What cause teenage drug abuse Miguel Diaz Saint Michaels College What Causes Teenage Drug Abuse? Nearly half of college students consume illicit drugs. A study done by Newport academy said that in 2016 , 45% of male and 42% of female college students consumed illegal drugs during their academic year. This number has been growing and growing in the last years, and doctors think that is going to keep growing. Don’t waste time! Our writers will create an original "What Causes Teenage Drug Abuse" essay for you Create order There can be a lot of different reasons why this numbers have been growing in the last years but I am going to talk about the ones that in my opinion are the most important ones. Bad parenting is one of the biggest causes of teenage drug abuse. Having trouble at home with your parents will make teenagers wanna evade from reality, and that will cause them to try new things that will cause them a fake relieve.A lot of teenagers have trouble with their parents at this age for multiple reasons, is one of the hardest ages in human live, parents are always looking for the best possible future for their kids, and tennagers just want to have fun and experience new things, they dont tend to put their priorities in college high school grades extracurricular activities jobs while parents focus on this things a lot, and this always bring confrontation between the parts. A study realized by the Pew Research Center showed that only 65% of kids in the United States live with married parents and this has been going down since 1997 when it was 68%, 21% lived with a solo mother and 4% with a solo father. This can be a big cause why teenagers start consuming drugs, having a big parental reference during the teenage age is key for the personal development of the teenagers. At this age (age between 15-20) human beings start and finish developing their personality, and if they start consuming illegal drugs is likely that they will keep doing it until their mid age. Another big cause of teenage drug abuse is curiosity, at this age all tennagers wanna try new things and new experiences and the use of drugs always knocks on their doors. Most tennagers usually start using drugs called connection drugs, that are really cheap and easy acces narcotics that will attract the consumers to the drug world, once consumers start consuming this drugs they will experiment the basic characteristics of the drugs, like highs, head rushes.. and then they will want to consume more strong ones that will cost more money and are more dangerous, this is the reason why this drugs are called connection drugs. Teenage curiosity is one of the most dangerous times in human lives, is a time where teenagers just want to experiment new things without really understanding or acknowledging the causes of them. This can also bring teenagers to another dangerous problems like for example suicide, this is why a lot of schools have started a lot of new programs and activities to prevent suicide in their communities. Another reason that causes teenage drug abuse is stress, this is a really important problem in every teenage live, school grades, getting into college, meeting your group friend expectatives, have a good reputation, being a good athlete are things that most of students care about, and when one of this things dont work the get stressed and they can react in a lot of different ways, one of them is drug abuse to relax and try to stop the anxiety and stress, a article in the Telegraph said that one of every 3 16 years old are turning to cigarettes alcohol or drugs to cope with the pressure of loming exams and coursework deadlines, a new study suggests. This numbers are unbelievably high and need to stop, because the amount of teenage drug abuse keeps growing and growing every generation and it starts sooner and sooner, in 2005 1 of every 6 tennagers used drug abuse and alcohol to evadate from stress now is one of every 3. Teenagers live a very stressful live because they are always doing activities or studying or worrying about multiple things, so in my opinion society should try to understand this and try to be a little more flexible with them, with this I mean giving them more time to assimilate things and preparate for them, in that way students are going to be able to have less anxiety and are not going to recur to this last second reliefs that drugs give them. Another reason that causes teenage drug abuse is peer pressure. None human being has the desire of being a loser or a non like person, in fact we all want to achieve good things in live and be a well known person. Teenagers groups use a lot of group pressure when they want one of their friends to do something, this is a really common way for teenagers to start smoking cigarettes or consuming drugs or alcohol. Trying to act mature and cool is a thing that most teenagers try to do to reflect that they are not little kids anymore and they are ready for the real world, a lot of older people drink and smoke cigarettes this is the reason why teenagers start smoking and drinking, and a lot of times if you are the only one in your group that doesnt smoke or drink you are going to feel out of place, or they are not going to like you the same, so everyone is going to start smoking to dont get their social image down. This is how group pressure works and thats why it is a really effective process. The teenage age is a really hard age, where teens have to find their fit and their social place,it is a age highlighted by mistakes where drug abuse is growing and growing every year for multiple causes of society. It is on our hand and responsibility to stop this causes and try to help as much as we can to our society. Together we all can stop this drug problem. Citations Correspondent, K. D.

Introduction And Executive Summary Renewable Energy
PG Assignment Report Name: Junnan LIU Student number: z5057871 Course code: SOLA 9004 Hydroelectricity Introduction and Executive Summary At the present time, renewable energy is a tendency in the whole world with consume of petroleum and the environment problem. There are a lot of reasons to let Elbawener to use renewable energy, some of them I list as follows: First of all, renewable energy is essential to Elbawener s future economic growth and prosperity in a carbon-constrained world. (Introduction of Renewable energy, CEFC, 2015) This is really a perfect thing for Elbawener. What’s more, renewable energy would help lower Elbawener s and Australia s carbon emissions, this is really good for the environment of†¦show more content†¦Because there has a large river nearby and the technology of hydroelectric is advanced and stability. I will list the details of hydroelectric for this city below. Physical Basis of the Technology So just how do we get electricity from water? Actually, hydroelectric and coal-fired power plants produce electricity in a similar way. In both cases a power source is used to turn a propeller-like piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coal-fired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same. Take a look at this diagram of a hydroelectric power plant to see the details: (Hydroelectric power, Howard Perlman, 2015) As the picture shows above, the principle of hydroelectric is very easy: The fast moving water (kinetic energy) strikes the turbine and they will start moving (mechanical energy) and then the energy is used to run electric generators, and then we could produce power what we need. There are four parts of a typical hydro-power plant which are Dams, Turbines, Generators, Transmission lines. (Beauty of Hydro-power, 2015) Dams: The dam is made on a river to collect water and also serves as a water reservoir. To make water have higher potential energy and also control the water flow through pen stocks. Turbines: Convert the kinetic energy of water into mechanical energy. The

I am also highly indebted to my supervisors Faisal Shafait and Ilya Mezhirov, who seemed to have solutions to all my problems. Author The report presents the three tasks completed during summer internship at IUPR which are listed below: 1. Detection  of  headlines  in  document  images  with  black  run lengths  and OCRopus performance evaluation in detecting headlines 2. Re engineering the zone classification module 3. Evaluation of different segmentation algorithms performance All these tasks have been completed successfully and results were according to expectations. The detection of headlines achieved a low error rate of 2. 85% as against  6. 52  of  previously  used  methods. During  evaluation  of  segmentation algorithms XY cut was found to gain a lot by noise cleanup, which is an interesting result as it strengthen the claim of XY cut segmentation algorithm as a suitable method  for  OCRopus. The  re engineering  and  porting  of  zone classification module  to  OCRopus  makes  it  possible  for  OCRopus  to  have  a  text/image segmentation if it is required in future. Author Abstract OCRopus : Introduction Though the field of optical character recognition(OCR) is considered to be widely explored, the development of an efficient system for use in real world situations still remains a challenge for developers. OCRopus is a state of the art document analysis and OCR system, featuring pluggable layout analysis, pluggable character recognition, statistical natural language modeling, multi lingual capabilities and is being developed at IUPR. This being a very big project, I was assigned the tasks of developing tools for layout analysis and evaluation. The Goals: Following goals were set as I proceeded in my work: 1. Conversion of ground truth data in MARG database from XML format to hOCR micro format[1]. 2. Development of a rule based headline detection method using the median black run length of the lines. 3. Development  of  segmentation classification  module  and  evaluation  of performance of different segmentation algorithms as against noise. 1. XML to hOCR: hOCR  is  a  format  for  representing  OCR  output,  including  layout  information, character  confidences,  bounding  boxes,  and  style  information. It  embeds  this information  invisibly  in  standard  HTML. By  building  on  standard  HTML,  it automatically  inherits  well defined  support  for  most  scripts,  languages,  and common  layout  options. Furthermore,  unlike  previous  OCR  formats,  the recognized text and OCR related information co exist in the same file and survives editing and manipulation. hOCR markup is independent of the presentation. Due to all above qualities of hOCR format, it is highly desirable to have ground truth in this format. I was assigned the task of converting the MARG database ground truth into hOCR format. For  this purpose I have written following script. Script Name : xml to hocr Language Used: Python Command line argument form: xml to hocr FILE. XML FILE. XML : The file in XML format to be converted into hOCR micro format. Note:  The  script  does  not  take  care  of  latex  characters  yet. It  would  be  an improvement to incorporate this feature. 2. Headline detection Based on black run length and its     integration into OCRopus: Detection of headlines in document images is one issue that is mostly overlooked but yet is highly desirable to properly format the output of OCR. OCRopus had till now used a rule based method which used space between lines as the criteria for detection of headlines. Though this method worked for many images, it also failed many times. It was an obvious observation that black run lengths of headlines are more than the black run length of the normal line, and we tried to build upon this concept. We used median black run length of a line as the deciding criteria. The median was used instead of mean because mean run length could have easily been affected by the noise merging with text and would have produce errors. The whole approach is simple as discussed below: 1. Calculate the median black run length for the each line on page. 2. Compare this run length for each line with the lines below and above it. 3. If  black  run length  for a  line has  been found K1(a  parameter)  times  the median  run length  of line below it, and K2(another parameter) times the median run length of the line above it,set it as a headline. The value of parameters K1 and K2 was to be found experimentally. After many times evaluating the performance of the program, the value of K1 and K2 has been set to 1. 5 and 1. 1 respectively. We used histogram based method to find the median run length. A histogram of the number of occurrences versus run length was calculated, once we have such a histogram we normalize it with the largest value of occurrence. Then we calculated the cumulative distribution function for this normalized histogram. The point when cumulative distribution function reches a value of 0. 5, corresponds to the median runlength. The  program  for detection  of  headlines  was  written  in  C++  and used  standard OCRopus classes. The program has been successfully integrated into OCRopus and Evaluation: We  also  designed  a  tool  which  evaluates  the  performance  of  the  OCRopus  in detecting  headlines. As  according  to  OCRopus  standards,  this  tool  has  been developed to work with files in hOCR micro format. This tool comprises of two programs: 1. The first program takes the OCRopus output and the corresponding ground truth file in hOCR format and  outputs the total no of false positives and false negatives which occurred in detection. It also outputs the total no of true  headlines  which are  present  in the  ground truth. The  command  line form of this programs is:
