(4) Using an example, explain why some variables can only be measured, not manipulated. (1 point) Solution Variables are of many types and are used differently in different situations and experiments. In some experiments like studying cause-and-effect relationship, variables can be manipulated and then observed for their behaviour. However, in certain experiments like correlational studies, variables are strictly measured and cannot be manipulated. E.g. studying correlation between speed and distance. Even if one is manipulated, the other variable will show irregular and distracting trends, signalling manipulation or human error..

Could please answer those questions about North country movie? Here are the questions: What is the deviant conduct? How are labels used and contested? How does the label of deviance as portrayed in the clip relate to social change? Solution Josey during her school days had suffered with a school punishment for caught kissing with her boyfriend. This is something not acceptable as a good act. Josey was raped by her Teacher leading to pregnancy and Sammy\'s Birth. This is highly deviant conduct not acceptable in society. Labels are used on the basis of ones past deeds in society. If someone is acting according to the society rules and manners that are acceptable among public, then he earns respect and good label. If someone is acting against the social acceptance then he will face the same thing in behaviour of people towards her. Earlier when it was not clear that who is Sammy\'s father, Hank was ashamed of Josey but when it became clear that she was targetted by her teacher during school days, Hank started supporting her and also all the support from miners women and family started pouring in for her. And mining company was forced to pay for the sufferings of many other women like her in the mine. So, label of deviance was first the reason for her unacceptance in society later on when she earned a clean image in society, she earned support as well..

A 70-kg individual drinks 2 L/day from a pond outside his house. What he is not aware of is that a factory upstream dumps dichloroethylene in the stream feeding his pond. Assume that he has been drinking this water for 20 years, what are the hazard quotient and the cancer risk of his exposure? Suppose he plans to stay for another 10 years before he retires and moves to Florida, what are the additional risks? (10 points) Additional Information: The pond has a volume of 106 m3 . The feeding stream has a flow rate of 103 m3 /day. The wastewater from the factory 102 m3 /day and contains 1.1 mg/L of dichloroethylene. Neglect the evaporation of water. Neglect the evaporation and reaction of the pollutant. Solution The waste water stream contains 1.1mg/L of dichloroethylene and the prescribed limit is equal 0.1 mg/L, which was derived based on hepatic toxicity reported from compound-specific data. A lot studies done on the drinking water analysis containing dichloroethylene the risk of cancer has not been found but the metabolism product reactive carbonyl compound formed, rather than its electrophilic reactivity, Can be a determinant of carcinogenic potency. These carbonyl compounds were formed by both the radical and the epoxidation pathway and that the protonated forms of the epoxides may also act as the ultimate carcinogens. Apart from this there are a lot of other health hazard by drinking the contaminated water such as: central nervous system depression ataxia, suppression of the righting reflex, ruffled fur, and hunched back Neurological effects, including nausea, drowsiness, fatigue, and vertigo, have been reported following exposure to lower levels. Effects on blood (decreased hematocrit and hemoglobin levels.

2. If you have a nonlinear relationship between an independent variable x and a dependent variable y, how can you apply the least -squares fit method? Does this work for all nonlinear relationships? if not please give an example of a nonlinear equation where the fit method cannot be used.(No need to use Matlab on this question). Solution A)The assumptions of linearity and additivity are both implicit in this specification. • Additivity = assumption that for each IV X, the amount of change in E(Y) associated with a unit increase in X (holding all other variables constant) is the same regardless of the values of the other IVs in the model. That is, the effect of X1 does not depend on X2; increasing X1 from 10 to 11 will have the same effect regardless of whether X2 = 0 or X2 = 1. • With non-additivity, the effect of X on Y depends on the value of a third variable, e.g. gender. As we’ve just discussed, we use models with multiplicative interaction effects when relationships are non-additive. Linearity = assumption that for each IV, the amount of change in the mean value of Y associated with a unit increase in the IV, holding all other variables constant, is the same regardless of the level of X, e.g. increasing X from 10 to 11 will produce the same amount of increase in E(Y) as increasing X from 20 to 21. Put another way, the effect of a 1 unit increase in X does not depend on the value of X. • With nonlinearity, the effect of X on Y depends on the value of X; in effect, X somehow interacts with itself. This is sometimes refered to as a self interaction. The interaction may be multiplicative but it can take on other forms as well, e.g. you may need to take logs of variables. Dealing with Nonlinearity in variables. We will see that many nonlinear specifications can be converted to linear form by performing transformations on the variables in the model. For example, if Y is related to X by the equation E Yi Xi ( ) = + 2 and the relationship between the variables is therefore nonlinear, we can define a new variable Z = X2 . The new variable Z is then linearly related to Y, and OLS regression can be used to estimate the coefficients of the model. There are numerous other cases where, given appropriate transformations of the variables, nonlinear relationships can be converted into models for which coefficients can be estimated using OLS. We’ll cover a few of the most important and common ones here, but there are many others. Detecting nonlinearity and nonadditivity. The key question is whether the slope of the relationship between an IV and a DV can be expected to vary depending on the context. • The first step in detecting nonlinearity or nonadditivity is theoretical rather than technical. Once the nature of the expected relationship is understood well enough to make a rough graph of it, the technical work should begin. Hence, ask such questions as, can the slope of the relationship between Xi and E(Y) be expected to have the same sign for all value.

Why are income statements and statement of cash flows dated similarly. Solution The statement of cash flows measures the sources of a company\'s cash and its uses of cash over a specific time period. The income statement measures a company\'s financial performance, such as revenues, expenses, profits or losses over a specific time period. A cash flow statement shows exactly how much money a company has received and how much it has spent, traditionally over a period of one year. It captures the current operating results and changes on the balance sheet, such as increases or decreases in accounts receivable or accounts payable, and does not include noncash accounting such as depreciation and amortization. A cash flow statement is used to determine the short-term viability and liquidity of a company, specifically how well it is positioned to pay its bills and vendors. An income statement is the most common financial statement and shows a company\'s revenue; total expenses, including noncash accounting such as depreciation; and profit or loss, over a period of one year. An income statement is used to determine the financial performance of a company, specifically how much revenue it made, how many expenses it paid, and the resulting profit or loss from the revenue and expenses. That\'s why these both statements are dated similarly..

What values were affected by simulate airway obstruction, and why? Explain the physiological events that occurred during the simulated asthma attack. Solution Ans: In patients with obstructive lung disease, the small airways are partially obstructed by a pathological condition. The most common forms are asthma and COPD. A patient with obstructive lung disease typically has a concave F/V loop. The air in the large airways usually can be expired without problems, so PEF may be normal. When all the air is expired from the large airways, air from the smaller airways will be expired. With obstructive lung disease, these airways are partially blocked, so the air will come out slower (you can simulate this by blowing out through a straw!). This will result in a lower flow and a (more or less) sharp fall in the flow-volume . FEV1 and FEF25-75 will be too low. Typically the patient will have a normal FVC at the early stages of his condition. The FET (Forced Expiratory Time) will be higher due to the lower flow but equal volume. Historically a Tiffeneau index (FEV1/FVC x 100) less than 70% was considered to be very suggestive for obstructive lung disease. Nowadays the value is compared to LLN. A bronchodilator test will than be performed to assess reversibility. Theasthma symptoms are caused by 3 main physiological events are as follows. Tightening of the muscles lining the airways: This contraction or tightening of the bronchial smooth muscles is called bronchospasm or bronchoconstriction. As these muscles tighten around the outside of your bronchial tubes, causing narrowing, it becomes more difficult to move air through the lung. When this occurs, you may notice shortness of breath, chest tightness or wheezing. Mucus production: In addition to the bronchoconstriction, airways of the lung produce an increased amount of mucus. This can lead to mucus plugging and further narrowing of the airways, making symptoms worse. Inflammation: The inside of the airways become swollen and inflamed. This swelling even further decreases airflow and makes it more difficult to breathe. The inflammation generally occurs later in an asthma attack. Apart from this the person feels · Coughing. Coughing from asthma often is worse at night or early in the morning, making it hard to sleep. · Wheezing. Wheezing is a whistling or squeaky sound that occurs when you breathe. · Chest tightness. This may feel like something is squeezing or sitting on your chest. · Shortness of breath. Some people who have asthma say they can\'t catch their breath or they feel out of breath. You may feel like you can\'t get air out of your lungs. · sweating, itching in the throat, light feeling in the chest, irritation to cigarette smoke, air pollution, chemicals or dust in the workplace, compounds in home décor products, and sprays (such as hairspray)..
