Sound symbolism facilitates interspecies communication between humans and domestic dogs (Canis familiaris)
No full textAbstract The evolution of human communication likely centred, in part, on shared intuitions about the mapping of sound to meaning. These sound-meaning intuitions, known as sound symbolism, can be seen for example in the bouba-kiki effect, where nonsense words carry inherent meaning about their likely referents (here, rounded vs. angular objects respectively). In our paper we suggest for the first time that sound symbolism can afford successful interspecies communication between humans and animals in certain circumstances. Over four investigations, including replications, we show that humans use sound symbolism significantly and pervasively to attempt to convey meaning to domestic dogs (Canis familiaris), specifically, by exploiting vocal prosody to signal elevation in space. In Study 1 we analysed recordings of amateur dog owners commanding their dogs to move upwards (e.g., “stand”) or downwards (e.g., “down”), finding higher mean pitch (fundamental frequency, f 0 ) in the former versus the latter. In Studies 2 and 3a, we replicated this in competitive dog owners, both in self-report, and in acoustic voice-analyses recorded in competition. In addition, professionals also used further sound symbolism beyond amateurs, in their commands for the dog to “sit” (using higher pitch to denote sit up vs. sit down). Finally, in Study 3b, we demonstrate that sound symbolism appears to be mutually understood by dogs in certain useful circumstances. Dogs were faster to enact “down” commands with prosodic sound symbolism, compared to without, demonstrating that sound symbolism may sometimes underlie successful inter-species communication
Polly H. Carder Collection on George F. Root
No full textGeorge Frederick Root (1820-1895) was an American songwriter and music educator. He is perhaps best known for his song "The Battle Cry of Freedom," which was written and rose to popularity during the U.S. Civil War. The Polly H. Carder Collection on George F. Root contains original published scores and songbooks from the period 1852-1907 and photocopied scores collected by Polly H. Carder, author of the book George F. Root, Civil War Songwriter: A Biography. The collection also contains a short article, "The Last Days of George F. Root," written by Root's daughter, Clara Louise Burnham

Root developmental responses to heterogeneous water and nitrogen supply
No full textBetter understanding of the interaction between the soil physical properties determining water and nitrate availability and the root proliferation and gene expression components of nutrient acquisition could contribute to food security, but may have been limited by experimental systems.
A sand rhizotron system was developed to investigate Arabidopsis (Arabidopsis thaliana) root responses to altered water and nitrate supply as manipulated by soil physical properties. When this system was compared to agar, root disparities were explained by differences in hydraulic properties, highlighting the importance of the soil physical component. The sand rhizotron system was adopted to quantify root proliferation and gene expression responses to altered water and nitrate availability in wild-type and selected mutant seedlings.
In the sand rhizotron system, primary root length and lateral root density were oppositely regulated by water availability, but similarly independent of nitrate supply. The expression of the nitrate transporter AtNRT2.1 and the aquaporin AtPIP2.2 was coordinated across all treatments. Their concentration-dependent hydraulic regulation was confirmed for AtNRT2.1 by in situ imaging of a Green Fluorescent Protein reporter line. AtNAR2.1 and AtNRT2.1 expression demonstrated independent responses to water and nitrate availability despite the requirement of AtNAR2.1 for AtNRT2.1 uptake function. Root proliferation responses to water availability under high (10.0 mM) nitrate were lost in the atnar2.1 mutant and coincided with altered hormone-associated gene (AtEIN2, AtABI4 and AtIPT5) expression. Root proliferation and AtNAR2.1 responses to water availability under high (10.0 mM) nitrate required AtPIP2.2. The coordination of root proliferation and gene expression responses to altered water and nitrate availability is proposed, that includes novel roles for AtNRT2.1, AtNAR2.1 and AtPIP2.2

Range Unit Root (RUR) Tests: Robust against Nonlinearities, Error Distributions, Structural Breaks and Outliers
No full textSince the seminal paper by Dickey and Fuller in 1979, unit-root tests have conditioned the standard approaches to analysing time series with strong serial dependence in mean behaviour, the focus being placed on the detection of eventual unit roots in an autoregressive model fitted to the series. In this paper, we propose a completely different method to test for the type of long-wave patterns observed not only in unit-root time series but also in series following more complex data-generating mechanisms. To this end, our testing device analyses the unit-root persistence exhibited by the data while imposing very few constraints on the generating mechanism. We call our device the range unit-root (RUR) test since it is constructed from the running ranges of the series from which we derive its limit distribution. These nonparametric statistics endow the test with a number of desirable properties, the invariance to monotonic transformations of the series and the robustness to the presence of important parameter shifts. Moreover, the RUR test outperforms the power of standard unit-root tests on near-unit-root stationary time series; it is invariant with respect to the innovations distribution and asymptotically immune to noise. An extension of the RUR test, called the forward?backward range unit-root (FB-RUR) improves the check in the presence of additive outliers. Finally, we illustrate the performances of both range tests and their discrepancies with the Dickey?Fuller unit-root test on exchange rate series.Publicad
