PYC4811 Assignment 1- 657794 Student Number- 55560296 Community Psychology and Public Health’s Approaches to Social Problems Introduction Community Psychology and Public Health models both cover the same ground but with key differences in the explanation of causes and influences on mental illness. Community psychology has a primary focus on understanding, and working with, people in their wider social context. Public Health on the other hand is concerned with preventing disease and distress of all forms before they occur (Tutorial Letter 102 for PYC4811, 2015). It attempts through scientific investigation to understand such links between the socioenvironmental context and the individual and then to interrupt or otherwise†¦show more content†¦Community psychology differs in that it believes the development of pathology is the result the oppressive socio/politico/economical structures and systems (Guernina, 1995). Pathology is the result of an individual being forced to survive in an environment of poverty and violence all of which lead to maladaptive behaviour developing in order to cope with these environments (Gilbert, 1995). Both public health and community psychology are each based on four different models. Public health concerns itself with the physical and tangible changes within the environment such as sanitation and hygiene and the regulation of the food industry as well as health services (Tutorial Letter 102 for PYC4811, 2015). In contrast community psychology concentrates mainly on the development of economic and psycho/social skills with the idea that by taking note of the effect of these social variables on development and growth, that competencies and coping skills can be developed and taught to help reduce the negative impact of these variables and promote positive coping behaviours (Seedat et al, 1988). Shortcomings and Strengths of the Models Both models have elements of strength and weakness. Strengths of using community psychology is that your research can be action-driven and can be planned to guide practices, policies and procedures to have a beneficial impact on people’s lives (Williams, 2015).

A Life Of Tranquility The One For Me - 1267 Words

A life of Tranquility: The One for Me? I. Introduction In opposition to hedonism, some philosophers have argued that the most pleasant life is a life of tranquility. Whereas hedonism is highlighted by being pleasure driven; the tranquil lifestyle is driven by maintaining a static pleasure. With this in mind it becomes clear that one way to evaluate how philosophers argued if a tranquil life was the most pleasant life would be to compare the two. Three aspects that can be evaluated are the fact that a life of tranquility is one of a life of prudence, it is simple lifestyle, and it is forward looking all of which I hope to explain in more detail throughout this paper. II. A life of Prudence My first attempt to understanding, how a life of tranquility may be the most pleasant life is to understand the concepts behind a life of tranquility along with understanding a hedonic lifestyle. In doing this I hope to lay the groundwork to further explore how these two interact with each other. According to Epicurus, a life of tranquility is one where a person (for the sake of the paper we will follow the character Christian) achieves happiness by maintaining static pleasures. The point of maintaining static pleasures serves a two-fold purpose. The first is that if Christian were to seek non-necessary pleasures (desiring a bigger car/bigger house), he would begin to desire them and work for them more. Eventually however, this would lead to pain (his car breaks or there a newer model heShow MoreRelatedDoes Skepticism Bring Tranquility?751 Words   |  3 PagesIn this paper I will argue that the skeptic ideal for tranquility is incorrect. I will do this by presenting the case that the skeptics have not found true tranquility and that a person who holds the opinion that things can be good or bad is not always more troubled than one who does not. In this paper I am arguing against the skeptic work of Sextus Empiricus. Specifically his claim that tranquility is achieved solely through suspension of judgement and â€Å"a person will always be troubled if he holdsRead MoreThe Beauty Of Nature By William Wordsworth972 Words   |  4 Pageshis works.

When available the civil war sawboness put Chloroform on a fabric, so the fabric was held over the victim ‘s oral cavity and nose until the individual became unconscious. Because of the big figure of hurt soldiers the sawboness became experts with amputations, most of the clip the amputations could be performed in approximately 10 proceedingss. The sawboness were non healthful, because there was a deficit of H2O therefore they made no effort to rinse custodies or instruments between surgeries, despite all of this the survival rate of the amputees was at about 75 % . The bulk of the Civil War sawboness learned this process from this book â€Å" The Practice of Surgery † , by Samuel Cooper. This book was the â€Å" How To † book of executing amputations for the sawbones s. This book discusses the measure by measure ways to cut off the leg, below the articulatio genus, the arm, and the fingers and toes. Some of the instruments that the Civil War sawboness used were the compression bandage, scalpels, bone proverb, and bone childs. The compression bandage was used to curtail the flow of blood during an amputation process. The scalpel was used to do scratchs in the tegument. The bone proverb were used to cut straight through bone, and musculus. The bone childs were used to take matchwoods from the bone that the bone proverb could hold caused. Today there are many different types of amputations ; they are first categorized under upper limb amputations, and lower limb amputations. The upper limb amputations include: amputation of single figures, multiple digit amputation, metacarpal amputation, wrist disarticulation, forearm ( trans-radial ) amputation, elbow disarticulation, above-elbow ( trans-humeral ) amputation, shoulder disarticulation, and forequarter amputation. Amputation of single figures is the remotion of a finger ; this will do the patient problem hold oning objects. Multiple digit amputation is the remotion of two or more fingers, hold oning ability may be aided if the sawbones is able reconstruct the musculus. Metacarpal amputation is the complete remotion of the manus, with the carpus still integral ; with this type of amputation there is no ability to hold on. Wrist disarticulation is the remotion of the full manus up to the degree of the carpus articulation. Forearm ( trans-radial ) amputation this is the remotion radius, it is classified by the size of the staying stump ; as the stump length decreases so does the ability for the patient to revolve their forearm. Elbow disarticulation is the remotion of the full forearm up to the cubitus ; the patient still has the ability of keeping weight. Above-elbow ( trans-humeral ) amputation is the remotion of the humourous anyplace above the cubitus and below the shoulder ; prosthetic device could be used if there is some length left on the humourous. Shoulder disarticulation is the remotion the of the full arm, the shoulder blade still remains and the collar bone may or may non be removed. Forequarter amputation is the remotion of the full arm, shoulder blade, and collar bone, normally some bone is left in order to attach a prosthetic devices. The lower limb amputations include: foot amputations, ankle disarticulation ( Syme amputation ) , below-knee ( trans-tibial ) amputation, knee-bearing amputation, above-knee ( trans-femoral ) amputatio n, and hip disarticulation. Foot amputations are the remotion of any portion or part of the pes including toes, and mid-tarsal ; this type of amputation may impact balance and walking. Ankle disarticulation ( Syme amputation ) is the remotion of the full mortise joint ; with this type of amputation the victim can still mobilise without a prosthetic devices. Below-knee ( trans-tibial ) amputation is the remotion of the shinbone above the mortise joint, but below the articulatio genus ; victims keep the usage of the articulatio genus, but have problem seting weight on the stump. Knee-bearing amputation is the complete remotion of the lower leg ; it is normally more hard to make a prosthetic device for this type of amputation. Above-knee ( trans-femoral ) amputation is the remotion of the thighbone up to the degree of the thigh ; the victim can still sit with this type of amputation. Hip disarticulation is the remotion of the full leg ; sawboness try to go forth every bit much of the t highbone as possible in order to attach a prosthetic device. With all the amputations, upper and lower appendages, the sawbones will seek to go forth every bit much bone as possible in order to attach a prosthetic device. In the United States entirely there are over 350,000 amputees, and over 135,000 amputations happening each twelvemonth. In the United States the taking cause for amputations is disease ( 70 % ) , the 2nd leading cause is trauma ( 22 % ) , inborn or birth defects ( 4 % ) , and tumours ( 4 % ) . The most common diseases and conditions that can do an amputation are peripheral artery disease, arterial intercalation, impaired circulation as a complication of diabetes mellitus, sphacelus, terrible cryopathy, Raynaud ‘s disease, and Buerger ‘s disease. More than 90 % of all disease doing amputations are due to circulative complications of diabetes. 60-80 % of all of these amputations involve the lower appendages. Peripheral arteria disease causes amputations by the blood vass indurating that causes the blood to be blocked from making tissues in the organic structure ‘s appendages ; because of this these tissues finally die, which causes the demand for an amputation. Arteri al intercalation causes a blood coagulum to organize which blocks the flow of blood and so causes the tissue to decease and necessitate to be amputated. You read "History Of The Amputation Procedure Health And Social Care Essay" in category "Essay examples" Diabetess mellitus is a disease where non adequate insulin is produced by the organic structure and hapless circulation occurs as a consequence of the diabetes, the hapless circulation can do tissue to decease, which would so necessitate to be amputated. Gangrene is the decease and decay of one time living tissue, the dead tissue is removed through an amputation. Frostbite is when tissue on the organic structure freezes, ensuing in hoar bite, in terrible instances the tissue dies and so would hold to be removed through an amputation. Raynaud ‘s disease is a disease largely found in immature adult females, it causes reduced blood flow to the appendages ; this could so do the tissue in the appendages to decease. Buerger †˜s disease is a episodic disease that causes redness and obstruction of the venas and arterias of the appendages, normally merely occurs in work forces under age 40, who smoke, this disease may necessitate amputation of the custodies or pess. The 2nd prima cause of an amputation is trauma. Harmonizing to Merriam-Webster injury is an hurt ( as a lesion ) to populating tissue caused by an extrinsic agent. There are many different possible injury, they can happen with but are non limited to auto accidents, terrible Burnss and gunshot lesions. During a traumatic hurt, blood vass and other organic structure tissue constituents are ripped or torn beyond fix by these types of hurts, go forthing no other option but amputation. Another cause of an amputation is a congenital or birth defect amputation. Congenital amputations occur in the uterus while the babe is still developing ; blood flow to a limb can go restricted because of other tissue. As a consequence the limb could be lost and the babe is born with a inborn amputation. The other cause of amputations are by tumours. Peoples with malignant neoplastic disease that have malignant tumours, need to cut off the country in which the tumour is, in order to forestall the malignant neoplastic disease to further spread to other parts of the organic structure. Undergoing an amputation has many effects on the organic structure, both psychological and physical. These effects are happening before and after the surgery. Many new amputees have a hard clip with covering with the loss of a limb which has been with them since birth, merely the idea of holding to work without something that you have had entree to your whole life is a traumatic event in of its ego. When people are told that they are traveling to necessitate an amputation the most common reaction is shock. Many of the victims go through a period of denial, the people think â€Å" this ca n’t go on to me † or â€Å" I wo n’t allow you make this to me. † Many amputees may besides develop choler towards themselves, loved 1s and God. Amputees think to themselves â€Å" why me? † Many of the new amputees face being worried about the hurting during surgery and during the recovery period. Before the surgery the patients try to â€Å" dicker † with G od, the sawbones, or both to halt the demand for the amputation. After this does n’t work many times the patient begins to hold symptoms of depression. Most people in the terminal learn to get by with the loss of their limb and accept what has happened. The amputation will hold a important impact on the patient ‘s self image, which could be positive or negative. Some of the amputees may experience a greater feeling of strength developed in the attempt to get the better of the losingss which have occurred late in their life. A good thing for amputees is run intoing with other amputees to assist each other header. However this new ego imagine of themselves could besides be negative if the amputee is concerned about how people will comprehend them, because they feel that they need to affect. Many are besides concerned because they feel that they wo n’t be respected because they are crippled. Just like people need clip to retrieve psychologically and emotionally, the amputees need to retrieve physically. After the process, the patient will necessitate to be prescribed pain medical specialty, and antibiotics in order to forestall an infection from happening. The amputated part demands to be moved in order to make good circulation. The patient normally will get down physical therapy within 48 hours after surgery, to advance a speedy and effectual recovery. Depending on the gravitation of the amputation, depends on the clip that the patient will pass in the infirmary, it normally varies from several yearss to two hebdomads. Rehabilitation is a long procedure for amputees. Patients with an upper appendage amputation will most likely work with an Occupational Therapist. Patients with a lower appendage amputation will most likely work with a Physiotherapist/Physical Therapist. The clip that a recovery takes depends on assorted factors such as: physical form before the amputation, age, other medical jobs, ability to larn how to utilize a prosthetic de vice, how good you follow waies, motive to retrieve, and your psychological province. As with any major surgical process, amputations have major hazards with undergoing with this process. Hazards with the anaesthesia exists, every bit good as the possibility of heavy blood loss, and the possibility of blood coagulums organizing. Another major hazard of the process is infection to the amputated part. The rate of infection is at approximately 15 % , if the stump were to go septic the prosthetic device would hold to be removed and perchance a 2nd amputation higher up the appendage. Another major hazard is the stump neglecting to mend. This normally happens when there is a deficiency of blood to the amputated limb. Another hazard is phantom limb hurting, which is hurting that feels like it ‘s coming from a organic structure portion that ‘s no longer at that place. The intervention to phantom limb is hard, but it is possible. New amputees will sooner or subsequently have to confront that it will be harder to make the mundane undertakings that they used to finish. Although most of these undertakings are more hard, they are n’t impossible, because of prosthetics. From the clip that amputations started, there were prosthetic device for the losing limbs. The prosthetic device were every bit simple as a wooden leg in the clip of early prosthetics. Today as engineering has advanced from the clip of early prosthetics, so has the prosthetic device made for amputees. Today there are prosthetic device that can pick up urges from the nervus that are amplified into a motor that make the elbow crook or unbend out, or the fingers open and near. For above the articulatio genus patients there are new prosthetic device which use motion-tracking detectors, vacuity suction engineering to supply improved tantrum, comfort and control. Since the recent promotions of these new prosthetic device people can populate simila r to the life that they used to populate. Amputations are a minor reverse for some unbelievable people who have gotten through their calamity, and have become noteworthy people in the universe of amputees. Heather Mills was the former married woman of Beatle Paul McCartney ; she was besides an English militant and a former glamor theoretical account. In August of 1993, Mills was hit by a constabulary bike while traversing the route, her hurts included crushed ribs, a pierced lung, and terrible hurt to her left leg. She needed a metal home base put into her pelvic girdle and the amputation of her leg below the articulatio genus. Bethany Hamilton is an American surfboarder who survived a shark onslaught in where she lost her left arm ; she overcame the serious and debilitating hurt and returned to surfing. Her narrative was so inspiring that there is a film that was late released about her called â€Å" Soul Surfer † .

Foundations of Management Organizational Internal Communication

Question: Describe about the Foundations of Management for Organizational Internal Communication. Answer: Introduction The purpose of this paper is to emphasize the importance of information in business decision-making. In this era of competitiveness, an organization needs to strengthen their internal and external communication in order to gain superiority in market. Therefore, it is highly important to maintain information flow with the internal and external stakeholders (Shockley-Zalabak 2011). The focus of this paper is to identify three examples of business disaster due to lack of information flow. In order to maintain information flow, it is highly important to understand the need of stakeholders and the frequency with which information needs to be delivered. Inadequate information flow creates dilemma among the stakeholders of an organization. Discussion Information plays a major role in maintaining business sustainability. Inadequate information has a negative impact on the decision-making of a business. For example, Lehman Brothers, a financial service provider firm has declared bankruptcy in 2008 due to lack of information (Lehman.com 2016). Apart from that, Enron Corporation is another example of business disaster due to lack of information. The largest an energy-trading company has declared as bankrupt in 2001 (News.bbc.co.uk 2016). The third example in this case is Woolworths has recently declared a record of annual loss of AUS $2.1 billion (BBC News 2016). The above discussed cased are due to lack of information flow within the stakeholders. Case 1: Lehman Brothers Bankruptcy In this case, the company was unable to maintain the information flow among the stakeholders. The major issue of the company was inadequate information about the mortgage crisis. The company was unable to maintain organizational data, which was highly important in order to take organizational decision. During the final phase, the company has implemented cost-cutting approaches through reducing workforce (van Osch, Steinfield and Balogh 2015). However, the company could have improved communication among the employees in order to recover the critical situation. Here, management theory of Elton Mayo would be the most relevant to discuss the massive failure of the company. According to this theory, employees need motivation in order to achieve their objectives in an efficient manner (Holmberg and Hellsten 2016). On the other hand, financial motivation is not only the motivational tool, which management of an organization can implement. Instead, the company should communicate with the emp loyees in order to motivate the workforce in an efficient manner. In case of Lehman Brothers, the company was already facing difficulties due to inadequate information. On the top of it, the company had implemented cost-cutting strategies by reducing workforce. Therefore, it can be said that the approach of the company was wrong (Cooren 2016). The company would have allowed the employees to share their viewpoint and decisions in order to overcome the situation. Additionally, the company would have shared necessary information with the workforce in order to reduce dilemma among the workforce. Mayos management theory has four combinations with which management can evaluate the workforce. The first dimension consists of employees with low cohesiveness and norms, which makes the workforce ineffective to handle critical situation. The second combination is low cohesiveness and high norms. Here, some employees can perform as per the organizational requirements (Karanges et al. 2015). The third combination is high cohesiveness and low norms. Here, some employees create a negative environment, which prevents others to perform. The fourth combination is high norms and cohesiveness. Here, employees can work collaboratively in order to achieve broad organizational objectives. Lehman Brothers would have understood the nature of workforce in order to improve information flow within the organization. When it comes to the relationship between the managers, the company fails to maintain collaborative management approach. Therefore, it was difficult for the company to understand requirement of the stakeholders. Moreover, managers of an organization should have sufficient control among the workforce (Alvarez, Bauer and Eger 2015). However, in case of Lehman Brothers, managers were unable to maintain sufficient information flow for which control among the workforce was weak. Case 2: Enron Files for Bankruptcy Enron was an energy-trading company, which was formed after the merge up of two gas companies such as Internorth and Houston Natural Gas. Under leadership of the CEO Kenneth Lay, the company had achieved lot of success in the year 2000. In this fiscal year, the company was in the seventh position among 500 US companies. The company had 21000 employees in this year and the annual revenue of the company was $111 billion. However, the companys stock price had dropped from $90.75 to $0.26 (News.bbc.co.uk 2016). Here, the company has misled the employees regarding the financial stability of the company. The company had also misled the investors regarding their financial weaknesses. In case of this company, employees were the shareholders and therefore, it can be said that the company has misled both the investors and employees, which led the company towards failure (Stahl 2016). Apart from that, the company had destroyed organizational documents in order to avoid legal consequences. After reviewing the business case, it can be said that inadequate information flow was the major issue for which the company had declared as bankrupt. In this scenario, Maslow human needs theory would be the most relevant theoretical discussion. According to this theory, management should empower motivation of the workforce through five dimensions. The goal of the management should provide adequate information to the workforce in order to achieve organizational goal. During the crisis period, the company would have communicated with the workforce and investors in an appropriate manner (Botana and Neto 2015). The employees were unable to understand the rationale behind rapid change in business process. When it comes to the employees, they were unable to accept the changes in management structure. Therefore, they were unable to reach to the self-actualization stage of Maslow hierarchy of need. The company would have communicated with the employees regarding the probable issues that the com pany was facing. In this manner, the company would be able to encourage the employees to give valuable recommendation to the company. A good flow of information and communication would allow the company to work collaboratively. Therefore, it can be said that the reason behind Enrons bankruptcy was lack of information flow among the stakeholders. Case 3: Woolworths Disaster Woolworths is the biggest supermarket chain of Australian market, which recorded a loss of AU $1.2 billion. However, in previous year the annual profit of the company was AU$ 2.1 billion. The reason behind this massive fall in sales figure was organizational communication. In this industry, it is highly important to work collaboratively in order to achieve overall organizational goal. In retail industry, employees should have proper information regarding store layout and products as well. In this manner, employees will be able to provide adequate information to the consumers (Shockley-Zalabak 2011). The downfall in annual profit was caused by the low managerial control. Therefore, Fayols principles would be the most effective theoretical framework to discuss the business scenario of Woolworths. In order to handle critical situation, managers of an organization should understand skills and abilities of the employees. According to the first element of Fayols theory, managers should hav e proper understanding regarding the work division. Authority is another element of this theoretical framework through which managers should have adequate command over the workforce. In case of Woolworths, the managers were unable to control the workforce for which they were unable to perform according to the performance benchmark. According to the discipline dimension, employees need a direct supervisor in order to work according to the requirements. In this manner, the company would be able to comply with the organizational policies and procedures, which is highly important for maintaining business sustainability (Holmberg and Hellsten 2016). In order to conduct efficient organizational decision, managers should understand the ability of the workforce. The leaders are solely responsible to allocate job role to the employees. Therefore, employee information is what managers require in order to take the final decision. However, in Woolworths, the managers were unable to understand t he key characteristics of the employees. Another element of this theoretical framework is remuneration (Karanges et al. 2015). In order to empower performance quality of the workforce, organization should provide satisfactory remuneration to the workforce. Apart from delivering information to the workforce, it is highly important to focus on employee motivation. On the other hand, an organization should provide adequate information to the employee in order to influence motivation positively (Cooren 2016). Therefore, it can be said that lack of information to the employees and lack of information regarding the key characteristics about employee performance was two major reasons for sales drop of the company. Conclusion While concluding, it can be said that information flow is the key success factor for organizations. In order to maintain efficient information flow, an organization should focus on the organizational culture. In this paper, three business cases have been evaluated, where the reason behind business disaster is lack of information flow. After conducting the evaluation, it can be said that managers should communicate with the external and internal stakeholders in order to provide adequate organizational information.

Music Forms That Defined the Baroque Era free essay sample

The end of the renaissance period brought several artists and intellects together to discuss the revival of the Greek drama. Although several forms from the renaissance were still used, the development of new styles evolved, especially In the area of vocal music. Opera, oratorio and the cantata came directly from the theatrical desire to Invoke the emotional awareness of their listeners through singing, while the concerto, sonata and suite gave the listener the ability to feel the conflict and harmony through instruments.Opera was made possible by the singing of poetic texts with a plot like function, achieving a distinctive advancement in the baroque musical scene. Its development was a step forward to the expanding music scene and gave a new view on the dramatic texts with musical enhancement. Opera is a drama that is sung with the accompaniment of instruments. Operas often have a long type speech that moves the plot along and expresses the characters feelings and emotions at specific points in the action. We will write a custom essay sample on Music Forms That Defined the Baroque Era or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The first operas were often taken from Greek myth, recreating the drama and music of the ancient culture. Two sub-genres of opera were developed In the early 18th century: opera serial and opera buffo. Opera seen focused more on the object matter while opera buffo used duets, trios and larger ensembles and were notably lighter and often comedic tones. The word oratorio originally meant prayer hall, a building adjacent to the church. The musical genre of the oratorio emerged in the late 16th century and focused on the subject of religious texts.Oratorios, unlike operas, perform without costumes, scenery or action and are often divided into two distinctive parts. Popular composers of the oratorio are J. S. Bach, Antonio Vivaldi, and George Frederic Handel. The cantata, in early history confused with oratorio, consists of recitatives and set ices which Include arias, duets and choruses often In religious context. The cantata, Like the opera, contains scenery and movement but also has dialogue. By the end of the 17th century cantatas were often accompanied by orchestras.Popular composers of the cantata are J. S. Bach, Lug Rossi, and George Frederic Handel. The sonata, often used as chamber music, can consist of one, two or three instruments, usually violins, a treble instrument and a bass instrument. They usually contain four movements which alternate between fast and slow tempos. In the 18th century instruments such as the organ and harpsichord were rising in the solo mantas. Popular composers of the sonata are J. S. Bach, Alexandra Scarlatti, and George Frederic Handel. During the baroque era the concerto took on several forms. They could consist of a simple composition that Included voices, instruments or a combination of both, sacred works for voices and instruments, and Instrumental soloists or groups with an orchestra. Popular composers of the concerto are J. S. Bach, Antonio Vivaldi, and George Frederic Handel. Antonio Vivaldi, the most notable composer of the solo concerto, wrote approximately 350 concertos and standardized the three movement form, which consists of two fast and one slow movement. Nor for instruments. The suite is basically a two part series of dances in the same key and can consist of three to twelve movements.

Louis XIV And His Foreign Policy essays

Louis XIV And His Foreign Policy essays Louis XIV (1638-1715), was known as the 'Sun King'. By the time Louis took up the reign of the government in 1660, France had turned into the most powerful nation of Europe. At this time many of France's neighboring countries had been weakened both by revolts within their own countries and expensive wars with other lands. In Louis's mind, the natural boundaries of France were the Alps, the Pyrenees, and the river Rhine. His intentions were to push the frontiers of France out to these limits as well as win glory for himself. As a result Louis plunged France into 30 years of foreign wars trying to achieve his ambition. This paper discusses Louis' XIV's foreign policy and analyzes whether his foreign policy was successful or not. Louis XIV's notorious dictum was "I am the State". Even the late Charles De Gaulle often echoed this. Louis XIV (1638-1715) - king of France (1643-1715) - was known as the 'Sun King'. Louis, the third monarch of the Bourbon family, ruled for 72 years, the longest reign in European history. His rule typified the period of absolute monarchy in the second half of the 17th century, during which time kings ruled without the restraint of representative institutions. This epoch is widely known as the age of Louis XIV because other European monarchs imitated and competed with developments Coming to power at a young age, Louis did not have the conventional humanist education of most princes, who learned Latin, ancient history, rhetoric, and the arts. Instead his instruction focused on the practical necessities of kingship, such as the history of France and its monarchy and After Louis XIV came to the throne just before his fifth birthday, the Italian-born first minister Cardinal Mazarin guided the policies and effectively instructed Louis in affairs of state both internal as well as foreign affairs.. When Mazarin died in 1661, Louis proclaimed that he would ...

Gas sensors on zinc oxide nanostructures

Gas sensors on zinc oxide nanostructures Introduction Gas sensors based on semiconducting metal oxides are being widely used for sensing gases and vapors. The initial momentum was provided by the findings of Seiyama et al. in metal oxide-gas reaction effects in 1962. It was shown that the electrical conductivity of ZnO can be changed by the presence of reactive gases in the air. The merits of these sensors include their reliability, low cost and easy implementation. Nanostructures of metal oxides have been found to be most effective as gas-sensing materials at elevated temperatures. Very popular sensing materials are metal oxide semiconductors such as ZnO, SnO2, TiO2, and WO3. Generally the change of electric field (conductance, voltage, resistance or the change of piezoelectric effect) of the sensor is monitored as a function of the target gas concentration. Gas sensors normally operate in air, in the presence of humidity and interfering gases. A heated substrate membrane is fitted with gas sensitive nanostructured semiconductor material which generates electrical output signals once chemical reactions are initiated at their surface. A common property of all these detection reactions is that they require significant levels of thermal activation to proceed at a measurable rate. Nanostructures of semiconducting oxides are widely used for gas sensing due to their large surface area to volume ratio and possibility of complete depletion of carriers within nanostructures when exposed to gases. Nitrogen dioxide (NO2) is a reddish-brown, highly reactive gas that reacts in the air to form corrosive nitric acid as well as toxic organic nitrates. The major man made source of NO2 emissions is high-temperature fuel combustion in motor vehicles and industries. These emissions are primarily in the form of NO which gets oxidized in the atmosphere to NO2. The conversion rate depends on the ambient concentration of NO and O3. If O3 is present, the conversion is very rapid. Health and safety guidelines suggest that humans should not be exposed to 3ppm or more NO2 gas for periods longer than eight hours because of its toxicity. NO2 is a pulmonary irritant primarily affecting the upper respiratory system in human beings. Continued or frequent exposure to high levels of NO2 can cause inflammation of the lungs. Therefore, the development of a stable NO2 gas sensor that can detect extremely low concentrations of NO2 with high sensitivity and selectivity is highly desirable. Such a sensor can be used for environmental monitoring. It can also be used in an early warning system that detects the presence of NO2 before the critical concentration of NO2 is reached. In our work, we will develop a sensor for NO2 gas sensing based on our understanding in sensor mechanism and synthesis of ZnO nanorods, using simple hydrothermal methods. The various performance parameters of the sensor, namely gas selectivity, sensitivity, response and recovery time will be studied. The gas sensor test-bench developed in COEN (Centre of Excellence in Nanotechnology), AIT, will be employed for characterizing the sensor performance. Chapter 2 Literature review This chapter is focused on the literature review of metal oxide based semiconducting nanostructures used for gas sensing. The working principle of metal oxide gas sensors, measurement methods and synthesis mechanisms is included in this review. Metal oxide nanostructures Metal oxides such as SnO2, WO3, TiO2 and ZnO possess high sensitivity to changes in their surrounding atmosphere at elevated temperatures. The sensing properties of metal oxides in form of thick or thin films have been studied to improve, by the addition of noble metals namely Pd, Pt, Au, Ag in terms of selectivity and stability. In 1991, Yamazoe showed that reduction of crystallite size caused a huge improvement in sensor performance. In a low grain size metal oxide almost all the carriers are trapped in surface states and only a few thermal activated carriers are available for conduction. From the point of view of device fabrication, first generation gas sensor devices were fabricated by thick film technology. Then the material fabrication processes improved towards the thin film technology. The fabrication process for thin film technology namely physical and chemical vapour deposition was highly automated and offers high reproducibility. The electrical properties of both thin and thick film sensors drift due to the grain porosity modification and grain boundary alteration. Several methods like addition of noble metals as catalysts or mixed oxides were put forward to improve the sensing performance of the gas sensors. The structural engineering of metal oxide nanostructured thin films proved to optimize the performance of these types of gas sensors. The various operating parameters such as response time, output signal, selectivity and stability can be improved and tuned through the optimization of the structure. Using structural engineering method, the various geometric parameters of metal oxide gas sensing matrix like grain size, agglomeration, film thickness, porosity can be controlled. The next forward step in gas sensing was achieved by the successful preparation of stable single crystal quasi-one-dimensional semiconducting oxides (nanorods, nanowires) leading to the third generation of metal oxide gas sensors. Working principle of metal oxide gas sensors Conductometric metal oxide gas sensors depend on changes of electrical conductivity due to the interaction with the surrounding atmosphere. The normal operating temperature of metal oxide gas sensors is within the range between 200  °C and 500  °C. The operating temperature should be high enough so that gas reactions occur in a time on the order of the desired response time and should also be low enough to avoid any variations in the bulk of the sensing matrix. The single crystal structure synthesized at temperatures higher than the operating temperature of the sensor shows high stability. Based on the study of a large range of oxides, the phenomenon of change in conductivity to the presence of reactive gases in air is common to oxides and not specific to a few special cases. If the conductivity is too high, then an effect is not expected and similarly if the conductivity is too low, then an effect will be difficult to measure. In practical applications, if an oxide sample has a resistivity between 104 and 108 Ocm at 300- 400  °C, then it will function as a gas sensor when heated to a temperature in this range. The sign of response (resistance increase or decrease) leads to a simple classification: gases can be classified as oxidizing or reducing and oxides can also be classified as p or n type. P-type oxides show a resistance increase in the presence of traces of reducing gases and resistance decrease to oxidizing gases. n-type oxides show opposite behaviour. This behaviour also correlates with the effect of changing oxygen partial pressure (PO2). Adsorption on surfaces The sensing mechanism in metal oxide gas sensors is related to ionosorption of species over their surfaces. The most important ionosorbed species when operating in ambient air are oxygen, water, carbon and its compounds. High concentrations of carbon can block surface sites of adsorption on a metal oxide. In the temperature range between 100  °C and 500  °C, oxygen ionosorbs over metal oxide in molecular (O2-) or atomic form (O-). Hence the study of adsorption is of fundamental importance in the field of sensors. Physisorption In this weakest form of adsorption like van der waals forces, no true chemical bond between the surface and adsorbate (or reaction species) is established. This bonding is mainly due to the induced dipole moment of a nonpolar adsorbate interacting with its own image charges on the polarized surface. The bonding energy is rather weak in the order of 0.1 eV. Chemisorption Chemisorption corresponds to the creation of chemical bonds between the adsorbate and surface and results in the electronic structure perturbation. In gas sensors, the target gas may be chemisorbed or physisorbed on the surface. When the gas species adsorb on the surface, molecules are either dissociated or diffused in the sensitive layer. Based on the Temperature Programmed Desorption (TPD) and Electron Paramagnetic study (EPR) studies, at lower operating temperatures, oxygen is considered to be adsorbed in molecular form (either as neutral O2 (ads) or charged O2(ads) 2- ) due to its lower activation energy. At higher temperatures it dissociates into atomic oxygen (either neutral O(ads) or singly ionized (charged) O(ads)- or doubly ionized O2(ads)- ). Finally at very high temperatures the loss of lattice oxygen (first surface and then bulk) takes place. When a reducing gas like CO comes into contact with the surface. These consume ionosorbed oxygen and in turn change the electrical conductance of metal oxide. The overall effect is a change of the density of ionosorbed oxygen that is detected as an increase of sensor conductance. Direct adsorption is also possible for the gaseous species like strongly electronegative NO2, which decreases the sensor conductance. NO2 absorption on tin oxide surfaces was studied by temperature programmed desorption measurements and found that the adsorbates originating from NO2 are the same as those from NO, as NO2 molecule dissociates easily over the tin oxide surface. These adsorbates can be divided into three types, two nitrosil types (Sn NO+ and Sn NO- ) and the nitrite type Sn O-N=O. The nitrite type does not play any role in gas sensing since it is not involved in any electron exchange with the bulk of the semiconductor. In practical applications, gas sensors are normally expected to operate in air, in the presence of humidity and interfering gases. In such cases, for operating temperatures in a range of 100 to 500  °C, at the surface of the sensitive material various oxygen, water and carbon dioxide related species are present. Some gas species form bonds by exchanging electrical charge with specific surface sites and others may form dipoles. Dipoles do not affect the concentration of free charge carriers and so they have no impact on the resistance of sensitive layer. Fig.1 explains the simplified case of adsorbed oxygen ions and hydroxyl groups bound to an n-type metal oxide semiconductor. These adsorbed ions cause a band bending while the dipoles change the electron affinity when compared to the state before the adsorption .The changes of the work function (?F) are determined by band bending (qVs due to ionosorption) and changes in the electron affinity () due to building of dipoles at the sur face (M d+ OH d-).

Static characteristics can be measured when all the transient effects of the output signal have stabilized in to steady state. Dynamic characteristics tend to describe the sensors transient behavior. Static characteristics Sensitivity Sensitivity is the ratio of incremental change in the output of the sensor to its incremental change of the measurand in input. For example, if we have a gas sensor whose output voltage increases by 1 V when the oxygen concentration increases by 1000 ppm, then the sensitivity would be 1 mV/ppm. Generally, the sensitivity to the target gas is defined as the percent reduction of sensor resistance. Sensitivity (%) = [(Ra- Rg) / Ra] Ãâ€"100, where Ra is the value of initial equilibrium resistance in air and Rg is resistance in the presence of a target gas. For convenience sometimes the sensitivity of gas sensor is expressed as the ratio of resistance in air over resistance in gas for reducing gases (Ra/Rg) and resistance in gas over resistance in air (Rg/Ra) for oxidizing gas. Selectivity The sensors ability to measure a single component in the presence of others is known as its selectivity. For example, an oxygen sensor that does not show a response to other gases such as CO, CO2 is considered to be selective. Selectivity = (sensitivity of gas1/sensitivity of gas2) Selectivity of the sensor is assessed by the ratio of sensitivity between the gases that is of interest to be detected over the gases that are uninteresting for detection in equivalent concentrations. To improve selectivity to specific gases, sensor array technology is also being adapted. Stability and Drift The sensors ability to produce the same output value when measuring a fixed input over a period of time is termed as stability. Drift is the gradual change in the sensors response characteristics while the input concentration of the gas remains constant. Drift is the undesired and unexpected change that is unrelated to the input. It may be attributed to aging, temperature instability, contamination, material degradation, etc. For instance, in a gas sensor, gradual change of temperature may change the baseline stability, or gradual diffusion of the electrodes metal into substrate may change the conductivity of a semiconductor gas sensor. Repeatability It denotes the sensors ability to produce the same response for successive measurements of the same input, when all operating and environmental conditions remain constant. Reproducibility The sensors ability to reproduce responses after some measurement condition has been changed. For example, after shutting down a sensing system and subsequently restarting it, a reproducible sensor will show the same response to the same measurand concentration as it did prior to being shut down. Hysteresis It is the difference between output readings for the same measurand, when approached while increasing from the minimum value and the other while decreasing from the peak value. Response Time The time taken by a sensor to arrive at a stable value is the response time. It is generally expressed as the time at which the output reaches a certain percentage (for instance 95%) of its final value, in response to a stepped change of the input. At the onset, the response time is very fast, followed by a long drawn tail before reaching steady state value, thus the response time are often expressed as 50% or 70% of the final time. Recovery time is defined as the time that the sensor takes to recover its resistance from exposed condition to the baseline value after target gas is cut out from the environment Dynamic Range or Span The range of input signals that will result in a meaningful output for the sensor is the dynamic range or span. All sensors are designed to perform over a specified range. Signals outside of this range may cause unacceptably large inaccuracies, and may even result in irreversible damage to the sensor. Dynamic characteristics The dynamic characteristics of a sensor represent the time response of the sensor system. The various important dynamic characteristics of sensors are discussed below, Rise time Rise time is defined as the time required by the sensor response to change from 10% to 90% of it final steady state value. Settling time It is the time taken by the sensor response to settle down to within a certain percentage of the steady state value. Influence of contact electrodes on sensor performance The contact electrodes used in gas sensors can have both electrical and electrochemical roles. For thin compact films, contact resistance plays an important role as dominant factor in overall resistance. The contribution of contact resistance is also extremely important for the case in which individual nanorods, nanowires or nanobelts are used as sensing layers. These electrodes are generally made of metals. They can also be fabricated from materials such as conductive polymers or conductive metal oxides. Although the concept of resistance change of the sensitive material when exposed to target gas is widely known, the overall resistance of the sensor depends not only on the gas sensing material properties but also on parameters such as transducer morphology, electrode etc. When the sensitive layer consists only of a compact continuous material and the thickness is larger than the Debye length, it can only partly depleted when exposed to target gas. In this case, the interaction does not influence the entire bulk of the material. Two levels of resistance are established in parallel and this fact limits the sensitivity. Thin layer will be the better choice which can be fully depleted. The representation shows the influence of electrode-sensing layer contacts. Rc is resistance of the electrode-metal oxide contact, R11 is the resistance of the depleted region of the compact layer, R1 is the equivalent of series resistance of R11 and Rc, and the equivalent series resistance of SRgi and Rc, in the porous and compact situations, respectively. Rgi is the average inter-grain resistance in the case of porous layer, Eb minimum of the conduction band in the bulk, qVs band bending associated with surface phenomena on the layer, and qVc also contains the band bending induced at the electrode-metal oxide contact. Improvement of selectivity by surface modifications Mixing metal oxides with Metals that function as catalysts Binary compounds and multi-component materials Doping are the most common methods used to enhance the gas sensing performance of metal oxide gas sensors. These additives can be used for modifying the catalytic activity of the base oxide, favoring formation of active phases and improving the electron exchange rate. The interaction of gas with the sensing material, resulting in the gas sensitivity, is determined by the chemical properties of the sensor surface. Different surface atoms can be introduced on the surface of the metal oxide sensors. This surface modification leads to new chemical reactivity and enables the sensor to be operated at low temperatures. Nanoscale particles of noble metals (Pd, Pt, Au and Rh) and oxides of other elements (Co, Cu and Fe) deposited on the surface of metal oxides can act as surface sites for adsorbates and promoters for surface catalysis. They create additional adsorption sites and surface electronic states and as a result gas sensitivity, selectivity, rate of response can be altered. For achieving high gas response, the noble metal should create optimal conditions for both electron and ion (spillover) exchange between surface and reacting gas species. The nature of noble metals, their oxidation state and their distribution on the surface are determining factors in gas sensor sensitivity and selectivity. To attain the homogenous distribution of noble metal on the surface is very difficult. Surface morphology has a significant effect on the shape and distribution of catalysts. Noble metal clusters have a tendency to accumulate at step edges and kinks of metal oxides during their deposition. Catalysts based on noble metals can be poisoned by many organic and inorganic chemicals that contain sulphur (H2S, SO2, thiols) and phophorus. The excessive thickness of catalytic active additives can change their functions, turning into either shunting layer or active membrane filters, obstructing the penetration of detecting gas in the surface of gas sensing matrix. At certain conditions this quality can also be used for an improvement of gas sensors selectivity. It has been studied that the incorporation of additional phases (different oxides) in nanocrystalline systems in small quantities can change the conditions of base oxide growth. SnO2 doped with Nb (0.1 4 mol%) causes a decrease in crystallite size from 220 nm for pure SnO2 to about 30 nm for Nb (0.1 mol%) doped samples. The additional influence observed due to doping is the change in film resistance. SnO2 doping by Nb and Sb in the range of 0.01 and 1.0 mol% during sol-gel preparation and annealed at 900  °C leads to film resistance decrease of 100 to 1000 times respectively, while doping with In resulted in a rise in film resistance by a factor of 100. The effect of doping on gas sensing properties of metal oxide gas sensors is different from the catalytic activity of these additives. Improvement of selectivity by operating conditions The sensor material may be operated at a comparably wide range of operating temperatures (300 900  °C) leading to different thermal energies for the surface reactions, differences may be attained by selecting the operating temperature, leading to a variation in gas sensitivity. A more improved version of this idea is to continuously increase or decrease the operating temperature of a given sensor and to continuously measure the variation of conductivity. This technique is known as temperature transient operation which gives more information in case of gas mixtures. To realize selective gas detection, sensor arrays are also constructed where several sensors showing different patterns of gas sensitivity are selected and simultaneously operated. A simple technique to obtain an array using one sensor is to modulate the operating temperature to different levels. Excessive increase of operating temperature may lead to a considerable drop of gas sensitivity. Moreover increasing working t emperature can create conditions, where gas response will then be determined by change of bulk properties of material. Improvement of response and recovery time of gas sensors A high speed gas switching system can be used to improve the response of the gas sensor. Yamazoe et al. studied the response and recovery properties of SnO2 porous film gas sensors using a high speed gas switching system. The developed system allows the rapid replacement of the gas atmosphere in the chamber between air and H2 (or CO). It was reported that the response speed of the sensor was fast, reaching a response time of less than 0.5s at 350  °C. The rates of diffusion and surface reactions of these gases (H2 and CO) in the porous sensing film are high enough for the sensor to reach a steady state within a short time. However the resistance in air did not reach the original value by repeated switching. This incomplete recovery was attributed to the slow desorption of H2O and CO2 formed on SnO2 by the surface reaction of H2 and CO respectively. Synthesis of 1-D metal oxide nanostructures Metal oxide nanostructures synthesis methods are broadly categorized as Solution phase synthesis method, where the growth process is carried out in liquid. Since aqueous solutions are used, this process is otherwise termed as hydrothermal growth process. Gas phase synthesis method uses gaseous environment in closed chambers. The synthesis is carried out at high temperatures from 500  °C to 1500  °C. Zinc oxide (ZnO) ZnO is wide bandgap (Eg = 3.4 eV) II VI compound semiconductor which has a non-centrosymmetric wurtzite structure with polar surfaces and lattice parameters a = 0.3296 and c = 0.52065 nm. The structure of ZnO can be described as a number of alternating planes composed of tetrahedrally coordinated O2- and Zn2+ ions, stacked alternatively along the c-axis. The tetrahedral coordination in ZnO results in piezoelectric and pyroelectric properties. The oppositely charged ions produce positively charged (0001)-Zn and negatively charged (000-1)-O polar surfaces, resulting in a normal dipole moment and spontaneous polarization along the c-axis. Hydrothermal Synthesis of Zinc oxide nanostructures Different techniques namely sol-gel, spray pyrolysis, hydrothermal method, electrospinning and thermal evaporation are prevalent for the synthesis of zinc oxide nanoparticles and nanorods. The hydrothermal process is an environmentally friendly process and does not require a complex vacuum environment. The hydrothermal process is surface independent and provides good control over the morphology of the nanostructures. ZnO nanorods growth on glass substrates by thermal decomposition of hexamethylenetetramine (HMT) and zinc nitrate is reported by Baruah et al. Thermal degradation of HMT releases hydroxyl ions which react with Zn2+ ions from ZnO. The role of HMT is to supply the hydroxyl ions to drive the precipitation reaction. Sugunan et al, have proposed that HMT being a long chain polymer and a nonpolar chelating agent, gets preferentially attached to the non polar facets of the zincitie crystal thereby cutting off the access of Zn2+ ions to them leaving only the polar (001) face for epitaxial growth. Metal oxide nanostructure based conductometric gas sensors Zinc oxide Characterization of gas sensing properties of ZnO nanowires is reported by Ahn et.al. ZnO nanowires were fabricated by a selective growth method on patterned Au catalysts forming a nanobridge between two Pt pillar electrodes. The gas sensing properties were demonstrated using NO2 gas. The response as a function of temperature is shown to be highest at 225  °C and linearly increased with the concentration of NO2 in the range of 0.5 3ppm and saturated beyond this range. The sensor performance is also compared with ZnO nanocrystals, Sn and In doped ZnO thin film. Also the nanobridge structure is shown to have fast recovery behaviour because the desorbed gas molecules can be easily removed off from the nanowires surfaces. Lupan et.al demonstrated the gas sensing behaviour of Al doped ZnO films synthesized by successive chemical deposition method. Successive chemical solution deposition method was reported to be simple and requires non-sophisticated equipment to produce nanostructures with high efficiency. Nanostructured ZnO films doped with Al showed a high sensitivity to CO2 than undoped ZnO films. Characterization and gas sensing properties of ZnO hollow spheres is reported by Zhang et.al. Different concentrations of NH3 and NO2 at different temperatures were used to test the gas sensor. ZnO hollow sphere sensor exhibited extremely different sensing behaviors to NH3 and NO2. The optimum operating temperature of the sensor was 200  °C for NH3 and 240  °C for NO2 respectively. The gas sensor exhibited much higher response to NO2 than to other gases at 240  °C implying good selectivity and potential application of the sensor for detecting NO2. Tin oxide Law et.al, analyzed room temperature sensing properties of a single crystalline tin oxide nanowire sensor towards nitrogen dioxide. NO2 chemisorb strongly on SnO2 surface and at room temperature desorption is not complete when the NO2 is removed. UV light was used to activate both the adsorption and desorption process. In the dark, oxygen adsorbs on the surface capturing electrons from the semiconductor and creates a depletion layer. When exposed to UV, photo-generated holes migrate to the surface and recombine with electrons releasing oxygen ions, with an increase in conductance. The detection limit was 2 10 ppm of nitrogen dioxide. Kolmakov et.al studied the effect of catalysis in tin oxide single wire FET structures. The sensing capabilities of SnO2 single nano-wires and nanobelts in a FET configuration before and after functionalization with Pd catalyst was analysed. The improvement in the sensing performance after catalysation was reported to be the combined effect of spill-over of atomic oxygen formed catalytically on Pd clusters and migrating on SnO2 surface and also to the back spill-over effect in which weakly bound molecular oxygen migrates to Pd clusters and are catalytically dissociated. Indium oxide Indium oxide nanowires have been tested towards ethanol by Xiangfeng et.al. A mixture of In2O3 nanowire and polyvinyl alcohol solution was coated on alumina tubes with two gold contacts at the end; a heating wire was inserted in the tube to operate in the temperature range 100 500 °C. The resistance of the nanowires was monitored in presence of air, ethanol and other gases. The highest response was obtained with ethanol, the detection limit was estimated to be equal to 100 ppm. Molybdenum oxide Molybdenum oxide nanorods based gas sensing was reported. The MoO3 nanorods were characterized by high response to ethanol and CO at temperatures in the range of 100  °C. The response of thin films with the same structure was comparatively studied and nanorods based sensor resulted in one order of magnitude more sensitive due to the high surface to volume ratio and reduced lateral dimensions of the nanorods. Other metal oxides Sawicka et.al. presented the nitrogen sensing properties of tungsten oxide nanowires prepared with electrospinning. The effect of processing parameter variations was studied and a comparison with thin films prepared by sol-gel was also presented. WO3 nanowires showed better NO2 sensing performances compared to sol-gel processed films due to increase in surface area of nanowires. A large amount of literature is available on the gas sensing properties of carbon nanotubes. Only little attention is put in the studies of gas sensing properties of metal oxide based tubular structures. Varghese et.al. studied the hydrogen sensing properties of titania nano-tubes. The tests were performed in nitrogen atmosphere and 1% H2. The response time increased with temperature and the response time was 2-3 min. NO2 gas sensors based on ZnO nanostructures Liu et.al reported the NO2 gas sensing properties of vertically aligned ZnO nanorod arrays prepared by hydrothermal method with zinc acetate and hexamethylenetetramine. The seed layer was deposited by ultrasonic spary pyrolysis. The aqueous hydrothermal solution was prepared by mixing equimolar ratio of zinc acetate dehydrate and HMT. The hydrothermal growth was carried out in a Teflon-lined stainless container. The substrate was put in the solution with the seeded face down and the container was sealed and kept at 110 °C for three hours. The nanorod sensor shows a higher sensitivity than the ZnO film based sensor prepared by ultrasonic spray pyrolysis. The enhanced sensitivity is attributed to the higher aspect ratio of the nanorod structure and the sensitivity increases with the length of the nanorod. The relative response of the sensor is linearly proportional to NO2 concentration in the 0.2 5 ppm range. The NO2 gas sensing properties of semiconducting type gas sensors with channels composed of non-agglomerated, necked ZnO nanoparticles were investigated by Jun et.al. The heat treatment of the nanoparticles at 400 °C led to their necking and coarsening. The slight necking of the nanoparticles with their neighbors also enhanced the conductivity of the channels, due to the lowering of the potential barrier. The response of the necked nanoparticle based sensor was reported to be as high as 100 when exposed to 0.2 ppm of NO2 at 200  °C. NO2 gas sensor based on ZnO nanorods grown by ultrasonic irradiation was reported to very high sensitivity with a very low detection limit of 10 ppb at 250 °C. Sonochemical route was employed for the fabrication of vertically aligned nanorods on a Pt electrode patterned alumina substrate. The total time requir

Intelligence Customers :: essays research papers

INTELLIGENCE CUSTOMERS The collapse of the Soviet Union has finally brought the cold war to a conclusion in the 1980’s. This collapse brought about a transfer in the global power structure. Threats such as terrorism, nuclear proliferation, narcotics trafficking and organized crime e became more prominent. The United States’ national security policies were revolutionized to be successful against the new risks towards the Nation. It may be assumed that the best group to handle the new pressures of the world would be the U.S. Intelligence Community, but the unique threats do not harbor the traditional roles that were designed for the U.S. Intelligence Community. Biological hazards such as Anthrax and Small pox, which are both remarkable threats to global and national security, have been collected, analyzed and dealt with by civilian government agencies and academic circles. The Intelligence Community should only use its technology to collect non-traditional intelligence that may infringe on only national and global security issues. There are hundreds of intelligence customers, but there are 14 primaries that come together for national security purposes.   Ã‚  Ã‚  Ã‚  Ã‚  To gain a better understanding of intelligence, the term must be defined. Intelligence is when data is collected, organized and becomes useful information. The information is then analyzed and becomes intelligence. The U.S. Intelligence Community supports the President of the United States, the cabinet, Congress, and down to the tactical level of deployed military forces. Each customer is equally as important as the other. The members of the Intelligence Community, also known as intelligence customers are comprised of 14 members: The Defense Intelligence Agency is a major producer and manager of foreign military intelligence. They provide military intelligence to warfighters, defense policymakers and force planners, the Department of Defense and the Intelligence Community in order to support U.S. military planning, operations, and weapon systems acquisition. The National Security Agency is the Nation's cryptologic organization. They coordinate, direct, and perform highly specialized activities to protect U.S. information systems and produce foreign intelligence information. The NSA is one of the most important centers of foreign language analysis and research within the Government. The Federal Bureau of Investigation is the principal investigative arm of the United States Department of Justice. The FBI is to uphold the law through the investigation of violations of federal criminal law; to protect the United States from foreign intelligence and terrorist activities; to provide leadership and law enforcement assistance to federal, state, local, and international agencies; and to perform these responsibilities in a manner that is responsive to the needs of the public and is faithful to the Constitution of the United States.

A Savage Journey

Numerous pursuits in obtaining dreams had been evident in the perceptions of many individuals.   How an individual carries himself in the realm of reality is actually dependent on how one tries to comprehend and internalize the explanations on why things consequently fall into place.As for Hunter Thompson, America has wickedly divulged on the rather comical state of rationality and thus is considerably out of track with regard to the rather important matters in life.   Its innovative response to technology and corruption is swallowing up the credit of the living masses and is thus benefited by the predator of the country.Thompson’s means of establishing what seemed to be true in his immediate time showed that the country was indeed facing a critical state of confusion over ‘reality’ and ‘idealism’.Undeniably, the impact of confusion towards a certain group of people or set of community may mean much on the development and the level of thinking of many.   How individuals are actually correlated in a broader sense, is the main reason why one action, either directly or indirectly, involves another whether it is in the negative or the positive state.AnalysisThompson’s book took pleasure upon unfolding the secrets of the past and the horrifying truths of the vortex of Las Vegas, or America at that.In the most extreme sense, I could easily distinguish the initial intent of the author in producing such masterpiece in the â€Å"dope world† which as a matte of fact, transcribed during the 60’s (Thompson), and if it may not be that harsh to take into assumption, inherited by today’s contemporary dopers, at that.One of the striking perceptions which I have noted on the novel, as established in Thompson’s plot, is the harshness of the society on the concept of ‘illegal’ entities.   Perhaps it is righteous enough to implement certain laws and reputation with regard to the matter, but th en again, the equilibrium of the imposition seems to boggle my sanity in that certain perspective.Thus, I realized that the callous form of justice had been crucially bias, taking for certain to a fact that even those who were held responsible for the eradication of what they introduced as ‘illegal’ were actually the catalysts of the inequity.   It takes to raise a brow in my rationality in the prudent side.The novel itself, taken with opinion based justification, is considerably a breakthrough to the society and to those who are well concerned over the matter.Perhaps ‘drugs’ is an evil commodity, but how Thompson was able to deliver his stands with the use of wickedly comical idioms and metaphors struck my amazement that his view on the society was amorously correlated and incorporated as rather the ‘evil’ one and ‘drugs’ as the hero of mankind (Thompson).   How’s that for the paradox of the universe?

Essay about The Early Life of Machiavelli

Essay about The Early Life of Machiavelli Essay about The Early Life of Machiavelli Slide 2: The early life of Machiavelli Machiavelli was born on May 3rd 1469 in Florence, Italy, the first son and third child of attorney Bernardo di Niccolà ² Machiavelli and his wife Bartolomea di Stefano Nelli. He was born to an established though not affluent middle-class family whose members had traditionally filled positions in local government. Machiavelli was born in a tumultuous era- popes waged acquisitive wars against Italian city-states, and people and cities might fall from power at any time. Married Marietta Corsini, 1501; children: five. Slide 3: About his life He was born as aristocrat†¦.This is a member of a aristocracy government. His father was an aristocrat. The most powerful class in Greek history While little of the author's early life has been documented, it is known that as a boy he learned Latin and that he quickly became an assiduous reader of the ancient classics. His main political experience in his youth was watching Savanarola from afar. Soon after Savanarola was executed, Machiavelli entered the Florentine government as a secretary. His position quickly rose, however, and was soon engaging in diplomatic missions. He met many of the important politicians of the day, such as the Pope and the King of France, but none had more impact on him than a prince of the Papal States, Cesare Borgia. Unfortunately, for Machiavelli, he was dismissed from office when the Medici came to rule Florence and the Republic was overthrown. The lack of a job forced him to switch to writing about politics instead of being active. His diplomatic missions were his last official government positions. Slide 4: Fields of work During the renaissance, he was an Italian diplomat, political philosopher, musician, poet, and playwright. He was a founder of modern political science, and more specifically political ethics. Machiavelli is regarded by some as the founder of value-free political science. He describes politics as it is, not as it might be, and shows how this knowledge can be exploited to bring greater order into human affairs. But Machiavelli's science is anything but value-free: He prefers glory to security, and admires innovators more than conservatives. Though he writes both for republics and tyrants, many have argued that he favors one over the other. In fact, he clearly has a preference for republics, but believes that the founding father of every republic needs to possess unrestrained power. Machiavelli engaged in a flurry of diplomatic activity on behalf of Florence, travelling to the major centers of Italy as well as to the royal court of France and to the imperial curia of Maximilian. We have letters, dispatches, and occasional writings that testify to his political assignments as well as to his acute talent for the analysis of personalities and institutions. During his lifetime, Machiavelli was best known as a playwright, and the Mandragola is his most original play. In this comedy Machiavelli applies his views to ordinary, seemingly nonpolitical life: Callimaco, a young man, is attracted to young Lucrezia, who is unfortunately married to Nicia, an older man. Thus Callimaco agrees to a plan devised by the Machiavellian figure Ligurio to gain access to Lucrezia. As this is a work of fiction, and not a long one to read, I will not reveal the whole plot here so as not to spoil anyone’s fun. The Mandragola is regarded as a classic of Italian literature, illustrating Machiavelli’s versatility as an author. It touches on many of the themes common to his political works: people’s ambition to get what they want, the gray areas in moral life, criticism of the church and so forth. But here his irreverent attitude is more visible than in his more â€Å"serious† works. Slide 5: Impacts Scholars have argued that Machiavelli was a major indirect and direct influence upon the political thinking of the Founding Fathers of the United States. Benjamin Franklin, James Madison and Thomas Jefferson followed

Femme Noir as the Queen of the Night Fantastical Transformations of a Woman

Femme Noir as the Queen of the Night Fantastical Transformations of a Woman Women played a crucial role in art and fashion in different periods of time. Some females were muses for artists and poets while others tried to break the rules established in society and introduce their own perspective of the world through their works of art. As such, it is necessary to see how women can contribute to the innovations and development of both art and fashion.Advertising We will write a custom article sample on Femme Noir as the Queen of the Night: Fantastical Transformations of a Woman specifically for you for only $16.05 $11/page Learn More A new creative project called ‘Art Meets Fashion’ is aimed at showing the benefit of using such exhibitions for educational and informational purposes. Experience gained by the participants of the project is sure to change their perception of the art and design as well as fashion in whole. The project consists of several teams each including an artist, a fashion designer, a representative of school, and a documenter. So, the team Femme Noir consists of an artist Duke Windsor, a fashion designer Osbaldo Ahumada, a documenter Susan Lazear, and a school representative Andrea Marx from SD Mesa College. The project Femme Noir was inspired with the image and the entire mood created by the Queen of the Night and her aria in The Magic Flute by Mozart. Fantastic and close-to-life elements can be found in the sculptures being a golden middle of the fashion and art meeting. Femme Noir is the name of the team that emerged from the image of a woman who knows how to survive in the world of the dark middle ages. So, the team members managed to apply the historic perspective and mood of the aria to the sculpture and painting in a fashionable manner using extravagant colors and irregular shapes. The exhibition of this team’s project will take place in Dolcetti Boutique to encourage the audience to join the world of fashion through art and vice versa.

Module 5 - Essay Example The number of visits made have a mean of 2.86 with a variance of 4.87. The standard deviation is 2.21 confirming the spread of the data. Group A has wide variations in terms of among the group observations. As Richmond, R (2006) puts it, the amount of variations in a group determine how the elements of the group are spread and how the differences amount to. The workers in group A are quite different from each other and it will not be a good idea to hire them due to this. Both groups have the same mean of 79.1 but the workers in group B have almost the same traits than in group A. When it comes to getting the services of a certain group, Group B is most likely due to its homogeneity. Group A has a standard deviation high above the expected of 24.12. In business, the mean is the best measure of central tendency. For example when you are reporting the sales you made in a day, the mean in the figure to use sine it shows what you have done in overall. On the other hand, while dealing in shares, the median is the most important as it shows the price which is the expectation of many. It shows where many people would like or got their shares in. In exports, the mode is the most important since it determines the frequency of doing business as well as the expected profit. Mode is also applicable when one is dealing with prediction of future business

The World is Spiky by Richard Florida Assignment

The World is Spiky by Richard Florida - Assignment Example They are spreading all over the globe and those countries that are able to access these advances are putting their mark on this globe. This is a phenomenon synonymous with modern world. He also asserts that education plays an important role in further flattening the ground and there is need to set the bar high for leaders as other players re overtaking. Evidently, the assertions put by Thomas are true. They are based on the current observation. However, there are details left out such as the progress of the technological leaders during the time others were catching up. Robert Florida puts forth that people with talent are being attracted to areas which are renowned for technological progress and output. The potential of the areas to attract talent from other parts is high because there is a concentration of financiers and appropriate education. This attraction has led to development of top areas or â€Å"spikes†. The areas where these talents are pulled from are low in progres s and productiveness.   The flattening effect notion arises because these areas are dispersing. Therefore, there is no denying that there are hills and valleys in the economy only that the distance between respective hills and valleys is being shortened by dispersion. The peaks are concentrated in Europe and the U.S and that signifies why more patents come from few recognized areas.Robert Florida is more salient because his presentations add an extra dimension which is disparity. Notably, he builds on what Thomas Friedman puts forward.

Writer's choice - Essay Example Women have for long suffered the effects of such atrocities since it is almost acceptable that they deserve the demeaning treat. You are then left to wonder what driving force must have marshaled such devastating thought (Quisar, Hameed & Aamar, 174-175). Much is already known that has been done to discriminate against the woman, however the question stays; that what is this that has consequentially led to such a looming crisis which unfortunately doesn’t seem to go soon? This leaves us with this inevitable task of crisscrossing the fundamentals amounting to gender biases. This underlying conception turns out to be a belief system set by the society. It is by the societal branding that women play such a demeaning role of subjects to all mannerisms. This in effect lowers their esteem which eventually makes them live in a sense of denial. It is kind of a bias that acts like an undue punishment that a negative yet lasting results. I may liken this to a classroom scenario that involves a teacher and a student. The teacher who keeps on giving negative remarks when the student answers a question, would make this student believe that they aren’t good enough to race on with the rest (Quisar, Hameed & Aamar 174). Few examples in real life situation back up this topic. One, it is evident that men play most leading roles in formal organizations and structures. In top management hierarchies, there is male domination on a global scale based on detailed observation of their profiles. The converse is unfortunately true that the female sex dominates the lower level ladders of such hierarchies. This overwhelming population at the lower ranks is to compensate for their biasness in the top hierarchy; which again gives a misconception of gender balance (Quisar, Hameed & Aamar 176). Unfortunately this undoing also is also reported in most of the cases in homes. Couples have yet more often confirmed that gender biasness and
