philippines essays
philippines essays Per Capita Income: The per capita income of a certain country is the GDP of that country divided by the total population. In the Philippines the per capita income is approximately $700. When compared to the per capita income of the United States, which is about $22,000, it is easy to tell that the economy of the Philippines is very, very poor. % FROM AGRICULTURE: 17.1 (important because you would think that since they mainly produce agricultural products that its percentage would be the highest) % FROM SERVICES: 39.2 (also important because you wouldnt think that this one would be the highest) Exports: Traditionally, the Philippines have been primarily an exporter of raw materials and an importer of manufactured goods. This is the role that many third world countries play in the global economy. Electronic and automotive parts, along with garments are the leading merchandise exports of the country. However, the Philippines also rely heavily on import inputs. The country also exports bananas, coconuts, copper, gold, lumber, pineapples and sugar. Imports: The Philippines mostly imports manufactured goods. Certain items remain subject to import regulations such as narcotic drugs, firearms, ammunition, etc. Their chief imports include chemicals, machinery, and petroleum. Trading Partners: The Philippines, like any other country, cannot produce everything that it needs. Instead, it relies heavily on foreign trade. Specialization in production allows for each nation to produce what it produces best, and to trade for products, which it cannot produce as well. This means that if you are better at one thing and I am better at another, rather than each of us trying to do both, we would each do what we are best at. Then, we would exchange what we had produced and both ...

My Days in Jekyll Essays - Orange County Screenwriters Association
My Days in Jekyll Essays - Orange County Screenwriters Association Professor Frazier English 1101-125 22 October 2015 My Days in Jekyll Every year, I go to Jekyll Island for an engineering trip. The group is called TSA (Technology Student Association). Students in TSA from different schools would compete in all kinds of engineering competitions. The time I went that was the most fun was last year with our new engineering teacher, Mrs. Carter. We would be staying for 3 days and since it was professional, we had to bring business clothes. That morning of the day we would leave, we would come to school and put our suitcases in our teachers room and go to our regular classes. Directly after school, we would come and get our stuff and sit in the lobby of our school until the charter bus came. We were on the bus with about 5 different schools. I knew some of them from previous years and others from different school programs. The ride to Jekyll was about 6 hours so we stopped a couple of times to get food. To get to Jekyll Island, we had to cross over a bridge. The bridge was so beautiful. The ocean was blue, birds were flying over it, and the beach was so pretty. When we finally got there, we had to go to a conference center and take a test to qualify to be an officer over the entire program. Some people took the test seriously, but others including me, didnt. After everyone on our bus was finished, we got dropped off at our ho tels. Some of the schools stayed in the same hotel and others stayed in a hotel further. In one room, it was me, my friend and 2 girls from another high school. After we took our showers, me and my friend walked around in our PJs and talked. We saw students from other schools and ended up talking with them too. We finally got back to our rooms around 1:30 am and went to sleep. The next morning everyone woke up and got dressed around 7 to get breakfast from downstairs. We had to leave the hotel and go to the conference room since majority of us had competitions that whole day. I didnt have a competition but my teacher let me observe some of them. There were a lot of competitions. In one room, robots were racing to stack boxes on top one another. I stayed in that room majority of the day we were there. We ate lunch after everyone finished their competitions and went back to the hotel. Everyone changed into some comfortable clothes because we planned on going out. My friend and I went to a ro om with people from another school. We all decided to stay in the hotel and talked about millions of things until we all passed out. When we woke up in the morning, my friend and I went back to our rooms so we could go back. We would be leaving around 2 that afternoon so when we packed, everyone put their belongings under the bus. Some people still had competitions that morning so I decided to walk around with some other students from another school. We went in stores to buy clothes, we made fun of peoples hairstyles and we stopped inside Five Guys for some food and an ice cream parlor for some delicious ice cream. When it was time to go, we walked back to the conference center where our bus would be waiting on us. By the time we left, everyone had gotten to know each other and was talking up a storm on the bus. My teacher said she enjoyed herself and learned quite a lot. This trip was better than the other ones because I met a lot of new faces. I also got a chance to get a preview of competitions so next year I will know what competition I want to do and how Im going to do it. I really had a lot of fun and wish every year would go like this, even though a few people got in trouble.

Heritage Assessment Assignment Example | Topics and Well Written Essays - 500 words
Heritage Assessment - Assignment Example The music called compas has been passed down to my children. They know many of the lyrics to the music I listen to. I have also maintained the Haitian language. It is French Creole. As a result I speak French, Spanish, Creole, and English. The religion practiced in Haiti and here for my family is Baptist. Religion is very important to me. Although I live in the United States, I have not forgotten where I have come from. My religion, food, family, and culture are deeply rooted in Haiti. Although my family came to the United States for greater opportunities, this never impacted my feelings about my culture. I am Haitian. My traditions and beliefs have remained strongly rooted in my birthplace. My large family is unique in American culture. Coming from a large family has helped me understand sacrifice, love, and tradition. I will admit that I have become Americanized to a degree, but I will always be Haitian. That is the good thing about America. I can live here, but still retain my own culture. My ethnic, cultural, and religious heritage will be useful to my healthcare related career in many ways. The first way my ethnic, cultural, and religious heritage will be useful is by knowing the Haitian people. For example, many Haitian children are not vaccinated. When I encounter a parent or child from Haiti that would be one of the first questions I ask. Another question would be if the patient from Haiti had a TB test. Haiti has a higher rate of TB than other countries. Other healthcare providers might not know these facts. Informing my colleges and fellow Haitians would help patients better understand each other. Sometimes Haitians that have newly arrived do not trust the government, medical staff, or others due to immigration status. If it is revealed that the child or adult does not have immunizations or a TB scan, the patient might feel that INES might be called. This can be very dangerous to the patient and everybody in contact with the patient. I would be

How to get rid of your babysitter Essay Example | Topics and Well Written Essays - 500 words
How to get rid of your babysitter - Essay Example Most parents are usually at the dilemma on how to handle situations in which they need to send away their babysitter as they may not know how to go about it without hurting their feelings. Getting rid of the babysitter should be conducted in a manner that the babysitter will not feel offended or they are being sent away without any proper reason. This is because babysitters play very vital roles in the homes and parents with small children cannot do without them hence the need to take proper care of them. The decision to get rid of you babysitter may be motivated by a number of reasons. Such include those failing to perform their duties as already instructed, mismanagement of resources in the house, being extremely demanding by asking for more pay, mistreating the children, lack of professionalism in their conduct, being rude and lacking courtesy among other reasons. In order to get rid of your babysitter, you need to come up with proper and convincing reason for wanting to send them away. Take time to observe their conduct in the house so as to establish if the mistakes being committed by the babysitters are deliberate or they are beyond their control. Upon establishing that the mistakes are repetitive in nature and are due to negligence, record the number of times in which they have been done. The next step is to boldly communicate the reasons to them so that they will also see their mistakes. If the babysitter is from an official agency service, you need to communicate the same information to the agency so that they can be in agreement with the termination of the contract. The final step is to agree with the babysitter on the time of their departure as well as the things that they may need before they depart. These include provision of all the things owed to them as well as some of the things that they may request to go with before they go. Then the babysitter is escorted to the place where she was found so that

Natural environment Essay Example for Free
Natural environment Essay History depicts that in the past, apartheid and Christian national education policies meant that races and cultures were segregated in schools and resources were unevenly distributed, making the role and the task of the teacher extra difficult in terms of balancing between the workload and catering for all learners needs. Education is inherently political as it involves values and goals in relation to such fundamental questions as what kind of individual and society are we trying to shape? These questions cannot be answered in a factual or technical way because they are questions of opinions, values and ideology and they are inevitably disagreements and conflicts (Carter, Harber Serfi, 2003). The nature and reality of educators is that, it places so much importance on the teacher to ensure that learners succeed at the end of the day, although there are some factors external such as the environment, socio-economic and resources issues and resources which disturbs or defeats the purpose of education. The teacher can either make or break the progress of the learner, meaning the teacher should cater equally for all the needs of the learners, as learners themselves are different in terms of race, gender and class. This means that the teacher should not be bias or discriminate towards a certain gender, race or class, as this will have a negative impact on the success or progress of the learners. In this essay I will discuss my experiences with the teachers who made a difference, the role they played in terms of perceiving gender, race and class in my life, and the reasons why they were significant and finally I will discuss the role I will play as a future teacher regardless of gender, race and class of the learners. The most features in class or school environment, is for the teacher to understand his or her learners and mostly interact with them on continuous basis, as problems learners encounter arise from time to time. These problems tend to distract learners and need the intervention of the teacher themselves. Sometimes learners struggle with the content required, a problem at home or moreover a personal problem. A good teacher must anticipate and have insight of foretelling and differenti ate amongst learners that are showing signs of encountering problem

Neural Cells as Harmony Detectors :: Neurology Brain Essays
Neural Cells as Harmony Detectors The issues of harmony have notably low profile in the current AI research. Meanwhile, when it comes to brain architecture, harmony plays the central role. As we hope to demonstrate in this essay, neural cells act primarily as local harmony detectors. On a less local scale, the consensus is that perceptions correspond to certain stable periodic patterns of neuron firing. A harmony-based architecture would probably be more successful than current AI paradigms. It would help here to recall the basics of neuron firing theory. In the rest state neuron membrane typically has electrochemical polarization potential of 70 millivolts. When the firing impulse comes to the neuron from another neuron via the corresponding synapse (the site of their connection), this polarization potential changes, typically by 1-2 millivolts or less. If the polarization potential decreases beyond the threshold of approximately 60 or 55 millivolts, the neuron fires, otherwise the polarization potential tends to rapidly relax to the original rest level of 70 millivolts. Hence, when the reception of an impulse via a synapse decreases the membrane polarization potential of the receiving neuron, we call this synaptic connection excitatory, because the decrease of the polarization potential makes it easier to fire for our neuron. Otherwise, the synaptic connection is called inhibitory. Because the reception of an impulse changes the polarization potential by at most 2 millivolts and because the polarization potential tends to rapidly relax back to 70 millivolts, the neuron can fire only if it receives several (from 4 to more than a dozen) impulses via excitatory connections simultaneously or in a very quick succession. Hence the neuron works as a detector of several excitatory impulses coming almost simultaneously. So we can say that the neuron detects the harmony between its incoming impulses. Now we shall turn to learning mechanisms in the brain, and observe that the local learning (on the level of one neuron) is directed towards detecting this harmony even better. As we have noted, the reception of an impulse changes the polarization potential usually by 2 millivolts or less. The actual value of this change is usually called synaptic strength. This value is not constant, but changes with time. This ability of synaptic strength to change is the key mechanism of neural learning and is called synaptic plasticity. The most typical rule of synaptic plasticity for excitatory connection works approximately as follows. If a neuron fires shortly after receiving an excitatory impulse (i.

Radio and European History Essay
Radio broadcasting has been viewed by governmental agencies across the globe as a contributing medium that served its growing audience. Across the years, radio broadcasting has provided entertainment and information to a diverse audience from local to, regional and international reach in commercial, social or political atmospheres. Radio broadcasting, according to Godfrey (2006), is a primary source material and an information tool as it directly observes and relates relevant events. Along with photographic records, physical remains and oral sources, radio and television broadcasts are potent sources of unfiltered evidence closer to an event, as Godfrey added. The acquisition of specific details that try to retain the images of an event through an actual experience has led Puddington (2003) to believe that media has challenged the shape of history. The significant claims on the importance of radio broadcasting drives home the idea that its classification as a primary source of data may is its contribution to history. More importantly, this paper shall strive to prove how radio broadcasting shaped European History as it gears up a strong hypothetical contention that radio broadcasting had a definite role in the shaping of European integration. The age of airwaves begun after the series of discoveries that led to the invention of the wireless telegraph. It soon signaled the birth of the radio telegraph that allowed a wide range of sounds, music and human voice to be transmitted in a new technology in 1914 according to Godfrey. Historically, it was also a crucial time fraught with misunderstanding and strife that divided Europe into armed camps. World War I broke out with Germany leading the war for control in Europe. History would recall that as early as 1872, Germany had entertained plans to control the European region as it dominated European diplomacy while France remained isolated from the rest according to Viault(1990). An ongoing international crisis had threatened to move the European powers closer to the brink of war by the 1900ââ¬â¢s. Still in the throes of hectic plans and preparation, Germany had to content itself with waiting for a few more years before striking a match to light the flames of war. Earlier on, Europe was in its creative prime as artistic activities catered to a romantic era of the 1800 and onwards, a little over a century before radio ruled technology. It was also a century of inventions and research that became a turning point for technology to prosper. Europe while in an age of development was politically stocked under a conservative rule which soon gave way to a movement effectively fighting for reform. While Britainââ¬â¢s royal and upper classes rejected political democracy, France also became very authoritarian that soon culminated in the 1848 revolution which Viault (1990) related. A growing powerful ideology of nationalism also promoted a disintegration of the Austrian empire in Central Europe that soon resulted to a few alliances among nations while contributing to reckless disintegration across the regions of Europe. In effect, Europe was in mindless turmoil and at a crossroads during a century rich with creative thought yet devoid of an amplified objective. At the onset of World War I, wireless transmission proved to be an invaluable tool to the military although they were quite wary of its potential use in espionage and mass propaganda. Indeed this was the actual case as Ireland and Britain were able to recruit young draftees for World War I following the RMS Lusitaniaââ¬â¢s bombing off the coast of Ireland on the way to Lverpool by a German U-boat (Readerââ¬â¢s Digest, 2003). As the United States courted the use of radio for home entertainment, BBC (British Broadcasting Corporation) used the radio for news and entertainment with immediate plans to isolate it from political pressures as it battles with pay for radio entertainers as reported by the NY Times (Jun, 28, 1925). Radio broadcasting was also seen among countries in Europe as serving well in fostering good-will and amity among the nations of Europe and paving the way for unity as reported again in the NY Times (Jun 7, 1931). Such movement was instrumental in the recruitment of soldiers to serve in the allied force against Nazi Germany. In a specter of a growing 2nd World War brought about by rising Nazi Germanyââ¬â¢s plan for domination, the radio technology was already seen as a tool in war efforts. At the outbreak of World War II, radio broadcasting reached the height of international worth as it carried news from the battlefront into the homes of listeners worldwide. Radio Commentator Edward Murrow had created sensations with eyewitness description of London during German bombing raids according to Godfrey (2006). Murrow had also reported on the Buchenwald Concentration Camps on April 11, 1945 according to Puddington (2003) which was instrumental in calling an end to the genocide. War was soon declared over the airwaves as Adolf Hitler set his conditions for war and genocide in Europe over Radio Hamburg in Viault (1990). The radioââ¬â¢s instrumental contribution to defeat the enemy camp of Hitler was made clear as allied camps tried to disrupt German military communications signals. Germany retaliated by jamming the signals and broadcast yet heavily lost amidst allied Europeââ¬â¢s hands. After the war, efforts to curb Russian communism was in the mainframe of Europeââ¬â¢s Radio Liberation programs that prayed for a Stalin and communist era to end. In the dark days of anti-Stalin struggle, the radio broadcast was again used as a weapon of psychological warfare according to Puddington (2003). Under a movement to free Europe from any communist rule after defeating Nazism, the Cold War between the US and USSR became a regional problem in Europe. Radio Free Europe (RFE) was established as a secretly American-funded station whose main objective was to spread the evils of communism. The Russians however werenââ¬â¢t quick to believe any evil broadcasts against their leader who defeated the evil Hitler and the Nazis as Puddington reasoned. By the 1970ââ¬â¢s, Radio Liberty in Europe had ranked as the most influential international broadcast station with an impressive staff of exile writers and a growing Soviet audience in Puddington (2003). Stalinââ¬â¢s death in 1953 created a widening room for anti-communism ideas that had sacrificed the radio station and many of its staff and workers in the interest of international peace and harmony. Poland had once pleaded to abolish Radio Liberty and Radio Free Europe in order to maintain diplomatic ties with Russia but other European countries opted for the propaganda movement against communism to remain heard. Shortwave broadcasts around the Czech Republic continued despite jamming from the Soviet communist regime. Likewise in West Germany, the country researched and studied the Soviet system of governance dedicated to the cause of freeing East Germany. Radio stations were tapped all around Europe as visible stars in an anti-communist sentiment. In a landscape of remembrance for the human efforts to attain peace and freedom, the advent of radio has ultimately provided an integral element in the unity and integration of Europe. Through radio broadcasting, information was disseminated across a wider population that became instrumental in creating an alliance among nations who desired for peace and freedom rather than dominion. The historical separation of European countries in the 19th century prior to the advent of radio technology was soon disbanded in an effort to create an alliance of nations. The Universal Declaration of Human Rights spoke of the right to receive and impart ideas and information regardless of frontiers. Radio broadcasting as the prevalent technology in an era fraught with wars and conflicts became a tool that united European nations to unite for a common cause of peace and freedom. Radio Broadcasting has therefore shaped the modern worldââ¬â¢s history as a modern global tool that permitted countries to unite under a common goal for peace.

Muslim Cities DBQ Essay
The Post-Classical Era was a time of goodness in the Middle East. Goods were plentiful, Islam was spreading, and the people were wealthy. The Muslim cities spread innovations throughout the world. The document groupings for the discussion of this topic are as follows: Documents 2, 1, and 5 are for city significance. Documents 3, 5, and 8 are for importance of trade. Finally, documents 4, 6, and 9 are for government and its role. Document 7 has been omitted due to the fact that it does not support my thesis. Muslim cities were abundant with knowledge, which they spread throughout the world. Scholars of all religions studied in Muslim cities, which were some of the first cities to produce books. In Document 2, a Muslim historian describes Cordoba, stating: ââ¬Å"Unto it flocked seekers of science and poetry, for it was a resort of the noble and a mine of the learned.â⬠It was a center of knowledge-seekers, perfect for any type of learned person. As the scholars came and went, they spread their knowledge with them, eventually spreading it all over the world. In addition to having much knowledge, Muslim cities also accumulated much wealth. Document 1 describes Damascus as ââ¬Å"the paradise of the eastâ⬠, discussing its luxurious features. Document 5 discusses the highly-priced silks that were sold in Muslim cities. I request an additional document, in which a non-Muslim describes Muslim cities, to better understand an outsiderââ¬â¢s point of view. Trade was a large part of both Muslim and Arabic culture. It was how ideas and innovations spread all over the world; simply through word of mouth. Document 3 mentions Cairoââ¬â¢s numerous shops in the 11th century, of which the Sultan owned. Cairo was a rich city, of which was popular for trade. Document 5 describes trade in Tabriz, and the expensive materials that were traded. Document 8 is a map that shows numerous Muslim trade routes across North Africa, Southern Europe, and several parts of Asia. Muslim traded in many parts of the Eastern world, travelling by both land and sea. I request a trade catalog, to better prove where Muslims may have traded in the Post-Classical Era. Muslims were not always secure in government. In Document 4, Caliph Abd al-Malik forbade Syrian Muslims from making annual pilgrimage to holy citiesà (some of which are mentioned in Document 9) due to the fact that they had a high chance of being attacked. The Muslim people were upset, but they were unable to convince their leader to change his mind. In Document 6, walls were built to guard Muslims from attackers (which was not always successful; as the Mongols and the Crusades had been successful attackers). In conclusion, The Muslim cities spread innovations throughout the world. Their populated and learned cities were a gateway to trade, which lead to successful trading all over the world. They shared their ideas with many nations, despite the fact that they occasionally had a weak government.

Parkinsons Disease essays
Parkinsons Disease essays Parkinsons disease usually affects people of late middle age. Most run between the age of 50-60. The symptoms of Parkinsons disease are usually subtle and occur gradually. Some examples of symptoms a person may have, are feeling shaky or having trouble getting up from a chair or a couch. Others may notice that their speaking is softer or quieter. They will lose track of a thought or feel irritable or even depressed for no reason. These are early symptoms that may last a long time before the more classic and obvious symptoms appear. For now there is no way to cure or prevent Parkinsons disease from happening., but there has been new research looking at (PET) Position Emission Topography. This will allow scientists to scan the brain, which see chemical change that occurs in the brain. Using PET scientists can study the brains nerve cells that are affected by disease. IF you are in the major stages of Parkinsons disease the major symptoms are tremors, problems walking, bradykinesia, and rigidity. Rigidity is an increase of stiffness in the muscles. If it is eased by medications, rigidity is always present. Its also responsible for a mask like expression. In some patients it leads to sensations of pain in the arms and shoulders. Secondly, victims with experience bradykinesia, which means slowness of movement. It causes the brains to react slower in its transmission of instructions to parts of the body therefore causing the body to act slowly in carrying them out. Poor balance is often true when victims move abruptly. Some patients experience falls due to poor balance. Last are tremors, they will affect three out of four patients. Tremors may affect only one part or side of the body. For the most part they dont disable people and it disappears during sleep. Some minor symptoms are depression, emotional changes, me ...

Trash Islands - the Ocean Garbage Patch
Trash Islands - the Ocean Garbage Patch As our global population expands, so does the amount of trash we produce, and a large portion of that trash then ends up in the worlds oceans. Due to oceanic currents, much of the trash is carried to areas where the currents meet. These collections of trash have recently been referred to as marine trash islands. The Great Pacific Garbage Patch The Great Pacific Garbage Patchsometimes called the Eastern Garbage Patchis an area with an intense concentration of marine trash located between Hawaii and California. The exact size of the patch is unknown, however, because it is constantly growing. The patch developed in this area because of the North Pacific Subtropical Gyre- one of many oceanic gyres caused by a convergence of ocean currents and wind. As the currents meet, the earthââ¬â¢s Coriolis Effect (the deflection of moving objects caused by the Earthââ¬â¢s rotation) causes the water to slowly rotate, creating a funnel for anything in the water. Because this is a subtropical gyre in the northern hemisphere it rotates clockwise. Itââ¬â¢s also a high-pressure zone with hot equatorial air and comprises much of the area known as the horse latitudes. Due to the tendency of items to collect in oceanic gyres, the existence of a garbage patch was predicted in 1988 by the National Oceanic and Atmospheric Association (NOAA) after years of monitoring the amount of trash being dumped into the worlds oceans. The patch was not officially discovered until 1997, though, because of its remote location and harsh conditions for navigation. That year, Captain Charles Moore passed through the area after competing in a sailing race and discovered debris floating over the entire area he was crossing. Atlantic and Other Oceanic Trash Islands Though the Great Pacific Garbage Patch is the most widely publicized of the so-called trash islands, the Atlantic Ocean has one as well in the Sargasso Sea. The Sargasso Sea is located in the North Atlantic Ocean between 70 and 40 degrees west longitude and 25 and 35 degrees north latitude. It is bounded by the Gulf Stream, the North Atlantic Current, the Canary Current, and the North Atlantic Equatorial current. Like the currents carrying trash into the Great Pacific Garbage Patch, these four currents carry a portion of the worlds trash to the middle of the Sargasso Sea where it becomes trapped. In addition to the Great Pacific Garbage Patch and the Sargasso Sea, there are five other major tropical oceanic gyres in the worldall with conditions similar to those found in these first two. Components of Trash Islands After studying the trash found in the Great Pacific Garbage Patch, Moore learned that 90% of the trash found there was plastic. His research groupas well as NOAAhas studied the Sargasso Sea and other patches around the world and their studies in those locations have had the same findings. It is estimated that 80% of the plastic in the ocean comes from land sources while 20% comes from ships at sea. The plastics in the patches consist of items like water bottles, cups, bottle caps, plastic bags, and fish netting. Itââ¬â¢s not justà large plastic items that make up the trash islands, however. In his studies, Moore found that the majority of the plastic in the worlds oceans is made up of billions of pounds of raw plastic pellets called nurdles. These pellets are a byproduct of plastics manufacturing. It is significant that most of the trash is plastic because it does not break down easilyespecially in water. When plastic is on land, it is more easily heated and breaks down faster. In the ocean, the plastic is cooled by the water and becomes coated with algae which shield it from sunlight. Because of these factors, the plastic in the worldââ¬â¢s oceans will last well into the future. Garbage Islands Impacts on Wildlife The presence of the plastic in these patches is having a significant impact on wildlife in a number of ways. Whales, seabirds, and other animals can easily be snared in the nylonà nets and six-pack rings prevalent in the garbage patches. They are also in danger of choking on things like balloons, straws, and sandwich wrap. Additionally, fish, seabirds, jellyfish, and oceanic filter feeders easily mistake brightly colored plastic pellets for fish eggs and krill. Research has shown that over time, the plastic pellets can concentrate toxins which are passed on to sea animals when they eat them. This could poison them or cause genetic problems. Once the toxins are concentrated in the tissue of one animal, they can magnify across the food chain similar to the pesticide DDT. Finally, the floating trash can also aid in the spread of species to new habitats. Take, for instance, a type of barnacle. It can attach to a floating plastic bottle, grow, and move to an area where it is not naturally found. The arrival of the new barnacle could then possibly cause problems for the areas native species. The Future for the Trash Islands Research conducted by Moore, NOAA, and other agencies show thatà trash islands are continuing to grow. Attempts have been made to clean them up but there is simply too much material over too large of an area to make any significant impact. Some of the best ways to aid in the cleanup of these islands are to suppress their growth by enacting stronger recycling and disposal policies, cleaning up the worlds beaches, and reducing the amount of trash going into the worlds oceans.

Remote Access Attacks Case Study Example | Topics and Well Written Essays - 1250 words
Remote Access Attacks - Case Study Example The other assumption would be the network was setup by a rookie as the topology is poor and vulnerable to attacks. Finally the final assumption would be the management is not aware of the need of a secure network. The management needs to be informed and enlightened on information confidentiality, integrity and availability (Lammle, 2008). Firstly the network is vulnerable as the firewall doesnââ¬â¢t serve its purpose. Firewall is meant to barricade the traffic between a public and private network. In our case the public network is the internet and the private network is the Quick Finance Network. It uses access lists and other methods to ensure the security of the private network. From the diagram the firewalls should be deployed between the router and the internet, and the web server and the internet and between the internet and the VPN server. Access lists that are employed on the firewall are set of conditions kept by routers that determines allowed traffic to and from various services on the network. In the quick finance network access lists can be deployed in the network to control the movement of traffic between the different buildings and also in a building, in case of information applying to specific offices/departments. Access lists are helpful in exercising control over network traffic. Access lists offer network control. These lists enhance the flexibility to filter the packets that flow in or out router interfaces. The access lists help protect expanding network resources without impeding the flow of legitimate communication. They differentiate packet traffic into categories that permit or deny other features. Proxy is another security measure that can be deployed. Proxy restricts who accesses what and which sites to block. The layer design deployed also needs to be improved. The network needs to be created using the proposed three layer design. The proposed three layer design comprises of core layer- this is where the public and private networks meet through a firewall router/switch, distribution layer ââ¬â this layer holds switches which lead to different buildings and offices and access layer ââ¬â the layer where the user is connected to the network. Vulnerabilities on this network There lots of vulnerabilities on this network and lots of access points where intruders can gain entry of this network. For starters the firewall has been wrongly placed. The firewall should be put across the perimeter of the network in order to limit access to the network. From the topology the firewalls donââ¬â¢t serve their purpose as they have been put beside the servers. The firewall is used for basic packet filtering. The filtering decision is made separately for every packet, thus a packet that was allowed earlier wonââ¬â¢t dictate the entry of a later packet. Itââ¬â¢s based on source and destination IP address, protocol and source and destination port numbers. The network should use the proposed layer 3 network model. Where we have three layers: access layer, distribution layer and core layer. This will avoid a bad topology as the current one where all the machines are connected via an Ethernet cable. With a layer three topology it would implement use of switches and more routers to control movement of packets and enforce access control. It would also have all the servers well placed in order to ensure data security, availability, integrity and confidentiality

Assessment, Management and Reduction of Falls in the Older person Essay
Assessment, Management and Reduction of Falls in the Older person - Essay Example This concept indicates a factual phenomenon that the life span of people aged 60 and above has steadily increased in the past half century. There are over 600 million in 2000; 1.2 billion in 2025 and 2 billion in 2050 (WHO). This phenomenon has created a huge sector in the society, which is comprised by people from age 60 and above. The occurrence of this size of a population of people who are 60 and above is unheard of, throughout recorded history because certain conditions meant that people normally and generally lived only until an average of thirty-five. However, with the advancement of medical technology the increasing number of people who survive to above 60 years old is a commonality (WHO 1999).
