Hello, I am looking for someone to write an essay on Youth and Anti-Social Behaviour. It needs to be at least 1500 words.
Download file to see previous pages…
Alcoholism, drug abuse or substance abuse, sexual abuse, violence, cybercrimes etc are growing among the youths which are a matter of concern for the sociologists and the government. Morality and ethics are rapidly diminishing subjects in our society at present which encourage the youths to engage in all sorts of antisocial activities without a second thought. The life philosophies of the youths in the 1980’s or 70’s and that of the youths of the 2010 are entirely different. Because of the changing perceptions about life, youths create lot of social problems in different forms which is discussed briefly in this paper. What is social problem? “A social problem is a condition that at least some people in a community view as being undesirable” (What is a social problem?, n. d). It is difficult to define social problem accurately or comprehensively because of the various dimensions associated with it. Murder, violence, theft etc are accepted by everybody as social problems. However, teenagers who play loud music in a public places may not view it as a problem, even if it causes disturbances to the public. Smoking is also a personal matter. but if it performed in a public place, it can cause immense damages to the health of the people around the smoker. Same way, drug and alcohol abuses are personal matters. but these things can lead the abuser towards antisocial activities. …
Anti-social behaviour doesn’t just make life unpleasant. It holds back the regeneration of disadvantaged areas and creates an environment where more serious crime can take hold (What is ASB? n. d.) Man is a social animal and hence it is difficult for him to lead an isolated life. Since we are living in a society, it is necessary for us to satisfy the needs of the society along with satisfying our own needs. At the same time, individual needs should never cause any problems to others in the society. In other words, an individual need become a socially accepted need only if it does not cause any physical or psychological problems to others. For example, sex is a biological or psychological need for all the living things. Sexual engagements are socially accepted, only when both the parties did perform it based on mutual consent. However, rape cannot be justified under any circumstances because of the absence of mutual consent in such cases. Moreover, sexual activities of minors are unacceptable to the society even if it performed with mutual consent. In short, same activity can become a socially accepted or rejected one based on the circumstances or the nature of the activity. Alcoholism and drug abuse are some other major antisocial activity undertaken by youths. These things are considered as personal matters by many of the youths. However they are forgetting the fact that alcoholism or drug addiction may result in severe mental, physical and social problems which may affect others as well. Alcoholism and drug abuse can create lot of social problems such as Divorce, loss of employment. domestic violence, drunk driving etc.

Hello, I am looking for someone to write an essay on Zumba Fitness. It needs to be at least 1000 words.
Zumba Fitness
It has been accepted in most societies due to its flexible programs that can suit the most workers. Zumba fitness has been rated among the Worlds top ten fitness programs based on the number of participants and product uniqueness.
Zumba is a dance and aerobics fitness course that was started in the 1990s by Alberto Perez (Perez, 2009). He is from Columbia and started the Zumba program due to his passion for dance and music. The Zumba fitness brand consists of various products launched since 2003. They include Zumba Stape, Zumba Toning, Zumba Sentao, Zumba Kids, Zumba Toning among others. The products cater for various people in the society despite their ages.
Since Alberto is a choreographer and a dancer, the fitness program incorporates music in its sessions (Perez, 2009). Zumba uses music genres such as Salsa, Samba, Martial arts, Soca and Hip hop. The different rhythms from the music can be used to change the used approaches. Moreover, the use of different genres ensures that its customers can join the program irrespective of their music preferences.
Zumba fitness programs became popular in Columbia and there was a need to cause awareness into other countries (Perez, 2009). With the help of entrepreneurs, the program became international where it has been practiced in more than 180 countries globally. Perez had business ties with the United States. he was able to market his dance into the country. According to recent research, more than 10 million people take weekly classes. Zumbas success has been caused by its use of music and use of infomercials to cause awareness.

Hello…
I am needing assistance with this question. Trigonometry is difficult for me to follow but I really
am trying to learn this. Could you help me with the calculations, screen shots of graphs, labeling of the axes and scales. Below, directions say I need an explanation of 1-6. Please help! and thank you very much.
The directions clearly say create 2 transformed trigonometric graphs. I need good, clear examples so that I can see how this is done so I can do my own correctly. I think I need a bit of “hand holding” here because I feel a bit uneasy on my own. This is all I have been provided or I would have given you more. I apologize, this is all I have. I feel a bit fearful and uneasy with this assignment because I am so unsure and that’s why I reached out for experts to help.

Hello I am not sure what I am doing wrong. The question is “You think a coin is biased and will come up heads more often than it will come up tails. What is the probability that out of 22 flips, it will come up heads 16 or more times? (Write your answer out to at least three decimal places.) “
I keep getting the answer .0241 since I add 0.006279+0.01779 together. But the correct answer is p = .0262.

Hello, I am stuck designing a finite state machine that detects a specific 8-bit sequence (10100001) and when this sequence is detected the output of the circuit is 1 otherwise it is 0. The circuit has 2 inputs a logic 0 and a logic 1 input that enters the corresponding digit into the circuit. The tricky part is that after 16 bits are entered that don’t match the needed sequence (10100001) the system shuts off until the reset button is pressed. I also can’t use registers.Here are some more guidelines:There is no actual clock- the release of the push button (the 1 and 0 button) produces the transition that is used to trigger the flip flops (much like a clock would).Hint: You might put the outputs of the two push buttons into asynchronous inputs of a flip flops. The output of this flip flop is then used as the actual “input” value.I have started working on this problem, but where i run into trouble is the reset section as well as the asynchronous clock function. I need the circuit for this problem so then I can see what I did wrong and learn from there. An answer with some explanation would be helpful! The Due Date is final, I need time to study for the final and I can’t stay up late waiting for explanation. The price however, is negotiable to fit within the deadline. If you need any other information please let me know, I will be working on this all day anyways so I will be available.

Hello,
I am stuck on these reactions:
#1 Which mechanism is correct for AlCl3? I have seen both mechanisms used, but I am not sure why one is favored over the other for certain reactions.
#2 & 3: I am not sure which resonance for each reaction is the correct one. Can someone explain which resonance is the correct one to use when reacting the diene with the dienophile and why?
Thank you!
