Abstract: Adaptive systems are characterized by the ability to monitor changes in their volatile world and react to monitored changes when needed. The ultimate goal of adaptation is that users’ requirements are always met correctly and efficiently. Adaptation is traditionally driven by the changing state of the system internal and its surrounding environment. Such state should be monitored and analyzed to decide upon a suitable alternative behaviour to adopt. In this paper, we introduce another driver for adaptation which is the users’ collective judgement on the alternative behaviors of a system. This judgmenet should be infered from the individual users’ feedback given iteratviely during the lifetime of a system. Users’ feedback reflects their main interest which is the validity and the quality of a system behaviour as a means to meet their requirements. We propose social adaptation which is a specific kind of adaptation that treats users’ feedback, obtained during the software lifetime, as a primary driver in planning and guiding adaptation. We propose a novel requirements engineering modelling and analysis approach meant for systems adopting social adaptation. We evaluate our approach by applying it in practice and report on the results.
1 INTRODUCTION
Self-adaptive systems are designed to autonomously monitor and respond to changes in the operational environment and the system’s own state (Laddaga,
1997). Each change can trigger a different response to satisfy or maintain the…...

Cultural Adaptation

...ESSAY To what extent are you convinced by Tange’s (2005) position regarding cultural adaptation? In the new global economy, the model of cultural acculturation proposed by Hanne Tange has become a central issue that concerns international business about sojourner adaptation into foreign society. Author points out that by recalling sojourners to their own country without completing the process of acculturation into the host culture will lead to the loss of obtained intercultural experience that is significant resource for profit of international business. The process of cultural integration is divided into three stages: the arrival in a new country, the two-year crisis and the intercultural phase. The purpose of this essay is to review recent research into multicultural business communication that has been presented by Hanne Tange in 2005, assistant professor in School of business. The author’s aim is to argue Lysgaards U-curve model that has been conducted in 1995 in relevant field among Norwegian Fulbright students in the United States of America, that has been most cited in cultural adjustment researches. The research examines the process of cultural integration of sojourners into the host country, particularly among seven Scottish immigrants in Copenhagen. The approach taken by Tange provides the opportunity to examine the immigrants’ experience in the host culture in a qualitative research framework. The methodology has a number of attractive and controversial features...

Sensory Adaptation

...Introduction For this paper I will provide definitions for adaptation. It will show how adaptation is evident in the experiments. It will show some of the senses that are present in the human body. Sensory Adaptation “Adaptation is the continued presentation of the same stimulus that causes the receptors to become less sensitive to that particular stimulus; therefore a stronger stimulus is required to activate the receptors”(Davis & Palladino, 2010). With adaptation individuals become acustom to the environment around them. So sensory adaptataion is the decrease appearance of sensitivity to stimulation that results from repeated appearance of the stimulation. The human has five senses: sight, sound, smell, taste, and touch. There will be examples and results from experiments. Examples is the best way to provide information about these senses. The first is the most common adjustment to temperture. You have seen these people that jump in to ice cold water in the winter. These people are members of the polar bear club. When they first jump into the water it is very cold, but after they have been in it for some time their body adjust to the temperture of the water and it is not as cold to them. Another is the sense of smell. You prepare the vegetables and meat for a stew and place them in a slow cooker. During the time you are at work all of these ingredients have been cooking. When you arrive home from work you are greeted by the aroma of the stew. ......

Sensory Adaptation

...Sensory Adaptation American Intercontinental University Sensory Adaptation The three experiments I chose to conduct were Experiment 1, Experiment 2, and Experiment 4. All of the experiments were interesting in their own way. Each experiment had a different outcome but all support adaptation within the experiment. Beginning experiment 1 I purchased a small piece of very coarse sandpaper at the local hardware store. I began by rubbing my index fingers across the sandpaper a few times. The first time I rated the coarseness high on the scale as an 8 and as the experiment progressed I began to rate the coarseness lower and lower on the one to ten scale. Adaptation is evident in this experiment with every rub of my fingers across the sandpaper it felt less abrasive than the first time. My sense of touch adapted to the rough surface with every swipe of my finger. The results of this experiment surprised me my hypothesis prior to conducting the experiments was that my estimate of the level of coarseness would hover around the same number. To set up for experiment 2 I prepared one cup of sugar and water mixed together and another cup of fresh water. I took a sip of the sugar water and swished it around my mouth for awhile then spit it out. Afterwards I took a sip of the fresh water and surprisingly enough it tasted sweet still. I was very surprised that the fresh water tasted sweet after I had spit the sugar water out. I was defiantly surprised with...

Concept of Adaptation

...Megan Dotter Concept of Adaptation Aspects of Psychology SSCI206-1204B-04 Biological Influences IP Week 2 Abstract Teaching a class about the concept of adaptation to a psychology class, experiments could be conducted to help them learn what adaptation is all about. Firsthand knowledge is the best way to teach a large group of people about a concept they may otherwise not fully understand. In this paper you will see and read about some of the findings experienced during this time. Concept of Adaptation This is a new experience for me to teach a class anything so I will begin by giving the information the students should know about adaptation and the examples needed to ensure they understand. After completing that part of the presentation I think it may be beneficial for the students to learn by firsthand experience. There are a few experiments that could be very interesting for them to do on themselves and others. The concept of adaptation is defined as “Diminished sensitivity as a consequence of constant stimulation ("Psych m.d. –," )” or “The tendency of a sensory system to adjust as a result of repeated exposure to a specific type of stimulus such as low levels of light ("Psych m.d. –," ).” An easier way to understand the concept may be to call it sensory adaptation. This explains in the name alone that it will be dealing with the 5 senses we have. Included in these five senses are taste, touch, smell, sight and hearing. I will be touching base on each......

Brazilian Adaptation

...Brazilian Adaptation When dealing with business matters in another country or with professionals from another country, it is important to recognize any cultural differences that could cause potential problems if not handled properly. Communication styles can vary drastically between the cultural divides of our great planet. Verbal, as well as nonverbal, messages must be adapted to meet the needs of whichever country is being courted. Brazil is no different. While there are many similarities between the U.S. and Brazil, one major difference, on the business front, is the communication style. While most U.S. business offices are very formal in terms of ideas and debate, utilizing mostly written protocol, Brazilian business professionals tend to communicate matters more orally. According to “Brazilian Communication Styles” (2010) website, the manner in which meetings are discussed can be extremely emotional and often theatrical when compared to the traditional U.S. model. Exaggerated body language and intense eye contact can illuminate any board meeting. If one were to not understand this cultural contrast, certain negative implications could arise. The top echelon of the American business world is dominated by males, this is a known fact. Therefore, most companies are not used to catering to female leaders. However, Brazil is leading the way for a new breed of CEO, the educated and motivated woman. Hewlett (2011), “In Brazil, 14% of the CEOs of large......

Sensory Adaptation

...| Sensory Adaptation | Psychology Unit 2 IP | | Pamela Bradford 21571629 | 8/4/2013 | This paper will provide experiments to explain Sensory Adaption of the human body. | Sensory adaptation is the process by which senses become less responsive to particular stimuli. Consider the enjoyment of flowers in a garden at dusk. When the surroundings are brightly lit, the red of a rose or geranium will appear bright against the greens and blues of their leaves. As darkness falls, however, the greens and blues appear brighter, and the red of the flower becomes harder to see. Some people take advantage of this phenomenon by planting “moon gardens,” which are gardens filled with whites, greens, and blues. All of these elements reflect the capability of the visual system.(Editorial Board.2011) Experiment 1: I placed 3 bowls of water on the counter. The first one is filled with hot, not painfully hot, tap water. The second is lukewarm water (a mixture of hot and cold water). The third is filled with cold tap water. To begin I will place my left hand in the hot and the right hand in the cold for a few seconds, then emerge both hands into the lukewarm water. When I put my hand in the hot water, I sensed a tingling sensation. The hand in the cold water started to get a cool numbing sensation. When I placed them in the lukewarm water, it was like my hands felt “normal” again. The skin also has receptors that respond to tactile pressure. People can feel fine points more......

Concept of Adaptation

...Concept of Adaptation Concept of Adaptation Kimberly Johnson Intro to Psychology When we are given the word adaptation we look at the root word which is adapt. It means to make suitable to or to fit. So the word adaptation means the act or process of adapting. I will be conducting 3 experiments in which I will test weather my response is me adapting to the change or if I will not. The three experiments that I will be conducting are first I will test the temperatures of water and see how my sense of touch adapts to the change in temperature. Next I will test my since of taste. I will be tasting sugar water and I will see how my tongue adapts to it verses plain water. Last but not least I will again test my sense of touch with sand paper. After doing each of these three experiments I will be able to clearly define weather or not my senses adapt to change or not. The first experiment is as I stated before me testing my sense of touch. I have the three bowls in front of me the left one with the hot water and the right one with the cold water. The middle bowl has the Luke warm water in it. As I submerged my hands in the right and left bowl, my mind already knows what to expect and even thought my mind knows what is coming, when my hands hit the water it still is a shock with both the hot and cold water. Chills run up both arms and I even shiver a little bit. My hands have to stay here for at least 3 minutes. During this time my left hand is adapting to the hot water but......

Science- Adaptation

...Adaptations. The animals: In the desert. There are numerous animals that live within the Sahara desert; all of these are adapted to cope with the conditions of the habitat. They all have certain features that make them different to animals that may live in a different habitat, like a polar bear. When we look at animals it’s not always obvious that they have all these essential adaptations that make them stay alive. For example, Fennec fox has large 6” ears, thick fur, sand coloured fur, fur on their feet and kidneys that restrict water loss. This is all important; in fact without all this the fennec fox may be unable to live! The large ears help get rid of heat quickly in hot dessert days because they have a large surface area, the thick fur insulates in the cold, open nights in the Sahara, the golden brown fur is camouflage against any predators that might also live in the habitat and not only is the fur a camouflage and insulator it also helps them walk on the loose sand- it does a lot! The kidneys are vital to the sand fox as well; they are specially formed to restrict water loss which is very important as there is a struggle for water in the desert. Another animal that is widely adapted to the desert habitat is the camel; the most obvious of all is that it has a hump to store water, or is it? Surprisingly, a camel doesn’t store water in its hump it in fact store fat so it can be released slowly as energy when needed. A camel can go a week without water and several......

Adaptation and Hamlet

...Adaptation or Appropriation Shakespeare’s play, Hamlet can be noted to be one of his most historic play writes of significance. The adaptation of the play into a movie directed by Franco Zefferelli was directly due to the importance of the story. The movie compared to the play write has many similarities and many differences. These differences were not intended to change the plot or the perspective, it was intended to merely intensify what’s going on, shorten the plot and give the viewer an easier understanding of what’s going on. In the beginning of Shakespeare’s play, the ghost of the king had been seen by Horatio and the guards and they intended to let Hamlet speak to whom ever it was because they didn’t know if it was a trick or what it was.. In the movie they are at the king’s funeral and Gertrude and Hamlet are next to the coffin, Hamlet sprinkles some dust on the coffin and Claudius touches his sword against it. The reason for this opening scene to be changed would be due to the fact that in the play it says that Hamlet came after his father’s funeral. Within the context of the movie it is easier to figure out that Hamlet doesn’t just want revenge but he wants justice. Although Hamlet never states that Claudius’ actions must follow with his death, which is actually what happens. In both the play and the film Hamlet waits to try and kill Claudius. However in the film he doesn’t seem to be upset over what he has to do and he doesn’t seem like an assassin. This......

An Analysis of Eric Klinenberg "Adaptation"

... Adaptation Name Institution Adaptation Global warming and climate change exist, and the two have called for a world attention to reducing their impacts. The Great Eight nations, including U.S., have convened various global summits where heads of states come to debate how to counter the increased climate change. Various recommendations have been proposed to counter the effects of climate change and devise ways in which the change are accommodated. This paper will discuss the rhetorical questions asked by the author of the journal article. ‘Adaptation’ is authored by Eric Klinenberg and is published in a journal called The New Yorker. The targeted audience is the people of New York, who have suffered the effects of climate change in the city. The article is written by the department of urban planning. This gives the author authority to address his audience since the department is concerned with enlightening the urban population about things that affect their everyday life. The date of publication is January 2013 making it relevant even to date. The city of New York is still subject to heat waves, hurricanes, and floods. The journal article is titled Adaptation: How can cities be “climate proofed”. The title articulates the content since it is taking about adapting to climate change in New York and other cities. This is after Hurricane Sandy that occurred in New York. The author focuses on how cities can take measures to adapt to weather changes. By climate proofing, the......

Social Learning and Adaptation

...because they circumvent the psychological, environmental, and social nexus of which drug use is a part. One branch of conditioning theory, social-learning theory (Bandura 1977), has opened itself to the subjective elements of reinforcement. For example, Bandura described how a psychotic who continued his delusional behavior in order to ward off invisible terrors was acting in line with a reinforcement schedule that was efficacious despite its existing solely in the individual's mind. The essential insight that reinforcers gain meaning only from a given human context enables us to understand (1) why different people react differently to the same drugs, (2) how people can modify these reactions through their own efforts, and (3) how people's relationships with their environments determine drug reactions rather than vice versa. Social-learning theorists have been especially active in alcoholism, where they have analyzed how alcoholics' expectations and beliefs about what alcohol will do for them influence the rewards and behaviors associated with drinking (Marlatt 1978; Wilson 1981). Yet it has also been social-learning theorists who have launched the alcohol-dependence syndrome and who seem to feel subjective interpretation is far less important than the pharmacological effects of alcohol in causing drinking problems (Hodgson et al. 1978, 1979). This lacuna in their theorizing is most noticeable in the inability of modem social-learning theorists to make sense out of cultural......

Roy Adaptation Theory

...Running head: ROY’S ADAPTATION MODEL Nursing theory is an organized framework of concepts that are designed to guide nursing practice and provide a foundation for clinical decision-making. There are many different types of nursing theories. This present paper will focus on one of the Grand theories, the Roy Adaptation model (RAM). The paper is divided into four main sections focusing on the importance of the RAM; summary of key concepts; view of RAM on specialization; and conclusion. There has been an evolution of nursing practice from when Florence Nightingale started. Nurses used to take direct medical direction to an evolution of independence. Today, advanced practice nurses are PHD, DNP, researchers, nurse practitioners, leadership positions in health care organizations, and education . The independence of the nursing profession has occurred in part due to an evolution of nursing theories. The importance of the nursing theories is that they provide framework for nursing practice. There are more than thirty different theorists who have helped contribute to the process. Broadly, these thirty theories can be divided into three major categories Grand theory, Middle theory, and practice. The present paper focuses on the Roy Adaptation Model (RAM) of the Grand Theory. This was chosen as it approaches the care of the patient using a scientific and holistic approach, which aligns with my personal practice as a nurse and belief system. Initially, this model was......

Sensory Adaptation

...Introduction: Adaptation in sensory evaluation of food refers to the slow drop of sensation (in constant magnitude) after the stimulus has been fully switched on (Lawless & Heyman, 1993). They also added that after a certain time this sensation can completely disappear or in some instances the taste persists that shows a degree of taste adaptation. This idea usually occurs when the perceived taste intensity of one product reduces the other different product. For example, water can taste sour or bitter after a salt adaptation. On the other hand, taste interaction masks the interaction between mixtures of different tastes (Lawless & Heyman, 1993). A solution of sucrose (sweet) and quinine (bitter) will taste less sweet than a pure sucrose solution of the same strength. According to Lawless and Heyman (1993), these sensations are distinguished by taste buds present on the tongue namely fungiform, circumvallate and foliate. They contain 30 to 50 taste receptor cells (TRCs). TRCs protrude hair-like cilia called microvillae to the surface of the taste buds that form the taste pore. This then comes into contact with the saliva. It is believed that flavoursome molecules from food bind to microvillae at the top of the taste cells. After binding, the taste-producing compounds (tastants) transfer sensations to the tongue and beyond by different pathways. For chemicals that produce sweet, umami and bitter tastes they use similar receptors called G- protein coupled receptors......

Sensory Adaptation

...Sensory Adaptation Jessica Munden American Intercontinental University Abstract This paper will define and explain the concept of sensory adaptation. Three experiments were conducted to show sensory adaptation. This paper will report the experiments findings by illustrating what was experienced during the experiment. This paper will also discuss how adaptation is important from an evolutionary perspective. Sensory Adaptation Chemical senses, such as taste and smell, and the skin can be affected by sensory adaptation. It is important to understand the systems related to the chemical senses and the skin in order to understand how they can be affected by sensory adaptation. Three experiments were conducted to help explain sensory adaptation, which will appear later. Sensory Adaptation is defined in Words of Wisdom (2011) as “the process by which senses become less responsive to particular stimuli." In other words, when certain stimulus is continued the brain's sensory responses become less responsive. Adaptation affects the sensory systems, which include the five senses vision, taste, smell, hearing, and touch. When a non-smoker walks into a home, in which a person smokes inside, the smell of nicotine will be overwhelming. After spending some time in the home the smell of nicotine will seem to dissipate because one's system will adapt to the smell (Words of Wisdom, 2011). An experiment was conducted to show sensory adaptation to touch. During this experiment, one......
