IT - Radio Frequency Identification - Essay Example This arises because of the simple reason that an wireless monitoring system is capable of checking the work that a person does or claims to have done in addition to even the personal chores that one might attend to. It is like any other personal monitoring system, like say a video-graphy station in a parking lot. There will of course, be occasions when the monitoring station infringes in to the privacy of the individual. The user of such devices has to exhibit caution and responsibility in addition to technical prowess. RFID comes under two basic technological models. One, we call the passive RFID tag and the other an active RFID tag. While the passive RFID tag has a pretty long life with no supporting batteries inside the tag, the active RFID tag has a battery inside it which makes the life of the tag relatively lesser though the power consumption of such tags are very small1. The corollary of such a limited life is that, the RFID tags cannot be embedded permanently inside any object or an animal body including man. If it has to be done, then it has to be a passive tag. The passive tags have another major limitation being that they cannot be read from a distance that is greater than two feet effectively. There are passive tags that are supposed to read even from greater distances but are not found effective. Technologically this limitation arises because of the fact that the RFID tag uses the induction technology of the radio frequency waves. There is always an RFID reader that is placed at strategic points. These readers emanate radiations all around and get triggered once it senses a response. These readers are generally directed and emit radiations only in one direction. In case of a passive tag, the waves sent out by the reader induces a current in the tag itself. This powers the operation of the tag and it passes to the reader a specific number or identification that forms the basis of communication between the two. However, in case of an active tag, the active tag receives the signal and is able to boost it and send it back to the reader. Since this has an internal source of power, the active tags can respond to even very feeble signals from the readers. This is the reason why while passive tags can be read out of a distance of one and half feet to two feet, that of the active tag is much more. And as we have seen earlier, the same reason also has a disadvantage that of life time limitation. RFID provides its users the facility of storage, retrieval, erase and rewriting of the data in the RFID tags from the remote reader. This makes the RFID immensely powerful and enables it to have details like the entire patient history in case of hospitals, payment histories in case of customers / vendors and production data in case you need to monitor the work in progress. Remote reading and writing of data into the RFID tags also make it the right kind of tool to monitor animals in a farm and assets or library books that are issued and returned or routed to some body else. All these are massive advantages for industries. However, these can also be misused by having and storing data that goes into the

Elite Running Inc Case Study Example | Topics and Well Written Essays - 1000 words

Elite Running Inc - Case Study Example The inventory of Elite rose by 39% in 2003 as compared to 2002. The rise in the level of inventory was preplanned by the management in order to be prepared to grab the offers from the suppliers when they offer favorable prices for the company. The changes also indicate that while the sales have declined for the company by 24%, the gross profits have declined by 53.8%. This fall in gross profits was mainly due to the changes in the product prices due to the change in competitive market scenario with the appearance of a new entrant named, Stampy. The other significant changes include fall of retained earnings of the company by 11.2% and the fall of equity by 8.4%. Explanation for tick-marks b, e & k The explanation for the tick-marks has been explained as follows. Tick-mark b The fall in the accounts receivable of Elite Running Inc. in 2003 as compared to the value of 2003 could be explained by the fall of sales figures of the company. Due to the fall in the level of sales volume of th e company, the credit offered for sales also reduced. Thus the accounts receivable also declined in 2003 as compared to 2002. Tick-mark e The inventory of the company increased by 17 million dollars which is a rise of 39% in inventory level of 2003 as compared to that of 2002. ... Tick-mark k Elite running Inc. has faced unprecedented competition in 2003. The management forecasted a 10% rises in the sales as compared to 2002. However, due to entry of a new competitor and offers of a similar footwear and apparel product by the competitor eroded their market share as the customers inclined towards the products offered by Stampy. This led to the fall of revenue earnings of the company. In order to respond to the changed external environment, the company reduced its product prices. Although, it allowed the company to retain a large number of customers, the gross profit of the company declined. Discussion: auditing and accounting issues for identified changes The accounting and auditing issues identified in the valuation accounts receivable suggest that the valuation of accounts receivables should have been $51m instead of $60m that has been recorded in the books of accounts. The issue behind this gap is that the management has influenced the accountant and the aud itor in disclosing consistent value of aging account (AICPA 18). The accounts receivable figure for a period of less than 30 days has also been suggested to be maintained at 85%. In order to do this, the accounts receivable from the three sales transactions of the new sales and marketing tool of the company, named Andy Dufresne has not been recorded under the assurance of the management. This is an auditing issue as it shows clear deviation from standards of accounting (U.S. Securities and Exchange Commission 1). The accounting and auditing issue involved in the rise of inventory level of Elite Running Inc. questions the gap between the available information on the receipt of supplier materials as the reason for rise in inventory and the

Drosophila Immunohistochemistry Practical

Drosophila Immunohistochemistry Practical Abstract Immunohistochemistry uses monoclonal antibodies to detect specific proteins in tissue samples with a visible label. For this practical, immunohistochemistry was used to visualise the distribution of protein in the 3rd instar Drosophila melanogaster larvae brain. The distribution of protein was visualised using a primary monoclonal antibody, and this primary antibody was then detected by a secondary antibody. Detection of the secondary antibody is via an enzyme reaction which produces a coloured precipitate. The secondary antibody used is a monoclonal antibody that recognises IgG from a mouse which is attached to alkaline phosphatase. Looking at the protein distribution pattern in the larval brain the antibody used was detected. Brain samples were fixed in 4% paraformaldehyde in phosphate buffered saline (PBS) at room temperature for 20 minutes, then washed four times with PBST prior to blocking with 10% donkey serum for 45 minutes. The primary antibody was added, and the brains incub ated at 4 °C overnight. The antibody used was embryonic lethal abnormal vision (ELAV). This is because there are domains in the optic lobe which look like dots and webs from binding of ELAV to the specific proteins in the brain. Introduction Immunohistochemistry is the use of monoclonal and polyclonal antibodies to detect specific proteins in sections of tissues. Applications of immunohistochemistry has been used by pathologists for the diagnosis of cancers. This is because certain antigens particularly tumour antigens are expressed in certain cancers (Kaliyappan et al, 2012). The main principles of immunohistochemistry include a primary antibody which binds to a specific protein of interest. Then a complex of an antibody binding to a specific protein is formed from incubation with a secondary antibody. Finally, in the presence of a substrate and chromogen, an enzyme catalysis happens to generate a coloured precipitate at the antibody-protein specific binding sites (Immunohistochemistry.us, n.d.). Monoclonal antibodies are specific antibodies produced by a B lymphocyte cell which recognises a specific protein such as an antigen. Polyclonal antibodies on the other hand are antibodies produced by a collection of different B lymphocytes. They are able to recognise specific epitopes on an antigen (Lipman et al., 2005). Primary antibodies are antibodies which bind to a specific antigen. Monoclonal and polyclonal antibodies are classified as primary antibodies (Cheriyedath, 2016). Secondary antibodies are the antibodies which bind to the primary antibody to allow detection of the primary antibody under a microscope (Rockland-inc.com, n.d.). Primary and secondary antibodies are used because primary antibodies detect a complimentary protein which is of particular interest whilst the secondary antibody is raised against immunoglobulins associated with the primary antibody. The secondary antibody then associates with a linker molecule which then recruits reporter molecules or the antibody binds directly to the reporter molecule. Drosophila is used as a model organism because their genome is very closely related to the human genome. This means that human genes can be mapped to drosophila genes. Genes in human s which cause disease are also in drosophila. Many generations can be observed in drosophila because they have a short reproductive cycle. They are small so a lot of them can be kept in a laboratory. Fruit fly genes can be altered very easily. Transgenics can be easily produced in the flies and studied. A huge amount of biology is known for these fruit flies due to a lot of research and history in these flies (Jennings, 2011). Tumour-associated stromal cells can act non-autonomously to produce epithelial cancers. Using the drosophila model organism mutations have been identified in the human tumor susceptibility gene 101 (Tsg101) as a cause of these cancers. The Tsg101 homolog leads to Notch signalling and secretion of the JAK-STAT ligand, making neighbouring cells to grow. Drosophila serves as a model for cancer. The most present malignancies in the central nervous system include gliomas. Pathways for the gliomas in drosophila using the GAL4 system causes glias to increase and dama ge brain cells. (Spradling et al, 2006). The aim of this experiment was to use immunohistochemistry in order to detect protein distribution in the brain of the third instar Drosophila melanogaster larvae. By analysing the immuno stained sample the primary antibody used can be detected. Methods Steps of immunohistochemistry include: tissue preparation by fixation, protein retrieval, endogenous blockage and antibody labelling. In tissue preparation, tissues samples are preserved so protein and tissue architecture does not breakdown. Samples may be also need to be perfused for prevention of detecting non-specific proteins which can interfere with the detection of the target protein. In order for protein and tissue to not breakdown fixation is required. Steps of fixation include perfusion, immersion and freezing. In perfusion, tissues are perfused with a fixative to allow rapid fixation. During immersion tissues are immersed in the fixative to allow the fixative solution to diffuse through the tissue or cell sample. In the final step samples with protein that cannot survive fixation are frozen in liquid nitrogen whilst being embedded in a cryoprotective embedding medium. Once fixation is done the sample needs to be sectioned and mounted. The tissues which have been fixed with a paraformaldehyde solution are sectioned into slices which measure 4-5 µm using a microtome. After sectioning the sections are mounted onto a glass slide which is coated with an adhesive. Once mounting has been done the sections are dried and then deparaffinization takes place (Thermofisher.com, n.d.). The next major step is for the target protein to be retrieved. Paraffin is removed in order for the antibodies to reach the protein. Heat induced epitope retrieval is the most common used method to retrieve these proteins. This involves heating the slide at PH6 or PH9 depending on the antibody (Biosciences, 2014). Endogenous blocking needs to place because reagents which are present during immunohistochemistry are also present in cells. This can interfere with protein detection because of unwanted signals being produced that mistakenly detect an protein. Finally, the antibodies are labelled to detect the target antigens. The primary and secondary antibodies are diluted into a buffe r in order for the antibody to be stabilised. Rinse buffers are used between antibody applications to remove unbound antibodies (Thermofisher.com, n.d.). Once they are labelled the samples are viewed under a microscope (Biosciences, 2014). Results The primary antibody based on the protein distribution in the drosophila brain sample is the embroyonic lethal, abnormal vision (ELAV). A`ntenna A pair of appendages used for sensing. Eye disc The raised disk on the retina at the point of entry of the optic nerve, lacking visual receptors and so creating a blind spot. Optic stalk The constricted proximal portion of the optic vesicle in the embryo which forms the optic nerve. Optic lobe The lobe in the midbrain from which the optic nerve partly arises. Ventral nerve cord A chain of connected segmental ganglia which lies against the body wall in the body of the drosophila. Discussion In this practical, distribution of protein in the 3rd instar Drosophila melanogaster larvae brainwas detected using a primary antibody which binds to the specific antibody. Using a secondary antibody, the protein distribution was able to be visualised under a microscope by binding to the primary antibody. Based on the protein distribution visualised under the microscope the primary antibody used to bind to the proteins to produce the protein distribution was identified. The identified antibody was ELAV because there are domains in the optic lobe which look like discrete dots and webs. Embryonic lethal abnormal vision protein (ELAV protein) is a protein which binds to RNA thus an RNA binding protein expressed in brain cells of drosophila after birth. Repeats of an RNA binding domain approximately 80 amino acids in length is in these RNA-binding proteins. ELAV distribution has a similar distribution to many different splicing factors. Variants of genes which are correctly spliced in neurones are regulated by this ELAV protein. Additionally, this ELAV protein plays a role in the formation of the n-arm transcript of the drosophila armadillo. It is generated by splicing from exclusion from exon six of the ubiquitous arm. In mutant ELAV the amount of n-arm is reduced (Broody, 1996). Mutant ELAV have a short life span (Toba et al, 2010). Loss of function alleles for ELAV causes the drosophila embryo to be lethal with also mutant embryos having an abnormal neuropil. Also mutations produce abnormal eye structures, defective electroretinograms and flight defects. Mutant clo nes analysed in mosaic flies has shown that there is a post-embryonic role for ELAV for photoreceptor cells, optic lobe and associated neuropil areas to maintained. Because of this, phenotypes that appear to be a mutant has a role for ELAV in the formation and maintenance of the nervous system (Koushika et al, 1996). Significant divergence between humans and mouse has caused orthologous disease genes to arise. Orthologous genes arise due to speciation in homologous genes. An example is the TDP1 gene. This is a gene which has a role for Topo I DNA complexes to be repaired. TDP1 orthologs for expression in the inside of cells with localizations has been located in the cytoplasm and nucleus. Mutations in the TDP1 gene has been seen to have a causative link to spinocerebellar ataxia with axonal neuropathy (SCAN1) disorder. This mutation is not present in mouse ortholog. TDP1 expression in human and mouse are different and produce different phenotypes. Selectins P and E for inflammation is different when compared between humans and mouse. The orthologous human version of selectin P from mouse does not have the pathway needed for regulation (Gharib and Robinson-Rechavi, 2011). Immunohistochemistry is a useful technique because it is used in research and pathology laboratories where immunohistochemistry can help with diagnosing neoplasias and pseudo-neoplastic lesions (De Matos et al, 2010). IHC is used to test efficacy of pharmaceutical drugs by detecting the activity or the regulation of disease targets. Immunohistochemistry is a technique specifically for detecting proteins such as antigens in a tissue sample. In situ hybridisation involves finding the location of targets for specific nucleic acids in tissues and cells which have been fixed to gain information for expression of genes and genetic loci (Ncbi.nlm.nih.gov, n.d.). RT-PCR is used for RNA expression analysis. Knowing the mRNA is important to understand what gene it is and protein distribution allows us to understand what affect the gene has in an organism. Questions   Ã‚   The point of fixation is to fix the tissue sample so that putrefaction and autolysis does not occur. Fixation allows the tissue sample to kept in its natural state. This is important so that the structures in the cell do not fall apart and diffuse away. The fixative used in fixation disables intrinsic biomolecules, protects the tissue from extrinsic damage and also alters the tissue on a molecular level to increase their mechanical strength and stability. The step is very critical because proteins need to be localized because otherwise they will diffuse away from their initial location. Protein immobilization occurs before translocation. The final thing for fixation is that it achieves the most rapid reaction possible at a low temperature (Berod et al, 1981). Antibodies bind to epitopes on their complementary antigen. However sometimes these antibodies can bind to non-specific antibodies that is similar to the binding site on the target antibody. Because of this binding of non-specific sites, background staining can be created that can mask the detection of the target protein. To get rid of this background staining tissue samples are incubated with a buffer that blocks the reactive sites which are not 100% complimentary to the primary and secondary antibodies (Thermofisher.com, n.d.). NTMT solution is a buffer used for the blockage of non-specific binding sites (Ebioscience.com, n.d.). The colour reaction is the final step which involves visualising the tissue sample where a specific antibody binds to the tissue sample. After this the primary antibody is detected in two ways, directly or indirectly. The direct method is the colour producing reaction. The primary antibody is tagged with a peroxidase enzyme which is used in a reaction to generate a coloured product (Heyderman, 1979). Bibliography Berod, A., Hartman, B. and Pujol, J. (1981).

Love Despite Dominance in Like Water for Chocolate by Laura Esquivel and The House of Bernarda Alba by Federico Garcia Lorca :: Compare and Contrast

Literature often words complex phenomena, which otherwise possibly remain ignored. One example of such complex phenomena is the coexistence of two contradictory elements, dominance and love. Dominant personalities in Like Water for Chocolate and The House of Bernarda Alba, Mama Elena and Bernarda Alba respectively, do not explicitly display love towards their daughters, but it is revealed by their behaviour and uncharacteristic actions. Some elements of characterization or narrative mode in both the works try to limit the reader’s perception of the dominant personalities to their static characteristics. In Like Water for Chocolate, we are told the story from a limited subjective third person point of view. Tita’s grandniece is a limited narrator, who knows absolutely everything about a single character of Tita and every piece of knowledge in that character's mind, but it is ‘limited’ to that character – that is, things unknown to the focal character (Tita) are not described. So, this point of view may be considered unreliable. The presence of Tita’s hatred towards Mama Elena almost throughout the book, and the portrayal of Mama Elena as a ‘haunting’ character as a ghost, also contribute to limited perspective of the work. We are presented with only one static feature of Mama Elena. In The House of Bernarda Alba, even though the use of dialogue broadens the range the perspectives, Bernarda’s dialogue compared to that of others is limited. The fact that there is no soliloquy with Bernarda can imply a limitation to the perspectives open to the reader. We are shown only the dominant side of Bernarda’s character. The hatred of Poncia, who is one of the few characters shown from different perspectives, towards Bernarda can also be considered as a limiting factor of the perspectives. Thus, the reader’s perception is narrowed down. While Mama Elena and Bernarda Alba are seen as tyrants from a rather narrow perspective, they can otherwise be seen as traditionalist mothers. From this fresh perspective, it could be argued that Mama Elena is nothing more than an orthodox mother who assorted to cruel methods including corporal punishment to mould her children in her own best way. From Mama Elena’s perspective, she makes choices that are, as she â€Å"[thinks] best for [them]† (p. 167). This perspective is particularly relevant to the upbringing of Tita: â€Å"Magi never brought [Tita] what she asked for, but instead what Mama Elena thought best for her.† (p. 167) Mama Elena’s character as a traditionalist mother is further revealed from specific incidents: providing Tita something â€Å"better† than Three King’s Day Bread, forcing Tita to re-sew her stitches because she did not baste it (p.

Adults’ Effective Behavior Management among Children with Delays

Effective behavior management among children with developmental delays is an essential element of special education. This needs to be administered by adults in the early childhood to form a firm foundation of the acceptable conducts and desirable activities of special children. It is through a successful behavior management that the concerned children would be able to behave appropriately in the future.In addition, a well-managed behavior of children with developmental delays allows for a smooth performance of adults’ roles, thereby providing help and the much needed care for these special children.It is therefore necessary for parents, teachers, service providers, and related professionals to adhere to and uphold an efficient behavior management among children with developmental delays because this leads to the achievement of beneficial outcomes. This premise is what chapter 13 of the book â€Å"An Introduction to Early Childhood Special Education: Birth to Age Five† b y Linda Dunlap (2009) particularly imparts to the readers.Chapter 13 of the book entitled â€Å"Behavior Management† emphasizes the need for behavior management in an effort to address and eventually resolve issues concerning how children with developmental delays behave toward other people and within a specific environment. In this chapter, Dunlap (2009) provides the public with vital pointers to consider which would be helpful in carrying out an effective behavior management of children with developmental delays and those with related developmental concerns. Key Points The 13th chapter of the book can be better understood in light of the fundamental components of behavior management.According to the author, the key points of behavior management include an emphasis on the positive rather than negative conducts of children with delays. That is, the effectiveness of behavior management lies on the ability of both adults and children with delays to bring out and improve desirab le and valuable behavior. In doing so, the effort leads to the elimination of undesirable conducts because it is those which are only appropriate that would remain and would be provided room for development (Dunlap, 2009).When the desirable behavior of children with delays is developed, the purpose of assisting them to create and improve techniques to deal with their personal behavior is eventually achieved. This condition leads to the next vital point which is the need for diversified and efficient behavior management strategies that would be definitely helpful and valuable for children with delays (Dunlap, 2009). Dunlap (2009) also explores the establishment of logical expectations of adults surrounding children with delays, such as their parents, teachers, and professionals dealing with developmental concerns, as part of behavior management.These logical expectations involve taking into account the respective growth stage of each child. Most important among these key points is th e principle which must always be remembered by adults. That is, children with developmental delays use and react to behavior management strategies that are similarly suitable and beneficial for normal children (Dunlap, 2009). Desirable Behavior Dunlap (2009) begins her discussion of behavior management by emphasizing the value of desirable behavior among children with delays.She claims that regarding desirable behavior with an undeniable relevance is necessary to bring out and likewise develop or maximize whatever sought-after attitudes and activities that a child with delays shows. While it is apparently more complicated to manage the behavior of children with delays compared to the behavior management of normal children, the principle and practice of developing their desired behavior would aid in the success of behavior management (Dunlap, 2009). In underlining her point, Dunlap (2009) explains that it is the desired behavior of children with delays that must be improved.She belie ves that it is better to develop positive conducts and activities rather than to dwell on the negative or undesirable behavior of children with delays. As more emphasis is given to the development of desired behavior, this would be beneficial to both the adults and children. Simply put, an effective behavior management of children with developmental delays not only presents the harms of negative or inappropriate behavior, bur it also emphasizes the benefits of manifesting positive and desired behavior (Dunlap, 2009).In this chapter, Dunlap (2009) presents several situational examples which explore and stress the significance of encouraging and developing desired behavior among children with delays. Adults play an important role in such instances. Dunlap (2009) explains that â€Å"adults need to provide instruction, coaching, and modeling with regard to appropriate ways to interact with others† (p. 391). It is through these roles that adults are able to inform children with de lays the need for them to show desired behavior.The author adds that when the importance of desirable behavior is realized, it becomes natural for children with delays to portray such. Dunlap (2009) concludes this topic by emphasizing the need to: (1) consider more appropriate rather than inappropriate conducts; (2) consistently respond to the challenging behaviors of children with delays; and (3) ensure that adults’ expectations are developmentally appropriate with the things given to children . Behavior Management: Principles and Practices This is the portion of Chapter 13 where the heart and soul of behavior management are discussed.Dunlap (2009) states that the general principles in handling the behavior of children with delays include several considerations: (1) not controlling the conducts or attitudes of children but rather respecting their ability with regard to managing their respective behavior; (2) positive or encouraging way of behavior management; or (3) not subj ecting or overloading children with negatives; (4) reassuring children of their value; (5) avoiding personal attacks on children; (6) changing adults’ expectations as children behave differently and have their individual needs; (7) taking responsibility of the special children’s management; (8) imposing necessary rules and even punishment; (9) modeling appropriate behavior for the benefit of the special children; and lastly, (10) establishing a positive learning setting to encourage desirable conducts (Dunlap, 2009). Behavior that Needs to be Changed The relevance of the mentioned principles is reflected in the fact that through such efforts, the adults involved in behavior management will be able to identify which among the behaviors exemplified by children need modification. Dunlap (2009) explains that while it is uncalled for to â€Å"go to war† with children with delays (considering they already have developmental concerns), it is still necessary to change s ome of their behaviors (p. 397). This especially holds true if the behavior is deemed as detrimental to the child’s development and his or her manner of interaction with others.Hence, those which warrant change and intervention include the conducts that: (1) require disproportional level of attention and time; (2) interrupt others and forbid learning to happen; (3) become more difficult to handle; (4) are supposedly common to much younger children and not to school-age children; (5) result in harmful personal image; (6) are negatively viewed by other children; and (6) threaten the problem child and his or her classmates (Dunlap, 2009). Behavior Management Strategies To strengthen the performance of behavior management, Dunlap (2009) presents several strategies. These techniques serve as specific factors that may help adults to succeed in handling the behavior of children with delays. One of these techniques is reinforcement. Its implementation is valuable in the development o f appropriate conducts among children. Regardless of whether it is a primary or secondary kind of reinforcement, Dunlap (2009) reminds the adults that children vary in a number of aspects.Hence, this specific strategy must be flexible and depends on the character of a child (Dunlap, 2009). Another technique is redirection which orients children on the appropriate conducts instead of the inappropriate ones. Behavior management also entails subjecting children to what is called â€Å"time out. † While similar to redirection, making children experience a time out is like taking them to inappropriate scenarios where their behaviors are challenged and relocating them to a place or situation where they can calm down. The ultimate goal of this strategy is to prevent children from doing further violations while at the same time instilling in them the need for them to be disciplined.Extinction pertains to simply ignoring the inappropriate behavior of children until they calm down and the situation is settled. Lastly, as mentioned earlier, punishment is essential and is an effective strategy as unfortunate situations resulting from the inappropriate behavior of children need to be dealt with even in a rough manner. In conclusion, the author presents the success behind Project SUCCEED or â€Å"Supporting and Understanding Challenging Children's Educational and Emotional Development. † Dunlap (2009) uses this project as an example to prove where effective behavior management existed because its principles are all aimed at instilling appropriate conduct among children (Dunlap, 2009). ConclusionAn effective behavior management, especially in the early childhood or early years of children with delays, is indeed an important function or obligation that adults must consider. As Kay (2006) states, the proper handling of children’s behavior in their early years is a relevant concern specifically to those directly involved in such endeavor. This realization i s attributed to an increased number of children, including those with developmental delays, now engaged in pre-school environment. This condition results in more terrible and relentless conduct-related problems; thus, an effective behavior management of children with delays is highly important (Kay, 2006).The 13th chapter of Dunlap’s book is a valuable text, for it provides relevant information and reasonable explanations that are essential in the successful performance of behavior management. Beyond the specifics however, it is the undeniable value of the material that makes it helpful for both adults and children with delays. Ultimately, behavior management is not only a text in a book but is a strategy that needs to be carried out so as to realize its beneficial impacts. References Dunlap, L. (2009). Behavior management.

Through the analysis of Obama’s speech it will be seen that how dominant forces exercise their power, maintain their superiority and show their dominance.In this study it is tried to show that how come dominant forces or groups adopt strategies which fulfill their personal interests. In other words through the application of critical discourse analysis the text is analyzed to see up to what extent dominance and power is seen in the words and speech of those in power. CDA always aims at exploring the way social power abuse and dominance are enacted in society. Words are not to be considered neutral but as having some particular meanings which are not always obvious to all readers. Keywords: CDA, dominance, Obama’s speech, Power, Power realations 1. Introduction:Language is a phenomenon which is related to our social and cognitive development right from our childhood and plays a very crucial role in the formation of our identity. Whatever we say always contains some meaning and repr esents our perception toward a certain thing or idea. Language plays a very important role because every action particularly a political action is accompanied and in fact influenced and played by the language we use. We have always got a particular way of understanding and perceiving language. And the way we perceive language builds the foundation of our social construction and individual as well as group relationships.And some branches of linguistics have tried to explain that what kind of relationship is there between the use of language and importance of perception. Because the way we make use of language tells our intention toward any important issue either political or social. Any discourse either spoken or written can emerge from many sources like cultural, social or power background. Language has always its surface and real meanings and surface meanings differ from that of real meanings, and it is in fact one of the aims of discourse to show how language is working and what c ontext it is being used in. .. Using a language involves something that goes beyond the acquisition of structures and the ability to make appropriate choices in the realization of the particular language functions. † (Yalden, 1987, p 39). Every language finds its ways in discourse and in order to understand a speech or a text it so very necessary to get into the depth of that very spoken or written text and go for the context of it. Because unless the text is seen as having more than surface meanings, it would not be easy to get real meaning and understand the motive and intention of speaker.Discourse always intends to bring forth the context of a thing and bring into light which is otherwise not transparent enough to a reader and listener. Because it’s so very evident that our words have never been neutral and language is not an abstract thing rather our words have meanings and they belong to some particular social and political condition. It’s quite important t o know that what actually people do with words and this takes language from being comprised of structures and grammar to function and communicative competence. 2. Discourse AnalysisDiscourse analysis is a rapidly growing and vast field. Discourse explains that how texts relate to contexts of situation and context of culture. How texts are produced as a social practice, what texts tell us about happenings and what people think and belief. Text analysis is the study of formal linguistic devices that distinguish a text from random sentences. Discourse analysis takes into account the text-forming devices with reference to the functions for which the discourse was produced, and the context within which the discourse was created.The very aim of discourse analysis is to show how the linguistic elements help language users communicate. Cohesive devices tell us the text and discourse is the meaning in the context. When we find out meaning in the context, and when we find out meaning from a t ext that will become discourse, and when analyze the text along with the context it becomes discourse analysis. It’s a well known fact that language is checked not in the text but in context as well. It is very necessary to know historical background of any event.For example if a text consists of words about 9/11, it will be obvious to for the historical story. To know actually about a text background knowledge is required which will make the sense even more clear. Certain structures are traced out to reach to the meanings and this is called discourse analysis. Discourse analysis is a methodology but a research as well. It brings new things into knowledge and refers to expressing oneself using words. It is evident that words are never neutral and everything which is written or read has some meanings and through discourse analysis those meanings become clear.This is discourse analysis which enables the analyzer from seeing language as abstract to seeing it as having some meani ngs related to particular conditions like historical, social or political. Discourse analysis has been used to describe a number of research approaches whose ultimate purpose is to focus on the use of language. Conversational analysis, critical discourse analysis is some kinds of discourses which have their own methods and assumptions but the ultimate purpose is to explain the way meanings are constructed in communication.A wide range of texts including journals and broadcast media, political speeches, interviews have been understood through the application of discourse analysis. Discourse analysis includes the ways in which people assume meanings of a text within a given context. Conversational analysis focuses on the analysis of the ways language is being used. It tells how people respond to any conversation and how they make use of a specific word or any provided phrase. On the other hand critical discourse analysis (CDA) is concerned with the imbalance sources of power, inequali ty and bias. 3. Critical Discourse AnalysisThe term critical discourse analysis is an approach which studies discourse in which language is viewed as a form of social practice and focuses on the ways social or political domination are presented by text and talk as well. Power is one of the concepts CDA deals with and CDA tends to analyze the language of those in power, of those who are responsible for the inequalities in done in a society. Moreover CDA researchers attempt to know how discourse produces domination, and how power abuse of one group is exercised on others. And how dominated groups may strive to resist such actions. Critical Discourse Analysis (CDA) is a type of discourse analytical research that primarily studies the way social power abuse, dominance, and inequality are enacted, reproduced and resisted by text and talk in the social and political context. † (van Dijk, 2001, p. 352) One more important perspective concerned by CDA about â€Å"power† is that it is a very rare chance that a text is a work of only one individual. There exists in texts certain evidence which, if observed through a critical eye, clearly shows the ideologies of those who intend to struggle for dominance.The constant unity of language with a number of social issues makes one thing clear and obvious that there is a close relationship of language with social power and this relationship occurs in a number of ways. Power is not essentially derived from language but language can be used in a way so as to challenge power. Language enables to establish differences in power in hierarchical social matters, issues and structures. The actions and words of those in power are always considered of great significance and given a particular importance.And they apply different strategies which are more than enough to show their interests, and it so happens that their words are taken as the ultimate truth. â€Å"The words of those in power are taken as â€Å"self-evident tru ths† and the words of those not in power are dismissed as irrelevant, inappropriate, or without substance† (van Dijk, 2000). In fact it is one of the responsibilities of the CDA researchers to play a very important role in bringing into light the problems and issues of those who have become the victims of dominance and power abuse, and then question the voice of those who have been exercising their power over other groups.Indeed it’s so very important to question them in order to reveal their hidden motives, their superiority, personal interests to make others subjugated. â€Å"†¦ home practitioners must engage in critical discourse analysis to make the voice of the marginalized legitimate and heard and to take the voice of those in power into question to reveal hidden agendas and motives that serve self-interests, maintain superiority, and ensure others’ subjugation. (Henry & Tator, 2002) As already mentioned that CDA’s main concern is about t he power and use of power which is reflected in the text and talk of those who struggle to maintain their authority over others, so it is believed that oppression, inequality and biasness would be left unchallenged if the text is not viewed and analyzed keenly and critically. â€Å"Given the power of the written and spoken word, CDA is necessary for describing, interpreting, analyzing, and critiquing social life reflected in text† (Luke, 1997). Power, dominance and inequality are equally interpreted by the help of CDA as these terms are major concern of CDA. CDA is concerned with studying and analyzing written texts and spoken words to reveal the discursive sources of power, dominance, inequality, and bias and how these sources are initiated, maintained, reproduced, and transformed within specific social, economic, political, and historical contexts† (van Dijk, 1988). As a matter of fact CDA aims to bring a reform in the society and tries to illuminate the paths of supp ressed groups and people. Its whole purpose is to let the oppressed groups know of the injustice done to them and make them able to resist it in order to make their lives worth living.It is in fact a path which tends to lead the dominated bodies to transform their lives. CDA has got many objectives and one of those is to uncover the ideologies that are otherwise hidden in the words or written texts. â€Å"†¦ a critical approach to discourse seeks to link the text (micro level) with the underlying power structures in society (macro sociocultural practice level) through discursive practices upon which the text was drawn (meso level)† (Thompson, 2002). Language tends to have some meaning in it which is not transparent always.CDA plays an important role in making those meanings clear which are otherwise opaque to a common man. â€Å"CDA helps make clear the connections between the use of language and the exercise of power (Thompson, 2002). † CDA does also aim to find connection between social power and discourse. According to van Dijk (1996), â€Å"one of the central tasks of CDA is to account for the relationships between discourse and social power† (p. 84). CDA actually makes itself involved in many social issues which need to be resolved. They can be political issues, power abuse and many others. CDA sees itself as politically involved research† (Titscher et al, 2000, p. 147). Now it will be clear that CDA is interested in analyzing and critiquing the obvious as well as hidden structural relationships of discrimination, inequality, power, dominance and control which are shown by language use. 4. Application of CDA This research study is concerned with the critical analysis of speech of the president of America telling the entire world about the death of Osama Bin Laden (Leader of Al-Qaeda) who was shot dead in his apartment, in Abbotabad (Pakistan), after an operation by the USA troops.Researchers would be interested in criticall y analyzing the whole speech/text in order to find out traces of power imbalance, inequality, and unjustified practice made by the USA. This research will also take into consideration the views of some of the officials of American government as well as the remarks made by Prime Minister of Pakistan. The agendas, ideologies, and hidden motives of the dominant group, in this case America, would be brought into consideration through the help of critical discourse analysis of the speech by President Obama.It will be viewed that how they have managed to show their dominance over others (Pakistan) and what kind of imbalance of power relationship has been generated by the dominating country (USA). 5. Background of Osama bin Laden Al-Qaida leader Osama Bin Laden is believed to have ordered the attacks on New York and Washington on 11 September 2001 and a number of others. He was top of the US most wanted list. And then a war had been declared against Al-Qaida by the USA.And this operation i n Pakistan was done when the American government was sure enough about Bin Laden’s presence in Pakistan. 6. Text of President Obama Speech THE PRESIDENT: Good evening. Tonight, I can report to the American people and to the world that the United States has conducted an operation that killed Osama bin Laden, the leader of al Qaeda, and a terrorist who's responsible for the murder of thousands of innocent men, women, and children. It was nearly 10 years ago that a bright September day was darkened by the worst attack on the American people in our history.The images of 9/11 are seared into our national memory — hijacked planes cutting through a cloudless September sky; the Twin Towers collapsing to the ground; black smoke billowing up from the Pentagon; the wreckage of Flight 93 in Shanksville, Pennsylvania, where the actions of heroic citizens saved even more heartbreak and destruction. And yet we know that the worst images are those that were unseen to the world. The em pty seat at the dinner table. Children who were forced to grow up without their mother or their father.Parents who would never know the feeling of their child's embrace. Nearly 3,000 citizens taken from us, leaving a gaping hole in our hearts. On September 11, 2001, in our time of grief, the American people came together. We offered our neighbors a hand, and we offered the wounded our blood. We reaffirmed our ties to each other, and our love of community and country. On that day, no matter where we came from, what God we prayed to, or what race or ethnicity we were, we were united as one American family. We were also united in our esolve to protect our nation and to bring those who committed this vicious attack to justice. We quickly learned that the 9/11 attacks were carried out by al Qaeda — an organization headed by Osama bin Laden, which had openly declared war on the United States and was committed to killing innocents in our country and around the globe. And so we went to war against al Qaeda to protect our citizens, our friends, and our allies. Over the last 10 years, thanks to the tireless and heroic work of our military and our counterterrorism professionals, we've made great strides in that effort.We've disrupted terrorist attacks and strengthened our homeland defense. In Afghanistan, we removed the Taliban government, which had given bin Laden and al Qaeda safe haven and support. And around the globe, we worked with our friends and allies to capture or kill scores of al Qaeda terrorists, including several who were a part of the 9/11 plot. Yet Osama bin Laden avoided capture and escaped across the Afghan border into Pakistan. Meanwhile, al Qaeda continued to operate from along that border and operate through its affiliates across the world.And so shortly after taking office, I directed Leon Panetta, the director of the CIA, to make the killing or capture of bin Laden the top priority of our war against al Qaeda, even as we continued our broade r efforts to disrupt, dismantle, and defeat his network. Then, last August, after years of painstaking work by our intelligence community, I was briefed on a possible lead to bin Laden. It was far from certain, and it took many months to run this thread to ground.I met repeatedly with my national security team as we developed more information about the possibility that we had located bin Laden hiding within a compound deep inside of Pakistan. And finally, last week, I determined that we had enough intelligence to take action, and authorized an operation to get Osama bin Laden and bring him to justice. Today, at my direction, the United States launched a targeted operation against that compound in Abbottabad, Pakistan. A small team of Americans carried out the operation with extraordinary courage and capability. No Americans were harmed.They took care to avoid civilian casualties. After a firefight, they killed Osama bin Laden and took custody of his body. For over two decades, bin L aden has been al Qaeda's leader and symbol, and has continued to plot attacks against our country and our friends and allies. The death of bin Laden marks the most significant achievement to date in our nation's effort to defeat al Qaeda. Yet his death does not mark the end of our effort. There's no doubt that al Qaeda will continue to pursue attacks against us. We must — and we will — remain vigilant at home and abroad.As we do, we must also reaffirm that the United States is not — and never will be — at war with Islam. I've made clear, just as President Bush did shortly after 9/11 that our war is not against Islam. Bin Laden was not a Muslim leader; he was a mass murderer of Muslims. Indeed, al Qaeda has slaughtered scores of Muslims in many countries, including our own. So his demise should be welcomed by all who believe in peace and human dignity. Over the years, I've repeatedly made clear that we would take action within Pakistan if we knew where bin Laden was. That is what we've done.But it's important to note that our counterterrorism cooperation with Pakistan helped lead us to bin Laden and the compound where he was hiding. Indeed, bin Laden had declared war against Pakistan as well, and ordered attacks against the Pakistani people. Tonight, I called President Zardari, and my team has also spoken with their Pakistani counterparts. They agree that this is a good and historic day for both of our nations. And going forward, it is essential that Pakistan continue to join us in the fight against al Qaeda and its affiliates. The American people did not choose this fight.It came to our shores, and started with the senseless slaughter of our citizens. After nearly 10 years of service, struggle, and sacrifice, we know well the costs of war. These efforts weigh on me every time I, as Commander-in-Chief, have to sign a letter to a family that has lost a loved one, or look into the eyes of a service member who's been gravely wounded. So Americans understand the costs of war. Yet as a country, we will never tolerate our security being threatened, nor stand idly by when our people have been killed. We will be relentless in defense of our citizens and our friends and allies.We will be true to the values that make us who we are. And on nights like this one, we can say to those families who have lost loved ones to al Qaeda's terror: Justice has been done. Tonight, we give thanks to the countless intelligence and counterterrorism professionals who've worked tirelessly to achieve this outcome. The American people do not see their work, nor know their names. But tonight, they feel the satisfaction of their work and the result of their pursuit of justice. We give thanks for the men who carried out this operation, for they exemplify the professionalism, patriotism, and nparalleled courage of those who serve our country. And they are part of a generation that has borne the heaviest share of the burden since that September da y. Finally, let me say to the families who lost loved ones on 9/11 that we have never forgotten your loss, nor wavered in our commitment to see that we do whatever it takes to prevent another attack on our shores. And tonight, let us think back to the sense of unity that prevailed on 9/11. I know that it has, at times, frayed. Yet today's achievement is a testament to the greatness of our country and the determination of the American people.The cause of securing our country is not complete. But tonight, we are once again reminded that America can do whatever we set our mind to. That is the story of our history, whether it's the pursuit of prosperity for our people, or the struggle for equality for all our citizens; our commitment to stand up for our values abroad, and our sacrifices to make the world a safer place. Let us remember that we can do these things not just because of wealth or power, but because of who we are: one nation, under God, indivisible, with liberty and justice f or all. Thank you. May God bless you.And may God bless the United States of America. 8. Analysis The speech opens with a detail explanation of the whole incident of Abbotabad (Pakistan) and President Obama congratulates the people of his country and the rest of the world about the victory which embraced them after a long span of time. Then there are a few statements about what did the families of the victims of 9/11 go through and what kind of grief surrounded the whole nation. But there then comes some statements which, if analyzed critically, clearly show the efforts America has made to fulfill her personal interests.Obama at one instant states, â€Å"Over the last 10 years, thanks to the tireless and heroic work of our military and our counterterrorism professionals, we’ve made great strides in that effort. † And then he makes further comments which are a clear cut example of their intent to show dominance over Al-Qaeda and then their efforts to fulfill their own se lf-interests. Says he, â€Å" And around the globe, we worked with our friends and allies to capture or kill scores of al Qaeda terrorists, including several who were a part of 9/11 plot. These two above mentioned fragments of his speech just seem enough to elaborate their point of view about their position in the world and their way of doing things. It is obvious that they have been putting themselves in this effort for last ten years. Then the point becomes even clearer when President Obama talks about the result of their continuous efforts and tell the world how they located bin Laden. â€Å"Then, last August, after years of painstaking work by our intelligence community, I was briefed on a possible lead to bin Laden.It was far from certain, and it took many months to run this thread to ground. I met repeatedly with my national security team as we developed more information about the possibility that we had located bin Laden hiding within a compound deep inside of Pakistan†. This statement if observed superficially will only be discussing about the fruitful results of the US intelligence on the matter of bin Laden’s capture. But in the eyes of CDA it’s just not a simple statement but it is something greatly related with the imbalance power relationship with Pakistan as well.If analyzed and interpreted critically, it becomes obvious that USA government has shown little reluctance in sharing their plans with Pakistan. For example to understand it more clearly just ponder on the words said by Obama. â€Å"I met repeatedly with my national security team as we developed more information about the possibility that we had located bin Laden hiding within a compound deep inside of Pakistan. † What does â€Å"my national security team† mean? It obviously means that Obama has just asked his national security team to go through the process of finding Laden.He has not mentioned that any plan or idea is shared with Pakistani officials or intelligence. So through the application of CDA and considering its main purpose it is evident that nothing matters for them as far as their interests are concerned. Pakistani security team was just not told anything and USA just took their special team in confidence. It means that they have been struggling and making many efforts without letting Pakistan know anything about it.And it must be observed that the process of inquiring about Laden’s presence was taking in Pakistan and Obama makes it clear in his speech that he learned that Laden was present â€Å"deep inside of Pakistan†. Now this is again something of great importance, as it is like showing dominance and power over other country. In the above stated comment of Obama two things show the excessive use of their power. First President’s meeting with his security team only and second the action of investigating Laden’s presence in Pakistan is the thing not being shared with the country where he actual action was to take place. This is to be considered as one of the examples of inequality and wrong use of power by USA. The story is just not over here as there comes many more evidence in the text which represent the inequality USA seems have done to Pakistan. â€Å"Today, at my direction, the United States launched a targeted operation against that compound in Abbotabad, Pakistan. † There again needs to apply CDA and get into the depth of the statement and reach to the real meanings which are otherwise hidden and not easily understandable. Today, at my direction† is just not simple phrase but something that is more than enough to affect the power relationship between two independent countries. â€Å"Today† seems to specify the day and time which appeared suitable to the dominating country and then â€Å"at my direction† is indicating towards something which goes in favor of USA because here again it is noticeable that President Obama looks like in believing in his own orders and directions, not giving any clue of the direction or requirement of taking the direction of Pakistani government.This if critically analyzed is pointing towards the belief which the USA government might have in them and in their power as well. And this looks like USA tends to imbalance the power relation with Pakistan and makes that country dominated by such remarks and action as well. Then there come another statement which looks even closer to the way one may exercise their power over other group or a country might be. â€Å"Yet his death does not mark the end of our effort. There’s no doubt that al Qaeda will continue to pursue attacks against us.We must—and we will—remain vigilant at home and abroad. † In the above mentioned statement there are three important words which are enough to grab the attention of those who work through CDA. â€Å"We must, we will remain vigilant at home and abroad are not having ordinary mea nings in them as it is well known fact that words are not always ought to be neutral. If viewed deeply there in that statement a word is used â€Å"abroad† and it seems to indicate some determination of American government.Using words like â€Å"we must†, â€Å"we will† is a way adopted for asserting their power and dominance. And it’s not their country only they will be working but abroad as well. And abroad can be any other country or Pakistan may be as he didn’t mention it at all. , as he said it was not the end of their efforts and any further action could be possible in future. Judging this very fragment of his speech it might be said that it was not at all a neutral statement and contained in it a signal to show their strength and then will to exercise power whenever they feel it to exercise. Over the years, I’ve repeatedly made clear that we would take action within Pakistan if we knew where bin Laden was. That is what we’ve do ne. † Such a statement from president of USA for another independent country is indeed of great attention as it again refers to the same thing which CDA aims at. Critically evaluating, this statement contains some meaning which seems to give world an idea about what USA thinks and wants to do. To make an argument like â€Å"I’ve repeatedly made clear† is containing a huge meaning in itself.It refers to the idea of being always right, and dominant. And if analyzed this statement more deeply, it appears as if America is biased toward Pakistan and this is shown through the text itself. â€Å"†¦. that we would take action within Pakistan if we knew where bin Laden was. † This remark is showing the bias America is or may have against Pakistan. As it shows that they are already having some prejudice against Pakistan and have repeatedly made it clear that they would take an action if found it good in their interest.Continuing further he adds that he called P resident Zardari and his officials and was told that it was a great day for both of their nations and further Obama states, â€Å"And going forward, it is essential that Pakistan continue to join us in the fight against al Qaeda and its affiliates. † It does seem opaque that what kind of contribution they are asking Pakistan to make, they may be signaling toward the same way they just adopted to attack Osama in Pakistan, and making Pakistani government clear that their contribution lies in the fact that they would not be asked if the action is to be taken again to attack any other member of al Qaeda.President Obama’s speech consists of many fragments in which he every now and then shows his sympathy with his nation about the incident of 9/11 and ensures to take possible measures to protect their country but that statement itself becomes controversial and looks like to serve their purposes only. Says he, â€Å"Yet as a country, we will never tolerate our security being threatened, nor stand idly by when our people have been killed. We will be relentless in defense of our citizens and our friends and allies,† This statement is just telling the way they want to secure their country.And letting the entire world know of what they think of the security of their people and country. But in a way or other it suggests that it is only their security that matters and they will not allow anyone to threaten their security, moreover they will be relentless in defense of their citizens. But the question arises that what about the security of the country which was threatened and weakened when President Obama took that action in Pakistan and made it clear that they had already said that any action of this sort could take place in Pakistan if necessary.On one side securing their own country and on the other hand not showing any concern about the security of the other country (Pakistan). These kinds of phrases are interpreted with the help of CDA in order to detect the hidden ideologies of the dominating country. And statements like this and many others are a warning to let others know not to take this matter lightly. CDA aims at exploring the motives of dominant group and it tells what one is allowed and expected to do. President Obama concludes the speech with a statement which contains in it a message which confirms their dominance, power and threat to power relation with Pakistan.Adds he further, â€Å"The cause of securing our country is not complete. But tonight, we are once again reminded that America can do whatever we set our mind to. That is the story of our history, whether it’s the pursuit of prosperity for our people, or the struggle for equality for all citizens; our commitments to stand up for our values abroad, and our sacrifices to make the world a safer place. † Though these are the closing comments from president Obama but they do have the signs of over dominance. â€Å"†¦America can do whatever we set our mind to. If this and many other above mentioned statements are left unchallenged then power relation and excessive use of dominance by America in this particular case can create many problems for the country who is being repressed and dominated. As it is one of the main aims of CDA to reveal hidden motives which do lie in texts and words, this piece of text does need a critical analysis. Telling what America can do somehow discloses the ideological assumption of America. This appears like America has got some firm belief in their strength and that they can do whatever they want to do.It’s through the application of CDA that it becomes possible to let others know that how those who in power maintain their superiority and how they want or ensure others subjugation. This statement is just no looks like a warning to al Qaeda only but to the entire world. Saying that America can do anything seems like America can attack Al Qaeda again as well as America can make use of it s excessive power by maintaining its dominance and can again take such sort of action in Pakistan. It points towards the commitment America has made in order to be superior and ensure its superiority over others.CDA is very helpful in such situations as it help in understanding that how one exercises their authority through words. This very statement is a signal toward the presence of imbalance in power relationship between the two countries (Pakistan and America). And CDA helps understand the social problems, inequality and excessive use of one’s power and superiority over others. Some comments of the American officials have also been added and analyzed with the help of CDA. BBC reports on May 2, 2011. The US official said that intelligence had been tracking a trusted courier of bin Laden for many years.The courier’s identity was discovered four year ago, his area of operation two years ago and then, last August, his residence in Abbotabad was found, triggering the st art of the mission. (BBC News) This news by US official reflects the same idea as it was there in President Obama’s speech. Their continuous effort to find out Osama’s residence across the world appears to be their top priorities. And as the official said that at last they found him in Abbotabad (Pakistan), it looks like that they had kept an eye on Pakistan.But what happened actually that the plan was not at all shared with Pakistan, which seems like a way used by US to exercise its superiority and keep its self interest most important. It actually can be fatal for the power relation between the two countries because inequality can be seen in this very case. According to another report by BBC it was said that nothing about the plan was shared with anyone including Pakistan. The official said â€Å"Only a very small group of people inside our own government know of this operation in advance. (BBC News) The statement is what CDA aims to bring into notice. US officials knew that the operation was to be held in Pakistan but it was not their concern to share it with the officials of Pakistan. At surface level this statement is not that dangerous but its critical analysis may make it prominent and questionable. The information was shared with a very few people of the US and it indicates towards the inequality shown by the US. It too shows the power abuse which according to CDA needs to be resisted.Power relations can be at risk if such statements are made by an independent country for another independent country. It looks like as if sovereignty of a country has been challenged through the words of those who have power and this time Pakistan seems to be the victim of such oppression and injustice. The nature of these remarks makes CDA an interesting task. This should be kept in mind that those who are in power they keep asserting their dominance through the use of words and this has just been shown and understood through the critical discourse analysi s of above mentioned remarks of the US officials.BBC News had too added the remarks of different officials of many countries but in this very analysis the remark of Prime Minister Yusuf Raza Gilani would be analyzed. â€Å"Pakistan Prime Minister Yusuf Raza Gilani said the killing was a â€Å"great victory† but added that he â€Å"didn’t know the details† of the US operation. † (BBC News) CDA aims to highlight oppression, repression and marginalization by critically analyzing the text to reveal dominance. And what makes the remark of Prime Minister a questioning one. The declaration of Mr.Gilani about having no details about the US operation seems to ensure what America wanted for them. The operation was made in Pakistan and the Prime Minister of the same country has not been told about it. Dominance of America may be observed here as there comes no resistance from the words of Prime Minister. Moreover it seems to ensure the subjugation of Pakistan and do mination of America in the very incident of Abbotabad. This is an attempt to critically analyze the words of those in power. It is shown that what it looks like and what it actually is. . Conclusion Let this fact be acknowledged that those in power have always some hidden motives and ideologies which they adopt to serve their purposes and fulfill their self-interests. Their words are not at all neutral rather they have respective hidden agendas which they use to maintain their superiority. The same has been understood by critically analyzing the text of President Obama’s speech after the death of bin Laden. CDA tries to illuminate ways followed by dominant forces that favor their personal interests.A text may appear flat if not critically observed but if critically evaluated it reveals hidden traits of those who tend to exercise their power by using words and speech. CDA has played a major role in unraveling the text and meanings which are contained in it.

DISCLAIMER: The text of Obama’s speech was taken for the research purposes only and none other purpose should be extracted out of this analysis.The text analysis should not be taken politically or personally.
