The absorption spectrum was measured at room temperature from 400 to 900 nm. The decay dynamics of the ⁴F_3/2 multiplet was investigated by measuring the fluorescence lifetime as a function of the sample temperature, and the radiative decay time was derived by extrapolation to 0 K. The stimulated-emission cross-sections of the transitions from the ⁴F_3/2 to the ⁴I_9/2, ⁴I_11/2, and ⁴I_13/2 levels were obtained from the fluorescence spectrum measured at different temperatures, using the Aull-Jenssen technique. The results show consistency with most results previously published at room temperature, extending them over a broader range of temperatures. A semi-empirical formula for the magnitude of the stimulated-emission cross-section as a function of temperature in the 250 K to 350 K temperature range, is presented for the most intense transitions to the ⁴I_11/2 and ⁴I_13/2 levels.23:T408,Unprecedented numbers of negative political advertisements aired in battleground markets during the 2012 primaries, the first presidential campaign since the 2010 Citizens United decision. Grounded in theories of involvement, this investigation parses the influence of partisanship and political expression on the affective effects of negative Super PAC ads. Based on a pretest–posttest design with two experimental conditions and 585 participants, the results indicate both enduring and situational involvement exerted significant main and interaction effects on viewers’ affect toward the general election candidates and the political parties. Driven by Independents who did not engage in political expression, these Super PAC ads evoked significant net decreases in affect toward Mitt Romney and the Republican Party and net increases toward Barack Obama and the Democratic Party. These results suggest enduring and situational involvement moderate the affective effects of negative Super PAC advertising in primary contests.24:T469,While the popular genres of progressive rock and heavy metal have received significant scholarly attention, discussions of the syncretic subgenre of progressive metal are rare. Jonathan Pieslak’s 2007 article on the music of Meshuggah does much to delimit the stylistic boundaries of the subgenre, noting the importance placed by progressive metal bands and their fans on the rhythmic and metrical complexity of the music. Dream Theater, one of the most visible and commercially successful progressive metal bands, however, has received little scholarly attention to this point. The aim of this article is to describe Dream Theater’s unique metrical processes, focusing on a technique that I label the ABAC Additive Metrical Process (ABAC-AMP). The temporally complex examples I analyze in this article—culled from throughout Dream Theater’s decades-long career—are compared with techniques of early minimalist composers. The analysis demonstrates Dream Theater’s “progressive” aesthetic, and it aids in a characterization of the band’s sound as possessing a progressive rock center and a heavy metal periphery.
