A Problem By Society Children And Young People Essay

A Problem By Society Children And Young People Essay Limited scholarships and seats for admission in schools and colleges imply a rise in the competition level. Overcrowded schools lead to indiscipline and a lack of control. Teachers are unable to cater for the individual needs of children. This issue has been further discussed under the heading entitled School. According to Pearson (1983), intervention of social welfare services have a big role in crime prevention. They detect and help abused and ill-treated children. However, in disorganized areas social welfare officers have many families to look after. The cry for help of many children and parents in these areas remain unheard. It is only when the issue has become serious that the authorities intervene. It is often too late. Some end up being traumatized for life or victims of un-repairable damage do. Since there is much insecurity in these localities, businesses to move away and investors refrain from putting their money in developments occurring. This increases problems of unemployment. It is hard in itself to live in suburbs and when employers see that a job applicant comes from a badly reputed region, the chances of the later getting the job diminishes considerably. Moreover, as mentioned earlier, most youngsters coming from these areas already have police records, poor academic knowledge and without legitimate means of obtaining success, they feel social and psychological strain (Merton;1920s). Furthermore, as French sociologist Pierre Bourdieu said: Parents occupation and level of education have significant effects on the life chances of their children. From an economic perspective, these youths breach the law for their financial well being. This rational choice seems acceptable from the youngsters point of view when we consider the lack of proper educational system, equal and legal job opportunities. It is his survival strategy just like it had been for his family members and neighbors. (See School failure) Aggressive and violent youth Another problem which arises when there is a high rate of teenage population is a demographic area is that of violent crimes. Their poor problem-solving skills, overly sensitive or emotional personality and explosive temperament combined with their biological and physical predisposition of being violent and aggressive because of their age; make them apt of committing aggressive assaults and crimes. Small discussions and debates can end up into bloody attacks. Indeed, disorganized neighborhoods suffer from social incivility. It is common to hear swearing words and see people fighting on the streets, to see graffiti, broken window panes, young children roaming till late on the road, and sex workers almost everywhere. Family disruption Community fear, lack of social facilities, unemployment and bad quality of education for the children create a lot of fuss and stress on parents. Also families, in these areas of high violence rate, have disrupted social relationships. It is common to find families which have financial problems, depressive and stressed parents who adopt drinking and other bad habits and who have problems in growing up their children. This has been further discussed in Family. Social mobility Residents of these areas try to get used such disorder and atrocious crimes that occur on the streets around them. They lose trust in authorities and feel abandoned. They rarely report offences they witness or are victims of. On the contrary, fearing for their life and security they join gangs and peer groups which will protect them in case of difficulty. This leads to the development of criminal areas and generations of criminals. Many families want leave these deteriorated communities and look for a better place to grow their children into better adults. This social mobility leads to limited collective efficacy. There is weakened social control. Neighbors might not know and trust each other. This is constant fear and insecurity and no cohesiveness among inhabitants. Government policies and initiatives taken up by NGOs do not work since residents do not stay for long to implement them. Indiscipline in schools, the lack of individual care for needy students, availability of drugs and arms and a troublesome family life can result tragic incidents. On December 14, 2012 Adam Lanza shot 20 children and 6 staff members in a school in Connecticut. Growing up in a disorganized and less privileged society is tough enough without having to be worried about being killed while going to class. Unfortunately, events like these occur because of a multitude of factors which are not always controllable. Duncan and Murnanes book, Neighborhood and Family Impacts on Schools, examines à ¢Ã¢â€š ¬Ã‚ ¦how factors as family functioning, neighborhood conditions, school quality, and local labor markets impact schools ability to improve academic and educational attainment of disadvantaged students. We have seen how the education system favors academic learning and neglects personality development. Where a class is supposed to be a team of young learners, with each and every member being valuable, it has now become competitive environment in itself where making others lose seem to be synonym of victory. Some students find this sort of system challenging and do their best to be toppers in exams but on the other hand students who have, since their very young age, been exposed to severe and prolonged stress, are likely to have developed learning disabilities and emotional and behavioral problems which make is difficult for them to successfully go through the educational system. These students have to undergo a lot of pressure from members of their family, school and society. They may have attention deficit disorder, a lot of anxiety and can be depressive. However, instead of being spotted as care-needing students, teachers and also other students often labeled as stupid and lazy an d antisocial. Teachers do not actively listen to their problems. They simply lecture and maintain peace and order in classrooms. Teaching techniques are not adapted to the needs of children. There is no individualized care and support. Teachers who do not encourage students to succeed and condemn them because of their learning disabilities fail in their traditional role as gurus, guides and role models and add on to the distrust that children and youths have in adults. Subcultures Children tend to do what we do rather than what we say to do. To understand how a violent community affects teenagers and how it is related to youth crime we to take the social learning theory developed by Bandura, the differential learning theory developed by Matza, Sutherland, Cressy and others, and theories on subcultures. According to Gottfredson and Hirschi, family environment is the most important institution which has to foster self-control, good values and manners in a child. However as demonstrated by Bandura in the Bobo Doll experiment, there are different ways through which a child learns how to be aggressive but the main one is through observation and interaction with others. Parents living in a violent society cannot fully restrain and protect their children from all negative influences. Children can do both good and bad and discipline should be appropriately used for the former to prevail (Anderson; 1980). Parents cannot be held sole responsible for the social and moral education of their children. Other institutions have a crucial role to play. As seen earlier, the failure of one institution can lead to the failure of all the other institutions. Children who are abused and neglected by parents, experience school failure, rejection from society and have a low self-esteem are more likely to join gangs. We have seen under School failure and Indiscipline in schools how gangs form and function in schools. In a violent community, there are considerable numbers of gangs which operate. Sutherland and Cressy suggest that criminal behavior is learnt through criminal association. Criminal motives, techniques, attitudes and rationalizations are developed through interaction with others. Moreover, as Cohen suggests crime is collective in nature. Moreover, in most subcultures the violation of institutionalized and traditional behaviors is seen as normal as they have their own street rules and regulations. It is true that protective factors like social bonding and self-control mitigate the risk of offending but studies have proved that it is highly probable for children who grow up in violent environments to learn deviant behavior at home or at school or on the streets. In the longitudinal study of 400 London school boys, West and Farrington (1970) suggested that delinquency arises from a complex interaction between individual home atmosphere, the personal qualities of the boy and the circumstances in which the family lives. Hutchings We have also observed that inner controls can be a strong protective factor but it has to be fostered by not only parents but also teachers and society, who have to act like role models. Social controls, like attachment, commitment, involvement, and belief (Hirschi; 1970) are also protective factors which stop youth from acting delinquently. To conclude we can say that young children in violent communities are most likely to grow up as aggressive adults. The period of adolescence is characterized by physical changes, cognitive development, mood swings and social reorganization having as aim to grow into maturity and help fulfilling social and cultural expectation of becoming a responsible adult. Love, support, care and right education are more than essential for adolescents. A cozy environment can make all the difference. Unfortunately, for children who are in stressful environment, their life experiences will affect their personality, perspective and the type of adult they end up being. If parents, schools, peer networks, neighbors and other social welfare services are work in strong coordination and collaboration the duty of rearing children into responsible adults, not deviant ones, is like to be fulfilled. Since long, the responsibility of growing up a child into a responsible citizen has been bowled from the shoulders of parents and families to that of the government. Their transition from puberty to an age of maturity should be eased with love, support and care. Nowadays, the concept of childhood is being slowly wiped out. The transition period between childhood and adolescence and adolescence to adulthood seems to be shortening as years go by. Children and adolescents are partaking in adult activities at very early ages. Fashion brands, celebrity magazines, tv serials, advertisings and other bla bla are marketedly directly to them. Where media can be used to sensitize children, it is being used to provoke certain behaviors. Tv serials like Gossip Girls and Teen Mom, among among many others, promote dangerous sexual behaviors and pregnancies. Cognitive development- less reasoning ability Despair of parents/ cry for help should be heard by authorities + social welfare services appropriate actions should be taken each family has its own concerns and problems- tailor-made programs

Hero’s Heart Essay

â€Å"Not the glittering weapon fights the fight, but rather the hero’s heart. † (Proverbs Quotes) I agree with Proverbs, that the hero’s heart fights the fight because I believe that a hero can be a hero without having to use a weapon. I believe that a hero is someone that is mentally strong and has the ability to lead, that it is showing dedication to a quest, and that is not giving up even when the world around you seems like it has given up on you. Heroism is being capable of being mentally strong and has the ability to be a leader. In the poem A Man by Nina Cassian a man has lost an arm in while fighting for his country. The man knows that he â€Å"shall only be able to do things by halves. † (Line 3) Even though â€Å"the man† has lost an arm he realized that he had to â€Å"set himself to do everything with twice as much enthusiasm. † The man recognizes his limitations but still has the will in his mind to push forward and never stop living life just because of one little set back. Also, a daughter writes about her mother, Ana, who is struggling through cancer. Ana’s daughter says that even though she is going through cancer again â€Å"she gets up with a smile and still has the strength to be a mother to me. † This shows that Ana is mentally strong because she is able to care for her loved ones as for someone else they would most likely give up and not want to deal with the pain any longer, especially if they have already gone through cancer and it has come back. In addition, in the movie Mulan, the main character has to be strong and take her father’s place in the army to save his life. She has to be mentally strong to deal with all of the things that she may face when she goes to war. Examples of heroism are when people, whether they are real people in movies or characters out of books dedicate their lives to a quest. In the Odyssey, Odysseus goes on the quest of killing the Cyclops. He has to go on this quest so that he can protect the people in his village. He is a hero because he gave the Cyclops wine â€Å"so that he could taste the sort of drink he carried on his ship. † This shows he is a hero that goes on a quest because he had to give the Cyclops wine in order to kill him once he became drunk. Another example of heroism is Mulan the movie. In the movie Mulan, Mulan goes on a quest with the Chinese army to take the place of her father because he was too sick to fight; therefor Mulan chose to dress up as man to save her father’s life. In the passages written by Ana’s family members, they all feel that she is â€Å"strong† and that she has the â€Å"strength to carry on each an everyday. † Ana’s quest makes her a hero because even though she going through a rough patch she never gives up. Heroism is not giving up when the world around you seems as if they have given up on you. For in the poem A Man, he does not give up living his life even though he has lost an arm. He has turned this accident into a positive. He believes that â€Å"where the arm had been torn away a wing grew. † (Lines 17-18) I believe that this shows the man not giving up because he could have easily let his arm that was lost be the thing that he focuses on most every day but instead makes it a good thing. The man â€Å"set himself to do everything with twice as much enthusiasm. † Also, Ana, a cancer patient has to stay strong for her family. The only thing keeping Ana from giving up is her loving family. Ana’s daughter states that her mother says â€Å"keep going; keep going, like a giant guardian angel above the roaring crowd. † (Piece 3- lines 5-6) Lastly in Moco Limping, a dog named Moco had a dead leg. Moco wants his owner to love him as much as he loves him. â€Å"I feel his warm fur and his imperfection is forgotten. † In present day life the pop culture makes everything seem like if you don’t get fame for it then it is not important. Heroism isn’t about the fame and fortune, it’s about doing something for someone else or just for yourself; meaning that a hero is someone that is brave and has noble qualities. Being a hero can be as simple as saving one’s cat from a tree, pulling a dog out of a whole, or even fighting a deathly disease like cancer. When you have the will power and the courage to do something to help someone else or protect them you could be considered that person’s hero. You never know if you are a hero until you do something heroic. Throughout the process of analyzing these heroic qualities I have realized that a hero can be an everyday person in everyday life. If I am ever given the task to rise up and become a hero like the people and things I analyzed I hope I will have the courage like my characters did.

Stinging Nettle - Free Essay Example

Sample details Pages: 6 Words: 1866 Downloads: 6 Date added: 2017/09/21 Category Advertising Essay Type Argumentative essay Did you like this example? [pic] Stinging nettle In the hunt for new, ecologically friendly fabrics stinging nettle fiber has come up smelling of roses. Clothing made from the nettle is not a new idea; for the past 2,000 years people have worn fabrics made from these stinging plants. But nettle lose there popularity when cotton arrived at 16th century, because cotton was easier to harvest and spin. Nettles made a brief come back during the First World War, Germany suffered storage of cotton and nettles were used to produce Germany army uniforms. Now, new advance in spinning technologies and cross- breeding to produce super- high- fiber plants means that stinging nettles are set to become the latest fashion. Nettle Nettle is highly successful plant found all over the temperate areas of the world. Nettle is common herbaceous plant which regroups 30 to 45 species. It is the part of the urticaceae family such as ramie (Asian nettle, Boehmeria nivea) and belongs to the genus Urtica. The most prominent me mber of the genus is the stinging nettle Urtica dioica, native to Europe, North Africa Asia and North America. Existing the problems in the agriculture sector underline need for alterative crops. Stinging nettle is a perennial plant thrives in nitrogenous and Over-fair-sized soil and also has environmentally sound cultivation method as well as resistance to diseases and rests so they do not need dangerous pollutants to protect them. The plant itself is variable growing from 0. 6sto 2 meters plus in height and can be found in variety of habitats and soil types the stem specially of old plant of the big stinging nettle has very long and tough bast fibers. Thousands of year ago nettle thread – also called nettle fiber was produced from this plant. Further more fibers also useful for manufacture of nettle cloth, which is tougher than linen, as wall as finishing nets and rope. The single fiber of the stinging nettle can only reach the maximum of 250 millimeters could be reac hed. Nettle plants widely exist in china, but up to now there is no research regarding the Chinese nettle fiber properties it’s specially about there spinability. The average length of the nettle fiber is about 34mm, and fineness is ranging from 0. 589 to 0. 769 Tex. Nettle fiber has high breaking strength and low breaking extension and high initial young modulus. Both biochemical method and chemical method can meet the requirement of nettle degumming, with residual being less than 4. Nettle fiber can be utilized as textile material can be spun in rotor spinning machine after well degumming. Nettle fiber invention The first attempt to commercialized the production of nettle fiber was in Germany during 1720s, since there have been frequent effort in several European countries to cultivate the nettle and develop method of extracting the fiber that could be applied on large scale. Most of these results carry in Germany particularly during the 19th century. Unfortunately th ey do not seem to have been successful, cost effective method of nettle fiber extraction resulting from all this activity. It was Dr Gastav bredemann who turned the tide with his research from 1927 to 1950. He interbred selected plant of Urtica dioica and produced several high fiber clones that could be cultivated. The criteria for selected plants were that they should be frost resistant, have long straight stems with the minimal branching and of course a high percentage fiber in stem. These verities were given the name ‘Nettle’. Bredemann’s work was quickly forgotten for many years after his book DIE GROBE BRENNESSEL was published in1950. During the 1990s Dr Jens dreyer from the institute of applied Botany in H Hamburg re-identified the individual fiber nettle clones that still survived in the institute and revived and tested Bredemann’s research. The fiber nettle is now being used as a basis for several commercial nettle fiber projects in Europe and a dvance in technology are making it possible to process the nettle more successfully and cost effectively. The use of the wild nettle for fiber is still also possible. The Kalajokilaakso nettle fiber project in Finland has demonstrated this by producing a nettle fiber yarn from wild nettle that have been carefully selected and cultivated. Chemical and physical properties Research into the chemical and physical properties of nettle fiber has been taking place for the last five years. All the available information has been gathered together from projects in Finland, England and Germany and where possible a comparison has been made between the wild nettle and cloned fiber nettle. Fiber nettle can be distinguished from wild nettle by their larger quantity of individual fiber cells with the bigger walls. The plants was selected because their lack of branching from the stem they have only a few stinging hairs will lose most of there leaves in august which gives a fewer problem of bio mass in the straw. Most work on the characteristics of fiber has been done by the Faserinstitut Bremen. The individual fiber cell are composed of cellulose and held together in their groups by pectin and hemicelluloses. The shape of the cell oval to round polygonal. The oldest and thickest fiber is in outer part of the bark. The length and diameter of long fiber is influenced by the species of nettle, its level of maturity and nutrition, where is found on the plant and the method of extraction. After mechanical separation the average measurement of the length is 4-7cm and 40-50 µm in diameter. Treatment by alkali or enzymes leads to 40% fiber measuring 4-5cm long and 25% measuring 5-6cm long, when the fiber length distribution by mass is calculated. Their fineness is approximately 15-25  µm in diameter. The pure fiber content of the best cultivated nettle plants from Hamburg is about 155 of dry mass; therefore six tones of harvested dry steam would give an average yield of approximately 900 kg of fine fiber. The wild nettle is approximately 3-8% of dry mass. Fiber from nettle kwon as nettle wool due to its softness and the nature colour is cream/ white, so it is easy to apply a coloured dye to the fiber or fabric. The degree of polymerization of cellulose in the cell wall is about 2280. Nettle is strong fiber with 50cN/t, measured by the stelometer and this is important in spinning. The fiber is separated with mechanically and then with enzymes to get strengths of 23-35cN/tex in comparison to cotton fiber has strength is 20Cn/tex, but fiber is not flexible which affect spinning process. The elasticity module is much higher than banana and jute. Moisture absorption is about 11%. The fibers contain about 54% pure cellulose 10%arabinane, xylane galacturonane and other hemicelluloses. Nettle fibers contain 4% pectin. This is an important factor has to removed from the fiber to get the good and fine yarn. This removed in method of enzymatic retting . By using pectinases the pectin can be broken down thus freeing the individual fibers. |Parameter |Before retting |After retting | |Fiber strength (N/mm? |740 | | |Fiber strength (cN/tex) |50 |25-35 | |Fineness (dtex) |5 | | |Elasticity modulus (Gpa) |34. | | |Strain (%) |12 | | |Cell wall density (g/cm) |1. 1 | | |Length of fiber (mm) |40-50 | | |Cellulose (%) |54 |88 | |Hemi cellulose (%) |10 |4 | |Pectin (%) |4. 1 |0. 6 | |Lignin (%) |9. 4 |5. 4 | |Wax and fats (%) |4. 2 |3. 1 | |Water soluble products (%) |18 |2. | (Retting is treatment of enzyme to improve its properties) [pic] Nettle fiber possess extra ordinary extraordinary characteristics and properties †¢ It is very tough and is able to absorb greater deal of moisture, swell like cotton and splendor. †¢ The fiber of the stinging nettle have a special characteristic in the fact that they are hollow which means they can accumulate air inside thus creating natural insulation. To create cool fiber in summer the yarn length are twisted closing the hollow core and reducing insulation. In winter with low twist the hollow fiber remains a constant temperature. The average tensile properties of nettle are young modulus equal to 87 Gpa, a tensile strength equal to 1594 Mpa and, a strain at failure is equal to 2. 11% As from table stinging nettle fiber have a higher stiffness but lower strength and strain to failure then glass fibers. |Table 1: mechanical properties of nettle | Fiber |Young’s modulus (Gpa) |Strain to failure (Mpa) |Ultimate stress (%) |Density(g/m? ) |Average diameter (micrometer) | |Stinging nettle |87 |2. 2 |1594 |Na |20. 0 | |Flax |58 |3. 3 |1339 |1. 53 |23. 0 | |Hemp |35 |1. 6 |389 to 900 |1. 07 |31. 2 | |Ramie |20 to128 |1. 2 to 3. 8 |400to 1000 |1. 56 |50. 0 | |Sisal |9 to21 |3 to 7 |350 to 70 |1. 45 |100to300 | |Glass |72 |3. 0 |2200 |2. 54 |5to25 | | What is in the sting? The stinging structure of the nettle is very similar to the hypodermic needle although it predat es that man-made invention by million of years! Each sting is actually a hollow hair stiffened by silica with a swollen base that contains the venom. The tip of this hair is very brittle and when brushed against, no matter how lightly, I t breaks off exposing a sharp point that penetrates the skin and deliver its stinging payload. It is used to be a thought that the main constitute of the sting was formic acid – the chemical used by ants, burning sensation that demands to be scratched. Although formic acid is present in the sting, recent research has shown that the main chemical is histamine, acetylcholine and 5-hyroxytryptamine. Processing of the nettle fiber by traditional method Step1:- There are considering being a number of benefits associated with the cultivation of nettles. The nettle is a perennial and can be harvested year after year without replanting. Research has shown that nettle may be propagated by various method ; seed, seedling, cutting, and planting of rh izome pieces the advantages of growing by seed is that is a economical . The nettle plant is depending upon good water supply. Nettle needs good soil condition with sufficient supply of nitrogen and pH of 6. 5. The seedling can be planted in May with a vegetable plant when they have reached 5-6 week growth. The fiber nettle is propagated by stem cutting. The cutting required 4-8 week. The nettle rhizomes are than protected within the rigid from damage by machine. Step 2:- The shrubs are brought and the men strip them of their bark and dried for 3-4 days Step3:- The dried nettle bark is boiled with ash for 2-3 hours. Step4:- Stone washed near by river is done Step5:- Then the fiber is mixed with limestone and dried for another 2-3 days. Step6;- After this they separate the fiber from limestone and processed into threads with the help of a traditional spinner or through spinning wheel. Step:-7 Cloths are traditionally woven in handlooms. Now days, a By comparison between the fla x, hemp, ramie although the nettle stem are irregular in their size and the fiber are prone to break at the point where the stem branches. The new technology of spinning nettle fiber is not research till yet. The traditional view of nettle fiber cloth was that it was soft, hardwearing and warm to skin. The nettle fiber is mixed with other fiber like cotton, silk, viscose and flax up to 80% nettle fiber has been used in the some of blends. The fibers have been processed by retting with enzymes and selected microbes.
