Published: January 2024

Abstract. Lightning is one of the primary natural sources of nitric oxide (NO), and the influence of lightning-induced NO (LNO) emission on air quality has been investigated in the past few decades. In the current study an LNO emissions model, which derives LNO emission estimates from satellite-observed lightning optical energy, is introduced. The estimated LNO emission is employed in an air quality modeling system to investigate the potential influence of LNO on tropospheric ozone. Results show that lightning produced 0.174 Tg N of nitrogen oxides (NOx = NO + NO2) over the contiguous US (CONUS) domain between June and September 2019, which accounts for 11.4 % of the total NOx emission. In August 2019, LNO emission increased ozone concentration within the troposphere by an average of 1 %–2 % (or 0.3–1.5 ppbv), depending on the altitude; the enhancement is maximum at ∼ 4 km above ground level and minimum near the surface. The southeastern US has the most significant ground-level ozone increase, with up to 1 ppbv (or 2 % of the mean observed value) difference for the maximum daily 8 h average (MDA8) ozone. These numbers are near the lower bound of the uncertainty range given in previous studies. The decreasing trend in anthropogenic NOx emissions over the past 2 decades increases the relative contribution of LNO emissions to total NOx emissions, suggesting that the LNO production rate used in this study may need to be increased. Corrections for the sensor flash detection efficiency may also be helpful. Moreover, the episodic impact of LNO on tropospheric ozone can be considerable. Performing backward trajectory analyses revealed two main reasons for significant ozone increases: long-distance chemical transport and lightning activity in the upwind direction shortly before the event.

Abstract. Extensive continuous particle number size distribution measurements took place during two summers (2020 and 2021) at 11 sites in Greece for the investigation of the frequency and the spatial extent of new particle formation (NPF). The study area is characterized by high solar intensity and fast photochemistry and has moderate to low fine particulate matter levels during the summer. The average PM2.5 levels were relatively uniform across the examined sites. The NPF frequency during summer varied from close to zero in the southwestern parts of Greece to more than 60 % in the northern, central, and eastern regions. The mean particle growth rate for each station varied between 3.4 and 8 nm h−1, with an average rate of 5.7 nm h−1. At most of the sites there was no statistical difference in the condensation sink between NPF event and non-event days, while lower relative humidity was observed during the events. The high-NPF-frequency sites in the north and northeast were in close proximity to both coal-fired power plants (high emissions of SO2) and agricultural areas with some of the highest ammonia emissions in the country. The southern and western parts of Greece, where NPF was infrequent, were characterized by low ammonia emissions, while moderate levels of sulfuric acid were estimated (107 molec. cm−3) in the west. Although the emissions of biogenic volatile organic compounds were higher in western and southern sectors, they did not appear to lead to enhanced frequency of NPF. The infrequent events at these sites occurred when the air masses had spent a few hours over areas with agricultural activities and thus elevated ammonia emissions. Air masses arriving at the sites directly from the sea were not connected with atmospheric NPF. These results support the hypothesis that ammonia and/or amines limit new particle formation in the study area.

Published: January 2024

Abstract. We have studied the ionospheric upwelling with magnitude above 1013 m−2 s−1 using the data during the IPY-ESR 2007 campaign, which coincides with solar minimum. The noise level in low, medium and high-flux upflows is investigated. We found that the noise level in high-flux upflow is about 93 % while the low and medium categories are 62 % and 80 %, respectively. This shows that robust and stringent filtering techniques must be ensured when analysing incoherent data in order not to bias the result. Analysis reveals that the frequency of the low-flux upflow events is about 8 and 73 times the medium and high-flux upflow events, respectively. Seasonal observation shows that the noise level in the upflow classes is predominantly during winter. The noise is minimal in summer, with a notable result indicating occurrence of actual data above noise in the low-flux class. Moreover, the percentage occurrence of the noise level in the data increases with increasing flux strength, irrespective of the season. Further analysis reveals that the noise level in the local time variation peaked around 17 – 18 LT and minimum around local noon.
Nordic Seas Deep-Water susceptible to enhanced freshwater export to the subpolar North Atlantic during peak MIS 11

Published: January 2024

Abstract. Recent investigations into Marine Isotope Stage (MIS) 11 (424–403 ka), an unusually long and warm interglacial of the Quaternary Period, have found that the Atlantic Meridional Overturning Circulation remained strong while background melting of the Greenland Ice-Sheet (GIS) was high, and resulted in a fresh and cold surface ocean in the Nordic Seas. These investigations support the hypothesis that deep-water formation may not be as susceptible to future GIS melting as previously thought. Here we test this hypothesis and present a palaeoceanographic investigation of a freshwater-related abrupt climate event recorded in the eastern North Atlantic during peak interglacial conditions (~412 ka), when the GIS was as small or smaller than today. Using sediment core DSDP-610B recovered from the western Rockall Trough we reconstruct the evolution of Nordic Seas Deep-Water (NSDW) using benthic carbon isotope, Neodymium isotopes, and grain-size analysis paired with end-member modelling. Further, a combination of planktonic foraminiferal assemblage census and Ice-Rafted Debris counts allow us to reconstruct surface water properties including temperature and the movement of oceanic fronts throughout this event. Our results demonstrate that a reduction of NSDW only occurs once GIS melt and polar freshwater reaches subpolar latitudes. We hypothesise that the reorganisation of fresh and cold surface waters from the Nordic Seas into the subpolar North Atlantic was responsible for an AMOC-related cold event centred at 412 ka. Placing our results in the palaeogeographical context of the North Atlantic Region we tentatively propose that the ocean-atmosphere climate dynamics linking the Nordic Seas with the subpolar North Atlantic played and will play a crucial role for the stability of NSDW formation in the future, considering the enhanced melting and overall hydrological cycle at high Northern latitudes predicted for future climate scenarios.

Abstract. Wetlands are the largest natural source of atmospheric methane and highly vulnerable to climate change. In our study we aim to better understand the environmental controls on the strength and seasonal variation of methane flux components from hollows, typically the high-emitting wettest microtopographic features in a boreal bog. We measured methane fluxes from intact vegetation as well as on vegetation removal treatments and analyzed pore water methane concentrations and stable carbon isotopes of dissolved and emitted methane. Using these data, we quantified the rates of total methane emission, methane oxidation and plant-mediated methane transport for the summer and shoulder seasons of 2021 and 2022. Total methane emissions from areas with intact vegetation range from 13 to 2171 mgCH4 m–2 d–1 during shoulder seasons and summer months and are mainly controlled by the leaf area of aerenchymatous plants. Methane oxidation in the Sphagnum moss layer decreases total methane emissions by 82 ± 20 % while transport of methane through aerenchymatous plants increases methane emissions by 80 ± 22 %. Both methane oxidation and plant-mediated methane transport rates follow a seasonal cycle with lower but still significant rates during the shoulder seasons compared to the summer months. As a net effect, the presence of Sphagnum mosses and vascular plants reduces methane emissions from the study site. This balance, however, appears to be highly sensitive to climate change, i.e. increasing soil temperatures and changing leaf area and composition of the wetland vegetation. The provided insights can help to improve the representation of environmental controls on the methane cycle and its seasonal dynamics in process-based models to more accurately predict future methane emissions from boreal peatlands.

Abstract. This paper describes the rationale and the protocol of the first component of the third simulation round of the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP3a, http://www.isimip.org, last access: 2 November 2023) and the associated set of climate-related and direct human forcing data (CRF and DHF, respectively). The observation-based climate-related forcings for the first time include high-resolution observational climate forcings derived by orographic downscaling, monthly to hourly coastal water levels, and wind fields associated with historical tropical cyclones. The DHFs include land use patterns, population densities, information about water and agricultural management, and fishing intensities. The ISIMIP3a impact model simulations driven by these observation-based climate-related and direct human forcings are designed to test to what degree the impact models can explain observed changes in natural and human systems. In a second set of ISIMIP3a experiments the participating impact models are forced by the same DHFs but a counterfactual set of atmospheric forcings and coastal water levels where observed trends have been removed. These experiments are designed to allow for the attribution of observed changes in natural, human, and managed systems to climate change, rising CH4 and CO2 concentrations, and sea level rise according to the definition of the Working Group II contribution to the IPCC AR6.
Using synthetic float capabilities in E3SMv2 to assess spatio-temporal variability in ocean physics and biogeochemistry

Abstract. Since their advent over two decades ago, autonomous Argo floats have revolutionized the field of oceanography, and more recently, the addition of biogeochemical and biological sensors to these floats has greatly improved our understanding of carbon, nutrient, and oxygen cycling in the ocean. While Argo floats offer unprecedented horizontal, vertical, and temporal coverage of the global ocean, uncertainties remain about whether Argo sampling frequency and density capture the true spatio-temporal variability of physical, biogeochemical, and biological properties. As the true distributions of, e.g., temperature or oxygen are unknown, these uncertainties remain difficult to address with Argo floats alone. Numerical models with synthetic observing systems offer one potential avenue to address these uncertainties. Here, we implement synthetic biogeochemical Argo floats into the Energy Exascale Earth System Model version 2 (E3SMv2). Since the synthetic floats sample the model fields at model run time, the end-user defines the sampling protocol ahead of any model simulation, including the number and distribution of synthetic floats to be deployed, their sampling frequency, and the prognostic or diagnostic model fields to be sampled. Using a six-year proof-of-concept simulation, we illustrate the utility of the synthetic floats in different case studies. In particular, we quantify the impact of i) sampling density on the float-derived detection of deep-ocean change in temperature or oxygen and on float-derived estimates of phytoplankton phenology, ii) sampling frequency and sea-ice cover on float trajectory lengths and hence float-derived estimates of current velocities, and iii) short-term variability in ecosystem stressors on estimates of seasonal variability.
Using specularity content to evaluate eight geothermal heat flow maps of Totten Glacier

Published: January 2024

Abstract. Geothermal heat flow (GHF) is the dominant factor affecting the basal thermal regime of ice sheet dynamics. But it is poorly defined for the Antarctic ice sheet. We compare the basal thermal state of the Totten Glacier catchment as simulated by eight different GHF datasets. We use a basal energy and water flow model coupled with a 3D full-Stokes ice dynamics model to estimate the basal temperature, basal friction heat and basal melting rate. In addition to the location of subglacial lakes, we use specularity content of the airborne radar returns as a two-sided constraint to discriminate between local wet or dry basal conditions and compare the returns with the basal state simulations with different GHFs. Two medium magnitude GHF distribution maps derived from seismic modelling rank well at simulating both cold- and warm-bed regions, the GHFs from Shen et al. (2020) and Shapiro and Ritzwoller (2004). The best-fit simulated result shows that most of the inland bed area is frozen. Only the central inland subglacial canyon, co-located with high specularity content, reaches the pressure melting point consistently in all the eight GHFs. Modelled basal melting rates in the slow-flowing region are generally 0–5 mm yr−1 but with local maxima of 10 mm yr−1 at the central inland subglacial canyon. The fast-flowing grounded glaciers close to the Totten ice shelf are lubricating their bases with meltwater at rates of 10–400 mm yr−1.

la Zone de santé d’Oicha est depuis plus de deux décennies sous l’empire de groupes armés semant mort et désolation y compris la destruction d’une dizaine des centres de santé et ayant occasionnes la délocalisation de certains d’entre eux.  A la suite de l’errance, une partie majeure de la population vit dans le camp des déplacées internes, dans les écoles dans une grande promiscuité et en dessous du minimum de dignité humaine.  Ainsi l’objectif générale de cette étude consiste à identifier les facteurs associes à l’émergence de la rougeole dans la Zone de santé. Pour y parvenir nous avons utilisé une méthode descriptive dans une approche transversale. Les données ont été collectes à l’aide d’un guide d’interview, ces données ont été synthétisées par les statistiques descriptives. Le test de chi-carré et le p-value à 95% d’intervalle de confiance nous ont permis de tester le niveau d’association entre la variable dépendante et les variables indépendantes. Le paquet de statistiques en sciences sociales(SPSS) nous a servi à générer le résultat.Le résultat a révélé que 65% des personnes ayant développés la rougeole n’était pas vacciné. L’état de malnutrition a été associé à l’émergence de l’épidémie, (p-value 0.015). Cependant, une non association  significative entre  la résidence, distance entre le site vaccination, la perception de la nécessite du vaccin, confiance au vaccin, la perception de la sécurité dans le milieu, la compatibilité du vaccine et les croyances, disponibilité du vaccine dans les sites de vaccination et la vaccination anti rougeoleuse (p≥0,05 non significatif au seuil conventionnel de 5%. Les autorités de la zone de santé en collaboration avec leur partenaire, le PEV et le gouvernement Congolais doivent multiplier les efforts pour stabiliser la zone sur le plan sécuritaire et accroitre la desserte de la Zone en vaccin de ma manière permanente pour éviter l’émergence d’épidémie similaire dans l’avenir.

Published: January 2024

Este artigo traz um olhar sobre o conceito de habitar proposto pelo filósofo Martin Heidegger exposto no ensaio ‘Construir Habitar Pensar’ e as intersecções deste conceito e o fazer arquitetônico. O estudo configura-se pela via do interesse intelectual, pois visa aprofundar-se no entendimento do conceito de habitar e sua relação com a arquitetura. A arquitetura dialoga com o conceito de habitar em diversos momentos, seja na relação que estabelece com o lugar e os elementos do sítio, seja nas decisões e intenções projetuais, tais aspectos tangem desde a criação arquitetônica até a conformação final e uso da arquitetura. O conceito de habitar proposto pelo filósofo mostra que a arquitetura concretiza-se em si mesma como próprio habitar uma vez que, ela resulta de um conjunto de escolhas intencionais e que configura um modo de ser no mundo. Almeja-se que as questões aqui apresentadas seja um convite para repensarmos o modo como habitamos o/no mundo tanto enquanto pessoas quanto como profissionais arquitetas.
Os Regimes de Visibilidade no Jardim do Passeio Público no Rio de Janeiro
Authors: Martins Christiane Chagas , Moura Rachel de Almeida
Published: January 2024

O objetivo deste artigo é demonstrar os regimes de visibilidades construídos na forma configurada do jardim barroco do Passeio Público do Rio de Janeiro, do século XVIII. Assim, apresentamos como os elementos espaciais e a maneira como eles estão posicionados na paisagem servem para manipular e legitimar regimes de verdades ao submeter valores sociais de um grupo sobre outros. A base metodológica desta pesquisa advém do diálogo entre as concepções da Geografia cultural e da Arqueologia da Paisagem. Nesse sentido, destacamos dois regimes de visibilidades a partir da análise das plantas arquiteturais e diversos tipos de imagens como fotografias e pinturas do jardim em foco: o primeiro refere-se aos valores maçônicos através da representação de alguns de seus símbolos e o segundo, aos valores monárquicos e do mundo aristócrático por meio de uma geometria manipuladora e da relação entre luz e sombra. A disposição dos signos no jardim dirige movimentos, estimula afetos e determina pontos de vista.
A paisagem festiva e a articulação entre o patrimônio cultural material e imaterial na Semana Santa de Oliveira/ MG
Authors: Teixeira Matheus Resende , Ribeiro Rafael Winter
Published: January 2024

O estudo aborda a dicotomia entre o patrimônio cultural material e imaterial, destacando a necessidade de políticas públicas para preservá-los. Este artigo foca na Semana Santa de Oliveira, MG, como um caso de análise. A pesquisa procurou identificar como essa festa articula esses dois tipos de patrimônio, considerando os bens culturais reconhecidos pelo município e pelo Instituto Estadual do Patrimônio Histórico e Artístico (IEPHA/ MG). A paisagem festiva foi proposta como um conceito para interpretar essa integração, e o estudo envolveu o mapeamento de bens culturais e a observação da festa. Os resultados mostraram que sete bens culturais materiais estão diretamente envolvidos na festa, incluindo imagens religiosas e edifícios de onde as procissões partem. Outros sete bens culturais indiretos fazem parte dos trajetos das procissões, mas não interagem diretamente com a festividade. A paisagem festiva, que combina elementos materiais e imateriais, desempenha um papel fundamental na festa, mas as políticas de patrimônio cultural tendem a negligenciar essa integração. No geral, o estudo destaca a importância da paisagem festiva como um conceito capaz de articular as dimensões material e imaterial do patrimônio cultural, enfatizando a necessidade de uma abordagem mais integradora na preservação do patrimônio. Esse estudo demonstra como a Semana Santa de Oliveira serve como um exemplo que destaca os desafios e oportunidades de preservação do patrimônio cultural em cidades pequenas, especialmente no que diz respeito à articulação entre os aspectos materiais e imateriais desse patrimônio.

Revista Ciclón: redes de sociabilidade e polêmicas intelectuais durante a ditadura de Fulgencio Batista
Authors: Drummond Caroline
Published: January 2024

Ciclón foi dirigida e editada pelo crítico literário José Rodríguez Feo e pelo escritor Virgilio Piñera entre 1955 e 1959. A revista debatia principalmente a poesia, o papel do intelectual na sociedade cubana e a sexualidade. A concepção de cultura dos editores de Ciclón se baseava na liberdade de criação e de ideias, não se ajustando à “moral oficial”, mas construindo uma cultura que não temeria os temas tabus nem a censura da ditadura de Fulgencio Batista. Neste artigo, analisaremos as redes de sociabilidade intelectual conformadas ao redor da publicação, bem como o editorialismo programático da revista e algumas das polêmicas suscitadas.
A geopolítica na constituição do conhecimento geográfico escolar
Authors: da Silva Rodrigues Cecim Jéssica
Published: January 2024

Este artigo tem o objetivo de refletir sobre a geopolítica no contexto do ensino de Geografia. Metodologicamente, dialogamos com os pressupostos da Teoria do Discurso de Laclau e Mouffe (2015), a partir dos quais interpretamos entrevistas realizadas com professores de Geografia da educação básica de diferentes segmentos e instituições e relacionamos com a bibliografia referente às nossas discussões. Chegamos à noção de que há articulações que são responsáveis por manter as disciplinas escolares nos currículos. No caso da Geografia Escolar, a identificação com a geopolítica, sobretudo em uma relação de contiguidade com os conteúdos de “atualidades”, cumpre esse papel, reafirmando a relevância educacional dessa disciplina escolar. Concluímos que o conceito de território emerge como o grande organizador da construção do conhecimento geográfico escolar a partir dos conteúdos de geopolítica. Neste sentido, as noções escalares igualmente se tornam pertinentes no ensino de Geografia, no qual a relação entre o local e o global é constantemente mobilizada como o grande demarcador da possibilidade de compreensão da realidade social.

No presente artigo apresento os resultados obtidos e as inquietações de uma pesquisa realizada para a dissertação de Mestrado com o tema sobre as Fontes Pedagógicas da Realidade – FPR – e Currículo Regional da Associação de Municípios do Oeste de Santa Catarina – CR Amosc. Esta teve como objetivo geral compreender a importância do Currículo Regional da Amosc e das FPR como caminhos para potencializar a educação geográfica escolar. Para o embasamento teórico utilizei autores da área da Geografia e da educação. Os métodos empregados na pesquisa tiveram base na Hermenêutica-Dialógica, no movimento da Pesquisa Qualitativa, entrelaçando os estudos bibliográficos, documental e empírico, garantindo a análise textual discursiva para interpretar a produção dos professores. Por fim, constatei que as FPR estão articuladas ao CR da Amosc por meio dos planejamentos dos professores e que ainda existem algumas rupturas nos conceitos de realidade e cotidiano que são caros para a educação geográfica. Atribuo, neste artigo, a metáfora de Gaston Bachelard – “A Metáfora da Casa” (2003) –, referenciando nos componentes da pesquisa a estrutura da casa, para que possamos compreender as articulações entre FPR, CR e educação geográfica.

: Com a declaração de emergência sanitária ocorrida em março de 2020, por conta da disseminação do coronavírus, diversos setores da sociedade foram impactados, inclusive, pela implementação de medidas emergenciais que implicaram em um distanciamento social. No âmbito escolar não foi diferente, o principal caminho trilhado para a continuidade das aulas foi por meio do ensino remoto. Nesse contexto, esta pesquisa tem por objetivo compreender as dinâmicas do ensino de Estudos Amazônicos antes, durante e depois da pandemia de COVID-19 nas escolas da rede municipal de ensino na cidade de Altamira – PA, a partir de um diálogo com os professores deste componente curricular. A metodologia utilizada consiste em uma abordagem qualitativa de natureza exploratória, apoiada na revisão de literatura e pesquisa de campo, com a aplicação de questionários aos professores. Constatou-se que os desafios dos sujeitos da pesquisa no âmbito do Ensino Remoto Emergencial foram múltiplos, e que vários deles permanecem, mesmo depois de dois anos letivos, nos quais a presencialidade retornou, além da importância de qualificar a formação do professor de Geografia, que é, em suma, quem responde por este componente de nas escolas paraenses. Defende-se, por fim, a relevância de visibilizar o trabalho docente no âmbito dos Estudos Amazônicos, com pesquisas que busquem compreender as particularidades e a especificidade deste.

Background/Aims: Assessment of quality of magnetic resonance enterography (MRE) in small bowel Crohn’s disease (CD) activity evaluation has received little attention. We assessed the impact of bowel distention and motion artifact on MRE activity indices in ileal CD.Methods: A cohort of patients who underwent contemporaneous MRE and colonoscopy for ileal CD assessment between 2014 and 2021 at 2 centers were audited. An abdominal radiologist blinded to clinical data reviewed each MRE, graded bowel distention and motion artifact upon a pre-specified 3-point scale and calculated the original magnetic resonance index of activity (MaRIA) and simplified MaRIA (sMaRIA), London index and CD MRE index (CDMI). Ileal endoscopic activity was graded via the Simplified Endoscopy Score for CD (SES-CD). The performance of MRE indices in discriminating active disease (SES-CD ≥3) stratified by MRE quality was measured by receiver operator characteristic analyses.Results: One hundred and thirty-seven patients had MRE and colonoscopy within a median of 16 days (range, 0–30 days) with 63 (46%) exhibiting active disease (SES-CD ≥3). Forty-four MREs (32%) were deemed low quality due to motion artifact and/or moderate to poor distention. Low-quality MREs demonstrated reduced discriminative performance between ileal SES-CD ≥3 and MRE indices (MaRIA 0.838 vs. 0.634, sMaRIA 0.834 vs. 0.527, CDMI 0.850 vs. 0.595, London 0.748 vs. 0.511, P<0.05 for all). Individually the presence of any motion artifact markedly impacted the discriminative performance (e.g., sMaRIA area under the curve 0.544 vs. 0.814, P<0.05).Conclusions: Image quality parameters can significantly impact MRE disease activity interpretation. Quality metrics should be reported, enabling cautious interpretation in lower-quality studies.

Bu bağlamda Z Kuşağı da günümüzde büyük ölçüde kamu kesimi hizmet alıcısı veya alt kademelerde çalışan konumunda olsa da, yakın gelecekte kamu yönetiminin bütün kademelerinde yerlerini alacaklardır. Bu nedenle Z Kuşağının mevcut değerlerinin neler olduğu ve gelecekte de hangi değerlerle hareket edecekleri konularındaki çalışmalar önem arz etmektedir. Bu çalışmada literatürde yer alan sessiz kuşaktan alfa kuşağına kadar olan kuşakların yetiştiği atmosferler ve bunların sonucunda ortaya çıkmış olan kuşak değerleri tespit edilmeye çalışılmıştır. Bu kapsamda Z kuşağının değerleri, dünyada yapılmış çok sayıda araştırma kapsamında belirlenerek, kamu yönetimi pratiğine olası etkileri tespit edilmeye çalışılmıştır. Söz konusu etkiler çerçevesinde kamu yönetimi hizmet sunumunda yapılabilecek bir takım yeni düzenlemeler önerilmiştir.

The article presents the experience of using liver elastometry and shear wave dispersion in patients after transplantation, followed by needle biopsy and morphological examination of the organ tissue. The paper shows that the use of elastometry and shear wave dispersion allows one to fairly accurately judge the state of the liver transplant parenchyma and choose the optimal strategy for treatment and management of the patient without performing an invasive procedure — puncture biopsy of the organ.

A clinical case of surgical treatment in patient with tandem ipsilateral lesion of the right internal carotid artery: (95–99 % stenosis at the ostium) and the middle cerebral artery (occlusion) described in the article. Further treatment tactics could be determined with the help of PKT performed on the patient during hospitalization. Changes in the blood supply to the cerebral hemisphere revealed by PKT were of decisive importance in determining the further treatment tactics for this patient. The patient was operated in the range of right side carotid endarterectomy. Control brain tomography perfusion, performed 6 months after surgery, demonstrated the absence of areas with impaired blood flow in the cerebral hemispheres.

Based on the implication that brand image serves as a mediator between social media marketing and purchase decisions, Uniqlo can maximize their social media approach. This could be improved online communication, marketing that tell stories, or the application of unique social media platform characteristics that improve brand perception. This study aims to investigate the relative influence of social media marketing, product quality, and brand image on purchasing decisions. The research design chosen was causal research with purposive sampling technique. A questionnaire given to participants who met the requirements was used in this study. In this survey, a 5-point Likert scale was used (1 meaning strongly disagree and 5 meaning strongly agree). The large sample collected and surveyed in this research consisted of 200 respondents. The samples involved were Uniqlo consumers based in Indonesia. Structural Equation Modeling (SEM) with the AMOS 24 statistical tool will be used to construct and assess the measurement model and structural model of the research design. This research has shown how social media marketing, product quality, and brand image all have a big relationship on consumers' purchase decisions to buy, both on direct influence or indirect influence mediated by brand image.
Code-Switching in French and Francophone Studies Classrooms in a Ghanaian Public University: Exploring Perceptions and Motivations
Authors: Abban Albert , Mensah Dorah , ResCue Elvis
Published: January 2024

Code-switching in language classrooms is a contentious topic of debate, with some experts advocating for the monolingual use of the target language as the medium of instruction, while others support a bilingual approach such as code-switching and translanguaging. This paper examines the motivations for code-switching and the perceptions of both lecturers and students on bilingual practices in French and Francophone Studies classrooms. The study adopted a mixed research design, gathering data through interviews, classroom observation and an online questionnaire using a Google Form interface. The questionnaires were distributed to students via their WhatsApp platforms. A total of 120 French students filled out the questionnaires and 5 lecturers were selected for the interview session. The findings revealed that lecturers employ code-switching to address the linguistic needs of both Anglophone and Francophone students in the classrooms. The reasons for code-switching included students’ limited language background, low proficiency in the French language, inadequate teaching materials, situational factors, and the relevance of other languages in French classrooms. Overall, the majority of the lecturers and students expressed a positive perspective towards code-switching use in the classroom stating that such code choices facilitate the understanding of concepts and contribute to interactive classroom experiences. There was, however, the caution against its pervasive use as it hinders the ability to learn and speak the French language.
A Brief Historic Review of Special Education for Students with Extensive Support Needs in the US, Hawai’i, and Japan
Authors: Matthews Somer
Published: January 2024

The purpose of this paper is to provide a scoping review situating the history of special education for students with extensive support needs (ESN) in the United States and Hawaii, as well as in Japan and other parts of East Asia. With the continued globalization of our interactive world, none of our educational systems exist in a vacuum; our systems have and will continue to influence one-another. This influence is evident throughout the literature, showing that though the timing of special education reform in each of these regions differ, many parts of our educational systems mirror one another. Despite our differences, what we all share is a common goal of reducing the stigmatization of students with disabilities in our schools and societies, and we will only achieve that through a global shift toward presumed competence.
Game Analysis of Product Supply Chain Considering Lead Time Compression and Demand Forecast Information Updating
Authors: Lemoine Bizimana
Published: January 2024

In a supplier-led decentralized decision-making second-level supply chain, consideration can compress lead times and update demand forecast information. This paper discusses the order volume decision of the retailer and the lead time and wholesale price decision of the supplier, analyzes the interaction between the retailer and the supplier's decision and the influence of the cost of lead time reduction on the retailer and the supplier's decision. The results show that the optimal order quantity of retailers is low in equilibrium, which leads to the service level of supply chain is less than 50% and the lead time of supply chain is too long. Encouraging retailers to increase order quantity is the key to improve supply chain service level and reduce supply chain lead time. Reducing the lead time and reducing the cost can not only enable retailers to increase the order quantity, improve the service level of the supply chain to the market demand, but also enable suppliers to reduce the order lead time and improve the response speed of the supply chain to the market demand.
Examining Foreign Language Teaching Anxiety in a Saudi University

Published: January 2024

This study examines the foreign language teaching anxiety (FLTA) faced by EFL teachers in the Saudi context. Moreover, it aimed to investigate the relationship between teachers’ gender and years of experience with their perceived level of FLTA. The study employed a quantitative method and used an adaptive version of FLTAS by Ipek (2006). The participants were 97 EFL teachers working in a Saudi university in Jeddah. The results indicate that the participants experienced a low level of FLTA. The findings also demonstrate a significant relationship between teachers’ level of FLTA and both their gender and years of experience. Male EFL teachers were found to experience more teaching anxiety than female teachers. Furthermore, EFL teachers with more than 10 years of experience faced lower FLTA levels than the other teachers. The findings of this study provide an insight of FLTA in the Saudi context and some recommendations for further research development.
On Raptus, Quitclaims, and Precedents in Staundon v. Chaucer–Chaumpaigne: An Afterword
Authors: Roger Euan , Sobecki Sebastian
Published: January 2024

The two documents we presented in The Chaucer Review 57.4 (2022) changed everything we knew about Chaucer’s relationship with Cecily Chaumpaigne. We showed that in this case raptus does not refer to rape or violent crime but to procurement in the form of poaching a servant, an action made illegal by the Statute and Ordinance of Laborers (1349/51). The new records clarify that Chaucer and Chaumpaigne were co-defendants not opponents, being sued together by Thomas Staundon, Chaumpaigne’s former employer. The present article explains in greater depth how Chaumpaigne’s two quitclaims are concerned with procurement, not rape or abduction, and labor law. This article also introduces precedents and analogues, demonstrating that medieval lawyers might regard the procurement of an employee under the Statute of Laborers to amount to raptus custodie, or ravishment of ward. Finally, we suggest that the case of Staundon v. Chaucer–Chaumpaigne belongs to the long history of the noncompete clause.
Septic Peritonitis Secondary to Neoplasia in Two Canine Cancer-Bearing Patients Lacking Gastrointestinal and Hepatic Organ Rupture
Authors: Gualtieri Patricia , Saavedra Paulo Vilar
Published: January 2024

In this case report, we describe the presentation, diagnosis, and outcome of septic peritonitis secondary to neoplasia in patients lacking evidence of gastrointestinal content leakage, liver abscessation, or other treatment-associated risk factors. Two dogs presented with a diagnosis of neoplasia and nonspecific clinical signs such as lethargy, hyporexia, vomiting, and discomfort that was localized to the abdomen. The diagnoses at presentation consisted of a perianal tumor consistent with apocrine gland anal sac adenocarcinoma and systemic mastocytosis. Neither of the dogs was considered systemically immunocompromised or had received recent cytotoxic chemotherapy treatment or surgical procedures. A common finding on blood work in the two dogs was the presence of band neutrophils. The diagnosis of septic peritonitis via fluid analysis and cytology was delayed in both cases. No treatment for the supposed underlying cause of septic peritonitis was pursued and euthanasia was pursued in both cases owing to poor prognosis. On necropsy, one dog was suspected to have developed septic peritonitis because of an abscessed lymph node, and in the other case, no definitive source was identified. Septic peritonitis can arise secondary to neoplasia that is not primarily involving the liver or gastrointestinal tract in canine patients that lack treatment-associated risk factors.

Pacjent z chorobą koronawirusową 2019 (COVID-19) w szpitalu tymczasowym zaprezentował objawy nagłej niewydolności oddechowej, co w badaniach obrazowych wskazywało na odmę opłucnową jako przyczynę. Interwencja torakochirurgiczna, polegająca na drenażu jamy opłucnej, początkowo przyniosła pożądany efekt, ale tylko na krótki czas. W kolejnych dniach powstały nowe komory odmy opłucnowej wymagające drenażu, jak się okazało w tomografii komputerowej, z powodu pneumatocele. Drenaż zagrażającej życiu odmy opłucnowej jest minimalnie inwazyjną i wystarczającą procedurą leczenia COVID-19, a tomografia komputerowa powinna być standardem w przypadku objawów niewydolności oddechowej u już zdrenowanych pacjentów.
