Teaching assistant Essay A child’s main development from a new born baby to a 2 year old infant consists of a completely dependent newborn to a child who can lift their head and crawl within 6 months. Around this age a child’s growth begins to slow down to a weight gain of 450-600 grams a month, to then developing those skills to being able to walk within 2 years. A 3 year old would increase by roughly 1.8 kilograms and 5-8 centimetres, stereotypically they should continue to grow taller and slimmer however this will depend on nutrition and genetic makeup. At the age of 6 a child continues to gain, specifically between 8 – 9 years old. 2. Analyse key social, economic and enviroment factors, which may influence development. Approximately around 2.5 million children in the UK live in poverty, this ineffectively creates a social disadvantage, resulting in parents not being able to provide the necessary nutritional balanced diet because they are unemployed or on a low income. Parents and children within this category tend to live in poor housing, which can lead to overcrowding which lack the physical and personal resources needed for a child’s growth. 3. Describe children’s overall development needs. A child’s environment is a key factor that can prohibit or aid development. A positive environment with love and care will develop their socialising ability into creating relationships with others. Factors such as overcrowding, air, water and noise pollution have been proven to prohibit a child’s growth and development.

Sichuan Province Earthquake Effects On Tourism Tourism Essay

Sichuan Province Earthquake Effects On Tourism Tourism Essay Sichuan province is located in the Sichuans plateau in the inland of Southwest China; it is commonly referred to as the land of abundance. It has an enormous territory and rich in resources and is one of the most ethnically diverse areas in China. This province has several historic and cultural sites and other natural and manmade tourist attraction sites. The attraction sites and the famous Sichuan cuisine normally characterized by hot flavor, and incomparable beauty make the province a wonderland that attracts millions of tourists from all over the world. Sichuan is also a major industrial region in China; the province has both heavy and light industries. Plans were underway of developing this region into a high tech industrial centre. A massive earthquake, the famous Wenchuan Earthquake with a magnitude of 8.0 on the Richter scale, hit western Sichuan, China in 2008. According to official figures, released 65,185 people were confirmed dead. Over 68,636 of them were from Sichuan province, approximately 374,171 of others were reported injured and scores of others missing. Millions of people were left homeless and a lot of private and public property destroyed, the economic loss incurred was approximated to be over  ¥ 1,000 billion. The earthquake extremely affected all economic sectors in the quake-hit areas and tourism was no exception. Study of the impacts of the quake on tourism enhances the hypothesis of tourism and more significantly serving as the basis for planning and policymaking. Problem statement The earthquake is believed to have killed 54 tourists in Sichuan province. During the period, over ten thousand tourists were stranded and over 30 flights and 300 vehicles used to evacuate them. The tourist industry lost over $ 7.24 billion in the earthquake. With regard to the contribution of tourism to the regions economy, there have been major reconstruction efforts after the earthquake. Destructive catastrophes, such as the Boxing Day tsunami in the Indian Ocean (2004), Hurricane Katrina (2005), the Wenchuan Earthquake (2008), the Samoan tsunami (2009), and the Haiti earthquake (2010) have lately put the limelight on natural disasters, with real time TV footage screening the events as they unfold. International media issue warnings to tourists to stay away, while local economies experience immediate and widespread impacts from the loss of tourism earnings, and endure many months of uncertainty before a return to anything resembling normal business operation. Tourism destinations are highly sensitive to interruption by natural disasters because tourism operations are reliant on functioning critical infrastructure, including electricity, sewage, communications and water; lifelines which are inevitably damaged and disrupted for a prolonged period following a damaging event (Ritchie 2009). Flow-on effects from disasters also include significant disruption to the supply and distribution chains of even the most prepared businesses (Lee Harrald 1999). Economic losses are attributable to a decline in damage to infrastructure (Laws et al. 2007). The interdependencies of the tourism industry have been one of its great strengths, allowing it to rapidly expand and diversify. However, natural disasters can produce immediate, cascading failures within the tourism sector that have the ability to reverberate within communities and countries for many months and years. This study highlights physical and social impacts of large magnitude earthquakes. According to Sichuans local media, reconstruction in the Sichuan tourism sector has been separated into three levels. The initial stage was trying to attract the domestic tourists to the quake hit areas, followed by focusing on local tourism enterprises to restore global tourism market. Finally reviving the entire tourism sector by or after the year 2010 and make it the leading sector in the region. This earthquake affected the potential tourists perceptions on the Sichuan tourism many still feel that the destination is not safe enough to visit. The Sichuans tourism agency has to spend a considerable budget to convince the potential tourists that the place is safe to travel and that the attractions are still as appealing as they were before the quake. Objectives of the Research Study The main objective of this study is to investigate the potential tourists perceptions towards the Sichuan tourism after the earthquake. This study has not been carried out there giving rise to the knowledge gap that needs to be filled. The findings from this research will fill this knowledge gap and add to the current literature. Findings from this study will also be very significant in identifying the determinants that can be changed to design the best strategies in order to attract more tourists and satisfy their needs. The Sichuan tourism industry is expected to improve services and develop strategies to attract potential tourists and make them feel comfortable in Sichuan. Specifically the objective of this study is to help understand the potential tourists perception towards the post-earthquake Sichuan tourism, and determine what factors are considered significant by the potential tourists wanting to travel to Sichuan. Conceptual framework Scott, N. Laws, E. (2005). Tourism crises and disasters: Enhancing understanding of system effects. Journal of Travel Tourism Marketing, vol. 19, (3), pp. 151-160. The conceptual framework above articulates a set of complete values for disaster management strategies, to the benefit of tourism businesses and destination bureaus. This model follows a linear crisis procedure that is pre-event, emergency, intermediate, recovery and resolution. It goes further to provide insights for successfully assisting the tourism industry and the government in putting up disaster management strategies. Strategic implementation comprise of disaster communication and control, stakeholder collaboration and resource management. The tourism industry should learn from experiences such as the Sichuan earthquake. The work of emergency organizations as well as tourism organizations become very crucial, while that of tourism enterprises is usually less critical during pre- or post crisis periods. LITERATURE REVIEW 2.1. Historical background of problem area Tourism in the area accounted for 8% of county gross domestic product prior to the earthquake (Lim, 2009). The earthquake cost Sichuan province US$7 billion in lost tourism revenue (Zhiling Xianyu 2009). In contrast to the consequences of the Chi-Chi earthquake, tourism to the area rebounded in less than a year as domestic visitors flocked to see areas devastated by the quake (Lim, 2009). Government investment in the tourism industry in the region hopes to cash-in on the earthquake tourism phenomenon, with work currently taking place on the construction of a number of earthquake museums in the province, and a quake-relief training centre in Beichuan (Zhiling Xianyu 2008; Lim 2009). Local officials hope to increase tourism earnings to as much as 20% of regional GDP. One local Beichuan man describes his feelings about the earthquake; the earthquake was a catastrophe, but it will be good for the tourist industry (Lim 2009). The travel motivations of domestic Chinese tourists include o bserving the power of nature, to pay their respects to the dead, and to be reminded of the frailty of life (Liu 2009). According to various online news reports, as many as 19 million tourists visited Sichuan province during the National Day celebrations this year (Global Times 2009). The business of earthquake tourism, it seems, is booming in devastated parts of the epicentral region. Tourism disaster management Tourism is a deliberate and peacetime activity, is very susceptible to disparities caused by external environments that may compromise the tourist experience (Santana, 2003). Given that perception is reality in the tourism industry, a negative image results from a catastrophe of any kind, even if inexcusable, and will hinder potential tourists and lead to negative buying behavior. Globalization exposes the tourism industry to greater political, economic, social, and technological changes (Ritchie, 2004). Meanwhile, the butterfly effect further magnifies small-scale crises in one part of the world to other parts. Examples can be found among previous events, regardless of type, such as the Wenchuan Earthquake with a magnitude of 8.0 on the Richter scale, hit western Sichuan, China in 2008, and the 2004 Indian Ocean tsunami (Santana, 2003). The negative impact of crises on the tourism industry is more significant among destinations that are highly reliant on tourism as their major sourc e of revenue. The world has become increasingly catastrophe prone (Coombs, 1999: Richardson, 1994) and all the economic sectors are on the edge of chaos, Fink argues (1986), Researchers have provided many definitions for crisis. Faulkner (2001) contended that crises are induced by internal factors, or actions or inactions of the organizations, whereas disasters are by external forces, comprising of natural phenomena. Stafford, Yu, and Armoo (2002) further classified external factors into physical, social, and human environment. According to them natural disasters like those that earthquakes and technological failures are affiliated with crises in the former situation, and confrontations, epidemics and war are allied with crises in the latter situation. Foreign visitors satisfaction Hartman developed a customer satisfaction concept in 1993 that consists of three constructs: the cognitive, affective, and systemic (Hartman, 1993). Customer satisfaction is defined by customers post-purchase assessment of service delivered and comparison of customers expectations and the actual service experience (Hunt 2007).This concept was further refined as the expectancy-disconfirmation paradigm by Oliver (2000), with four elements: pre-purchase expectations, perceived performance, disconfirmation and satisfaction. Several approaches to performance analysis in tourism satisfaction such as expectation-performance, importance-performance, disconfirmation approach, and performance-only approach have been used. In terms of travel, Moutinho (1997) notes that this post-purchase construct is primarily a function of pre-travel expectations and travel experiences. Similarly, Pizam, Neumann, and Reichel (1998) define tourist satisfaction as the results of the comparison between a tourists experience at the destination visited and the expectations about the destination. Tourism researches have been interested in measuring the overall levels of tourism satisfaction with their experiences in particular destinations as well as satisfaction with specific attributes at service encounter level such as in a hotel or at an attraction. Foster (2000) while another focus in studying tourism satisfaction is to determine satisfaction with a series of service encounters as experienced in a hotel, in a travel agency or in a tourist attraction (Macintos, 2002). Research interests in methodologies for studying tourism satisfaction have been comprehensive summarized by Kozak (2001).Tourism satisfaction with a destination has been examined as a gap analysis between pre-travel expectations and post travel experiences (Schofield, 1999). Based on the cumulative nature of tourists experiences, Scott, Tian, Wang, and Munson (2005) developed a tourism satisfaction model. Bowen and Clarke (2002) articulated a context Tourism satisfaction level can be attributed to different destination attributes including tangible produces and prices to intangible service quality and the friendliness of the local people (Ryan,1999). The deliveries of good core services alone cannot guarantee customer satisfaction, and overall satisfaction and repurchase intention are differentially influenced by the various service encounters experienced in a chain of service activities (John Tim 2000). Durocher (1994) argued that the speed of recovery depends on three factors: the extent of damage caused by the natural disaster, the efficiency with which tourism partners bring their facilities back online, and an effective marketing message that clearly states that the destination is available to the public (Durocher). Although the first two factors concern the short-term immediate response, the third involves a long-term continuous process that aims to restore consumer confidence. Conventional approaches to crisis management implicitly assume that the primary goal is to restore the precrisis equilibrium level. However, Faulkner and Vikulov (2001) argued that because of the lingering effect of a disaster, trying to achieve the precrisis equilibrium level could be a redundant (or suboptimal) approach with regard to long-term sustainability. The chaos created by a crisis can therefore lead to a creative process with potential for new configurations (Faulkner Vikulov 2001). In other words, the crisis can be an opportunity for innovation, with the launching of new marketing campaigns and development of new products through cooperation with industry partners. These new products and marketing plans should be tailor-made to attract identified key generating markets, because resources are always limited during hard times. Another important strategy is to nurture a healthy and positive relationship with the major media. From the long-term perspective, the restoration of customer confidence is the focus of post disaster recovery, and this can only be done by building a positive image of the destination (Santana, 2003). By inviting major media to visit the area affected, not only the availability of the destination is demonstrated but also the elimination of travel barriers for potential tourists.Although often associated with enjoyment, pleasure, relaxation, and safety, tourism is by nature an industry susceptible to variations in the external environment, including crises and disasters (Santana, 2003.). In times of unpredictable events, government plays an essential role in the response and recovery stages needed to minimize damage and bring life back to normal (Peterson, 1995). The reaction of government agencies and the tourism industry is a critical topic in tourism crisis management that has not ye t been fully addressed (Faulkner,2001). This study represents one of the first attempts to fill this research gap by examining the post earthquake tourists perceptions of Sichuan tourism. METHODOLOGY The study will be a qualitative research, as the qualitative methods will be more appropriate in understanding meanings and experiences relevant to the research. Quantitative methods might however be used if the need arises. Qualitative methods have however, been criticized for not having the scientific firmness. Some researchers have gone further in an attempt to provide systematic approaches to assess its quality. McInnins-Dittrich (1996), for example, identified several dimensions along with which the reliability of quality studies can be assessed: transferability, dependability, credibility, authenticity, and conformability. Guided by the above-mentioned principles, the research will recognize the importance of providing reliable, verifiable, and credible data. The research design will involve a mixed methods approach to help understand the potential tourists perception towards the post-earthquake Sichuan Tourism. To provide an in-depth interpretation of the aims, certain variables will be identified to ensure that all data is utilized successfully to reach the goals of this study, these variables include visitor characteristics, trip characteristics, satisfaction, factors that influence the visitors decision to visit a destination, and Sichuans tourism marketing image. These variables will be fundamentally developed from the examination of previous literature, and the needs for further research as expressed by Sichuan Tourism Administration. Data collection Secondary and primary data collection methods will be used in the research study. The secondary methods to be employed will include literature review, and policy and legislative analysis. Primary methods will include focus group discussions stakeholder consultations, and focused interviews with key informants, interviews with potential tourists in different regions and surveying the attitudes and beliefs across various regions. Survey Considering the questions to be answered by this research, a comprehensive social cultural instrument will be developed. Perceptions, attitudes, and opinion questionnaire (PAOQ) will be informed by literature review and the social cultural factors that are relevant to the target regions. They will also be scientifically validated before administering them across a representative sample in each target region. Using a likert scale, the PAOQ will be a self-reporting assessment of perceptions, attitudes and the opinions of the potential tourists that will be designed for both domestic and international tourists from different regions. The questionnaire will contain several sections: post earthquake perceptions, the attitudes to the Sichuan tourism, opinion on the required action to promote the tourist attractions. The researcher hopes to administer the questionnaires within group settings. Sampling method will be used for the PAOQ. The researcher aims to administer 500 questionnaires across the targeted regions. The questionnaires distribution will depend on the regions population with regions with the high population getting more questionnaires. The researcher also aims for 50-50 representation of the males and females. The key variable will include gender, education, socioeconomic status, age and rural/ urban. Data analysis The researcher will then analyze the PAOQ data using the statistics package for social sciences version 16. The given variables will be analyzed and their contribution to the topic measured. Frequencies will be used to provide the statistics and graphical displays that will be useful in describing the variables to be measured. Cross tabulation, method will also be employed to measure the association of variables. To investigate the possible gender effects, ANOVAs test will be used and conducted between the men and the women on all dependent variables. Differences between the childhood sexual abuse group and the non- childhood sexual abuse group in interpersonal, social, and dynamic personality will be examined using a one-way ANOVA test. The researcher however has the mandate to use any other data analysis technique depending on the kind of data that will be obtained from the field Summary This chapter has described the methodological approaches that will be used to investigate the main objectives of this study. Both objectives will predominantly use qualitative method but where need be the quantitative methods will be employed. It also explains how data will be collected that is through primary and secondary methods. Further describes the researchers survey. Finally, the methods and tolls of data analysis are fully explained research findings and interpretation will be discussed in the next chapter.

Burst Transmissions Technology And Characteristics

Burst Transmissions Technology And Characteristics Strategy is the art of making use of time and space. I am less concerned about the latter than the former. Space we can recover, lost time never Napolean Benoparte BURST TRANSMISSIONS TECHNOLOGY 1. Having understood the surveillance network requirements, carried out an analysis of our present surveillance network and identified burst transmission as an alternative means to pass the information to surveillance centres, the aim of this part is to analyse the effectiveness of burst transmission technology for the networking of surveillance resources in desert terrain for offensive operations. BURST TRANSMISSIONS TECHNOLOGY AND CHARACTERISTICS 2. Electromagnetic waves, like all other waves are characterized by their frequency and intensity. The electromagnetic spectrum consists of electromagnetic waves of all possible frequencies. This spectrum extends from the VHF ranges to mill metric waves in military  [1]  . The electromagnetic waves do not follow the man made rules/ international boundaries. They can be easily intercepted and analysed to get intelligence about the enemy  [2]  . Today we are using VHF radio as the primary means of passing our surveillance information to our surveillance centres. 3. Working Of Burst Transmission. The term burst transmission involves compressing the data, high data signaling rate and transmitting in short bursts which are not easily detectable by the enemy. Burst transmission basically compresses the same data and sends it in bursts. This technology is very popular among the spies and military personals due to its advantages  [3]  . 4. A radio packet is a short transmission in burst form of data that occurs on a radio channel. The burst data may have different types of radio characteristics i.e the modulation type, error coding, preamble length and transmission guard time periods. It contains reference sequences in form of a preamble and possible a midamble, control information and payload of data. The combination of all the above mentioned characteristics is called the burst profile  [4]  . A burst set is a single burst transmission packet and it has the preamble along with one or more bursts of data. The bursts of information will contain packets having different modulation and coding. A burst frame contains the complete set of information for a burst transmission. The bursts within a burst set are sequenced according to their modulation complexity. With the bursts having lower complexity modulation beginning located at the beginning of the radio packet. Subsequent bursts can use modulation types with high er complexity (e.g. QPSK, QAM). This allows subscriber stations to receive and decode all the bursts up to the burst with the highest modulation type it can receive  [5]  . 5. To enable the receiving device to lock on, the radio bursts start with a sequence of bits i.e a preamble that the receiving device can recognize and lock onto. On locking onto the preamble, it knows the location of the rest of the packets. For longer radio bursts, midamble sequences may be inserted which helps the receivers in the decoding of bursts. A midamble is defined as a sequence of bits which the receiving device can recognize and lock onto to assist in decoding the bits surrounding it. Sending preambles and midambles frequently give the user an increased mobility. Data packets may be inserted within the payload of a single radio burst. They may be located at one place or divided or fragmented over several radio packet bursts or multiple small packets and packed into the burst payload. The figure below depicts an example of a radio packet which is made of a preamble and a set of bursts  [6]  . https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_Vf0i9j8ADBSD2nbXaZMnCKktv5TapWqZVKO6EbqgLnF0JzoqqlOj51i-vAL7sOad5sKt8Ik6l_29qfWxnUoePiUkWnEcdoVdkn1t3u-um0nK8uP0UysB_viyghkYhyphenhyphen_WzxyrkvTmGU5O/s400/1.jpg Figure Radio Packet Containing Preamble And Data 6. Characteristics Of Burst Transmission Technology. It is a relatively high bandwidth transmission over short period of time  [7]  . Very high data signaling rate with very short transmission time  [8]  . Data is stored for a given time are sent at 10 to more than 100 times the normal rates, recorded when received and then slowed down to normal rate for use by the receiver  [9]  . It has Low Probability of Intercept and Low Probability of Detection  [10]  . The actual transmission time is very less which make it difficult to detect. The download time might use 2Mbit/s on a average while having peaks bursting up to 2.4 Mbits/s  [11]  . Data transmission is interrupted at intervals  [12]  . Data is digitally encrypted  [13]  . 7. Limitation Of Burst Transmission Technology. The system is dependent on the radio interface for transmission of data. Line of sight is still a major consideration for VHF transmission. HF transmission is recommended to obviate the problem  [14]  . The error in data during transmission / reception can lead to error at the receiving end. 8. The burst transmission is a suitable means to transmit data over a long range in secure mode due to the following reasons:- The transmission takes place for a short period i.e only when data has to be passed, thus it has a Low Probability of Intercept and Low Probability of Detection. It is difficult for enemy Direction Finding systems to locate the radio as it transmits for a short duration that is only when required. MODELS IN USE 9. The burst transmission technology is one of the technologies being used in the armed forces of other countries for networking. The Harris RF- 3700, Falcon II AN/PRC 150 (c), GRA -71 all of USA, GRC -6400 400W HF Radio System, Tadiiran HF -6000 Radio System of Israel and HF 7000 of Germany are examples of use of burst transmission in military communication. Similar equipments using burst transmission have been designed and developed in India by Bharat Electronic Limited. 10. Harris RF 3700 Harris Universal Transmission Software (HUITS). It is a Microsoft-Windows 2000/XP compatible software being used by United States forces for fast and reliable transmission of high resolution digital imagery, motion video clips and other data difficult tactical communication channels.

Falcon II AN/PRC 150 (c). It is a software defined HF radio system being used by United States forces for tactical communication including data transfer. It uses burst transmission and has high speed modem for data transfer. It can be interfaced with US Tactical Internet without any additional boxes  [16]  . 12. GRC -6400 400W HF Radio System. It is a 400W HF radio system being used by Israel for tactical communication including data transfer. It uses burst transmission and has an adaptive high rate modem up to 4.8 Mbit/s for data transfer  [17]  . 13. Tadiiran HF 6000. It is a HF radio system being manufactured by Elbit Systems, Israel for tactical communication including data transfer. It can also use burst transmission for data transfer. It is available in fixed station, ship, vehicle, man pack and high power versions  [18]  . 14. HF 7000. It is a HF radio system being used in Germany for tactical communication including data transfer. It uses burst transmission for fast data transfer. It is available in fixed, semi mobile base, vehicle and man pack versions  [19]  . EQUIPMENT AVAILABLE FROM BHARAT ELECTRONIC LIMITED 15. There are similar equipments being made in India by Bharat Electronic Limited. However they have not been exploited for surveillance network till today. The equipments available from Bharat Electronic Limited are discussed in succeeding paras. 16. Spurt Message Alphanumeric Radio Terminal (SMART). It is a message processing and transmission equipment based on a microprocessor for field use. It provides reliable burst transmission capability and reduces radio channel occupancy time with in reduction in probability of interference and jamming. It has a facility to prepare messages off air with the alphanumeric keyboard and display unit of the equipment. It supports both free and formatted text messages and has built-in encryption for text message. Voice Links on HF Radio can be done using the built-in modem. It can operate in poor channel conditions. A hard copy of messages can be taken by connecting a printer to a serial port ASCII printer. The terminal can also be optimized for a particular application. Interface with PC is also available as an optional S/W module to handle messages having relatively longer length, thus giving an user friendly edit capability. It is being used by the Mobile Observation flights of Indian Ai r Force  [20]  . 17. Hand Held Radio Terminal (HART). It is a small size, light weight and low power consuming terminal used for preparation and transmission of alphanumeric messages digitally. Its ideal for field use. The terminal reduces the chances of interference and jamming by providing reliable burst transmission capability and reduce radio channel occupancy time. Messages are prepared off-air with the alphanumeric keyboard. Messages reception is automatic  [21]  . 18. HF Trans receiver. It is an advanced lightweight 20W HF portable radio set. It meets all the requirements of short-range communication to operate in crowded HF band. It provides voice, data, telegraphy and flash (burst) message communication. Communication reliability is improved by means of automatic link establishment, which enable real-time selection of optimum channel frequency  [22]  . 19. Stand Alone Communication Unit (SACU). It is a high speed, secure data communication equipment using burst communication technique with built in encryption method and modems contained in a rugged compact unit. It has the facility for communication over three independent channels simultaneously. The advantage provides are short on-air time and high network capacity. It has capability to edit, address, transmit, receive, acknowledge, store and print the messages  [23]  . 20. Burst Error Control System for Teleprinter (BEST Mk II). It is a microprocessor based forward error control equipment for reliable burst transmission of alphanumeric messages. It can be easily connected with conventional teleprinters and personal computers to prepare messages off-air from the terminal and transmit synchronously in a burst mode. It has additional features like automatic reception, message numbering, date and time, multiple copy print out, auto print mode, auto repeat facility, etc  [24]  . 21. There are a number of VHF radio sets using burst transmission for data communication; however they are not being discussed further since VHF radio has limited bandwidth and limited range being a line of sight communications. It is thus unsuitable for offensive operation in deserts  [25]  . 22. Deductions. The burst transmission is being used by tactical radio manufactures in USA, Germany, Israel and many other countries due to its advantages like high data transfer, digital encryption, low probability of Intercept and detection. Software Defined Radio and software like Harris RF-3700 Harris Universal Transmission Software not only enable the easy transfer of images/ data but also give the facility to connect to tactical internet network without any additional connections. Thus real time fast and reliable transmission of high resolution digital imagery, motion video clips and other data which is difficult over VHF radio based tactical communication networks can be achieved through burst transmission. The United States is using this technology in their Joint Tactical System Program  [26]  .

Enviromental Influence in Huckleberry Finn :: essays research papers

The environment that someone is in can greatly affect his or her actions, decisions, and way of life. In the novel, The Adventures of Huckleberry Finn, by Mark Twain, Huck is faced with many tough decisions. Huck is a young, white boy, raised in the south. His father is a drunk, and doesn’t teach Huck good morals. As we continue in the book, Huck is faced with the decision, to free a runaway slave, or not. Growing up in the south, he was taught that whites were always better than Negros. But Huck goes against his teachings and continues to help Jim escape to freedom. Huck’s father was an abusive drunk, so legal custody of Huck was switched over to Widow Douglas, who had a slave named Jim. Living with Mrs. Watson, Huck was taught good morals, values, and manners and was forced to go to school. However, he did not live there very long. Huck’s father went on a drunken rampage and kidnapped Huck from Mrs. Watson, and locked him up in his cabin. However, Huck enjoyed living with his father for a while, because he didn’t have to act civilized. Huck eventually figures a way out of the cabin, so he fakes his death so his father doesn’t think he ran away, and then escapes. Huck runs away to Jackson Island, because it is remote and no one lives there. Wandering around the island, Huck runs into Jim, who then explains to him that he ran away because he thought Huck was dead. Jim and Huck converse for a while, till Jim explains that he wants to buy his family back from slavery. Huck then agrees to help Jim escape to freedom by ge tting to Cairo and finding the Ohio River. The time period and location that Huck was living in was very prejudice toward black people. Huck and Jim can only travel down the Mississippi River by raft at night, because Huck fears that people living along the river will think that Jim is a runaway slave and attempt to capture him and turn him into authorities. Huck and Jim have to stop every now and then to pick up necessary supplies, (i.e. food, water, tools) and Huck gets many questions from locals, as to what he’s doing with a black man. The constant questioning annoys Huck and eventually, he reflects on his decision to free Jim. First he writes to Mrs.

Bacons Rebellion Essay -- essays research papers

Bacon's Rebellion "Where we do well know that all our causes will be impartially heard and equally justice administered to all men," as stated by, Nathaniel Bacon. 1 In 1676 an uprising known as Bacon's Rebellion occurred in Virginia. The immediate cause of this revolt was the dissension between the planters and the Indians. Because Sir William Berkeley, the Governor of Virginia had willingly denied support to the farmers, Bacon assumed leadership of an unauthorized expedition against the Indians. When Bacon learned that Governor Berkeley was rising a force against him, he turned away from the Indians to fight with Berkley. This had now become a serious problem for the governor. When news of this revolt had reached King Charles II, it alarmed him so that he dispatched eleven hundred troops to Virginia, recalled his governor, and appointed a commission to determine the causes of the dissatisfaction. Bacon's Rebellion is considered to be the most important event in the establishment of democracy in colonial America because the right to vote and social equality were denied to the farmers by the local government. The right to vote is a small but crucial part of the democracy. During the first half of the 17th century the farmers on the plantations in Virginia were not able to exercise their right to vote. The only people that were able to vote during this time were the wealthy men who owned land. Overall the colonists had not been treate...

Children and Young people Essay

Traditionally the legal the legal age of adulthood was 21 but in the past 20-30 years most jurisdictions have lowered this age to 18. Article 1 of the Convention on the rights of the child (CROC) states that anyone under the age of 18 is child. Also the Children and young person’s (care and protection) Act 1998 (NSW) defines a ‘young person as someone aged between 16-18. These definitions are important because laws treat children and young people differently to adults. Before the late 19th century children committing criminal acts were treated in the same way as adult offenders. The concept of an age before which a person could not be held criminally responsible -doli incapax – did not exist, and children as young as seven were convicted of serious criminal offences. There were two significant events in the 1980s that advanced the rights of children and young people internationally and in common law countries. The two events were the signature of the United Nations Convention on the rights of child (CROC) and the Gillick case. The Convention on the rights of the child (1989) sets out a comprehensive set of rights for all children and young people. These rights cover civil, political, economic, social and cultural rights. The Gillick v West Norfolk and Wisbech Health Authority (1985) was a House of Lords decision. The department of health and Social Security has distributed a flyer advising doctors that they could lawfully provide contraception and advice to persons under 16 years old without parents’ consent. The mother of 5 daughters brought and action against the health authority and the DHSS based on her belief that a child under 16 was too young to make such decision without parental consent. The court of appeal allowed Mrs Gillick’s appeal and took the matter to the House of Lords with affirmed the appeal on the basis that 16 years old was capable of consent in medical matters provided that she has sufficient understanding and intelligence to understand fully what is proposed. In other worlds children have the rights and ability to make decisions to affect their lives and they can do so competently as long as they understand the implications of their decisions Children’s have the right to education and is compulsory for children aged 6-15 to attend school under the Education Act 1990(NSW) Under section 22 of this Act, parents must send their children to a government or non-government School registered with the NSW board of studies. There is no minimum legal age limit for young workers according to the office of industrial relations in NSW however if they are under 15 they must receive authorisation from the NSW Department of Education and Training to leave school. Young people in workplace are covered by all the relevant workplace and safety legislation for workers in NSW. The High Court of Australia followed the decision in the Gillick case and stated that once a person has sufficient maturity and intelligence to understand what is proposed she or he is capable of consenting to medical treatment. Parents have the responsibility to seek proper medical cared for their children even if they have religious objections. The children and Young Persons (Care and protection) Act 1998 (NSW) section 174 authorise a medical Practitioner to carry out emergency treatment on a child or young persons without parental consents. Young people do not have the right to leave their parents’ home before 18 however the law would not normally force young people over 16 to stay at home against their wishes. Children and young people are protected from discrimination on the basis of age by the Anti- Discrimination Act 1977 (NSW). This act also outlaws discrimination on the basis of sex, race, and sexuality. The Convention of the rights of the child (CROC) is a legal mechanism which has been important in putting the rights of children on the global agenda. Once a nation has signed and ratified a treaty the United Nations committee structure monitors and reports on the extent to which hat nation is complying with its international obligation, the committee’s limitation is that it has no coercive powers. Another legal mechanism is the children’s court. Across NSW there are 13 children’s magistrates siting in seven specialists children’s court there also five children’s registrar appointed under the children’s court Act 1998(NSW) to assist in administration of matters before the court. Trade unions are organisations of workers who act together to maintain their rights to good working condition. The Australian council of trade unions (ACTU) provides information about pay and conditions, health and safety issues, apprentice- ships and training and negotiating employment contracts for young people entering the workforce for the first time. Trade unions are a Non-Legal mechanism for protecting rights of children and young people. The kids Helpline are just one of the many organisations from which children and young people in crisis can seek advice. It is a non-legal mechanism just like trade unions. It offers 24hr free telephone and online counselling. If children and young people come into contact with the criminal justice system, it usually through interaction with a police officer when being arrested or questions about some matter. Seventy eight per cent of the 843 children and young people surveyed said that the police rarely treated young people with sufficient respect. It could be argued that children and young people l on the whole do not have good relationship with the police. Young people are frequently targeted for police intervention for lacking respect or simply for being young and out in the public. Children around the world are exploited and abused where the laws of their countries fail to offer protections to them. There are approximately 250 million child labourers worldwide. In 2007 it was estimated there were as many as 300 000 children and young people involved in armed conflict with up to 100000 of these believed to be in Africa. In countries ravaged by war and famine children lack the protection normally afforded to them within the family. Very recently in Australia children sat in immigration detention centres having broken no laws, as a result of the previous federal governments’ punitive laws relating to asylum seekers. In other countries minors are still being executed for the crimes they have committed The rights on children have come a long way. Australian legislation has established processes and institutions to recognise and protect the important role that children and young people play in out in our society. There is still cause for great concern about the exploitation and abuse of children internationally. The force of international law relies on the domestic measures taken to implement the rights contained in treaties such CROC and the pressure brought to bear by parties not only by treaty based human right committees.

Summer vs Winter

Summer Vs Winter My two favorite seasons are exactly six months apart. Of the four seasons, winter and summer are the most excellent; they incorporate the best of both worlds. Some people like winter because of the snow and Christmas, but my favorite is summer because of the warm weather. These two seasons have some bizarre similarities; for example, summer and winter both occur when the Earth is tilted into the Sun. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa.Although winter is a very hectic and stressful season, it’s great to get together with family and friends and enjoy the spirit of the season. In the summer, I can also visit those same family and friends and enjoy activities appropriate to the weather. Each season blesses us with a major break from school; this break is incredibly important because without that relief, students can easily get burnt out of school and become too tired to do decent work and get good grades.Both breaks allow me to unwind and take it easy from the brutal punishments teachers hand down throughout each school year. The time off from school severs as a time for me to take up new opportunities as well. Winter and summer have particular sports for each season, utilizing the weather in each to make the most of recreation. Every six months is a blast because of these amazing seasons. On the contrary, the first big difference between summer and winter is the most obvious one: the weather.In the summer time, it is usually warm and sunny and pleasurable to be outside. I can go swimming, go to the beach, sun bathe, go boating, and all of those fun summer activities everyone looks forward to. In the wintertime, most people think of coldness, but I can still find opportunities to have excitement. The activities are very different; in the winter, I can go ice skating, sledding, and skiing. In the snowy weather I hear a lot about car accidents due to the messy conditions, but i n the summer there are far fewer instances.While summer’s warmth is popular with everyone, many people hate winter because it is so chilly and miserable. The bitter temperatures and weather can greatly affect people’s moods and emotional habits; this is called seasonal depression. It’s the time of year when people are reporting feeling depressed because of the dark, arctic winter months. These feelings can even make winter break dreadful. Summer break, on the hand isn’t affected by the winter blizzards and is three times as long.I can enjoy an enormous amount of free time and do, within reason whatever I want. In the wintertime everyone is flustered and chaotic over Christmas, shopping, and traveling to see relatives. Summer, on the other hand, is a very lazy, relaxed, and enjoyable season. Because of the inconvenience of bad weather, there sometimes are family conflicts when scheduling the holidays. Both seasons clearly have their differences but these d ifferences still make each year unforgettable.
