Mise-en-scene, Psycho | Analysis

Mise-en-scene, Psycho | Analysis Mise-en-scene, psycho The mise-en-scene, a French term roughly translated as what is put into the scene (put before the camera), refers to all those properties of a cinematic image that exist independently of camera position, camera movement, and editing (although a viewer will see these different dimensions united in one image). Mise-en-scene includes lighting, costumes, sets, the quality of acting, and other shapes and characters in the scene. The Major reason that we tend to overlook or undervalue mise-en-scene in the movies is the powerful illusion of realism that is at the heart of the film medium (Corrigan, Timothy.45). Mise-en-scene usually involves some planning, but the filmaker may be open to unplanned events as well. An actor may add a line on the set, or an unexpected change in lighting may enhance a dramatic effect (Bordwell, David and Thompson, Kristin.156). Setting, costumes, lighting, and staging-these are the components of mise-en-scene. Yet one element seldom appears in isolation. Each usually combines with others to create a specific system in every film- (Bordwell, David.175). Mise-en-scene functions not in only isolated moments, but in relation to the narrative organization of the entire film (Bordwell, David.184). Alfred Hitchcocks Psycho (1960), a suspense horror film is one of the famous film which explores the conventional characteristics of film which are relevant to mise-en-scene. The film is encountered between two characters, Marion Crane (Janet Leigh) a secretary and Norman Bates (Anthony Perkins) the owner of the motel. Psycho starts with a title which is sliced up into halves from the middle, which depicts the split personality of Norman, who has been portrayed as psycho in the movie. The title is a reflection on his character. Psycho starts with showing the city of Phoenix, then the buildings and cars are shown from the top angle and then the camera pans to the window which is half closed , this also reflects the duality and shows that something suspicious is going to happen. Inside the room Marion is shown wearing a white underwear. In the next scene when she steals money from her employer and gets back home, she is then shown wearing a black underwear, which shows the difference b etween purity and evilness, because in white underwear she was shown pure, but after she steals the money, the black underwear signifies that she has done a crime and her sin has replaced her purity, and stealing money also shows an authority , as she got what she wanted and now she has control on things. And when she runs away from her home after stealing money, we see her wearing black dress, bag and shoes. Moreover her car was black as well portraying everything as evil. This beginning scene holds a grip on the audience which makes them stick to the screen. Psychos crucial and important scene is the murder of Marion in the shower, which is known as the Shower Scene. 77 camera angles are featured in this scene, and most of the shots are close ups and extreme close ups. When Marion enters the bathroom, everything is shown completely white, which shows purity, where as Marion is not pure so it signifies that she is taking a shower to clean all of her sins Then the scene starts continuing in different shots and camera angles which shows that something is about to happen, and then there is a silhouette shot of Marion which signifies that things are going to go on a darker side from white. The use of close shots is to make the scene feel longer and more subjective. There are some mediums shots, which are shot before and after the murder, the reason they are not shot between the murder is to show violence and to make the audience feel as they are seeing a murder in reality and while the murder is happening, the audience can feel the helplessne ss of Marion, and that she is in danger and needs help but there is not one to help her, so audience feel like going into the scene and help her out. Hitchcock is famous for using these kind of shots to make the audience go crazy and feel the reality and here comes the suspension of disbelief which makes the scene more interesting for the audience. The murder ends with a medium shot where blood is pouring into the drain of the tub which shows the end of Marions life. One of the other important scene is the parlor scene, when Marion is eating her sandwich the camera is placed on her eye level so the audience could feel that they are sitting with Marion and having a conversation with her, and for Norman the camera is low angled which shows that his life is out of balance, and something wrong is going on, because nobody is comfortable on viewing the world from such a position. Then the props and costume has played an important role in this scene, especially the eagle and other stuffed birds on the wall. This portrays the motel as a mad house, builds up frightening moment of the scene and signifies that something wrong is going to happen. Marions clothes are light in color, and her posture is very relaxed where as Norman is wearing dark clothes which portrays him as dominant, wicked evil man and it also shows that Marion will be soon victimized by the hands of Norman. The use of mise-en-scene in this scene is very effective as it previews what is goi ng happen next in the narrative. There are many things which are used as motif in Psycho with in the mise-en-scene. For example, the use of bathroom in the beginning, then the bathroom is shown twice and then the most important murder scene which also occurs in the bathroom. The use of close up shots of the eyes to show the emotions and the nature of the character that the audience could feel. These eye shots are the key shots of the film and nicely used as motif, and the eye with close up is a perfect way to show the goal for violence act. For example after the murder, when we see the blood draining into the drain of the tub, the drain transforms into the eye of the victim, who is lying dead on the bathroom floor. The shots of mirrors are also repeated couple of times to show the mirror image and the dual personality of the character. Birds have been used as a motif, be it stuffed birds in the parlor or the frames in the motel room, this signifies that Marion who came in the motel, she was not less than a stuffed b ird on wall or a frame, who could not fly back ever again, as she was murdered by the psycho man. Even when Norman was taking her dead body out of the room, the frame falls down, which shows the end of her life. The car was also used a motif, it was Morains death that was calling her into the motel and it was the car that took her into it. Then the use of low angle and high angle shots through out the course of the film as a motif to make audience feel comfortable and uncomfortable in different situations throughout the movie. Further looking towards the lighting in Psycho, Hitchcocks artistry in lighting and mise-en-scene created a world that is submerged with duality. For example, the parlor scene, where there is a small place, and it is occupied with a lot of stuff, just to show an uncomfortable situation between Marion and Norman, and there is only one source of light which is coming from the lamp, which is the key light in that whole frame. The way these characters are lit by only one source of light and the way they are positioned is done so well that their emotions are valid, and the audience can tell whats going on in the characters mind. For example, when Marion is sitting on a chair, on that time her face is very well lit, which doesnt hide her in shadows as she has stolen 40,000 dollars, but the high key lighting on her face shows that she is not on a darker and evil side, it creates softness and shows that shes having an intension of returning the stolen money. Where as Norman is not well lit in this scene, the back and fill lightening is very minimum because of which he is in shadows, which shows his dual personality and that he is hiding something. In the last scene, when Norman is shown in the jail, we see that he is clad in a black blanket portraying him as a villain and wicked facial expressions on his face shows the evilness of his character and that he is not guilty of what he did, infact he was a truly psycho man. The movie ends with the last scene where we see the car carrying Morains dead body emerging out of the water, which has been used as motif throughout the film. Overall, Hitchcock has done an amazing job with Psychos mise-en-scene with the mixture of camera angles, lightening and editing, and the use of these elements from the beginning till end, and the contribution of these all have added sense to the concept, as the use is justifiable and gain audiences interest. Stages of Decomposition: Effect of Time and Temperature Stages of Decomposition: Effect of Time and Temperature Chapter I INTRODUCTION Watson, can you determine cause and time of death? I knelt over the woman and began a cursory examination â€Å"Rigor mortis has set in, so Id estimate shes been dead about 10 to 12 hours. Holmes stood up and brushed himself off with his hands. So, that puts her death between midnight and 2 am†(Anonymous 2007). After the question of cause of death; the question of time of death is the most sought after piece of information associated with a medical death investigation. As a consequence, death investigators find themselves in need of a means of ascertaining the period of time between when an individuals body is found and when they died, sometimes referred to as the post mortem interval. Establishing the time of death through the determination of post mortem interval may have a direct bearing on the legal questions of guilt or innocence by confirming that a suspects alibi covers the period when the victim died, or demonstrating that it does not. If the time of death can be established to within hours, days, months or even years, an individual may be able to prove that they were at some other place at that time. On the other hand, if the suspect is known to have been in the vicinity of the victim during the appropriate time period, then they can be shown to have had an opportunity to commit th e crime. Currently, there are multiple techniques for determining post mortem interval that incorporate methods in almost every discipline of forensic science. Depending on the circumstances, these techniques can yield results that vary from a narrow accurate estimate (video of the victim, the victims stopped watch etc.) to a wide range estimate (counting tree rings on trees growing over or through the remains). Regardless of the of the method used, the calculation of post mortem interval is at best an estimate and should not be accepted as accurate without considering all of the factors that can potentially impact the result. Post Mortem Interval Estimation â€Å"For everything there is a season, And a time for every matter under heaven: A time to be born, and a time to die†¦Ã¢â‚¬  Ecclesiastes 3:1-2 The techniques currently utilized for estimating post mortem interval can be broken down into two broad categories based upon the methodology used. The first of these categories are the concurrence-based methodologies. Concurrence based methods relate or compare the occurrence of a known event, which took place at a known time, with the occurrence of death, which took place at an unknown time. Examples of concurrence-based methods include the determining the years of manufacture of clothing found on a body, tree ring development, dates on personal effects, etc. Concurrence based methods rely on both evidence associated with the body, and anamnestic evidence such as the deceaseds normal pattern of movements. The second grouping of techniques include rate of change methodologies. Rate of change-based methodologies measure some aspect of a evidence, directly associated with the body, that changes at a known or predictable rate and is started or stopped at the time of death. Examples of the rate of change based methods include body temperature, tissue decomposition, insect succession and bone weathering. Some of these methodologies can be considered to fall into both categories. Examples of these would be tree ring development (Coyle, Lee et al. 2005) and insect succession. Previous post mortem interval Estimation Methods The variety of approaches for estimating post mortem interval spring from the varied expertise and experiences of their proponents as such the different methods tend to be focused on the immediate needs of the investigator, and limited to a particular stage of the post mortem interval or type of observation. As a consequence, the period of time for which a procedure is effective will overlap others. Algor, Rigor and Liver Mortis â€Å"Tis after death that we measure men.† James Barron Hope The earliest recorded methods for estimating early post mortem interval were a rate of change methodology based on the most easily observed changes. The cooling of the body after death (algor mortis), the gradual stiffening of the body (rigor mortis) and the fixed pooling of the blood resulting in discoloration of the lower portions of the body (livor mortis) can be easily assessed with minimal or in some instances no instrumentation. Since the time of the ancient Greeks when the following rule of thumb was developed: Warm and not stiff: Not dead more than three hours; Warm and stiff: Dead between 3 and 8 hours; Cold and stiff: Dead between 8 and 36 hours; Cold and not stiff: Dead more than 36 hours; (Starkeby 2004) until modern times, the basis of most temperature based post mortem interval analyses is the assumption that the human body, which averages 98.2 oF +/- 1.3 oF (Mall and Eisenmenger 2005), was at 98.6 oF (Mackowiak, Wasserman et al. 1992) at death and that after death the body looses heat in a predictable manner. There have been many temperature based methods for estimating post mortem interval. As early as the 1800s, Dr. John Davy had developed a method using the fall in body temperature (algor mortis), measured rectally, to determine the post mortem interval (Henssge and Knight 2002). This method was refined by De Saram by recording detailed temperature measurements collected from executed prisoners (De Saram G. 1955). More recent approaches to this technique have included measuring rectal temperature, body surface temperature, ear canal temperature, eye socket temperature and liver temperature (Simonsen, Voigt et al. 1977; Henssge and Knight 1995; Baccino, De Saint Martin et al. 1996; Kanetake, Kanawaku et al. 2006). Improvements to these techniques have included multiple progressive sampling, and the introduction of concepts such as the initial temperature plateau, core temperature, heat gradients, the effects of insulation, the ratio of surface area to volume, the effects of humidity and the effect of conductive surfaces, Microclimates and postmortem skin cooling (Green and Wright 1985; Nokes, Flint et al. 1992; Nelson 2000). However, most methods that attempt to use body temperature changes to determine the post mortem interval are hampered, as most methods are, by individual variability. Even when complex calculations and algorithms have been designed to model for tissue density, initial temperature distribution, post mortem exothermic reactions and heat loss, these refinements have not appreciably narrowed the estimate window for post mortem interval. Multiple studies outlining instances of initial temperature increase of a body soon after death (Hutchins 1985) associated with post mortem chemical changes such as rigor mortis, cell lysis and the conversion of cellular energy production to anaerobic respiration (Nelson 2000); variations in the core body temperature ranging from 0.5 1.2  °C during a 24 hour period (Chisholm 1911; Mackowiak, Wasserman et al. 1992); the effect of variable environmental temperatures (Green and Wright 1985; Green and Wright 1985); and the effect of environmental temperatu re on overall body surface temperatures (Mall, Hubig et al. 2002) have all contributed to limit the usefulness temperature as a consistent indicator of post mortem interval. Additionally, once the body has reached ambient temperature temperature ceases to be a factor. Marshall said it best when he said ‘‘It would seem that the timing of death by means of temperature can never be more than an approximation(Henssge and Knight 1995). Soft and Hard Tissue Decomposition â€Å"Now, a corpse, poor thing, is an untouchable and the process of decay is, of all pieces of bad manners, the vulgarest imaginable†¦Ã¢â‚¬  Aldous Huxley Cadaveric decomposition is a complex process that begins immediately following death and proceeds beyond the time when recognizable human remains have ceased to exist. Decomposition can be broken down into two major stages. The first stage, soft-tissue decomposition, is caused by autolysis and putrefaction. Autolysis is the digestion of tissue by cellular enzymes and digestive processes normally present in the organism. Putrefaction is the digestion of whole tissues systems caused by the enzymatic activity of fungi and bacteria that are either present in the organism or the environment that opportunistically invade the tissue. Both autolysis and the microorganisms responsible for putrefaction are normally held in check in living organisms. However, when an organism dies the cellular and systemic mechanisms responsible for regulating autolysis and inhibiting putrefying microorganisms stop. â€Å"Without these controlling processes the body becomes fancy (bacterial) culture media† (Carayannopoulos 1992). These early postmortem changes in soft tissues can be used to provide an estimate of the post mortem interval from death until skeletonization. However, the rate of soft tissue decomposition can be dramatically affected by both internal and external factors that affect the body (i.e. ambient temperature, cause of death, scavenging, trauma, environmental conditions, clothing, body size, mummification and adipocere formation) (Rodriguez and Bass 1985; Micozzi 1986; Mant 1987; Vass, Bass et al. 1992; Komar 1998; Campobasso, Di Vella et al. 2001). There are reported instances of rapid decomposition associated with acute illness (Frisch 2001) and the author is personally aware of an instance of a post mortem interval of less than eleven days resulting in complete skeletalization of an individual that died of complications related to Acquired Immunodeficiency Syndrome (Watson 1994). Additionally, there are a number of examples of bodies remaining intact for year s after death (Bass and Jefferson 2003). Beyond gross observation for assessing decomposition, researchers have developed multiple morphometric and chemical methods for assessing soft tissue decomposition. These have ranged from early (ca.1800s) methods such as the Brouardel method which examined the shift in flammability of putrefaction gases in the early post-mortem interval, and the Westernhoffer-Rocha-Valverde method examining the formation of crystals in the blood formed after the third day of putrefaction (Cengage 2006); to more modern methods such as ultrasound assessments of organ condition (Uchigasaki, Oesterhelweg et al. 2004) and the use of electron microscopy to examine measurable physical changes in mitochondria (Munoz, de Almeida et al. 1999) and platelet count (Thomsen, Kaatsch et al. 1999). Chemical methods used to assess time since death include the assessment of volatile organic compound formation (Vass, Bass et al. 1992; Statheropoulos, Spiliopoulou et al. 2005; Statheropoulos, Agapiou et al. 2007; Dekeir sschieter, Verheggen et al. 2009); the concentrations of non-protein nitrogen (Sasaki, Tsunenari et al. 1983; Gallois-Montbrun, Barres et al. 1988) and creatinine (Gallois-Montbrun, Barres et al. 1988; Brion, Marc et al. 1991). Bony tissue decomposition, the second major stage of decomposition, consists of a combination of surface weathering due to environmental conditions (temperature, humidity, sunlight) and erosion from soil conditions (pH, mineral content, etc.) (Behrensmeyer 1978; Janjua and Rogers 2008). While not much detailed study has been done on the environmental factors that affect bony tissue breakdown, it has been established that environmental factors such as pH, oxygenation, hydrology and soil flora and fauna can affect the long term stability of collagen (Garlick 1969; Henderson 1987; Bell, Skinner et al. 1996). Collagen, the primary protenatious component of bone, slowly hydrolyzes to peptides and then to amino acids leading to the breakdown of the collagen-mineral bonds which weakens the overall bone structure leaving it more susceptible to environmental weathering (Henderson 1987). By examining the effects of related changes (cracking, flaking, vacuole formation, UV-fluorescence of compa ct bone) the investigator can estimate the period of time a bone sample has been exposed to weathering (Yoshino, Kimijima et al. 1991; Bell, Skinner et al. 1996; Janjua and Rogers 2008; Wieberg and Wescott 2008). Current methods of assessing time since death using bone weathering rely heavily upon the experience of the investigator (Knight and Lauder 1969) and are limited to immediately post skeletalization to 10 to 100 years based on environmental conditions (Haglund and Sorg 1997). As with the assessment of soft tissue decomposition for time since death, investigators examining bone decomposition have supplemented observational methods with quantifiable testing techniques that analyze changes that are not directly affected by the physical environment (Lundquist 1963). Radiocarbon dating of carbon-14 and strontium-90 have been used to group remains pre and post 1950 (Taylor, Suchey et al. 1989; Maclaughlin-Black, Herd et al. 1992). Neis suggested that, with further study of strontium-90 distributions, determination of times since death should be possible (Neis, Hille et al. 1999). Bradley suggested that measuring the distribution of 210Pb and 210Po in marrow and calcified bone could prove forensically significant (Bradley 1993). This work was built upon by Swift who evaluated using 210Pb and 210Po distribution in conjunction with trace element analysis to provide a meaningful estimate of the post-mortem interval (Swift 1998; Swift, Lauder et al. 2001). Maclaughl in demonstrated that chemical changes due to environment could measurably affect isotope levels (Maclaughlin-Black, Herd et al. 1992). In addition to radionucleotide studies, investigators have also measured the changes in both organic (amino acids, urea, proteins, DNA) and inorganic compounds (nitrogen, potassium, sulphur, phosphorous) in bone. (Jarvis 1997; Prieto-Castello, Hernandez del Rincon et al. 2007). Stomach Contents/Rate of Digestion â€Å"Govern well thy appetite, lest sin surprise thee, and her black attendant Death.† John Milton The presence or absence of food in the stomach is often used as an indicator of post mortem interval. Its use as an indicator of post mortem interval is predicated on the assumption that under normal circumstances, the stomach digests and empties at a predictable rate taking from two to six hours to eliminate a full meal (Jaffe 1989). If a person had eaten a light meal the stomach would empty in about 1.5-2 hours. For a medium-sized meal the stomach would be expected to take about three to four hours to empty. Finally, a large meal would take about four to six hours to exit the stomach. Regardless, it would take from six to eight hours for the initial portion of the meal to reach the large intestine (Hallcox 2007). This information, coupled with reliable ante-mortem information relating to when an individual last ate is used by some pathologists when providing an estimate of the times since death. It is for this reason, among others, that comprehensive autopsies usually include an ex amination of the stomach contents (Batten 1995; Siegel 2006). Although it provides another useful indicator of time since death, there are serious limitations to the assessment of the stomach contents as an accurate indicator of time since death. Its reliance on reliable anamnestic evidence such as eating habits, the extent to which the victim chews their food (Pera, Bucca et al. 2002), the physiological state of the victim (Troncon, Bennett et al. 1994; Jayaram, Bowen et al. 1997; Lipp, Schnedl et al. 1997; Phillips, Salman et al. 1997) and the state of mind of the victim (Jaffe 1989); as well as verifiable antemortem evidence such as what the last meal consisted of (protein vs. fiber vs. fat)(Dubois 1985; Tomlin, Brown et al. 1993), the amount of liquid consumed with the meal, alcohol consumption and the time when it was consumed limits its usefulness to a small number of cases (Jaffe 1989). These factors combined with evidence that digestion can continue after death (Koersve 1951) makes the estimation of post mortem interval using stomach co ntents difficult at best. Insect Succession â€Å"Buzzards gotta eat, same as worms.† Clint Eastwood from the Outlaw Josey Wales Insect colonization of a body begins within hours of death and proceeds until remains cease to be a viable insect food source. Throughout this period, multiple waves of colonization by different insect species, as well as multiple generations of previously established species can exist. Forensic entomologists can use the waves of succession and generation time to estimate the postmortem interval based on the variety and stage of development of the insects, or insect remnants, present on the body (Archer and Elgar 2003). In addition to information regarding time since death, forensic entomology can provide useful information about the conditions to which the body was exposed. Most insects have a preference for specific conditions and habitats when colonizing a body and laying their eggs. Modifications to that optimal habitat can interrupt the expected insect colonization and succession. The presence of insects or insect larva that would typically be found on bodies colonized indoors o r in shade on a body discovered outside in direct sunlight may indicate that the body was moved after death (Sharanowski, Walker et al. 2008). Aquatic insects found on bodies discovered on land could indicate the body was originally in water (Wallace, Merritt et al. 2008; Proctor 2009). Although insect succession varies by season, geographical location and local environmental conditions, it is commonly assumed to follow a predictable sequence within a defined habitat. While there are a multitude of studies that have examined regional succession patterns (Archer and Elgar 2003; Tabor, Brewster et al. 2004; Tabor, Fell et al. 2005; Martinez, Duque et al. 2007; Eberhardt and Elliot 2008; Sharanowski, Walker et al. 2008) these studies use different approaches towards defining habitat and assessing insect succession making cross-comparisons of their data difficult. Also, the majority of these studies do not rigorously address the statistical predictability of a species occurrence making their results of limited use as post mortem interval indicators (Michaud and Moreau 2009). Additionally, beyond the presence or absence of clothing, the majority of the post mortem entomological studies conducted do not examine non-habitat external factors that may affect succession. For example, only a few studies have been conducted that assess the affect of drug ingestion (George, Archer et al. 2009) or the presence of chemicals (bleach, lye, acid etc.) used to cover-up evidence (Charabidze, Bourel et al. 2009) on the insect life cycle. As with other means of assessing time since death, more extensive studies with different insect species and drugs in a wider variety of habitats is necessary. Electrolyte Concentration â€Å"Death is a low chemical trick played on everybody†¦Ã¢â‚¬  J.J. Furnas Cellular activity does not immediately cease when an organism dies. Rather, individual cells will continue to function at varying metabolic rates until the loss of oxygen and metabolic substrates caused by the cessation of blood flow results in hypoxia (low oxygen). As cell metabolism shifts from aerobic to anaerobic, oxidative phosphorylation and ATP generation, the cellular processes keeping autolysis in check, begin to decrease and eventually cease all together. Without energy to maintain osmotic gradients membranes begin to fail. As lysosomal membranes begin to fail the enzymes within are released and begin consuming the cell from the inside out. With autolysis comes a cascade of metabolic chemicals, released ions, originally bound up in various cellular processes begin to diffuse due to the diffusion gradient according to Ficks law into the intracellular spaces (Madea 2005). Forensic researchers have used the presence, absence or effects of inorganic ions such as potassium, phos phorous, calcium, sodium and chloride as a means of estimating time since death (Schleyer and Sellier 1958). In most instances the higher the concentration gradient, the more suitable is the analyte for the estimation of the time since death. When analyzing body fluids for the purposes estimating post mortem interval, early researchers tended to focus their studies on body fluids such as, cerebrospinal fluid, blood and pericardial fluid (Schleyer and Brehmer 1958; Coe 1972; Henssge and Knight 1995; Yadav, Deshpande et al. 2007) with a few others examining other compartmentalized bodily fluids (Madea, Kreuser et al. 2001) and the largest numbers focusing on vitrious humor (Madea, Henssge et al. 1989; Ferslew, Hagardorn et al. 1998; Madea and Rodig 2006; Kumagai, Nakayashiki et al. 2007; Thierauf, Musshoff et al. 2009). Chemical methods used to assess these analytes in blood and spinal fluid as an indicator of post mortem interval have failed to gain general acceptance because, for th e most part, they failed to produce precise, reliable, and rapid results as required by the forensic community (Lundquist 1963). Current chemical methods which have primarily focused on vitreous fluid tend to suffer from the same limitations demonstrated by the fact that with notable exceptions (Pounder 1995) very few statistically rigorous field studies on the reliability and precision of estimating post mortem interval are available in the literature (Coe 1993; Madea 2005). Enzyme Activity As previously discussed, cellular activity does not cease when clinical death occurs. In any circumstances where the cellular metabolism shifts from a homeostatic balanced state to an imbalanced state biochemical changes occur. Changes in the levels and/or activity of enzymes (i.e. cardiac troponin, c-reactive proteins, and G proteins) have long been used as indicators of cellular stress (Li, Greenwood et al. 1996; Katrukha, Bereznikova et al. 1998; Tsokos, Reichelt et al. 2001; Uhlin-Hansen 2001). Assessing similar changes in cellular biochemistry as a function of time since death provides investigators with a wide variety of tissues, testing methods and analytes for consideration. As a consequence, forensic investigators have assessed and suggested enzymes from heart, pancreas, muscle, blood and brain as potentially suitable markers for time since death (Wehner, Wehner et al. 1999; Wehner, Wehner et al. 2001; Kang, Kassam et al. 2003; Jia, Ekman et al. 2007; Poloz and ODay 2009). C omparisons of total proteins analyzed ante and post mortem analyzed using two dimensional gel electrophoresis and Matrix Assisted Laser Desorption/Ionization Time-of-Flight have demonstrated changes in metabolic enzymes, (Jia, Ekman et al. 2007; Hunsucker, Solomon et al. 2008). Assessing the changes in enzyme activity provides examiners a means to assess time since death, in many instances long before visible cellular changes. However, in at least a few of these studies results indicate that enzyme degradation during extraction and partial enzyme activity observed with degradation products these markers better suited to qualitative analysis rather than quantitative analysis (Sabucedo and Furton 2003). Muscle/Nerve Excitation Both neurons and myocytes retain the ability to respond to electrical stimulation for at least a short period of time after organism death. (Sugioka, Sawai et al. 1995; Briskey, Kastenchmidt et al. 2002; Sams 2002). The response of nervous and muscle tissue to external electric stimulation has also been investigated and proposed as means to estimate time since death (Kline and Bechtel 1990; Straton, Busuttil et al. 1992). Methods developed to investigate myocyte excitability assess the relative magnitude and duration of the muscle contraction during the application of external stimulation. To assess the contractile response, a combination of observational based assessments (Madea 1990; Jones, James et al. 1995) and measurement based assessments (Henssge, Lunkenheimer et al. 1984; Madea 1992) have been suggested and reported. Similar investigations have examined post mortem excitation of nervous tissue by measuring a variety of neurological reactions to stimuli. These include the alteration of Compound Muscle Action Potential (Nokes, Daniel et al. 1991; Elmas, Baslo et al. 2001; Elmas, Baslo et al. 2002), lengthen of the refractory or non-propagating period immediately following the CMAP (McDowall, Lenihan et al. 1998), the extracellular impedance/resistance (Querido 2000), the chronaxie measurement or the time over which a current double that necessary to produce a contraction is applied before the contraction occurs (Straton, Busuttil et al. 1992) and the changes in the amplitude of the F-wave (the secondary CMAP observed after the initial CMAP) have all been examined, and been suggested as potential indicators of time since death. The results of studies examining the response of excitable tissue to electric stimulation have been consistent in that the stimulation response varies predictably over time. However, suitability for absolute indicators of time since death remains in questions as investigators have reported contradictory results related to the effect of the manner of death on the stimulation response (Madea and Henssge 1990; Elmas, Baslo et al. 2002). RNA Degradation RNA degradation, both antemortem and postmortem, is a complex process that is not well understood. Unlike with DNA degradation, continuous degradation of inducible mRNAs by native ribonucleases is used as a means of translational control. After cell death these ribonucleases, no longer kept in check by the mechanisms of cellular homeostasis, combine with exogenous ribonucleases from bacteria and fungi to begin un-inhibited digestion of all cellular RNA. Investigators have noted extensive variability in RNA degradation rates in different tissues (Bauer 2007). Not surprisingly such variability appears to be related to the antemortem ribonuclease activity of the tissue; with relatively ribonuclease poor tissues such as brain and retina exhibiting greater RNA stability (Johnson, Morgan et al. 1986; Malik, Chen et al. 2003) when compared to ribonucleases rich tissues such as liver, stomach and pancreas (Humphreys-Beher, King et al. 1986; Finger, Mercer et al. 1987; Bauer, Gramlich et al. 2003). Additionally, but also not surprisingly, some constitutively expressed mRNAs have been shown to be more stable, or perhaps simply more prevalent, than inducible mRNAs (Inoue, Kimura et al. 2002). Additionally, while intrabrain mRNA levels are fairly constant, interbrain levels vary considerably (Preece, Virley et al. 2003). As a consequence of these observations, the degradation of RNA (total and/or mRNA) have been suggested as a potential analyte to assess time since death. Researchers examining the effect of post mortem interval on RNA stability have examined a variety of targets (mRNA, both tissue specific and constitutively expressed, and total RNA) with an assortment of methods including Reverse Transcriptase (RT) PCR(Ohshima and Sato 1998; Fleige, Walf et al. 2006; Haller, Kanakapalli et al. 2006; Zhao, Zhu et al. 2006), RNA (cDNA) microarrays (Bahn, Augood et al. 2001; Catts, Catts et al. 2005; Son, Bilke et al. 2005; Popova, Mennerich et al. 2008) and quantitative RT-qPCR (VanGuilder, Vrana et al. 2008). Based on these studies, there are indications that beyond time and temperature, factors such as hypoxia, tissue pH, antemortem physiological conditions (coma, seizure activity and injury) postmortem transcriptional activity and RNA sequence can dramatically affect the stability and measurable levels of RNA (Burke, OMalley et al. 1991; Harrison, Heath et al. 1995; Ohshima and Sato 1998; Catts, Catts et al. 2005; Bauer 2007). When examining the sem inal question regarding time since death and temperature some researchers have reported temperature and time as significant factors affecting mRNA levels (Burke, OMalley et al. 1991), while others have reported the reverse (Harrison, Heath et al. 1995; Preece and Cairns 2003). These contradictory data are not surprising given the changes in the specificity, sensitivity and application of the assays used; however, the ultimate question has not been resolved. What is clear from the research is that RNA degradation (mRNA or total) is a complex process (Preece and Cairns 2003; Preece, Virley et al. 2003; Heinrich, Lutz-Bonengel et al. 2007) effected by multiple factors indicating more study will be required before RNA degradation can be considered a reliable indicator of time since death. DNA Degradation and its Effect on DNA Typing Since the initial application of molecular biology techniques to samples of forensic significance in the latter half of the 1980s, forensic scientists have noted that increased exposure to environmental insults can negatively impact DNA quality. Developmental validation studies performed to evaluate the efficacy of new typing techniques (SWGDAM 2008) have found that environmental variables such as heat, high humidity, direct moisture, fungal/bacterial contamination and ultraviolet light can impact the quantity or quality of the DNA sample making them unsuitable for DNA analysis (McNally, Shaler et al. 1989; Graw, Weisser et al. 2000; Takayama, Nakamura et al. 2003; Bender, Farfan et al. 2004; Schneider, Bender et al. 2004; Niemcunowicz-Janica, Pepinski et al. 2007). During transitions in technology from Restriction Fragment Length Polymorphism (RFLP) analysis to Polymerase Chain Reaction (PCR) based testing, researchers noted that samples too degraded to produce an RFLP pattern could still produce profiles using a variety of PCR based markers that evaluated loci shorter in length (Hochmeister, Budowle et al. 1991). This finding supports the hypothesis that degradation in the forensic setting is (not surprisingly) processive. Additional research found that while the DNA in some samples like cadaveric blood and kidney tissue could degrade to the point where it was no longer suitable for DNA fingerprinting after as little as a week (Ludes, Pfitzinger et al. 1993); other samples such as bone (Hochmeister, Budowle et al. 1991; Frank and Llewellyn 1999) and teeth (Schwartz, Schwartz et al. 1991; Pfeiffer, Huhne et al. 1999) could, under most conditions, provide typeable DNA for months. The fact that DNA degradation has a detrimental effect on larger genetic loci, and affects different tissues at different rates is considered to be of extraordinary forensic significance is evidenced by the numbers of studies that seek to examine, and overcome this effect (42 validation studies specifically mentioning DNA degradation from 1995-2009 in PubMed). This makes perfect sense when the observer considers the impact that degradation can have on selecting suitable samples and evaluating the resultant DNA profiles. However, a number of researchers have looked beyond the simple question of how degradation affects the typing of samples to broader questions such as the mechanisms of postmortem degradation (De Marà ­a and Arruti 2004; Foran 2006) and synthesis (Oehmichen, Frasunek et al. 1988) and how that knowledge can be used to assist in the assessment of time since death. DNA degradation by RFLP: Since Sir Alec Jeffreys first applied Southern blotting (Southern 1975) techniques to the testing of forensically significant samples in 1985 (Jeffreys, Brookfield et al. 1985) DNA analysis has revolutionized forensic science. Restriction Fragment Length Polymorphism DNA analysis relies on variations in the lengths of DNA fragments generated by enzyme restriction. With restriction fragments ranging from approximately from 2 33 kilobases (Baird, Balazs et al. 1986) successful typing and analysis requires high quality (un-fragmented) DNA. Researchers noted from the outset that in some cases involving older and/or postmortem samples that DNA degradation, tied to the exposures of higher temperatures, resulted in the gradual disappearance of the longer fragments reducing the evidentiary value of older samples (Bar, Kratz

The aims and objectives of our study were to characterize pathologies of paranasal sinuses on MDCT, to delineate their anatomical location, extension and bony involvement and to correlate the multi detector computed tomography findings with clinical/surgical/histopathological/ microbiological findings. A total of 100 patients who came with complaints referring to nose and paranasal sinuses were included in the study. All patients were subjected to MDCT PNS after detailed clinical examination. The imaging findings are correlated with other investigations. Key imaging features considered were significant anatomical variations, site of involvement, bony and soft tissue changes, invasion of surrounding structures, pathognomic features and correlation with clinical complaints/surgical/pathological/microbiological findings. Among 100 patients in our study, there were 15 patients in 0 20 years age group, 36 patients in 21 40 years age group, 37 in 41 60 years age group and 12 were greater than 60 years. The age group of patients ranged from minimum of 9 months to maximum of 81 years. The highest number of patients were in 41 60 years age group. The study comprised of 65 males and 35 females. The number of male patients were higher than the female patients. The patients were divided into five categories: bacterial sinusitis, fungal sinusitis, benign tumors, malignant tumors, and miscellaneous. 84 patients presented with sub acute or chronic bacterial sinusitis, 4 patients were of fungal sinusitis, 4 patients presented with benign tumors, 3 patients with malignant tumors and 5 patients with other miscellaneous conditions. Various anatomical variations were encountered during our study. One or the other anatomic variation was found in 99 cases ( 99% ). Of the structures around ostiomeatal unit, giant bulla ethmoidalis was found in 35 cases, middle turbinate pneumatisation in 33 cases, paradoxical curvature of middle turbinate in 19 cases. Haller cell was found in 15 cases. Type 1 frontal sinus drainage pathway in 78 cases, type 2 frontal sinus drainage pathway in 21 cases. Deviated nasal septum with or without septal spur in 55 cases, inferior turbinate hypertrophy in 30 cases, accessory maxillary ostia in 26 cases, and agger nasi cell in 93 cases. Type 1 optic nerve course was found in 53 cases, type 2 in 14 cases, type 3 in 9 cases, and type 4 optic nerve course along with Onodi cells in 23 cases. Type 1 anterior clinoid process pneumatisation was found in 10 cases, type 2 pneumatisation in 1 case. Sphenoid septum lateral attachment in 7 cases, and sphenoid sinus septum pneumatisation in 14 cases. Among 84 patients with bacterial sinusitis, 26 patients presented with sporadic pattern, 23 patients with infundibular pattern, 23 patients with ostiomeatal unit pattern, 8 patients with polyposis pattern, and 4 patients with sphenoid recess pattern. The various causative factors which came across in infundibular pattern were Haller cells in 6 cases, giant bulla ethmoidalis in 6 cases, uncinate process pneumatisation in 1 case, and mucoperiosteal thickening in 10 cases. The various causative factors for ostiomeatal pattern which were found during our study were: inferior turbinate hypertrophy in 6 cases, giant bulla ethmoidalis in 6 cases, deviated nasal septum with or without septal spur in 4 cases, concha bullosa in 3 cases, concha lamella in 2 cases, agger nasi cell in 1 case, and paradoxical middle turbinate in 1 case. The various findings which were encountered in bacterial sinusitis in our study were: mucoperiosteal thickening in 84 cases, ostiomeatal unit block in 31 patients, bone thickening in 20 patients, bone thinning in 8 cases, and bone sclerosis in 6 patients. Among 4 patients with fungal sinusitis, the various findings were: bilateral / multisinus involvement was found in 4 cases, expansion of any involved sinus was found in 4 cases, intrasinus hyperdensity was found in 4 cases. Bony thinning was found in 4 cases, bony erosions and nasal cavity involvement was found in 3 cases. The various findings in 4 cases of benign tumors seen ( 1 inverted papilloma, 1 juvenile angiofibroma and 2 ivory osteomas ) were: bony thinning in 2 cases, bony remodelling in 2 cases, multisinus involvement in 2 cases, intracranial extension in 1 case, and intra orbital extension in 1 case. Bony destruction, bone thickening/sclerosis, and calcification were not seen in any of the cases. Among 3 cases of malignant tumors (squamous cell carcinoma, embryonal rhabdomyosarcoma, and esthesioneuroblastoma), various findings were: : Bony destruction in 3 cases, bony thinning in 3 cases, bony remodelling in 0 cases, multisinus involvement in 2 cases, intracranial extension in 2 cases, and intra orbital extension in 2 cases. Bone thickening/sclerosis, and calcification were not seen in any of the cases. Under miscellaneous category we encountered one case each of periapical cyst, oro-antral fistula, granulomatous polyangitis, monostotic fibrous dysplasia, and Langerhans cell histiocytosis. In our study we found sensitivity and specificity for bacterial sinusitis as 100% and 94.11% respectively. The fungal sinusitis had sensitivity and specificity of 75% and 100% respectively. Benign, malignant tumors and others had sensitivity and specificity of 100%. The diagnostic accuracy for bacterial sinusitis and fungal sinusitis was 99%, and the diagnostic accuracy of benign, malignant tumors and other miscellaneous conditions was 100%. The p value was obtained after applying Fischer Exact test. The p value obtained was statistically significant for all the disease conditions. Based on the statistical values it can be inferred that multi detector computed tomography is useful to characterize paranasal sinuses lesions and also delineation of anatomical location, extension and bony involvement. There are certain limitations in our study. Our findings cannot be generalised to the whole population because of the limited sample size. However, our findings add value to the research done. The role of contrast cannot be adequately studied. The role of MRI in various paranasal sinus pathologies was not evaluated. CONCLUSION Paranasal sinus diseases are very commonly encountered problems in clinical practice. Clinical assessment alone is not sufficient to reach a diagnosis, as the presentation of most of the conditions is nonspecific. Imaging forms the mainstay not only in making correct diagnosis, but also to know the extent of lesion, pre-operative assessment of the sinonasal anatomy and commonly encountered anatomic variations. X ray has low sensitivity, specificity, positive and negative predictive values. CT is highly sensitive and specific in determining the presence of paranasal sinus pathology and clearly demonstrates the complex anatomy. The introduction of multi detector CT has transformed the axial imaging modality into a volumetric one and allows the pathology to be displayed in any desired plane. The capability of thin-section acquisition improves visualisation of tiny pathological details, and the isotropic nature of high spatial resolution data sets enables display in multiple planes, obviating image acquisition in prone or hyper extended patient position. Recommendations: 1. MDCT has proved to be highly sensitive in classifying the lesions into clinically relevant categories, making diagnosis and more so in knowing the extent of involvement with a high diagnostic accuracy. 2. MDCT is an indispensible tool before Functional Endoscopic Sinus Surgery (FESS) to accurately delineate the fine bony details that contribute to disease and also can predispose to complications which can be fatal. 3. MDCT is very useful in predicting the diagnosis of fungal sinusitis by the presence of intrasinus hyperdensity, granulomatous diseases by the presence of nasal septal perforation and intracranial or intraorbital invasion, malignancy by bone destruction and invasion. 4. MDCT can tailor the surgery according to the extent of disease. It helps in determining the prognosis of the malignant tumors depending on the site and extent of the disease. It can also obviate the need for surgery in certain conditions like polyposis. 5. MRI can be problem solving tool in differentiating inflammatory sinonasal diseases from tumors, and also for the presence of intracranial or intraorbital extension. 6. However, MRI alone cannot be performed in the evaluation of paranasal sinus diseases because of the problem of signal voids. It has to be supplemented by CT. 7. MDCT is the preferred initial modality of all imaging studies available because of its ease, availability, accuracy, precision and low cost. 1

The Hope Bill Essay -- essays research papers

The HOPE Bill In the year 2024, the world has grown to increase its size to 24 billion people worldwide. The increase in the population has caused the destruction of most farmland in the world, causing it to look underwater for a supply of food. Private enterprises are currently farming and selling food that comes from underwater regions of the world. However, a vast majority of the world is still not being fed. On a percentage basis, though, we have fewer people unemployed than in 1996. However, that still means that over a hundred million people are unemployed and double that are on welfare or homeless. As a result, I am sponsoring a bill to the senate that will address this problem. The HOPE program, Helping Others acquire Pride and Emancipation, will help the unfortunate people gain pride in what they do. The HOPE will give back the pride that people need and deserve. It will put people into a more productive and rewarding job by emancipating them out of the life each person is leading. Twenty years ago, in the year 2004, the world implemented a youth program that was the exact opposite of Hitler's Youth. For example, the program gives kids a feeling of self-confidence, and they become more tolerant of others and their views. The program places all kids in situations to learn of other cultures and to gain a caring and understanding in all situations, people caring for the plight of others. In the fourth through the sixth grade, all kids are required to complete at least 5 hours of community service each week; in high school, they are required to complete ten hours a week. This program has caused the world to gain a more caring, empathetic attitude towards the well-being of others. "The needs of the many outweigh the needs of the few or the one." This was the groundbreaking program that people had been waiting for so that a program like mine could enter the senate. To solve the problem of the unemployed, the homeless, and the welfare recipients, I will propose a new bill, talk about the arguments against my bill, and present solutions to the arguments. The first part of the plan is to have a world-wide benefit to raise money to help pay for the program. Jerry Lewis raised millions of dollars for muscular dystrophy. In the year 2000, a cure for this debilitating disease was found as a result of these "telethons". People will donate... ... and adding to the budget of the world. As incomes of individuals increase, they will spend more money. Corporations will increase their revenues because of these expenditures. When companies make more money, they have the ability to expand their capacity. Thus, new jobs will be created, jobs that the newly trained and educated workers can fill. In conclusion, the world has had numerous depressions. The most devastating of these were in the 1930's and 2010's. For more than two centuries, the United States has argued and fought over welfare and unemployment. Many people today still want to do away with both programs. We need to remake the Declaration of Independence where all men have certain unalienable rights: life, liberty, and the pursuit of happiness. This bill provides the atmosphere and environment for those less fortunate to pursue these rights. The lagniappe of this bill, the world receives much needed food and gets to encompass additional productive grateful citizens. Look to your heart before you vote on this bill. Only one conclusion is possible: why has it taken us so long to adopt such measures? I thank you for your understanding and sponsorship of this HOPE program.

Aphra Behns Oroonoko †Slaughter of the Human Spirit Essay -- Behn Or

Oroonoko – Slaughter of the Human Spirit   Aphra Behn introduces her characters in Oroonoko as beautiful people who possess a pure, innocent love.   Behn does this in an effort to make her readers feel and question.   Her poetic description of their emotions magnify the horror of the final scene.   Behn's romantic love story is brought to a tragic end through brutality and death.   Why did she choose such an ending?   Her decision to have Oroonoko take the life of his wife and unborn child leaves her audience questioning.   Was what they had love?   If not, what was it?   What had killed their innocence?   Ã‚  Ã‚  Ã‚   The story of Oroonoko and Imoinda began with him approaching her and ended with the cut of his knife.   Oroonoko both began and ended the story that was "theirs."   Therefore, when analyzing their relationship it is most important to examine Oroonoko's behavior.   Oroonoko is the one who determined what path their story would take.   What drove him to end "their" story in such a brutal way?   What caused him to act so uncontrollable?   The truth is that his heart couldn't stand to lose her again.   He couldn't risk not finding her.   He was scared because he realized that he could not protect her.   Even the strong, powerful Oroonoko was not able to rescue her and her unborn child from slavery.   His hope and innocence were killed by fear.   He finally met a force that could beat him.   Ã‚  Ã‚  Ã‚   Throughout the story, Oroonoko exhibits his power and control.   In order to once again prove his courage, Oroonoko goes hunting to kill a tiger that had been too fierce and powerful for others to conquer.   When Oroonoko comes upon the tiger, she is devouring her new kill.   Upon Oroonoko's approach, the tiger stares at him with a "very fierce rag... ...heaven.   This is a beautiful image.   Does it really matter how they chose to exit this world?   The truth is that it does.   Ã‚  Ã‚   Aphra Behn's tale of Oroonoko is not only a tragic love story.   It is also a story about slavery and how it can kill a person.   The relationship between Oroonoko and Imoinda is described as pure and innocent.   Their story compliments the point that Behn was trying to make about slavery.   Slavery can kill hope, purity, and innocence.   Slavery does not only kill the human spirit.   It slaughters it. The student may wish to begin the paper with the following quote: "And these two People represented to me an absolute Idea of the first State of Innocence, before Man knew how to sin."

Weapons of the Middle Ages :: History

Weapons of the Middle Ages Have you ever wondered what kinds of weapons were used in the middle ages? Or have you wondered how they used to slash and bash through the heavily armored knights while being attacked by flying arrows by the longbowman? Well here are the answers There were a wide variety of weapons in the middle ages, one of which was the club. The club was mainly used to crush bones or fracture them. It was made of a light wood with a metal tip on the end and usually had spikes on them to inflict more damage. The club is the first melee weapon ever made and started in the Stone Age to kill deer or wild boar. As ages went by the club became less effective. After about 1400 A.D. the club was very rare to find in battle. What was interesting about the club is that it could easily be changed into a short-handled ax. All they had to do was either cut or take off the tip of the club and attach a sharp blade. The reason they sometimes changed the club into a short-handled ax, was because it could be throw n easily and inflict some pain, where the club when thrown, it was hard to throw and it inflicted little pain and damage. Another very useful weapon was the spear. The spear was a skirmisher’s best friend. A skirmisher was a soldier that carried around a bag full of spears. To keep from giving too much weight, they made the spear for the skirmishers with very lightweight wood, and a small pointy spearhead. The skirmisher’s job was to take the spears and throw them at a long range. The difference between a bow and arrow and a spear was that the spear could easily be turned into a melee weapon. In fact, when a skirmisher had only one spear left, he took the spear, left the bag, and went melee style and went into the battle. The first spear was simply a sharpened rock tied onto a long stick, which was in the Stone Age, and wasn’t used for killing people; it was used to kill animals for food, usually. Probably the most common weapon, was the sword. All kinds of swords, the standard sword, which was just a regular sword, the dagger, or knife, yes it was a type of sword, mainly a backup sword used if a soldier’s weapon was dropped, and the great sword, which was a huge sword that can only be used in control if the soldier used two hands.

Nectar In A Sieve & Don’t Be Afraid Gringo

The relationship between core and periphery nations can be observed by looking at the experiences of the people in the books, â€Å"Nectar In A Sieve† by Kamala Merkandaya and â€Å"Don't Be Afraid Gringo† by Media Benjamin. In both the books Rukmani and Elvia narrate the changes caused by the various stages of capitalism brought by Great Britain in India and by the United States in Honduras respectively. The core periphery relations between these countries lead to many societal problems and these two women deal with these problems, especially the issues pertaining to land and education. In both Rukmani and Elvia's case land was the most important resource required for producing staples, which was used as a source of revenue and food. Education, in this context refers to the level of awareness people had about the influence of core countries on the peripheral nations and how the people viewed this dependency. Rukmani and her family lived under a feudalistic system and the arrival of the British tannery resulted in segregated industrialization in a rice farming village which led to family disintegration, abuse of power and land and to a minor decrease in feudalism. It also led to a shift from peasantry to proletariats. Elvia lived in a semi-feudalistic system in Honduras with highly unequal distribution of land and wealth. The whole of Honduras, including various institutions like the Government and the church were under the influence of the U. S who with their political and economic influence used Honduras for the extraction of resources and also for its own political security in the North American continent. In â€Å"Nectar In A Sieve† Rukmani was married to a tenant farmer called Nathan who worked on rice fields and earned his livelihood by selling his harvest to the landlord. He did not have his own land and so whatever he earned went towards paying for the rent on land. Most of the villagers there, including Nathan were tenant farmers who produced for their own basic needs and not for the market. The village put up a leather tannery in Rukmani's village whose arrival led to segregated industrialization and also to a change in feudalism. Rukmani and the whole village's life were affected, as their village became a â€Å"growing town† (Merkandaya 50) The tannery owners bought the land from the landlords and paid good prices for it. This segregated industrialization weakened the unification of the village and caused great turmoil for everyone, especially Rukmani and her family. It disintegrated her family by creating a need for her sons to go work in the tannery. The expansion of the tannery also led to a loss in user rights as many people, including Rukmani and her family was kicked off the land they used to live on for years, with nowhere to turn to. Thus they were forced to go to an urban city and become proletariats. Arrival of colonialism in the village led to capitalism, while keeping the feudalism intact. Though both systems worked simultaneously, capitalism slowly outdid feudalism as the tannery â€Å"grew and flourished and spread†(51), it got the power and became economically prosperous which allowed the expansion of the tannery. Capitalism in the village changed some of the villagers from peasants to semi proletariats as they started working in the tannery. On the other hand the cost of living went up and so did the level of poverty due to partial urbanization. The tannery extracted the resources using cheap and surplus labor and repatriated the profits for capitalistic accumulation and deprived the village of if. In â€Å"Don't Be Afraid Gringo†, Elvia Alvarado talks about the lives of the â€Å"campesinos† living in Honduras. She was a poor peasant living in a rural village and belonged to a very poor family that could never own land. Most of Elvia's life revolved around social work and helping the fellow campesinos who were facing harsh times due to the influence of the core. Elvia was proactive and resisted to changes brought about by the powerful elite of their society. So her primary job was to recover land which rightfully belonged to the campesinos but was in the hands of a few elite who were using it for their own benefit. Education as described later in the essay created awareness about the injustices done by the powerful elite and helped in her fight for recovering land for the campesinos. The campesinos depended on land, as it was the primary source of food and revenue. Staples produced in Honduras were exported to the U. S markets at very low prices. The U. S had also monopolized capital by bringing technology into Honduras but this was only being used to extract resources. This resulted in unemployment as automated machines as in the case of the banana companies replaced manual labor. Honduras was under a semi feudal mode of production with an unequal distribution of land. Although capitalism was present in urbanized areas, most of the land was under feudal control with peasants fighting for land which was taken away from them. The government did not â€Å"do anything to make the campesino's life any easier. â€Å"(Benjamin 25) The rural areas did not have god transportation and bringing the harvests to the markets was very difficult. Campesinos without land worked â€Å"as day laborers, either for a landowner or for another campesino†(Benjamin 20) for minimal wages. U. S using its influence on the Honduran government and the local elite extracted some precious resources like coal and precious gems and the profits associated with them were never reinvested in Honduras. The U. S also used Honduran land for maintaining regional security. Using Honduras strategic position in Central America, they established military bases and sent troops to Honduras to help government maintain internal control. The societal issue of education brought about by the core periphery relationships in both Rukmani and Elvia's life, in this context deals with the level of awareness both women and their respective societies have about the influence of core nations and their dependence on them. Although Rukmani was semi literate and could read and write, she was not well versed with what was happening around her. She was a very passive resistor and never offered any resistance to the development of capitalism. She foresaw the implications of capitalism by the arrival of the tannery and the dependency associated with it. Therefore she wanted to give all her children education because she knew education was the only thing that could make her children realize the effects of dependence on core. Her suffering along with the suffering of the other villagers shows the lack of awareness they had about the harmful effects of the British colonization. Elvia only received proper schooling till the second grade and so she was basically illiterate but she always had the inclination to learn. As she grew up, she became aware of the harmful effects of Hondurans' dependency on the U. S and how capitalism from the part of the U. S in Honduras was robbing the resources out of Honduras. Although she never had proper schooling, the eagerness to learn about the current affairs made her more and more inquisitive. Elvia took some courses with the church and then started working as a social worker that traveled to different places and created awareness about general issues pertaining to their lives and society. She also took some courses from the Agrarian Reform Institute, which greatly improved her writing skills. Later on in her life, when the church also influenced by the Honduran government that was under the influence of the U. S reduced the support to her group, she became independent and began educating and organizing the campesinos to fight for their rights. She began recovering land that belonged to the campesinos but was in the hands of the elite. Her knowledge of the Agrarian Reform Laws helped her fight with the government for the injustices done to the campesinos. She was thus able to recognize monopoly capitalism by the U. S as being the cause of poverty in Honduras.
