Childrenââ¬â¢s Functional Health Pattern Essay Example for Free
Childrenââ¬â¢s Functional Health Pattern Essay Toddlers believe rules are absolute and behave out of fear of punishment. The toddler will respond with good behavior for positive feedback. Theseà values and beliefs are learned. Preschoolers frequently express their values by stating who or what they like or what they want to be when they grow up. Preschoolers receive modeling of values from involved adults, peers, as they develop their morality. School-Age childrenââ¬â¢s values come from religion, cultural, and parental values influences. These factors shape a childââ¬â¢s moral development, and concept of right and wrong. School-age children are able to make decisions related to moral and ethical issues. Parents may cater to their toddler when they are misbehaving, giving them more attention when they are bad than when they are good. This make the toddler believe that behaving badly gets their parents attention. Parents need to remember to reward good behavior, and to emphasize rewards for acceptable behavior and minimizing attention for unwanted behavior. Parents may not have firm and established rules, making it confusing for the toddler to distinguish right from wrong. Peers or inappropriate content on television can negatively influence preschoolerââ¬â¢s values and beliefs. Parents may have a poor morals and value system themselves, inadvertently teaching their preschoolers the same behaviors. School-age children may bend to peer pressure to gain the acceptance of their peers. School-Age children may cheat due a desire to win, or pressure from their parents and peers to be great. Short Answer Questions Address the following based on the above assessment findings. Expected answers will be 1-2 paragraphs in length. Cite and reference outside sources used. 1) Compare and contrast identified similarities as well as differences inà expected assessment across the childhood age groups. Across the stages of development from toddler up to school age children there is a significant difference in the amount of guidance needed and the amount independence required. The differences are evident when examining how each developmental phase interacts and responds within each health assessment pattern. Toddler and preschool children need more structure and routine, whether itââ¬â¢s brushing their teeth or bedtime rituals. School-aged children, on the other hand, require more independence and trust in decisions while still being guided and reassured as the develop their own sense of identity. There are similarities as amongst the age groups as well, such as all of the children moving towards a state of autonomy and the ability to express themselves adequately and be heard by either their parents, their peers, or both. Additionally, all of the different age groups have the need for a structured and healthy home environment in order to grow and develop. 2) Summarize how a nurse would handle physical assessments, examinations, education, and communication differently with children versus adults. Consider spirituality and cultural differences in your answer. When the nurse is caring for a child, the nurse must remember that they are essentially caring for the child and the parent (Jarvis, 2012). For a nurse, the assessment, examination and interaction with a child patient offers its own set of challenges and requires a different approach from that of an adult. When dealing the toddler and preschooler, the nurse should visit with the parent first, letting the child size the nurse up. The nurse can assess child on how they interact and react to the parent and the nurse. This allows the child to see that the caregiver has accepted and trusts the nurse. For the toddler and the preschooler, the parent will be providing most, if not all of the health history. When beginning the physical assessment on the child, move slow and approach them slowly while seeming happy and unthreatening. The nurse should allow the child to hold instruments, like a stethoscope, during the physical exam to help them feel like they are involved in their own care. Having parents there add security and support for children, and also can help with the ease of assessing theà child without them realizing that they are being assessed. With children of each stage of development, the nurse must be cognizant of verbal and non-verbal cues provided by the child. The nurse should be mindful that there could be cultural and/or spiritual considerations to take into account, like when undressing a child of the opposite sex. The nurse needs to ensure that the caregiver and the child feel comfortable. With both children and adults, assessment should start with least invasive and progress leaving most invasive last. School-Age children should be assed like either children or adults depending on their developmental age. Adult assessment can be more direct than that of a child. Ask adults open ended questions, listen to their complaints, and educate as needed. References Current Nursing. (2012). Theory of Psychosocial Development: Erik H. Erikson.

Terror in Small-Town, USA :: Example Personal Narratives
Terror in Small-Town, USA Situated between the lush green rolling hills, is Small-Town, USA. It was election day, and looking forward to a visit to the ice cream shop, I accompanied my grandfather as he drove the ten-mile journey to town. Country life offered little excitement, but that day an air of uneasiness replaced the usual contentment one felt while passing aged buildings, their drabness contrasted sharply by a few colorful, modern improvements. Having spent the first ten years of my life here, it was easy to detect any change in the town's mood. I pondered the worried expression on the faces of the few people we saw on the streets. It seemed everyone was in a hurry. There were not the usual groups gathered to exchange local gossip. Most noticeable was the absence of children. As my grandfather's dilapidated Ford approached the town's only traffic light, we were greeted-not by flashing red, yellow or green--but by uniformed National Guardsmen armed with guns and appearing much out of place in such placid surroundings. As our vehicle slowed to a stop, I was aghast as I saw before me a huge machine gun, pointed in our direction. A young guardsman walked briskly to the car and explained, almost apologetically, "Sorry Sir, but we'll have to search your car. Just routine procedure." As the car was being searched, we learned the reason for such drastic precautionary measures. A man whom we knew and who was a candidate for the sheriff's office, had been brutally murdered in the presence of his wife and daughter. It was rumored that the opposing party was responsible for the fatal shotgun blast, and other rumors stated that explosives would be brought into town to bomb the courthouse. As this unbelievable information was being given, I sat petrified, trying to convince myself that this was the same town where, only yesterday, old men in dirty overalls lounged around the courthouse, spitting tobacco and discussing the forthcoming election. Dogs and children had romped freely on the sidewalks, while women browsed in the stores for hours without buying anything. Strangely, all this had changed overnight, and the preconceptions I had about our peaceful country and the glorious right to vote were beginning to sound as a sour note.

Proposal for Reparations of African Americans Essay
Due to the fact that many African-Americans cannot trace their genealogy back more than three generations, It would be extremely difficult to distinguish between those who are descended from Freemen and those descended from Slaves. Therefore, although it should have some impact on reparations, we must take into account those who cannot trace their genealogy( approximately 3/4th of African- Americans). We also must remember that in essence, no African-Americans were completely free. Many blacks, Freeman and Slaves alike were lynched, falsely imprisoned, raped, murdered, and subject to sub-human treatment. It is almost impossible to estimate the economic hardship caused by slavery and the aftermath that followed. To this day the African-American family still suffers from the aftermath of slavery. We see it in the form of Poverty, under-education, Discrimination, and Black on Black crime. Consider that Blacks are seriously under-represented in many of our nations top fields. Less than .05 percent of African-Americans are CEOââ¬â¢s in corporate America. Blacks are also a rarity in Law, Medicine, and higher education, What follows is my estimation of the reparations needed. 1st generation descendant of slave: 500,000 of Freeman: 350,000 2nd generation descendant of slave: 350,000 of Freeman: 225,000 3rd generation descendant of slave: 225,000 of Freeman: 180,000 4th generation descendant of slave : 180,000 of Freeman: 120,000 5th generation descendant of slave: 120,000 of Freeman: 90,000 6th generation descendant of slave: 90,000 of Freeman: 60,000 7th generation descendant of slave: 60,000 of Freeman: 30,000. Additional Moneys. Family member lynched: 60,000 per family Family member raped by slave master: 20,000 Family member falsely imprisoned: 6,000 It is important to note that in the event that it cannot be determined whether a family descended from Freemen or Slaves, an average should be taken from the two. Also, in the event that a generation has no living survivors, that money shall not be awarded and is not subject to inheritance. As for Moneys for family menders lynched, raped, or falsely imprisoned, this must be a direct result of slavery and most be proven beyond a preponderance of the evidence. Therefore, each state shall appoint a committee of six members, at least three of them being African-Americans. These committees will be responsible for investigating all claims on an individual basis and awarding money. If, for example, a member of the 3rd generation starts a claim and dies before the moneys are awarded than that money shall be subject to inheritance. The committee will have a period of five years to investigate and award all moneys. In the event that a family wants to appeal their award or lack there of, their claims shall be directed to the State supreme court. The court will have three years to render decisions on all claims. In order to ensure the financial stability of the United States, these payments shall be made over a period of 15 yrs. However, in the case of persons who have been awarded moneys and are over the age of 55, they will have the option of taking a discounted lump sum of 40% of the moneys owed.

Macbeth Hallucinations
Desires of the Subconscious In the tragedy, Macbeth, William Shakespeare uses motifs as a way to portray several different underlined themes of his work. Of the numerous themes, one in particular is applied throughout the entire story, this motif being hallucinations. Even while mans conscious is actively thinking, his subconscious is also thinking. It is thinking about the true desires of ones heart. The subconscious also thinks about guilt and what it wants to forget about. These two ideas of the subconscious come alive in this tragedy through hallucinations.In the beginning of the tragedy, Macbeth receives a prophecy that he will become king. His aspiration for becoming king clouds his conscience. He desires to become king so much that he and Lady Macbeth create a plan to murder Duncan and take his power. While they are carrying out the plan, Macbeth sees something in front of him. This is further shown in the quote, ââ¬Å"Is this a dagger which I see before me. the handle toward my hand? Come, let me clutch thee. I have not, and yet I see thee still.Art thou not, fatal vision, sensible To feeling as to sight, or art thou but A dagger of the mind, a false creation, Proceeding from a heat-oppressed brain? â⬠(2. 1. 33-39) This hallucination is particularly interesting. At this point in the tragedy, Macbeth is having second thoughts about murdering Duncan. As he hallucinates of a bloody dagger pointing towards Duncanââ¬â¢s room, it shows the reader that he is yearning to become king so badly that he would murder for it. Though the reader doesnââ¬â¢t see this from Macbethââ¬â¢s exterior emotions, it is depicted through his subconscious.In the next act, Macbeth kills his best friend, Banquo, because he is becoming suspicious of the murder. Shakespeare shows Macbeth growing guilty of this act through another illusion in the quote, ââ¬Å" If I stand here, I saw himâ⬠¦ Blood hath been shed ere now, iââ¬â¢ thââ¬â¢ olden time, Ere humane sta tue purged the gentle weal; Ay, and since too, murders have been performed Too terrible for the ear. The time has been and there an end. But now they rise again With twenty mortal murders on their crowns And push us from our stools. This is more strange Than such a murder is. (3. 4. 89-99) As the story continues, Macbeth feels more and more guilt building up on him. This guilt persuades his subconscious to form a mirage of Banquo, arriving to dinner with him. This shows the reader that Macbeth is feeling overwhelming guiltiness. As Lady Macbeth played a large role in the murders of Duncan, Banquo and Macduffââ¬â¢s family, she is also being plagued with guilt. This is shown when she is sleep walking in the following quote, ââ¬Å"Here's the smell of blood still. All the perfumes of Arabia will not sweeten this little hand.Oh, oh, oh! â⬠(5. 1. 49-51) In this quote, the blood that Lady Macbeth sees on her hands represents guilt. The hands represent her mind. Therefore, Lady Ma cbeth canââ¬â¢t disguise her guilt in anyway so much as to say that all of the perfumes of Arabia cannot overpower the guilt she feels. Shakespeare uses the motif of hallucinations to illustrate the theme that what man hallucinates is what man either wants to see or what he wants to forget about. This is shown in Macbeth before the murder of Duncan, after the murder of Banquo and at the end of the book.

The Need to Care for the Environment Essays
The Need to Care for the Environment Essays The Need to Care for the Environment Paper The Need to Care for the Environment Paper Whether the issue is air pollution, endangered species, re-cycling, or clean water, all environmental scientists, educators, and policy-makers agree that the key to public understanding is public education. Without a thorough understanding of the problems facing the planet in terms of its fragile environment, humanity is on a collision course with disaster. It is not enough to warn people, impose economic sanctions, and establish strict regulations. People must understand why they should recycle, how they can take care of their waste, and what they can do to lessen their own individual impact on the earth. It is also essential that environmental education be appropriate and applicable to the person doing the learning. Too often, environmental education focuses on a topic far removed from the reality of the student. A child living in the mountains can have all the concern in the world for the manatee or the blue whale and be completely unaware of the forest degradation going on in her own mountain backyard. Likewise a Brentwood student can be vitally concerned about the nuclear waste dumps in the desert but still mindlessly damage her own unique environment. In order for environmental education to be truly effective it must be both relevant and applicable. Such awareness may be the only truly viable option that exists that can make a difference in saving or renewing the earths rapidly diminishing natural resources. Such education must be fully integrated so that the student can understand the interrelatedness of all aspects of the environment, including her role within it. Once a person understands that all life on earth, not just human life, is dependent on the health and protection of the environment, it is no longer possible to dismiss the planet as a nothing more than an object designed to meet human needs and desires. The most valuable time to begin such environmental education and awareness is with teenagers while they have not yet lost their sense of connection to all that surrounds them. In order to best communicate the importance of the environment and the need to care for it as vigilantly as human beings care for themselves, students must begin to learn at an early age to respect the earth, its environment and all of its inhabitants. The environment is not some abstract concept. That lesson must continue to be taught and learned throughout life in order to facilitate meaningful change. Each individual must understand the consequences of her actions on the surrounding environment, whether it is in a rural area or city. Teenagers are, admittedly, creatures of self-interest but certainly there can be no greater service to oneself than the assurance that there is clean air to breathe, fresh water to drink, healthy food to eat or sanitary housing. The foundation and encouragement of that self-interest is education. Beginning in the first years of school, children are taught the processes of life on this planet. Even very young kids can easily understand that a strong plant cannot grow in unhealthy soil or that trash does not simply disappear. There can be no more valuable lesson than how to not poison oneself through unthinking or greed-based actions. Active recycling is genuinely a better lesson than algebra and living more simply in the midst of a consumer-driven society is undeniably more useful than memorizing the dates of battles long since fought. Environmental education can and does make a difference and is a valuable ideal for the future.

Change Detection Techniques of Remote Sensing Imageries
Change Detection Techniques of Remote Sensing Imageries 1.1 Introduction Over the past years, academics have suggested enormous numbers of change detection techniques of remote sensing imageries and classified them from a different point of views [ 28 ]. These techniques depend on the assumption of spatial independence among pixels. This assumption is valid only for low, medium and high-resolution images but insufficient for VHR images [ 1 ]. This chapter presents the concept, implementation, and assessment of seven change detection techniques using low, medium and high-resolution ORSI. The rest of this chapter is organized into eight sections. Section 3.2 presents a brief description of the study areas. Section 3.3 describes the dataset characteristics of the study areas (Sharm El-Sheikh city and Mahalla al-kubra city ââ¬â Egypt). Section 3.4 presents the pre-processing performed on the image dataset before change detection process. Section 3.5 provides the accuracy assessment measures used for evaluation of the change detectio n process. Section 3.6 illustrates the concepts of the selected seven change detection techniques . These techniques are post-classification, direct multi-date classification (DMDC), image differencing (ID), image rationing (IR), image symmetric relative difference (ISRD), change vector analysis (CVA), and principal component differencing (PCD). Section 3.7 presents the experimental work. It explains the Implementation and accuracy assessment of applying the selected change detection techniques on an image dataset of Sharm El-Sheikh city- Egypt. Section 3.8 presents the application of ââ¬Å"post-classificationâ⬠change detection technique on an image dataset of El-Mahalla El-kubra City-Egypt to detect the urban expansion over the agricultural area through the period from 2010 to 2015. Finally, section 3.9 gives the chapter summary. 1.2 The study areas In this chapter, two study areas are selected for the application of the selected change detection techniques. The first area is a part of Sharm el-Sheikh city. It is located on the southern landfill of the Sinai Peninsula, in the South Sinai Governorate, Egypt, on the coastal bar along the Red Sea as shown in figure (3.1). Its population is approximately 73,000 as of 2015 [ 62 ]. Sharm El Sheikh is the administrative hub of Egyptââ¬â¢s South Sinai Governorate, which includes the smaller coastal towns of Dahab and Nuweiba as well as the mountainous interior, St. Catherine and Mount Sinai. Today the city is a holiday resort and significant center for tourism in Egypt. The selected area is about 12.5 Km 2 . The second study area is a village belongs to El Mahalla El Kubra city. El Mahalla El Kubra is a large industrial and agricultural city in Egypt, located in the middle of the Nile Delta on the western bank of the Damietta Branch tributary, as shown in figure (3.2). The city is known for its textile industry. It is the largest city of the Gharbia Governorate and the second largest in the Nile Delta [ 63 ]. The selected area is about 38 Km 2 . 1.3 Images datasets of the study areas In this chapter, two datasets are used. The first dataset consists of two images of Sham el-Sheikh city acquired by Landsat 7 at 2000 and 2010 respectively as shown in figure (3.3). Area of the image lies between Lat. 28 0 37.0091 N, Lon. 34 17 56.3381 E and Lat.à 27 57 20.8804 N, Lon. 34 24 43.6080 E. Table (3.1) summarizes the characteristic of these images.

It is taken by El-Shayal Smart web online Software that could acquire Satellite images from Google Earth. The image area lies between Lat. 30 57 46.9032 N, Lon. 31 14 35.4776E and Lat. 30 54 47.00 N, Lon. 31 18 19.98. Table (3.2) summarizes the characteristic of this dataset.

The execution of preprocessing on the dataset used is given in section 3.7.2. 1.4.1 Radiometric correction Radiometric conditions are influenced by many factors such as different imaging seasons or dates, different solar altitudes, different view angles, different meteorologic conditions and different cover areas of cloud, rain or snow etc. It may affect the accuracy of most change detection techniques. Radiometric correction is performed to remove or reduce the inconsistency between the values surveyed by sensors and the spe ctral reflectivity and spectral radiation brightness of the objects, which encompasses absolute radiometric correction and relative radiometric correction [ 26 ]. Absolute radiometric correction It mainly rectifies the radiation distortion that is irrelevant to the radiation features of the object surface and is caused by the state of sensors, solar illumination, and dispersion and absorption of atmospheric etc. The typical methods mainly consist of adjusting the radiation value to the standard value with the transmission code of atmospheric radiation, adjusting the radiation value to the standard value with spectral curves in the lab, adjusting the radiation value to the standard value with dark object and transmission code of radiation, rectifying the scene by removing the dark objects and so on. Due to the fact that it is expensive and impractical to survey the atmospheric parameter and ground objects of the current data, and almost impossible to survey that of the histor ical data, it is difficult to implement absolute radiometric correction in most situations in reality. Relative radiometric correction In a relative radiometric correction, an image is regarded as a reference image. Then adjust the radiation features of another image to make it match with the former one. Main methods consist of correction by histogram regularization and correction with fixed object. This kind of correction can remove or reduce the effects of atmosphere, sensor, and other noises. In addition, it has a simple algorithm. So it has been widely used. The radiation algorithms that are most frequently used at present in the preprocessing of change detection mainly consists of image regression method, pseudo-invariant features,à dark set and bright set normalization, no-change set radiometric normalization, histogram matching, second simulation of the satellite signal in the solar spectrum and so on. It should be pointed that radiometric correction isnââ¬â¢t n ecessary for all change detection methods. Although some scholars hold that radiometric corrections are necessary for multi-sensor land cover change analysis Leonardo studies at 2006 have shown that if the obtained spectral signal comes from the images to be classified, it is unnecessary to conduct atmospheric correction before the change detection of post-classification comparison. For those change detection algorithms based on feature, object comparison, radiometric correction is often unnecessary [ 64 ]. 1.4.2 Image registration Precise registration to the multi-temporal imageries is essential for numerous change detection techniques. The importance of precise spatial registration of multi-temporal imagery is understandable because generally spurious results of change detection will be formed if there is misregistration. If great registration accuracy isnââ¬â¢t available, a great deal of false change area in the scene will be caused by image displacement. It is commonly approved that the geometrical registration accuracy of the sub-pixel level is recognized. It can be seen that the geometrical registration accuracy of the sub-pixel level is necessary to change detection. However, it is doubtful whether this result is suitable for all registration data sources and all detected objects and if suitable how much it is. Another problem is whether this result has no influence on all change detection techniques and applications and if there is any influence how much it is. These Problems are worth to be studied further. On the other hand, it is difficult to implement high accuracy registration between multi-temporal especially multi-sensor remote sensing images due to many factors, such as imaging models, imaging angles and conditions, curvature and rotation of the earth and so on. Especially in the mountainous region and urban area, general image registration methods are ineffective and orthorectification is needed. Although geometrical registration of h igh accuracy is necessary to techniques used for low, medium and high resolution (like image differencing techniques and post-classification), it is unnecessary for all change detection t. For the feature-based change detection methods like object-based change detection method, the so-called buffer detection procedure can be employed to associate the extracted objects or features and in this manner, the harsh prerequisite of perfect registration can be escaped [ 65 ]. However, these methods neglect the key problem of the distinction between radiometric and semantic changes. So, it does not address the problem of change detection from a general perspective. It just focuses on specific applications relevant to the end user [ 1 ]. 1.5 Accuracy Assessment used for Change Detection Process evaluation The accuracy of change detection depends on many factors, including precise geometric registration and calibration or normalization, availability and quality of ground reference data, t he complexity of landscape and environment, methods or algorithms used, the analystââ¬â¢s skills and experience, and time and cost restrictions.à Authors in [ 66 ] summarized the main errors in change detection including errors in data (e.g. image resolution, accuracy of location and image quality), errors caused by pre-processing (the accuracy of geometric correction and radiometric correction), errors caused by change detection methods and processes (e.g. classification and data extraction error), errors in field survey (e.g. accuracy of ground reference) and errors caused by post-processing. Accuracy assessment techniques in change detection originate from those of remote sensing images classification. It is natural to extend the accuracy assessment techniques for processing single time image to that of bi-temporal or multi-temporal images. Among various assessment techniques, the most efficient and widely-used is the error matrix [ 26 ]. It describes the comparison or cr oss-tabulation of the classified land cover to the actual land cover revealed by the sample sites results in an error matrix as demonstrated in the table (3.3). It can be called a confusion matrix, contingency table [ 67 ], evaluation matrix [ 68 ] or misclassification matrix [ 69 ]. Different measures and statistics can be derived from the values in an error matrix. These measures are used to evaluate the change detection process. These measures are overall accuracy, procedures accuracy and user accuracy [ 70 ]. Overall accuracy of the change map It presents the ratio of the total number of correctly classified pixels to the total number of pixels in the matrix. This figure is normally expressed as a percentage. It can be expressed as follows: The overall accuracy = à à à à à à à à à à à à à à à à à à à à à à (3.1) Userââ¬â¢s accuracy (column accuracy) It is a measure of the reliability of change map generated fro m a CD process. It is a statistic that can tell the user of the map what percentage of a class corresponds to the ground-truthed class. It is calculated by dividing the number of correct pixels for a class by the total pixels assigned to that class. The user accuracy = à à à à à à à à à à à à à à à à à (3.2) Producerââ¬â¢s accuracy (raw accuracy) It is a measure of the accuracy of a particular classification scheme. It shows what percentage of a particular ground class was correctly classified. It is calculated by dividing the number of correct pixels for a class by the actual number of ground truth pixels for that class. The procedure accuracy = à à à à à à à à à à à à (3.3) Table ( 3 . 3 ) Change error matrix or confusion matrix. Classified land cover Actual land cover Class1 = change Class2 = no change Class1 = change Correct False Class2 = no change False Correct 1.6 Concepts of the selected change detection techniques Seven LULC change detection techniques are selected to be implemented on our dataset. These techniques are post-classification, direct multi-date classification ( DMDC ), image differencing (ID), image rationing (IR), image symmetric relative difference (ISRD), change vector analysis (CVA), and principal component differencing (PCD). Image differencing Itis based on the subtraction of two spatially registered imageries, pixel by pixel, as follows: ID =X i (t 2 ) ââ¬â X i (t 1 )à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à à (3.4) Where: X represents the multispectral images with I (number of bands) acquired at two different times t 1 and t 2 . The pixel s of changed area are predictable to be scattered in the two ends of the histogram of the resulting image (change map), and the no changed area is grouped around zero as shown in figure (3.5). This simple manner easily infers the resulting image; conversely, it is vital to properly describe the thresholds to perceive the change from non-change regions [ 71 ] . Image Rationing It is similar to image differencing method. The only difference between them is the replacement of the differencing images by rationed images [ 71 ].

Unit 2 Bus Assignment Example | Topics and Well Written Essays - 250 words
Unit 2 Bus - Assignment Example This is useful in enhancing a studentââ¬â¢s problem solving skills and allows them to engage in relevant and related discussions with classmates and professors (Ronstadt, 2004). For the purpose of paper I will write on the additional insight gained in relation to Hill and Jones book, specifically analyzing a case study. According to Hill & Jones, a case study offers a suitable way to examine how a companys past policy and configuration influence it in the present and to chart the critical incidents in its history that is, the events that were the most unusual or the most vital for its development into the company it is at present (2013). Some of the events have to do with its naissance, how it makes new product market decisions, and its initial products. It could also revolve around how it developed and chose functional strong points to pursue. Its shifts in its main lines of business and entrance into new businesses are also important milestones to consider. Identifying the companys internal strengths and weaknesses is also important because once the historical outline is completed; one can commence to the SWOT analysis. It is necessary to use all the incidents that have been charted to come up with an report of the companys strengths and weaknesses as they have unfolded historically (Ronstadt, 2004). An important aspect of case analysis is to examine each of the value creation functions of the company, and identify the functions in which the company is currently strong and currently weak. Some companies might be weak in promotion; some might be strong in research and development. A case analysis makes lists of these strengths and weaknesses (Hill & Jones, 2013). A case analysis also makes use of financial ratios for the purpose of financial analysis. According to Hill and Jones, a quality case analysis is that which offers a well thought analysis of the
