an experiment was conducted to study the effects of different concentrations of silver thiosulfate (sts) (0.25, 0.5, 1 and 2 mm), sucrose (2.5, 5, 7.5 and 10 %), humic acid (100, 500, 1000, 5000 and 10000 ppm) and banzyl adenine (5, 10, 20 and 40 ppm) on vaselife of cut ‘tempo’ carnation flowers. the experiment was arranged in a compeletly randomized design. the results of means comparison indi...

Music sometimes improves performance in sustained attention tasks. But the type of music employed in previous investigations has varied considerably, which can account for equivocal results. Progress has been hampered by lack of a systematic database of music varying in key characteristics like tempo and valence. The aims of this study were to establish a database of popular music varying along...

Many studies have revealed the influences of music, and particularly its tempo, on the autonomic nervous system (ANS) and respiration patterns. Since there is the interaction between the ANS and the respiratory system, namely sympatho-respiratory coupling, it is possible that the effect of musical tempo on the ANS is modulated by the respiratory system. Therefore, we investigated the effects of...

BACKGROUND Opportunistic screening for chlamydia in non-clinical settings is becoming more common, but little is known about which settings (or events) offer the best return on investment. We measured the relative efficiency of each screening site and event during the conduct of a chlamydia education and screening outreach program which used a cash incentive to encourage participation (SOC2). ...

The ability to remember tempo (the perceived frequency of musical pulse) without external references may be defined, by analogy with the notion of absolute pitch, as absolute tempo (AT). Anecdotal reports and sparse empirical evidence suggest that at least some individuals possess AT. However, to our knowledge, no systematic assessments of AT have been performed using laboratory tasks comparabl...

The study presented here outlines a procedure for measuring and quantitatively representing the perceptual tempo of a musical excerpt. We also present a method for applying such measures of perceptual tempo to the design of automatic tempo-trackers in order to more accurately represent the perceived beat in music.

Tempo is a logic programming language that has recently been designed with the aim of allowing concurrent programs to be written in a more declarative manner than existing languages. One of the benefits of declarative programming is the potential for systematic derivation of programs — the subject of this paper. Here we present a few transformation rules that can be applied to Tempo programs, a...

In musical performances with expressive tempo modulation, the tempo variation can be modelled as a sequence of tempo arcs. Previous authors have used this idea to estimate series of piecewise arc segments from data. In this paper we describe a probabilistic model for a time-series process of this nature, and use this to perform inference of singleand multi-level arc processes from data. We desc...

For the description of rhythmic content of music signals usually features are preferred that are invariant in presence of tempo changes. In this paper it is shown that the importance of tempo depends on the musical context. For popular music, a tempo-sensitive feature is improved on multiple datasets using analysis of variance, and it is shown that also a tempo-robust description profits from t...

The aim of the present study is to investigate the effects of tempo manipulations in radio commercials, on listeners’ evaluation, cognition and persuasion. Questionnaire scores from 131 young and 130 elderly listeners show effects of tempo manipulation on listeners’ subjective evaluation, but not on their cognitive scores. Tempo effects on persuasion scores are modulated by the listeners’ gener...
