School Attendance And Its Effect On The Student And Their...

Even before a child is born, college looms in the distance. Parents have preconceived ideas about their child’s future, and for some families that includes college. Early education is not nearly as worrisome due to the legislation passed in The United States of America (USA). Laws mandating school attendance have changed over the years; however, ever since 1918 all of the states have created and enforced enrollment laws (Landes Solmon, 55). The USA also funds the public school system, thus eliminating any potential finical issues (Landes Solmon, 59-66). In glaring contrast, the college and university systems have not been fully subsidized nor has the transition into them been paved. The process is extensive and complex, while the controversies are plentiful, thus greatly impacting the students who are applying not only in their high school endeavors but also within their family life. This paper will expose the complications and controversies within the process of applying to college, as well as, describe the effects of this madness on the student and their family.

In a world of twenty-four hour hour news, iPhones, touch screens, and laptops, it is not surprising that each year there are more and more children being exposed to, and welcomed into this technologically advanced society. It is not uncommon to see seven year olds using the newest gadgets with surprising efficiency, however, one must ask themselves what effects this new technology driven world is going to have on the younger generations? Are these kids going to become the most efficient multi-taskers to be seen, or is this boom in technological advance, and the societal pressure to be adept at even the newest technologies going to create a generation of youth who do not know how to get through the day without constant internet feeds and the connectedness to the entirety of the technological world? The effects of this increase in technological use by the younger generations of today’s society must be evaluated, and a few main areas where this change seems to have an influence include the youth’s changing sense of morality, children’s social skill development, and the use of these technological advances to provide more efficient and effective means of learning to children. These areas have all been studied rigorously in the past few years as technology has continued to advance, and work to provide insight into the effects of technology on early childhood development and learning.

Sociology factors Essay Example For Students

Sociology factors Essay 1. (a) Privilege is defined as a favor or right granted to some people, but not to everyone. (b) Power is defined as strength, ability, or a driving force. (c) Difference is defined as the way in which two things are not the same. (d) According to MacIntosh there are two types of privileges. The first is based on what she calls unearned entitlements, which are things that all people should have. Some examples are feeling safe in a public place or working in a place where they feel that they belong and are valued for what they can contribute. The other type of privilege is what MacIntosh calls unearned advantage, and occurs when unearned entitlements are restricted to certain groups. An example would be a white person feeling out of place at a downtown nightclub. (e) The paradox in privilege is that individuals are the ones who experience privilege or the lack of it, but individuals are not what are actually privileged. Instead, privilege is defined in relation to a group or a social category. For example, race privilege is more about white people than it is about white peopl e. Privileges are only granted in society when people identify the individual as belonging to a specific category, race, gender, or cultural background. By saying that oppression is the flip side of privilege the author means that for every social category that is privileged, one or more other categories are oppressed in relation to it. Oppression points toward the social forces that press upon people and hold them back, thus blocking their pursuit of a good life. 2. (a) Capitalism is defined as an economic system based on ownership of resources by individuals or companies and not by the state. Capitalism as it relates to sociology has to do with the fact that it not only produces enormous amounts of wealth, but that it creates extreme levels of inequality among social classes and societies. Capitalism also has made the rich richer and the poor poorer and has opened the gap in the U.S. class system. The matrix of domination says that each particular form of privilege, whether based on race, gender, sexual orientation, class, religion, or ethnicity, exists only as a much larger system of privilege. It works by simplifying and clarifying the gray areas that we encounter in privilege. It allows us to see that each form of privilege exists only in relation to all the rest and keeps us from trying to figure out which is the worst or most oppressive. It states that usually we are both oppressed and not oppressed, privileged and not privileged. 3. (a) Privilege works and exists through social systems and individuals that participate in them. They are dominated by privileged groups, identified with privilege groups, and centered on privileged groups. For example, race privilege happens through systems that are white-dominated, white-identified, and white-centered. (b) Rejection is used in the system of privilege by social groups shunning other social groups. For example, realtors steering blacks away from white neighborhoods and by bankers refusing loans to potential black homebuyers. (c) Exclusion is used in the system of privilege by leaving particular social groups out of events, conversations, and the like. For example, always picking the fat kid last in a game of kickball. (d) Avoidance is used in the system of privilege when people do not acknowledge the presence of another person because of his or her race, gender, social class, economic status, and the like. For example, ignoring some dork at your school when he says hi to you first. (e) Devaluing is used in the system of privilege by not giving someone the credit they deserve for an accomplishment, educational status, or ability. For example, when Asian Americans are treated like computer geeks to be managed for their talents but never allowed to manage themselves or others. And then ultimately to be envied and resented when they excel at particular tasks. (f) Privilege affects people by forcing those trapped in dominant groups to try and fulfill the expectations set forth by their soci al class. For example, men often will deny their own personal needs, not ask for help, live with chronic fear, anxiety, isolation, and loneliness while trying to live up to the mainstream standards of masculinity. (g) Privilege affects organizations, communities, and societies in that it goes virtually undetected and is among our worst kept secrets. It is only every so often that when a scandal explodes onto the front pages of the newspaper that the talk of racial behavior, gender harassment, or any harassment for that matter is even addressed. Most of the time people manage to act as if nothing is wrong and that we are one big happy family. Most organizations fail in the area of diversity because they deal with it badly or not at all, unless a crisis forces the issue. And even then, they only deal with it enough to make it go away. The same goes for communities and societies. 4. Dominant groups do not see privilege as a problem because positions of power tend to be occupied by memb ers of that group. 5. (a) The myth that everything is someones fault stems from our individualistic society that encourages us to think that the social world begins and ends with individuals. For example if we use individualism to explain sexism, it leads us to believe that sexism only exists because men are sexist-have sexist feelings, beliefs, means, and motivations that lead them to behave in sexist ways. Thus, if sexism produces evil consequences it is because men are evil toward women. Therefore everything bad in the world is seen as somebodys fault because they helped to create that image. (b) The path of least resistance refers to the path that a person chooses to take in a given situation or setting that will cause the least amount of attention to be directed at them and will cause the least amount of tension among those present. For example, there are a number of options one could pursue while sitting in a movie theater such as screaming and yelling, undressing, taking out a flashlight and reading the newspaper, or watching the movie silently. All of these except for watching the movie silently would probably cause a scene and eventually some problems with other patrons, therefore most people will take the path of least resistance and sit quietly. 6. (a) Dominant classes get off the hook of racism and classism by saying that they cant talk about it if they cant use the words. The dominant class often blames the victim for racism and classism. (b) Dominant classes choose not to talk about racism and classism. They often discredit words such as privilege, racism, sexism, anti-Semitism, heterosexism, classism, dominance, subordination, oppression, and patriarchy, and twist their meaning or turn them into a phobia all the while trying to make them invisible. .u83dd543759f285fe41d959e0e8e06fc7 , .u83dd543759f285fe41d959e0e8e06fc7 .postImageUrl , .u83dd543759f285fe41d959e0e8e06fc7 .centered-text-area { min-height: 80px; position: relative; } .u83dd543759f285fe41d959e0e8e06fc7 , .u83dd543759f285fe41d959e0e8e06fc7:hover , .u83dd543759f285fe41d959e0e8e06fc7:visited , .u83dd543759f285fe41d959e0e8e06fc7:active { border:0!important; } .u83dd543759f285fe41d959e0e8e06fc7 .clearfix:after { content: ""; display: table; clear: both; } .u83dd543759f285fe41d959e0e8e06fc7 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u83dd543759f285fe41d959e0e8e06fc7:active , .u83dd543759f285fe41d959e0e8e06fc7:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u83dd543759f285fe41d959e0e8e06fc7 .centered-text-area { width: 100%; position: relative ; } .u83dd543759f285fe41d959e0e8e06fc7 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u83dd543759f285fe41d959e0e8e06fc7 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u83dd543759f285fe41d959e0e8e06fc7 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u83dd543759f285fe41d959e0e8e06fc7:hover .ctaButton { background-color: #34495E!important; } .u83dd543759f285fe41d959e0e8e06fc7 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u83dd543759f285fe41d959e0e8e06fc7 .u83dd543759f285fe41d959e0e8e06fc7-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u83dd543759f285fe41d959e0e8e06fc7:after { content: ""; display: block; clear: both; } READ: Economic Agricultural Statistics Essay

The Wine of Astonishment Essays - Bolo, Bolo Bolo, Earl Lovelace

In Earl Lovelace's book The Wine of Astonishment two main characters arise Bee and Bolo. Bolo's character is a warrior and he directs the people to the path of empowerment by way of the warrior for that is what he knows and who he is. Bee's character is a man of faith, patience, and a man of his people. Bee also chooses a path of empowerment for the people of the village that is defined by his character, he guides the people to the path of faith. The journey in the book has both men put their characters and paths of empowerment to the test. Who succeeds? Patience, a man of faith, and a man of the people are how I describe Bee's charcter in this book. Bee demonstrates his patience when it is tested against Corporal Price. Prince comes to the village to enforce the law against the Spiritual Baptist. Bee decides it is best to practice in the manners of the Catholics and Anglican until he one day starts preaching in the original manner of the Spiritual Baptist. After that vitalizing serm on he continues till Corporal Price raids the church. Bee realizes that for the benefit of his people they, he must wait, be patient till this injustice is lifted to preach again in the Spiritual Baptist way. Bee is truly a man of the people. In the incident when Corporal Prince raids the church Bee's first thoughts were for the people. Bee tells them Brethren, please don't run. Please don't give them the excuse to brutalize you. He knew how the police would act toward the congregation and he wanted to protect his people. Bee puts the people of the village first for he is a man of the people. Bee is a man of faith. He puts his faith in the Spirit, and the people to stay strong. In continuing with the occurrence of the raid from Corporal Prince you can see Bee's faith. The faith Bee has for the Spirit and the people when the congregation is walked though the village after being arrested and Bee joins in the hymn started by Sister Isabel which the whole congregation then joins. The hy mn goes I never get weary yet, I never get weary yet, Forty long years I work in the field, And I never get weary yet. Saying they have done this a long time now and they have still stayed strong. Here Bee puts his faith in the people and the Spirit together from the uniting of the congregation in the song of the Spirit. Bee is a man of faith, his people, and of patience, with these examples you can understand why I characterize Bee in this manner. The first descriptive words you read about Bolo are rising like a spear out of the back row, with the rest of the congregation, to sing the first hymn was Bolo. With a new kind of toughness about him, a warrior still. I would character Bolo as a warrior defiantly. He is a soldier for his people in this time of oppression. Bolo started as a warrior in the beginning and ended as warrior. When he began as a warrior with stickfighting as the book describes Bolo was in Bonasse, the champion stickfighter, the king, leading the village in battle s down the length and breadth of the island. Bolo fought in pride for the warrior inside during those times of stickfighting. Bolo's warrior disposition continued when Corporal Price was transporting the congregation (including Bolo's mother) to the police station for breaking the law of worshiping in the Spiritual Baptist manner. Bolo made a stand for the people he was their soldier willing to fight even being out numbered. The book refers to how Bolo headbutted Price till he went down. At same time Prince was going down the 9 other police office jumped Bolo. He continued to fight and fight till his head was split open by a police officer. Bolo was a warrior no matter the odds he had to face. The last demonstration of Bolo's warrior character was when he stood on the porch with Primus's 2 girls that he had taken earlier. He

A Brief History of the Young Lords

A Brief History of the Young Lords The Young Lords was  a Puerto Rican political and social action organization that began on the streets of Chicago and New York City in the late 1960s.  The organization disbanded by the mid-1970s, but their radical grassroots campaigns had long-lasting impacts. Historical Context In 1917, the U.S. Congress passed the Jones-Shafroth Act, which granted U.S. citizenship to citizens of Puerto Rico. That same year, Congress also passed the Selective Service Act of 1917, which required all male U.S. citizens between the ages of 21 and 30 to register and potentially be selected for military service. As a result of their newfound citizenship and the extension of the Selective Service Act, approximately 18,000 Puerto Rican men fought for the U.S. in World War I.   At the same time, the U.S. government encouraged and recruited Puerto Rican men to migrate to the U.S. mainland to work in factories and shipyards.  Puerto Rican communities in urban areas like Brooklyn and in Harlem grew, and continued to grow after World War I and during World War II. By the late 1960s, 9.3 million Puerto Ricans lived in New York City. Many other Puerto Ricans migrated to Boston, Philadelphia, and Chicago. Origins and Early Social Activism As Puerto Rican communities grew, dwindling economic resources like proper housing, education, employment, and healthcare became increasingly problematic. Despite their involvement in the wartime labor force and  participation in the front lines of both world wars, Puerto Ricans faced racism, lower social status, and limited employment opportunities. In the 1960s, young Puerto Rican social activists gathered in the Puerto Rican neighborhood of Chicago to form the Young Lord Organization. They were influenced by the Black Panther Partys rejection of a white-only society, and they focused on practical activism such as cleaning up neighborhood garbage, testing for disease, and providing social services. The Chicago organizers provided a charter to their peers in New York, and the New York Young Lords was formed in 1969. In 1969, the Young Lords were described as a ‘’street gang with a social and political conscience.’’ As an organization, the Young Lords were considered militant, but they opposed violence. Their tactics often made news: one action, called the â€Å"Garbage Offensive,† involved lighting garbage on fire to protest the lack of garbage pickup in Puerto Rican neighborhoods. On another occasion, in 1970, they barricaded the Bronxs decrepit Lincoln Hospital, collaborating with likeminded doctors and nurses to provide proper medical treatment to community members. The extreme takeover action ultimately led to the reformation and expansion of Lincoln Hospitals health care and emergency services. Birth of a Political Party As membership grew in New York City, so did their strength as a political party. In the early 1970s, the New York group wanted to disconnect with a perceived street gang held by the Chicago branch, so they broke ties and  opened offices in East Harlem, the South Bronx, Brooklyn, and the Lower East Side.   After the split,  the New York City Young Lords evolved into a political action party, becoming known as the  Young Lords Party. They developed multiple social programs and established branches across the Northeast. The Young Lords Party developed a political structure that resembled a complex hierarchy of parties, within the organization aligned with top-down goals. They used an established set of unified goals and principles that guided multiple organizations within the party called the 13 Point Program. The 13 Point Program The Young Lords Partys 13 Point Program established an ideological foundation that guided all organizations and people within the party. The points represented a mission statement and a declaration of purpose: We want self-determination for Puerto RicansLiberation of the Island and inside the United States.We want self-determination for all Latinos.We want liberation of all third world people.We are revolutionary nationalists and oppose racism.We want community control of our institutions and land.We want a true education of our Creole culture and Spanish language.We oppose capitalists and alliances with traitors.We oppose the Amerikkkan military.We want freedom for all political prisoners.We want equality for women. Machismo must be revolutionary... not oppressive.We believe armed self-defense and armed struggle are the only means to liberation.We fight anti-communism with international unity.We want a socialist society. With the 13 Points as a manifesto, sub-groups within the Young Lords Party formed. These groups shared a broad mission, but they had distinct goals, acted separately, and often used  different tactics and methods.   For example, the Womens Union sought to aid women in their social struggle for gender equality. The Puerto Rican Student Union focused on recruiting and educating high school and college students. The Committee for the Defense of the Community focused on social change, establishing nutrition programs for community members and taking on big issues like access to health care. Controversy and Decline As the Young Lords Party grew and expanded  their operations, one branch of the organization became known as the Puerto Rican Revolutionary Workers Organization. The PPRWO was explicitly anti-capitalist, pro-union, and pro-communist. As a result of these stances, the PPRWO came under scrutiny by the U.S. government and was infiltrated by the FBI. The extremism of certain factions of the party led to increased member infighting. The Young Lords Partys membership declined, and the organization was essentially disbanded by 1976.   Legacy The Young Lords Party had a brief existence, but its impact has been long-lasting. Some of the radical organizations grassroots social action campaigns resulted in concrete legislation, and many former members went on to careers in media, politics, and public service.   Young Lords Key Takeaways The Young Lords Organization was an activist group (and, later, a political party)  aimed at improving social conditions for Puerto Ricans in the United States.Grassroots social campaigns like the Garbage Offensive and the takeover of a Bronx hospital were controversial and sometimes extreme, but they made an impact. Many of the Young Lords activist campaigns resulted in concrete reforms.  The Young Lords Party began to decline  in the 1970s as increasingly extremist factions broke off from the group and faced scrutiny from the U.S. government. The organization had essentially disbanded by 1976.

Impact of IT Outsourcing and Off-shoring on Companies Research Paper

Impact of IT Outsourcing and Off-shoring on Companies - Research Paper Example Impact of IT Outsourcing and Off-shoring on Companies Information technology is an important factor in the modern world given the advance in technology. It helps firms innovate and produce high quality products that meet customer needs and demands. Due to changing business environment, firms have found it necessary to reduce operating costs while exploiting the comparative advantages of human IT skills offered by other countries (Manaschi 87). Therefore, companies have opted to outsource critical IT skills from other firms from other nations that are endowed with the expertise. In spite of the benefit of cost reduction and improved operations, IT outsourcing poses security and generic risk issues to the firm (McKendrick 130). If these issues are well managed, the outsourcing firm is likely to benefit through increased innovativeness and high product quality that could positively improve customer satisfaction hence increasing customer loyalty. This study examines outsourcing and explores outsourcing as applied in IT organizations. Outsourcing is the act in which a company or an organization pays another firm to produce goods or offer services on their behalf (Blokdjik 98). In many cases, the company could have produced the goods or offered the service themselves but sometimes it involves higher costs. Off-shoring on the other hand is a business process that companies use when they decide to relocate their operations to lower cost locations, mainly overseas.

Bristol University SWOT and PEST Analysis Essay

Bristol University SWOT and PEST Analysis - Essay Example Another strength is the financial stability and management. According to the annual records of the Bristol University in 2014, the university’s the Bristol’s financial statement shows cash flow generation of 10.1% in 2013/2014. This is a strong evidence on the university’s strong financial stability. The strong financial stability and management enhances Bristol University’s ability to invest in the innovation while also supporting the other areas of the growth (Shattock, 2015).   Additionally, the university’s simplicity in terms of scoring and structure makes it easy in charting the scores of the individual over time. This is specifically important in case studies. Other strengths include; cultural and linguistic diversity of the students/city/staff and the increasing international, responsive to change, increasing amount and the quality of the applied research, and home student recruitment and demand (Dyson, 2000).WeaknessesThe tightly constrai ned city center site where the Bristol University is located makes it hard for it to meet the current requirements for the space efficiency. This makes it hard for the new buildings to fit in. Another weakness is the university’s poor adaptability of the processes to changes and demand, and the unnecessary bureaucracy (Clark, 2014). This makes it hard in securing the lean processes in the organisation. Other weaknesses include; few endorsements, strains of expansion, and lack of the external clout.The increased international recruitment to Bristol University.

The Characteristics And Applications Of Manets Computer Science Essay

The Characteristics And Applications Of Manets Computer Science Essay Chapter 1 The advent of ubiquitous computing and the creation of new, powerful, efficient, portable computing devices have focused the importance of mobile and wireless networking. Mobile wireless communications and networking is an emerging technology that allows users to access information and services electronically at any time, regardless of their geographic positions. There are two types of wireless networks: infrastructure based wireless networks and infrastructure-less wireless networks (ad hoc networks). The infrastructure based wireless networks have routers and gateways as stationary components to which mobile nodes within the network connect. Mobile nodes connect to the nearest base station whose communication radius covers the area that the nodes are in. When a mobile node moves out of the coverage area of a base station, it is handed off to a new base station that covers the area that the node is now in. Cellular phone technology is a typical example of an infrastructure network. The second type of wireless network is the ad hoc network. The term ad hoc tends to different forms and can be mobile, stand alone, or networked[1]. A Mobile Ad hoc NETwork (MANET) is a self-organized wireless communication short lived network that contains collection of mobile nodes. The mobile nodes communicate with one another by wireless radio links without the use of any pre-established fixed communication network infrastructure or centralized administration, such as base stations or access points, and with no human intervention [2, 3, 5, 6, 7]. Self-organizing means that MANETs have the ability to spontaneously form a network of mobile nodes or hosts, merged together or partitioned into separate networks on-the-fly depending on the networking needs and dynamically handle the joining or leaving of nodes in the network. The major objectives of self organized MANET are: scalability, reliability, and availability. Mobile nodes are low capacity autonomous computing devices that are capable of roaming independently. Because of the fact that nodes are mobile, the network topology changes rapidly and unpredictably over time. Each mobile node acts as both a host and a specialized router to relay information (forward packets) to other mobile nodes. The success of the communication highly depends on the other nodes cooperation. The nodes themselves are responsible for dynamically discovering other nodes to communicate in radio range. Figure 1.1: Heterogeneous Mobile Ad hoc Network (MANET) Typical MANET nodes are Laptops, PDAs, Pocket PCs, Cellular Phones, Internet Mobil Phones, Palmtops or any other mobile wireless devices. These devices are typically lightweight and battery operated. Figure 1.1 illustrates an example of a heterogeneous MANET and its communication technology which contains one PDA, one pocket PC, one laptop, one mobile phone and one mobile device. Since mobile phone is outside pocket PCs transmission range, the data from pocket PC to mobile phone must be retransmitted by laptop. 1.1.1 Characteristics of MANETs The main characteristics of MANETs are: the complete lack of centralized control, lack of association among nodes, rapid mobility of hosts, frequent dynamically varying network topology, shared broadcast radio channel, insecure operating environment, physical vulnerability and limited availability of resources, such as CPU processing capacity, memory power, battery power, and bandwidth [2, 6, 7, 8]. Dynamic Network Topologies: The nodes in MANETs are free to move independently in any direction. The networks wireless topology may change frequently and randomly at unpredictable times and primarily consists of bidirectional links. Low Bandwidth: These networks have lower capacity and shorter transmission range than fixed infrastructure networks. The throughput of wireless communication is lesser than wired communication because of the effect of the multiple access, fading, noise, and interference conditions. Limited Battery Power: The nodes or hosts operate on small batteries and other exhaustible means of energy. So, energy conservation is the most important design optimization criteria. Decentralized Control: Due to unreliable links, the working of MANET depends upon cooperation of participating nodes. Thus, implementation of any protocol that involves a centralized authority or administrator becomes difficult. Unreliable Communications: The shared-medium nature and unstable channel quality of wireless links may result in high packet-loss rate and re-routing instability, which is a common phenomenon that leads to throughput drops in multi-hop networks. This implies that the security solution in wireless ad hoc networks cannot rely on reliable communication. Weak Physical Protection: MANETs are more prone to physical security threats than fixed-cable nets. Mobile nodes are usually compact, soft and hand-held in nature. Today, portable devices are getting smaller and smaller. They could get damaged or lost or stolen easily and misused by an adversary. The increased possibility of different types of attacks should be carefully considered. Scalability: Due to the limited memory and processing power on mobile devices, the scalability is a key problem when we consider a large network size. Networks of 10,000 or even 100,000 nodes are envisioned, and scalability is one of the major design concerns. 1.1.2 Applications of MANETs There are many applications of MANETs. The domain of applications for MANETs is diverse, ranging from small, static networks that are constrained by power sources to large-scale, mobile, highly dynamic networks. Significant examples include establishing survivable, efficient, dynamic communication for: network-centric military/battlefield environments, emergency/rescue operations, disaster relief operations, intelligent transportation systems, conferences, fault-tolerant mobile sensor grids, smart homes, patient monitoring, environment control, and other security sensitive applications. Most of these applications demand a specific security guarantees and reliable communication [2, 5, 7, 9]. Some well known applications are: Military Tactical Operations: For fast and possibly short term establishment of military communications and troop deployments in hostile and/or unknown environments. Search and Rescue Operations: For communication in areas with little or no wireless infrastructure support. Disaster Relief Operations: For communication in environments where the existing infrastructure is destroyed or left inoperable. Law Enforcement: For secure and fast communication during law enforcement operations. Commercial Use: For enabling communications in exhibitions, conferences and large gatherings. For some business scenarios, the need for collaborative computing might be more important outside office environments than inside a building. After all, it is often the case where people do need to have outside meetings to cooperate and exchange information on a given project. 1.1.3 Routing in MANETs Node mobility has a large impact on the behavior of ad hoc networks. The nodes in the network are free to move independently in any direction to change the routes. Every node in MANET acts as a router that discovers and maintains routes in the network. The nodes themselves are responsible for dynamically discovering other nodes to communicate. When a node wants to communicate with a node outside its transmission range, a multi-hop routing strategy is used which involves some intermediate nodes. The networks wireless topology changes frequently and randomly at unpredictable times. In order to allow truly spontaneous, infrastructure-less networking and efficient end-to-end communication with the network of nodes, a routing protocol is used to discover the optimal routes between the nodes. Hence, the primary challenge is to establish a correct and efficient route between a pair of nodes and to ensure the correct and timely delivery of packets. The routing protocols meant for wired networks cannot be used for MANETs because routing in MANETs is nontrivial due to the highly dynamic nature of the mobile nodes. Route construction should be done with a minimum of overhead and bandwidth consumption. An extensive number of research works on designing the various routing protocols proactive, reactive, and hybrid have been proposed in the literature and widely evaluated for efficient routing of packets [3]. However, they do not address possible threats aiming at the disruption of the protocol itself and often are vulnerable to node misbehavior. A node dropping all the packets is considered as malicious node or selfish nodes. A malicious node misbehaves because it intends to damage network functioning. A selfish node does so because it wants to save battery life for its own communication by simply not participating in the routing protocol or by not executing the packet forwarding. A malicious node could falsely advertise very attractive routes and thereby convince other nodes to route their messages via that malicious node. With the lack of a priori trust between nodes, current ad hoc routing protocols are completely insecure and optimized only to spread routing information quickly as the network changes [4]. 1.1.4 Security in MANETs Security is an essential service for MANET because all network services are configured on-the-fly. When the security of a given MANET architecture is not properly designed from the beginning, it is difficult to achieve the security goals in practical networks during the network deployment [12, 13]. To secure a MANET, one usually considers the objectives confidentiality (privacy), availability, integrity, authenticity and non-repudiation. Confidentiality ensures that secret information in the network is never revealed to unauthorized nodes. i.e. the assurance that data is not disclosed to unauthorized parties. Availability ensures that the requested network services, such as bandwidth and connectivity, are available in a timely manner and service is not denied to authorize users. i.e. the assurance that data is readily accessible. Integrity ensures that message or packet being transferred between nodes is not altered or corrupted. i.e. the assurance that data is genuine. Authentication ensures the correct identity of the peer node it is communicating with. Non-repudiation ensures that the originator of a message cannot falsely deny having sent the message. i.e. the assurance that a node cannot later deny the data was sent by it. Node mobility in a MANET poses many security problems and vulnerable to different types of security attacks than conventional wired and wireless networks due to their open medium, dynamic network topology, absence of central administration, distributed cooperation, constrained capability, and lack of clear line of defense. The unconstrained nature of a wireless medium of MANETs allows the attackers for interception, injection, and interference of communication. Without proper security, mobile hosts are easily captured, compromised and hijacked by malicious nodes. Malicious nodes behavior may deliberately disrupt the network so that the whole network will be suffering from packet losses. Damages include leaking secret information, message contamination and node impersonation. Before MANETs are successfully deployed, security issues must be addressed. Usually, cryptographic techniques are used for secure communications in wired and wireless networks. The method of using security solutions of traditional wired networks is not suitable for providing security in MANETs. The main problem of any public-key based security system is to make each users public key available to others in such a way that its authenticity is verifiable. Conventional security solutions to provide public key management is implemented with public key infrastructure (PKI), in which a trusted third party (TTP) holds the public key certificates of all participating entities and acts as an online certification authority (CA) to provide a public key verification service. MANETs do not provide on-line access to trusted authorities or to centralized servers. Implementing public key management and certificate distribution is more challenging due to the problematic key exchange, session handling , absence of any infrastructure and centralized services, frequent node mobility, wireless link instability, possible network partitions, and configuration of all network services on-the-fly. For these reasons, traditional security solutions that require on-line trusted authorities or certificate repositories are not well suited for securing MANETs. Use of public key cryptography and certificates is one of the effective ways of securing a MANET. The main security problems that need to be dealt with in MANETs are: the secure storage of key/data in the devices; the authentication of devices that wish to communicate to each other; the secure key establishment of a session key among authenticated devices; and the secure routing in multi-hop networks [4]. 1.1.5 Security Attacks in MANETs Security means protecting the privacy (confidentiality), availability, integrity and non-repudiation. Security implies the identification of potential attacks, threats and vulnerability of a certain system from unauthorized access, use, modification or destruction. A security attack is any action that compromises or bypasses the security of information illegally or in an unauthorized way. The attack may alter, release, or deny data [10, 11, 14]. The attacks on the MANETs can be broadly classified into two categories: passive attacks and active attacks as shown in Figure 1.2. Both passive and active attacks can be made on any layer of the network protocol stack [3]. Figure 1.2: Types of security attacks Passive Attacks: A passive attack attempts to retrieve valuable information by listening to traffic channel without proper authorization, but does not affect system resources and the normal functioning of the network. Figure 1.3 shows a schematic description of a passive attacker C, eavesdropping on the communication channel between A and B. Figure 1.3: A passive attack The different types of passive attacks are eavesdropping (information leakage), traffic monitoring, and analysis. Passive attacks are very difficult to detect because they do not involve any alteration of the data. The emphasis in dealing with passive attacks is on prevention rather than detection. One of the solutions to the problem is to use powerful encryption mechanism to encrypt the data being transmitted, thereby making it impossible for the attacker to get useful information from the data overheard. Eavesdropping (information leakage) is a very easy passive attack in the radio transmission environment, where malicious nodes capture all traffic, including routing traffic, and thus obtain routing information. When one sends a message over the wireless medium, an attacker equipped with a suitable transceiver in the radio range of the transmission can intercept and capture all traffic including the sensitive routing information. The sender or the intended receiver has no means of detecting if the transmission has been eavesdropping in the radio transmission by the adversary who do not physically connect to the medium. Traffic monitoring collects information of network nodes such as the identities and locations of nodes and the amount of data transmitted among them. Traffic analysis means that a malicious node analyses all captured/received traffic in order to extract information about the characteristics of transmission, such as, which nodes are communicating frequently or exchange huge amounts of data. This information could be exploited to launch further attacks. Active Attacks: An active attack attempts to alter or destroy system resources and the data being exchanged in the network by injecting or modifying arbitrary packets, thus gain authentication and tries to affect or disrupt the normal functioning of the network services. An active attack involves information interruption, modification, or fabrication. Figure 1.4: An active attack As shown in Figure 1.4, an active attacker C can listen, modify, and inject messages into the communication channel between A and B. Active attacks can be either internal or external [5]. External attacks are carried out by nodes that do not belong to the network. These attacks are launched by adversaries who are not initially authorized to participate in the network operations and access the resources without authorization. External attacks usually aim to cause network congestion, denying access to specific network function or to disrupt the whole network operations. Bogus packets injection, denial of service, and impersonation are some of the attacks that are usually initiated by the external attackers. Internal attacks are from compromised nodes that are part of the network. Compared with external attacks, internal attacks are more serious and hard to detect because the attackers know valuable and secret information from compromised or hijacked nodes and possess privileged access rights to the network resources. Active attacks, whether carried out by an external adversary or an internal compromised node, involves actions such as impersonation (masquerading or spoofing), modification, fabrication and replication. The active attacks are classified into different types: MAC Layer attacks, Network Layer attacks, Transportation Layer attacks, Application Layer attacks and Multi Layer attacks as shown in Figure 1.5. MAC Layer Attacks: Jamming Attack In this form of attack, the adversary initially keeps monitoring the wireless medium in order to determine the frequency at which the receiver node is receiving signals from the sender. It then transmits signals on that frequency so that error free reception at the receiver is hindered [3]. Figure 1.5: Classification of security attacks Network Layer Attacks: Wormhole Attack In this attack, two compromised nodes can communicate with each other by a private network connection. A malicious node captures packets from one location in the network and tunnels these packets to the other malicious node at another location. The second malicious node is then expected to replay the tunneled packets locally. The tunnel between two colluding attackers is referred to as a wormhole. The wormhole can drop packets by short-circuiting the normal flow of routing packets or it can selectively forward packets to avoid detection [15, 16, 17]. Black Hole Attack A black hole attack is a kind of denial of service where a malicious node attracts all packets by falsely claiming (advertising) a shortest path to the destination node whose packets it wants to intercept and then absorb them without forwarding to the destination [15]. i.e. a malicious node falsely advertise itself as having the shortest path to the destination node whose packets it wants to intercept causing all nodes around it to route packets towards it. Sinkhole Attack In a sinkhole attack, the adversarys goal is to attract nearly all the traffic from a particular area through a compromised node, creating a metaphorical sinkhole with the adversary at the center. Because nodes on or near the path that packets follow have many opportunities to tamper with application data [18, 19]. One motivation for mounting a sinkhole attack is that it makes selective forwarding trivial by ensuring that all traffic in the targeted area flows through a compromised node, an adversary can selectively suppress or modify packets originating from any node in the area. Gray Hole Attack A gray hole attack is a variation of the black hole attack, where the malicious node is not initially malicious, it turns malicious sometime later. In this attack, an attacker drops all data packets but it lets control messages to route through it [20, 21]. This selective dropping makes gray hole attacks much more difficult to detect than black hole attack. Byzantine Attack In this attack, a compromised intermediate node or a set of compromised intermediate nodes works in collusion and collectively carries out attacks such as creating routing loops, routing packets on non-optimal paths, and selectively dropping packets. Byzantine failures are hard to detect because throughput of attacker nodes as same as other nodes [22]. Information Disclosure Attack In this, a compromised node attempts to reveal confidential or important information regarding the network topology (the structure of the network), geographic locations of nodes, or optimal routes to unauthorized nodes in the network [7][23]. Resource Consumption Attack In this attack, a malicious node deliberately tries to consume/waste away the resources of other nodes present in the network by requesting excessive route discovery (unnecessary route request control messages), very frequent generation of beacon packets, or by forwarding unnecessary packets (stale information) to that node. The resources that are targeted are battery power, bandwidth, and computational power, which are only limitedly available in MANETs [24, 25]. Man-In-The-Middle Attack In this, the attacker exists as a neighbor to any one node in the routing path and alters data that is being transmitted and injects modified packet into network. i.e. a malicious node impersonates the receiver with respect to the sender, and the sender with respect to the receiver, without having either of them realize that they have been attacked with an intension to read or modify the messages between two parties [12]. Neighbor Attack In this attack, upon receiving a packet, an intermediate node records its ID in the packet before forwarding the packet to the next node. An attacker, however, simply forwards the packet without recording its ID in the packet to make two nodes that are not within the communication range of each other believe that they are neighbors (i.e., one-hop away from each other), resulting in a disrupted route. The goal of neighbor attackers is to disrupt multicast routes by making two nodes that are in fact out of each others communication range believe that they can communicate directly with each other [15]. Routing Attacks In this attack, attackers try to alter the routing information and data in the routing control packet. There are several types of routing attacks, such as routing table overflow attack, routing table poisoning attack, packet replication attack, route cache poisoning attack, and rushing attack, mounted on the routing protocol which are aimed at disrupting the operation of the network [3]. Ã ¢-Â ºRouting Table Overflow Attack In this attack, an adversary node advertises routes to non-existing authorized nodes present in the network. The main objective of such an attack is to cause an overflow of the routing tables, which would, in turn, prevent the creation of entries corresponding to new routes to authorized nodes. Proactive routing protocols are more vulnerable to this attack compared to reactive routing protocols. Ã ¢-Â ºRouting Table Poisoning Attack In this attack, a malicious node sends false routing updates to other uncompromised nodes. Such an attack may result in suboptimal routing, network congestion or even make some part of the network inaccessible. Ã ¢-Â ºPacket Replication Attack In this attack, an adversary node replicates stale packets. This consumes additional bandwidth and battery power resources available to the nodes and also causes unnecessary confusion in the routing process. Ã ¢-Â ºRoute Cache Poisoning Attack This attack occurs when nodes are in the updating mode of their tables route. Information stored in the routing tables deleted, changed, and injected with false information. Ã ¢-Â ºRushing Attack In this case, an adversary can rush some routing packets towards the destination, leading to problems with routing. i.e. an adversary node which receives a route request packet from the source node floods the packet quickly throughout the network before other nodes which also receive the same route request packet can react. On demand routing protocols that use route discovery process are vulnerable to this type of attack [26]. Stealth Attacks Stealth attacks are classified into two classes. The first class of attacks attempts to hi-jack or perform traffic analysis on filtered traffic to and from victim nodes. These attacks are mounted, for example, by the modification of routing information. An attacker can divert traffic by using authentic routing messages to fool honest nodes into disrupting their routing tables. The second class partitions the network and reduces good put by disconnecting victim nodes in several ways. For example, the attacker can route a large amount of data through the victim node. This may totally consume the nodes energy resources or create a perception of unavailability due the large quantities of messages being dropped by the victim. Consequently the node under attack will not be used by neighboring routers and becomes isolated. The methods are referred to as stealth attacks since they minimize the cost of launching the attacks and reduce the visibility of the attacker [27]. Transportation Layer Attacks: Session Hijacking Attack Session hijacking is the major transport layer attack. Here, an adversary takes control over a session between two nodes. Since most authentication processes are carried out only at the start of a session, once the session between two nodes gets established, the adversary node masquerades as one of the end nodes of the session and hijacks the session. Session hijacking occurs on two levels: the network level and application level. Application Layer Attacks: Repudiation Attack Repudiation attack is the main application layer level attack. Repudiation refers to the denial or attempted denial by a node involved in a communication of having participated in all or part of the communication [3]. Non-repudiation is one of the important requirements for a security protocol in any communication network and assures that a node cannot later deny the data was sent by it. Multi Layer Attacks: Multi-layer attacks are those that could occur in any layer of the network protocol stack. Denial of service, impersonation or sybil attack, manipulation of network traffic, device tampering, jellifish attack and eclipse attack are some of the common multi-layer attacks. Denial of Service Attack In this attack, an adversary always attempts to prevent legitimate and authorized users of network services from accessing those services, where legitimate traffic cannot reach the target nodes. Denial of Service (DoS) attacks are against CPU power, battery power and transmission bandwidth. A malicious node may launch a DoS attack against another node by requesting routes from that node, or by forwarding unnecessary packets to that node in an attempt to wear down (draining) the other nodes batteries. A DoS attack can be carried out in many ways and against any layer in the network protocol stack, namely, physical layer, link layer, and network layer [4, 12, 31]. Sybil Attack This attack is also known as masquerade or impersonation or spoofing attack. In this attack, a single malicious node attempts to take out the identity of other nodes in the network by advertising false/fake routes. i.e. an attacker pretends to have multiple identities obtained either by impersonating (forges) other nodes or by making use of false identities. It then attempts to send packets over network with identity of other nodes making the destination believe that the packet is from original source [28]. Sybil attacks are classified into three categories: direct/indirect communication, fabricated/stolen identity, and simultaneity. In the direct communication, Sybil nodes communicate directly with legitimate nodes, whereas in the indirect communication, messages sent to Sybil nodes are routed through malicious nodes. An attacker can fabricate a new identity or it can simply steal it after destroying or temporarily disabling the impersonated node. All Sybil identities can participate simultaneously in the network or they may be cycled through [29]. Misrouting Attack This attack is also known as manipulation of network traffic attack. This is a very simple way for a node to disturb the protocol operation by announcing that it has better route than the existing one. In the misrouting attack, a non-legitimate node redirects the routing message and sends data packet to the wrong destination. This type of attack is carried out by modifying metric value of a route or by altering control message fields of a route or modifying the final destination address of the data packet or by forwarding a data packet to the wrong next hop in the route to the destination [30]. Device Tampering Attack (Weak Physical Protection) Unlike nodes in a wired network, nodes in MANETs are usually compact, soft, and hand-held in nature. They could get damaged or lost or stolen easily and misused by an adversary. In military applications, mobile nodes are subject to capturing, compromising and hijacking. In such hostile environments, it is almost impossible to provide perfect physical protection [3]. Jellyfish Attack A jellyfish attacker first needs to intrude into the multicast forwarding group. It then delays data packets unnecessarily for some amount of time before forwarding them. This result in significantly high end-to-end delays and, thus, degrades the performance of real-time applications [31]. Eclipse Attack A pattern of misbehavior called an eclipse attack, which consists of the gradual poisoning of good (uncompromised) nodes routing tables with links to a conspiracy of adversarial nodes (compromised nodes) [12, 15, 18]. 1.1.6 Security Solutions in MANET Various kinds of security attacks are possible on ad hoc routing. Due to inherent characteristics, MANETs are highly susceptible to malicious attacks. To overcome these attacks, available security solutions are used. Attack prevention measures can be used as the first line of defense to reduce the possibilities of attacks. There are two types of security solutions: preventive and detective to overcome these attacks. Preventive solutions are typically based on message encryption techniques, while detective solutions include the application of digital signature and cryptographic hash functions. The prevention schemes proposed for external attacks are key and trust management, whereas the countermeasures for internal attacks are secure routing protocols [5, 7]. 1.2 Motivation of the Work Providing security for MANETs is a difficult problem. The method of using security solutions of a traditional wired network is not suitable. All those methods require online trusted authority. In contrast with conventional networks, MANETs do not provide on-line access to trusted authorities or to centralized servers. For this reason, key management is particularly difficult to implement in such networks. However, key management is deemed as the fundamental essential part of any secure communication. There are two ways to introduce security in MANETs: 1. through a single authority domain, where certification and keys are issued by a single authority, and 2. through full self-organization, where security does not rely on any trusted authority or fixed server.

This causes a lack of useful information, and seriously harms the child s perception of sex. Although sex is necessary for reproduction, it is also a dangerous act.

The lack of sexual education fabricates a negative environment for sexual activity by creating physical and mental harm, while also promoting rape culture, making it necessary for the federal government to implement an incentivized sexual education program.
