Wk2 disc(6100) - Essay Example This is necessary as theories serve as maps which guide the counsellor as to the handling of the client. Each theory provides the MHC with direction and goals for the clients and helps in evaluating the effectiveness of counselling. MHC’s emphasise the patient’s environment with a comprehensive perspective to treat dysfunction or any pathological condition if necessary. (Hershenson & Strein, 1991) Five different theoretical approaches are psychoanalytic, behavioural, client-centered, cognitive and affective. The basic premise of client-centered theory is that each person has an inherent tendency to develop all capacities to maintain and enhance oneself. Thus the aim of this theory is to bring the client towards self actualization. The MHC using this approach assumes the role of being a genuine and empathic friend towards the client sharing experiences and working to build the clients confidence, which in turn helps in positive changes in the clients self awareness and attitude. This particular approach requires a personal touch that is lacking in many lives of today’s fast paced world. I personally gravitate towards this theory as it coincides with my belief that connecting to each other at a personal level is important to nurture the human psyche and is the missing element and cause of many of present day mental health problems. (Vacc and Loesch, 2000) One common trend in counseling is that of eclectics and integration. That is a combination of methods is used to treat the patient depending on his particular requirements. The transtheoretical model (TTM) is a practical approach that combines eclectics and integration. TTM provides an integrative structure to counseling theories. It is developed to combine various aspects of counseling without detaching practice from theory. (Petrocelli, 2002) TTM is useful in many situations especially for workplace counseling, youth counseling as in educational institutions etc. A major reason for

The functional organisation of the visual system

The functional organisation of the visual system The aim of this essay is to describe the organisation of the visual system in relation to its specific functions. In order to perform essential functions, the visual system is faced with many computational problems needing to be solved in order to maintain effective visual perception. This essay aims to describe one such computational problem the visual system must solve; colour constancy. If light coming down from the sky changes colour, the perceived colour of objects should also change, however this is not the case. The nervous system is highly involved in the process of maintaining effective colour constancy and this essay aims to look into how colour constancy is achieved in the nervous system. The first part of this essay will outline the functional organisation of the visual system, focusing on the general anatomical organisation, the retina, lateral geniculate nucleus (LGN), organisation of the cortex and parallel and hierarchal processing. Focus will then be on the chosen co mputational problem of colour constancy and the importance of the visual system maintaining successful constancy of colour. The next issue will be to assess how colour constancy is achieved within the human nervous system, focusing on the functional specialisation of the cortex, cone receptors and retinal involvement in attempt to understand how colour constancy is maintained in the nervous system. The visual system is part of the central nervous system and includes the eyes, connecting pathways to the visual cortex and different parts of the brain that collectively allow for sight. The visual system must convert patterns of light that fall onto the retina into perception. Initial visual processing takes place within the retina, with the preliminary aim to convert information about luminance into information about contrast (Kuffler, 1953). All in all the visual system works by the rule of relative qualities, i.e the luminance of an object in relation the luminance of its surrounds. These relative qualities and comparisons take place within the retina. The retina contains two kinds of photoreceptors (rods and cones) that absorb light and send signals to bipolar cells, which are connected to ganglion cells that send information to the LGN. The LGN has six layers; four parvo-cellular layers and two magno-cellular layers. Ventral to each of these layers is a thin kinocellular layer. Parvo-cellular cells and kinocellular cells play a role in colour vision. Therefore, initial colour vision takes place within the retina, with cone photoreceptors being specialised for colour processing. It has been found that there are three types of cone receptors within the retina which are sensitive to different wavelengths of light; short wave length light (blue light), medium wavelength light (green light) and long wavelength light (red light). Colour detection is perceived largely by the relative activation of the short, medium and long wavelength cones. The trichromatic theory of colour vision proposed by Young-Helmholtz (1800/1867) is a predominan t theory into colour perception. Cone cell receptors contain light-sensitive photo pigments which allow them to respond to light and create colour vision. Young-Helmholtz theory proposed that we have one cone type most sensitive to short wavelength light (blue), one most sensitive to medium wavelength light (yellow/green) and finally one most sensitive to long wavelength light (red). It is the relative activation of each cone type that results in the perception of colour. Another dominant theory into colour processing has come from Herings (1878) opponent processing theory. Hering argued that there are three types of opponent processes within the visual system that account for colour perception. One opponent process results in the perception of red at one extreme and green at the other extreme. Another type results in perception of yellow at one extreme and blue at the other. The final opponent process results in perception of black at one extreme and white at the other. Hering argu ed that it is the ratio of activation along these opponent processes that accounts for colour perception. Opponent cells have been found within the LGN, which provides functional evidence for the involvement of the LGN in colour vision. There are red/green colour coded cells and yellow/blue colour coded cells within the LGN which are essential for colour processing and colour constancy. However in essence the function of the LGN is to pass signals from the retina to the cortex rather than to process them. Another important functional part of the visual system is the visual cortex, which contains cells that respond to wavelengths coming from an object in relation or comparison to wavelengths coming from surrounding objects. This comparison is essential in the analysis of colour. The visual cortex contains many layers of cells, with colour, form, movement and disparity being dealt with by separate groups of cells. It is divided into sub-layers; IVA, IVB, IVCÃŽÂ ± and IVCÃŽÂ ². Cells in the parvo-cellular layers of the LGN, dealing with colour, project to layers IVCÃŽÂ ² and IVA, thus showing the functional organisation of the cortex. In the secondary visual cortex (V2), cells dealing with colour, form and disparity are also kept separate. V2 processes properties such as colour and brightness. V4 deals particularly with colour and form. The visual cortex is organised into a columnar form. The similar properties of the cells within the cortical column are most likely due to the arrangement of anatomical connections. There have been found to be columns dominant for colour and orientation of edges. According to Zeki (1977) within area V4 there are separate columns for red, green and blue perception. Thus showing the visual cortex is organised on the basis of functions. One factor that has been made clear is that different features of a visual stimulus are dealt with in parallel processes within the visual system. The features of colour are kept separate through at least three levels of processing; V1, V2 and V4. However it has been found that within these parallel processes, hierarchal processing occurs. Dew (1984), has provided clear evidence for a hierarchy of cells types within the colour system. Photoreceptors join onto opponent colour cells which respond to some wavelengths and not to others. The visual system is functionally organised to overcome many computational problems, one of which is colour constancy. Colour constancy is a tendency for a surface or object to appear to have the same colour when there is a change in wavelength contained in the illuminant. (Eysenk, 5th edition). The phenomenon of colour constancy indicates that colour vision does not depend only on the wave length of reflected light. The problem involved in colour constancy is to assign colour to a scene in the ambient light (spectral reflectance) (Maloney, 1985). Spectral reflectance is the percentage of light at each wavelength a specific surface reflects. As the illuminant power varies, the light reaching the eye also varies. However the percentage of light a surface reflects (due to its physical properties) does not change. The function of colour constancy is to discount the illuminant and recover information about surface spectral reflectance. Marr (1982) claimed that there must be an extra leve l of perception and processing. Light is reflected off objects with a fixed percentage of energy at each wavelength (surface spectral reflectance) and some of it enters the eye of the observer where is it selectively absorbed by cone receptors. The maintenance of colour constancy is achieved in the nervous system in various ways. The functional specialisation of the cortex is one way in which colour constancy is achieved. Zeki (1992, 1993) argued that different parts of the cortex have different and specialised functions. V1 and V2 have been found to have inputs in early stages of visual perception. Both cortical areas contain specialised cells responsive to colour and form which process these properties and relay signals to specialised visual areas, (Zeki, 1992, p47). V3 and V3A have been found to be responsive to form and shape but have no input in colour processing. V4 however has been found to be responsive to colour and combines connections from temporal and parietal cortex, (Baizer, Underleider and Desimone, 1991). Zekis critical assumption was that colour and motion are processed in anatomically distinct parts of the visual cortex. Lueck et al (1989) have provided supporting experimental evidence of the anatomically distinct processing of colour. They presented coloured or grey squares to observers. PET scans showed 13% more blood flow within area V4 when presented with coloured stimuli, other areas were found to be unaffected. On the other hand Wade, Bewer, Rieger and Wandell (2002) used FMRI and found areas V1 and V2 were also actively involved in colour perception. Zeki (1983) has provided evidence for the involvement of V4 in promoting colour constancy. Zeki found that within monkeys, certain cells in area V4 responded strongly to a red patch in a multicoloured display illuminated predominantly by red light. These cells did not respond when the red patch was replaced by green, white or blue patches, even though the dominant reflected wavelength was red. Therefore these cells respond to the actual colour rather than the wavelength reflected from it and has a role in the process of colour constancy. Lesions in area V4 have been found to impair colour constancy while other aspects of colour vi sion are unaffected, (Heywood and Cowey 1999). The cortical area of V4 has argued to be able to distinguish differences between surface colour and colour of the illuminant thus being important in achieving colour constancy. Land (1977) retinex theory argues that both the retina and the cortex are involved in visual processing. The basic assumption of this theory is that we decide the colour of a surface by comparing its ability to reflect short, medium and long wavelengths against adjacent surfaces. When comparisons cannot be made, colour constancy does not occur. The three types of photoreceptors in the retina absorb light; each level of activation within each cone receptor is compared to that of others. Kraft and Brainard (1999) conducted a visual experiment in a box which included a tube wrapped in tin foil, a pyramid and a cube as well as a Mondrian stimulus. When all objects were visible, colour constancy was high (83%), even with changes in illumination. Progressively removing the cues decreased colour constancy. The most important factor in maintaining colour constancy was local contrast, involving the comparison of retinal cone responses from the target surface with that of the immediate backgro und. Colour constancy dropped to 53% when local contrast information was not available. Also global contrast was important; the retinal cone responses from the target surface are compared to the cone responses of the whole visual scene. When observers could not use global contrast colour constancy dropped from 53% to 39%. This therefore indicates that we need to know about lots of different stimuli in the visual scene if we are to calculate what the illuminant is like, discount it and achieve colour constancy. Photoreceptors have therefore been shown to be heavily involved in colour constancy which provides evidence for the involvement of the nervous system. Young-Helmholtz (1800/1867) trichromatic theory of colour vision and Herings (1878) opponent process theory outlined previously in this essay provide evidence that photoreceptor cone cells within the retina are heavily involved in colour perception and constancy. Shepard (1990) stated that the trichromacy of human colour vision is a reflection of the three phases of natural light/illumination; light-dark light, red-green light (low sun) and yellow-blue light (poor illumination and sky light). To achieve colour constancy on the basis of their surface reflectances, the visual system must discount perceptually for the three types of variation in illumination. Shepard (1990) and Maloney and Wandell (1986) argued that trichromacy of the visual system allows for colour constancy. In conclusion it has been shown that the visual system is highly organised on a functional basis. The visual system is faced with many computational problems which it must solve. Evidence that functional specialisation of cortical areas, cone receptors and the retina are methods for which the nervous system uses to overcome the problem of colour constancy. Word Count: 1992.

Analysis of After Great Pain A Formal Feeling Comes by Emily Dickinson :: essays research papers

In After great pain, a formal feeling comes(341), Emily Dickinson offers the reader a transitus observation of the time just after the death of a loved one. Dickinson questions where one goes in the afterlife asking, 'Of Ground, or Air' or somewhere else (line 6)' We often remember those who die before us, as we ourselves, as morbid as it may be, with everyday, are brought closer to our own deaths. As used in most of her poetry, she continues in iambic meter with stressed then unstressed syllables. Dickinson, however, straying away from her norm of 8-6-8-6 syllable lines repeating, uses a seemingly random combination of ten, eight, six, and four syllables, with the entire first stanza of ten syllables per lines. Line three lends itself to ambiguity as Dickinson writes, 'The stiff Heart questions was it He, that bore,' he, refers to the heart, yet she doesn't specify exactly what he bore. Dickinson refers to the Quartz grave growing out of the ground as one dies, lending itself to a certain imagery of living after death (lines 8-9). Although the poem holds no humor, she stretches to find what goes on after death. As we get to the end of the process of letting go of the one dying, Dickinson reminds us of the figurative and literal coldness of death. The cold symbolizes an emotion and lifeless person as well as the lack of blood circulation. Bringing reference her off syllable lines, the author of Dickinson's Fascicles, says the first stanza is held together by the structured iambic pentameter, in addition to using rhyming couplets as in, ?Bore? and ?before.? Due to Dickinson?s submergence in nature, she emphasizes organic matter, with both her use and capitalization of ?Heart? and ?Nerves.? Although she draws attention to those of which are organic, she shifts to emphasize those of which are inorganic, for those of ?Ground,? ?Air,? and ?Quartz.? Analyzing the two four syllable lines, ?A Wooden way/Regardless grown? (7-8), the way can be viewed as an insincere mourning path that society attempts to set individuals toward to cope with their emotions during troubled times. Wood, even though an organic matter is used negatively here to describe an artificial reconstruction of this natural element into a coffin. Looking further at an inorganic element, quartz, it signifies the sharp pain of a loss.

Death, Tragedy and Community at Wartime Essay

Dying in War: Implications for the family, the community and the social worker Death is a phenomenon that evokes mixed reactions and views from a community. For some, it a blessed release from the trials and problems of life. To others, it may very well be the end of the world when they lose a loved one. What remains constant however is the grief, bereavement and loneliness experienced by those left behind. Even more so when death was sudden and unexpected as like what happens in times of war, disaster, and terrorist attacks. Grief goes through many stages, each stage more difficult that the last. While most people generally manage to cope with time, some experience more difficulties and tend to develop psychological and emotional problems. During the First and Second World Wars, the knock of the postman was a thing of dread. They either brought telegrams summoning the sons and fathers of families for the draft or telegrams announcing the death or loss of loved one. An estimated 8 million military personnel in 14 European countries were killed in World War I, and 14. 4 million military personnel in 17 European countries were killed in World War II (Aiken, 2001, p. 111). Parents who suddenly lose their children such as what happened to most wartime mothers with adult sons usually have a harder time coming to terms with the death of their child (Gilbert, 2005, p. 6). The loss and feelings of helplessness and anger can be intense. There is a common belief that something is wrong when a parent buries his/her child. Most parents who have experienced this report that they feel dissociation with life and everything just felt so unreal (p. 6). That it is not right that parents should survive their children is often the thought that haunts bereaved parents. What role do social workers play in times of war and terror? Social problems are defined as the challenges that face and exist in communities (Hardcastle, Powers & Wenocur, 2004, p. 62). It is the social worker’s job to help the community and its members formulate and implement solutions to these problems. Social workers usually work with problems related to economic disadvantages, illness and disability, crime and delinquency, abuse and maltreatment, service provision to special parts of the population and mental illness. All these problems call for leadership attention and trained intervention (p. 62). No situation can put all these things together more than times of war. What may be the biggest challenge to a social worker though is the task of helping a family and community deal with the sudden losses of loved ones in combat. In addition to this, they should also be prepared to cope with the rehabilitation of those who have been able to come back home but exist with scars that are not only physical but also mental and emotional. The events of September 11, 2001, though technically not a part of any formal war except the one on terror, had an impact that was not dissimilar to armed conflicts. There was confusion, anger, anxiety and above all, people who in an instant lost their loved ones. As with wartime, sudden death can only be viewed as unfair and untimely (Clements, Deranieri, Vigil & Benasutti, 2004) For example, the September 11, 2001 terror attacks left behind families and children who have lost moms and dads in that instant. Even adults and children who were indirectly affected by the attacks have grown to suffer feelings of anxiety and shattered security in their personal and familial safety (Smith & Reynolds, 2002). Besides the inevitable feelings of grief, children especially were left behind and often had to contend with nightmares and morbid pictures of the traumatic deaths their loved ones experienced as well as the stress and difficulty of trying to picture lives without mom or dad. It is also important to remember that the effects of trauma are not limited to those who suffer it directly (Sims, Hayden, Palmer & Hutchins, 2000, p. 41) The ubiquity of television also afforded children at home not only news of the attacks but also vivid pictures and descriptions of the tragedy and all its violence. This made it even more problematic for children and people who have lost loved ones in the Twin Towers and the plane crashes as coverage of each horrific scene gave them fodder for the imagination and subsequent nightmares. The case of a 7-year old boy named Johnny is cited in the study (2002) by Smith and Reynolds. : Following the 9/11 attacks, Johnny developed a constant fear of his parents leaving home and getting killed by â€Å"bad men. † He also developed a phobia of elevators and would throw tantrums whenever his parents tried to make him use one. Johnny admitted to his therapist that his fear of elevator stemmed from a story he heard of how â€Å"people in the Twin Towers were trapped and killed while riding in the elevators. † (Smith & Reynolds, 2002) Neither Johnny nor his family were directly involved or affected in the terror attack. The mental and emotional strain suffered by survivors and those affected by this very high profile event led to the American Psychiatric Association’s setting up of counseling services â€Å"focusing on grief, acute stress and Post Traumatic Stress Disorder (PTSD) (Smith & Reynolds, 2002). The difficulty that most surviving relatives meet is in the un-timeliness of death. While conventional wisdom holds that sons and fathers who go to war may not come back again, more often than not, there is a strong hope that they will be able to come home. Despite the knowledge of all the possibilities, the sudden and traumatic nature of death often creates problems among surviving relatives. They become victims in their own right. Muller and Thompson believe that the manner of death plays a vital role in determining the reaction of the survivors (Muller & Thompson, 2003). If its bad enough for people to suddenly lose their loved ones, how much more would it be for children to live and go through an environment of war and death? In his article in the Journal of Multi-cultural Counseling and Development in 2004, Clinical psychologist and Fellow of the American Psychological Association (APA) Gargi Roysircar relates the case of 20-year old Yugoslavian emigre Stephen, who at the age of 10 witnessed the height of the civil war between Christians and Muslims in Kosovo in 1990. In interviews with his counselor, Stephen recalls witnessing about 80% of his classmates get killed by bombs, sniper shots and gunfire as they walked to and from school. At age 14, Stephen was taken by his father to the frontlines for training in combat to fight with the Serbian army. The next two years wold take Stephen all over the Balkans and would expose him to all kinds of death, privation and war atrocities. Eventually migrating as political refugees in the United States, in 1999, Stephen demonstrated difficulty in acculturation and adjustment. The constant displacement he experienced in war along with the mistrust bred by his past and cultural paranoia fostered by the Croatian community they lived with made it difficult for Stephen to acclimatize to peacetime setting. Roysircar describes Stephen as having â€Å"recurrent thoughts and images of his violent experience in the Balkans. He experienced nightmares, hostility and a profound sense of a lack of belonging. Stephen also often recounted the difficulties he experienced including â€Å"hiding in a basement and eating rats† especially when angry. He also displays a deep-seated hatred for the Muslims and believes â€Å"the Middle East should be wiped off the face of the Earth† (Roysircar, 2004). While there may be models detailing stages of grief and recovery, social workers must be prepared for instances that do not adhere to such models. In Stephen’s case while he did not directly lose any of his close family members, he was exposed at an early age to violence and death. He has also experienced being the cause of another human being’s death as he and his father fought on the Serbian army. This is no different from the Post-Traumatic Stress Disorder exhibited by American soldiers returning from Vietnam or any other area where they fought in combat. A person does not have to lose anyone in order to feel grief, bereavement and suffer any disorder that may result from it as evidenced by the little boy Johnnie and Stephen. Death in wartime is not limited to just the loss of a loved one. In a community where all able bodied men are called to arms, anybody can lose husbands, brothers, fathers and sons at any day. Families left behind are left to their own devices and imaginings of what horrors their loved ones are facing. Those who do lose family members are haunted by the manner by which their loved one died. There is also the unfortunate circumstance in war where death is an ambiguous issue. In the Vietnam War, many people were reported missing in action. The families of such people were left at an awkward and horrible position of not knowing whether they should be mourning or holding out hope for their loved one’s return (Worden, 2003, p. 40). In some cases, some families do accept the reality that their loved one may be dead and go through the entire process of mourning and recovery only to be told later that their husbands and sons were simply prisoners of war and has since been released. While ordinarily this may sound like a fairy tale ending, there may come unbridgeable gaps and tension that can only ruin relationships and lives (p. 85). On the other hand, some families may keep clinging to the hope that their loved ones are alive and therefore refuse to give way to grief and acceptance. Stacy Bannerman (2007) is one of the many army wives whose marriage was broken up by war. In her article that appeared in â€Å"The Progressive,† she relates how her once happy marriage with one of the military’s mortar platoon commanders started heading downhill with every death he caused and witnessed during his stint in Iraq. She decries the insensitivity and lack of support for military families from the National Guard. She further cites how there was an absolute lack of prompt attention to the mental and emotional needs of returning military men who more often than not suffered from PTSD like her husband, Lorin did. Because of this, there have been military men who have survived their tour of duty only to succumb to mental and emotional anguish and end up committing suicide on American soil (Bannerman, 2007). It is the soldiers, their families, and the people of Iraq that pay the human costs. The tab so far: more than 3,000 dead U. S. troops, tens of thousands of wounded, over half a million Iraqi casualties, roughly 250,000 American servicemen and women struggling with PTSD, and almost 60,000 military marriages that have been broken by this war (Bannerman, 2007). The problem here is that most of those left behind are left to cope with their own fears without the support of anybody else except family and members who are also wrapped up in their own concerns. In this case, social workers must be able to take the lead in establishing outreach and community groups so people do not have to cope and suffer in isolation. Carpenter (2002) states that the psychological well-being of the members of a community is one of the jobs of a social worker. While it is true that the trauma brought on by exposure to violence and death may be an individual process, healing and recovery needs societal support and strong relationships (Carpenter, 2002). This may become a challenge to families and communities who are dealing with their anxiety and grief. However, Carpenter reminds social workers that one of the primary goals of social work is to help empower the oppressed. Oppression in itself can take on many definitions and forms. In this particular case, it is the trauma and grief that is debilitating and oppressing the individual and the community. Social workers must also be prepared to look for signs of repressed grief. Some individuals choose to withhold and fail to express grief and therefore develop problems later in life often developing manias, paranoia and demonstrate abuse towards other people. At times, the feelings of grief or multiple losses of loved ones may lead to a â€Å"grief overload† that would cause an individual to delay grief (Worden, 2003, p. 91) The community as a social system can provide a network of support. Given the right leadership, empathy and sensitivity, it can also become a â€Å"safe† place where people can come to terms with their grief and slowly move on toward recovery. In the cases of Johnnie and Stephen, it took time before they were able to face and admit their anger, anxiety and grief at the bad things that they experienced and fear. Sometimes, self-reflection and a ready ear is all that’s necessary. As clinically trained counselors and diagnosticians, social workers are tasked with the duty of helping people recognize and understand what problems they may have. Community-wise, social workers should have enough knowledge of the community’s demographics in order to unify and create a solid network of safety and interaction that may assist troubled and grieving individuals particularly in conflict filled times such as war. Death at wartime comes in many forms. It could be the actual death of a loved one, anxiety at the possible death, loss at whether somebody is dead or not, or even those who continue to physically live but have broken spirits and permanent disabilities as a result of war wounds. Much as death is a big thing that affects not only the family but also the community as a whole, war brings with it so much more problems and issues that will undoubtedly challenge most social workers. Undertaking social work means one must be in sync with the community. By in sync, it covers everything from issues, key people, and resources that may be mobilized in times of need. War is a time of immense crisis and tragedy that the social worker must be prepared to face head on and ably lead and facilitate the processes by which the community may be transformed into a supportive societal system that each member may be able to depend on. This does not mean however that social workers cannot be affected or lose their sense of self in dealing with all these tragedies. Tsui and Cheung (2003) recommend a self-reflection on the part of the social worker in order to understand and come to terms with their own reactions and feelings to tragedies they both witness and hear about from their clients before attempting to deal further with the grief of others. They also stress that once social workers attend to their duties, they should do so intellectually yet with empathy and focus on assessing and addressing the needs of the community rather than one’s own (Tsui & Cheung, 2003) References Aiken, L.

My First Real Experience With Biometrics

My first real experience with biometrics occurred when my son purchased a new cell phone nearly two years ago. During the initial setup, he selected an iris scan as his passcode. I was a little surprised by the technology and skeptical of the convenience and security. My first question to him was, â€Å"What if someone needs to get in your phone?†. He quickly replied, â€Å"That is what the security feature is for, so they can't get in. If I want them in it, I'll open it and hand it to them.† He is an active duty Navy sailor. He explained to me that he felt more secure knowing that no one could break into his phone because of this passcode. I observed him over the next two weeks while he was home on leave. Each time he accessed his phone, he simply looked into the screen and instantly he had access. He has shared that when others see that his passcode is an iris scan, they realize they cannot hack into the phone. Most never attempt anything at this point. Those that do are not successful. To this day, he has not had any security issues with his phone. Watching the success and ease at which biometrics worked with a cell phone, I moved to a biometrics passcode when I purchased a new computer earlier this year. My new computer came with FastAccess Facial Recognition. After initial setup which included some training to recognize my face, I no longer had to enter a password or PIN. .There are advanced features that turn off the webcam, enable parental controls, and enable an automatic login feature that make FastAccess safe and user-friendly. When someone else tries to access my computer, access is denied because FastAccess does not recognize them. I've been told for many years that my daughter could pass as my twin, but the computer knows better, it would not unlock for her. Lighting can affect the process, the system does not work in poor lighting conditions. In these cases, I am prompted for a second form of authentication, a PIN or password. Other than this, I have been very pleased with not having to use a password to access my system and knowing my data is secure. Now that I was familiar with biometrics in â€Å"my† environment, I wanted to learn more about biometrics in the area of health information, an area I have worked in for nearly thirty years. According to Whitman and Mattord (2018), biometric access control refers to physiological characteristics used to authenticate identification that has been provided. This control relies on recognition, comparing an actual image to a stored image. Fingerprints, palm prints, hand geometry, facial recognition, retinal prints, and iris patterns are types of biometric authentication technologies. The three characteristics in humans that are generally considered unique are the fingerprints, the retina, and the iris (pp 334-335). Iris recognition provides the highest level of accuracy of all biometric markers. According to Katz, the algorithms used in iris recognition are so accurate â€Å"that the entire planet could be enrolled in an iris database with only a small chance of false acceptance or false rejection† (2002). Concerns in the area of biometrics are â€Å"false negative† and â€Å"false positive†. When an individual has a false negative their identity is registered within the system but for some reason, the system does not recognize them. A false positive is the larger concern. This rating means the individual is not registered within the system, yet the system is recognizing them as another registered user and providing access to them based on that recognition. Facial recognition technology opens the door to many possibilities in healthcare, particularly in the area of health information management. This technology has been widely discussed as part of the national patient identifier initiative. Facial recognition is a preferred technology over other biometric techniques because it does not require direct contact with the patient and it is easily deployed. Some of the uses for facial recognition in the health information management area allows for authentication of proper security clearance for employees to grant or deny access within the EHR to staff without a password or PIN. By authenticating your employee, you are maintaining the confidentiality of the protected information. The same technology can be used to verify or authenticate the identity of a provider when they access controlled substances. Facial recognition is the preferred technology because â€Å"some areas within a hospital zones require clinicians to wear surgical gloves and masks, thereby prohibiting the use of fingerprint authentication† (Callahan, 2017). Another option is a feature where â€Å"a patient's image can bring up their file in the EHR using facial recognition software† (McCleary, 2016). This security feature allows the healthcare provider to compare their patient to the stored patient image. Authenticating the patient allows you to maintain the integrity of your data, minimize medical mistakes and improve patient safety. Additional bonuses will be cost savings by reducing fraud, and improved protection or security of confidential patient heath information. There are yet additional benefits of facial recognition to the medical arena. One benefit is the prevention or reduction of medical identity theft. Medical identity theft occurs when someone uses another individual's information to obtain medical services for personal or financial reasons. If the individual presenting for treatment had to be identified by facial recognition, their identity would be authenticated or denied. This could prevent someone from trying to use your insurance benefits or obtain access to your demographic or financial information. Again, this protects the security of confidential patient data. Facial recognition is also an important authentication feature in the healthcare field to establish the identity of patients, particularly those that are unresponsive. Early identification of these patients in emergency situations within an integrated EHR can give healthcare providers instant health information about medical conditions, medications, and allergies. Facial recognition provides a better alternative for identification than fingerprinting for burn victims those patients who have experienced amputations. Some genetic conditions allow diagnosis via facial recognition according to a study at the National Human Genome Research Institute. One provider of facial recognition software, Nextgate, â€Å"claims to simplify registration, flag fraudulent activity, and eliminate the creation of duplicate records† (McCleary, 2016). We may be able to eliminate duplicate records if this software meets its expectation. Duplicate records are a data quality issue that result in compromised â€Å"patient safety, medical care, data accuracy, and reimbursement† (Harris and Houser, 2018). Duplicate records occur for a variety of reasons, primarily human error due to transposing of letters and/or numbers during data entry, the use or non-use of middle names, and abbreviations. As we see more and more organizations merge or become part of a larger healthcare organization, the opportunity for duplicate medical records increase. â€Å"Duplicate records have caused negative outcomes in the discovery phase of the litigation process because there will be discrepancies with diagnoses, medications, and allergies† (Harris and Houser, 2018). Maintaining a single, confidential patient record ensures the availability and integrity of the patient data. Organizations are beginning to turn to biometrics to eliminate their duplicate records. The three possible methods include iris, palm vein, and fingerprint scanning. Iris scanning is the preferred method because it â€Å"supports hospital infection control initiatives and is very effective in preventing duplicates as there is a low occurrence of false positives and extremely low (almost zero percent) false negative rate† (Harris and Houser, 2018). With iris scanning, the technology never has to touch the patient whereas, palm vein and fingerprint scanning technology requires a physical contact between the patient and the technology. This increases the opportunity for infections to be spread. Organizations with an advanced enterprise master patient index (EMPI) are those that often contain patient information for multiple locations within one health system. The EMPI integrates data from the various systems forming an â€Å"overarching technology umbrella, resolving and synchronizing data issues and providing a single patient view that can be accessed across the enterprise. The EMPI resolves data quality issues and synchronizes back to enable accurate patient identification and matching that minimizes duplicates records† (Harris and Houser, 2018). The EMPI provides a level of confidentiality and security throughout the organization. When biometrics are implemented at the registration process and integrated into the EHR, health information professionals and providers can view and authenticate the patient information while working with the patient and within the EHR. Members of a data integrity team can verify patient records are properly integrating into the EHR as the patient moves through the health system. In areas where a facial recognition or fingerprint cannot be captured but a barcode can be scanned, the integration provides the patient's image for a comparison prior to medication administration or other service. This form of authentication provides an added security and safety feature. While all of this technology sounds like a win for the patient and the healthcare system in general, we must also consider the law. According to Hedges, three states (Illinois, Texas, and Washington) now have legislation that regulate how biometric information is collected and used. More states are expected to follow suit. The Illinois Biometric Privacy Act (BIPA), â€Å"defines biometric information to mean â€Å"any information, regardless of how it is captured, converted, stored, or shared, based on an individual's biometric identifier used to identify an individual.† (Hughes, 2018). BIPA does not include information captured in a healthcare setting or collected for treatment, payment, or healthcare options under HIPAA. It is uncertain how the Department of Health and Human Services will address biometric information at this time. One area that healthcare organizations should start to consider is how their business associates may interact with any biometric information they collect. The changing pace of technology is trying to keep up with the pace of today's security challenges. It seems as if each day we hear of another security breach or security issue almost daily. There are tools for the health information professional to address or combat areas information security issues. Two of the most powerful tools are iris scanning and facial recognition. These tools can authenticate employee and patient identification. By authenticating the employee, you maintain confidentiality of information. By authenticating the patient, you maintain patient safety and the integrity of your data.
