Comparison between traditional and online casses Essay
Comparison between traditional and online casses - Essay Example Online classes are gaining prominence in the contemporary world, where there is more favor towards them than traditional classes.In these two types of rather forms of classes,there are certain differences and similarities that set them apart and bring them together respectively,and as a result,there is a need to look into these aspects of the two types of classes. There are a number of distinct similarities and differences between traditional and online lessons, where online lessons provide flexibility, which is only one of the largest advantages of learning or taking lessons online. In online lessons, the flexibility that students have is that it allows them to attend classes at their own convenience, when they have the time, and when they can concentrate without any distractions. In addition to this, there is the flexibility of taking online lessons at one own time when the student is travelling or taking art in other activities simultaneously. This is unlike traditional lessons or classes, where students have fixed schedules to attend classes at the prescribed time rather than attending lessons at their own convenience. However, there is a similarity in this case between the two in that the convenience of flexibility is almost similar in that most schools allow lessons to miss traditional classes when it is not entirely convenient to attend them. This is in cases of severe illness or other emergencies, which makes both traditional and online classes conveniences. ... In these cases, online learning becomes distinct from traditional learning, as learners have to wait for some time to receive feedback, especially in cases where they use email for communication. Students are unable to get direct instruction and immediate feedback, which at times affects performance due to clarity of instruction. On the other hand, traditional learning in the classroom allows students to have immediate feedback from their instructors, which increases motivation for the learners and even simplifies difficult concepts in technical courses and units such as statistics (Stevens and Switzer 97). This is in addition to difficulty in expressing ideas and contributing positively in the learning experience in online lessons because traditional lessons go contrary to this by allowing immediate contribution when called upon by the instructor. Interaction Traditional classroom interaction offers a rich social experience for learners, where they get to interact with one another b eyond conventional academic means, as found in the case of online lessons. In traditional classroom lessons, learners can meet their classmates and exchange ideas on their academic performance and other social aspects bringing them together as a social unit. Although online learning has an interaction platform in the form of chat rooms, through which students post discussion topics and exchange ideas, but they are unable to go beyond these and into the social realm of interpersonal relationships. This serves as both a similarity and a difference between traditional lessons and online lessons where learners can interact, but only through different

Insulin-Dependent Diabetes Mellitus - Essay Example (Condition: Insulin dependent Diabetes mellitus, 2008) Specifically, in type 1 diabetes, the beta cells of the pancreas produce little or no insulin, the hormone that allows glucose to enter body cells. This glucose serves as the source of energy in the body, when this hormone is not produced the cells does not gets adequate energy to perform the activities. When enough insulin is not present, the body is not able to use glucose as source of energy. The body is unable to use this glucose for energy despite high levels in the bloodstream, leading to increased hunger. (Condition: Insulin dependent Diabetes mellitus, 2008) Moreover, the high levels of glucose in the blood lead to more urination in the patient and further also lead to excessive thirst. Not more, within 5-10 years most of the beta cells are destroyed and the body no more produces insulin. (Diabetes, 2005) Type 1 diabetes can occur at any age, but it usually starts in people younger than 30. Symptoms are usually severe and occur rapidly. The cause of the insulin dependent diabetes mellitus is unknown, but some research shows a viral infection may play a positive role where is causes destruction of f the insulin secreting tissues that often lead to inflammation of the pancreas. It is also reported that there are some genes responsible for causing this disease, but the pattern of inheritance is complicated. The child of a person who has insulin dependent diabetes mellitus is at a greater risk of developing the same type of the disease. But, most of the children affected with IDDM have parents who are not already affected with IDDM. Dietary measures can be used to help control the disease, but it also must be treated with insulin injections. (Condition: Insulin dependent Diabetes mellitus, 2008) The symptoms leading to IDDM develop quickly and very severe. Some of the symptoms are listed below: 1. Frequent Urination; 2. Unusual Thirst; 3. Extreme hunger; 4. Usual weight loss; 5. Extreme fatigue; 6. Irritability; 7. Nausea; 8. Vomiting; 9. Confusion; 10. The smell of the breadth is like acetone. (Condition: Insulin dependent Diabetes mellitus, 2008). If the patients encounter symptoms above then he or she should consult a doctor. The diagnosis that the doctor will perform will be doing a physical exam and some laboratory blood tests. The doctor will also work upon the optimum insulin dosage to treat hyperglycemia (high blood pressure). The dose of the insulin depends on person to person and will vary with period of time. The calorie intake will also be discussed and the amount of insulin will be panned with physical activity that will be required to reduce the blood glucose level and the thus the need of the insulin. (INSULIN DEPENDENT DIABETES MELLITUS (IDDM). Other tests like urinalnyis, glucose tolerance test, Fasting blood glucose and Glycosylated hemoglobin AIC level can also be performed. If the patient is suffering from any eye problems or any problems that involves problem with vision than operation will also be performed. Other complications might include gangrene and coronary heart disease. (INSULIN DEPENDENT DIABETES MELLITUS (IDDM). A vitamin D dose of 2000 IU per day is given during the first year of a child's life in Northern Finland because it is believed that there is a reduction of getting Type 1 diabetes latter in life, and the

International Relations Research Paper Example | Topics and Well Written Essays - 750 words
International Relations - Research Paper Example In fact, it ââ¬Å"refers both to a process of growing material interconnectedness as well as to the ââ¬Ëideaââ¬â¢ or consciousness of that processâ⬠(Ravenhill 302). The purveyor or enforcer of such idea is the WTO. Although the WTO is supposedly a consensual type of organization, where the majority, which consist of the underdeveloped and developing countries, is theoretically the more powerful group, it is actually the few developed and advanced capitalist countries that are most influential in the formulation of its policies. Since its founding, the WTO has been accused of making the economic conditions of the poorer nations worse. According to Global Exchange, an international human rights advocacy organization, the WTO has made the worldââ¬â¢s richest become richer at the expense of the poorest as it has ââ¬Å"hastened these trends by opening up countries to foreign investment and thereby making it easier for production to go where the labor is cheapest and most easily exploited and environmental costs are lowâ⬠(Top Reasons to Oppose the WTO). The WTO was established in January 1995. However, the basic principles behind it were already being implemented since 1948 through the General Agreement on Tariffs and Trade or GATT (World Trade Organization). ... However, there are developing countries with governments that have continued to adhere to the policies of the WTO despite the massive protests that have been held in their respective countries. Behind these are the corporations who have accumulated profits because of globalization (Berberoglu 68). Since the WTO regularly meets in order to discuss the implementation of trade liberalization, the agendas that it often tables are scrutinized by different peopleââ¬â¢s organizations. One contentious issue that has been the subject of intense protest campaigns from farmers is agricultural liberalization. The WTO calls for ââ¬Å"the removal of exemptions for import controls and supply management regimesâ⬠(Shrybman 50). The net effect of this policy is that a less developed nation that could not compete well can be dumped with agricultural products coming from the more developed countries. This naturally puts the farmers of the said country at a grave disadvantage because of unfair competition resulting from it. With inadequate subsidy, the farming sector of the less developed country would certainly not be able counter the heavy importation. Another major criticism of the WTO is that it tends to ignore the impact of its policies on other important aspects of society. It is said that in every forum that is held by this multilateral body, ââ¬Å"global commerce takes precedence over everything ââ¬â democracy, public health, equity, the environment, food safety and moreâ⬠(Wallach & Sforza 20). There are two other issues that have been consistently raised against the WTO; these are on matters of the environment and labor. When it comes to the environment, there have been calls by environmental groups to use trade sanctions as a means to pressure erring nations to comply with

Teens Marriage Essay Example for Free
Teens Marriage Essay People under the age of eighteen should not be allowed to get marry, because at the end of the day theyââ¬â¢re still teenagers. Even though they are young adults, they still donââ¬â¢t get the meaning of being married and I dont think they would be mature enough to take that responsibility, their mentality is not ready yet to play that role. Many young adults marry so young because of various reasons. Numerous of teenagers get marry because of pregnancy. However, itââ¬â¢s almost never the case of marrying someone because of love, which is the way many marriages should be based on. Sadly it is not. Pregnancy is the most common reason why young adults get married so young. Some guys feel that if they get their girlfriend pregnant, that itââ¬â¢s their job to take care of their responsibility, which should never be the case. If you and your boyfriend/girlfriend are not ready to take the big step by getting married and supporting each other, then you should never feel that itââ¬â¢s what you have to do for the baby. It will only cause more confusion for the kid. A seventy percent of this kids, when their parents get divorced they end up doing something bad, like getting into drugs or alcohol. So its way better if you donââ¬â¢t get married at a young age. Todayââ¬â¢s generation of young adults live their lives so differently. In the United States, half of teen marriages dissolve within fifteen years of the marriage. The reason of this is because many young adults jump right into marriages without any experience. For instance, Iââ¬â¢m pretty sure that when teenagers under the age of twenty get married their usually just leaving their parents care and arenââ¬â¢t use to taking care of themselves as far as paying bills, groceries, car insurance and other things that come along with being a responsible adult. When you move out and get married things change. If you want to be supported by your spouse then you have to do the same. Never jump right into a marriage if youââ¬â¢re not ready, itââ¬â¢s only going to make the marriage worst and it will end earlier than you had anticipated on. As a conclusion, there is an overwhelming body of evidence to demonstrate that marriages between young partners simply do not last. At 16, you cant drive, vote, serve actively in the Army, drink or buy cigarettes. Clearly, someone who is not of an age to be given full responsibility for their life should not be encouraged to marry and start a family. We need to accept that teens, whilst being normally sexually active, are simply not mature enough to marry. This is why I think that people under the age of eighteen should not be allowed to get marry.

Overview Of Data Structures And Algorithms Computer Science Essay
Overview Of Data Structures And Algorithms Computer Science Essay As Robert Lafore has stated, data structures are a collection of structures that are used to store data in a memory location. A Data structure is designed to organize data to fulfill ones purpose of accessing and using them. Arrays, linked lists, stacks, binary trees, and hash tables etcThese are included as data structures. But there are data structures that can be thought of as Abstract data types as well, the given examples above can be considered as ADTs except arrays. All most all data structures have both advantages and disadvantages. Nell B.Dale et al (1996) has stated that an abstract data type is one whose set of operations that are defined in a certain level without getting any restrictions from operational details. According to Robert Lafore (2008) An Abstract data type is a way of looking at a data structure simply focusing on what it does instead of focusing on how it does it. Both of these definitions give a similar meaning. If taken from Nell Dales point of view its a set of operations in a certain level that has no restrictions by operational details on it. When compared this definition with Robert Lafores definition, An Abstract data type is a way of looking at the operations of the data structure and as Nell Dale stated in the end without getting any restrictions by operational details. By operational details Nell Dale has meant it does not focus on how on the details of those operations. In conclusion to both these definitions, an abstract data type is a logical operation on certain level of data structures focusing on its process and not its method. Stacks and queues are examples of ADTs. .Classification of data structures Arrays Robert lafore has explained Arrays to be known as the most commonly used data structure in programming. An array is a series of elements that is of the same type and same name. It is possible to create an array of any data type. In order to access an array the array has to have an index. An index is an integer that allows access to each of the elements of an array. Using an array we can name a group of elements instead of naming each of them individually. A simple array will look like this see FIGURE 1.2.1 Data Index FIGURE 1.2.1 a simple array The data within the array are the data entered to an array. And the numbers below outside the array are indexes used to access the particular data packet. Advantages Quick insertion Very fast access if index is known Disadvantages Slow search Slow deletion Fixed size Stacks A stack is special a kind of a list in which both insertion and deletion takes place from the top of the stack. To add new elements to a stack a word called push is used instead of insert and for removal or deleting of an element the word pop is used. Robert lafore(2008) has stated that a stack allows access to only one data item at a time. This is because a stack provides a LIFO or Last in first out method. This means the last data item that is pushed into a stack is the first item that will be popped. Then it provides access to the next data item and so on. By the name of this data structure itself it gives a picture of how the data structure would be. Given an example, a stack of data blocks, the last data block to be entered gets removed first. See FIGURE 1.2.2 Insertion of new data item takes place on top Deletion of item takes place on top Stack of data blocks 30 30 1 1 1 24 24 24 5 5 5 14 14 14 16 16 16 FIGURE 1.2.2 a stack of data blocks Advantages Provides last in first out access Disadvantages Slow access to other items Queues This is a data structure of ordered elements in which insertion takes place at the end and deletion takes place at the front. A queue is a known as a FIFO or first in first out. Unlike stacks in queues the first data item to be entered is removed from the queue first. The process of a queue is easy to understand when modeled to the real world. For example think of the line ups in your local grocery stores. Each of the customers waits in line and one at the front of the line get to go first. Each of the new customers joins the line in the rear. See figure 1.2.3 New customers join at the end of the queue First customer joins the queue, first to go FIGURE 1.2.3 A queue of customers Similar to the figure 1.3 above in computer science the elements which are inserted first in a queue are removed first from the queue. Advantages Provides first in first out access Disadvantages Slow access to other items Linked lists Linked list has a similarity with arrays. D.Samanta (2004) has defined that linked lists as a ordered collection of finite, adjacent data elements called as nodes where linear order is maintained by links or pointers. Links or pointers are used to address to the other node. Simplify by pointing to the next location in the sequence. The pointers are maintained depending on the requirements. FIGURE 1.2.4 shows a simple example of a linked list. Link Link to the next node node Data FIGURE 1.2.4 a simple linked list Advantages Quick insertion Quick deletion Disadvantage Slow search 1.3. Importance of data structures in software industries Importance of data structures To understand the importance of data structures first we have to know what data structures are. It is already explained in the previous sections. What is the importance of it? The importance is that a data structure can give an overview of the types of operations that can be performed and its processes. In a software industry Software industries keep changing and growing continuously, which requires a great deal of innovative ways to solve the problems they face. Use of data structures can bring down the stress level down to a point. Because uses of data structures are most effective if the programmers know what he wants to do with the data, whether he wants random access or the ability to move back and forth through the data. Use of data structures helps the programmer to determine which data structure has to be used in which situations. It is very important that the data are stored in a way that it can be retrieved and accessed easily in the future. Data structures fulfill this importance. According to Robert Lafore (2008) data structure is nominated among three categories where it is useful. Real- world data storage Programmers tools Real-world Modeling These three categories help understand the usefulness of data structures. By real-world data storage it means data is described based on physical entities like personnel records that describe a human, here the data is personnel records and entity is human. Programmers tools are meant to be accessed only by the program itself. Because this is entirely based on the data storage structures that are not meant to be accessed by the user. Stacks, queues, and priority queues are tools that a programmer uses in such a way to facilitate some other operations. Last but not the least its real-world modeling. It is basically structures that model real world situations. The most important data structure of this type is graph. Graphs can be used to represent airlines routes between cities etcà ¢Ã¢â ¬Ã ¦ Based on these three categories alone, we can point out that data structures provide a vast area in which data structures can be helpful for development of software industries. 1.4. Complexity in relevant to data structures When using data structures there is an important aspect related to them called as algorithms. Robert Lafore (2008) has defined that algorithms are used to manipulate the data within the data structures. Algorithms can be used in various ways, for searching particular data items and sorting the data. Shi kuo chang has stated that the concept of an algorithm is one of the most important elements of computer science. Because its useful to frame a problem and get solutions without any errors. When it comes to algorithms there are two complexities that arise from it, Time complexity and space complexity. Time complexity As Alfred V Aho et al (2009) has explained the time needed by an algorithm given as a function of the problems size is called as the time complexity. There are three cases in time complexity best case, average case and worst case this can be explained separately in relevance to data structures. Best case: This is when an algorithm takes minimum amount of time to search a desired set of inputs. For an example you can take a stack when searching for an element in a stack with a Linear search if u come across the element you are looking for at the top of the stack then it can be called as best time complexity. Average case: Average time complexity is the mean number of operations assuming the probability of the input. The binary search method in algorithm can be identified as an average case time complexity method. Worst case: If an algorithm takes maximum amount of time to find the desired set of inputs then its called a worst case time complexity. For an example you can take a stack again when searching for a desired element using a linear search if it is at the bottom of the stack then it is a worst case time complexity. Space complexity According to Alfred V Aho et al (2009) space complexity determines the size of the problems that can be solved by an algorithm. This simply means this is a function that describes the amount of memory space taken by the algorithm. 1.5 Influence of object oriented programming concepts on data structures According to Matt A.Weisfeld,(2004) Object oriented programming has been around in software development from 1960s. The fact that Object oriented programming helps encapsulate the data and the operations that manipulate them in the object is considered as an advantage that arises from object oriented programming. Tim Patrick et al has explained that when it comes to object oriented programming, there are four main concepts we need to be aware of, as follows. Abstraction Encapsulation Inheritance Polymorphism . Abstraction:- This is a view of an entity that includes only those aspects that are relevant to a situation. Encapsulation:- This is the process of converting abstraction into a usable software component. A simple explanation is restricting access to the attributes and methods of an object directly. Encapsulation helps encapsulate a process of a data structure. Example can be an array because of the encapsulation an output of an array would be the elements within the array it wont show how it was processed. Inheritance:- This makes it possible for OOP code to build classes that extend or restrict features in other existing classes. Without the need to fully re write the code. Simply speaking, inheritance can receive attributes and methods from super classes. When you take data structures there are special kinds of data structures identified as abstract data types. The inheritance concept can create new abstract data types from old. An example can be a stack. Use of inheritance allows a user to create a new stack from an old one. Polymorphism:- A simple explanation of polymorphism is that a recognised action can be performed differently in different situations by an object. The influence of polymorphism concept in data structures is that it creates operations that can be applicable for data structures which store more than one type of data. An example for this can be linked lists. A linked list can be implemented with operations of stacks and queues using polymorphism concept. These four concepts are included among the other principles of object oriented programming. The last three concepts from the four alone give an idea, how oriented programming object can influence data structures. Task 2 K 2.2 A stack and its procedure for various operations. According to V.rajaraman et al (0000) a stack is a memory location where the data are stored and retrieved in a location called top of the stack. When the data is entered the firstly entered data are pushed there for the first data to be entered will be retrieved last. Unlike a RAM where each of the data can be addressed separately in a stack the only data that can be addressed is the top of the stack. There are two main Operations associated with a stack, PUSH and POP.

The Devastating Suicide in Bone Essays -- Bone Essays
The Devastating Suicide in Boneà à à à In Bone, by Fae Myenne Ng, the character Ona Leong grows up in a Chinese-American family in San Francisco. Ona shared her home with two sisters that are extreme opposites, a mother who works in sweatshops and a father who works out at sea for long periods. Ona grew up loving every member of her family and each one of them believed that she was on the road to success. But on a day like any other, Ona commits suicide by jumping off of the thirteenth floor of the Nam building. Without any warning of her unhappiness, the family finds themselves only being able to guess as to why she would do such a thing. How did Ona express her unhappiness? And how does Ona's choice of suicide affect loved ones? à Suicide often follows depression, proving false the stereotype of depression being only general sadness. Depression can be anything from temporary to extreme, and from insignificant to greatly significant. What significant might be characterized as could be the outcome of a loss of ones life. In a case where a woman's husband committed suicide, the woman later said, "'He was like anybody else with depression. But it was much more extreme than he ever let us know'" (Robinson, R. 33). However, Ona Leong appeared no different up to the day that she jumped; never even appearing depressed. Throughout the novel, the impact of suicide is seen from within the home, leading back to early childhood. à When thinking back, every detail of a person's life can be thought of as being a clue to the mystery of suicide. After Ona's death, both mother and sister alike, ask themselves, "What could have saved Ona?... If I'd been living [at home with Ona] on the Alley, could I have had that talk with... ...the case of leaving a suicide note, can sometimes only explain so much, but actions do in fact speak louder. Taking your own life, in the case of Ona wanting to make a point, could quite possibly be the loudest action there is, an action impossible to ignore. à Works Cited: Robinson, Rita.
