly. He designs a plan to higher new teachers for the school to meet the demands of the learners. The learners would need instructors competent enough to better them. The principal purposes to meet the key parents for their involvement. They would support teachers establish the most conducive environment in the school. He identified requirements in the new

Currently, America is the largest importer of oil from Venezuela, and China will be taking away from this amount. 2) U.S. consumers may benefit from with deal through an increase in Venezuelan oil production. As of right now, Venezuela produces about 3 billion barrels of oil each day (James 2011). With help from the Chinese loans, oil production is expected to increase to increase massively. This, in turn, will benefit U.S. consumers because the oil price should hopefully come down. With more oil on the market, prices will be driven down. The cost of gas to U.S. consumers should reduce considerably. However, the United States government needs to be careful that there are not any deals going on between the Venezuelan government and their Chinese counterparts. Energy Minister Rafael Ramirez has said, â€Å"We don’t do discounts with anyone†¦We sell at international prices (James 2011).

Higher education Essay Example | Topics and Well Written Essays - 750 words - 2

Higher education - Essay Example I agree that too many people are participating in colleges. There are several opportunities apart from going to college, and they are all viable. There are so many people going to college, and the most interesting thing is that there is a high rate of drop out compared to those graduating. The graduation rate is low as described by Murray in his article. It is evidential that there are six months certificates, which are flexible as compared to four years, stay in college. In addition, most of the students spend up to six years in college; they could have invested the time in more viable ventures. Not all people that go to the college become successful. At the same time, too many people are joining the colleges leading the current education system into shamble (Murray 225). According to statistics, from the financial institutions, the competence of the financial students is wanting. Most of the people have tried to be fit and conform to the social norms of the society. No one is bound to fit into the social norm of the society, in fact, they must use creative and critical thinking does decide if to join the college or to become an electrician. The fact that too many people are going to college does not affect or influence an individual’s decision of joining the college. Joining the college must not me a communal decision but a personal decision (Murray 230). It is important to note that, not everyone who can make it through to college. Most of the skills must be learned in the alimentary and middle school. Murray describes the education system as a failing strategy. Most of the people in the society believe that everyone in the society must have a bachelor’s degree to be considered in the job market. People must do what they are good at and not what the society tells them to do. Money is not the reason for joining the college but getting a

Factor Language Model Programming

Factor Language Model Programming Language Model Language model helps a speech recognizer figure out how likely a word sequence is, independent of acoustics. There is a linguistic and statistical approach to calculate the probability. The linguistic technique tries to understand the syntactic and semantic structure of a language and derive the probabilities of word sequences using this knowledge. The challenge here is to have proper co occurrence statistics of the unit of recognition. The approach in use evaluates a huge text corpus in a statistical way and word transitions. Current language models make no use of the syntactic properties of natural language but rather use very simple statistics such as word co-occurrences. Recent results show that incorporating syntactic constraints in a statistical language model reduces the word error rate on a conventional dictation task by 10% [M.S.Salam, 2009]. Proposed Language Model The approach proposed here uses factored language model which incorporates the morphological knowledge. Factored language models have recently been proposed for incorporating morphological knowledge in the modeling lexicon. As suffix and compound words are the cause of the growth of the vocabulary, a logical idea is to split the words into shorter units. The language model proposed in this research is based on morphology. A morphological analyser obtains and verifies the internal structure of a given complete word form [Rosenfield, 2000]. Building a morphological analyser for highly inflecting, agglutinative languages is a challenging task. It is very difficult to build a high performance analyser for such languages. The main idea here is to divide a given word form into a stem and single suffix. Morphology plays a much greater role in Telugu. An inflected Telugu word starts with a stem and may have suffix(s) added to the right according to complex rules of saMdhi. This research proposes a new data structure based on Inverted Index and an efficient algorithm for accessing its elements. Few researchers have used tries for efficient retrieval from dictionary, earlier. This research work is different from earlier work in two ways: a) variation to the structure of trie b) the method of identifying and combining inflections. Modified Trie Structure A trie is a tree based data structure for storing strings in order to support fast pattern matching. A trie T represents the strings of set S of n strings with paths from root to the external node of T. Fig 5.1: Original Trie Structure The trie considered here is different from standard trie in two ways: 1) A standard trie does not allow a word to be prefix of another, but the proposed trie structure allows a word to be prefix of another word. The node structure and search algorithm also is given according to this new property. 2) Each word in a standard trie ends at an external node, where as in the modified trie a word may end at either an external node, or the internal node. Irrespective of whether the word ends at internal node or external node, the node stores the index of the associated word in the occurrence list. The node structure is changed such that, each node of the trie is represented by a triplet C,R,Ind>. C represents character stored at that node. R represents whether the concatenation of characters from root till that node forms a meaningful stem word. Its value is 1, if characters from root node to that node form a stem, 0 otherwise. Ind represents index of the occurrence list. Its value depends on the value of R. Its value is -1 (negative 1), if R=0, indicating it is not a valid stem. So no index of occurrence list matches with it. If R=1, its value is index of occurrence list of associated stem. Fig 5.2: Modified Trie Structure Advantages relative to binary search tree: The following are the main advantages of tries overbinary search trees(BSTs): Looking up keys is faster. Looking up a key of lengthmtakes worst caseO(m) time. A BST performs O(log(n)) comparisons of keys, wherenis the number of elements in the tree, because lookups depend on the depth of the tree, which is logarithmic in the number of keys if the tree is balanced. Hence in the worst case, a BST takes O(mlogn) time. Moreover, in the worst case log(n) will approachm. Also, the simple operations tries use during lookup, such as array indexing using a character, are fast on real machines. Tries can require less space when they contain a large number of short strings, because the keys are not stored explicitly and nodes are shared between keys with common initial subsequences. Tries facilitatinglongest-prefix matching, helping to find the key sharing the longest possible prefix of characters all unique. Corpus structure of proposed Language Model The corpus consists of the following modules: Stem word dictionary This accommodates all the stems of the language. Stem word dictionary is implemented as an Inverted Index for better efficiency. The Inverted index will have the following two data structures in it: 1) Occurrence list: It is an array of pairs, 2) Stem trie: consisting of stem words Occurrence list is constructed based on the grammar of the language, where each entry of the list contains the pair (ii) Inflection Dictionary This dictionary contains the list of all possible inflections of the Telugu language. Each entry of Stem word dictionary lists the indexes of this dictionary to indicate which all inflections are possible with that stem. The proposed corpus structure helps in reducing the corpus size drastically. Every stem word may have number of inflections possible. If the inflected words are stored as it is, then corpus size would be m*n, where m is number of stem words and n is number of inflections. Instead of storing all the inflected words, the proposed corpus structure stores stem words and inflections separately, and handles the inflected words through morphology. Hence the corpus size required is for m stem words and n inflections i.e., m+n. Thus there is a great reduction in the corpus size. For a corpus of 1000 stem words and 10 inflections, the required corpus size is 1000+10=1010, which otherwise would have required 1000*10=10000. Fig 5.3 : Corpus structure of proposed Language Model Textual Word Segmentation using Proposed Language Model The proposed language model is used to develop a textual word segmenter. A word segmenter is used to divide the given inflected word into a stem and single inflection. This is required as the corpus stores stems and inflections separately. Input the word segmenter is an Inflected word. Syllabifier takes this word and divides the word into syllables and identifies if the letter is a vowel or a consonant. After applying the rules syllabified form of the input will be obtained. Once the process of syllabification is done, this will be taken up by the analyzer. Analyzer separates the stem and inflection part of the given word. This stem word will be validated by comparing it with the stem words present in stem dictionary. If the stem word is present, then the inflection of the input word will be compared with the inflections present in inflection dictionary of the given stem word. If both the inflections get matched then it will directly displays the output otherwise it takes the appropriate inflection(s) through comparison and then displays. Syllabification is the separation of the words into syllables, where syllables are considered as phonological building blocks of words. It is dividing the word in the way of our pronunciation. The separation is marked by hyphen. In the morphological analyzer, the main objective is to divide the given word into root word and the inflection. For this, we divide the given input word into syllables and we compare the syllables with the root words and inflections to get the root word and appropriate inflection. Fig 5.4: Block diagram of Word Segmentr for text Steps for word segmentation Receiving the inflected word as an input from the user. Syllabify the input Analyze the input and validating the stem word. Identify the appropriate inflection for the given stem word by comparing the inflection of given word with the inflections present in inflection dictionary of the stem word. Displaying the appropriate inflected word. For example, considering the word â€Å"nAnnagariki† (à  Ã‚ °Ã‚ ¨Ãƒ  Ã‚ °Ã‚ ¾Ãƒ  Ã‚ °Ã‚ ¨Ãƒ  Ã‚ ±Ã‚ Ãƒ  Ã‚ °Ã‚ ¨Ãƒ  Ã‚ °-à  Ã‚ °Ã‚ ¾Ãƒ  Ã‚ °Ã‚ °Ãƒ  Ã‚ °Ã‚ ¿Ãƒ  Ã‚ °Ã¢â‚¬ ¢Ãƒ  Ã‚ °Ã‚ ¿) meaning â€Å"to father†, the input is given the user in Roman transliteration format. This input is basically divided into lexemes as: Now, the array is processed which gives the type of lexeme by applying the rules of syllabification one by one. Applying Rule 1: â€Å" No two vowels come together in Telugu literature.† The given user input does not have two vowels together. Hence this rule is satisfied by the given user input. The output after applying this rule is same as above. If the rule is not satisfied, an error message is displayed that the given input is incorrect. Now the array is: c – v – c – c – v – c – v – c – v – c – v Applying Rule 2: â€Å" Initial and final consonants in a word go with the first and last vowel respectively.† Telugu literature rarely has the words which end up with a consonant. Mostly all the Telugu words end with a vowel. So this rule does not mean the consonant that ends up with the string, but it means the last consonant in string. The application of this rule2 changes the array as following: c – v – c – c– v – c – v – c – v – c – v cv – c – c – v – c – v – c – v – cv This generated output is further processed by applying the other rules. Applying Rule 3: â€Å" VCV: The C goes with the right vowel.† The string wherever has the form of VCV, then this rule is applied by dividing it as V – CV. In the above rule the consonant is combined with the vowel, but here in this rule the consonant is combined with the right vowel and separated from the left vowel. To the output generated by the application of rule2, this rule is applied and the output will be as: cv – c – c – v – c – v – c – v – cv cv – c – c – v – cv – cv – cv This output is not yet completely syllabified, one more rule is to be applied which finishes the syllabification of the given user input word. Applying Rule 4: â€Å" Two or more Cs between Vs First C goes to the left and the rest to right.† It is the string which is in the form of VCCC*V, then according to this rule it is split as VC – CC*V. In the above output VCCV in the string can be syllabified as VC – CV. Then the output becomes: cv – c – c – v – cv – cv – cv cvc– cv – cv – cv – cv Now this output is converted to the respective consonants and vowels. Thus giving the complete syllabified form of the given user input. nAn – na –cA – ri – ku cvc – cv – cv – cv – cv Hence, for the given user input, â€Å"nAnnagAriki†, the generated syllabified form is, â€Å"nAn – na – gA – ri – ki†. Fig 5.5: Word Segmenter showing an inflected word without change in stem form Fig 5.6: Word Segmenter showing an inflected word with a change in stem form SCIL Speech Corrector for Indian Languages In inflectional language every word consists of one or several morphemes into which the word can be segmented. The approach used here aims at reducing the above mentioned problem of having a very huge corpus for good recognition accuracy. It exploits the characteristic of Telugu language that every word consists of one or several morphemes into which the word can be segmented. SCIL is a procedure To deal with complex word forms applied after recognition Using which misrecognized words are corrected Architecture of SCIL The design of Speech Corrector for Indian Languages, consists of the Syllable Identifier, Phone Sequence Generator, Word Segmenter, and Morpho- Syntactic Analyzer modules. Input speech is decoded by a normal ASR system which gives the identified word as a string. The sequence of phones would be the input to the Word Segmenter module which matches the phonetized input with the root words stored in dictionary module, and generates a possible set of root words. Morpho-Syntactic Analyzer compares the inflection part of the signal with the possible inflections list from the database and gives correct inflection. This will be given to Morph Analyzer to apply morpho-syntactic rules of the language and gives the correct inflected word. Fig 5.7: Block diagram of SCIL i) Syllable Identifier Syllable identifier marks the rough boundaries of the syllables and labels them. At this stage , we get list of syllables separated with hyphen. The user input is syllabified and this would be the input to the next module. E.g. dE-vA-la-yA-ku ii) Phone Sequence Generator As the words in the dictionary are stored at phone level transcription, this module generates the phone sequences from the syllables. E.g. d-E-v-A-l-a-y-A-k-u iii) Word Segmentor This module compares the phonetized input from starting with the root words stored in dictionary module and lists the possible set of root words. The possible root word is dEvAlayamu. iv) Dictionary Dictionary contains stems and inflections separately. It does not store inflected words as it is very difficult, if not impossible, to cover all inflected words of the language. The database consists of 2 dictionaries: Stem Dictionary Inflection Dictionary Stem dictionary contains the stem words of the language, signal information for that stem which includes the duration and location of that utterance and list of indices of inflection dictionary which are possible with that stem word. Inflection Dictionary contains the inflections of the language, signal information for that inflection which includes the duration and location of that utterance. Both the dictionaries are implemented using trie structure in order to reduce the search space. v) Morpho Syntactic Analyzer This module compares the inflection part of the signal with the possible inflections list from the database and gives correct inflection. This will be given to Morph Analyzer to apply morpho-syntactic rules of the language and gives the correct inflected word. Post Recognition Procedure Capture the utterance, an isolated inflected word. Get its syllabified form. Generate phone sequence from the syllabified word. Compare the phone sequences with stem words in the dictionary and identify the stem. Segment the word into stem and inflection. Get the list of possible inflections. Compare the inflection signals possible with that stem one by one and apply morpho-syntactic rules of the language to combine stem and inflection. Display the inflected word. Using the rules the possible set of root words are combined with possible set of inflections and the obtained results are compared with the given user input and the nearest possible root word and inflection are displayed if the given input is correct. If the given input is not correct then the inflection part of the given input word is compared with the inflections of that particular root word and identifies the nearest possible inflection and combines the root word with those identified inflections, applies sandhi rules and displays the output. When there is more than one root word or more than one inflection has minimum edit distance then the model will display all the possible options. User can choose the correct one from that. For example, when the given word is pustakaMdO (à  Ã‚ °Ã‚ ªÃƒ  Ã‚ ±Ã‚ Ãƒ  Ã‚ °Ã‚ ¸Ãƒ  Ã‚ ±Ã‚ Ãƒ  Ã‚ °Ã‚ ¤Ãƒ  Ã‚ °Ã¢â‚¬ ¢Ãƒ  Ã‚ °Ã¢â‚¬Å¡Ãƒ  Ã‚ °Ã‚ ¦Ãƒ  Ã‚ ±Ã¢â‚¬ ¹), the inflections tO making it pustakaMtO (à  Ã‚ °Ã‚ ªÃƒ  Ã‚ ±Ã‚ Ãƒ  Ã‚ °Ã‚ ¸Ãƒ  Ã‚ ±Ã‚  à  Ã‚ °Ã‚ ¤Ãƒ  Ã‚ °Ã¢â‚¬ ¢Ãƒ  Ã‚ °Ã¢â‚¬Å¡Ãƒ  Ã‚ °Ã‚ ¤Ãƒ  Ã‚ ±Ã¢â‚¬ ¹) meaning ‘with the book’ and lO making it pustakaMlO (à  Ã‚ °Ã‚ ªÃƒ  Ã‚ ±Ã‚ Ãƒ  Ã‚ °Ã‚ ¸Ãƒ  Ã‚ ±Ã‚ Ãƒ  Ã‚ °Ã‚ ¤Ãƒ  Ã‚ °Ã¢â‚¬ ¢Ãƒ  Ã‚ °Ã¢â‚¬Å¡Ãƒ  Ã‚ °Ã‚ ²Ãƒ  Ã‚ ±Ã¢â‚¬ ¹) meaning ‘in the book’) mis are possible. Present work will list both the words and user is given the option. We are working on improving this by selecting the appropriate word based on the context. SCIL Algorithm W=Utterance.wav Syl[]=SyllableIdentifier(W) Phone[]=phonetizer(Syl[]) Stem=getStem(Syl[]) Infl[]=getInflections(Stem) While (not exactMatch) word=MorphAnalyzer(stem,inflMatch) display word Stop Working of SCIL Once possible root words identified the given word is segmented into two parts, first being the root word and second part inflection. Now the inflection part is compared in the reverse direction for a match in the inflection dictionary. It will consider only the inflections that are mentioned against the possible root words, thus reducing the search space and making the algorithm faster. For example consider â€Å"nAnnagariki† (à  Ã‚ °Ã‚ ¨Ãƒ  Ã‚ °Ã‚ ¾Ãƒ  Ã‚ °Ã‚ ¨Ãƒ  Ã‚ ±Ã‚ Ãƒ  Ã‚ °Ã‚ ¨Ãƒ  Ã‚ °-à  Ã‚ °Ã‚ ¾Ãƒ  Ã‚ °Ã‚ °Ãƒ  Ã‚ °Ã‚ ¿Ãƒ  Ã‚ °Ã¢â‚¬ ¢Ãƒ  Ã‚ °Ã‚ ¿) meaning â€Å"to father†, is misrecognized as nAn-na-cA-ri-ku (à  Ã‚ °Ã‚ ¨Ãƒ  Ã‚ °Ã‚ ¾Ãƒ  Ã‚ °Ã‚ ¨Ãƒ  Ã‚ ±Ã‚ Ãƒ  Ã‚ °Ã‚ ¨Ãƒ  Ã‚ °Ã… ¡Ãƒ  Ã‚ °Ã‚ ¾Ãƒ  Ã‚ °Ã‚ °Ãƒ  Ã‚ °Ã‚ ¿Ãƒ  Ã‚ °Ã¢â‚¬ ¢Ãƒ  Ã‚ ±Ã‚ ) then SCIL is applied and will correct the recognition error as follows: The output from ASR is nAn-na-cA-ri-ku. The phone sequence generator will generate the phone sequence as n-A-n-n-a-c-A-r-i-k-u. Now, match it with the set of root words stored in dictionary module. This process will identify the possible set of root words from the Stem dictionary as follows: Once possible root words identified the given word is segmented into two parts, first being the root word and second part inflection. Now the inflection part is compared for a match in the inflection dictionary. It will consider only the inflections that are mentioned against the possible root words, thus reducing the search space and making the algorithm faster. Possible set of inflections in inflections dictionary After getting the possible set of root words and possible set of inflections they are combined with the help of SaMdhi formation rules. Here in this example cA-ri-ku is compared with the inflections of the root word nAnna After comparing it identifies gAriki as the nearest possible inflection and combines the root word with the inflection and displays the output as â€Å"nAnnagAriki†. Conclusions Language model proposed in this work results in reduction in corpus size by using factored approach. The search process is fastened by use of trie based structure. A change to standard trie is proposed. A post recognition procedure SCIL, is designed which uses the proposed language model and corrects the words misrecognized at inflections. The approach is tested using 1500 speech samples. These samples consist of 100 distinct words , each word repeated 3 times and recorded by 5 speakers in the age group 18-50. It is implemented as a speaker dependent system. An average model is built from the three utterances of each word for each speaker. Each speaker is given a unique ID, using which average model of that speaker is used for testing.

Environmental Essay -- Biodiversity, Ecological Systems

Biodiversity is the makeup and interconnectedness of ecological systems. Biodiversity makes up all the diversity among living things within a specific system. This diversity of life is invaluable to human existence for countless reasons; it is a primary source for environmental resources that shape the economics of a region, it provides the scientific community with what seems to be an ever-growing source of data that can be used for things like medicine, and provides food and aesthetic value to human life. Ontario is a privileged province of Canada as it contains over 25,00 different species of plants and animals. (†¨Lemieux, Scott. 2011) With such a vast collection of biodiversity Ontario has the obligation to ensure its protection and growth of the thousands of years of evolution that lead to the complex array of life it now contains. With the growth of the human population biodiversity is shrinking, as the globe becomes one species orientated the externalities of human exist ence threaten biodiversity. One example of these externalities are the impacts anthropogenic climate change, the changing climate due to human activities threatens wildlife as it changes their habitats at rates that most wildlife cannot adopt and evolve to live in. (Lemieux, Scott 2011). Considering the excess of 25,000 different species in Ontario, the province has a large obligation to protect and maintain this biodiversity from the dangers that human existence pose to it. The federal and provincial governments have created many laws and regulations that relate to the protection and management of the environment and biodiversity. More specifically the provincial government of Ontario has the Endangered species act, which will be the focal point of analys... ...he environment and biodiversity by protecting species at risk of extinction and their habitats. After analysis and discussion it is clearly evident that the statue was a positive movement towards a better-managed environment but has many areas of concern. The act deals with problems in a reactive nature when it should be a proactive one in maintaining biodiversity. Secondly it comes into conflict when the species concerned overlaps with private property and unjustly puts the social cost of helping the species to the hands of the private landowners, better management between landowner and government polices should be made to fix the conflicts which arise from this. Finally the act needs to deal with the scope of biodiversity being centered around a one species orientated nature, and by this should focus a better management of human interaction with the environment.

Irony in “Top of the Food Chain” by T. Coraghessan Boyle Essay

T. Coraghessan Boyle’s â€Å"On Top of the Food Chain† is more than just a narration of a selfish person’s mistakes. The narrator’s tone is a literary element used to show man’s indifference for organisms that are of no immediate benefit or are a nuisance to them. _†The thing was, we had a little problem with the insects†¦Ã¢â‚¬ _ The narrator’s tone in â€Å"Top of the Food Chain† is quickly shown as self-centered in working for his comforts and indifferent to the havoc his choices make on the environment. Humans believe that we can solve everything that is put upon us, but there is always a catch. In this story, Mother Nature proves us that she can always be ahead of how humans perceive things. From the very first sentence, the narrator is portrayed as a self-serving person. In charge of a group bringing health care to a third-world village, his choices to improve the lives of the villagers lead to wreaking chaos on the local food chain. The improvements start by poisoning the flies. When the geckos that feed off of these flies die due to starvation, the cat population also diminishes. When the cats are gone, the rat population is left unregulated and is allowed to spread disease to the humans and ruin their crops. The narrator’s condescending tone towards these disastrous events is the most significant factor that Boyle uses to develop his theme. The narrator assumes he is at the top of the food chain, and he has no problem killing off the smaller species. However, the narrator is too indifferent to realize that by hurting the lower members of the food chain, he has hurt himself. This is what shows the true irony in the story. The narrator did something that he believes is good for him, but instead it ends up being entirely the opposite of it. The story reflects that humans can do immoral things, without thinking well of the consequences and the effect it is going to have on others. â€Å"Top of the Food Chain† is ironic since Mother Nature got back at all of the selfishness that was portrayed in the story. Global Warming is a great example of how nature can get back to humans because of our own selfish actions. Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere. The release of carbon dioxide damages the atmosphere, which cause drastic changes in the climate. However, his tone following the severe circumstances that played out in the story implies that he simply does not care about anything other then what he wants. The narrator’s arrogance and belief that he can do what ever he wants without hurting himself reflects his idea that he is Top of the Food Chain. Unfortunately, he learns the hard way that his selfish actions turn around and hurt him in the end, which ends up being ironic. T. Coraghessan Boyle demonstrated us that nature can always get back to humans despite of whatever we do; selfish or unselfish.

5 More Sentences Rendered More Concise

5 More Sentences Rendered More Concise 5 More Sentences Rendered More Concise 5 More Sentences Rendered More Concise By Mark Nichol Each of the examples below illustrates a distinct strategy for shortening and simplifying sentences. A discussion and a revision follows each example. 1. You can go ahead and turn off the valve. The phrase â€Å"go ahead and† is a classic example of an extraneous phrase, preceding a verb, likely to turn up in speech when the speaker wishes to avoid seeming too assertive, but it has no place in writing, and the sentence can be further pared down by reducing it to a bare imperative statement with an implied subject: â€Å"Turn off the valve.† 2. If possible, take the rug outside and shake it to dislodge resistant dirt. Similarly, the two-step instruction in this sentence is easily truncated to a more concise direction by omitting the first verb and replacing it with the second one after the latter has been divested of the pronoun that follows it: â€Å"If possible, shake the rug outside to dislodge resistant dirt.† 3. It is not a matter of if such a risk event might occur, but more a matter of when it will occur and the organization’s preparedness to reduce the impact and proliferation of the event. The counterpoint phrases in the sentence are easily combined: â€Å"It is a matter of if, not of when, such a risk event will occur, and of the organization’s preparedness to reduce the impact and proliferation of the event.† 4. The Safe Harbor agreement was the framework used by companies in the United States and the European Union to exchange citizens’ personal data. This mechanism was declared invalid by the European Court of Justice on October 6, 2015. Simply constructed declarative statements are easily combined, usually by one of two methods- either insert one modified sentence into the other as a parenthetical, or, as here, revise both sentences so that one can be tacked onto the other: â€Å"The Safe Harbor agreement, the framework companies in the United States and the European Union used to exchange citizens’ personal data, was declared invalid by the European Court of Justice on October 6, 2015.† (Note, too, the shift from passive to active construction of the verb used. Also, the entire sentence could be rendered more active- and slightly shorter- by replacing the subject as follows: â€Å"On October 6, 2015, the European Court of Justice declared the Safe Harbor agreement, the framework companies in the United States and the European Union use to exchange citizens’ personal data, invalid.†) 5. Phorusrhacids were known as â€Å"terror birds,† and it’s clear why. They were prehistoric carnivorous birds. They were the largest flightless birds to ever walk the plant. They reached a height of up to ten feet. They were natural inhabitants of South America.   This annoyingly inelegant paragraph, written in simple, repetitive sentences as if by a child, is easily rehabilitated by employing the first method described in the previous example- incorporating a couple of the statements into the others: â€Å"Phorusrhacids, natural inhabitants of South America, are informally known as â€Å"terror birds,† and it’s clear why. These prehistoric carnivorous avians, the largest flightless birds to ever walk the plant, stood up to ten feet tall.† Find 5 more examples in this post.

Mitigation banking essays

Mitigation banking essays Now more than ever the wetlands need our help and Mitigation is the way to do it. As America expands, more and more land is used up for construction. Recently environmental protection laws designed to preserve wetlands have been seem as cumbersome and can impede on land development. To help businesses get around environmental laws and continue to build, Mitigation Banking systems have been set up to ensure no net loss of wetlands. When a company wants to destroy an area of wetlands, they are now able to purchase wetland credits from a mitigation bank or other organization that protect or restore pieces of wetland (1). The credits purchased represent an amount of wetland. The credits bought must be of equal or greater acreage than intended to be destroyed in order to insure no net loss of wetlands. The purchases wetland areas can turn up in many different ways. The credits can go towards many styles of wetlands. They can be used to restore, rehabilitate, create, or moved wetl ands. Rehabilitation is often times the most expensive as well as most difficult, but when completed will reap the largest benefits. Rehabilitated wetlands often make the best filtration for reducing contaminate levels such as phosphate. Restoration is the act of taking dry or degraded wetlands and restoring them to their natural condition by raising the water level and reestablishing dominate plants. Both contribute to creating the natural wetland that once was. There still may be a problem with restoration or rehabilitation. Often time there is extremely high levels of contaminates, so high that it does not make sense environmentally of economically to help the wetlands. In these cases the wetlands are filled in and used for construction sites. Another alternative is moving a wetland area from one area to another. These areas are easily manipulated to represent the natural wetlands almost exactly. In Tampa, Florida, Steve Dibbs successfully mov...

Supply Chain Management Apple Essay Example | Topics and Well Written Essays - 1500 words

Supply Chain Management Apple - Essay Example This success could be due to the increasing amount of supply chain managers reporting to the CEO of a company rather than to the manufacturing department, a trend across businesses (Allen, 2010). It has been suggested that the supply chain for Apple involves ten steps in four different countries, which are Singapore, Taiwan, the US and China. Taiwan provides most of the manufacturing components for an iPhone (Apple’s biggest seller []), with six different elements being produced here – the digital camera modules, international circuitry, industrial connectors, silicon Bluetooth chipset, technology printed circuit boards and stainless metal casings (Lyons, 2010). This encourages us to believe that the supply chain manager believes that Taiwan is the cheapest and most efficient supplier of many of the components for the iPhone and other Apple products. It also means that there is a bottleneck for the supply chain, in that if there were to be any economic issues or disaste rs in Taiwan, then the supply chain for the iPhone would be severely disrupted and there would be problems in the supply of these products. Essentially, the supply chain manager at Apple feels that the benefits from producing many components in Taiwan (cost and efficiency) outweigh these dangers. China is the location in which all these components come together to be assembled, suggesting that the country has a very cheap labour rate compared with the US, and the shipping costs from this country are low enough for the cost of labour in this country for this to be the most efficient method. All of this information suggests that Apple uses a vertical integration system for their Supply Chain Management (Lyons, 2010). A vertical integration system is one where most of the hardware components of a product are bought from a variety of different manufacturers which are all owned and controlled by the central company – in this case Apple. This helps to avoid any hold-up from trying to integrate many different companies, and it also stops the different pieces of hardware being used by other companies, ensuring that the end product is something completely unique – again, something very important to Apple. The use of a manufacturer owned by the central company also ensures that the data chip, or processor, or other product, can be manufactured exactly according to company specifications, ensuring a greater specificity. This can be a response to the make-buy decision. The make-buy decision The make-buy decision is essentially a choice between outsourcing and manufacturing (Probert, 1997). It has been suggested that the decision is easy, and that a company should outsource any components that are not critical to the product’s success, do not require any specialised design or manufacturing elements, and are not core to the company’s future plans and central products (Burt & Burf, 2009). There are many other ways of making the decision, one of wh ich is known as the contribution-per-constraint module (CPCM) that relies on knowing and analysing the constraints of the component (Gardiner & Blackstone, 2007). In this case, the Supply Chain Management team at Apple have decided that it is best to make many of the components (or

This makes it the largest industry in the economy. However, a growing number of supermarkets are coming under intense pressure because of unprofessional treatment meted on stakeholders in the supply chain. Tesco and other supermarkets are committed to strategic development networks that lead to increased productivity. This report gives a strategic management analysis of Tesco supermarket. ... United Kingdom is Tesco’s largest market. In this market Tesco operates under Metro, Express, Extra and Superstore banners. The retailer has diversified to non-food lines e.g. clothing. Tesco delivers close to 40,000 food products. The companies label products operate at three levels. Most of the stores contain gas stations. Therefore, it has grown to become of the leading petrol retailers in Britain. Tesco personal finance is a retailing service offered by the supermarket is a bid to expand its market share. Business environment The business environment on a retailer plays a central role in its profitability. Companies are under intense pressure to acknowledge their responsibility to the society. The introduction of taxes that target the increased advertising of fatty food is bound to affect the performance of the supermarket (Stone 2009). The relationship between consumers and supplies has also been affected because of the ‘fat tax’. The presence of powerful com petitors has led to intense price wars. In some instances, the foreign market environment is hostile and governments try to protect the local industries from foreign competition. Government policies that promote monopoly controls have been blamed for limited access to some markets and segments. Such policies have the capacity to reduce the buying power of consumers. Differentiation is increasingly becoming difficult because of unhealthy competition and government interference. Tesco has developed a policy in which it reduces the prices for fuel based on the amount of sales at its groceries. The retailer compensates by raising prices in other stores. PEST framework Political factors Besides the United Kingdom, Tesco operates in six countries in Europe. The legislative and

Hypothesis - Coursework Example se: Providing financial security for teachers is the underlying problem and the goal of the research is to identify the best approach to achieve such an objective (Brace, 2008). Therefore, the goal is to improve compensation for teachers in order to order to improve their service in teaching students. Riverdale high School aims at achieving at least 75 percent mastery among its students. This can only be achieved through an effective pay for performance system. Students Response: Data collection will involve the use of surveys and questionnaires. The data relates to the effects of the economy to the financial security of teachers. Teachers will respond to questions and field assistants will assess the living standards of teachers. Findings will be analyzed and results presented (Brace, 2008). Problem: Riverdale High School is currently overcrowded in terms of high numbers of student enrollment. There is an urgent need for a reduction in the number of students in order to reduce overcrowding. The school is also facing the problem of low pay for their teacher which has negatively affected their working morale. However, low pay for teachers has become the main problem facing the institution and this can only be addressed by devising a systematic plan. Students Response: Selection and interpretation of data will involve identifying relevant data from the survey and questionnaire. Such information will have to be related to the research problem and propose a solution. The information will also be identified as relevant based on its relation to the research hypotheses (Brace, 2008). 8) Describe how your research proves or disproves your hypothesis. In addition, list any additional research avenues created by researching the original problem. Hint: Based on an analysis of the data, the hypothesis is either supported or not supported. The question may be answered or not answered. Research can create more research while the process remains never-ending. Students

Continuous devastation Essay Example for Free

Continuous devastation Essay The story of a jellyfish in Quinn’s book represents quite an original psycho-philosophical approach to the problem of evolution. The story is made up in a form of a dialogue. A person, telling a story argues, that man is a highpoint of evolution, and the opponent applies something like a doctrine of relativity, explaining, that the world has not always been made for man and it can be ascertained, that once the world will be made for someone else again. For the speaker, evolution has finished as man appeared, because there is no more way to evolve, thusly, he advocates a theory of extremity of evolution. And while man is a final product of evolution, he can be mentioned as ultimate and supreme creature and the whole world is made for him. To contest such a conclusion the opponent turns to a relativistic approach, trying to concretize the concerned time. A jellyfish serves as example of such relativity, because in case a researcher appeared on the shore of an ocean 500 million years ago, he would find nothing more perfect, than a jellyfish on earth. Therefore, a jellyfish could reasonably believe, that it is a supreme creature, because man was just to appear and has not yet become factual. The evolution ended with jellyfish and the world was made for jellyfish. For Quinn, the core difference between jellyfish and man in the matter of evolution is that a jellyfish does not tell stories, and a man does. Therefore, he invented a religious dogma to justify his superiority and to prove, that the evolution indeed ended with man. Nevertheless, religions remain human inventions and can serve as justification only for other humans. The conclusion is quite pessimistic for humanity: once there can appear a creature, which overpasses man just as we overpass a jellyfish. Question 2 It should first be pointed, that Ishmael sees agriculture as violation of natural laws. Humans do not listen to the voice of mother-nature which tells â€Å"take what you need and leave the rest†. In spite of doing so, man starts producing surpluses, taking more, than he needs. Production of surpluses leas to expansion of population in proportion to food supplies and is not limited by any cultural or technological barriers, finally resulting in environmental and natural phenomena, which limit population growth. Quinn compares such processes to a system of checks and balances. Women’s fertility in the regions with high surpluses production lessens year after year, until it falls below reproduction rate. Quinn suggests, that population still continues to grow globally, although population may fall locally, and this depends on the type of society. Industrial societies are much less reproductive, since people have less incentive for reproduction. Agrarian societies and their members need a lot of children, often just of economic reasons, because children are future working force. For Quinn there is one positive effect from present model of population growth. This is unsustainable pressure on nature and biosphere, leading to extension of about 200 species daily. The situation is especially dramatic in non-European countries, where industrialization, combined with traditionally high birth rates, would lead to catastrophic increase of pressure on nature. Question 3 The next link between food supplies and population growth, which is proposed by Quinn is embodied in term â€Å"food race†. He compares such a race with the arms race during the Cold war. For him, human population is determined by food supplies just as with any other animals. In case food supplies grow – population and civilization grow. Sometimes the inverse relationship is possible and food supplies grow as the population grows. Consequently, there are two variables: population and food supplies, which are mutually dependant. The primary difference with the Malthusian catastrophe concept is that fro Quinn, population can never exceed it’s food supplies. It will just not grow big enough to consume more food, than it produces. Quinn himself explained, that the problem of Malthus is that â€Å"How are we going to feed those people? †, and his problem is â€Å"How are we going to stop producing all those people? †. So, Quinn saw population growth as function of food supplies with direct correlation between them. Under his concept, a population merely can not overgrow it’s food supplies, because more people are going to produce more food. Nevertheless, it can be pointed, that Quinn does not consider secondary factors, for example, ability of the Planet itself to produce enough food. Quinn believes, that there can be two endings for food race – either abandonment, or catastrophe. It is therefore up to human discretion whether to sensually stop reproduction or face overpopulation and finally decline. Question 4 Quinn defined two major types of humans dependently on their attitude to nature – Takers and Peacekeepers. Takers are those, who are usually referred as civilized. Their culture came to the world with the beginning of agricultural revolution 10 000 years ago. Takers considered themselves the masters of nature, for whom the world has been created, and so man has a right to conquer the world. They think, that the world belongs to man. The reverse of their ideas is a belief, that there is something fundamentally wrong with people. Man does not know how to live properly because that knowledge is unobtainable and related to some divine revelation. Peacekeepers, named Leavers by Quinn represent a pretty different approach. They consider themselves just a part of Nature and try to limit their influence on it by taking nothing more than they need from their environment. They think, that a man belongs to world. Quinn uses an example of Cain and Abel. Cain symbolizes ancient tribes of farmers, who already acted as takers, and Abel presents prehistoric tribes of Semite herders. Undoubtedly, herders have much smaller influence on nature, since they do nothing to change it. Killing Able by Cain, therefore, is s Symbol of Taker’s victory over Leavers. Takers indeed easily overcome the Leavers in the process of evolution, because they enjoy much greater opportunities to increase their food supplies and consequently the population. However, in the remote prospective, their way leads to disaster due to overpressure on nature. The Leaver’s approach is more respective to nature and allows to retain it for longer time, so prospectively the Leaver’s idea seems to be preferential. Question 5 Quinn uses a figure of a pedaling airman and an aircraft as a civilization metaphor. He speaks, that humans in the last several thousands of years are Takers, â€Å"who are in the air, but not in the flight†. He compares a modern taking man to a person, who has brought some flying machine to a top of a cliff and attempts to fly. For some time he could really think, that he is able to fly, because his apparatus does not longer stand on the top of a cliff, and a man finds himself in the air. However, only a little time later a man discovers, that he flies down towards his death. Under Quinn, this happens, because man is not familiar with natural laws. He looks like an inventor, who attempts to fly without knowledge of laws of aerodynamics. Similarly, humanity, which is not aware of natural laws is likely to fall down. The basic mistake of a man is that he believes, that it is he, who pilots the aircraft, although it is piloted only by natural laws. Not having a sufficient instrument to make his machine fly, man looks like a pedaling pilot, who tries to move his plane by means of bicycle pedals. It is obvious, that pedals are not good enough to bring an aircraft into motion, so man falls down. Such fall is a direct result of Taker’ conviction, that the world is made for man. Many humans just ca not believe, that their effort to pilot such a strange aircraft would lead them only to death and annihilation. Question 6 The poster, which is observed by the character of a story puts forth one of the key questions of Quinn’s book. Gorilla here is likely to represent those other creations of nature, which share our planet with us, humans. It is impossible to say whether they should be reviewed separately from nature, Separation is human feature, and gorilla’s never tried to oppose natural processes. So, they can both be regarded as nature itself and as inhabitants of that nature. The first part of a slogan: â€Å"With Gorilla gone, will there be hope for man† is more or less clear. Quinn points, that continuous devastation of nature would lead to devastation of man, who can not survive without nature. The second part: â€Å"With man gone, will there be hope for Gorilla† is less obvious. It can seem, that in case humanity died out, natural balance would be restored. In other words, gorilla does not need man to survive. To answer the question we should consider, that finally a man is also a part of nature, same as gorilla is, so distinguishing of man would also violate natural balance. Therefore, destroying humanity to save nature appears to be an extreme, same as extreme of human’s supreme power over nature. So, humans need to find a third way – a way of clever cooperation with nature. They need to once again become part of the world and be in a way similar to gorillas.

Sophocles Antigone - Creons Mistakes :: Antigone essays

Creon's Mistakes in Antigone In the awe-inspiring play of Antigone, Sophocles introduces two remarkable characters, Antigone and Creon. A conflict between these two obstinate characters leads to fatal consequences for themselves and their kindred. The firm stances of Creon and Antigone stem from two great imperatives: his loyalty to the state and her dedication to her family, her religion but most of all her conscience. The identity of the tragic hero of this play is still heavily debated. This tragedy could have been prevented if it had not been for Creon's pitiful mistakes. Creon's character possesses an infinite number of glitches in his personality, but his excessive pride was the root of his problems. His pride leads him to make accusations, before he considers the wise advice of others. Creon's pride also fills him not just as a king superior to the Gods, but also a man superior to women. The issue of Antigone being condemned to die becomes more than just a person who disobeys Creon; instead, the punishment is given even more eagerly, because it is a woman who disobeys a man. Creon's intelligent son warns Creon the people of Thebes sympathize with Antigone, but Creon accuses Haemon of being a "woman's slave" (line 756). Even though he is suppose to be loyal to the state and her citizens, he defensively questions if "the town [is] to tell [him] how [he] ought to rule?"(Line 734)The Theban king is too prideful to obey even the wisest of prophets, blind Teresias, insisting that "the whole crew of seers are money-mad" (line 1055). C reon finally puts his pride aside and listens to the Chorus' wise advice. It is difficult even then, and he obeys only because he fears the punishment that he might receive. "To yield [for Creon] is terrible" (line 1095) meaning to swallow his pride and admit that he is wrong is a very difficult thing for him to do. When Creon loses his wife and son, Creon's pride disappears, and he admits that he made a terrible mistake by not listening to anyone's advice. Antigone, a resolute and heroic female protagonist, pits her individual free will against the intractable forces of fate and against the irrational and unjust laws of tyrannical man like Creon.

Marry Shelley :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Mary Wollstonecraft Shelley was born on August 30, 1797, in London, England. She was destined to live an extraordinary life. Her parents were two of the most noted freethinkers of the Enlightenment era. Her father, William Godwin, was a celebrated philosopher and historian. He was known for overeating and borrowing money who would give him a loan. He didn’t have much time for anything but his philosophical ideas. He met his match in Mary Wollstonecraft, Mary’s mother. She was every bit as much a radical thinker as Godwin. She declared herself independent at the age of 21. She and her sisters ran a school in France, where she had an affair with an army captain and had her first child, Fanny, out of wedlock. After being abandoned, she and Fanny moved back to England and attempted suicide. She began writing. She was well-known for her revolutionary feminist writings. Wollstonecraft and Godwin met a dinner party at Godwin’s home and the two began an affair. Wollstonecraft was five months pregnant when she married Godwin. Although Godwin and Wollstonecraft didn’t agree with the whole marriage thing, they wanted Mary’s children to be legitimate children. Mary’s mother died of complications just ten days after Mary was born. Her father was a self-absorbed intellectual and was left to take care of his daughters all alone. Although he loved his daughters, the responsibility of raising them on his own was too much for him and soon began looking for a wife.   Ã‚  Ã‚  Ã‚  Ã‚  Godwin married four years later to Mary Jane Clairmont. She turned out to be a mean and shallow woman who favored her own two children over Mary and Fanny. Mary was a lively child and was often treated unfairly by her stepmother. She received frequent whippings which led to her rebellion of a girl’s traditional role. As a result of this, Mary kept to herself and was unhappy and alone. Although she didn’t have a formal education, she picked up on the intellectual environment created by her father and his visitors. Mary was quite bright and began reading the writings of her mother around the age of eight. She had memorized every word by the age of ten. Mary spent many hours at her favorite reading spot, her mother’s grave.   Ã‚  Ã‚  Ã‚  Ã‚  Percy Shelley, a poet, was an admirer and friend of William Godwin and spent a great deal of time at the Godwin house. Shelley also admired the writings of Mary’s mother.

Scheduling, Resources, and Budgeting

The aspect of addressing multiproject is indeed complicated due to the numerous tasks and concerns that are associated in the general assignment. Among these complex tasks and concerns are the resources and materials needs, the time available for the multiproject, the jobs necessary for the completion of the project, and the processes involved in each respective task involved. For the effective management of these critical procedures and concerns, it is important to have a systematic plan, which involves a schedule and a reliable budget. The development of schedule organizes the time involved and the complex procedures of the project while the budgeting concern addresses the critical resources important for the project completion. Indeed, through having a project plan, the complex nature of multiproject can be properly addressed thus, achieving the desired result for the project. For the concern of the management of the resources in the project plan, budgeting and scheduling this element is necessary for the continuous operation towards the completion of the project tasks. In this aspect, the organizer must familiarize him or herself regarding the resources needed, their access towards acquiring these, and most importantly their availability. Based on these factors, the resources must be properly scheduled to the general project plan thus, developing the connection between the task involved in the project and the resources needed for these procedures. Naturally, numerous problems are likely to arise regarding the resource access and allocation in the procedural operation for multiproject such as the inavailability some of the resources, the delayed arrival of it, insufficient acquisition, unbalanced distribution, and others. To address these problems, it is important to schedule resources highlighting the amount, availability, and the period of access of the resources needed for the project. Another important concern in resource schedule is relating them to the general project plan particularly on the organization of the procedural tasks and process steps. This is critically necessary as the resources or materials are critically important for the procedural tasks wherein the latter cannot be done with the necessary materials for it. As such, the organizer of the plan must plan the access and availability of the resources taking advantage of their abundance and resorting to other channels to alleviate shortage and inavailability. Planning ahead of these negative consequences and the period when the materials are needed can ensure the continuous establishment of the project process towards its completion. On the other hand, another critical element in the project plan is the work force required for the completion of the process tasks of the multiproject. Having the resource on time is important yet, these must still be converted to what the multiproject requires through working on it. Naturally, project work requires the elements of time and manpower thus, are essential to the completion of the project. Often, these elements also become the primary hindrances in the project completion such as the inavailability of work force, the depletion of the time allowed for the project due to the complexity of each tasks. As such, outsourcing project work is indeed practical and likewise important for the successful completion of the multiproject. Outsourcing project work can be manifested in different forms depending on the nature of the external contribution and the tasks involved. Project organizer can resort to buying already made materials that tailors to the need of the project tasks thus, minimal processing is needed allowing more time for the other procedures. Outsourcing project work can likewise come in the form of having additional people to work in the project tasks to hasten its processing over its complexity. Another is utilizing the benefits offered by the sources and producers of the materials such as their delivery, their custom parts, special requests on the products and others. All of which are indeed beneficial to the project plan as each significantly contribution towards the completion of the multiproject. Indeed, outsourcing project work is both practical and beneficial to the project as this approach saves time, gives additional work force for the project tasks, and negates the adversity of complex procedures thus, it must also be considered and incorporated in the general project plan.

Trying Juviniles As Adults Essays - Criminology, Juvenile Court

Trying Juviniles As Adults Essays - Criminology, Juvenile Court Trying Juviniles As Adults Trying Juveniles as Adults and Placing them into Adult Institutions Juveniles being tried as adults, who is to blame? In todays society it is not who or whom it is what. Juvenile offenders are now facing a double-edged sword. Not only can they be tried in a Juvenile court for a crime committed. They are now being charged as adults. Charging a juvenile as an adult has stirred up many different views. When should we say enough is enough? Violent crimes committed by juveniles have become a growing epidemic. The children of today are subjected to violence in popular songs, television shows, and even computer games. Parents having guns accessible to children and the society the child lives in all play a part in the destruction of our youth. Juvenile offenders are now facing tougher punishment for their actions. Juvenile crime is stated as an act committed by a minor that would be considered a crime committed by an adult, such as vandalism, burglary, assault, or murder (Silverstein 11). Juveniles are committing these crimes against families, classmates, and strangers. In many states, a juvenile is any one under the age of eighteen. Young offenders commit these crimes because they feel neglected, that no one cares, and this is a way to get attention. However, professionals say that juvenile offenders commit these crimes due to being abused or even ignored as a child (Valentine). Telling a parent to not ignore, punish, or leave your child home alone or your child could grow to become a criminal, seems severe. Why dont we just tell them how to raise their children? We as a society can not place the blame on a parent the juveniles are the ones at fault. Juvenile crime is dated as far back as the 1600s. Where in the Massachusetts colony, a teenager over sixteen years of age who had cursed at or hit his parents could receive the death penalty (Landau 88). In this time-period, this seemed to be a severe punishment. However, surely it made teenagers think about their actions before acting on them. In the 1880s, immigrants were the source of juvenile crime. Young immigrants were faced with many cultural differences that led them to crimes. Young Immigrant families were starving therefore stealing was their major crime (Landau 89). The juvenile justice system was condemned by society in the 1960s (Landau 89). This would show the first signs of serious juvenile offenders receiving lesser sentences than juveniles who committed minor crimes would. There is no national juvenile justice system in the United States (Landau 90). Each states law on juvenile violence varies. Juvenile crime went on the rise in the 1980-1990s. Murder has been the leading felony among juveniles. However, in 1994, 60% of juvenile offenders who committed murder were African American black men (Silverstein 12). Our legal system has two different court systems. One, Juvenile court is where we hear a lot of our cases on custody battles, child support payments, and even misdemeanors committed by juveniles. Secondly, Adult courts other wise known as Criminal court. This is where adults find out their fate for a crime committed against another. Juvenile Offenders could be tried in both systems. In some cases the prosecutor can file them directly into criminal court. This process is called concurrent jurisdiction. States have another form called statutory exclusion meaning that if the crime committed is serious enough the juvenile will automatically is tried as an adult (Hunzeker). The Juvenile system seemed to be the answer. However, it had flaws. Juvenile offenders are protected from society. The accused does not receive a criminal record for crimes committed. This results in a problem for judges and repeat offenders. If there is no record of their crimes, how will they do the time (Landau 90)? Small portions of cases do not even make it to court (Landau 90). Juvenile offenders are set free for crimes that adults get life in prison. If we set an example like that juvenile violence will continue to rise. Victims are the ones who are suffering. With the inconsistencies of the Juvenile system, a young offender could walk which would be more traumatic for the victim than the crime

Free Essays on Queen Nefertiti

The mystery of a Queen How is it possible for one of the most powerful queens of Egypt to disappear with out a trace? Egypt started out as a river valley civilization located on the Nile River. The first settlements in Egypt were around 5000 B.C.E. Amenhotet IV was the pharaoh that ruled Egypt, and then he changed his name to Akhenaten. He then proceeded to create one god for the Egyptian people to follow. Aten was the name of the god that Akhenaten created. He was trying to change Egypt into a monotheistic society. Nefertiti lived a very sketchy life, nothing is really known about Nefertiti except she married the Pharaoh Akhenaten who ruled from 1352 B.C. until 1336 B.C. Nefertiti all of a sudden vanished from the Egyptian history records. Dr. Joann Fletcher is trying to find the body of the long lost queen. There are many theories and assumptions of what might have actually happened to Nefertiti. The truth is we may never know what actually happened to her. Nefertiti and her husband were in the process of trying to change Egypt into a monotheistic country, Egyptologists believe that they would have gained many powerful enemies. Some experts also believe that Nefertiti may have also died in a plague. Some Egyptologists think that around the twelfth year of Akhenaten’s rule Nefertiti may have become his co-regent and after his death she may have ruled for a short time. After Nefertiti and Akhenaten perished there names were erased from the historic records of Egypt. Did Nefertiti die if natural causes or was she brutally murdered? This is a mystery that may never be solved. That’s why Dr. Joann Fletcher is trying to find the body of Nefertiti to see if she can solve the mystery. Nefertiti means â€Å"perfect† or the â€Å"beautiful one.† In 1912 German archeologists found three unidentified bodies.

How Biobutanol Can Be Used as a Motor Fuel

How Biobutanol Can Be Used as a Motor Fuel Biobutanol is four-carbon alcohol derived from the fermentation of biomass. When it is produced from petroleum-based feedstocks, its commonly called butanol. Biobutanol is in the same family as other commonly known alcohols, namely single-carbon methanol, and the more-well-known two-carbon alcohol ethanol. The importance of the number of carbon atoms in any given molecule of alcohol is directly related to the energy content of that particular molecule. The more carbon atoms present, especially in a long carbon-to-carbon bond chains, the denser in energy the alcohol is. Breakthroughs in biobutanol processing methods, namely the discovery and development of genetically modified microorganisms, has set the stage for biobutanol to surpass ethanol as a renewable fuel. Once considered usable only as an industrial solvent and chemical feedstock, biobutanol shows great promise as a motor fuel due to its favorable energy density, and it returns better fuel economy and is considered a superior motor fuel (when compared to ethanol). Biobutanol Production Biobutanol is derived mainly from the fermentation of the sugars in organic feedstocks (biomass). Historically, up until about the mid-50s, biobutanol was fermented from simple sugars in a process that produced acetone and ethanol, in addition to the butanol component. The process is known as ABE (Acetone Butanol Ethanol) and has used unsophisticated (and not particularly hearty) microbes such as Clostridium acetobutylicum. The problem with this type of microbe is that it is poisoned by the very butanol it produces once the alcohol concentration rises above approximately 2 percent. This processing problem caused by the inherent weakness of generic-grade microbes, plus inexpensive and abundant (at the time) petroleum gave way to the simpler and cheaper distillation-from-petroleum method of refining butanol. My, how times change. In recent years, with petroleum prices heading steadily upwards, and worldwide supplies getting tighter and tighter, scientists have revisited the fermentation of sugars for the manufacturing of biobutanol. Great strides have been made by researchers in creating â€Å"designer microbes† that can tolerate higher concentrations of butanol without being killed off. The ability to withstand harsh high concentration alcohol environments, plus the superior metabolism of these genetically enhanced bacteria has fortified them with the endurance necessary to degrade the tough cellulosic fibers of biomass feedstocks such as pulpy woods and switchgrass. The door has been kicked open and the reality of cost competitive, if not cheaper, renewable alcohol motor fuel is upon us. Advantages So, all of this fancy chemistry and intense research notwithstanding, biobutanol has many advantages over here-to-fore easier-to-produce ethanol. Biobutanol has a higher energy content than ethanol, so there is a much lower loss of fuel economy. With an energy content of about 105,000 BTUs/gallon (versus ethanol’s approximate 84,000 BTUs/gallon), biobutanol is much closer to the energy content of gasoline (114,000 BTUs/gallon).Biobutanol can be easily blended with conventional gasoline at higher concentrations than ethanol for use in unmodified engines. Experiments have shown that biobutanol can run in an unmodified conventional engine at 100 percent, but to date, no manufacturers will warrant use of blends higher than 15 percent.Because it is less susceptible to separation in the presence of water (than ethanol), it can be distributed via conventional infrastructure (pipelines, blending facilities and storage tanks). There’s no need for a separate distribution network.It is less corrosive than ethanol. Not only is biobutanol a higher-grade more energy dense fuel, but it is also less explosive than ethanol.EPA te st results show that biobutanol reduces emissions, namely hydrocarbons, carbon monoxide (CO) and oxides of nitrogen (NOx). Exact values depend upon the engine state of tune. But that’s not all. Biobutanol as a motor fuel- with its long chain structure and preponderance of hydrogen atoms- could be used as a stepping-stone in bringing hydrogen fuel cell vehicles to the mainstream. One of the biggest challenges facing hydrogen fuel cell vehicle development is the storage of onboard hydrogen for sustainable range and the lack of hydrogen infrastructure for fueling. The high hydrogen content of butanol would make it an ideal fuel for onboard reforming. Instead of burning the butanol, a reformer would extract the hydrogen to power the fuel cell. Disadvantages It is not common for one fuel type to have so many obvious advantages without at least one glowing disadvantage; however, with biobutanol versus ethanol argument, that doesn’t appear to be the case. Currently, the only real disadvantage is there are many more ethanol refining facilities than biobutanol refineries. And while ethanol refining facilities far outnumber those for biobutanol, the possibility of retrofitting ethanol plants to biobutanol is feasible. And as refinements continue with genetically modified microorganisms, the feasibility of converting plants becomes greater and greater. It’s clear that biobutanol is the superior choice over ethanol as a gasoline additive and perhaps eventual gasoline replacement. For the past 30 years or so ethanol has had most of the technological and political support and has seeded the market for renewable alcohol motor fuel. Biobutanol is now poised to pick up the mantle.
