Lucas-Phelps model - Essay Example Government’s interest in stabilising the economy is not only rooted on its political responsibility to control fluctuations in prices but equally to reign-in inflations that is brought about by temporary economic stressors as well. Ensuring the predictability of its economy will strengthen the job market and will also reinforce the collective confidence of the people to the government and its goals. Governments that are heavily involved in its country’s economic activity can, by its regular function, control interest rates that will restrict the liquidity of the market. By introducing temporary tax incentives however can create a situation that will lead to an excess supply of goods which circumstance will similarly bring down prices for that commodity. While enforcing stricter rules and regulation, the government can also influence the supply or the availability of goods in the market that will, in turn, force the prices of that commodity. These controls when implement ed on key economic indicator products such as oil or even wheat are effective tools in stabilising an economy. However, the end-results of these controls are not absolute due to the volatile nature of the economy. There are tangible variables that can be controlled through fiscal policies or through the degree in which laws are enforced but the collective consciousness of the market is very hard to control much less predict. The â€Å"rational expectation hypothesis† or â€Å"theory of rational expectation† posits that in uncertain conditions, the main players—composed of the people—in any economy make decisions based on their perceptions of how economic stressors will affect them (Muth, 1992). Meanwhile, economic agent’s rational expectations revolve around other market forces that would include government intervention, raw materials or input materials availability to create the best possible economic model for the future. Thus, the rational expec tation hypothesis propose that economic predictions based on the correlation of an infinite number of different variables are correct even if individual predictions made on the different variables turn out to be erroneous or inaccurate so long as the expected model holds. The primary reason why stabilisation policies are enforced or applied to a volatile market is to stabilise the economy, if not make it more predictable in order for economic agents to settle. However, if economic agents create an economic model base on the current economic values of economic stressors towards stabilising the economy, the introduction of a new variable from the government base on the â€Å"rational expectation hypothesis† will not make a huge impact. The primary reason for this is that over time, given that the economic agents also need to respond to the economic model they created the economy will eventually stabilise or settle. Cyclical Aggregate Demand Policy defines an economic systemâ₠¬â„¢s fluctuations as far as demands for goods are concerned. Counter cyclical or reversal of the economic system’s demand for goods to force it to follow a different path is not an absolute solution to stabilise prices in particular and stabilise the economy in general. This is especially accurate at full employment since the output of the work force will eventually find its way to mainstream market where its price is subject to market forces. The proposition that stabilisation policies are negated by rational expectati

Success of Product Repositioning Strategy for Class B Office Essay

Success of Product Repositioning Strategy for Class B Office Development in Moscow - Essay Example My company hired by a real estate investments fund, an owner of this property, received commercial contract to arrange marketing campaign and to sell these buildings as residential property. The reasoning behind this strategy is quite simple. On one hand, relatively small investors receive opportunity to invest into lucrative office property market in Moscow, which has 10-12% rate of return on investment compared to 5-6% that of residential property market. On the other hand, property developers receive so much desired cash significantly decreasing the whole property development cycle and improve their own rate of return on investment. The classical scheme (when office buildings are kept by developers to receive lease income or sold to strategic investors interested in regular income stream provided by lease payments) is modified with a new buy option for typical clients (lease holders) and completely a new option for residential property investors. Despite recent severe turbulence o n the equity markets and overall pessimistic attitude towards any long term investments our group managed to achieve remarkable results. The success of the strategy is proven by retail sale of a number of office buildings in Moscow. The purpose of this essay is to illustrate how theoretical strategic tools can be used in a real business situation to identify new business innovations and to assess how close the theory is to reality. The strategy theory undoubtedly provides useful tools for assessing current situation and identifying new opportunities. Elements of Five forces, basic supply – demand analyses, Value creation model, ERRC (Eliminate, Raise, Reduce, and Create) grid, reluctant customers and non-customers issues are theory tools used in the analysis. The analysis consists of macro and micro examination of the current commercial property industry situation in Moscow, and formulation of new opportunities in the office property sector of the industry based on the above analysis. The description of the real estate investment market in Russia In the situation of global market economic crisis, investors are becoming more risk averse and switching investment portfolios in favor of core assets like gold and real estate. Investments in property market in Russia in 2011 demonstrated 46% year on year growth with the highest volumes of 7 bn USD (See Exhibit 1 Investment volume dynamics), of which the commercial real estate sector accounts for about 95% (See Exhibit 1 Investment by sector). 2011 in Russia was remarkable by the rising number of foreign capital investments, which comprise around 45% of the total investment volume (See Exhibit Investment by investor origin). The reason for this is potentially high demand almost on all sorts of commercial property. Retail and office segments usually dominate the sector investments having 40% of total investment volume each (See Exhibit 1 Investment by sector). Moreover, the deal size increased in 2011: the numb er of deals exceeding 100 mn USD increased to 33% of total number of deals compared to 23% 2010. The market sector prime yields in Moscow stabilized at 9% in office and 11% in warehouse sectors in 2011 from the recent highs of 11.5% and 14.5% in 2009 (See 1 Exhibit Prime yield dynamics in Moscow) reaching pre crisis levels achieved by the market in 2007-2008. Historically, the office sector in Moscow has been the most attractive for

Criminal Offences And Felony Crimes Criminology Essay

Criminal Offences And Felony Crimes Criminology Essay In the court system we have many different types of crime, some ranging from something as simple as a speeding ticket, to crimes that are unthinkable. Each crime that we have also has a variety of sentencing and things that will happen when said crime is committed. FELONIES: A criminal offense punishable by death or by incarceration in a prison facility for at least one year. A felony is a serious crime; they include murder, rape, aggravated assault, robbery, burglary and arson. The federal government and many states have moved to a scheme of classifying the seriousness of felonies, using a number or letter designation. For purpose of criminal sentencing, for example, the federal system assigns a score of 43 to first degree murder, while a crime of theft is only rated a base offense level of 4. The persons history of crime is taken into consideration as well. Because of the differences among the states, crimes can be perceived differently. A felony in one state can be just a misdemeanor, and other areas it may not be a crime at all. In the United States a felony can lose certain rights: Loss of voting rights (which the Supreme Court interpreted to be permitted by the Fourteenth Amendment) Exclusion from obtaining certain licenses Exclusion from purchase and possession of firearms, ammunition and body armor Ineligibility for public office Ineligibility for serving on a jury Deportation (if the criminal is not a citizen) The consequences of committing a crime are serious; a felony conviction is at the very least one year in prison. But the terms of incarceration can vary a lot. U.S federal courts have sentencing guidelines, which suggest the period of imprisonment and fine for each offense. Courts can use these as standards but they are not required to use those guidelines to impose a sentence upon a convicted person. Wisconsin Felony Penalties: Class (A) felony: imprisonment for life: however, for a repeat offender, the term of imprisonment may increase up to 2 years to 6 years. (first degree intentional homicide, felony murder) Class (B) felony: up to 60 years, imprisonment may increase up to 2 to 6 years with a prior conviction. (Second degree intentional homicide, (manslaughter), first degree reckless homicide, conspiracy, first degree sexual assault, kidnapping) Class  © felony: the penalty is a fine of up to $100,000 or up to 40 years, or both, repeat offender 2 -6 years with a prior conviction. (felony drunk driving, 5th or subsequent offense, 2nd degree sexual assault, kidnapping, arson, robbery, vehicular manslaughter while intoxicated) Class (D) felony: $100,000 fine or up to 25 years or both. Prior convictions may increase from 2-6 years depending on it being a misdemeanor or felony.( Felony drunk driving, 5th or subsequent offense, felony vehicular homicide, vehicular homicide while intoxicated, child enticement, solicitation of a child) Class (E) felony: $50,000 fine 15 years or both, increase from 2-6 years for prior convictions. (battery, great bodily harm, burglary, robbery) Class (F) felony: $25,000 fine and up to 12-1/2 years in prison or both, repeat offender 2-6 years longer. (failure to act to prevent sexual assault of a child, sexual exploitation, burglary, stalking, theft) Class (G) felony: $25,000 fine and up to 10 years imprisonment or both longer for prior convictions 2-6 years (negligent homicide, negligent vehicular homicide, embezzlement, theft) Class (H) felony: up to $10,000 fine, and imprisonment up to 6 years or both longer for prior convictions 2-6 years (embezzlement, battery (great bodily harm), false imprisonment, stalking and theft) Class (I) felony: up to $10,000 fine and imprisonment up to 3-1/2 years or both, 2-6 years longer for prior convictions. (child pornography, embezzlement, battery- (substantial bodily harm) stalking, and theft) Misdemeanor: An offense punishable by incarceration, usually in a local confinement facility, for a period whose upper limit is prescribed by stature in a given jurisdiction, typically less than one year or less. Minor crimes consisting of offenses such as petty theft, which is the theft of items with little worth, normally a person cant be arrested for a misdemeanor unless the crime was committed in front of the officer. Misdemeanors are classified according to their severity. Each misdemeanor classification; provides recommendation for jail sentences and forfeitures (fines). A person convicted of a misdemeanor can be sent to a county or local jail, ordered to pay a fine, or both. Class (A) Misdemeanor: up to a $10,000 fine or prison for up to 9 months or both, repeat offenders may be in prison for up to 2 years. Class (B) Misdemeanor: up to a $1000 fine, 90 days in prison or both, repeat offender can increase time to up to 2 years. Class  © Misdemeanor: up to a $500 fine, and 30 days in prison or both, longer for repeat offender up to 2 years. Both felonies and misdemeanors are criminal charges but with one big difference, Felony you are in a state or federal prison, with a misdemeanor you are in a local or county jail. Offenses: A violation of the criminal law. Also, in some jurisdictions a minor crime, such as jaywalking, that is sometimes described as getting a ticket, others would include spitting on the sidewalk, littering, and traffic violations, including but not limited to not wearing a seatbelt. Another good word for it would be called an infraction, people that commit infractions are usually ticketed and released. Court appearances are usually waived, through payment of a small fine that can be mailed. Treason: A U.S citizens actions to help a foreign government overthrow, make war against, or seriously injure the United States, also the attempt to overthrow the government of the society of which you are a member. Special categories of crime do exist and they should be recognized, they are treason espionage, two crimes that are considered as the most serious felonies. In addition to being a federal offense its also a law under most states. Treason against the state shall consist only in levying war against it, adhering to its enemies, or giving them aid and comfort, and no person shall be convicted of treason except on the testimony of two witnesses to the same overt act or on confession in open court. Espionage: The gathering, transmitting, or losing of information related to the nation defense in such a manner that the information becomes available to enemies of the United States and may be used to their advantage. Espionage can be committed by noncitizens. Over at least 3 decades, beginning in the 1960s, Chinese spies apparently stole enough weapons-related information to advance Chinas nuclear weapons program into the modern era. An example of espionage is the crime committed by former FBI agent Robert Hanssen. In July 2001,he pleaded guilty in the U.S District Court in Alexandria, Virginia, to 15 counts of espionage and conspiracy against the United States He admitted to passing U.S secrets to Moscow from about 1970 until 2001, when undercover investigators caught him leaving a package for his Russian handlers under a wooden footbridge in a Virginia park. He had accepted more than $1.4 million dollars in cash and diamonds. In exchange for his FULL cooperation he was spared the death penalty and was sentenced to life in prison without the possibility of parole. Historically, treason also covered the murder of specific social superiors, such as the murder of husband by his wife (treason against the king was known as high treason and treason against a lesser superior was perit treason). Inchoate Crimes: Also called incomplete crimes, are acts which involve the inclination to commit, or indirect participation in, a criminal offense. They include, attempt, conspiracy, and solicitation. Being an accessory or an accomplice to a crime are also inchoate criminal offenses. They used to be considered a minor crime, but today many are considered serious crimes. This is a general rule about inchoate crimes: A person cannot be charged with an inchoate offense and the actual crime. Example: you cant be charged with both murder and attempted murder. The exception is conspiracy, you can be charged with drug trafficking and conspiracy to smuggle drugs. Lesser penalties are usually assigned for inchoate offenses, though the sentence for an inchoate crime may be equal to the penalties for the actual crime. To be convicted of an inchoate crime, the prosecutor must prove that you had a specific intent (mens rea) to commit or contribute to the crime. Inchoate crimes must involve some outward action or a substantial step in the completion of the crime. The person that actually commits the crime is known as the principal and others involved are known as the accomplices. If you commit a bank robbery, and you drive the car, you are just as guilty as the person holding the gun to the bank tellers head. Witnessing a murder and not calling it in, makes you just as guilty as if you committed the murder yourself. Inchoate crimes are highly controversial and often challenging to litigate.

Analysis of COVERGIRLâ„¢ Advertisement Essay -- Advertising, Blond

Introduction I have examined and analyzed the COVERGIRLâ„ ¢ NatureLuxe advertisement that uses common feminine stereotypes. In this advertisement, COVERGIRLâ„ ¢, which runs in Seventeen magazines, targets women through their choices of colors, fonts, and images used. Certain stereotypes are used; such as, those who are more feminine tend to prefer lighter, happier colors, such as pink. Also, the use of a celebrity, who many young women look to as an icon, assists in the advertisement of the COVERGIRLâ„ ¢ product. COVERGIRLâ„ ¢, more than likely, is able to successfully market their lip-gloss product in the United States by using common gender stereotypes to show femininity and how those, mainly women, should be presented in today’s society. Target Audience This advertisement appears in the Seventeen magazines, whose readers range in age between thirteen and twenty-five. The visual shows a young, blonde, Caucasian female who is attracting the readers to the COVERGIRLâ„ ¢ product. Placing this sort of ad in the Seventeen magazines is appealing to most young women due to the beautiful celebrity, Taylor Swift, who uses the same product. Also, the colors used, such as the pastel pinks, draws in the reader since they are very feminine colors. Finally, the product itself is appealing to the audience of Seventeen because younger women like to look their best, and to do that, lip-gloss is a handy accessory. Layout There are several aspects to the layout of this advertisement. Women, regardless of age, tend to be drawn to the use of beautiful, younger women in an arrangement, which makes this design effective. Firstly, Taylor Swift (the young woman in the picture) has been properly dressed so that the lip-gloss she is using matc... ...e lip-gloss product. By using this advertisement to examine common womanlike stereotypes, and to see what women are drawn to in the United States, we notice that choices of colors, fonts, and images used can be appealing to those who are more feminine. The details presented to each reader of this magazine advertisement are shown a multitude of feminine stereotypes, which are targeted towards younger women in America.

Concept of data mining and warehouse

Abstraction: Data excavation can detect information hidden within valuable informations assets. Knowledge find, utilizing advanced information engineerings, can bring out venas of surprising, aureate penetrations in a mountain of factual informations. Data excavation consists of panoply of powerful tools which are intuitive, easy to explicate, apprehensible, and simple to utilize. These advanced information engineerings include unreal intelligence methods ( e.g. adept systems, fuzzed logic, etc. ) , determination trees, regulation initiation methods, familial algorithms and familial scheduling, nervous webs ( e.g. back extension, associate memories, etc. ) , and constellating techniques. The synergism created between informations warehousing and informations excavation allows cognition searchers to leverage their monolithic informations assets, therefore bettering the quality and effectivity of their determinations. The turning demands for informations excavation and real-time analys is of information will be a impulsive force in the development of new informations warehouse architectures and methods and, conversely, the development of new informations excavation methods and applications. Keywords: Computer package, Data excavation, Data structuring, Knowledge-based systemsIntroductionData excavation is concerned with detecting new, meaningful information, so that determination shapers can larn every bit much as they can from their valuable informations assets. Using advanced information engineerings, cognition find in databases, can bring out venas of surprising and aureate penetrations in a mountain of factual informations. Data repositing is a methodological analysis that combines and co-ordinates many sets of diversified informations into a incorporate and consistent organic structure of utile information. In larger organisations, many different types of users with varied demands must use the same monolithic informations warehouse to recover those pieces of information which best suit their alone demands.DATA Mining CONCEPTSData excavation can be defined as the procedure of researching and analysing big volumes of informations in order to detect interesting and co ncealed forms, regulations and relationships with informations. The intent of informations excavation is to let a corporation to better its selling, gross revenues and client support operations through better apprehension of its clients. Large corporation are utilizing informations excavation to turn up high-value clients, to heighten their merchandise offerings to increase gross revenues and to minimise losingss due to error or fraud.HOW DATA MINING WORKSData excavation is a constituent of a wider procedure called â€Å" cognition find from database † . It involves scientists and statisticians, every bit good as those working in other Fieldss such as machine acquisition, unreal intelligence, information retrieval and pattern acknowledgment. Before a information set can be mined, it foremost has to be â€Å" cleaned † . This cleansing procedure removes mistakes, ensures consistence and takes losing values into history. Next, computing machine algorithms are used to â€Å" mine † the clean informations looking for unusual forms. Finally, the forms are interpreted to bring forth new cognition. How informations excavation can help bankers in heightening their concerns is illustrated in this illustration. Records include information such as age, sex, matrimonial position, business, figure of kids, and etc. of the bank ‘s clients over the old ages are used in the excavation procedure. First, an algorithm is used to place features that distinguish clients who took out a peculiar sort of loan from those who did non. Finally, it develops â€Å" regulations † by which it can place clients who are likely to be good campaigners for such a loan. These regulations are so used to place such clients on the balance of the database. Next, another algorithm is used to screen the database into bunch or groups of people with many similar properties, with the hope that these might uncover interesting and unusual forms. Finally, the forms revealed by these bunchs are so interpreted by the information mineworkers, in coaction with bank forcesDATA WAREHOUSE CONCEPTSData repositing is a subject-oriented, integrated, historical and summarized informations in support of direction ‘s determination devising.Capable orientedIt shops subject-oriented information such as clients, merchandises and pupils instead than the application countries such as client invoicing, stock list and pupil direction.IntegratedIt is the consolidation and integrating of corporate application-oriented informations from multiple beginnings. The integrated informations beginning must be made consistent to show a incorporate position of the informations to the users.HistoricalData warehouse informations is historical. It represents snapshots overtime. Data is read merely because it is historical informations.SummarizedA information repositing system can frequently be summarized to an appropriate degree of item. A information warehouse provides information to help companies in determination devising. Companies can utilize the valuable information in a information warehouse to place tendencies. A information repositing is a procedure that can:Retrieve information from the beginning systemsTransform informations into a utile format to put into the informations warehousePull off the databaseUse tools for edifice and pull offing the information warehouseDATA Mining TOOLSOrganizations that wish to utilize informations excavation tools can buy excavation plans designed for bing package and hardware platforms, which can be integrated into new merchandises and systems as they are brought online, or they can construct their ain usage excavation solution. For case, feeding the end product of a information excavation exercising into another computing machine system, such as a nervous web, is rather common and can give the mined informations more value. This is because the informations excavation tool g athers the informations, while the 2nd plan ( e.g. , the nervous web ) makes determinations based on the information collected. Different types of informations excavation tools are available in the market place, each with their ain strengths and failings. Internal hearers need to be cognizant of the different sorts of informations excavation tools available and urge the purchase of a tool that matches the organisation ‘s current detective demands. This should be considered every bit early as possible in the undertaking ‘s lifecycle, possibly even in the feasibleness survey. Most informations excavation tools can be classified into one of three classs: traditional informations excavation tools, splashboards, and text-mining tools. Below is a description of each.Traditional Data Mining Tools. Traditional information excavation plans help companies set up informations forms and tendencies by utilizing a figure of complex algorithms and techniques. Some of these tools are installed on the desktop to supervise the information and high spot tendencies and others capture information residing outside a database. The bulk are available in both Windows and UNIX versions, although some specialize in one operating system merely. In add-on, while some may concentrate on one database type, most will be able to manage any informations utilizing on-line analytical processing or a similar engineering.Splashboards. Installed in computing machines to supervise information in a database, splashboards reflect informations alterations and updates onscreen – frequently in the signifier of a chart or table – enabling the user to see how the concern is executing. Historical informations besides can be referenced, enabling the user to see where things have changed ( e.g. , addition in gross revenues from the same period last twelvemonth ) . This functionality makes splashboards easy to utilize and peculiarly appealing to directors who wish to hold an overview of the company ‘s public presentation.Text-mining Tools. The 3rd type of informations mining tool sometimes is called a text-mining tool because of its ability to mine informations from different sorts of text – from Microsoft Word and Acrobat PDF paperss to simple text files, for illustration. These tools scan content and change over the selected information into a format that is compatible with the tool ‘s database, therefore supplying users with an easy and convenient manner of accessing informations without the demand to open different applications. Scanned content can be unstructured ( i.e. , information is scattered about indiscriminately across the papers, including electronic mails, Internet pages, sound and picture informations ) or structured ( i.e. , the information ‘s signifier and intent is known, such as content found in a database ) . Capturing these inputs can supply organisations with a wealth of information that can be mined to detect tendencies, constructs, and attitudes.Besides these tools, other applications and plans may be used for informations excavation intents. For case, audit question tools can be used to foreground fraud, information anomalousnesss, and forms. In add-on, internal hearers can utilize spreadsheets to set about simple informations excavation exercisings or to bring forth drumhead tabular arraies. Some of the desktop, notebook, and server computing machines that run runing systems such as Windows, Linux, and Macintosh can be imported straight into Microsoft Excel. Using polar tabular arraies in the s preadsheet, hearers can reexamine complex informations in a simplified format and bore down where necessary to happen the underlining premises or information. When measuring informations excavation schemes, companies may make up one's mind to get several tools for specific intents, instead than buying one tool that meets all demands. Although geting several tools is non a mainstream attack, a company may take to make so if, for illustration, it installs a splashboard to maintain directors informed on concern affairs, a full data-mining suite to gaining control and construct informations for its selling and gross revenues weaponries, and an question tool so hearers can place fraud activity.DATAMINING TechniqueIn add-on to utilizing a peculiar information excavation tool, internal hearers can take from a assortment of informations mining techniques. The most normally used techniques include unreal nervous webs, determination trees, and the nearest-neighbor method. Each of these techniques analyzes informations in different ways:Artificial nervous webs are non-linear, prognostic theoretical accounts that learn through preparation. Although th ey are powerful prognostic mold techniques, some of the power comes at the disbursal of easiness of usage and deployment. One country where hearers can easy utilize them is when reexamining records to place fraud and fraud-like actions. Because of their complexness, they are better employed in state of affairss where they can be used and reused, such as reexamining recognition card minutess every month to look into for anomalousnesss.Decision trees are arboreal constructions that represent determination sets. These determinations generate regulations, which so are used to sort informations. Decision trees are the favorite technique for constructing apprehensible theoretical accounts. Hearers can utilize them to measure, for illustration, whether the organisation is utilizing an appropriate cost-efficient selling scheme that is based on the assigned value of the client, such as net income.The nearest-neighbor method classifies dataset records based on similar informations in a histor ical dataset. Hearers can utilize this attack to specify a papers that is interesting to them and inquire the system to seek for similar points.Each of these attacks brings different advantages and disadvantages that need to be considered prior to their usage. Nervous webs, which are hard to implement, necessitate all input and end point end product to be expressed numerically, therefore necessitating some kind of reading depending on the nature of the data-mining exercising. The determination tree technique is the most normally used methodological analysis, because it is simple and straightforward to implement. Finally, the nearest-neighbor method relies more on associating similar points and, hence, works better for extrapolation instead than prognostic questions. A good manner to use advanced informations excavation techniques is to hold a flexible and synergistic informations excavation tool that is to the full integrated with a database or informations warehouse. Using a tool that operates outside of the database or informations warehouse is non as efficient. Using such a tool will affect excess stairss to pull out, import, and analyze the information. When a information excavation tool is integrated with the informations warehouse, it simplifies the application and execution of excavation consequences. Furthermore, as the warehouse grows with new determinations and consequences, the organisation can mine best patterns continually and use them to future determinations. Regardless of the technique used, the existent value behind informations excavation is patterning – the procedure of constructing a theoretical account based on user-specified standards from already captured informations. Once a theoretical account is built, it can be used in similar state of affairss where an reply is non known. For illustration, an organisation looking to get new clients can make a theoretical account of its ideal client that is based on bing informations captured from people who antecedently purchased the merchandise. The theoretical account so is used to question informations on prospective clients to see if they match the profile. Modeling besides can be used in audit sections to foretell the figure of hearers required to set about an audit program based on old efforts and similar work.BENEFITS OF DATA MINING & A ; DATA WAREHOUSE TO ORGANIZATIONSBenefits of Data MiningOrganizations ‘ point of positionData excavation is really of import to concerns b ecause it helps to heighten their overall operations and detect new forms that may let companies gives better function to their clients. Through informations excavation, fiscal and insurance companies are able to observe forms of deceitful recognition card use, place behavior forms of hazard clients, and analyze claims.Besides that, informations excavation besides help these companies minimize their hazard and increase their net incomes. Since companies are able to minimise their hazard, they may be able to bear down the clients lower involvement rate or lower premium. Companies are stating that information excavation is good to everyone because some of the benefit that they obtained through informations excavation will be passed on to the consumers. Data excavation allows marketing companies to aim their clients more efficaciously, hence, can cut down their demands for mass advertizements. As a consequence, the companies can go through on their economy to the consumers. Harmonizing to Michael Turner, an executive manager of a Directing Marking Association † Detailed consumer information lets apparel retail merchants market their merchandises to consumers with more preciseness. But if privateness regulations impose limitations and barriers to informations aggregation, those restrictions could increase the monetary values consumers pay when they buy from catalog or on-line dress retail merchants by 3.5 % to 11 % † . When it comes to privacy issues, organisations will state that they are making everything they can to protect their clients ‘ personal information. In add-on, they merely use consumer informations for ethical intents such as selling, observing recognition card fraudulent, and etc. To guarantee that personal information are used in an ethical manner, the main information officers ( CIO ) Magazine has put together a list of what they call the Six Commandments of Ethical Date Management. The six commandments include: â€Å" 1 ) information is a valuable corporate plus and should be managed as such, like hard currency, installations or any other corporate plus ; 2 ) the CIO is steward of corporate informations and is responsible for pull offing it over its life rhythm ( from its coevals to its appropriate devastation ) ; 3 ) the CIO is responsible for commanding entree to and usage of informations, as determined by governmental ordinance and corporate policy ; 4 ) the CIO is respo nsible for forestalling inappropriate devastation of informations ; 5 ) the CIO is responsible for conveying technological cognition to the development of informations direction patterns and policies ; 6 ) the CIO should spouse with executive equals to develop and put to death the organisation ‘s informations direction policies. † Since informations excavation is non a perfect procedure, errors such as mismatching information will happen. Companies and organisations are cognizant of this issue and seek to cover it. Harmonizing to Agrawal, an IBM ‘s research worker, informations obtained through excavation is merely associated with a 5 to 10 per centum loss in truth. However, with uninterrupted betterment in informations excavation techniques, the per centum in inaccuracy will diminish significantly.Benefits of Data WarehouseThere are a big figure of obvious advantages involved with utilizing a information warehouse. As the name suggests, a information warehouse is a computerized warehouse in which information is stored. The organisation that owns this information can analyse it in order to happen historical forms or connexions that can let them to do of import concern determinations. In this article I will travel over some of the advantages and disadvantages that are connected to informations warehouses. One of the best advantages to utilizing a information warehouse is that users will be able to entree a big sum of information. This information can be used to work out a big figure of jobs, and it can besides be used to increase the net incomes of a company. Not merely are users able to hold entree to a big sum of information, but this information is besides consistent. It is relevant and organized in an efficient mode. While it will help a company in increasing its net incomes, the cost of calculating will greatly be reduced. One powerful characteristic of information warehouses is that informations from different locations can be combined in one location. There are a figure of grounds why this is of import. When information is taken from multiple beginnings and placed in a centralised location, an organisation can analyse it in a manner that may let them to come up with different solutions than they would if they looked at the information individually. Data excavation is connected to informations warehouses, and nervous webs or computing machine algorithms are responsible. When information is analyzed from multiple beginnings, forms and connexions can be discovered which would non be found otherwise. Another advantage of information warehouses is that they can make a construction which will let alterations within the stored informations to be transferred back to operational systems. However there are a figure of disadvantages that need to be mentioned every bit good. Before informations can be stored within the warehouse, it must be cleaned, loaded, or extracted. This is a procedure that can take a long period of clip. There may besides be issues with compatibility. For illustration, a new dealing system may non work with systems that are already being used. Users who will be working with the informations warehouse must be trained to utilize it. If they are non trained decently, they may take non to work within the informations warehouse. If the informations warehouse can be accessed via the cyberspace, this could take to a big figure of security jobs. Another job with the informations warehouse is that it is hard to keep. Any organisation that is sing utilizing a information warehouse must make up one's mind if the benefits outweigh the costs. Once you have paid for the information warehouse, you will still necessitate to pay for the cost of care over clip. The costs involved with this must ever be taken into consideration. When it comes to hive awaying information, there are two techniques which are used. The first is called the dimensional technique. When the dimensional technique is used, information will be stored within the informations warehouse as facts. These facts will take the signifier of either text or numerical information. Data which is stored with the dimensional technique will incorporate information which is specific to one event. The dimensional technique is utile for workers who have a limited sum of information engineering accomplishments. It makes the informations easy for them to analyze and understand. In add-on to this, information warehouses that use the dimensional technique tend to run rapidly. The biggest job with the dimensional technique is if the company decides to alter the manner it conducts concern, it will be hard to alter the informations warehouse to back up it. The 2nd technique that is used hive awaying information is called database standardization. With this technique, the information is store in a 3rd normal signifier. While adding informations is easy, bring forthing studies can be boring.DecisionAs a decision, informations excavation can be good for concerns, authoritiess, society every bit good as the single individual. However, the major defect with informations excavati on is that it increases the hazard of privateness invasion. Currently, concern organisations do non hold sufficient security systems to protect the information that they obtained through informations excavation from unauthorised entree, though the usage of informations excavation should be restricted. In the hereafter, when companies are willing to pass money to develop sufficient security system to protect consumer informations, so the usage of informations excavation may be supported.

Contingent Workers Overused & Underpaid

Contingent Workers Being Overworked and Underpaid â€Å"Inside Amazon’s Warehouse†Ã¢â‚¬â€Morning Call 09/17/11 I found this article particularly interesting because it is local and it shows the abundance of temporary workers in this job market and how they are willing to be treated to keep a job and have income even if it is only $11-$12 an hour. Integrity Staffing Solutions is the company that hires temporary workers for the Amazon warehouse in Breinigsville, PA. These temporary employees are told by ISS that if they work hard while in this position they may be hired into permanent positions but this rarely happened.The temporary positions would end after a number of hours and then they can re-apply for these same positions within a few months. The reality was that many of these temporary workers never got offered or â€Å"promoted† to a permanent position though. This is said to be the future for many companies in that they hire more temporary staff than perma nent because they do not expect benefits and will work for lower pay. Warehouse positions such as this are very high demand both physically and mentally. Related article: Advantages and Disadvantages of Foreign Workers in MalaysiaMany of these workers were pushed harder and harder until they got injured or physically could not complete the responsibilities of the job anymore. With them being temporary workers they would just be let go and then another temporary worker would be assigned to this same position. It is an ideal world for Amazon because they always have fresh blood in the warehouse. This was taken from the article and highlights many of the key points I had just mentioned, â€Å"The situation highlights how companies like Amazon can wield their significant leverage over workers in the bleak job market, labor experts say.Large companies such as Amazon can minimize costs for benefits and raises by relying on temporary workers rather than having a larger permanent workforce, those experts say. † The treatment of all workers was highlighted in the article with interviews of over 20 current or previous employees of Amazon . These positions were physically demanding and people could not keep up with the increasing demands that were handed down by the company.They talk of the heat index in the summer in the warehouse would reach over 100 degrees and they would have ambulances waiting outside the building to assist people. If a temporary worker became ill or couldn’t physically do the job anymore their assignment would be terminated and they would no longer have a job. This created fear amongst the temporary staff and most of them pushed through the pain and continued working so that they could keep the job because it was income even if it was only $11-$12 an hour. http://www. mcall. com/news/local/mc-allentown-amazon-complaints-20110917,0,1246510. story

The Motion Picture Production Essays

The Motion Picture Production Essays The Motion Picture Production Paper The Motion Picture Production Paper Film noir’s transformation can be partly explained by changes in how Hollywood’s strict Production Code was enforced. Instituted by politician Will Hays in 1930, imposed rigid guidelines for motion pictures and demanded that they provide morally clean, uplifting, generally sanitized fare for the viewing public. The code’s three chief principles were: 1. No picture shall be produced that will lower the moral standards of those who see it. Hence the sympathy of the audience should never be thrown to the side of crime, wrongdoing, evil or sin. 2. Correct standards of life, subject only to the requirements of drama and entertainment, shall be presented. 3. Law, natural or human, shall not be ridiculed, nor shall sympathy be created for its violation (Bynum) It also demanded that film respect the sanctity of marriage, honor patriotic values, never â€Å"throw sympathy with the crime as against law and justice,† and inspire moral uplift (Bynum). Thus, Hollywood studios had to tailor their films to adhere to the Code, creating difficulties for the film noir genre, which espoused a rather cynical view of humanity, especially of women, and presented a much different message about society and human nature than the Code demanded. Essentially, the Code demanded morally acceptable messages, particularly that crime and aberrant behavior had consequences. Film noir was hardly uplifting or patriotic, and its focus on seedy or disreputable characters made it seem anathema to its mandates, but it adhered to the Code by punishing characters who violated these values. If transgressions were shown on screen, they had to be somehow punished, so that the upright values the Code practiced ultimately prevailed. Thus, in film noir, the villain never really got away with his crimes. If innocent victims were murdered, their killers met justice in some way. The Postman Always Rings Twice embraces a sort of strange cosmic justice prevails, since the wrongdoers receive punishment for their misdeeds – both Frank and Cora are punished for committing both adultery and murder with their lives. Also, in Kiss Me Deadly, the treacherous Lily meets a well-deserved fiery death, while the good Velda is spared. Touch of Evil breaks from the established formula; Quinlan’s corruption leads to his death, but (interestingly) no women were punished. The Code’s enforcement did fluctuate, however; the strict Joseph Breen retired in 1954, and his more tolerant successor, Geoffrey Shurlock, permitted once-taboo subjects to appear onscreen without penalty. This explains Touch of Evil’s open discussion of drug trafficking and the implication of prostitution; however, Marlene Dietrich’s madam character does not lure any of the film’s male characters into her trap, so she is not punished for anything. She is a clearly shady character, but not presented as an evil vamp, but rather as a faded temptress and thus not genuinely dangerous. Essentially, female characters got what they deserved, though the scope of what they were allowed to do had broadened. Women in film noir reflected changes not only in Hollywood’s production codes but also in American morality and gender roles. The earliest films in that genre reflected America’s stricter expectations of women and a more straitlaced moral standard; women who violated those were intriguing to watch onscreen, but only if they received punishment for breaking taboos. As time progressed and moral standards loosened, film noir’s women were less likely to fit rigid archetypes or receive punishment for activities that no longer seemed quite as shocking. The film noir woman thus reflected changes in American morality and views of women, which relaxed as women’s sexuality was gradually better understood and accepted.

Identifying a Bug vs Insect

Identifying a Bug vs Insect The word bug is often used as a generic term to refer to any type of small crawling critter, and it is not only kids and unknowing adults who use the term this way. Many scientific experts, even trained entomologists, will use the term bug to refer to a wide range of small creatures, especially when they are speaking conversationally to the general public.   The Technical Definition of a Bug Technically, or taxonomically, a bug is a creature that belongs to the insect order Hemiptera, known commonly as the true bugs. Aphids, cicadas, assassin bugs, ants, and a variety of other insects can claim rightful membership in the order Hemiptera. True bugs are defined by the types of mouthparts they possess, which are modified for piercing and sucking. Many members of this order feed on plant fluids, and so their mouths have the structures necessary to penetrate plant tissues. Some Hemipterans, such as aphids, can badly damage or kill plants by feeding in this way. The wings on Hemipterans, the true bugs, fold over one another when at rest; some members lack hind wings altogether. Finally, true bugs always have compound eyes. All Bugs Are Insects, but Not All Insects Are Bugs By the official definition, a large group of insects arent considered bugs, although in common usage they are often lumped together under the same label. Beetles, for example, are not true bugs. Beetles are structurally different from the true bugs of the Hemiptera order, in that their mouthparts are designed for chewing, not piercing. And beetles, which belong to the Coleoptera order, have sheath wings that form hard, shell-like protection for the insect, not the membrane-like wings of the true bugs.   Other common insects that do not qualify as bugs include moths, butterflies, and bees. Again, this has to do with structural differences in the body parts of these insects.   Finally, there are a number of small crawling creatures that are not insects at all, and so cannot be official bugs. MIllipedes, earthworms, and spiders, for example, do not possess the six legs and body segment structures found in insects, and are instead members of different animal orders- spiders are arachnids, while millipedes are myriapods. They may be creepy, crawly critters, but they are not bugs.   Common Usage Calling all insects and all small crawling creatures bugs is a colloquial use of the term, and when scientists and otherwise knowledgeable people use the word in such a way, they are usually doing it to be down-to-earth and folksy. Many highly respected sources use the word bug when they are writing or teaching certain audiences:   Gilbert Waldbauer is a respected entomologist from the University of Illinois. He authored an excellent volume called The Handy Bug Answer Book  which covers everything from scorpions to silverfish.The University of Kentuckys entomology department hosts a website called the  Kentucky Bug Connection. They include information on keeping pet bugs, including tarantulas, mantids, and cockroaches, none of which are actually bugs.The  University of Floridas entomology department  has sponsored a Best of the Bugs award honoring for outstanding insect-related websites. Among their honorees are sites on ants, beetles, flies, and butterflies- no actual true bugs.Iowa States entomology department hosts one of the best arthropod sites around- Bugguide. The site is a database of information and photographs collected by amateur naturalists, covering virtually every North American arthropod. Only a small portion of the species listed belong to the order Hemiptera. A bug is an insect, but not all insects are bugs; some non-insects that are called bugs are neither bugs nor are they insects.  Is everything clear now?

The World is So Big, Yet So Small

The World is So Big, Yet So Small We sit in our chairs behind desks or at the kitchen counter on our laptops, and feel protected from the world yet a part of it. The shy parts of us try to convince us that we are just as connected as if we were on tour. The web has joined us all together. Then we wonder why we dont have followers, or why we arent selling books. Anyone can throw up a blog. Anyone can buy an ad, and goodness knows anyone can toss a book on Amazon. All of that does little for your platform. That is . . . unless you have a blog that knocks the socks off people thanks to your controversial way of presenting things, or your works wax ridiculously lyrical. Blogging about your life, your day, your thoughts on writing . . . how is that different from the next one hundred blogs What Im trying to say is there is nothing magical about putting yourself out on the web. Followers dont suddenly find you because you purchased a domain name and hired someone to build you a WordPress site. You arent Kevin Costner, and people dont come to your blog because you built it. If Ive learned anything in the book side of my profession, its that people want to see you. Ive spoken to a room of three hundred or as few as two. Some appearances are more predictable than others, but the truth is you present with the same quality and passion. These folks are there to see you, experience you, learn from you. You might be amazed at how much they appreciate you putting yourself out there, with some of the most loyal fans coming from small events. Most of my strongest supporters have met me. From a library in Bettendorf, Iowa to a writers conference in a rec center cafeteria in Wadesboro, North Carolina. From the basement of a bank in Black Earth, Wisconsin to the sun porch of a home in Newberry, South Carolina. When you meet people, make eye contact, and read their body language, you form a more memorable bond. The writer becomes real, more worthy of endorsement because they took the effort to be there in the flesh. That took planning, driving, the cost of travel. Be willing to genuinely meet people. Dont hide in a string of twenty authors. Be willing to smile and share a minute with a stranger. Dont forever hide behind your screen. Yes, the world is huge, but making the effort to shrink it and stretch your social skills with a handshake and real conversation forges long-time fellowship. Thats the strongest platform you can create. And you dont have to travel the globe to find it. Your hometown venues work just fine.

Nothing much is known about heat waves because heat waves are usually not seen like hurricanes, tornadoes and other such things. Hyperthermia and dehydration are commonly caused because of heat waves; these can be very deadly and at times life-threatening also. Crops are also damaged because of extreme heat waves, heat expansion and heat cramps are also commonly caused by heat waves. The dry soil erodes affecting agricultural land; no agricultural activities are possible once the soil is eroded. Temperature is often increased overnight by several folds because of the urban heat island.

Discuss the reality of using problem solving and solution generating Essay

Discuss the reality of using problem solving and solution generating tools in a real consultancy case - Essay Example The third step is the evaluation and the selection of the best alternative, based on how much the option will solve the issue without causing negative results; that all parties accept the option taken; that the alternative is practical, and that the option is fit for the constraints of the problem. The fourth steps are implementing and follow up on the solution, which is done through campaigning for the acceptance of the option among involved parties and involving their efforts. This tool is more effective as compared to others like random idea generation, provocative idea formulation, challenge idea formulation and concept fan formulation and disproving. This paper is a discussion of the reality of problem solving and solution generating tools, through a real case of consultancy (Old 1995). The consultancy case used for this study is that of Veema Enterprises, whose management and stakeholders were interested in capturing an outside perspective – in the area of identifying the opportunities available to the venture, for improvement in the area of management. The venture sought to diagnose areas of improvement, define fresh perspectives – while remaining appropriate to regulated service, as well as place focus on managerial practices and areas of proficiency, which can be controlled for long-term success. This can be supported by the theory of constraints, developed by Goldratt Eliyahu in 1984, covering a set of insights and holistic processes – all founded on systems approach to mange and simplify the complexity of the enterprise, by focusing on the logical and physical limiting areas. For the enterprise, these constraint areas include leadership inefficiencies, strategic planning deficiencies, decreasing quality and the lack of innovation. This pr ocess can also be explained using Kurt Lewin’s theory of 1951, which explains behavior as the product of a dynamic balance of opposing forces. The theorist talks

A Successful Manager Assignment Example | Topics and Well Written Essays - 1500 words

A Successful Manager - Assignment Example I believe success means being able to deliver what is expected of you in your professional line and even better. Many believe that success is being better than your friends or relatives. According to me, success means being better than I was yesterday. Material possession should not be a way of measuring success, but according to how much one has improved from the previous day. To improve personal limitation one needs self-awareness. Some of the elements included in it are goals, values, and abilities. This will help a person become a better manager in future. Self- awareness encourages someone to things they thought they could not. Self-awareness, in turn, helps someone to get to self-actualization. This is where one is able to do any task because they believe in themselves. They may also have the skill that even gives them more confidence. Being hesitant to study abroad, I got motivation from when I saw other student graduates from the English learning school so I studied hard and graduated. To improve a personal and professional relationship, self- closure is important. It also helps improve one’s understanding and concern about a situation. It also improves the quality of communication, collaboration, and performance with others. Trust is a very important element in business. In business, one should be ready to share in case of a problem. It helps to share because one will get help and get different views that they can combine and be unstoppable. A person with self-management skill is very lucky. This means they can manage their emotions, time and stress. Time is one of the most important elements in business, therefore, should be properly managed and used effectively. Management of stress, on the other hand, is very important for effectiveness in the workplace.

D5 - Essay Example The management style adopted is a bit informal with minimal supervision from the managers (Johnson, 2013). However, despite the obvious advantages, the company’s pay does not match the physical and manual output rendered, coupled with the long working hours of the employees (bad work/home life balance). In addition, there’s a communication disconnect between management and employees in the smaller branches, since communication is heavily centered on the big stores. There is need for improvement in management structure to curtail inefficiencies in distribution and sales sectors and promote educated personnel. The company’s market and growth opportunities lie in partnering with the 8th Wonder Brewery and distribution to sport franchises. According to Corenbleth, Glazer’s is a competitor of Silver Eagles Distributors and deals with the distribution of alcoholic beverage such as spirits, malts and wines. The company’s distribution not only covers the U.S (Texas, Mississippi, Missouri, Arizona, and Oklahoma) but other countries such as Canada. The company, which was founded in 1909, has more than 100 employees and a sales revenue of around $3.8 billion. Just like Silver Eagles Distributors, its good financial position has contributed to its low risk credit rating. However, despite the similarities, Glazer’s has a bigger distribution network and has been ranked as among one of the top 150 biggest private companies by Forbes (Corenbleth, 2011). Stanford-McIntyre states that some of the advantages of the company include the high quality of their products, effective distribution network and competitive wage structure for their employees, good work/home life balance and strong job security. However, there are some disadvantages such as the poor wage structure for sales personnel and insufficient room for career

History of Pueblo Revolt Essay Example for Free

History of Pueblo Revolt Essay â€Å"Every piece of written history starts when somebody becomes curious and asks questions.†[1] In Weber’s compilation he gathers several of these curious peoples works and binds their writings together to form a sort of continued discussion. Arguing from different sources and coming from different backgrounds, they indubitably arrive at different conclusions. From Garner to Gutià ©rrez and from Chà ¡vez to Knaut, they all are part of a continued dialogue on what that caused the Pueblo Revolt of 1680. By addressing the readings as a sum instead of individual accounts, one can gain a more detailed view. While some poke holes in others theories, most of the time, the writers simply offer different perspectives. The vast range of the arguments speak to the difficulty of the topic. Examining an event (or series of events, as the case may be) 300 years ago is an arduous task, but trying to determine causation of such events is even more cumbersome. Typically numerous factors exist and to give these factors any sort of rankings requires a fair bit of perspiration on the part of the researcher. This essay will attempt to evaluate this eclectic mix of commentaries to sift out the strong arguments from the weak. In 1598, when Juan de Oà ±ate arrived in northern New Mexico with a small group of colonists to Pueblo country, Spain demanded payment of tribute and the friars demanded allegiance of religion. For over 80 years Spanish lived with Pueblo before the revolt multiple generations.[2] As Knaut points out, that as â€Å"colonists were isolated from the south in a land where indigenous inhabitants numbered in the tens of thousands†, meaning there was plenty of contact between the two groups.[3] Within that time families intermarried, and a large mestizo population arose, creating an intersection in the Venn diagram of early New Mexico. What Knaut argues in Acculturation and Miscegenation is not necessarily as hard as the others to prove who or what caused the revolt, but rather works in earnest to present what he sees as the creation of a mixed culture, with syncretism occurring on both sides. Perhaps in this essay more questions that answers are created why after 82 years of livin g together would the Pueblos revolt? Garner has a more direct answer to this question. He, unlike Knaut, does not spend as much time underlining the syncretism that occurs, but spends more time examining the relationship between Pueblo and Franciscan, and reigning in the perhaps unfair harshness of previous works in relation to the government. Garner believed that drought, famine and Apache raids caused the revolt, shedding the competing notions that religious incompatibility or having a suitable leader as primary causes.[4] The two arguments in the proceeding articles before Garner that religion was the primary cause fall flat from Garner’s lens. In one instance, he cites the friction between Father Isidro Ordonez and Governor Pedro de Peralta as a result of the governments unfair treatment of the Indian. Peralta eventually decides to have Ordonez arrested, but the colonists (or ecomenderos) proceed to abandon the governor.[5] Garner goes on that governors of early New Mexico are interpreted in a negative light primarily because â€Å"documents are strongly biased against them.†[6] He explains that the reason that these documents are so biased is because of the natural tension between the writers of these records, the Franciscans, and those whom they wrote about, the governors.[7] Garner continues to impress that the Franciscans were the friend to the Indian and foe to the governor. He cites Scholes who states, â€Å"the religious and economic motives of empire were antagonistic if not essentially incompatible.† Having earlier established a different relationship structure than what was typically seen, (a shift from the Hispanic-Pueblo dichotomy to a more complex relationship of priest-Indian-mestizo-colonist-governor) Garner then moves on to the crux of the issue the cause of the revolt. â€Å"The kind of peace that had been pervading New Mexico was contingent upon relative prosperity,† writes Garner. The Spanish had used their organizational skills to create surpluses in the Pueblo economy but the famine of 1670 was so implacable it essentially collapsed the system. The drought of the 1660s the precursor to the famine was so severe it caused â€Å"Indians and Spanish alike to eat hides and straps,† as written by Fray Francisco de Ayeta in an account to the King. In the face of such an oppressive environment, Indians naturally began to question why Spanish controlled their food source. This, coupled with a new emphasis on nativism, turned up the heat and brought the already tense situation to a simmer. This movement towards nativism perhaps may have been a reaction to Indian culture sprouting up in both mestizo and Spanish life. Garner continues on this thread noting that Governor Lopez de Mendizabal was forced to â€Å"crack down on Pueblo religious and cultural activity.† While syncretism among the Pueblos was tolerable, among the Spanish it was viewed as inexcusable. These two factors were the foci of the Pueblo Revolt of 1680.[8] In contrast, the setting that Bowden and Gutià ©rrez attempt to construct in their essays is a religious clash, one that, while not noticeable immediately, was exacerbated by the droughts and famine. After introducing the essay, Bowden then discusses the similarities of the Pueblo religion, and then highlights some of the missteps the Franciscans took in their interactions and, most of all, the conversion process. First they insisted that the Pueblos should learn Spanish, and â€Å"almost without exception,† failed to make any attempt to learn native language. Also, they instituted mandatory mass attendance for all Indians but strangely not all Spaniards. On top of this, leaders who continued practicing the previous traditions were whipped or executed.[9] (27-28) Bowden raises a number of valid points the Franciscans do not appear to be the same persons that protested against the injustices to the Pueblos by the Governor Peralta. Rather, they seem to be creators of an oppressive environment that was quite insensitive to the Pueblo people. However, if you note Bowden’s sources, he cites textbooks for his long diatribe. Garner, in contrast, relies heavier on topic specific articles written by respected names such as France V. Scholes and Jack D. Forbes. While Bowden’s sources are legitimate, he seems to be using information that is more generalized, and not as focused on the relevant issues. Gutià ©rrez points to â€Å"loss of authority† among the Franciscans as the central reason for the revolt.[10] He notes that this gradual loss of power began in 1640s. Because of the uncertainty and unease that followed, the Friars pushed for more drastic measure to balance out this loss of power a crackdown on syncretism and an emphasis on martyrdom. But the connections that Gutià ©rrez makes are weak; he points to the loss of power in the 1640s, but does not cite any kind of example to support his point until 1655.[11] In addition, most of examples of this â€Å"loss of authority† do not come until the mid 1660s and the early 1670s in the midst of drought, quarreling among Spaniards and attacks by Athapascan raiders. And Gutià ©rrez’ examples of Franciscan brutality arise, interestingly enough, around the time that Garner points to heavy handed response by the Spanish to combat syncretism. Gutià ©rrez’ illustrations seem to support Garner’s idea of the Indians being â€Å"like children in a new world and entrapped in the struggle between the Franciscans and Hispanic community.†[12] Angà ©lico Chà ¡vez provides yet another take on the Pueblo Revolt. While Gutià ©rrez, Garner and Bowden all spend considerable time on relations, Chà ¡vez as his title Pohà ©-yemo’s Representative and the Pueblo Revolt of 1680 puts much more emphasis on establishing a new leader as a primary cause of the Pueblo revolt. Chà ¡vez seems to avoid tackling the revolt squarely (like Knaut) partly because he devotes most of his time supporting his argument for Domingo Naranjo as the leader (arguably 21 of the 24 pages). Despite Chà ¡vez lengthy narrative supporting Domingo Naranjo, the black leader with yellow eyes, many scholars reject this notion, because it seems to runs counter to what most sources suggest. Historian Stefanie Beninato agrees that Naranjo was a leader, but â€Å"one of several† as â€Å"the concept of a single leader is not viable in the theocratic social structure of the Pueblo world.†[13] Garner too, while recognizing Popà © as instrumental, rejects the idea that he was a â€Å"unique Indian leader,† but rather he arose out of necessity, as opposed to the creation of necessity.[14] While, many critique Chà ¡vez’ uncommon interpretation, it reminds one to reexamine the mestizo and mulatto population in New Mexico. Naranjo, real or not, represents the truth that the black/white Pueblo/Hispanic definition was increasingly blurred in the years leading up to the revolt, and an entirely different culture had emerged. Pohà ©-yemo had multiple windows in to this culture of multiplicity. Garner’s essay seems to be built around the most logic because his essay points to lack of basic necessities as the true cause of the revolt. When there is enough food and prosperity people get along. When there is a shortage, it pushes groups to exceptional measures. Rarely has a revolt occurred without certain factors mitigating access to peoples’ basic needs. Garner also spends ample time with the battle itself, and provides plenty of evidence of to why it was a success; particularly because of the cultural coexistence with the Spanish. Garner is not without flaw he fails to address certain issues, notably that of the presence of a larger mestizo culture. While he acknowledges it somewhat, he seems more preoccupied with the Franciscan-ecomedero versus government dynamic. This oversight, however excusable, provides good reason for holding onto multiple sources while dissecting historical events such as these. In the absence of primary documents, the importance of rigorous scholarship is especially crucial. To hold the works of these â€Å"curious† scholars together stresses the value for careful thought and due diligence.

BoD Lipid Peroxidation Report

BoD Lipid Peroxidation Report A Study of lipid peroxidation The degradative process of lipid peroxidation in the liver and the potential of antioxidants to prevent cell damage Lipid peroxidation of rat homogenate using the Fenton reaction to generate free radicals (-OH and -O2) to initiate the self-propagating peroxidation of cell membrane fatty acids. Two separate antioxidants were used (aTocopherol and Quercetin) to study the potential of antioxidants in the prevention of cell damaged. Data of two separate groups (A+B) was provided along with data enabling the construction of a calibration curve to measure local MDA concentrations as an indication of peroxidation damage. The Fenton reaction produced the highest concentration of MDA in both data sets which is expected, allowing for a comparison of free radical damage in the presence of antioxidants. In the presence of aTocopherol, there was an MDA (nM/ml) concentration reduction from 45nM/ml to 24nM/ml evidencing a peroxidation inhibition via the binding of free radicals to the antioxidant though some damage was still caused as MDA concentration was higher than the control (7nM/ml). Quercetin showed a com plete reduction in local MDA concentration from 68nM/ml to 7nM/ml, which is equal to that of the control; evidencing a complete lipid peroxidation via the binding of all free radicals produced and thus prevents cell damage. Lipid peroxidation is the multistep process of oxidative degeneration of lipids. The process involved polyunsaturated fatty acids and the free radicals -OH (hydroxide) and -O2 (superoxide), which are unstable forms of oxygen to the incomplete valence ring on their outer shell resulting in an unpaired electron (free electrons). Due to the naturally unstable state of a single unpaired electron, free electrons are highly reactive (free radicals) requiring an electron to become stable; making the unpaired hydrogen atoms on the fatty acid tails suitable for binding (Mylonas C, 1999). The three step process (initiation, propagation and termination) of lipid degenerative produces highly reactive electrophilic aldehydes, which react with CH2 group forming CH (carbon centred) radicals. CH radical then reacts with O2 radicals producing peroxyl radicals (Yngo J. Garciaa, 2005). This propagation reaction then reacts with adjacent CH2 groups resulting in the formation of lipid hydroperoxide. Lipids are essential components of cell membranes (i.e. phospholipids and glycolipids) and can be used in the identification of damage as a result of the pathogenesis of disease via reactive oxygen species (ROS) concentration. ROS-dependent tissue damage can be identified by increased local MDA (malonedialdehyde) and 4-HNE (4-hydroxynonenal) (Kwiecien S, 2014). MDA is the product of lipid peroxides metabolisation, and can be indicative of oxidative stress related disease i.e. atherosclerosis, and induced gastric injury (due to gastric mucosa damage). Due to free radicals are reactive its uncommon that they a found in that state as they tend to bond and react very quickly in order to fill their valence shell and become stable. The Fenton Reaction (Fe2+ and H2O2) issued to generate free radicals (particularly -OH) and initiates lipid peroxidation within the liver. During the breakdown of lipids, malonedialdehyde (the final product of lipid breakdown) reacts with thiobarbituric acid resulting in a testable pink adduct. The Fenton reaction is as follows: Fe+2 + H2O2 > OH (hydroxyl ion) (Fenton Reaction) OH + lipid > malonedialdehyde Malonedialdehyde + thiobarbituric acid > thiobarbituric acid reactive substance (pink) Set up a series of test tubes a labelled and the volumes laid out in Table 1 were pipetted into the corresponding tubes. Remember to add the rat homogenate last due to this starting the reaction. The tubes were then incubated for 30 minutes at 37 degrees Celsius. At this point, the standard curve of MDA was set up as seen in Table 2 and tested at a wavelength of 532nm. After which thiobarbituric acid was added to the original test tube set and incubated for a further 15 minutes in after the adduct fluid was removed and tested at 532nm.

The data set in Table 4 was provided and used the antioxidant aTocopherol. Seven repeats of each test were conducted to allow for a mean to be gained and thus a Stdev and then a standard error mean. The error mean allows for comparisons between different data sets as it indicates how accurate the experiment was rather than how varied (Stdev). The data was plotted in figure 2 and 3 with the variation of containing either the Stdev (figure 2) or the SEM (figure 3). Figure 2 allows for variation comparison while figure 3 allows for accuracy comparison between the two data sets (group A and Group B). Figure 2: the mean OD values of aTocopherol, the error bars show the variation within the data set. Test tube 2 was the most optically dense of the data set while test tube 2 was the least, though the error bar would suggest some variation in this value considering test tube 1 (control) was more optically dense. Figure 2 shows the optical density of aTocopherol. Test tube 1 contained only buffer and showed little variation between repeats resulting in a small Stdev, while test tube 4 has a large Stdev value and thus would need repeating in order to gain an accurate representation of the data. Test tube 3 was the most optically dense with a value 0.246 (at 532nm), while the OD went down between test tubes 4-5 (0.167 and 0.130). This is visually shown in in figure 3, where the data was plotted in a bar graph and SEM was used to show the accuracy of the experiment. The deviation of the error bars shows high accuracy in some results i.e. test tube 1-2-3. However, the deviation in test tubes 4-5 was high compared to other samples. Figure 3: the graph shows the class data of group A. The mean OD values of aTocopherol were plotted including the SEM to show how accurate the experiment was between data sets. Test tube 3 showed to be the most optically dense of the set while test tube 2 showed to be the least.   Ã‚   Tube Mean -/+ Stdev MDA concentration (nM/ml) 1 Control 0.058 -/+ 0.025 7 2 Fe2+ 0.054 -/+ 0.029 7 3 Fe2+/H2o2 0.246 -/+ 0.173 45 4 Catalase/Fe2+/H2o2 0.167 -/+ 0.105 28 5 aTocopherol/Fe2+/H2o2 0.130 -/+ 0.666 24 Table 5: a table showing the MDA concentrations of Group A class data set of each test tube using the calibration curve in Figure 1.

Test tube 3 showed to contain the highest concentration of MDA (68nM) while test tube 2+5 also showed to contain the lowest concentration of MDA (7nM). NOTE: Due to individual data being lost only a comparison between the two data class data set can be made The enzymatic destruction (via catalase, superoxide dismutase) of membrane lipids is a crucial step in the pathogenesis of multiple disease states within adult (Mylonas C, 1999), the reactive oxygen species (hydrogen peroxide) produced during lipid peroxidation readily attacks the polyunsaturated fatty acids within the phospholipid bilayer causing the commencement of a self-propagating chain reaction within the membrane due to CH radicals reacting with O2 radicals producing peroxyl radicals (AW, 1998). Due to the self-propagating nature of the reaction series small lipid peroxidation can cause serious tissue damage resulting in atherosclerosis, asthma or kidney disease. Antioxidant activity quenches molecular oxygen (Yamauchi, 2010), and helps in the stabilisation of lipid-peroxyl free radicals via inhibition. Quercetin, a plant-derived aglycone flavonoid (Zhang M, 2011) was compared to aTocopherol (vitamin E) in the lipid peroxidation of rat liver homogenate. The liver metabolises materials and thus results in the production of free radicals when the oxidative balance is lost it leads to oxidative stress and thus having antioxidants to restore homoeostasis is required. Antioxidants have a high affinity for free radicals (Muriel, 2015) due to their ability to donate electrons. The antioxidant a-Tocopherol reduces oxidation under strong oxidative conditions, reducing the number of free radicals to be free at the end of lipid peroxidation. The data in figure 2 shows the average OD including Stdev bars, the variation in tubes 4-5 indicates poor experimental practice resulting in poor repeats within the data set and thus increasing variation within the data set. It suggests high oxidative conditions in tube 3 producing high concentrations of MDA (nM/ml) as seen in figure 4. Figure 4 also evidences that in the presence of a-Tocopherol lipid peroxidation is reduced as a reduction of MDA (the final product of lipid peroxidation and would result in pink adduct) is being produced suggest an interruption in the self-probating cycle of the fatty acids within the liver homogenate. This reduction is evidence as MDA concentration goes from a peak of 45nM/ml to an MDA reduction 24nM/ml in the presence of a-Tocopherol. When comparing the two sets of Data SEM and SD is used in order to give a relative comparison between the two different groups due to them being undertaken under different conditions. Comparing figure 2 and figure 5 (which used SD) the variation in data set A was much more significant as the higher SD values indicating a large variation within the repeats evidencing low reliability. Figure 5s SD bars a smaller then figure 2 indicating less variation and an increased reliability of the obtain results. Though both sets of data (A-B) show that the highest OD was found to be within tube 3 indicating that Fe2+ and H2O2 produce the highest concentration of MDA (nM/ml). SEM of the two data sets show that the accuracy of the two groups are similar and both show a decline in MDA concentration in the presence of the antioxidant, evidencing a reduction in lipid peroxidation (MDA is the product of lipid peroxides metabolisation which results in the pink adduct) and free radical production in the presence of the chosen antioxidants. Using the calibration curve to gain the MDA concentration of each antioxidant shows that quercetin resulted in a total reduction of free radicals as the MDA concentration was reduced to that of the control (buffer solution). Comparing this to a-Tocopherol there was a reduction of nearly half free radical concentration. These results indicate that the levels of oxidative stress are reduced in the presence of antioxidants. Improvements that can be made include, not losing the individual samples which would have been used for comparison, increasing the amount of antioxidants used to show and overall reduction in free radicals in different antioxidants. Also individual human error resulted in data sets begin provided requiring more lab expertise would reduce this and thus reduce was and cost of the experiment. Antioxidants reduce the concentration of MDA (nM/ml) present in the test tube via the inhibition of oxidative stress and lipid peroxidation of the cell membrane lipids. Quercetin completely reduced local MDA concentration of the rat homogenate indication no lipid peroxidation was occurring due to the binding of antioxidant to the local free radicals (produced via the Fenton reaction) due to their naturally high affinity. There was also a noticeable reduction of MDA concentration in the presence of aTocopherol though this was only an estimated 50% reduction. It can be seen that antioxidants offer a level of cell lipid protection against free radicals and a reduction in oxidative stress, resulting in less overall tissue damage.

Stopping the Practice of Female Genital Cutting Essays -- Ethics, Cult

Female genital mutilation is a practice deeply enmeshed in the cultural beliefs of many Africans and select groups around the world. Also, just like any other culture, they will cling even more strongly to their ancient traditions when their beliefs are challenged by people from an outside culture. When someone from another country comes to a tribe to essentially tell them that one of their most basic traditions is wrong, problems usually ensue. This is mainly because, in an African’s point of view, the outsider does not understand the tribe’s beliefs and so has no valid privilege to tell the tribe what they should or should not do. In this way, even if there are a select few men and women that support the foreigner’s view, they run the risk of ridicule or even banishment from their fellow peers and will not step forth to condemn their ages-old practice. To further explain the gravity of this situation, one must understand that in many villages if a woman is not cut, then she is, in the words of Rogaia Abusharaf, â€Å"generally assumed to be promiscuous, a man-chaser.† In other words, â€Å"genital cutting is considered an essential aspect of a woman’s identity.† Thus, decreasing the prevalence of cutting is a very intricate process that involves a deep change in a culture’s social beliefs. I agree with Abusharaf when she states â€Å"without a deep commitment from within these cultures to end the cutting, eradication efforts imposed from the outside are bound to fail† (Abusharaf). Now, the question is how to first initiate these changes within a culture that practice female cutting as easily as breathing. Cutting is not something they openly discuss amongst themselves, but is essentially regarded as a necessary tradition. It is the norm in t... ...understand that death or later sickness a woman can catch is most likely from the procedure. Together, we can help the movement to end FGM and soon no woman or child will have to undergo the unnecessary torture and humiliation from the procedure.
