Fahrenheit 451 essays

Fahrenheit 451 essays Fahrenheit 451 is a futuristic novel, telling the story of a time where books and independent thinking are outlawed. Books and ideas are destroyed, books are incinerated, where as ideas thinking becomes a danger to society and is not tolerated. The Hearth and the Salamander is the title of part one. The salamander represents the main character of Guy Montag. Montag's occupation as a fireman is to burn books and text to erase their existence and impact on thinking. The symbol of a Phoenix is used throughout the novel. The Phoenix was a mythical bird of ancient Arabian legend. The Phoenix symbolizes the rebirth after destruction by fire. Firemen wear a crest of the Phoenix on their uniforms. Montag, after realizing the truth of his job, opens his eyes and sees that fire and destruction has indeed destroyed his newly gained ideals, he wishes to be reborn. With his new ideas of knowledge, he goes to Faber with ideas to save the books, and he hides books in his house. Montag ev en goes as far as stealing books from houses that he is supposed to be destroying. Phoenix is "reborn" only to get burnt and destroyed, again. Like the Phoenix, Guy's life is a cycle of getting burnt and rebirth, until one time the away Montag escapes and where Montag kills Capt. Beatty by igniting him with the liquid fire. For Montag, fire has been good to serve the purpose of being a fireman. Fire is one of the only things Montag knows, and the only thing he knows as a solution is to burn the problem. Capt. Beatty has taught Guy that fire is the solution to everything, when in reality, fire destroyed books, homes, people, Capt. Beatty, Montag's house, and in the end, it destroyed the city from which Montag barely escaped. However, fire also symbolizes something else, warmth and hope. It is not until the very end that Guy realizes that fire does not have to be destructive, it is a tool which can have many uses. After meeting the othe ...

The Worst and Best Breakup Lines

The Worst and Best Breakup Lines Your relationship is not working out. You have hit a dead-end, and now your relationship is a cesspool of broken promises, jealousy, and boredom. You know that you have to end the relationship, but how do you approach this issue sensitively? If you handle things callously, you may end up with a bruised eye. If you are oversensitive, you may end hanging on to a dead relationship, feeling bitter and exhausted. Breaking up with someone is never easy. Especially, if you have been with been with that person for a long time. However, if things come to a head, and you feel it is time to move on, it is best to have a clean break up without carrying the burden of heartbreak or unspoken feelings. Saying unkind words, calling each other names, or simply shutting all communication with your partner is extremely bad ways to break up. If you expect to be in a healthy relationship, you should at least have the maturity to break up without being abusive or selfish. How Not to Break Up: 6 Worst Breakup Lines That Can Land You in Trouble If you don’t want your current girlfriend or boyfriend to become a stalking ex, or your spouse to file for divorce on grounds of mental harassment, you must ensure that the breakup does not become an ugly brawl. Also, how you express to your partner that you are breaking up with her will go a long way in restoring her faith in relationships and men. Here are six common breakup lines that can land you in trouble. 1. â€Å"It’s not you, it’s me.† This is a classic excuse when you want to avoid confrontation. Though it may seem non-accusatory, this breakup line is not fair because you don’t give the person a chance to find out what really went wrong. Worse, its usually not true: there are usually reasons for breaking up that relate to incompatibility on both sides. So what do you do, if it is really not her, but you that is the problem in the relationship? What if you mean it, sincerely? If it’s really not her, but you that is the problem, explain why thats the case. Perhaps you are truly unable to commit to a long-term relationship because you are financially insecure, or emotionally overwhelmed, or still in love with your ex. If there really is something going on with you that makes a relationship impossible at this time, don’t leave without offering a genuine explanation for the breakup. 2. â€Å"I want to take it slow.† To most people, I want to take it slow means I like you and want to pursue this relationship but at a different speed. While its possible that your partner will respond by walking away from the relationship altogether, a decent human being will see an opening to a conversation about how youd like to proceed. Do you want to get together less frequently? Slow down your physical relationship?  Ã‚   Bottom line, asking to take it slow is a great way to slow down the pace of your romance (assuming that youre in the early stages of getting to know one another). Its a poor way to actually end a relationship, and its almost certainly the wrong thing to say if youve been in a committed relationship for years! 3. â€Å"I am not ready for a relationship.† If you were not ready to be involved, what were you doing all along? Why put on a charade, and then pull the plug just when your partner was getting serious? A breakup line such as this one shows that you have no respect for your partner’s feelings. It is okay to not want to take the relationship to the next level if you are not ready. However, it is not fair that you choose to break off the relationship because you suddenly realized that what you thought was a  fairy tale romance was actually a real-world relationship with a flawed human being. 4. â€Å"Let’s just be friends.† This is the most dangerous breakup line, ever. It sounds like you are giving a compensatory reward to your partner by promising to be â€Å"friends.† Really? Do you expect her to buy that? Did you know that by promising to be friends, you are asking for trouble? Breakups are hard, and at this vulnerable moment, you might end up together on a rebound. Because, hey, you said you wanted to be â€Å"friends,† right?  If you truly continue to spend time together as friends, you may never be able to move on and never able to fully commit to your partner. 5. â€Å"I will always love you, but never like that.† Did you suddenly decide to become a saint? If you ever decide to use this breakup line, don’t be surprised if you end up with a bloody nose or an egg on your face. Why would you say that you love her when you don’t? Many people use this breakup line in the heat of the moment, hoping to diffuse the tension. However, this breakup line will always haunt you, even after you have long moved on. Don’t throw crumbs at your partner. It is not fair for you to break her heart, after leading her on to believe that you loved her. 6. Youre great, but it is really your sister I fancy. Even if this is the truth, please dont blurt it out. Some truths are best buried. You date a girl, only to later fall in love with her sister. How do you think shes going to take the news? Would she hug you and say, Oh wow! Im so happy to have you as my boyfriend and brother-in-law!? Or would she kick you out of her house and her life, the moment you utter those words? And what good would it do you to inform her that your heart flutters at the sight of her sister? No self-respecting girl would ever take this breakup line well. 9 Perfect Breakup Lines from Famous People Here are 9 famous quotes to use for breakup lines. They help to communicate the pain of breakup without seeming over the top. Use them to create your own personal breakup line. Borrow the ideas without making it clichà ©d. Let your breakup line be as memorable as your pickup line was.:   Maggi Richard Two words. Three vowels. Four consonants. Seven letters. It can either cut you open to the core and leave you in ungodly pain or it can free your soul and lift a tremendous weight off your shoulders. The phrase is: Its over. Marilyn Monroe Sometimes good things fall apart so better things can fall together. Sarah Mlynowski Just because a relationship ends, it doesn’t mean it’s not worth having. Alex Elle I’m thankful for my struggle because without it I wouldn’t have stumbled across my strength. Amit Kalantri I cannot compromise my respect for your love. You can keep your love, I will keep my respect. Judith McNaught,  Paradise Either give me your hand, or end it now, and put us both out of our misery. Lone Star I’m going to smile and make you think I’m happy, I’m going to laugh, so you don’t see me cry, I’m going to let you go in style, and even if it kills me – I’m going to smile. Fannie Flagg,  Fried Green Tomatoes at the Whistle Stop Cafe You know, a heart can be broken, but it keeps on beating, just the same. S. B. Morse,  Now and at the Hour of Our Death A broken heart is just the growing pains necessary so that you can love more completely when the real thing comes along.

Experiences and Benefits of Profound Experiential Education Essay

Experiences and Benefits of Profound Experiential Education - Essay Example The paper tells that when personal well-being is on the line people tend to lay differences aside to cooperate. At the accomplishment of a particular task, some would revert to introverted behavior while others would revel in the victory. Nevertheless, the threat of discomfort as caused by natural consequences is one good motivator to help people who are not such team players get into the habit of becoming an integral part of a group effort. We learned how to communicate effectively. Again, the impetus for the preservation or accusation of creature comforts often motives people who are not so inclined toward effective communication to delve past their own insufficiencies in language and non-verbal behavior. Those who are given to meaningless small talk in daily society find that perpetual commentary on their own thought patterns is radically unnecessary. Those who are given to silence find that in order to negotiate the path of least resistance toward a goal they must speak up from t ime to time. This is the nature of nature. It tends to bring about certain survival behaviors while quelling those that are not so helpful to individual survival. We learned to respect each other's individuality. We differed in origins. We differed in personalities. We differed physically. We differed in knowledge. We differed in skills.

Religion Journal Essay Example | Topics and Well Written Essays - 1000 words - 4

Religion Journal - Essay Example Rituals in case of Confucianism varied from being semi religious routines to the way people met and interacted with each other. As per Confucianism, the construction of a moral society depended on the extent to each individual affiliated to and abided by the salient morals. It does come out as being strange that one of the most ancient world religions like Confucianism does remain silent about the notion or concept of a higher power. It is really interesting to note that the crux of Confucian thought does tend to focus on the creation of a social moral order. However, one does wonder as to the moral order that Confucianism talks about does mean subservience to the existent order, or did it allow for original and individualistic thought and action? It is indeed interesting to note that Confucian virtues do aspire for the creation of a society where people respected one another and cared for each other. Does it leave a scope for competitiveness and personal ambition? Taoism did originate in China about two thousand years ago. Taoism does regard Tao to be the quintessential source of and the principle underlying all order in the universe. Taoism is a religion marked by both a profound sense of unity symbolized by Tao as well as the interplay of opposites marked by Yin and Yang. As far as morality is concerned, Taoism does affiliate to a relativistic view in the sense that it does belief that there do not happen to be and sacrosanct moral values, and that the morality imminent in a situation did depend on the circumstances attendant on that situation.

1,2,4-Oxadiazole Moiety Molecules Synthesis for Cancer

1,2,4-Oxadiazole Moiety Molecules Synthesis for Cancer 2.4. Synthesis of 3-(4-(6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-fluorophenyl)-5-substituted-1,2,4-oxadiazole derivatives for their MTT assay using MCF-7 breast cancer cell line and degradation of DNA in EAT cells 2.4.1. INTRODUCTION In the biological and pharmacological importance, heterocycles plays a significance role. Oxadiazole molecules show biologically activity includes angiogenesis inhibitor [246] and also HIV inhibitor [247], tyrosine kinase inhibition [45], histamine H3 antagonism [48], muscarinic agonism [49], potent histamine H2 receptor antagonists [50, 51], muscarinic receptor antagonists [53, 54], interleukin-8 (IL-8) receptor antagonists [65], cytotoxic activities [68], monoamine oxidase inhibition [66], potent therapeutic agents for prostate cancer [72], anticonvulsant activity [67], tumor-selective and apoptosis-inducing agents [70, 71], antitumor [4f] and apoptosis-inducing anticancer agents [73, 74]. Breast cancer is a most terrifying disease in which cells in breast tissue grow and divide without normal control. This type of growth of cells without control forms a lump called tumor. In breast cancer, tumors are called benign or malignant. Malignant tumors will grow by eating food. They get the food by forming new blood vessels in a process called angiogenesis. These blood vessels are the main reason to promote the growth of the tumors. After this tumor growing it will spread to nearby tissue, which is called as invasion. The breakage of main tumor cells will spread into other parts of the body and it will lead to metastatic breast cancer. This happens through blood stream or lymphatic system and this process is called metastasis. The main disadvantage of the malignant breast cancer is dividing and grows out of control which leads to form number of new tumors. If those new tumors are in other parts of the body, then also we call those as breast cancer. Especially in women, breast cancer leading to the cause of cancer related death. In developing and developed countries, breast cancer is the second most common malignancy type diagnosed disease in women. In India breast cancer is the most discussing problem in the current health problem (248). By the survey conceded by the Indian Council of Medical Research (ICMR), the percentage of breast cancer patients has been nearly doubled. In the past few years nearly one lakh new patients are being detected from 1985 to 2001 (249, 250). It has been estimated that the breast cancer in 2004 is nearly 90,273 and they predicted that in 2015 the patient’s number may be nearly 1, 12,680 (251). Due to the damage in DNA, normal cells will become cancer cells. DNA is present in every cell and it directs to all its actions. When DNA gets damaged in normal cells, the cell either repairs the damage or it dies. But in the cancer cells, damaged DNA is not repaired. The damaged cell undergoes splitting. As a result cell goes on making new cells that the body doesn’t need and those cells have same damaged DNA as the first cells does. This conjecture the design and synthesis of new anticancer drugs, and drug combination and treatment modalities is still the need for effective treatment of breast cancer patients [252]. 1,2,4-Oxadiazole moiety molecules show signs of vide variety of biological activities [40, 253-255]. In connection to the above studies, our molecules are subjected to the angiogenesis using MCF-7 breast cancer cell lines and degradation of DNA studies using in EAT cells. 2.4.2.

Biology 2.4.4.1. Culture of MCF-7 cells: MCF-7 cells were cultured with minor modification in Minimal Essential medium (Invitrogen) supplemented with 10% fetal bovine serum, 100units/ml penicillin-G, 100  µg/ml streptomycin and 1% sodium bicarbonate (Invitrogen). MCF-7 cells were obtained from Cell repository unit of National Center for Cell Sciences (NCCS), Pune, India. All cell lines were maintained at 37 °C in a humidified atmosphere with 5% CO2 [256]. 2.4.4.2. Culture of EAT cells: Animals, in vivo tumor generation and imidazole derivatives treatment Six to eight weeks old female mice were acclimated for one week while caged in-group of five. Mice were housed and fed a diet of animal chow and water ad libitum throughout the experiment. All the experiments were approved by the institutional animal care and use committee of the University of Mysore, Mysore, India. Ehrlich Ascites Tumor (EAT) cells (5Ãâ€"106 cells/mouse) were injected intraperitoneally. These cells grow in mouse peritoneum forming an ascites tumor with massive abdominal swelling. The animals showed a dramatic increase in body weight over the growth period and the animals succumbed to the tumor burden 14–16 days after implantation. 2.4.4.2.1. Isolation of EAT cells from mice peritoneal cavity and compound treatment: From the peritoneal cavity of tumor-bearing mice the EAT cells were isolated (control and treated). 2-3 mm of sterile PBS was injected in to the peritoneal cavity of the mice and the peritoneal fluid containing tumor cells withdrawn, collect in sterile petri dishes and incubated at 370C for 2 h. The cells of macrophage linage adhered to the bottom of Petri dishes. The non-adherent population was aspirated out gently and washed repeatedly with PBS. Moreover, viability of these cells was assessed and was found to be >95% by trypan blue dye exclusion. The viable EAT cells were processed for further experiments. The EAT cells (5 x 106) were treated with or without compounds of 3-(4-(6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-fluorophenyl)-5-substituted-1,2,4-oxadiazole series 4(a-e) and incubated at 370 C for different time interval or for known period of time. After the incubation period the cells w ere used for the further analysis [258]. 2.4.4.2.2. Cell count by Trypan blue dye exclusion assay. EAT cells were treated with different concentrations of 3-(4-(6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-fluorophenyl)-5-substituted-1,2,4-oxadiazole compounds 4(a-e) at various time periods (0–4 h). Cell viability was assessed by mixing aliquots of cell suspension with 0.4% trypan blue and counted using heamocytometer. Cells that picked up the dye were considered to be dead [259(a)]. 2.4.5. Result and Discussion 2.4.5.1. Chemistry Synthesis of the key intermediate (Z)-4-(6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-fluoro-N-hydroxybenzimidamide (2) is outlined in Scheme 1. Briefly, hydroxylamine hydrochloride and sodium carbonate was taken in water and stirred. 4-(6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-fluorobenzonitrile (1) was dissolved in ethanol and added to the reaction mixture. The presence of –NH2 and =N-OH proton peaks NMR spectra indicates the formation of (Z)-4-(6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-fluoro-N-hydroxybenzimidamide (2). The key intermediate compound (2) was taken in dry dichloromethane and cooled to 0-5 0C, and N,N-diisopropylethylamine was added. Stirred for 10 min, then different aromatic acid chlorides 3(a-e) was added drop by drop. The reaction mixture was allowed to room temperature under stirring for 5-6 h and after that the steps forward of the reaction fusion was examined by the thin layer chromatography (TLC). After reaction completion, the solvent and th e product was separated in vacuum pump under reduced pressure. Then the product was poured to water and extracted with ethyl ethanoate. The organic layer was washed 2-3 times with distilled water to get target 3-(4-(3-(1H-imidazol-5-yl)propyl)-3-fluorophenyl)-5-substituted-1,2,4-oxadiazole 4(a-e). Upon completion crude products 4(a-e) were obtained with a good yield of 81–93% and which the product was purified with the help of column chromatography over silica gel (60-120 mesh) using hexane and ethyl acetate (1:1). The absence of –CO proton peak in synthesized derivatives in 1H spectra confirmed the identity of the products. The details of chemical structures, physical data and purity of compounds are given in Table 1.

MTT assay: The MTT assay was performed according to the protocol previously reported [257]. MCF-7 cells were plated at a density of 1 X 105 cells in 96-well plates. (Subsequently, the 3-(4-(6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-fluorophenyl)-5-substituted-1,2,4-oxadiazole series 4(a-e) were assayed using concentrations from 0.05 to 0.5 mM). After 24 h of incubation, 10  µL of 5% 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) (Sigma Aldrich) (0.05 mg/mL) were added to the culture medium. After 4 h at 370C the culture medium was removed and 200  µL of DMSO were added to dissolve the salts of formazan. The absorbance was measured with a 96-wells plate spectrophotometer at 570 nm. The experiments were independently performed three times and each experiment contained triple replicates. Control samples containing a complete culture medium devoid of cells or control cells with 0.1% DMSO were also included in each experiment. Figure 1.

DNA fragmentation assay: EAT cells were collected from mice treated with or without 3-(4-(6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-fluorophenyl)-5-substituted-1,2,4-oxadiazole series 4(a-e). Thein vivo and DNA was isolated using the phenol–chloroform method. In brief, cells were lysed in a buffer containing 50mM Tris–HCl, pH 8.0, and 0.5% SDS, and incubated for 30min at 37 °C. The cell lysate was subjected to 8M potassium acetate precipitation and left for 1h at 4 °C. The supernatant was subjected to phenol/chloroform/isoamyl alcohol (25:24:1) extraction and once to chloroform extraction. DNA was precipitated by adding 1:2 volumes of ice-cold ethanol. The precipitated DNA was dissolved in 50ÃŽ ¼L TE buffer (pH 8.0). The DNA was digested with 20ÃŽ ¼g/mL RNase at 37 °C for 1h. The DNA was quantitated and equal concentration of DNA (25ÃŽ ¼g) was resolved on 1.5% agarose gel, viewed under UV light, and documented using BIORAD gel documentation system Figure 2 [259(b)]. Figure 2. The DNA degradation of compounds 4(a-e) in Ehrlich Ascites Tumor (EAT) cells. Conclusion: A series of 3-(4-(6,7-dihydro-5H-pyrrolo[1,2-c]imidazol-5-yl)-3-fluorophenyl)-5-substituted-1,2,4-oxadiazoles 4(a-e) has been synthesized by using simple synthetic procedures and were screened for their MTT assay using MCF-7 breast cancer cell line and degradation of DNA in Ehrlich Ascites Tumor (EAT) cells activity. All the final compounds exhibited good in all the in-vitro activity.

Tda 2.2 Safeguarding the Welfare of Children and Young People

Lorraine Bale TDA 2. 2 Safeguarding the welfare of children and young people 1. 1 United Nations convention protection of children’s act- when was the 1st legislation impacted. It was drawn up in 1989, but the United Kingdom decided on 16th December 1991 formally agreed to make sure that every child has the same rights listed in the convention. Signed 20th November 1989 Location New York Effective 2nd September 1990 Condition 20 ratifications Signatories 140 Parties 194 Depositary UN secretary general Languages Arabic, Chinese, English, French, Russian and Spanish The convention generally defines a child as any human being under the age of 18, unless an earlier age of majority is recognised by a countries law. How legislation effect’s our work without children It effects our work as to making sure that all children are treated equally as it’s an obligation to prohibited and eliminate corporals punishment & all other cruel or degrading forms of punishment. Doctors Teachers Social workers Educational staff Speech therapists The children’s act of 2004- Added to and strengthened was raised to clarify the rolls of councils and other agencies in safeguarding & promoting the welfare of children in their area. Section II in the act places a duty on partners such as the primary care trust (PCT) and the police to make legal arrangements to ensure that functions with regards to need to safeguard and promote the welfare of children. It also required all children’s services authorities to establish a local safeguarding children board with legislation guidance published in 006. -Every service plays its part. – The children act 2004 was introduced following high profile enquires into safeguarding children & young people. – The acts aim where to achieve positive outcomes for the children & young people & their families. 1. Improving & integrating children’s service 2. Promoting early intervention 3. Providing strong leadership 4. Bringing together different professionals in multidis ciplinary All agencies working together^ Original children act 1989- Children’s act sets out what local authorities & courts do to protect children In charge- responsibility Local authorities with the duty to investigate if they have reasonable cause to suspect that a child who lives or is found in their area is suffering or is likely to suffer significant harm. Local authorities were also charged with a duty to provide services e. g. schools children in need. Aims 1. To bring together private & public law in one frame work 2. To achieve a better balance between protecting children & enabling parents to challenge state intervention e. . local authorities 3. To encourage greater partnership between statutory authorities & parents 4. To promote the use of voluntary arrangements 5. To restructure the frame work of the courts to facilitate management of family proceedings Lord laming= the laming enquiry is a r eport of under pendent statutory enquiry following the death of Victoria Climbie 1. 2 Work settings- No matter what setting a child is place d in that whole workforce will have some kind of role to play. The workforce will be responsible in making sure that the child is in a safe & happy environment they will need to make sure that the health & safety regulations are in order in making sure the child is a healthy & happy child that the child is not being bullied, put in danger or abused in any way by anybody and if the child is being abused by a parent for them to tell a member of staff they can trust and if its a member of staff to go to the next higher person in charge and then if you feel like nothing is getting done you should contact social services. They are also in charge of making sure that if a child is sick that the child should be removed from where any other child could come in contact and then to contact the child’s parents/carers. G. P- A GP’s role is to see children when they are ill or if they have maybe minor injuries. They will usually check the child and do a diagnosis so if the child has any bruises or cuts or if the child attends the GP quite regularly for similar symptoms they then may think there is something more behind the reason and would then maybe involve another person e. g. social services. Local hospital services- E. g. Accident & emergency units may have children that are brought in for maybe vomiting or injuries on the body the A&E staff may feel these injuries are from something more serious and would then call in social services to look into these problems and then take things further if necessary. 2. 1 Some signs and symptoms of common childhood illnesses are: -Temperature -Runny nose -Sneezing -Vomiting -Diarrhoea -Fever -Aches & pains -Itchy rash -Cough -White spots in mouth -Swollen glands -Cough with whooping sound -Loss of energy . 2 If there are children or young people that are ill or injured you would 1. Check the Childs injury or try to diagnose the illness through symptoms in case they are contagious or life threatening. 2. You would then separate the child from all other children/young people. 3. Then you would inform a senior member of staff who would then take the decision weather to call for medical assistance and parents while the above is going on about the child would need reassuring and comforting. Also make sure the children that were around the accident are reassured. Then if you have the authority you would fill out an accident or medical report. 2. 3 Some of the circumstances when children and young people may require urgent medical attention: -Unconsciousness -Injury to the head -Vomiting -Unable to breath -Broken bones -Allergic reaction -Continuing high temperature -Continuing diarrhoea 2. 4 Fires- First make sure that all children evacuate the building safely always try to close doors & windows but do not leave any children unattended, when safely away from the building then do a role check to double check all children are safe & present. You would then dial 999 and ask for a fire brigade when they respond state in a clear voice that your work setting is on fire giving them the precise address, do not hang up the phone until they have repeated the address to you then stay in a safe place with the children reassuring comfort in them. Security incidents- The first thing you would do would be to check the identity of the person trying to gain access. Refuse access of anyone you are unsure of. If they have a legitimate reason for entering make sure they sign in on the visitor’s record and sign out when they leave. Never leave them alone with any child/young person at any time, unless they have the authority to be left alone. If there is any suspicious behaviour or the person refuses to leave the premises then the police must be called in case it poses any danger to children or staff. Missing children or young people- 1. You would identify the child that is missing 2. You would then find out where the child was last seen 3. You would then conduct a search within the work setting and if unable to locate the child you would then inform a senior of staff and raise the alarm 4. The next step would be to inform the police and parents 5. You would also maybe start an organised search around the local area and parks. 3. 1 Identify the characteristics of different types of child abuse- -Undernourished -Lack of cleanliness -Bruises & cuts/self harm -Clothes that are dirty, have holes and are too small to wear -Uneducated -Constant hunger -Withdrawn -Delayed development -Poor social relationships -Low self esteem -Try to be perfect at everything & then over react when someone criticises them -Lack of medical attention Sexual knowledge that is inappropriate for a child of a young age 3. 2 Describe the risks and possible consequences of children/young people using internet, mobile phones and other technologies- When children/ young people are using the internet unsupervised they could log on to something that is for adults only which means they could be exposed to something they shouldn’t be. They could also be bullied on the internet e. g. social networks o r by texts calls on mobile phones which could eventually cause them to get depressed and harm themselves or even commit suicide. The internet could also out them in danger as they could think they are talking to someone their age but may be a man or women who they may arrange to meet with which could have serious consequences. There are also games which has violent scenes in which could end up hurting someone else thinking its ok as its just a game and could end up getting them into serious trouble. The consequences to these are they could end up: 1. Putting themselves in danger 2. Commiting suicide 3. Seriously hurting someone else . Getting put away/taken away from family 5. Being kidnapped 6. Being sexually abused 3. 3 The actions you would take in response to evidence or concerns that a child/young person has been abused, harmed (self harm) or bullied or maybe at risk of these things. If a child come to you in secrecy to tell you something, you should first never ever promise to keep it a secret or that you wont tell anyone, as this could upset the child who would end up never trusting you or anyone again. As a carer you have to understand the principles of the confidentiality boundaries and know when it is necessary to share them, having to tell someone you would go straight to your line manager who then would take the responsibility or making sure that the child protection policy will then be put in place to protect the child. If you see nothing is done you would then go to your line manager and tell them again and make sure you make notes including days & times in case nothing is done again. If nothing has still not been done about it then go to someone who you could trust, maybe someone who may have higher authority than you. It wouldn’t be good practise to go to social services yourself as you might not know the full story. 3. 4 The actions you would take in response to concerns that a colleague may be failing to comply with safeguarding procedures harming, abusing or bullying a child or young person- If you suspect a member of staff is involved you would talk to another senior member of a staff who works in your setting but if you feel you cant trust them then go to another member of staff you can trust but make sure the information you give is accurate and acted upon e. . if a child is overweight and has a cleanliness issue, and a member of staff won’t interact with them and calls them sarcastic names you would then tell the member of staff who you trust who would then take the appropriate action to having this dealt with by contacting the right safeguarding agency for that issue. 3. 5 The principles and boundaries of confidentiality and when to share them- Confidentiality is very importa nt in safeguarding the children and in doing this you have to follow rules & regulations within the workplace. It is important to understand that if a child or adult tell you something you should only tell the necessary people/person that needs to know. You should never discuss any information about the children outside your setting or to another member of staff unless a need to know basis. Any of the information on the children should always be locked away and only be shown to the appropriate people who need to see e. g. parents, OFSTED, make sure the cupboards are always locked for no one else to see. If anyone who is unauthorised see’s the information, this could cause some serious consequences.
