Humans and Tails :: Anatomy Persuasive Argumentative Essays

Humans and Tails When studying the anatomy of humans in biology textbooks, many authors marvel over the complexity of the human body. Attributes such as our opposable thumbs, bipedal mobility, and cognitive abilities are extolled; however, humans are at a serious disadvantage. We lack major appendages that would aid in daily living; they could greatly improve quality of life. One such appendage is a tail; understandably, some humans have grown accustomed to their current mode of living and would shy away from any change despite its advantages. For this reason, the tail that I am about to depict is prosthetic, allowing for attachment and removal when desired. A tail would give a human numerous advantages, as long as it is constructed in such a way to allow for several functions. With the proper appendage on the distal end, it could perform as a third arm, a temporary seat, or simply an aesthetic addition. All of these functions will be explained in further detail later. In order to create a tail that is as dexterous as possible, it may be useful to study the tails of several different animals and reptiles to determine what the best structure would be. Many primates have prehensile, or grasping, tails. These are comprised of articulated linkages; they cannot rotate in all directions, preventing potential flexibility. Flexor and extensor muscles act as both the driving â€Å"motor† of the tail, and attached bones serve as a support system. Another tail type is similar to an elephant’s trunk; no bone is involved in the structure. Movement is achieved through muscle contraction, and a sheath that is similar to the composition of a tendon prevents shrinkage in the overall â€Å"tail.† Sharks demonstrate a third tail type that is very unique in structure, allowing for exceptional movement. Muscles are arranged around the vertebrae in a conical formation and are attached by three-dimensional tendons. Contraction of these muscles creates a motion that is fluid, and the tail is capable of movement in all directions. In 1994, Kevin C. Zippel, a student zoologist at Cornell University made a surprising discovery. While studying in Papua New Guinea, specifically on the island of Bougainville, he found that a remarkable lizard known as the Solomon Island skink somehow evolved a very unique tail.

A Proposal to End Alcoholism Essay -- Alcohol Addiction Alcoholism Ess

A Proposal to End Alcoholism   Ã‚  Ã‚  Ã‚  Ã‚  In today's day and age, people are beginning to have more and more problems with things that barely even impacted on our world many years ago. Sometimes, however, people don?t even realize that they have a problem and are disturbing not only other people, but also themselves. Alcoholic beverages have slowly wedged themselves into today's society as something that is causing many people problems and drama in their lives. A problem like alcoholism is something that should, and can be, stopped and controlled. With today's modernization and rapid increase of knowledge of medicine and the human body, I have created an idea that could possibly stop the problem of drinking, and the addiction that it creates.   Ã‚  Ã‚  Ã‚  Ã‚  Alcohol is considered a drug for multiple reasons. People, when under the influence, can get either very angry, or are all-around happy people. However, it usually unfolds in the event that when they become happy drunks, they become very grumpy and mean people when they are sober, usually looking for getting more alcohol. Alcohol also ruins people?s bodies, especially their liver. It can impact their body so much that it sometimes brings them to death. People also make very un-educated decisions when they are drinking, and sometimes even when they are sober. When people are under the influence of alcohol, they make bad decisions like driving, even though they can?t see straight, becoming loud, and sometimes even too rowdy. However, ev...

”Heritage” by Countee Cullen Essay

This poem is titled â€Å"Heritage† and is by Countee Cullen (for Harold Jackman). The social issue that motivated Cullen to write Heritage is the oppression that blacks faced and their eagerness to go back to the place that their ancestors were taken from. In the poem Cullen reflects the urge to reclaim the African arts, during this time, the Harlem Renaissance, blacks called this movement negritude. Cullen depicts the negro speaking on the view of Africa, by the all negroes. In the poem, Cullen uses auditory imagery, organic imagery, and visual imagery. Cullen uses auditory imagery to draw his readers in to hear what he hears. The meaning of this poem is to take the reader on a journey of what the negro felt about Africa. Line 12-30, the negro explains that he hears large animals all about and how he can hear the birds of the sky sing. He also explains the sounds of drums that he can hear. Drums in Africa were used for one or two reasons, either celebrations or during war time. This literary device was effective because Cullen captivated what the negro would have heard had he been in Africa. Then Cullen uses organic imagery to draw his readers in to feel what he felt. The usage of this literary device was to show the reader what the negro was feeling when Africa was the thought. In line 22-30, the Cullen uses many metaphors that all tie and have a connection. For example, â€Å"So I lie, fount of pride, dear distress and joy allied, is my somber flash and skin, with the dark blood damned within like great pulsing tides of wine that, I fear, must burst the fine channels of the chaffing net.† Blood from within refers to the negro not being able to change himself from being black. The metaphor is relating wine to blood, pulsing tides to veins, and chaffing net to the heart. Lastly, Cullen uses visual imagery draws the readers in to visually see what the negro sees when he thinks about Africa. Cullen uses this literary device effectively because the reader is able to connect with the negro when thinking about Africa. First, Cullen opens with an unanswered question. Then in lines 1-10, Cullen begins to help us visualize what Africa looks like  through the eye of the negro. He goes to the scenery of Africa by referring to it as the copper sun and scarlet sea. In this allusion, he is describing the reflection of the sun on the water. The negro also spoke about the people of Africa. â€Å"Strong bronzed men, or regal black women from whose loins I sprang when the birds of Eden sang.† Women from whose loins I sprang, he’s talking about the queens of Africa. Strong bronzed men referred to the men who looked like himself during this time, and â€Å"†¦one three centuries removed,† referred to the slave trade. The negro definitely take s the reader on tour of Africa to see, hear and feel everything that he did. In conclusion, the poem was used as a key to unlock some of the thoughts the negro had concerning Africa. The negro in this poem was a representative of all negroes during this time; their thoughts and the their feelings toward Africa. Cullen’s usage of the literary devices allow for an effective expression of the meaning of this poem. Poems are intensified language of experience, so the devices assured the connection of the reader to the poem and the experience. This applies to many issues in society today because as beautiful as our country is there are still dark clouds that cover the very essence of what the states once stood for.

Big Brothers, Big Sisters Essay

Big Brothers, Big Sisters is a prevention program, which enhances the socialization of children through paying attention to their psychological and physical development and increasing their feeling of â€Å"being included† into community and school environment. Due to the fact that the project is mostly directed to planning interesting leisure and education-related activities for minors, it can be interpreted as prevention program, as it creates a friendly and harmonious environment which encourages and reinforces the child’s self-esteem through establishing a symmetric communication between the minor and adult and teaching important social skills. As for me, I believe that the program is effective, as it deals mostly with three important predictors of deviance and crime – absence of developing and diversified pastime, lack of engagement with community activities and academic failure (and the consequent loss of interest in education) in schoolchildren. In addition, the relevant study, provided by the website, demonstrates the following results: â€Å"Researchers found that after 18 months of spending time with their Bigs, the Little Brothers and Little Sisters were: – 46% less likely to begin using illegal drugs; – 27% less likely to begin using alcohol; – 52% less likely to skip school; – 37% less likely to skip a class; – more confident of their performance in schoolwork; – one-third less likely to hit someone† (at http://www. bigbrooc. org/html/our_impact. html, 2007). There are three major curriculums, designed within the program. First of all, there is a set of community-based activities, which take place once a month. The community volunteers encourage the participants to do sports, play intellectual games, have meals together or simply take walks in the park. Group-based mentoring program includes monthly meeting of Big and Little Brothers and Sisters and learning new and unusual types of sports, associated with team playing. For instance, the participants do kayaking, play miniature golf or team bowling. All these sports are aimed at improving the children’s concentration, dexterity, ability to plan and make joint decision within the team; as one knows from developmental psychology, the progress of physical skills is particularly sensitive to influences at teen age, when the person is actively growing. The complex of school-based activities comprises weekly sessions, during which the minors are assisted in their home assignments. The major advantage of this program, which actually can cause in the jealousy of the similar agencies, is its image of partnership between adults and children, who receive not mentors, but friends, whose role models are more likely to be learned by minors. The typical agencies of this profile (working in the directions of prevention and diversion) more willingly involve competent specialists (in a limited number) than volunteers, so the underage target audience not always receives socialization experience and learn social skills during workshops and training. In addition, the Big Brothers Big Sisters project manages to maintain its focus on the underage audience in all points of its curriculum and stimulates the natural and healthy socialization in minors (through communication and team activities), instead of creating artificial conditions (like those in workshops and purposeful social skills training). The goals of the Big Brothers, Big Sisters project to great extent coincide with the orientation of the whole juvenile justice system. The major priority of the system is prevention of juvenile crimes and recidivism, but this goal is traditionally accomplished through enlightenment and education in the spheres of crime and punishment, drug addiction and alcohol use. The efforts of the program, on the other hand, are directed to improving the minors’ physical and psychological health and helping them establish friendly contact with the environment. This model is often neglected by the juvenile justice system, so it would be beneficial to introduce the program under the management of the network of government institutions, responsible for delinquency prevention, as the idea of healthy and natural socialization is likely to become a new direction in the functioning of the juvenile justice system and the unity of accountability will provide courts will more comprehensive information about the children. In addition, the program will also demonstrate success in the field of diversion. Finally, the program will correct the official and formalized image of the juvenile justice system and break the stereotype of the â€Å"punishing institution†. The major strength of the program is its positivist approach to prevention, which includes strengthening the minors’ social and psychological potential rather than intimidating schoolchildren about the adversities, associated with delinquency and illicit drug use. The project embraces community work, group work and school work, so that the major environments, in which the children operate, are influenced and to some extent altered. The ultimate goal in this sense is the development of the sense of inclusion into all these environments in the participants. On the other hand, the program lacks one important components, which is family-based work. As the website suggests, the underage participants originate from the households, where domestic violence and alcohol use are practiced. With respect to the fact that behavior models, learned in the family, are to certain degree determinative in teenagers’ behavior, it would also be useful to establish a contact between the families and the community and arrange activities, which imply the creation of a large team, consisting of children, their parents and the Bigs. Another weakness is the lack of basic psychological education for children, as at the certain stage of their development they need theoretical knowledge of building relationships and understanding others, so the Big Brothers, Big Sisters can introduce monthly discussions of the achievements and difficulties, experienced by the participants in their relationships with coevals and adults.

The effects of Information and Communication Technologies Essay

In the last few years India has made rapid strides as a developing nation. Education has played a key role in that. Educational institutions, which lay down the foundation for learning and understanding, have reached out to the corners of the country. The purpose of this paper aims to bring together the findings and key points from a review of significant part of the available literature associated with ICTs for Education and ICTs in Education. This review set out to identify and evaluate relevant strategies in national and international research and initiatives related to measuring and demonstrating the effective use of ICT for education. Schools, colleges, IIMs, IITs and other professional institutions are no longer confined to the metros but are reaching out to the fringe areas as well. What has been critical in this regard is that not only the sources of education have increased, but the manner in which knowledge is imparted has also gone a sea change, courtesy the information an d communication technology. Summary: Information and communication technologies (ICT) have become commonplace entities in all aspects of life. The use of ICT in education lends itself to more student-centred learning settings. Effective use of ICT for Education, along with ICT use in the teaching learning process, quality and accessibility of education, learning motivation is shown in this paper. The introduction of the term ‘ICT’ (information and communication technology) around 1992, when e-mail started to become available to the general public (Pelgrum, W.J., Law, N., 2003). The concept of mobile learning was emerged about a decade ago and got recognition as a new research field. Many countries now regard understanding ICT and mastering the basic skills and concepts of ICT as part of the core of education, alongside reading, writing and numeracy. The world moving rapidly into digital media and information, the role of ICT in education is becoming more and more important and this importance will continue to grow and develop in the 21st century. According to a United Nations report (1999) ICTs cover Internet service provision, telecommunications equipment and services, information technology  equipment and services, media and broadcasting, libraries and documentation centres, commercial information providers, network-based information services and other related information and communication activities. According to UNESCO (2002) information and communication technology (ICT) may be regarded as the combination of ‘Informatics technology’ with other related technology, specifically communication technology. The 1990s was the decade of computer communications and information. ICTs for education refers to the development of information and communications technology specifically for teaching/learning purposes, while the ICTs in education involves the adoption of general components of information and communication technologies in the teaching learning process. ICT enhancing teaching and learning process: The field of education has been affected by ICTs, which have undoubtedly affected teaching, learning and research (Yusuf, 2005). Teachers generate meaningful and engaging learning experiences for their students, strategically using ICT to enhance learning. ICT enhancing the quality and accessibility of education: ICT increases the flexibility of delivery of education so that learners can access knowledge anytime and from anywhere. ICT enhancing learning Environment: ICT presents an entirely new learning environment for students, thus requiring a different skill set to be successful. ICT enhancing learning motivation: ICTs can enhance the quality of education in several ways, by increasing learner motivation and engagement, by facilitating the acquisition of basic skills, and by enhancing teacher training. ICT enhancing the scholastic performance: Based on the extensive usage of ICTs in education the need appeared to unravel the myth that surrounds the use of information and communication technology (ICT) as an aid to teaching and learning, and the impact it has on students’ academic performance. Scope of Mobile Learning: Information and Communication Technology is playing a vital role to shaping the learning method, by providing better resources to learn remotely. Mobile technology was presented in 1990s and become the most popular way of communication. Mobile learning facilitates learners to move effortlessly over varied positions and to connect up learning in different localities. CONCLUSION: Education has become one of the most important issues not only for the individuals but for organizations and governments around the world. Since the world is changing rapidly with the advancement in technology informal ways of learning are also required for that purpose. ICTs for education refers to the development of information and communications technology specifically for teaching/learning purposes, while the ICTs in education involves the adoption of general components of information and communication technologies in the teaching learning process. This literature review has sought to explore the role of ICT in education as we progress into the 21st century. Mobile enabled technology has played an important role to build and implement new solutions for informal learning. The adoption and use of ICTs in education have a positive impact on teaching, learning, and research. The overall literature suggests that successful ICT integration in education.
