A Preprocessing Framework for Underwater Image Denoising Essay

Abstract A major obstacle to underwater operations using cameras comes from the light absorption and scattering by the marine environment, which limits the visibility distance up to a few meters in coastal waters. The preprocessing methods concentrate on contrast equalization to deal with nonuniform lighting caused by the back scattering. Some adaptive smoothing methods like anisotropic filtering as a lengthy computation time and the fact that diffusion constants must be manually tuned, wavelet filtering is faster and automatic. An adaptive smoothing method helps to address the remaining sources of noise and can significantly improve edge detection. In the proposed approach, wavelet filtering method is used in which the diffusion constant is tuned automatically. Keywords: underwater image, preprocessing, edge detection, wavelet filtering, denoising. I. INTRODUCTION The underwater images usually suffers from non-uniform lighting, low contrast, blur and diminished colors. A few problems pertaining to underwater images are light absorption and the inherent structure of the sea, and also the effects of colour in underwater images. Reflection of the light varies greatly depending on the structure of the sea. Another main concern is related to the water that bends the light either to make crinkle patterns or to diffuse it. Most importantly, the quality of the water controls and influences the filtering properties of the water such as sprinkle of the dust in water. The reflected amount of light  is partly polarised horizontally and partly enters the water vertically. Light attenuation limits the visibility distance at about twenty meters in clear water and five meters or less in turbid water. Forward scattering generally leads to blur of the image features, backscattering generally limits the contrast of the images. The amount of light is reduced wh en we go deeper, colors drop off depending on their wavelengths. The blue color travels across the longest in the water due to its shortest  wavelength. Current preprocessing methods typically only concentrate on local contrast equalization in order to deal with the nonuniform lighting caused by the back scattering. II. UNDERWATER DEGRADATION A major difficulty to process underwater images comes from light attenuation. Light attenuation limits the visibility distance, at about twenty meters in clear water and five meters or less in turbid water. The light attenuation process is caused by the absorption (which removes light energy) and scattering (which changes the direction of light path). Absorption and scattering effects are due to the water itself and to other components such as dissolved organic matter or small observable floating particles. Dealing with this difficulty, underwater imaging faces to many problems: first the rapid attenuation of light requires attaching a light source to the vehicle providing the necessary lighting. Unfortunately, artificial lights tend to illuminate the scene in a non uniform fashion producing a bright spot in the center of the image and poorly illuminated area surrounding. Then the distance between the camera and the scene usually induced prominent blue or green color (the wavelength corresponding to the red color disappears in only few meters). Then, the floating particles highly variable in kind and concentration, increase absorption and scattering effects: they blur image features (forward scattering), modify colors and produce bright artifacts known as â€Å"marine snow†. At last the non stability of the  underwater vehicle affects once again image  contrast. To test the accuracy of the preprocessing algorithms, three steps are followed. 1) First an original image is converted into grayscale image. 2)  Second salt and pepper noise added to the grayscale image. 3) Third wavelet filtering is applied to denoise the image. Grayscale images are distinct from one-bit bi-tonal black-and-white images, which in the context of computer imaging are images with only the two colors, black, and white. Grayscale images have many shades of gray in between. Grayscale images are also called monochromatic, denoting the presence of only one (mono) color (chrome). Grayscale images are often the result of measuring the intensity of light at each pixel in a single band of the electromagnetic spectrum and in such cases they are monochromatic proper when only a given frequency is captured. Salt and pepper noise is a form of noise typically seen on images. It represents itself as randomly occurring white and black  pixels. An image containing salt-and-pepper noise will have dark pixels in bright regions and bright pixels in dark regions. This type of noise can be caused by analog-to-digital converter errors, bit errors in transmission. Wavelet filtering gives very good results compared to other denoising methods because, unlike other methods, it does not assume that the coefficients are independent. III. A PREPROCESSING ALGORITHM The algorithm proposed corrects each underwater perturbations sequentially.  addressed in the algorithm. However, contrast equalization also corrects the effect of the exponential light attenuation with distance. B. Bilateral Filtering Bilateral filtering smooth the images while preserving edges by means of a nonlinear combination of nearby image values. The idea underlying bilateral filtering is to do in the range of an image what traditional filters do in its domain. Two pixels can close to one another, occupy nearby spatial location (i.e) have nearby values. Closeness refers to vicinity in the domain, similarity to vicinity in the range. Traditional filtering is a domain filtering, and enforces closeness by weighing pixel values with coefficients that fall off with distance. The range filtering, this averages image values with weights that decay with dissimilarity. Range filters are nonlinear because their weights depend on image intensity or color. Computationally, they are no more complex than standard nonseparable  filters. So the combination of both domain and range filtering is known as bilateral filtering. A. Contrast equalization Contrast stretching often called normalization is a simple image enhancement technique that attempts to improve the contrast in an image by ‘stretching’ the range of intensity values. Many well-known techniques are known to help correcting the lighting disparities in underwater images. As the contrast is non uniform, a global color histogram equalization of the image will not suffice and local methods must be considered. Among all the methods they reviewed, Garcia, Nicosevici and Cufi [2] constated the empirical best results of the illuminationreflectance model on underwater images. The low-pass version of the image is typically computed with a Gaussian filter having a large standard deviation. This method is theoretically relevant backscattering, which is responsible for most of the contrast disparities, is indeed a slowly varying spatial function. Backscattering is the predominant noise, hence it is sensible for it to be the first noise Anisotropic filtering Anisotropic filter is used to smoothing the image. Anisotropic filtering allows us to simplify image features to improve image segmentation. This filter smooths the image in homogeneous area but preserves edges and enhance them. It is used to smooth textures and reduce artifacts by deleting small edges amplified by homomorphic filtering. This filter removes or attenuates unwanted artifacts and  remaining noise. The anisotropic diffusion algorithm is used to reduce noise and prepare the segmentation step. It allows to smooth image in homogeneous areas but it preserves and even enhances the edges in the image. Here the algorithm follow which is proposed by Perona and Malik [5]. This algorithm is automatic so it uses constant parameters selected manually. The previous step of wavelet filtering is very important to obtain good results with anisotropic filtering. It is the association of wavelet filtering and anisotropic filtering which gives such results. Anisotropic algorithm is  usually used as long as result is not satisfactory. In our case few times only loop set to constant value, to preserve a short computation time. For this denoising filter choose a nearly symmetric orthogonal wavelet bases with a bivariate shrinkage exploiting interscale dependency. Wavelet filtering gives very good results compared to other denoising methods because, unlike other methods, it does not assume that the coefficients are independent. Indeed wavelet coefficients in natural image have significant dependencies. Moreover the computation time is very short. IV. EXPERIMENTAL SETUP AND EVALUATION To estimate the quality of reconstructed image, Mean Squared Error and Peak Signal to Noise Ratio are calculated for the original and the reconstructed images. Performance of different filters are tested by calculating the PSNR and MSE values. The size of the images taken is 256Ãâ€"256 pixels. The Mean Square Error (MSE) and the Peak Signal to Noise Ratio (PSNR) are the two error metrics used to compare image compression quality. The MSE represents the cumulative squared error between the compressed and the original image, whereas PSNR represents a measure of the peak error. The lower the value of MSE, the lower the error. In Table 1, the original and reconstructed images are shown. In table 2, PSNR and MSE values are calculated for all underwater images. PSNR value obtained for denoised images is higher, when compare with salt and pepper noise added images. MSE value obtained for the denoised images has lower the error when compared with salt and pepper noise added images. e D. Wavelet filtering Thresholding is a simple non-linear technique, which operates on one wavelet coefficient at a time. In its most basic form, each coefficient is thresholded by comparing against threshold, if the coefficient is smaller than threshold, set to zero; otherwise it is kept or modified. Replacing the small noisy coefficients by zero and inverse wavelet transform on the result may lead to reconstruction with the essential signal characteristics and with the less noise. A simple denoising algorithm that uses the wavelet transform consist of the following three steps, (1) calculate the wavelet  transform of the noisy image (2) Modify the noisy detail wavelet coefficients according to some rule (3) compute the inverse transform using the modified coefficients. Multiresolution decompositions have shown significant advantages in image denoising. best denoised image. In clearly, the comparisons of PSNR and MSE values are shown in Fig -1a and Fig -1b. V. CONCLUSION In this paper a novel underwater preprocessing algorithm is present. This algorithm is automatic, requires no  parameter adjustment and no a priori knowledge of the acquisition conditions. This is because functions evaluate their parameters or use pre-adjusted defaults values. This algorithm is fast. Many adjustments can still be done to improve the whole pre-processing algorithms. Inverse filtering gives good results but generally requires a priori knowledge on the environment. Filtering used in this paper needs no parameters adjustment so it can be used systematically on underwater images before every pre-processing algorithms. REFERENCES [1] Arnold-Bos, J. P.

Psychology Perspectives: Columbine Massacre

Perspectives of Psychology: Understanding the Columbine Massacre In Psychology, there are perspectives and approaches that are looked into when trying to understand how the intricate human mind works. These perspectives are respectfully derived from different ideas and time periods, exemplifying different ways of thinking. These perspectives include: sociocultural, biopsychological, psychodynamic, behaviorism, cognitive, and humanism. These approaches are critically essential in solving something as serious as murder, or simply even why someone acts the way they do.There are many instances where there will be shocking news stories about people committing murders—people that are so unexpected to do such harm. However, when the six perspectives are properly enforced, we can infer and comprehend the situation and reasoning. These handy tactics and knowledge help us understand the underlying core reasons for even the most bizarre and deadliest cases such as the Columbine High Scho ol Massacre. This massacre is the world’s deadliest high school shooting that was embarked by two senior students, Eric Harris and Dylan Klebold.The pair initially intended to kill thousands of students, however the bomb did not go off as planned. Unfortunately, the malicious killers managed to kill twelve students, one teacher, and greatly injured 21 helpless students. Not only did they engage in such acts, but once they were satisfied with their spree, they committed suicide. This tragic event was greatly televised as it forced schools around the country to enforce strict laws of security.The unbelievable acts of Eric and Dylan left everyone with many questions as to why these seemingly normal students would take the lives of so many, and also themselves. However, we begin to understand how deceiving looks can be as we deeply examine past the superficial surface of these two killers. A modern perspective in psychology is the sociocultural perspective, which accordingly comb ines two fields of study: social psychology, which is the study of social roles, actions, relationships; and cultural psychology, which is the study of cultural norms, values, and expectations.These are closely tied due to the fact that they are both about the effect that people have on one another, either individually or in a larger group as a broad culture (Peplau&Taylor, 1997). In short, First of all, sociocultural is a modern approach where culture, race, genders, and backgrounds are studied closely to better understand behavior. This sociocultural perspective is evident in this case, because according to psychologists, Kimmel and Mahler, the two shooters were white males who did not project the male gender roles other students possessed.According to USA Today, the shooters, Harris and Klebold, were seen as outcasts due to their unusual behavior and inability to conform to society. Harris and Klebold allegedly created a website on how to commit crimes varying from theft to somet hing as dangerous as bomb explosions. Both Kleboid and Harris were victims of bullying. I am driven to believe their unacceptance to society and perhaps their culture, enticed them to go on a killing spree. Also, I believe the violent messages sent by heavy metal music, violent televised movies and shows, and other subcultures also served as a factor for the massacre.More often than not, psychologists ponder on whether chemical imbalances can really affect the way a person acts and thinks, and how it can affect their lifestyle. This perspective is known as the biopsychological perspective. This perspective is also fairly modern, as it focuses on influences of hormones, brain sructures and chemicals, and diesaease. This being said, this approach is strictly thought that human and animal behavior is seen as a result from events going on inside the body (Ciccarelli, 2012). According to journalist, Dave Cullen of the New York Times, Dylan Kleboid was diagnosed with depression.The biolog ical approach can be well implied in this situation because as stated earlier, his chemical imbalances acted as a hindrance in his life, creating more reason and desire to kill others, and also kill himself. The next theory is categorized as a less-modern perspective as it goes all the way back to the Victorian Era. This approach is based on Sigmund Freud’s theory of psychodynamic, which focuses on the role of the unconscious mind and its influence on conscious behavior, early childhood experiences, development of sense of self, and other motivations. Ciccarelli, 2012). In other words, this theory states that humans have an unconscious mind in which we repress all of our threatening urges and desires into. In effect of repressing urges, it creates nervous disorders. This approach greatly stresses the importance of early childhood experiences. I firmly believe that both boys, especially Klebold, repressed their urges and thoughts which created a dramatic lash-out. According to New York Times, Klebold had come from a very well educated family that had very high expectations for him.His childhood had been constricted to studying and since he was exposed to such lifestyle at such a young age, he grew accustomed to better his education. Kleboid showed no obvious signs of danger to his family, as he valued how he appeared to his parents. However though, he had a great drinking problem which caused major aggression. Harris, Klebold’s good friend, was greatly interested in creating bombs. His childhood was not like Klebold’s—his family was not as forceful of his studies, or close. Harris was diagnosed with depression—leading him to have suicidal thoughts.According to At the time of his death, he had unbelievable Luvox levels in his system. According to psychiatrist, Peter Breggin, these medications very likely have contributed to Harris's actions. Harris had been meticulously planning bombings but did not have the means of creating o ne. That is where his good friend and brains of the pair, Klebold, comes into play. The two boys’ lives are well exemplified and reinforced by the psychodynamic approach, as their childhood seemed to shape their lives as they grew older. The next approach is the behavioral perspective.This perspective is based on the early work of Watson and Skinner. Behaviorism concludes that the science of behavior must be directly seen and observed to be validated. This being said, we must ignore â€Å"consciousness† and focus on observable behavior. This approach is shown by the pair because both boys had been convicted of breaking into a van and stealing computers. According to Wikipedia. org, after breaking into the van, Harris blogged: â€Å"Why shouldn't we, the gods, have the right to break into a van that some mother***** left in the middle of nowhere?! This clearly shows the behavior of the boys that can be observed, not inferred. This behavior is very violent, and it is cl ear that the boys show no remorse or guilt for their wrong-doings. Another less modern approach would be the cognitive approach. This approach focuses on memory, intelligence, perception, thought processes, problem solving, language, and learning (Cicarelli, 2012). This perspective can be applied to Harris and Kleboid’s sitatuation by looking into their background and how that affects their thought processes and learning skills.As mentioned earlier, Kleboid was clearly bright. He was capable of creating bombs (although the bombings were unsuccessful) and devising a master plan. He carefully planned out the steps of what was happening. How can we be so sure? According to Time Magazine, Kleboid and Harris had been writing their step by step ways of creating a bomb. Not only so, but they clearly showed intent of killing thousands of students. I believe that this shows the boys had planned out a meticulous plan, also acknowledging the consequences, therefore decided to kill thems elves at the very end.At last, we have the Humanistic approach. This approach focuses on human potential, free will, and responsibility. This approach is sought to highlight human values and self-actualization. Humanism proposes that the deeds we do in life are not driven by childhood experiences, influences, cultural background, genetics, or chemical imbalances; but rather, it is driven by our will to be defined as a good or bad person. This perspective focuses on our underlying core values solely as individuals. This perspective can best be shown through the level of intellect the boys have.According to The Guardian, the boys have shown academic proficiency for a good part of their high school career. They were gifted in computer work, and were in charge of technical duties for school plays. With this being said, I believe the boys understood that their behavior is solely determined by their own will to be the type of person they aspire to be. Needless to say, I believe the boys w ere greatly influenced by their cultural background and society, but however, I also strongly believe Kleboid and Harris were intelligent enough to make their own decisions—engaging in good or bad behavior, reflecting their human values.Psychology is a very broad subject filled with endless questions and theories. These perspectives, however, are greatly established and used on a day-by-day basis by not only psychologists, but investigators and sociologists as well. These perspectives help to understand and widen our knowledge of humans and animals. The six perspectives are all derived from different time periods—varying from modern to not-so-modern theories and ideas. The perspectives help address problems and help widen critical thinking abilities, as well as understanding everyday behavior.

The Relation of Heat to Kinetic Theory of Matter Essay

The Relation of Heat to Kinetic Theory of Matter - Essay Example It means that movement of molecules or atoms becomes more when there is more heat. Molecules or atoms have energy preserved in them. They have potential energy as well as kinetic energy and these energies together form thermal energy. Thermal energy moves from an object having high temperature to an object having low temperature and with this movement (Maxwell, 1871), the movement of molecules or atoms also gets faster. The object having high temperature will have fast moving molecules or atoms. Therefore, it is quite clear that the study of heat is related to the kinetic theory of matter. 2. What is temperature? Heat is a process in which, thermal energy shifts from an object of high temperature to an object of low temperature. Heat is not pre-located in matter. It is created and can be noticed as shifting of thermal energy between objects based on temperature difference between the objects. There can be many examples of heat. When we touch a hot surface, the thermal energy shifts f rom the hot surface to our hand due to which, we feel heat as there is a temperature difference between the hot surface and our hand, which on touching shifts. In this way, we can say that the temperature is the measure of heat energy. With the help of a temperature scale we can estimate the degree of hotness or coldness of the surrounding atmosphere or any object. 3. What is the relationship between heat and temperature? While heat is a form of energy that can be converted to any other form, temperature is only an effect caused by the heat. However, both the quantities heat and temperature are directly proportional to each other. If one quantity rises the other also varies directly, if one lowers the other quantity lowers too. The more the amount of heat the more will be kinetic energy of molecules while temperature is the measure of the degree of motion of particles in a system. 4. What are the various properties of a substance that determine its heat capacity? The most important factor that determines the heat capacity of a substance is the energy state of the molecules of the substance that is the direct measure of the heat capacity of a substance. The difference of the heat capacities of the two substances is due to the difference in the molecular energy state of the two substances (Hagg, 2011). The other factors that determine the heat capacity of the material are the pressure, composition of the substance and the temperature. Pressure makes the molecules to be close to each other that make the molecules to collide in a more repetitively that increase the average kinetic energy of the molecules and changes the energy state of the material. Under pressure the three state of the matter behave differently (Belzer, 2011). Gasses are most influences by the pressure and temperature while solids gave little impact when they are under pressure as the molecules are close enough in the solids. As the temperature of the substance is raised the bond between the mole cules weakens and the matter changes its state, as solids when heated to a certain temperature melts to a liquid form and liquids change to gaseous form when heated to a certain temperature. Composition of the material can change its heat capacity by altering the energy states of the material. 5. What are the var

Evolution of Human Parental Care and Recruitment of Juvenile Help Research Paper

Evolution of Human Parental Care and Recruitment of Juvenile Help - Research Paper Example Cooperation between parents and juveniles The costs incurred in the raising of a child are high, and this is the reason parents opt for smaller families. The costs involved in this process tend to be high due to the investment in them and that they are free from any work. The cost of raising children in the pre industrial age was not as high since the children gave back to the society (Karen 54). Children receive assistance from their parents, and as so, their parents benefit from the assistance of their own children. The juvenility as such has a twofold nature of receiving and giving back. Juveniles both depend on their parents and at the same time help the parents. Young juveniles provide valuable childcare assistance to their siblings in many societies. The dependence and help from juveniles are some features that determine the modern human beings. Even, though, juveniles receive a lot of assistance from others, they also give back to by exchanging labor and resources with others more so those who assist them. Enlisting of juvenile help by the restructuring of parental investment to involve juveniles gives the humans an advantage (Royal society (Great Britain) 156). They are associated advantage to be able to both increase reproduction and increased offspring survival by incorporating interdependence at various ages. In the quantity-quality, trade off the determination of the quality of an offspring stems from the parental care given. The quantity or quality of resources allocated by the parent to the offspring is dependent on the ability of the parent to harness energy from the environment. The quantity-quality theory argues that if there are extra parental inputs these can affect the quantity or quality of the offspring by either direct allocation to the offspring quality and include food provision, childcare, all nursing, financial or other transfers. Extra parental inputs can also decrease the energy that the mother employs in providing and other activit ies leaving a metabolic stability for lactation and reproduction. Notwithstanding the physiological constraints in offspring production, quality of offspring is not necessarily a purpose of quantity. A juvenile who is not sexually mature to fit into the production class and not competing for mates does not fore go many costs. If the juvenile contributes in any way, directly or indirectly, and results in the reduction of the mothers energy employed the juvenile receives immediate fitness benefit and does not have to wait to maturity in order to benefit. According to Karen (88) division of labor celebrated as an age association as efficiency improves when inequities in return rates differ between tasks and individuals. When there is an adjustment of the level of investment by parents based on the availability of helpers, where help is sensitive to help accorded by juveniles then there can arise some changes. When the parents get helpers, they may increase their levels of investment an d retain the same level of care to the offspring’s and transferring the saved energy to the task of reproduction. The number of children might increase without necessarily reducing the survivorship or child quality unless the number of the helpers also decreases. If, on the other hand, the number of helpers increases due to the recruitment of juveniles, the parents then placed in a position to produce more children

Examining Representation Of Suburbs And Model Dwelling Essay

Examining Representation Of Suburbs And Model Dwelling - Essay Example The house is well fenced with a stone field. The painting shows that Pissarro had visited Bedford Park during the summer in 1987. First, mansion displayed on the other side of Lucien’s house is a modern building with special features. For instance, the entire building is made up of three buildings that are joined together. This design reveals that there is technological development in structural designs of model dwellings or mansions. Secondly, mansions or model dwellings in London are well connected by good transport systems like roads. Pissarro's painting "Bed road" displays the presence of a well-developed road passing between model dwellings. The colorful painting of the mansions in the "Bed road" displays the high quality of the building and the wise selection of colors by ancient house designers. In comparison to the recent picture of the Bed road, Bedford Park in 1995, there are similarities in the house design and the colorful painting on the walls. These similarities depict that Pissarro's ideas on his work would come true in the future. In conclusion, the two paintings discussed above reveal that the 19th century and 20th-century artists had unique skills and capabilities of representing different structures in different places using oil paintings. In his two paintings, Camille Pissarro was able to display the ancient structures developed using high technology. Structures like model dwelling in were characterized by colorful paintings and good transport system as displayed by Pissarro's paintwork.

What you learned in speech course Essay Example | Topics and Well Written Essays - 750 words

What you learned in speech course - Essay Example Previously I was very shy about talking out in public and standing up in front of a crowd. However, this speech course has helped me tremendously in boosting up my confidence level. Now not only am I able to present myself much more properly but I believe I am even more calm and composed as I deliver speeches. Before all this started I recall how much I used to shiver with the mere thought of getting on the stage to deliver a speech. But as I moved on with this course I discovered that having speaking related anxiety is as completely natural as anything else. I discovered that I was not the only person in the room who felt he couldn’t deliver, and there were a lot of other similar souls. There is a lot that I have learned from this speech course and time would run out if I start mentioning everything here. I believe this course has helped me a great deal in overcoming my fears to start off with. I always thought presenting to a crowd is a great deal and not everyone’s c apable of it. However, the day I stepped onto the podium my thinking changed and I left all my fears behind. It must be mentioned here that my instructor helped me a great deal with my speech and pointed out mistakes where I was wrong. This course, I believe has taught me to look inside my self and share my feelings with the audience. I learned that while delivering a speech you have to adjust your tone and message according to the audience’s feedback. I remember how I was rushing through my speech on automotive engines until I looked into the eyes of a couple of students in the audience. Their eyes zoomed me in like I was saying something alien to them. It was then that I realized that there’s something wrong with my presentation and adjusted I slowed down. This speech course this helped me figure out that speech delivery is all about adjustment to your audience’s feedback. It taught me you have to step into your audience’s shoes and figure out if you wo uld have understood the same had you been in their place. This speech course has also helped me a great deal in being able to speak clearly yet concisely and confidently. It made me realize the importance of proper speech delivery and the impact it can make on the life millions of people around you. I realized that developing upon your speech is not only essential in getting a good grade in this course but it helps you a lot in speaking out in tons of other important situations as well. I also learned that proper speech and presentations do not only help us to present ourselves effectively in front of others but help us get control of and master our lives. I also realized that it is our speech that makes us unique from thousands of people around the world. They say everyone’s equal and that fact is true but having command over proper speech is what distinguishes a learned person from an ill literate one and makes you stand out in front of a crowd. I would like to sum it all u p by saying this speech course has ideally changed the course of my life and how I used to see things. Now I believe if you can communicate properly and make yourself heard then you can overcome any obstacle in

Project Finance (Project Management) Essay Example | Topics and Well Written Essays - 1000 words - 1

Project Finance (Project Management) - Essay Example â€Å"Project finance is the financing of long-term infrastructure, industrial projects and public services based upon a non-recourse or limited recourse financial structure where project debt and equity used to finance the project are paid back from the cashflow generated by the project† (Project Finance Definition). Simply speaking, project finance is the process of accumulation of money and its investment in some particular project. Usually, there are two types of project finance – equity financing and debt financing. The debts and an interest rate are paid from the cash flows, generated by a project. Generally, project finance can be called as a part of project management. Project finance is usually a long-term process. The reason for it is that the projects financed are long-term as a rule. This process begins from looking for the ways of a project’s financing and ends with paying dividends to stakeholders and investors. . â€Å"It takes a lot more than a good idea to develop a successful manufacturing venture. You need to know where to find the resources, both financial and technological, and you need to find the right people with the right skills to do the job. Knowing where to look for these resources can save you precious time and money, and earn you some valuable partners in the process† (Sudarkasa). Identification and development of a project – any project should be presented to potential investors in some formal way. They should be able to weigh up all the pros and cons for a project. This information is needed to make a final decision whether to invest or not in a project; Determination the feasibility of the project – the main factor for investors is whether a project is able to bring social and economic benefits or not. That is why a vivid plan how to earn money should be drawn and presented to all the stakeholders. These two stages are among the most important in the process of

Iran and Iraeli Current Situation Research Paper

Iran and Iraeli Current Situation - Research Paper Example Iranian Nuclear Program - Historical Background Being launched in the 1970s under the Shah, the series of Iran’s ambitious nuclear projects heavily relied on the U.S. and European assistance – Iran had struck a deal with the West-German company, KWU, to build two 1Â  200 megawatt reactors and negotiated the construction of another two 900 megawatt reactors with the French ‘Framatome’ (Iran Watch, 2012). The goal set by the Shah had been for the country to produce over 20Â  000 megawatts of electricity from nuclear power stations within the next twenty years (Iran Watch, 2012). Following the revolution in 1979 and the war with Iraq that started in 1980, the nuclear energy program had been abandoned and the existing infrastructure – considerably damaged. However, since the late 1980s, Iran’s nuclear program had been revived and given a fresh impetus via the assistance from Russia and China (Iran Watch, 2012). ... Q. Khan (Iran Watch, 2012; Cronin, Kronstadt and Squassoni, 2005). Both actual progress and probable scope of Iran’s nuclear program became clear, to a degree or another, in 2003, when the International Atomic Energy Agency (IAEA) conducted a series of safeguards inspections, along with verification of Iran’s activities in the area of uranium enrichment, intended to set off implementation of the NPT Safeguards Agreement in the country (IAEA, 2003). Having found no evidence of activities related to development of nuclear weapons by then, the Agency emphasized the necessity of further inspections, enough time and Iran’s full cooperation, in order to be able to conclude that Iran’ nuclear program is exclusively for peaceful purposes (IAEA, 2003). In 2004, however, Iran was rebuked for failing to cooperate with IAEA’s inquiry and agreed to suspend most of its uranium enrichment activity under a deal with the EU; nevertheless, uranium conversion was resu med at Isfahan plant in 2005, and Iran was accused of violation of NPT (Aljazeera, 2012). From 2005 to 2009, there were a series of breaches in Iran’s promises and the agreements with IAEA concerning the uranium enrichment activities, accompanied by sweeping U.S sanctions against the country, Iran’s rocket-test launches, including such of a of a long-range missile capable of reaching Israel, and a UN Security Council resolution on Iran’s uranium enrichment program (Aljazeera, 2012). Following the new disclosure of an underground enrichment facility at Fordow, nearby Qom, and Iran’s rejection of the international demand for freezing the project, several important developments took place in 2009, including an IAEA report that suggested for the first time Iran might be chasing

Scarcity and Compassion Essay Example for Free

Scarcity and Compassion Essay According to the Oxford dictionary, scarcity is the same as shortage or presence in small numbers. In economics, scarcity is defined as the condition whereby human wants and needs exceed what is produced or what can be produced by the available resources (Harford, 2006). On the other hand, compassion is the belief in fairness in distribution of resources our humane aspects should not allow us to see others live without resources while we are capacitated to provide to them. Economists have pointed out over the disagreement between these two aspects as one calling for equitable distribution of resources to all persons while the other points out equal distribution of resources is impossible as there are no enough resources for everyone. Scarcity thus explains the presence of the rich and the poor. Compassion plays a big role as evidenced by empirical evidence on the ground especially on international level. Wealthy nations have always made attempts to make some of their resources available to poor nations (Harford, 2006). Note that, the resources given away as aid are not excess/ surplus resources per se. They are obtained from the taxpayer’s money whereby taxpayers could have allocated such resources in more economically viable options. Therefore, compassion by nations and/or on a household level continues to play great role in distribution of scarce resources. The fact that man is a social animal ties him to the idea of sharing his economic resources with the ones deprived of those resources. The knowledge by an individual of the suffering of another due to lack of resources either acting on a household level or any economic unit drives that individual to make decisions and/or implement policies that will favor the underprivileged according to his view. This explains why there are tax cuts and social benefits to the low income earners and unemployed respectively. Thus compassion plays and continues to play a significant role in the distribution of scarce resources.

Streptozotocin (STZ) Induced Diabetes Experiment

Streptozotocin (STZ) Induced Diabetes Experiment MATERIALS AND METHODS 3. MATERIALS AND METHODS 3.1 Animal Selection and Care STZ induced diabetes are commonly performed in Male Wistar Kyoto rats. In these models, male Wistar rats at 8 weeks of age (200–300 g) are selected from animal supply facility of SGPGIMS Lucknow, and house in a 12-h light, 12-h dark cycle environment, temperature 25 °C, with standard rat diet and water in metabolic cages for one week prior to STZ treatments. The study had clearance from Institute animal ethics committee. 3.2 Study Design Wistar Rat (Preparation and Validation of animal model of DN) 50 mg/kg STZ induced Diabetic Rat (n=3) Normal Rat (n=3) After 8th week rat are sacrificed for validation of Diabetic nephropathy 3.3 Induction and Validation of Diabetes by Streptozotocin There is a lack of appropriate animal model that could spontaneously develop DN. It has been a significant limitation to find out specific factors that is underlying this disease and also the development of new therapeutic methods or strategies to prevent progressive renal disease in diabetes (Morcelo A. Nobrega et. al. 2004). Most Sprague-Dawley (SD), Wistar-Kyoto (WKY) rats are used as model for performing STZ-induced diabetic nephropathy. Here, in these models, 8 weeks old male rats (200-250gm) are starved or kept on fasting for 18hrs and after that STZ was injected intraperitoneal (WKY-50mg/kg, SD-55mg/kg and SHR-45mg/kg) with sodium citrate buffer (1ml/kg) (Ma G et. al. 2004 and Cooper ME et. al. 1988). STZ given here intraperitoneally to the rats, however, it is a very less common procedure as intravenous injections are comparatively easy to perform in rats and give more reliable results. In addition to the STZ dosage required for inducing diabetes via an intraperitoneal route is relatively higher as compared to other route. After giving STZ, the rats should be given ample amount of drinking water with sucrose for 48 hrs (15g/L), to avoid early mortality of rats as stored insulin is released from damaged pancreatic Islets of Langerhans. After completion of 1 week of STZ induction, the rats must be assessed for hyperglycaemia and also those with fasting blood glucose of over 280 mg/dl (15 mmol/L), which is usually around 90%, and it should be included in the studies of diabetic nephropathy. In order to prevent subsequent development of ketone uria, subsequent injections of long-acting insulin (approx. 2-4 U/rat) should be given daily to maintain the blood glucose levels in a desirable range(300-600 mg/dl, 16-33 mmol/l) (Davis BJ et. al. 2003). Studies exploring the effects of treatment on the development of DN should not be underway until at least 3 weeks after STZ when the kidneys have improved from the acute mild nephrotoxic effects of STZ (Kraynak AR et . al. 1995) This drug i.e., STZ has been shown to induce a diabetic state in 72 hrs (3 days) as documented by examining tail blood samples using a Glucometer (Optimum Exceed) Diabetic animals and non-diabetic control group were kept in metabolic cages individually and separately and under feeding and metabolism control. Glucose in the blood of diabetic rats exceeded that of the non-diabetic control ones. Food consumption was measured in terms of (gm), water consumption was measured in terms of (ml) and urine volume was measured in terms of (ml) on a daily basis and glucose in blood serum were also measured, so that chemical diabetes was verified in rats injected with Streptozotocin. 3.4 Estimation of Creatinine Modified Jaffe’s method was used for colorimetric estimation of creatinine concentration in urine samples. Principle: Creatinine + picric acid Creatinine picrate (Yellow) (Orange) The resultant orange color is measured colorimetrically. However, the intensity of the resultant orange color is directly proportional to the concentration of creatinine in the sample. Method: Draw the Blood from a vein and then transferred into the vial. Centrifuge the blood for 10 minutes and Serum is obtained. Separate out the serum in different eppendrofs. The concentration of creatinine is calculated in the serum sample using the Jaffe’s method, as follows: In a clean dry test tube add 0.5 ml distilled water (blank) or serum (test), add 0.5 ml NaOH and then 0.5 ml picric acid. Mix all the contents of each tube. Left to stand for 15 minutes. The absorbance is measured at ÃŽ »max 500 nm. If a standard creatinine solution (0.55 mg/dl) has an absorbance value of 0.30, then the concentration of creatinine in the provided serum sample is calculated by using the following equation: Ctest = Cstd x 3.5 Estimation of Urinary Albumin Enzyme linked immunosorbent assay (ELISA) for detection of rat albumin in serum, plasma or urine. Other biological fluids that contain Rat Albumin, such as faeces or saliva, may be suitable samples. 3.5.1 Principle: The antigen present in urine sample are allowed to stick to a poly vinyl and then plate is washed to separate antigen and antibodies from remaining sample components. To this plate a corresponding second antibody is added to get fixed to the already adhered first antigen in the plate. To this added second antibody, an enzyme is also tagged is that, when a suitable substrate is added, the enzyme reacts with it to produce a colour. This colour produced is measurable as a function or quantity of antigen present in the urine sample and there by identified. 3.5.2 Chemical and material required: 96-well plate ELISA Coating Buffer ELISA Wash Solution ELISA Blocking Buffer Sample/Conjugate Diluent (ELISA Blocking Buffer + Tween 20) 10% Tween 20 Enzyme Substrate, TMB ELISA Stop Solution Additional Materials Required: Ultrapure water Precision pipettors, with disposable plastic tips Polypropylene, polyethylene or glass tubes to prepare standard and samples Containers to prepare buffers An aspiration device or an automated 96-well plate washer Disposable reagent reservoirs A standard microtiter plate reader for measuring absorbance at 450 nm 3.5.3 Procedure: Added 100  µl of diluted coating antibody to each well. Samples were run in duplicate. Incubated at room temperature (20-25 C) for 1 hour. Washed plate FIVE times. Added 200  µl of Blocking Solution to each well. Incubated at room temperature for 30 minutes. Washed plate FIVE times. Added 100  µl of standard or sample to well. Incubated at room temperature for 1 hour. Washed plate FIVE times. Added 100  µl of diluted HRP detection antibody to each well. Incubated at room temperature for 1 hour. Washed plate FIVE times. Added 100  µl of TMB Substrate Solution to each well. Developed the plate in the dark at room temperature for 15 minutes. Reaction was stopped by adding 100  µl of Stop Solution to each well. Absorbance was measured on a plate reader at 450 nm. 3.5.4 Precautions: Store all reagents at 2-8 ºC. Do not freeze reagents. All reagents must be at room temperature (20-25  ºC) before use. Vigorous plate washing is essential. Use new disposable pipette tips for each transfer to avoid cross-contamination. Minimize lag time between wash steps to ensure the plate does not become Completely dry during the assay. Avoid microbial contamination of reagents and equipment. Automated plate Washers can easily become contaminated thereby causing assay variability. Take care not to contaminate the TMB Solution. Do not expose TMB Substrate solution to glass, foils, or metal. If the solution is blue before use, do not use it 3.6 Oral Glucose Tolerance Test Rats are fasted overnight (12-16 hours) before the test, sedated rats, will be given 50 % dextrose (3ml/kg body weight) intraperitoneally. Whole blood will be collected from the tail vein at 0, 15, 30, 60, 120, and 180 min after the administered of glucose for the measurement of glucose with a glucometer. 3.6.1 Material Required: Glucometer and glucose strips Dextrose Gauge needles Timer and Pen Table of mice for record keeping of glucose values 3.6.2 Preparations before the test: Weigh the animals before the test. The animals are fasted overnight (approximately 16 hours: 5 pm to 9 am). Place each of the animals in a separate fresh cage with no food, but make sure they have water bottles. Make sure that there is no activity in the animal room before and while you are performing the test. Prepare the glucose solution the night before the test. 3.6.3 Procedure: After the overnight fast, blood glucose was determined (time 0) in a drop of blood as following: Rats were placed on top of the cage (let it hold onto the grid). The tail tip was pricked with a needle, wiped off the tail tip with gauze, and the next drop of blood was used for the determination of glucose with a glucometer. Glucose solution was given orally. Blood glucose was determined at 10, 20, 30, 60, 90 and 120 min after the administration of glucose. For the determination of glucose at each of these time points collected a drop of blood as following: wiped the cut end of the tail to break any blood clot that had formed and collected the next drop of blood. If the blood does not appear spontaneously â€Å"milk† the tail by holding the tail between your thumb and index finger and move along the tail from the base of the tail to the tip of the tail while applying gentle pressure. 3.7 Assessment of Renal Histopathological Injury 3.7.1 Tissue preparation for histology: After 8 weeks the rats were weighed, sacrificed out in accordance to the Institutional animal ethics committee by using suitable anaesthetic agent (Ketamine) and their kidneys were taken out. Left kidneys were perfusion fixed for Histopathological and IHC studies and right kidneys were freezed immediately for western blotting and RT-PCR. Preparation of paraffin blocks of kidney: Kidneys were preserved in Para- formaldehyde is taken out in a glass slab for sectioning. A two cross section of upper half of kidney was done with sterile blade for paraffin embedding. The whole process for preparation of paraffin blocks took two days. Day first: The Formalin fixed kidneys were picked up and place in plastic cassettes was sequentially dipped in alcohol for dehydration. The schedule is as followed: 50% Alcohol →1.5hrs 70%Alcohol →1 hrs. 80% Alcohol →1 hrs. 90% Alcohol →1hrs 100% Alcohol →1hrs (twice) The cassette containing the tissue was left overnight in 100% absolute alcohol. Day Second: On 2nd day we perform the following treatment to tissue containing cassette Cassette was removed from 100% alcohol and dipped for CHCl3 treatments Chloroform (A) 1.5 hours. Chloroform (B) 1.5 hours. Chloroform (C) 1.5 hours. The cassette was then kept in melted paraffin wax (at 58 °C 65 °C in water bath) following two changes of paraffin wax for proper blocking. The steel chocks are kept at the 65 °C electronic heater and the paraffin treated kidney in plastic cassettes are opened and place in pre-heated steel chocks together with melted paraffin wax and closed with cassette. Block was kept at room temperature to solidify the melted wax. The paraffin block containing tissue was sectioned with microtome. The block was fit properly in the Microtome machine 5 µ sections were cut. 3.8 Periodic Schiff’s Acid (PAS) Staining 3.8.1 Principle: PAS (Periodic Acid Schiff) is a method of staining used for the detection of polysaccharides i.e., glycogen and mucosubstances that is glycoprotein’s and glycolipids. PAS stain is a histochemical reaction. In the reaction, periodic acid oxidises vicinal diols in these sugar. It oxidized the aldehyde formed by carbon-carbon bonding that react with fuchsin-sulphurous acid and forms the magenta colour. This periodic acid exposes the glycogen to give a colouring product. The Schiff’s reagent is a very specific agent that only reacts with the carboxylic group compounds. Material required: Glass slides and cover slips Poly Lysine (Sigma Aldrich, USA) Xylene Graduated Alcohol (30%, 50%, 70%, 90% and 100%) Periodic acid Schiff Reagent Haematoxylin Acid alcohol (1% HCl in 70% alcohol) DPX mountant 3.8.3 Protocol for PAS Staining: Keep the Poly-Lysine coated slides on hot plate for 15-20 min. Dip in warm Xylene for 10 min twice. Pass the slide through graded alcohol 100% alcohol- (10 minutes) twice 90% alcohol (5 minutes) 70% alcohol (5 minutes) 50% alcohol (5 minutes) 30% alcohol (5 minutes) Dip in distilled water for 5 min. Place the slide containing section into 0.5 % Periodic acid for 5 minutes. Rinse with distilled water. Schiff Reagent was added for 10 min until deep magenta colour appear. Wash in running tap water for 5 min. Counter stain in haematoxylin Rinse with distilled water. If high stain come, then wash with acid alcohol (1% HCl+70% alcohol) Wash the slide in tap water. Dehydrate in alcohol, and dry the slides. After drying mount the slides by DPX mountant. Masson’s Trichrome Staining 3.9.1 Principle: MT Staining method is used to demonstrate the increase of collagen in diseases. This method of staining uses three dyes of contrasting colours for the selective staining of basic tissue components i.e., muscle, collagen fibers, fibrin, and erythrocytes. The general phenomenon of trichome staining is that smallest dye molecule colours or stains the less porous tissues. However, the penetration of dye of larger molecular size is depends on the expense of small molecules. Some others suggests that the acid dye firstly stained the tissue then the Biebrich Scarlet will binds with the acidophilic components of the tissue, after which when treated with the phosphor acids, the components that are less permeable will retain the red colour, because of the collagen this red colour is pulled out and at the same point of time causing a link with the collagen to bind with the aniline blue. . At the outset it must be made clear that the methods control how ionised acid dyes react with ionised basic tissues. 3.9.2 Material required: Bouin’s solution Xylene Graduated Alcohol (30%, 50%, 70%, 90% and 100%) Weigert’s iron hematoxylin solution Biebrich scarlet acid fusin phosphomolybedic-phosphotungustic acid solution Aniline blue solution 3.9.3 Protocol for MT Staining: Keep the Poly-Lysine coated slides on hot plate for 15-20 min. Dip in warm Xylene for 10 min twice. Pass the slide through graded alcohol 100% alcohol- (10 minutes) twice 90% alcohol (5 minutes) 70% alcohol (5 minutes) 50% alcohol (5 minutes) 30% alcohol (5 minutes) Dip in distilled water for 5 min. For formalin fixed tissue, re-fix in Bouin’s Solution for 30 minutes to 1 hr. at 56 ºC to improve the staining quality although this step is not necessary. Rinse in running tap water for 5-10 minutes to remove the yellow color. Stain in Weigert’s iron hematoxylin working solution for 10 minutes. Rinse in running warm tap water for 10 minutes. Wash in D/W Stain with Biebrich Scarlet Acid Fusin for 5 minutes. Differentiate in phosphophosphomolybedic-phosphotungustic acid solution for 10-15 minutes. Transfer the section directly (without rinse) to aniline blue solution and stain for 5-10 minutes. Rinse directly in D/W and differentiate in 1% Acetic acid solution for 2 minutes. Rinse slides, dehydrate through Alcohol Clean slides in xylene Mount with DPX mountant. NoteNuclei-Black, Muscle Fibre-Red, Collagen-Blue, Cytoplasm-Red Modified Immunohistochemistry 3.10.1 Principle: Immunohistochemistry (IHC) is the process whereby antibodies are used to detect proteins (antigens) in cells within a tissue section (for instance liver, pancreas or the heart). Immunohistochemistry exploits the principle that in biological tissues antibody binds to the specific antigens. This tool is used to localize specific antigens in tissue sections with labelled antibodies based on antigen-antibody interactions. This antigen-antibody interaction can be visualized in number of ways i.e., the immune reactive products can be visualized by a marker including fluorescent dyes, enzymes in general; radioactive elements or colloidal gold. This IHC technique is widely used by the researcher in basic research for understanding the differentially expressed proteins and for the localization and distribution of biomarkers in different- different parts of biological tissues. 3.10.2 Material required: Poly-Lysine coated slide. Xylene 1X- PBS buffer.(Sigma Aldrich Inc., USA) Graduated Alcohol (30%, 50%, 70%, 90% and 100%) DPX mountant for microscopy Acid alcohol (1% HCl in 70% alcohol) citrate buffer Sodium Borohydrate Hydrogen Peroxide Blocking solution Primary antibody Secondary antibody Streptovidin HRP 3.10.3 Protocol for Modified Immunohistochemistry: Cut the section of 3 to 5  µm.

Can Terrorism Be Defeated Only By Military Means Criminology Essay

Can Terrorism Be Defeated Only By Military Means Criminology Essay We blindly cant say that terrorism is the only option to reduce or stop terrorism without examining how terrorist groups end or fade out after some years. The governments in the other hand will have different options like military force, intelligence team, political negotiations and economic sanctions. The governments should prioritise their options on the terrorist organisations. According to a research, which examined more than 250 terrorist organisations from the period of 1965 to 2006, it found that many of the terrorist organisations ended because of the local police intervention like that of the Al-Umma organisation which carried out attack in Coimbatore during 1998. Many other organisations stopped their or dissolved their campaign due to intelligence or because of the settlements with the governments. It is to be noted here that military force did not have an adverse effect on the terrorist organisations to stop their violence against the non-combatants. United States stance on Al-Qaida proved wrong when the chief (Osama Bin Laden) was caught only by the intelligence force rather than the war on terror which lasted for more than a decade. Until the year 2006, there were around 648 terrorist groups and the research found that their survival for a longer term was due to the factors of economic condition, control type, their ideas, size and their goal. According to this research by Memorial for the prevention of Terrorism, it states that 268/648 groups ended within the year 2006, 136 groups fell apart because of difference in strategies and goals and the remaining 244 were active. The main reason for most of the terrorist organisations to quit terrorism was due to local police intervention and intelligence or a beneficial agreement with the governments to satisfy their needs for a particular group of people. Only very less terrorist organisations ended because of the military force. Military force was affective only when the terrorist groups were large and had the state-of-the art weapons to defend their goals and needs. The only place where military force turned out to be a good idea was in Sri Lanka when the government fought against the Liberation of Tamil Tigers Eelam (LTTE). This group demanded a separate land for Tamils in Sri Lanka which caused the biggest civil war in the history. Only in this case, governments action of using military force was beneficial because the opponent was well armed and had a large army to reach their goals. The research also found that the terrorist organisations which had some religious sentiments took longer time to stop their activities but rarely achieved their goals. Size of the group also determined their results. The example of a bigger group coming out victorious in terrorism was that of the army found by Mohammed, the founder of Islam which conquered Mecca in the Holy war or Jihad. The research also found that the terrorist from upper-income groups were nationalist and rarely were religiously motivated. COUNTERTERRORISM RATHER THAN WAR ON TERRORISM: After the September 11 attack by Al-Qaida on the World Trade Center, United States strategy to fight terrorism was mainly by the military action. They have also employed some non-military operations like reducing the foreign assistance and securing their states with more power. It was only during the Obamas regime, counter terrorism proved to be effective rather than the War on Terror Obama employed the intelligence squad to break in to or kill the al-Qaida chief in 2009. This initiative proved beneficial and the U.S killed their target in Pakistan on May 2, 2011. This made a way for many countries to withdraw the aspect of War on Terror and employ counterterrorism. As of 2008, the war on terrorism had not much effect on Al-Qaida as it remained strong and well organised. Its goal of uniting Muslims to fight the west remained strong and it continued to encourage terrorism to be employed in more places around the world. They conducted many such attacks without any problems when military attacks were employed on them. Military force only helped the governments to reduce some bigger attacks like that in New York or Mumbai. United States then decided to change their strategy to negotiate some political settlement with the Al-Qaida. As Al-Qaida was religious and fought the war against the west in the name of Allah, the negotiation strategy was not effective. So the governments should decide to abolish them by two strategies. They are: Governments should start to depend on intelligence and policing to destroy Al-Qaidas plans in attacking the non-combatants. Al-Qaida is a large group who are active around the world and commit some deadly acts only when a message is received from the head of the group. In order to track their moves and those peoples involved in the attacks, U.S has employed Central Intelligence Agency and FBI to track and demolish the terrorist activities with the help of foreign police and some intelligence agencies. The governments should also reduce their military personnel in the borders and promotes local forces to take charge as they had a greater understanding of the places. The main aim of this move is to promote counterterrorism as this proved to be effective than War on Terrorism in many countries who are fighting terrorism. This replacement in strategy also makes the terrorist think that they are criminals and not warriors who are fighting for the religious cause of Jihad. DEPENDING ON INTELLIGENCE: The U.S government should concentrate more on police forces and an intelligence agency at least after the Al-Qaida Chief was killed in the counter attack by the U.S Navy Seals. The governments should now focus on CIA, FBI and increase the budgets which specialises in counterterrorism. The military forces should have the same strategy for the groups involved in insurgencies and for large groups. According to Hoffman, he suggests the intelligence agencies to cooperate with the local police and the intelligence agencies in the countries where terrorism is prevailing to build more effective ways to combat them. Policing and intelligence are best suited to demolish the terrorist organisations like Al-Qaida because of their operation in many countries. These terrorist organisations are decentralised and receive funds and messages from a particular place to carry out a operation. The operations of these terrorist organisations are a little complex and have different nodes for operation. The se nodes can be easily identified and demolished only with the help of police and intelligence groups. The main drawback of this type of act is reducing the nodes of the terrorist organisation in many countries than in a single country. This method of counterterrorism is only possible only by the full support of the local police and the community unlike that in Pakistan. The terrorist organisations in the present days are easy to be demolished by the police and intelligence networks because of its structure. The terrorist organisations employ top-down or bottom-up approach to communicate between themselves. As the message needs to be passed by many people, it is easy for the intelligence agencies to track their location. These terrorist organisations dont get demolished if only the key members are caught or killed as in case of Al-Qaida. The terrorist organisations have a large network and can work without the commandments of the key leaders. These terrorist networks are active for long term because of its the presence of its hubs. The terrorist organisations get isolated if the hubs that send most messages are destroyed or demolished. These hubs are also easily isolated because it is considered as the information centre for the terrorist organisations. These hubs can be busted with good intelligence activities like tracking down the telephone lines, monitoring the email, couriers and fax facilities in countries like Pakistan. By these measures by the personnel, terrorist can be caught, arrested and enforced in the court of law. There are different steps involved in this kind of approach which include data analysis, capture of key leaders of terrorist organisations and amending the law in some special cases. For the list of above operations, police and intelligence agencies are best suited to do the acts. DATA ANALYSIS AND INFORMATION COLLECTION: Data collection and analysing the information proves to be one of the important aspects of intelligence bureau on terrorists. There are different ways in finding the terrorist activities. They are by human intelligence or by signal intelligence. The information got by the human network proves to be the most beneficial one. But it takes determination and patience to break up the human network of terrorists by recruiting the terrorists who are already in the terrorist groups. It is difficult to recruit the informants from the terrorist groups because of the faith and love for their friends and religion. According to an intelligence agency, it takes around 18 month for a terrorist to carry out any attack on the public. This period of establishment is the important period for the intelligence agencies to identify, arrest and reveal the plan of their action. Another source for the intelligence agencies could be from the fundamentalist mosques who oppose terrorism. They might prove to be useful recruits as they might provide some information on the relative or friends of some terrorist and their recent activities. Detaining some important individuals who are associated with the terrorist groups would make them less capable of launching some large attacks. If this case of detaining and arresting the individuals in a small terrorist organisation takes place, the other operator may lose confidence and become some mere criminals. Making these men mere criminals would be possible only with the help of media and the intelligence personnel and not with some counter attack by the military forces. Another difficulty that might be faced by international intelligence agencies is with the cooperation with the local police and intelligence agencies as they might have their internal security issues to be solved. The information got by human couriers wa s more beneficial than the signal intelligence. The top terrorist individual understood the drawbacks of using cell phones and internet to transmit some information to their hubs. So they decided to send the information through some trusted individuals who had been in the organisation for many years. Only by continuous monitoring by the intelligence agencies, the couriers can be caught and be beneficial. This was the case when the U.S Navy seals found out the whereabouts of the Al-Qaida chief Osama Bin Laden. The U.S intelligence agency spied on some couriers to find out and kill the chief. In this case open action by the U.S Navy was unavoidable because of the doubt he (Osama) tried to defend him by hiding behind his wife. Capture of Key Leaders: Another important way of counterterrorism is to capture their key leaders and punish them severely according to the law. The terrorist should be punished severely because they were involved in some deadly acts to kill the non-combatants in the particular country. The law should punish them in a way which should be as an example for the other criminal and terrorists in the country. This task also involves collection of evidence for some terrorists before producing the convict before the court of law. Producing an individual before the court of law for terrorism might not be easier as that of drug trafficking, it should have direct connection with the deadly acts. The capturing of terrorist in any position of their group hierarchy will reveal much important information about their future attacks. The communicating devices used by terrorist such as diaries, laptops and cell phones will provide some very sensitive information on the future attacks and the names of other group members. Fo r example, capture of Khan Muhammad with his laptop in 2004, revealed the plans of Al-Qaida to attack the gold mines in Pakistan and also some attacks on IMF and Citigroup buildings in United States. Another good example to prove this fact is that of capturing of Osama Bin Laden on May 2. In the recent news, it revealed that his diaries contained some very sensitive information about the Al-Qaidas links with other terrorist groups and their future plans to attack many places in the world. Other measures to combat terrorism: Other ways to stop terrorism is by the help of legal approvals. This process may involve accusing the acts of terrorist organisations such as recruiting members, buying of weapons from other countries. These legal procedures will help the intelligence agencies and the local police to stop the acts of terrorism by some means like freezing the bank accounts of the suspected terrorists, conduct searches by modern means and to interrogate suspects who pose a terrorist threat to the community as whole. Freezing the accounts of the terrorist organisations also help the intelligence agencies to get leads about their whereabouts. But nowadays, terrorist exchange the money to fund their operation through some third person in the place where the money should reach and this illegal activity is called hawala in Islamic terms. The money transferred by the hawala means is not recorded or taxed by the governments. Monitoring of the money movement from the terrorist organisation is a tedious task fo r the intelligence agencies.

Future of Oil Essay -- Essays Papers

Future of Oil Is the world on the brink of an oil crisis? I decided to look into this possibility, because it seems like a rather serious question, one that I would feel more comfortable about if I had enough information to at least form a fairly justifiable position. After all, the little I knew about the situation before conducting any research yielded one undeniable result: the issue is an extremely divisive one, with plenty of proponents on both sides of the argument. I decided to look first at the arguments of those who claim that a crisis is looming. George Monbiot summarizes the problem in the following succinct fashion: â€Å"The world's problem is as follows. We now consume six barrels of oil for every new barrel we discover. Major oil finds (of over 500m barrels) peaked in 1964. In 2000, there were 13 such discoveries, in 2001 six, in 2002 two and in 2003 none. Three major new projects will come onstream in 2007 and three in 2008. For the following years, none have yet been scheduled.† This, at first, seems like a rather startling discovery, but it’s its significanc...

A Reality In Fiction Essays -- essays research papers

In A Tale of Two Cities, Charles Dickens contrasts the Manettes’ life during the French Revolution in both London and Paris. The story follows them throughout the trials of the Reign of Terror in Paris, to the safety and security of London. He also compares the cities themselves, one being overrun with poverty and oppression, and the other being safe and economically sound. He shows the differences in the quality of life in both cities, while developing a love story in which the lives of the characters are twisted within the French Revolution. In France before the revolution, many changes had been made to help the country, but the Deficit of Revenue was not one of them. Many of the aristocrats and clergy were exempt from paying taxes, yet the poorer citizens were taxed heavily to make up for it (Carlyle vii). Louis XIV gave the upper class special power and privileges and ultimately caused France to weaken (Wright 31). Soon the common people were poor and starving. France had been suffering inflation for years; therefore, the government tried to tax the upper classes, but they refused to pay since they had been exempt for so long. Soon after, France endured many hardships, including drought and famine, and France became even poorer (Wright 31). In order to reform the financial status of France, Louis summoned the Etates-Generaux, who had not met since 1614. The Etates-Genereaux, or the General States, was a representative assembly that dealt with the matters of the state. It was made up of three groups: the church, the ari stocracy, and the remaining ninety five percent of the population (Wright 33). On July 14, 1789, the French Revolution officially began by the storming of the Bastille. The reason the Bastille was attacked was because it was seen as a symbol of the King’s power (Wright 34). This led to ten years of attacks made upon the privileged because of the abuses the common people felt from the ruling classes. Soon after the Bastille was taken, many other outbursts and riots occurred in France. Many aristocrats’ chateaux were burned, and this era of violence became known as The Great Fear (Wright 33). Many aristocrats and clergy fled the country in fear of being beheaded (Wright 34). Louis was put on trial as a traitor and was executed on January 21, 1793. Many people led revolts and provided the revolutionary ideas that the upper classes feared... ... but his future was clearly in England with his daughter and son-in-law (Kiran-Raw). The harsh conditions of Paris in the story were extremely realistic compared to the actual revolution. The people of Paris were starved and worked to death. They had to work more than they should have had just to pay what the government taxed them. However, in the story, all the revolutionaries were more violent than some of the real revolutionaries. Although there were violent ones, others were also people that had revolutionary ideas and views that could have helped the situation. Those people ended the true revolution.   Ã‚  Ã‚  Ã‚  Ã‚  A Tale of Two Cities is undoubtedly a realistic, yet fictional account of the French Revolution. Dickens compares and contrasts the lives and events of both London and Paris in a very accurate manner. His intentions of writing to enlighten people of the history of the revolution were successful, while also extremely entertaining. Although it has been thought that Dickens created the characters out of people he actually was associated with, they fit the story properly. The story truly digs into the heart of the revolution and the people it affected.

A fence should not be built on the U.S. – Mexican Border

The U.S. should build a wall between itself and Mexico, topped with razor wire. This is about toughening immigration laws and the strict enforcement of laws already widely discussed.The building is a two thousand-mile-long fence would cost about 680 (m) million dollars, and it would slow border crossings. It is for the idea of candidates running for president to have clear and aggressive plans for dealing with immigration.It also gives the idea of doing something that might actually work to stop illegal aliens from flooding into the United States is actually drawing great interest. It won't go away. Illegal immigration is not just impacting the Border States. Illegal aliens are showing up everywhere. Constitutionally it is a Federal responsibility to protect the 50 states from invasion and as a practical matter it is impacting all of us.Background:â€Å"For those people who do not live in the U.S. of America or have not heard about it, U.S.A. government has decided to construct a wa ll along the border of Mexico to attempt to keep out illegal and MS13 clan members. The MS13 is a dangerous clan that specializes in smuggling drugs and people across borders and has made their way from Columbia to Northern Mexico and intend to get into The U.S. of America.Also, there have been reports of the AL Qaida attempting to get the MS13 to smuggle THEMSELVES into the U.S. of A. so they can continue their reign of terror. The Mexican government feels that it is unnecessary that there is building a wall and have started comparing President Bush to Hitler because of the Berlin wall.Personally think that the wall should be built to protect American from the MS13 and to control the amount of illegally migrating to the U.S. of America (â€Å"All to Protect the Innocent†.Tue January 24 2006 20:02. http://forums.ubi.com)†.Immigrant or a refugee rights groups across the country are now moving in the direction of putting immigration in the context of a global economy, glo balization, and people on the move escaping poverty, hunger, civil war, and persecution. NAFTA (the North American Free Trade Agreement) kicked off that trend.When it was testified at the NAFTA hearings that Mexican and Aliens complained of why they weren’t including immigration in the context of a financial free trade agreement. Why were they focusing on the free movement of merchandise but not on the free movement of people? Basically it's a labor issue.California has always been impacted tremendously by immigration, not just by people from Mexico. It’s now estimated even by the INS (Immigration and Naturalization Service) that there are at least five million immigrants in the U.S. who are undocumented. California usually comes in with at least half of those immigrants, not only because of its juxtaposition to Baja California, but also it's a place where people can blend into cities like L.A. and San Francisco. There's about nine million in these cities and about a t hird are immigrants and refugees.It is important that it begins addressing immigration within the context of a global economy. Globalization affects the United States because investments in other countries have impacts such as people leaving that country, the displacement of jobs, jobs moving in and out of a country.Primarily focuses on human rights and nowhere is human rights more impacted than on the U.S.-Mexico border. These have really been a hateful time for Americans especially with the shooting incident by the military.Right after that, other military operations were exposed, including here inCalifornia where National Guard troops have been out in camouflage, hiding in the brush on the pretext of looking for drugs and immigrants. In addition, there has been introduced legislation in the House to send 10,000 military troops in to California.This is in addition to 5,000 Border Patrol agents approved by Congress. That's going to interrupt a lot of movement. It could eventually i nterfere with free trade because how long will Mexico put up with this confrontation by the military on the border.Going back to history, the U.S. contracted with Mexicans to come to work here in the '30s and '40s and '50s. Then the xenophobia started, the scapegoat, and you had massive raids and deportations of hundreds of thousands of Mexicans. U.S. citizens and legal residents as well as undocumented were all sent to Mexico in the '30s and '40s and '50s.During '50s, operation wetback, and even though I'm a fifth generation U.S. citizen, right on these streets around here I used to be stopped on the way home from school, or visiting my girlfriend, or going downtown. The police used to smack me up against the wall and call the Border Patrol. They get used to do in at least every other week. They used to take out of jobs, after school jobs, in restaurants, hotels by among Mexicans

The Case of the Omniscient Organization

Case Analysis The Case of the all-knowing Organization Introduction In this elusion study, Dominion-Swann (DS) has implemented a radical restructuring of the bend environs in suppose to recoup control of its employees. By 1990, DS had been distraint from a number of melody woes. It was not keeping pace with its competition, employee turnover had increase substantially, health costs and work-related accidents were rising, and employee theft was at an all-time high. Instead of identifying and addressing the underlying business and sellment problems, DS decided to direct the symptoms by turning to SciexPlan Inc. o jock radically restructure the work purlieu with the use of employee manageing applied science. oscilloscope DS has adeptified its work purlieu restructuring based on past failures earlier than future goals for success. The company has stoold a form to compile a comprehensive database of selective education on both employee. DS overly monitors its employees in all expressions of their job, subjecting them to constant evaluation and productivity tests. The massive kernel of reading collected on each employee is suppositional to forfeit DS to objectively manage personnel and project job assignments that fork out the greatest efficiency.Instead, DS has created an im individualized supervise, supervision, and detective work brass knowing to lay traps for employees and word form their behavior without any managerial effort. job Statement Has DS become so consumed with its radical restructuring of the work environment that it has prioritized technology and control over the welf ar, creativity, and productivity of its great deal? Analysis and Issues Digital technology has do an undeniably profound impact, both plus and negative, on the study. When implemented properly, the benefits of this impact sess include increased productivity, improved safety, fail working onditions, and enhanced communications in the mi dst of employees, management, and customers. However, an exceedingly obsessive employee observe system result create tedious and nerve-racking working conditions, loss of employee cover, and fear which bequeath result in reduced levels of creativity and productivity. By implementing an overly zealous system for employee monitoring, DS is significantly aggravating the accent that exists in the midst of surveillance technology and employee screen concerns. DS wants to monitor employees in order to reward effort, knowledge, productivity, and success while eliminating idleness, ignorance, theft, and failure.Instead, it is treating its actors exchange satisfactory pieces of equipment rather than unique and valuable individuals. DS has basically transformed the workplace into an all-inclusive electronic prison where nearly all aspect of an employees behavior is monitored. The DS managers who monitor every move that employees make are accomplishing efficiency objectives at a larg e cost. Monitoring and surveillance can create a high stress environment for employees that can lead to physiological and mental stress-related illnesses. Covert surveillance at DS will do nothing that increase fears, anxieties, and distrust among employees.The im individual(prenominal) aspect of technological surveillance diminishes employees concepts of their value, contribution, and self-importance-worth. The all-encompassing surveillance implemented by DS will destroy any hope for employees to make decisions and act autonomously. Autonomy is a particular component to on-the-job independence that maximizes worker esprit de corps. Although DS has justification for some fare of employee monitoring in order to successfully evaluate employee doing, it has taken employee surveillance to the heyday where it will adversely affect productivity.When employees do not feel that they are trusted, their appetite to perform well is less(prenominal)ened. The employee screening movement DS has implemented brings up extra concealment concerns. Any investigation of employee activities and tarradiddle outside of the workplace is an extremely mass medium and potentially litigious issue. DS is entirely justified in intruding into its employees personal lives when it involves mis exonerate or illegal activity.Off-duty conduct may be relevant to troth if the misconduct negatively impacts the employees work carrying into action or the companys mission. However, the systematic monitoring use by DS raises serious privacy concerns. Monitoring all employees activities, rather than just the activities of employees under suspicion of specific misconduct, constitutes a blanket search that brings enormous privacy concerns. Recommendations DS would be better run into with no employee monitoring rather than scrutinizing its employees every move.Once the employee monitoring creates a morale problem, all of the value it has created will be diminished. If DS is to continue wi th employee monitoring systems, it moldiness create and clearly communicate a monitoring policy for employees. DS postulate to start with human-oriented policies, then use technology to enforce them. As it stands right now, DS is exerting too much power in its invasion of employee privacy in the workplace. DS is exploiting the lack of regulation in this region in order to implement extremely invasive methods of employee surveillance.Until employees are protected by regulation to protect their rights to privacy in the workplace, DS should assume responsibility to self regulate by limiting the amount of surveillance, implementing it only when it achieves specific goals for success. Monitoring should be conducted only for business purposes, and this essential be communicated to the employees. In order to throttle foul its employee monitoring system to a tenable level, DS should review and apply the suggested rights stipulation by the American Civil Liberties legal jointure (ACLU ).To establish a reasonable border on and prevent abuses, DS should adopt a human-oriented policy that includes the following features * notice to employees of the companys electronic monitoring practices * use of a auspicate to let an employee know when he or she is being monitored * employee access to all personal electronic data collected through monitoring * no monitoring of areas designed for the health or comfort of employees * the right to dispute and delete inaccurate data a ban on the sight of data unrelated to work performance * restrictions on the disclosure of personal data to others without the employees consent (American Civil Liberties Union, 1997). DS should overly consider whether or not monitoring is truly necessary for performance evaluations. DS does not need to watch an employees every move to be able to judge the quality of his or her work. mathematical process monitoring should be far less of a concern than an employees superpower to complete tasks and co nsistently meet deadlines. DS should involve its employees on the decisions regarding when, how and why electronic monitoring needs to takes place. Most significantly of all, DS must allow employees to inspect, challenge, and, when necessary, adjust the data gathered or so them or their performance. Conclusion/SummaryDS must strike a balance between its business interests and its employees privacy interests. This balance should allow for surveillance under certain check conditions, and utilize less intrusive approaches. Although it is marvelous that DS would completely discontinue its monitoring practice, at a minimum DS should continue to fully inform its employees about all surveillance tools being utilize in their workplace and provided them with clear information as to what management does with the data.References Pedeliski, Theodore B.
