Reciprocal and Reflexive Sentences in Spanish

Proportional and Reflexive Sentences in Spanish Understanding or deciphering reflexive or equal sentences in Spanish where there are at least two subjects can be confounding in light of the fact that they can be questionable without qualifiers. Figure out how these sorts of sentences are developed and how to take out equivocalness in Spanish utilizing two normal expressions. Why There Can Be Ambiguity in Spanish Sentences To begin with, let us characterize and develop what aâ reflexive sentence is. The pronoun se is normally utilized (despite the fact that it has numerous different uses also) to demonstrate that an individual is playing out some kind of activity on or toward that individual. For instance, se ve can mean he sees himself and se hablaba can mean she was conversing with herself. The disarray with reflexive sentences can come when the subject of such sentences is plural. It couldn't be any more obvious, for instance, how the accompanying Spanish sentences are uncertain. Both of the interpretations given after the Spanish sentence is substantial: Se ayudaron. (They helped themselves. They helped each other.)Se golpean. (They are hitting themselves. They are hitting each other.)Pablo y Molly se aman. (Pablo and Molly love themselves. Pablo and Molly love one another.) A similar vagueness can exist in the first and second people also: Nos daã ±amos. (We hurt ourselves. We hurt each other.)Nos amamos. (We love ourselves. We love each other.) ¿Os odiis? (Do you loathe yourselves? Do you detest one another?) The issue happens on the grounds that in Spanish the plural corresponding pronouns are equivalent to the reflexive pronouns; they are nos in the main individual, os in the subsequent individual, and se as an outsider looking in. (Note that in Latin America os is only occasionally utilized, as se is regularly utilized in both the second-and third-individual plurals.) This is conversely with English where the reflexive pronouns in the plural are ourselves, yourselves, and themselves-however the complementary pronouns are one another and each other. Step by step instructions to Clarify When Context Doesn’t Help More often than not, the setting of the sentence will clarify what significance is expected. On the off chance that the setting doesn't help, there are two extremely regular expressions that can be utilized to wipe out the vagueness. Initially, the maxim a sã ­ mismos is normally used to demonstrate that a reflexive significance is expected as such, that the subjects are following up on themselves as opposed to one another. For instance: Se aman a sã ­ mismos. (They love themselves.)No pueden refrain a sã ­ mismos. (They cannot see themselves.)Es importante que nos escuchemos a sã ­ mismos. (It is significant that we hear ourselves out.) In the event that all the people included are female, or if the names of all subjects are syntactically ladylike, the female structure a sã ­ mismas ought to be utilized: Cã ³mo se perciben a sã ­ mismas las mujeres con la infertilidad? (How do ladies with fruitlessness see themselves?)Cuà ­dense a sã ­ mismas. (Deal with yourselves.)Estas piernas robã ³ticas child capaces de enseã ±arse a sã ­ mismas an andar. (These mechanical legs are equipped for instructing themselves to walk.) Second, the expression el uno al otro, which can be actually made an interpretation of as one to the next, is what could be compared to one another: No debemos hacernos eso el uno al otro. (We shouldnt do that to each other._Se golpean el uno al otro. (They are hitting each other.)El ordenador y el screen se necesitan el uno al otro. )The PC and the screen need each other.) ¿Os odiis el uno al otro? (Do both of you loathe one another?) El uno al otro can likewise be utilized in ladylike as well as plural varieties: Pablo y Molly se aman el uno a la otra. (Pablo and Molly love each other.)Se abrazaban la una a la otra. (The two females embraced each other._No se cuidan los unos a los otros. (They (various people) dont deal with one another.) Key Takeaways Reflexive pronouns are utilized to demonstrate that at least two people or things are following up on themselves, while corresponding pronouns are utilized to show that at least two people or things are following up on themselves.Although English has separate reflexive and proportional pronouns, in Spanish they are identical.Spanish can utilize the expressions a sã ­ mismos (or a sã ­ mismas) and el uno al otro (with varieties for number and sexual orientation) to explain reflexive and equal action words, individually.

Hearing Voices in Schizophrenia

Hearing Voices in Schizophrenia Schizophrenia Print Hearing Voices, or Auditory Hallucinations, in Schizophrenia By Adrian Preda, MD Medically reviewed by Medically reviewed by Steven Gans, MD on June 28, 2016 Steven Gans, MD is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital. Learn about our Medical Review Board Steven Gans, MD Updated on January 31, 2020 Schizophrenia Overview Symptoms & Diagnosis Causes & Risk Factors Treatment Living With In Children Westend61 / Getty Images Auditory hallucinations, or hearing voices, is a common symptom in people living with schizophrenia. In fact, an estimated 70 to 80% of people with schizophrenia hear voices.?? These voices can call your name, argue with you, threaten you, come from inside your head or via outside sources, and can begin suddenly and grow stronger over time. People living with other mental illnesses, including bipolar disorder, borderline personality disorder, major depressive disorder, post-traumatic stress disorder, and schizoaffective disorder, also experience hearing voices. Auditory perceptual illusions are not as uncommon as we once thought. In fact, up to 10% of the general population have had the experience of hearing one’s name called,?? especially during the twilight times of falling asleep (hypnopompic) or waking up (hypnagogic). Types of Auditory Hallucinations For some, auditory hallucinations appear suddenly. T. M. Luhrman, a professor of anthropology at Stanford and author of Living With Voices, described the experience of a young man who started hearing the sound of rats scratching behind his ears.?? His auditory hallucinations began rapidly and soon after he destroyed a number of rats nests. Another young man started to suddenly hear a voice coming from outside his apartment that sounded like a woman screaming; she was raped and begging for help. Many times the voices can start gradually and are often described as a vague or fleeting impression of hearing your name called or people talking about you. For example, Someone just called my name” or “people were talking in the hallway,” or “I thought I heard something but then I am not sure.” People with schizophrenia can hear a variety of noises and voices, which often get louder, meaner, and more persuasive over time. A few examples of the type sounds that might be heard: Repetitive, screeching sounds suggestive of ratsPainfully loud, thumping music themesVoices of people blasting mean orders or commentsPeople talking about you as if you were not even present How Do You Know If Youre Having Hallucinations? Nonsensical Voices As Eleanor Longden, a research psychologist with a diagnosis of schizophrenia explains, the voices can order you to do completely nonsensical things, such as taking a glass of water and pouring it over your head.?? Due to their repetitive, incessant, annoying quality, the voices can make people profoundly distracted and overwhelmed to the point of choosing to follow their orders. Self-harm Voices Voices giving orders to harm oneself or others need to be approached with great caution. This type of auditory hallucination can be extremely frightening as the orders tend to be screamed non-stop. Threatening Voices Some people hear persuasive, repetitive voices by a secret organization, for example, that threaten death or harm. Again, these voices are frightening and increase a persons risk of self-harm or violence. Treatment Treatment for schizophrenic voices typically requires a combination of medications, therapy, and other procedures for those who are treatment-resisted. Antipsychotics: These medications are often the first line of treatment and have been study-proven to rapidly decrease the severity of auditory hallucinations.Cognitive-behavioral therapy (CBT): When used in combination with medication, CBT can help reduce the emotional distress of schizophrenic voices and help people develop skills to cope with and quiet the voices. For example, humming the Happy Birthday song or reading a paragraph backward when the voices begin.Repetitive transcranial magnetic stimulation (rTMS): Also known as Repetitive TMS, this relatively non-invasive procedure involves placing a small magnetic device directly on the skull. It has been shown to reduce the frequency and severity of auditory hallucinations in people with schizophrenia.Electroconvulsive therapy (ECT): Considered a last-resort treatment for reducing the severity of auditory hallucinations, ECT involves the application of a brief electrical pulse to the scalp in order to produce a seizure.?? Find Help With the 9 Best Online Therapy Programs For Caregivers and Loved Ones Coping with a loved one who is struggling with schizophrenic voices can take a tollâ€"but try not to lose hope. With the right treatment, your loved one may be able to control the frequency and severity of these voices. You also may consider family therapy, which can help you and your loved one recognize these auditory hallucinations and develop strategies to better cope.

Follow the Rabbit Proof Fence Free Essays

‘This free-spirited girl knew that she and her sisters must escape from this place’. What characteristics did Molly display which enabled the sisters to escape and return to their families? Not only is this book about how three little aboriginal girls travelled across half of Australia but is also teaches us how the aboriginals were treated. Throughout Doris Pilkington’s and Nugi Garimara’s novel, the protagonist Molly, has a set of characteristics that help her and her two cousins escape from the re-education camp for half-casts, she is strong mentally when she was bullied, she is knowledgeable because she was able to cross half of Australia with no map or compass, and she is very loyal and emotionally attached to her land. We will write a custom essay sample on Follow the Rabbit Proof Fence or any similar topic only for you Order Now When Molly was only about four years, she was constantly bullied because she was a half-cast, but besides these constant insults, she was strong and kept positive. Because she was neither a Mardu nor wudgebulla and was regarded as a mongrel dog and wasn’t liked by the aboriginal children so she threw â€Å"handfuls of sand or stones and threw them at her tormentors, and sometimes she chased them with a stick. † But as she got older she â€Å"became used to the insults, and although they still hurt, she didn’t show it. † This shows Molly’s mental strength against her bullies and tried to stay positive even though she â€Å"Wished that she didn’t have light skin so that she didn’t have to play by herself. She is also mentally strong because for three young girls to travel from Perth to Jigalong, she needs to be in the right mindset and be positive because she was determined to get back because she needed to see her family. Not many people could and would be able to do this but these girls especially Molly were brave and persistent and kept their head up. So it can be said that Molly is mentally st rong because she is able to beat her bullies and go back home to Jigalong. When Molly and her two cousins escape the camp, she is faced with an enormous walk without a compass or map, but Molly has grown up in this land and knows what to do and where to go. She â€Å"had no fear because the wilderness was her kin. † This means that the wilderness is her family which â€Å"always provided shelter, food and sustenance. † She also memorised which was they travelled so she knew to head north and to follow the rabbit-proof fence. With her developed bushcraft skills and survival techniques she was able to lead her two cousins through traitorous terrain and back home and also lead the tracker and constable Rigs to the wrong places. Therefore it can be said that throughout the novel, Molly uses her knowledge of the land to get back home safely with her cousins and remove their tracks. Throughout the novel, we see that Molly is very loyal and emotionally attached to her land. We see this when Molly and Gracie were walking through the country when they were almost home and they are pointing out special places to each other, for Molly it was a â€Å"Quick trip down memory’s landscape† which â€Å"A feeling of nostalgia brought tears to her eyes. † This shows how much she missed and appreciates the land she grew up in and shows us how loyal she is to it. It means so much to her and like in the movie ‘Kanyini’ without it she is nothing. So it can be said that Molly is loyal and emotionally attached to her land especially when it gets taken away from her. Throughout the novel written by Doris Pilkington and Nugi Garimara, Molly has a set of traits which help her and her cousins escape the re-education camp, travel a substantial distance and get back to Jigalong safely. It was her inner strength, her knowledge of her land and her emotional attachment to her land. We can also learn from this book that someone cannot take from others even if they think it is the right decision. Doris Pilkington and Nugi Garimara tell us just one of many stories that has happened to many of the stolen generation and it makes us think about it.

Adolesent Depression Essay Example For Students

Adolesent Depression Essay Depression is a disease that afflicts the human psyche in such a way that the afflicted tends to act and react abnormally toward others and themselves. Therefore it comes to no surprise to discover that adolescent depression is strongly linked to teen suicide. Adolescent suicide is now responsible for more deaths in youths aged 15 to19 than cancer (Blackman, 1995). Despite this increased suicide rate, depression in this age group is greatly underdiagnosed and leads to serious difficulties in school, work, and personal adjustment which may often continue into adulthood. How prevalent are mood disorders in children and when an adolescent with changes in mood be considered clinically depressed? Brown has said the reason why depression is often over looked in children and adolescents is because children are not always able to express how they feel. Sometimes the symptoms of mood disorders take on different forms in children than in adults. Adolescence is a time of emotional turmoil, mood swings, gloomy thoughts, and heightened sensitivity. It is a time of rebellion and experimentation. Blackman observed that the challenge is to identify depressive symptomatology which may be superimposed on the backdrop of a more transient, but expected, development storm. Therefore, diagnosis should not lay only in the physicians hands but be associated with parents, teachers and anyone who interacts with the patient on a daily basis. Unlike adult depression, symptoms of youth depression are often masked. In stead of expressing sadness, teenagers may express boredom and irritability, or may choose to engage in risky behaviors (Oster Montgomery, 1996). Mood disorders are often accompanied by other psychological problems such as anxiety (Oster Montgomery, 1996), eating disorders (Lasko, 1996), hyperactivity (Blackman, 1995), substance abuse (Blackman, 1995; Brown, 1996; Lasko, 1996) and suicide (Blackman, 1995; Brown, 1996; Lasko, 1196; Oster Montgomery, 1996) all of which can hi de depressive symptoms. The signs of clinical depression include marked changes in mood and associated behaviors that range from sadness, withdraw, and decreased energy to intense feelings of hopelessness and suicidal thoughts. Depression is often described as an exaggeration of the duration and intensity of normal mood changes (Brown, 1996. Key indicators of adolescent depression include a drastic change in eating and sleeping patterns, significant loss of interest in previous activity interests (Blackman, 1995; Oster Montgomery, 1996), constant boredom (Blackman, 1995), disruptive behavior, peer problems, increased irritability and aggression (Brown, 1996). Blackman proposed that formal psychological testing may be helpful in complicated presentations that do not lend themselves easily to diagnose. For many teens, symptoms of depression are directly related to low self-esteem stemming from in creased emphasis on peer popularity. For other teens, depression arises from poor family relations which could include decreased family support and perceived rejection by parents (Lasko, 1996). Oster Montgomery stated that when parents are struggling over marital or career problems, or are ill themselves, teens may feel the tension and try to distract their parents. This distraction could include increased disruptive behavior, self-inflicted isolation and even verbal threats of suicide. So how can the physician determine when a patient should be diagnosed as depressed or suicidal? Brown suggested the best way to diagnose is to screen out the vulnerable groups of children and for the risks factors of suicide and then refer them to treatment. Some of these risk factors include verbal signs of suicide within the last three months, prior attempts at suicide, indication of sever mood problems, or excessive alcohol and substance abuse. Many physicians tend to think of depression as an illness of adult hood. In fact, Brown, stated that it was only in the 1980s that mood diso rders in children were included in the category of diagnosed psychiatric illnessess. In actuality, 7-14% of children will experience an episode of major depression before the age of 15. An average of 20-30% of adult bipolar patients report having their first episode before the age of 20. In a sampling 100,000 adolescents, two to three thousand will have mood disorders out of which 8-10 will commit suicide ( Brown,1996), (Blackman, 1995) remarked that the suicide rate for adolescents has increased more than 200% over the last decade. Brown added that an estimated 2,000teenagers per year commit suicide in the United States. Making it the leading cause of death after accidents and homicide. Blackman stated that it is not uncommon for young people to be preoccupied with issuses of mortality and to contemplate the effect their death would have on close family and friends. Once it has been determined that the adolescent has the disease of depression, what can be done about it? Blackman ha s suggested two main avenues to treatment: psychotherapy and medication. The majority of cases of adolescent depression are mild and can be dealt with through several psychotherapy sessions of intense listening, advice and encouragement. Comorbidity is not unusual in teenagers, and possible pathology, including anxiety, obsessive-compulsive disorder, learning disability or attention deficit hyperactive disorder, should be searches for and treated, if present (Blackman, 1995). For the more severe cases of depression, especially those with constant symptoms, medication may be necessary and without pharmaceutical treatment, depressive conditions could escalate and be fatal. Brown added that regardless of the type treatment chosen, it is important for children suffering from mood disorders to receive prompt treatment because early onset places children at a greater risk for multiple episodes of depression throughout their life span. Until recently, adolescent depression has been largely ignored by health professionals, but now several means of diagnosis and treatment exist. Although most teenagers can successfully climb the mountain of emotional and psychological obstacles that lie in their paths, there are some who find themselves overwhelmed and full of stress. How can parents and friends help out these troubled teens? And what can these teens do about their constant and intense sad moods? With the help of teachers, school counselors, mental health professionals, parents, and other caring adults, the severity of a teens depression can not only be accurately evaluated, but plans can be made to improve his or her well-being and ability to fully engage life. .uea3061961c9ec6d235584f886b31ba95 , .uea3061961c9ec6d235584f886b31ba95 .postImageUrl , .uea3061961c9ec6d235584f886b31ba95 .centered-text-area { min-height: 80px; position: relative; } .uea3061961c9ec6d235584f886b31ba95 , .uea3061961c9ec6d235584f886b31ba95:hover , .uea3061961c9ec6d235584f886b31ba95:visited , .uea3061961c9ec6d235584f886b31ba95:active { border:0!important; } .uea3061961c9ec6d235584f886b31ba95 .clearfix:after { content: ""; display: table; clear: both; } .uea3061961c9ec6d235584f886b31ba95 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uea3061961c9ec6d235584f886b31ba95:active , .uea3061961c9ec6d235584f886b31ba95:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uea3061961c9ec6d235584f886b31ba95 .centered-text-area { width: 100%; position: relative ; } .uea3061961c9ec6d235584f886b31ba95 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uea3061961c9ec6d235584f886b31ba95 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uea3061961c9ec6d235584f886b31ba95 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uea3061961c9ec6d235584f886b31ba95:hover .ctaButton { background-color: #34495E!important; } .uea3061961c9ec6d235584f886b31ba95 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uea3061961c9ec6d235584f886b31ba95 .uea3061961c9ec6d235584f886b31ba95-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uea3061961c9ec6d235584f886b31ba95:after { content: ""; display: block; clear: both; } READ: Why the Homeless Must Vote Essay

In collaboration with the other departments, its prime purpose is to provide facilities for the engineering undergraduates to perform the academic activities of the Faculty of Engineering. During the time of training, it comprised a resource crew of fifty one members directed by Dr. S. D. Pathirana, a senior lecturer of the Department of Production Engineering. 1. 1 SERVICES AND MAJOR FUNCTIONS The infrastructure of the Engineering Workshops could provide the following listed services to its consumers both in academic and non-academic terms. Machining of metals Welding Foundry work Smith and fitting work Woodwork Vehicle repair Subject to the rules established by the Faculty and the University, deploying the following functions was expected from it. Provide above mentioned services to the engineering undergraduates to carry out their academic activities such as practicals, experiments and etc. Provide above mentioned services to the Faculty of Engineering and the University as a whole if requested. Within the feasibility limits, provide above mentioned services to the public. (Service cost is usually expected to be charged from the service consumers). It is important to distinctly note that the Engineering Workshops could provide related knowledge wise services to other engineering organizations and to the public who need assistance in their work. . 2 DIFFERENT SECTIONS AND CLOSE RELATIONSHIPS The Engineering Workshops itself is a collection of five different subsections that are interrelated. Brief descriptions about them are given below. 5 1. 2. 1 DIFFERENT SECTIONS 1. 2. 1. 1 Metal Workshop The Metal Workshop is the place for machining metals.

A simple example is using stainless steel for a product that should not get stained. Furthermore the effective processing of these materials until a finished product is obtained requires the knowledge of processing characteristics of the materials. For example consider machining stainless steel. Some important points to be considered are: The tool material that should be used. The level of machining (i. e. rough or finish) The cutting speed Requirement of coolants Table 2-1 gives the cutting speeds of the commonly used materials under different conditions. 10 Table 2-1 Cutting Speeds Workpiece Material Rough cut (ft/min) Finish cut (ft/min) Rough cut (ft/min) Finish cut (ft/min) Cast iron Mild Steel Malleable iron 80-110 110-130 250-300 300-400 Cast iron Bronze Aluminium Stainless steel 100-120 100-120 140-200 240-360 Brass HSS tools 50-60 80-110 120-200 350-400 40-50 65-90 140-160 250-300 45-60 70-90 150-180 200-250 110-150 150-180 600 1000 400 700 800 1000 200-300 200-300 600-1000 600-1000 Carbide tools 11 CHAPTER 3: MACHINE TOOLS AND SPECIFICATIONS 3. 1 PLANNING MACHINE Unlike most of other machines, the planning machine contains a sliding table which carries the workpiece. Cutting tools do not move but the workpiece. The one in Metal Workshop was not frequently used because of the heavy operating cost. It was only used for heavy duty metal works. The prime mover of the sliding table is a DC motor with the following specifications.

The detachable milling head is used when vertical milling is performed and can be turned vertically to mill at any other inclination. Specifications of the machine are listed below. Manufacturer Spindle motor Brown and Sharp MFG Company, USA 230 V, 3 phase, 50 Hz, 9 A (full load) Cutter Speeds Feed rates 33 to 1275 rpm 3/8 to 16 7/8 inch/min 3. 3 SHAPER A shaper contains a table on which the workpiece is mounted. The linear movement of the cutting tool wipes away the excess material. This is exactly the opposite of what happens in the planning machine where the tool is fixed and the workpiece is linearly moved. The Metal Workshop has two shapers, a fully mechanical one and a hydraulic operated one. The ram moving motor of the fully mechanical shaper is of 2HP and that of the hydraulic one is 7. 5HP. The mechanical shaper has a constant speed prime mover which turns a disk as shown in Figure 3-1 to convert the rotational movement of the prime mover into reciprocal motion of the cutting tool. TOO e Figure 3-1 Rotational Into Reciprocal Motion Conversion 14 This arrangement allows quick return motion. Further more this allows feed rate change without any gear arrangement or control of speed of motor. This is done by varying the eccentricity e. The higher the e, the higher the feed rate is. A simple trade off of this feed rate control system is that as the feed rate is reduced, the stroke of the ram also gets reduced. The hydraulic type shaper does not have this problem and the feed rate and the stroke can be independently controlled. Figure 3-2 shows the hydraulic arrangement. This machine has been manufactured by Rockford Machine Tool, Rockford, Illinois, USA.

The specifications of the NHP1030 hand drill manufactured by Makita Corporation, Japan are given below. Supply 230 VAC, 2. 0 A, 50-60 Hz 430 W 0-2700 rpm drill Power Speed Maximum bit size 10 mm 15 CHAPTER 4: CNC MACHINING CENTER 4. 1 HITACHI SEIKI VA35 CNC MACHINING CENTER The Hitachi Seiki VA35 CNC (Computer Numeric Controlled) machining center that belongs to the Department of Production Engineering is frequently used for accurate and automated machining of metals as well as for wood, plastic and other materials. The machining accuracy of the machine is 0. 001mm. Figure 4-2 shows various parts of the machine tool. Figure 4-1 Hitachi Seiki VA35 CNC Machining Center 16 Figure 4-2 Hitachi Seiki VA35 CNC Machining Center 17 Manufactured by Hitachi Seiki Co. Ltd. , Japan, the control unit of this numerically controlled milling machine is of Fanuc System 6M-B. The controlling is based on two Intel 8085 microprocessors.

G Codes define the preparatory functions of the machine. In simple terms, they control the movement and machining related functions of the machine tool. For example, the code G76 followed by some related arguments is used for fine boring. G00 with X,Y,Z arguments rapidly moves the bed and the spindle head to the position specified by the arguments. M Codes are known as auxiliary functions. They control specific behaviors of the machine. For example M08 turns on the coolant, M05 stops the spindle. 4. 4 AN EXAMPLE PROGRAM The listing given below is a program which was used to bore holes in couplings of two turbines which were manufactured in the Engineering Workshops. It is written in G and M Codes.

End of sub program. 2 3 4 4. 5 STEPS IN USING THE MACHINE The distinct operations involved in using the CNC machine are listed below in sequence they are done. 1. Generating the program (in G M Codes) 2. Sending it to the machine 3. Running the program First a drawing of the machined workpiece is created using AutoCAD in a PC. Then using a special routine of AutoCAD, the contours of the cutting tool are generated. This is finally stored as a text file in the hard drive of the PC. Next, the CNC machine is set to retrieve this file. Through the coaxial cable which links the PC and CNC machine, it is then fed into the machine tool. A numeric name for the program is given at the beginning of the file retrieval to figure out the starting point (or the address in the memory) of the retrieving program from earlier read programs. Using this numeric name of the program, it is taken to the front from other programs in the memory and it stays waiting to run. Pressing the Start button sequentially executes the listing. Figure 4-4 shows the monitor (on the Main Control Panel) displaying a program waiting to be executed. If needed a program can directly be written using the Main Control Panel of the CNC machine and executed. This is tedious and errors may occur easily. 22 Figure 4-4 A Program Waiting To Be Executed (Sub Control Panel Display) 23 CHAPTER 5: FEASIBILITY SURVEY ON A MINI-HYDRO POWER PROJECT 5. 1 INTRODUCTION This chapter described the methods that were used for flow rate prediction and measurement and head measurement of a stream called Madapiti Oya in Nuwara Eliya district as a feasibility survey to construct a mini-hydropower plant. APPENDIX A: FEASIBILITY REPORT ON THE PROPOSED MINI-HYDRO POWER PROJECT AT KABARAGALA ESTATE contains full details of it. The capacity of a hydropower scheme entirely depends on two factors being the water flow rate and the head (the height difference between the reservoir and the power house). 5. 2 FLOW PREDICTION AND MEASUREMENT Two methods that were carried around the stream are described here. One is a flow prediction method and the other one is a flow measurement method. 5. 2. 1 AREA-RAIN FALL METHOD This is a flow prediction method. In simple terms, the catchment area of a water stream is multiplied by the rainfall to find the flow. Figure 5-1 shows an example contour map that can be used in this method to find the catchment area of a stream. The lighter dashed lines enclose the areas. For example the area which determines the flow at point B of the stream is enclosed by the outer light dashed lines bounded by three mountain peaks. Figure 5-1 Using A Contour Map To Find The Catchment Of A Stream Figure 5-2 shows a simple representation of a hydrological cycle. It is seen that sub-surface transfer flow, evaporation and transpiration reduce some amount of water from the value 24 calculated just by multiplying the area and the rainfall. Depending on the weather and geographical conditions, suitable corrections for these can be applied for a more accurate flow prediction. Figure 5-2 The Hydrological Cycle 5. 2. 2 THE FLOAT METHOD This is a flow measurement method. As shown in Figure 5-3, the time taken for a float to travel a known distance on the surface of the stream is found and hence the mean velocity of the stream. The mean velocity depends on the bed surface of the stream and hence a correction factor is applied for the velocity given by the division of the float length by the time in calculating it. The mean cross sectional area of the steam is also found. The flow is obtained by multiplying the mean values of cross sectional area and velocity. Figure 5-3 Float Method Of Flow Measurement 25 5. 3 HEAD MEASUREMENT 5. 3. 1 PRESSURE GAUGE METHOD Being not a very accurate method, pressure gauge method of head measurement employees a calibrated pressure gauge into which a long transparent water filled open ended pipe is fitted. A B Figure 5-4 Pressure Gauge Method Of Height Measurement Figure 5-4 shows how a pressure gauge is used in height measurement. The calibrated pressure gauge at B directly reads the pressure at point B with reference to point A. This reading can then be used to calculate the height difference between points A and B using the density of water. The open end A of the pipe is then taken to point B and the meter can then be moved down to a point below the point B. This is done from the expected beginning to the expected end of the penstock and the head is calculated from the sum of reading of the meter. 5. 3. 2 TACHEOMETRIC SURVEYING This is an accurate method of head measurement which uses an optical theodolite as shown in Figure 5-5. Figure 5-5 Tacheometric Surveying A measuring staff is kept at point X and readings at points A, B and C which can be identified because of the cross hairs and stadia hairs of the instrument are taken. The inclination of the 26 ines of sight (? ) is also taken. These measurement can be mathematically manipulated to find the vertical and horizontal distances between the instrument and a given point. Thus a vertical profile along a path can be generated. If a compass is additionally used at the instrument position to find the direction of point X relative to some reference direction (magnetic nort h), a bird’s eye view of the surveyed path can also be drawn. 27 CHAPTER 6: MANUFACTURING CROSS FLOW TURBINES 6. 1 INTRODUCTION During the time of training, two similar 280kW cross flow turbines were manufactured in the Engineering Workshops. They were intended to be directly coupled to the generator as shown in Figure 6-1. WATER TURBINE COUPLING WATER GENERATOR Figure 6-1 Direct Coupled Turbine The following sections describe each component of the above system. 6. 2 A CROSS FLOW TURBINE Figure 6-2 shows the cross section of a cross flow turbine that had been manufactured earlier in the Engineering Workshops. 28 Figure 6-2 A Cross Flow Turbine In a cross flow turbine, the blades are arranged in a squirrel cage. Water from the penstock hits a blade and travels across the cage, hits a second blade and leaves out. This is illustrated in Figure 6-2. The turbine shown in Figure 6-2 has a governor connected to it internally. The latter produced ones do not contain governors. Figure 6-3 shows the external dimensions of a 280kW cross flow turbine that was manufactured in the Engineering Workshops. 29 520mm 590mm ? 80mm 540mm 840mm 770mm Figure 6-3 External Dimensions Of A 280kW Cross Flow Turbine The squirrel cage blade structure of the turbine is kept in position by two bearings at each end of the rotor. The especial feature is that one of them is of self aligned type. A self aligned bearing allows the axis of the shaft which goes through it not to be the same axis of the outer fixed frame and the inclination may vary. This is shown in Figure 6-4. INCLINED TRUE AXIS OF ROTATION NOMINAL AXIS OF ROTATION Figure 6-4 A Self Aligned Bearing The self aligned bearing allows the manufacturing eccentricity of the bearing mounts not to cause vibrations or related mechanical failures. 30 6. 3 COUPLINGS The connection between the turbine and the generator is established by a set of cast iron couplings shown in Figure 6-5. Each of these couplings contains fifteen nylon bushes. Each bush on the turbine side coupling is connected to one bush on the generator side coupling using a metal rod. The nylon bush arrangement reduces vibrations and related failures due to possible eccentricities that may exist between two shafts. one set of connectors METAL ROD NYLON BUSHES TURBINE SIDE GENERATOR SIDE Figure 6-5 Coupling Between Turbine And Generator 6. 4 GENERATOR The alternator for an above turbine is of brushless self excited type with an automatic voltage regulator fitted into it.

OUT Figure 6-6 Brushless, Automatic Voltage Regulated Alternator 31 CHAPTER 7: OTHER ACTIVITIES 7. 1 MANUFACTURING A CHALK MACHINE The chalk machine that was being manufactured in the Engineering Workshops used a piston-cylinder arrangement in producing crayons. Made of brass, Figure 7-1 shows one such piston-cylinder pair. MOLTEN PASTEL CYLINDER WATER PISTON Figure 7-1 A Piston Cylinder Pair Of The Chalk Machine The operation is as follows: 1. Fill the cylinders with molten pastel. 2. Pass water around the cylinders to solidify the crayons quickly. 3. Move the piston upwards to remove the crayons. The machine contained a set of piston-cylinder pairs which worked simultaneously. Pressing the molten pastel into the cylinders and moving the piston upwards were performed by using two hydraulic jacks one on top and the other under the piston-cylinder structure. 7. 2 SELF POWERED WATER PUMP FOR RIVERS This is a design of Professor Sanath Ranathunga and I had no personal involvement with it. A pipe is spiral wound inside a thrown away barrel as shown in Figure 7-2. The barrel is fitted with blades on its surface and submerged in the river. As the barrel rotates, water and air enter and pipe from its open end one after another. This pressurize the water inside the pipe and naturally elevates to a higher level. 32 AIR SPIRALED PIPE BARREL WATER BLADES Figure 7-2 The Self Powered Water Pump For Rivers 7. 3 MILLING A PRINTED CIRCUIT BOARD The conventional way of creating a printed circuit board or PCB for short involves chemical etching of unwanted portions of copper from a copper clad board. Instead of using a chemical, milling away the unwanted portions of the copper surface reduces time and effort needed in creating PCBs drastically. Though some drawbacks exist, this was tried on the small universal milling machine and satisfactory results could be obtained. First some broken tool shanks were found and ground to the shapes shown in Figure 7-3 using the drill bit grinder. a 0. 5mm b 0. 5mm Figure 7-3 Tools To Mill A PCB Figure 7-4 Milling A PCB Cutter (a) in Figure 7-3 created a rough surface finish. The shape of the cutting edge of cutter (b) was seen to force the copper chips into the board producing a smooth surface finish. 33 7. 4 AN ELECTRONIC ROTATION COUNTER On request of the Workshops Director Dr. S. D. Pathirana, an electronic rotation counter was designed and assembled. This was intended to give a primitive idea of electronic counting to the engineering undergraduates who were not exposed to them before. In fact, the counter was supposed to be used as a teaching guide to teach the students automated motion controlling of machines. The block diagram of the four digit counter is shown in Figure 7-5. SENSOR AMP PHOTO CELL LED Interrupt point to increment count SCHMITT TRIGGER CD4026 SSD DRIVER 7 8 SSD LM324 CLK input of next CD4026 Figure 7-5 Electronic Rotation Counter CD4026 is a decade counter and can drive a seven segment display (SSD) directly. The carry out pin of one IC is fed to the clock input of the next IC so that the count of next stage is incremented by 1 for 10 counts of this stage. LM324 contains four general purpose operational amplifiers and used for the photo cell signal amplification and as a Schmitt trigger. 34 CHAPTER 8: ANNUAL PHYSICAL VERIFICATION OF STORES At the end of each year, a physical verification of the stores is usually conducted and an inventory of items and prices is made. The Annual Physical Verification Of Stores as at 31st December 1995 contained 1889 items listed alphabetically. The value of the items was Rs. 1 570 074. 61. The price of the condemned items was Rs. 44 397. 83 during the year. It is interesting to note that the prices of the items were put as the prices existed when they were bought. For example a set of allen keys was only Rs. 25. 00 the present value being around Rs. 600. 00. In this sense, the present value of the stores might be around 40 million rupees. Usage of past prices of items in the inventory has no value at all. It just shows the total expenditure for the stores from the past. It would have been much more useful if the present prices of the items were used in the inventory. 35 CHAPTER 9: ADMINISTRATION, MANAGEMENT AND WELFARE 9. 1 UNDERSTANDING THE ATTITUDES OF EMPLOYEES Understanding the attitudes of employees is one of the most important aspects an engineer should gain in his currier. Collaborating with employees with different mentalities is inherently difficult. Some of the points that were possible to discover are listed below. Different employees have different expectations from their jobs: Faithful earning to live the life. Just earning money to live the life. Earning some extra money. Acquiring experience for a better job position. Acquiring the name of the current working organization in his curriculum vitae for a better job. While coming to the work, employees come with different mentalities: Fresh mind and pleasure to work. Burdened mind and unpleasant to work. Different personalities: Living with the community. Showing the existence. 9. 2 JOB DISPATCHING AND ADMIRING THE WORK Faithful job dispatching among the employees in the organization makes the environment pleasant for the employees to work and the administration becomes easier. In the Engineering Workshops job dispatching was done by the Workshop Engineer. Though the organization had excessive human resources and workmen were given less tasks than they could carry, in some cases it was seen that some workmen saying â€Å"I have been given more work than others†. Some even said, â€Å"Since I am the only person who knows the subject I am always burdened with the work†. It was interesting to find out whether they state the truth. In response to these statements a secret survey was conducted. Four workmen were selected including the ones who said that they were burdened and their work was observed in intervals of 15 minutes for two days. The results showed that they just lie. Some were not even possible to find for hours. One just signed the attendance register in the morning and evening and did nothing at all. Not a single was found to work at least quarter the nominal time period. 36 On the other hand, persons in the tool stores were truly burdened with work. They had to serve others all the times. In fact they disliked working there. Whatever the case it was seen that workmen always tried to show the Workshops Director that they work. When the Director was not near by, workmen did there work in lethargy. This was discussed with the Director and the final point was: â€Å"Yes, they want to show their boss that they work. Though a very little work is done, they are quite happy to be admired by me. † In any case, accepting feedback from the employees and acting on them necessarily upholds the productivity of any organization. CONTROL EMPLOYER FEEDBACK Figure 9-1 Listening To Feedback From Employees EMPLOYEE 9. 3 GUIDE LINES FOR BETTERMENT In some places of the Engineering Workshops guidelines for improving the performance of workmen could be found. Among them the ones that most people did not follow and the ones that should be followed are listed below: Keep your eyes on the man ahead – you may be called on to take his place some day. Read one or two of the technical magazines related to your line of work. It was unfortunate to say that most guidelines were in English and many workmen did not understand them. Furthermore a discussion with the Workshops Director revealed that earlier there were some sessions for the employees about implementing the Japanese S5 Concepts in the Workshops and they just died. Later he was seen refreshenning it by dividing the Workshops area among the workmen and allocating each area to several employees to maintain the enclosed machines. In Figure 9-2, the thick lines indicate the boundaries of the divided areas. 37 Figure 9-2 Division Of Flow Areas To Implement The Japanese S5 Concepts 9. 4 FREEDOM AND WELFARE SOCIETIES WITH POLITICS In the Engineering Workshops several welfare societies could be found. The Engineering Workshops Welfare Society united all the workmen in the Engineering Workshops. Furthermore some welfare societies formed at the university level could be found. Unfortunately these societies were heavily based on the political parties of the country. Depending on the political party one likes, he may join the related society. Freedom is lost and people get framed with the political party the

â€Å"Group Theory and Group Practice† Group theory is defined as scholar’s studies/ interpretations of group communication. Group practice is defined as ones participation and activities in a particular group. Both of these involve one central component which is group communication. A good leader must ensure effective communication amongst members promoting proper message exchange and information flow while discouraging group discord that would result in group failure and collapse. One of the largest issue issues in today’s society is effective leadership. Everyone knows that they want to be in charge and lead the group, but who knows what being an actual effective leader involves? Without good communication the flow of information among members is deterred and messages do not get across. It is critical that a good leader displays the ability to communicate with their associates as well as their subordinates in an effective manner. They must also be able to train as well as encourage others to follow in their footsteps when it comes to effective communication. An effective leader must be able to cope with all types of challenges when it comes to effective communication. One of the more prominent challenges that are arising is diversity. Cultural differences such as customs and beliefs are some of the challenges that leaders have to deal with. A good leader will be able to embrace these differences rather than allow them to become a handicap.

Joseph Stalin Research Paper Example | Topics and Well Written Essays - 2750 words

Joseph Stalin - Research Paper Example For instance, according to statistical estimates provided by Haynes and Husan in their book A Century of State Murder? Death and Policy in Twentieth-Century Russia, if the 1920s mortality rates are to be extrapolated to the 1930s, one has to reach a conclusion that there were about 8.5 million excessive deaths for 1928-1936, and additional 1.5 million for the second part of the decade of the 1930s, making total number of casualties of Stalinism in the 1930s close to 10 million people (Haynes and Husan 65). If one compares the population predictions for the year of 1937 compiled by Soviet Gosplan in the late 1920s (about 181 million people) with the 1937 census’s actual results (i.e. 168.5 million people, further reduced to 167 million by the new 1939 census), it is clear that Soviet population fell by considerable number in the 1930s, as even Stalin’s government was forced to concede (Haynes and Husan 64). This tremendous number of excessive unnatural deaths should be f urther extended by taking into account the number of deaths of Soviet soldiers and citizens in the course of WW II, which, while not entirely caused by Stalin’s military ineptness, were significantly increased by it. In addition, the death rate in Soviet forced labor camps rose to its highest level in the 1940s, with 1.01 million of dead prisoners in 1941-1945 (Haynes and Husan 83). Finally, the 1940s deportations of national groups deemed not loyal to the Soviet regime cost their own share of deaths: almost 300-400.000 are likely to have perished, as the data provided by Pohl testify (2). This means that in all certainty, Stalinism led to deaths of about 20 million people, if the part of wartime deaths is included in overall estimate. Nonetheless, despite the natural aversion that may arise towards Stalin and his system of government when exposed to such information, it is known that memories of Stalinist era are often fondly invoked in modern Russia and, to a lesser extent, in other post-Soviet states. In particular, Putin’s government often uses memories of Stalin’s rule to support its own actions, especially un the field of foreign policy, and the new history textbooks used in Russian schools often include statements of the like that â€Å"Stalin acted ‘entirely rationally’ in executing and imprisoning millions of people in the Gulags† (Stewart). The nature of such fondness for Stalin on the part of Russian authorities is understandable, as the Russian government, while pursuing harsh neo-liberal economic policies, widely employs appeals to ‘Soviet nostalgia’ in its symbolism and external policies. At the same time, a characteristically different kind of ‘popular Stalinism’ exists among the wide strata of Russian society. Exemplified by the policies of ‘red-brown’ Communist Party of Russian Federation, which for all purposes dropped its former Marxist tenets in favor of more op en Russian imperial patriotism and of other, smaller but ideologically similar parties and groupings, this type of ‘Stalinist’ feelings mix nostalgia for the ‘orderly’ society unaffected by market turbulence with strong cultural conservatism and xenophobia. Therefore, despite strong condemnation levied upon Stalinism by Russia’s liberal intelligentsia, Stalinist sentiment, or,

United Nations Conventions on Contract Essay Example | Topics and Well Written Essays - 3250 words

United Nations Conventions on Contract - Essay Example In the first case under consideration, SamCo & DeanCo appear to be the parties to the contract, where a deal in respect of buying and selling five dark blue bonnets was to be executed. Similarly, the second case looks for giving legal advice to the above-described Swedish company SamCo in respect of its deal with the Brazilian reseller company CastielCo. However, before embarking upon the topic under consideration, and providing them with a piece of advice in the light of the Vienna Convention on and International Sale of Goods Contracts, it would be advisable to elucidate the terms that create responsibilities and liabilities to the parties to the contract, in order to explore whether or not any contract has been entered into between the parties, could bind them to execute some specific performance, which is as following: The 1980 Vienna Convention1 provides the parties to the contract with a complete and wide-ranging procedure while entering into a legal relationship between one an other during foreign trades and business ventures. The main objective behind the Vienna Convention includes the protection of the rights and privileges of the individuals on the one hand and enforcement of the promises and agreements the individuals and parties have entered into2 at the international scale on the other. ... nce, deceit and misrepresentation.3 In addition, 1980 Vienna Convention also protects the rights of the people who have either not entered into any contract with the persons and organisations outside their countries, but are falsely claimed to be having entered into the same. Consequently, 1980 Vienna Convention also endorses the statutes of Contract Law, which have defined and determined some conditions, fulfilment of which is vehemently necessary for a valid contract. â€Å"An agreement†, according to section 2 (h) of the English Contract, â€Å"creating obligations to the parties, and enforceable at law is a contract†4 Young (2010) has defined contract in these words: â€Å"A contract is an agreement (usually between two persons) giving rise to obligations on the part of both persons which are enforced or recognised by law†.5 Consequently, social contracts do not create legal enforcement due to the very fact that there is no intention of any legal remedies aga inst non-fulfilment of the same. The same is also applied to the international contracts, all of which aim to create legal responsibilities on the parties to the contract. Vienna Convention, according to its statutes, applies to contracts of sale of goods between parties whose places of business are in different States.6 In order to comprehend with the elements of an international contract, it is essential to explore the basics of an agreement. According to English Contract Law, â€Å"Every agreement is a contract if it is made by the free consent of the parties, competent to contract for a lawful consideration and with a lawful object, and not hereby expressly declared to be void.†7 In other words, a valid contract maintains the following elements in it; accomplishment of all of them is essential for making it an

Process Of Unstructured Clinical Judgement Health And Social Care Essay

Process Of Unstructured Clinical Judgement Health And Social Care Essay However, there continues to be an increasing  interest  and  expectation  on professionals from the public and the criminal justice system in regards to the potential  danger  posed by  serious  offenders  being released  back into the community and the need for the offenders to be better managed, in order  to adequately protect  the public from dangerous individuals (Doyle et el, 2002). As the assessment of risk  is made  at various stages in the management process of the violent offender, it is  extremely  crucial that mental health professionals have a structured and consistent approach to risk assessment and evaluation of violence. (Doyle et el, 2002). This paper will examine three models of risk assessment that  are used  to reduce potential danger to others, when integrating violent offenders back into the community. These three approaches are unstructured clinical judgement, structured clinical  judgement  and actuarial  assessment. It is not intended, in this paper, to explore the various instruments used in the assessment process for the  respective  actuarial and structured clinical approaches. Unstructured Clinical Judgement Unstructured clinical judgement is a process involving no specific guidelines, but relies on the individual clinicians  evaluation  having regard to the clinicians experience and qualifications (Douglas et al, 2002).  Doyle et el(2002, p650) refers to  clinical  judgement as first generation, and sees clinical judgement as allowing the clinician  complete  discretion in relation to what information the clinician will or will not take notice of in their final determination of risk level. The unstructured clinical  interview  has been widely criticised because it  is seen  as inconsistent and inherently lacks structure and a  uniform  approach  that does not allow for  test, retest reliability over time and between clinicians (Lamont et al, 2009). It  has been argued  that this inconsistency in  assessment  can lead to  incorrect  assessment of offenders, as either high or low risk due to the subjective opinion inherent in the unstructured clin ical assessment  approach  (Prentky et al, 2000). Even with these limitations discussed above the unstructured clinical  interview  is still likely to be the most widely used  approach  in relation to the offenders violence risk assessment (Kropp, 2008). Kropp (2008), postulates that the continued use of the unstructured clinical  interview  allows for idiographic analysis of the offenders  behaviour (Kropp, 2008, p205).  Doyle et al (2002) postulates, that clinical studies have shown, that clinicians using the risk analysis  method  of unstructured interview, is not as  inaccurate  as  generally  believed.  Perhaps this is due, largely to the level of experience and  clinical  qualifications of those conducting the assessment. The unstructured clinical  assessment  method  relies heavily on verbal and non verbal cues and this has the potential of influencing individual clinicians assessment of risk, and thus in turn has a high probability of over reliance in the assessment on the exhibited cues (Lamont et al, 2009).  A major flaw with the unstructured clinical interview, is the apparent lack of structured standardized methodology  being used  to  enable  a  test  retest reliability  me asure  previously mentioned.  However, the lack of consistency in the assessment approach is a  substantial  disadvantage in the use of the unstructured clinical interview.   The need for a more structured  process  allowing for  predictable  test retest reliability would  appear  to be a  necessary  component of any risk assessment in relation to violence. Actuarial Assessment Actuarial  assessment  was developed  to  assess  various risk factors that would improve on the probability of an offenders recidivism. However, Douglas et al (2002, p 625) cautions that the Actuarial  approach  is not conducive to violence prevention. The Actuarial approach relies heavily on standardized instruments to assist the clinician in predicting violence, and the majority of these instruments  has been developed  to predict future  probability  of violence amongst offenders who have a history of mental illness and or criminal offending behaviours. (Grant et al, 2004) The use of actuarial  assessment  has increased in recent years as more non clinicians  are tasked  with the responsibility of management of violent offenders such as community corrections, correctional officers and probation officers. Actuarial risk assessment methods enable staff that do not have the experience,  background  or necessary  clinical  qualifications to  conduct  a standardised clinical  assessment  of offender risk. This actuarial  assessment  method  has been found  to be extremely  helpful  when having risk assessing offenders with mental health, substance abuse and violent offenders. (Byrne et al, 2006). However, Actuarial assessments have limitations in the inability of the instruments to provide any information in relation to the management of the offender, and strategies to prevent violence (Lamont et al, 2009).  Whilst such instruments may provide transferable  test  retest reliability, there is a need for caution when the instruments  are used  within differing samples of the  test  population  used as the validation  sample  in developing the  test  (Lamont et al, 2009).  Inexperienced and  untrained  staff  may not be aware that tests  are limited  by a range of variables that may limit the reliability of the test in use. The majority of actuarial tools  were validated  in North America (Maden, 2003). This has  significant  implications when actuarial instruments  are used  in the Australian context, especially when indigenous cultural complexities are not taken into account. Doyle et al (2002) postulates that the actuarial  approach  are focused  on prediction and that risk assessment in mental health has a much broader  function  and has to be  link  closely with management and prevention (Doyle et al, 2002, p 652). Actuarial instruments rely on measures of static risk factors e.g. history of violence, gender, psychopathy and recorded so cial variables.  Therefore, static risk factors  are taken  as remaining constant.  Hanson et al (2000) argues that where the results of unstructured  clinical  opinion  are  open  to questions, the empirically based risk assessment  method  can significantly predict the risk of re offending. To rely  totally  on  static  factors that  are measured  in Actuarial instruments, and not incorporate dynamic risk factors has led to what Doyle et al (2002) has referred to as, Third Generation, or as more commonly acknowledged as structured professional judgement. Structured Professional Judgment Progression toward a structured professional  model, would  appear  to have followed a process of evolution since the 1990s.  This  progression  has developed through  acceptance  of the complexity of what risk assessment entails, and the pressures of the courts and  public  in developing an expectation of increased predictive accuracy (Borum, 1996).  Structured professional judgement brings together empirically validated risk factors, professional experience and contemporary knowledge of the patient (Lamont et al, 2009, p27).  Structured professional judgement approach requires a  broad  assessment  criteria covering both static and dynamic factors, and attempts to bridge the gap between the other approaches of unstructured clinical judgement, and actuarial  approach  (Kropp, 2008).  The incorporation of dynamic risk factors that are taking  account  of variable factors such as current emotional  level  (anger, depression, stress), social supports or lack of and willingness to participate in the treatment rehabilitation process.  The structured professional approach incorporates  dynamic  factors, which  have been found, to be also crucial in analysing  risk  of violence (Mandeville-Nordon, 2006).  Campbell et al (2009) postulates that instruments that  examine  dynamic risk factors are more  sensitive  to  recent  changes that may  influence  an increase or decrease in risk potential. Kropp (2008) reports that research has found that Structured Professional Judgement measures also  correlate  substantially  with actuarial measures. Conclusion Kroop, (2008) postulates that either a structured professional judgement approach, or an actuarial approach presents the most viable options for risk assessment of violence.  The unstructured  clinical  approach  has been widely criticised by researchers for lacking reliability, validity and accountability (Douglas et al, 2002). Kroop, (2008) also cautions that risk assessment requires the assessor to have an appropriate level of specialized knowledge and experience. This experience should be not only of offenders but also with victims.  There would  appear  to be a valid argument that unless there is consistency in  training  of those conducting risk assessments the validity and reliability of any measure, either actuarial or structured professional judgement, will fail to  give  the  level  of predictability of violence that  is sought.  Risk analysis of violence will always be burdened by the  limitation  which lies in the fact that  exact  an alyses are not  possible, and  risk  will never be totally eradicated (Lamont et al, 2009, p 31.). Doyle et al (2002) postulates that a combination of structured clinical and actuarial approaches  is warranted  to assist in risk assessment of violence. Further research appears to be warranted to improve the evaluation and  overall  effectiveness of risk management.

Heart of Darkness Critical Paper Essay

Joseph Conrad’s novel, Heart of Darkness, is a work of complexity. â€Å"His stories often represent and suggest more than they say† (Skinner). Conrad gives the novel a perplex side through his tactfully written words. This unique language that Conrad uses gives a sense of duality to many phrases in the novel. The double meanings of much of the language that Conrad uses contribute to a reoccurring aspect of the novel, which is that often times there is far more substance to something than appears on the surface. This theme is played out in the novel through the setting and through the two main characters, Marlow and Mr. Kurtz. The novel takes place right in the heart of Africa, down the long and windy Congo River. The river in the setting is a crucial component of the novel because it brings a sense of darkness. â€Å"Conrad manages to hint at the darkness beyond the senses and to represent the experience of struggling with the impossibility of existential revelation in various ways, in terms of both content and form,† because not only does he describe the river’s topography, but also describes the river as having a mind of its own (Skinner). When describing the river, Conrad writes, â€Å"the long stretches of the waterway ran on, deserted, into the gloom of overshadowed distances†(Conrad). This description of the river creates an image of a vast and gloomy river. However, Conrad’s use of personification gives the river a personality, as if it is vulnerable to the dark surroundings that it’s engorged within. In the novel, Marlow’s spoken words also possess a sense of duality. On the outside, Marlow seems like a composed gentleman, who takes little regard for emotions. He speaks in a matter of fact manner, describing everything that he sees in its purest form. When conveying his thoughts about Kurtz he says ,â€Å"He was just a word for me. I did not see the man in the name any more than you do†(Conrad). Marlow’s description of Kurtz at first seems merely a factual statement, but it means more than that because â€Å"there is what is not said because it is merely left unstated (Skinner). The understated nature of his words suggests that Marlow is struggling to compress everything that he feels about Kurtz into a sentence. Furthermore, when Marlow says, â€Å"I will be loyal to the nightmare of my choice†, the reader obtains two meanings from his words (Conrad). On the exterior, Marlow simply means that he will not betray Mr. Kurtz, but on the interior, he is trying to express that he will not let go of the desire that he had to meet Mr. Kurtz, even though the experience strayed far away from his original expectations. Conrad also uses Mr. Kurtz to showcase his way of writing phrases that contain different depths of meaning. Mr. Kurtz is an individual who unknowingly lost sight of his own self because of the heart of darkness in which he is enwrapped. He is unable to blatantly express how his greed and feelings of superiority over the natives have tarnished his character. Therefore, Conrad gives depth to the words that Kurtz speaks, to allow the reader a glimpse into Kurtz’s heart, without needing to have Kurtz deliver his personal sentiments. Towards the end of the novel when Kurtz cries, â€Å"save me!† he literally is pleading for the salvation of his ivory, but figuratively, it’s a plea for someone to save his soul. â€Å"The Horror! The Horror!† are Mr. Kurtz’s notorious last spoken words. On the surface, these words may appear to be describing the face of death, but it seems plausible that Kurtz’s is instead horrified with himself for the way he has so cruelly treated the natives, and that abominable images of the native’s oppression are flashing before his eyes. The duality in meaning of Conrad’s words not only contributes to the complexity of the novel, but also helps to develop the setting and the characters. Conrad’s â€Å"unsaid dialogue and narrative hint at layers of meaning beyond what is read, and Conrad’s explicit and implicit insistence on mysteries beyond words emphasize the unsayable†(Skinner). These techniques that Conrad uses allows the novel to transcend past a simple narrative.(Singer)
