Bilinguals Produce Pitch Range Differently in Their Two Languages to Convey Social Meaning.

We investigated whether expression of social meaning operationalized as individual gender identitity and politeness moderated pitch range in the two languages of female and male Japanese-English sequential bilinguals. The bilinguals were resident in either London (UK) or Tokyo (Japan) and read sentences to imagined addressees who varied in formality and sex. Results indicated significant differences in the pitch range of the two languages of the bilinguals, and this was confirmed for female and male bilinguals in London and Tokyo, with the language differences being more extreme in the London bilinguals than in the Tokyo bilinguals. Interestingly, self-attribution of masculine gender traits patterned with within-language variation in the English pitch level of the female bilinguals, whereas self-attribution of feminine gender traits patterned with within-language variation in the English pitch level of the male bilinguals. In addition, female and male bilinguals significantly varied their pitch range in Japanese, but not in English, as a function of the imagined addressees. Findings confirmed that bilinguals produce pitch range differently in their languages and suggest that expression of social meaning may affect pitch range of the two languages of female and male bilinguals differently

Multidimensional signals and analytic flexibility: Estimating degrees of freedom in human speech analyses

Recent empirical studies have highlighted the large degree of analytic flexibility in data analysis which can lead to substantially different conclusions based on the same data set. Thus, researchers have expressed their concerns that these researcher degrees of freedom might facilitate bias and can lead to claims that do not stand the test of time. Even greater flexibility is to be expected in fields in which the primary data lend themselves to a variety of possible operationalizations. The multidimensional, temporally extended nature of speech constitutes an ideal testing ground for assessing the variability in analytic approaches, which derives not only from aspects of statistical modeling, but also from decisions regarding the quantification of the measured behavior. In the present study, we gave the same speech production data set to 46 teams of researchers and asked them to answer the same research question, resulting insubstantial variability in reported effect sizes and their interpretation. Using Bayesian meta-analytic tools, we further find little to no evidence that the observed variability can be explained by analysts’ prior beliefs, expertise or the perceived quality of their analyses. In light of this idiosyncratic variability, we recommend that researchers more transparently share details of their analysis, strengthen the link between theoretical construct and quantitative system and calibrate their (un)certainty in their conclusions

Perceptual Discrimination of Phonemic Contrasts in Quebec French: Exposure to Quebec French Does Not Improve Perception in Hexagonal French Native Speakers Living in Quebec

In Quebec French, /a ~ ɑ/ and /ε ~ aε/ are phonemic, whereas in Hexagonal French, these vowels are merged to /a/ and /ε/, respectively. We tested the effects of extended exposure to Quebec French (QF) as a second dialect (D2) on Hexagonal French (HF) speakers’ abilities to perceive these contrasts. Three groups of listeners were recruited: (1) non-mobile HF speakers born and living in France (HF group); (2) non-mobile QF speakers born and living in Quebec (QF group); and mobile HF speakers having moved from France to Quebec (HF>QF group). To determine any fine-grained effects of second dialect (D2) exposure on the perception of vowel contrasts, participants completed a same–different discrimination task in which they listened to stimuli paired at different levels of acoustic similarity. As expected, QF listeners showed a significant advantage over the HF group in discriminating between /a ~ ɑ/ and /ε ~ aε/ pairs, thus suggesting an own-dialect advantage in perceptual discrimination. Interestingly, this own-dialect advantage appeared to be greater for the /ε ~ aε/ contrast. The QF listeners also showed an advantage over the HF>QF group, and, surprisingly, this advantage was greater than over the HF group. In other words, the results suggested that the acquisition of a second dialect did not enhance the abilities of listeners to perceive differences between phonemic contrasts in that D2. If anything, the acquisition of the D2 disadvantaged the perceptual abilities of the HF>QF group. This might be because these phonemes have, over time, become less acoustically marked for the HF>QF participants and have, potentially, become integrated into their D1 phonemic categories

Echoes of past contact: Venetian influence on Cretan Greek intonation

Prosodic aspects of cross-linguistic contact are under-researched, especially past contact that has subsequently ceased. In this paper, we investigate declarative and polar question tunes of contemporary Cretan Greek, a regional variety of Greek whose speakers were in contact with Venetian speakers during the four and half centuries of Venetian rule on the island, from 1204 to 1669. The F0 contours of the Cretan tunes and alignment of peaks and troughs of interest with the nuclear vowel are compared to the corresponding tunes in Venetian dialect and Venetian Italian and to those in Athenian (Standard) Greek, which are used as control. The data (1610 declarative utterances and 698 polar questions) were drawn from natural speech corpora based on pragmatic criteria: broad focus for declaratives, broad focus, and information-seeking interpretation for polar questions. The pitch contour shapes of the tunes are modeled using polynomial basis functions, and the F0 alignment points are determined analytically. The results show the robustness of contact effects almost three and a half centuries after regular contact ceased and indicate that the shapes of the F0 contours of Cretan and Venetian declarative and polar question tunes are similar. In addition, Cretan alignment patterns are similar to Venetian and significantly different from Athenian. Insights are gained from research into how long prosodic characteristics may persist in a recipient language—decades or even centuries after the cessation of contact

Lightweight natural lime composites for rehabilitation of historical heritage

Failure and deterioration of structural interventions on masonry buildings demonstrated the need for compatible repairs. Mechanical, chemical, transport properties and density of Portland Cement concrete are poorly compatible with lime mortar masonry structures. Several natural lime composites are developed in this study for compatible Historical Heritage rehabilitation. Two relevant interventions with different strength/density requirements are considered: masonry vault filling and wooden floor non-structural overlay. Density minimization is attained with various lightweight aggregate (LWA) types/contents; different LWAs in one same mortar are also employed. Composites’ density, strength, stiffness, cost, and carbon footprint are compared; the influence of different factors is discussed

Synthesis of a new sulfonated-hexachlorobiphenyl standard for environmental analysis, ecotoxicological, and toxicological studies

Sulfonated-polychlorinated biphenyls (sulfonated-PCBs) are a newly discovered class of PCB metabolites. They were observed for the first time in polar bear serum and lately, in soil, together with hydroxy-sulfonated-PCBs. Their presence is ubiquitous in soils, and their estimated physical chemical properties show high mobility in water, compared to the parent compounds. However, no single pure standards exist so far and therefore their quantification in the environmental matrices is not accurate. Additionally, pure standards are needed to experimentally determine their physical chemical properties, as well as the ecotoxicological and toxicological characteristics. In the present work, the challenging goal of preparing a polychlorinated biphenyl monosulfonic acid was achieved exploring different synthetic approaches, along which the selection of the starting material resulted in a crucial point. Using PCB-153 (2,2'-4,4'-5,5'-hexachloro-1,1'-biphenyl) the synthesis afforded, as the major species, a side compound. On the contrary, the use of PCB-155 (2,2'-4,4'-6,6'-hexachloro-1,1'-biphenyl), a symmetric hexachlorobiphenyl derivative showing chlorine atoms at all the ortho positions, gave the target sulfonated-PCB compound. In this case, sulfonation was successfully carried out through a two-step procedure, involving chlorosulfonylation and the subsequent hydrolysis of the chlorosulfonyl intermediate

Development of a Nanoparticle-Based Approach for the Blood–Brain Barrier Passage in a Murine Model of Amyotrophic Lateral Sclerosis

The development of nanoparticles (NPs) to enable the passage of drugs across blood–brain barrier (BBB) represents one of the main challenges in neuropharmacology. In recent years, NPs that are able to transport drugs and interact with brain endothelial cells have been tested. Here, we investigated whether the functionalization of avidin-nucleic-acid-nanoassembly (ANANAS) with apolipoprotein E (ApoE) would allow BBB passage in the SOD1G93A mouse model of amyotrophic lateral sclerosis. Our results demonstrated that ANANAS was able to transiently cross BBB to reach the central nervous system (CNS), and ApoE did not enhance this property. Next, we investigated if ANANAS could improve CNS drug delivery. To this aim, the steroid dexamethasone was covalently linked to ANANAS through an acid-reversible hydrazone bond. Our data showed that the steroid levels in CNS tissues of SOD1G93A mice treated with nanoformulation were below the detection limit. This result demonstrates that the passage of BBB is not sufficient to guarantee the release of the cargo in CNS and that a different strategy for drug tethering should be devised. The present study furthermore highlights that NPs can be useful in improving the passage through biological barriers but may limit the interaction of the therapeutic compound with the specific target
