The Natural Behavior of Wolves

The Natural Behavior of Wolves Introduction Wolves belong to the broad class of the carnivorous animals. They belong to the Canidae family and thus, they are related to other carnivores like dogs and cats (Harrington, Fred, and Paul 263). No wonder their physical appearance is similar to that of the dogs.Advertising We will write a custom term paper sample on The Natural Behavior of Wolves specifically for you for only $16.05 $11/page Learn More However, they are much larger than the dogs. An adult male wolf grows larger than their female counterparts of the same age do. Most of the wolves are in Asia, North America, and Europe among other locations on the globe. The largest type of a wolf is the gray or timber wolf, which can live in any habitat from hot deserts to cool areas in the mountains. Just like dogs, wolves are social predators as depicted in the way they move and live like a family in groups known as packs. A pack is normally made up of not more than seven wolves, which largely depend on their number and the amount of food available for them. The animals carry out all their daily activities, which are mainly dominated by looking for food as a group. A couple who give birth to new members of the group heads each pack. â€Å"Unlike many mammalian systems, whereby the dominant males have got many mates and the subordinate few or non, the dominant male wolves may only have only one mate while the subordinates have none† (Harrington, Fred and Paul 221). After the young ones have grown up and can take care of themselves, they can move out of the pack to find their mates to start a new pack. Alpha is the name given to the dominant male leader of the pack. The dominant female is referred to as the alpha female. Hierarchy in the pack is observed as members of the pack show respect to the dominant or the superior ones. They do that through exhibiting submissiveness by the use of body postures and facial expressions. There is a limitation in the breeding proc ess because only the dominant partners can breed. In order to survive, a wolf must strive to achieve three things in life, which include a mate, food resources, and an area or territory. It can do this by killing an established breeder. However, in doing this, the wolf puts itself at the risk of being killed by its fellow wolves. The other option it can take is joining a pack, luring out a mate, and dispersing to an area that is not occupied (Mech and Luigi 25).Advertising Looking for term paper on biology?

A female wolf can give birth to between four to seven pups. The pups are all born blind and it takes them about a year to reach physical maturity. Summer time is a very important period for the breeding of the wolves. â€Å"During the three to four months after parturition, the pups must be a dequately fed to ensure that their physical development is sufficient to survive the rigors of the late fall and winter† (Harrington, Fred and Paul 81). Nevertheless, the pups do not become sexually mature until they are two years old. Naturalistic Observation of the wolves While human beings make use of physical borders to mark their territories, some territorial mammals make use of scent marking to distinguish the boundaries of the places where they live. Some animals like dogs and wolves scent mark mainly through urination and defecation, while others like the cats rub their body parts against surfaces. This way, animals are able to pass a certain message from one animal to another (Alcock 51). All animals apart from human beings lack the ability to talk in order to pass messages from one to the other. As for animals, they have different forms of communication. By keenly observing the way they behave, one can easily tell that all animals do communicate with one another. The y make use of facial expressions, sounds, and body language to pass different kinds of information. The sounds made by certain animals are different from those made by others, depending on the kind of message that is being passed (Alcock 53). All these also apply to the wolves whose inferior members show submissiveness to the superior ones by encircling them with their noses raised up. Just like dogs do on sensing danger, wolves also erect their ears in times of danger and in addition to that, they open their mouths wide. Just like the other carnivores, the wolves have strong muscles. They also have a strong sense of sense of smell and sight. ‘The sense of smell is probably the most acute of the wolf’s senses. Unlike human beings, wolves are strongly reliant on odors to acquire information about food or danger, as well as, all that concerns the outside world (Mech and Luigi 80). That way, they are able to kill animals, which are larger than they are in terms of size. To make getting food easier, they prey on the sick and weak animals and in addition to that, they eat very fast to avoid being robbed off their catch. The wolves normally target the deer, moose, the beavers, and the elk as their prey (Harrington, Fred, and Paul 35).Advertising We will write a custom term paper sample on The Natural Behavior of Wolves specifically for you for only $16.05 $11/page Learn More In case an enemy tries to steal their food, it will only be lucky to get the poor quality parts of the meat. This is because the wolves are very clever to feed on the best parts first once they get hold of their prey. In addition to their diet, the wolves feed on birds, berries, fish, worms, mice, and insects especially when they are not able to catch the large preys. There are rumors that wolves also eat people but it has not yet been proved true. The unique scent marking behavior of wolves Wolves are territorial by nature because they use their scents to mark their own territorial boundaries. It is the duty of leaders of the pack to urinate near the ends of their territories to mark them. â€Å"Wolf scent marking behavior used for territorial advertisement includes raised leg urination (RLU) and perhaps standing urination (STU) by males, flexed leg urination (FLU) and possibly squat urination (SQU) by female and perhaps defecation (SCT) and ground scratching (SCR)† (Mech and Luigi 25). The scent markings are said to reduce as one gets inside the territory. During patrols by the wolves in their territory, the number of scent markings is normally very high. The size of their territories depends on the nature of the habitat and the type of breed. It has been a little bit hard for researchers to track them down for study because of their frequent movements and their few numbers. There is a diminished wolf habitat and population because of the increasing human population and urbanization. The wolves’ natural habitat continu es to suffer from extinction as human beings use the habitants for settlement and other activities (Harrington, Fred, and Paul 120). The wolves spent most of their time at the core; a place that is approximately at the centre of the territory. For safety purposes, the places where the pregnant females give birth are always near the core. If the wolves loose all their off springs, they continue to live in the territory. Even when one of the breeding pair dies, the other one remains there until another mate comes (Mech and Luigi 28). The non-breeding members of the pack offer the protection to the breeding mother and the pups. When there is danger, wolves normally howl and bark to pass the message to the rest of the members of the pack. That does not mean that, they all gather there, they spread out in the vast territory only reassembling when the supply of food is scarce in order to fight for it.Advertising Looking for term paper on biology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Any wolf that does not belong to a certain pack is able to know the territories that have been occupied. This is because, by urinating near the edges of their territories, the wolves leave behind scent marks. They do it with one leg high up and that is followed by scratching the ground (Mech and Luigi 25). Additionally, it also enables them to know the presence of their prey and enemies, after which, they prepare themselves to deal with the situation at hand. The sad thing about their fascinating this natural behavior of wolves is the fact that it accounts for more than ninety percent of the lives lost by the wolves. Just as human beings behave when their territories are interfered with, the wolves fight for what belongs to them. Of course, the pack with the strongest or the largest number of wolves gets to win the fight leaving the members of the weak pack dead. â€Å"Wolves do fight to death in the wild and the losers are usually wolves encountered on a territory edge or inside a neighbor’s territory† (Harrington, Fred and Paul 5). A predator is more likely to kill one of the wolves if they are in a pack than when each is alone. Cases of deaths arising because of attacks by predators occur mainly when the animals are together. Implications of the Naturalistic Observation The observation made on the scent marking behavior of wolves indicates that it is one of their forms of communication. If they are able to sense the entry of an enemy into their pack and prevent other wolves from entering into their territory, then it only means one thing. They are able to pass a certain message by leaving scent marks through urinating at or near the edges of their territories. Once a foreign wolf senses the scent marks, it is able to understand that that particular territory is occupied by another pack. That way, a message has been passed, and the wolf does not interfere since it is aware of the consequences that could result because of crossing boundaries. Li mitations of the Research It has been difficult for researchers to do a thorough study of the natural behavior of wolves because of their low population and frequent movement (Harrington, Fred, and Paul 120). On the other hand, the scientific explanation behind the unique scent in the urine has not yet been established. Finally, it is not known if other animals, which are not wolves have the ability to recognize the scent of the wolves’ urine. Future Directions of the Research Researchers have been able to bring to the people’s understanding the scent marking behavior of wolves. The scientific explanation behind this unique behavior has not yet been ascertained. Therefore, researchers should go further in research to determine the chemical components present in the animal’s urine, which enables them to scent mark. In addition to that, they should also do thorough research to determine whether other animals apart from the wolves can be able to detect the scent. C onclusion From the above discussion, it is clear that almost all animals have their diversified ways of communicating with each other given the fact that they cannot express themselves through speech, as human beings do. As for the wolves, they communicate via scent marking. Scent marking is therefore, the unique way through which, wolves pass information to each other, especially with regard to marking their boundaries. This characteristic behavior is of great significance to the wolves because it enables them to survive, in other words, it is a survival tactic ((Harrington, Fred, and Paul). This is because the wolves are able to mark their territories and protect their prey from external predators. They are also able to note the entry of enemies and thus they can prepare to deal with them. Alcock, John. Animal Behavior: An Evolutionary Approach. Sunderland, Mass: Sinauer Associates, 2009.

Ashley Pondâ€Biography of a Murder Victim

Ashley Pond- Biography of a Murder Victim Ashley Marie Pond was born on March 1, 1989. Her mother, Lori Davis, was barely 16 at the time, almost a child herself. For the first few years of Ashleys life, she lived with her mother and her mothers high school sweetheart, David Pond. Eventually, the two married, and Ashley viewed David as her father. Childhood Ashley was described as an easy child who could entertain herself and one who adored being hugged. Basically, well-behaved Ashley seemed to live a fairly normal life for a child of parents so young. But then at about the age of nine or ten, Lori Pond divorced David Pond, and Ashleys world changed forever. The Truth About Her Biological Father During the divorce, the couple fought about child-support payments and a  paternity test was administered to determine if Ashley was indeed David Ponds biological daughter. To Ashley’s devastation, it was determined that he was not, but instead, a man named Wesley Roettger was her real father. She Admits to Being Sexually Abused She began to visit her biological father, staying with him on the weekends. It was during this time that friends and family noticed she was growing increasingly sullen and confrontational. She began to resist visiting her father until she finally admitted to her mother that Wesley Roettger had been sexually abusing her. In January 2001, Roettger was indicted on 40 counts of raping and sexually abusing Ashley. He pled no contest to one count and was released. Ward Weaver Enters Her World During the following months, the police were called out to the Pond apartment for various reasons including an allegation that Pond was drunk and neglecting the children. By April 2001, Ashley Pond was spending a lot of time over at the house of a friend, who was the daughter of Ward Weaver. In early spring, a report was made by Linda Virden, Ashleys reading teacher, to Gaffney Lane Elementary principal Chris Mills, that she saw Ward Weaver kiss Ashley on the lips. She Finds Comfort at the Weaver Home According to the Portland Tribune, Ashley spent almost the first half of 2001 with the Weaver family even joining Ward Weaver, his girlfriend, and Weavers daughter on a two-week vacation to California  in late June, early July. The calls to the police about disturbances at the Ponds home continued over the next few months and Ashley spent more and more time with the Weavers. Weaver Is Accused of Sexually Abusing Her In early August, Ashley confided in her reading teacher, Linda Virden, that Ward Weaver was molesting her and threatened to testify against her in her fathers rape trial. Earlier in April she also accused two other men of molesting her  but recanted her statements. Possibly the fear of no one believing her kept her from pursuing charges against Weaver. Paperwork Slips Through the Cracks Once the accusations were made, she stopped going to Weavers house and felt ostracized by Weaver, Weavers daughter, and friends of Weavers daughter. Due to the sloppy handling of the paperwork by county officials regarding Ashleys accusation, Weaver was never investigated or charged with sexually abusing Ashley at that time. Life Begins to Settle Down Throughout the following fall, Ashleys life seemed to settle down. Her grades were improving and she was fighting less with her mother. Some of her bubbly personality seemed to return. As Christmas approached it has been suggested that Ashley and the Weaves had partially renewed their friendship. Ashley Pond is Murdered According to the Portland Tribune, on Jan 9, 2002, Lori Pond heard Ashley say goodbye around 8:15 a.m. as she headed out to catch her school bus at a stop near Weaver’s home. What happened to Ashley after that time is unknown. What is known is that at some point before she died, she consumed possibly as much as five shots of whiskey. On the weekend of August 24-25, the body of Ashley Pond was found inside a barrel buried in a hole in the backyard of Ward Weavers rental home. A concrete slab had been poured over the hole. According to Weavers son, Francis Weaver, his father confessed to him that he killed Ashley Pond, although the exact details of the confession have changed from time to time. On October 4, 2002, Ward Weaver was indicted for the murder of Ashley Pond and of 16 other counts including sex abuse, attempted rape, aggravated murder and abuse of a corpse all of which he pled not guilty. On September 22, 2004, Ward Weaver plead guilty to killing two of his daughters friends then hiding their bodies on his property. He received two life sentences for the deaths of Ashley Pond and ​Miranda Gaddis.

Early Pioneers of the Hotel Industry; How their Contributions and Essay

Early Pioneers of the Hotel Industry; How their Contributions and Management Style shaped Todays Modern Hotel - Essay Example According to Britannica Online, Ellsworth Statler introduced the common hospitality slogan â€Å"the customer is always right† (2013). Like many hotels found today, Statler’s incorporation of amenities were found to offer quality service to customers. Statler stated, â€Å"All I want to do is to have more comfort and conveniences and serve better food then any of them have or do, and mine will be at a price ordinary people can afford† (Turkel, 2005). His vision and goal was very much like the goals of management leaders today. Statler’s vision for a better future brought forth the following innovations: â€Å"ice water circulating to every bathroom, a telephone in every room, a full-size closet with a light, a towel hook beside every bathroom mirror, a free morning newspaper, and a pin cushion with needle and thread† (Turkel, 2005). Ellsworth Statler portrayed effective management through his efforts of making staff focus energy on guest satisfactio n. Statler’s employed operational strategy was achieved through the Statler Service Code which was a pledge for employees to work by in offering the best service possible (Kkapanek, 2012). This service code is similar to the codes that hotels work by. For hotels this service code is known as the mission and vision of a hotel, it informs guests of what that hotel is all about. Ellsworth Statler was not the only innovative leader to change the hotel industry (Ellsworth, 2013). Cesar Ritz was the pioneer that established a name by managing with excellence. Cesar Ritz also started his career in the restaurant industry and progressed his way up to managing hotels in Paris. Eventually, Ritz became the founder of elegance in hotels through his drive for vision. â€Å"He had the gift and intuition to recognize the important elements of hospitality and he used them well and consequently† ("Caesar ritz," 2013). Cesar Ritz designed his hotel with

Critically analyse the competing views articulated by Essay

Critically analyse the competing views articulated by capital-exporting countries and capital-importing countries in relation to the nature of compensation for the expropriation of foreign property - Essay Example and other countries. Similarly, Mexico nationalised all American interests in 1938 and refused to pay compensation to the property owners. Their stand, as capital importing countries was that when they initiated economic and social reforms both the nationals and foreign entities suffered or enjoyed equally and hence, there was no question of compensation especially when they had no sources or means or capacity to compensate the parties. On the other hand, capital exporting countries insisted that they were entitled to minimum standard of treatment which should not be just equal to the treatment given to the nationals. Many equitable principles have evolved in the process each of which has been fairly argued for and against. The capital importing countries held the view that when foreign entities enter into their states they are supposed to merge their destiny along with nationals and work together for the country’s betterment and therefore cannot expect any better treatment th an available to nationals. All these controversies had been due to absence of settled international law prior to world war period and during the immediate post war period. As a solution to the much vexed issue, bilateral and multilateral treaties have come to stay as contracts with legal binding to address similar situations during their operating periods. This paper proposes to examine the views of the capital exporting and capital importing countries in the matter of compensation payable for taking of the foreign investor’s (capital exporting) properties by the host states (capital importing). Since there is no enactment of international law as such, only by the customary law and equitable principles, it can be decided whether an expropriation resorted to by the host state is justifiable or not. With this perspective, this paper will examine the customary law and various instances of expropriations across the world and

Culture and Disease Essay Example for Free

Culture and Disease Essay Culture is a pattern of behavior and thinking learned, shaped and shared by Europeans and Americans. It is their growing and developing bank of knowledge, experiences, beliefs, values, attitudes, meanings, hierarchies, religion, notions of time, roles, spatial relations, concepts of the universe, material objects and possessions gained through generations of individual group work (Williams 1976). Any discomfort, dysfunction, distress, social problems, and alterations of behavior for Europeans and Americans are considered a disease. It is a change that disrupts the normal function of the body. It is initially believed to be caused by curses, evil spirits, or night vapors. However, in the mid-19th century the discoveries and findings of scientific works by Louis Pasteur and Koch concluded microorganisms or germs are the pathogens of infectious diseases which usually gain entrance into the body. These are microorganisms that are able to infect a host and produce a disease (Miller 2003). Subsequent studies and researches improved the concepts of healthcare. In the 21st century, Western Science of Medicine means accuracy. It is the name of the trend. Its subject the human body is likened to an outstandingly complex machine that can be figured out, customized, renovated, and its health defined and described in strictly clinical terms. Medical experts called Physicians can identify and eliminate disease-causing or etiologic organisms that originate outside the body, Surgeons evolved to be incomparable experts in dealing with acute trauma and distress, and epidemiologist uncovers the factors that determine the frequency, distribution, and determinants of diseases in human populations. These factors include the characteristics of the pathogen, the susceptibility of human population resulting from overcrowding, lack of immunization, nutritional status, inadequate sanitation procedures, locations or reservoirs where pathogens lie in wait, and the various means by which infectious disease is transmitted. Ironically, resurgence of infectious disease such as tuberculosis occurred brought about by the emergence of another infectious disease HIV/AIDS (Burton 2004). The existence of epidemic and communicable diseases in specific areas were found to follow geographic patterns. Diseases like Poliomyelitis caused by over population infected Brazilian children population, and it also infected older age Scandinavian and Americans; cholera, yellow fever and dengue infected Indians in India as a result of poor sanitation; Plague brought about by rodents are cases in the Western United States of America, and in China, it is carried by rodents and fleas infecting Chinese. These findings were important concepts for public awareness to guide travelers and servicemen (Duffy 1953). Body Tuberculosis is a chronic mycobacterial infection of the lower respiratory tract characterized by fever, night sweats, weight loss, productive cough, shortness of breath, chest pain, coughing up blood and hoarseness. It may infect lymph nodes causing systemic disease like kidney disease, urinary bladder disease and bone disease (Burton 2004). The dynamics of infection follows the following pattern: Sources of Infection Modes of entry Mechanism of disease Pattern of infection Portals of exit. Mycobacterium tuberculosis a slow-growing, acid-fast, Gram-variable bacillus is an aerobic bacillus species capable of reproducing within 16-20 hours. It is the etiologic agent of the disease called tuberculosis (Burton 2004). Mycobacterium tuberculosis developed resistance to treatment drugs. It is the second leading killer of adults in the world, with more than 2 million TB-related deaths each year (Burton 2004). Ironically, one of the endemic diseases in the United States of America is this bacterial disease called tuberculosis. In 2004 Centers for Disease and Controls, Atlanta, GA reported 14, 517 tuberculosis cases. The resurgence of tuberculosis in the United States of America in the 1980’s through 1990’s primarily resulted from the HIV/AIDS epidemic and the multi-drug resistant strains of M. tuberculosis (Burton 2004). Identification and recognition of the characteristics of the pathogen, the susceptibility of human population resulting from overcrowding, lack of immunization, nutritional status, inadequate sanitation procedures, locations or reservoirs, emigration and migration of men and animals, and stress makes people immunosuppressed resulting to infection, considering that pathogens may come primarily from infected humans, sometimes from primates, cattle and other infected mammals (Burton 2004) . There are various sources from which tuberculosis can be acquired and transmitted. It may be via airborne droplets produced by the infected organism during coughing, sneezing, even singing and prolonged direct contact with infected individuals ((Burton 2004). Prevention, Precautions, Sterilization, disinfection and Patient care would all involve airborne precautions (Burton 2004). In Clinical practice, disinfection and sterilization as well as laboratory procedures were employed being a necessity. Their scientific basis has been developed only during the past century. These important procedures are: Sterilization which is the destruction or complete removal by filtration of all forms of microorganisms including their spores; Disinfection is the destruction of many microorganisms but not usually bacterial spores; Antisepsis, is the destruction or inhibition of microorganisms in living tissues thereby limiting or preventing the harmful effect of infection; Static agent would inhibit the growth of bacteriostatic microorganisms; Bactericidal agent would kill the microorganisms; Sterilizers are chemicals which under controlled conditions kill spore-forming bacteria. These agents which perform the above functions were divided into physical agents and chemical agents. With these mechanisms, Epidemiologist and Social psychologist in the United States of America helped contribute to the study of health and to the interventions to improve people’s well-being and quality of life by promoting health and preventing illnesses. They identify psychological factors that might influence illness, and identify improved ways in which health care is delivered. This is also a form of proposition for the improvement of the health of the population by promoting healthy choices and preventing people from becoming ill. Psychologists are persuasive by appealing to fear for the negative health consequences, subsequently encouraging American families, peer and schooling young adolescents to change their health behaviors by redirecting their behavioral intentions. This is in line with the concept that the actions taken by people to safeguard their health are influenced by factors such as general health values, perceived susceptibility to illness, perceptions of illness severity, expectations of treatment success, self-efficacy, perceived barriers and benefits, and cues to action. Healthy habits that are currently recommended are vigorous regular exercise, quitting smoking, limiting alcohol intake, eating healthy foods, and getting enough sleep. Even so, considering the increased cultural mixing Of the United States of America, programs or lessons in scholastic trainings are incorporated as designed to increase intercultural communications as cultural patterns affect how people make sense of the many aspects of health care: the meanings that people give to health and illness, the causes of diseases, the means to prevent illnesses, appropriate cures, and the types of individuals most qualified to provide care and attempt to cure. In this context, magico-religious approach, holistic approach and biomedical approach are not set aside, but, the healthcare system of the United States of America is typically focused on the individual patient as the source of the medical problem in need of a cure. This is rather the biomedical approach adopted to address the issues of illness and wellness. It considers people health regardless of culture to be driven by biochemical forces. Wellness is achieved by understanding that the biochemical reaction is activated. Illness happens when a part of the normal human body metabolic activities is altered. Treatments are provided by Medical health practitioners like Doctors and Nurses, thus bringing back the normal course of bodily metabolic activities supportive of good health (Lustig 1996). In 1953 Dr. Louis H. Bauer of New York, USA as a secretary General of the World Medical Health Association outlined the major task to address medical care need from their time on, such as: 1) Rural community work to establish facilities and to encourage physicians participation; 2) provide medical care all depressed areas : 3) Extend public health coverage to depressed areas; 4) Evolve strategies to address care needs people with inborn disorders; 5) Provide insurance programs to people specially senior citizens and the disabled; 6) Eradicate graft and corruption in the Medical practice; 7) General public protection for regular Medical services; 8) Renew medical societies; and 9) Medical Health ethics education for the Medical Health practitioners (Perkins 1993). Conclusion With the advent of post-industrial age marked by the ubiquitous appearance and usages of television and the computer, supposedly a reliable indicator, most Americans should be healthy and wealthy. Being so, it could be enough to affect longevity positively, primarily through lifestyle choices, rather than lack of food or shelter and diseases (Lustig 1996). However, Studies revealed that even the introduction of Medicare in the United States, bringing the poor substantially at par with the rich in terms of health care and medical services did not eliminate or even markedly reduced the large differential mortality. In contrast, life expectancy in Japan is far above all the rest of the countries in the world. The life expectancy for males is 78 years while the life expectancy for females is 85 years, in spite of half the level of spending for healthcare than that of the United States of America amounting to around $2,000 per person, 7. 4 percent of GDP (Powell 1990). The technology used in the Japanese health care system is similar to that used in the United States of America, but, the flow of funds, the quantity and intensity of use is considerably different (Powell 1990). In Japan, all citizens are free to choose any physician and hospital. Physicians may be General Private Practitioner providing primary and secondary care, while Specialist works in hospitals. Hospitals may be large and public university hospitals with medical school, research facilities, and outpatient department for primary care while small time private practitioners have small facilities and less sophisticated treatments (Powell 1990). Knowing that tuberculosis is transmitted via airborne droplets produced by the infected organism during coughing, sneezing, even singing and prolonged direct contact with infected individuals, preventions and precautions are better than an ounce of medicine after infection.

Quantum vs. Classical Mechanics :: essays research papers

Classical and Quantum mechanics are the two main fields of mechanics in physics. Classical mechanics came a few hundred years before Quantum mechanics. Subsequently it is less accurate and less reliable then the more recent mechanic field of Quantum mechanics. Despite being outdated, Classical mechanics can still be used for many everyday problems with bigger and slower moving objects. However, when dealing with extremely fast moving or small subatomic particles a Classical approach will not produce sufficiently accurate results as was the case around the 19th century.   Ã‚  Ã‚  Ã‚  Ã‚  Difficulties with the Classical mechanics theory came right around the 19th century. First was the Ultraviolet Catastrophe. Experimental data when testing blackbody radiation was found to be inconsistent with Classical mechanics. The data showed that as the wavelength of the incoming radiation approaches zero, the amount of energy being radiated also approaches zero, whereas Classical mechanics says the emitted energy is infinite. The second difficulty with the theory was its inability to correctly describe the photoelectric effect. The photoelectric effect says that photons from a surface are released when light hits it. Classical mechanics says that electrons will be emitted from a metal by light waves with any frequency as long as the intensity of the light is strong enough, and even if it is weak over a long enough period of time electrons will eventually be emitted. The theory was proved incorrect after experiments showed that light under certain frequencies did not produce the photoelectric effect on the metal, which meant that the emitting of electrons is related not to intensity but the waves frequency. A new string of mechanics, Quantum mechanics, was created in order to resolve the incompatibilities of Classical Mechanics. A main difference between the two fields of mechanics is the make up of the atom. In Quantum mechanics electrons in an atom are outside of the nucleus in specific orbitals around the nucleus that they can jump from one to another only when a specific energy level is reached, and can never be in-between the specific orbitals. Also Quantum mechanics says that a photon is released only when an electron jumps from a higher energy level to a lower energy level, or a higher energy orbital to a lower energy orbital. Classical mechanics, contradicting this, says that an atom is constantly emitting radiation. Quantum mechanics describes light as both a wave and a particle, depending on the situation.

Higher education Essay

College and high school have the same goal; which is to educate students and give them knowledge that will help them along the way in life. They both allow for growth and development, but have two completely different experiences. While high school is mandatory and helps prepare students for college academically, it can also teach life lessons that will never be forgotten. College is typically for students who would like to continue their education at a higher level and work towards achieving their career goals. College and high school are both stepping stones towards a brighter future. The majority of students in America have attended high school. It is a requirement for students ages 13-18. Students are required to complete grades 9-12, or have a certain amount of high school credits to receive a high school diploma. In California, the â€Å"CAHSEE† has to be passed. The CAHSEE is the â€Å"California High School Exit Exam† which ensures that students are able to complete grade level math, writing, and reading. On the other hand, college is a place that not every high school student has attended. College is a choice. Some people do not attend college; there are other choices such as working a full time job or even joining the army. College is for students who would like to continue their education to obtain a degree in their field of study. Butler 2 Because high school is mandatory it is also free. Students are only required to pay for items such as yearbooks, class pictures, and prom tickets. College on the other hand, is very expensive. Some colleges, such as the University of Southern California, are over 20,000 a semester. On the other hand, other colleges such as community colleges are not as expensive as private colleges or ivy league schools. They cost about 40 dollars a unit. In college, students have to pay to attend classes, pay for books, and parking passes if they have a car. They also have to pay more if they are planning on living in a dorm or apartment. Student fees such as health fees and ID cards are all required to be paid by certain deadlines if they would like to get classes. College, overall, can be very expensive. Another difference between college and high school is that in college students are able to choose their own classes. There is also more freedom  when choosing classes, students can choose whether to have a class in the morning or at night and the exact times the classes meet. Students are able to choose classes based on interests and depending on what classes are needed to getting a degree in their field of study. If the student wants to drop a class, the student is allowed to. In the first two years of college, general education classes are recommended. In high school, classes are picked for the students based on how the student did in the previous year. Most of the time school starts at a certain time, mostly in the morning, and lets out in the afternoon. There is a routine schedule everyday. If the class is passed, Butler 3 then the student can go to a higher level. The only classes students in high school are able to choose are elective classes. Those are classes like art, choir and band. Classes are also much different in size. If a student attends a university, college classes can contain many students in one class, such as a lecture hall. The class sizes are huge and can contain more than 100 students in one class. Attending a community college, some classes are smaller but not as small as high school classes. In high school, classroom sizes hold about 20 to 30 students. This allows teachers to connect with students in a more intimate way and give that one on one help that may be needed. In college, sometimes students are not given the luxury of having one on one time with a teacher, so the students has to take responsibility and try to contact the instructor or get a tutor if more help is wanted. There are numerous differences between high school and college responsibilities. Entering college can be a wake up call for many new students. Going from high school to college is a big step in life. In college, there are many deadlines that need to be met, such as applying for classes on time and paying fees when they are due. Everyone is responsible for going to class and getting their on time. If students would like to drop a class, the student is responsible for dropping the class, not the professor. College assignments are much harder then high school assignments are. Everything is much more tedious and right to the point. Being a college student, teachers do not have the time to give one on one help, so study time or studying with a group is a must. Being in college really prepares students for the  Butler 4 next step, which is embarking a career. In high school, there are not as many responsibilities. Students are responsible for going to class and passing the classes but even if they decide to â€Å"ditch† a class, the school will usually call the home and inform their parent. Other responsibilities include doing homework and completing assignments. High school is not nearly as strict as college. In college, there is much more freedom. Often times, when students graduate from high school, they attend a school outside of the state or in another city and live in dorms or apartments. This creates even more freedom. Living out of state and attending college can be a whole new experience for a high school graduate. Going to college allows them to â€Å"grow up† and teaches them how to be a responsible adult and do things on their own. There is more freedom because students can pretty much do whatever they want, when they want. In high school there is not much freedom. It is all a routine. Students are forced to go from class to class and stay in class for the whole time period unless there is an excuse for class to be missed. There is no freedom to come and go whenever. Although there are many differences, college and high school have similar aspects such as social life, classes, and earning a degree. Many people start to obtain a social life starting in high school. That is where cliques start to form and people figure out there identity. Many students begin dating and having break ups during high school, as in college. Also, there are many clubs that students can get involved in and build relationships in. In college, general education classes are required. Most Butler 5 times, these classes are review of what was learned in high school such as math, science and English. Students know what general education classes they have to take based on there test scores. High school and college are both very important and should be attended. They are both great experiences and both can be learned from. Many students attending college plan on getting a degree and starting a career in their field of study. College can teach you many responsibilities and techniques that can help in the future. Although high school and college have differences, they can both give knowledge and understanding about the world and what needs to be learned.

Library Leaders

Virginia Proctor Powell Florence occupies a special place in the history of the African American population. She was particularly a big inspiration to the women of Africa descent in America being the first woman to pursue successfully a career in the library studies. She was born on the first October 1903; she went to a local public school in Wilkinsburg Pennsylvania. Her parents died when she was still at her tender age. She was living with her aunt. In 1915, she cleared from high school and proceeded to join Oberlin College graduating with a bachelor’s degree in English. She secured a job in Minnesota working as a secretary as the persistent racial discrimination hampered, temporarily, her dreams to work in her former high school (Kinder, Sean, 2008) She had a big dream of pursuing library science and she applied for a place in the Camegie library school, successfully completed her diploma studies in 1922. However, being a pioneer among blacks, she could not be awarded a diploma, this only happened after a number of years later. Her dream career commenced in the New York public library for a number of years before her appointment into Seward high school Brooklyn, as a librarian. She got married to Charles, her fiancà © who had greatly supported her in her career. She still pursued her career working at Cardoza High, Washington DC. She then moved to Maggie L. walker senior high still as a librarian. A look at her life reveals a strong-charactered lady who was able to trend a path that had been shunned by many, winning admiration across the racial divide and no doubt propelling the importance of education in the community to higher level. Even at the time of her death, in 1991, Virginia proctor Powell Florence, an educationist and a career librarian was an inspiration to many. Meeting this respected lady is truly humbling. There are a number of renowned educators that I would like to see join Virginia Proctor Powell Florence and I for tea. Among the famous black American educators, I would most respectably like to meet Virginia lacy Jones and Joseph Henry Reason. There are prominent figures in library leadership, on top of Powell Florence, I admire greatly. So humble and yet so giving. They have contributed eminently to education (Dawson, 2000). Doctor Joseph Henry Reason and Virginia Lacy Jones CVs’ run long, with academic qualifications, experience and personal accomplishments. They both have such inspiring profiles that cannot be matched by many in their generation. Overcoming so many odds to claim a place in the academic circles and history. Dr. Joseph H. Reason lived a life committed to extending knowledge, at the time of his death; he had been the director of Howard university libraries for over twenty years, with strings of accomplishments and projects in the university. Born in 1905, Joseph has many degrees to his name that only can dream of. He has been to New Orleans, Howard, and in the university of Pennsylvania, he took a Bachelor of Science degree specialising on library science then went ahead to get his PhD from the catholic university of America (Http://Www.Allctr.Edu/Documents/October2007oo1.Pdf). He was also the director of number university libraries including A&M university libraries. He helped initiate a number of university projects and building sites. He was a trustee in the Eckerd College. He has also featured in a number of taskforces and under his tutelage, saw the approval of Howard university library as a member in to the association of research libraries. (ARL). The list of his accomplishments run long, but is clearly inspiring. Meeting such a person would be a dream come true considering I don’t usually meet such high calibre persons in academics (Marcus Bruce Christian, 2007). Virginia lacy Jones accomplishments are equally impressive. She was born in 1912 and died in 1984. She received her degree on library studies. She was brought up in West Virginia with Ohio being her birthplace. Her first job in the library was in the Louisville municipal college. She was later to return to the home of her former school, Hampton institute library to get her degree, which she did in social studies. She went back to Louisville to her former workplace and helped found the Kentucky Negro Education Association in Louisville. In 1936, she was appointed to head a program that sought to initiate training to blacks for librarianship. Amidst much opposition from whites over her pay, as she was being paid similar amounts, she made it through and was promoted in to the position of head librarian back in the municipal college (Reinette F. Jones, 2002). Immediately after this promotion, her friend and mentor, Florence Curtis helped secure a master scholarship in library science. She got the masters from the University of Chicago in 1938 and was to get a place in the Atlanta University as the cataloguing librarian. She was named a member of the faculty. She got her PhD in 1945 and at the same time married a French professor. She was the second woman among the blacks to get such high qualifications in academics. Her accomplishments after that run long and she was appointed by President Lyndon B. Johnson on one of the library presidential advisory committees. With such impressive rà ©sumà ©s who would not want to meet these three distinguished figures. References Reinette F. Jones, 2002. Library Service To African Americans In Kentucky. Mc Far Land.

How to Discipline Without Stress, Punishment, or Rewards

How to Discipline Without Stress, Punishment, or Rewards Young people today come to school with a different orientation than past generations. Traditional student disciplining approaches are no longer successful for far too many young people. For example, a parent related the following to us after a discussion of how society and youth have changed in recent generations: The other day, my teenage daughter was eating in a rather slovenly manner, and I lightly tapped her on the wrist saying, Dont eat that way.My daughter replied, Dont abuse me.The mother had grown up in the 1960s and volunteered the point that her generation tested authority but most were really afraid to step out of bounds. She related that her daughter was a good child and added, But the kids today not only disrespect authority, they have no fear of it. And, because of rights for young children- which we should have- its hard to instill that fear without others claiming abuse. So, how can we discipline students, so we as teachers can do our jobs and teach these young children who refuse to learn? In many cases, we resort to punishment as a strategy for motivation. For example, students who are assigned detention and who fail to show are punished with more detention. But in my questioning about the use of detention in hundreds of workshops around the country, teachers rarely suggest detention is actually effective in changing behavior. Why Detention is an Ineffective Form of Punishment When students are not afraid, punishment loses its effectiveness. Go ahead and give the student more detention that he simply wont show up to. This negative, coercive discipline and punishment approach is based on the belief that it is necessary to cause suffering to teach. Its like you need to hurt in order to instruct. The fact of the matter, however, is that people learn better when they feel better, not when they feel worse. Remember, if punishment were effective in reducing inappropriate behavior, then there would be NO discipline problems in schools. The irony of punishment is that the more you use it to control your students behaviors, the less real influence you have over them. This is because coercion breeds resentment. In addition, if students behave because they are forced to behave, the teacher has not really succeeded. Students should behave because they want to- not because they have to in order to avoid punishment. People are not changed by other people. People can be coerced into temporary compliance. But internal motivation- where people want to change- is more lasting and effective. Coercion, as in punishment, is not a lasting change agent. Once the punishment is over, the student feels free and clear. The way to influence people toward internal rather than external motivation is through positive, non-coercive interaction. Heres how... How to Motivate Students to Learn Without Using Punishments or Rewards Great teachers understand that they are in the relationship business. Many students- especially those in low socio-economic areas- put forth little effort if they have negative feelings about their teachers. Superior teachers establish good relationships AND have high expectations. Great teachers communicate and discipline in positive ways. They let their students know what they want them to do, rather than by telling students what NOT to do. Great teachers inspire rather than coerce. They aim at promoting responsibility rather than obedience. They know that OBEDIENCE DOES NOT CREATE DESIRE. Great teachers identify the reason that a lesson is being taught and then share it with their students. These teachers inspire their students through curiosity, challenge, and relevancy. Great teachers improve skills that prompt students to WANT to behave responsibly and WANT to put effort into their learning. Great teachers have an open mindset. They REFLECT so that if a lesson needs improvement they look to themselves to change BEFORE they expect their students to change. Great teachers know education is about motivation. Unfortunately, todays educational establishment still has a 20th-century mindset that focuses on EXTERNAL APPROACHES to increase motivation. An example of the fallacy of this approach is the defunct self-esteem movement that used external approaches such as stickers and praise in attempts to make people happy and feel good. What was overlooked was the simple universal truth that people develop positive self-talk and self-esteem through the successes of THEIR OWN EFFORTS.

10 Ways to Use Smartphones to Teach English

10 Ways to Use Smartphones to Teach English Smartphones are here to stay. For English teachers, that means we need to either ban iPhones, Androids, Blackberries, and whatever next flavor arrives, or we have to learn how to incorporate the use of smartphones into our routine. Students who sit in class and use their iPhone or Android are missing out; however, its also true that students are going to use their smartphones if they havent been taken away. Here are ten tips on how to constructively allow the use of smartphones in class. Some of the exercises are just variations on traditional classroom activities. However, encouraging students to use smartphones to complete these activities will help them learn to use their devices to actively improve their English skills. Finally, its important to insist that smartphone or tablet use in the classroom is approved only as a tool during a specific activity. In this way, they may not be tempted to use their smartphones for other reasons during class.   Vocabulary Exercises Using Google Image Search A picture is worth a thousand words. Have students use their smartphone to look up specific nouns on Google images or another search engine. Youve all seen how a visual dictionary can greatly improve vocabulary retention. With smartphones, we have visual dictionaries on steroids. Translation Activities Encourage students to read using three phases. Only allow smartphone use in the third phase. Students are pleased because they can look up words. However, theyre developing good reading skills by not immediately translating every word they do not understand. Read for gist: no stopping!Read for context: How can the words surrounding unknown words help with understanding?Read for precision: explore new vocabulary using a smartphone or dictionary. Use Apps for Communication Activities We all communicate with our smartphones in different ways depending on different apps. In other words, texting with a messaging app is bound to be different than writing an email on your computer. Take advantage of this and promote activities that are specific to a given context. One example might be to have students text each other to complete a given task.   Practice Pronunciation You can use smartphones to record audio as you model pronunciation for your students. For example, gather suggestions, then ask students to open a recording app. Read five different ways to make a suggestion aloud. Pause between each suggestion. Have students go home and practice mimicking your pronunciation in the pause between each suggestion. There are many, many variations on this theme.   Another great use for pronunciation is to have students change the language to English and try to dictate an email. Theyll have to work really hard at word level pronunciation in order to get the desired results. Thesaurus Activities Have students search on the phrase words like... and a host of online offerings will appear. Encourage students to use their smart phones during writing class in this manner while focusing on developing a wider range of vocabulary. For example, take a simple sentence such as The people spoke about politics. Ask students to come up with a number of versions using their smartphones to find substitutes for the verb speak. Play Games This is something we normally shouldnt encourage in class; however, you might encourage students to write down phrases they experience while playing games to bring into class to discuss in more detail. There are also a number of word games such as Scrabble or word search puzzles that are actually instructive as well as fun. You can make room for this in your class as a reward for completing a task, just make sure to tie it to some sort of report back to the class. Track Vocabulary There are a wide variety of MindMapping apps available, as well as a myriad of flash card apps. You can even create your own flash cards and have students download your set of cards to practice in class.   Practice Writing Have students write emails to each other in order to complete a specific task. Change up the tasks to practice different types of register. For example, one student might write a product inquiry with another student replying to the inquiry with a follow-up email. This is nothing new. However, just using their smartphones can help motivate the students to complete the task. Create Narration This is a variation on writing emails. Have students choose photos they have taken and write a short story describing the photos they have chosen. By making the activity personal in this manner, students engage more deeply with the task. Keep a Journal One more writing exercise for the smartphone. Have students keep a journal and share it with the class. Students can take photos, write descriptions in English, as well as describe their day.

Media and Reality Research Paper Example | Topics and Well Written Essays - 2000 words

Media and Reality - Research Paper Example According to Friedman (2002), we live in a technological phase since persons spend several hours on electronic screens conversing or inquiring on diverse topics. Evidently, television programs; for example, â€Å"All in the Family† can alter people’s perceptions of individuals from other races (Dill, 2009). Exposure to this episode can influence the person to generate an optimistic attitude to other races and compel them to initiate interactive relationships. Such a program can instigate a substantial urge to destroy racial bigotry; thus, becoming a force of societal changes (Dill, 2009). However, this program can differ from the realistic situations existent in the country. Racism can be extensive in numerous areas; however, the program acts on our perception since it shuns the reality. Indeed, reality is our discernment of the truth despite the obvious anomalies in the details that can be existent in the background. Television commercials are created in entertaining f orms to lure the audience. They usually encompass an appealing story displayed repeatedly in attractive designs hoping it will induce the audience to ponder on the commercial message. Perception and Reality Friedman (2002) affirms individuals are currently living in two dissimilar worlds that have contrasting realities. One entails the world that the media channels portray and a world that one experiences by engaging in real processes. There are instances where the conceptualization of these diverse worlds significantly varies; thus, shocking the people since it is differs from the expectations (Dill, 2009). As such, the Media controls how we react to gender roles, sexuality, politics and institutional matters (Friedman, 2002). For example, the American Media relays numerous reports on the security threat of other nations to its citizens. Thus, the media portrays violent content leading to a feeling of paranoia amidst the citizens. Consequently, the sensation of exterior threats and violence propagated by the media was instrumental in propelling the US invasion witnessed in diverse countries; for example, Iraq and Afghanistan. Moreover, the obsession of the media with potential repercus sions of external threats continues to influence airlines, immigration authorities and corporations, which have boosted their security protocols. Interestingly, the repetitive conveyance of the Muslim countries as threats continues to shape the perception of the US populace towards Muslims (Dill, 2009). As such, there were incidences of racial attacks towards American Muslims who fail to engage in the acts of distant relatives. Indeed, this is one of the adverse implications of media on societal perceptions. According to Dill (2009), such influential power of the media is escalating to controversial levels since it is instigating widespread changes in the mannerisms and circumstantial implications on individual lives. Technological advancements are consistently becoming a mechanism of
