Emma s View Of Love - 1219 Words

Emma Bovary allows herself to be destroyed by the people she encounters and her obsession with falling in love. Emma is not happy with herself and her relationship so she looks for other people to fill the void. Emma never really realizes that she is the root of all of the troubles in her life. If she were more in touch with reality, she would realize that she needs to work on herself before blaming her love interests for not being like the men that she has read about in the past. Emma has a very unrealistic perception of love. Emma is unable to fall in love with anyone because she will always be dissatisfied. She destroyed her own marriage before it even started because of her preconceived idea of love. Charles is absolutely in love with Emma and would do anything for her but she does not feel the same way about him due to her fairytale idea of love. It seems as if she is not capable of separating her real life romances from the romance novels that she read when during her time at t he convent. In Gustave Flaubert’s novel, Madame Bovary, Emma Bovary is unknowingly a slave to her desires. Emma is so infatuated with the thought of falling in love that it causes her to experience many problems in every aspect of her life. For example, Emma is married to Charles Bovary, however, she is not particularly in love with him. Most people get married because they are in love with each other and want to spend the rest of their lives together. Nevertheless, the thought of spending theShow MoreRelatedLiterary Analysis Of Emma By Jane Austen1648 Words   |  7 PagesAnalysis of Emma by Jane Austen In Jane Austen’s novel, Emma, protagonist Emma avoids her own transformation by her attempts to transform others.

Impact of Social Media on Mental Health - Free Essay Example

Sample details Pages: 5 Words: 1567 Downloads: 3 Date added: 2019/04/10 Category Society Essay Level High school Tags: Social Media Essay Did you like this example? Technology. Are we better off with it or without it? Can we keep up with the problems that it causes? These are the questions that are on everyones mind, especially those of us who deal with adolescents. Those of us who basically grew up last century (1950 1980) saw a lot of changes in technology. Those changes for the most part were ones that made daily life better. The television, computers, the internet, and different parts of the medical field (surgery, patient care, psychology / psychairy) to name a few. What people did not realize were the issues and problems that technology could bring about mainly with adolescents and their mental health. An article in the New York Times points out that texting, which can be incredibly distracting, can take a toll on a teens mental health. From a study done by Pew Research Center, teens are texting over 50 texts per day, and one third of teens are texting 100 or more per day. One in seven teens send more than 200 texts. Its easier, they say, to text than to make a phone call. Todays technology is growing in leaps and bounds, much faster than it was during our childhood. Now we have so much social media Facebook, Twitter, Instagram, and Snapchat that it is hard to keep up with it. Don’t waste time! Our writers will create an original "Impact of Social Media on Mental Health" essay for you Create order When we were teenagers and we had a problem at school or with friends namely bullying it was usually dealt with quickly (either a physical or verbal fight or our parents meeting with the other teens parents or the school getting involved). Nowadays, it is not face to face bullying. Now the bullying is done on social media where the ENTIRE world is made aware of what is going on just down the block. This is where technology causes massive problems. Since, when social media is used, the person spreading the negative information or comments is sitting in front of a computer or looking into the screen of a smart phone and it doesnt feel real because they are not seeing the impact or hearing what their comments are having on the other person. This is where it is very easy misinterpretations to happen. You dont know whether the person is serious or just being sarcastic something that you can if you are face to face. Nowadays, what with all the positive / negative technology that is available to teenagers, we as adults are having a hard time keeping up with it. While we are better equipped to handle most of what is thrown our way via social media due to our more developed coping mechanisms, teenagers are not able to do the same. What we had growing up (TV (7-9 channels) music (8-track, cassettes, vinyl records) was not necessarily instant gratification. Maybe according to our elders it was (since they had even less technology), but it is nowhere near what adolescents are facing today. Again, while we were teenagers, we had to wait for something (new electronics, new clothing, latest cellphone, a TV show we wanted to see and if we missed it oh well). Most of the technology now is basically an individual person using it and not a group, which leads to losing social skills. Todays teenager has a lot to deal with especially the negative impact of social media. They may deal with low self-esteem, depression and anxiety; a lot of which is normal in a teenager. But this is exacerbated by the immediateness of the different things that are posted on social media. They also deal with sleep deprivation which also affects their mental status as well as their academics. Think back to when you were a kid. You would lie in be reading a book under the covers with a flashlight so that your parents wouldnt know what you were doing. Imagine a never-ending book social media something that you cant put down because of the fear of missing out (FOMO) the next post, tweet, etc. Unfortunately, some teenagers havent made the connection between why they feel bad to what is happening online. And then to make matters worse, they dont tell their parents or guardian, who normally would find somewhere where the teenager could seek help (mental health provider). They in stead either seek out their friends, or in most cases a stranger online, which brings them right back to the problem not the solution. What teenagers have a hard time doing is separating fact from fiction. We as adults also have a hard time doing the same thing, but I believe that we are more prepared to do it. Many teenagers may suffer from the grass is always greener on the other side. They read the different profiles that are up in social media and they believe that this is the truth of the person who posted it. They have no way of knowing if this is true or if this is just something that someone posted to make themselves better than what they are. Thats how so many pedophiles and stalkers get what they want. They post a picture of someone that does not even remotely look like them. They create this whole persona with like and hobbies, address and school that the adolescent cant check (or doesnt want to). Slowly they reel them in and then just dare them to meet somewhere so they can really get to know each other. There has also been a rise on stalking, pedophilia, kidnapping, etc. Mental health providers are having a difficult time trying to make their teenage patients believe that everything that is posted is not necessarily the truth. Adolescents feel that if its posted then it has to be true. Plus, with the rising cost of insurance, many parents cannot provide their children with extended therapy. What many of the providers are suggesting is that parents get more involved with their childrens daily lives by having dinner together, shutting off technology for the weekend, checking their work from school, asking questions to ascertain if there are any problems can be nipped in the bud, have parents or adults explain that everything they read is not necessarily the truth. Teenagers have an intense need to be accepted by their social peers. And if they have to exaggerate to do this, then so be it. The only problem is that if they are caught in this lie not just the immediate area friends find out but the whole world does so as well. Many teenage girls have body issues due to the perfect ones they see on Twitter, Snapchat, Instagram and Facebook. Some mental health providers have suggested that we as parents limit the use of technology to a couple of hours daily. Easier said than done. When some teenagers have their internet usage limited, some actually have anxiety attacks. Their phone is like an extension of their body and they cant seem to comprehend the need to disconnect from it. They feel that if they are not paying attention to it continuously then they are missing out on something important. This has been labeled as Internet compulsion since teenagers are unable and unwilling to stay of any form of social media. This affects the same part of the brain that causes gambling, drinking drug addiction. The insidiousness of an addiction to the internet is that you develop more of a mental dependence to everything online. Researchers have also linked compulsive Internet use to a range of mental healt h concerns including mental ill-health, low self-esteem, loneliness, depression, social phobia, and even suicidal thoughts. There has been a rise of teen suicide due to excessive use of the internet, what is written on social media and bullying. A number of studies have found associations between increased social media use and the aforementioned issues in addition to sleep problems eating concerns and teenagers giving in to peer pressure. The cyberbully starts a systematic abuse of the teen. The same way that the teen cannot see who is on the other side of the computer, the cyberbully does not see that what they are saying is being said to a real live person that may or may not be taking what they say as truth. An analysis by the Centers for Disease Control and Prevention in August found the suicide rate among teenage girls ages 15 to 19 hit a 40-year high in 2015. Between 2007 and 2015, the rates doubled among girls and rose by more than 30 percent among teen boys. There has also been an increase in bullies using social media to egg on their victim to committing suicide or carry out a harmful act. Another problem that adolescents face is that they have no one to talk to because their parents are at work all the time to make ends meet, they are responsible for younger siblings, chores that their parents leave for them, they are part of a single parent family, etc. So, adolescents, without knowing who is on the other side of the computer, confide in someone who shows them that they have time for them. There are also some mental health apps available that teens confide in, but these apps give a cookie cutter diagnosis every teen with problem A can be helped by doing B. This is not always the case. Teens are individuals, with individual needs and problems. Parents must listen to what their children are saying and what they are saying by their behavior.

Pollution And Its Effects On The United States - 1036 Words

Hazardous Pollution Water Pollution has been an increasing problem over the last few years. Pollution comes from many different things; agricultural, urban runoff, industrial, sedimentary, animal wastes, and leeching from landfills/septic systems just to name a few (Resources). The reason why pollution has increased over the years is because the rise in population and the advancements in technology the society has made. If society plans on having their resources here for many years to come they are going to have to make some drastic changes in the way they treat the earth, and these changes will have to start with their pollutants (Foundation).

It runs one hundred eighty†¦show more content†¦Home to 10 million hogs, North Carolina is the number two producer of swine in the United States. Swine produce about ten times the fecal waste of an average human being, resulting in roughly thirteen million pounds of w aste per day from the North Carolina herd (Smith Jernigan). Research has found that hog and poultry feces and urine are leaking out of open-air, unlined cesspools, draining off the waste disposal fields used by the facilities and polluting the Tar River. Samples have shown that fifty-eight percent of watersheds have shown swine or poultry manure effects (Henderson). In addition, the large corporations behind this industry will not be liable for mismanagement of animal waste and the harm it causes public health and the environment. The corporations may own the hogs and the feed, but they do not take ownership of the waste. â€Å"The waste, and its liability, becomes the problem of the contract growers and the state of North Carolina. Until the corporations are held accountable for externalizing the true cost of their business to the public, hog lagoons and spray fields will continue to plague eastern North Carolina for a very long time† (Foundation). Polluted storm wate r runoff, including sediment from poorly maintained construction sites, is the number one reason for poor water quality in North Carolina.

Long Distance Wireless Network-Free-Samples-Myassignmenthelp.com

Questions: 1.Different antenna, such as yagi, horn, and celluar antennas, etc. has different merits. Research these technologies in details and pay specific attention to how they are used as well their strengths and weakness 2.Compare and Contrast the multiplexing techniques CDMA and FDMA in the area of wireless networking? Answers: 1.An antenna is the component of the microwave link that interrelates with open space. It is the structure that conveys the electromagnetic energy from open space into transmission lines and vise-versa (Mishra, 2007). Antennas are made and designed in different shapes and sizes according to frequency requirements. Horn Antenna This microwave antenna is also called open waveguide. It operates as a feed component for huge radio astronomy, communication dishes and satellite tracking. A horn antenna is a hollow antenna which is used to properly match the waveguide to a large radiating aperture by shaping the movement little by little. The horn antenna is mainly used for broadband signals. Advantages of horn antenna include broadband application, high gains (10-25db), simple to design and excite and it is also easy to construct (Kumar Shukla, 2015). Disadvantages of horn antenna include diffraction at the edges and low cross polarization level. Yagi antenna Yagi-Uda antenna is a high directive antenna. It consists of an array of parasitic components which are kept in parallel to the driven components. The driven component is half wave dipole antenna and the parasitic components are metallic rods of longer and shorter length relative to resonant length. The parasitic elements of longer lengths are inductive and are used as reflectors while the parasitic elements of shorter lengths are capacitive and are used as directors. Some of the advantages of Yagi-Uda antenna include high gain capability, low cost and ease of construction, and the radiation pattern of a Yagi-Uda antenna is unidirectional. Among the disadvantages is that to acquire high gains, the antenna can become very long. In addition, the gain is limited to around 20dB for a single antenna (Poole). Cellular antennas Cellular networks mainly use smart-antenna technology. The smart antenna array consists of an array of antenna elements. Some advantages of smart antenna include; wide radio coverage through range extension, increased capacity, and mitigates fading in multipath environments. In addition, it is possible to achieve maximum data rates while using smart antennas. In the future, the dominant player for medium and long distance wireless links is likely to be the smart antennas. This can be supported by the fact that Their radiation patterns help adaptively to maximize communication quality. Along with Space Division Multiple Access (SDMA) technique, they enhance beam tracking in mobile communication They ensure greater efficiency and increase frequency reuse in cellular environment The system capacity can be increased using interference reduction on the downlink and interference rejection on the uplink. Hence, for better coverage, reduced interference, reduced fading under multipath effects, smart antennas are highly appropriate and likely to be the prevailing player in the future of medium- and long-distance wireless links 2.Comparison and contrast on multiplexing techniques CDMA and FDMA in the area of wireless networking. Multiplexing is the method through which numerous signals are pooled into a single signal domain (Haas, 2014). The signal is then taken apart into the original signals on the receiving end. Multiple Access applies multiplexing techniques to separate the information of individual entities in one common signal domain. Among the multiplexing techniques are CDMA and FDMA. Code Division Multiple Access (CDMA) depends on the spread spectrum where all users can broadcast in the same frequency band at the same time (Dorf, 2015). However, each transmitter-receiver pair employs a particular spreading waveform for demodulating the information. The spreading waveforms of different users have very low cross correlation which is why CDMA is inherently interference limited. Frequency Division Multiple Access (FDMA) is the frequently used multiplexing technique. Channel bandwidth is subdivided into non-overlapping sub-channels. Each channel is then assigned the frequency slot or band permanently. All users can transmit their information simultaneously over the band allocated to them. The bands are separated from each other by guard bands which are essential to steer clear of inter-channel interference. Comparison between CDMA and FDMA multiplexing techniques Parameter FDMA CDMA Technique Overall bandwidth of a channel is shared by multiple users The time as well as the bandwidth is shared by multiple users Interference effects neighboring frequency bands interference is produced because of non-linearity of satellite transponder amplifier Performance is affected because of neighboring time and frequency slots. However, due to frequency hoping the effect is less. Code word No code word is required Code words or signature waveforms are required to demodulate the information. Power efficiency Power efficiency is reduced Full power efficiency is possible Guard times and band Guard bands are required Guard times and bands are both required References Dorf R. C. (2015).

As we all waited in line to go... free essay sample

As we all waited in line to go into the concert, there was a thrill of excitement in the air to see the performances; at The City College of New York. It was March 15th and the weather was moderate. As we gathered in the Shepard Hall there were many people seated and the performers were set on stage in formal attire. Although the place was packed, the feel of the atmosphere remained calm and relaxing. There was a pleasantness and ease about the whole performance. When the time came for the show to begin, everyone was at full attention and ready to be amazed. It was a very distinctive experience that was new to me but familiar to most. However, Professor Carey indulged the audience with her piercing vocals. The string quartet and pianist accompanied her with pieces composed by: Steven Rosenhaus, Ellen Mendel, Betty Rose and Duke Ellington. There were many different elements of music that I noticed that were being performed. We will write a custom essay sample on As we all waited in line to go or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The first piece, Madams Three Callers composed by Betty Rose accompanied by a cellist was a very confusing pieces due to the melodic lines switching at least 4 different ways. A feeling of the diatonic chords was non-existent in this distinctive piece. It seemed discordant to many, especially myself, which never heard this piece and had no understanding of the title. The composition of the pieces seemed confabulated as if there was so much to say but it was slit into different sections. At times, while listening it sounded as if the cellist strings were a bit unstable which made the melodic lines a bit obscure and left me quite puzzled. This composed piece by Betty Rose was in spired by the written work of Langston Hughes called Madams Calling Cards. Those who are used to listening to this type of music would understand the emotion within each section of each the piece. Each chromatic note reminded me of a piece I heard some time ago from a blue ban, but I could be wrong. There was a unique part where the cellist emulated the sound of a person knocking door by knocking the base of her cello, which was extraordinary. The notes increased in intensity when she slid her hands down the strings to change the chords. Although the intensity and the tempo increase, other characteristics of the music remain somewhat the same. We approached another piece by composer Steven Rosenhaus Thirteen Ways of looking at a Pigeon, another unique piece in textures of music. Professor Carey elaborated about the basics of this piece and awareness of Steven Rosenhaus perception on peculiar pigeons in nature. The transcendent concept of this piece gives a sense of eclectic musical ideas to the audience. The soothing opening movement of pianist and the string quartets synced together harmonically within the notes and created a graceful embellishment to the piece. As the movement came to an end the authentic beat was quite paradoxical within all movements, yet pleasing to ones ear but seemed unfinished. In the first movement the pleasant sounds of the notes were staccato. In the fifth movement Carey ended the piece but imitating the sounds of a pigeon by hooting. Each movement was surprisingly different in its own way. Within the eighth movement I noticed it was written in a minor key. The rhythm wasnt bad either, it felt like a piece Ive heard but they twisted it a bit. My imagination began to stir, and I realized that music of today are sampled from centuries ago and we think it is all new. On a whole, I really enjoyed the piece, it was different and the of the pianist and the string quartets performance were exquisite. The string captured the musical energy and was remarkable to hear and see. When it ended the audience stood and clapped in appreciation for the historical piece performed. Watching this concert was quite magical, from the beginning sounds to the harmonious finale, it invoked a wide range of feelings and emotions and appreciation for the beauty of sound. I had never had the chance to attend a classical concert before this and was pleasantly surprised at how much I enjoyed watching and listening to the pieces presented. If you turn off the stigmata of the words classical music and just listen and enjoy the beauty of the music, I think there are many people who would be surprised at how much they enjoy this music as well. I had a great experience and return with friends next time.
