BARRIERS TO ADVANCED HERITAGE LANGUAGE DEVELOPMENT
Authors: Ashtari Nooshan , Krashen Stephen
Published: October 2023

Speakers of heritage languages do not universally achieve advanced levels in the language. We present evidence that three barriers are responsible: (1) lack of access to comprehensible, interesting reading material in the heritage language. (2) The use of traditional language teaching methods in heritage language classes, and (3) the reactions of elders who scold young heritage language speakers for their “errors.”
ЯТРОГЕННЫЙ ВРЕД: ПРОТИВОРЕЧИЯ ПОНИМАНИЯ
Authors: Тихомиров Алексей
Published: October 2023

Не любые телесные повреждения при медицинском воздействии являются вредом здоровью, но лишь профессионально недопустимые. Не являются вредом неизбежные и допустимые при медицинском воздействии телесные повреждения. В той мере, в какой вред обусловлен действиями причинителя, обусловленные характером патологии и реактивностью организма пациента телесные повреждения вредом также не являются. Вред здоровью потребителя, обусловленный деятельностью с источником повышенной опасности и оказанием сопутствующих услуг, происходит от причин иного происхождения, чем ятрогения. Дифференциация вреда здоровью по источникам предопределяет адресата ответственности и не заставляет врача отвечать за несовершенство самой медицины.
Musotto en la praxis
Authors: Mellid Leandro
Published: October 2023

Una de las problemáticas que resuena en los estudios sobre música popular latinoamericana es la falta de categorías de análisis pensadas desde y para determinadas producciones. La relación de los componentes musicales con las formas de vida, creencias y conocimientos de las comunidades donde se gestan o se han gestado determinadas producciones artísticas no es tomada en cuenta a la hora de hacer un análisis de músicas afroderivadas. Una propuesta desde una perspectiva decolonial y afrocentrada es la que desarrolló Ramiro Musotto, antes de su desaparición física, en su Teoría de claves y la serie escondida. Analizaremos una de sus músicas partiendo de una conceptualización sobre las claves rítmicas e intentaremos ampliar la mirada poniendo en juego no solo los aspectos musicales sino también epistemológicos de las comunidades afrobrasileñas en las que Musotto basó su trabajo.

Identifying Potential Household Waste as Secondary Raw Materials in the Construction Industry: A Case Study of Sri Lanka
Authors: Weerakoon Thilina Ganganath , Wimalasena Sulaksha , Zvirgzdins Janis
Published: October 2023

The construction sector contributes significantly to waste generation and resource depletion. Identifying potential household waste for reuse and recycling as secondary raw materials has emerged as a key technique for addressing these environmental concerns. This study uses the Colombo municipality in Sri Lanka to identify and evaluate household waste products having the potential to be reused as secondary raw materials in the construction sector. The study employs a mixed method for data collection and analysis. First, a questionnaire survey of industry experts was conducted to identify and assess the requirements for household waste that may be utilized in the construction sector, followed by a complete literature analysis to determine the reuse applications of potential household waste. The findings of this study will be useful in identifying and evaluating household waste items that may be recycled as secondary raw materials in the construction sector. It would also help to establish sustainable waste management techniques and circular economy practices in Sri Lanka. The study’s findings can help policymakers, waste management authorities, and stakeholders in the construction industry to implement effective waste management practices and promote the use of recycled materials in construction projects, reducing environmental impact and conserving natural resources.
The role of impartial administration in financial sector performance: A comparative study of Latin America and Sub-Saharan African countries
Authors: Dirir Sadik Aden
Published: October 2023

Emerging nations are often distressed if their current administration and governance do not align with social and national needs. Among these worries, there is the fear of public funds misconduct and corruption in the nation’s major institutions. Indeed, inadequate administration results in embezzlement of funds, tax evasion, and low bureaucratic quality in all sectors. This study was undertaken to address the role of impartial administration specifically in the financial sector. The research considered a sample size composed of 12 countries from Latin America and Sub-Saharan Africa in the period of 2000 to 2021. The net interest margin was considered a proxy for financial performance measurement. Additionally, an ordinary least squares and quantile regression was performed to record the effect of the variables on financial sector performance. Within this context, the findings exhibited different outcomes for these regions. For instance, in the Latin America region, the results revealed that public sector theft, bureaucratic quality, corruption level, local government index, and inflation have a negative impact on the performance of the financial sector while impartial public administration demonstrated a positive impact on financial performance. On the other hand, the Sub-Saharan African region demonstrated that bureaucratic quality, local government index, and inflation have a significant and positive impact on financial performance, whereas executive embezzlement and theft, corruption level, and government final expenditures were shown to negatively influence financial performance. Finally, the study’s findings provides insights into the policies and strategies to implement in order to support the financial framework.
Games in a foreign exchange market and solutions
Authors: Habibi Reza
Published: October 2023

Exchange rate and its related risk management are too important for main participants in foreign exchange markets. There are many approaches developed in the literature for studying risk management say arbitrage detection, say finding replication portfolio. However, in the current paper, arbitrage opportunities are studied using the game theory perspective. This paper proposes different types of games played in a specified foreign exchange market in the presence of three exchange rates. Proposed games are exchange rate games in two cases of no arbitrage and existence of arbitrage, optimal stopping game, the arbitrage game, threshold strategies used in global game and Non-cooperative exchange rate game. Most of cases, the bang-bang rule of optimal control is used for finding the Nash equilibriums (NE). However, simulated and stochastic approximation (SA) solutions are also given. Most highlights of the current paper are: (I) considering two types of arbitrage opportunities, simultaneously, (II) translating arbitrage detection as game theory concepts, (III) solving the problem using techniques of optimal control theory. Finally concluding remarks are proposed.
A 10-Year Analysis of Housing Prices and The Influence of Economic Factors in Turkey
Authors: Muddasir Muhammad , Dondaş Umut
Published: October 2023

In Turkey, the housing market is affected by various factors, and housing prices are shaped according to current conditions. In this study, the relationship between the housing price index (HPI) and economic variables (inflation and exchange rate) in Turkey was investigated. We used a 10-year time period for this study, from January-2010 to December-2019, with monthly data frequency. For our research, we employ the Wavelet Coherence Transformation (WCT) method. The results show that there is a positive relationship between inflation and housing prices in the short and long run. In addition, a continuous rise in inflation led to an increase in housing prices all over the period from 2010 to 2019. The findings of this study can aid in achieving the goal of the research by offering evidence-based perceptions of how housing prices and different economic variables are related. Housing costs in Turkey increased as a result of the substantial likelihood that the Turkish lira would weaken. The expansion of global inflation is a further anticipated factor contributing to the rise in housing costs in Turkey. This study can also be used by investors to help them decide whether to engage in the Turkish real estate industry.
Reassessing the Long-Run Abnormal Performance of Jordanian IPOs: An Event Study Approach
Authors: Al Shawawreh Fawaz Khalid
Published: October 2023

This paper examines and reviews the fundamental challenges that academicians face when using the event study methodology to assess the long-term consequences of financial events on the economy and to describe market reactions. Numerous studies have demonstrated that businesses can experience abnormal returns from 1 to 5 years after major financial events. Also, this paper investigates the long-run price performance of initial public offerings (IPOs) in Amman Stock Exchange (ASE). The sample period expands from 2018 to 2022. Various findings are obtained by employing several analytical methods. First, long-run price performance of IPOs is negative, and a strong evidence shows that the long-run performance is sensitive to the benchmark employed. To assess the long-term performance of IPOs, I used both cumulative abnormal returns (CAR) and buy-and-hold abnormal returns (BHAR) as aggregated models. I explained the methodology which is adopted in this study in detail for the event–time approach. However, I used the crucial values for the skewness-adjusted t-statistic to infer statistical tests. Even though BHAR provided weaker results, all methods indicated negative long-run abnormal returns for IPOs. Yet this performance varied when comparing the performance utilizing ASEI, Fama–French three-factor (FF3F), and matching firm (MF) as benchmarks.

The article assesses the changes in the state of Ukraine’s natural environment, namely due to the fire on its territories as a result of military operations. Remote sensing can be considered as a decision support tool for landscape management, remote sensing plays a vital operational tool in the affected areas to assess the consequences, as well as to make appropriate decisions to protect the environment and support environmental recovery programs in these areas.

This paper presented applying of remote sensing methods to assess large fires caused by military events in Ukraine war using the VIIRS spectroradiometer (375 m) on board the NASA/NOAA Suomi NPP satellite and NOAA-20 satellites, as well as NASA’s Fire Information for Resource Management System (FIRMS) resource. The paper presents examples of the use of remote sensing to detect changes in territories affected by military operations, and provided estimates of the total number of fires in 2022. Authors proposed a methodology for obtaining daily data on the localization of fires in the territories of active hostilities, in particular in 15 regions of Ukraine that are closest to the front line. Results of this paper indicated the VIIRS spectroradiometer and the FIRM’s resource as an effective tool for monitoring fires and assessing changes in the environment caused by them as a result of military operations in Ukraine.

The possibility of using satellite imagery for operational fire monitoring has been proven, which, in combination with traditional ground-based data, can play a crucial role in protecting civilians and providing evidence of environmental violations.

Published: October 2023

Public transport priority is an essential transport engineering technique for the transition to sustainable urban mobility. This article presents a case study that simulates the effects of introducing a queue jump lane followed by a bus lane beyond an intersection compared to a dedicated lane only in the section beyond the intersection (without introducing a queue jump lane). The monitored parameters were speed and reliability of public transport. The simulation was performed using the PTV Vissim program. The case study was evaluated in terms of public transport operation, as well as selected effects on other road traffic with the aim to determine the optimal traffic engineering design and improve public transport operation in practice. This case study provides valuable insights into the effects of these priority measures. The results can contribute to the improvement of public transport operations.

Authors: Kovárník Richard , Staňková Michaela
Published: October 2023

This article deals with the assessment of the technical efficiency of the automotive industry in European countries. Unlike other studies, the paper will focus on international comparisons of efficiency while taking account company size. The analysis is thus based on the accounting data of individual companies. The content of the analysis covers the period between 2015 and 2019. In total, companies from 20 European countries shall be analysed. The results show that the level of efficiency in this sector is related to the size of the enterprise. In general, small enterprises turn out to be the least efficient. However, there is also a difference in the level of efficiency in the different size groups of enterprises depending on their geographical location, where in general, irrespective of the size category, Ukrainian enterprises appear to perform worst.
Borderlands in times of crisis: The possibility of de-marginalisation of the Polish border zone with Russia after the outbreak of war in Ukraine
Authors: Studzińska Dominika
Published: October 2023

The Polish-Russian border, closed since the outbreak of the Covid-19 pandemic, transformed into an iron curtain without any chance for its disappearance in a long-term perspective. The ongoing conflict between Russia and the EU started an experiment in the Polish zone bordering with Russia with respect to the planning of economic growth in the new reality – in a fully isolated area – where the border is a limitation and not an opportunity. According to the author’s research, the crisis caused by the permanent closing of the Polish-Russian border and suspension of contacts with the Kaliningrad Oblast, which initially was a hard blow for the border communes, with a particularly difficult economic situation, may – in the long-term perspective – turn out to be an important driving force for changes. The primary purpose of this paper is to identify the main actions taken by the Polish local authorities at the border with Russia, the aim of which is revitalisation of the local economy after the Polish-Russian border was closed. The article is based on a number of in-depth expert interviews carried out in the Polish border area.
Numerical studies of plasma edge in W7-X with 3D FINDIF code
Authors: Jabłczyńska Małgorzata , Pełka Grzegorz , Jakubowski Marcin , Ślęczka Marcin
Published: October 2023

Modelling of the plasma transport for inherently three-dimensional (3D) problems as in stellarators requires dedicated complex codes. FINDIF is a 3D multifluid plasma edge transport code that has been previously successfully used for the analysis of energy transport in the TEXTOR-DED tokamak [1], where 3D perturbations led to an ergodic structure of field lines in the plasma edge. The ongoing efforts to apply it meaningfully to Wendelstein 7-X (W7-X) plasma problems resulted in advancements in the main model and accompanying tools for mesh generation and post-processing. In order to verify the applicability of the code and to compare with the reported simulation (EMC3-EIRENE) and experimental (OP1.1) results, a series of simulations for varying plasma density, temperature and anomalous transport coefficients as well as for fixed input power were performed. The connection length pattern of FINDIF traced magnetic field lines on the limiter was reproduced and its impact on heat loads was confirmed. An increase in the peak heat load on the limiter with a rise in plasma density, temperature and anomalous plasma transport coefficients was observed. The decay lengths of density, electron temperature and heat flux did not change with density, and were decreasing with temperature and increasing with anomalous plasma transport coefficient, which was compared to the simple scrape-off layer (SOL) model.

Authors: Mihai Maleanu , Carmen Racanel
Published: October 2023

The urban and economic developments of recent years have generated changes in the development of road traffic, determined by the continuous growth of the vehicle fleet, the increase in the mobility index of the existing vehicle fleet and the increase in the number of vehicles transiting the main cities of the country, this having as consequences the decrease in the traffic capacity of the streets. Through the application of innovative technologies, which allow the anticipation and control of road traffic, traffic jams are avoided, this leads to an increase in the quality of life. In this article, a case study was analyzed, in which an artificial neural network was implemented within a traffic model, with the help of which predictions were made on traffic light times. The results obtained are satisfactory, and are highlighted by the performance parameters exported from the traffic models.
A critical discourse analysis of the representation of Ukrainian refugees across the British mainstream news media
Authors: Munandar Imam , Akmal Saiful
Published: October 2023

This research investigates the dominant rhetorical/ discursive strategies in the British mainstream news media regarding their reports on Ukrainian refugees in the United Kingdom (UK). While news media have negatively constructed the non-European refugees, as previous studies have revealed, this research is unique because it specifically focuses on European refugees as its research sample. The ultimate objective was to demonstrate how the news media in the UK portrayed the incoming Ukrainian refugees on British soil. The data were 40 Ukrainian-refugee-related news reports published in four mainstream news media in the UK from March until July 2022. The data was then analysed by using Wodak’s Discourse-Historical Approach (DHA), consisting of six analytical categories: Referential, Predication, Argumentation (Topoi), Perspectivisation, Mitigation, and Intensification (Reisigl Wodak, 2008). The research found that regardless of their ideologies, all four news media consistently employed the discursive strategies of humanization and individualization and pervasively established a positive argumentative strategy on Ukrainian refugees. These dominant strategies depict a positive representation of Ukrainian refugees. Moreover, despite the overall negative picture of third-world refugees in British news media, the finding of this research is distinctive from the previous ones, showing that the British news media actively constructed the Ukrainian refugees positively and sympathetically. It is argued that the news media’s ideological stance of Eurocentrism and biased racial values played a decisive role in framing the pictures of European/Ukrainian and non-European refugees in their reports.

Authors: Qaddumi Husam Ahmad , Smith Matt , Alawneh Yousef , Shawamreh Nader , Bakeer Aida , Itemizeh Mahmoud
Published: October 2023

Despite foreign language classroom anxiety having been studied since the 1980s, there has been little research into this phenomenon in the context of online and blended learning environments. There is a clear need for this study as higher education becomes ever more adaptable, post-pandemic. The portfolio of methods for supporting teaching and learning is widening, with most institutions now offering online and hybrid modules and courses. The purpose of this study was to investigate the levels of anxiety among Palestinian undergraduates learning the English language through online courses. This study also investigated the effects of gender variables (310 males and 1210 females) on foreign language classroom anxiety levels. We surveyed a random sample of 1520 undergraduate students from different universities in Palestine. We used the well-established Foreign Language Classroom Anxiety Scale FLCAS (Horwitz et al., 1986; Horwitz, 2016), which is the most commonly-used measure of anxiety related to language learning. The findings of the study revealed that undergraduate learners experience anxiety when speaking with native speakers. Results indicate no significant differences in the students’ gender and foreign language classroom anxiety at universities. However, female learners were more anxious in language classrooms where the level of classroom anxiety was high. Finally, we offer tentative solutions for how tutors can support students experiencing foreign language anxiety.

Китайские мигранты и региональная администрация на российском Дальнем Востоке во второй половине XIX – начале XX в. в свете исследований Джеймса Скотта
Authors: Позняк Татьяна Зиновьевна
Published: October 2023

В статье анализируется дискурс и практики взаимодействия китайских мигрантов и представителей российского государства в приграничном регионе в рамках концепций Дж.Скотта. Автор останавливается на нескольких сюжетах из истории этого взаимодействия на российском Дальнем Востоке во второй половине XIX - начале XX в. Автор приходит к выводу, что возможны различные толкования фактического материала: в одних случаях мы можем интерпретировать неподвластность китайцев российским властям как подвластность маньчжурским, в других – как разнообразные формы сопротивления любому государству. В текстах российской власти сквозит озабоченность неподконтрольностью и нелояльностью китайцев, но уже наличие этого дискурса и усилий региональной администрации по установлению контроля над азиатскими мигрантами свидетельствует о начавшемся процессе установления подвластности "Зомии" государству.

Корейские земледельцы в России: 100 лет повседневного сопротивления
Authors: Рыжова Наталья Петровна
Published: October 2023

Статья посвящена практикам рутинного (ненаправленного на смену власти) сопротивления российских корейцев в имперской России, раннем и позднем СССР. Автор следует научной программе, заложенной Дж. Скоттом, но при этом отказывается от его идеи о последовательности государства. Работа демонстрирует, как неформальные экономические практики корё сарам (кобонди, базарная торговля, производство "корейских салатов") были связаны с другими формами ненаправленного сопротивления. Парадоксальной "другой формой", в советское время стал ударный труд, который удивительным образом сочетался с неизменным использованием традиционных корейских практик обработки земли (бюрократы для его обозначения часто использовали термин "азиатский способ (техники)"). Статья разделена на две части, в первой части обсуждается как российские имперские чиновники, военные, агрономы относились к азиатским аграрным техникам, а также предпринята попытка ответить на вопрос, был ли имперский российский Дальний Восток скоттовской "Зомией" для корейцев. Работа опирается на архивные источники, публикации о корё сарам, собственные полевые материалы автора.

Китайские овощеводы в советских селах: работники или арендаторы?
Authors: Иванов Сергей Александрович
Published: October 2023

Статья исследует феномен китайского овощеводства в СССР в 1988–1991 гг. На материалах архивов и устной истории Пограничного района Приморского она показывает, что с организационно-правовой точки зрения аренда стала основой аграрного производства бригад из КНР на полях совхозов, хотя руководство последних препятствовало развитию такой формы хозяйствования в отношениях с советскими работниками. Автор выделяет управленческие практики и дискурсивные процедуры, которые позволяли сгладить противоре- чия, порождаемые работой китайских бригад, и сформировать в районном дискурсе устойчивый образ китайцев не как автономных арендаторов, а как наемных работников.

"Они сажали алюминиевые огурцы на брезентовых полях": мигранты из Средней Азии и КНР в сельских районах Урала
Authors: Александрович Авдашкин Андрей , Ильфатовна Фаткулина Ильмира
Published: October 2023

В статье на основе полевых материалов авторов, собранных в 2019–2023 гг. на территории Челябинской и Свердловской областей, а также публикаций медиа-ресурсов рассматривается дискурс об отторжении "другими" пространства в сельских районах Урала. Территориальные рамки обусловлены тем, что именно в этих двух регионах размещалось основное количество тепличных комплексов, маркированных как китайские. Ключевой исследовательский вопрос состоит в следующем: как происходит формирование представлений о сельских локациях, отторгнутых у "местных" мигрантами из КНР и Средней Азии. Опасения, связанные с образованием мигрантских анклавов в крупных российских городах, не нашли убедительного подтверждения. Однако потенциальная возможность образования подобных объектов в сельской местности вызывает значитель- ное беспокойство общественности. Несмотря на то, что в теплицах уже практически не встречаются китайцы, представления об их "китайскости" наполняются все новым содержанием. Китайская теплица представляется сосредоточением мигрантскости, чуждых принимающей стороне архаичных практик, направленных на "захват" пространства "другими", нанесение ущерба "нам". В этом смысле теплицы как хозяйственный объект и совокупность социальных отношений маркируются прежде всего этническими категориями – в данном случае "китайскостью" – даже в тех случаях, когда заметную часть рабочих составляют вовсе не китайцы, а мигранты из Средней Азии или местные жители. Ключевые слова: миграция, мигранты, китайские теплицы, ксенофобия, Урал

Authors: Almeida Thomas , Bucater Raisa , Pires Thalia , Anbar Isabela , Botelho Fernanda
Published: October 2023

Objective: To report on a case of a child with influenza subtype A H1N1 who exhibited a spontaneous pneumothorax as an initial manifestation of the illness. Case Description: A 8-year-old male patient experienced a dry cough in the 24 hours prior developed dyspnea, productive cough, tachypnea, tachycardia, and subcutaneous emphysema. Upon admission to the emergency ward, the patient was tachycardic with bilaterally palpable subcutaneous emphysema in the thoracic wall, was reliant on an oxygen mask, and experienced drops in arterial oxygen saturation. Chest and lung examinations revealed coarse crackles, expiratory wheezing, and suprasternal retraction. Patient received a corticosteroid, a bronchodilator, and an antibiotic. Imaging exams revealed bilateral pneumothoraces and bilateral subcutaneous emphysema. Patient was hospitalized in the Pediatric Intensive Care Unit (ICU). Bilateral chest drainage was installed; intubation and mechanical ventilation were initiated. On the sixth day after admission, the test for A/H1N1 came back positive. Patient was released from the Pediatric ICU on the ninth day and was released from the hospital the following day without symptoms. Comments: A pneumothorax as an early manifestation of A/H1N1 is a rare occurrence in children. This case reflects the need for broader differential diagnostic options in children with spontaneous pneumothoraces.

Authors: Oliveira Susana , Freitas Francisca , Fonseca Antonio , Ramires Ricardo , Tavares Cláudia
Published: October 2023

Introduction: Urolithiasis is uncommon in children. Suspicion should be raised in the presence of exaggerated clinical manifestations. Case Report: An eleven-year old uncircumcised adolescent male was referred to a pediatric nephrology consultation complaining of recurrent episodes of dysuria with emission of black calculus. He had no lumbar or abdominal pain, nor gross hematuria. On physical examination, Giordano sign was negative bilaterally. His laboratory evaluation, urinalysis and ultrasound were unremarkable. A 24-hour urine collection had no noteworthy alterations. Stone analysis was unconclusive. No metabolic or infectious cause for a calculus was identified. The calculus was sent to an outside laboratory and rubber elastomer was detected. After determining the stones were self-induced, the adolescent was referred to Pedopsychiatry appointment. No further signs or symptoms of nephrolithiasis were reported. Discussion: Although Factitious Disorders caused by proxy have been increasingly recognized, there is a significant less awareness that children and adolescents can intentionally falsify symptoms.

Authors: Montaño José I. , Dossman Ximena , Herrera Julián A. , Bromet Arnoldo , Moreno Carlos H.
Published: October 2023

Objective: The aim of the study was to describe the prevalence of Helicobacter pylori and psychosocial stress in patients with chronic gastritis. Methods: A pilot case-control study was performed in patients with chronic gastritis. The study group included patients infected with H. pylori and the control group included patients without infection. The patients were recruited at the Valle University Hospital (VUH) and the Valle del Lili Foundation (VLF) in Cali, Colombia during 2003. The H. pylori infection was determined by gastric endoscopy and the psychosocial stress by the Hospital Anxiety Depression Scale (HADS). Results: 164 patients were included, 74 (45.1%) in VUH and 90 (54.9%) in VLF. The socio-demographic characteristics were comparable in both institutions and both groups. H. pylori infection was observed in 113 (68.9%) patients and psychosocial stress in 115 (70.1%). Anxiety levels were higher than depression levels; (anxiety median=9, range 1-20; depression median=6, range 0-17) especially in VUH (p=0.03) associated to low socioeconomic status (p< 0.01). The psychosocial stress was not associated with H. pylori infection (p=0.69). Conclusion: Patients with chronic gastritis had a high prevalence of H. pylori infection and psychosocial stress without association between the two variables.

Published: October 2023

Introduction: There are few studies that describe the effects of cannabinoids in the gastric system, although in only one, there was the description of a gastric pH alteration. Objective: To determine the anti-secretory effect of the species Cannabis sativa. Methodology: In this study forty five Sprague Dawley rats were used, they were submitted to a 24 hours fasting period, after which the pylorus was ligated for 2-4 hours, according to the experimental group. Thereafter, the rats were anesthetized, their stomachs extirpated and the gastric content analyzed for volume and pH. Results: The Cannabis extract raised the gastric pH when compared to the control group (p < 0.05), with no significant differences found between the reference drug (ranitidine) and the Cannabis extract (p >0.05). There were no differences in the measured volumes. Conclusions: These results suggest that the Cannabis sativa extract diminishes the gastric acid output.

In contrast to most commercial air traffic today, vehicles serving the urban air mobility (UAM) market are anticipated to operate within communities and be close to the public at large. The approved model for assessing environmental impact of air traffic actions in the United States, the Federal Aviation Administration Aviation Environmental Design Tool (AEDT), does not directly support analysis of such operations due to a combined lack of UAM aircraft flight performance model data and aircraft noise data. This paper addresses the latter by offering two prediction-based approaches for generation of noise–power–distance data for use within AEDT. One utilizes the AEDT fixed-wing aircraft modeling approach, and the other utilizes the AEDT rotary-wing aircraft modeling approach.

In this work, the parameters of the porous structure and adsorption properties of carbon enterosorbents Zoocarb and SUMS-1 were studied. Organic dyes methylene blue and methanyl yellow were used as substances simulating toxic compounds of low molecular weight. It has been established that the carbon enterosorbent Zoocarb has a high adsorption activity with respect to these substances compared to SUMS-1. The nature of the obtained isotherms of methanyl yellow adsorption differs, which indicates the difference between the mechanisms of its adsorption by sorbents. This is due to the different composition of functional groups on the surface of the studied sorbents and their textural characteristics. The most promising sample for use in enterosorption for the removal of low molecular weight toxic substances is the carbon sorbent Zoocarb.
Ambiguidade pronominal em orações adverbiais do português europeu: crianças vs. adultos
Authors: Lobo Maria , Carolina Silva
Published: October 2023

This paper investigates how European Portuguese children interpret null and overt subject pronouns of adverbial clauses when there are two potential antecedents in the main clause, in order to find out how early the preferred readings are acquired in European Portuguese for each type of pronoun. Our results show that the control group of adults behaves as expected, choosing more often subject antecedents for null subjects and non-subject antecedents for subject pronouns, but children are predominantly at chance. The preferred interpretation for null subjects is acquired earlier than the one for overt pronouns and anaphoric contexts are acquired earlier than cataphoric ones. We attribute this developmental pattern to the fact that null pronouns are morphosyntactically more deficient and less dependent on semantic, discourse and prosodic factors, and to processing constraints related to the linear position of the antecedent.
Ensaio sobre a revisão da oralidade
Authors: Paula Taveira  , Santos Diana
Published: October 2023

This paper discusses the revision of the transcription of oral interviews done by the Portuguese Museu da Pessoa to preserve the life histories of common people, often with little or no formal education, which had been transcribed by students without linguistic training. This task increased our awareness of how orality works and of how many choices a transcriber is required to make, being a sort of translator. In addition, it uncovered a set of «errors» or deviations in many elderly speakers from the North of Portugal which are often considered typically Brazilian, leading us to reconsider variety divergence.

Dispersions of charged maghemite nanoparticles (NPs) in EAN (ethylammonium nitrate), a reference Ionic Liquid (IL), are here studied using a number of static and dynamical experimental techniques; Small Angle Scattering (SAS) of X-rays and of neutrons, dynamical light scattering and forced Rayleigh scattering. Particular insight is provided regarding the importance of tuning the ionic species present at the NP/IL interface; In this work we compare the effect of Li+, Na+ or Rb+ ions. The nature of these species has here a clear influence on the short-range spatial organization of the ions at the interface and thus on the colloidal stability of the dispersions, governing both the NP/NP and NP/IL interactions, which are here both evaluated. The overall NP/NP interaction is either attractive or repulsive. It is characterized by determining, thanks to the SAS techniques, the second virial coefficient A2, which is found independent of temperature. The NP/IL interaction is featured by the dynamical effective charge ξoeff of the NPs and by their entropy of transfer SˆNP (or equivalently their heat of transport QˆNP) determined here thanks to thermoelectric and thermodiffusive measurements. For repulsive systems, an activated process rules here the temperature dependence of these two latter quantities.
Ultrafast Excited-State Dynamics of Luteins in the major light-harvesting complex LHCII

Carotenoid pigments are known to present a functional versatility when bound to light-harvesting complexes. This versatility originates from a strong correlation between a complex electronic structure and a flexible geometry which is easily tunable by the surrounding protein environment. Here, we investigated how the different L1 and L2 sites of the major trimeric light-harvesting complex (LHCII) of green plants tune the electronic structure of the two embedded luteins, and how this reflects on their ultrafast dynamics upon excitation. By combining molecular dynamics and quantum mechanics/molecular mechanics calculations, we found that the two luteins feature a different conformation around the second dihedral angle in the lumenal side. The s-cis preference of the lutein in site L2 allows for a more planar geometry of the π-conjugated backbone, which results in an increased degree of delocalization and a reduced excitation energy, explaining the experimentally observed red shift. Despite these remarkable differences, according to surface hopping simulations the two luteins present analogous ultrafast dynamics upon excitation: the bright S2 state quickly decays (in ∼50 fs) to the dark intermediate Sx, eventually ending up in the S1 state. Furthermore, by employing two different theoretical approaches (i.e., Förster theory and an excitonic version of surface hopping), we investigated the experimentally debated energy transfer between the two luteins. With both approaches, no evident energy transfer was observed in the ultrafast timescale
