THE EMERGENT PROSODIC SYSTEM(S) OF BILBAO-AREA STANDARD BASQUE

The aim of this study is to contribute to the larger body of research concerned with the prosodic systems of the Basque dialects currently spoken in Southern Basque country. More specifically, the author focuses on Standard Basque from the Bilbao area and its potential prosodic system(s). Standard Basque was phonologically codified by the Basque Academy, but there was no prosodic system provided by the Basque Academy. Although initial investigations have been undertaken by Hualde, more current research has shown that the standard spoken outside of the classroom is different from that which is taught (Lantto, 2019; Rodríguez-Ordóñez, 2016). Given that prosody is rarely taught within the classroom, it would not be surprising for differences to be found. The most obvious difference between Standard Basque and some of the traditional dialects is that Standard has no word-level contrastive stress; functions such as singular/plural distinctions and case are marked by postpositions. What has been determined is that the prosodic system of Standard Basque, or Batua, patterns closely to that of Gipuzkoan Basque. However, as noted by Hualde & Elordieta (2014), there is little knowledge regarding the variation of the functioning of Standard Basque’s acoustic correlates. As stated by Elordieta & Hualde (2001), it is only after a comparison of the intonational characteristics of the currently spoken dialects has been conducted that a typological categorization of Basque prosodic systems can be made. As Standard Basque was not codified with a prosodic system, it ultimately comes down to what individual speakers and speaker groups have done to account for this in their standard dialect productions. It cannot be presumed that the prosody of SB (Standard Basque) found in one region will exactly line up with prosody found in other regions; these too would need to be documented and analyzed as prosodic sub-systems. One major gap in current research is the analysis of intonation at the phrasal level; Gaminde et al. (2011) look at acoustic correlates and their respective force, but only at the word level. While Hualde looks at intonation, the study uses Gipuzkoan Basque used as a substratum, which constricts the findings to that particular dialectal region. For this reason, the dialect of Batua spoken in the Bilbao area proves to be worth investigating. The local dialect of the area was long ago lost, such that Batua could be said to be the Bilbao dialect. The revitalization movement of the 1960s brought about a significant number of new speakers, who learned the standard variety in school. To add to this, Bilbao’s presence as a major commercial hub has made it so that there is a vast number of regional vernaculars circulating throughout the area, all in contact with one another. For this study, data was taken from 6 Basque-Spanish bilinguals whose primary dialect of Basque is the standard, that participated in two experimental tasks: eliciting words in isolation in one task and eliciting neutral declaratives and yes-no questions in the other. These tasks were a means of gathering raw data on the intonation of both word and phrasal level productions. Results supports the previous findings of Gaminde et al. (2015) as well as those of Aurrekoetxea et al. (2015), in terms of how stress is realized in Standard Basque when taking into account factors such as syllable weight and syllable count. What’s more, findings also support the proposition of Hualde & Beristain (to appear) that inter-speaker variation will be heavily affected by the contact speakers have with other dialects of Basque

Periodic orbits high above the ecliptic plane in the solar sail 3-body problem

Due to the non-central nature of the force on a solar sail, there exist equilibrium points of the equations of motion out of the ecliptic plane in the Sun-Earth-Sail circular restricted 3-body problem, in contrast with the classical Lagrange points. Analogous to the 'halo' orbits, we construct large amplitude periodic orbits about these equilibria. By timing the period of the orbit we may negate the seasonal effects of the variation in the Earth's axis of rotation, and thus the sail's position when viewed from the pole subtends a much smaller angle (around 8 deg rather than 46 deg). These orbits are of practical interest with regards to communication with, and constant imaging of, the poles

Package Delivery Using Drones with Restricted Movement Areas

For the problem of delivering a package from a source node to a destination node in a graph using a set of drones, we study the setting where the movements of each drone are restricted to a certain subgraph of the given graph. We consider the objectives of minimizing the delivery time (problem DDT) and of minimizing the total energy consumption (problem DDC). For general graphs, we show a strong inapproximability result and a matching approximation algorithm for DDT as well as NP-hardness and a 2-approximation algorithm for DDC. For the special case of a path, we show that DDT is NP-hard if the drones have different speeds. For trees, we give optimal algorithms under the assumption that all drones have the same speed or the same energy consumption rate. The results for trees extend to arbitrary graphs if the subgraph of each drone is isometric

Drosophila nuclear proteins bind to regions of alternating C and T residues in gene promoters

Proteins from Drosophila nuclei that bind to regions of alternating C and T residues present in the promoters of the heat shock genes hsp70 and hsp26 and the histone genes his3 and his4 have been purified. These proteins bind to isolated linear DNA, and genomic footprinting analyses indicate that they are bound to DNA in nuclei. In supercoiled plasmids at low pH, some of these DNA sequences adopt triple-helical structures which, if they form in vivo, could significantly affect chromatin structure. The nuclear proteins described here, and not necessarily the deformed conformation of the DNA, may be responsible for maintaining a potentially inducible promoter structure before transcriptional activation

Time without time: a stochastic clock model

We study a classical reparametrization-invariant system, in which ``time'' is not a priori defined. It consists of a nonrelativistic particle moving in five dimensions, two of which are compactified to form a torus. There, assuming a suitable potential, the internal motion is ergodic or more strongly irregular. We consider quasi-local observables which measure the system's ``change'' in a coarse-grained way. Based on this, we construct a statistical timelike parameter, particularly with the help of maximum entropy method and Fisher-Rao information metric. The emergent reparametrization-invariant ``time'' does not run smoothly but is simply related to the proper time on the average. For sufficiently low energy, the external motion is then described by a unitary quantum mechanical evolution in accordance with the Schr\"odinger equation.Comment: 18 pages; LaTeX. 4 (.ps) plus 2 (.gif) figure file

Quenching Effects in the Hadron Spectrum

Lattice QCD has generated a wealth of data in hadronic physics over the last two decades. Until relatively recently, most of this information has been within the "quenched approximation" where virtual quark--anti-quark pairs are neglected. This review presents a descriptive discussion of the effects of removing this approximation in the calculation of hadronic masses.Comment: To appear in "Lattice Hadron Physics", ed. A.C.

Estimating the cost-effectiveness of brief interventions for heavy drinking in primary health care across Europe

Background Screening and Brief Interventions for alcohol are an effective public health measure to tackle alcohol-related harm, however relatively few countries across the European Union (EU) have implemented them widely. This may be due to a lack of understanding of the specific financial implications of such policies within each country. Methods A novel ‘meta-modelling’ approach was developed based on previous SBI cost-effectiveness models for four EU countries. Data was collected on the key factors which drive cost-effectiveness for all 28 EU countries (mean per capita alcohol consumption, proportion of the population to be screened over a 10-year SBI programme; per capita alcohol-attributable mortality; per capita alcoholattributable morbidity; mean cost of an alcohol-related hospitalisation and mean SBI-delivery staff cost). Regression analysis was used to fit two meta-models estimating net programme costs and quality-adjusted life-years (QALYs) gained, to calculate cost-effectiveness estimates specific to each EU country. Results Costs are dependent upon the proportion of the population covered by the screening programme, the country-specific per capita mortality and morbidity rate and the country-specific costs of GP care and hospitalisation. QALYs depend on the proportion of the population screened and per capita alcohol consumption. Despite large inter-country variability in factor values, SBI programmes are likely to be cost-effective in 24 out of 28 EU countries and cost-saving in about 50% of countries. Conclusion Implementing national programmes of SBI in primary health care would be a cost-effective means of reducing alcohol-attributable morbidity and deaths in almost all countries of the EU
