Global Warming Essay Example for Free

Global Warming Essay Global warming pertains to the increase in temperature of the atmosphere based on the entrapment of gases that are emitted from activities on the surface of the earth. The increase in temperature is a direct result of the greenhouse effect, which involves heat that originated from the sun, which is entrapped within the atmosphere due to several factors. Scientists have determined that the atmosphere’s temperature has increased since the industrial revolution, which has maximized the use of chemicals in manufacturing various kinds of materials in industry. Global warming may result in regional changes in the weather, which will be more obvious if the weather were compared from one decade to another, and not on a daily basis. However, scientists have hypothesized that when the temperature of the surface of the earth has reached a highly critical level, such high temperature will cause severe and drastic changes to the atmosphere, affecting the oceans and will severely alter the weather patterns in a matter of years. Changes in the weather may include increasingly hot days and less cool days. The water levels will go down, exposing more land surface during the summer. Even higher latitude regions will be warmer by 40%. In addition, the amount the precipitation, be it rain or snow, will also increase, in the form of stronger storms and very intense typhoons and hurricanes. The El Nino events may also be more increase due to global warming. Global warming not only affects the weather, but it will also affect natural habitats. Higher levels of CO2 may facilitate the growth of forests, facilitating them to flourish and bloom. The warmer ocean waters will be helpful to fish and algae in the high seas. However, those organisms in higher elevations will find difficulty in surviving in warmer environments. Higher temperatures in oceans may kill corals, which are the nurseries for fishes and other aquatic organisms. For the human population, global warming may cause more incidents of infectious diseases such malaria, as well as systemic health problems such as heat stroke and respiratory diseases. Currently, the world is confused as society is ignorant of the detailed effects of global warming. Society is aware the summers are now longer and more intense and winters are envious of summer’s wrath, unleashing a fury that rivals the intensity of the heat. This is actually what global warming does. It confuses the world and now currently has also succeeded in confounding scientists. From a scientific point of view, global warming can be understood as a global environmental phenomenon which is characterized by an increase in the average temperature of the Earths near-surface air and oceans (Smith and Reynolds, 2005). There is certainly no doubt that global warming has a very detrimental effect on the environment as it causes rising sea levels and alters the amount and pattern of precipitation that a areas all over the world get (Gregory et al. , 2002). These environmental changes are also the projected causes of other ecological changes such as increases in the frequency and intensity of extreme weather events which in turn creates changes in agricultural yields, glacier retreat, reduced summer stream flows, species extinctions and increases in the ranges of disease vectors (Choi and Fisher, 2003).

Geographic Study of Mountain Area

Geographic Study of Mountain Area CHAPTER II STUDY AREA PROFILE 2.0 General: The study area (13858.83 ha) is a mountain range between River Pravara and River Mula Basin. The range started from western boarder at Ghatghar village and end eastern border at village Washere in the Akole tahsil, district Ahmendagar of Maharashtra state. The extent of study area is 19 ° 35 06.86 to 19 ° 30 13.08 N latitude and 73 ° 37 00.03 to 74 ° 04 24.65 E longitude. It covers parts of the Survey of India topographic sheet numbers 47 E/ 10, 11, 14, 15 and 47 I/ 2, 3. The depth and water-holding capacity of the soils are varied even if there is slightly change in slopes which is the one of the reason in the variation of forest land. The slope of the area is decreasing from NW to SE respectively and the height varies from 560 m to 1646 meters above mean sea level. Study area is distributed in the Sahyadri mountains (Western ghat) region of the Maharashtra state. Geologically this area formed from basaltic lava. Basalt rock prevent percolation of rainy, reservoir water in to underground zone. Due to rock type the soil cover is very shallow at the top of the mountain and increasing its deepness at foothill zones near water reservoirs. Basic Intrusive (Dykes) mainly found nearby this area. This are the approximate reasons of the shallow soil cover. Very shallow loamy, shallow clayey soil found on the moderate (1 °- 3 °) and stiff (3 °- 6 °) slope. Soil moisture impact on the amount of the vegetation cover with respect to soil type and slope. Therefore, North West and South zone have maximum vegetation cover compare to other land of the study area. It receives annual rainfall about 440.4 mm. The mean annual maximum and minimum temperatures are 39.80 C and 8.70 C respectively. Local tribal people engages with the agricultural activities at reclaimed land from forest area. Forestry is the second occupation after agriculture. 2.1 Geology: Study area is a part of Sahyadri Mountain Range (Western Ghat). Also called as Deccan Trap formed by basaltic rocks; amygdaloidal basalts form the bedrock. This area has shallow soil like loam, clayey; again divided in to sub types based on depth and slope classes. Overlying weathered and fractured rocks, resting on hard massive basalt. The basalts are nearly horizontal, separated by thin layers of ancient soil and volcanic ash (red bole). The basalt flows are nearly flat-lying (the sequence has a regional southerly dip of 0.5-1 °) and mainly belong to the Thakurvadi Formation (Fm) of the Kalsubai Subgroup (Khadri et al. 1988; Subbarao and Hooper 1988). The lithology of the area indicating that around 77.17 % area covered by 12-14 compound pahoehoe flows and some Aa flows (max 206m). Around 4.53 % by 2 compound pahoehoe flows (40-50m) and Megacryst compound pahoehoe basaltic flow M3 (50-60m) up to 3.26 %. Remaing 0.89% covered by 5 Aa and 1 compound pahoehoe basaltic lava flows (Max. 160m); 4-5 compound pahoehoe basaltic lava flows (Max. 150m), Basik Sill/Lava channels respectively. The regional stratigraphy of the Deccan basalts has been described by Beane et al. (1989), Khadri et al (1988), and Subbarao and Hooper (1988). Structural indices indicate the part of basic intrusive (dykes) in the part of noer-west and south-east. One fault line cross at the middle part of the study area. 2.2 Relief: Study situated at the middle of the tehsil Akole. It has horizontal shape and act like a natural water divider. Relief turn and fix the surface geographical landforms. The altitude of this area is varies from less than 640 meter (minimum) to 1646 meter (maximum). The formation of soil, natural vegetation cover and soil moisture conditions are totally controlled by the status of the relief. Contour lines demarcate the height of the study area above mean sea level. The Kalasubai (1646m) highest peak of the Maharashtra state located in the Akole tehsil. In the tehsil second highest peak Harishchandragarh (1422m) located in the south-west part of the study area. Relief decreasing toward to the Washere village of this mountain range. Drainage network flow depends on relief is explained in next point. 2.3 Slope: Slope of the study area calculated in degree (0 ° to 90 °) on the basis of contours. This slope of the area divided in to 7 classes. Gentle slope has up to 1 ° slope where water reserve and collected in dam. Soil depth, cover and types also depends on the nature of slope. Hill top and cliff sides has precipitous to very steep slope (12 ° to 90 °). At foothill slope moderate to steep (1 ° to 12 °) zone has maximum forest cover in north-west and south-west direction. Eroded material on the top hill concentrating on the foothill slopes and favourable for soil formation. That is why the in this area soil moisture, soil depth and vegetation cover found more than other zone. Soil types and different characteristics has been elaborated in the next point. 2.4 Drainage: Network of drainage is developing continually and it’s responsible for the different landform creation. Relief controlled the drainage flow and streams erode land surface in to different geographical landform features. Relief and streams has strong correlation. Study area has an origin point of the main river Pravara. River flows from north-west to north-east direction. This river has main and minor dam. Bhandardara is main dam situated on river Pravara, which is an important land-cover feature in study area. At the time of robust forest change analysis this water body play an important role. Soil moisture depend on drainage network and water reservoirs after rainy season. It made difference in the type of vegetation cover from dense forest to open scrub land. Drainage pattern related to slope and slope related to forest growth has been explained in detailed in the next point. 2.5 Soil: The growth and reproduction of forest cannot be understood without the knowledge of soil. The soil and vegetation have a complex interrelation because they develop together over a long period of time. The vegetation influences the chemical properties of soil to a great extent. The selective absorption of nutrient elements by different tree species and their capacity to return them to the soil brings about changes in soil properties (Singh et al. 1986). Soil element is one of the most important biophysical matter. Concentration of elements in the soils is a good indicator of their availability to plants. Their presence in soil would give good information towards the knowledge of nutrient cycling and bio-chemical cycle in the soil–plant ecosystem (Pandit and Thampan 1988). Generation of soil is depend on geology, topography, time span, climatic conditions, organic and inorganic factors, etc. Forests in general have a greater influence on soil conditions than most other plant eco system types, due to a well-developed ‘‘O’’ horizon, moderating temperature, and humidity at the soil surface, input of litter with high lignin content, high total net primary production, and high water and nutrient demand (Binkley and Giardina 1998). Study area is a hilly zone, soil is very shallow at the top-hills while excessively drained loamy soil (a rich soil consisting of a mixture of sand and clay and decaying organic materials) found at steep slopes north-west direction. Shallow well drained clayey soil and slightly deep excessively drained loamy soil found over moderate to gentle slope respectively. Clay soils, are made up of very fine, microscopic particles. These tiny particles fit together tightly, resulting in tiny pore spaces between them. The tiny pore spaces allow water to move through them, but at a much slower pace than in sandy soils. Clay soils drain quite slowly and hold more water than sandy soils. Loams soil capacity of maximum water holding (MWHC) approximately 0.18 inches of water per inch of soil depth, and clays hold up to 0.17 inches of water per inch of soil depth. However, soil types, soil elements, soil depth depends on the geology of the study area, explained in next point. 2.6Population and economic activities: Humans being living surrounding this area most are the tribal population. Primary economical activities including shifting cultivation, fishery, 2.7Spectral properties of plants in the forest: (1st ch) Interaction of radiation with plant leaves is extremely complex. General features of this interaction have been studied but many spectral features are yet unexplained. Gates et al., (1965) are considered pioneers, who have studied spectral characteristics of leaf reflection, transmission and absorption. Optical properties of plants have been further studied to understand the mechanisms involved by Gausman and Allen (1973), Wooley (1971) and Allen et al., (1970). It is the synthesis of the parameters like reflection of plant parts, reflection of plant canopies, nature and state of plant canopies and Structure and texture of plant canopies, which will be required to fully understand the remote sensing data collected from space borne and aerial platforms. They have been attempted for crop canopies through the development of models but not yet fully achieved. It will be initially required to discuss the electromagnetic spectrum and its interaction with vegetation canopies. Subsequent factors affecting the spectral reflectance of plant canopies with its possible applications in remote sensing technology would be discussed. The vegetation reflectance is influenced by the reflectance characteristics of individual plant organs, canopy organization and type, growth stage of plants, structure and texture of the canopies. The synthesis of the above four aspects provides true reflectance characteristic. However, various authors without fully achieving models to determine vegetation reflectance characteristics have studied effect of individual parameters. 2.6.1 Nature of the Plant: Numerous measurements have been performed to evaluate the spectral response of various categories of plants with a spectrophotometer (Fig. ***). For a plant in its normal state i.e., typical and healthy the spectral reflectance is specific of the group, the species and even of the variety at a given stage in its phenological evolution. The general aspects of spectral reflectance of healthy plant in the range from 0.4 to 2.6  µm is shown in figure ****. The very abrupt increase in reflectance near 0.7  µm and the fairly abrupt decrease near 1.5  µm are present for all mature, healthy green leaves. Very high; further in the far infrared >3.0  µm. Thus, the typical spectral curve of plant is divided into three prominent zones correlated with morphological characteristics of the leaves (Gates, 1971). 2.6.2 à ¯Ã¢â€š ¬Ã‚  Pigment Absorption Zone: The important pigments, viz. chlorophyll, xanthophylls and carotenoids absorb energy strongly in ultraviolet blue and red regions of the EMR. The reflectance and transmittance are weak. The absorbed energy of this part of this spectrum is utilized for the photosynthetic activity (Allen et al. 1970). 2.6.3 Multidioptric Reflectance Zone: In this zone, the reflectance is high, while the absorbptance remains weak. All the unabsorbed energy (30 to 70% according to the type of plant) is transmitted. They reflectance is essentially due to the internal structure of the leaf and the radiation is able to penetrate. The reflectance from internal structure is of physical more than chemical nature. Apart front the contribution of the waxy cuticle, the magnitude of the reflectance depends primarily upon the amount of spongy mesophyll. 2.6.4 à ¯Ã¢â€š ¬Ã‚  Hydric Zone: Amount of water inside the leaf affect the pattern of spectral reflectance with water specific absorption bands at 1.45  µm, 1.95  µm and 2.6  µm. Liquid water in a leaf causes strong absorption throughout middle infrared region. Beyond 2.5  µm the reflectance becomes less than 5% due to atmospheric absorption and beyond 3  µm the vegetation starts acting as quasi blackbody (Gates et al., 1965). There are numerous factors either internal of the plant or external coming from the environmental conditions have an influence on the specific spectral reflectance. The above descriptions are true only for a normal, mature and healthy vegetation. The factors which affect the spectral reflectance of leaves are leaf structure, maturity, pigmentation, sun exposition, phyllotaxis, pubescene, turgidity (water content) nutritional status and, disease etc. Important factors are pigmentation, nutritional status, anatomy of leaves and water content. While, sun exposition and phyllotaxy affects the canopy reflectance, phenological state and disease are linked to the primary factors affecting the spectral reflectance (Wooley, 1971). 2.7Spectral vegetation indices: Radiant energy intercepted by a vegetative canopy is primarily scattered by leaves either away from the leaf surface or to the leaf interior. The scattered radiation is reflected, transmitted or absorbed by leaves. The partitioning of radiation a reflected, transmitted or absorbed energy depends on a number of factor including leaf cellular structures (Gates et al. 1965; Kfipling, 1970; Woolley, 1971), leaf pubescence and roughness (Gausman, 1977), leaf morphology and physiology (Gausman et al., 1969 a, b; Gausman and Allen, 1973; Gausman et al., 1971) and leaf surface characteristics (Breece and Hommes, 1971; Grant, 1985). Leaves are not perfectly diffuse reflectors but have diffuse and specular characteristics. Leaf transmittance tends to have a non Lambertian distribution, while leaf reflectance is dependent on illumination and view angles. Knowledge of soils radiation interaction with individual leaves is necessary for several reasons like special to interpret and process remotely sensed data. Typical reflectance and transmittance spectrum of a individual plant leaf indicate three distinct wavelength regions in interaction: visible (0.4-0.7  µm), near infrared (NIR) (0.7-1.35  µm) and mid infrared (mid IR) (1.35-2.7  µm). Thus the typical spectral curve of plant is divided into three prominent zones correlated with morphological/anatomical/physiological characteristics of the leaves and these are Pigment Absorption Zone, Multi-Dioptric Reflectance Zone and Hydric Zone, etc. The analysis of all remotely sensed data involves models of many processes wherein the EM radiation is transformed (the scene, atmosphere and sensor) and whereby inference is made about the scene from the image data. The most common strategy for relating remote sensing data to vegetation canopies has been via the correlation of vegetation indices with vegetation structure and functional variables. This simple empirical approach has yielded substantial understanding of the structure and dynamics of vegetation at all scales. These indices are capable of handling variation introduced in a scene due to atmosphere or sensor and vegetation background influence in low vegetation cover areas. The capacity to assess and monitor the structure of terrestrial vegetation using spectral properties recorded by remote sensing is important because structure can be related to functioning, that is to ecosystem processes that are ultimately aggregated up to the functioning of the local-regional-global level of ecosystem. The categorization of the various spectral indices in to approximately five types. Such as Ratio Indices, Vegetation Indices, Orthogonal based Indices, Perpendicular Vegetation Indices and Tasseled Cap Transformation, etc. Remote sensing of cropland, forest and grassland involves the measurement of reflected energy of component in the presence of each other. The development and usefulness of vegetation indices are dependent upon the degree to which the spectral contribution of non-vegetation component can be isolated from the measured canopy response. Although vegetation indices have been widely recognized a valuable tools in the measurement and interpretation of ‘vegetation condition’ several limitation have also been identified. They are related to soil brightness effect and secondary soil spectral deviations. The use of site specific soil lines reduces soil background influence. In this context SAVI, GRABS and PVI holds greater promise in low vegetated areas. The vegetation indices are simplified method to extract information about vegetation parameter from multispectral data however, their use in spectral modeling needs to be studied in context of spectral dynamics of earth surface components. 2.8Resume`: Forest cover is an important natural resource for the environment and socio-eco on the surface of the earth. It can bridge the gap between nature and human beings conflicts. Changes in the forest land increase the imbalance in the ecosystem, climatic conditions, temperature, land degradation, drought prone zones, soil erosion, depending manmade activities, etc. The living tribes in the mountain hill as well as foot hill area utilized forest material for their domestic usages. Therefore, the objectives of detection and delineation of the forest land by using ordinary classification methods have been outlined in the present study. The methodology has been outlined in this chapter. The Landsat-5 TM and Landsat-7 ETM+ dataset has been suggested as a source of information to achieve the objectives of the study. The basic knowledge regarding spectral properties of the forest and physiographic elements as well as spectral vegetation indices area has been proposed for the second chapter to m ake information base study for image analysis, classification and interpretation in the next chapters. *********

In 1959 Professor JÃ ©rome Lejeune proved that Down's syndrome is a chromosomal irregularity.Parents in that time were ashamed of their children with disabilities.In 1944 kids with disabilities did not have the right to have an education. Not until 1971 it was recognized that it should be legal for people with learning disabilities to get an education.Life expectancy for people with Down syndrome has heightened dramatically in modern decades from 25 in 1983 to 60 today. People with down syndrome have an increased risk for certain medical conditions such as heart disease,brain atrophy and learning disorders.(downs-syndrome association) Down's syndrome is not a disease and therefore people with Down syndrome do not suffer nor are they victims of their condition.Down Syndrome is a natural disorder coming from a chromosome defect. It is a genetic condition in which a person has 47 chromosomes instead of the usual 46. Which causes mental impairment and physical deformity.For example short stature , broad facial profile and weak muscle tone.It occurs in approximately one in every 800 live births.It is the most frequently occurring chromosomal disorder. Down syndrome is not related to race, nationality, religion or socioeconomic status.(medline plus) Children with Down syndrome are normally smaller, and their physical and mental improvements are slower compared to children who are unaffected.Some of the physical features in children have flattening of the back of the head, slanting of the eyelids, small skin folds at the inner corner of the eyes, depressed nasal bridge, slightly smaller ears, smal... ... in positive ways, particularly during adolescence.

Parents should learn to help a person with Down syndrome deal with frustration and anger. Although, it is important to encourage independence.

Sex Offender Laws and Wrongful Convictions Essay -- Argumentative Ess

Sex Offender Laws and Wrongful Convictions The laws for sex offenders should be changed for many reasons. This is a very controversial subject, and tempers flare easily and often for good reason. Due to the plethora of opinions on this subject it is hard to determine what is right and what is wrong. The very same government sending teenagers to school together as a group and teaching them about safe sex is the same government that is bringing charges against them for practicing sex. Not only that but they are labeling them as sex offenders for the rest of their lives. How confusing this must be to the young people of America today. So many young people are finding this out the hard way by being accused of a sex offense for being with a person of their own age group, their peers. Consensual sex by teenagers experimenting is an activity that is labeled by most states as sexual assault, statutory rape and/or child sexual abuse. This felony crime, in most states, is also accompanied by registering as a sex offender for the rest of a person’s life if convicted. Growing up in the 60’s, it was common and acceptable for a sixteen year old to date a nineteen or twenty year old. It is a good thing these laws were not in effect then, because most of the young people being accused today would have never been born. Their parents would either still be in jail or unable to afford to have children due to the fact that a registered sex offender cannot find decent paying employment. â€Å"No one will hire a person labeled a sex offender no matter what the situation, clearly a violation of human rights.† (Laurie Peterson July 27th 2007) Federal legislation expanded the release of criminal records reports under the fair credit reporting... ... and Hayley Mitchell Haugen.

Every Child Deserves a Blissful Life. Essay -- child abuse, parents, ab

Most parents and other caregivers do not intend to hurt their children, but the effect on the child defines abuse, not the motivation of the parents or caregiver. Abuse comes in many forms and the statistics prove how alarming the issue is, â€Å"Every year there are 3.3 million reports of child abuse involving nearly 6 million children†.(Source F) It is immensely difficult to imagine what would make adult use violence against a child. Parents have the responsibility to nurture, raise, and discipline an offspring. However, the definition of the term discipline is differently interpreted by parents. Children will misbehave and teaching the difference between right and wrong and not resulting to forms of abuse .Some go to extreme measures to discipline a child, thus creating deep physiological problems. Child abuse needs to be prevented and the government should intrude to insure the safety of the children and of future generations. Caused by different things, abuse comes in many forms and can be preventable. Verbal and emotion abuse often coincide with physical abuse and neglect. â€Å"Child abuse usually starts with a desire for the abuser to have control†.

Discipline is necessary in parenting however a line needs to be drawn where the discipline stops and the abuse begins. Any form of abuse is horrifyingly wrong and needs to cease to a stop. Children need to be protected from the monsters that hurt them. â€Å"1,545 children died as a result of abuse and neglect†. (Source F) There is no need for that many deaths.

A read-write learner absorbs information through written forms: lists, reading texts or handouts, detailed note taking, power points, and additional resources like paper or online articles about the subject. Student A also uses some of the strategies of this style with the additional research on the topic, multiple proof reading of written content, and reading of all assigned texts or handouts. Review of the learning strategies of both the read-write and the inesthetic learning styles shows helpful strategies not currently used by Student A. This student can also benefit by incorporating several learning strategies from each style. The kinesthetic strategy of relating the information to their own life experiences and finding real life examples would help Student A to retain and recall information as it is attached to real life references the student has already internalized. Using the read-write strategies of rewriting information several times and turning the content of a graph or diagram into a written summary would help Student A clarify and retain nderstanding of that content. Using the VARK Learning Style Assessment is a helpful tool for any learner. It gives helpful information that allows the student insights into how they learn and offers strategies to make the most of that learning style and avoid the problems that can be associated with that style. It is also very helpful for a student to understand that there are other learning styles and be aware of the focus of those learning styles. This aids in translating information given in another style in to the student’s style for optimum learning and also helps the tudent translate their style to accommodate the learning style of another when teaching information.

An Analysis of the Evolution of the E-Business in America Essay

Economic transactions have taken a toll of revolutions and evolutions from the most historic barter deals to currency minting to bank-to-bank transactions, and finally, electronic business. Undeniably, the phenomenal effect of information technology to the lives of common man has caught the complexities of all branches of science and economics in a single matrix. Similarly, it has extinguished spatial boundaries in the business arena. Upon the advent of the accessibility of the internet or the World Wide Web to the public in 2004, it has been deemed that e-commerce will shortly follow through. So thus soothsayers and journalists manifest into the world this forecast. Company websites and internet servers sprouted like wild mushrooms here and there, flooding the virtual world with what’s it’s’ people cannot usually find for themselves. A unique gadget which can be found nowhere at a shopping mall is now easy to find at Ebay or Amazon. om, or shopping for clothes can also be done via ordering online, and sending emails or conversing with another entity half an earth away through instant messengers now became a common activity to the technologically savvy. A worldwide acknowledgment of this phenomenon has now slowly shifted every human paradigm there is. This evolutionary way of business ‘anytime-anywhere scheme’ or transacting across the planet in only a matter of seconds has put le verage to the face of business vis-a-vis human technology. E-business or e-commerce, also known as EC, has now penetrated all elements of life, particularly the world of commerce and economics. Today, e-business is now the most preferred way of dealing with and between firms. In the fields of traveling, media, logistics, telecommunication, and manufacturing, as identified by Horsti, Tolonen and Brannback (2003) in their study of five electronic business models, it showed that operating a business backed by ecommerce and proper management of personnel skills and customer relationships is a critical success factor (CSF) and always has a direct correlation to business success. This gives light to the logic as to why bankers and corporations alike have resorted to sending orders and invoices via internet instead of sending messengers or bulky packages to each other and wait for days before the same arrives at each other’s doorstep. On an individual basis, transacting with another online instead of going to a bank and undergoing the tedious process of lining-up and filling out slips and various withdrawal or deposit forms has been the hip. Online credit card transactions has also been the trend nowadays especially to the technologically savvy. As Moslein (2001) would argue, the rise of ecommerce has extinguished traditional boundaries and spatial constraints of conducting business. So what really is it behind e-business and what makes everyone indubitably caught up with this intertwining net of transactions? In this paper, the aforementioned is put to a limelight along with a detailed analysis of the e-business phenomenon. A projection as to how e-business in America will perform in the short-run is also forecasted. Pros and cons of doing e-business as well as important dissections of it are also included herein. The first part of this paper shall serve as a guideline as to how discussion will flow and what models and methods were used in shedding light to the subject matter at hand. It also serves as briefer to the latter portions which delve deeper to the subject matter. The latter portions shall plainly consist of the author’s own views with regard to the topic, however, with sources to buttress proof of claims. The summary and conclusions are second to the last parts before providing a list of references used in this research. Statement of the Issues/Problems The dawning of the internet and the birth of ecommerce in which e-business arose forthwith has also given birth to online corporations and rebirth to traditional enterprises. However, the new age technology has also given birth to various risks and opportunities for misers to tamper with the gifts of technology to the disadvantage of those who are faithful in their dealings. In this regard, the primary thrust of this paper is to analyze the gradual paradigm shift of business in America to the modern e-business taking into consideration the management decisions of enterprises vis-a-vis the costs and risks in engaging into e-business. Further, this paper rests with the issue on how ecommerce evolved to what it is today. Given these matters, the ultimate question this paper aims to answer is: Why do businesses continue to prefer to do e-business despite online security threats and risks? Hypothesis E-business is a response of various industries to the market forces affecting it, and amidst costs and risks, the benefits of e-business to enterprises prove to shape corporate success, help industries maximize benefits and positively affect the entire business industry as a whole. Methodology This paper is a result of a collaboration, compilation, corroboration and interpretation from various sources of information gathered mostly through the internet. Various theories in economics and business management are also used to prove certain stands pertinent to the subject matter. The author has also included newspaper articles and opinions from renowned columnists all of which can also be accessed through the internet. The said sources were streamlined for this purpose of incorporating into this subject matter all indispensable elements of e-business. It is important to highlight that this paper is not to measure e-business per se because of the very volatility and fast speed of growth and advancement of the e-business itself. As stated by the Organisation for Economic Co-operation and Development (OECD), measuring e-business and quantifying the elements of convenience and easy access to information is impossible given the current fast-changing nature of the market (OECD, 1998). Hence, this paper has enumerated the costs and benefits instead and weighed both in the light of the evolution of e-business to the stage. Degree of Reliance of Statistical Data/Literature Search The author has chosen only those sources which are strongly correlated and are very pertinent to e-business. For statistical data, there is an interim degree of reliance from high to medium degree, since statistics were conducted by professional research institutions and quoted from high grade literature. With regard to articles and sources, most of the studies consulted where products of doctorate and master’s degree holders who are expert in this field notwithstanding those who gave garnered distinctions (i. e. Nobel Prize, Pulitzer, etc. in the field of economics. Therefore, there is a high level of reliance on their studies. A Description of the Research Design This paper is purely research based and one which does not involve interpretation of raw statistical data. Due to the broad and constantly changing nature of e-business, a survey of the entire America is implausible. Thus, it is best to resort to data that have been gathered by reliable research institutions concentrating on the same subject matter. The literatures used herein are mostly second-hand ones and are retroactive in its nature such that theories used are identified as paradigms. Despite being cited and further cited in various citations, the theory is not eroded. Thus, citations of the same coming from other citations, or a chain of citations in one citation, are valid. It is also important to note that despite the varying nature of the sources used in this paper, the discussion shall not be deprived of important knowledge as regards the subject matter. Models Followed The paper follows three specific models in economics: the law on supply and demand, the model on cost-benefit analysis (CBA) and the game theory. This is because these three easy-to-understand theories are also the primary considerations of CEOs in choosing management decisions and doing other management strategies. In accordance with the objectives of this paper, various researches shall also be inculcated herein to give various theories and conceptions an equal footing as regards the topic. As a clarification, there are no current researchers who have analyzed the nature of e-business extensively and collaboratively using the aforementioned theories. Therefore, literature reviews are primarily based on historical findings on the evolution of e-business, analyses of various researchers on the nature of economics vis-a-vis ecommerce and not on concurrent ecommerce theories. This is also because majority of ecommerce theories are offspring of the theories on economics. Moreover, ecommerce theories may be relevant to the subject matter but are not directly connected to the topic such that answers to the research questions as aforementioned were more founded by basic economic theories rather than the specialized ecommerce theories on web-hosting and online selling.
