Acclimation in a Changing World essays

Acclimation in a Changing World essays Amidst the thin air and harsh conditions that one would find in the Himalayas, lives a hard working group of people called the Sherha (or Sherpa). Many view the Sherpa as the workhorses behind reaching the worlds highest summits. While they are among the most trusted guides in the Himalayas, the Sherpa culture dates back hundreds of years to a time of subsistence agriculture and intra-regional trade. Slowly, their society is becoming more and more integrated with western ideas and culture, as most isolated peoples have experienced over time. They have transformed into a society thriving on tourism, rather than trade and agriculture. Such a transformation is necessary for any culture to survive. The ancestors of the Sherha most likely migrated from the Kham, in eastern Tibet over 500 years ago, in search of pastures more suited for their hunting and agricultural needs. The Sherha were a typical hunter/gatherer society, specializing in the herding of yaks, and the growing of rice, corn, and potatoes (beginning in the 1850s) (History of the Sherpas: A Chronological Chart). Their existence depended upon trade between the clans, and other ethnic groups, however. While there was much equality between women and men, there was clear division of labor between the two groups. The men, for example, were the caretakers of the yaks, while the women were involved in the agriculture and trade aspects. With such isolation that the Himalayas provide, economic opportunities offer little more than a subsistence way of life, with a limited trade. The Sherpa are, to this day, raised in a harsh environment, learning at an early age to provide for their respective clans. This loyalty i s the driving force behind why the society has strived for hundreds of years, with little change. Kinship in the Sherpa culture is one of patrilineal descent, with each clan being traced back hundreds of years through the 18 different clans, or f...

Thermal Pollution Essay Example

Thermal Pollution Essay Example Thermal Pollution Paper Thermal Pollution Paper Individual Episcopal Institute of Management (MM) hereby declare that this report as a part of the course ?Contemporary Issues in Management (MBA 805. 1 ) is the result of my own work. I also acknowledge the other works / publications cited in the report. (Signature) Place: Change Date: 17. 06. 2013 (Name of the student) 2 BRIEF OF TOPIC Thermal Pollution may be defined as the excessive raising or lowering of water temperature above or below normal seasonal ranges in streams, lakes, or estuaries or oceans as the result of discharge of hot or cold effluents into such water. Thermal Pollution is harmful because its increase water temperature in streams, rivers, lakes, or occasionally, coastal ocean waters. Thermal pollution is caused by either dumping hot water from factories and power plants or removing trees and vegetation that shade streams, permitting sunlight to raise the temperature of these waters. Like other forms of water pollution, thermal pollution is widespread, affecting many lakes and vast numbers of streams and rivers in the United States and other parts of the world. A temperature increase as small as 1 or 2 Celsius degrees (about 2 to 4 Fahrenheit degrees) can kill native fish and plants or drive them out in favor of other species, often with undesirable effects. CLC Control of Thermal Pollution CLC Effects of Thermal Pollution CLC Sources of Thermal Pollution CLC OBJECTIVE C] To know what is Thermal pollution To identified reason of Thermal Pollution and its sources 0 To measurement effect of Thermal Pollution on environment. CA To find effective control tools and Step for decrease Thermal pollution. 3 DATA ANALYSIS AND INTERPRETATION In India, about 75 to 82 percent of thermal pollution is generated by power plants. The remainder is from industrial sources such as petroleum refineries, pulp and paper mills, chemical plants, steel mills and smelters. This study is based on global monthly temperature data, from 1880 until today (NOAA NCSC, 2001). These temperatures are separated into land area tem- premature (LA T), sea surface temperature (SST), and a combined global mean temperature (MEAN). MEAN is calculated by area weights corresponding to the global sea area (71 %) and land area (29%). During the year, SST is rather constant while the LAT varies considerably. CAT is about 3 ? 12 j lower than SST during the year. Fig. Indicates the LAT increase since 1880 to be 1. 2 j (to 9. 3 j) while the SST increase is 0. 5 j (to 16. 4 j). The corresponding combined global mean temperature has increased boy. 7 j (to 14. 3 j). Before that, during the years 1856 1880, the global mean temperatures were al- most constant (Jones et 2001 In water above 1400 F (600 C) it is very unusual for algae or bacteria to live, and serious problems occur at even much lower temperature levels. Unlike warm-blooded animals, fish and other cold-blooded organisms do not have a regulatory mechanism for maintaining a fixed internal body temperature. Therefore when water temperature changes, the body temperatures of the organisms also change. The resulting thermal stress may be lethal to some species. Factors such as diet, age, previous temperature exposure, weather, season of the year, and chemical composition of the water may change the specific lethal temperature point for fishes. Gender certain conditions, for example, brown trout cannot live in water at a temperature above 790 F (260 C). However, some hardy fish, often known as ?rough fish, can survive in even higher temperatures?carp, for example, can live at 950 F (350 C) water temperature. 4 Even comparatively small temperature increases may have serious results, affecting for example, reproduction in aquatic organisms. For example, the natural rise in water temperature during the spring causes female oysters and clams to shed their eggs. A similar, but artificially produced, temperature rise at a different time of the year can trigger the release of immature eggs. Excessive temperature can also prevent the normal development of certain eggs. Increased temperature may also affect hatching time in certain species. For example, herring eggs normally hatch in 47 days at a temperature of 320 F (0. 0 C). When the Water temperature is raised to 580 (14. ICC) the eggs hatch in 8 days. Such an early hatching often results in smaller adult size and shortened life span. Small water-temperature increases may increase the level of activity of certain organisms, whereas higher temperatures tend to decrease the level of activity. Lake trout, for example, cruise more rapidly as the temperature nears 610 (160 C) but then slow down above that temperature. A water temperature of 750 F (240 C) is lethal for them. As the fishs level of activity decreases so does its ability to catch food. 5 ARTICLE 1 Sources of Thermal Pollution Thermal pollution may be caused by four major sources. They are A) Water as a cooling agent. B) Soil erosion, C) Deforestation of shorelines, and D) Run-off from hot paved surfaces. A) Water as a cooling agent: It is the major source of thermal pollution of water in most part of the world. The use of water as a cooling agent in power plants and factories and industrial facilities causes thermal pollution. B) Soil erosion: Soil erosion makes the water muddy, which in turn increases the absorption of light, thus increasing the water temperature. C) Deforestation of shorelines: This contributes to the problem of thermal elution in two ways. First the plant roots hold soil particles together. Hence the deforestation results erosion of soil particles. Secondly, vegetation provides shade to the water surface. Deforestation increases the amount of light hitting the water surface, thereby raising the water temperature. D) Run- off on hot surface: Storm water runoff on warmed urban surfaces, such as streets, 6 sidewalks and parking lots causes raising of the temperature water that flows on the surface Effects of Thermal Pollution Thermal Pollution increased the temperature of water considerably. This increase in temperature causes the following effects. A) Change in water properties: Temperature affects physical, biological and chemical parameters in a water body B) Disturbed Ecosystem: Most aquatic organisms have adapted to survive within a range of water temperatures. Some organisms like trout and strongly nymphs prefer cooler water, while others such as carp and dragonfly nymphs thrive under warmer conditions. As the temperature of river or lake increases, cool water species will be replaced by warm organisms. Few organisms can survive in temperatures of extreme heat or cold. C) Reduced dissolved oxygen: The addition of heat reduces the waters ability o hold dissolved gases, including the oxygen required for aquatic life. Fifth water temperature in greater than 95 degree Fahrenheit the dissolved oxygen content may be too low to support some species. D) Increased bacterial growth: Warmer water allows bacterial populations to increase and thrive and algae blooms may occur. E) Photosynthesis: The rate of photosynthesis by algae and larger aquatic plants is also affected by thermal pollution. F) Thermal shock: When a power plant first opens or shut down for repair, fish and other organisms adapted to a particular temperature range can be ailed by the abrupt change in water temperature. This is called as thermal shock. 7 G) Increase in toxicity: The rising temperature increases toxicity of the chemicals present in water causes massive morality of fishes. Control of Thermal Pollution Following are some of the preventive measures of thermal pollution. A) Temperature of water can be reduced by taking the water to wet or dry cooling towers which are being used to pre cool that water before discharge transfers the heat from the water to the atmosphere. 8) Discharging the heated water into shallow ponds or canal, allowing it to cool, and reusing it as cooling Water. C) The thermal discharge from an industry can also be used in heating homes, building or other such structures. This is achieved by circulating the hot water through pipes in the structures. D) Water with temperature can be successfully used in aquaculture. E) The heated water can also be used in agriculture, especially for frost protection during the cold seasons. 8 ARTICLE 2 INTRODUCTION Thermal Pollution, harmful increase in water temperature in streams, rivers, lakes, or occasionally, coastal ocean waters. Thermal pollution is caused by either dumping hot water from factories and power plants or removing trees ND vegetation that shade streams, permitting sunlight to raise the temperature of these waters. Like other forms of water pollution, thermal pollution is widespread, affecting many lakes and vast numbers of streams and rivers in the India and other parts of the world. A temperature increase as small as 1 or 2 Celsius degrees (about 2 to 4 Fahrenheit degrees) can kill native fish, shellfish, and plants, or drive them out in favor of other species, often with undesirable effects. MAJOR SOURCES The major sources of thermal pollution are electric power plants and industrial factories. In most electric power plants, heat is produced when coal, IL, or natural gas is burned or nuclear fuels undergo fission to release huge amounts of energy. This heat turns water to steam, which in turn spins turbines to produce electricity. After doing its work, the spent steam must be cooled and condensed back into water. To condense the steam, cool water is brought into the plant and circulated next to the hot steam. In this process, the water used for cooling warms 5 to 10 Celsius degrees (9 to 18 Fahrenheit degrees), after which it may be dumped back into the lake, river, or ocean from which it came. Similarly, factories contribute to thermal pollution when hey dump water used to cool their machinery. The second type of thermal pollution is much more widespread. Streams and small lakes are 9 naturally kept cool by trees and other tall plants that block sunlight. People often remove this shading vegetation in order to harvest the wood in the trees, to make room for crops, or to construct buildings, roads, and other structures. Left unshaved, the water warms by as much as 10 Celsius degrees (18 Fahrenheit degrees). In a similar manner, grazing sheep and cattle can strip streamside of low vegetation, including young trees. Even the removal f vegetation far away from a stream or lake can contribute to thermal pollution by speeding up the erosion of soil into the water, making it muddy. Muddy water absorbs more energy from the sun than clear water does, resulting in further heating. Finally, water running off of artificial surfaces, such as streets, parking lots, and roofs, is warmer than water running off vegetated land and, thus, contributes to thermal pollution. IMPACTS All plant and animal species that live in water are adapted to temperatures within a certain range. When water in an area warms more than they can tolerate, species that cannot move, such as rooted plants and hellish, will die. Species that can move, such as fish, will leave the area in search of cooler conditions, and they will die if they can not find them. Typically, other species, often less desirable, will move into the area to fill the vacancy. In general, cold waters are better habitat for plants and animals than warm ones because cold waters contain more dissolved oxygen. Many freshwater fish species that are valued for sport and food, especially trout and salmon, do poorly in warm water. Some organisms do thrive in warm water, often with undesirable effects. Algae and other plants grow more rapidly in warm eater than in cold, but they also die more rapidly; the bacteria that decompose their dead tissue use up oxygen, further reducing the amount available for animals. The dead and decaying algae make the water look, taste, and smell unpleasant 10 CONTROLS Thermal pollution from power plants and factories is relatively easy to control. Instead of discharging heated water into lakes and streams, power plants and factories can pass the heated water through cooling towers or cooling ponds, where evaporation cools the water before it is discharged. Alternatively, power plants can be designed or refitted to be more efficient ND to produce less waste heat in the first place. In a process called generation, the excess heat energy from generating electricity can be used in another manufacturing process that needs such energy. Where homes or other buildings are located near industrial plants, waste hot water can be used for heating?an arrangement often found in Scandinavian towns and cities, and proposed for use in China. In the United States, the problem of industrial thermal pollution was first addressed in 1970, when Congress gave the Atomic Energy Commission authority to regulate thermal pollution from nuclear power plants. In 1 972, the comprehensive Clean Water Act instructed the Environmental Protection Agency to issue regulations to clean up all hot water discharges from all power plants, nuclear or conventional. Since then, thermal pollution from power plants has not been a major issue in the United States. To prevent thermal pollution due to deviation, the prescription is simple: do not devastate. Landowners can leave strips of trees and vegetation along streams and shorelines. Grazing livestock can be kept away from streamside by fencing. All efforts to control erosion also have the effect of keeping water clearer and, thus, cooler. As a practical matter, however, thermal pollution from deviation is quite hard to control because it is caused by the cumulative effect of many peoples actions, most of which are individually minor. Regulations focus on a few of the most important threats. Grazing 1 1 management plans, for instance, are intended to counter thermal pollution and other problems on lands owned by the federal government. In the United States, regulations governing logging on both public and private lands supposedly protect streamside, though enforcement is often lax. Elsewhere, streamside protection is largely up to private landowners, encouraged and died by such advisory organizations as the federal Natural Resources Conservation Service and cooperative Resource Conservation Districts. Solutions Several engineering solutions are available to minimize thermal pollution from major industrial sources. One is a cooling pond into which heated wastewater is released before it enters a natural waterway. The cooling pond permits evaporation of some water, carrying heat into the air and thus releasing cooler water into the waterway. The evaporated water might, however, under some conditions, condense, producing fogs where none existed before. In addition, the evaporation from the cooling pond sight deprive the waterway of significant amounts of water, which could be serious during summer months when the natural flow in a river is low. Another possible solution to the problem of thermal pollution is the cooling tower?either wet or dry?which also transfers heat to the air. In both types, heated water is introduced into a tower through which air is blown, and some heat is passed to the air. In wet towers, water and air are in contact, resulting in water loss. In dry towers, a device like a car radiator carries the heated Water, and less Water is lost. Several suggestions for the beneficial uses Of Herman pollution have been made. Among them is the possible use of heated water under fields to lengthen the growing season for certain crops, under city streets in winter to melt snow, or in cold estuaries areas to increase growth offish and shellfish. At the moment, these schemes are untested on a large scale. All solutions must consider the general health of the environment as well as energy use patterns, overall population growth, and other factors.

How could a company reduce it's high of absenteeism Research Proposal - 1

How could a company reduce it's high of absenteeism - Research Proposal Example Notwithstanding its size, it has been experiencing absenteeism problems. The company was founded in 1930 as American Airways; however the first flights commenced in 1934. American Airlines operates out of four hubs in the USA- one each at JFK, Miami, O’Hare and Los Angeles Airports, while its headquarters remains at Dallas Forth Worth Airport. American Airlines has a fleet of 621 aircraft as of December 2010. Tom Horton is the President and Gerard Arpey is the current CEO. American Airlines is one of the most reputed airlines in the USA. However due to its sheer size, it has had its share of problems. Among these, absenteeism has been reported a key factor affecting its service delivery. Through this project, I seek not only to find the reasons behind this unfortunate circumstance; I also attempt to find the reasons and to try to solve the problem by applying the theories of management and organizational behavior towards this end. I hope I have impressed upon at least some employees the value of honest and true service and the need to cut down absenteeism to the very minimum. 5. What do you think that American Airlines needs to do in order to motivate you and other employees to work more honestly and as a team to improve service levels, efficiency and effectiveness at American Airlines? (Thank you for your support and assistance. I assure you that this information will be kept strictly confidential, and will not be shared with anyone except my class teacher and fellow students for the purpose of my assignment). In addition to talking to people, making observations can be a good source of primary research on a problem. Since I was looking at the causes of absenteeism and wanted to correct the situation, I chose to relax in front of the American Airlines Customer Service Counter one afternoon and observe service attitudes in action. 3. Morale and work attitude determined through demeanor, conduct with passengers, willing to hear them out

Neonatal Intensive Care Essay Example | Topics and Well Written Essays - 4000 words

Neonatal Intensive Care - Essay Example Heat may be lost by water evaporation from the skin of the infant, and this is especially likely immediately after delivery. Nursing strategies can address each of these mechanisms. Taking the case of healthy term infants, the most suitable ideal strategy would be to wrap the term infant in warm blankets and to place them into the mothers' arms. The neonate should be dried completely to prevent evaporative heat loss. The neonate can be placed in a preheated radiant warmer immediately after delivery. A water impervious blanket can prevent evaporative heat loss. Cold oxygen from mask blowing over the neonate's skin should be prevented. Once stabilized, the neonate should be transferred to convection warmed incubator since radiant warmer cannot prevent convection heat loss (Sauer PJJ et al., 1984). Most preterm infants usually present with typical signs and symptoms of respiratory distress. These include retractions of the chest, grunting with breathing, rales, rhonchi, nasal flaring, and tachypnoea. Additionally, there may be tachycardia, murmurs, and cyanosis. Most preterm babies demonstrate a central cyanosis with cyanosis of the oral mucous membrane. Congenital heart disease may present with differential cyanosis with respiratory distress. There may be associated hypertension or hypotension. There may be hyperpnoea of deep unlaboured breathing or rapid and shallow breathing. There may be disease specific signs and symptoms. Clinically, the onset of massive pulmonary hemorrhage is heralded by sudden deterioration of the infant with hypotension, pallor, cyanosis, bradycardia, or apnea. Pink or red frothy liquid drains from the mouth. There can be periodic breathing, defined as recurrent sequences of pauses in respiration lasting 5 to 10 seconds followed by 10 to 15 seconds o f rapid respiration. Apnoeic episodes are cessation of respiration for 15 to 20 seconds, frequently complicated by cyanosis, pallor, or bradycardia. Small preterm infants exhibit these systemic responses more readily than do more mature infants, even when the apnea is shorter. Bradycardia can be observed during apnoea (Behrman RE et al., 2002). Causes 1. Respiratory distress syndrome (RDS). 2. Bacterial pneumonia/sepsis 3. Pneumothorax (generally follows initiation of respiratory support, but may occur spontaneously). 4. Pulmonary hemorrhage: more common in preterm infants (specially those with those with respiratory distress syndrome) 5. Congenital pulmonary hypoplasia. Activity 3: Hypoglycaemia in the Newborn Perturbations in glucose metabolism after birth, caused by failure to adapt to the extrauterine environment as a result of either alterations in maternal metabolism or intrinsic metabolic problems in the neonate, often result in hypoglycaemia. Although a consensus regarding cutoff values for hypoglycemia has not been reached, most investigators would consider a plasma glucose concentration of lower than 36 mg/dL to be low when it requires intervention, in a full-term neonate 2 to 3 hours after birth. Care should be taken in interpreting glucose values during the transition period of the first 2 to 3 hours after birth, when the plasma glucose concentration may drop to low levels followed by spontaneous improvement. If low glucose levels are observed during this time, frequent glucose determinations

Referral coursework- Viva Alterative Coursework

Referral - Viva Alterative - Coursework Example hers had highlighted a possible relationship existing between the ecological characteristics of the Canary Islands and the morphological characteristics exhibited by the Chalcides lizard. Such previous researches have associated the differences in morphology exhibited by the lizards as occurring due to adaptation to the varied environmental conditions or because of the nutrients available in the four Canary Islands. In a bid to ascertain whether this relationship between the morphological characteristics of lizards and the environmental conditions in the different islands existed, 296 lizards were identified as an effective sample for the study. Notably, the 296 lizards used in the study were obtained from the four islands which exhibit varied environmental conditions. The lizards were transferred to a laboratory and effective preservation occurred in preparation for the statistical analysis. Notably, there was a possibility that lizards from the same island would have different morphological characteristics. Among the 296 lizards, 88 were from the La Gomera islands while 74 were from the Gran canary. In addition, 85 lizards were collected from the Tenerife Island and the remaining 47 were obtained from El Hiero Island. The study observed body scalation and body dimensions and went forth to use the one way ANOVA to analyse the covariance between the morphological traits and the environmental co nditions in each island. There was evidence that there is an existing correlation between the two variables in the different Canary Islands. Evidently, obtaining a sufficient sample size of the four Canary Islands, considering the geographical condition of each was a major challenge. This required both time and adequate resources as well an effective identification and collection technique of the Chalcides lizards. Moreover, the climatic conditions of the islands were not favourable for the researcher and the research required resilience if an effective sample size was to

Impact Of Volcanic Activity On The Environment

Impact Of Volcanic Activity On The Environment The research examines the impact of volcanic eruption on the environment and on society. The work aims at exploring four different types of volcanic eruption, the negative and positive impact of volcanic eruption and the health and safety measures during and after volcanic eruption. A total of thirty questionnaires were sent out to friends, staff and students of Cambridge education group, twenty responded with useful information which has influenced the content of this research. The questions includes, have you ever experienced volcanic eruption in your country, the positive and negative impact of volcanic eruption. The comment they made within the defined range was critically analysed by the author by making reference to secondary sources .It was found that the eruption in Iceland was a composite volcanic eruption which lead to closure of several airports around the world. Volcanic eruption has a devastating effect on our society and could lead to loss of lives, income and properties. iv INTRODUCTION The name volcano has its origin from the word Vulcan, a god of fire in Roman mythology. Most people instantly think that a cone shaped mountain with smooth steep slopes, perhaps with a snow covered peak and a ring of smoke rising skyward. The description is accurate but applies to only one type of volcano which is the stratovolcano. Although there are other types that differ in many ways from stratovolcano, some volcanoes are composed of long, gentle slopes often covered with fertile soil while some have no vertical structure instead composed of a depression hundreds of yards deep and extending over several miles. The shape of volcanic structure is clear indication of the type of activity carried on by the volcano .A volcanoes type of activity is also related to the chemical and physical properties of magma produced. Mauro R(2003) 1.1PRODUCT OF VOLCANISM Volcanism in Iceland results from divergent plate movement across the Mid-Atlantic Ridge and excessive production of magma in the North Atlantic Mantle plumeà ¢Ã¢â€š ¬Ã‚  Freysteinn (2006) The product of volcanic eruption are lava, gases and fragmented material such as ash which is derived from molten rock called magma .Magma is a molten matter of silicate composition. Silicon is the main constituent of most minerals and rock in the Earthà ¢Ã¢â€š ¬Ã¢â€ž ¢s crust and also contains dissolved gases which is less dense than solid rock and tends to work it way upwards through fissures .lava is a magma that has erupted at the surface.The term lava applies both to the molten material and to the rock that forms after magma has cooled and hardened. Schminike ( 2004) 1.2 BACKGROUND OF STUDY In the 9th century AD, the Vikings settled in Iceland and established a council that documented its first historical volcanic eruption .The heroic tale was written in the 12th and 13th centuries after a third of the population died from smallpox and in 1783-1784, Laki eruption killed a-fifth of the remaining population by famine. Iceland gained sovereignty from Denmark in 1981 and completed independence in 1944 Recently,the Eyajallajokull volcano which is known as the iseland-mountain underglacier, situated in the southern Iceland erupted spectacularly on the 14th of April 2010 ,after having been dormant for almost 5000years .During this eruption ,the subglacial eruption produced a large ash plumes that drifted over Europe and forced an unprecedented closure of airspace in Europe and other countries .The Iceland owe its existence to a large volcanic hot spot sitting on a mid-ocean ridge .The plate boundary between the American and Eurasian tectonic plate crosses Iceland from the south to the north and spreading process can be directly measured and observed on land .Chimu (2010) 1.3AIMS AND OBJECTIVES Volcanic eruption in Europe can cause severe damage in localized areas. This can be seen in Iceland, a country prone to volcanic eruption. Volcanic eruption has the ability to irreparably damage plant and animal ecosystems and also human social environments. This report seeks to explore the types of volcano, the positive and negative impact of volcanic eruption. This report will also show the health and safety measures during and after volcanic eruption. 2 2.0 LITERATURE REVIEW The Authors below has discussed the phenomenon on the previous volcanic eruption on different locations. This has been incorporated by the author in view of the recent volcanic eruption in Iceland. According to Grattan et al (1991) historical document from A.D ,1783 demonstrated that volcanic gases emitted in an eruption in Iceland did have a severe effect on both the physical and human environment within Europe. The Laki volcanic eruption in southern Iceland in 1783, resulted to high release of haze which were felt all over Iceland .The damaging effect led to destruction crops and vegetation, cultivated crops and vegetation were burnt and withered by acid precipitation. Caseldine (2009) Mount Pinatubo is a volcano that stands 5770 feet, which is located in Philippine along the coordinates 15oN,1200E. The eruption in Mount Pinatubo on the 15th of July was the second largest most violent volcanic activity in the twentieth century after being dominant for over 500 years .The action led to the release of nearly 20 million tons of pyroclastic debris which actually resulted to the destruction of more than 200,000 acre of land and also gave rise to major casualties and damage.This includes the death of more than 700 people and destruction of more than 200,000 homes. Yacove ( 2003). In the morning of May 18th ,1980 Mount St Helens erupted a pyroclastic material which constituted a hot pumice and ash. Approximately 400 meter of the mountainside blew outward that morning. About 60 square kilometres of the neighboring valley was filled with debris.The explosive eruption of Mount St Helens caused the death of over 50 people .Allan (2003 ) Kilauea is lacated between the southeast and it is the spot where all active volcanoes in the entire Hawaiian chain occurred,perhaps the world`s most active volcano . Kilauea`s frequent eruption makes the crater a great study site for volcanologists. In Hawaiian tradition Kilauea is also the home of Pele,the Hawaiian volcano goddess. During the nineteenth century the eruption occurred more often and have contributed to the Kilauea`s reputition, both as a geologic site of wonder and as spiritual site of significance to some residents of Hawaii Allan( 2003) The stramboli volcano in Italy is archytype for strambolian activity (carniel and lacop 1996) another feature of this volcano is the presence of continous volcanic tremor (Ripepe and Gorder1991) .About twice a year the volcanic eruption that occurred showed paroxysmal activity that effected tourist visiting the volcano( Jaquet and caniel 2001) 3 3.0 METHODOLOGY This research has been conducted by the author through the use of primary and secondary sources .Primary data were achieved by survey, interviewing people both verbally and online on the account to the recent volcanic eruption that occurred in Iceland and previous eruption in other countries. A total of thirty questionnaires were issued out to students, tutors, administrators and an expert on the field of structural geology. The information received were critically analysed and incorporated into the report. Secondary sources were evaluated from two different research trends which are quantitative and qualitative analysis. These analysis were established by making reference to books from the library, journals, articles and also e-books such as goggle scholar ,goggle books were utilised .Data collected from these material were re-examined by comparing, evaluating both information from primary and secondary data 4 4.0 VOLCANISM The frequency, magnitude and kind of volcanic eruption are likely to change in the future. The earth has been formed about 4.6billion years ago with consistent occurrence of volcanic eruption. Each year about one-tenth of the active volcanoes on earth erupt. One in every six of the active volcanoes on earth has led to loss of lives and properties as a result of this activity , cities and region has been devastated. Disastrous volcanic eruptions are characterised by rapid onset of their climatic phase and by a wide variety of eruptive behaviour and effects. High and low temperature particularly mass flows of different types, such as debris, avalenche, pyroclastic flows and debris flows but also including atmospheric transport of ash for hundreds of killometres ,during a dynamic eruptions, huge masses of gasses are released into the stratosphere ,forming aerosol that globally effect the climate and the ozone layer for years.Volcano are certain to increase in future the reason are manifold. Schimike(2004) 4.1. CAUSES OF VOLCANIC ERUPTION A volcano is composed of three basic elements. A vent through which volcanic material erupt. A conduit which is the passage that allows magama to reach the surface of the earth and a reservoir or magma chamber deep in the earth crust. All volcanic eruption are not alike, some eruption are quiet with lava slowly oozing from a vent .Other eruption are very violent with lava and other materials being injected hundred miles into the air. Gases from within the earth interior mix with huge quantities of dust and ash and rise into the air as a great dark clouds that can be seen from many kilometres away. Some dark coloured lava is thin and runny and tends to flow as well. Explosive eruption are caused when lava in the vents hardens into rock.Steam and lava build up under the rocks when the pressure of the steam and new lava becomes great, a violent explosion occurs as a result of internal pressure within the rock.Gases and rock shoot up through the opening and spill over or fill the air with lava fragments.A volcanic eruption have been known to knock an entire forest ,furthermore an erupting volcano can trigger tsunamis,flashfloods,earthquakes,mudflow and rockfalls. After Floyd (2000) 4.2 TYPES AND COMPOSITION OF VOLCANOES There are different kinds of volcanoes which are classified based on the shape of the volcano ,the materials they are built of and the way the volcano erupt .The author will explain four different types of volcano which are grouped as: 1. Strato volcanoes 2. Cinder cones volcanoes 5 3. Shield volcanoes (which are also called shields) 4. Lava dome volcanoes 3.2.1 strato volcanoes The stratovolcanoes are also known as a composite volcanoes. Magma moves to the surface from its source miles below the crust and often changes in composition. There are different types of magma which are associated with different types of volcanoes. Basaltic magma, which comes from deep within the mantle undergoes little chemical changes during the process of volcanism. During this process some amount of fluid allows the magma to let-off its gas safely. The resulting landforms are cinder cones and shield volcanoes. In stratovolcano,magma`s chemical composition may change to a more viscous type.The chemical composition will eventually be responsible for the creation of volcanic rocks which are different from basalt.The three most common rock types found in strato volcanoes ,with variations in their composition are rhyolite,decite and andesite.Andesite has similar composition to basalt but has more percentage of silica content than basalt ,however Rhyolite on the other hand ,is more i dentical in composition to its parent rock while Decite is the middle in terms of composition. The rock types serve a purpose in composite eruption because it tells geologists the source of magma and the phase of eruption. The composite volcano are composed of virtually all the material a volcano can eject from a vent and the materials discharged piles up to form steeply sloping cone of the volcano. Prisciantelli (2004) 4.2.2 CINDER CONE VOLCANOES Cinder cones are one type of volcano or volcanic landform. They are associated with subsurface contact which amounts to their volatility.Magma on the top of a chamber is loaded with gas during the process of volcanic activity.The pressure from the gases subsequently necessitate to the explosiveness of the eruption while at the bottom of the chamber the pressure is less and magma tends to flow through a break in the cone. Furthermore when gases are thrown in the air during eruption the lava shatters and hardens to small cinders and ash which piles up around the vent. In addition the cinder cones are usually steep-sided and the top of the cone has a bowl shape which are small in size. The typical behaviour of a cinder cone is an eruption from a vent in the earth, concurrently, cinders are being accumulated to form the cone ,followed by a possible break at the base of the cone from which lava flows. The cinder is used for construction and also seperated by snowplows during winter to improve driving on icy roads.Prisiantelli(2004) 6 4.2.3 SHIELD VOLCANOES The shield volcanoes are another type of volcanic structure but are much broader than cinder cones, generally covering large areas. Lava constantly flows through the vent and they do not produce cinders, ash like the cinder cone volcanoes. The shield volcanoes are not as explosive and destructive as composite and cinder cone volcanoes .However they are harmful to anyone they come in contact with and also their lava flow covers a wider range of distance .The lava has multiple flows while one is hardening the other tends to begin and run over the top of the initial flow. In this manner, the volcano builds outward into a broad slope, its structure is high and wide and often covers many mile during this activity. The slope is more gradual than that of the composite or cinder cone volcano. Shield volcanoes has a similarity with that of the cinder cones in terms of basalt lava composition. The rock type of the shield volcano is andesite and the fluid flow is different from the basaltic flo w. Pisiantelle(2004) 4.2.4 LAVA DOMES VOLCANOES Lava domes volcanoes are less common and are also known as volcanic domes and plug domes which are steep-sided, bulb-shaped mountain that forms when viscous felsic magma and occasionally intermediate magma, is forced toward the surface. When pressure below the chamber is great , the felsic magma tends to move gradually. This is as a result of the sticky magma that are contained in a chamber. Some cited examples of a lava domes volcanoes was an occurrence in Washington which began in the year 1980 on Mount St. Helens. A number of lava domes were buried in the crater of Mount St. Helens and most of these were destroyed during subsequent eruptions. Since 1983, Mount St. Helens has been characterised by occasional growth and renewed eruption in 2004.More so in June 1991, a lava dome in japan, the unzen volcanoe collapsed under its own weight which caused debris to flow and also hot ash that killed 43 people during the eruption. The lava domes eruptions are among the most violent and destructive. In 1992 on Mount Pele on the island of Martinique, viscous magma accumulated at the highest point of the Pele and eventually pressure increased until the side of the mountain blew out with a huge explosion which led to the high discharge of dense cloud of pyroclastic materials and a glowing cloud of dust called the Nuee ardante (glowing cloud in French).The explosion also led to swirling cloud of white-hot ash and gases with an internal temperature of 700 degree celsius that consumed everything in its path. Subsequently, Nuee ardent passed through 7 St.Pierre within two or three minutes ,followed by a firestone as an ignitable material which burned and exploded. Approximately 28,000 resident of the city died during this action. According to Wicander (2008) 8 5.0 THE IMPACT OF VOLCANIC ERUPTION ( CASE STUDY:ICELAND VOLCANO 2010) Iceland has a high concentration of active volcanoes due to unique geological conditions. There are about 130 mountains of volcanic origin,18 of which have erupted since the colonization. A high amount of volcanism is concentrated along the plate boundary ,which runs across the island from the southwest to the north west. In the south and southwest regions of the island we find the Hekla, Eldgja and the Laki craters, also the Arafajokull and Snafellsjokull. Eyjafjallojokull is situated to the north of skoger and to the west of Myradalsjokull .Hooper (2010) Geologist explain the high concentration of volcanic activity in Iceland by a combination of the island position on the mid-atlantic ridge and volcanic hot spot underneath the Eurasian and North American plates. More so Icelandic eruptions are famous for their massive volume of erupted ashes and for vast lava outflows. The most common type of volcanoes are the composite volcanoes which spread over vast areas of the country and usually arranged in chains. Over the last 500years Iceland`s volcanoes have ejected about one third of the total global lava output ,although the Laki volcano in southern Iceland which erupted in 1783 and was classified as the largest erupted lava since the Iceland`s colonization .The most recent volcanic eruption in Iceland began on the 14th of April at the Eyjafjallokull mountain .Geologist explained during the eruption ,that the activity of the volcano increased incessantly, spewing a plume of ash which was approximately 5.3 miles high into the atmosphere. Thousands of flights were cancelled with millions of travel plans affected. During the incidence it was estimated that shutting down the United kingdom`s airspace alone for a week incurred lost of over 100 million pounds. More so business plans and those involved in importation and exportation of goods were disrupted. Th e global cost of the disruption, resulted in a loss of billions of pounds.Hooper (2010) 5.2 PRIMARY ANALYSES Questionnaire survey detailed in the report will help to influence some of the content of this report, other influences will be interviews both verbally and online. Although it was difficult to draw conclusions from some of the responses particularly the open-ended response. This investigation was carried out on friends lectures and also on students and staff of the Cambridge education group ,between 4th July to 11th July 2010 A total of 30 people were advised to fill in a questionnaire and out of the 30 people ,the number of responses from both online and paper questionnaire at the time of this research totalled 20 and out of the people that responded 18% were males while 12%,were females. The age-group of these participants ,27% were under 40 whereas 3% were above 40. Question 8,on the questionnaire was, have you ever experienced volcanic eruption in your country. A total of 27% partakers said No, while 3% said yes. Furthermore , question 10 was ,do u think that volcanic activity has a negative impact on the economy of a country. 30% of the respondents said yes and there reasons were, it can affect business activities by giving rise to delay on production services and that volcanic eruption may defer tourist and cause a lot of damages to properties ,vegetation and livelihood. Smoke haze will cause or necessitate delays both on residents and visitors going for tourism and other important activities . Most airports might likely to be shut-down during this activity. More so most manufacturing industries that rely on importation and exportation will put a halt on their activities there by affecting income generation and revenue for the government and private sector as a whole. Question 12 , was about the positive impact of volcanic eruption.27% of the respondents said that volcanic eruption, only has negative impact whereas 3% out of the respondents who said Yes, provided information within the defined range. The comments they made were that ,many years after volcanic eruption it could aid tourism and also produce interesting geographical and historical features. Furthermore,ash which is a product of volcanism enriches the soil when it is being deposited at the surface of the earth. In addition new rocks are formed from magma and can be used for infrastructural development. The analysis is shown on table 2 5.3 FINDINGS The preceding chapters focused on the origin ,composition and types of volcanoes. More so, on the procedures and analyses of primary data to meet the requirement of the author. This chapter will analyse further on the negative and positive impact of volcanic eruption on society in relation to primary analyses. This has been achieved through secondary sources. Depending on the type of eruption and its location, volcanic eruptions has overwhelming effects through a number of displays. The negative impact includes, the high release of haze during eruption ,which leads to destruction of crops and vegetation from acid precipitation.Caseldine( 2009). Pyroclastic resulting from eruption and can cause ample damage depending on the size of the layer deposited. A Thickness which is less than 1mm will act as irritant to lungs and eyes and also lead to closure of airport due to the potential to aircraft and contaminate water within the area. While a layer of ash with thickness between 1-5mm will cause minor damage to buildings and blocking air filters. This can also lead to electricity cuts due to conductivity of wet ash. A layer of ash which is about 5 -10mm will destroy crops and pastures, causing light weight buildings to collapse and also effect rail transport through signal failure. After Gottsamann (2008) Furthermore,a cited example of the negative impact was the eruption in Laki which is located in southern Iceland in the year 1983 .When lava poured out from a total of 135 newly opened cratars, it was estimated that during this eruption some half billion tons of 11 toxic gases was expelled into the atmosphere and killed over 16,000 people and slughter about 60% of cattle in island. After Gottsamann (2008). Volcanic eruption deposit materials (ash) on the surface of the earth and after a long period of time due to physical and chemical changes ,the ash provides nutrient to the surrounding soil. Volcanic soils are potentially fertile as the ash can contain trace element beneficial to the growth of plant .This can relatively encourage high population and intense agriculture within the area. Volcanoes are often located in region where there is high agricultural production. Volcanoes, provides strikingly natural beauty which can attract tourist .An example demonstrated is the volcanic eruption which occurred between 1963-1965 in costa rica ,called the Irezu volcano. The eruption was reported to be responsible for 4.3% increase in the number of tourists between 1963-1964 . Indirect economic benefit can also be initiated in response to the indications or threat of imminent volcanic eruption. Further example, was the volcanic activity that took place at Rabaul papua , New Guinea between 1983 a nd 1985 which led to a number of improvement to infrastructure on that location.This includes advancement of air-strips, road and bridges ,water and power supplies ,health facilities and communications .However during this growth ,food production increased as a number of people cultivated food gardens outside the danger zone.After Gottsamann ( 2008) 12 6.0 HEALTH AND SAFTY MEASURES DURING AND AFTER VOLCANIC ERUPTION WHAT TO DO DURING VOCANIC ERUPTION 1. During volcanic eruption,it requires immediate evacuation to a safer location ,rock debris ,lava flows and ash will make the area around the volcano dangerous to anyone that stays 2. If instructed to evacuate follow the directions of the authorities. 3. Evacuate to an area upwind and higher ground .Flash floods, mud and poisonous gases will accumulate in low lying areas 4. If you are unable to evacuate ,seek shelter indoors and make sure all windows and doors are locked to keep ash out . 5. Store all vehicles and equipment inside a garage and leave them, until the eruption has ended. 6. If you must go outdoors use goggle to protect your eyes and use a face mask or hold a damp cloth over your face to aid breathing. 7. Avoid falling volcanic ash ,cover your mouth and nose and wear long-sleeves to avoid irritation or burns on the skin. 8. If you are in a vehicle keep the engine switched off. Avoid driving when ash is falling heavily as driving will stir up more ash that may clog your vehicle`s engine. Bickley (2010) WHAT TO DO AFTER VOLCANIC ERUPTION 1. Minimise your movement and keep all windows and doors closed. 2. Always ensure the safety of yourself and your family before responding to the needs of others. Do a headcount to make sure the members of the family are safe and sound. 3. Check for injuries,do not attempt to move seriously injured person unless they are in immediate danger of death or further injury. 4. Drive slowly and carefully with your lights on. 5. Remove ash from your roof,more than ten centimetres of ash may be enough for your roof to collapse. 13 6. Hose down outside with a little water to dampen the ash .This helps to keep it from blowing around. Bickley (2010) 14 7.0 CONCLUSION In the assessement of the impact of volcanic eruption on the society and environment ,it was found that volcanic eruption are not alike ,some are quiet while some are violent ,This action depends on the internal pressure exerted on lava. The pressure necessitates gases and rocks to shot up through a vent and conduit and fill the air with lava fragments. It can be seen that the recent volcanic eruption in Iceland on eyjafjallolojokull province was a composite volcanic eruption which has ejected about one third of the total global lava output over the past 500years .The recent volcanic activity in Iceland occurred within a month and resulted to a loss of billions of pounds around Europe. The sudden violence of volcanic eruption causes catastrophe and devastation on the environment .This includes destruction of buildings, crops and vegetation. Could also lead to flight and vital activity delayed The findings also indicate that volcanic eruption has more negative impact on our society and these could affect income generation and revenue for the government and private sector.

intelligence Essays -- essays research papers

Intelligence is the level of competence, ability to learn or to some people it is how well an individual performs on an IQ test. The structure of intelligence is best subdivided into two significant categories. They are environmental and hereditary influences. Environmental differences can be divided into different factors. The deprivation model of social class and intelligence consists of three variables. These variables explain, in terms of environmental factors, development and performance which are correlated with social status. The first of these variables consists of the combination of birth order, nutrition, and prenatal care. Children who are first born, on average score better on mental tests. There is a definite higher number of first born children among higher socioeconomic groups as opposed to lower socioeconomic groups. According to Bruce Eckland, children of higher economic class tend to be brighter, on average, than children of lower economic groups (65). Both prenatal stress and malnutrition, impair development and are found much more frequently among lower socioeconomic classes. According to Philip E. Vernon, the fetus can have lack blood supply and growth of the fetus can be disturbed if the mother takes certain drugs or suffers from certain diseases. Severe stress on the mother can also be hazardous to the fetus (84). These conditions expressed are both genetic and or resulting from environmental conditions and are known to as constitutional factors. The second variable of the deprivation model which helps exhibit differences in performance is the cultural variable. It seems that lower socioeconomic classes experience a unique pattern of behavioral and psychological traits which impair development in children raised in these conditions. The last environmental variable that accounts for differences in the cognitive development is the social cultural variable. This variable includes deprivation which involves socially structured inequalities in education and other social opportunities for improving performance. Sidney W. Bijou states that in order to help development, an ample supply of physical stimuli for cognitive development is favorable along with the people who have to manage these stimuli in contingent relationships after the birth of the child (230). Another environmental contribution to intelligence, which Bijou points out is th... ...ort the conclusion that both genetic and environmental components have a significant effect upon the intelligence of the child. There has also been some research done on identical twins who live in different environments. They have been compared with siblings who are not twins but live in the same environment. The correlation results for twins who live apart is .75 and .24 for no-twin siblings who do live together. It seems that together, these two correlations almost add up to 1.00 which is the total phenotypic variance. Vernon points out that the effect of genes is much more powerful than that of the environment. Even though the precise values of the correlations are of dispute, analyses of kinship data, concludes Vernon, provides the most convincing demonstration of genetic influence on intelligence. Undoubtedly ,the subject of intelligence can be defined in many ways. To better understand intelligence psychologist have rendered two main influences as cause for variable intelligence levels. These two main influences as discussed previously cannot be explained as one being the main determinant of intelligence. This two influences are environmental and hereditary influences.

Households and domesticity in ancient world

How Valid is Mazarakis Ainian ‘s Hypothesis that Rulers ‘ Dwellings in the Early Iron Age were the Forerunner of the Urban Temples of Later Periods?In this paper I am traveling to review Mazarakis Ainian ‘s averment that there is a strong nexus between swayers ‘ homes and early temples in both map and architecture. I shall get down by placing what it is that separates a swayer ‘s home from the remainder of a community and shall so seek to place why a house would be used as a temple and the grounds for why there would hold been the passage to a dedicated spiritual edifice.House types of the Early Iron AgeThe period of the Early Iron Age ( EIA ) covers about 1100-700 BC and encompasses the so called ‘Dark Ages ‘ which followed the Mycenaean prostration and which ends in the passage to the Early Archaic period of the seventh century. It can be divided into the Protogeometric and Geometric periods of 1100-900 and 900-700BC severally. It is Mazarakis Ainian ‘s chief statement that due to the evident absence of temples of any sort within colonies prior to the mid eighth century BC, swayers ‘ homes alternatively served as Centres of communal cult ( 1988: 106 ) . It would hence be utile to look at the scope of house signifiers known from this early period, to place what separates elect lodging from other constructing types and besides the grounds they contain to propose ritual or spiritual activity. Although there are comparatively few colony sites staying, peculiarly 1s incorporating identifiable house remains or foundations, in comparing to subsequently periods in the Grecian World, Lang recognizes two chief types of house agreement ; detached and agglomerated. Both types of colony normally show that they were unplanned, having irregular street layouts which most frequently follow the local topography ( Lang 2007: 183 ) . The colony of Zagora on the island of Andros is demonstrative of the agglomerative house type while Emporio on Chios shows detached. This may nevertheless be brooding of colony size ; Zagora may good hold begun with a degage house agreement but its location on a drop top tableland and ensuing bounds on infinite, any addition in population may hold required new houses to be built in close propinquity to bing 1s. The alteration from little to big bunchs of houses can be seen in the programs drawn of the EIA and Archaic remains at the site ( fig. 1 ) . This has nevertheless led to several bookmans proposing that the house layout of Zagora reflects an early illustration of the courtyard house prevalent in the Classical Period ( Coucouzeli 2007: 169-181, Morris 1998 ) . The statement for this does non look wholly convincing, but I shall non turn to it farther in this paper. House types within these agreements besides varied. They were most normally composed of one or two little suites with rectangular, egg-shaped, apsidal or the somewhat less common round land programs ( Mazarakis Ainian 1997: Ch. 1 ) . The agglomerative colony lent itself best to rectangular land programs as seen with Zagora ( figure 1 ) . Geographic location appears to hold played a portion in the distribution of the different house types with, for illustration, egg-shaped edifices of the Geometric Period being chiefly found in Attica and Euboea, the East Greek islands and West seashore Asia Minor but seldom identified elsewhere ( Mazarakis Ainian 1997: 86 ) . It is the edifices of apsidal and rectangular programs that Mazarakis Ainian suggests were the ancestors of the Archaic temple and the most preferable designs for swayer ‘s homes. They can be divided into two groups ; those with a closed frontage are classified as ‘oikoi ‘ and those with an unfastened frontage are known as anta edifices ( 1997: 259 ) . At many of the colonies there is normally a home that stands out in footings of size, program and location from all others in the locality and it is these that are assumed swayers ‘ homes. Figure 2 high spots this in a comparing of elect homes of certain type, dwelling of a chief room with smaller rear chamber, and other domestic edifices of similar form.The House as TempleThe extent to which these likely elite houses show similarity in signifier and map to the first urban temples will now hold to be considered. To get down to reply this, the grounds for why these houses would be used as focal point of ritual ac tivity in the first topographic point demand to be looked into. M. Ainian calls these edifices swayers ‘ homes, but who were these powerful work forces and how far would their power have extended within their community? Mazarakis Ainian suggests that the swayers who inhabited these homes would hold been work forces who came to power on either a familial footing or through possessing desirable personal virtuousnesss ( 1997: 270 ) . In anthropological footings this would do them either heads or large work forces. He proposes that in some countries these powerful work forces may hold had their beginnings as local governors in the Late Helladic IIIB Period, and so would hold maintained control of little colonies after the Mycenaean prostration. In most countries colonies would hold been little made up of one or two drawn-out households, with the caput of the dominant or possibly oldest family going responsible for the direction of communal personal businesss ( Mazarakis Ainian 1997: 375, 393 ) . Thomas and Conant express it good: The community is virtually an drawn-out household, and the small town leader, the caput of the most of import household. ( Thomas and Conant 1999: 52 ) This reflects what is thought from Homer ; that the Oikos consisting of drawn-out household of possibly three coevalss was the basic ‘kinship, residential and economic unit ‘ with any figure of oikoi doing up a community ( Donlan 1985: 299 ) . It would merely look logical that as portion of his control of communal responsibilities the ‘chief ‘ would besides be in charge of spiritual cult pattern. When the colony was little and lone consisting of the one affinity group the ideal topographic point to idolize a divinity or ascendant would hold been within his place. As the colony grew possibly this pattern continued as tradition. It is M. Ainian ‘s position that by literally lodging spiritual pattern the swayer was keeping his prestigiousness and control within the community ( 1997: 393 ) . The control of faith by a individual swayer, or double swayers in this peculiar instance, was continued into subsequently periods by the male monarchs of Sparta who cont inued to move as main priests, retaining their spiritual function ( Mazarakis Ainian 1988: 118 ) . This would look to propose that spiritual responsibilities would and could hold been controlled by the colony leader. There would therefore look to be several strong accounts as to why a swayer ‘s house would hold come to be used as a precursor to the temple. The archeological grounds is largely in support of this position, with domestic and ritual artifacts frequently found in association. Nichoria, a site in Messenia is a good illustration of this. At this site two peculiar house remains, known as unit IV-1 and unit IV-5, stand out from the remainder of the homes in the locality. As a consequence it could be said with comparative certainty that they held some particular importance within the community. Both were rather big apsidal edifices surrounded by little seemingly low position apsidal huts. The first, IV-1, has been dated to the tenth century BC while IV-5 most probably replaced it in the 9th. IV-1 is the most complete of the constructions and digging found that it contained a paved circle raised on a dais and covered with a bed of burned stuff ; nearby an sum of animate being bone was besides recovered. This suggested to the excavators that it may hold been a temple, with the paved circle operation as an communion table. Other di scoveries of a domestic nature were besides found nevertheless, proposing that it was possibly of importance both as a home and for its ritual significance ( Lukermann and Moody 1978: 94 ) . Ritual banqueting was another facet of ancient Greek spiritual pattern that M. Ainian identifies as perchance holding a case in point within the swayers ‘ home. Whitley though argues that the big sums of animate being castanetss and imbibing vass in association with fireplaces and benches in some homes does propose banqueting, but for the intent of doing bonds of commitment and beef uping authorization within the community ( Whitley 1991: 185 ) . Mazarakis Ainian does non deny that banquets were most likely taking topographic point for these grounds, but besides tenuously suggests that they would hold been held for ritual intents ( 1997: 379-80 ) . The grounds he cites for this nevertheless is limited at best, and he does rely somewhat on justification from the Homeric heroic poems in this peculiar country, despite his unfavorable judgment for other bookmans on this point. I am nevertheless inclined to take up his point of position in this affair. Although it is certain that fe asts did happen in swayers ‘ homes, the grounds available makes their purpose hard to find, but as antecedently argued, the swayer took on the function of ‘priest ‘ which makes it likely that some signifier of ritual dining must hold taken topographic point within his house alongside the other signifiers mentioned. The architectural similarities between swayers ‘ homes and early temples besides give acceptance to M. Ainian ‘s hypothesis. They portion similar land programs, being largely rectangular or apsidal and holding the entryway in the short side, significance that every cult edifice of the Late Geometric Period had an architectural opposite number in a domestic edifice of the same or earlier day of the month ( Mazarakis Ainian 1997: 388 ) . Apparently so this demonstrates really close ties between the edifice types that must certainly stand for a continuance of tradition. Snodgrass nevertheless does foreground that shrines may hold existed as separate entities in earlier periods as direct ancestors of the classical temple, but because architectural criterions were lower they can non be differentiated from domestic constructions ( Snodgrass 1980: 58 ) . Some edifices, such as edifice C at Koukounaries, appear to portion greater similarity with banqueting halls than with abodes as they consist of merely the one big room without any noticeable divisions ( figure 3 ) . A individual unfastened infinite like this would look more ideal as a topographic point for banqueting than as a life infinite for the elite. This would propose a remarkable function and specific intent for these peculiar edifices instead than holding the double intent of brooding and Centre of cult that is cardinal to M. Ainian ‘s statement. If this was the instance so the temple, which fulfilled the function of communal banqueting hall and garnering topographic point in the Archaic Period, could be seen as holding its beginnings as a typical, separate construction in an urban scene at a much earlier day of the month. Lang though believes that EIA society would non hold been developed plenty socially or economically to let for the building of public edifices of remarkable map ( Lang 2007: 186 ) . Ideas of public and private infinite had non been developed and so the separation of domestic and sacred would non hold been necessary ; the demand for a typical temple edifice within the confines of the colony would non hold existed. Small discoveries from within many of the big constructions suggest a scope of domestic maps took topographic point within, instead than the remarkable grounds of dining that would be expected from a banqueting hall. The bulk of edifices believed to be swayers ‘ homes are divided into compartments or suites with edifice C at Koukounaries being one of merely several exclusions to this ( Mazarakis Ainian 1997: 271 ) . His most convincing statement is that without these being classed as places of governing households, there would be small archeological grounds to propose Grecian society was stratified as opposed to classless during the EIA ( 1997: 271 ) . It would therefore look improbable in visible radiation of the grounds that temples would hold existed in their ain right during in urban contexts during this period. Rulers ‘ homes apparently would hold filled the function finally played by the temple, with the leader, the head or large adult male, executing the responsibilities of priest.Passage to TempleIt does look that swayers ‘ homes would hold been the Centre of at least some sort of ritual spiritual activity within EIA communities. So why was there the passage to the separate urban temple at the terminal of the 8th and beginning of the seventh century? These new temples, in the beginning at least, would hold carried out the same spiritual map as the houses of the elite had done, but were merely designed for this remarkable intent. This alteration must certainly hold represented new thoughts emerging of dividing public and privat e infinite and in bend reflect societal, political and even economic alteration. Prior to the mid eighth century, temples as edifices in their ain right merely appear to hold existed at extra-urban sanctuaries ; that is those which are outside any peculiar colony. One illustration of such a edifice is the rural shrine at Pachlitsani Agriada near Kavousi on Crete ( Mazarakis Ainian 1988: 116 ) . The edifice contained a bench on which idols stood and besides the remains of several graven images, perchance dedications to the goddess Eileithyia ( Mazarakis Ainian 1997: 212 ) . It is dated tenuously from the manner of the graven images to the Protogeometric at the earliest and the bend of the 8th/7th century at the latest, with M. Ainian preferring the earlier day of the month. There was hence a case in point for edifices that were built for the exclusive intent of worship, either to a God, an ascendant or hero, but non within a colony. As has been mentioned the map of a temple was carried out by the swayers ‘ home and so there was no demand for such a edifice u ntil about 750BC.From so onwards this position changed and temples began to look in a figure of urban colonies across Greece. Of class the alterations taking topographic point did non make so at the same time across the full Grecian Universe, but 750BC appears to hold been the turning point from which the temple finally dominated as the primary focal point of spiritual cult. Mazarakis Ainian suggests that the passage to temples occurred as a consequence of political and societal alteration ; specifically the diminution of the monarchal system. He proposes that when the so called ‘basileus ‘ , the leader of the community, had control over the direction of communal personal businesss including spiritual facets, the sacred and non sacred were non separated. It is his sentiment therefore that the rise of temples from the mid eighth century was a direct consequence of the abolishment of monarchy in favor of an blue system. The former leader would hold lost many of his powers and in peculiar the control of cult activity ( Mazarakis Ainian 1988: 118 ) . This implies that control would hold passed to the ‘state ‘ as it existed at the clip, followed by the separation of the every-day into public and private, sacred and non sacred. This is one possible account as to the passage of cult from swayers ‘ brooding to temple and it is closely linked with the other chief account ; the rise of the polis, which shall be discussed shortly. Harmonizing to M. Ainian, the building of temples meant the remotion of cult from private to public control and so besides implied the remotion of power from the single i.e. the colony leader. Although it is widely held that power did bit by bit go more widely distributed between a figure of elect as opposed to being held by one adult male, and is seen in the archeological record by the progressively hard undertaking of placing swayers ‘ homes from the architectural remains of this period, it could non hold been the instance everyplace as evidenced by the continued presence of sovereign into the Archaic Period and beyond ( Mazarakis Ainian 1997: 382 ) . His logical thinking does non take into history that temples themselves, as monumental constructions, could besides be interpreted as shows of authorization and wealth of a high position person in the same manner swayers ‘ homes had done, while possibly at the same time in other countries stand foring competition between c ommunities and a show of the corporate power of the ‘state ‘ . The best counter-argument to his position must certainly be the instance of Sparta, as a good documented metropolis where the establishment of kingship was maintained, yet besides featured temples. He argues that for monumental temples to be constructed it required communal consensus, attempt and resources that would non hold been possible under a individual swayer ( 1997: 384 ) . Yet, by his ain statement, the earliest temples frequently resembled swayers ‘ homes in form every bit good as map, and so the really first temples at least could hold been constructed utilizing bing resources and work force ( 1988: 116 ) . He is nevertheless right in proposing that a swayer at the degree of ‘chief ‘ would be improbable to command adequate power in order to build a truly monumental edifice of any sort. The ‘Heroon ‘ at Lefkandi may be the exclusion to this ; at 47 meters long, 10 meters broad and dating to c.950BC it was bigger than anything else built in Greec e for more than the following 200 old ages. It has been suggested that this excessively may hold served as a home before being converted into a funerary construction ( De Waele 1998: 384 ) . It would once more confute M. Ainian ‘s theory as it was most probably constructed to house the people finally buried within it instead than for the broader community, but within the range of this paper shall be treated as an anomalousness. This aside so, it would look to come down to a inquiry non of who was in charge, the person or the many, but the phase of development as a society that they were at. Sparta was able to hold temples even under a dyarchy because it had developed into a polis and accordingly was at a phase of political development that allowed for the separation of the sacred and the non sacred, the populace from the private. It has even been argued that it was a necessary demand for the development of the metropolis province. Starr asserts that the outgrowth of purpose built temples indicates civic integrity merely possible through the societal construction and centralized authorities of the polis ( Starr 1986: 39 ) . Thomas and Conant agree to an extent with this position, proposing that spiritual commonalty would hold contributed towards the turning coherence of colonies and added to the sense of community beyond affinity groups. But they go farther in suggesting that this manifested itself in the bu ilding of grander constructions to honor the Gods and hence played a important portion in the development of the community and individuality of the polis ( Thomas and Conant 1999: 138-9 ) . From these two statements the inquiry is formed as to whether the temple was a consequence of the rise of the polis, or if the polis was merely possible through the creative activity of, or at least the societal, political and economic conditions necessary for the building of, the urban temple. To decently reply this would necessitate an in deepness expression into the rise of the polis which is beyond the bounds of this paper, but no affair what the reply it is clear that the outgrowth of both were inexorably linked. If, as harmonizing to Mazarakis Ainian, it was the displacement from monarchy to shared regulation that led to the demand for temples so it would go forth those metropoliss that did non travel through this political alteration as exclusions to the regulation. To give him the benefit of the uncertainty, what he is most likely seeking to state is that urban temples were a phenomenon of ‘state ‘ regardless of its signifier of authorities every bit long as the power was shared in some manner. I would therefore suggest that his usage of the term ‘monarchy ‘ is misdirecting in this context as he alternatively seems to be mentioning to the alteration from chiefdom degree regulation to that of province degree ; therefore indirectly besides back uping the thought that the beginnings of the polis was the ground for alteration.DecisionsSo is Mazarakis Ainian ‘s hypothesis valid? The grounds for the period he is analyzing is comparatively limited, embracing as it do es the so called Dark Age of Greece, but what is known from the archeological record does non look to confute his decisions. That is non to state nevertheless that it to the full endorses him either. In several illustrations presented the archeology could be interpreted in a figure of ways but would look to back up his statement through other indirect associations. This can peculiarly be seen in the grounds for banqueting within swayers ‘ homes which does be, but its ritual nature is difficult to find. Its reading as such is largely dependent on whether the colony swayer genuinely took on the mantle of priest as argued. Although there are several separate and valid statements in support of his point of view, in my sentiment if merely one facet such as the degree of authorization of a colony leader was thrown into uncertainty, the other statements would go well weaker. Despite this, holding considered the chief points of Mazarakis Ainian ‘s statement and the available grounds I have drawn similar decisions, and would therefore back up his hypothesis that swayers ‘ homes were so a precursor in both signifier and map of the early temple.BibliographyCoucouzeli, A. 2007.

buy custom Embracing Technology in Education essay

buy custom Embracing Technology in Education essay In the little schoolhouse painted red that lies in the depth of America, children craving to acquire education sit in rows. These children wait eagerly for what the wise teacher writing on the blackboard has to offer them for that particular day. A clear indication that the teacher is indeed wise is illustrated by the shiny apples that she offers the children as an appreciation for their respect and gratitude. American education however, displays a very different setting from the one mentioned above. The classrooms, beige in color are filled with texters and passers who never concentrate and often make the teacher to struggle to pass information to the students. In this kind of a set up, the bright students are often bored while those slow to understand are left behind. There is great anxiety concerning standardized testing and results to low scores. According to National surveys, the education quality in America has been doubted by most parents and it has been proven that their doubts have a good basis since the test results confirm this openly. It is however on the contrary that most parents speak well of their childrens teachers and in the process tend to support their own representatives despite the fact that most Americans are in disapproval of the congressional monkeyshines (Ward, 2010). If persons were asked how they experienced their school days, most of them would definitely display mixed feelings on the issue. One thing would stand out is the relationship that existed between them and their teacher. This thus brings out the reason why parents and more so politicians get worried when a kid tends to be more attached to a computer than a teacher. Since we have had the opportunities to try all the other modes of education, it is worth making a try of online education. Through the influence of Arne Duncan the Education Secretary, experienced government officials have made a vow to make a change in the education sector. It is evident that the reforms offered y most of the federal race placed at the top with regards to funds, bring minor changes to the status quo instead of giving encouragement to innovative education. The development of post-secondary education has taken over 10 years and has cost $500 million as a result of the efforts of Duncan since it has thrived without federal assistance. This achievement however has succeeded 15 years late than planned and a bit expensive than it had been budgeted. There has been notable change of lifestyle since the inception of the internet mid 1990s. Amazon and eBay for instance have brought significant improvement in shopping, Google has made information finding very easy, and Facebook has helped keep our friends closure while iTunes has brought a positive impact in our consumption of music. It is rather unfortunate that even with the significant change in technology; kids remain glued in analogue schools (Ward, 2010). Perhaps the existence of teachers unions is the major reason for upholding the traditional classrooms where teachers supervise the children. Although technology has improved a great deal, children are still learning on blackboards and books. It would be proper if they were to learn the same way they acquire information online. The very first step to initiate change is putting reading materials as well as lecture notes online. This situation can allude to the olden days movies where filmmakers shot stage plays and with this regard kids are still watching such kinds of films while the 3-D versions are readily available. It turns out to be very difficult to understand why an English teacher would struggle as the old Shakespeares day to tech a class while YouTube can offer so much on theater arts and film technology such as Elizabeth Theater and Kennedy Center Arts Edge site. Bill Gates listed that online education in the U.SA is among his first priority in his foundations annual letters and with this regard endowed $33 billion. Bill Gates aimed at initiating reforms in eduucation and pointed out that it is very essential to implement interactive forums where students can be assessed for what they know and what they do not know. There is great need of developing mechanisms where teachers can be able to comfortably gauge the number of students who have grasped the concepts taught as well as devising ways of assisting those who have not. Online education has proven its worth due tot the fact that virtual charter schools are already operating in various states. A good example is the Florida Virtual School which offers online classes to its students particularly those enrolled in state system. Teachers are apparently available for any consultations from the students from 8 a.m to 8p.m through phone or e-mail. It is only when it becomes clear that all the students have understood the concept that the state cuts a funding check. This ensures very remarkable performance for the kids who enroll in this institution. In Clayton Christensen book, "Disrupting Class," it is estimated that by the year 2019 most of the high schools in the United States will consume education over the internet. This will however take a lot of efforts if at all is to be achieved since only seventeen percent of the students in high school took an online course last year for school while twelve percent took it for self study. Most of these students are signing up for virtual schools that are in line with the state system although majority of them can be considered to have acquired the information via homeschooling system. It is thus clear that online education is the best remedy for reshaping the education system. Embracing new technology in the education sector would ensure the delivery of quality education and leave no single student without the complete concept of what is taught. Online system can also be set up to ensure more and better supervision than any other learning system. Initiating change in our education system thus proves to the right answer for the improvement of the education system. Buy custom Embracing Technology in Education essay

Labor Economics Article Example | Topics and Well Written Essays - 500 words - 1

Labor Economics - Article Example This should be done even if inflation exceeds the central bank’s target 2%. As Mr. Ball is proposing keeping the short-term interest rate near zero, the Fed is expected to start raising their benchmark short-term interest rate from near zero if the US economy continues to improve. In fact, the Fed’s updated economic forecasts show that unemployment is expected to fall from 5.5% to as low as 4.8% by the end of 2017. Mr. Ball’s thinking is that the Fed can do more by pushing the unemployment rate lower than 5%, albeit temporarily, to create more jobs. Bringing the unemployment rate below 5% could enable some discouraged workers to re-enter the labour market, the unemployed find work, and the involuntary part-time workers find full-time jobs. He proposes that the interest rates be kept near zero well past the end of 2015. The article notes that the Fed officials are worried that the period Mr. Ball is proposing for keeping the interest rates near zero is too long and the inflation could rise too high or fuel detrimental financial bubbles. But the president of Chicago Fed, Charles Evans, agrees with Mr. Ball’s views and states that raising the rates too soon would cripple the economic recovery and thus the Fed should keep them low until early 2016. The article reports that Mr. Ball notes that the Fed can afford to err on the side of too much stimulus rather than too little of it in order to guard against a deflationary spiral. He therefore warns against raising the short term interest rates in 2015 terming such move as imprudent. I agree that keeping the interest rates near zero will drive the unemployment rates lower than 5% and therefore keeping it low will be beneficial. The kind of unemployment the US is currently facing is majorly a cyclical inflation as the recession put most people out of jobs. While interest rates are an

Article Summaries Research Paper Example | Topics and Well Written Essays - 500 words

Article Summaries - Research Paper Example The Board of Regents also wanted to revitalize their education system to fill in the many job openings available in the state which needed certain educational attainments, which in turn could be potential in increasing economic growth in the state. The university plan has just started on July 1, 2012, so the article has no full list of results yet. The Board of Regents of the University System of Ohio made the change in the educational system so that their graduates would become more productive and also to fill the need for professionals in the state of Ohio, both in the business and education sector. Because the plan just started on July 1, 2012, not many results are out yet, but the prevention of high tuition fee increase, faster educational track, saving in school constructions, and inviting investors to generate funding in the universities were already started. The Board of Regents expects that when the changes have all started, there would be an economic growth in the state, more jobs will be filled in, and more students will become productive and better at their careers. The implications of the plan would be that more students can go to universities because the tuition fees are lower, and more will graduate on time and have jobs because the curricula would be more fitted to application in the real world and taught at a faster and more effective rate. The schools can also increase their funding because of additional investors, and their potential of being an economic strength can be released. It is recommended that the results of the changes be checked after one or more years of implementing so that the Board of Regents can see whether the changes made an impact on the labor forces of businesses in Ohio, in the universities’ school standards, and also of the students that graduate from Ohio
