Ethnomedicine Essay Example for Free

Ethnomedicine Essay Since the beginning of man, there have been ailments that have plagued the human race without concern of who it is inflicting or why they occur. These ailments had to have been combated by some sort of medicine by each culture and their remedies must have been plenty. The plethora of different kinds of medicines and remedies to these ailments among the different kinds of cultures is what we, Team Bloodnut, define as ethnomedicine. Many cultures throughout the world practice some form of ethnomedicine. A field of anthropological research, ethnomedicine seeks to describe the medical systems and practices utilized in different cultures. It examines the origins of what people believe cause illness, as well as examine the ways in which individual cultures treat such maladies. Team Bloodnut wanted to discover the healing beliefs and practices held by Amazonian shamans. Through the use of a life history interview, we sought to understand the traditions held by a people through the experiences of a man working with a former shaman of the tribe. Team Bloodnut formed a hypothesis regarding ethnomedicine in today’s modern world. We hypothesized that the remedies and medicines indigenous cultures use to heal the ill are unorthodox from the stand point of western civilization. Western society will view these remedies as barbarian and a total fallacy. We conducted our research through a life history interview, contacting a filmmaker named Matthew Vincent. Possessing an interest in natural medicines, Vincent spent over half a year living in Peru documenting the experiences of an American Shaman’s journey into the depths of Amazonian Shamanism. Together, they discovered the origins and methods involved in practicing shamanism in relation to this particular cultural group. Matthew trained under the ‘gringo shaman’ Ron Wheelock, learning the techniques and methods required to effectively heal members of the community in which they lived. In order to effectively film his documentary in a realistic manner, Matthew Vincent needed to integrate himself into the rituals, learning their practices and lifestyles. Researching through a life history interview best utilized our information since it enabled us to capture the personal experience of a man submerging himself into such a specific aspect of a community’s life. Our group set out to understand the origins of Amazonian shamanism. We wished to learn about the beliefs of the roots of illnesses as well as the methods used to treat them. Ethnomedicine seeks to understand what illnesses mean within a culture and how to remedy these ailments. According to Vincent, shamans believe people contract illnesses due to a variety of reasons. Culturally, the soul brings balance to the physical body and makes it strong. If presumed damaged or corrupt by devious spirits, souls must undergo ritualistic healing in order to return to a healthy state. Physical illness is thought to be a manifestation of corruption within the soul. In order to correct this corruption, patients go through a mixture of ritualistic songs, plant gnosis, and trances. Shamans utilize trances in order to enter different states of consciousness, allowing them to interact with souls and spirits to perform healing to the soul and bring the spirits back to the sick physical body. One extremely common way to remedy an ailment in Amazonian Shamanism is through the use of ayahuasca. Ayahuasca is an extremely hallucinogenic vine used in brews that are consumed by the Shaman along with the patient so the Shaman can conjure the spirits of the plants used in the brew to foresee any future ailments, cure any immediate ones, and try to prevent any others from manifesting themselves within the patient’s body and or soul. The ayahuasca brew can take any time from a couple of hours to brew, all the way to up to two days, being cooked three times. Wheelock told Vincent that he has treated people who have visited a psychiatrist for over a year and with one ayahuasca ceremony, the patient feels more rejuvenated and alive than ever before. Ayahuasca can also be used for other uses as well, depending on the ingredients used in the brew. For example, if brewed with shapishico, moonshine, and rainwater, and left to sit together for about nine days, this brew acts as an extremely potent aphrodisiac. Shamans are not only medicine men, but spiritual guides. Shamans can choose from two different paths when immersing themselves in their practices. They can choose to be curandero or a brujo. A curandero is a healer. He is the medicine man that can heal physical and psychological ailments that one might have. He does this through plant gnosis and conjuring the spirits of the plants to help cure the patient. A brujo, on the other hand, focuses on the dark arts of Shamanism, although he can also heal. In a Shamans training, they are visited by spirits and are given magical darts. These magical darts are a brujo’s weapon of choice when it comes to causing harm or kill another. He can use those towards anybody in the world as long as he has their name, a mental image of the person, a picture, or some sort of memorabilia that depicts who their target is. A curandero will only use these magical darts, usually, to defend himself. When a curandero sends a magical dart to a brujo, it’s usually with the intention to kill him. After conducting our life history interview, Team Bloodnut came to a conclusion on our hypothesis. We concluded that our hypothesis was correct regarding the differences between western medicines and Amazonian Shamanistic medicines. Western medicines include all of the technologies, modern medicines, and commodities that these indigenous cultures do not have access to; therefore we are much more technologically advanced. These countries are at a disadvantage when it comes to the commodities and technologies but that doesn’t mean that the quality is any less. These medicine men spend most of their lives learning how to conjure and interact with these spirits of nature so that they can heal in their favor. The way in which they do so shouldn’t be frowned upon. If these Shamans have found ways to cure, not just treat these illnesses and ailments, then why haven’t we, Western Civilization, adopted these methods? Is it the fear or the skepticism of failure? We think that it’s not so simple. We believe that the reason for these medicines not being accepted into our country is simply so the government won’t lose money and control. Wheelock cured a patient that had been visiting a shrink for over a year. In that time how much money did that psychiatrist earn? From that income how much did the government take from the psychiatrist in taxes? This is only for one person, too. Some people spend half of their lives, if not longer visiting some kind of medical practitioner or some form of psychedelic help. There will never be a shortage of sick people, so if they are simply just cured with a couple of ayahuasca ceremonies, that’s a pretty significant chunk out of the United States’ money supply. Not only is it a monetary issue, but also a control issue. If these practices were administered in the United States, people would gain insight and enlightenment to its effects. There is a chemical in ayahuasca that is an intense psychedelic. Dimethyltryptamine is the psychedelic in the ayahuasca that puts the body in the state in which it can be visited by manifesting spirits of the vine. If this psychedelic were to fall into the wrong hands, it could be very harmful to not only to America’s economy, but also to the ones who abuse it. Ergo, ethnomedicine is a sensitive subject because it is not only a way to treat people within a certain country or tribe, but it is also the way of life and the way generations upon generations have practiced these remedies. Just because different cultures do things differently, it doesn’t mean that one way is right and the other is wrong. If we, as a species and inhabitants of this Earth, all worked together and shared our practices with each other in the field of medicine, maybe we could find cures, not just treatments to malignant diseases such as cancer. Ayahuasca ceremonies are not just a ritual to heal patients that come to Shamans, but also a lifestyle.

COBOL :: Essays Papers

COBOL In the summer of 1998, St Louis Public Schools ( SLPS ) chose to convert form it's IBM System/390 mainframe to a client server environment. Not only was the SLPS affected but the Public School Retirement System ( PSRS ) was also affected since they use their mainframe system. PSRS started looking for a solution for their processing requirements. They were debating on weather to obtain an existing package to replace their system If they did would the be able to convert it to support how they run their business, or would they have to change how they conduct business to match the new software. They were also confused as to what new equipment might have to be purchased since they currently were running on older standalone workstations without a server. The organization decided to purchase new workstations, a server, a high-speed networked laser printer and Windows/2000 workstation and server components. Due to the organizations small size they elected to hire two contract software engineers to assist in the conversion, as well as process year end systems. The company also had to select a programming language, they decided on COBOL, the SLPS had a free copy of Micro Focus Net Express COBOL called the University Edition. It is available for schools to utilize in a classroom situation. The software was reviewed, it was decided that it would be adequate for their needs. It had features necessary to satisfy the requirements. Net Express is a Windows based product that is extremely powerful. That mainframe COBOL code formed the basis of the conversion, The conversion consisted mostly of modifying select statements, CICS code, some program calls to mainframe support routines, 'compare' statements also had to be checked for sequence problems ensuring that a mainframe 'if' statements of 'equal to' or 'greater than' were still valid for an ASCII based environment. The company found Downloading software and data files from the mainframe relatively easy, they used a mainframe access program called â€Å"Extra!† Packed fields were unpacked on the mainframe, downloaded to the server, and repacked if necessary. After the conversion took place the next task was to conduct year-end processing. This involved many tasks for the organizations, including; closing out of last year's business, income tax, providing information to our retirees, allowing for Open Enrollment for various insurance plans, and providing data to our actuarial firm to assist in funding and benefit decisions.

Super Resolution Mapping To Determine Shoreline Position Environmental Sciences Essay

Coastal zone and shoreline monitoring is an of import undertaking in sustainable development and environmental protection. For coastal zone monitoring, shoreline extraction in different times is a cardinal work. Features of H2O, flora and dirt make the usage of the images that contain seeable and infrared sets widely used for coastline function Conventionally, photogrammetric technique is employed to map the tide-coordinated shoreline from the aerial exposure that are taken when the H2O degree reaches the coveted degree. On site study taken at these H2O degrees are more expensive to obtain than distant feeling imagination. With the development of distant feeling engineering, orbiters can capture high-resolution imagination with the capableness of bring forthing shoreline place. In recent old ages, satellite remote feeling information has been used in automatic or semi- automatic shoreline extraction and function. Braud and Feng ( 1998 ) evaluated threshold degree slice and multi-spectral image categorization techniques for sensing and word picture of the Louisiana shoreline from 30 m spacial declaration Landsat Thematic Mapper ( TM ) imagination. They found that thresholding TM Band 5 was the most dependable methodological analysis. Frazier and Page ( 2000 ) quantitatively analyzed the categorization truth of H2O organic structure sensing and word picture from Landsat TM informations in the Wagga part in Australia. Their experiments indicated that the denseness slice of TM Band 5 achieved an overall truth of 96.9 per centum, which is every bit successful as the 6-band maximal likeliness categorization. Besides multi-spectral orbiter imagination, SAR imagination has besides been used to pull out shorelines at assorted geographic locations ( Niedermeier, et A l. 2000 ; Schw & A ; auml ; bisch et Al. 2001 ) . While the really all right spacial declaration detectors ( e.g. IKONOS ) offers increased spacial declaration, the imagination from such systems is frequently inappropriate for many users, peculiarly if a big country is to be mapped ( Mumby and Edwards, 2002 ) . Therefore, if constrained to utilize fine-to-moderate spacial declaration ( 0.10 m ) imagination, there is a desire to map the water line at a subpixel graduated table. In such state of affairss the purpose is, hence, to deduce a map that depicts the characteristic of involvement at a graduated table finer than the informations set from which it was derived, which may be achieved through a super-resolution analysis ( Tatem et al. 2001, Verhoeye and De Wulf 2002 ) . 3.2 Test site The work focused on a 38 kilometer stretch of along a seashore off the North West Cape in the north west seashore of Western Australia ( Figure 3.1 ) . The shoreline was characterized by different beaches such as flaxen beaches, muddy and drop and facing to the Exmouth Gulf in the Indian Ocean. Exmouth Gulf is really shallow, with an mean deepness of about 10 m and northerly confronting drowned river vale in northwest Australia reverse estuarine embayment on the northwest shelf of Australia. The tidal scope is less than 2 m and varies little between neap and spring tides. The Exmouth part is exposed to preponderantly south to southeasterly air currents throughout the twelvemonth ( Bureau of Meteorology, 1988 ; Lough, J.M. , 1998. Coastal clime of northwest Australia and comparings with the Great Barrier Reef: 1960 to 1992. Coral Reefs 17, pp. 351-367. Full Text via CrossRef | View Record in Scopus | Cited By in Scopus ( 10 ) Lough, 1998 ) . During spring and summer by and large moderate ( 21-30 kilometers per hour ) southward winds dominate, and fall and winter records show by and large lighter ( 11-20 kilometers per hour ) air current velocities with fluctuations between the dominant sou'-east air current and north to northeast air currents. The air current government is controlled chiefly by the interplay of the southeasterly trade air current system and the west coast-generated sea zephyr, in concurrence with a local sea zephyr developed within the Gulf. australia1-edit.JPG Figure 3.1: Location of shoreline trial site ( shaded ) and selected as had scope of morphologies in a survey country. 3.3 Data sets The survey used a series of harsh spacial declaration National Oceanic and Atmospheric Administration ( NOAA ) images over survey site to bring forth a ace declaration image. For this survey, the shoreline was defined as the place of the boundary between H2O and land at the clip satellite imagery acquisition. The NOAA series of orbiters which each carry the Advanced Very High Resolution Radiometer ( AVHRR ) detector. These detectors collect planetary information on a day-to-day footing for a assortment of land, ocean, and atmospheric applications. Specific applications include forest fire sensing, flora analysis, weather analysis and prediction, climate research and anticipation, planetary sea surface temperature measurings, ocean kineticss research and hunt and deliverance ( CCRS, 1998 ) . 3.3.1 AVHRR detector features AVHRR informations set is comprised of informations collected by the AVHRR detector and held in the archives of the Geoscience Australia. Carried aboard the National Oceanic and Atmospheric Administration`s ( NOAA ) Polar Orbiting Environmental Satellite series, the AVHRR detector is a broad-band, 4- or 5-channel scanning radiometer, feeling in the seeable, near-infrared, in-between infrared and thermic infrared parts of the electromagnetic spectrum. It provides planetary on board aggregation of informations over a 2399 kilometer swath. The detector orbits the Earth 14 times each twenty-four hours from an height of 833 kilometer. In this survey, NOAA images acquired from Geoscience Australia and NOAA antenna in Alice Springs permits acquisition of twenty-four hours and night-time base on ballss. There are usually about two day-time base on ballss per orbiter and two night-time base on ballss per orbiter. The detector parametric quantities as shown Table 3.1. Merely informations acqui red in Channel 2 ( 0.725 – 1.00 Â µm ) was used for this survey because land H2O boundaries clearly seen on the image. Table 3.2 shows an AVHRR Spectral Characteristics.

The Landsat way was 115 and WRS Row 075 were geometrically corrected and georeferenced to WGS 84 ( universe co-ordinate system ) .o Georeference imagination is defined imagination which has been corrected to take geometric mistakes and transformed to a map projection. Georeferenced image rectification can take one of the two signifiers, systematic and preciseness. Systematic rectification involves utilizing orbital theoretical accounts of the orbiter plus telemetry informations to happen the approximate relationship between the image and the map coordinates. Precision rectification uses land control points to register the image to absolute geographical co-ordinates. In other words, in a geo-referenced image the pels and lines are non aligned to the map projection grid geo-referenced image the pels and lines are non aligned to the map projection grid . A Landsat 5 TM scene has an instantaneous field of position ( IFOV ) of 30 m by 30 m ( 900 square metres ) in bands 1 through 5 and band 7, and an IFOV of 120 m by 120 m ( 14,400 square metres ) on the land in set 6. Merely band 4 ( 0.76 – 0.90 Â µm ) was used for delineate a shoreline. landsat1.JPG Figure 3.2: Landsat 5 TM informations over study country. Acquired day of the month: 24 August 2007 3.4 Method In the context of ace declaration techniques, it is assumed that several harsh spacial images can be combined into a individual all right spacial image to increase the spacial declaration content. The harsh spacial images can non all be indistinguishable and there must be some fluctuation between them, such as translational gesture analogue to the image plane ( most common ) , some other type of gesture ( rotary motion, traveling off or toward the camera ) , or different screening angles. In general, ace declaration can be broken down into two wide parts: I ) enrollment of the alterations between the harsh spacial images, and two ) Restoration, or synthesis, of the harsh spacial images into a all right spacial image ; this is a conceptual categorization merely, as sometimes the two stairss are performed at the same time. In this survey, the aim is to bring forth all right spacial declaration image from multiple harsh declaration images. Fine spacial declaration image has been applied with object designation methods which may build with regard to image enrollment and super-resolution building. All parametric quantities are used iteratively and do object designation secured from mistake response and been processed in hardiness, accurate and preciseness manner. 3.4.1. Image Registration Image enrollment is the procedure of covering two or more images of the same scene taken at different times, from different point of views or by different detectors. Image enrollment is a important measure in all image analysis undertakings in which the concluding information is gained from the combination of assorted informations beginnings like in image merger. Image enrollment consists of following four measure ; characteristic sensing, characteristic matching, transform theoretical account appraisal and image resampling and transmutation. i. Geometric Registration The geometric deformations present in airborne remotely perceived images may be categorized into system-independent and system-dependent deformations. The system independent deformations are caused by the gesture of the detector and by surface alleviation. Figure 3.3 shows on instance of images which are related by a planar projective transmutation or alleged planar homography. There are two different state of affairss where ( a ) images of a plane viewed under arbitrary camera gesture and ( B ) image of an arbitrary 3D scene viewed by a camera revolving about its ocular Centre or zooming. Figure 3.3: Two imaging scenarios for which the image-to-image correspondence is captured by a planar homography ( Capel and Zimmerman, 2003 ) Under a planar homography, points are mapped as: ten ‘ = Hx, where ten ‘ correspondence point of mention points x in other image and H is a 9 transmutations projection. The different of planar homography based on transmutation matrix attack below: or equivalently ; ( 3.1 ) ten ‘ = Hx The tantamount non-homogeneous relationship is ( 3.2 ) The scenario depicts in which homography will happen when a freely traveling camera views a really distant scene, such instance in airborne remote sansing ( Forte and Jones, 1999 ) . ( two ) Photometric Registration Photometric enrollment refers to the process by which planetary photometric transmutations between images are estimated. This enrollment traveling to use a theoretical account which allows for an affine transmutation ( contrast and brightness ) per RGB shows below. 3.3formula3.GIF Where, r1, g1, b1 are RGB channel in image 1 while r2, g2, b2 indicate RGB channel in image 2. Matrix A is used to calculate the remainder of brightness and contrast ? . Image enrollment of homography image concludes in Figure 3.4, last two stairss iterate until the figure of itelaration is stable. method.GIF Figure 3.4: Procedure to gauge a homography between two images. In order to deduce ace declaration image utilizing multiple series of low declaration images, all images need to register at the same time and corrections may easy implemented. Block bundle accommodation traveling to be considered as the best calculator to calculate all braces of back-to-back frames in the input sequence. Parameters such as interlingual renditions, rotary motions, graduated table, contrast and brightness, characteristic base enrollment, RANSAC ( RANdom SAmple Consensus ) and fiting could be done at the same time in every image brace. Generative image formation theoretical account is the best image formation algorithms which may see geometric transmutation of n images, point spread map which uniting effects of optical fuzz and gesture fuzz, down-sampling operator by a factor S where trying rate traveling to be entree, scalar light parametric quantities and observation noise. This theoretical account is generalized as follows: formula4.GIF f = mulct spacial declaration image gn = nth observed harsh spacial declaration image ?n = geometric transmutation of n-th image H = point dispersed map sv = down-sampling operator by a factor S ?n, ?n = scalar light parametric quantities ?n = observation noise 3.5 Hard categorization To distinguish between land and H2O organic structure a difficult classifier was applied to the fake coarse spacial declaration orbiter detector imagination. The maximal likeliness difficult classifier used to sort the harsh spacial declaration imagination ( NOAA AVHRR ) . The same preparation sites used in sorting the all right spacial declaration image ( cite informations ) were used ( Figure 4.5 ) . Using these developing sets the 20 m imagination was classified to 2 categories ( land and H2O ) . The resulting image ( Figure 3.7 ) would subsequently be analysed to find the positional mistake between the predicted shoreline location and the existent location based on the land informations. densitynooa.jpg ( a ) densitylandsat.jpg ( B ) Figure 3.5: ( a ) 1100 m spacial declaration and ( B ) 30 thousand spacial declaration classified imagination 3.7 Soft Categorization Difficult categorization techniques have been popular in distant feeling but they merely assign one category to a certain pel ( Jensen, 1996 ) . As shoreline pels normally contain a mixture of land and H2O categories, information within a pel is lost. A major job for accurate reading of distant feeling informations is related to the fact that pels may incorporate more than 2 categories which would merely be realised from land activities ( Foody, 1992. To turn to this job research workers have developed methods to deduce estimations of the sub-pixel category composing through the usage of techniques such as mixture modeling and soft or fuzzed categorizations ( Foody, 1996 ) . Soft classifiers allow pels to hold variable grades of rank to multiple categories. Soft classifiers assign a rank class between 0 and 1 to each category in a pel. This allows a pel to be associated to multiple categories instead than merely to one category as in conventional difficult classifiers. The end product of the soft categorization for each pel was an indicant of the comparative rank to the two categories and, in the country where rank was greatly assorted, this was taken as an estimation of the relative screen of the constituent categories ( figure 3 ) . noaa.jpglegend.GIF Figure 3.6: End product of soft categorization. The gray graduated table indicates the grade of rank to the land category. 3.8 Super declaration Maping The water line was mapped from the ace declaration image generate from the series of harsh spacial declaration image.. The same preparation sites were used in all the categorizations. As a benchmark, a conventional difficult categorization was used to foretell the water line from the fake image. The water line was fitted to the derived end product of this categorization by weaving it between pels allocated to the different categories. sr.JPG ( a ) density_sr.JPG ( B ) sr.JPG ( degree Celsius ) Figure 3.7: Ace declaration technique ( a ) individual image ( B ) difficult categorization of ace declaration image ( degree Celsius ) water line word picture. 3.tif ( a ) 5.tif ( B ) 12a.tif ( degree Celsius ) 15a.tif ( vitamin D ) 20.tif ( vitamin E ) 20.tif ( degree Fahrenheit ) Figure 3.8: End product of ace declaration technique ( a ) 3 images ( B ) 5 images ( degree Celsius ) 12 images ( vitamin D ) 15 images ( vitamin E ) 30 images ( degree Fahrenheit ) 50 images. 3.8 Positional Error Analysis End product from a difficult and soft categorization produces images with pels values stand foring the proportion of a certain category within pels. But it does non bespeak where within a pel these categories are located. To turn to this job, methods of administering the proportion within each pel to different categories were explored. The truth of shoreline maps generated at each spacial declaration from application of the difficult categorization, soft categorization and ace declaration method from multiple images were analysed for survey country ( Figure 3.1 ) . For each infusion and coarse-spatial declaration image, the truth of the shoreline anticipation derived was determined by comparing the to the Landsat 5 TM informations for every meter of the shoreline ( Table 3.3 ) The positional truth along the 38km length of shoreline in each infusion is shown in Table 3.3: Positional truth of the each method.
