...regular screening.3 Hispanic women in this region have one of the highest cervical cancer mortality rates in the nation.4 Previous studies have identified barriers to screening in this minority population such as lack of access to healthcare, fear of pain during the gynecological exam and embarrassment.5 Persistent infection with oncogenic Human Papillomavirus (HPV) types is necessary for developing cervical cancer.6 Thus, HPV testing of women 30 – 65 years of age has been added to the cervical cancer screening guidelines in addition to Pap/cytology (co-testing).2 Self-sampling is a novel approach to detect HPV infection, it allows women to collect their own cervical specimen with a brush in the clinic or in their own homes.7 It has high sensitivity (74%) and specificity (88%) compared to physician collected samples.8-13 Women that deem it acceptable cite reasons such as privacy, costs, and lack of need for an office visit.13-21 However, Pap/cytology has been preferred over self-sampling among some groups because of low confidence in self-sampling accuracy and uncertainty over performing it correctly.13,17,20,22,23 Self-sampling has been least likely to be preferred by Hispanic women and those with lower educational levels.13,17 Interventions using a community health worker for group or one-to-one education have effectively increased Pap/cytology uptake among Hispanic women.24-26 However, there are no studies assessing the effects of a culturally sensitive educational intervention...

...DRA Assignment 2 – Recreational Properties 1) FRAMING THE DECISION 1.a) Decisions a) He can exercise the option and buy the land. In this case, the possible decisions are: a.1) Sell the land without any development a.2) Develop the land with a development cost of £ 5 million and the sell it for a higher profit b) He can avoid to exercise the option and invest in another investment that will give to him a certain profit. c) Try to negotiate an option extension in order to be able to delay his decisions until the suit is settled and the risk of not getting the lease does not affect his decision anymore. d) For the purpose of this analysis we are assuming that the price of the option will remain constant. Otherwise another possible decision that Anders may make is whether to sell the option to third parties and eventually recover part of his investments. 1.b) Factors of uncertainty a) Legal suit outcome: the payoff of his decision is subject to the outcome of the lawsuit that may not allow the development of land parcels on East side of White Mountain. b) Reputation: the success of his initiative and the consequent return on his investment are conditioned by the popularity that the location will have, as for instance the quality of the snow and of the ski runs. Due to their nature, these are unpredictable factors that Anders cannot control. 1.c) Objective The objective of Recreational Properties is to maximise the payoff coming from this investment as well as minimising...

...Churn Prediction Vladislav Lazarov vladislav.lazarov@in.tum.de Technische Universität München Marius Capota Technische Universität München mariuscapota@yahoo.com ABSTRACT The rapid growth of the market in every sector is leading to a bigger subscriber base for service providers. More competitors, new and innovative business models and better services are increasing the cost of customer acquisition. In this environment service providers have realized the importance of the retention of existing customers. Therefore, providers are forced to put more efforts for prediction and prevention of churn. This paper aims to present commonly used data mining techniques for the identification of churn. Based on historical data these methods try to find patterns which can point out possible churners. Well-known techniques used for this are Regression analysis, Decision Trees, Neural Networks and Rule based learning. In section 1 we give a short introduction describing the current state of the market, then in section 2 a definition of customer churn, its’ types and the imporance of identification of churners is being discussed. Section 3 reviews different techniques used, pointing out advantages and disadvantages. Finally, current state of research and new emerging algorithms are being presented. given a huge choice of offers and different service providers to decide upon, winning new customers is a costly and hard process. Therefore, putting more effort in keeping churn low has become...

...“You are a department manager in a mid-sized company that provides technology support services. You have ten employees who are required to maintain a high level of technical expertise and deliver excellent customer service. One of your employees, who has been with the company for two years, is performing at a substandard level and you have received numerous complaints from customers and coworkers. In addition, this employee has displayed confrontational behavior which has created a hostile environment. You must now meet with this employee and deliver an ultimatum regarding the need for immediate improvement or dismissal.” Having confrontation and tension at the workplace is counterproductive in most cases. Some professions strive on confrontation (i.e. lawyers and the courtroom) but even these professions have strict guidelines to keep conduct orderly. Delivering an ultimatum is not an easy task, when things get too heated to continue they sometimes are ineffective. Giving the employee a chance to discuss the issues and a chance to improve is fair, unless of course there is criminal behavior involved. In this case, this is not listed. There are many factors that are not given in the example above that leave me to question if the ultimatum should be given. For one, is the employee a “marginalized” one? Is there hostility due to “rejection or lack of conditional acceptance of the reference group” or is there a case of whistle blowing from the peer group (Schockley-Zalabak...

Top Waveform (White) = Output Middle Waveform (Red) = After differential amplifier, before any filtering Last Waveform (Green) = Buzzer Output, R wave detected This output demonstrates that our filters are working well enough to detect Rwaves. Looking at the 4th R-wave in the red waveform, which is before any filtering, we see that the EMG noise is at the same magnitude as the R-wave. However, our buzzer still detected an R-wave. The noise was reduced in such that the R-wave is not clearly above the noise. We are also able to see 60Hz noise filtered out in the output. Digital Circuit Timer Interrupt at 250Hz (Sampling Rate) Verified by checking on the oscilloscope to see a spike every 4ms (250Hz) Analog-to-Digital Converter We inputted the ECG waveform to the microcontroller ADC and graphed the output values. The graph resembles an ECG waveform. This means the ADC was...

...can be diagnosed. This is due to the lack of effective screening methods to detect the tumor or cyst in its earliest curable stages. The ability to successfully detect pancreatic cancer is highly dependent on an effective screening method with high sensitivity and specificity that can detect the tumor or cyst early in its development. In the United States, many of the current methods are too costly, too invasive, unavailable for widespread use, and lack high sensitivity and specificity. There is a strong need to find a more promising screening method that is inexpensive, noninvasive, available for widespread use, and maintains high sensitivity and specificity. The immediate objective of this research project was to evaluate the current screening methods and make a recommendation for a future screening strategy with strong potential to detect the cancer in its earliest stages while improving the sensitivity and maintaining high specificity. The first step in the investigation process was to identify a high-risk population for pancreatic cancer. Then, current screening methods were evaluated based on their ability to detect pancreatic cancer among the defined high-risk population and their cost, invasiveness, availability, sensitivity and specificity. After determining the Magnetic Resonance Imaging (MRI) as the best current screening method, further research indicated that plasma microRNA in combination with the biomarker CA 19-9 has potential to detect pancreatic...

...“One world, one way, one way, many paths.” Well this saying cannot be defined any better in the world of cultural sensitivity. With business activities going global, the organizations are riding the waves of culture more than ever, giving cultural sensitivity an important place in dealings. “Kiss, Bow or Shake Hands?” the international business best seller by Terri Morrison, Wayne A. Conway suggests on how to maintain international relations in different business environment. Cultural sensitivity has taken toll taking business dealings to a whole professional level. Cultural sensitivity means being aware that cultural differences and similarities exist and have an effect on values, learning and behaviour (Stafford). In many cultures establishing relationships is very important while doing business together.” Pulling the plug too soon” as described in an article by Huffington post, people who tend to think that having a basic ‘business goal’ doesn’t work enough and you have to actually work and put your time and effort into it and waiting patiently for the results. Everyone understands that the basic problem of communication is caused by lack of common language. Even when you’re all speaking ‘English’, we don’t seem to understand the reality is that different assumptions based on different cultures can be the main barrier to effective communication. Cultures affect our own attitudes and expectations let alone others. Until recently large firms that operate internationally...

...cancer that is detected early — when it's still confined to the prostate gland — has a better chance of successful treatment. One of the biggest and prevalent issues with prostate cancer is the rates of sensitivity and specificity. Sensitivity and specificity measure the number of false positives and false negatives, and are useful in evaluating the effectiveness of screening methods. Sensitivity is the number of true positive results divided by the sum of the true positive results and false negative results. Specificity is the number of true negative results divided by the sum of the true negative results and false positive results. The article explains that the PSA test and Digital Rectal Examination (DRE) are the most widely used forms of prostate cancer screening. The PSA test is simply a blood test. Even though the PSA is widely available to the general population it’s the sensitivity is 34.9% and the specificity is 63.1% which is not good at all. The DRE test is available by appointment in a doctor's office; there is discomfort for the patient and a risk of slight bleeding. The sensitivity is 27.1% and the specificity is 49.0%, which is worse than the PSA test. To help ensure that the readings will be more reliable most doctors use the two tests together, the sensitivity remains low at 38.0%, and the specificity is 87.9%. Next the article talk about future tests and...

...PERCENTAGES: THE MOST USEFUL STATISTICS EVER INVENTED Thomas R. Knapp © 2010 "Eighty percent of success is showing up." - Woody Allen “Baseball is ninety percent mental and the other half is physical.” - Yogi Berra "Genius is one percent inspiration and ninety-nine percent perspiration." - Thomas Edison Preface You know what a percentage is. 2 out of 4 is 50%. 3 is 25% of 12. Etc. But do you know enough about percentages? Is a percentage the same thing as a fraction or a proportion? Should we take the difference between two percentages or their ratio? If their ratio, which percentage goes in the numerator and which goes in the denominator? Does it matter? What do we mean by something being statistically significant at the 5% level? What is a 95% confidence interval? Those questions, and much more, are what this book is all about. In his fine article regarding nominal and ordinal bivariate statistics, Buchanan (1974) provided several criteria for a good statistic, and concluded: “The percentage is the most useful statistic ever invented…” (p. 629). I agree, and thus my choice for the title of this book. In the ten chapters that follow, I hope to convince you of the defensibility of that claim. The first chapter is on basic concepts (what a percentage is, how it differs from a fraction and a proportion, what sorts of percentage calculations are useful in statistics...

Sensitivity analysis is a “what-if” technique managers use to examine how an outcome will change if the original predicted data are not achieved or if an underlying assumption changes. The analysis answers questions such as “What will operating income be if the quantity of units sold decreases by 5% from the original prediction?” and “What will operating income be if variable cost per unit increases by 10%?” This helps visualize the possible outcomes that might occur before the company commits to funding a project. For example, companies such as Boeing and Airbus use CVP analysis to evaluate how many airplanes they need to sell in order to recover the multibillion-dollar costs of designing and developing new ones. The managers then do a sensitivity analysis to test how sensitive their conclusions are to different assumptions, such as the size of the market for the airplane, its selling price, and the market share they think it can capture. Electronic spreadsheets, such as Excel, enable managers to systematically and efficiently conduct CVP-based sensitivity analyses and to examine the effect and interaction of changes in selling price, variable cost per unit, and fixed costs on target operating income. Sensitivity analysis gives managers a good feel for a decision’s risks. It is a simple approach to recognizing uncertainty, which is the possibility...

Tushar Mahmud | 1120065 | | Abstract: Employee training and development play an important role in the effectiveness of organizations and to the experiences of people in work. Training has implications for productivity, health and safety at work and personal development. The global competition and swiftness of changes emphasize the importance of human capital within organizations, as well as the swiftness and ways of knowledge gaining of that capital. In the economy where uncertainty is the only certainty, knowledge is becoming a reliable source of sustained competitive advantage. Knowledge is becoming basic capital and the trigger of development. Previously built on foundations of possessing specific resources and low costs, present day competition is based on knowledge possessing and efficient knowledge management. Modern organizations, therefore use their resources (money, time, energy, information, etc.) for permanent training and advancement of their employees. Organizations which are constantly creating new knowledge, extending it through the entire organization and implementing it quickly inside the new technologies, develop good products and excellent services. Employees tends to become absolute, and therefore making...
