Traditional Hydroponics Systems free essay sample

Aeroponics is the process of growing plants in air or mist environment without the use of soil. Not to be confused with hydroponics or peeponics, aeroponics is the process of spraying or fogging the roots of the plants with a nutrient solution. The plants are usually housed in troughs, tubes or foam, with the leafy part of the plants separate from the roots. Moreover, the roots are usually fully exposed and constantly sprayed with micro bursts of atomized water. Why aeroponics are used? Since plants have access to oxygen 24/7 they generally will experience faster growth than conventional means Water and nutrient used efficiently Less need for nutrients and water than traditional hydroponics systems no need to worry about weeding takes up very little space Can be made as a DIY project It uses considerably less energy and water than traditional agriculture. systems can be built as a DIY project Disadvantages of aeroponics you will need to provide nutrients as with hydroponics requires electricity for small pumps and timers as with hydroponics, you will need some form of competency to run system can be an expensive system to buy In the beginning you need to monitor the water Root crops and trees are much more difficult to grow Final words on aeroponics Aeroponics has been tested to grow cleaner, more consistent herbs like burdock at the University of Arizona’s College of Agricultural and Life Sciences.

Greens can become contaminated with soil pathogens and bacteria like e.coli, but aeroponics greatly reduces these risks. That is what all the research says. Practically, aeroponics would seem a perfect fit for also growing small potatoes. Hydroponics give more harvest but smaller and fewer tubers than aeroponics. However, from the pitcher one can see how much easier harvesting  the potatoes will be over hydroponics or traditional grown potatoes. Types of Aeroponics Low-pressure units High-pressure devices Commercial systems The modern 21st century aeroponics are Contemporary aeroponics Aeroponic bio-pharming Large scale integration of aeroponics Hydroponics is a method of growing plants in a nutrient solution without soil. The plants, which are usually grown in shallow trays, are supported by an inert growing medium such as gravel, mineral wool, or perlite. Greenhouse is an ideal place for hydroponic gardening. Temperature and humidity can be maintained in the growing range that is best for plants, creating a nearly perfect environment. Benefits of Hydroponics *No soil is needed for hydroponics. *Lower water costs. * Lower nutrition costs. *No nutrition pollution is released into the environment because of the controlled system. *Stable and high yields. *Pests and diseases are easier to get rid of than in soil because of the container’s mobility. *It is easier to harvest. *No pesticide damage. *Plants grow healthier. *It is better for consumption. Disadvantages Without soil as a buffer, any failure to the hydroponic system leads to rapid plant death. Techniques The two main types of hydroponics are Solution culture Medium culture. The three main types of solution cultures are static solution culture continuous-flow solution culture Aeroponics There are two main variations for each medium are sub-irrigation top irrigation

Spanish Influenza essays

Spanish Influenza essays Influenza is and acute infectious and Contagious disease sometimes becoming Pandemic. It is characterized by an inflammation of the mucous membrane of the respiratory tract. Epidemics of this disease have been recorded as early as 1510. The Influenza pandemic of 1918 killed 600,000 people in the United States and more than 25 million people worldwide. It was called the Spanish flu because of a large outbreak of the disease that occurred in Spain in 1918. The origin of this influenza variation is not exactly known it is thought to have begun in china in a rare genetic variation of the influenza virus. The virus however may have originated among US soldiers in Kansas; about 500 men there were infected among 48 were listed as having pneumonia. Those who survived the epidemic carried the disease to Europe where in the summer of 1918 over one and one half million U.S. soldiers were sent to fight in the First World War. Whatever its origin by September 1918 the virus had spread to the civilian population of America It first reached epidemic proportions in Boston and then spread to New York, Philadelphia and beyond. In July 1918 Philadelphias Bureau of public health has issued a statement about Spanish Influenza. But health officials had not listed influenza as a reportable disease this denial of the danger of what was happening lead to people taking foolish risk. On September 28, 1918 a 4th Liberty Loan Drive parade was attended by 200,000 people and since Influenza is spread by breathing within days of the parade 635 new cases of the virus were reported and on October 6 289 people died. Most of the cities doctors and nurses were in Europe to support US involvement on the war there. Many people in Philadelphia died because they did not get proper medical treatment. The City sent out open trucks called death wagons to pick up corpse from wooden boxes on front porche ...

Adjectives vs Adverbs for ACT English Grammar Rule

Adjectives vs Adverbs for ACT English Grammar Rule SAT / ACT Prep Online Guides and Tips You may recall the good ol’ days of elementary school when you learned about adjectives and adverbs. If you had realized that you would have to know about these parts of speech for the ACT, perhaps you would have paid better attention instead of daydreaming about Nickelodeon and The Disney Channel. Don’t worry. If you’ve forgotten or never learned about these parts of speech, I’ll teach you everything you need to know about them for the ACT English section. In this post, I'll do the following: Define an adjective. Define an adverb. Review the comparative and superlative forms of adjectives. Explain how adjectives and adverbs are tested in ACT English. Provide practice questions to test you on what you've learned. What Is an Adjective? Adjectives modify nouns or pronouns. Here's an example: The movie was boring. The word "boring" is the adjective because it modifies the noun "movie." Check out one more example sentence with an adjective: The diligent student was admitted to the college of his dreams. The word "diligent" modifies the noun "student." Adjectives describe or provide more information about a noun. Now, let's define an adverb. What is an Adverb? In elementary school, you may have learned that adverbs modify verbs, but that's not all. Adverbs modify verbs, adjectives, or other adverbs. This is an example of an adverb modifying a verb: The dancer moved gracefully. The word "gracefully" modifies the verb "moved." Check out this sentence with an adverb modifying an adjective: The reading comprehension passage was incredibly boring. The word "incredibly" modifies the adjective "boring" that modifies the noun "passage." And, finally, this is a sentence with an adverb modifying another adverb: When I'm not in a hurry, I walk extremely slowly. The word "extremely" modifies the adverb "slowly." The word "slowly" modifies the verb "walk." You may have noticed the adverb form is typically created the same way. Adverb Construction Adverbs are usually formed by adding "ly" to the adjective. For adverbs that end in "y," the adverb is formed by adding "ily." Here are some examples: "quick" becomes "quickly," "soft" becomes "softly," "close" becomes "closely," and "hasty" becomes "hastily." So if you say that somebody"talks slow" or "drives careful," you're making a grammar error. You should say, "talks slowly" or "drives carefully." How are adjectives and adverbs tested on the ACT? Adjectives vs. Adverbs on the ACT On the ACT, adverbs and adjectives will be switched with one another. Often, you will be given a pair of underlined words and the first should be an adverb (modifying the adjective) and the second should be an adjective. Here is an example: Unfortunately, the lead performer in the musical is an amazingly poorly singer. A. NO CHANGE B. amazing poorly C. amazingly poor D. amazing poor In the sentence, "amazingly" modifies "poorly." The word "poorly" modifies the singer. Because "singer" is a noun, "poorly" should be in the adjective form. Only adjectives can modify nouns. Because "amazingly" modifies an adjective, it should remain in the adverb verb. The answer is C. Some sentences will use an adjective in the place of an adverb or vice versa: The powerfully summer sun beat down on them. It was the sun that was powerful, not "summer." Because only an adjective can modify a noun, "powerfully" should be in the adjective form. This is the correct version of the sentence: The powerful summer sun beat down on them. How should you go about figuring out adjective vs. adverb questions on the ACT? Strategy Determine what word an adjective or adverb is modifying. Then, determine the part of speech of the word that is being modified to check to see if the adjective or adverb is being used correctly. Adjectives can only modify nouns and adverbs can only modify verbs, adjectives, or other adverbs. Make sure that adjectives are in the adjective form and adverbs are in the adverb form. Apply these tips to an adjective vs. adverb question from an actual ACT. Actual ACT Examples Try to correctly answer this adjective vs. adverb question. On each wing, all flighted birds have ten primary flight feathers, each one shaped slight different. F. NO CHANGE G. slight differently. H. slightly differently J. slightly more different Explanation: First, we see that both underlined words are in the adjective form. Next, we have to determine the function of each word in the sentence. Is each word being properly used as an adjective? Let’s start with â€Å"different." What is â€Å"different† modifying? How the feathers were shaped. â€Å"Shaped† is a verb. Therefore, â€Å"different† should be in the adverb form, â€Å"differently." What is â€Å"slight† modifying? The adverb â€Å"differently." Therefore, â€Å"slight† should also be in the adverb form. The answer is H, â€Å"slightly differently." Now, let's take a look at another issue tested on the ACT that involves adjectives and adverbs. Comparatives Vs. Superlatives Comparatives The comparative form of an adjective is formed by adding "er" to the word or "MORE" + the adjective. Examples of comparatives include "stronger," "lighter," and "more interesting." Never use "more" with the "er" form. You can't write "more stronger" or "more lighter." The comparative form is only used when you are comparing two things. Typically, you use the "er" form for words with one syllable and "more" + adjective for words with two or more syllables. One exception is that two syllable words that end in "y" tend to use the "er" form. Examples: "funny" becomes "funnier" and "busy" becomes "busier." Here's an example of a comparative being used correctly: Macs are easier to use than PCs. The comparative "easier" is being used to compare two things: Macs and PCs. So what form do you use to compare three or more things? Superlatives The superlative form of an adjective is formed by adding "est" to the word or "MOST" + the adjective. Examples of superlatives include "strongest," "lightest," and "most fascinating." You can never use "most" with the "est" form. It's incorrect to write "most funniest" or "most strongest." The superlative form is only used when comparing three or more things. Typically, words with one syllable use the "est" form and words with two or more syllables use "most" + adjective. This is an example of a correctly used superlative: Of all the computer brands, Macs are the easiest to use. When using "all" and not specifying a number, it's implied that you're talking about more than two so you should use the superlative form. Check out this example of a superlative being used incorrectly: Between John and Suzy, Suzy is the quietest. Remember that the superlative can only be used when comparing three or more things. There are only two in this sentence: John and Suzy. To fix the error, "quietest" should be changed to the comparative form, "quieter." How does the ACT test your knowledge of comparatives and superlatives? Comparatives and Superlatives on the ACT The ACT tests proper construction of comparatives and superlatives. You must know that comparatives are only used for comparing two things and superlatives are used for comparing three or more. Here are some tips to help you solve comparative and superlative questions on the ACT. Strategy Comparative and superlative rules are relatively basic. Remember this information and you should be able to correctly answer any ACT English question about them. If a comparative is underlined, make sure only two things are being compared. Never use "more" with the "er" form. Use the "er" form for one syllable words. If a superlative is underlined, make sure three or more things are being compared. Never use "most" with the "est" form. Use the "est" form for one syllable words. Use your knowledge of comparatives and superlatives to answer this real ACT English question. Actual ACT Example Here is a comparative/superlative question taken from a real ACT. The two principal types of kayaks are the easily maneuverable white-water kayak and the largest sea kayak. F. NO CHANGE G. very biggest H. more large J. larger Explanation: Because the word underlined is in the superlative form, we need to check to see if the superlative form is being used correctly. What is being compared in the sentence? The white-water kayak and the sea kayak. Only two things are being compared, so you have to use the comparative form. The sentence even says, â€Å"The TWO principal types of kayaks." Also, â€Å"large† is a one syllable word so you should use the â€Å"er† form instead of â€Å"more large." The answer is J. Here are some tips to help you answer all questions relating to adjectives and adverbs on the ACT. General Strategies for Adjectives and Adverbs on ACT English #1: If an Adjective or Adverb is Underlined, Make Sure the Word is Being Used Correctly On the ACT, adjectives and adverbs will often be placed next to each other and both words will be underlined. Make sure that adjectives are in adjective form and adverbs are in adverb form. #2: Determine the Part of Speech of the Word that the Adjective or Adverb Is Modifying Determine if a word is an adjective or an adverb by identifying the part of speech of the word it modifies. Adjectives modify nouns and adverbs modify verbs, adjectives, and other adverbs. #3: If a Comparative or Superlative Is Underlined, Make Sure the Word Is Being Used Correctly Comparatives Comparatives only compare two things. Proper comparative structure is the "er" form or "MORE" + adjective. Never use "MORE" with the "er" form. Use the "er" form for one syllable words. Superlatives Superlatives compare three or more things. Proper superlative construction is the "est" form or "MOST" + adjective. Never use "MOST" with the "est" form. Use "est" for one syllable words. Additional Practice I created these realistic practice problems to test your knowledge of adjectives and adverbs on the ACT. Enjoy! 1.

How have African-Americans Worked to End Segregation, Discrimination, Essay

How have African-Americans Worked to End Segregation, Discrimination, and Isolation to Attain Equality and Civil Rights - Essay Example With some clever and much-needed moves, they have come out of the stigma that gauged people based on their skin color. This is no more a scenario in US. These people have broken the hard chains and have come out of the discrimination, segregation and isolation. Not only have they come out of the problems surrounding them but have also attained equality in all terms as well as civil rights (Turner-Sadler, 2009, p. 4-11). One of the most important things that played a major role in the fight against discrimination is the passing of the Civil Rights Act of 1964. This particular act served as a saving grace for the people as it prevented discrimination on grounds of race, color, national origin or religion among the people. This stand was practiced in both normal activities in the country as well as for employment purposes. Afro-Americans successfully found their way to the top in all sphere of life, be it politically, socially as well as economically. After the Second World War, the Afr ican-Americans moved to some of the commercial cities in the northern and western parts. Usually, the black population is found to be more in the Southern regions. In course of time, the people started moving to other areas where opportunities are more and were a good platform for education was found. This segregation happened in a smooth manner and was made possible by the Civil Rights Act (Wynn, 2010, 30-55). There are lots of aspects that led to the upbringing of the Afro-Americans and one of the most important of all is their political influence. They came to know the importance of attaining political status and worked towards it. In few years, there were lots of African-American leaders in US. Intensity of support is more now and US now boasts of an African-American President at its realm. The first step towards the infusion of African-Americans into the political scenario took place in a slow yet steady manner that paved way for greater stability. Colburn and Adler (2001, pp. 45-75) points out that the political influence that the African-American population gained paved way for development. Richard Hatcher, an African American became the mayor in 1967 which was the beginning of the better phase for the group. With this move, came about a sea of positive changes in the US. Thus through a strong political footage, the African-Americans gained civil rights. Followed by the political affluences came the social status and other perks associated with it. Earlier, discrimination was found in all spheres of life right from jobs, positions and education as well. One of the most dreaded forms of discrimination that is found even now in some parts of the US is that of the employment discrimination. Some sort of discrimination will lead to a lot of adverse situations in the country. If there is no proper employment opportunity for the group then there will not be any sort of developments which may keep that particular society in darkness. In due course of time, thi s may even affect the country at large. There seems to be a significant development in terms of economy as well among the black population. The African-Americans have come to realize the importance of education, political and social status. Conrad (2005, p. 341) rightly points out that there has been a great development in the economical aspect with relation to the African population in America. One of the most important aspects that led

DropBox Case Essay Example for Free

DropBox Case Essay Dropbox was created in 2007 and launched to the public a year later. It was founded by Drew Houston and Arash Ferdowski; who were classmates together at MIT in the early 2000’s. The created a product that allows you to sync you computers together by using a cloud to share files between the different computers. At the time of creation there were existing products in the market but they believed that they created a product that would simplify the process as well as make it secure and reliable for the customers. Their plan was to differentiate themselves form their competitors based off these factors. For a customer of Dropbox it allows them to easily and reliably share files between their computers or devices. They believed that the existing products were unreliable and would only allow u to share a certain amount of files. Their product would be reliable and easy to use for the customers. They would also get a free 2G worth of space or could but additional space if they needed to. This is something seen by a few competitors but not all of them. They also created a product that can be used for both business and personal use. Dropbox will do something that also differentiates itself form their competitor. They will use Amazons server to provide the customers space the store files. This will be rented from Amazon and will drastically decrease the amount of money they spend to provide space. Owning their own servers will be costly to purchase and maintain for Dropbox. They also only hired engineers to their company in the early going to be able to continue to improve the technology they are providing. To keep improving their product they offered beta testers the opportunity to test the product and see how they like it. They also listened to their customers after the launched to see what they liked and did not like. This led them to develop a feature of the product that allows the customer to provide feedback to the company. They also observed users using the product to see if it fit the needs of a  basic user, which turned out to be very beneficial to the company. Dropbox launched their product in 2008. While the product was still in beta it began to gain customers through various websites and technological competitions for startup companies. This allowed Dropbox to get their name out there to the people who most likely are already using similar products or have the need for this product. When they launched the product they used the freemium business model where they offered free use for up to 2G of space and you could pay a premium for more space. They wanted to grow rapidly in the market to gain as big of market share as possible in the shortest amount of time. They also found great success from word of mouth referrals and viral marketing campaigns. Dropbox’s biggest problem they needed to solve early on was their customer acquisition rate. They found that in the early going to cost about 300 dollars per customer they had pay. This was due to the amount of free space given away to the amount that people were paying for. This does not set them up to be successful financially if it didn’t improve. Dropbox was able to figure this out and lower their costs but utilizing more word of mouth referrals. Dropbox was fortunate enough to have backers that supported their company in the early going with enough money to keep the company going until they could gain the following needed to decrease costs. They have a greater opportunity for profit then most of their competitors because of their use of Amazon’s server instead of buying and maintaining their own, especially with the decreasing rate of renting server space.

The Kongo and the Pygmy Tribes in the Modern Day Zaire Essay -- Explor

The Kongo and the Pygmy Tribes in the Modern Day Zaire The study of tribes in the Congo is a very confusing matter. Linguistic, regional and political divisions are all very prevalent characteristics of these people. Two tribes who speak the same unique language may be separated by thousands of miles. The three major linguistic groups are the Bantu, Central Sudanic, and Ubangian with Bantu being the most prevalent. 2000 to 3000 years ago large numbers of Bantu speaking people slowly but steadily began to migrate from modern day Sudan to the Congo basin, or modern day Zaire (www.nbufront.org). The original inhabitants of this area were the Pygmies, the diminutive forest people. I am going to focus on the two most celebrated of the Congo civilizations: the Kongo Kingdom and the Pygmy tribe. The Kingdom of the Kongo began as a small Bantu-speaking chiefdom founded by Ntinu Wene near the modern day town of Boma in the fourteenth century (Ranger pg. 29). The kingdom expanded rapidly through expansion and conquest of other small chiefdoms. Kingship was a pil...

My thoughts and reflections Essay

Sustainability I hadn’t considered the inter-plays that exist between the social, environmental and economic aspects of sustainability, I subscribe to the three pillars of sustainability (figure 1), that is each has an impact but they are independent of each other. Figure 1: Three pillars of sustainability Source: Wallis, A. M., Graymore, M. L. M., & Richards, A. J. (2011) p.596. Class discussions and research enabled me to see the interactions between these pillars and I started to contemplate sustainability more as an interactive process aligned with the three spheres of sustainability (figure 2) which I interpret as being of equal importance and that is you connect them all you will achieve sustainability. Figure 2: Three spheres of sustainability Source: Wallis, A. M., Graymore, M. L. M., & Richards, A. J. (2011) p.596. My ecological footprint gave me personal insights into my impact on the environment. I reflected on what I could do to reduce my footprint; an all-electric house, job with extensive car travel and I am a meat eater. What future was I leaving my children and what could I change? I could reduce my consumption of red meat, saving a planet, however the economic and social impact on our farmers for me outweighs the impact on the planet after all that is their livelihood. I can reduce my energy usage by turning appliances off at home and work and I can use technology for meetings to reduce my travel imprint. I watched a number of documentaries on natural disasters and asked myself why we have done nothing to prevent these and what have we learnt. I reflected  on the impact of the recent drought throughout Victoria. Ballarat almost ran out of potable water, our lake ran dry and tourism was in decline. This environmental event was impacting on our economy and the social impact was and is still being felt today. Human behavior changed, current water demand remains at levels of the 1930’s therefore I’ve concluded that humans need a crisis in order to change behaviour for the good of the environment. But have we really learnt from this, the drought of the 1930’s suggest not, evidence was there that we over used the land having a significant impact socially, economically and environmentally but yet natural disasters droughts still occur due to inadequate consideration of all aspects of sustainability. Worldviews and values A light bulb moment – I hadn’t considered sustainability worldviews. Was I more inclined to lean towards the atomistic (individual-centred) view or the holistic (earth-centred) view? On reflection I think for me it is both, unless you hold strong beliefs one way or the other I believe we hover in between; we all interpret data differently based on our starting assumptions and values and are less likely to change our worldview. In particular I reflected on Indigenous Australians who hold to a traditional value, the land is sacred to them; by holding this view they have a positive impact on the environment; they only take what they need, they give back and believe in the spirit of the land. They didn’t need politicians to develop policies and legislation to make them reduce their carbon emissions or to look after the land. I am faced with the dilemma of how we as a nation can make a difference; it appears that I have more questions than I have answers. Sustainability phases Most organisations are slow adapters to change and usually do so as a result of compliance activities being enforced upon them due to new or reformed legislation, a good example of this is OH&S legislation in Australia. Are we doing enough through education to ensure the next generation of leaders will consider sustainability more than a buzz word? We have created a throwaway  society, landfill is becoming scarce and yet our propensity to have the latest gadget is not decreasing, locally, nationally and internationally we need to look at ways in which we can recycle or reuse the materials on a large scale that has a positive impact on the planet. Another light bulb moment came when we researched companies that we believe are sustainable and consider what phase of sustainability they are in. We looked at Acciona Energy and concluded that they are in sustaining corporation phase as they are paving the way in sustainability. Not all would agree as there are people in Ballarat who are opposed to wind farms and their worldviews are strong in the belief the turbines are more harmful to your health and nothing will persuade them otherwise. This re-emphasises that our assumptions and values in many ways holds much stronger than any evidence that may be presented to us that may refute our views. My journey I have discussed and debated the values I hold and how by changing one small thing we can make a difference to our ecological footprint. If everyone made one small change in their lifestyle it may grow into something that will impact positively on the planet; e.g. Earth hour which started as a national event and is now a global phenomenon. I’ve planted a vegetable garden, my meat consumption has decreased and I actively shop for locally produced vegetables and fruit. I have moved my thinking to that of the ‘bullseye’ model (figure 3) which â€Å"shows that the human system, which is broken up into social and economic systems, must stay within the capacity of the social system to be sustainable.† (Wallis, A. M., Graymore, M. L. M., & Richards, A. J. 2011. p.597) Figure 3: Bullseye model Source: Wallis, A. M., Graymore, M. L. M., & Richards, A. J. (2011) p.598. I have contemplated how we move sustainability from a buzz word without introducing legislation which may not change people’s worldview. I work in the not-for-profit sector we are at the compliance phase of sustainability,  we can move to the efficiency phase by building the capacity of our community leaders; raising their awareness of sustainability, allowing them to experience the impact of their decisions and making a change that positively impacts the environment. I have seen sustainable behavioural change occur; such as water demand, if the reason for change is compelling but we have to recognise that change is a journey and for each of us we have to subscribe to the view that we want to change.

Crime Prevention Through Environmental Design Essay

According to Atlas (2008), Crime Prevention Through Environmental Design (CPTED) is a multidisciplinary approach to prevent criminal behavior through environmental design. In order to achieve deterrence effects of criminal behavior, CPTED strategies have been designed to rely on their ability to influence offender’s decision that precedes criminal acts. Therefore CPTED can be seen as an approach to problem solving that takes into account the environmental conditions and the opportunities they offer for criminal behavior occurrence (Cornish and Clarke 1986). Thereafter, it utilizes those perceived opportunities responsible for causing crimes to control access, provide opportunity to see and to be seen and defines ownership while encouraging territory maintenance (Luedtke et al, 1970). In this context CPTED approach to criminology differs greatly from other policing approaches in the sense that CPTED focuses on design in crime prevention unlike other approaches that employ target hardening. Furthermore, CPTED encourage crime prevention through design and place, while policing values effective response to crime incidences by identification and arresting the offenders (Kruger and Liebermann, 2001). In this regard, crime prevention through environmental design can be considered to be slightly different from traditional policing, but its consistent with problem- oriented policing in four ways: first, touches on the broad scope of problem and not crime only; second, involves systematic analysis of crime factors, events and conditions that fosters crime occurrence; third, leads to design of proactive strategies tailored to problem and the specific geographical locations; fourth, involves all stakeholders and makes them active participants for the program for sake of long–term achievement and improvement (Cornish and Clarke 1986). However, it should be noted that CPTED approach focus on design and not safety, and on productive use not security. Therefore this unique focus makes it people centered as opposed to the view that it is police responsibility. However, the tool of design and techniques fall purview of policing prompting it to be a team effort, and thus police participate in the program but do not necessarily control. Historical evolution since 1970s The origin and formulation leading to emergence of CPTED was initially done by criminologist Jeffery Ray who termed it as defensible space and later on it was improved on by architect Newman Oscar (Jeffery1977; Newman1972). It’s a point of worth to note that both Newman and Jeffery were building on the work of Elizabeth Wood. By 1990s Jeffery and Newman models were expanded to involve a multidisciplinary with Newman`s model limiting itself to the built environment. But by 2004, the adopted CPTED model s were those of Newman and Crowe, since Jeffery model was more of psychology and biology and could not fully support the 2nd generation CPTED (Jeffery1977; Newman1972; Crowe, 2000). Furthermore, in 2005 CPTED has gained internationally recognition and acceptance with dropping off Jeffery `s notion of offender’s internal environment (Jeffery1977 Crowe, 2000). The theoretically foundation evolution of CPTED can be traced back in 1960s when Elizabeth Wood developed guidelines aimed at addressing security issues when she was working with Chicago housing authority (Clarke, 1992). In her guidelines, she emphasized on the design that would lead to supporting natural surveillability, though Elizabeth’s ideas were never implemented, they evolved into simple implementation such as street lights to distinguish between outlaws and thieves from legitimate travelers (Luedtke et al, 1970). Today, evolution of theories and research behind CPTED design are rooted in the environmental criminology theories which explain the relationship between place and crime; and also borrow some ideas from rational theories focusing on situational prevention (Clarke, 1992). Both cluster of theories focus on the crime events and how criminal understand and use environmental to their advantage to commit crimes. This evolution in research and theoretical foundation has played a central role in informing strategic design to employ. Strategies utilized in CPTED Strategies formulation in relation to CPTED approach are rooted in the theoretical foundation and scholarly research conducted by criminologists. Crowe (2000) reports that the central tenet used to arrive at the strategies is the analysis of crime and the environment where it occur using an analytic question â€Å"why here†. Furthermore, such analyses have proved that: crimes are specific and situational; crime distribution correlates to land use and transport network; and offenders are usually optimistic and commits crime in place they know well (Atlas, 2008). Moreover, these analyses reveal that opportunities for crime arise out of daily activities and crime places that are often without observer. In reaction to the analyses, criminologists who are proponents of CPTED designed necessary strategies in line with the findings. These are; Natural surveillance, target hardening, terrestrial reinforcement and natural access control (Newman1972; Crowe, 2000) Territorial reinforcement This is physical design that extends a sphere of influence that enhances users to develop sense of territorial control while potential criminals are discouraged while perceiving these controls (Goldstein, 1990). This is promoted and facilitated by features defining property line such as public and private, signs, pavement designs, or gardens well maintained indicate someone takes care of it. This ensures that only persons that belong to a particular place are their. Target hardening Target hardening strategy in CPTED is usually accomplished by features that prohibit access or entry (Kruger and Liebermann, 2001). These features can include locks, interior door hinges or dead bolt for door, gates units points of entry to certain place, fences, trees line, support of alarm system is also useful and can reinforce the design (Cohen, 1979). Natural surveillance These are programs designed aiming at keeping offenders or intruders observable, this is attained by place design that gives an opportunity to see site perimeter or designs that facilitate to see or/and be seen (Kruger and Liebermann, 2001). It is usually achieved through sufficient lighting that enables to observe activities and individuals, building location and orientation, windows that offer two way views. The design features that facilitate natural surveillance need to be supported by observer or CCTV to maximize its effectiveness (Atlas, 2008). Natural access control This strategy aims at decreasing crime opportunity by employing design that denies access to crime targets while at the same time creating a risk perception in criminals (Goldstein, 1990). The strategy is achieved through street designs like side walks, entrance construction and neighbor’s gates; in order to prohibit entrance to private places that discourages ill motives. However, the essence and usefulness of the strategies used in CPTED is not in their effective design, but rather in their implementation and application to offer desired goal (Cornish and Clarke 1986). It`s indisputable that application of CPTED to community has resulted to impressive results that Atlas (2008) reports that accounts to 40% decline in crimes occurrence and prevalence in areas where it has been implemented, this has been accrued to design that minimizes criminal behaviors while encouraging individuals to keep eye on each other, therefore proper implementation is critical to program success. Application and Implementation of CPTED The problem solving approach that uses CPTED is applied in a series of steps that are designed to respond to: what is the problem? Why here? What can be done to solve it? And how well do we solve the problem? (Kruger and Liebermann, 2001) In order to address and satisfy these hypothetical questions in analyzing a crime scene to inform prevention through CPTED approach, application and implementation is usually done through four phases. These four phases of application as stipulated by Goldstein (1990) are: scanning, analyzing, response and assessment (Table1. Application and implementation phases). These phases of application and implementation stages addresses environmental design issues that are critical to applying CPTED strategies in order to solve security problems. Importantly, various factors ought to be considered when applying the program in relation to specific locations and circumstances. As Atlas (2008) acknowledges, easy said than done also do apply to implementation of CPTED program. Challenges in implementing CPTED Like any other project, implementation is usually engulfed in normal problems that face any change process not mentioning resistance. However, the major problems that can be conceptualized in the implementation process of CPTED program are two. First, time allocation for the program implementation may hamper realization of the project goals (Cohen, 1979; Goldstein, 1990). This is in the sense that sometimes time allocated for the implementation of the program may require additional of a longer duration as a result of complexities arising from project implementation while impacting a larger geographical area with a larger number of stakeholders (Table2. Stakeholders involved in CPTED implementation). Secondly, the cost of implementing CPTED program requires significant capital investment (Cohen, 1979) that is really a barrier. However, the challenges of implementation are inventible, yet they can be solved through efficient and effective leadership, increased participation and involvement, and wider consultation with all stakeholders for any given CPTED program.

Symbolism vs. Truth When society allows the manipulation of a sincerely earnest event, during a time when the people of this country long for relief; my inner being becomes greatly enraged. "Serious people with serious purpose": Kathleen Parker has summed the reaction of our society on 9-11-01 as a whole. Political correctness was nowhere insight when the thousands of people united with tremendous strength, absent of ethnics and colors, to overcome the mortal terror of losing our freedom. Everything has a symbolic meaning in one way or another, but the truth has only one–reality. Symbolizing the memorable photo of three New York City firefighters raising the American flag atop a pile of rubble at Ground Zero into a statue honoring the 343 fellow firefighters this country lost on 9-11 is a true show of Americanism, as long as this statue duplicates the actual photographic event.

Global Impacts Essay Example | Topics and Well Written Essays - 4500 words

Global Impacts - Essay Example Louis Vuitton is a luxury fashion and leather goods company headquartered in Paris and France. (Louis Vuitton) India is fast becoming an international fashion destination, coordinating efforts with international designers so that Indian designers are exposed internationally and foreign designs are exposed in India. (Business Desk, 2009) However, there are a number of internal and external environmental factors with respect to marketing strategies that Louis Vuitton will be required to take into account for the purpose of adapting to and entering the India market. Each of these factors will be examined in this essay. In order to facilitate a smooth transition into the Indian business environment Louis Vuitton will be required to understand the cultural differences. The Hofstede Model of Cultural Dimensions can act as a useful guideline for determining the cultural differences in India and what can be done in the business organization to accommodate those differences. Hofstede identified five cultural dimensions that are relevant for global marketing strategies. The first cultural dimension on Hofstede's cultural dimension scale is Power Distance Index (PDI). PDI draws on the level of equity and inequity among the population in a nation's society. High Power Distance Index will mean that power and wealth is distributed at a high rate of inequality in that society. In this regard citizens are generally denied upward growth. Low Power Distance typically means that the society is driven by equal opportunities ambitions.(Hofstede, 2001) According to Hofstede's Power Distance Index, India ranks 77 which is high. However, it is not that far ahead of France's PDI which is at 68 (Hofstede's Dimension of Culture Scale) The average PDI around the globe is 56. (Hofstede's Dimension of Culture Scale) The difficulty with countries showing high PDI rankings for businesses is that the individual from that culture will typically defer to higher authority for a decision even if they are aware that something is terribly wrong and what measures are required to correct it. The Korean Air crash in Guam is one example of the consequences of a high PDI ranking. In this scenario, the pilot made an error which the co-pilot was aware of, but deferred to the pilot's decision who was his superior.(Gladwell, 2008) For the purposes of internal organization of the business office in India, Indian employees are likely to adhere to the power structure within the organization. Even so, a high PDI is also indicative of fear of and ambivalence toward anything foreign.(Chan and Cheung, 2008) The second of Hofstede's cultural dimension is Individualism (IDV). IDV emphasises the level with which the particular society focuses on either individual or collective relationships and achievements. A country with a high IDV ranking is generally one in which the emphasis is on individuality and individual rights. Persons within in high IDV countries gravitate toward more relaxed relationships. Conversely, low IDV rankings are typically characterised by collectivism and more tightly woven relationships between persons. Low ranking IDV countries typically focus on families and a collective approach toward looking out for the members within in their tightly woven circle.(Hofstede, 2001) India's IDV ranking is 48 and relatively low when compared to France which is at 71.
