3 Artworks of 3 Artist releating to speak and memory - Assignment Example The concept of memory and speak is brought in the painting Kahlo’s Self-Portrait with Portrait of Dr. Farill as it depicts her state of psychology during her long, tempestuous relationship with Diego Rivera (Lindauer 83). Even when her partner Rivera figure does not appear in her painting, she has a tendency to identify other elements and features of her paintings as a symbol of the presence of her partner. To make herself well remembered, she paints herself having heavy eyebrows that are joined into one in order to express and androgynous mind. It is striking how Dr. Farill, who had normal eyebrows, gains unified ones in the painting. She wants to be associated with her physician and to hold the memories of him when she alters her costume to resemble a white coat of a physician. Her diary confirms her need to keep the memory of the doctor, and her identification with the doctor in the portrait is to show as her the doctor works hard, continues to care for the sick while he is also seriously ill (Lindauer 87). Kahlo wants to depict the importance of doctors in the society and why they should be remembered. The brushes and a palette just close to her painting of her doctor that depicts the nature of Kahlo’s art, where she says that her painting is carrying a message of pain. The palette in her lap is replaced by part of her heart, while her paintbrushes are dripping with blood, that leaves the view with no doubt that her existence is important and need a memory. When one looks at this painting and identifies the different elements used, one cannot help but see the artwork of Jan Van Eyck. Here the concept of memory is brought up as Durer does not the painting of Eyck to go unremembered, but is in memory of those who view his own paintings. Durer puts an inscription some place within his painting so that he can bring to the viewer the meaning behind the painting (Koerner 31). It is his signature of using inscription

Law Enforcement Function - Assignment Example There are several steps towards approaching this model, and the number decreases at each step due to weakening. This model is crucial as it has been known to prevent the overcrowding of the criminal justice. This has an influence on the police department because the criminal justice starts with the crime being committed and a careful follow up on the crime is done (Reichel, 2002). Therefore, the fact that it prevents the overcrowding of the criminal justice shows that the number of trials decline and the overall number of people imprisoned reduces significantly. This has proved to save man hours, as well as money. The wedding cake model is an illustration on how different cases are grouped in a sequential manner according to their sensitivity, with the less sensitive case at the bottom and the more sensitive at the top. In a police department, the wedding has some influence as it follows the different layers; to know the stand of the judiciary (Reichel, 2002).The most sensitive cases attract different reactions from the public, which may give incorrect information about the criminal justice process. During the processing of the case, this model ensures that each layer is handled according to each individual and that similar cases are treated systematically, which is very helpful in a police department (Reichel, 2002). The third model is the net model, which is an illustration on why some cases never proceed to the court of law. In this model, a clear illustration is given on why some offenders are allowed to exit while others struggle only to find themselves entrapped, and this is important in the police department (Reichel, 2002). The structure and procedure of a police department differ from crime control model to due process models as illustrated hereunder. The purpose of the crime control department is to prevent department by all means by considering the safety of an individual over the right of

Political films Essay Example for Free

Political films Essay The research paper â€Å"The Timing of Presidential Cinema† discusses and analyzes social meaning of political films. Little research is done in this filed, although many films contain political and economic meaning. Interestingly, the release of presidential cinema is associated with the controlling party and with the ideology that the party has in the White House. Republican and Democratic administrations are characterized by the largest amount of political films. Moreover, more films are released during the second presidential term. Releases are more acute during presidential elections. The stronger the economies, the more films about presidents are released. The article â€Å"Quantitative analysis of Motion Picture Content† tends to measure the influence of films on American population. In particular, the emphasis is paid to providing an instrument to measure with scientific precision the content of each film. The cinema has long been accepted and the author argues that more than fifty million of American moviegoers are influenced by desire to seek entertainment when going to the cinema. Therefore, motion picture has become a profound influence on people and it is rather difficult to measure those influence. The role of Hollywood films in American society has not been yet questioned as researchers lack methods to summarize and analyze what the public is presented. The article â€Å"The Image of the Scientist in Science Fiction: A Content Analysis† reviews the social role of the scientists which is conveyed through the cinema. Scientists has undergone both criticism and appraisal, they has been presented as heroes and villains science-fiction magazines, stories and films. Of course, many scientists have been negligible. The social role of the scientist is addressed in terms of saving humanity, but after World War II such measurement has become problematic. Science fiction, therefore, is claimed to serve as vehicle to construct social utopias and to dethrone them. The article is of practical relevance as the USA experience shortage of scientists and engineers.

Effect of PRF After Mandibular Third Molar Surgery

Effect of PRF After Mandibular Third Molar Surgery Post extraction wound healing and physiologic sequelae of third molar surgery can significantly affect the patient’s quality of life2. Various methods have been suggested to improve extraction socket healing and to minimize the postoperative sequelae after third molar surgery4,5. PRF is a second-generation platelet concentrate which is known to stimulate wound healing by releasing growth factors directly to the wound5,8,16,17. Recent studies demonstrated the PRF membrane has a very significant slow sustained release of key growth factors for at least 7 and up to 28 day13. Studies on PRF efficacy in enhancing wound healing have yielded differing results and also there is a divergence of opinion on the activity of PRF. Thus, there is the need for more studies to explore its use in oral and maxillofacial surgery. This study was therefore perceived to determine the effect, if any, that PRF has on postoperative sequelae and enhancement of bone healing after mandibular third molar s urgery. Patients and Methods The study sample consisted of 15 young adult volunteers 18 to 22 years old presenting with impacted mandibular third molars bilaterally and in similar positions. Patients using systemic drugs or presenting a medical history positive for any systemic pathology or a history of hypersensitivity to any component used in the methodology were not included. Each patient participated as a volunteer after signing an informed consent form on the study for extraction of impacted right and left mandibular third molars. Ethical clearance was obtained from the Ethics Committee prior to the commencement of the study. The following demographic information was collected: age, gender, occupation, marital status, and educational level. Furthermore, the position and type of impaction were recorded. The two operated sides in each patient were randomly divided into 2 study groups: extraction of an impacted mandibular third molar at first side whose socket was filled with blood clot and wound sutured (cont rol group), and extraction of an impacted mandibular third molar on the other side whose socket was filled with PRF gel and wound sutured (PRF group). A 10-point visual analog scale (VAS) with a score of 0 equals â€Å"no pain† and ten equals â€Å"very severe pain† was used to assess pain. Facial swelling was evaluated using a modification of the method described by Schultze-Mosgau et al9, and this entailed measuring the distances from the tragus to the oral commissure and tragus to the pogonion. The arithmetic sum of the two measurements was used to determine the facial swelling at the time point. The percentage facial swelling was calculated from the difference of the measurements made in the preoperative and postoperative periods divided by the value obtained in the preoperative period and multiplied by 100. (Swelling Postoperatively–Swelling Preoperatively) /Swelling Preoperatively X 100 Digital radiographs were used to evaluate changes in radiographic bone density for each extraction site. Three blinded dental professionals working independently evaluated all radiographs. RVG software was used for radiographic analysis. Radiographs were evaluated by three blinded dental professionals. The radiographs were assessed by obtaining the average density of three independent readings of the 3rd molar extraction socket sites. This was compared to the average of three density outlines of the adjacent tooth. When all radiographs for a patient were assessed, they were normalized to the original radiograph and the same untouched adjacent tooth. The baseline socket average was then subtracted from the normalized average for each tooth extraction socket at the different time points. The final, normalized socket value differences for each PRF-treated and non-PRF treated site for the various time points were compared. All radiographs were taken by a blinded, certified x-ray dental assistant. They were taken immediately post-operatively and at the following time after the day of surgery: 4th week, 8thweek and 12thweeks. Preparation of Platelet-Rich Fibrin PRF was prepared according to the technique described by Choukroun et al1. Twenty minutes before starting surgery, 10 mL of venous blood was collected in a sterilized dry, neutral glass tube without an anticoagulant. After immediate centrifugation at 3000 rpm for 10 minutes, the platelet-poor plasma, which accumulated at the top, was discarded. PRF was removed approximately 2 mm below its connection to the red corpuscle beneath to include remaining platelets, which have been proposed to localize below the junction between PRF and the red corpuscle After 10 minutes, the gel was formed, and autologous PRF was applied immediately in the socket in the PRF group. Surgical Procedure- To standardize the surgical operations, all patients were operated by the same surgeon. The mandibular third molars of which the extraction sockets would receive PRF treatment were selected randomly before surgery and these molars were operated on first. After tooth extraction, the surgical area in the PRF group was isolated with gauze and the socket was filled with PRF gel. In the control group, the socket was not filled with PRF. The flap was repositioned by an interrupted suture with 3-0 silk suture. The patients received oral and written postoperative guidance, and follow-up was scheduled according to the study periods. Because only the bilateral mandibular third molars similarly impacted were selected for the study, there was no significant difference in the time and surgical trauma associated with surgical extractions. Immediately after the procedure, details of each procedure were recorded, including the duration of surgery in minutes (from the first incision to insertion of the last suture), and any intraoperative complications. Patients were then recalled at 1, 3, 7, and 14-day postoperative intervals. During such visits, data were recorded for postoperative pain,facial swelling and any untoward complications like infection and alveolar osteitis. Sutures were removed 7 days after surgical operation. Patients were also recalled at the 4th, 8th, and 12th week postoperatively for radiographic bone healing assessment. Results The mean age of the sample population was 21.40(range 18 to 35 years). There was no statistically significant difference in the age, gender, and type of impaction between both groups. In both groups, the mean postoperative pain score (VAS) was highest at postoperative day 1 and gradually reduced over the following 14 days. The mean postoperative pain score (VAS) was higher for PRF group than control group at all-time points when compared with the control group and was not statistically significant (P The percentage facial swelling for the PRF group relative to baseline value was 2.55%, 2.22%, and 0.28% on postoperative days 1, 3, and 7 respectively, whereas it was 1.86%, 1.5%, and 0.29%, respectively, in the non- PRF(control) group for the same period. The percentage facial swelling was highest at postoperative day 1 and gradually reduced over the following days for both groups. The mean percentage swelling was also higher for the PRP group at all-time points when compared with the control. However this difference also was found to be not statistically significant. The mean bone density score was higher in the PRF group than the non-PRP group over a 12-week period; and the differences were found to be statistically significant. The results of the present study clearly show that the application of autologous PRF in surgical wounds after tooth extraction allows acceleration of bone healing, as indicated by data with statistical differences (p DISCUSSION This prospective study evaluated the performance of PRF gel when applied to fresh extraction sites. Third molar extractions are often used as a measurement tool for comparing treatments because they are usually performed electively on a younger population that do not present with significant medical problems (e.g., systemic pathologies, multiple medications). Therefore, this study is especially relevant for healthy 18 to 40 year old patients. This study evaluated the effect of PRF gel on postoperative pain, swelling and bone regeneration potential on third molar extraction sockets. The mean postoperative pain score (VAS) and swelling were higher for the PRF group at all-time points as compared with the control group, but the differences obtained were found to be statistically non-significant. This suggests that topical application of PRF may not improve the postoperative sequelae after third molar surgery. Choukroun et al5 in a case report found reduced pain and better mouth opening when topical PRF gel was used in molar extraction sockets ,in contrast to this we observed increased pain and swelling when topical PRF gel was used in 3rd molar extraction socket . Intra-oral digital radiographs taken of the individual surgical sites revealed that the effects of PRF were significantly beneficial (P 6,similarly reported that the PRF induced complete bone filling of a residual cystic cavity in 2 months 2 weeks, a much shorter period than 6 to 12 months of physiologic healing. Choukroun et al7 in a case series on maxillary sinus lifting operations, 3 cases were treated with PRF and freeze-dried bone allograft mixture and 6 cases with freeze-dried bone allograft alone. Histomorphometric results of this study showed that PRF and allograft mixture accelerated bone regeneration, allowing implant placement in 4 months after maxillary sinus lifting procedure. Furthermore, the amount of newly formed bone was equivalent to that achieved with an allograft alone 8 months after surgery. Diss et al10 reported promising results after placing PRF instead of bone graft under the sinus membrane during a closed-sinus lifting technique and demonstrated that an ave rage of 3.2 mm bone gain could be obtained in the sinus after 1-year follow-up. However the results of our study does not correspond with the study from Gà ¼rbà ¼zer et al17 who reported scintigraphically, that platelet-rich fibrin might not bring about promoted activity of osteoblasts in impacted mandibular third molar sockets in 1 or 4 week after extraction. Accelerated bone formation observed is in contrast to the drop in bone density seen at the control site before bone formation began to take place. It took approximately 6 weeks for the control sites to reach the same bone density that the PRF-treated site had reached by 4 weeks. The PRF-induced acceleration in bone formation may be due to the presence of bone morphogenetic proteins (BMPs) in PRF that stimulates mesenchymal stem cells to begin osteoblast differentiation and subsequent calcification12,14,18. The immediate start of bone formation seen with PRF treatment is of clinical relevance because it is the initial 2 weeks following bone manipulation in oral surgery that are important in preventing infection, loss of the blood clot and/or dry socket formation. Digital panoramic radiographs might have been a better choice than digital periapical radiographs, as the 2 surgical sites would be represented on 1 film, eliminating the need for normalization between the sites. The disadvantage of digital panoramic radiographs is that these films have a 20 to 25% distortion factor because it is an extra-oral film, as opposed to the intra-oral individual (periapical) radiographs.The digital periapical radiograph was chosen over the panoramic radiograph due to the lower distortion, which results from being in close proximity to the site being evaluated. The CT scans might have exhibited greater differences between the PRF treated sites and the control sites, had they been obtained. Similarly Digital substraction radiography and histomorphometry have provided more sensitive methods of assessing bone healing but are quite invasive and expensive especially in a resource limited environment. Conclusion The results of the present study suggest that topical application of autologous PRF gel has a beneficial effect on the osseous healing of extraction sockets after third molar surgery but may not minimize the postoperative sequelae after 3rd molar surgery as its use was found to be associated with increased postoperative pain and swelling . However, a larger sample size in a multicenter study may be necessary before its routine use in extraction socket can be justified

Genetic Determinism Essay -- DNA Genetics Traits Essays Papers

Genetic Determinism On Christmas Day in the year 2001, I gave birth to a healthy baby boy. When I looked into the brand-new face of my son I saw a beautiful mystery. I wondered what kind of man my boy would grow to be and what his life would be like. There are those in the scientific community who would argue that my son's path was already determined at the moment of his birth, that his fate could be deciphered from his genetic make-up. As a nurturing mother I know better. At two years old my son has developed a more diverse vocabulary than many children twice or even three times his age. He recognizes many written words and reads them aloud. He is able to spell his name. He can distinguish a square from a rectangle and an octagon from a hexagon. Was he born with this knowledge? The answer is no. My son, as genetically gifted as he may be, could have been born into an environment in which his inborn potential was never developed. The knowledge he now possesses can be directly traced to the teaching envi ronment in which he has grown. Human beings are a product of both their biology and their environment. As a mother, I am shocked and dismayed by the general acceptance of the myth of genetic determinism. One's environment, including people one interacts with, has an undeniable influence on how one develops. Nonetheless, many scientists disregard the impact of environment on one's intelligence. I do not deny that one's biology is a crucial part of one's identity. Inheritance of physical traits is obvious. Children often look "just like" their father or mother, or another relative. One's genes determine eye and hair color, height and body build. I believe, however, that what makes us human is not something that can be found in... ...ork: Praeger Publishers, 1991.

Jerrocs Betrayal Essay example -- Star Trek Defector Essays Papers

Jerroc's Betrayal In the Star Trek: the Next Generation episode entitled "The Defector," an interesting issue concerning loyalty and credibility is raised. When Admiral Jerroc of the Romulan Empire turns himself over to the Federation in an apparent attempt to save both parties from a potentially catastrophic war, he violates most of the unstated rules of turning against one's comrades to fight for the enemy. His behavior and statements as a prisoner aboard the Enterprise cause Captain Picard to doubt Jerroc's explanation for why he has undertaken such a course of action. Jerroc's argument is fairly shaky, as he relies initially on ethos, trying to put forth his cause in the most straightforward manner. As time progresses and the situation grows more grave, however, Jerroc begins to utilize a more emotional argument, which is often very effective when conversing with the "good guys." Jerroc's method of convincing Picard that he is sincere plays heavily in attempting to analyze another aspect of the si tuation: whether or not Jerroc's betrayal of the Romulans constitutes a treasonous and seditious act against them, or if he is simply defecting to the cause in which he truly believes. Jerroc's inconsistent argument, combined with other circumstances which unfolded throughout the episode, is evidence that Jerroc has lost his faith in the Romulan cause and has done what he felt is right. These circumstances help to clarify Jerroc's reason for betraying his Romulan brothers and make the distinction between his being a traitor and his being a defector. Before attempting to place a label of defector or traitor on Jerroc, it is necessary to establish a working definition of the two terms. Both terms certainly constitute an act of ... ...s toward the Romulans. For this reason, Jerroc simply cannot be viewed as a traitor under the definition previously established. His behavior and motives clearly show that Jerroc's intentions were unbiased, and that he merely tried to do what was right. An important factor in trying to determine if Jerroc is a traitor or a defector is the perspective the opinion is taken from. Without a doubt, the Romulans would view him as a traitor, as it is certain that they feel many negative feelings toward him. Jerroc also damaged the Romulans in an indirect way by ruining a plan which may have benefited them greatly. The definitions must be applied in a neutral context, however, and that context clearly shows Jerroc's non-hostile attitude toward the Romulans. Ultimately, the inconsistencies in Jerroc's argument helped to establish him as a defector rather than a traitor.

Film Review: Boys Don’t Cry

Boys Don’t Cry is a movie examining the life of the late Teena Brandon. It is an intense movie that follows her journey to self-discovery and essentially her passing. Boys Don’t Cry not only explores how difficult it is to be queer but also what it means to have a sexual identity crisis (as Brandon puts it). Brandon goes through so much to cover his true identity and in the end nothing is enough. This adaptation of a true story engages and walks the watcher through the difficulties transgender people have in life.The opening scene of Boys Don’t Cry lets the audience know that Teena Brandon has now become Brandon Teena. Following the lines of New Queer Cinema this film gives the outside world a new way to look at transgender individuals. This film breaks new ground by showing â€Å"true crime material through the prism of New Queer Cinema† (Brooks, 2000) The fact that what happened to Brandon was true makes this movie all the more important. Both straights and queers can watch this movie in disgust and learn something from it also.Discrimination (any type and in this case especially sexual) should be stopped. Examining this movie more in depth the audience gets a look not only in the life of Brandon but of the people he surrounds himself with. In the Film Journal article Driving into the ‘Dustless Highway' of Queer Cinema By Daniel Mudie Cunningham he gives background information about Falls City, Nebraska. Being a native San Franciscan myself it helped to know what Falls City was all about because of the obvious contrast between California and Nebraska. Cunningham describes the â€Å"wall people† in his article.The â€Å"wall people† in Falls City are â€Å"bored kids who congregate against the wall at the Qwik Stop convenience store all night long. † This is actually a subculture in Falls City. The activities that Brandon and his friends do in the film are what actually happen there. Karaoke and whip-its a re the thing to do for fun in a place life Falls City. An interesting point that Cunningham brings up is that the lives the â€Å"wall people† live and essential the life Brandon wants to be in entraps them more to the rural un-open minded kind of life style.Brandon doesn’t see that moving from Lincoln to a more rural town like Falls City is a bad idea. I find it interesting that for the people in Falls City they probably would have done anything to get out of there but Brandon found refuge and called it his home. Even his love, Lana, wanted to get out of Falls City and go as far as Memphis. In actuality no one got to leave and if time could be turned back Brandon and Lana should have made their escape from the beginning. The reasons Brandon didn’t want to leave Falls City was because he thought that he had finally been accepted and he had found what he was looking for his whole life.Through out the movie we see Brandon searching for the perfect girl. His cousin , Lonnie, even says on the phone call back home from Falls City â€Å"no more girls† The romantic aspect of this film re-examines what romantic movies are really about. In this film Brandon is the apidemy of hot for a girl living in Nebraska. And even though Brandon has a secret no one cares because the way he talks and treats girls in interpreted as cute and loving so the lie doesn’t matter. When transforming from Teena to Brandon she/he chooses the sweetheart cowboy to be her male persona.With a cowboy hat and a little bit of a twang Brandon is able to sweep girls of their feet. Even with the first girl in the opening scene, Nicole, she points out that Brandon isn’t from around here and when asked where he is from she replies â€Å"somewhere beautiful. † Brandon’s boyish/girlish good looks and cowboy â€Å"I’m here to save you† charm wins everyone over. Enough so that his small physique and high voice gets left unnoticed. However no matter where Brandon would have went his identity could not be left behind.Brandon through out the whole movie was trying to be someone he wasn’t. Hiding his identity got him in all kinds of trouble. The reason he was found out was because of the petty crimes he committed trying to prove himself as a man. The beginning of Brandon’s undoing was when the gang and him were driving down the highway evading the police. Cunningham once again noted that this scene was an escape for Brandon but can also be seen as his downfall. Brandon’s life begins to swirl down the drain when little bits of is identity came out, from the ticket to the check written by Teena Brandon. As the events go by it is interesting that when Brandon finally gets some action form Lana she doesn’t freak out when she discovers he is a she. Brandon doesn’t exactly tell her but in the scene where they are first making love Lana sees Brandon’s cleavage. In the article written by X an Brooks for Sight and Sound Lana’s trust in Brandon is seen as commendable and endearing. To the very end Lana believed whatever Brandon believed and that was that he is a man.To bad for Brandon not all of his compadres were that trusting. The end of Boys Don’t Cry can definitely make one cry. The gut-wrenching finale is hard to take. When all is found out Brandon’s friends, especially John and Tom, turn against him and break him down in the worst way possible. The rape scene is crude and shows the destruction of Brandon’s life. Instantly he is turned back into Teena and is striped of all dignity and courage. All the characters worst personality traits prevail here except for Lana’s.Every one turns on Brandon including Lana’s mother who at one point was completely in love with him calling him a â€Å"movie star†. After the rape when Brandon was reporting it to the police the way the police treated him was horrible. The questions abo ut his sexuality were not pertinent to the rape and were said almost to humiliate him and insinuate that it was brought on because of his lie. A rape victim in Brandon’s case or in any other case has historically been led to believe that she brought it on herself for being sexy or for the clothes she wears.Movies like this can be used to open the doors to show the public how disgusting and unforgivable rape can be, especially when done out of the need for control by men. In the case of Brandon John and Tom had be threatened by Brandon’s cordial manner from the beginning. Brandon â€Å"who knew exactly how to please women, both carnally and emotionally† (Brooks, 2000) was more masculine in the way he treated women that when it was found out he was a she John and Tom finally found their chance to be superior and raped her. After rape death can be the worst thing to happen to a woman.After Brandon’s dignity was taken from him his life was also taken. After a beautiful scene when Lana and Brandon fully make love John and Tom find Brandon hiding out at Candice’s house and come for him. John purposefully takes Lana with them so she can witness the death of her lover. This ending scene is not typical however for a suspense movie. Brandon is killed instantly after some screaming and comes as a blunt shock to the audience. The death of Candice happens the same, very blunt and unexpected, with her child right beside her.Boys Don’t Cry was almost too much to absorb. Brandon’s intense death goes to show how closed-minded people can be. Brandon did nothing in his life but be the person he wanted to be and yet because that didn’t fit into the norm other people held he was murdered. The life and death of Brandon can be seen as a learning tool and a way to see how discrimination can only lead to bad things happening. Everyone should be left to their own devices and should be able to be whoever they want to be.
