Helping the Private Sector to Achieve and Maintain Infrastructure Security

The infrastructure security has always been on the highest level for the US government. Still, the September 11, 2001 was the breaking point which is considered to be the start for heightened interest in critical infrastructure protection, both in public and in private sectors. To understand the main purpose of the research, it is crucial to check the main notions which are going to be considered, critical infrastructure in private sector.Advertising We will write a custom essay sample on Helping the Private Sector to Achieve and Maintain Infrastructure Security specifically for you for only $16.05 $11/page Learn More Critical infrastructure is the notion which identifies physical and computer-based systems, like telecommunications, banking, transportation, water and energy resources, etc. The private sector of the country’s economy is characterized by the organizations which are not controlled by the state, like private firms, companies, banks an d other private non-government organizations (Radvanovsky and McDougall 5). Thus, the main purpose of the research is to consider the main security strategies the private sector uses in the relation to the protection of critical infrastructures. The USA has a Department of Homeland Security which helps the private sector to cope with the problems it may face. Critical Infrastructure Protection Challenges for Private Sector There are a number of different challenges a private sector should cope with the purpose to organize critical infrastructure protection properly. There are a number of different normative laws which are aimed at analyzing those challenges and offering some decisions to solve them. Considering the challenges in addressing cybersecurity, the following key ones may be identified: the organizational stability should be achieved, the roles and capacities of the cybersecurity should be considered and the awareness should be increased, the efficient partnership with stak eholders should be considered, the information exchange should be on the high level (Powner 12). Private sector also faces other challenges, like securing control systems. One the one hand, technological innovations are involved in the sphere and allow specialists to control the process by means of different facilities. On the other hand, the specialized security technologies for control systems are not invented yet due to a number of reasons. Moreover, there are some ideas that securing control systems are not justified economically that create some problems. Finally, the security control systems may become the issue for conflicts on the basis of the priority notion (Dacey 18).Advertising Looking for essay on government? Let's see if we can help you!

National Infrastructure Protection Center is the organization that helps the private sector c ope with those challenges as the establishment of the correct information-sharing relations with the state is the first step for dealing with the problem. These challenges should be faced both by the private sector and by the Department of Homeland Security, even though it is the state institution, the security is going to be on the highest level in the private sector only when the government supports it. Introduction to Threat and Risk Analysis Models To conduct the critical infrastructure protection properly and on the highest level, the risk assessment in the sphere should be provided. Risk management and critical infrastructure protection in the private sector should be conducted on the basis of the assessment, integration, and management of such facilities as threats, vulnerabilities, and consequences. To conduct the risk assessment in the private sector, the following steps should be considered in this succession: The identification of the most critical infrastructures, Ident ification, evaluation and assessment of the threats, Consideration of the vulnerability of those critical assets, Specification of expected risks along with the expected consequences, The next stages should be followed to prioritize risk reduction activities. That is, the specialists should state and evaluate the ways aimed at reducing the risks which have already been highlighted and prioritize risk reduction by means of the risk reductions strategy. The private sector should collaborate with the government with the purpose to be aware of the innovations in the critical infrastructure protection field and to count on the state and its help. The role of the government in the security of the private sector is crucial. The Homeland Security Act of 2002 and other administration documents are directed at helping the private sector to cope with the threats and minimize the risks to minimum. Basic Principles for Critical Infrastructure Protection The fundamental principles for critical i nfrastructure protection may be based on the CARVER method. This method is based on six factors which influence the efficiency of the procedure. CARVER method is a military strategy which is used for identifying the targets for the attacks. It is reasonable to consider these principles for identifying the threats in the private sector directed at critical infrastructure.Advertising We will write a custom essay sample on Helping the Private Sector to Achieve and Maintain Infrastructure Security specifically for you for only $16.05 $11/page Learn More This method should be used to prioritize the targets which are considered to be the most vulnerable. Thus, the CARVER method is based on the following components, Criticality, Assessibility, Return, Vulnerability, Effect, and Recognizability. The main principle of this method is to identify the infrastructure with the highest value and to try to protect it by much attempt. The main idea of the criticality is to identify the target which plays crucial role in the achieving the goal and the elimination of which will put a private company much behind. The accessibility means that the company should consider whether the target easily reached or not. The critical infrastructure protection means high level of security and low level of accessibility. The company should check the return capacity of all the critical infrastructures and pay more attention to those which capacity to return is lower. The vulnerability of the target is really essential. The company should try to organize the work in such a way that all objects and targets which may be considered as vulnerable should be protected better. The effects should always be predicted. It is important for the private company to understand the outcomes of the threat in order to prevent those in case of any problems. It is also important to understand that the recognizability of the critical infrastructure is also essential. The private sector should protect its points with the purpose to reduce the risk for the target to be recognized by the competitor and either copied or destroyed (Pavlina n/p). Vulnerability Analysis Models Using the vulnerability analysis model, the company should follow the next steps to make sure that the competing agents are not going to reach the critical infrastructure and are not able to violate the company security. It may be concluded that the main purpose of the vulnerability analysis is to check and reduce the systems which may be available for natural and man-made damages. Thus, the steps one should follow to complete this method are: a) to identify the gaps and research needs in the sector, b) to check the competitors which may be suspected in organizing the attack, and c) to develop the strategies aimed at reducing the threat. The main purpose of this model is to encourage businessmen and entrepreneurs to protect their strategic objects better or, vice versa, to find faults in the criti cal infrastructure protection of the competitors and to use the information to combat them on the business arena (Catlin and Kautter 3).Advertising Looking for essay on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More Introduction to CI/KR Dependencies and Interdependencies The Department of Homeland Security has identified the Critical Infrastructure and Key Resources (CI/KR) which are protected by the government no matter whether public or private sector is involved in the affair. It is obvious that DHS cannot cope with all the CI/KR, so there are a number of other departments which help. To provide an effective protection of the CI/KR, the public and private sectors should establish good relationships based on the ideas and information exchanges, security planning with sharing the best practices, the coordinating structures should be perfectly established, the collaboration with the international community is important as well as the building of public awareness. The DHS identifies the following CI/KR: agriculture and food, commercial facilities, dams, energy, information technology, postal and shipping, banking and finance, communication, defense industrial base, transportation systems, chemi cal, critical manufacturing, emergency services, healthcare, nuclear reactions, materials and wastes, and water (â€Å"Critical Infrastructure and Key Resources†). If any of those CI/KR are involved into private sector, the company managers should care greatly of its security. Concepts of Continuity Of Operations (COOP) Plans and Continuity Of Government (COG) Continuity of operations is the notion which may be defined as a government effort to make sure that Primary Mission Essential Functions are going to work in spite of any incidents, including natural disasters, technological attacks and other accidents. The main purpose of COOP is to make the private sector, which deals with CI/KR, continue its work no matter what is happening in the country. The Continuity of Operations (COOP) Plan is a map for implementing the program designed by the Continuity Program (FEMA n/p). The Continuity of Government (COG) is defined as the necessity for the government and all its structures and operations to function without paying attention to any of the incidents which happen in the country. The main purpose of the COG is to provide the constitutional protection to the citizens of the country and the constitutional form of the government (FEMA n/p). In conclusion it should be stated that the proper functioning of the government is possible only in case if the private and public sectors work together and are able to collaborate with each others. It is crucial to understand that the critical infrastructure of the company should be properly protected. This means that the CARVER method should be applied to make sure that the cyber systems as well as other engineering systems are properly protected. The vulnerability analysis is really helpful for maintaining security in the critical infrastructure. The Continuity of Operations (COOP) and the Continuity of Government (COG) are the document which state that all systems and projects essential for the state should function, no matter what is happening in the country.

Free Essays on The Lover Of The Russian Queen

The Imperial Rapist and Lover-RASPUTIN Gregory Rasputin, who received practically little education, came from the rural Russia and achieved great recognition as a holy man in the highest circles of Russian society. Gregory Efimovich was born on January 10, 1869, in Prokovskoe, a small village in Siberia. As a young lad, Rasputin shocked his village by the fact he was developing into a rake, a man with a debauched, and endless, sexual appetite. It was soon thereafter that the debauched, lecherous peasant adopted the robes of a monk, developed his own self-gratifying doctrines, traveled the country as a â€Å"staretz† and sinned to his heart’s content. By the time he reached his early thirties, Rasputin had traveled to the Holy land and back. It was while in Kazan that the mysterious traveling monk made an impression among the local clergy. It was with the recommendations of these fooled priests that Rasputin headed to St. Petersburg for his first visit. While in the Russian capital, Rasputin’s presen ce attracted the attention of many of the country’s leading religious leaders. The staretz’ traveling tales, as well as the stories he told about his religious revival, seemed to capture the attention of the higher clergy of the Russian empire. The year was 1902.The Tsar’s death seemed imminent as his once strong body caved under the strain of his sickness. No one would have thought that Tsar Alexander III, a giant by most accounts, would be dead before his fiftieth year. And no one was more terrified by the events unfolding at the Imperial compound at Livadia, in the Crimea, as the young heir, Tsarevich Nicholas Alexandrovich. At the time of his father’s death in late 1894, Nicholas was an inexperienced youth wholly unprepared for the great task destiny had placed on his shoulders. Nicholas himself was terribly aware of this and upon his father’s death, the new Tsar consoled himself by asking God to give him the guidance...

Child Abuse Prevention and Treatment Research Paper

Child Abuse Prevention and Treatment - Research Paper Example There is a misplaced perception among the masses that child abuse is only sexual in nature. But emotional neglect of the child’s needs and desires by parents or guardians also constitutes child abuse. Childhood is very fragile and emotionally sensitive in nature. It is during this tender age that a child’s perspective and sense of self-worth is formed. Thus, child abuse can have detrimentally and long-lasting effects on the overall health of a child. Child abuse is more prevalent in developing and underdeveloped countries than the developed ones. In the face of grim poverty and starvation, children often become the innocent victims of multiple forms of abuse. In some countries, instances of child abuse are also driven by local myths and traditions. For example, in South Africa, it is believed that sexual intercourse with a virgin would cure a man of HIV.  The practice of child abuse has existed in some form or the other since time immemorial. It was a normal practice for early Greek and Roman civilizations to abandoned deformed or unwanted children, and to offer children as sacrifices to appease the gods. Similar practices were performed in Carthaginian, Roman, Greek, and Aztec societies. In Roman society, the father had absolute authority over his child's life. Sexual abuse of children was also common, but it was never perceived as being illegal or even immoral. It was rather a traditionally accepted phenomenon. But as humankind has progressed as a civilization, attitudes regarding child abuse have drastically changed and rightly so. Child abuse is now recognized as a grotesque social crime, one that can leave ugly scars on a child's life. Not only does it ruin the innocence of the child, but it also leads to psychological problems in adult life. Traditionally, child abuse has been categorized in the following ways- neglect, physical abuse, psychological/emotional abuse, and sexual abuse. Of the total reported cases of child abuse, neglect repr esented 54% of confirmed cases of child abuse, physical abuse 22%, sexual abuse 8%, emotional maltreatment 4%, and other forms of maltreatment 12% (National Committee to Prevent Child Abuse). Neglect can imply a situation where the parents fail to satisfy the basic needs of the child including physical, emotional and educational needs. Physical Abuse refers to any act of physical violence committed against a child. Psychological or emotional abuse denotes a pattern of behavior that impedes a child's psychological growth and development. This includes perennial criticism of the child, rejection and all other activities which would adversely affect a child's sense of self-worth. Sexual abuse, which has a rather hazy definition, involves any sexual act between an adult and a child. The more explicit form of sexual abuse occurs when a child is abused for the sexual gratification of an adult. The more subtle form of sexual abuse, though just as serious, is when "an adult indecently expos es their genitalia to a child, asks or pressures a child to engage in sexual activities, displays pornography to a child, or uses a child to produce child pornography." (Martin et al, 383). Studies have revealed that nearly 15% to 25% of women and 5% to 15% of men were sexually abused when they were children. (Kevin et al, 391).

What does an actor need to know about Bread and Puppet Theatre to Essay

What does an actor need to know about Bread and Puppet Theatre to produce and perform it - Essay Example The research is based on famous Bread and Puppet Theatre located in Glover in Northeast kingdom of Vermont, North America. The research gives an overview on principles and information an actor should know in order to produce and perform it."Theatre is as essential as Bread for daily Life"; "Theatre is a religion" are the principles on which exists the famous Obie Award winning Bread & Puppet Theatre founded in 1962 by Peter Schumann in New York City. Bread and Puppet theatre is one of the oldest, nonprofit and self supporting theatre companies in North America since 1960's.Bread and Puppet theatre, as the name suggests uses different arts in their shows like puppets (hand puppets and rod puppets), music, sculpture, dance etc. Bread and puppet is internationally recognized and renowned theatre group campaigning visually rich performance with slapstick, music and dance. Mostly all the performance of the group are done is streets or in farms or in large rooms (like churches). The partic ipants/actors onstage and offstage are mostly local volunteers. Internationally Bread and Puppet theatre performs massive spectacles with hundreds of participants devoted to social, political and environmental issues and sometimes of simple life issues.As the Bread and Puppet group believes in self dependency, The Company makes its own bread and patent of them is the distribution of self baked bread with "aioli" (garlic sauce) to the audience after every performance as a mean of creating community and from its central principle that "Art should be as basic to life as bread". The Bread and Puppet Group gained high visibility during early 60's and 70's during the time of Vietnam Wars for their Anti Vietnam War events. During the war times Bread and Puppet theatre staged processions involving hundreds of people. By the 80's the puppets had become emblematic of activist pacifism and a sine qua non of American Political theatre. All shows hosted by the group are antiwar, anti capitalism, anti globalization and pro Vermont independence. A brief background of the founder and the group will help a person to understand the foundations the theatre group is laid on. Peter Schumann, the founder of Bread and Puppet theatre was born in New York in 1934.Schumann studied and practiced dance and sculpture in Germany and in 1959 with a friend Dieter Starosky, he created dance group by the name "GRUPPE FUR NEUEN TANZ" (meaning New Dance Group). Schumann's work is not with formal or classical dance. He invented dance which was very different from traditional ballet and expressionist dance. Two years later, in 1961 with his wife Elka and two children he moved to the United States of America. He regularly attended lectures at Cunningham studio as he was heavily influenced by the radical innovations by John Cage and Merce Cunningham but very soon he separated himself from them. Peter was against the use of conventional form of dances ONLY, like Ballet which was a requirement for Cunningham. Cunningham refused to work with anybody who is not familiar with the Ballet form of dance. Peter Schumann-Founder of Bread & Puppet Theatre In 1970'sBread and puppet moved as theatre in residence to Goddard College where they practiced puppetry and exercised gardening and to make bread as a means of self dependency while living by the countryside. In 1974 the group moved into a 140years old hay farm in Glover, Vermont. The farm has a museum which is the resting place of many veteran puppets. Every year Bread and puppet group hosted Domestic Resurrection Circus which was a 2 day outdoor show which included skits highlighting many serious issues with a touch of humor. These Acts ranged from people dancing on Stilts to puppets lions dashing

Effect of Silver Nanoparticles on Plant Growth

Effect of Silver Nanoparticles on Plant Growth Nanoparticles are becoming increasingly used as materials in over 2000 consumer products due to their unique chemical, physical and electrical properties. A nanometer is one billionth of a meter and nanoparticles can be 1-100 nm in size. Silver nanoparticles are used for their antibacterial properties in many every day products such as food storage containers, air filtration systems and bandages. Nanomaterials are structures, devices, and systems at the nanometre scale. They are fast becoming an important material that can range from better and faster electronics to more efficient fuel usage, drug discovery and stronger, more resistant materials (Whatmore, 2006). The demand for engineered nanomaterials is a rapidly growing industry which was expected to reach a market size of approximately 2.6 trillion dollars by 2015 (Lee et al., 2010), however there is little knowledge on whether nanomaterials have an adverse effect on the environment or to human health and what the extent of these effects could be. Engineered nanoparticles have a wide range of chemical, physical and electrical properties such as conducting heat with low resistance and being stronger and lighter than other bulk materials (Tolaymat et al., 2017). The broad number of products that contain nanomaterials for consumers may lead to the release of an increased quantity of engineered nanoparticles in to the environment, which display different physiochemical properties than larger materials. (Geisler-Lee et al., 2012).  While the benefits of nanomaterials are broadcasted, their potential effects to the environment and to human health from their widespread use in consumer products are just becoming recognized. (Hoet et al., 2004). There are a number of ways that nanoparticles can be released in to the environment as shown in Figure 1. There are a number of different entry points for engineered nanomaterials into the environment, including wastewater treatment plant (WWTP) effluent, and WWTP sludge, however, it is difficult to estimate the relevant concentrations of nanoparticles that will be released in to the environment (Maurer-Jones et al., 2013). Once nanoparticles enter the environment there can be movement throughout the environment. One way this could happen is through food webs. If nanoparticles are consumed by organisms on a low trophic level thy may begin to accumulate in organisms at higher trophic levels. One of the challenges for working out the dangers associated with nanomaterial release in to the environment is the concern related to how clear our knowledge of how the properties of nanomaterials change once they interact with the environment. Also, nanoparticle properties can be affected by conditions, such as soil chemistry, pH, and organic matter. (Darlington et al., 2009) One of these effects to the environment could be the release of nanomaterials, through different pathways, in to bodies of water including lakes, rivers, and streams which could also cause run off in to soils and in to the air. Recent research (Das et al., 2012) showed that AgNPs rapidly but temporarily inhibited natural bacterioplankton production. Nanoparticles can affect biological behaviour at the cellular, subcellular and protein levels of a plant. The effect of nanomaterials on plant species is a topic that is being widely researched however there is still no conclusive answer on whether nanomaterials, specifically silver nanoparticles, have a negative impact on plant species, however metallic engineered nanoparticles may have stimulatory and inhibitory effects on plants. Arabidopsis thaliana is widely used in scientific research and was used in this study to further investigate the effects of silver nanoparticles on germination of seeds and also chlorophyll fluorescence after treatment with differing concentrations of nanomaterials. The silver nanoparticles used in this experiment were capped with PVP; this is because capped nanoparticles are less likely to aggregate in the solution over time and are more stable than uncapped nanoparticles (Tejamaya et al., 2012). Due to this a control of PVP had to be used to show that the capping had no effect on the plant species itself. Two mutations of A. thaliana seed were used in this experiment to test the effects of silver nanoparticles. The two sizes of silver nanoparticles were dissolved in distilled water which also meant that distilled water had to be used as a control to show that, on its own, it had no effect on the plant germination. Silver nitrate was also used at differing concentrations as a third control to show any differences between nanoparticles and as silver nitrates can be reduced, with PVP as a stabilizer, to synthesize silver nanoparticles (Samadi et al., 2010). As silver nanoparticles are smaller in size than silver nitrate particles, there will be a higher abundance of nanoparticles within the solution at a given concentration than silver nitrates. The effect of silver nanoparticles on plant species is important due to the many ways that nanoparticles can be dispersed in the environment. Relatively few studies have investigated the toxicological and environmental effects of engineered nanoparticles (Smita et al., 2012). However, the concentrations used in this experiment would generally be higher than the concentrations of these nanoparticles in the environment, although accurate concentrations in the environment are still not fully known. This is because their concentration in the environment will depend on factors such as the amount of the material released over time. The nanoparticles may become physically or chemically altered by environmental conditions such as temperature and salinity of water and also these factors may alter the form of the nanoparticles, exposure, and transport through the environment.   There is still concern over the potential impacts of engineered nanoparticles in the environment on aquatic and ter restrial organisms. Although some data indicates that current risks of engineered nanoparticles in the environment may be low, what we know of the potential impacts of engineered nanoparticles in the environment is still limited. There is still a demand for continued work to further understand the exposure levels for engineered nanoparticles in environmental systems and try and further our knowledge on the significance of these levels in terms of the environment which is what has been addressed in this project (Boxall et al., 2007). A similar study was carried out by (Obaid, 2016) which evaluated the impact of capped silver nanoparticles on terrestrial and aquatic plants, one of the terrestrial plants being A. thaliana . In this study chlorophyll fluorescence and gaseous exchange of the plants were measured to analyse the effects of the capped silver nanoparticles. The study showed that the capped silver nanoparticles displayed varying toxicity to the plants at higher concentrations, with particular interest to how they effected the germination of A. thaliana, with inhibition of germination at a concentration of 100mg/l of capped silver nanoparticles. The outcome of this study found that there are many factors that have significance on the toxicity of silver nanoparticles which includes exposure method, released ions, plant species, light intensity and growth mediums. However the concentrations used in the study by (Obaid, 2016),   much like the concentrations used in this project, are exaggerated and concentr ations as high as these will not be present in the environment as yet although it is important to test high concentrations due to large quantities of nanoparticles being used in every day products therefore such concentrations may be present in the environment in the very near future.

Capital Punishment Essay: Just Say No -- Argumentative Persuasive Topi

Capital Punishment: Just Say No      Ã‚  This essay will show that the United States is on an execution rampage. Since capital punishment was reinstated by the Supreme Court in the 1976 Gregg v. Georgia decision(Gregg), more than 525 men and women have been put to death by the state. More than 150 of these executions have taken place since 1996. 3,500 people are on death row today, awaiting their turn with the executioner. Capital punishment has existed throughout most of the course of our nation's history.    By the mid-1960s, however, public opposition to the death penalty had reached an all-time high, and the practice was banned by the Supreme Court in the 1972 Furman v. Georgia(Furman) decision. The Court held that state death penalty statutes were devoid of any standards, and that they therefore gave too much discretion to individual judges and juries to exact the ultimate punishment. Soon after the Furman decision, states began passing new laws that provided sentencing guidelines for juries. The Supreme Court was given another opportunity to address the issue of capital punishment in 1976, in Gregg v. Georgia, and it ruled that "the punishment of death does not invariably violate the Constitution." Since this ruling, capital punishment rates have grown exponentially in the United States.    In 1994, the Federal Death Penalty Act(Federal) authorized capital punishment for more than 60 offenses, including some crimes that do not involve murder. Moreover, the 1996 Anti- Terrorism and Effective Death Penalty Act created new barriers to effective federal review of constitutional claims in capital cases. Congress and many states have also slashed funding for most of the legal representation death row inmates forme... ... only two. Southern states, particularly Texas (443 death row inmates in 1999), hand down significantly more death sentences than those in the rest of the country. California, the state with the largest penal system, had 513 inmates on death row in the spring of 1999. Such state-to-state disparities exist because death penalty statutes are a patchwork of disparate standards, rules and practices and the consequence is the difference between life and death. Furthermore, some prosecutors are more zealous in seeking the death penalty than others - particularly if they are running for re-election.    WORKS CITED: Federal Death Penalty Act  Ã‚  Ã‚  Ã‚  Ã‚   http://www.deathpenaltyinfo.org/feddp.html Furman v Goergia  Ã‚  Ã‚  Ã‚  Ã‚   http://www.thinkquest.org/library/lib/site_sum_outside.html?tname=2760&url=2760/furman.htm Gregg v.

Six Sigma Applied to Warehouse Operation

A project Report on â€Å"DMAIC App to improve Warehouse Operation† Undertaken At xxxxxxxxxxxxxxx Warehouse In fulfilment of Capstone Project of Post Graduate Diploma in Industrial Engineering (PGDIE) By Rajul Agarwal (103) Puneet Jain (107) PGDIE- 41 Under the guidance of Dr. K. Maddulety Professor NITIE, Mumbai National Institute of Industrial Engineering, Mumbai-400087 Acknowledgement â€Å"Too often we are so preoccupied with the destination, we forget the guiding light† -anonymousI take this opportunity to extend my sincere thanks to HCCB, India for offering a unique platform to earn exposure and garner knowledge in the field of Warehousing Management. I wish to extend my sincere and heartfelt gratitude to my guide Mr. Sudhakar Nair, Warehouse Manager HCCB who guided, supported and encouraged me during the entire tenure of the project. I sincerely thanks to Dr K. Maddulety, my faculty guide, who has been guiding me throughout the project. 1. Executive SummaryThis p roject illustrates an approach to address the complexities faced by beverage industry by identifying critical supply chain activities which indirectly affect Customer Satisfaction. The solution is based on Six Sigma implementation through DMAIC Approach at these critical nodes. It has been established through various experiments that Customer Loyalty & Retention is very low in such industry; hence the customer satisfaction is directly affected by product unavailability. So the product availability is found to be a major concern here as it directly affects the customers buying decision.It is observed that in this industry, Product availability is majorly affected by the inconsistencies at the warehouse. This project particularly focuses on these warehousing processes which include the transportation of goods from plant to warehouse, then storing goods at warehouse and finally dispatching of goods to the customers. Based on this we have attempted to provide a blue print of possible ad vantages such as improved fill rates and better service levels. An empirical study was conducted at XYZ Beverage Company which produces carbonated soft drinks (CSD) and Non-Carbonated Beverages (NCB).Subsequently, its complete warehousing operation process was understood and DMAIC approach was used to improve the process dynamics. In the measure phase, using Process Capability Analysis it was found that the warehouse process doesn’t follow six sigma levels owing to the high level of damages/defectives and additionally there was a vast scope of improvement. Henceforth, Root cause analysis was done to identify the various causes of damages/defectives. The major causes identified here were lack of standardized operating procedures (SOP), over stacking & overloading.In the implementation phase, an action plan divided Phase wise, is proposed here so as to take into account variability caused by the two shifts in which the warehouse operates. A strict control needs to be followed s o as to maintain six sigma levels, for which p-chart type should be used in combination with proposed Warehouse Operation check list.

DMAIC Approach to Improve the Capability of SMT Solder Printing Process This paper implements the Define-Measure-Analyse-Improve-Control (DMAIC) approach to improve the capability of the solder paste printing process by reducing thickness variations from a nominal value. Process mapping and identifying key QCH are carried out in the â€Å"Define† phase here, while mean (x) and range R control charts followed by the estimates of process capability indices are adopted in the â€Å"Measure† phase.Then, the Taguchi method including L18 orthogonal array (OA), signal-to-noise (S/N) ratio, and analysis of variance (ANOVA) for S/N ratio is implemented in the â€Å"Analyse† phase. Taguchi’s two-step optimization is conducted in the â€Å"Improve phase. † Finally, the x and R control charts for solder thickness are used in the â€Å"Control† phase. This pa per was used to understand the DMAIC implementation process methodology followed by any process. The insights obtained were how Process capability analysis was carried out and furthermore how use of control charts be validated. . Applying Six Sigma Techniques in Plastic Injection Moulding Industry This paper presents an approach to implement a six sigma technique to decrease the scrap rate in a plastic injection molding plant. The primary tools used here are SIPOC, MSA, FMEA, P-Control Charts and Hypothesis Testing. In this case study we compare the average scrap rate for the â€Å"Before† study period with the average scrap rate of the â€Å"After† study period. This paper was used to understand the use of p-charts and how they can be applied in processes were defectives are being looked at.The insights obtained were effective use of FMEA and p-charts in such processes. 3. Introduction: HCCB operates a warehouse in Sewri. It caters to South and central Mumbai. It has a capacity of around 2000 Pallets or approximately 3-4 Lacs bottles (includes Recyclable Glass Bottles + pet bottles + can). It has around 35 mini trucks which daily carries around 38 thousand of bottles dispatched from the warehouse and deliver it to the different stockist/Retailers. The warehouse operates in two shifts every afternoon consignment comes from plant to the warehouse which is unloaded there and then stacked.Every morning at a specified place called floor the pallets are arranged inspected and then containers are loaded to the mini trucks which deliver it to the stockists/retailers. 4. Process Mapping: When a truck containing pallets of soft drinks is loaded at the plant it is fully inspected and then move towards the Warehouse * Once it is reached to the Warehouse, forklifts unload the pallets and then arrange it in the warehouse * FIFO is followed for outflow of goods Now the pallets are arranged at a floor where all the pallets are inspected * Simultaneously with in spection carriers (small trucks) keep on arranging inside the warehouse * During inspection if any damage is found then it is replaced by the same fresh item * After inspection the containers are loaded (Manually) to the carriers * While loading some bottles gets damaged that is also replaced by the fresh one and a count is kept for damaged goods * Once the loading is done the carriers move towards their destiny i. e. either to Stockist/retailers 5.

The Voice of Customer (VOC) is used to describe customer’s needs and their perceptions of product or service. The customer requirements from process and product are: * No damage/deformed item should reach to customer * If any damage is found then on the spot replacement * Customers don’t want to keep the track of damaged items which needs to be replaced next time when delivery van will come 4. Voice of Business: VOB is something which is critical from the perspective of stakeholders (WHse managers, Operators, All sorts of employees etc. ) in the business. * Improve profitability * Reduce cost * Least damages * Improve fill rate * Improve customer satisfaction 6. Measure Phase: 5. 1 Data to be measured: The following table shows the defective items noted in the month of October- November. From this data we calculated the defective proportion & defects per million opportunities. Defective Items| Total Items loaded| Defective proportion| DPMO| 145| 392732| 0. 000369209| 369. 2087| 55| 392700| 0. 000394703| 394. 7033| 132| 378243| 0. 000348982| 348. 982| 159| 332345| 0. 000478419| 478. 4185| 165| 402389| 0. 000410051| 410. 051| 145| 345673| 0. 000419472| 419. 4716| 123| 326789| 0. 00037639| 376. 3897| 190| 389023| 0. 000488403| 488. 403| 120| 334565| 0. 000358675| 358. 6747| 110| 324123| 0. 000339377| 339. 3773| 121| 306543| 0. 000394724| 394. 7244| 156| 402489| 0. 000387588| 387. 5882| 212| 437698| 0. 000484352| 484. 3522| 138| 290873| 0. 000474434| 474. 4339| 112| 238945| 0. 000468727| 468. 7271| 119| 367545| 0. 00032377| 323. 7699| 129| 263421| 0. 00048971| 489. 7104| 56| 463752| 0. 000336387| 336. 3867| 145| 375643| 0. 000386005| 386. 0 048| 123| 342356| 0. 000359275| 359. 2751| 90| 289532| 0. 000310846| 310. 8465| 225| 462163| 0. 000486841| 486. 8412| 121| 284532| 0. 00042526| 425. 2597| 175| 404512| 0. 00043262| 432. 62| 180| 403212| 0. 000446415| 446. 4153| 127| 329261| 0. 000385712| 385. 7122| 212| 431962| 0. 000490784| 490. 7839| 132| 337961| 0. 000390578| 390. 5776| 198| 326781| 0. 00060591| 605. 9104| 109| 392861| 0. 000277452| 277. 4518| 5. 2 Process Sigma Calculation: Average no. of items loaded each day = 360418 Average no. of defective items per day = 148Average defective proportion = 0. 000411328 Average DPMO = 411 Value of Sigma = 4. 9 Since the process sigma is 4. 9 which is less than 6. Now the next task is to analyse the process to find the scope of improvement. 5. 3 Statistical summary of â€Å"No. of defective items observed at various days† Observations: * Since P-value >0. 05 so the data passes the normality test * From the histogram it is visible that frequency distribution of defective data can be approximated to normal distribution * Since the data can be approximated as normally distributed we can apply process capability and SPC analysis . 4 Control Chart: Here in this case when the goods are inspected either they will be accepted to be shipped or simply discarded. So here we are not concerned with the no. of defects but concerned with the non-conformances (defectives). So the P-chart has been selected for SPC analysis:- Observations: * The above P-chart shows that all the observations lie inside the natural control limits. * It can be said that the process is under statistical control. * Since the process is under statistical control we can check for its capability. 7. Process Capability Analysis using MINITAB 15: * The desire is to minimise the damages to nil so the target valueis set to be zero. Observations: * Process sigma = 3. 34 * PPM Def = 410 which is lesser than 3. 4 ppm 7. Analysis Phase: 6. 1 Root Cause Analysis: 6 Implementation Phase: 7. 1 Propose d Action Plan: 7. 1. 1 Dividing the whole process of warehousing to deliver goods to the stockist/retailers into 4 stages: The process is divided into 4 stages on the basis of people& machines involved. In stage 1 goods are transported to the warehouse by one set of people (3 PL).Since warehouse operates in 2 shifts so when the trucks come from plant to warehouse that is unloaded by different set of people & in stage 3 â€Å"stacking at floor+ inspection + loading containers to carriers† are done by different set of people (working in 2nd shift). In stage 4 the goods transported from warehouse to stockists/retailers by different set of people and different carriers are involved. The purpose of dividing the whole process into 4 stages is to get more specific causes stage by stage and to get more insights.Since the different people and machines are involved in each stage so some specific plans may be put in place to reduce the damages. The following table shows the different ca uses and actions: Stage| Causes| Action Plan| 1| * In-Transit Damages * Bad Road Conditions * Mishandling by the operators| * Since in stage 1 the transportation is done by the 3PL so while selecting 3PL service provider company can bring some clauses in the agreement related to minimum breakage acceptable * Operators can be nstructed to follow the best route * Maintenance of carriers periodically after a specified time| 2| * Jerk in forklift * Over stacking * Improper training * Mishandling by the operators| * Establish SOP for the forklifts operation * Periodic maintenance of forklifts * Company currently uses diesel run forklifts that can be replaced by battery operated forkliftswhich require less maintenance * Provide incentives to the operators for achieving a certain level of damage free work * Provide ergonomically fithandles to the containers * Pet bottle packets as shown below gets unwrapped sometimes that needs proper packaging * Above kind of packaging can be either repla ced by carton (but that would not be a cost effective solution) or same packaging can be improved | 3| * Improper operation/jerk in forklift * Improper inspection * Mishandling | * Try not to rotate the people involved in inspection so that their learning curve makes them more efficient in that particular task * Provide incentive to the employees * Encourage employees | 4| * Overloading * Improper truck operation| * Avoid overloading * Proper training to the truck operators * Hire experienced operators * Provide incentives| | Environmental Causes * Rat Bite| * Especially tetra packed drinks are attacked by Rats * Use Rodent boxes to kill the rats * Daily check the rodent boxes & clean it if needed| 7. 1. 2 Major changes which can be brought in future to improve the overall process * SOP for forklift operations * Proper maintenance of forklifts and Trucks * Use of battery operated forklifts * Avoid overloading * Avoid over stacking 7 Control Phase: 8. 1 Identifying the Controlling El ements:The Critical-To-Quality Elements needs a proper control and inspection and hence the following Steps can be taken for the same: 1. Fork Lift Inspection Check Sheet: 2. Training Check List/ Regular Knowledge Tests 3. Rodent/ Insects Check List 4. Better Stacking Procedures a. Increasing the strength of the pallets from by increasing the cross pieces by 8 from 5 for the same 5cm x 10cm boards. b. In case of need to over stack during peak demand, we can keep the crates at a cross position so that the load gets distributed 8. 2 Failure Mode and Effect Analysis (FMEA): Use of FMEA tool for better analysis of damage reasons will help establishing a better control procedure. FMEA Flow Diagram 8. 3 Use Statistical Process Control (SPC) Charts:The case here is for graphing defectives for a varying sub group set. Hence use of p-chart should be used for continuous control. It will check when the variation is natural and when it needs correction. The following excel template can be used where directly data can be entered and the resulting p-chart will be generated. Excel template for Formulating p-chart 9. ESTIMATED BENEFITS OF PROJECT The biggest benefit of the project is in terms of reducing the risk of product unavailability downstream. The probability of defects can be drastically decreased and remain in specification limits. * 4-Stage Implementation phase for reducing defectives * Increased Sigma Levels approaching six sigma standards Increased Customer satisfaction and Product availability * Laid down Standard Operating Procedures (SOPs) for better warehouse operations control 10. CONCLUSION The reasons for the excessive defects are found. Over-stacking, Over-Loading & improper forklift operation were found out to be prime reasons using Cause and Effect Diagram. These were considered the CTQ’s for the warehousing operation. Project benefits were estimated and it is found that this improvement can bring the improvement in fill rate. 11.

The purpose of this lab activity was to measure anaerobic power per unit of time

The purpose of this lab activity was to measure anaerobic power per unit of time. This has to do with the muscular strength of the body and the rate the body utilizes ATP and the anaerobic glycolysis system. The Wingate test is performed by a warm up period of two to three minutes followed by a resting period of one to two minutes. Continuing the test after the resting period the performer peddles as fast as he/she can for five seconds. Then the resistance (calculated by performer's weight divided by 2.205 equaling performers Kilogram Weight multiplied by .075) is added and the peddling remains for 30 second at full speed while the data is taken. The data is taken by additional subjects counting the number of pedal rotations throughout the 30 seconds. This is how the power output is measured for the quadriceps muscles. The main point for the test is that the subject must remain at maximal speed for the entire 30 seconds. This test is useful for any type of athlete who is trying to improve muscle strength to maintain or gain speed and power. As one looks at the percentile charts of norms, he/she can evaluate his or herself among other athletes. This chart is useful because it is a starting point for training and improving the strength needed to endure and gain muscle strength. As compared with the percentile of norms the data calculated for me the performer, peak 5-second was 1023.55 which is average for a conditioned athlete. For Anaerobic capacity my percentage of 800.42001, which is exceptional by comparison to the percentile of norms, equals the power output of the muscle over the 30-seconds. Finally, the fatigue index which reflects the muscles ability to resist fatigue, which my percentage equaled 53.33, was at a low resistance to muscle fatigue. In conclusion to the results of the Wingate anaerobic test, I found out that this test is not exactly the preferred test of

Constructivism and Teaching English Assignment Example | Topics and Well Written Essays - 3000 words

Constructivism and Teaching English - Assignment Example Although constructivism might provide a model of knowing and learning that has important implications for classroom practices, it does not translate neatly into a set of pedagogical practices. The implementation of the constructivist approach is still worth discussion and clarification. This paper will highlight challenges associated with implementing constructivism in teaching English to speakers of other languages. Much writing has been done about theories of constructivism and the connection to superior learning results; however, there is no "consolidated" discussion of the foundations, results, and practical issues of constructivism. According to Marlowe and Page (1998), even when teachers recognise the value of and want to use constructivist approaches in their classrooms, their efforts often produce less than what they expected. There have been attempts to make constructivism operational so that classroom teachers can more rapidly apply constructivist theory to practice. The pr oblem is that the application of constructivism in classrooms is "neither widespread nor systematic". Constructivist propositions can seem fairly simple but hundreds of observations of and questions from pre-service and in ¬ service teachers over the past 10 years show that they are not. Teachers and administrators who already work with constructivist reform initiatives need guidelines to help with the implementation. Moreover, development of a constructivist view of learning as a basis for instruction implies fundamental changes.

French Revolution Essay Example | Topics and Well Written Essays - 5000 words

French Revolution - Essay Example The new order, or at least the aim of the new order, was the establishment of a peoples' republic where private property is owned by the feudal lord is berated, religion does not play any role in politics or in the lives of the people and a general will is represented by a group of bourgeois leftists. Although when the revolution ended, France was ruled by an emperor, Napoleon Bonaparte. If we look at 1789 France and try to determine the causes of the French Revolution, one fails to identify any decadence of its system. For instance, it was the largest, wealthiest and most powerful state in Western Europe. Its intellectuals led the Renaissance and then the Enlightenment era. French bourgeoisie was prosperous and well-established. Peasants owned and cultivated 40 percent of the land. What reason was there for a revolution Norman Gash (1989) quoting Napoleon's statement argues that the reason for French Revolution was nothing but vanity and that liberty was just a pretext. "One can see the argument. The aristocracy, only 2 per cent of the population, enjoyed a privileged position which their actual services to the state hardly seemed to justify. What the urban and professional middle classes clearly wanted was greater social recognition, easier access to rank and power and wider careers for their talents. Ambition and envy are impelling motives. (Gash, 1989) Lefebvre (1939) on the other hand asserts that the reason why French Revolution took place was the rise of the bourgeoisie presented by the Enlightenment philosophes as a better alternative to absolute monarchy. The philosophes of Europe appeared to have turned against the age of empires and monarchical rules supported largely by the clergy and the aristocracy. In bourgeoisie, the intellectual community invested lot of hopes perhaps for the reason that they opposed the aristocracy and offered an economy that was more egalitarian and involved for the first time in Europe's history the people. This paper will make an attempt to examine the question whether Rousseau's Concept of the "Social Contract" had a foremost influence on the intellectual development of the French Revolution and inspired its leaders. The paper will describe the salient concepts of Rousseau's Social Contract theory and enlist the events that took place during the ten years of the French Revolution (1789-1799). An attempt will be made to answer the question by studying the development of the Revolution and comparing that with Rousseau's social contract theory. It is important to note that the French Revolution was not influenced by Rousseau alone but it would not as well be completely out of place to assert that he wrote down the manual and the revolutionaries built the revolution by following his step-by-step instructions. In fact, Rousseau was one of the philosophes of Enlightenment which basically pushed the idea of liberalism based on virtue, reason, toleration and so on. Other philosophes
