...security oriented computing. It can be best described as a strategy to prepare for unavoidable failures. It is a slight alteration from the principle known as recovery oriented computing. Both concepts revolve around the ideology that accidents are anticipated in key aspects and will occur at one point .Security oriented computing operates on a number of principles that ensure its effectiveness. One of this assumptions is that all security controls are vulnerable and may end up causing inaccessibility of the intended service or even worse, unauthorized users. This helps the particular organization be on high alert and ensure that their security controls are monitored at all times .Another assumption is that all people conducting alterations or configurations to the system may introduce loopholes to the latter due to wrongful installation or a mistake made during the configuration. The third assumption is that all people conducting day to day operations are subject to make normal errors if the computer allows them to. Interfacing with humans creates situations that increase the margin of error due to factors such as assumptions, fatigue or improper training. In corporate computing environments where thousands of nodes, applications and processes exist, the probability of a normal error to occur are significantly high to the extent that it is mathematically possible to prove that it is next to impossible to prevent such errors from...

...feedback to pupils provides an opportunity for them to see how the respond given to their works which may be engaging or just being ignored by pupils. However, the teachers may have their own perspectives and beliefs underlying their practices. Therefore, this study aimed to identify the way teachers give written feedback to pupils’ writing, belief of their practices and factors that influencing their belief on practices in written feedback. A number of writing exercise books selected from upper level primary pupils are collected to be analysed and a few follow- up interviews being done to elicit the information data required for the purpose of this study. The results shows that most teachers focus more on the language form, giving uncoded error feedback and less written commentary given in writing. It is assumed that the factors that influence these practices are mainly because of examination culture, the time constraints and the teacher’s personal belief of written feedback. CHAPTER 1 INTRODUCTION 1.0 Introduction Written feedback is a long-standing educational practice that can arguably be linked to almost everything we learn (Evans, Hartshorn, McCollum, & Wolfersberger, 2010; Hattie & Timperley, 2007). According to Hyland & Hyland (2006), teacher written feedback is designed to carry a heavy informational load, offering commentary on the form and content or other aspects of a text to encourage pupils to develop their writing and consolidate learning...

...Errors, Risks, & Failures CIS 324-014 December 16, 2012 Errors, Risks, & Failures Errors, Risks, and Failures occur frequently in computer technology. Some of them are very simple, and others are catastrophic, costing money, time, and sometimes lives. Not all can be completely avoided, but through proper software and hardware design, development and testing, a great deal of them would be decreased. Planning and good software designs are crucial in producing a safe, functional, finished product. When you are building a large software project, you will usually be overwhelmed by the overall complexity. Humans are not good at managing complexity; they are good at finding creative solutions for problems of a specific scope. A basic strategy for reducing complexity to magageable units is to divide a system into parts that are more handy. As you divide the systems into components, and further, components into subcomponents, you will arrive at a level where the complexity is reduced to a single responsibility. (Peters, 2012) I think that if the company doing the development takes the time to really communicate with the customer and find out the specs of the project and then takes the time to devise a good design, it sets up the project to become successful. According to A Gift of Fire, some contributing factors causing computer system errors and failures include, not enough attention paid to possible safety hazards, interaction with physical devices...

...Planning strategy was once predominant in the 1960s and 1970s. Although it faltered in the 1980s and 1990s, it still continues to be a significant influence today. While the fact that many industries continued to experience turbulent was the main reason of the fall of planning strategy, it also accounted for the rise of the emergent strategy. Entrepreneurial organizations increasingly rely on emergent strategy development rather than formal planning processes (Fletcher & Harris, 2002). This literature review will attempt to discuss the debate over the prescriptive and emergent approaches for developing strategy followed by the main strengths and weaknesses of the article. The article uses experiences of a craftsman and a potter to develop an argument that the crafting image better captures the process by which effective strategies come to be than the formal planning (Mintzberg, 1987). Mintzberg stresses a strategy is actualized through the processes of learning, negotiation, and proposes that the distinction between planning and implementation is untenable (Mintzberg, 1990). “Openness of emergent strategy enables management to act before everything is fully understood-to respond to an evolving reality rather than having to focus on a stable fantasy.” (Mintzberg, Waters 1985). Emergent strategy is therefore described as a trial and error approach which allows amendments, rather than one fix objective, as in prescriptive strategy (Downs et al 2003). Mintzberg thus believes that...

...Analyzing Running Records Qualitative analysis involves looking at the reading behavior. The teacher looks for behavior evidence of cue use and evidence of the use of strategies such as cross-checking information and searching for cues. She examines each incorrect attempt and self-correction and hypothesizes about the cues or information sources the child might have been using. In Clay's analysis, cues refer to the sources of information. There are three major categories: Meaning- The teacher thinks about whether the child's attempt makes sense up to the point of error. She might think about the story background, information, from the picture, and meaning in the sentence in deciding whether the child was probably using meaning as a source. Structure-Structure refers to the way language works. Some refer to this information source as syntax because unconscious knowledge of the rules of the grammar of the language the reader speaks allows him to eliminate alternatives. Using this implicates knowledge, the reader checks whether the sentence "sounds right." Visual information- Visual information includes the way the letters and words look. Readers use their knowledge of visual features of words and letters and connect these features to their knowledge of the way words and letters sound when spoken. If the letters in the child's attempt are visually similar to the letters in the word in the text (for example, if it begins with the same letter or has a similar cluster of letters)...

...Rajarambapu Institute of Technology Islampur (Sangli), Shivaji University, Kolhapur (India) Abstract: Poka-yoke is a concept in total quality management which is related to restricting errors at source itself. It deals with "fail-safing" or "mistake-proofing". A poka-yoke is any idea generation or mechanism development in a total productive management process that helps operator to avoid (yokeru) mistakes (poka). The concept was generated, and developed by Shigeo Shingo for the Toyota Production System. Keywords— Mistake-proofing, Total quality management, Total productive management. I INTRODUCTION In today’s competitive world any organisation has to manufacture high quality, defect free products at optimum cost. The new culture of total quality management, total productive management in the manufacturing as well as service sector gave birth to new ways to improve quality of products. By using various tools of TQM like KAIZEN, 6 sigma, JIT, JIDCO, POKA YOKE, FMS etc. organisation is intended to develop quality culture.[2,6] The paper is intended to focus basic concept of poka yoke, types of poka yoke system, ways to achieve simple poka yoke mechanism. It also covers practical study work done by various researchers . II What Is Poka Yoke? Poka-yoke is a Japanese improvement strategy for mistake-proofing to prevent defects (or nonconformities)...

...Error Avoidance in Post Modern and Complex Adaptive Systems paper Published by admin on June 2, 2013 | Leave a response Review Exercise and note how might the ideas presented in the reading help you avoid each of these errors? One advantage of the joint postmodern/complexity lens is that managers might avoid some errors that would otherwise be pitfalls. Some of these are identified in the following list. From the perspectives outlined in this chapter, why are these errors? ∙ Failing to account for employees’ ability to learn safe machine operation methods by experimenting on their own with ways to speed up production and thereby reduce the effort they are required to use. ∙ Putting all employees through the same orientation program regardless of differences in cultural interpretations of organizational hierarchies and thereby missing the potential for conflict among employees and between employees and management caused by different expectations of roles. ∙ Disciplining one employee, expecting a modest change in that employee’s behavior but getting a massive union response. ∙ Changing a work process without considering the role of communities of practice on work performance. ∙ Assuming that employees will not reallocate work assignments based on their perception of the best arrangement even after receiving work allocation assignments from management. ∙ Ignoring the speed with which the informal organization can transmit messages and, therefore, failing...

...Chapter 1 INTRODUCTION 1.1 Background of the Study It has been said that modeling the learner is the central aspect of intelligent tutoring systems. This realization spurred the development of student modeling systems or systems that diagnose student errors. These systems proved to be effective in areas like mathematics (subtraction, highschool algebra, differentiation) and computer programming (Pascal, Lisp,C++). The essential elements in constructing a student model are the background knowledge and the student behavior. The first component which is the background knowledge is difficult to acquire automatically and to extend, and in fact one of the major bottlenecks in the development of student modeling systems. The difficulty lies in constructing the bug library, which is the collection of common errors made by the students in a particular domain (Sison,1998). This implies that the background knowledge is a critical component in student modeling construction. Indeed, few systems are able to construct and extend bug libraries. The second component, which is the student behavior can be classified as simple and complex (Sison, 1998). Simple behavior involves classification and complex behavior involves problem solving task. Traditionally, in domains wherein the student behavior is simple (subtraction), student modeling systems used multiple behaviors as the primary input. This is known as synthetic student modeling. One drawback of this is that, the modeling system might construct...

...Influence of time pressure on aircraft maintenance errors TAKAHIRO SUZUKI, TERRY L. VON THADEN, WILLIAM D. GEIBEL University of Illinois at Urbana Champaign Introduction Even though proper maintenance is crucial for aviation safety, tracing the effect that human error in maintenance operations has on accidents and incidents remains a difficult task. According to a UK Civil Aviation Authority study (2003), maintenance and inspection deficiencies ranked fourth (12%) as a factor in aviation accidents overall. Other studies have described that as technology has improved, aviation accidents attributed to mechanical failures alone have decreased, yet those attributed to human error have not shown the same reduction (Wiegmann & Shappell, 2003). Aircraft maintenance requires high reliability and is an important concern in the human factors realm for several reasons. On the one hand, automation, which has reduced flight crew workload, does not apply in maintenance operations (Reason & Hobbs, 2003). On the other hand, maintenance tasks generally access critical areas where human errors lead to serious consequences (Reason, 1997). From a human factors perspective, in the current competitive environment of commercial aviation, occupational opportunities relating to aircraft maintenance technicians (AMTs) are declining. While oil prices soar, fares remain low due to competition (Bond, 2008). Employing fewer technicians and making turnaround at the airport gate shorter are...

...Frequent Errors in English Grammar: Articles and Possessive Markers Keiko Muto-Humphrey 1. Introduction During past decade or so, The Ministry of Education, Culture, Sports, Science and Technology (MEXT) has been making increasing efforts to shift the focus of EFL pedagogy from “correctness and accuracy” in English to “communicative ability” (MEXT 1998). In response to this, much emphasis has been placed on students’ ability to express themselves orally in class. This has, however, had the (undesired) effect of grammar and lexis being minimised in schools. We are now at a stage whereby the overwhelming majority of students enter universities with an insufficient knowledge of grammar and lexis. This paper will examine two error patterns committed by Japanese studying English as a second language: the genitive markers of/’s indicating possession; and the English article system a/an/the. The former is concerned with the misuse of the English preposition of, which I consider to originate in the L1. The analysis shown below manifests that it is difficult for Japanese students to distinguish between of and ’s: a comparison of this will ensue. The latter originates in the misuse/overgeneralisation of learning strategies: the usage of articles: a/an/the. The Japanese language lacks an article system, making this, “one of the greatest problems for Japanese learners [and this] is vividly revealed in the high frequency of mistakes,...” (Kimizuka 1968:78). After analysing the two...

...Scenario #1 Managers fail to account for an employees' ability to learn safe machine operation methods by experimenting on their own with ways to speed up production and thereby reduce the effort they are required to use. This type of failure is an open door to disaster. The key word listed in this error is “experimenting.” No employee should have to learn by experimentation; especially on how to operate machinery. Anything newly introduced to employees should be monitored and failure for this observation to occur can lead to a major catastrophe. Being safe should be the biggest concern for a company and should be the number priority for any organization. Appropriate training is required to operate machinery correctly to avoid a safety hazard for not just for the employee but for the company as well. By adequately training employees on how to operate machinery correctly will minimize accidents by default. It is understandable how speeding up production can become an issue within an organization but before one can perform at their maximum effort/potential, training is required. Therefore that will not only assure the employee know super efficiently how to operate a piece of machinery but will also assure that the individual will perform effectively because of being trained the correct way the machine is supposed to function. Scenario #2 Managers sometimes put all employees through the same orientation program regardless of differences in cultural interpretations...

...Service, a web-based system that provides automated scoring and evaluation of student essays. Criterion has two complementary applications: E-rater®, an automated essay scoring system and Critique Writing Analysis Tools, a suite of programs that detect errors in grammar, usage, and mechanics, that identify discourse elements in the essay, and that recognize elements of undesirable style. These evaluation capabilities provide students with feedback that is specific to their writing in order to help them improve their writing skills. Both applications employ natural language processing and machine learning techniques. All of these capabilities outperform baseline algorithms, and some of the tools agree with human judges as often as two judges agree with each other. 2. Application Description Criterion contains two complementary applications that are based on natural language processing (NLP) methods. The scoring application, e-rater®, extracts linguisticallybased features from an essay and uses a statistical model of how these features are related to overall writing quality to assign a holistic score to the essay. The second application, Critique, is comprised of a suite of programs that evaluate and provide feedback for errors in grammar, usage, and mechanics, identify the essay’s discourse structure, and recognize...

...Billing and coding errors, the causes for billing and coding errors are incorrect dates; this can cause patient information to be billed or sent to the insurance provider to soon or may be late. Double billing happens more often than not. It is sad that it has to happen this way; I believe it is caused by computer errors or misplaced information. If double billing occurs you can credit the doubled amount back to the patient if the patient has paid both amounts. There are also typos that can happen that can happen on a patient’s bill and may cause issues for the insurance carriers, the payers or the patients. The solutions to these billing and coding errors. If the errors occur on your bill, patients can review their billing statements and contact their doctor office. Or they can send a written response asking for the proper information. For typos they can call and provide the correct information and hopefully get a good response from the receptionist. If billed twice for the same amounts they can request a credit for the double charge with proof that it had happened. All coding policies come from the proper coding guidelines of the national medical societies. Thousands of coding and billing combinations are used for checking all ...
