Musical expression is often dependent upon accentuation, yet there is little research in the perception of dynamic accent in music and its relationship to intensity just noticeable differences (JNDs). This experiment estimated relationships among (a) accent limen (AL), (b) difference limen (DL), and (c) the ages of the nonmusician female subjects (N = 51). The AL was the intensity increment producing 80 % correct criteria in subjects' perceptions of single accented tones embedded xvithin seven-tone isochronous series. The unaccented tones were identical-timbre 87-dB(A) digitally produced snare drum sounds. The DL was the intensity difference in tone pairs that produced a 75% correct criterion. The relationship between AL and DL was not significant [F(1, 48) = 5.505, p = .197]. The relationship between AL and age was significant [F(1, 48) = 5.732, p = .021], suggesting that the amount of intensity change required for perception of intensity accentuation in musical set-I tings (especially by children) should be larger than the DL.

AbstractTRMM satellite 3B42 rainfall estimates for 133 landfalling tropical cyclones (TCs) over China during 2001–15 are used to examine the relationship between TC intensity and rainfall distribution. The rain rate of each TC is decomposed into axisymmetric and asymmetric components. The results reveal that, on average, axisymmetric rainfall is closely related to TC intensity. Stronger TCs have higher averaged peak axisymmetric rain rates, more averaged total rain, larger averaged rain areas, higher averaged rain rates, higher averaged amplitudes of the axisymmetric rainfall, and lower amplitudes of wavenumbers 1–4 relative to the total rainfall. Among different TC intensity change categories, rapidly decaying TCs show the most rapid decrease in both the total rainfall and the axisymmetric rainfall relative to the total rain. However, the maximum total rain, maximum rain area, and maximum rain rate are not absolutely dependent on TC intensity, suggesting that stronger TCs do not have systematically higher maximum rain rates than weaker storms. Results also show that the translational speed of TCs has little effect on the asymmetric rainfall distribution in landfalling TCs. The maximum rainfall of both the weaker and stronger TCs is generally located downshear to downshear left. However, when environmental vertical wind shear (VWS) is less than 5 m s−1, the asymmetric rainfall maxima are more frequently located upshear and onshore, suggesting that in weak VWS environments the coastline could have a significant effect on the rainfall asymmetry in landfalling TCs.

It is increasingly realized that hypnosis may be seen from an interpersonal point of view, meaning that it forms part of the relationship between the hypnotist and the subject. From this premise it follows that what goes on in the relationship prior to hypnosis probably has an influence on the hypnosis. Certain of these prior occurences can then be seen as waking suggestionns (however implicitly given) that the subject should behave in a certain way with regard to the subsequent hypnosis. A study was conducted to test the hypothesis that waking suggestions regarding post-hypnotic amnesia are effective. Eighteen female subjects were randomly divided into two groups. The groups listened to a tape-recorded talk on hypnosis in which for the one group amnesia for the subsequent hypnotic experience and for the other group no such amnesia was suggested. Thereafter the Stanford Hypnotic Susceptibility Scale was administered to all subjects. Only the interrogation part of the amnesia item of the scale was administered. The subjects to whom post-hypnotic amnesia was suggested tended to score lower on the amnesia item than the other subjects, as was expected, but the difference between the mean amnesia scores of the two groups was not significant.

Abstract The deviation angle variance (DAV) is a parameter that characterizes the level of organization of a cloud cluster compared with a perfectly axisymmetric tropical cyclone (TC) using satellite infrared (IR) imagery, and can be used to estimate the intensity of the TC. In this study, the DAV technique is further used to analyze the relationship between satellite imagery and TC future intensity over the North Atlantic basin. The results show that the DAV of the TC changes ahead of the TC intensity change, and this can be used to predict short-term TC intensity. The DAV-IR 24-h forecast is close to the National Hurricane Center (NHC) 24-h forecast, and the bias is lower than NHC and other methods during weakening periods. Furthermore, an improved TC intensity forecast is obtained by incorporating all four satellite bands. Using SST and TC latitude as the other two predictors in a linear regression model, the RMSE and MAE of the DAV 24-h forecast are 13.7 and 10.9 kt (1 kt ≈ 0.51 m s−1), respectively, and the skill space of the DAV is about 5.5% relative to the Statistical Hurricane Intensity Forecast model with inland decay (Decay-SHIFOR) during TC weakening periods. Considering the DAV is an independent intensity technique, it could potentially add value as a member of the suite of operational intensity forecast techniques, especially during TC weakening periods.

Category: Hindfoot Introduction/Purpose: The primary aim of this study was to calculate the mean values of three most frequently measured parameters for hindfoot alignment determination in asymptomatic subjects - hindfoot alignment angle (HAA), hindfoot alignment ratio (HAR), and hindfoot moment arm (HMA). The secondary aim was to determine the relationship between HAR and HAA or HMA using statistical methods. Methods: From January 2014 to June 2019, a total of 1128 asymptomatic subjects were enrolled in this study. With the hindfoot alignment view by Saltzman and el-Khoury, HAA, HAR, and HMA were measured to evaluate the degree of hindfoot varus or valgus deviation. All subjects were divided into subgroups according to sex and age (<45 years old vs >=45 years old). Simple linear regression was performed to draw out the regression formula between HAR and HAA or HMA. Results: The mean HAA, HAR, and HMA for all subjects were -4.07+-3.48o, 0.21+-0.15, and -6.12+-5.22 mm, respectively. By comparing subgroups, female subjects >=45 years old showed the largest valgus deviation (-7.08+-6.34o, P=0.001). To predict HAR using HAA or HMA, the regression formulas were ‘HAR= 0.366 + 0.039 × HAA’ and ‘HAR= 0.361 + 0.025 × HMA.’ Conclusion: Under HAA, HAR, and HMA evaluation, the hindfoot alignment for asymptomatic subjects was valgus deviation. Furthermore, the degree of valgus deviation was the largest in female subjects aged 45 years or older. This can be explained as the progression of adult type flat foot deformity with aging.

This paper considers the relationship between design, practice and research in the area of New Interfaces for Musical Expression (NIME). The author argues that NIME practitioner-researchers should embrace the instability and dynamism inherent in digital musical interactions in order to explore and document the evolving processes of musical expression.

This article makes a case for the radical potential of the traditional domestic sitcom as a critical cultural vehicle, challenging hegemonic understandings of the form as conservative. Through a detailed consideration of the BBC’s Some Mothers Do ‘ave ‘em (1973‐78), one of the most popular examples from the 1970s, it points to the series’ critique of the heteronormative intimacies and domestic configurations that are assumed to be at the heart of traditional sitcom, presenting them as a site of disruption and unease rather than one of stability. The article asks how the character of Frank Spencer is defined by domesticity, appropriating a line of enquiry that is traditionally applied to female subjects and femininities. By queering the critical frame in this way, it opens up a fresh approach to the British sitcom elaborated through a variety of inter- and extratextual material, building on recent studies that have begun to explore what a queer perspective might contribute to the understanding of sitcom and its history (Villarejo 2014; Pugh 2018; White 2018; Miller 2019). Furthermore, by uncovering the queer potential of ‘prime-time’ televisual domesticities, this article suggests that prime-time content could occupy far more radical discursive positions than have been assumed, and complicates traditional assumptions around the relationship between television and domesticity.
