Authors: Malta Guilherme Augusto Pereira , Fois Braga Humberto , Almeida Luisa Antunes , Moreira Alexia de Freitas Garcez , Da Silva Gomes Ayla 
Published: November 2024

O presente estudo buscou compreender como a paisagem da Terra Média, presente na obra do escritor J. R. R. Tolkien, é transposta semioticamente das linguagens narrativas da literatura e do cinema para a cenarizada, tematizada e habitável do turismo, sobretudo como meio de hospedagem que se torna uma experiência de imersão do hóspede em um mundo possível ficcional. Para tanto, foram realizados, em sites de hospedaria, levantamentos de hospedagens temáticas durante o período de novembro de 2022 a abril de 2023 e, posteriormente, optou-se pelo foco nos meios de hospedagem do Brasil. Para auxiliar nas análises, o campo do Turismo e da Geografia foram essenciais, além do campo da Literatura e Narratologia. Para melhor compreensão dos dados, foram elaborados tabelas e gráficos. A partir da concretização das etapas, notou-se, em meio aos resultados, como a topografia local pode interferir diretamente na facilidade para possuir um posicionamento geográfico similar ao da Toca Hobbit. Além disso, constatou-se que há uma questão estruturante e limitante relativa às possibilidades dos códigos de linguagem específicos para cada um dos diversos sistemas representacionais. Ou seja, há clara complexidade e dificuldade na transposição do texto bidimensional para a realidade ancorada no mundo concreto e que enfrente a escassez de recursos físicos, espaciais e econômicos. Por fim, entende-se o potencial que este trabalho apresenta ao desenvolver um método que dá visibilidade à “tematização paisagística” enquanto construtora de experiências, contribuindo na implementação de uma atração turística pautada na “hospitalidade de mundos possíveis ficcionais". Do ponto de vista prático, a pesquisa buscou auxiliar futuros empreendedores a utilizarem novos parâmetros para concepção de projetos de hospedagem tematizadas, tendo como base o imaginário de Tolkien e o universo fantástico das Tocas Hobbit.

Страницы истории журнала «Искусство и художественная промышленность» (1898–1902)
Authors: Грачева Светлана Михайловна 
Published: November 2024

Аннотация
Журнал «Искусство и художественная промышленность» издавался с 1898 по 1902 гг. и начал выходить почти одновременно с известным журналом «Мир искусства». Редактором журнала был Н. П. Собко. До недавнего времени журнал «Искусство и художественная промышленность», во многом из-за участия в нем В. В. Стасова, оценивался как довольно консервативный, связанный с эстетикой XIX века, не выполнивший возложенную на него миссию новаторского издания. Благодаря последним исследованиям по истории русской журналистики, библиографии и критики, мнение о журнале изменилось. Его стали оценивать как эстетический феномен, имеющий много ярких художественных качеств. В статье на основе архивных материалов и переписки рассматривается история журнала, выявляется роль Н. П. Собко и В. В. Стасова в нем, анализируются наиболее значимые публикации, сделанные в этом издании. В статье с опорой на архивные материалы воссоздается цельная картина возникновения журнала и характеризуется деятельность основных фигур, связанных с ним. Благодаря сохранившимся документам можно определить место и роль журнала в истории русской культуры.
Gradient bounds and Liouville property for a class of hypoelliptic diffusion via coupling
Authors: Qian Bin , Zhang Beibei 
Published: November 2024

Abstract
In this paper, we obtain the reverse Bakry–Émery-type estimates for a class of hypoelliptic diffusion operator by coupling method. The (right and reverse) Poincaré inequalities and the (right and reverse) logarithmic Sobolev inequalities are presented as consequences of such estimates. Wang–Harnack inequality, Hamilton’s gradient estimate and Liouville property are also presented by the reverse logarithmic Sobolev inequality.

Which factors predict teachers’ evaluation of the difficulty and usefulness of phrasal verbs in L2 contexts?
Authors: Sonbul Suhad , El-Dakhs Dina Abdel Salam 
Published: November 2024

Abstract
Research examining teachers’ cognition of lexical items has flourished in the past few years. However, most of these studies focused on individual words rather than formulaic sequences. The present study aims to fill this gap through eliciting teachers’ evaluation of one type of formulaic sequences: phrasal verbs (PVs). The aim is to examine factors (frequency, opacity, and learners’ receptive and productive knowledge) that might predict teachers’ evaluation of the difficulty and usefulness of 100 PV senses. For that purpose, a survey was administered to 174 teachers. Results of generalized mixed-effects modelling showed that teachers’ assessment of both the usefulness and difficulty of PVs was predicted by sense-specific corpus frequency and receptive knowledge of these PV senses. Moreover, difficulty ratings were additionally affected by opacity and productive knowledge of PVs. We discuss these findings in relation to previous research on L2 PV knowledge and implications for L2 teaching practice.

Collective Management of Environmental Resources: Historical-Anthropological Insights from the Slovenian Karst (19th century to post-socialism)
Authors: Beltrametti Giulia 
Published: November 2024

Abstract
This paper presents the first results of a two-year interdisciplinary research project on the collective management of environmental resources in the Slovenian Karst region from the 19th century through the post-socialist era. Utilizing both anthropological fieldwork and historical archival research, the study explores the historical continuity and discontinuity of local agrarian communities’ practices in managing forests, land and pastures. The research emphasizes the socio-legal capacity of these communities to produce, claim, and negotiate rights amidst varying administrative and political regimes, from the Habsburg Empire to independent Slovenia. The study also compares similar cases in other Eastern European post-socialist countries, highlighting the complex dynamics of re-socialization and ownership morphologies. The findings suggest that a nuanced understanding of the historical and social contexts is crucial for interpreting the collective management of natural resources, with implications for current and future resource accessibility and sustainability.

AbstractSimilar to other regions, in East Central Europe, agriculture is the most vulnerable sector regarding the consequences of climate change through increasing variability in weather conditions, even on the short-term and local scales. Agricultural engineers make decisions; higher education has a crucial role in taking proper actions. Our survey aimed to get up-to-date information on the knowledge and attitude of graduating students completing agriculture-related studies at 6 universities located in Hungary, the Czech Republic, Poland, and Slovakia, with particular attention to weather projections, crop production, and soil protection issues. Analyses revealed adequate lexical knowledge of young engineers in each country. They are familiar with the agro-environmental actualities and future trends, issues to address at the right time, and the repertoire of tools and practices for taking efficient measures. A positive attitude toward proactive actions was proved. We report proof of a high level of preparedness resulting from the proper efficacy of agricultural higher education. The content of the curricula and the teaching methodologies meet well the receptiveness to learning in the V4 countries. Our findings confirm that frequent updating of the content of subjects as well as incorporating practical applications that promote active learning and engagement, are more critical today than ever, and it is possible to achieve a high level of preparedness for the challenges in the agricultural sector.
Analysis and Evaluation of Recent Deformation on the Huaytapallana Fault (Central Region of Peru) Based on Data Obtained from a Local Seismic Network
Authors: Tavera Hernando , Nina Vilma , Bernal Isabel Yesenia , Mercado Arturo 
Published: November 2024

Abstract
In the central region of Peru, two earthquakes with magnitudes of Ms 5.6 and 6.2 occurred in 1969, originating from the Huaytapallana fault. As a result, two fault scarps formed on the surface: the first measuring 4 km and the second one 9.5 km in length, separated by a 4 km section without a surface scarp. A three-year seismic campaign (2015–2018) conducted around the Huaytapallana fault has provided insights into its current dynamics. The 172 microearthquakes recorded, with magnitudes ranging from Mw 0.6 to 3.1, are distributed along the northeastern flank of the fault and extend over 40 km, including segments without visible surface scarps. The Huaytapallana fault is estimated to have a depth of around 15 km with a dip of 60° toward the northeast. The composite focal mechanisms indicate a deformation process due to compression, with a fault plane oriented in the north-northwest–south-southeast direction and dipping toward the northeast at angles between 55° and 60°. The Mw 4.7 earthquake in 2022 and its series of aftershocks exhibit a similar deformation pattern associated with the Huaytapallana fault. These results are consistent with the regional tectonics, which control the deformation processes in the Mantaro basin, originating from the convergence of the Nazca and South American plates. We consider that the significant microseismic activity occurring in areas without visible surface scarps suggests the accumulation of substantial deformation, which could lead to future earthquakes of greater magnitude that may cause significant surface displacements.
LA DEFINICIÓN DE LA FUENTE EN LA ERA DE LOS NÓMADAS TRIBUTARIOS
Authors: Jijón Ignacio , Zumba Barbosa Miguel Ángel , Cabrera Hidalgo Paula , Bermeo José Elías , Cadena Herrera Ana Belén 
Published: November 2024

Los nómadas tributarios constituyen uno de los retos más complejos que enfrenta la fiscalidad internacional. Partiendo desde su concepción más básica, los sujetos que se encasillan en esta categoría carecen de un lugar estable de residencia tributaria. Por lo tanto, la fórmula para someter a imposición los ingresos del nómada tributario sobrepasa las tradicionales definiciones locales de fuente y de residencia; y sugiere la necesidad de alcanzar un acuerdo internacional para someterlos a tributación bajo una aproximación a una fuente global concertada, que podría estar vinculada al criterio de la nacionalidad o a la presencia económica significativa.

El presente trabajo aborda esta problemática bajo una óptica de fiscalidad internacional, con un especial énfasis en los impactos que el fenómeno de los nómadas tributarios tiene para los países latinoamericanos.

Deceptive Point-of-Sale Marketing Tactics Impact on Consumer Purchase Intentions with an Attitude as a Mediator
Authors: Massoudi Aram , Jalal Fatah Sahar 
Published: November 2024

The study examines how misleading sales techniques, such as deceptive point-of-sale practices, affect customers' willingness to buy things or their purchase intention in Iraq, where laws protecting consumers are weak and uncontrolled. The researchers also looked at how a customer's overall impression (attitude) of a product plays a role in this connection. The surveyed 400 shoppers at various supermarkets in Erbil, Iraq. 382 valid responses were received. A Partial least squares structural equation modeling (PLS-SEM) was used to analyze the data and test the study's hypothesis. The findings show that deceptive sales tactics hurt a customer's desire to buy. Additionally, a customer's perspective on a product plays a part in the link between those tactics and purchase intention. These results suggest that honest marketing practices benefit both businesses and customers by creating positive feelings towards products and ultimately increasing sales.

Resilience to Abrupt Global Catastrophic Risks Disrupting Trade: Combining Urban and Near-Urban Agriculture in a Quantified Case Study of a Globally Median-Sized City
Authors: Boyd Matt , Wilson Nick 
Published: November 2024

Abstract

Background
Abrupt global catastrophic risks (GCRs) are not improbable and could massively disrupt global trade leading to shortages of critical commodities, such as liquid fuels, upon which industrial food production, processing and distribution depends. Previous studies have suggested urban agriculture as a resilience measure in the context of climate change and other natural hazards.
Aims
To estimate the contribution a radical pivot to urban agriculture could have in building resilience to GCRs and the near-urban industrial agriculture needed to supplement urban food production.
Methods
We determined optimum crops by food calorie and protein per area for urban and near-urban agriculture. We calculated the land area available for food production within a temperate globally median-sized city using Google Earth image analysis of residential lots and open city spaces. We calculated the population that could be fed through urban agriculture alone, and the extra near-urban land required for cropping with industrial agriculture to feed the remaining city population, under both normal climate, and potential nuclear winter conditions.
Results
Peas (normal climate), and sugar beet/spinach (nuclear winter) were the optimal crops for urban agriculture, with potatoes (normal climate), and wheat/carrots (nuclear winter) optimal for industrial near-urban production. Urban agriculture could feed 20.4% of the population. At least 1140 hectares of near-urban cultivation could make up the shortfall. Another 110 hectares of biofuel feedstock like canola (rapeseed) could provide biodiesel to run agricultural machinery without fuel trade. Significantly more cultivated area is needed in nuclear winter scenarios due to reduced yields.
Conclusion
Relatively little optimized near-urban industrial agriculture, along with intensified urban agriculture could feed a median-sized city in a GCR, while minimizing fuel requirements. Governments and municipal authorities could consider land use policy that encourages development of urban agriculture and near-urban cultivation of optimal crops, along with processing and local biofuel refining capacity.
Using additive manufacturing to transition away from OEM-repaired failures: a protection-level preservation constrained life-cycle cost model
Authors: Chen Shao-Peng , Sandborn Peter , Rovere Tom 
Published: November 2024

Abstract

Additive manufacturing (AM) provides many potential benefits over conventional manufacturing (CM) for critical systems. This paper is focused on quantifying the value of the possible time savings associated with AM when supporting a fleet of critical systems. The model developed in this paper focuses on systems that currently use CM and need to be returned to their original equipment manufacturer (OEM) for repair when they fail; AM allows some failures to be resolved without requiring return to the OEM and thereby reduces the spare resupply time. The model monetizes the cost avoidance associated with using AM parts based on a constraint that the protection level provided by a spare subsystem inventory for a fleet utilizing conventional manufacturing (CM) parts equals that of a fleet employing AM parts. Protection level is the probability that at least one spare will be available in the inventory all the time. Models for single-echelon and multi-echelon sparing are developed. A case study of an Electronic Support Measures (ESM) system used in helicopter fleets deployed on aircraft carriers is provided. The results of the case study demonstrate that although manufacturing costs are larger when using AM parts, the life-cycle cost for a fleet of systems can be substantially less due to decreases in failure resolution times enabled by AM part repairs in the field.
