Introduction to Human Development Essay Example Introduction to Human Development Essay Introduction to Human Development Essay INTRODUCTION â€Å"The human being†¦ the most sophisticated, amazing and wondrous creation in this earth. If one would take a peek at what’s inside his human body, he’ll be amazed to see hundreds of bones, miles of blood vessels and trillions of cells, all working together so he could be healthy and in perfect shape. Each organ, each body part, each a miracle†¦ Each a piece of evidence of God’s mighty providence. † This lesson familiarizes you with the principles and stages of human growth, maturation and development. It discusses how humans grow, develop, change and adapt to their environment throughout their life span. Warm-Up Did you know that there are 26 billion cells in a new born baby and about 50 trillion cells in an adult? Cells are responsible for supplying you with the energy you need, transporting oxygen around your body and moving your body parts. Indeed, every single cell in your body helps you maintain vitality and life. BASIC CONCEPTS 1. Human Development refers to the biological and psychological development of the human being throughout the lifespan. It consists of the development from infancy, childhood, and adolescence, adulthood to old age. . Development refers to the qualitative, progressive series of changes in an orderly and coherent fashion leading to maturation 3. Growth refers to quantitative changes in an individual as he progresses in chronological age. 4. Maturation is the process by which heredity exerts its influence long after birth. 5. Genetics is the science of heredity. It originated with the discovery by Gregor Mendel that hereditary characters are determined by f actors transmitted without change and in predictable fashion from one generation to the next. 6. Heredity is the passing on of physical or mental characteristics from parents to offspring through the genes. 7. Gene is a unit of heredity; a segment of the DNA which contains the instructions for the development of a particular inherited characteristic. There are about 30,000 genes that contain chemical instructions. The chemical instructions in the genes program the development of millions of individual parts into a complex body and brain. 8. DNA or deoxyribonucleic acid is a nucleic acid which occurs in combination with protein in the chromosomes, which contains the genetic instructions. It consists of four nitrogenous bases (adenine, guanine, thymine, cytosine), a sugar (2-deoxy-D- ribose), and phosphoric acid, arranged in a regular structure- (two chains twisted round each other in the form of a double helix). 9. Nucleic acids are large molecules produced by living cells which store genetic information, and composed of a chain of nucleotides. Two forms are: deoxyribonucleic acid (DNA) which is found primarily in the nucleus and ribonucleic acid (RNA), found in the nucleus and cytoplasm. 10. Chromosomes are threads within the nucleus of a cell which are the carriers of genetic material, consisting of DNA and various types of protein (histones). They occur in pairs a normal human body cell has 46 chromosomes: 22 pairs of autosomes together with one matching pair of X chromosomes in females (the 23rd pair- XX) and one mismatching pair, the X and Y sex chromosomes in males (the 23rd pair-XY) 11. Sex chromosome is the 23rd pair of chromosomes represented differently in the sexes, and responsible for the genetic determination of the sex of an individual. There are 1,000 genes in each chromosome. 12. Gamete is a specialized reproductive cell that fuses with another gamete of the opposite sex during fertilization, to form a zygote. Gametes are usually differentiated into male (sperm) and female (egg, ovum). 13. Sexual Reproduction is the act or process of producing offspring through sexual intercourse or artificial insemination. The Stages of Reproduction: 1. During ovulation period, females release and deposit sex chromosomes in the uterus. In the reproduction process, the male releases sperm cells that contain either X or Y chromosomes. The first male chromosome that meets and unites with the egg determines the gender of the offspring. If Y chromosome from the male first unites with the egg (which is an X chromosome), the offspring is male (XY). But if an X chromosome coming from the male first unites (XX), the gender of the offspring is female. 2. The successful sperm cell penetrates inside the ovum. The tail of the sperm separates to the head during this process. The nucleus of the sperm cell will then unite with the nucleus of the ovum and undergo a process called fertilization. The 23 chromosomes from the sperm cell will pair with the 23 chromosomes from the egg cell and the resulting zygote starts life with 46 chromosomes. . When the zygote is about to divide, chromosome replication and cell division arise wherein chromosomes and genes are doubled. All cells except the reproductive cells receive identical inheritance. The process of cell division continues with the chromosomes being always replicated as described. 4. Sometimes, instead of remaining together as parts of a single organism, the cells separate. Th ey develop to form identical twins. Siamese twins come from an incomplete separation of the two identical cells. 5. However, if two egg cells are fertilized separately, they develop to form fraternal twins. Chromosomal Abnormalities: 1. Turner’s syndrome- is a rare case wherein females may be born with only 1 X chromosome (45 chromosomes instead of 46). They fail to develop sexually at puberty. They show normal intelligence but with cognitive defects like poor performance in math and spatial organization. 2. Down’s Syndrome- a defect which usually stems from a failure of one chromosome of a germ cell to split in the normal way to form a healthy ovum with 23 chromosomes; an ovum with 24 chromosomes is produced, and if this ovum is fertilized, the developing embryo possesses an extra chromosome (47). The condition is named after English physician J L H Down (1828-96), and is sometimes referred to as mongolism. 3. Klinefelter’s Syndrome- a rare case wherein the 23rd chromosome fails to divide properly giving off extra X or Y chromosome (47). An individual with an xxy 23rd chromosome is physically a male but with feminine characteristics like large breasts but with small testes incapable of producing sperms. Male with XYY chromosomes are taller and unusually aggressive than the normal XY. Sex-Linked Genes 1. Sex-Linked Genes bare genes carried on the X and Y chromosomes, and the characteristics they control. In mammals females have two X chromosomes and males an X and a Y chromosome. Women transmit one X chromosome to either sons or daughters, while men pass their X chromosome only to their daughters. a. A characteristic feature of sex-linked inheritance is thus the absence of male-to-male transmission. Most sex-linked diseases in humans are inherited as recessives; with the males the affected sex (e. g. colorblindness, baldness, hemophilia, Duchenne muscular dystrophy). 2. Hemophilia is an inherited disorder of blood coagulation, resulting from a deficiency in one of the proteins responsible for normal blood clotting. STAGES OF HUMAN DEVELOPMENT STAGESAGEHIGHLIGHTS 1. Prenatal Conception to birth Rapid physical development of body and nervous system 2. Infancy Birth to 2 years Motor development. Attachment to primary caregiver. 3. Childhood 2 to 12 years Increasing ability to think logically and reason abstractly. Refinement of motor skills. Peer socialization. 4. Adolescence 13 to 20 years Thinking and reasoning are more mature like. Identity crisis. Socializations to opposite sex. STAGESAGEHIGHLIGHTS 5. Adulthood 21 to 60 years Love, marriage, career and stability. . Old Age 61 to retirement Reflection of accomplishments. Physical and mental health deteriorates. A. Prenatal Stage 1. Prenatal Period- the period from conception to birth, usually encompassing nine months of pregnancy. 2. Pregnancy is a physiological process in which females nurture their developing young within the uterus; also known as gestation. It begins when the fertilized ovum embeds itself in the uterine wall (implantation), and ends with the birth of the offspring (parturition). It lasts on average 38 weeks (9 ? onths or 266 days) from the first day of the last menstrual period, menstruation is absent (in response to circulating hormones), the uterus enlarges, the breasts increase in size in preparation for lactation, and there are other major physiological changes. 3. Fertilization is the union of two gametes to form a zygote, as occurs during sexual reproduction. 4. Zygote a one-celled organism formed by the union of a sperm and egg cell. The zygote undergoes rapid mitotic divisions with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo. . Cleavage is the process by which a fertilized egg cell (zygote) divides to give rise to all the cells of an organism. The prenatal stages 1. Germinal stage the first prenatal stage that occurs from first to second week of conception. 2. Embryonic stage the second prenatal stage that occurs fr om third to eighth week of conception. 3. Fetal stage the third and final prenatal stage that occurs from ninth week of conception to birth.

B. INFANCY. 1. Infancy is the period of human development from birth to two years. 2. Neonate is a newborn child. 3. Capacities of a newborn: a. Newborns have poor vision and cannot see as well as an adult until about age 2. b. Newborns pay attention to sounds particularly to human speech. c. Infants can discriminate different tastes and prefer sweets like breast milk. d. Neonate can identify odors especially that of the mother. e. Infants can learn from the moment they are born and show good memories by 3 months of age. 4. Motor Development refers to the progression of muscular coordination required for physical activities.

Critical Periods are the crucial time periods in a person’s life during which specific events occur if development is to proceed normally. In fetus, t he 6 to 7 weeks is critical for normal development of the sex organs- like deficiency in hormones. Visual corrections are critical up to 7 years old. . Sensitive Periods are periods that are optimal for a particular kind of development. First year of life is a sensitive period for interpersonal attachment. 7. Temperament refers to such mood-related personality characteristics. a. Easy Temperament is a term used to describe a child who is playful, regular in his sleeping and eating patterns, and adapts readily to new situations. b. Difficult Temperament is a term used to describe a child who is irritable, has irregular sleeping and eating patterns, and responds intensely and negatively to new situations. c. Slow to warm up temperament is a term used to describe a child who is relatively inactive, tends to withdraw from new situations in a mild way, and requires more time than easy infants to new situations. 8. Attachment is used to describe an infant’s tendency to seek closeness to particular people (especially the mother) and to feel more secure in their presence. 9. Separation anxiety is a distress among infants when a caretaker is not nearby. 10. Sensitive Responsiveness is a characteristic of a caretaker who responds promptly when the baby cries and behaves affectionately when they pick up the baby. The caretaker also tailors their response to the baby’s needs. C. ADOLESCENCE 1. Adolescence refers to the period of transition from childhood to adulthood covering 13 to 20 years old. It is characterize by a rapid physical growth known as the adolescent growth spurt. 2. Puberty is a period of sexual maturation that transforms a child into a biologically mature adult capable of sexual reproduction, which takes place over a period of 3 or 4 years. a. It starts when a female has a menarche between the ages of 11 to 17 (average is 12) and when a male begin to ejaculate semen between the ages of 12 to 16 (average is 14 1/2). . Secondary sex characteristics like bodily hair patterns, pitch of voice and muscle development are evident for both males and females. c. Changes in the intellectual abilities, body proportions, and sexual urges (together with changing relationships with parents and peers) create enormous challenges. d. Psychological effects of puberty such as moodiness, inn er turmoil, and rebellion are linked directly to the hormonal changes of puberty. D. ADULTHOOD 1. Adulthood is a stage of human development from ages 21 to 60 that is marked by both maturity and change. . It involves transition in the family relationships, including adjusting to marriage parenthood and empty nest. 2. Age-related physical transitions include: changes in appearance; sensory losses (especially vision and hearing), and hormonal changes. Mental speed declines. a. Menopause is the cessation of menstruation that usually occurs between 45 and 50 years. It is often accompanied by physical (sweating, hot flushes, vaginitis) and psychogenic (depression, insomnia, fatigue) disturbances, which generally respond to estrogen therapy. . Mid-life Crisis is a difficult, turbulent period of doubts and reappraisal of one’s life. E. OLD AGE 1. Old age a stage of human development which covers those 65 years old and above. 2. Ageism is discrimination on the basis of age, often res ulting in the denial of rights and services in the elderly. a.

Alzheimer’s disease is a degenerative disorder whose progression cannot be stopped; it is irreversible and ultimately ends in death.

Reporting Money to Customs at the Canadian Border

Reporting Money to Customs at the Canadian Border When traveling to and from Canada, there are rules surrounding what youre allowed to bring into and out of the country. Canadians returning home must declare any goods they purchased or otherwise acquired while out of the country. This includes things like gifts, prizes, and awards, including items that will be shipped later. Anything purchased at a Canadian or foreign duty-free shop also must be declared.   A good rule of thumb when returning to Canada through customs: If youre not sure whether or not  something needs to be declared, its better to declare it and clear it with border personnel. It would be much worse to fail to declare something that officers discover later. Officials can seize any goods being illegally imported into Canada and, if  caught, youre likely to face penalties and fines. If you try to bring a firearm or other weapon into Canada without declaring it, you could face criminal charges. Bringing Money Into Canada There are no limits to the amount of money that travelers may bring into or take out of Canada. However, amounts of $10,000 or more must be reported to customs officials at the Canadian border.  Anyone who fails to report amounts of $10,000 or more could find their funds seized, and face a penalty between  $250 and $500. If you are carrying $10,000 or more in coins, domestic and foreign bank notes, securities such as travelers checks, stocks, and bonds, you must complete a Cross-Border Currency or Monetary Instruments Report - Individual Form E677. If the money is not your own, you should complete Form E667 Cross-Border Currency or Monetary Instruments Report - General. The form should be signed and handed to a customs officer for review. Completed forms are sent to the Financial Transactions and Reports Analysis Center of Canada (FINTRAC) for assessment and analysis. Non-Canadians Visiting Canada Anyone bringing goods into Canada must declare them to a border officer. This rule applies to cash and other items of monetary value. Its a good idea to have some idea of exchange rates because the minimum amount required to be declared is $10,000 in Canadian dollars. Personal Exemptions for Returning Canadians Canadian residents or temporary residents returning to Canada from a trip outside the country and former Canadian residents returning to live in Canada may qualify for personal exemptions. This allows them to bring a certain value of goods into Canada without having to pay the regular duties. Theyll still have to pay duties, taxes and any provincial/territory assessments on the value of goods above the personal exemption. Future Issues at the Border The Canada Border Services Agency keeps a record of violations. Travelers into and out of Canada who develop a record of infractions may have issues crossing the border in the future and may be subject to more detailed examinations. Tip: The best course of action for anyone entering Canada, whether youre a citizen or not, is to have your identification and travel documents readily available.   Be honest and be patient, and youll be on your way quickly.

Interview Assignment on Nursing Example | Topics and Well Written Essays - 2000 words

Interview on Nursing - Assignment Example Two nurse managers were interviewed for this purpose. The interviews showed that the main challenges faced by managers are shortage of trained staff, inadequate training opportunities, lack of motivation, budget constraints and lack of team spirit. Detailed analysis of the interviews revealed that the experienced managers face more issues related to budget, maintaining the standard of patient delivery and implementing ethical code of conduct while dealing with patients while the relatively inexperienced managers face challenges like problem solving, authority issues and lack of efficient communication. 1. INTRODUCTION A nurse manager is responsible for conducting nursing programs in a large unit of a hospital; management related responsibilities of a nurse manager include: assisting in hiring employees, helping them in problem solving and goal setting, supervising the nursing quality in general, arranging for the training of personnel who need it and keeping a record of budget and su pplies/equipment etc (Health care position study, 1990). According to Hirschfeld (1992), the first challenge faced by nurse managers is lack of synchronization of theory and practice, thought nurses are educated and apparently trained, but most of them come with practical experience that is not adequate; secondly, a general lack of sharing the care giving responsibility among nurses is also a challenge for nurse managers; thirdly, managers face issues due to the lack of nurses familiarity with different cultures and inability to deal with cultural diversity in hospitals. A study by Tourish and Mulholland (1997) revealed that within NHS there are many communication barriers among the nurses and their managers. The study further reported that experienced managers seem to have less communication issues as compared to the relatively inexperienced or newly hired/promoted managers. Another study by Mathena (2002) attempted to identify the challenges faced by nurse managers. The researcher reported that the main challenge faced by nurse managers is that they are often required to assume roles beyond their education and prescribed responsibilities and that in such cases, the leadership skills and styles differ among the experienced and inexperience managers. 2. INTERVIEWS Two nurse managers from different units of a large hospital were purposively selected for interviews. One of the two was having a significant five years experience while the experience of the other interviewee was less than one year. This was done to enable a comparison of the challenges faced by both the mangers. Each interview lasted 15 minutes, and was based on semi structured interview schedule, constructed flexibly to allow for any questions that might help in obtaining more relevant information to the topic. 3. SUMMARY OF FINDINGS The main findings of the interviews are listed below: The duties of a nurse manager according to the nurse managers include: keeping track of the budget and supplies, assisting the administration in hiring new Personnel, arranging for or providing training of the hired nurses, supervising the general performance of nurses, ensuring and implementing quality patient care delivery programs and problem solving for nurses, counseling them if needed. The main challenges faced by nurse managers include: shortage of trained nurses, lack of adequate training facilities, constrained budget, lack of participation of nurses in patient care awareness programs, de-motivation among nurses due to low salaries and increasing cultural diversity in hospitals. The experienced manager was mainly concerned with issues like nurse motivation and ethical implementation of high quality patient c

Blog - Coursework Example Therefore, current management teams tend to focus on the required combinations that are required in terms of employees for economic and productivity values. When evaluating the effects of team diversity on business performance, (Kochan, et al., 2002, p. 12) indicated that different levels employee sourcing create a very strong case for the diversification of the required returns. The diversity under consideration in this situation includes cultural, demographic, technical and cognitive. After this integration, the group processes will include communication, creativity, conflict and cohesion. The required outcomes in this regard are; reduced turnover rate, satisfaction of all stakeholders and improved performance. It has been noted that diversity, if not well managed have adverse effects on the running of a company. Conflicts and ineffective communication are an inevitable part of life in any group setting. However, these can take a different dimension when dealing with diversity (Her rera, Duncan, Ree, & Williams, 2013, p. 5). Lower levels of cohesion and miscommunication are some of the negative issues that must be looked into before effectiveness of the whole company is upgraded. In fact, the relationship that exists between diversity and performance in any company is dependent on the human resource enforces the good practices of creativity and innovation at the initial levels of hiring employees. Therefore, diversity must be effectively handled if it has to give the best results (Mirza, 2011, p. 4). Effective handling of diversity has several advantages. McDonalds Company is one of the companies that have highly benefitted from the aspect of work place diversity. Increased productivity has been highly seen as a result of the diversity created. The company, a US grocery company has a very wide base in more than 118 countries and in particular commands a very huge market in the UK (Mirza, 2011, p. 7). The use of diversity has made the company create a diverse w ork force with different talents that have highly reduced the turnover rate of the company and in turn increasing its stores all over the world. Another benefit that has come to the company is increased creativity and the rate of solving company problems. Different cultures come with different needs and concerns (Kochan, et al., 2002, p. 13). The company has concentrated so much on diverse work force that it has equally created a diversified customer base based on the cultural range of products sold. So committed to the issue of diversity it is, that the company has created a World Leadership Development. Because of the company external development strategy, it does not discriminate (Mirza, 2011, p. 3). The third advantage as seen in the McDonald’s case is the attraction and retention talent. The company has been seen to highly involve itself in the community based programs where it creates the diversity needed. According to Mirza (2011), the company supports groups of networ ked individuals in the composition of gay and lesbian employees, because these are very important to the company employment cycle. In fact, the company has a Chief World Diversity Officer, Patricia Sowell Harris whose work is to see that the values of these individuals are upheld. According to the company, they are important, not only as a customer base development team but also worthy employees. Tasked with making sure that people deliver their best, she has made sure that the company effectively responds to the aspect of diversified talent. With the inclusion of

Tragic Hero Of Shakespeares Great Tragedies Essay Example for Free

Tragic Hero Of Shakespeares Great Tragedies Essay A tragic hero was defined by Aristotle as one who makes an error of judgment that eventually leads to their own destruction. Aristotle once had said that â€Å"A man doesn’t become a hero until he can see the root of his own downfall.† In William Shakespeare’s Macbeth, the protagonist Macbeth is a true example of a tragic hero as he had countless noble qualities coupled with several tragic flaws. He holds an importance to his society; in the beginning, a fearless nationalist, fighting for his country and then eventually he became king. Macbeth did have some major character flaws such as his great ambition, him being haunted by superstition and he had made many grave errors in judgment, one of them being the murder of the King of Scotland. For the duration of events in the plot, Macbeth progressively becomes more and more miserable. There were outside forces which contributed to his corruption; the main force would be the three witches. A Shakespearean tragic hero contains all or most of the following qualities: providing a moral example to the audience, suffering public embarrassment, and meeting his doom with courage and dignity which Macbeth did all of. With it taken into consideration, Macbeth is most definitely a tragic hero. With Macbeth becoming more important in the plot is one of the crucial reasons to why he became a tragic hero in the end. Macbeth was a Scottish general, who was a fearless man and his performance in Scotland’s battle was celebrated greatly in the beginning of the play. Macbeth’s performance was described by the Captain as â€Å"Cannons overcharged with double cracks, so the doubly redoubled strokes upon the foe† (1.2.41-42) With Macbeth doing so well and receiving such positive feedback, King Duncan couldn’t help but be so overjoyed with Macbeth. With all of the valiant news, Duncan’s only response was to upgrade Macbeth’s title from Thane of Glamis to Thane of Cawdor. â€Å"No more that Thane of Cawdor shall deceive Our bosom interest. Go, pronounce his present death, and with his former title greet Macbeth† (1.2.73-76); â€Å"What he hath lost, noble Macbeth hath won.† (1.2.78). Many of Macbeth’s major character flaws were displayed along with his weaknesses and serious errors in judgment in the duration of the play. After he received all the recognition from his success in battle along with his title being upgraded, the ambition he had to become king couldn’t help but rise. His ambition to become King was too heavy and they overtook his morals in the end after meeting the witches’ and hearing his prophecies. When his ambition was combined with the witches’ prophecies it was as if he no longer had morals since he was easily persuaded into what he’d like to hear. When Macbeth is thinking of murdering Duncan to become King his ambition takes control for a moment, but then his morality takes back over. â€Å"Why do I yield to that suggestion Whose horrid image doth unfix my hair and make my seated heart knock at my ribs against the use of nature?† (1.3.147-150). When Macbeth recognizes that he is opening up to his tempt ation, he begins to question himself as to why. But, he begins to persuade himself into believing that the temptation of committing murder can’t be as daunting as he thinks it is, â€Å"Present fears are less than horrible imaginings† (1.3.150-151). In layman’s term, his only fear is fear itself. Macbeth is portrayed as this brave man, whose wife manipulates him by insulting and accusing him of being cowardice, which he believes he has to prove to be false. He won’t allow a single thing get in the way of his future as king. As soon as Macbeth made his final decision, after changing his mind five times, to kill Duncan; eventually it escalated into a sea of many problems both big and small; this is what brought Macbeth to his tragic end. The roles that played the biggest part in Macbeth’s deteriorating character would have to be the three witches. â€Å"FIRST WITCH: All hail Macbeth! Hail to thee, Thane of Glamis! SECOND WITCH: All hail Macbeth! Hail to thee, Thane of Cawdor! THIRD WITCH: All hail Macbeth, that shalt be king hereafter!\ (1.3.51-53) The witches had no effect on anyone except Macbeth. Macbeth was completely captivated by the witches. If Macbeth had never met the witches or was told his prophecies he would have gone on through a life of no excitement. Due to being told the prophecies his curiosity of how he would be able to become King of Scotland began to grow immensely and the importance he holds for Scotland increases. Macbeth fast-tracked from Thane of Glamis to Thane of Cawdor and eventually reaching what he wanted the most, the title of the almighty King of Scotland. In Act 4, scene 1, the three witches appear to Macbeth again and they conjure three apparitions for him. The first being (appears in 4.1.77) an armed head and told Macbeth to â€Å"Beware Macduff!† (4.1.81). Macbeth’s reaction to the witches after seeing the apparition was simply thank you. However, I already knew to do that. The second apparition (appears in 4.1.88) a bloody child that said to Macbeth that no man born of a woman could ever harm him. After seeing the second apparition Macbeth thought to himself why must I be aware of Macduff? Everyone is born of a woman. The third and final apparition that appeared to Macbeth (appears in 4.1.98) is a crowned child with a tree in his hand which told Macbeth that he must relax and forget about his troubles because â€Å"Macbeth shall never be vanquished be until Great Birnam Wood to high Dunsinane Hill shall come against him.† (4.1.105-107). But Macbeth vetoed it off as a possibility because it seemed completely ri diculous and impossible for a forest to be able to move. However, unbeknownst to Macbeth was that Macduff actually had not been born of a woman. The doctors had to slice her open (cesarean birth) to remove the baby. Macbeth had been tricked by the three witches, due to Macbeth being so confident nothing would ever happen to him because of his prophecies he did not take the necessary precautions to protect his well-being and his title as King. Macbeth was a victim of superstition due to his avid imagination. His superstition is what made it so easy for him to not question the promises that the apparitions made. His superstition is what made him strongly cling to his belief in the promises made even when circumstances became strenuous. His imagination is so strong that when it was left to run uncontrolled his â€Å"function/ Is smother’d in surmise.† As seen in the â€Å"dagger† scene and in the panic Macbeth had suffered after Duncan had been murdered. It was also seen in the scene which Macbeth saw Banquo’s ghost at the banquet. Undoubtedly, Macbeth incarnates the attributes of Aristotle\s tragic hero in many ways. He had become very important to his society and dreamed of being the most powerful ruler. His ruin was led by his overcoming ambition, superstition, and moral cowardice. It led to an ocean of problems from which there was no possible solution to and from that came his inevitable doom. Macbeth started as a nobleman who was hailed as the savior of this country, a â€Å"valiant cousin,† a â€Å"worthy gentlemen,† but changed to a man of unending cruelty. There should be no skepticism about this, Macbeth is indeed a tragic hero.

Technological Literacy :: Technology Technological Papers

Technological Literacy Definitions and Rationale What is technology? A definition of technology literacy might well begin with a definition of technology. Technology consists of all the modifications humans have made in the natural environment for their own purposes (Dugger 2001)—inventions, innovations, and changes intended to meet our wants and needs, to live longer, more productive lives. Such a broad definition of technology includes a broad spectrum of artifacts, ranging from the age-old (flint tools, wheels, levers) to the high-tech (computers, multimedia, biotechnologies). In short, if humans thought of it and made it, it’s technology. Two important points need to made about such a broad definition of technology. First, although some writers address only computer and communications technology (e.g., Selfe 1999), technology is usually defined to include far more than instructional or communications technology (Custer 1999). Computers, e-mail, and Web TV are only one part of the array of devices and procedures we encounter in day-to-day life—everything from digitized kitchen appliances to transportation systems and integrated manufacturing. Second, science and technology, although closely related, are different (Sanders 1999). Science generates knowledge for its own sake, proposing and testing explanations. Technology, on the other hand, develops human-made solutions to real-world problems. Of course, science uses technology to generate knowledge and technology uses scientific knowledge to generate solutions, so the two are integrally connected; but they are different fields driven by different concepts and pr ocesses (Bybee 2000). What is technological literacy? Just as technology involves more than computers and the Internet, technological literacy involves more than hands-on skill in using technology (Bugliarello 2000). Certainly, knowing how to use information technology is increasingly important in our knowledge society, whether we are looking for a job, marketing a service, or shopping for a product. We must also be able to use other devices, like microwaves, copying machines, and self-service gas pumps, that have become part of everyday life at home, at work, or in the community. However, the ability to use technology is only one part of technological literacy. What are the other parts? Interpreting a large body of work on technological literacy from a variety of fields, Gagel (1997) suggested common elements of an enduring, inherent technological literacy that can last through the fast, continuous changes in technology. This type of technological literacy would include knowledge about the details of individual technologies and about the process of technology development. It would also include a holistic understanding of the historical and cultural context of technology and adaptability based on initiative and resourceful thinking.

The Yellow Wallpaper Analysis

The Yellow Wallpaper Analysis As I started reading this short story, it clearly introduced who the characters are and where it took place. The narrator is a woman; she has no name, remains anonymous throughout the story. She lives with her husband John in a house. This house is isolated from society, since the short story indicates that it is far from village, roads or any means of communication. It also contains locks and gates throughout. The woman is ill and this illness has placed her in a weak position with her husband and everything around her.We know that she likes to write, but her husband doesn’t let her, so she does it in secret. Although this type of writing is mainly to show mild personality disorder in dealing with life, at the same time I believe it shows how each person expresses their illness and how it builds up with certain outcome. Here the author shows how the woman expresses her illness through the circumstances of the yellow wallpaper such as dreaming and fantasying through the paper, which led to her breakdown. At first, the narrator describes the yellow wallpaper as ?It is dull enough to confuse the eye in following, pronounced enough to constantly irritate and provoke study, and when you follow the lame uncertain curves for a little distance they suddenly commit suicide–plunge off at outrageous angles, destroy themselves in unheard of contradictions  .? It shows how the narrator dislikes the yellow wallpaper and she elaborates her feelings towards it. This quote explains a lot about how she feels, and also points out how suppressed and weak she is. When it said ? follow the lame uncertain curves? t refers to the husband that may lead the narrator to commit suicide because of the way she listens and obeys him. Although he seems to say the things that would make her better and assure her that she is getting better, he is not really letting her do what would make her better, which is what she wants. As a physician who recog nizes and treats his wife’s condition, it would appear to be that he understands her best, but he does not seem to realize how severe her state is. Neither does he have an adequate way of treating it, like not letting her do what she wants like for instance writing.I believe he underestimates the state of her mind, and he has a lot to do with the outcome of her condition. This leads to her obsession with the wallpaper. At first the narrator hated it, and then she got used to it. She started letting her imagination wander about this wallpaper, she saw in her mind's eye people, scenes: ? there is a beautiful shaded lane that runs down there from the house. I always fancy I see people walking in these numerous paths and arbors, but John has cautioned me not to give way to fancy at least.?By focusing on these fantasies or dreams, I believe it expresses her feelings and makes her more confident. Despite what John thinks about her fantasies, she continues to imagine things. He thin ks she is getting better in spite of her speculations, she knows she is getting better because of these speculations, her illness has its own certain effect and it even develops. John warns her several times that she must use her self-control to rein in her imagination, which he fears will run away with her. Of course, the narrator’s eventual insanity is a product of the  repression  of her imaginative power, not the expression of it.She is constantly longing for an emotional means, even going so far as to keep a secret journal, which she describes more than once as a â€Å"relief† to her mind. This illness progresses in a way that lets her see a woman in the wallpaper. She sees the same woman in different places and she thinks that the woman only gets out in daytime. She says, ? It is the same woman, I know, for she is always creeping along, and most women do not creep by daylight.? Lori Voth explains this part in a way that I totally agree with.She says that the woman who for some time is hidden in the background of the paper symbolizes the main character’s fear of presenting herself and her opinion. I agree that it is a symbol of fear because the narrator is a reflection of the hidden woman behind the wallpaper, which relates much to her. She is hiding in this house away from society, scared to say what she feels or what she wants. In my opinion, I think that this is one of the things that led to her depression, if the narrator was able to express herself from the beginning and not let her husband or anyone control her, as a result she may be in a better condition.Reaching the end, she doesn’t really care much about what anyone thinks. She starts showing certain actions that may confirm that she going insane, like peeling off all the paper, locking the door and throwing the key in the front path. On one hand it seems that she is gone insane, on the other hand, I think she is getting out of her cage, expressing what has been t here all along may be in a certain way that only satisfies her.In my own view as I discussed it before, each individual has a certain way of expressing their illness or more likely their feelings, and it comes with different ways of behaviour (outcome) depending on the person. This story takes the reader’s mind to different view of women. Women are usually known for being the quiet, sophisticated, and reasonable characters in society. This time the reader may be taken into the inner-most realms of women’s mind and experiences. The experience of the narrator in the ? The Yellow Wallpaper? hows that she is gone mad because her role in society is limited and her ability to express herself creatively is constricted. This inability for her to express herself in a meaningful way eventually leads her to associate herself with the woman in the wallpaper who looks to be, like the narrator, behind bars or in a cage. Some important feminine critics have seen the â€Å"The Yellow Wallpaper† not only an accurate representation of a situation of woman in a harsh culture but also a model for their own reading and writing practices (Davison 120).The yellow wallpaper represents several ideas and conditions and every time I read it a new view captures my eyes.

Energy Drinks Research Essay

Many energy drinks are found in the market and many people are consuming them without knowing the bad effects on their health, having the misconception that they help in enhancing and boosting the body energy. Ingredients: Other than the caffeine and carbohydrates energy drinks contain: B vitamins: Energy drinks contain B vitamins that exceed the daily-recommended amounts. Gingko: German pharmacological studies suggest that this herb increases blood flow to the brain and may be effective in treating depression and short-term memory loss. Guarana: An herbal stimulant popular in Brazil. The reason guarana is so stimulating is that it contains two to three times the caffeine of coffee. Carnitine: A compound generally found in animal foods that’s theorized to enhance fat burning and improve endurance performance. Mechanism: Energy drinks cause many things that include: Insomnia and alertness: Most energy drinks contain caffeine and herbal stimulants that stimulate the central nervous system, giving a sense of alertness. This stimulation can cause a person who is sleepy to wake up. However, it can also prevent a person desiring to sleep from dozing off. In addition, the caffeine in energy drinks blocks the effects of adenosine, a chemical in the brain involved in sleep. This in turn activates neurons in the brain as though there were an emergency, often preventing sleep and causing insomnia. Increased heart rate: When caffeine blocks adenosine and the neurons are activated, the pituitary gland releases adrenaline. This hormone makes the heart beat faster and consuming the large dosage of caffeine found in energy drinks can lead to high blood pressure and heart palpitations. Increased blood sugar: When adrenaline is released into the system, this causes the liver to release extra sugar in to the bloodstream for energy. In addition, energy drinks contain high amounts of sugar, which can be digested easily and also used as a quick source of energy. When consumed, the body experiences a sugar high then often crashes. The sugar enters the bloodstream, provides a blast of energy and when the sugar is burned up, 30 to 45 minutes later, the body usually experiences a sugar crash. At this time feelings of dizziness, slowed reflexes and decreased performance may occur. Dehydration: Caffeine is a diuretic or a substance, which causes urination. The caffeine in energy drinks causes the kidneys to move extra fluid into the urine, which can lead to dehydration if done while sweating during exercise. The high levels of sugar in energy drinks slow the absorption of water that dilutes the sugar in the bloodstream, enhancing dehydration. Also, consuming a drink with a high sugar concentration before an athletic performance can cause gastric distress and diarrhea, resulting in dehydration. Energy: Most energy drinks contain large amounts of caffeine, which can provide a temporary energy boost. Some energy drinks contain sugar and other substances. The boost is short-lived, however, and may be accompanied by other problems. Side Effects: Energy drinks can cause inflammation in the stomach; bleeding and ulcerations in the duodenum. While consuming energy drinks alone will not damage your liver immediately, prolonged consumption of certain ingredients in popular energy drinks may have ill long-term effects on your liver. For example, many energy drinks contain herbal concentrate products like kava kava or taurine. An overabundance of either of these herbal supplements can lead to liver damage or liver failure. For example, consuming large amounts of taurine may lead to complications in individuals with type-2 diabetes. Caffeine and Guarana affect the adenosine receptors in the brain. Caffeine also cause dopamine to be released in greater amounts which makes you feel more alert and energetic and happy though it does not provide any energy.

Performance Oriented Change - Case Study Example This extraordinary happening presents a universal point of disappearance for conjecture concerning the future of NPM inventiveness in three nations. The paper will expound on New Zealand as well the UK, as the two nations that have been frontiers of NPM, Australian Council of Social Services. (1998).The period commences with a description of NPM. The pressures for changing the public domain have also been investigated. More so, the paper develops in debating the emerging variations, conclusions as well as unrestricted realm transformation, Hood, C. and M.W. Jackson. (1991). The backdrop through which administrators operate is increasingly being altered, vastly diverse from that reflect by preliminary intellectual stalwarts of society management, Moore, Mark Harrison (1995). Societal bureaus are anticipated to correlate with each other, with nonprofit corporations and with citizen groups and to employ contemporary expertise methodically to administer and execute utility. Commanding demands that entail proficient resource use are evident owing to transnational markets as well as quasi-bazaar variables that have been asserting turbulent market forces. This framework is significant in the intellect that bureaus need to administer individual resources consequently but also compassionately and officially, Moore, Mark Harrison (1995). ... Moderately, the disciplines need to be incorporated in the civic administration prospectus in modes that ensure they will be integrated in learners' minds and hence their practice. Most essentially, civic administration pedagogy should be embedded to helping learners regarding civic corporations, government as well as governance, and the functionality of the collective department in an assortment of communal and financial system, Moore, Mark Harrison (1995).
