If so, is routed between the networks, otherwise it stops. A firewall filters incoming and outgoing traffic. You can also manage public access to private networked resources such as host applications. It can be used to record all attempts to enter the private network and trigger alarms when hostile or unauthorized entry attempt. Firewalls can filter packets based on their source and destination addresses and port numbers. This is known as address filtering. Firewalls can also filter specific types of network traffic. This is also known as protocol filtering because the decision to forward or reject traffic depends on the protocol used, such as HTTP, FTP or Telnet. Firewalls can also filter traffic by packet attribute or state. A firewall cannot prevent individual users with modems to dial in or outside the network without going through the firewall at all. Employee misconduct or negligence cannot be controlled by firewalls. Policies regarding use and misuse of passwords and user accounts must be strictly enforced. These are management issues that must be asked in the planning of any security policy, but cannot be solved with firewalls alone. [5] 2.1Advantages of Firewalls Firewalls have a number of advantages. They can stop incoming requests for services, fundamentally insecure, as may be prohibited or rlogin RPC services such as NFS. They can control access to other services such as bars appellants from certain IP addresses, use the filtering service (incoming and outgoing), for example, to stop hiding information about FTP, in writing, for example, allowing access only to certain directories or systems Are more profitable than ensuring every guest on the corporate network, as it is often only one or a few systems firewall concentrate. They are safer for every guest, because of the complexity of the software on the machine which makes it easier for security holes appear. 2.2 Disadvantages of Firewalls Firewalls are not the alpha and omega of network security. They have some disadvantages, such as: It is a focal point for attack, and if a hacker penetrates the firewall that can have unlimited access to the corporate network. You can prevent legitimate users access to services of value, for example, business users will not be released to the web or when working outside the home to a business user can not access the organization track network. No protection against attacks from the back door, in May and encourage users enter and exit through the door, especially if the restrictions are too severe service. Examples of entry points to the back door of the network business are: modems, and import and export unit. The security policy should cover such aspects as well. They can be a bottleneck for the flow, since all connections must pass through the firewall system. Firewall systems themselves can not protect the network against smuggling of import or export of material to prohibit such game programs firewalls as attachments to email messages. Smuggling could also be an important source of infection if users download software from external newsletters recent Melissa virus and the Love Bug have been smuggled into the e-mails to unknown recipients. This is an area that security policy must be addressed. There are software programs that can help in this instance MIMEsweeper runs on the firewall and monitoring of e-mail attachments before you let them pass. It will remove potentially dangerous attachments or prevent the mail from all over. The main disadvantage of a firewall is that it protects against the aggressor inside. Like most computer crimes are perpetrated by corporate internal users, a firewall offers little protection against this threat. For example, an employee may not be able to email sensitive data on the site, but may be able to copy on a floppy and after it. Therefore, organizations need to balance the amount of time and money they spend on the firewall with one on other aspects of information security. [3] Firewall function III There are two methods of denial of access used by firewalls. A firewall may allow all traffic through unless it meets certain criteria, or you can deny all traffic unless it meets certain criteria (see Figure 3.1). The type of criteria used to determine whether to allow traffic through varies from one type of firewall to another. Firewalls may be concerned about the type of traffic, or source or destination addresses and ports. They can also use complex rule bases that analyze the application data to determine whether traffic should be allowed to pass. How a firewall determines what traffic to pass depends on the network layer it operates.[5] Figure 3.1: Basic Firewall Operation Firewall Types IV A real firewall is hardware and software that intercepts data between the Internet and your computer. All data traffic must pass through it, and the firewall allows the data is allowed through the corporate network. Firewalls are typically implemented using one of four major architectures: â‚ ¬Ã‚  Packet Filters â‚ ¬Ã‚  Application Gateways â‚ ¬Ã‚  Circuit -level Gateways â‚ ¬Ã‚  State -full inspection 3.1 Packet Filters The first line of defence in protecting firewalls and most fundamental is the packet filtering firewall. Packet filters operate at the network layer to examine incoming and outgoing packets and applying a fixed set of rules for determining whether packets are allowed to pass. The firewall packet filtering is generally very fast because it does not take into account some of these data in the packet. Just analyze the header of IP packet, IP addresses, source and destination, and combinations of ports and then applies filtering rules. For example, it is easy to filter all packets destined to port 80, which could be wearing a Web server. The administrator can decide which port 80 is off limits except to certain IP subnets, and a packet filter would suffice. Packet filtering is fast, flexible, transparent (no changes required on the client) and inexpensive. Most routers offer capacities of packet filtering and pure firewall packet filter does not require powerful hardware. This type of filter is commonly used in businesses small and medium enterprises that need to control users can or can not go. IP addresses can be distorted by this type of filter media itself is not sufficient to stop an intruder from accessing your network. However, a packet filter is an important component of a server solution for complete security. [4 vara] Fig 4.1 packet filtering[4] 3.2 Circuit-level Gateways A step above the standard packet filtering firewall, but still considered part of the same architecture, are the gates of the circuit, also known as Stateful Packet Inspection. In the circuit level firewall, all connections are monitored and connections that are deemed valid are allowed to cross the firewall. This usually means that the client behind the firewall can initiate any type of session, but customers outside the firewall can not see or connect to a machine protected by the firewall. State inspections usually occur in the network layer, which makes it fast and preventing suspect packets travel up the protocol stack. Unlike static packet filtering, however, an inspection of State takes decisions on the basis of all data in the packet (which corresponds to all levels of the OSI model). Using this information, the firewall builds dynamic state tables. Use these tables to keep track of connections through the firewall instead of allowing all packets meeting the requirements of all rules to adopt, allows only the packets that are part of a valid connection, prepared social. The firewall packet filtering is popular because they tend to be cheaper, faster and relatively easy to configure and maintain. [4vara] Fig. 7.2: Circuit Proxy 3.3 Application Proxies Working in the implementation of the OSI model, proxy firewall forces all client applications on workstations protected by the firewall to use the firewall as a gateway. The firewall allows each package for each different protocol. There are some drawbacks to using this type of firewall. Each client program must be configured to use a proxy, and not everyone can. In addition, the firewall must have a representative in the same for each type of protocol that can be used. This May, a delay in the implementation of new protocols, if the firewall does not. The penalty paid for this extra level of security is the performance and flexibility. Firewall proxy server processor and large memory to support many simultaneous users, and the introduction of new Internet applications and protocols can often involve long delays, while developing new powers to support them. True proxies are probably the safest, but to impose a surcharge on the network load. Dynamic packet filtering is definitely faster, but the highest end firewall these days are hybrids, incorporating elements of all architectures. [4vara] Fig. 7.3: Application Proxy 3.4 Stateful Inspection The optimal firewall is one that provides the best security with the fastest performance. A technique called Stateful Multi-Layer Inspection (SMLI) was invented to make security tighter while making it easier and less expensive to use, without slowing down performance. SMLI is the foundation of a new generation of firewall products that can be applied across different kinds of protocol boundaries, with an abundance of easy-to-use features and advanced functions. SMLI is similar to an application proxy in the sense that all levels of the OSI model are examined.Instead of using a proxy, which reads and processes each packet through some data manipulation logic, SMLI use traffic-screening algorithms optimized for high-throughput data parsing. With SMLI, each packet is examined and compared against known state (i.e., bit patterns) of friendly packets one of the advantages to SMLI is that the firewall closes all TCP ports and then dynamically opens ports when connections require them. This feature allows management of services that use port numbers greater than 1,023, such as PPTP, which can require added configuration changes in other types of firewalls. Statefu inspection firewalls also provide features such as TCP sequence-number randomization and UDP filtering.

Hardware firewalls can be effective with little or no configuration, and can protect every machine on a LAN. Most hardware firewalls will have a minimum of four network ports to connect other computers, but for large networks, firewall solutions for enterprise networks are available. A hardware firewall uses packet filtering to examine the packet header to determine their origin and destination. This information is compared to a set of predefined rules or created by the user determine if the packet is sent or deleted.[2] As with any electronic equipment, a user with general computer skills can connect a firewall, adjust a few settings that work. To ensure that the firewall is configured for optimal security and protection, however, consumers certainly have to learn the features of your hardware firewall, to enable them, and how to test your firewall to secure your done a good job of protecting your network. Firewalls are not all equal, and it is important to read the manual and the documentation that came with the product. In addition the manufacturers site will generally have a database or FAQ to get you started. If the terminology is a bit too tech-oriented, you can use my library technical terms to help you get a better understanding of certain terms of technology and equipment is where you configure your hardware firewall. To test the security of your hardware firewall, you can buy third party software or a review of research on the Internet for a free online service that is based on testing of firewalls. Test firewall is an important element of maintenance to ensure that your system is configured for optimal protection provided.[2vara] Figure-1 Hardware Firewall Hardware firewall providing protection to a Local Network [3vara] 2.2 Software Firewalls For users of the detached house, choosing the most popular firewall is firewall software. Firewall software installed on your computer (like any software) and can be customized, allowing some control over its function and protection features. A firewall software to protect your computer from outside attempts to control or access your computer, and your choice of firewall software, you can provide protection against Trojans, the most common or e-mail to. Many software firewalls that the user defined controls for setting up files and share printers and block harmful applications from running on your system. In addition, the firewall software may also include access control, Web filtering and more. The disadvantage of software firewall is that it protects only the computer that are installed, no network, so that each team must have a software firewall is installed. [2] As hardware firewalls are a large number of firewalls to choose from. To begin, we recommend you read the comments of firewall software and search the product website to get some initial information. Because your firewall is always running on your computer, you must take note of system resources will be required to execute and possible incompatibilities with your operating system. A good software firewall will run in the background on your system and use only a small amount of system resources. It is important to monitor firewall software, once installed and to download updates provided by the developer. The differences between software and hardware firewall are enormous and the best protection for your computer and the network is to use both because each offers different, but very necessary for safety and performance. Update your firewall and your operating system is essential to maintain optimal protection because it is proof of your firewall to ensure it is connected and working properly. [2 vara] Figure-2 Computer with Firewall Software Computer running firewall software to provide protection [3 vara] Table 5.1: firewall comparison Advantages Disadvantages Hardware Firewall Operating system independent Not vulnerable to malicious attacks Better performance Focuses on only firewall-related duties Can be single point of failure Higher administrative overhead Higher cost to implement and maintain Software Firewall Less expensive to implement and maintain Lower administrative overhead Dependent upon host operating system Requires additional host hardware, Vulnerable to malicious attacks, Lower performance [6]

Nervous System :: essays research papers

Nervous System The two types of the nervous system are the Central nervous system and the peripheral nervous system. They are responsible for integrating, processing, and coordinating Sensory data and motor commands the central nervous system, which interprets sensory input and carry information to maintain homeostasis. CNS canà ¢Ã¢â€š ¬Ã¢â€ž ¢t be regenerate because a CNS consists of the spinal cord that mean if ità ¢Ã¢â€š ¬Ã¢â€ž ¢s break the spinal cord is break also. The peripheral nervous system consists of the nerves that branch from the brain and spinal cord. It is a thick bundle of nerve fibers located within the spinal cord. The PNS can be regenerate and it will regrow. The brain and spinal cord are the main parts of the nervous system. The brain controls every part of your body and is located top of our head inside our skull. The spinal cord with controls our movement. Nerve cells contain 3 parts: dendrites, cell body and the axon. Dendrite is the receiving part of the neuron. It is a short extension of the cell body And send signals toward the cell body and the cell body conducts nerve impulses which in the transmission of the nerve impulses from the region to the other cell. The axon is a single extension carries the message to the next neuron, which controls all of the nerves. The nerve impulse is response of the neuron. There are 3 classes of neurons: sensory neurons, motor neurons, and interneurons. Neurons are also called nerve cells. A sensory neuron takes information from a receptor to the CNS. A motor neuron takes information away from the CNS. An interneuron transfer information between neurons in the CNS. It also sending out signal to the muscles resulting in contraction or movement. Nerves impulse occurs when an action potential changes rapidly. When action potential occurs, the sodium gates will open as Na+ flowing into the axon the changes from à ¢Ã¢â€š ¬Ã¢â‚¬Å"65mV to +40mV, this is call depolarization and during repolarization the charge as k+exits the axon from +40 mV to à ¢Ã¢â€š ¬Ã¢â‚¬Å"65mV.

Home Schooling And Educating Children At Home

One of the major advantages of homeschooling is that it allows parents to be profoundly involved in the instruction of their kid. Lyman ( 1998 ) and Mayberry ( 1988 ) suggest that parents are interested in homeschooling their kids because of the turning perceptual experience that the school system is unequal in developing kids into high winners and that many schools by and big deliver standardized instruction without respect to the person ‘s endowment and potency. Lyman ( 1998 ) and Mayberry ( 1988 ) write that by supplying their undivided attending to their kids, they are in a better place to acknowledge their kid ‘s possible and promote the kid. In a survey by Lines ( 1991 ) , it was found that about three fourths of the parents who home schooled their kids besides prepared their ain instruction stuffs. Furthermore, in a survey comparing the public presentation of homeschooled kids with the regularly schooled kids, it was found that the former outperformed the latter on many steps ( Ray & A ; Wartes, 1991 as cited in Abell, 2002 ) The 2nd advantage of place schooling is that parents can avoid the disadvantages of modern twenty-four hours public instruction ( Clark, 1994 ) . Clark ( 1994 ) suggests that parents are progressively concerned that many public schools have a batch of offense and other bad pupils can negatively act upon their kids. He suggests that parents feel that because drug usage and force is increasing in many public schools, they are better able to guarantee the safety of their kids by educating them at place. Therefore by homeschooling their kids, parents can guarantee the safety of their kids. Homeschooling is non without its disadvantages and one of the normally quoted disadvantages is that place schooling consumes a batch of clip and the parents do non hold any clip for other activities. For illustration, if a kid has to be homeschooled, one of the parents has to give up work and pass a big portion of the twenty-four hours in learning and tutoring the kid. This may put a major load on the parent and may take to feelings of depression, ennui etc. Furthermore, because the parent may or may non be qualified adequate to learn the kid, he or she may non be in a place to learn every bit good as the instructors in a school where there are different instructors for different topics and are hired by the school based on their makings. The 2nd disadvantage of place schooling is that parents feel that they are paying revenue enhancements and other responsibilities, which go into making public schools, and if they do n't direct their kids to these schools, it would be a waste of the money spent. A related ground is that many parents feel that schools have many installations like research labs and playgrounds that place schooled kids do non hold entree to and hence miss out on several chances to larn and socialise ( Abell, 2002 ) . Another disadvantage of homeschooling is that societal cost of place schooling. Diana Jenkins writes that kids feel the demand to socialise and a major portion of their development is in their ability to interact with other kids of their ain age group. She suggests that kids who are place schooled are non in a place to interact with other kids and frequently feel that they are losing out on a really of import experience. Furthermore, Jenkins besides suggests that a major portion of acquisition is the ability to larn while taking the positions of others into consideration. She suggests that homeschooled kids do non hold the luxury of taking into history other pupils ‘ thoughts and sentiments and hence stop up with cognition that is merely in one way. It appears from the above reappraisal that homeschooling has more disadvantages than advantages and that it may be better for the kids to go to schools than stay at place and survey. However, because many parents feel that public schools have many disadvantages, their concerns can be removed by making better place school partnerships. While traditionally parents have merely dropped their kids at school, and participated in some pupil parent meets, some bookmans have suggested that schools can affect the parents more by back uping them with better instruction resources which they can utilize at place to do place tutoring by them more interesting, and besides ask foring parents to school to take part in synergistic activities with instructors so that instructors can besides profit from some of the cognition that parents have. Another suggestion is that better communicating channels should be created between instructors and parents so that the instructors are cognizant if the kid is tra veling through a hard stage and is underachieving because of that ground, and likewise parents are cognizant if the kid is holding some interaction jobs at school because of some issues at place. This manner the environment at both the school and place can better ( Patrikakau, 2005 ) . Therefore, it is clear from the above the place schooling is popular among many parents because of the feeling among them that public schools have many jobs like offense and make non pay single attending to the pupils like the parents can. However it is besides clear that because parents can non supply many installations like research labs and resort areas and can non assist them with societal interactions with friends and schoolmates, homeschooling may non be a really good thought. It appears that both schools and parents can profit from better coaction between parents and instructors where parents experience safe about their kids and instructors can profit from cognizing more about the pupils from the parents.

Individual Person Essay

1.1 Person – centred is about providing care and support that is centred or focused on the individual and their needs. We are all individual and just because two people might have the same medical condition, for eg.Dementia, it does not mean that they require the same care and support. As a care worker I need to understand what the values are. There are eight person centred values: individuality rights choice independency dignity respect partneship equal opportunities I need to listen to S/U, they know themselves best, even if disagree, the care plan is theirs unless the capasity to understand is diminished and then advice must be sought from other person involved in an S/U‘s support plan,even legal advice should be sought in some ases. 1.2  Explain why person centred values must influence all aspects of social care work. The ‘why’ is because it is embedded in social policy and legislation eg Putting People First, Valuing People Now and the Essential Standards. 1.3  Explain how person centred values should influence all aspects of social care work It’s important to respect the rights of the individual to be at the centre of their own care. This means that workers must focus on what the individual wants and how they want it to be provided. 1.2/1.3 vvv Person-centred care values must influence all aspects of health and social care work. Health and social care should be based on person-centred values, and should be individualised as this is a law requirement (Human Rights Act 1998, Health and Social care Act 2012, Codes of practice for Social Care Workers, etc). If person-centre values that underpin all work in the health and social care sector are followed as they should be then all individuals should feel that and health and social workers ensure that: †¢ the individual is supported in accessing their rights †¢ the individual is treated has an individual †¢ the individual is supported to exercise choice †¢ ensure the individual have privacy if they want it †¢ support the individual to be as independent as possible †¢ treat all individuals with dignity and respect To ensure the above is followed will influence all aspect of health and social care it is important to ensure that all individuals are treated as such and person- centred care should ensure this.

What Three Qualities Do You Think Are Most Necessary for a Good Parent

Nowadays people say that not everyone is capable of upbringing a child. Parenthood, which used to be a natural status for almost anyone, is now the source of long debates among couples and a very profitable field to writers and publishers. First of all, a good parent should be a good listener, a person who understands what his or her child needs. Parents that listen are supportive people who put aside their high expectations and will keep their ears open for their young offspring, ready to advise no matter what. Secondly, patience must characterize every person who is bringing up children. That means that we must be ready to forgive the mistakes of the inexperienced , young children and that we must help them not with violence , arguing and patronizing but by drawing the line, setting the right example and being steady and consistent. Finally, I believe that parents ought not to consider their children as an expansion of themselves. They should not be egocentric and they should find the courage to accept their children’s choices and reactions not as a battle but as if their children are showing them the way to how to be a better parent, teaching them the important values of equality and mutual respect. In conclusion, I think that to be a parent is a life-changing experience and a huge responsibility. After all, the children of today are the parents of tomorow and they should be given the right example to follow later at life. Thalia Procopiu Director of Studies 2011, Greece

Mermaids Existence

How would you react to a statement like that? What is a mermaid? Mermaids are legendary aquatic creature with the upper body ofa female human and the tail ofa fish. Mermaids have dated back over hundreds of thousands of years ago. There have been alleged sightings all over the world. People have claimed to see half human and half fish creatures. Are mermaids a myth or a fact? Scientist think mermaids were creatures who developed from our ancestors, who evolved to the sea habitat.Scientist think mermaids have been around for millions of ears, because of old paintings; drawings of them in books, and fossils they have found connect to the mermaids' existence. Fishermen have found spears in fish while fishing in the center of the ocean. Scientist have also discovered drawings of sculls, shaped like a humans', and webbed hands with finger tips at the end. These discoveries have caused people to believe in the existence of mermaids. Scientists think mermaids evolved from the first humans o n earth, so that they may swim. Dr. Paul Robertson thinks mermaids evolved to the sea so they could get food.Dr. Robertson claims mermaids were creatures who hid to keep from being aten by the Megladon, an enormous prehistoric shark that fed on whales. According to â€Å"Mermaids: A Body Found,† mermaids traveled in groups to protect themselves. Based on their assumptions, mermaids later learned how to protect and defend themselves. They swam the ocean freely with dolphins. Mermaid experts say that the majority of mermaids may be in the warmer waters of the Caribbean and the Mediterranean, but that many have been spotted in the Pacific Ocean and Southern Atlantic.Scientist are still collecting more and more evidence every day to find out if mermaids are a myth or a fact. People have claim that they have evidence of mermaid's existence. In most recent events, there was a mermaid sighting in Kiryat Yam, Israel in May 2013. Shlomo Cohen and his friends was walking along the shor e when they saw a creature they thought was a seal or a lady sun bathing lying on a rock. They were discussing what it could be, while trying to find out where the zoom was on the camera they were recording with. They eventually zoom in and the creature turns around.The creature had human and fish like characteristics. The mysterious animal had hair and arms and a tail. When it notices that it has been spotted, it quickly rushes to the ocean and dives. Kiryat Yam is the only place in the world where a $1 million reward is up for grabs for the first person who can provide conclusive footage capturing a real mermaid. The local government has offered this reward in response to the numerous mermaid sightings there. The existence of mermaids are more believable now with the evidence Shlomo Cohen provided.There nave also been accusations that the government confirms mermaids exist. It is claimed that the National Oceanic and Atmospheric Administration (NOAA) confirmed hat mermaids exist a nd they are increasing in numbers. The National Oceanic and Atmospheric Administration is a federal agency focused on the condition of the oceans and the atmosphere. According to Weekly World News, allegedly that recently the U. S. government has captured 7 mermaids and that they are being kept at an undisclosed aquarium, where they are being studied.President Obama has personally met the mermaids and was quite impressed according to reports. If mermaids did exist on earth, how would they be treated? According to â€Å"Mermaids: A Body Found† mermaids might have been ran into hiding by humans. Could humans have done this long ago? In most sightings, mermaids rush off when they have noticed that they have been spotted. It is very rare to spot a creature of this nature. Could humans coexist with this unique species? Humans would probably hunt down these fascinating, aquatic creatures and sell them to the highest bidder.They might even put them in a tank to show them off as muse um art. Hopefully the existence of mermaids This year, on March 6, 2013, marine geologist, Dr. Torsten Schmidt, released extraordinary footage of what he believes to be a mermaid that he captured on amera during one of his deep sea explorations. Contracted by the Iceland GeoSurvey, Dr. Schmidt and his Danish team worked on â€Å"seismic mapping and sampling of the ocean floor† to locate promising sites for oil and natural gas reserves. At nearly three thousand feet below the ocean's surface, Dr.Schmidt reported not only seeing some interesting phenomenon, but also hearing some remarkable things. After reporting to the Iceland GeoSurvey about the strange sounds he heard when he was scanning the ocean floor, he requested to undertake an investigation, which was declined. â€Å"We were reminded of our confidentiality agreements. And we were told we could not share our recording with anyone else,† Dr. Schmidt told Journalist Jon Frankel on Animal Planet's documentary, â₠¬Å"Mermaids: The New Evidence. † Dr.Schmidt ended up conducting his own investigation where he â€Å"took down two cameras on every dive, Just in case we see them. † Commenting on his footage, Dr. Schmidt said Jon Frankel, â€Å"well I looked at it, and knew I was looking into the face of another intelligent species, like us. † According to the video, â€Å"Mermaids: The New Evidence,† Dr. Torsten Schmidt and his Danish team saw something they thought was a mermaid. While submerge deep nder the sea the crew had been looking for a mermaid. A creature swam by touching the window of the small submarine, while also shaking the submarine.While slowing down the video, you saw that hand did in fact touch the submarines window. The hand had resemblance toa human hand, but had webbing in between the fingers. Also, the skull had a top layer differentiating from a humans. This video had been covered up for years, but was leaked to the media. Could this have been a me rmaid? Based on the evidence of the videos, and interviews IVe watched. The sightings of these mermaids look very factual. Scientist are collecting more and more evidence every day to the existence of mermaids.

Stress Implications for College Students Research Paper

Stress Implications for College Students - Research Paper Example However, this generation has adopted certain ineffective and unconstructive methods to overcome stress and consequently stays more troubled (Bland et al. 362). As a result of majority of students being troubled and stressed out, it raises concern as to what underlying root sources are involved and what solutions shall work best to combat these causes. I believe that the college students of this generation suffer largely from stress because of financial issues, transitional difficulties and technicalities of burdensome study courses. Therefore, after conducting comprehensive research and studying various pieces of literature, this paper has been prepared to identify and analyze most common and major reasons that have exposed college students to stress and anxiety. Masses around the globe have suffered from recessionary downfall and inflationary pressures. Inflation has caused an increase in costs of living and competition, resulting in stressful circumstances for students joining coll ege. The added expenditure of tuition fees, purchase of books and other supplementary necessities covers a substantial proportion of any household income. Consequently, families suffer from liquidity difficulties and students get tensed about their financial burdens being borne by their caretakers. Moreover, if students approach the college trust for financial aid, then it creates a stressful burden of liability that must be eventually repaid and settled by them. In fact, â€Å"62% of students say that over the past three months financial worries have had some/a lot of impact on the stress the experience in their daily life† (MtvU 2). Students, who are already facing increased expectations and demands for academic performances from their families and mentors, also have to go through additional stressful factors pertaining to college studies, including regular tuition fees, study material expenses, hostel or alternate residing arrangements, traveling and entertainment expenses and other miscellaneous outflows that come part and parcel with college life (May & Stephen 264).
