Abuses of Technology
For the skeptic minds, this quotation is enough to rest the debate, however for many, It becomes important to make them see the other side of the picture as well. Social networking, news and knowledge on the go, cures and diagnosis of many diseases, connectivity around the world and turning the world in to a global village are some of the benefits of the technology. Sadly, humans have become so shallow that we close our eyes to any harmful effect of the things that give us the benefit of even the slightest percentage.Ladies and gentlemen, the problems that we are facing today's are Like a tribe with technology as their tribal flouters ancestor. Allow me to state my stance. Teen depression. Teen suicide. The figures attached to these numbers are massive and the rate of growth In these numbers Is high as well. The mall reason attached behind Is the abuse the teenagers face especially on the social networks such as Faceable. Everyone becomes a victim. No one has a personal life anymore. Privacy becomes an issue. Pictures of girls are circulated around the globe. One rumor is enough to ruin the life of an individual.Family ties are limited online as well. The emotional level is as unpredictable as a network connection. Weapons in the hands of the army are a symbol of valor and safety, in the hands of racist groups are the symbols of terrorism. This is the exact scenario for the social networking platforms. Little good has come out from social media activist than the harm from the rest of the world. Technology is used by many to gain knowledge. Everything is just a click away for the world. But let us question our self on an honest note, what type of knowledge do we gain from it. For how long can we sit and study.Books are the most renewable resource of information and knowledge and even while sitting online, we are referred to books. The harmful causes attached to it, eye sight, and constant vulnerability to radiations lead to cancerous diseases. Let us go back. Ir aq! What good use did technology bring? Nuclear bombs? Weapons of mass destruction? They said technology will lead to the exact location. Let me remind everyone where it led after killings millions, to a single word, Sorry. In the end ladies and gentlemen, I rest my case for the intellect of your mind to decide without being bias.By Sarah Alicia Abuses of Technology By Sarah-Alicia it becomes important to make them see the other side of the picture as well.

Active contours
Active contours Active contours are one category of variational methods that have been used widely within image segmentation applications. An energy functional is defined with arguments as the image parameters and a closed curve that partitions the objects in the image. There are two main methods of representing the curves such as (a) extrinsic and (b) intrinsic. Extrinsic representation keeps function values at boundary points. Intrinsic lets use of functions that are defined on all the point of the image and are more desirable. Intrinsic representation of a planar curve C using an auxiliary function is denoted as C = f(x; y) j (x; y) = 0g (22) where (x; y) is called level set function of curve C and the zero level of (x; y) is taken as the contour. Curvature of the closed curve C with level set function is given by = div( 5 k5k ) (23) The deformation of the contour is reprsented in a numerical form as a partial differential equation @(x;y) @t =j 5(x; y) j ( + ((x; y))) (24) where is a constant speed term to push or pull the contour. Mean curvature of the level set function is defined as: ((x; y)) = xx2 yà ´Ãâ¬Ãâ¬Ãâ¬2xyxy+yy2 x (2 x+2 y)3=2 (25) where x is the first derivative with respect to x and xx is the second derivative with respect to x. The role of the curvature term is to control the regularity of the contour and controls the balance between the regularity and robustness of the contour. Chan Vese formulated the energy function F in terms of an internal force Eint and an external force Eext F(C) = R 1 0 [Eint(C(S)) + Eext(C(S))]ds (26) Eint = length(C) + Area(Cin) (27) Eext = R Cin j I(x; y) à ´Ãâ¬Ãâ¬Ã⬠I1 j2 + R Cout j I(x; y) à ´Ãâ¬Ãâ¬Ã⬠I2 j2 (28) where and are positive fixed parameters which help to smoothen the growing contour. I(x; y) is intensity value of image region and I1 and I2 are average intensity value inside and outside the object region, respectively. IV. IMPLEMENTATION AND ANALYSIS All qualitative and quantitative outcome of the algorithm were recorded by running the Matlab programs with Intel(R) Core (TM) i7 CPU, 3.4 GHz, 4 GB RAM with Matlab 14 (a) on Windows 8. A. Description of Test Data The dataset used in the proposed algorithm consists of scanned images of stained breast biopsy slides from MITOS dataset [35]. Each set is composed of 96 high power field (HPF) images of breast tissue scanned at 40X magnification using two different scanners, Aperio (AP) and Hamamatsu (HM), with a resolution of 0.23-0.24 m:. All the images are 1376 1539 3 size. B. Experimental Strategies This paper qualitatively and quantitatively compares the KHO based optimal nuclei detection performance with the watershed based detection done by S. Ali et al. [8] and blue ratio image based detection done by Irshad et al. [21]. The segmentation performance is compared with local threshold method done by Cheng Lu et al. [22]. 1) Experiment 1: Evaluating the optimal threshold value: Goal of this experiment was to prove the power of KHO based optimal thresholding to detect the exact nuclei regions in histology images. It also compares the optimum value of the threshold obtained by KHO in breast histopathology images with GA, HSA and BFA. 2) Experiment 2: Comparison of Detection Accuracy: Aim of this work is to validate the detection performance of the proposed technique against the watershed and blue ratio techniques in terms of detection sensitivity and precision. 3) Experiment 3: Comparison of Segmentation Accuracy: This evaluates the performance of the detection algorithm in ACM segmentation and compare the results against two state-of-the-art techniques in terms of boundary based distance measures. This experiment also measure the strength of the algorithm to resolve the touching nuclei in terms of touching nuclei resolution.1) Evaluation of Detection Performance: This paper qualitatively and quantitatively evaluates the application of optimal thresholding in nuclei detection performance. The mean objective value and standard deviation express the consistency and stability of the algorithms. The results obtained by KHO are compared with GA, HSA and BFA. The parameters used in these algorithms are given in Table II.The quantitative evaluation of detection performance is carried out by locating the centroid of detected nuclear regions. The measures used to assess the nuclei detection comprise of: 1) Sensitivity (SD); 2) Positive Predictive value or Precision (PD); and 3) F-measure (FD) as given in eq. (26), (27), and (28), respectively. The results obtained are compared with manual detection results by an expert pathologist. The SD and PD values are computed from the number of truepositives (number of correctly detected nuclei, Ntp) , falsepositives (number of wrongly identified nuclei, Nfp) and false negatives(number of nuclei not detected by the algorithm, Nfn). The detected object is considered as true positive if its centroid is within 10 pixels range of manually determined centroid location. If no centroid was manually located within

Titanic Research Paper Example | Topics and Well Written Essays - 1500 words
Titanic - Research Paper Example Broadcast TV shows such as Big Brother, The Simpsons, The View and Family Guy have gained increased popularity over time resulting to unconstructive impacts on the social, political, educational and religious scenes. This essay discusses the negative impacts of Broadcast TV shows by exploring the key areas it touches on. Stereotypes and Prejudices. Broadcast TV shows have been observed to contribute highly in the perpetuation of prejudice and negative stereotypes in the American society (Shaffer 413). Although such shows use this as a form of humor, it has a huge impact on the way society views certain groups of people. Nearly every broadcast TV shows portrays Black males as drug dealers, thugs or criminals. This impacts negatively on the way society view Black males. On the other hand, Muslims are depicted as terrorists which was facilitated by the 9/11 attack. Society is influenced to view them as bad people who are a threat to security. These two examples show how Broadcast TV sho ws promote stereotypes and prejudices in society resulting to tension between racial groups in society. Social Effects. The first social problem arising from watching Broadcast TV shows is lack of originality among the population. People are likely to imitate the TV stars mode of speaking, dressing and personal style which is a common problem among teenagers. Teenagers should strive to seek their own identity and discover their own talents with the help of their parents. This also leads to increased peer pressure as teenagers will strive to dress and act like their friends. Secondly watching TV Broadcast shows leads to the development of anti- social behavior (Clarke 413). This is because individuals tend to spend too much time watching TV and have no time for family, friends or fun activities. Such people tend to be withdrawn and cannot communicate effectively with other members of society. These shows lead to the propagation of negative behavior including violence, crime, premarit al sex and drug abuse. The content aired by these shows has violent scenes that affect the audiencesââ¬â¢ thought in a negative way (Gentile 70). Watching these shows has be a major contributing factor to the rising levels of violence mainly among the young people (Gentile 70). Some scenes have been known to encourage drug and alcohol abuse since they illustrate it to be ââ¬Ëcoolââ¬â¢ and highly appealing to the audience. Some of these shows contain sexual scenes that lead to the high occurrence of teenage sex and pregnancies. This is because such shows depict this behavior to be fun and acceptable. Generally speaking, Broadcast television shows provide the wrong idea about certain practices and make them believe that they are totally fine. Watching these shows is highly addictive hence people do it for many hours in a day. Recent studies have revealed that there is a relationship between the length of time that is spent on watching TV and obesity. Watching TV for long hour ââ¬â¢s leads to a sedentary lifestyle since it is an inactive activity that requires minimal physical and mental activity. People are advised to undertake in physical and mental tasks that stimulate their brain and body to ensure mental and physical fitness. These shows contribute to emotional and physical problems linked to self esteem and weight loss (Shaffer 413). TV stars are represented as having perfect body shapes and flawless skin. Women and young people in society are affected by these images and tend to feel

Comparison contrast essay Example | Topics and Well Written Essays - 1000 words
Comparison contrast - Essay Example The reason for being athletes Athletic can broadly cover all the physical activities that individuals involveinactivities that help boost their physique. People have different motives for participating in sporting events. Allender advocates that frequency of a person in events associated with bodybuildingdetermines the potential to win. An individual requires much physical energy to enhance the capability to perform better. Despite the positive impacts on an individualââ¬â¢s life resulting from involvement in sports, there are differing elements constituting to why individuals continue participating in athletes. Some do it for pleasure while others have hopes of growing into world champions. Contrast between Andy and Darwin a) Strength The strength of an individual player is of prime concern for the ability to remain in the field. Athletes have differing potential due to their frequent partaking in sports. Andy is a tennis player while Darwin is a Cubââ¬â¢s baseball player. Des pite the fact that all are ball games, Mueller states thatessential strength to involve oneself in the game differs from person to person. Andy usesless strength thanDarwin doesdue to the movement one makes when in the field.Opinionatedly, all athletes need enough energy for undertaking their positions while in the field. b) Salary Salary is the primary motive for peopleââ¬â¢s engagement in sporting activities. Through competition, one once declared the champion obtains several medals for the team. The salary attached to various players is different in regard to the activities they carry out. For instance, the salary of Andy is different from Darwinââ¬â¢s salary. The reason for the difference is the incapacitation of the teamââ¬â¢s treasury. Salary difference may also be due to oneââ¬â¢s performance. Coaches are very crucial people in the team, as they are the regulators of activities performed. Coaches are capable of determining who is to do what coaches should ensure t hat all players have equal pay despite what the individual does for the team. Robert, Weinberg, and Daniel illustrate that a better salary system motivates individuals into participating in athletics. c) Human health Physical activities are significant for the health of certain individuals. For one, an individual not fond of sports may end up acquiring some illnesses, some of which are avoidable through chipping in in physical activities. Such diseases as obesity affect the health of an individual and leads to incurring costs for proper medication (Mueller). Andy due to lack of involvement in much movement in the field may develop chronic diseases than Darwin who has to move to the ball. It is worth necessitating individuals have the motive to participate in sports to impede suffering from diseases. Lessons learnt from distinguishing the athletes Through the comparison, it is vital to note that individuals gain important requisites for their bodies. First, it is true that individual s get to know the importance of athletics in their bodies. Allender indicates that athletics help individuals in their health, as it is through exposure to physical activities that one is in a way able to reverse contraction of diseases (specifically, obesity). Secondly, continued involvement in athletic actions keeps the body fit for other activities. One is able to move from a

Question Essay Example | Topics and Well Written Essays - 500 words
Question - Essay Example Intelligence is a personal resource that helps a person to attain personal growth and adjustment into a learning environment. Intelligence is a shield against psychological stress and diseases. Personality on the other hand, is an icon of the intellectual capability of an individual. It affects the person's academic performance by influencing the intellectual functioning of the person. Personality factors determine the results of intelligence test. Personality is responsible for the development of cognitive-adoptive ability that enhances a person's capability to cope with a certain learning environment (American Psychological Association, 1999, p. 30). Personality develops context-bound practical intelligence. This is the kind of intelligence that enables an individual to handle a situational context, and in the case of a learning environment, the learner is able to handle the learning environmental situations, and adapt to the learning environment accordingly. Life span theories have great influence on the teaching strategies that teachers adopt. Life span theories shape the strategies of teaching in that, the instructor must put in mind that, there are general principles that guide development in human beings at different levels of human development (American Psychological Association, 1999, p. 31).

Psy sim 5 - Essay Example In other words, we conform to the behaviors and opinions of others present in the environment. The ambiguity and uncertainty about the nature of the stimuli are the main reasons behind subjects conforming to other people. Ans: The experimental design and the conditions created, that is the experimental and the control groups differed on the method of reporting results. The independent variable used in the study was the social pressure individuals experienced. It was found that the errors given in by the majority of people in the study influenced the perception of the right answer and the subjects gave in to social pressure. Hence they gave wrongs answers. Ans: informational social influence happens when there is no obvious correct answer to quantify the given question or situation. Therefore we look towards others for the information on the issue and in order to be right we get influenced by what they think. This finally leads to internalization. An example can be that in a restaurant we see how people are behaving and we behave in the same way. On the other hand, normative social influence happens when we accept what othersââ¬â¢ perceptions are because we want to be accepted or liked by the group. This influence might also stem from a thought process designed to prevent embarrassment or a possible ridicule from the normative population they belong to. This finally leads to compliance. An example to illustrate is that teenagers start smoking because others in their peer group smoke. Ans: reactance is the desire for personal control. Burger (1987) defined reactance as an emotional reaction in direct contradiction to rules or regulations that threaten or eliminate specific behavioral freedoms. It can cause the individuals to adopt an attitude that is contrary to what others think and increases resistance to social influence. Ans: The thought processes involved the concepts of objects which led the mind to

THINKING HISTORICAL ASSIGNMENT Essay Example | Topics and Well Written Essays - 500 words
THINKING HISTORICAL ASSIGNMENT - Essay Example Moreover, President Wilsonââ¬â¢s decision was primarily motivated by the Germanyââ¬â¢s resumption of submarine attacks on passengers and merchant ships in the year 1917. As a result of subsequent attacks on unarmed passenger ships by the German army, the united states was obliged to set certain terms and conditions that would prohibit this act. This treaty is called Sussex pledge. Violation of this agreement by the German government primarily motivated the United Statesââ¬â¢ entry in World War 1. The military leadership in Germany was however convinced that resumption of unrestricted submarine warfare would enable it to defeat the British within five months, thus they went forward and violated the pledge. However, this decision was conflicted by Theobald von Bethmann-Hollweg. He claimed that violation of the pledge would motivate the American government Participate in the war on behalf of the Allies and he claimed that this would result in the German defeat in the war. Thus the common memory is reinforced since the violation of the pledge resulted in United States entry into the World War 1. The U.S. propaganda with the picture of a lady was meant to motivate women to contributed money that would sustain and give support to the army. It had the following writings on it ââ¬Å"WOMEN OF AMERICA SAVE YOUR COUNTRY Buy WAR SAVINGS STAMPS.â⬠This message was conveyed by the treasury department of United States America. Thus, propaganda uses a technique that appeals for emotion. The propaganda was however been successful since women were not involved in the war directly so they hard to support their countryââ¬â¢s army financially. The technique employed by the propaganda appeals for emotion thus obliging women to support the country. The propaganda was successful due to the fact that the American army received support in varied form, varying from wheat to money while on the war front. War propaganda definitely played a significant role in World War 1 for most
