Abstract:

Abstract Objective The 22-item PROMIS®-Rx Pain Medication Misuse item bank (Bank-22) imposes a high response burden. This study aimed to characterize the performance of the Bank-22 in a computer adaptive testing (CAT) setting based on varied stopping rules. Methods The 22 items were administered to 288 patients. We performed a CAT simulation using default stopping rules (CATPROMIS). In 5 other simulations, a “best health” response rule was added to decrease response burden. This rule stopped CAT administration when a participant selected “never” to a specified number of initial Bank-22 items (2–6 in this study, designated CATAlt2-Alt6). The Bank-22 and 7-item short form (SF-7) scores were compared to scores based on CATPROMIS, and the 5 CAT variations. Results Bank-22 scores correlated highly with the SF-7 and CATPROMIS, Alt5, Alt6 scores (r=0.87–0.95) and moderately with CATAlt2- Alt4 scores (r=0.63–0.74). In all CAT conditions, the greatest differences with Bank-22 scores were at the lower end of misuse T-scores. The smallest differences with Bank-22 and CATPROMIS scores were observed with CATAlt5 and CATAlt6. Compared to the SF-7, CATAlt5 and CATAlt6 reduced overall response burden by about 42%. Finally, the correlations between PROMIS-Rx Misuse and Anxiety T-scores remained relatively unchanged across the conditions (r=0.31–0.43, Ps < .001). Conclusions Applying a stopping rule based on number of initial “best health” responses reduced response burden for respondents with lower levels of misuse. The tradeoff was less measurement precision for those individuals, which could be an acceptable tradeoff when the chief concern is in discriminating higher levels of misuse.

Abstract:

Coconut shell waste is a waste that has a high carbon content. Carbon in coconut shell waste can be converted into activated carbon having a large surface area. This potential property is suitable to apply the coconut shell as catalyst support. To increase the catalytic activity, metal oxides such as Cr2O3 are impregnated. The purpose of this study is to synthesize Cr2O3/carbon catalyst and test its catalytic activity on catalytic cracking of Jatropha oil. The first stage was the synthesis of activated carbon and the determination of its proximate and ultimate. The second step was impregnation to produce Cr2O3/carbon catalyst. Furthermore, X-Ray Diffraction to determine crystallinity, Surface Area Analyzer to identify its surface area and Fourier Transform Infrared to analyze functional groups. Then the catalytic activity was tested on the catalytic cracking of Jatropha oil. In addition, the chemical compound composition and biofuel selectivity of the catalytic cracking product was determined using Gas Chromatography-Mass Spectrometer. Proximate analysis results showed that activated carbon contains 9%, 1%, 23%, and 67% of water, ash, evaporated substances, and bound carbon, respectively. The results of the ultimate analysis resulted in carbon (C), hydrogen (H), and nitrogen (N) contents of 65.422%, 3.384%, and 0.465%, correspondingly. The catalyst crystallinity test showed the presence of Cr2O3 peaks at 2θ: 24.43°; 33.47° and 36.25° according to JCPDS No. 84-1616. In the absorption area of 400-1000 cm-1 and the range of 2000 cm-1 showed the presence of Cr-O stretching due to Cr2O3 adsorbed into the activated carbon structure. The surface area of activated carbon and Cr2O3/carbon catalysts with a concentration of 1.3, and 5% was 8.930 m2/g; 47.205 m2/g; 50.562 m2/g; and 38.931 m2/g, respectively. The catalytic activity test presented that the best performance was showed by Cr2O3/carbon catalyst with a concentration of 5% indicated by conversion of Jatropha oil into biofuel of 67.777% with gasoline selectivity, kerosene, and diesel of 36.97%, 14.87%, and 15.94%, correspondingly.

Abstract:

Here, we reported the utilization of coconut shell charcoal used for solid acid catalysts and its performance in the esterification reaction of acetic acid and methanol. The graphitization of coconut shell charcoal was carried out by the calcination and KOH activation at the temperature of 400 °C for an hour and continued at the temperature of 800 °C for an hour under nitrogen flow resulted in graphitic carbon. The effect of the addition of KOH activation was observed by varied the weight ratio of coconut shell charcoal as raw material (RM) and KOH. The selected weight ratio of RM:KOH was 1:1, 1:2, and 1:4. The resulted graphitic carbon was sulfonated by heating with the sulfuric acid to obtain a solid acid catalyst. The sulfonic time was evaluated for 5 and 10 hours. The generated particles were characterized to examine the morphology, the crystallinity, the specific surface area, the chemical bonding, and the ionic capacity using Scanning Electron Microscopy (SEM), X-Ray diffraction (XRD), nitrogen gas absorption-desorption, Fourier Transform Infrared Spectroscopy (FTIR), and titration method, respectively. The best condition for graphitization of raw material is the use of RM:KOH = 1:4, resulting in the highest surface area reaching 1259.67 m2/g and the most dominant of the sulfonic group of −SO3 bond. Furthermore, increasing the sulfonating time from 5 to 10 hours led to the increase of the yield of esterification reaction from 85% to 96.57% for graphite synthesized using RM:KOH = 1:4.

Abstract:

Palm oil mill effluent (POME) is the largest liquid waste from crude palm oil production. This liquid waste still contains a lot of chemical components, solid deposits, and oil which is dangerous if released directly into the environment. The residual oil and grease components contained in POME can be further extracted and converted into fuel fractions. This study investigates the conversion of residual oil from POME into fuel fractions through hydrocracking. A ZrO2/Sarulla natural zeolite (SNZ) catalyst was used, characterized by a particle size of 1-1.5 µm, a surface area of 73.3 m2/g, a pore volume of 0.161 cc/g, and a pore diameter of 3.35 nm. The effect of catalyst mass was studied, with the total conversion increasing to a certain extent with increasing catalyst mass, however, an increase in coke formation decreased the product yield. The highest gasoline fraction selectivity was obtained with a catalyst mass of 0.09 wt% (~42%), while the kerosene fraction was most obtained with a catalyst mass of 0.15 wt% (~40%). The liquid product with a catalyst mass of 0.15 wt% had the highest HHV of 44.2 MJ/kg, a 12% increase from the HHV of POME oil residue (39.4 MJ/kg). The results demonstrate the potential of using residual oil from POME as a source for fuel production and the use of natural zeolite-based catalysts as hydrocracking catalysts.

Abstract:

A mechanical design “compiler” has been developed which, given an appropriate schematic, specifications, and utility function for a mechanical design, returns catalog numbers for an optimal implementation. The compiler has been successfully tested on a variety of mechanical and hydraulic power transmission designs, and a few temperature sensing designs. Times required have been at worst proportional to the logarithm of the number of possible combinations of catalog numbers.

Abstract:

Utilizing lignocellulosic biomass into valuable products, such as chemicals and fuels, has attracted global interest. One of lignocellulosic biomass, palm oil empty fruit bunch (EFB), has major content of cellulose (30-40%), which is highly potential to be a raw material for fermentable sugar production. In this research, a series of sulfonated carbon catalysts with various concentrations of sulfuric acid (H2SO4, 10-30 v/v%) solutions have been successfully prepared and applied for a single stage of heterogeneous acid-catalyzed hydrolysis over microcrystalline cellulose and EFB under moderate temperature condition and ambient pressure. The catalysts’ physical and chemical properties were characterized by using a Thermogravimetric Analyzer (TGA), X-ray diffractometer, surface area analyzer, and Fourier-transform infrared spectrophotometer. The characterization results showed that sulfonated carbon had relatively similar physical properties with the parent of active carbon. The hydrolysis activity of sulfonated carbon catalysts gave various Total Reducing Sugar (TRS). The effects of sulfate loading amount in catalyst samples and various ionic liquids were investigated. The hydrolysis of pure microcrystalline cellulose powder (Avicel) using 30%-sulfonated carbon (30-SC) catalyst in 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) ionic liquid at 150°C yielded the highest TRS of 16.11%. Subsequently, the catalyst of 30-SC was also tested for hydrolysis of EFB and produced the highest TRS of 40.76% in [BMIM]Cl ionic liquid at 150°C for 4 h. The obtained results highlight the potential of sulfonated carbon catalysts for hydrolysis of EFB into fermentable sugar as an intermediate product for ethanol production.

Abstract:

Cu-Mn-Si catalysts with copper-manganese oxides as the main constituents and silica dioxide as the supports were prepared by co-precipitation method. The performance of the catalysts for the dehydrogenation reaction of the 2-butanol to methyl ethyl ketone was tested. The effects of Cu and Mn ratios on the catalytic performance were investigated. The catalysts were characterized by XRD, SEM, H2-TPR, TG, BET and XPS, to reveal the catalytic mechanism. The results showed that after adding the manganese, the copper-manganese complexes were formed in the catalysts, which effectively improved the activity of the catalysts. XRD results showed that a new phase of Cu-Mn complex was formed in the fresh catalysts, and reduced copper species appeared in the spent catalysts; TPR results showed that the reduction temperature of the catalysts could be reduced by adding appropriate amount of manganese; XPS results showed that the proportion of Cu++Cu0 can be increased in the fresh catalyst and that of Cu2+ in the spent catalyst can be decreased after the addition of manganese. When the mole ratio of Cu, Mn and Si in the catalysts was 0.8:0.2:1, the conversion of 2-butanol could reach 94.9%, and the selectivity of methyl ethyl ketone was 98%.

Abstract:

Objective: To evaluate the effects of Catalpa bignonioides fruit extract on the promotion of muscle growth and muscular capacity in vitro and in vivo. Methods: Cell viability was measured using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Cell proliferation was assessed using a 5-bromo-2’-deoxyuridine (BrdU) assay kit. Western blot analysis was performed to determine the protein expressions of related factors. The effects of Catalpa bignonioides extract were investigated in mice using the treadmill exhaustion test and whole-limb grip strength assay. Chemical composition analysis was performed using high-performance liquid chromatography (HPLC). Results: Catalpa bignonioides extract increased the proliferation of C2C12 mouse myoblasts by activating the Akt/mTOR signaling pathway. It also induced metabolic changes, increasing the number of mitochondria and glucose metabolism by phosphorylating adenosine monophosphate-activated protein kinase. In an in vivo study, the extract-treated mice showed improved motor abilities, such as muscular endurance and grip strength. Additionally, HPLC analysis showed that vanillic acid may be the main component of the Catalpa bignonioides extract that enhanced muscle strength. Conclusions: Catalpa bignonioides improves exercise performance through regulation of growth and metabolism in skeletal muscles, suggesting its potential as an effective natural agent for improving muscular strength.

Abstract:

Sebastián-Gallés et al. [The influence of initial exposure on lexical representation: Comparing early and simultaneous bilinguals. Journal of Memory and Language, 52, 240–255, 2005] contrasted highly proficient early Spanish-Catalan and Catalan-Spanish bilinguals, using Catalan materials in a lexical decision task (LDT). They constructed two types of experimental pseudowords, substituting Catalan phoneme /e/ for Catalan /ɛ/, or vice versa. Catalan-dominant bilinguals showed a performance asymmetry across experimental conditions, making more mistakes for /ɛ/→/e/ changes, than for /e/→/ɛ/ ones. This was considered evidence of a developed acceptance of mispronounced Catalan /ɛ/-words, caused by exposure to a bilingual environment where mispronunciations by Spanish-dominant bilinguals using their /e/-category abound. Although this indicated modified or added lexical representations, an open issue is whether such lexical information also modifies phoneme categories. We address this using a biophysically realistic neurodynamic model, describing neural activity at the synaptic and spiking levels. We construct a network of pools of neurons, representing phonemic and lexical processing. Carefully analyzing the dependency of network dynamics on connection strengths, by first exploring parameter space under steady-state assumptions (mean-field scans), then running spiking simulations, we investigate the neural substrate role in a representative LDT. We also simulate a phoneme discrimination task to address whether lexical changes affect the phonemic level. We find that the same network configuration which displays asymmetry in the LDT shows equal performance discriminating the two modeled phonemes. Thus, we predicted that the Catalan-dominant bilinguals do not alter their phoneme categories, although showing signs of having stored a new word variation in the lexicon. To explore this prediction, a syllable discrimination task involving the /e/-/ɛ/ contrast was set up, using Catalan-dominants displaying performance asymmetry in a repetition of the original LDT. Discrimination task results support the prediction, showing that these subjects discriminate both categories equally well. We conclude that subjects often exposed to dialectal word variations can store these in their lexicons, without altering their phoneme representations.

Abstract:

Purpose The aim of this study was to compare Basque and Catalan bilinguals' performance on the letter verbal fluency test and determine whether significant differences are present depending on the letters used and the language of administration. Method The sample consisted of 87 Spanish monolinguals, 139 Basque bilinguals, and 130 Catalan bilinguals from Spain. Participants completed the letter verbal fluency test using the letters F, A, S, M, R, P, and E. Results Bilinguals scored higher on the letter verbal fluency test when they were tested in Spanish than in Basque or Catalan. No performance differences were found according to native language or dialects within Basque participants. Catalans with Spanish as their native language scored lower on the letter F compared to those who grew up speaking Catalan and Spanish. The suggested letters to use with Basque speakers are A, E, and B; the suggested letters to use with Catalan speakers are P, F, and M; and the suggested letters to use with Spanish speakers are M, R, and P. Conclusion Selecting appropriate stimuli depending on the language of testing is the first crucial step to assess verbal fluency and thus possible frontal lobe functioning impairment.

Abstract:

This study explores how proficiency in a second language determines the way that lexical and semantic representations are functionally connected in bilingual memory by testing three groups of participants (beginning and intermediate Spanish-Catalan learners and highly proficient bilinguals). The experiment reported examines how form and semantic manipulations affect the performance of these groups in a translation recognition task using three types of word relations (very close and close semantically related word pairs and form-related pairs). The results reveal that form manipulation affects the performance of the three participant groups, whereas the influence of semantic relations depends on the participants’ level of proficiency. Results are discussed within the framework of the Revised Hierarchical Model (Kroll & Stewart, 1994).

Abstract:

Resum: Mitjançant aquest article proposem una revisió de la petjada del teatre en la cultura catalana del segle xvii. Més concretament revisarem la bibliografia al voltant dels espais de representació i obres representades als teatres de Barcelona i València, destacant la difusió de les comèdies de Lope de Vega en aquests dos espais. Revisem quin és l’impacte del Fénix sobre els teatres, tant pel que fa a les estructures físiques de representació com a la difusió de les comèdies. Repassem algunes dades rellevants al voltant de la presència de companyies teatrals a València i Barcelona, i mirem de discernir quines obres s’hi representarien, encaixant-les en el panorama peninsular per poder valorar el rol d’aquestes dues ciutats catalanoparlants en el món de les representacions teatrals. Finalment, plantegem algunes hipòtesis sobre l’existència d’un teatre profà en català i els possibles entorns i formats per a la circulació del teatre.Paraules clau: teatre, Lope de Vega, representació, comèdies, circulació.Abstract: This article proposes a review of the importance of theatre in Catalan culture in the 17th century. More specifically, we will review the bibliography on the performance spaces and plays performed in the theatres of Barcelona and Valencia, highlighting the dissemination of Lope de Vega’s comedies in these two spaces. We review the impact of the Fénix on the theatres, both in terms of the physical structures of performance and the diffusion of the plays. We review some relevant data about the presence of theatre companies in Valencia and Barcelona, and we try to discern which plays would be performed there, focusing them in the peninsular panorama in order to evaluate the role of these two Catalan-Partilian cities in the world of theatrical performances. Finally, we put forward some hypotheses about the existence of a profane theatre in Catalan and the possible environments and formats for the circulation of the theatre.Keywords: theatre, Lope de Vega, performance, comedies, circulation.

Abstract:

Library catalogs have represented stagnant technology for close to twenty years. Moving toward a next-generation catalog, North Carolina State University (NCSU) Libraries purchased Endeca’s Information Access Platform to give its users relevance-ranked keyword search results and to leverage the rich metadata trapped in the MARC record to enhance collection browsing. This paper discusses the new functionality that has been enabled, the implementation process and system architecture, assessment of the new catalog’s performance, and future directions.

Abstract:

The seismic event in May 2006 underscored the critical necessity of continuous earthquake monitoring. Observational enhancement through adding more stations is very crucial to obtain a more refined data quality. From January 2009 to September 2019, BMKG PGR (Pusat Gempa Regional/Regional Earthquake Centre) VII documented approximately 1847 seismic events with magnitudes from 0.9 to 4.9. With the integration of additional seismic station into the array by December 2022, there was a notable increase of 1418 recorded events in the same magnitude interval. The earthquake observation average is increasing as well, from 15.4 events in a month to 20.5 events in a month. This study leverages this data to assess the impact of augmenting seismic stations proximal to the Opak Fault on seismicity parameters within that region. Employing ZMAP 6.0, a comparative analysis of seismicity parameters was conducted between the earthquake catalog from January 2009 to September 2019 and the expanded catalog from January 2009 to December 2022. Declustering process result 1790 and 3141 main earthquake events in each catalog. This research indicate that the inclusion of more stations significantly influences the Mc value and earthquake density, however, it does not have a significant effect on the b and a-value.

Abstract:

Different methods to remove the alcohol of adduct MgCl2nEtOH were studied to obtain Ziegler-Natta catalysts for evaluation in ethylene and propylene polymerization. Thus, the adduct MgCl2nEtOH was submitted to thermal dealcoholation, as well as chemical dealcoholation with different substances: titanium tetrachloride, triethylaluminum, and dichloro-dimethylsilane. Thermogravimetric analyses (TGA) were performed to obtain information on the thermal characteristics of adducts and prepared supported catalysts. Ethylene and propylene homopolymerization were carried out with the prepared catalysts and the polymers were characterized.

Abstract:

AbstractThe production of a well-constructed narrative is the culmination of several years of language acquisition and is an important milestone in children's development. There is no current description of narrative development for Catalan speaking children. This study collected elicited narratives in Catalan from 118 children aged 4;0–10;11. Narratives were scored for macrostructure and microstructure. Narrative scores improved with age with maximum performance for macrostructure by 9 years. Children's ability to use micro-structural components of Catalan is variable with some developments continuing beyond 9 years. The results are discussed in relation to theoretical arguments about universal and specific features of narrative development. We conclude by highlighting the usefulness of the new test for future language assessment of children acquiring Catalan.

Abstract:

Forests, the production by the iconoclastic Spanish-Catalan director Calixto Bieito staged at the ‘Old’ Birmingham Repertory Theatre in September 2012, functions here as the starting point for an exploration of the way a radical revisioning of Shakespeare in performance stimulated through an engagement with European modernism began in this now venerable theatre over 100 years ago. What was dubbed Bieito’s ‘epic arboreal mash-up’ was I suggest haunted by the material traces of groundbreaking past performances mounted by the Rep’s founder Barry Jackson, which included the first Shakespeare in modern-dress productions of the 1920s and the highly influential 1951–53 staging of the Henry VI trilogy.

Abstract:

Abstract The Third Data Release (DR3) of the Gaia mission almost doubled the number of RR Lyrae (RRL) stars release in its Specific Object Studies (SOS) catalog, in comparison with DR2. Here I provide empirically inferred 2D and 3D completeness maps for the Gaia DR3 SOS RRL catalog along with maps for the combined Gaia SOS+PS1+ASAS-SN-II catalog. The latter currently has the best performance with an improvement of 9% relative to Gaia DR3 alone and close to 20% relative to Gaia DR2 for the VC+SOS RRL, while significantly smoothing out the effect of the Gaia scanning law.

Abstract:

Most of the models proposed in the literature for abstractive summarization are generally suitable for the English language but not for other languages. Multilingual models were introduced to address that language constraint, but despite their applicability being broader than that of the monolingual models, their performance is typically lower, especially for minority languages like Catalan. In this paper, we present a monolingual model for abstractive summarization of textual content in the Catalan language. The model is a Transformer encoder-decoder which is pretrained and fine-tuned specifically for the Catalan language using a corpus of newspaper articles. In the pretraining phase, we introduced several self-supervised tasks to specialize the model on the summarization task and to increase the abstractivity of the generated summaries. To study the performance of our proposal in languages with higher resources than Catalan, we replicate the model and the experimentation for the Spanish language. The usual evaluation metrics, not only the most used ROUGE measure but also other more semantic ones such as BertScore, do not allow to correctly evaluate the abstractivity of the generated summaries. In this work, we also present a new metric, called content reordering, to evaluate one of the most common characteristics of abstractive summaries, the rearrangement of the original content. We carried out an exhaustive experimentation to compare the performance of the monolingual models proposed in this work with two of the most widely used multilingual models in text summarization, mBART and mT5. The experimentation results support the quality of our monolingual models, especially considering that the multilingual models were pretrained with many more resources than those used in our models. Likewise, it is shown that the pretraining tasks helped to increase the degree of abstractivity of the generated summaries. To our knowledge, this is the first work that explores a monolingual approach for abstractive summarization both in Catalan and Spanish.

Abstract:

The present study aims to discuss some politeness strategies in 13–16th century Catalan, based on a corpus pragmatic analysis of requests from the Computerized Corpus of Old Catalan (Corpus Informatitzat del Català Antic [CICA]), found by searching for occurrences of the speech act verbs pregar ‘ask, pray’ and suplicar ‘supplicate, beg, beseech’. Results of the present study provide evidence that politeness in 13–16th century Catalan was realized by different linguistic means than in contemporary Catalan. It focuses on some conventionally indirect strategies that consisted in using the verb voler ‘want’ to transfer the imperative force from the performance of the requested act to the hearer’s willingness. At the intersection of speech act research, politeness studies, historical pragmatics and corpus pragmatics, this study also discusses some methodological challenges of these areas.

Abstract:

The Stolpersteine (‘stumbling stones’) memorial project commemorates victims of Nazi violence and the Holocaust through an individual marker installed outside the last willing residence before deportation and execution. The Stolpersteine project has spread throughout Europe, providing an urban topography of sites where traumatic events occurred. Because Stolpersteine are placed in public streets, they create performance possibilities, inviting passing pedestrians to engage in past history and trauma. As the project grows throughout Europe, however, the universality of the stones abuts with the specificity of local history and memory. This article considers the Stolpersteine installed in the Catalan city of Manresa. These stones, representing twenty-eight Spanish Republicans who were interned at the Mauthausen-Gusen concentration camp, are framed by a Catalan-language audio guide that directly points to the collaboration of the Francisco Franco dictatorship with Nazi Germany. In so doing, the stones in Spain also stand for violence meted out during the Spanish Civil War and the Franco dictatorship.

Abstract:

Spain is a multilingual country where three additional official languages coexist (Catalan, Basque and Galician) with the state language (Spanish). The high costs of translation impose that policy makers are permanent negotiating which percentage of information should be provided in each language. Against this background, the language in the field of education is a controversial topic. In this research we focus on how students´ mother tongue, as an ethnic attribute, determines their school performance. Our results confirm that there is a premium for those students whose mother tongue is Catalan, and that living in those communities where Basque and Galician are spoken, affects also positively the academic performance.

Abstract:

The catalytic performance of titania-supported carbon mesoporous-derived from fish bones (TiO2/CFB) has been investigated in styrene oxidation with aqueous H2O2. The preparation steps of (TiO2/CFB) catalyst involved the carbonization of fish bones powder at 500 °C for 2 h. followed by impregnation of titania using titanium(IV) isopropoxide (500 µmol) precursor, and calcined at 350 °C for 3 h. The physical properties of the adsorbents were characterized using Fourier transform infrared, X-ray diffraction (XRD), Scanning electron microscopy with energy dispersive X-ray (SEM-EDX), and nitrogen adsorption-desorption studies. The catalytic test was carried out using styrene oxidation with H2O2 as an oxidant at room temperature for 24 h. Its catalytic activity was compared with Fe2O3/CFB, CuO/CFB, TiO2, and CFB catalysts. It is demonstrated that the catalytic activity of TiO2/CFB catalyst has the highest compared to Fe2O3/CFB, CuO/CFB, TiO2, and CFB catalysts in the oxidation of styrene with styrene conversion ~23% and benzaldehyde selectivity ~90%. Kinetics of TiO2/CFB catalyzed oxidation of styrene has been investigated and mechanism for oxidation of styrene has been proposed. Copyright © 2021 by Authors, Published by BCREC Group.

Abstract:

When participants are asked to translate an ambiguous word, they are slower and less accurate than in the case of single-translation words (e.g., Láxen & Lavour, 2010; Tokowicz & Kroll, 2007). We report an experiment to further examine this multiple-translation effect by investigating the influence of variables shown to be relevant in bilingual processing. The experiment included cognates and non-cognates with one translation or with multiple translations. The latter were presented with their dominant or subordinate translations. Highly-proficient balanced bilinguals responded to a translation recognition task in the two language directions (Catalan–Spanish and Spanish–Catalan). The results showed a significant multiple-translation effect in both cognates and non-cognates. Moreover, this effect was obtained regardless of language dominance and translation direction. Participants were faster and more accurate when performing translation recognition for the dominant than for the subordinate translations. The findings are interpreted adopting the Distributed Representation Model (de Groot, 1992b).

Abstract:

The paper introduces the concept of generalized Catalan numbers as a useful tool for solving many theoretical and applied combinatorial-probabilistic problems. Combined with analytical transformation software algorithms, the generalized Catalan numbers simplify the solution of many problems in computer science and applied mathematics. In particular, they turn out to be an effective tool for solving problems related to the registration of random-dot images, in signal transformations of various degrees of smoothness, and when developing speed-optimal algorithms for searching for pulsed-point objects with a random generation time of super short pulses. The proposal of the authors to formulate the problems of enumerative combinatorics in a word-symbolic form naturally leads to multidimensional extensions of the classical Catalan numbers and has several advantages. The combined use of multidimensional Catalan numbers and high-performance computer algebra systems enables solving a number of complex applied problems related to the reliability of the registration of random-dot images.

Abstract:

This study investigates utterance-final pitch accents in declaratives in two contact languages (Catalan and Spanish) as produced by two groups of Catalan–Spanish bilinguals (Catalan-dominant and Spanish-dominant). It contributes to a growing body of research showing that bilinguals transfer the intonational patterns of their native language to their non-native language, and it provides a sociolinguistic profile of an intonational variable in a language contact situation. We also examine the interaction of native and non-native patterns within the performance of the bilinguals. Evidence is presented for the existence of a process of phonetic category assimilation of non-native pitch contrasts to native pitch contours, as well as for phonetic new-category formation in second language learning.
