Dissociative Identity Disorder Essay Example for Free

Dissociative Identity Disorder Essay The syndrome commonly known as Multiple Personality Disorder but now called Dissociative Identity Disorder (American Psychiatric Association, 198) might be thought of as a recent phenomenon. The diagnostic literature shows the definition of multiple personality as evolving significantly over the editions of the Diagnostic and Statistical Manual of Mental Disorders. In the DSM-1, these behaviors were called dissociative reaction, (American Psychiatric Association, 1952), which came to be called hysterical neurosis, dissociative type in the DSM-II (American Psychiatric Association, 204). In each of these, multiple personality was not seen as a distinct disorder but was grouped with somnambulism, amnesia, and fugue states. Only in the DSM-III does Multiple Personality Disorder appear as a separate diagnostic category, with a definition of this behavior. This disorders defining features were argued to be the existence within the individual of two or more distinct personalities, each of which is dominant at a particular time (American Psychiatric Association, 257). The DSM-IIIR of 1987 gave nearly identical defining features as the existence within the individual of two or more distinct personalities or personality states (American Psychiatric Association, 269). The defining features evolved further in the DSM-IV where this behavior pattern came to be termed Dissociative Identity Disorder. Its features became the presence of two or more distinct identities or personality states that recurrently take control of behavior (American Psychiatric Association, 484). This subtle change is significant; distinct personalities were no longer seen as existing within the person or as a part of the person, but the behaviors displayed different states or identities. This definition is less organismic and more behavioral-environmental in theory than earlier versions. With the readers extrapolation, the personality is variable behavior or as topographical subdivisions of behavior, occasioned by discriminative stimuli and controlled by reinforcement contingencies. Here, the personality is showing more variability than that of the average or normal individual; the individual lacking one coherent personality displays a personal repertoire of behaviors which is very diverse, with large variability in the relationship between antecedents and responses. The antecedents, that is, people, places, events, and so forth, of the individual in question occasion more responses of an idiosyncratic nature which are maintained by reinforcement contingencies unique to that individual. Along t his approach, one writer took the new definition to mean that the individual displaying these behaviors could no longer be described as having more than one personality. Instead, the person should be viewed as having less than one whole, coherent personality (Sapulsky, 95). Similarly, Kohlenberg and Tsai (82) observed that these individuals may have not developed all the characteristics of a stable, single personality. History Multiple personality was first recognized and described by the French physician Pierre Janet the late 19th century. In the year 1982 psychiatrists were talking about â€Å"the multiple personality epidemic. Yet those were early days as multiple personal ¬ity became an official diagnosis of the American Psychiatric As ¬sociation only in 1980. Ten years earlier, in 1972, multiple personality had seemed to be a mere curiosity. â€Å"Less than a dozen cases have been reported in the last fifty years. † You could list every multiple personality recorded in the history of Western medicine, even if experts disagreed on how many of these cases were genuine as the word for the disorder was rare. Ten years later, in 1992, there were hundreds of multiples in treat ¬ment in every sizable town in North America. Even by 1986 it was thought that six thousand patients had been diagnosed. After that, one stopped counting and spoke about an exponential increase in the rate of diagnosis since 1980. Clinics, wards, units, and entire private hospitals dedicated to the illness were being established all over the continent. Maybe one person in twenty suffered from a dissociative disorder. Clinicians were still reporting occasional cases as they appeared in treatment. Soon the number of patients would be ¬come so overwhelming that only statistics could give an impression of the field (Modestin, 88-92). Public awareness of the disorder increased in contemporary times after a case was the subject of The Three Faces of Eve (1957). In the 1980s and early 90s, such factors as recognition of child abuse, public interest in memories recovered from childhood (whether of actual or imagined events), allegations of so-called satanic ritual abuse, and the willingness of many psychotherapists to assume a more directive role in their patients treatment, led to what came to be regarded as a rash of overdiagnoses of multiple personality. Causes The cause of multiple personality is not clearly understood, but the condition seems almost invariably to be associated with severe physical abuse and neglect in childhood. It is believed that amnesia the key to formation of the separate personalities occurs as a psychological barrier to seal off unbearably painful experiences from consciousness. The disorder often occurs in childhood but may not be recognized until much later. Social and psychological impairment ranges from mild to severe. The fairly-necessary-condition evolved together with the characterization of multiple personality disorder (MPD). According to Cornelia Wilbur and Richard Kluft, â€Å"MPD is most parsimoniously understood as a posttraumatic dissociative disorder of childhood onset. † Here the childhood onset and the presence of trauma are not parts of an empirical generalization or a statistically checkable fairly-necessary-condition. They are part of the psychiatrists` understanding of multiple personality disorder, part of what they mean by â€Å"MPD. † There is nothing methodologically or scientifically wrong with this. I warn only against having it both ways. There is a tendency (a) to define the concept â€Å"MPD† (or dissociative identity disorder) in terms of early childhood trauma, and (b) to state, as if it were a discovery that multiple personality is caused (in the sense of fairly-necessary-condition) by childhood trauma (Horton and Miller, 151-159). Moreover, child sexual abuse became part of the prototype of multiple personality. That is, if you were giving a best example of a multiple, you would include child abuse as one feature of the example. The connection between abuse and multiplicity became stronger and stronger during the 1970s, just when the meaning of â€Å"child abuse† moved from the prototype of battered babies through the full range of physical abuse and gradually centered on sexual abuse. As a point of logic it is useful to see how concepts are used to lift themselves up by their own bootstraps. Those sounds highly figurative, but consider this. In a 1986 essay Wilbur wrote, â€Å"In discussing the psychoanalysis of MPD, Mershkey (330) pointed out that childhood trauma is central and causal. † In fact he ended his prize winning essay by posing some questions. He said that in recent previous reports of multiplicity â€Å"childhood trauma is central and causal† (327-340). The connection between multiple personality and real, not fantasized, child abuse was cemented in clinical journals throughout the 1990s. By 1992 there were vivid musterings of data about the relationship between incest and multiple personality. Philip Coons (299) had stated in his classic 1994 essay on differential diagnosis of multiple personality, he wrote that â€Å"the onset of multiple personality is early in childhood, and is often associated with physical and sexual abuse. At that time no child multiples were known. But the hunt was on. The first in what is now a long series of books of contributed papers about multiple personality had a fitting title: Childhood Antecedents of Multiple Personality (311-315). Prevalence The number of different personalities per MPD patient has shown a substantial increase since the 19th century. During the 19th century, most cases involved only two personalities. Since 1944, however, almost all cases have involved three or more personalities. Modern cases average from 6 to 16 personalities per patient (Coons 305). For instance Modestin (89) reported that 44% of 74 MPD patients each had more than 10 personalities and 8 of these patients had more than 20 personalities each. North, Ryall, Ricci, and Wetzel (2003) plotted the mean number of MPD per patient as a function of year, between 1989 and 2000. In 1989, the average MPD patients manifested just fewer than 10 personalities; by 1999, MPD patients displayed an average of just under 25 personalities per patient. At the present time, MPD appears to be culture-bound syndrome. The explosion of cases since 1970 has thus far remained largely restricted to North America. The diagnosis is very rarely made in modern Europe, despite its turn-of-the-century prominence as a center for the study of MPD. It is also very rare in Great Britain (Modestin,90). Modestin (92) surveyed all of the psychiatrists in Europe concerning the frequency with which they had seen patients with MPD. Depending on how it was calculated, the prevalence rate ranged between . 5% and 1. 0%. More interesting, Modestin noted that 90% of the respondents had never seen a case of MPD, whereas three psychiatrists had seen each seen more than 20 MPD patients. Hence, the frequency of multiple personality has been debated over time. There were some descriptions of these behaviors early in this century, but from the 1920s to the early 1970s, there was a surprising dearth of cases (Spanos, 145). Kohlenberg (138) termed it relatively rare while other reports saw it as very numerous in number; more cases were reported from the mid-1970s to the mid-1980s than in the previous two-hundred years. The tremendous increase in reported cases has occurred almost exclusively in North America (Spanos, 147). This behavior pattern is rarely reported in Great Britain, France, and Russia; no case has ever been reported in Japan (Spanos, 160). In both North America and Switzerland, most diagnoses are made by a small minority of professionals while the vast majority of professionals rarely if ever see such a case (Modestin, 90-91). The dramatic increase in the reported numbers of cases has been attributed to differing factors. Possibly, cases which were undiagnosed in previous decades are now being diagnosed because of greater awareness of this condition; it has also been proposed that the condition is now being overdiagnosed in individuals whose behaviors are readily suggestible (American Psychiatric Association, 94). It is probably safe to conclude that the prevalence of Dissociative Identity Disorder is in dispute at this time; some may also dispute the validity of this diagnosis as the DSM-IV, unlike earlier versions of the DSM, does not provide any diagnostic reliability information (American Psychiatric Association, 99). Diagnosis On balance, with the behaviors labeled Dissociative Identity Disorder or DID hereafter, the variability between behavioral repertoires is very high, possibly so extreme that the repertoires do not compose one stable personality (Sapulsky, 64). The person himself or herself may even report being a different person, complete with a different name or identity. Although the behavioral variability is more extreme here, it is still on a continuum with the average person; we all can exhibit several personalities and there are circumstances under which any person might claim to be a different person (Sackeim Devanand, 21). Among the behaviors correlated with a diagnosis of DID, self-report is less controlled by public, environmental events and more controlled by events which are private to the person providing the self-report (Kohlenberg Tsai, 139). The most apparent question is: What type of experiences could account for this extreme behavioral variability, in the self-report of being a different person, with differences in sex, age, race, physical appearance, and so forth. Some writers report that this disorder may only become apparent to a professional or others when different people attend meetings, interviews, or therapy; that is, the same individual attends but with a different self-report of identity, memories, and personality (Sackeim Devanand, 25). In so doing, individuals displaying these behaviors can receive a great deal of reinforcing attention from professionals for engaging in these behaviors. Individuals displaying behaviors correlated with a diagnosis of DID may be reassured of no further abuse and may be encouraged to try to be themselves in as many ways as they can. The different self-reports and personalities become a source of gratification (self-reinforcement) for the formerly abused victims and the professional alike (Spanos, 153). The danger here is that a person with degrees of behavioral variability could be shaped iatrogenically to reporting to be a divergent person by professionals zealously looking for this disorder (Merskey, 329) To quote one skeptic, the procedures used to diagnose MPD often create rather than discover multiplicity (Spanos, 153). Pain complaints, paralysis, blindness, and so forth, also consist of a self-report of a private event. Each of these may be accompanied by publicly observable events such as wincing, reluctantly moving, reporting or appearing to be unable to move or see ( Skinner) Both the self-reports and the public evidence for these differences are under stimulus control of the different personality repertoires in cases of these behaviors. When such an individual displays a specific personality, the self-report of pain or other symptom comes or goes with the other behaviors. Originally, the public signs of pain were authentic afflictions in the past as the result of abuse; months or years later, such indications could be self-produced, rule-governed behavior as part of the personality repertoire. These pains and related behaviors could be reinforced and shaped into a real affliction by well-meaning others as the verbal behavior acquired differential stimulus control of operant pain behavior. The rep orts of pain and related behaviors can persist as operant behavior maintained by its consequences in the absence of the original painful stimuli (Bonica and Chapman, 732). As for the reports in the literature of allergic and other responses being present in some personalities and not others, these too can potentially be accounted for via verbal behavior mechanisms. There are reports that individuals can develop rashes, a wound or a burn or other physiological symptoms in response to anothers verbal suggestions, that is, under hypnosis, although it has been argued that many of these symptoms are likely self-inflicted when observers are not present (Johnson, 298). Actual reports of hypnotically induced dermatological changes are difficult to substantiate; such effects are difficult to produce and are not as common an occurrence as often reported (Johnson, 302). These reports are not all due to the acts of the person showing the symptoms; instead, these symptoms may be due to an interaction of verbal behavior and conditioning mechanisms. Verbal behavior can also facilitate the development of stimulus control via respondent or operant conditioning (Skinner). If an experimenter were to flash a light in your eyes and then shock you, the experimenter would expect you to come to recoil to the light after some number of such pairings. If the experimenter were to tell you that he or she was going to shock you after every light flash, then it would be expected for you to recoil to the light sooner. Relating this to the differential presence of symptoms is not a big leap. Here, the individuals who display the divergent personalities have self-instructed and subsequently conditioned themselves to display symptoms when performing different behavioral repertories. Over time, the symptoms may come under the stimulus control of the emotions displayed, in addition to the persons verbal behavior, and appear spontaneous to the person himself or herself. To support the argument for conditioning mechanisms producing somatic symptoms, Smith and McDaniel (69) showed that a hypersensitive cellular response to tuberculin was modulated by respondent conditioning. Individuals can also exert control over a variety of autonomic functions as diverse as dysmenorrhea to seizure activity, via biofeedback . Treatment From the foregoing assumptions, therapy for persons displaying the behaviors in question must consist of extinguishing a reasonable share of the behavioral variability in the repertoire and reinforcing behavioral stability and generalization; literally, to shape one personality. Kohlenberg (138) reported being able to increase the frequency of specific behaviors composing one personality of an individual who exhibited DID-like behaviors by differential reinforcement of that personality. When placed on extinction, these behaviors returned to baseline frequencies. Other techniques might involve the client role-playing and rehearsing several social interactions and experiencing some situations expected to produce normal emotional behaviors. Kohlenberg (139) reported success at reintegrating the personalities in a dual personality individual by teaching assertiveness skills via role playing. Caddy (268) also used assertiveness training and shaping in reintegration. The therapist might videotape client s as they behave, to use for feedback and in shaping and instructing more cohesive behavior. There might also have to be a way of teaching the client to engage in more social-referencing, or seeking public feedback in more instances of what is acceptable behavior. Whereas you or I might ask, Did you see (or hear) something? when we are unsure of seeing or hearing, individuals whose behaviors are consistent with the label of DID may have to learn to ask, Am I still behaving as me? The therapist could not answer this question alone but family members and significant others could. This process would have to continue until the person reports being the same individual with the same experiences, and has less observable variability in his or her personal repertoire. Even if a therapist were to try to undertake such an intervention, and most would probably not, this process could be long and arduous, due to the multiple sources of control that would require adjustment, and the possibly well-meaning sabotage by those who attend to and reinforce the variability. Indeed, based on this account, control of the behaviors in this pattern would be difficult for anyone to establish. Even the therapist who encourages variance is not exerting control unless unpredictable behavior is the target behavior. As a result, these individuals may have been and will likely be in therapy for years (American Psychiatric Association).

Summary of Chinns Four Ways of Knowing

Summary of Chinns Four Ways of Knowing Reaction to Chinns Four Ways of Knowing: Peggy L. Chinn, RN, PhD, FAAN is Professor of Nursing at the University of Connecticut. She earned her undergraduate nursing degree from the University of Hawaii, and her Masters and PhD degrees from the University of Utah. She has authored books and journal articles in the areas of nursing theory, feminism and nursing, the art of nursing, and nursing education. Her recent research has been focused on developing a method for aesthetic knowing in nursing, and defining the art of nursing as an art. Her book co-authored with Maeona Kramer has just been released in its fifth edition, now titled Theory and Nursing: An Integrated Approach to Knowledge Development. She is currently revising Peace and Power: Building Communities for the Future. This book is used worldwide by womens groups and peace activist groups as a basis for group process, consensus decision-making, and conflict resolution. She has been trained in the process of mediation at CDR Associates in Boulder, Colorado and provid es leadership and consultation in cooperative group processes. She is co-founder with Elizabeth Berrey of the Women of Vision Project, conducting workshops for women working together and facilitating networks among women creating change. In her book â€Å"Theory and Nursing Integrated knowledge development† Chinn has mentioned four patterns of knowing which are; Empirics, Ethics, Personal and Aesthetics. Chinn and Kramer have defined nursing art as a spontaneous, in-the-moment act that requires deliberate rehearsal. As Ethics emerges centrally in efforts to focus nursing practice and research, there also are renewed efforts to question and understand ethics at more foundational levels in the discipline, to understand who nurses are and on what values do they stand. Even within this holistic paradigm, however, the tensions between ideas of the individual and the individual-in-relation remain unresolved. In nursing practice, these tensions play out in competing ideologies, principles, ethics, values, and ideas in research, theory and practice. As a moral and philosophical base, caring has valued the being and knowing more than the doing in nursing. Caring can be seen as a moral foundation and an end in and of itself. As a professional ethic, caring must be a social commitment to work with others in ways that are connected, engaged, and meaningful. Even within this holistic paradigm, however, the tensions between ideas of the individual and of the individual-in-relation remain unresolved. In nursing practice, these tensions play out in competing ideologies, principles, ethics, values, and ideas in research, theory, and practice. Through critical and analytic reflection, nurses examine ontological and ethical foundations to their knowledge and praxis. It deepens and sharpens these foundations by forcing nurses to develop and act on commitments in the context of political or social agendas as well as to recognize that both their commitments and the agendas are constructed in and by a multiplicity of variable relationships of knowledge and power. Aesthetic experience matters in nursing because both patients and nurses are stakeholders in the situation. Experiences of illness have the potential to become lifted from ordinary life simply because so much is at stake. The details and nuances of relationships between patients and nurses are significant because they are part of this experience of illness and this is why the deeply engaged stance of caring matters. Without engagement, the nurse is no longer a stakeholder and nursing art is not possible. Engagement is a precondition of experience. Caring creates a world and that without care; the person would be without projects and concerns. Their view implies that care is fundamental to meaning and that meaning comes to be on the basis of some prior structure of care. A person may be regarded as constituted by their involvement and commitments In the world and without such engagements, one remains, in the profoundest sense, a mere possibility of a person. Similarly, the art must be loving; that is, it must care deeply for the subject matter upon which skill is exercised. An engaged, emotional commitment is a precondition for nursing art and effective intervention. In modern aesthetic theory, however, there is considerable controversy over whether there is a difference between art and craft.There is a principled difference between art and craft and argues for the necessity of making clear distinctions between them. Distinctions can be summarized by the following: craft results from skillful use of method or technique to produce a pre-specified product from some kind of raw material. Thus, the endpoint of a craft is visualized before the methods of achieving it are determined, so the way to proceed is planned from the beginning. Judging a work of craft is therefore less a matter of interpretation than a matter of fit between artifact and preconceived models of particular craft objects.Craft implies clearly understood goals and methods and this makes evaluation straightforward. The results of art, on the other hand, cannot be specified before creation; and means and ends are not always thought out separately. The artist does not always know what to make, or the most effective way to go about it; rather, ends and means evolve simultaneously. According to this definition, art is both more creative and difficult to evaluate. Chinn and Kramer have commented that art draws a person into new realms and expands perceptual capacities. If the object of nursing art is to transform the lived experience of health and illness, as Chinn claims, this explains why art is potentially so important for nursing. Not only do nurses need art to expand their perspectives on caring for patients, but patients also need nursing art to help them perceive the possibilities in their situation. A nurse who is artistically creative may set new standards for how things can be done. Art can change the ethos of what is considered good practice and alter the conceptions of what nursing outcomes ought to be. This means that the audience for nursing art will be not only patients and family members, to whom nurses hope to show possibilities so that they may move forward and transform their futures, but also other nurses, from whom nurses learn and with whom they transform practice. By maintaining a fluid openness in nursing situations, it may be that nurses own experiences and that of their patients is enlarged. One of the difficulties in defining this aspect of nursing art has been the invisibility of the art object. The process of art is visible enough in nursing. The tools, techniques, and craft-like approach can be described, but the outcome of the art is very difficult to specify. Nurse theorists are reluctant to identify the patient as the object of nursing art. It is contrary to their philosophical tradition to objectify patients in this way, nor would this identification be correct.

Believe in Love at First Sight Essay -- essays research papers

Well I use to believe that love couldn't be made at first sight. But yet now today I do think it happens. I will now share what I think love means. Love is affection, devotion, passion, desire, warmth, respect or loyalty. You choose. It doesn't really matter which one because they are all forms of love. Some are powerful and demand attention while others are more subtle and just below the surface. In recent years, love has drifted from these subtle levels to the more noticeable ones, namely passion. In my opinion, our society downplays the real necessity for genuine affection. By this I mean that we, as a society, spend so much time focusing on only one level of love (passion) that we tend to neglect and not recognize the need for closeness and trust (friendship). Love is an all-encompassing emotion that can be powerful and demanding, but also rewarding and pleasurable. Love is commitment. To love means to commit oneself without guarantee, to give oneself completely in the hope that our love will produce love in the loved person. Commitment can be called the backbone or building block of love. In other words, commitment is needed in order to build a stable and trusting relationship. Without commitment, love would not be able to grow and flourish. It can be extremely demanding on someone who isn't ready or sure that they want to commit to another person. I do have to admit that sometimes this can be extremely difficult and may leave one feeling a bit vulnerable. Commitment is the ability to take a risk and to accept the possibility of disappointment or pain. Again, I have to agree that commitment can be demanding, but to look on the bright side, it can also be rewarding. To be able to stay in ... ...t quench Love, nor floods wash it away." (Songs 8:7) Love is powerful and beautiful if one knows how to show and possess it. Granted it can cause problems, but it has answers too. To say that love is subjective would be an understatement, but in order to have it we must first look within ourselves. Love is having compassion for others, sharing feelings and your life with another person, as well as, having faith in others and forgiving those we love for the any errs that they may make. Most of all, we must be committed to those we love. Of course, this is only my opinion. No matter how long I try to explain what love is ultimately it is up to you, the reader, to define what love is to you. So let me leave you now with the words of the great Humanist Erich Fromm, "Can anything be learned about the art of love, except by practicing it?"

Electrolysis :: Papers

In chemistry, the production of chemical changes by passing an electric current through a solution or molten salt (the electrolyte), resulting in the migration of ions to the electrodes: positive ions (cations) to the negative electrode (cathode) and negative ions (anions) to the positive electrode (anode). During electrolysis, the ions react with the electrode, either receiving or giving up electrons. The resultant atoms may be liberated as a gas, or deposited as a solid on the electrode, in amounts that are proportional to the amount of current passed, as discovered by English chemist Michael Faraday. For instance, when acidified water is electrolysed, hydrogen ions (H+) at the cathode receive electrons to form hydrogen gas; hydroxide ions (OH-) at the anode give up electrons to form oxygen gas and water. One application of electrolysis is electroplating, in which a solution of a salt, such as silver nitrate (AgNO3), is used and the object to be plated acts as the negative electrode, thus attracting silver ions (Ag+). Electrolysis is used in many industrial processes, such as coating metals for vehicles and ships, and refining bauxite into aluminium; it also forms the basis of a number of electrochemical analytical techniques, such as polarography. Faraday's laws ============== Three laws of electromagnetic induction, and two laws of electrolysis, all proposed originally by English scientist Michael Faraday: Induction (1) a changing magnetic field induces an electromagnetic force In a conductor; (2) the electromagnetic force is proportional to the rate of change of the field; (3) the direction of the induced electromagnetic force depends on the orientation of the field. Electrolysis (1) the amount of chemical change during electrolysis is proportional to the charge passing through the liquid; (2) the amount of chemical change produced in a substance by a given amount of electricity is proportional to the electrochemical equivalent of that substance. Faraday's constant ================== Constant (symbol F) representing the electric charge carried on one mole of electrons.

SoftPot Rotary Potentiometer: Rotary potentiometer is provided at knee joint of the exoskeleton. Whenever the patient is having intent to walk, the rotary potentiometer calculates the respective torque. In response to that a feedback signal is provided to the actuation system to exert equivalent force to interact with the input torque. The feedback system is designed so well that it updates the status of input torque in fraction of a second and as a result exoskeleton keeps working accordingly; and works well with frequent torque changes. Rotary potentiometer works on the principle of resistance change. It is provided with a very fine needle/flip which rotates over the resistive ring. More the angle of rotation more will be the value of resistance observed between the terminal and the rotating flip. It is the measured resistance that tells about the angle of rotation of the joint and torques produced. Therefore, whenever rotational movement is observed the value of resistance of the respective potentiometer is changed and the signal is fed to the controller to take proper action. This helps in maintaining the exoskeleton motion according to the suggested profile and keeping it in the right motion. The rotary potentiometer used in our proposed design is SoftPot rotary potentiometer which is a miniaturized product with slim and sleek design. It can easily be placed along the bearings of the rotary joints and gives output in terms of analog electrical signals which are proportional to the angle of rotation. This sensor is very thin and compact in design with a wide range of operational resistances. Range of resistance change may vary between 100Ohms to 10,000Ohms; also the response of this sensor is much linear; therefore, the positi... ...e with a frequency rate multiplied by the movement. When you rotate the gyroscope, you may notice a so called Coriolis acceleration. In fact, the gyroscope is a spinner, rotating around a vertical axis, fixed in a frame which can articulate around horizontal axis, attached to another frame rotating around the third axis. Thus, we can conclude: no matter how rotate a spinner, it always has an ability to remain in the upright position. The transmitters accepts the signal about the spinner's orientation towards the frames, and the processor defines how the frame must be located with respect to gravity. Regardless to the types of stabilization the system, it can be the power system stabilization (used in two-stage gyroscopes), the tracer system stabilization force (also on a two-level gyroscopes) and the indicator system stabilization (in three-stage gyroscopes). .

Genetically Modified Foods Should Be Promoted Essay

Thank you members of the FDA for letting me speak today regarding the morality of genetically modified foods. Different bioengineering, better known as genetically modified, methods have been prevalent in modern society for almost half a century. It has allowed scientists to transfer genes that would have never been able to interbreed in nature but with the help from scientists, can breed as naturally (Harvard Law). The technology that describes this is known as biotechnology. When somebody is asked what are they afraid of, a common response might be, â€Å"I’m deathly afraid of spiders† or â€Å"I’m afraid of heights. I can’t look off the edge†. The response that is never heard is the unknown and I believe that â€Å"the unknown† is something that many people are afraid of. The unknown is simply a scary thing because it is impossible to tell the future. People say that cell phones may cause cancer, but in reality, this will not be known for decades and people surely will not stop talking on them. GMF’s scare people because they don’t know what the future holds. The future holds an agricultural revolution that could never have been predicted and will open many doors that were thought to not have existed. The United States federal government should promote the purchasing of genetically modified foods by the public that can be done by educating the public with the benefits of genetically modified foods In a poll done by ABC regarding the skepticism of genetically modified foods, 52% of people believed them to be dangerous and 13% were unsure about them (Poll). The public should not be so confused regarding the safety of the food that they eat on a daily basis. The majority of all cultivated food has been genetically modified in some way by the time of its production (Harvard Law). This means that the public eats genetically modified food every single day without knowing it. If the public was to be better informed about GM foods then they would support them. The public really does not know so much about the technology surrounding bioengineered food. Biotechnology can be defined as the genetic manipulation of organisms for a common goal, in this case, food. Genetic engineers have successfully been able to introduce methods to be able to combine genes of species by selecting certain genetic material from each organism. This results in a new organism that contains traits of both preceding organism (Harvard Law). A solution to the unawareness of the United States’ public would be to advertise the benefits of genetically modified food. If the public were more educated on the topic of genetically modified foods they would support it because the advantages outweigh the disadvantages. The government needs to introduce a series of advertisements regarding GM foods. Every man and woman in this country has the ability to vote for who they want, say what they want, write what they want. Although not written in the constitution, all people are also given the right to eat what they want. Whether cheap, expensive, healthy, or unhealthy, we are all given the choice to make those decisions for ourselves. In a poll done by ABC news asking if people would be more inclined to buy genetically modified food, 57% said they’d be more likely to purchase untouched food (Poll). If the federal government were able to make the public more aware of the advantages of genetically modified foods people would be more inclined to buy them and support the industry. As of now, the public chooses non-GM foods over GM foods. They need to be introduced to the positive aspects of bioengineering. If the federal government wants to revolutionize the agricultural industry, consumers need to be in favor of GM foods. If more than half of the consumers said they’d be less likely to purchase GM foods then how can food companies put GM foods on the shelves of super markets knowing that not enough will be sold? Little does the public know, but about 60-70% of processed foods do contain genetically modified ingredients (Web MD). The FDA states that there is no new safety concerns introduced into the food (Harvard Law). The FDA’s purpose is to deem food safe or dangerous and whether or not the public should be eating it. The FDA constantly argues that there are no safety risks when eating GM Foods. The public needs to trust them on this topic just like they do with all other foods. As previously stated, most people are scared of the unknown, and in order to make this industry a well working one, consumers need to be in favor of genetically modified food. Genetically modified food is safe. People are eating GM food at every meal and there have been no outbreaks of any diseases related to the introduction of GM food. Genetically modified food is the future. In developed countries, crop yield was increased by 6% and in undeveloped countries; crop yield was increased by 29% (Wikipedia). A very well known example of a genetically modified food is golden rice. It was introduced to the world as a solution to the extremity of morbidity from lack of vitamin A, iodine, iron, and zinc. The lack of these fundamental dietary components is the root cause of disease worldwide. Golden rice offers a solution that contains these lacking components. Many things can be made possible in the future with an increase in support for genetically modified food. If scientists were able to create a gene that could be put into all cultivated crops that would allow them to grow throughout the winter, they could end world hunger. World hunger being solved would mean one of the utmost impossible puzzles has been solved. The two things that most people would likely to fix in this world are world peace and an end to hunger worldwide. No this government can’t solve world peace. Yes this government and others do produce enough food to feed the every human on this planet. However, if enough cheaply grown crops were produced throughout the whole year, governments will be more inclined to try to feed the world. With climate change being a really evident effect from global warming, it is nearly impossible to predict what Mother Nature holds in store for mankind. With the technology available, the United States’ government must issue out more patents for scientists to increase and continue the research surrounding GM foods to make them the food of this world. The government should and would only issue out more patents to scientists if the United States’ consumers would buy GM food and support the industry. This is the sole reason that this federal government needs to make aware the public, of the advantages from GM foods.

Theories of Psychological Development

Developmental psychology is the scientific study of human changes across their life span. It is important to study psychological development to understand how and why people go through certain changes throughout their life. There are many different areas of psychological development. Two main areas are perceptual development and emotional development. They both have theories that can be related, but before you can understand the relations, you must first understand the two theories. The theory of perceptual development was created by an American Psychologist named Eleanor Gibson. It states that perceptual development is the process of an infant exploring its constantly changing environment and deciding what to do and how to act with the newly found information. Affordance exploration is also a key feature of perceptual development. Gibson believed that affordances are visual clues to the functions of an object. An example could be a person climbing a ladder. The infant could examine how the ladder needs to have a stable base and lean against a certain object to keep from falling down. When affordances are found, differentiation starts to occur. Gibson’s definition of differentiation is basically the ability to discriminate different environments. If you look back at the ladder example, the infant uses affordances to see the ladder needs support to stay upright. Then the infant uses differentiation to see a person is more safe standing in the middle step of a ladder than the top step. As the infant experiences more and ages, it becomes better at differentiation. Emotional development is based around a theory called the attachment theory which was created by a British psychiatrist named John Bowlby. The attachment theory is the act of developing an affectional bond with someone who is considered a caregiver (Bowlby’s definition was â€Å"a lasting psychological connectedness between human beings†). It is crucial for a child’s behavior in the present and future to have an attachment relationship with a caregiver. Bowlby stated that for an attachment to be strong, four characteristics need to be present: proximity maintenance (the desire to be in the presence of the caregiver), safe haven (returning to the caregiver when feeling unsafe), secure base (considering the caregiver as a source of security) and separation distress (feeling anxious when the caregiver is not present for an extended period of time). Bowlby believed that strong attachment relationships develop after the caregiver and child become closer. Mary Ainsworth (a previous student of Bowlby) was an American Psychologist who believed that there are three types of attachments: secure, avoidant and resistant. A secure attachment is formed when the caregiver is used as a safe home and the infant feels less safe when the caregiver is absent than when they are present. An avoidant attachment is basically the opposite of a secure attachment. It is when the caregiver is considered a stranger by the child and they try to avoid the caregiver as much as possible to feel safer. A resistant attachment is a lot more complex than the other types of attachments. It occurs when the caregiver is unresponsive to the child’s needs making them feel unsure what they want or need which makes them feel unable to count on their caregiver. There are some relationships between the theory of perceptual development and the attachment theory. According to the two theories, both require a responsible caregiver for a child to have a proper and healthy development to be able to experience affordances and to have the right caregiver provide the environment to do it in. Also, your caregiver could be responsible for a child not learning certain affordances which could affect them in their future life. Another way to look at it is if a caregiver never provided the chance for the child to experience affordances related to a job that requires experience in, say, the construction industry, then they will struggle psychologically in the future to earn that job or any job that they may want. Perceptual and emotional development are both very important to a child’s psychological development. It is important to understand the two main theories behind them to learn what is required for a child to develop healthy and normally to live the life that they want to live.
