Econometrics - Assignment Example For RM (average number of rooms in the owner occupied housing in the census tract), in the first variant, a 1 percent change in RM causes 0.329 % change in MV (the median housing price). In the second variant, a 1 percent change in RM causes a 0.0306 % change in the median housing price (MV). Eventually, a 1 percent changes in RM causes a 0.294 % change in the median housing price in the third variant. In the second variable, the weighted distance to five major employment centers in the Boston region (DIS), the order of coefficients; 0.028, 0.027, and 0.027 in absolute values. In the criteria of absolutism, a one percent change in DIS causes a reduction of median housing price by 0.028 in the first variant, a reduction of 0.027 in the second variant, and a reduction of 0.027 in the third variant. In the third variable, nitrogen oxide concentrations in parts per hundred million (NOX), the coefficients are 1.479 and 1.529 in the second and third variants respectively. These figures suggest that 1 percent change in nitrogen oxide concentration increases the medium housing price by 1.479 in the second variant and by 1.529 in the third variant. Beta coefficient is the measure of the sensitivity of the estimates in influencing the median housing price. In the estimates, the beta coefficient is the slope of the model summarized into ÃŽ ²0, ÃŽ ²1, ÃŽ ²4, ÃŽ ²3, and ÃŽ ²2. Normally, the coefficients would imply 1 percentage change in the estimate 1 and 2 would cause an increase of 0.566 and 0.0261. However, using the beta approach, the two coefficients are below, suggesting that they are below the median housing price. 6. Suppose in model (3) I added in the variable NOX DCHAS, resulting in ln(MVi) = ÃŽ ²0 + ÃŽ ²1RMi + ÃŽ ²2 ln(DISi) +ÃŽ ²3NOXi + ÃŽ ²4DCHAS;i + ÃŽ ²5 NOX DCHAS +Æ i . How would the interpretation of Æ 3 change in model (3) after the inclusion of this variable? What is the interpretation of Æ 5 in this model? 9. Given

Terrorist Scene & Aftermath Essay Example | Topics and Well Written Essays - 500 words

Terrorist Scene & Aftermath - Essay Example Terrorist attacks could be planned or completely disorganized, but it is always good to presume that any terror attacks have organized traps for the first responders. This aspect calls for extra carefulness for who should or should not take the first response step (Weiss, 2001, pg.117). First responders do not always find their actions rewarding. In some cases, terrorist ambush those willing to take first action by shooting at them, planting bombs in unexpected locations, trapping them within buildings, or making them appear like they were among the terror attackers among other dangers and traps. Some terrorist attacks however may not need to be planned for the dangers to be high. Attacks made using radiological dispersion devices are generally dangerous for first responders who may lack the expertise to detect harmful radiations (Runge, 2009, pg. 407). The invisible radiations in this regards could be part of the dangers and traps arising from a well-planned terrorist attack of such kind. In the case of terrorist attacks, hospitals within the locality are likely to be interrupted since they are faced with the obligation of accommodating the injured victims. In order for hospitals to avoid adverse interruptions, they should prepare a disaster plan to prepare for major influxes of injured individuals after terrorist attacks. This plan for enhancing preparedness should include an effective plan for handling the deceased especially in worse case situations (Lowe & Hummel, 2014, pg. 211). The preparedness plan may include contingencies that would encompass the hospital’s strategy. The hospital can also adopt the plan to include further actions such as handling victims of terrorism attack earlier even before arriving at the hospital. This could be done like the case of many hospitals that have already implemented plans for handling victims of
