The KGB essays

The KGB essays During the Cold War not much was known about the activities of the Russian state security organization by western intelligence agencies. However after the collapse of the Soviet Union, documents that have been smuggled out by KGB agents (Wilson 1) have allowed agents to see just how much this agency knew and how far the Soviets managed to penetrate into western society. The question is where the KGB operations during the Cold War successful or not? Before the KGB, there was the Vecheka or Cheka, which was started on December 20, 1917 (Crozier 11). The Bolshevik leader Vladimir Lenin created the Cheka, so they would be able to combat counter revolutionary forces in Russia after the Bolsheviks took power. The man who was chosen to lead the organization was Felix Dzerzhinky, also known as Iron Felix, from Poland (11). Not long after the Cheka was founded, it sent a newspaper publisher, Aleksei Filippov, into Finland. Under cover as a journalist, he was sent on various intelligence assignments. This was the Soviets first attempt into international espionage (Andrew, Mitrokhin 24). After the end of the civil war, the Cheka was transferred to the control of the NKVD as the GPU (NKVD.org 1). During its time as the GPU, its mission was to infiltrate the groups of White Russians and Ukrainian nationals to try and destabilize them from within (Andrew and Mitrokhin 32). The GPU, after changing its name many times and switching from being independent or under NKVD control, was brought back under NKVD control as the GUGB after the German invasion (NKVD.org 2). When the Soviets started to push back the Germans, the GUGB regained its independence and became the NKGB. After World War II, Beria, a Politburo member and the ex-head of the MVD, united the NKVD and the NKGB into the MVD (2). After Beria was removed, the MVD was separated with the MVD keeping its original role and the new KGB taking control of state security (3). The i...

True and False Ranges

True and False Ranges True and False Ranges True and False Ranges By Maeve Maddox The combination fromto is often used to express a range of extremes, for example, â€Å"the prices ranged from $1 to $20.† A â€Å"true range† requires a set of objects, persons, topics, or attributes in a limited set. Here are examples of the words fromto used to express measurable ranges: McDowell Mountain Regional Park has more than 50 miles of hiking, mountain biking and horseback riding trails, ranging from easy to strenuous and ranging from 0.5 mile to 15.4 miles.   Childhood is the  age  span  ranging  from birth to adolescence. [Carpenter ants] are large ants ranging in size from one-quarter inch for a worker ant to up to three-quarters inch for a queen. The course in novel writing covered everything from outlining to publication. Birth injuries  range from mild to severe. A â€Å"false range† links disparate items that do not belong in any kind of mutual set. For example: The topics will range from current events in the world and community, to self-expression and topics chosen by the students.   The movie has everything from  comedy to love.   Free shipping on everything from handbags to jewelry [My list of favorites] has everything from Catholic High School Girls in Trouble to Zinc Oxide and You to A Fistful of Yen. Galileos offers everything from luscious wines to generous portions of your favorite Italian inspired food.   Festival has everything from a cake decorating to crocheted peanuts to jousting Such use of false ranges is ubiquitous. The usage rarely causes confusion in the reader, but it does reflect lazy thinking. Avoiding false ranges is easy. If you are not writing about the extremes of a set–like money or ages, or steps in a process–don’t use the word range or the phrase â€Å"everything fromto† Instead, use other words or expressions: The topics will encompass current events in the world and community, self-expression, and additional subjects chosen by the students.   The movie includes comedy and a love story.   Free shipping on all products. [My list of favorites] includes Catholic High School Girls in Trouble, Zinc Oxide and You, and A Fistful of Yen. Galileos offers luscious wines and generous portions of your favorite Italian-inspired food.   Festival features a variety of competitions that include cake decorating, peanut crocheting, and jousting. Note: The error of the false range is especially jarring when it contains more than two items: â€Å"[Joe’s Place] offers everything from  pizza to rack of lamb, to potato pancakes, to meatloaf.† Want to improve your English in five minutes a day?

Authentication Methods and Techniques Research Paper

Authentication Methods and Techniques - Research Paper Example In the simplest form of authentication, a person was authenticated by merely his/her physical appearance and voice as the authenticating party knew the person by face. As the person’s social circle increased, the need to be authenticated arose in environments where the person was unknown to the authenticating party. So the authentication method evolved and pictures were used in the authentication documents (such as passports, etc.). With time, the personal records and private information of a person increased not only in amount (as it became a requirement in schools, universities, offices, banks, airports, hospitals, ) but also in value (credit cards, debit cards, etc.). Means of authentication evolved significantly thereafter as with the availability of this information on public or private networks (e-banking, e-health, e-ticketing, e-commerce), the access points to this information also increased tremendously (on a public network the information is accessible to millions of Internet users all over the world). It was necessary that only the authorized personnel could access the information and so the authentication techniques relevant to the scenario and information worth would have to be brewed up. As the authentication methods progressed, so did the attacks aimed at stealing the private information (Mallow, n.d.). When an authentication method was compromised, an alternative strategy would be looked into for adapting to. This paper gives an overview of the various authentication methods that have been proposed in various applications and literature and have successfully been used for allowing controlled access to private information. The paper also discusses the vulnerability issues associated with each authentication method and assesses it against some important assessment factors. The paper also discusses how to decide the best authentication strategy while living amidst the sophisticated hackers’ realm. 2. Authentication Techniques and Meth ods As mentioned earlier, authentication involves providing a proof to the authority of one’s identity. The various authentication techniques can be listed down into three broad categories; proof by knowledge techniques, proof by property techniques and proof by possession techniques (Jensen, 2003; Cranor & Garfinkel 2005). All authentication methods can be placed into one of these three techniques. The available authentication techniques and methods can be assessed keeping into consideration the major factors of cost, ease of installation, level of authentication and the usability. In this section the various authentication methods alongside their assessment based on these factors is discussed. A. Authentication by Knowledge This category of authentication is based on the fact that only the actual person himself can know some particular information. Examples include text based passwords or Personal Identification Number (PIN) and the response challenges. a. Passwords / PINs Benefits: This type of authentication is the least expensive of all methods as no specific software or hardware is required to set it up. Furthermore, the method is so easy that the users can easily set up or even change the passwords

Singal processing and linear systems + Matlab Essay

Singal processing and linear systems + Matlab - Essay Example The square wave response of a dynamic system measures how the dynamic system responds when a square wave is applied to its input. Generally a unit step function is applied defined by the following equation: Laplace transform and Fourier transform both are use for analysis of aperiodic signals. Laplace yields the result in s-domain where as Fourier transform yields it in frequency domain. Laplace is more often used because in s-domian it is easier to analyze the performance of the system by looking at the poles and the zeros. The Laplace transform is usually used in the context of one-sided signals, i.e. signals that are zero for all values of  t  less than some value. Usually, this "start time" is set to zero, for convenience and without loss of generality, with the transform integral being taken from zero to infinity. The Fourier transform is used for analyzing systems that process signals that are infinite in extent, such as modulated sinusoids. (LTI) The signal is compared both in frequency and time domain, before and after filtering. As seen in the graphs the amplitude of the signal after filtering is 1. The amplitude thus decreases from 2 to 1, showing 3dB attenuation. In frequency domain the higher frequency coefficients are zero. They cover almost half the total bandwidth. Thus the half band filter has made half of the coefficients zero with 3dB

oppertunity costs :: essays research papers

In today’s society, economic decisions made involve the concept of scarcity. There are â€Å"opportunity costs† associated with any choice that you make. In order for an economy to produce more of one type of product, it will be forced to sacrifice units of production of another product. The shifting of resources from the production of one good to another involves increasing sacrifices of the first good in order to generate an equal increase of the second good. This is known as the â€Å"law of increasing opportunity costs.† The economic rational for the law of increasing opportunity costs is that economic resources are not completely adaptable to alternative uses. The opportunity cost of producing a product tends to increase as more of it is produced because resources less suitable to its production must be employed.  Ã‚  Ã‚  Ã‚  Ã‚  Prices are a measure of opportunity cost because they provide information about the value of one product in relation to another.   Ã‚  Ã‚  Ã‚  Ã‚  The shape of the Productions Possibility Frontier, (PPF), illustrates the principle of increasing opportunity costs (Graph 3). As more of one product is produced, increasingly larger amounts of the other product must be given up. In Graph 3, some factors of production are suited for producing both Product A and Product B, but as the production of one of the other brands increases, resources better suited to production of the other must be diverted. Producers of product A are not necessarily efficient producers of product B and just the opposite, so the opportunity cost increases as one moves toward either extreme on the curve of the production possibility frontier. If two products are very similar to one another, the production possibility frontier may be D’Orlando 2 shaped more like a straight line (Graph 2). As an example, let’s say that two brands of wine are produced, Brand A and Brand B. These two brands of wine use the same grapes and the production process is the same. The only thing that is different is the name on the label. The same factors of production can produce either brand equally efficiently. If an increase in production of Brand B goes from 0 to 3 bottles, the production of Brand A must be decreased by 3 bottles. In this case, the two products are almost identical and can be produced equally efficiently using the same resources. The opportunity cost of producing one over the other remain constant between the two extremes

School Behaviour Policies For Children Education Essay

Student behavior has ever been a cardinal issue in any school. Students go to school chiefly to interact with other students in an environment that is good suited for survey and drama. However true, pupils seem to be more motivated in the resort area than in the schoolroom. Behaviour suffers really frequently when these pupils are non every bit motivated as the others. Classify behaviour becomes debatable at the really worst as childs direct their attending off from the existent academic demands of being in school. Teachers and staff of schools are dead set in work outing such issue widening their control of pupil behavior to highs that may non be good to the pupils, every bit good as the school. Disciplinary actions, punitive in every sense, are the most likely to be used to rectify pupil misbehavior. Sir Alan Steer ( 2009 ) in his study found that in the UK, in its schools, there is no demand or want to give schools and its staff wider powers but there is a demand for a â€Å" airing scheme † to be cognizant and to understand the bing powers in school. In his 2005 study, he proposed wider options of legitimate wagess and countenances must be at manus, all of which decently, reasonably and systematically applied by all concerned staff. Lapp has been suggested four old ages subsequently ( Steer, 2009 ) . Findingss have been singular in his 2009 study. He reiterated that â€Å" clear regulations and the consistent application of wagess and countenances † are critical. He rejects â €Å" punitory solution † to bad behavior. Tough love is acceptable but punitory methods are immoral and socially destructive. Several suggestions have been earmarked so as to implement the relevancy of the findings. Steer ( 2009 ) studies: A wages system that is effectual and tied to public presentation in the schoolroom ensures pupil battle and better behavior. Good behavior demands to be learned. It is really imperative to learn childs to act good â€Å" so schools must follow processs and patterns † that will assist pupils on how to act. All staff must be good function theoretical accounts of good behavior. Schools do hold policies that reward good behavior and good work every bit good. Sanctions are in topographic point to streamline the demand for better behavior but what is left out is how to make and implement appropriate wages systems. Simple countenances proved to be more effectual than excepting the kid from category. Statistical informations on behavior betterment must be at manus to hint alterations and complement hereafter actions. Praise can be used to actuate pupils and promote better behavior. Using student tracking system to recognize positive and negative behavior is besides efficient. Motivation and Incentives Motivation has been long considered as a really of import factor in learning. It is the precursor for successful comprehension of the pupils. Geting inducements from good work after a motivative treatment is extremely recommended. Student motive is the involvement of pupils in larning or making academic work ; inducements are methods used to actuate pupils in larning academic stuffs ( Slavin, 1984 ) . Cardinal to this researchaa‚ ¬a„?s aim is to utilize the motivational effects of wagess or inducements in learning. It is long known that motive plays a cardinal function in pupil accomplishment. So, specific in this analysis is the function of motive in behavioral alterations of a pupil in a schoolroom scene. Self-worth and Self-Efficacy In educational psychological science, it is standard runing process to analyze the intrapersonal behavior of a scholar. His or her perceptual experiences of the ego must be taken into consideration in order to happen the appropriate solutions to behavioural jobs. Dignity is linked to the self-concept of ability in any school scene ( Ames, 1990 ) . It is how a pupil considers his ain capacities with regard to othersaa‚ ¬a„? . Self-efficacy is outlook or belief that one can perchance transport out a undertaking. It is task-specific or state of affairs particular. Often, self-efficacy serves as a barometer on a kid ‘s willingness to larn, his set of options in larning and existent public presentation ( Ames, 1990 ) . However, age play a function in how pupils understand ability. Younger childs are more positive or optimistic. They have high outlooks are resilient after a failure. They tend to presume attempt and ability as the same. Older childs are more negative in measuring themselves. Effort for them gives them higher opportunities to win but ability is a set of bounds. Trying difficult and neglecting are really menaces to their self-concept of ability ( Ames, 1990 ) . Students determine self-worth and self-efficacy in relation to their environment. To act ill means self-worth and self-efficacy are dampened by the rigidnesss in the schoolrooms puting. Otherwise, the students are able to get by with its demands. It is here where motive plays its function. Giving wagess or inducements is one motivational tool. To maintain on relaying good behavior and its corresponding benefits, a repeat of good behavior is expected to happen. This is what we call operant conditioning or response support behaviorism. It is the gratifying of a â€Å" partial or random † behavior that which finally leads to the â€Å" desired behavior † ( PBS, 1998 ; Phillips & A ; Soltis, 2004 ) . This molds future behavior. If a wages succeeds a â€Å" response to a stimulation † , so that response is likely to be repeated. Complecting the constructs discussed, this paper plots motive and the self-concept of pupils in the schoolroom through the usage of a reward/incentive system. Changes from their behavior, chiefly their self-worth and self-efficacy will be carefully studied. Methods Based on the premiss above that wagess play a function in actuating pupil behavior, this research is suggesting the efficaciousness of a wages system ( that is reenforcing ) in different schoolroom scene and pupil age groups. With the constructs of operant conditioning, this survey is specifically poised to find how studentaa‚ ¬a„?s self-worth and self-efficacy significantly alterations ( or non ) when treated with wagess or inducements. The Steeraa‚ ¬a„?s studies confirm the value of using such systematically. The research will be utilizing questionnaires and interviews as the primary manner of informations aggregation ( Anderson, 1998 ) . The questionnaires will both aim instructors and pupils as its respondents. Data analysis will be chiefly descriptive and correlational ( Runyon et al, 2000 ; Kirk, 2007 ) . Descriptive informations from socio-demographics will supply the initial analysis. Correlation analysis on pupil and instructor information from the questionnaires will follow thenceforth. The chief part of this analysis lies on the important alterations of pupil self-concept as alterations in the wages systems are put into topographic point. An analysis of discrepancy ( ANOVA ) will make a series of important trials on alterations of perceptual experience by the pupils, i.e. self-worth and self-efficacy ( as dependant variables ) before and after a wages system is placed ( Kirk, 2007 ) . Besides, the age-groups and schoolroom scene will be used as independent variables treated against alterations in self-worth and self-efficacy.

Louisiana Public Schools Essay - 661 Words

For the public schools of Louisiana and across the United States I would propose the expansion of healthcare services provided by the school, an increase in after school and community programs, and the use of a comprehensive curriculum. I would also suggest a decreased emphasis on testing and test results as they apply to school accountability. It is suggested by data from NAEP testing that school absences is one of the factors that has a negative impact on student learning and therefore on overall grade point average and test scores. In a table that shows the coloration of school days missed with the percent of student with a 3.0 of higher grade point average, in the Sioux Falls school district in South Dakota, data suggests that as†¦show more content†¦An increase in healthcare programs provided by schools or by local community centers for children living in impoverished areas could lead to a decrease in absences, and in effect an increase in learning for those students. T he research we have looked at in class, from NAEP and other resources, has suggested that only a limited time of a person’s life is spent in school. We have also learned that education does not come just from school but also from parents and other life experiences. Therefore, I would propose that Louisiana and other states provide more afterschool programs, through community centers or other facilities, that help to enrich education, help to provide positive environments in which children can interact, and provide classes of interest that may not normally be found in most schools. These facilities could also provide tutoring and programs that help integrate the Arts more into education. Student mobility is also a problem facing our school system. Once again, from research we have looked at in class, and from a study I looked at done primarily at the University of Washington on â€Å"Longitudinal Effects of Student Mobility on Three Dimensions of Elementary School Engagement, † it is suggested that students mobility and other factors that arise from it such as stress leaded to a decrease in a student’s ability to learn.
