Abstract:

This exploratory study focuses on the relationship between vocal expression, musical structure, and emotion in recorded performances by famous singers of three Schubert songs. Measurement of variations in tempo, dynamics, and pitch showed highly systematic relationships with the music's structural and emotional characteristics, particularly as regards emotional activity and valence. Relationships with emotional activity were consistent across both singers and musical pieces, while relationships with emotional valence were piece-specific. Clear changes in performing style over the twentieth century were observed, including diminishing rubato, an increase followed by a decrease of the use of pitch glides, and a widening and slowing of vibrato. These systematic changes over time concern only the style of performance, not the strategies deployed to express the structural and emotional aspects of the music.

Abstract:

Background: In developing the PB-50 word lists, J. P. Egan suggested five developmental principles, two of which were “equal average difficulty” and an “equal range of difficulty” among the lists (page 963). Egan was satisfied that each of the 20 PB-50 lists had equivalent ranges of recognition performances and that the lists produced the same average performances. This was accomplished in preliminary studies that measured the recognition performance of each word and eliminated words that were always or never correct. In preparing for studies of interrupted words, we needed to know the range of difficulty inherent in the speaker specific NU-6 and Maryland CNC materials we planned to use when those words were not interrupted. There were only a few studies in the literature that touched on the range of difficulty characteristic of the word-recognition materials in common usage. The paucity of this information prompted this investigation whose scope broadened to include the CID W-22, Maryland CNC, NU-6, and PB-50 materials spoken by a variety of speakers. Purpose: The purpose was to evaluate the homogeneity with respect to intelligibility of the words that comprise several of the common word-recognition materials used in audiologic evaluations. Research Design: Both retrospective (10) and prospective (3) studies were involved. Data from six of the retrospective studies were from our labs. The prospective studies involved both listeners with normal hearing for pure tones and listeners with sensorineural hearing loss. Study Sample: The sample sizes for the 13 data sets ranged from 24 to 1,030, with 24 the typical number for listeners with normal hearing. Data Collection and Analysis: The retrospective data were from published studies and archived data from our laboratories. The prospective studies involved presentation of the word-recognition materials to the listeners at a comfortable level. An item analysis was conducted on each data set with descriptive statistics used to characterize the data. Additionally, skewness coefficients were calculated on the distributions of word performances and the interquartile range was used to determine minor and major outliers within each set of 200 words and their component 50-word lists (300 words for the Maryland CNCs). Results: For listeners with normal hearing the majority of performances on the words within a 50-word list were better than the mean performance, which produced negatively skewed distributions with outlier performances in every list. For listeners with sensorineural hearing loss the performances on the words within a 50-word list were evenly distributed above and below the mean performance, which yielded essentially normal distributions with few outliers. There were a few words on which performances were better by the listeners with hearing loss. Conclusions: Every list of word-recognition materials has a few words on which recognition performances are noticeably poorer than performances on the majority of the remaining words. If the intention of an experiment is to evaluate performance at the word level, then identifying these “outliers” becomes a necessity. Although not evaluated in this report, the implications for 25-word lists are they should be based on recognition-performance data and not compiled arbitrarily.

Abstract:

Studies of duration in music performance since the 1980s have focused on the role of duration in the communication of musical structure, namely grouping and metric structure. This article posits a broader view of duration in performance, namely that performers choose durations to facilitate or inhibit listener-performer synchronicity. Listeners who maintain synchronicity are continually rewarded for making accurate predictions of when events will happen, and thus the loss of synchronicity might hazard feelings of frustration or isolation. Performers, by choosing durations that are difficult to predict, can therefore enlist these feelings in dynamic narratives of synchronicity that augment trajectories in the score. The article explores two such narratives, found in seventeen participants’ attempts to synchronize to two idiosyncratic renditions of passages of Chopin’s mazurkas. By ascribing significance not only to the choices of performers and composers but also to how individual listeners attend to those choices, the article aims to widen the circle of agencies ascribed with the ability to affect the meaning of musical works.

Abstract:

This study examined the intrarater and interrater reliability of the Test of Gross Motor Development—3rd Edition (TGMD-3). Participants were 60 Finnish children aged between 3 and 9 years, divided into three separate samples of 20. Two samples of 20 were used to examine the intrarater reliability of two different assessors, and the third sample of 20 was used to establish interrater reliability. Children’s TGMD-3 performances were video-recorded and later assessed using an intraclass correlation coefficient, a kappa statistic, and a percent agreement calculation. The intrarater reliability of the locomotor subtest, ball skills subtest, and gross motor total score ranged from 0.69 to 0.77, and percent agreement ranged from 87 to 91%. The interrater reliability of the locomotor subtest, ball skills subtest, and gross motor total score ranged from 0.56 to 0.64. Percent agreement of 83% was observed for locomotor skills, ball skills, and total skills, respectively. Hop, horizontal jump, and two-hand strike assessments showed the most difference between the assessors. These results show acceptable reliability for the TGMD-3 to analyze children’s gross motor skills.

Abstract:

All too often, critics, historians, and music analysts draw upon the aesthetic and analytic language of composition to describe and account for performed interpretations. This article explores the inequities and challenges that derive from this borrowing of language. Yet a study of Ernst Levy and his recorded performance of Brahms, however, reveals how compositional aesthetics can also be appropriated and repurposed to new creative ends.

Abstract:

The study investigates the aesthetic experience of a dance performance from the perspective of both the dancers and the audience. The audience observed three short custom-made choreographies that were presented live and then watched the recorded versions, and judged them on an instrument designed to measure the aesthetic experience of dance. The choreographies were performed by six dancers. The dancers judged their own performances as well as the recorded versions of the performances. The analyses revealed that the dancers? aesthetic experience of a dance performance is similar when they perform choreography and watch it on video. On the other hand, the audience showed a higher sensitivity to live performance: they judged the live performance higher on all dimensions of aesthetic experience compared to their video presentation.

Abstract:

We measured the postural sway of two trombonists as they each recorded multiple performances of two solo pieces in each of three different expressive styles (normal, expressive, non-expressive). We then measured the postural sway of 29 non-trombonist listeners as they moved their arms and body, “air-conducting” the recorded sound as if to draw out the emotion from the performance (Experiment 1), and of the two trombonists as they played along with the same recorded performances (Experiment 2). In both experiments, the velocity of listeners’ postural sway was more like that of the performer than expected by chance. Listeners entrained more to back-and-forth than to side-to-side sway in Experiment 1 and only to back-and-forth sway in Experiment 2. Entrainment was not due entirely to performer and listener both swaying to the musical pulse in the same way. Listeners in Experiment 1 rated performances as more expressive when they entrained more, suggesting that entrainment enhanced their aesthetic experience of the music. The whole body appears to contribute to unpacking the expressive content of musical communication.

Abstract:

The shapes and performances of the 175 most recently designed sailboards recorded by testers in different sailboard magazines are statistically correlated to establish whether shapes are in fact responsible for performances as claimed by designers and manufacturers. Different shapes are correlated with different aspects of performance, namely up-wind, reach, broad reach, light- wind performance, medium-wind performance, strong-wind performance and jibes. Statistical analysis by means of different stages of multiple regression showed that different shapes of board collectively contributed in some cases to explaining up to 59% of the variance between certain types of performance.

Abstract:

This essay offers an early chapter in the conjoined history of poetry and performance art, literary criticism and performance studies. Beginning in the mid-1950s and with increasing fervor through the 1960s, American poetry lived simultaneously in print, on vinyl, and in embodied performance. Amid this environment of multimedia publicity, an oddly private poetry emerged. The essay locates confessional poetry in the performance-rich context of its birth and interrogates not only its textual voice but also its embodied, performed breath. Focusing on early confessional work by Robert Lowell and Anne Sexton, this essay conducts side-by-side “readings” of printed poems and recorded performances and suggests that confessional refers to an intermedial, print-performance style—a particular logic for capturing personal performances in print form and for breathing performances back out of the printed page.

Abstract:

The purpose of this study was to examine the effect of differentiated performance attire and stage deportment on adjudicators’ ratings of high school solo vocal performances. High school choral students ( n = 153) and undergraduate ( n = 97) and graduate music majors ( n = 32) served as adjudicators ( N = 282). Adjudicators rated recorded solo vocal performances displayed in audio-only and four audiovisual presentation conditions with differentiated combinations of performance attire and stage deportment. Performance quality ratings were affected significantly by soloists’ performance attire and stage deportment and adjudicators’ academic level. Significant two-way interactions were identified: adjudicator gender by academic level for comparisons of performance ratings assigned in four of the five presentation conditions and adjudicator gender by academic level when differentiated attire was isolated from presentation conditions. Adjudicators assigned significantly higher ratings to performances presented in the audio-only condition.

Abstract:

Cues for listeners' assignment of melodic structure are investigated in music performance. Performers' interpretations of musical structure can influence listeners' perceptions, especially when structural relations among musical events are ambiguous. Performances recorded on a computermonitored acoustic piano were compared with each performer's notated interpretations of melody. Small timing changes (20-50 ms) marked performers' melodic intentions; events interpreted as melody (the most important voice) preceded other events in chords (melody lead). The emergence of melody leads was investigated in successive performances of unfamiliar music: melody leads were larger in experts' than in students' performances, but students showed more increase with practice. In additional experiments, performances of the same music with different melodic interpretations displayed the melody lead in different amounts, which subsequently affected listeners' perceptions of melodic intentions. Subtle expressive cues in music performance arise from individual interpretations and can aid listeners in determining musical structure.

Abstract:

WE INVESTIGATED PEOPLES' ABILITY TO ADAPT TO THE fluctuating tempi of music performance. In Experiment 1, four pieces from different musical styles were chosen, and performances were recorded from a skilled pianist who was instructed to play with natural expression. Spectral and rescaled range analyses on interbeat interval time-series revealed long-range (1/f type) serial correlations and fractal scaling in each piece. Stimuli for Experiment 2 included two of the performances from Experiment 1, with mechanical versions serving as controls. Participants tapped the beat at ¼¼- and ⅛⅛-note metrical levels, successfully adapting to large tempo fluctuations in both performances. Participants predicted the structured tempo fluctuations, with superior performance at the ¼¼-note level. Thus, listeners may exploit long-range correlations and fractal scaling to predict tempo changes in music.

Abstract:

Conventional management of sweet pepper is based on farming practices characterized by the use of chemicals with harmful environmental impact. In order to investigate innovative production, research was carried out in order to assess the effects of two pepper cultivars (‘Brillant’ and ‘Yolo Wonder’) in combination with four farming systems (Conventional control-C; Conventional with microorganism-enriched fertilization-CMF; Organic control-O; Organic with microorganism-enriched fertilization-OMF) on plant physiological parameters, yield and fruit quality. Conventionally grown plants showed higher values of assimilatory pigments and of photosynthetic rate compared to the Organically ones. The CMF resulted in the highest early and total yield, followed by the OMF, due to higher fruit number. Higher values of carotenoids, ascorbic acid and α-tocopherol were recorded in ‘Yolo Wonder’ red fruits compared to ‘Brillant’ yellow berries. The highest total polyphenols concentration was recorded under the CMF, whereas OMF resulted in the highest flavonoids concentration and antioxidant activity.

Abstract:

AbstractThis essay explores the multiple histories, traditions, and authorities present in more than 200 recorded performances of “Body and Soul.” The early recordings (dozens of them from 1930 alone) demonstrate both enormous variety and distinct British and American performance patterns, but few of these innovations survive beyond 1940. Coleman Hawkins's version from 1939, and not the original sheet music or early performance history, set a standard key (D-flat—even for singers!) and a slower standard tempo (quarter = 90, although later it became even slower). Charlie Parker and others in the 1940s, however, were influenced by the Chu Berry and Roy Eldridge recording of 1938, which introduced a “jump” chorus widely reproduced for two decades. Billie Holiday determined which set of lyrics would be sung, but not the form in which they would occur. John Coltrane and McCoy Tyner's new modal approach in 1960 created both direct imitators and also a new tradition of trying to neutralize the harmonic complexity of the tune, which Hawkins had so carefully exploited. This study asks whether a more African and less European model of jazz tunes might reveal a less fixed and more complex notion of a musical work that includes orally preserved and recorded innovations and performance traditions. This research also explores how the record itself, as a physical object, has become an authority.

Abstract:

Abstract Congestive heart failure (CHF) occurs when the heart is unable to provide sufficient pump action to maintain blood flow to meet the needs of the body. Early diagnosis is important since the mortality rate of the patients with CHF is very high. There are different validation methods to measure performances of classifier algorithms designed for this purpose. In this study, k-fold and leave-one-out cross-validation methods were tested for performance measures of five distinct classifiers in the diagnosis of the patients with CHF. Each algorithm was run 100 times and the average and the standard deviation of classifier performances were recorded. As a result, it was observed that average performance was enhanced and the variability of performances was decreased when the number of data sections used in the cross-validation method was increased.

Abstract:

Experiments were conducted to evaluate the efficacy of different micronutrients and fungicides against Alternaria brassicae and Alternaria blight on growth and yield contributing attributes of mustard. Among the treatments, T6 showed the highest performance against Alternaria blight in terms of disease incidence. The lowest leaf infection (9.9%), leaf area diseases (2.5%), pod infection (9.3%) and number of spots per pod (0.6) were recorded in T6. Highest leaf infection (56.1%), diseased leaf area (18.31%), pod infection (42.7%) and number of spots per pod (1.9) were recorded in control. The highest yield (1086.0 kg/ha), germination percentage (99.1) and the lowest seed infection (6.5%) of harvested seeds were obtained from the T6, whereas lowest from T1. The performances of micronutrients were better than control but the performances of micronutrients did not differ significantly when it was used in combination with fungicides.

Abstract:

This study was designed to examine whether the presence of excellent or poor ensemble performances would influence the ratings assigned by ensemble members to conductors who demonstrated highly expressive conducting. Two conductors were videotaped conducting one of two excerpts from an arrangement of Frank Ticheli’s Loch Lomond. These videos subsequently were duplicated and synchronized with either excellent or poor performances that previously had been recorded with a university wind ensemble. To determine whether identical conducting performances would be evaluated differently on the basis of excellent or poor ensemble performance, college band, choir, and orchestra members ( N = 120) viewed each of the four 1-minute excerpts and rated conductor expressivity and ensemble performance quality on 10-point Likert-type scales and provided one brief written comment about each video. Results indicated that ensemble performance quality significantly affected ratings of conductor expressivity ( p < .001). However, the effect size was modest (partial η2 = .29). Participants’ written comments were directed most frequently to the conductor in the excellent-performance condition and to the ensemble in the poor-performance condition.

Abstract:

This study deals with the acoustical factors liable to account for expressiveness in clarinet performances. Mechanical and expressive performances of excerpts from Bach's Suite No. II and Mozart's Quintet for Clarinet and Strings were recorded. Timbre, timing, dynamics, and pitch descriptors were extracted from the recorded performances. The data were processed using a two-way analysis of variance, where the musician's expressive intentions and the note factors were defined as the independent variables. In both musical excerpts, a strong effect of the expressive intention was observed on the timbre (attack time, spectral centroid, odd/even ratio), timing (intertone onset intervals) and dynamics (root mean square envelope) descriptors. The changes in the timbre descriptors were found to depend on the position of the notes in the musical phrases. These results suggest that timbre, as well as timing and dynamics variations, may mediate expressiveness in the musical messages transmitted from performers to listeners.

Abstract:

This study investigated the effects of fatigue on performance quality induced by a prolonged musical performance. Ten participants prepared 10 min of repertoire for their chosen wind instrument that they played three times consecutively. Prior to the performance and within short breaks between performances, researchers collected heart rate, respiratory rate, blood pressure, blood lactate concentration, rating of perceived exertion (RPE), and rating of anxiety. All performances were audio recorded and later analysed for performance errors. Reliability in assessing performance errors was assessed by typical error of measure (TEM) of 15 repeat performances. Results indicate all markers of physical stress significantly increased by a moderate to large amount (4.6 to 62.2%; d = 0.50 to 1.54) once the performance began, while heart rate, respirations, and RPE continued to rise by a small to large amount (4.9 to 23.5%; d = 0.28 to 0.93) with each performance. Observed changes in performance between performances were well in excess of the TEM of 7.4%. There was a significant small (21%, d = 0.43) decrease in errors after the first performance; after the second performance, there was a significant large increase (70.4%, d = 1.14). The initial increase in physiological stress with corresponding decrease in errors after the first performance likely indicates “warming up,” while the continued increase in markers of physical stress with dramatic decrement in performance quality likely indicates fatigue. Musicians may consider the relevance of physical fitness to maintaining performance quality over the duration of a performance.

Instead of re-tracing the frequently discussed relationship between the original performance and its documentation, this interview focuses on the experience of performance from the document and the implications these omnipresent encounters with performance documents have for the ways in which we access the past.

Abstract:

The heart is considered the most important organ of our body that controls the circulation of blood throughout the body. Measured heartbeat signals can be further analyzed in order to know the health condition of a person. The challenge of ECG signal measurement and analysis is how to remove the noises imposed on the signal that is interfered from many different sources, such as internal noise in sensor devices, power line interference, muscle activity, and body movements. This paper implemented wavelet transform to reduce the noise imposed on the ECG signal to get a closely actual heart signal. ECG data used in this research are three digitized recorded ECG data obtained from MIT-BIH Arrhythmia Database. The first step is generating the noisy ECG signal as the input system by adding 1W WGN signal into the original ECG signal. Then DWT is applied to extract the noisy ECG signal. Some DWT’s parameters, threshold selection (rule, type, rescaling), decomposition level, and desired wavelet family are varied to get the best denoised output signal. All results are recorded to be compared. Based on the results, the best DWT parameter for ECG signal denoising is obtained by Symlet wavelet when the decomposition level is set to 3, with soft thresholding, in rigrsure thresholding rule.

Abstract:

AbstractRobert Ashley's opera Perfect Lives was conceived for the medium of television and first broadcast (by the UK's Channel 4) in 1984. Partly for this reason, and also for other factors (the apparently necessary involvement of Ashley himself as narrator; the absence of a complete, fully notated score) the work has received very few live performances. In 2011 the New York City-based performance collective Varispeed reconceived the work as a day-long, site-specific event, following Ashley's available notations and recorded performances in broad outline but departing from them in creative ways. In this article Varispeed founding member Gelsey Bell describes the working processes and decision-making that informed the collective's approach to this experimental classic.

Abstract:

Abstract This paper deconstructs how religious musical eulogies, as the most important discursive practices of Shi’a rituals (Ghaffari 2019), were used as “war songs” serving to construct the Iranian national identity during the 1980–1988 Iraq-Iran war. These musical practices (in)formed the wider ideological and persuasive rhetoric of Iranians. In this paper, I analyse the textual and musical features of the audio-recorded versions of ten well-known war songs. The Discourse-Historical Approach (Reisigl and Wodak 2016) is used to analyse the discursive strategies and persuasive rhetorical tools within the lyrics. I draw on Machin (2010), Machin and Richardson (2012) and van Leeuwen (1999) to analyse various features of voice and the modality of sounds. This paper concludes that, by reflecting the power of religious discourse in the non-religious and highly nationalistic occasion of war, Iranian war songs were inspired by the religious eulogies in encouraging the Iranian nation to attend the war fronts.

Abstract:

Most notated forms of music require interpretation of loosely-defined score instructions. For music ensembles, coordinating a shared interpretation in which each performer plays a complementary role can be challenging, especially if performers have already established their own individual interpretations. This study aimed to identify the patterns of behavior that distinguish performance in collaborative and solo conditions. We tested the hypothesis that highly skilled pianists would be motivated to create more expressively variable and divergent interpretations in the collaborative duet setting than when performing solo. Pianists recorded solo and duet performances of a new piece following individual rehearsal. MIDI and head motion data were assessed. Contrary to expectations, duet performances were less expressively variable than solo performances and no more or less prototypical; indeed, prototypicality increased with years of training. Leader–follower relationships in note timing emerged, with primos tending to take the lead. Pianists moved less during duet performances, and more smoothly. Coordination in head acceleration patterns also emerged during duet performances. Our findings show how performers’ intent to collaborate encourages more communicative styles of head movement and a conservative or protective style of playing that prioritizes coordination over creativity.

Full text

Abstract:

songs that are not notated but transmitted through live performance are of particular interest for the psychological study of the stability of tempo across multiple performances. While experimental research points to highly accurate memory for the tempi of well-known recorded music, this study asks whether there is any evidence of absolute tempo in a performance tradition that does not draw on such reference recordings. Fifty-four field recordings of performances of one Aboriginal dance-song, Djanba 14, were analyzed. Results showed that over a span of 34 years, performance tempi deviated positively or negatively, on average, by 2%. Such small tempo variation is similar to JND thresholds to discriminate the tempi of isochronous sequences. Thirty-five field recordings of another song from the same repertory, Djanba 12, deviated in tempi by an average of 3%. We discuss the musical, psychological, physical, and cultural factors likely to shape such temporal stability.

Full text

Abstract:

Early predictions of cows’ probability of survival to different lactations would help farmers in making successful management and breeding decisions. For this purpose, this research explored the adoption of joint models for longitudinal and survival data in the dairy field. An algorithm jointly modelled daily first-lactation sensor data (milk yield, body weight, rumination time) and survival data (i.e., time to culling) from 6 Holstein dairy farms. The algorithm was set to predict survival to the beginning of the second and third lactations (i.e., second and third calving) from sensor observations of the first 60, 150, and 240 days in milk of cows’ first lactation. Using 3-time-repeated 3-fold cross-validation, the performance was evaluated in terms of Area Under the Curve and expected error of prediction. Across the different scenarios and farms, the former varied between 45% and 76%, while the latter was between 3.5% and 26%. Significant results were obtained in terms of expected error of prediction, meaning that the method provided survival probabilities in line with the observed events in the datasets (i.e., culling). Furthermore, the performances were stable among farms. These features may justify further research on the use of joint models to predict the survival of dairy cattle.

Abstract:

In this paper, the effectiveness of two grid-connected photovoltaic (PV) techniques up of copper indium selenium (CIS) and monocrystalline silicon (m-Si) arrays has been examined. In order to determine whether the technology is suitable for the actual winter and summer climatic conditions in Thoothukudi, Tamil Nadu, the observed and calculated performances have been compared. The final yield, photovoltaic (PV) effectiveness, array yield, performance ratio, and capacity utilisation factor seem to be the variables used to evaluate performance. Using recorded meteorological data at the selected location, PVsyst software predicts both PV systems’ year-round performances. These predictions are then contrasted to the outcomes of the actual measurements. The outcome showed that with a maximal observed performance ratio, both PV systems function marginally better in the winters than those in the summers. The performance indicators of the PV mechanisms are contrary with those of other PV systems with comparable capacities that are located in different places.

Abstract:

This article presents findings from an action research project that investigated instrumental teachers’ strategies for facilitating children’s learning of expressive music performance. Nine teachers and 14 pupils (aged 9–15) participated in this project, which consisted of 10 weeks of teaching. At the beginning and end of this period pupils’ concerts were held and performances were audio-recorded. Participating teachers used various strategies for improving students’ expressive performance: teacher’s enquiry, discussion, explanation of expressive devices, gestures and movements, singing, imagery, modelling, “projected performance” and listening to own recordings. According to teachers these strategies had been useful in lessons. However, analysis of assessments of students’ performances did not show a significant improvement. Four out of five pupils who did improve their expressiveness were taught by teachers who used enquiry and discussion of musical character and instruction about modifying expressive devices. This project influenced the practice of participating tutors as they focused more on teaching expressive performance.

Full text

Abstract:

During the COVID-19 pandemic, theatre groups and companies started massively providing online (filmed) versions of their productions. Theatre performances, live-streamed or recorded, have been shown online before, but mostly as a supplementary strategy, assisting the promotion of a live performance, not as a cultural trend per se, nor to the massive extend it has been happening during the pandemic. However, the consumption of this sort of online content, as this is literally what becomes anything posted on the web’s hypertextual multimedial selves, cannot occur without consideration of the potential implications and side effects. What exactly is it we are watching on our screens, why is it marketed as theatre and performance, and why do we consume it as such? In the paper, the Phelan/Auslander debate is revisited, as this eradication of the distinction between the live and the mediatized may indicate performance’s crucial shift away from independence towards technological, economical and linguistic dependence from mass reproduction. However, before lightheartedly welcoming this hybridity of massively experiencing online performances, which springs out from the collision between live performance (art) and web content (creativity), it is worth considering welcoming first digital performance hybrids emerging within and in between the medial restrictions imposed by the pandemic. These bold, experimental, participatory, ‘transparent’ intermedial forms of expression may prove out to be a source of strength in times of crisis.

Abstract:

Purpose. Attempts to quantify hand movements of surgeons during arthroscopic surgery faced limited progress beyond motion analysis of hands and/or instruments. Surrogate markers such as procedure time have been used. The dimensionless squared jerk (DSJ) is a measure of deliberate hand movements. This study tests the ability of DSJ to differentiate novice and expert surgeons (construct validity) whilst performing simulated arthroscopic shoulder surgical tasks. Methods. Six residents (novice group) and six consultants (expert group) participated in this study. Participants performed three validated tasks sequentially under the same experimental setup (one performance). Each participant had ten performances assessed. Hand movements were recorded with optical tracking system. The DSJ, time taken, total path length, multiple measures of acceleration, and number of movements were recorded. Results. There were significant differences between novices and experts when assessed using time, number of movements with average and minimal acceleration threshold, and DSJ. No significant differences were observed in maximum acceleration, total path length, and number of movements with 10m/s2 acceleration threshold. Conclusion. DSJ is an objective parameter that can differentiate novice and expert surgeons’ simulated arthroscopic performances. We propose DSJ as an adjunct to more conventional parameters for arthroscopic surgery skills assessment.

Abstract:

Abstract Spiral flow-inducing cannula has been shown in previous research to exhibit a considerable effect on flow hemodynamic. However, there is still room for improvement. In this study, several design variations were tested to determine which variants were the best in terms of flow reduction. Computational Fluid Dynamics (CFD) software was used to simulate flow within a spiral flow-inducing cannula with several variations from chamber width and angle differences. The variants were compared against each other by using several flow parameters and a selection method was employed to determine which model was the best. It was found that a variant that has the widest chamber (14 mm) and biggest angle opening (70°) from the chamber to the cannula tube was the best in several parameters, and as such was chosen as the best variant. When compared with the standard straight cannula, the reduction in flow output was recorded to be 30% which is deemed significantly. In conclusion, spiral flow cannula recorded better hemodynamic effects with lower outflow velocity and wall shear stress value.

Abstract:

We examined facial responses to audio-visual presentations of emotional singing. Although many studies have now found evidence for facial responses to emotional stimuli, most have involved static facial expressions and none have involved singing. Singing represents a dynamic ecologically valid emotional stimulus with unique demands on orofacial motion that are independent of emotion, related to pitch and linguistic production. Observers’ facial muscles were recorded with electromyography while they saw and heard recordings of a vocalist’s performance sung with different emotional intentions (happy, neutral, and sad). Audio-visual presentations successfully elicited facial mimicry in observers that were congruent with the performer’s intended emotions. Happy singing performances elicited increased activity in the zygomaticus major muscle region of observers, while sad performances evoked increased activity in the corrugator supercilii muscle region. These spontaneous facial muscle responses occurred within the first three seconds following onset of video presentation indicating that emotional nuances of singing performances can elicit dynamic facial responses from observers.

Abstract:

Abstract From July to November 2019, a study has been carried out in the locality of Ngaoundéré in order to contribute to a better knowledge of exotic hens. For this purpose, 190 improved strain chicks of one day-old with an average weight of 35.49±3.78g were distributed according to the type of feather. They were fed an iso-energetic and iso-proteic feed. Data on phenotype characteristics, growth performance, biometric data and carcass were determined. The main results show that three types of feathering were recorded with 16.4% of hens with bare necks and with feathered pits, 78.1% of hens with feathered pits and 5.5% of hens with normal feathers. The majority of hens were recorded with a single comb (75.3%), round mumps (71.2%), white pits (76.4%), black beaks (47.9%) and brown eyes (75.3%). In terms of zootechnical performance, the highest live weight (1758.00±322.20g) was recorded with naked-necked hens and feathered pits. The highest weekly average weight gain was recorded with yellow eyed hens (111.77±16.63g) followed by bare-necked and feathered pits (107.83±20.06g). Hens expressing the Na and Pti genes showed the best growth performance although carcass yield was not significantly affected by feather type. It was concluded that there is a very high phenotypic diversity in the so-called improved hens. However, despite their great potential, responsible management of this genetic resource should be encouraged in order to avoid genetic erosion of local poultry resources.

Full text

Abstract:

Musicians’ sway during performance seems to be related to musical structure. However, it has yet to be shown that examples of the relationship are not simply due to chance. Progress has been impeded by three problems: the assumption that musical structure is constant across performances; the complexity of the movements; and the inability of traditional statistical tests to accurately model the multilevel temporal hierarchies involved. We solved these problems in a study of the side-to-side postural sway of two trombonists as they each recorded two performances of each of two solo pieces in each of three different performance styles (normal, expressive, non-expressive). The musicians reported their phrasing immediately after each performance by marking copies of the score. We measured the rate and stability (mean line) of recurrence (self-similarity) and assessed the effect of serial position within a phrase, using mixed linear models to model the nesting of phrases within pieces, within performances, across expressive styles and musicians. Recurrence and stability of recurrence changed systematically across the course of a phrase, producing sinusoidal-like and arch-shaped phrasing contours that differed with the performance style and length of phrase. As long suspected, musicians’ expressive movements reflect musical structure.

The aim of this study was to assess the effect of sprouted fenugreek incorporation into the diet of rabbits on their dairy and growth performances. Data from 24 lactations performed by 8 Californian rabbit does were studied. They were divided into 2 homogeneous groups, a control (batch C) having received an ordinary ration and an experimental (batch E) having received the same ration supplemented with sprouted fenugreek. Growth rates of suckling pups were also recorded. Then, Growth performance of 152 young rabbits’ issue from these females was monitored. They were divided into 4 homogeneous groups, one control having received an ordinary diet (batch C) and 3 experimental having received the same diet with substitution of 12%, 15% and 25% (batch E1, E3 and E3) of the concentrate by sprouted fenugreek. The results showed an improvement in the dairy performance of the rabbit does of batch E, with an average peak lactation of 287 g/d vs 236 g/d in batch C (p <0.01). The daily weight gain of suckling pups was better in batch E (13 g/d vs 11.7 g/d; p <0.01). Likewise, the weaned young rabbits of the experimental batches recorded higher growth rates than the control batch (p <0.01). Sprouted fenugreek incorporation into the rabbit’s ration allowed to improve their performances.

The interpreting performance of four students was recorded in the beginning and at the end of their interpreting training. The performances were then analysed by using a modified version of a model of analysis presented by Kopczynski (1980 and 1981). Factors paid attention to in the analysis were equivalence, linguistic competence, linguistic performance and style. The analysis shows that equivalence improves during the period of training but does not achieve the level of equivalence of professional interpreters. In the area of linguistic competence, progress can be noticed as well, but in the area of linguistic performance the students only progress slightly.

Full text

Abstract:

Entoptic landscape and ijereja are both works that can be considered as expanding collections of materials. They explore the spaces between composition, notation, performance and improvisation by considering all of these activities as equally 'performative'. Each work comprises a set of materials that includes scores, fixed media audio and video, recorded live performances, studio-edited performances, and performance strategies. In the case of each piece, materials created in and by previous performances go on to inform future performances of the music. As such, there can be no 'definitive' performance or statement of the works, and nor can they ever be considered finished or bounded. This is how these pieces conceive of music as an iterative process: they are intended as statements of that process. Nicholas Bourriaud (2010) identifies the creative artist as a 'semionaut': one who must navigate between signs and signifiers in order to negotiate, interpret, and create meaning. In the 'work' of music, the composer, performer and listener can all be thought of as semionauts; they take part in the same processes to create and recreate the 'work'. In my own practices I embody and enact all three of these positions, and I seek to blur the boundaries between listening, performing and composing. Contemporary artistic forms in Bourriaud's terms, then, are 'journey forms': they internalise and externalise an experience of movement through the work as a temporal and spatial territory. The music presented here offers an opportunity for the exploration of the journey form as a compositional strategy, a tool for performance and interpretation, and a framework for criticism.

Abstract:

The present study aimed to examine the effects of chronological age and cardiorespiratory fitness (CRF) on cognitive performance and prefrontal cortex activity, and to test the compensation-related utilization of neural circuits hypothesis (CRUNCH). A total of 19 young adults (18–22 years) and 37 older ones (60–77 years) with a high or low CRF level were recruited to perform a working memory updating task under three different cognitive load conditions. Prefrontal cortex hemodynamic responses were continuously recorded using functional near-infrared spectroscopy, and behavioral performances and perceived difficulty were measured. Results showed that chronological age had deleterious effects on both cognitive performance and prefrontal cortex activation under a higher cognitive load. In older adults, however, higher levels of CRF were related to increased bilateral prefrontal cortex activation patterns that allowed them to sustain better cognitive performances, especially under the highest cognitive load. These results are discussed in the light of the neurocognitive CRUNCH model.
