This study found that the agenda-setting hypothesis was supported for the issue of pollution from 1970 to 1990. Real-world conditions and the public agenda were not correlated for this issue. Additionally, despite the overall reduction in pollution, media coverage has increased. However, for waste pollution there was a positive correlation found between the media agenda and real-world conditions.

An error was found in an edge stress coefficient used to calculate stresses in thin windows. This error is present in "Roark's Formulas for Stress and Strain" 7 th and 8 th Edition. The 6 th Edition is correct. This guideline specially discusses a major difference in regards to a coefficient used in calculating the edge stress in "Roark's Formulas for Stress and Strain" 6 th Edition compared to the 7 th and 8 th Editions. In Chapter 10: Flat Plates under "Circular plates under distributed load producing large deflections," Case 3, which is "Fixed and held. Uniform pressure q over entire plate." The coefficient for a fixed edge condition in the 6 th Edition 1 K4 = 0.476 while in the 7 th and 8 th Edition 2 , the coefficient is 1.73 which is significant difference. Fermilab-TM-1380: "Mechanical Safety Subcommittee Guideline for Design of Thin Windows for Vacuum Vessels" 3 references Roark's 6 th edition. TM-1380 is referenced in FESHM FESHM Chapter 5033.1 -Vacuum Window Safety 4 .Case 3 in all three Roark's editions references two documents: APM-56-12: "Bending of Circular
