The Personification of Death in Jean Cocteau’s Orpheus Essay

The Personification of Death in Jean Cocteau’s Orpheus The personification of Death is done by means of a princess of the Underworld in Jean Cocteau’s Orpheus. This Princess is very powerful, yet surprisingly vulnerable. For no one is allowed to love in the Underworld, the Princess falls in love with a famous poet named Orpheus and goes to drastic measures to be with him. But in the end she cannot be with her love, and she realizes this and does what is forbidden in the Underworld and defies time and sends back her love to whom he loved before her. Death in Cocteau’s Orpheus is not only powerful and vulnerable, but she also changes throughout the course of the movie. Three elements support that the Princess changes throughout the†¦show more content†¦She longs for him to come to her world with her, even though she knows that this is an impossible act, because no one in the underworld is allowed to love. She pursues her love anyways, and she starts to talk in a softer tone of voice. Instead of ordering, she talks so ftly of her love to Orpheus. She even begins to talk in a softer tone to Heurtebise and Cegeste. But her tone becomes more flat when she is in front of the Committee in the Underworld. Dialogue is only one way that Cocteau reveals the changing character of the Princess. The Princess’ clothing and appearance change as well throughout the various parts of the film. The Princess wears a very conservative black dress in the beginning of the film with her accessory being a long string of pearls and she is always seen smoking a cigarette. Her hair in the beginning of the film is pulled back into a very tight bun as well. This appearance emphasizes her harsh, authoritarian attitude. Once Eurydice’s death, the Princess emerges adorned in a much more revealing black dress and long black gloves. An interesting thing occurs when Heurtebise accuses the Princess of loving Orpheus; her dress turns white for an instant, but then back to black again. Her dress turns white again right before she crosses the mirror again into the Underworld. The Princess appears very modestly dressed and smokes again when she appears before the Committee of the Underworld. When

Forensic Entomology Drug Analysis

Question: Describe about the Forensic Entomology for Drug Analysis. Answer: 1. In the current situation, it is certainly possible to detect drugs concentration in corpses using maggots. Alternative specimens are provided by entomo- toxicology for detecting the drug in the body before death. However, in most cases, it cannot be used for toxicological interpretation particularly when skeletonised remains are left or when the body is in the advanced stage of decomposition (Morris Dadour, 2015). In such conditions, the larvae can be analyzed by using techniques such as mass spectrometry, or thin layer chromatography. Seasonal variation and climatic changes may affect the entomology results. There are several negative aspects to the use of maggots to test drug concentration found in the corpse. The drug can impact the developmental stages of the larvae (Gennard, 2012). According to Paul Verma, (2013) the "post-mortem drug distribution" and the stability of the "drug" in humans and insects may not always be well known. Consequently, it complicates the interpreta tion of entomotoxicological results from human cases, as it is not yet well established. Morris, Dadour, (2015) argued that there are ethical issues in such experiments, for example, the use of human liver for rearing larvae may be ethically questionable. Despite the controversy of the findings of the Campobassoet al.,(2004) and Tracquiet al., (2004), the fact which remains is the usefulness of maggots for drug assay. It is an important tool to identify the presence of drugs, which may not always be successful using conventional human tissue analysis (Paul Verma, 2013). Further, in addition to the presence of drugs, the PMI estimation must consider the impact on the development rate mortality. Therefore, the use of maggots for detecting drugs concentration in corpse will be effective when the validated experimental protocols and methods are established for entomotoxicological analysis and will be systematically applied (Dayananda Kiran, 2013). In my opinion, entomo- toxicology cannot be used to assess misuse of narcotics presently. It is an underlying fact that insects are highly sensitive (parts-per-trillion) in detecting drugs and it is possible to condition them with impressive speeds (Faris et al., 2016). However, due to lack of accurate data on the effect of toxins on the development of insects feeding on the corpse, the area of entomo- toxicology is limited in respect to narcotic usage. For example, the larval developmental is accelerated by the presence of cocaine or heroin in the corpse. Further, insect colonization is delayed by the presence of poisons like malthione (Steinhaus, 2012). Faris et al., (2016) explained that only when the rate of absorption of drugs exceeds the rate of elimination, the drug can be detected in larvae. The study also mentioned that the concentration of the drugs is difficult to be identified in pupae and third instars larvae. It led to a conclusion that the toxins are eliminated from th e larvae when the supply of toxin is diminished. Since forensic entomology is a new branch, there are limitations to entomo- toxicology. Therefore, this grey area still needs an intense research particularly the "bioaccumulation and insect metabolism of drugs." Hence, the assessment of deaths due to narcotic intoxication and the accuracy of the Entomological estimates is still under debate (Morris Dadour, 2015). 2. The role of an insect as the bioweapon has been evident from forensic entomology where insects are used to detect the elapsed time since death of the human corpse. Insects also play a great role in identifying drug use in human corpse before death (Faris et al., 2016). This area called Entomotoxicology is a new branch of forensic entomology and is well documented in the recent decade on criminal investigations (Dayananda, Kiran, 2013). In addition to the detecting time of death, the behavior of insects also plays a great role in understanding the cause of death or any other event that has occurred at the time of death. Here, insects have high potential to bring information in cases related to a child or elderly abuse or neglect. There are various other applications of insects in the field of biology. According to Ridgway, (2013), immune cells of insects such as Drosophila, Manduca much react in the same way as mammals thereby increasing their role in testing efficacy of new drugs. Further, the sensing method of insects is superior to mammals, which is advantageous in chemical detection (narcotics, explosives, etc.). However, it is still a big challenge for criminalistic and more particularly of the law enforcement to detect drugs, corpse, and explosives by a development of efficient techniques (Paul Verma, 2013). Other areas of research using insects include the study of gene alterations or deletions to assess the immune response in response to pathogen attack. The pathogenicity of the microbe can be measured by its growth in insect body, which also aids in detecting the virulence of mutants (Steinhaus, 2012). Further, exposing the insect cells to potential vaccines assists in determining the vaccine potent ial after challenging with the organism of interest (Pimentel Pimentel, 2006). There is a great deal of research in the development of "insect-sniffer detection systems which is yet to be proven for its ability. In conclusion, an insect is truly a bioweapon. There are several applications where insect as a bioweapon plays a great role. This is a case of over-stimulated imagination where scientist put forth their intellect to generate such bioweapon for public welfare. However, it can be the case of frightening reality when the potential role of an insect as the bioweapon is misused (Sarkar, 2010). For instance, it would be an easy opportunity for a terrorist to use swarms of insects to spread a deadly disease resulting in catastrophe. This may be harmful to both human and environment. The term forensic entomology is a broad field that involves interaction between arthropods and judicial system according to Gennard, (2012). The use of insects in post-mortem interval is under the area of the medico-legal field is really forensic. However, the use of insects as "biosensors or detectors was not yet considered in forensic entomology (Morris Dadour, 2015). It may happen so in future as the level of acceptance from the larger community of rese arch, and commercial enterprises may increase when there will be increased commercial applications of an insect as the bioweapon.
