...Anthony Wessel Section 2 HW 1 4. (a). The observational units are the people that went on diets. (b). The explanatory variable is the type of follow up to the diet that is randomly assigned to the observational units, and it is categorical. The response variable is whether or not the dieter regained 5 or more pounds, and this variable is categorical. (c). This a randomized experiment because the treatments are randomly assigned to the subjects. (d). The null hypothesis is that there is no difference between the proportion of people who regained at least 5 pounds after dieting and being treated with each of these follow-up treatments. The alternative hypothesis is that there is at least one of the proportions that are different than the other two, in that the proportion of dieters who regained at least 5 pounds is not the same as the other two proportions. (e). The estimate of the p-value of the MAD statistic is .0008. (f). The p-value of the chi squared statistic in this simulation is .0008, which is the same as the MAD statistic p-value. (g). The chi squared distribution seems to fit fairly well, though it could be a little better and fit a little closer to the data. Based on the two-way table, I would expect the distributions to be pretty similar, because all of the expected counts are above 5, which means that this dataset fits the requirements for a chi squared distribution. (h). The degrees of freedom is 2, the chi squared test statistic is 13...

...Read the scenario. Using the information provided in the references and lesson, arrive with your best possible solution. You are a squad leader in “Sapper” platoon, Special Troop Battalion, 3rd Brigade, 10th Mountain Division. Your unit will deploy to Afghanistan to conduct operations in support of Operation Enduring Freedom. One of your critical tasks in preparing for your deployment is to train your squad on the laws and regulations that we must implement to protect our environment from being damage and contaminated. The 586th Assault Float Bridge (AFB) Company will conduct a five-day FTX in the Anatuvak training area of Camp Yukon. The unit will depart Fort Chilly and convoy 120 miles on limited-access highways. The commander establishes several rest areas and tactical refueling and maintenance points along the route. Reconnaissance team indicated the trip to take approximately 8 hours. Upon arrival at Camp Yukon, the unit will move into the Anatuvak training area and set up a bivouac site, preceded by their quartering party. During the FTX, the company will conduct tactical-bridging operations on the Yukon River. The FTX will involve normal operations (12 to 16 hours a day), with some night and limited visibility operations. The operations will include the use of pyrotechnics and blank munitions. The FTX will not include live fire due to budgetary constraints. The area has hills, wetlands, several winding streams, and one large river. Signs in the area identify and mark...

...11 Issues Chapter of Reporting, Disclosure and Financial Analysis Questions for Review and Discussion 1. The two main adjustment are likely to be the addition of capital assets and longterm obligations. 2. The main adjustments are likely to be: the addition of depreciation expense and gains or losses from the sale of capital assets and the deletion of amounts spent to acquire capital assets and the proceeds from the sale of capital assets the deletion of long-term debt proceeds and amounts spent to repay long-term debts and the addition of any gain or loss on the retirement of debt and the amortization of any debt premium or discount. 3. The key criterion is financial accountability the primary government either appoints a voting majority of the units governing body or a majority of the units governing body is composed of primary government officials and the primary government is able to impose its will upon the potential component unit or there is the potential for the organization to provide specific financial benefits to, or impose specific financial burdens on, the primary government. 4. Discrete presentation is when one or more component units are reported in separate columns, in addition to those pertaining to the primary government. Blending is when the component units transactions and balances are reported as if they were part of the primary government that is, the component units funds are accounted for just as they were funds of the primary government.

...An Analysis of Linux Scalability to Many Cores Silas Boyd-Wickizer, Austin T. Clements, Yandong Mao, Aleksey Pesterev, M. Frans Kaashoek, Robert Morris, and Nickolai Zeldovich MIT CSAIL A BSTRACT This paper analyzes the scalability of seven system applications (Exim, memcached, Apache, PostgreSQL, gmake, Psearchy, and MapReduce) running on Linux on a 48core computer. Except for gmake, all applications trigger scalability bottlenecks inside a recent Linux kernel. Using mostly standard parallel programming techniques— this paper introduces one new technique, sloppy counters—these bottlenecks can be removed from the kernel or avoided by changing the applications slightly. Modifying the kernel required in total 3002 lines of code changes. A speculative conclusion from this analysis is that there is no scalability reason to give up on traditional operating system organizations just yet. but the other applications scale poorly, performing much less work per core with 48 cores than with one core. We attempt to understand and fix the scalability problems, by modifying either the applications or the Linux kernel. We then iterate, since fixing one scalability problem usually exposes further ones. The end result for each application is either good scalability on 48 cores, or attribution of non-scalability to a hard-to-fix problem with the application, the Linux kernel, or the underlying hardware. The analysis of whether the kernel design is compatible with scaling rests on the extent to which...

Strategy: Plans to achieve organization goals. Productivity: Measure of effective use of resources, usually expressed as the ratio of outputs to inputs. Productivity =Output / Input Competitiveness: Organizations compete with each other in various ways including: 1. Price: amount customer must pay for the product or service. If all other factors are equal customers will choose lowest price. 2. Quality: Material, workmanship and design. Quality is related to buyer’s perception. 3. Service: like after-sale such as delivery, setup, warranty, technical support etc. 4. Differentiation: any special feature (design, cost, quality, ease of use, etc) that cause a product or service to be perceived by the buyer as more suitable than competitor’s. 5.

...JFS R: Concise Reviews/Hypotheses in Food Science Food Packaging—Roles, Materials, and Environmental Issues KENNETH MARSH, PH.D., AND BETTY BUGUSU, PH.D. The Institute of Food Technologists has issued this Scientific Status Summary to update readers on food packaging and its impact on the environment. Keywords: food packaging, food processing dvances in food processing and food packaging play a primary role in keeping the U.S. food supply among the safest in the world. Simply stated, packaging maintains the benefits of food processing after the process is complete, enabling foods to travel safely for long distances from their point of origin and still be wholesome at the time of consumption. However, packaging technology must balance food protection with other issues, including energy and material costs, heightened social and environmental consciousness, and strict regulations on pollutants and disposal of municipal solid waste. Municipal solid waste (MSW) consists of items commonly thrown away, including packages, food scraps, yard trimmings, and durable items such as refrigerators and computers. Legislative and regulatory efforts to control packaging are based on the mistaken perception that packaging is the major burden of MSW. Instead, the U.S. Environmental Protection Agency (EPA) found that approximately only 31% of the MSW generated in 2005 was from packaging-related materials, including glass, metal, plastic, paper, and paperboard—a percentage that has remained...

...Story Of Stuff, Referenced and Annotated Script By Annie Leonard Do you have one of these? I got a little obsessed with mine, in fact I got a little obsessed with all my stuff. Have you ever wondered where all the stuff we buy comes from and where it goes when we throw it out.? I couldn’t stop wondering about that. So I looked it up. And what the text books said is that our stuff simply moves along these stages: extraction to production to distribution to consumption to disposal. All together, it’s called the materials economy. Well, I looked into it a little bit more. In fact, I spent 10 years traveling the world tracking where our stuff comes from and where it goes.1 And you know what I found out? That is not the whole story. There’s a lot missing from this explanation. For one thing, this system looks like it’s fine. No problem. But the truth is it’s a system in crisis. And the reason it is in crisis is that it is a linear system and we live on a finite planet and you can not run a linear system on a finite planet indefinitely.2 Every step along the way, this system is interacting with the real world. In real life it’s not happening on a blank white page. It’s interacting with societies, cultures, economies, the environment. And all along the way, it’s bumping up against limits. Limits we don’t see here because the diagram is incomplete. So let’s go back through, let’s fill in some of the blanks and see what’s missing. Well, one of the most important things that is missing...
