Results and Discussion Table 1 (top) shows the root mean square error (RMSE) between the three tests for different numbers of topics. These results show that all three tests largely agree with each other but as the sample size (number of topics) decreases, the agreement decreases. In line with the results found for 50 topics, the randomization and bootstrap tests agree more with the t-test than with each other. We looked at pairwise scatterplots of the three tests at the different topic sizes. While there is some disagreement among the tests at large p-values, i.e. those greater than 0.5, none of the tests would predict such a run pair to have a significant difference. More interesting to us is the behavior of the tests for run pairs with lower p-values. ≥ Table 1 (bottom) shows the RMSE among the three tests for run pairs that all three tests agreed had a p-value greater than 0.0001 and less than 0.5. In contrast to all pairs with p-values 0.0001 (Table 1 top), these run pairs are of more importance to the IR researcher since they are the runs that require a statistical test to judge the significance of the per- formance difference. For these run pairs, the randomization and t tests are much more in agreement with each other than the bootstrap is with either of the other two tests. Looking at scatterplots, we found that the bootstrap tracks the t-test very well but shows a systematic bias to produce p-values smaller than the t-test. As the number of topics de- creases, this bias becomes more pronounced. Figure 1 shows a pairwise scatterplot of the three tests when the number of topics is 10. The randomization test also tends to produce smaller p-values than the t-test for run pairs where the t- test estimated a p-value smaller than 0.1, but at the same time, produces some p-values greater than the t-test’s. As Figure 1 shows, the bootstrap consistently gives smaller p- values than the t-test for these smaller p-values. While the bootstrap and the randomization test disagree with each other more than with the t-test, Figure 1 shows that for a low number of topics, the randomization test shows less noise in its agreement with the bootstrap com- Figure 1: A pairwise comparison of the p-values less than 0.25 produced by the randomization, t-test, and the bootstrap tests for pairs of TREC runs with only 10 topics.

Informal Discussions The employee's concerns will be presented orally by the employee to the appropriate supervisor. Every effort shall be made by all concerned in an informal manner to develop an understanding of the facts and the issues in order to create a climate which will lead to resolution of the problem. If the employee is not satisfied with the informal discussion(s) relative to the matter in question, he/she may proceed to the formal grievance procedure.

SUSPENSION AND DISCIPLINE 29.01 When an employee is suspended or discharged from duty, the Employer undertakes to notify the employee in writing, with a copy to the Association, of the reason for such suspension or discharge. The Employer shall endeavour to give such notification at the time of suspension or discharge.
Required Disclosures If Dell is required by a government body or court of law to disclose any Customer Content, Dell will provide You with notice and a copy of the demand as soon as practicable, unless prohibited by applicable law. Dell will take reasonable steps at Your expense to contest any required disclosure if requested by You.
Informal Discussion If an employee has a problem relating to a work situation, the employee is encouraged to request a meeting with his or her immediate supervisor to discuss the problem in an effort to clarify the issue and to work cooperatively towards settlement.
Compelled Disclosures If the Receiving Party or any of its Representatives is compelled by applicable Law to disclose any Confidential Information then, to the extent permitted by applicable Law, the Receiving Party shall: (a) promptly, and prior to such disclosure, notify the Disclosing Party in writing of such requirement so that the Disclosing Party can seek a protective order or other remedy or waive its rights under Section 6.3 of these General Terms; and (b) provide reasonable assistance to the Disclosing Party, at the Disclosing Party’s sole cost and expense, in opposing such disclosure or seeking a protective order or other limitations on disclosure.
