Herpes HERPES-SIMPLEX - TYPE 2 Herpes is a name that is used to describe several types of skin eruptions that are characterized by formation of blisters. The term embraces primarily two distinct disorders, herpes simplex and herpes zoster, both caused by viruses. Together, these herpes viruses are estimated to cause more human illnesses than any other group of viruses. Two types of herpes simplex are known. The first causes cold sores or fever blisters, which is an eruption of blisters that often occurs during the course of or after one of a variety of diseases that eventually cause fever (most commonly average colds, the flu, and pneumonia). The blisters usually appear around the mouth and on the lips (herpes labialis), about the nose, face, and ears, and in the mouth and pharynx. The causative virus has been shown to be present in the cell bodies of the facial nerve in persons who do not have blisters. It is this reservoir of latent virus that is the source of repeated attacks. Except for lotions to relieve pain, itching, or inflammation, no established treatmemt has actually been developed. The second type of the herpes simplex virus, however, is the usual cause of genital herpes. Herpes infections of the genital area have become increasingly Herpes,page 2 common, going along with a rise in general of many sexually transmitted diseases. Sometimes accompanied by headache and fever, the condition usually begins with a mild itching, followed by the development of clusters of blisters that break and crust to form scabs that eventually dry up. The process may last one to three weeks. In many cases new clusters of blisters appear as others heal. When a baby is born to a woman who has active genital herpes lesions, the infant is at high risk of contracting an infection that is often fatal, so these women usually have their babies delivered by a cesarian section. Primary cases of genital herpes can be treated by a drug called acyclovir, which was approved in 1982 and in another form, that is to be taken orally rather than used in an ointment form, in 1984. It also has been proving useful against recurrent attacks. The virus can also invade the central nervous system, or CNS, especially in people who are weakened by other diseases, such as cancer, causing a severe case of encephalitis. Early treatment of herpetic encephalitis with the drug acyclovir can prevent death and brain damage in many cases. How can herpes be prevented? Because the disease is transmitted most often through bodily fluids, the simpliest protection is to simply protect yourself. During Herpes, page 3 sex, one of the partners should definitely be wearing a condom, and that alone will greatly cut down an individual's chances of acquiring the virus of herpes-simplex type-2.

Kellys cognitive theory

Kellys cognitive theory Human personality has been a complex issue for long and has inspired theorists to create ideas to enhance the understanding of the subject. The theorists have made several attempts to understand and explain how the personalities are developed, their variations, how they affect human interactions with the world and their relationships with different psychologically-related disorders.Advertising We will write a custom essay sample on Kelly’s cognitive theory specifically for you for only $16.05 $11/page Learn More George Kelly is one of the proponents of the cognitive theory which is the focus of this study. The center of Kelly’s cognitive theory is the manner in which individuals think because their thoughts affect their feelings and actions.The thoughts and feelings of individuals determine their personalities. Kelly identifies the major role in which the human cognition element plays in determining personality. This aspect forms the foundation of the terminology of personal constructs which refers to the different ways in which individuals collect information and with the support of their understanding, use it to predict events (Kelly, 2006). The individual interacts with the world based on the outcome of his prediction and this interaction becomes his personality. Kelly’s incisive evaluation on individuality is informed by the need to equate individuals to scientists. He postulates that the objectives of scientists can be linked to those of other beings. He suggests that in the same way that scientists build hypotheses and conduct experiments to establish their validity, people also develop theories based on their personal constructs and consequently employ various theories to predict events. However, the constructs may at times be influenced by the individuals’ past experiences that may not be relevant to their present societal circumstances hence rendering the constructs invalid. The distorted constructs cannot be used to predict events because they cannot hold new data entry due to their unchangeable nature. Given that constructs are limited in nature and cannot therefore be employed in all situations, individuals may at times be required to revise their constructs to accommodate data that is created by new experiences. The choice that an individual makes in order to change his construct is what Kelly calls â€Å"constructive alternativism†. The premise of his theory is based on the fact that â€Å"a person’s processes are psychologically determined by the ways in which he anticipates events† (Van der Kolk, Fisler, 2005). This proposition is known as the fundamental postulate, meaning that individuals’ actions determine their worldly expectations especially those which are founded on past experiences.Advertising Looking for essay on psychology?

Kelly also categorizes 11 corollaries under the postulate to expound the process of information interpretation which include expectation, experience and action. The construction corollary The individuals’ construction of anticipation is founded on their interpretation of replication meaning that their expectations are based on past happenings. The experience corollary Here, the construction system of an individual differs with his understanding of replication meaning that when events are not as anticipated, their constructs are altered or reconstructed. The dichotomy corollary The constructs are stored experiences which the individuals use to perceive the world and â€Å"guide† their actions. These constructs are usually unique to every individual hence the term, â€Å"personal constructs†. The organization corollary An interrelation exists between the constructs in regard to associational networks and chains of command in that the associations may be strong or weak. The range corollary The effectiveness of constructs is limited to several situations meaning that certain constructs can be extensive, whereas others can be narrow. The modulation corollary The range of certain constructs can be adjusted so as to hold new information but others cannot, meaning that certain ranges can be expanded and others cannot. The expansion of the range is known as dilation and the narrowing of the range is called constriction.Advertising We will write a custom essay sample on Kelly’s cognitive theory specifically for you for only $16.05 $11/page Learn More The choice corollary The individual has the choice of acquiring new experiences in order to broaden his constructs or reject them and keep them as â€Å"safe† but minimized constructs. The individuality corollary Due to the fact that in dividuals’ experiences vary, their constructs also tend to be different. The commonality corollary Even though individuals are different, to some extent certain of their experiences are alike leading to similar constructs. This fact is necessitated by the concept that shows that their perception of the world may be similar. The fragmentation corollary The variation in situations and positions in which an individual can be destined to be in can bring out divergence in the constructs. The sociality corollary This cognitive scope determines how an individual interacts with another depending on their comprehension of their constructs. Kelly’s theory suggests that individuals do not need motivation since they are not inactive nor are they recipients. This fact is enhanced by the idea that individuals may be living and hence destined to move. The only time individuals stop moving is when they die (Target Fonagy, 2001). Construction transitions Kelly’s constructs of t ransition refer to emotions and occur when an individual alters his construction systems after an experience which can in turn create anxiety, hostility and in certain cases, guilt. However, the construction systems also offer opportunities for reconstruction. When individuals find themselves in circumstances that their constructs have not earlier foreseen or encountered, they experience anxiety because they realize that their constructs are ineffective. Guilt manifests itself when one does not keep to the constructs that he identifies with. In the event that one’s constructs are not in line with the world, one can attempt to modulate the reality to fit into one’s constructs.Advertising Looking for essay on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More This aspect is known as aggression which can turn into hostility when the individual is persistent in trying to change reality so that it can conform to their constructs instead of their altering the constructs. An individual is said to have a psychological disorder when he refuses to reconstruct. Subsequently, he may not able to anticipate and accommodate new information. Kelly’s theory has had massive influence on later psychology and movement as it has been applied in disorders like schizophrenia, depression and addiction. The Kellian therapy functions by making individuals to either â€Å"relax† their constructs. The constructs are tested to determine their functionality and are used to verify their applicability and movement. The mentioned steps can be accomplished by employing â€Å"role-play†. The psychotherapy is based on reconstruction, which is founded on encouraging the individuals to change their constructs. This aspect is what is referred to as move ment. Kelly states that a theory has to be useful to be declared valid. The fact that his theory has been applicable in psychotherapy and psychology worldwide leads one to determine that his theory is indeed valid. Kelly’s theory is supported by several peer reviewed articles. One of the articles is titled, Self-discrepancy: A theory relating self and affect written by Troy Higgins. It states that the vulnerabilities of emotions are interrelated with different inconsistencies involving â€Å"self-state† representations. It suggests that these inconsistencies are symbolic of the various harmful psychological circumstances related to various anxieties. The variations connecting the real self-concept and the model self-concept indicate that positive results may be inexistent. These inconsistencies and negative results can be related to emotions like hostility, threats and anxiety. The peer reviewed article thus supports Kelly’s constructs of transition. In another article titled, Personal construct psychology and the cognitive revolution, the writers Brien Graines and Mildred Shaw relate learning and motivation to the psychology of personal constructs. They state that the process of learning conforms to the postulate formulated by Kelly in the sense that an individual needs to alter his constructs to accommodate new information. In regard to motivation, Kelly includes this aspect within the choice corollary whereby the individual can choose to acquire new information in order to expand his construct (Schultz Schultz, 2009). The article by Dr. Christopher L. Heffra titled, Personality perspective on the other hand also validates Kelly’s theory by highlighting its usefulness. It does this by stating the relevance of the cognitive theory in treating psychological disorders like depression and other disorders associated with anxiety. The two â€Å"cognitivists† who stand out most in the theories’ application include Aaron Be ck and Albert Ellis. Their application is successful because they concur that by changing the way in which one thinks; actions and feelings can also be changed since the latter aspects are determined by thoughts or constructs and as a result, various negative personality features can be eliminated. The application of the theory in treatment can be evidenced by Becks evaluation systems; Beck Depression and Anxiety Inventory (BDI and BAI) and Ellis’ ABC technique. Heffra cites the important role that studies have played in bringing out the importance of employing cognitive treatment over medication in dealing with depression as its effects last longer. Although the theory received a great deal of support through the insights into individuals’ thought processes and perceptions as provided by studies, it did record some faults. Critics term the theory as â€Å"weak† because of the theoretical nature of constructs and the lack of consensus in the way the theory is de scribed or applied. References Kelly, G. A. (2006).

Analytical report Term Paper Example | Topics and Well Written Essays - 500 words

Analytical report - Term Paper Example Numerous countries in the world do not use the floating exchange rate system due to its fluctuating nature. However, in this situation, it would be best for the small country to use this system since it has more positives than negatives when it comes to growth. The recommendations in favor of this system and some of its disadvantages are discussed below. One of the main advantages of this type of system is the fact that there is an automatic balance of payment adjustments. This means that if there is disequilibrium in the balance of payments, it is normally be corrected by changes in the exchange rate system. This means that if a country has disequilibrium in the balance of payment, then it means that the currency would have to decrease in value. First of all the disequilibrium is brought forth by the fact that the exports outweigh the imports in terms of supply. Therefore, the local currency would be greatly supplied in the foreign market (Bized, 2011, para. 4). This would drive the value of the local currency down and would mean that the imports would be made more expensive and the exports cheaper. This would lead to an automatic increase in demand for the exports which would ultimately result to a balance of payment adjustment. The other main advantage of this type of system is that it frees the internal policy. This means that t he balance of payment is usually rectified when there is disequilibrium by a change in the external price of the local currency. This is as opposed to a fixed exchange rate system in which if there is disequilibrium it means that there is the need to cause a general deflationary. This deflationary could result to the general unemployment of the citizenry. The other main advantage of this type of system is that the country would be free from economic crisis but not completely as money is usually

Analysis of The Secret Essay Example | Topics and Well Written Essays - 750 words

Analysis of The Secret - Essay Example The film explicit that human mind is full of negative and positive thoughts. However, in the overall thinking process either positivity or negativity gets complete hold of the mind. If the mind is under the control of positive attraction then things that people plan to achieve are acquired easily (â€Å"The Secret†, n. p.). This concept of positive attraction has actually played a significant role in my coming to the college such that all through my childhood and early teenage I heard and saw people enjoying their college life and building successful careers. Since then onwards I developed an entirely positive thinking about getting into the college. As it is explained in the film that internal positivity attracts external positivity (â€Å"The Secret†, n. p.), the same thing happened with me. I began to make friends who were also fond of getting into college with the similar positive thoughts and intensity. Since through the initial point I had concentrated on the posi tive attributes of college therefore ultimately I ended up in gaining positive outcomes. Visualization, affirmation and law of attraction can be explained as the core principles leading towards a successful and contented life (â€Å"The Secret†, n. p.). Let’s consider visualization, whatever I will be thinking about in my college life that I will visualize in my mind throughout that period. For instance, I can use this principle to be a competent student in my college through visualizing its positive and long lasting outcomes. Moreover, I can visualize myself as the best student of the year so as to remain motivated, to strive more and learn more. The second principle talks about affirmation which is actually correlated with the principle of visualization. For instance, in order to be a successful student and later a successful professional I will have to be affirmative upon my visualization such that whatever my mind is thinking about is all attainable and achievable. Building affirmation is slightly more difficult than visualizing what you want and therefore it must be supported by positive and highly acknowledgeable individuals who have already attained what I am striving for (â€Å"The Secret†, n. p.). This will significantly help me in affirming my visual thinking while simultaneously aligning all the academic goals and objectives of my life with my thoughts. Last is the law of attraction, as discussed in the film visualization and law of attraction play an equivalent role in a person’s life since I will visualize things towards which I am actually attracted (â€Å"The Secret†, n. p.). For instance, I like seeing people getting high grades and having good academic records; therefore, I am always attracted to higher grades and visualize the same for myself. Since our attractions are also attracted towards ourselves due to positive emissions therefore I will be careful in building attractions towards different things in my college life so as to eliminate all those elements of the college environment which are not consistent with my academic goals. For further explanation following are the examples of how I will use all three principles in order to achieve success in my college life. Visualization: I can use this principle through imagining that I have got the best college teachers. In addition to this I can imagine having highest grades in college while maintaining good record of extracurricular activities. Affirmation: Affirmation of what I am visualizing is the most important part of the overall process which

Adaptive leader Essay Example | Topics and Well Written Essays - 250 words

Adaptive leader - Essay Example They are able to be flexible and open to the possibilities that the environment gives at any given moment. The war in Iraq has called for all leadership to be adaptive because there was no manual to describe what they needed to do in situations like Iraq. As an example, the Army had no information about a "counterinsurgency campaign" and there was nothing by which to measure it. This meant that the leadership had to adapt quickly into creating something that would be done and how it would be measured. In order to be adaptive a leader must also be able to challenge assumptions and perceptions. They must look past the obvious to see the greater picture within their environment, especially when they are in combat. They must be able to perceive what is going on and then be able to see which elements are critical to the change; this is not always easy for a military officer to do (Whiffen 3). The officer must also be able to balance "force and restraint" (Wiffen 5) as he or she goes about the operations. This aspect calls on the officer to know his strengths and weaknesses and then the strengths and weaknesses of his company. In order to learn how to adapt officers must put themselves in situations that are uncomfortable and unfamiliar so they can "adapt by adapting". (Whiffen

History and Current applications of Behaviorist Theory

History and Current applications of Behaviorist Theory Behaviorism is a theory of learning. Behaviorism proposes that learning is based on the thought that all behaviors are gained when they are conditioned. The theory of behaviorism supposes that behavior can be studied in a controlled manner and according to John B. Watson we can observe it and it should have nothing to do with introspection because introspection is too subjective (Goodwin, 2008). Besides John B. Watson there were others also interested in the study of behavior, specifically, Ivan Pavlov and Burrhus F Skinner. Behaviorism was a major change from earlier views because it discarded the importance of the conscious and unconscious mind and instead it attempted to make psychology a more scientific field, by focusing just on the observable behavior. Behaviorism had its earliest start with the work of Ivan Pavlovs and his research on the digestive systems of dogs that led him to the discovery of classical conditioning process, which demonstrated that behaviors could be learne d through conditioned associations (Goodwin, 2008). This paper will discuss the work of Pavlov, Watson and Skinner and how they contributed to todays behaviorist theories like cognitive behavioral therapy. It will also discuss how these early behaviorists theories are the same as todays behaviorist theories and how they are different. The History and Current applications of Behaviorist Theory Behavioral psychology otherwise known as behaviorism is a theory of learning based upon the idea that all our behaviors are gained via conditioning. Conditioning occurs through our interactions with our surroundings. Behaviorism proposes that behavior can be studied in an organized and observable way without consideration or thought of inner psychological conditions (Goodwin, 2008). There are two major types of conditioning in behaviorism, classical conditioning and operant conditioning. When you take a natural occurring stimulus and then pair it with a response a behaviorist calls this classical conditioning and is a technique used in behavioral training. It involves taking a neutral stimulus (i.e. the ringing of a bell) and then pairing it with a naturally occurring stimulus (i.e. dogs salivate when presented with food). Continuing this pairing will inevitably cause the neutral stimulus, that was formerly introduced to create the response without the introduction of the naturally o ccurring stimulus (i.e. the dog will salivate with the ringing of the bell even when food is not immediately presented). The two components are then called the conditioned stimulus (the ring of the bell) and the conditioned response (the dog salivating) (Todes, 2002). Operant conditioning is the idea that learning occurs because rewards and/or punishments are consequences for behavior. With operant conditioning, a relationship is created linking a behavior and a consequence for that behavior (Skinner, 1954). Ivan Pavlov, John B. Watson and Burrhus F. Skinner all developed significant contributions to the advancement of behaviorism. While Pavlov, Watson and Skinner paved the way for behaviorist thinking, what is left of their findings? If we take a critical look at cognitive behavioral therapy we can see how the early behaviorists ideas are still alive today and how these ideas have changed with time. In the late 1800s, Pavlov was studying the gastric function of dogs. Pavlov inadvertently discovered that dogs would salivate prior to the food being presented to them, and decided that his discovery of dogs salivating prior to the actual food arriving was more interesting than gastric functions, and changed the focus of his research (Goodwin, 2008). Pavlov experimented using a tone for dogs alerting them that food was available. What Pavlov found was that his dogs began to salivate when the tone was introduced even when the food was not readily available (Schwartz Lacy, 1982). Pavlov realized that when his dogs salivated at the sound of the tone, this response is not a natural response but instead it was a learned response, and he consequently called this response a conditioned response and the neutral stimulus (presentation of the food) became a conditioned stimulus (Beecroft, 1966). Pavlovs work became known in the West, mainly due to the writings of John B. Watson. Pavlov thus c oined what we now know today as classical conditioning. Pavlovs research also had a direct affect on bringing behaviorism to the attention of the American public in the 1930s. John B. Watson is known as the founder of behaviorism however  Watsons Behaviorism did not catch on immediately and in 1913 when he publicized his Behaviorist Manifesto,   he was initially met with a lot of criticism and doubt (Goodwin, 2008). It was not until the early 1930s when behaviorism began to catch the attention of America, in part due to Watsons continued push on the public to recognize it as a valid theory in psychology. Finally after several articles were published citing the use of behaviorism as a way to improve lives, the public began to recognize behaviorism as a positive, meaning it could help to raise children more efficiently, improve marriages, improve business and overall help people to lead more productive lives (Goodwin, 2008). With Watsons book, Psychology as the Behaviorist Views It, behaviorism for the first time was given well defined goals, methods and thought (Goodwin, 2008).   Watson made behaviorism a discipline that created a structure based heav ily on the principle that learning is the key to development and behavior (Rilling, 2000).   In 1927, Watson and his then assistant, Rayner conducted a study that produced an intense fear of rats in a 9 month old boy they called little Albert. When little Albert reached for a white rat, Watson would make a loud noise that scared little Albert. What occurred in little Albert is what is known as classical conditioning. When Little Albert heard the load noise at the same time as seeing the whit rat he made an association between the two. Little Albert then shifted his fear with the noise to a fear of rats. In addition to classical conditioning, second order conditioning occurred as Little Albert then associated rats, which have fur, to all things with fur (Goodwin, 2008). Because of this second order conditioning, little Albert then believed all things with fur would produce a scary noise and he became afraid of all things that had fur (Mischel, 1993). Although Watson was asked to le ave John Hopkins and essentially could no longer work in academia he continued to promote his belief in behaviorism until it finally caught the attention of the American public. The impact of behaviorism was huge, and was a school of thought that continued to dominate psychology for the next fifty years. Psychologist B.F Skinner advanced the behaviorist perspective with his theory of operant conditioning. Operant conditioning verified the effect of punishment and positive reinforcement on behavior. There are two factors in operant conditioning, the response and the consequence (Skinner, 1954). If the consequence is positively reinforcing, then there is the likelihood of getting a similar response. If the consequence is punishing the likelihood of repeating the response is not probable (Mischel, 1993). Skinner conducted an experiment known as the skinner- box (Goodwin, 2008). In Skinners experiment a rat would press a lever and the lever produced a piece of food which consequently taught the rat that if it pressed the lever it would get positively reinforced with a piece of food (Skinner, 1954). Skinner also produced separate results when he replaced the pushing of the lever with the consequence of a shock. When the rats pushed the lever and received a shock they almost immediately st opped pressing the lever (Skinner, 1954). Skinner also realized that if he stopped presenting food ( in a process called extinction) eventually the rat would stop pressing the lever as well but not as quickly as when a shock was received thus, proving that punishment was a greater deterrent to the behavior (Goodwin, 2008). When operant conditioning is used using the reward and punishment techniques as described in Skinners experiment, the same behaviors can be produced in a child (Schwartz, 1982). During 1950 to 1970 cognitive behavioral therapy (CBT) became widely utilized and was inspired by the behaviorist learning theories of Ivan Pavlov, John B. Watson and Clark L. Hull (Rachman, 1997). In the United States, psychologists were using B.F. Skinners behaviorism and applying it to clinical work and much of this work was focused towards severe, chronic psychiatric disorders such as psychotic behavior and autism (Rachman, 1997). The therapeutic approaches of Albert Ellis and Aaron T. Beck gained popularity among behavior therapists. These systems included behavioral elements and interventions that focused primarily on problems in the present. Elliss system began in the early 1950s and was called rational therapy and is one of the first forms of CBT. (Ellis, 1975). Aaron T. Beck developed cognitive therapy in 1960 after being inspired by Elliss work and Becks cognitive therapy became a favorite intervention technique to study in the psychotherapy research in academic settings. I nitial research focused on comparing this cognitive therapy with behavioral therapys to see which was more effective (Beck, 1975). During the 1980s and 1990s cognitive and behavioral therapys were officially merged into what we now know as cognitive behavioral therapy (CBT) (Rachman, 1997). Samuel Yochelson and Stanton Samenow introduced the idea that CBT approaches can be used successfully with the criminal population (Yochelson and Samenow, 1976). In conclusion, because behaviorism is based upon behaviors we can actually observe, it becomes much easier when performing research, to measure and collect data. Effective therapeutic techniques such as intensive behavioral intervention, rational therapy and CBT all get there beginnings from behaviorism. CBT, rational therapy and behavioral interventions are all useful approaches for changing harmful or maladaptive behaviors in children and adults. Some differences between todays CBT and behaviorism is that behaviorism is to basic of an approach to behavior and it does not take into account an individuals choice of free will or any internal stimulus such as a persons moods, thoughts, and feelings. Another criticism is that behaviorism does not take into consideration the fact that there are other forms of learning, such as the learning that can occur even when reinforcements or punishments are not introduced (Swartz and Lacey, 1982). Finally, behaviorism does not look at the fact tha t people are able to adapt behavior when new information is present, whether or not the initial behavior was established through reinforcement. Behaviorism without the addition of cognitive influences is not enough. When we can get an understanding of the thinking behind the behavior we have a better chance at changing it. In the words of Stan Samenow change the errors in thinking and we can change the behavior (Yochelson and Samenow, 1976).

Mobile Marketing Essay -- Technology, Mobile Applications

2.1 Handheld Mobile Devices and Mobile Applications 2.1.1 Defining Handheld Mobile Devices The medium for mobile applications is a mobile device. While the functions of mobile devices vary, the key criteria such a device must fulfil is portability. To that extent, mobile devices have been described as ‘interactive wireless media’ (Haghirian and Madlberger 2005, 2). Mobile devices offer a range of capabilities, but essentially they allow access to data and information with the opportunity of being used in a variety of environments (ISACA 2010, 2). The term ‘handheld mobile device’ indicates that the device is limited to something that can be ‘held in the hand(s)’. Even so, the term ‘handheld mobile device’ may represent a different meaning to different people and therefore can be anything from a PDA to a digital camera. For the purpose of this paper, the term handheld mobile device (henceforth abbreviated as mobile device) will be associated only with those mobile computing devices that have the capability of downloading third-party mobile applications (as defined in 2.1.3). Namely, these are smartphones, PDAs and tablet PCs. 2.1.1.1 Mobile phones There are many known terms for mobile phones including cell phone, basic phone, feature phone, traditional mobile phone, smartphone, and system phone. Nonetheless, it can be argued that mobile phones currently on the market are typically categorised as either ‘feature phones’ or a ‘smartphones’. The definitions of these two types are widely discussed and disputed by analysts, manufacturers, journalists, and end users. The lack of a standard definition can be attributed to the advancement of mobile phone technology. As the technology continues to evolve, definitions are subject to ch... ...s have existed since the development of mobile devices. â€Å"Downloadable† applications (such as DMO apps), however, have only spread and reached mainstream usage with the emergence of smartphones and PDAs (Holzer and Ondrus 2011, 22). Beyond the fundamental definition, there are a range of classifications that a mobile application may fall under. In their 2008 white paper on mobile applications, the Mobile Marketing Association (MMA) suggests that, from a technical viewpoint, mobile applications can be distinguished according to the runtime environment in which they function. The MMA lists three types of runtime environments, namely native platforms and operating systems, mobile web and browser runtimes, and other managed platforms and virtual machines. By and large, however, the industry makes a distinction between native applications and web-based applications.
