Visual Conditions

The purpose of this study was to examine the effects of aural, visual, and combined aural/visual conditions on the emotional response to music and dance of musicians and nonmusicians. Measurement was recorded on the perceived amount of artistic tension occurring in three stimuli. Subjects were randomly assigned to three experimental groups: aural-only, visual-only, and combined aural/visual. Stimuli used for the experimental conditions were three dance excerpts. Subjects were asked to indicate degrees of perceived artistic tension by manipulating a Continuous Response Digital Interface (CRDI) dial during experimental conditions. Additional data were gathered using a questionnaire. Results indicated no significant differences in perceived artistic tension between musicians and nonmusicians. Additionally, no differences were found in perceived artistic tension among the responses to the three experimental conditions. Subjects responded similarly regardless of whether they had previously considered the existence of artistic tension. A significant difference occurred in subject response to each of the three stimuli.

The purpose of this study was to investigate the effect of wearing earplugs on classical musicians’ pitch perception across three experimental conditions: no earplugs, foam earplugs, and Etymotic earplugs. Participants were graduate and undergraduate music majors attending a large school of music in the southeastern United States ( N = 72). Participants adjusted the pitch of five complex stimulus tones (C#4, C#5, C#3, G#4, and F#3) using a continuous response digital interface until they believed the interval was in tune with an oboe (C#4) reference tone. Participants tended to tune flat when the stimulus tone was presented flat and to tune sharp when it was presented sharp across all three earplug conditions. Overall cent deviation in tuning responses showed that in both directional and absolute deviation analyses, listeners were most accurate when tuning without earplugs, then when using Etymotic earplugs, and least accurate with foam earplugs. Significant differences, however, were limited to specific intervals and in magnitudes not likely to be perceived. Although more research is needed, the use of Etymotic earplugs may provide valuable protection against noise-induced hearing loss with negligible effects on pitch perception. Implications for musicians and recommendations for future research are discussed.

Level Of Processing

An experiment is described which attempts to derive quantitative indicators regarding the potential relevance predictability of the intermediate stimuli used to represent documents in information retrieval systems. In effect, since the decision to peruse an entire document is often predicated upon the examination of one »level of processing« of the document (e.g., the citation and/or abstract), it became interesting to analyze the properties of what constitutes »relevance«. However, prior to such an analysis, an even more elementary step had to be made, namely, to determine what portions of a document should be examined.An evaluation of the ability of intermediate response products (IRPs), functioning as cues to the information content of full documents, to predict the relevance determination that would be subsequently made on these documents by motivated users of information retrieval systems, was made under controlled experimental conditions. The hypothesis that there might be other intermediate response products (selected extracts from the document, i.e., first paragraph, last paragraph, and the combination of first and last paragraph), that would be as representative of the full document as the traditional IRPs (citation and abstract) was tested systematically. The results showed that:1. there is no significant difference among the several IRP treatment groups on the number of cue evaluations of relevancy which match the subsequent user relevancy decision on the document;2. first and last paragraph combinations have consistently predicted relevancy to a higher degree than the other IRPs;3. abstracts were undistinguished as predictors; and4. the apparent high predictability rating for citations was not substantive.Some of these results are quite different than would be expected from previous work with unmotivated subjects.

© 2020 Elsevier Inc. The Taylor Aggression Paradigm (TAP) is widely used to measure reactive aggression in laboratory settings. While modified versions (mTAPs) with various stimulus characteristics (shocks, noise, pressure, heat) have already been established, a modified version with monetary stimuli has only been introduced very recently. In this experiment, 209 young healthy participants (104 males, 105 females) completed a mock Competitive Reaction Time Task (CRTT) with a fictional opponent with preprogrammed 40 win and 60 lose trials. In lose trials, participants were provoked by subtracting a low (0–20 euro cents), medium (30–60 cents) or high (70–90 cents) amount of money from their fictitious account. Provocation stimuli were either presented randomly or in a fixed sequence (experimental conditions). In contrast to a random sequence, the fixed sequence was generated by repeating trials from the same provocation category in series of three. Linear mixed models (LMMs) considering aggression trajectories revealed significant effects of provocation (low, medium, high) and trait aggression (K-FAF) on reactive aggression. Men showed significantly higher reactive aggression levels than women. In regard to provocation sequence, we found no significant difference in reactive aggression between the random vs. fixed stimulus sequences. The findings provide new evidence supporting the view that the monetary mTAP is able to induce as well as capture reactive aggression in the laboratory. Additionally, we found no advantage of a fixed sequence as the level of reactive aggression in a given trial appeared to be mainly predicted by the preceding provocation trial.

There are situations in which intraradicular retainers have to be removed and replaced. The objective of this research was to evaluate the apical seal after the removal of a custom cast post and core with a carbide bur or with an ultrasound apparatus. Twenty five roots of extracted human incisors were used. They were endodontically treated and prepared to receive the posts. The posts and cores were cast with 2 types of dental alloys, CuAlZn and PdAg, and were cemented with zinc phosphate cement. After 24 hours, they were removed using the two above mentioned techniques. Then, the roots had their external surface made impermeable by two layers of cyanoacrylate adhesive, leaving only the cervical area for dye penetration. The teeth were immersed in rhodamine for 24 hours. They were then cut and observed under an optical microscope and analyzed with appropriate software (Imagelab). The results were submitted to ANOVA, and they evidenced that, regarding the alloy factor, PdAg posts presented a larger mean infiltration value (2.23 ± 0.48 mm) as compared to the posts made of CuAlZn (1.39 ± 0.48 mm) (p = 0.025). Regarding the technique factor, there was no significant difference (p = 0.9) between the removal of the intraradicular retainer using ultrasound (1.99 ± 0.62 mm) or using a rotating cutting instrument (1.62 ± 0.62 mm). Under these experimental conditions, it was possible to conclude that the degree of apical leakage was directly related to the alloy type, and it was present in both techniques used.

ABSTRACT: This work aimed to evaluate the effect of platelet-rich plasma (PRP) on advancement skin flaps in dogs regarding improvement of vascularization, with focus on increasing its viable area, since there are reports that it is a potential angiogenesis stimulator. The experimental group was composed of eight adult bitches, in which two advancement skin flaps were made in the ventral abdominal region. No product was applied in the control flap (CF), while PRP was used in the contralateral flap, called treated flap (TF). The areas were clinically evaluated every two days until the 7th postoperative day regarding skin color and presence of necrosis. At 10 days, both flaps were removed and submitted to histological examination and blood vessel morphometry. The vessels counted in each group were statistically analyzed by the F-test at 1% probability. Results showed no significant difference in macroscopic changes in the wound, or CF and TF vascularization, thus suggesting that PRP gel did not improve advancement skin flap angiogenesis in bitches under the experimental conditions in which this research was developed.

Abstract. Atmospheric furan is a primary and secondary pollutant in the atmosphere, and its emission contributes to the formation of ultrafine particles and ground-level ozone. We investigate the effects of NOx level and humidity on the formation of secondary organic aerosol (SOA) generated from the photooxidation of furan in the presence of NaCl seed particles. The particle mass concentration and size distribution were determined with a scanning mobility particle sizer (SMPS). SOA mass concentration and yield were determined under different NOx and humidity levels. A significant difference is observed both in the SOA mass concentration and SOA yield variation with the initial experimental conditions. Six organic products were identified in the collected SOA by electrospray ionization exactive orbitrap mass spectrometry (ESI-Exactive-Orbitrap MS). The –COOH, –OH, –C=O and NO2 functional groups were assigned in the FTIR spectra and used as the indicator for the mechanism inference. In addition, O3 formation was also observed during the furan-NOx-NaCl photooxidation. Based on the MS analysis, the reaction mechanism was proposed to follow the RO2+NO pathway. A significant amount of carbonyl-rich products was detected in the SOA products from the photooxidation of furan. The SOA mass concentration and yield increase with increasing humidity, because higher aerosol liquid water content brings more aqueous phase reactions. The present study demonstrates the effect of NOx and humidity on SOA formation during the furan-NOx-NaCl photooxidation. Furthermore, the results illustrate the importance of studying SOA formation over a comprehensive range of environmental conditions. Only such evaluations can induce meaningful SOA mechanisms to be implemented in air quality models.

Rinsing rat femoral arteries with various fluids in experimental conditions similar to those in clinical practice was found to have deleterious effects on the intimal and medial layers of the vessels. No statistically significant difference was found between the effects of Ringer’s lactate and normal saline. Heparinized saline produced significantly less damage to the medial layer and less platelet cell deposition. Lignocaine 2% was found to be extremely damaging to the whole vessel wall, and highly thrombogenic. Nevertheless, all the arteries in each group remained patent 4 days after rinsing.

The purpose of this study was to examine the effect of teaching setting [peer versus practicum] and self-evaluation tools [Continuous Response Digital Interface (general) versus behavioral checklist (specific)] on the development of teacher intensity behaviors among preservice elementary education majors enrolled in a music methods course. Subjects were divided into four treatment groups and completed a pretest and posttest and four treatment lessons. Analyses indicated that teaching setting and self-evaluation did not have a differential effect on teacher intensity. All subjects made significant gains from pretest to posttest, with differences among lessons. Comparative analyses indicated subjects rated themselves higher than did experts. An attitude survey indicated that subjects who taught children rated the course higher than subjects who taught their peers, whereas subjects who completed general self-evaluations rated the course higher than did subjects who completed specific self-evaluations.

High School Musicians

Undergraduate college music majors, high school musicians in performance groups, and sixth-grade students in eight sites across the United States listened to brief excerpts of music from early contemporary compositions, popular classics, selections in the Silver Burdett/Ginn elementary music education series, and current crossover jazz recordings. Each of the classical categories had a representative keyboard, band, choral, and orchestral excerpt. Self reports of knowledge and preference were recorded by the Continuous Response Digital Interface (CRDI) while subjects listened to excerpts. Instrumental biases were found among high school and college musicians' preferences for relatively unfamiliar classical music. College music majors' preferences, in general, were less “own-instrument-based” than were those of high school musicians. In addition, the results suggest training broadens receptivity within and across music genres. There seems, however, to be no predictable connection between the degree to which one “knows ” an excerpt and preference for the excerpt.

Long-term repeated administration of isoproterenol (lPR) 2 mg/100 g bw, once daily for ten days, resulted in morphological changes in the intercellular junctions of rat submandibular glands, which were investigated by means of the freeze fracture technique. A significantly increased number of tight-junctional strands was present. These junctional strands extended much deeper toward the basal membrane than those in normal acinar cells. The basal frontier strands that branched from the networks of tight junctions were elongated and had either free-endings or terminal loops, which were more frequently observed in the IPR-treated acinar cells than in untreated acinar cells. Some of the strands of tight junctions were connected to small gap junctions. The diameters of gap junctions were not significantly different from those of control acinar cells. However, smooth areas devoid of particles were found intermingling with the usual packed particles in irregularly shaped small gap junctions. There was no significant difference between the desmosomes of IPR-treated and untreated acinar cells, in terms of either morphology or distribution. These changes in junctional morphology in the IPR-treated acinar cells resemble those seen in salivary glands during development, and in some experimental conditions including tumorous changes.
