The Extraction Of Factors And Factors - 941 Words

The extraction of factors helps to determine the loading of factors. The factor loading matrix is shown below and is estimated with two common factors. The first column of the matrix depicts the first unrotated factor and it can be analysed that the first factor puts maximum and approximately equal weights to the first, second and fifth variable. And, it puts the minimum weight to the third variable, electricity. On the other hand, the second unrotated factor places the least weights to the first and second variable, while putting the highest weight to the third variable. Factor Loadings = Scatter plot of Unrotated Factor Scores The Figure. 15 shows the scatter plot of Score2 vs. Score1. It is clear that the 15th observation has the†¦show more content†¦Selecting an appropriate rotation is difficult task. Hence, it is preferable to perform both rotations on the factors. Varimax rotation technique results in high loading of each variable on a few number of factors, ideally on one factor and hence resulting in better factor analysis. The Figure. 18 shows the biplot of loadings of varimax rotated factors. It can be seen that in order to bring the loadings close to zero or one, varimax has rotated the axes. The four variables are close to first factor axis. While, the third variable lies approximately on second factor axis. Hence, the results of varimax rotation are satisfactory because most of the variables are near to the factor axis. Figure. 17 Promax rotation can be used incase we are not able to obtain the satisfactory and simple set of factors with an orthogonal rotation. The promax rotation allows the factor axes to have an oblique angle between them. The Figure. 19 shown belows depicts the promax rotation. It can be seen that the variables 1, 2 and 5 are close to the first factor axes and third variable is close to the second factor axis. The data is better accomodated in an oblique rotation. The two latent factors can describe variability of buildings and agriculture, which are having high impact on greenhouse gas emissions.

Veterans and PTSD Toni L. Enemy Hunter Psychiatric Rehabilitation/REHA 425 Professor McDermott October 29, 2011 Abstract The United States is seeing an increasing number of Veterans coming back from Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) being diagnosed with Post-Traumatic Stress Disorder (PTSD). We will write a custom essay sample on Veterans and Ptsd or any similar topic only for you Order Now PTSD is affecting the lives of men and women, their family and those closest to them. The goal of this paper is to give some general information for women and their families experiencing PTSD. It will give symptoms and treatment options available to women veterans. Women Vets and PTSD According to the 2009 and 2010 National Survey on Drug Use and Health, Substance Abuse and Mental Health Services Administration (SAMHSA), nearly 600,000 veterans aged 18 or older experienced a co-occurring substance use disorder and mental illness in the past 12 months. Post-Traumatic Stress Disorder (PTSD) is now becoming more prevalent with men and women in the military. How can the families of the veteran better understand what to expect and how to deal with their loved ones suffering from PTSD? Definition According to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR; APA, 2000) the diagnostic criteria for PTSD include a history of exposure to a traumatic event meeting two criteria and symptoms from each of three symptom clusters: intrusive recollections, avoidant/numbing symptoms, and hyper-arousal symptoms (Appendix 2). Challenges The British Medical Journal reported that veterans do not experience trauma or disabling symptoms until they return from the war (Gabriel Neal, 2002). Friedman said PTSD symptoms appear when they return home trying to readjust to civilian life. When a person is on active duty in the military, if one does not have a physical injury then psychological symptoms are seen as a weakness and being a coward (Friedman, 2004). Those that did seek help found it difficult to be diagnosed because they were not exposed to direct combat (i. e. hostile fire, returning fire, or seeing others injured). The veterans that do have PTSD from military trauma are from non-combative events such as sexual trauma. They may feel alone and worry about their families. PTDS is comorbid with traumatic brain injuries and other psychiatric disorders such as depression, social phobia, panic disorder, substance abuse, and mood and anxiety disorders (Feczer, 2009). [W]e deny that war changes its participants forever- †¦America claims innocence and goodness as fundamental traits. We believe that our young men and women should be able to go to war, get the job done, and return home blameless and well. (Tick, 2005) Intervention The Readjustment Counseling Service is available for veterans who served in war zones, Vietnam Era Veterans, veterans that experienced sexual trauma while in the military, and for family members that have lost loved ones while on duty. At a Veteran Center, the services that are provided are: individual counseling, group counseling, marital and family counseling, addiction counseling, benefits assistance and referral, employment referral and counseling, community education, liaison with VA facilities, referral to community agencies, contracts with area counselors and Mobile Vet Center Outreach. The client first has to go through assessments to figure out the best therapeutic approach. They need to be screened for victimization, suicidal potential, addictive behaviors, differential diagnosis, comorbidity, and family assessment (Meichenbaum, 1995). Medications, along with therapy, have been the most helpful types of treatment for PTSD. The medications used are antidepressant medications, anti-anxiety medications, mood stabilizing medications, and other medications to ease nightmares, irritability, sleeplessness, depression, and anxiety (Feczer, 2009). It is important when interviewing the client to find out their childhood history. Many times trauma during childhood will not come out until later in life and it can be the underlying issue to their problems (Feczer, 2009). Therapy Modalities PET After a traumatic event, many individuals experience distress and signs of PTSD. The veteran may experience suffering when dealing with the recollections related to the trauma. This type of therapy helps by approaching those thoughts, feelings, and events that the client has been avoiding because of the stress they cause. By repeated exposure to the emotions it helps the veteran reduce the power thoughts have over the client. However, during the assessment, it is important to discuss with the veteran the main event(s) that causes the stress. By doing this at a comfortable pace, the exposure to that trauma can be dealt with accordingly (Creamer amp; Forbes, 2004). The first part of the therapy is education. The counselor will explain the treatment, the common trauma reactions and symptoms of PTSD. PET helps the veteran understand what the goals are for the treatment and what to expect for the duration of the upcoming sessions. Teaching methods of breathing techniques will help the veteran to relax. Breathing changes when a person becomes anxious or fearful. This is a short-term technique to assist in managing sudden distress. The third aspect of PET is in vivo exposure where the client has exposure to real world situations or events that may be anxiety-producing. This is safely done by approaching the situation that has been avoided because of the stress it causes. PET uses imaginal exposure where the veteran talks through the trauma(s) with the counselor. By talking, it helps the client to gain control over the traumatic events and realize that he or she does not have to be afraid of his or her memories. The overall goal is to work through the events from least to most traumatic events and what is comfortable for the client. This type of therapy is usually eight to fifteen sessions that last about ninety minutes (Resick, Nishith, Weaver, Astin,amp; Feuer, 2002). CPT Many times those with PTSD have problems dealing with their thoughts and memories of the trauma they have been though. They may get â€Å"stuck† in their thoughts and have a hard time making sense of what has happened or is happening to them. CPT helps in giving clients a new way of dealing with their thoughts and to gain an understanding of the events that haunt them. There are four parts to CPT: learning about PTSD symptoms, becoming aware of thoughts and feelings, learning skills and understanding changes in beliefs. CPT requires educating the client about PTSD and what to expect from the disorder. The veterans can ask questions and find out how the skills are going to help them. In this modality, the client needs to become aware of their thoughts and feelings. When bad things happen we want to know why they happen. Clients can get stuck in their thought process and not be able to let it go. However, with CPT a person learns to pay attention to these thoughts that the trauma has caused and discuss how they make one feel. Then he or she can take a step back and see how it affects the person now. This will hopefully help the veteran think of the trauma in a different way. This can be done by writing about it or talking to the counselor. Next, the veterans need to begin learning the skills to help challenge their thoughts and question them as well. This is done by doing worksheets (appendix 1). These worksheets will help veterans decide the way they want to think and feel about their traumatic situations. These skills will eventually help in dealing with every day issues. Finally, there is trying to understand the changes in beliefs. There are common changes that happen after going through a trauma. There are going to be changes in the way a person thinks about safety, trust, control, self-esteem, other people and relationships. By talking about these beliefs, hopefully they can find a balance with the beliefs before and after the trauma. The approximate time for this type of therapy is twelve sessions. EMDR The final type of therapy is Eye Movement Desensitization and Reprocessing or EMDR. Clients that are involved in EMDR use imaginal exposure of their trauma and at the same time the counselor uses their index finger for them to follow back and forth. EMDR therapy seems to directly affect the brain by unlocking the traumatic memories, allowing clients to resolve them. Veterans work through the upsetting memory, beliefs, feelings, sensations until they are able to think about the event without reliving it. The memory is still there, but not as upsetting. It is like detaching oneself and watching a movie but relieving the trauma at the same time (Barton, Smith, Corcoran, 2011). Case Management, Employment and Vocational Rehabilitation According to the Vocational Rehabilitation and Employment Program that Congress prepared, case managers work closely with Vocational Rehabilitation Counselors (VRC) to create a rehabilitation plan. This plan consists of evaluation and planning for the future goals of the veteran. The veteran is evaluated to see if he or she is capable of independent living or will need rehabilitation services. The VRC is responsible to see that referrals for medical, eye care and dental are taken care of for the client. The vocational-education counselor will be able to assist the veteran in acquiring education, training, equipment, and financial aid if the client needs to develop new skills for employment. The President of the United States is also giving great tax breaks to employees for hiring veterans. The Counselor and Support Systems The downfall to helping veterans with PTSD is that there are not many counselors have the experience with this type of client. Counselors in this field are few, especially in the rural and underserved geographic areas. The VA resources are overwhelmed with clients so there is a backlog, which creates frustration with veterans. There are many that have contemplated or have committed suicide because they did not receive the help they needed. According to the National Center for PTSD, some may have had past mental health issues and may not have good support systems in addition to what was mentioned earlier. So that is why it is important to have a good support system and education is essential for the families when the veteran returns home. They will more than likely not be the same person as they were before they were deployed. Conclusion Veterans do so much for the United States citizens and we need to be thankful for the job they do for our freedom. The veterans put their lives in danger so we can live the life as Americans. Veterans deserve the respect and assistance when they return home to us. So it is my opinion that we do our best to ensure they can become productive citizens once again. I would like to be part of that team to assist in helping veterans adjust back into civilian life. I would like to see more citizens do the same by helping the veterans any way possible. Where would the United States be if we did not have such a great military team?

The diagnostic criteria (A-F) are specified below. Diagnostic criteria for PTSD include a history of exposure to a traumatic event meeting two criteria and symptoms from each of three symptom clusters: intrusive recollections, avoidant/numbing symptoms, and hyper-arousal symptoms. A fifth criterion concerns duration of symptoms and a sixth assesses functioning. Criterion A: stressor The person has been exposed to a traumatic event in which both of the following have been present: 1. The person has experienced, witnessed, or been confronted with an event or events that involve actual or threatened death or serious injury, or a threat to the physical integrity of oneself or others. . The person’s response involved intense fear, helplessness, or horror. Note: in children, it may be expressed instead by disorganized or agitated behavior. Criterion B: intrusive recollection The traumatic event is persistently re-experienced in at least one of the following ways: 1. Recurrent and intrusive distressing recollections of the event, inc luding images, thoughts, or perceptions. Note: in young children, repetitive play may occur in which themes or aspects of the trauma are expressed. 2. Recurrent distressing dreams of the event. Note: in children, there may be frightening dreams without recognizable content 3. Acting or feeling as if the traumatic event were recurring (includes a sense of reliving the experience, illusions, hallucinations, and dissociative flashback episodes, including those that occur upon awakening or when intoxicated). Note: in children, trauma-specific reenactment may occur. 4. Intense psychological distress at exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event. 5. Physiologic reactivity upon exposure to internal or external cues that symbolize or resemble an aspect of the traumatic event Criterion C: avoidant/numbing Persistent avoidance of stimuli associated with the trauma and numbing of general responsiveness (not present before the trauma), as indicated by at least three of the following: 1. Efforts to avoid thoughts, feelings, or conversations associated with the trauma 2. Efforts to avoid activities, places, or people that arouse recollections of the trauma 3. Inability to recall an important aspect of the trauma 4. Markedly diminished interest or participation in significant activities 5. Feeling of detachment or estrangement from others 6. Restricted range of affect (e. g. , unable to have loving feelings) 7. Sense of foreshortened future (e. g. , does not expect to have a career, marriage, children, or a normal life span) Criterion D: hyper-arousal Persistent symptoms of increasing arousal (not present before the trauma), indicated by at least two of the following: 1. Difficulty falling or staying asleep 2. Irritability or outbursts of anger 3. Difficulty concentrating 4. Hyper-vigilance 5. Exaggerated startle response Criterion E: duration Duration of the disturbance (symptoms in B, C, and D) is more than one month. Criterion F: functional significance The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. Specify if: Acute: if duration of symptoms is less than three months Chronic: if duration of symptoms is three months or more Specify if: With or without delay onset: Onset of symptoms at least six months after the stressor (American Psychiatric Association, 2000) How to cite Veterans and Ptsd, Papers

Analysis of Death of a Salesman opening stage directions free essay sample

Arthur Miller’s ‘Death of a Salesman’ (1949) opens with an extensive description of the Loman house. Miller uses extremely precise and detailed stage directions, including prop placement, sound and lighting, giving heavy significance to each of these elements and painting an unchangeable picture to ensure that it is preserved in every interpretation of his work. Throughout the opening stage directions of Act 1, despite the structure and tone being very factual, composed of short, clear sentences, Miller hints at underlying themes and messages through a range of stylistic devices, preparing the audience for the play, and setting the scene. As the play is set in Brooklyn, New York some years after the great depression, many references are made already at this early stage to idealism and the American dream; the desperate and yearning vision of many Americans at that time of a better life. This permeating theme becomes apparent formerly even to the introduction of the characters, as the mere scenery and props act as symbolic elements, which reflect this motif. We will write a custom essay sample on Analysis of Death of a Salesman opening stage directions or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Miller however subliminally makes it evident that this dream is purely an illusion, through emblematic phrases in his stage directions such as ‘rising out of reality’ and physical representations, for instance the broken boundaries where ‘characters enter or leave a room by stepping through a wall onto the forestage’ which create an aura of delusion. The first stage directions include a melody played on a flute, ‘telling of grass and trees and the horizon’. This natural imagery encompassing three physical elements accompanied by the soft and harmonious sound, sets a serene tone which is then highly juxtaposed with the following depiction of the house and it’s neighborhood, featured with darkness and hostility. This heavy contrast may be symbolic of the conflict between the dreams to which the individual aspires and the actual harshness of society’s reality. The description of the surrounding cluster of apartment blocks seems almost to have a greater prominence than the house itself, as this is the first thing the audience ‘becomes aware of’. The tall and ‘angular’ silhouette of Manhattan that lies in the backdrop has expressionistic features and surrounds the Loman house in a way that suggests some metaphorical form of oppression or confinement. The ‘glow of orange’ that falls upon the ‘fragile-seeming’ house is personified as ‘angry’, perhaps reflecting the hostile times in which the play is set. This enclosing and intimidating hostility is in part what makes the home appear so fragile, a fragility that may represent weakness in family bonds or equally, weakness in he who represents the house, condemning him immediately to the role of a tragic protagonist. Willy clings to his dreams just as ‘an air of the dream clings to the place’. This idea becomes present again in the description of Linda’s feelings towards her husband and his traits. ‘his massive dreams’ are the source of his tragic nature, dreams that he shares with the rest of society, but that for him become an unhealthy obsession. Willy is cursed with the incessant desire to pursue his dreams ‘to their end’ and these words forebode a fate that unfolds as a result of this fixation. Overall the opening of this play provides the audience with a sense of the themes that will permeate throughout, by cleverly using stage schemes and elements that insinuate profounder significance of what is to come. The audience is hereby prepared for the play and begins to form judgments and predictions shaped around this carefully strategized scenery.
