The International Expansion of Design Practices Essay Example for Free

The International Expansion of Design Practices Essay Designing world-class structures is now made easier with software that any architect in the globe may use in the privacy of his home.   3D modeling, rendering and animation software is but an example of such specialized software, making it easier for architects around the world to compete in designing architectural marvels (Advanced Micro Systems, Inc.).   As a matter of fact, architects are already competing to create the world’s best designs.   By their interaction alone, the world of design must be raising its levels of competence to build finer, safer and more beautiful buildings (Coduto).   Ã‚  Ã‚  Ã‚   The Kalo Opera Festiva and Danske Arkitekters Landsforbund (the federation of Danish Architects), together with investors were expected to initiate an international architectural competition around the end of the year 2003 (â€Å"International Architectural Competition†).   In the year 2004, the Friends of the Canadian Museum for Human Rights Inc. announced that there were three architectural firms selected by the Architectural Review Committee in one of the stages of the International Architectural Design Competition (ArcSpace.com).   Then there are international competitions that encompass only a specified region.   In Asia, ten architectural companies from Thailand were chosen for an international reward in the year 2005 (Asia Africa Intelligence Wire).   Ã‚  Ã‚  Ã‚   Unsurprisingly, such international competitions urge today’s architect to not only improve his designs by learning from global talents that he competes with, but also to work on becoming the very best in the global field of design practices.   Twenty four design firms from all over the globe submitted proposals to compete for the position of Master Designer of the Orange County Great Park (PR Newswire).   Undoubtedly, all of the proposals submitted were excellent, and world-class!   However, only one architect was to become a true model for the rest of the architectural community to follow.   Ã‚  Ã‚  Ã‚   As mentioned before, architects are getting together at the regional level as well.   This practice is also very healthy for their profession.   The city of the angels regularly lists its top architectural firms, each inspiring the others (Kissock).   The American Institute of Architects claims that â€Å"good design makes a difference.†Ã‚   This association of architects describes itself thus: â€Å"For almost 150 years, members of The American Institute of Architects have worked with each other and their communities to create more valuable, healthy, secure, and sustainable buildings and cityscapes.†   Ã‚  Ã‚  Ã‚   The architectural community in Australia is said to have received many international awards for its designs (Johnston).   What is more, the entire international community of architects has its own list of top international design firms (KEO International Consultants)!   The competition is stiff, and absolutely healthy.   Under the watchful guiding eye of the top-notch international community of architects, it is difficult for an architectural firm to make an inferior design and thereby endanger the safety of the people who would be occupying the building thus designed.   The world of architectural design is expecting improved output at all levels and at all times.   This international expansion of design practices makes for a safer and more beautiful world.   Ã‚  Ã‚  Ã‚   Given the above facts, we hypothesize that the international expansion of design practices is good for the architectural profession.   With the advent of the Internet and the glories of globalization and technology, it is expected that architects around the world must have seen massive improvements in their designs, seeing that they now have access to superior designs from around the world that serve as models in their work.   In this case, as in most others, global heads are better than one!

A Dolls House as a Problem Play

A Dolls House as a Problem Play A Dolls House is one of the major realistic problem plays of Henrik Ibsen. In A Dolls House, Nora Helmer is the main character. She is the wife of Torvald Helmer, who is a bank manager. The story happens when Christmas is coming. To keep the job in Torvalds bank, Krostad, who is the man that Nora borrowed money from to pay the trip to Italy to cure her husband, threatens her that he will tell Torvald she forged her fathers signature to borrow money if she doesnt help him to talk with Torvald. She tries to do what Krostad wants because she is fearful that she will lose the family when Torvald knows about that. However, what she is afraid of happen. She spends a whole night to think about what happened, and she realized that Torvald and she dont understand each other. Finally, she decides to leave him and her children to discover her own life where she can find her own self. By separating the various themes of faux marriage and broken family, Henrik Ibsen focuses on the place of women with Nora as his central character. Nora chooses divorce at the end to free not only Torvald but also herself. Just holding a marriage without love, communication, trust, and toleration, the marriage between them cannot last forever. The reasons that lead to divorce in the play are relevant in the world today. Love is the first base to build a strong marriage. Without love, marriage will be destroyed easily. In A Dolls House play, the marriage of Torvald and Nora is seemed very happy, but truthfully, Torvald didnt really love Nora. With him, she is woman who is under his control. After her forging her fathers signature is disclosed, she realizes that her marriage is built without their real love. Torvald pretends to love Nora, and she pretends to love him. She feels that she is living a lie while she lives with him as a doll. She did and thought the same as what he said. Nora claims, à ¢Ã¢â€š ¬Ã‚ ¦You arranged everything to your tastes, and I acquired the same tastes. Or I pretended toà ¢Ã¢â€š ¬Ã‚ ¦ I dont really knowà ¢Ã¢â€š ¬Ã‚ ¦ I think it was a bit of both, sometimes one thing and sometimes the other. When I look back, it seems to me I have been living here like a beggar, from hand to mouthà ¢Ã¢â€š ¬Ã‚ ¦(Ibsen 858). When Torvald asked whether she had been happy living with him or n ot, she answers no although she hopes that she was. Therefore, building a marriage without love definitely hurts the relationship between husband and wife as it hurt the relationship between Torvald and Nora. A balance of love is needed in any marriage. Another quality that leads to failed marriage in the play and the world today is the lack of communication. Two soul-mates need to communicate in a relationship. Because Nora understands Torvalds character and doesnt want to let him worry, she didnt talk to him about borrowing money from Krogstad to cure his illness. Moreover, when they talk to each other, they always say about money and work. In the Act I, Nora is seen as a spendthrift her husbands eyes. She always says money when Torvald asks her what she wants. Because of that fact, Torvald seem to be a person who really loves his wife when he agrees with all her requests, but he didnt know what she really wants. The lack of communication makes them cannot understand each other. In the play, Nora realizes that they didnt talk enough through eight years when she says, We have now been married eight years. Hasnt it struck you this is the first time you and I, man and wife, have had a serious talk together? (Ibsen 858). The answer wa s no. That is why Nora didnt tell her husband about her secret. Just because of the poor communication, a marriage can never hope to live onward. Although love and communication are important in marriage, trust is also necessary to build a marriage stronger. Torvald had almost no trust in Nora. When Nora needed some money to buy some things for Christmas, he jeered at her. He state, à ¢Ã¢â€š ¬Ã‚ ¦if only you really did buy something for yourself with it. But it just get mixed up with the housekeeping and frittered away on all sorts of useless thing, and then I have to dig into my pocket all over again (Ibsen 815). With spendthrift character, Nora lacks trust in her husband, and it is not good for their marriage. It makes them have no trust or even suspect each other. Without trust, marriage becomes impossible. Last but not least, toleration is also necessary in marriage to help them closer. Although they have a good relationship, if they dont have toleration, they will be separated. In the play, both Torval and Nora dont have toleration. This is one of the reasons that lead to their divorce. When Torvald know about what Nora have done, he very angry and doesnt want to forgive her for her fault. He even requests that she has to stay away form him. When he reads the second letter from Krosgtad, he is calmed down and forgives for her fault, but it was too late because she realizes that he didnt love her. She is the same as her husband. She cannot forgive for a person who cares nothing more than him. She finally decides to leave her family to discover a new life where she can find her own self. She says, If I never reach any understanding of myself and the thing around me, I must learn to stand alone. Thats why I cant stay here with you any longer (Ibsen 859). With the strong tone, her determi ned attitude about leaving is shown up although Torvald begs her to stay with him. In conclusion, A Dolls House is a great play of Henrik Ibsen. A Dolls House leaves us a message that holding a marriage without four qualities above is impossible. The marriage of Torvald and Nora Helmer had many problems because they got married without real love, hold their marriage without trust, have the poor communication to understand each other, and have no toleration to forgive for their faults. A Dolls House teaches us a lesson that getting married with our loves is easy, but keeping our marriage can last forever is not easy as we thought. Work Cited Ibsen, Henrik. A Dolls House.

Male Carica Crude Solvent Extracts

Male Carica Crude Solvent Extracts Male pawpaw tree have flowers that grow on short stalks (Chin et al., 2001). Carica papaya is a native of the tropics of America, perhaps from Southern Mixico and neighouring central American (Morton, 1987). According to Eno et al. (2000), pawpaw is the fruits, of the plant. Carica papaya belong to the genus carica. Preliminary qualitative and quantitative phytochemical analysis of ethanol and aqueous extracts of C. papaya showed the presence of many phytocompounds. These extracts were found to inhibit these eight test micro-organisms: Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella typhi, Escherichia coli, Aspergillus niger, Penicillium notatum, Fusarium solani and Candida albican.(Okoye, 2011). Proximate analysis of leaves of C. papaya also showed appreciable quantity of ash content, crude protein, crude fat, crude fibre, carbohydrate and high calorific value (Okoye et al., 2011). In this present work, the author intends to study the preliminary pharmaceutical constituent s of crude solvent extracts of flower and stalk of male Carica papaya since little or no work had been done in this area. The aim and objective of this work is to determined the phytocompounds present in flower and stalk of male Carica papaya; to extract the crude solvent extracts of the flower and stalk of male C. papaya and to find out whether the solvent extracts can inhibit the growth of ten pathogenic fungi. Carica papaya is composed of many biological active compounds, many of which are found concentrated in the latex, which is present in parts of the plant (Madrigal et al., 1980). Within Carica papaya plants, the concentration of bio-actives will vary with position of plant, age of plant and cutivar. Also, concentration of bioactive differs between male, hermaphrodite and female plants. Female plants exude more latex than hermaphrodite and male plants. Carica papaya latex is rich in cystein proteinases which are proteolytic enzymes (caricain, chymopapain, papain and glucylendopeptidase) these constitute 80% of latex enxymes. Other enzymes present are glycosyl hydrolases (à ¯Ã‚ Ã‚ ¢-1, 3-glucanases, chitiriases and lyzozynus) protease inhibitors (cystertin and ghtaminylcyclotrunsferces and lipases (Moussaoul et al., 2001). It was reported that intake of two table spoons of pulverized papaya seeds mixed with hot water twice per day is used in the traditional management of diabetes and obesity (Adeneye and Olagunju, 2009). Carica papaya (pawpaw) contains the enzyme papain, a protease used for tendering meat and other proteins (Morton, 1987). The fruits are popu larly used and processed into juice and wine, and also cooked as vegetable (Gragson, 2001). The seeds are medically important in the treatment of sickle cell disease and poisoning related disorder. The lead tea or extract had a reputation as a tumor destroyer agent. The flesh green tea is antiseptic while the brown dried leaves are best served as tonic and blood purifier (Ezugwu, 2008). Due to its antioxidant and fibre content, it is used in treatment of ailments such as chronic indigestion, overweighing, obesity, high blood pressure (Everetta, 2003). Sample Collection and Preparation Flower stalk of male Carica papaya was collected from Adazi-enu in Anaochia Local Government Area of Anambra State, Nigeria. It was dried under air and mild sun-shine, for about three weeks and ground into powders. The ground sample was then kept in a clean polyethylene bottle until needed for analysis. Phytochemical and the extraction of the active components are determined by the methods outlined by Harbon (Harbon, 1973). The antifungal activity of flower and stalk of male C. papaya was determined by agar well diffusion method (Okeke et al., 2001). The zone of inhibition was recorded to the nearest size in mm (Norrel, 1997). After extraction of the active components using three different solvents separately (Ethanol, Water and N-hexane), the solvent extracts were evaporated to dryness at about 67, 98 and 66 °C respectively in a water bath separately. 1, 2, 3, 4 and 5mg of dry ethanolic, n-hexane and water extracts were weighed into five different labeled test tubes differently. T hen 10ml of the corresponding solvents used for extraction was added to the dried extracts to make 0.1,0.2,0.3,0.4 and 0.5mg/ml concentrations of the extracts. The MIC of flower and stalk of male Carica papaya were found out by using 0.1, 0.2, 0.3, 0.4, and 0.5mg/ml of each extract which were added to test tubes containing 1ml of sterile medium. The tubes were then inoculated with a drop of microbial suspension and incubated for 48 hours at 25 °C. Then 0.1, 0.2, 0.3, 0.4, and 0.5mg/ml of amphotericin B (for A. flavus, F. verticilloides, A. parasiticus, F. oxysporum and Fluconazole (for all candida was used for positive control and water for negative control respectively. The MIC value was determined, macroscopically after incubation in comparison with the growth and sterility control. MFC; the plates (petri-dishes) were divided into six different sections and labeled with the different concentration on the base of the plates, these were used to plate out the contents of each tube with the respective sections of the plate. The plates were incubated for 18 24 hours at 37 °C after which the MFC were recorded. Three replicates were done fo r each extract concentration and control against the fungi.

The phytochemical constituents of the flower and stalk are as follows: alkaloids 0.53  ± 0.01%, floaonoid 0.08  ± 0.02% saponins 0.37  ± 0.02% tannins 2.06  ± 0.01%, terpenoid 0.02  ± 0.01%, steroids 0.08  ± 0.01, phenol nil, cardiac glycoside 1.87  ± 0.02%. The flower and stalk of male Carica papaya contain an appreciable quantity of alkaloids. It could be used to remedy some diseases, depending on the type of alkaloids it contains. The presence of alkaloids signified the possession of medicinal values within the flower and stalk. Pure isolated alkaloids are used as basic medicinal agents and fungicidal properties. The presence of steroids in the sample indicates that it could be used to decrease the presence of cholesterol in the bloodstream. Saponins have been used in the treatment of cardiovascular disorders, they facilitate and ea se the process of digestion and encourage the growth of beneficial bacteria within the intestine. Saponins also contribute to health and efficiency of the immune system by binding to germs and other pathogens as they enter the body. In this sense they function as natural anti-bodies. They are found to be antimicrobial and are particularly effective when used to treat yeast a infections. The presence of cardiac glycosides in the flower and stalk of male Carica papaya indicates that it could be used, in the treatment of congestive heart failure and cardiac arrhythmia. Table 3 portrayed the result of antifungal activities of three solvent extracts of the flower and stalk of male Carica papaya on ten micro-organisms (fungi) investigated in this work. They are: A. niger, M. gyspseum, C. albican, A. flavus, F. verticilloides, A. paraciticus, F. oxysporum, C. glabrata, C parasilosis and C. tropicalis. Five different concentrations of aqueous, ethanolic, and normal hexane extracts were used. At 0.1-0.5mg/ml concentration, aqueous extract showed some inhibitory effect on eight out of the ten test fungi. The fungi are; A niger, M. gypseum, C. albican, A flavus, C. parasilosis, A. parasiticus, C. glabrata and C. tropicalis. No action was recorded on the two remaining test fungi: F. verticilloides and F. oxysporum. At 0.1-0.2mg/ml concentration, ethanol extract shows some inhibitory effect on seven out of the ten test fungi. These are: A, niger, M. gypseum, C. albican, A. flavus, C. glabrata, C. parasilosis and C. tropicalis. At 0.1-0.2mg/ml, ethanolic extr act shows no action against three fungi. These are; F. verticilloides, A. parasiticus, and F. oxysporum. At 0.1-0.5mg/ml, n-hexane extract indicated some inhibitory effect on six out of the ten test fungi. These are: A, niger, C. albican, A. parasiticus, C. glabrata, C. parasilosis and C. tropicalis. It had no action on four fungi. These are: M. gypseum, A. flavus, F. verticilloides and F. oxysporum.. Table 3 also showed the commercial drugs used as positive and negative control. Positive control using two different antibiotics specifically showed remarkable inhibitory effects on the ten test fungi while the negative control showed no action against the ten test fungi. Table 4 showed the results of the minimum inhibitory concentration (MIC) of the aqueous, ethanolic and n-hexane extracts of flower and stalk of male Carica papaya on the ten test fungi. The least MIC of the aqueous extract 0.05  ± 0.01mg/ml was shown on five test fungi: These are A. niger, A. parasiticus, C. glabrata, C. parasilosis and C. tropicalis. MIC of the ethanolic extract 0.05  ± 0.0lmg/ml was shown on four test fungi. These are, C. albican, A. flavus, C. glabrata, and C. parasilosis. MIC of the n-hexane extract 0.05  ± 0.0lmg/ml was shown on five test fungi. These are: C. albican, A. parasiticus, C. glabrata, C. parasilosis and C. tropicalis. Table 5 showed the result of minimum fungicidal concentration (MFC) of the aqueous, ethanolic and n-hexane extract of flower and stalk of male Carica papaya on ten test fungi. For aqueous extract, the least MFC 0.2  ± 0.01mg/ml was shown on one test fungi,Candida albican. For ethanolic extract, the MFC 0.02  ± 0.0lmg/ml was shown on one test fungi Candida albican. For n-hexane extract the least MFC 0.02  ± 0.01mg/rnl was shown on one test fungi: Candida glabrata. Conclusion The analytical investigation showed that, the crude solvent extracts of flower and stalk of male Carica papaya have antigfungal effect on these microorganisms; Aspergillus niger, Microsporum gypseum Candida albican, Aspergillus flavus, Aspergillus parasiticus, Candida glabrata, Candida parasilosis and Candida tropicalis. This implies that crude solvent extracts of flower and stalk of male Carica papaya can be used to cure the diseases caused by the above mentioned microorganisms. Bioactive ingredients responsible for the antimicrobial properties of the flower and stalk of male C. papaya should be elucidated.         Ã‚   Male C. papaya Plant Flower and Stalk of male Carica papaya References 1.Okoye, E.I., Orakwue, F.C. and Ebeledike, A.O.

John Walker :: essays research papers

John Walker Lindh, the American accused of fighting alongside the Taleban, has been formally indicted on 10 charges of conspiring to kill fellow Americans. The US is a country of laws, not of men... Walker Lindh only recognised the law of brute force US Attorney General John Ashcroft The indictment, which was handed down by a grand jury in eastern Virginia, formalised the six charges filed against him last month and added four more. The 10-count charge sheet represents the next step in the case against the 20-year-old Californian Muslim. He faces multiple life sentences if convicted. Asked at a press conference whether the government would ask the grand jury to charge Mr Walker with treason, US Attorney Paul J McNulty said: "As far as other charges, we have the opportunity or right to have a superseding indictment if the evidence justifies that." 'Trained terrorist' Announcing the indictment at the US Justice Department, Attorney General John Ashcroft said it described Mr Walker as "an al-Qaeda-trained terrorist who conspired with the Taleban to kill his fellow citizens." He said the indictment was based in part on voluntary statements made Mr Walker. The new charges are: Conspiracy to contribute services to al-Qaeda Contributing services to the network Conspiracy to supply services to the Taleban Using and carrying firearms and destructive devices during crimes of violence Mr Walker had already been charged with: Conspiracy to murder US citizens or US nationals Two counts of conspiracy to provide material support and resources to designated foreign terrorist organisations Two counts of providing material support and resources to terrorist organisations Supplying services to the Taleban Mr Ashcroft said the indictment presented a timeline of Mr Walker's involvement with terrorism. The charge sheet said that in early summer 2001, Mr Walker was in an al-Qaeda training camp in Afghanistan. Later, as the network made their alleged preparation for the attacks of 11 September, Mr Walker was "forging ever deeper bonds" with al-Qaeda and met America's foremost suspect, Osama Bin Laden, Mr Ashcroft said. Mr Ashcroft said that on the day of 11 September, Mr Walker was fighting alongside the Taleban in Afghanistan, and in the weeks after the attack he remained with his fighting camp, despite knowing about the suicide attacks and being aware that additional attacks were planned. Walker's father is standing by his son

Condoms Essay -- Sex Protection Condoms Descriptive Process Essays

Condoms The word condom is probably derived from Latin "condus" meaning receptacle. Another explanation is that the gut condom was invented by the English army doctor Colonel Quondam in around 1645 and that the word is a corruption of his name. We do not know who invented condoms, but we do know that they were in use. There is evidence of this in the writings of Marquis de Sade, Casanova and James Boswell. The latter, a Scottish lawyer and writer, protected himself against sexually transmitted diseases by using a linen condom. During a visit to an Amsterdam brothel in 1764, he drank with a prostitute, but the encounter went no further as he'd left his "armour" behind. When visiting a brothel in Marseilles, Casanova tried so-called "English raincoats", and spoke of reaching great heights. The oldest illustration of a condom was found in Egypt and dates back more than 3,000 years. It is difficult to judge from the drawing what the ancient Egyptian wearing the condom had in mind. He may have worn it for sexual or ritual reasons-or both. Some claim that, in later times, the Romans made condoms from the muscle tissue of warriors they defeated in battle. The oldest condoms were discovered in the foundations of Dudley Castle near Birmingham, England. They were made of fish and animal intestine and dated back to 1640. They were probably used to prevent transmission of sexually transmitted infections during the war between the forces of Oliver Cromwell and soldiers loyal to King Charles I. Ancient Times Throughout the age's people have tried to find ways of preventing conception and venereal diseases. Obvious methods, such as withdrawal, the rhythm method, douches, and sponges were used, as were various predecessors of today's condom. In ancient Egypt, a linen sheath was used as protection against troublesome insects and tropical diseases. The Chinese tried to prevent infection by wrapping oiled silk paper around the penis, and the Japanese had leather and tortoiseshell sheaths. The Romans used tampons that had been dipped in herbs and condoms made of goats' bladders. Middle Ages The history of condoms in Europe begins in the sixteenth century, when the venereal disease syphilis reached epidemic proportions. In 1564, the Italian doctor Gabriel Falloppio wrote in the book 'Morbo Gallico', that a linen bag drenched in a solution of salt or herbs formed a ... ...ave a variety of condoms, which will please even the most discriminating tastes. You may even like the taste of flavored latex more than the real thing! Some alternatives to the dental dam Dental dams offer a unique kind of problem. Many people do not like to use dental dams because they like to feel the tongue to clitoris or tongue to anus stimulation. Along with dental dams, you can employ some other stimulation to complete the experience. Wear a latex glove covered in lubricant to further tease your partner's anus or vagina. If dental dams are becoming a problem because you are tired of holding something on your partner, you can use plastic wrap and wrap it around the vagina and/or anus. While cellophane is not as good protection as latex (and should never be used instead of condoms), using it will keep the hands free to use elsewhere. Use lubricant inside and outside the condom. (Many condoms are pre-lubricated.) Lubrication helps prevent rips and tears, and it increases sensitivity. Use only water-based lubricants, such as K-YÂ ® jelly or LUVE, with latex condoms. Oil-based lubricants like petroleum jelly, cold cream, butter, or mineral and vegetable oils damage latex.

Professional, mental, moral and aesthetic development Essay

There has been increased demand for education from different kinds of people in the world, due to the introduction of information technology in their countries. Therefore people have increasingly sought for ways and means to acquire knowledge to enable understand the realities of life as they occur. Education is the process through which teaching and learning of knowledge, enables an individual to develop reasoning, judgment and skills required in adult life and professional occupations. Education focuses on the cultivation of skills trades or professional, mental, moral and aesthetic development . There are two types of education; formal and informal education. Formal education refers to the education whereby there is system of instruction, teaching and training by the professional teachers. Here, there is a curriculum to be followed and use of different teaching methods. Traditionally, educators borrowed information for education from many different disciplines for example psychology, philosophy, information technology linguistics, biology and sociology. A person can be trained by a specialist so as to get specific skills for example a pilot. Systems of formal education are established to provide education and training for children. A curriculum states what a student should know and be able to do as a result of education. Informal education involves acquisition of knowledge and skills learned and refined during one course of life. The right to education is a basic human right. Education can be attained informally through institutions such as libraries and museums (Shards, K. , and Smith, S. J. 2000). The central purpose of education The central purpose of education is to teach a student on values that will enable him to develop his mind and be in a position to deal with realities of life. Training that is given to the students enables them to think, understand, integrate and prove all information that they have been taught. Students are taught essentials of knowledge that is achieved in the past experiences and also trained to acquire knowledge by him. An example of purpose of education is the teachers’ transmission of knowledge to the students. One of the things that education does is to equip people with power to think effectively and objectively. Education should assist a person to be critical in terms of the truths, prejudices and propaganda. Education should enable the people to distinguish between true or false information, relevant from irrelevant information, real and unreal information. Part of education teaches the human beings to be critical thinker’s . For education to be whole; it should be morally right to the recipients of the information. Morals help a person to avoid wandering from one place to another and gives the persons power of concentration and reasoning. For one to concentrate well, he or she should have worthy objectives in order to meet that they would like to achieve in the future. The kinds of people schools should seek to develop The characteristics of people who can be a successful learners are they should be knowledgable, self determined, strategic, and empahthetic. They also have creative and critical faculties, motivation to learn and confidence about themselves as learners, tools and strategies for acquiring, evaluating and applying knowledge. They also have insights about motives, feeling and behavior of others and can effectively communicate with others. Schools should seek to develop individuals who are well rounded in terms of knowledge and work experience. Discipline is a trait which is experienced in our everyday life. Instances like getting to work on time, finding appropriate clothes, scheduling appointments, time management are skills learnt through learning. The ability to list work experience in curriculum vitae demonstrates qualities such as enthusiasm, initiative, work ethic and a genuine desire to work. Schools should also seek to develop people who are confident. This occurs when an individual feels that a task is within their reach. Work experience is important as it gives one a chance to watch people do a job, ask questions and frequently get the chance to try out the work. Being knowledgeable is equally important. This is because employers are interested in what an individual can do. If one can display an understanding of an industry and support by outlining key tasks based on experience, he or she has chances of gaining employment. When looking for placement, schools should encourage students to keep as many contacts as possible. The reason is that meeting people who can help in job seeking process can lead to one acquiring a position in the job market (Smardz, K. , and Smith, S. J. 2000). The ways in which the school can work toward greater equity Schools and communities have people from different races, gender, sexual orientation, class, language and religion which allow them to have equitable opportunities . For a positive change to be noted, change in individual, schools, communities would work together and aim to maintain diversity and equity. In schools, it means going beyond cultural differences and celebrating diversity. This in turn breeds open conversations about equity related issues and what those issues mean in the classroom or administration and in schooling at large. These issues include bullying, school culture, classroom climate, achievement gaps and others. It’s only possible to discuss these issues only if the real conversations about socio- economic status, gender, race because they have an impact on students, teachers, administrators, parents and community members. The main challenge is to find out whether schools offer an opportunity for an individual to achieve the best and have access to an equitable valid supportive learning environment regardless of race, gender, (dis)ability, and other dimensions of his or her identity. One goal of education is to measure work based on how much closer we help a school eliminate inequity. This can be achieved on the basis of the specific contextual needs of each school or organization. A workshop may be set up to place emphasis on achievement gaps, teacher expectations and effective methods of teaching for diverse students. The workshop may also be on racial tensions or gender equity in the classroom. Teachers on the other hand need strategies for implementation practical ideas, curricular tools, classroom activities and teaching methods that support diversity and equity. As teachers try to solve students’ issues in education, they need to balance the practical with the philosophical and also providing immediate strategies for long term needs and institution changes ( Smardz, K. , and Smith, S. J. 2000). The values of an educator and how those values are formed and informed There are some values that educators should be committed to develop that enable students accomplish goals and aims. An educator who is competent has characteristics such as well developed knowledge and skills in content areas and methods of teaching. This educator understands how children learn at various developmental stages and also provides learning opportunities that support their intellectual, social and emotional development. He also uses multiple forms of assessment to guide instruction and other interactions with students. The educator who is caring values respect and trust reflecting a humanistic orientation to students and other members of the school community . He or she is child centered, nurturing and a facilitator of personal growth and self esteem. This educator motivates students to excel and be self confident. He provides a caring environment whereby students take risks and explore openly. Service is a value that the educators should thrive to attain . This is because it’s viewed as an opportunity to make positive difference in the lives of others. He seeks for ways to provide service to students and the education profession, school community and the community at large. The educator is mostly committed to take action on behalf of others even if such action requires measure of self sacrifice. These concerns are extended to his or her sphere of knowledge and influence. In addition, the educator has a disposition towards civic and social responsibility in the local community, nation and even the world (Tozer, S. E (2000). Leaderships is also a core value in this case the educator purses the goals of powerful learning and positive student achievement using the collaboration and supportive interaction within the classroom, school and community. The collaboration provides the support for continuous and consistent delivery of instruction to all students. This leader is well informed about the nation and educational reforms and uses personal skills to restructure environments to improve practice. He or she has a vision of setting that encourages efficacy and excellence, communicates his vision to constituents and leads them in the construction and implementation of shared vision of good schools. The education leader requires this to promote effective practices and organizational structures in places of work. He faces up these challenges because they in turn promote social justice and equity in the classroom, school and community. Issues like discrimination are given special attention especially in support of students with special needs ( Smardz, K. , and Smith, S. J. 2000). The role of the teacher in schools and wider society One of the roles of the teachers is to ensure that they promote integration between students from different backgrounds. This means that the teachers do not teach the same as the time passes by. Teachers play a role in teaching process to even becoming managers in the society so that to ensure the education system and society as a whole move from a long side by side. This movement towards monitoring and evaluation of the quality and performance of the national education system has unduobtfully began to have an impact in the way in which education is regarded both by the society at large and the people who are directly involved. A teacher is seen as a role model for the students . This is because he or she is respected by the society and therefore viewed as knowledgeable about different subjects of schools. Though teachers are seen as role models they still make mistakes, it’s therefore the role of the student to compare and pick only what is beneficial to them. The teacher is a dynamic force for the school, for a school without a teacher it is like a skeleton without flesh and blood (Tozer, S. E 2000). It is therefore important for people to attend school at early age so that they can acquire relevant information that can help them to be useful members of the society since they can be able to appreciate the realities of life as they occur.

Normalcy

Normalcy in other words means to me to have everything up and running as required. To be stable with no corruption. Normalcy is something both Warren Gamaliel Harding along with Calvin Coolidge wish to restore in the U. S. Sadly Harding does nothing suitable to return normalcy but only to continue adding to the corruption already occurring. Coolidge on the other hand takes control after the death of Harding in 1923 and accomplished much more than Harding might have ever did. During the presidential time of Coolidge the Kellogg-Briand act was put to be followed. Lets discover what made these two men so different from one another! Warren Gamaliel Harding happened to be the 29th president of the United States. He served from 1921 till his death in 1923 due to a heart attack. Truth be told he was considered to be the worst president of all time. In the election of 1920 U. S presidential candidate Warren promised to return the country back to the way it was before WW1 occurred. For example as a quote stated by Harding himself â€Å"America’s need is not heroics but healing†¦we need to return to normalcy. Harding was known for the Teapot Dome scandal which took place in Wyoming. As oil reserves that were in the custody of Harding were being improperly used by being leased to private oil companies by the secret interior Albert Fall, Albert himself accepted cash gifts and no-interest loans from the companies. As we can see in Harding’s attempt to re-create peace he failed epically. This caused Harding’s administration to be remembered as the most corrupt in the white house. John Calvin Coolidge, jr was the vice president at the time when Harding was president. After the death of Harding, Coolidge took his place into becoming president. Coolidge slowly departed himself from the Harding administration and also removed all officials suspected of corruption. Coolidge decided to continue Harding’s policies while trying to eliminate scandals. Coolidge did promise to return normalcy to the United States, something Harding was unsuccessful at doing. In 1928, the Kellogg-Briand Pact was created between fifteen countries stating war will now be illegal. In my opion I believe Harding had no idea of what he was doing. He allegededly hired his old poker friends known as the Ohio Gang to work along side him. Some members from the Ohio gang used their government positions to take advantage of the money for personal use. I believe Coolidge kept his word at all times returning the U. S back to normalcy. Once Coolidge made all the necessary changes required the U. S was back to the way it was before WW1 occurred. In my belief Coolidge is a man of his word and is trustworthy.
