ANALYSIS OF STUDENT ERRORS IN SOLVING QUESTIONS ON A SYSTEM OF LINEAR EQUATIONS WITH TWO VARIABLES IN CLASS VIII SMP NEGERI 2 SOMAMBAWA SCHOOL YEAR 2022/2023
Authors: Hulu Lukas Jaya
Published: November 2023

This research is motivated by the existence of errors that students often make in solving mathematics problems. This research aims to describe students' errors in solving systems of two-variable linear equations. The subjects in this research were 24 students in class VIII of SMP Negeri 2 Somambawa for the 2022/2023 academic year. The data was analyzed using steps, namely data reduction, data presentation and drawing conclusions. The research data collection techniques used were tests and interviews. The results of the research show that students still make mistakes in solving problems on systems of linear equations in two variables. This results in students not being able to identify known data and the data asked for in the question. Students do not master mathematical calculation operations so they often make mathematical calculation errors. Apart from that, this error is also caused by students' lack of accuracy when carrying out mathematical calculations. So it was concluded that these errors included errors in organizing data for 13 students with a percentage of 54%, procedural errors and errors for 15 students with a percentage of 62%, and errors in drawing conclusions for 18 students with a percentage of 75%. Researchers suggest that mathematics teachers should provide students with more frequent exercises in solving systems of linear equations in two variables, especially in multiplication and subtraction operations, and division that is not divisible.

Authors: Roth Anne-Christin , Stamm Lara
Published: November 2023

Insbesondere Sportlehrkräfte standen während des pandemie-bedingten Distanzunterrichts vor großen Herausforderungen bei der Unterrichtsgestaltung. Auf Basis der Fachkulturtheorie und unter Einbezug der empirischen Befunde zu Orientierungen von Sportlehrkräfte sowie der internationalen und nationalen Forschungslage zu Sportunterricht während COVID werden im Beitrag die Denk-, Wahrnehmungs- und Handlungsmuster von Sportlehrkräften in den Blick genommen. Damit zielt der Beitrag in Anknüpfung an eine eigene inhaltsanalytische Studie auf die Rekonstruktion von Orientierungsmustern der Sportlehrkräfte in Bezug auf den Sportunterricht in Präsenz und auf Distanz ab. Aus einem gesamten Sample von 66 Interviews mit Sportlehrkräften aller Schulformen in NRW konnten neun Interviews kontrastiv ausgewählt werden, die entlang der dokumentarischen Methode ausgewertet wurden. Es wurden drei Orientierungstypen rekonstruiert, die sich zwischen den Polen Bewegungs- und Beschulungsorientierung verorten lassen. Die empirischen Ergebnisse werden abschließend hinsichtlich ihrer Stabilität trotz gravierender Veränderungen der Organisationsformen im Rahmen der Umstellung auf Sportunterricht auf Distanz diskutiert.
Beschämungen im inklusiven Sportunterricht. Eine explorative Studie
Authors: Zankl Felicitas , Giese Martin
Published: November 2023

Der Beitrag verfolgt das Ziel, subjektive Schamerfahrungen von Schüler:innen im inklusiven Sportunterricht zu rekonstruieren. Dazu werden fünf Schüler:innen mit und ohne sonderpädagogischem Förderschwerpunkt Geistige Entwicklung aus einer Realschule sowie einer Gemeinschaftsschule befragt. Die Ergebnisse zeigen, dass Scham eine bedeutsame Rolle im Sportunterricht spielt. Dabei wurden vor allem die Kategorien Leistungsdruck, Intimitätsverletzungen, Beleidigungen und Demütigungen, öffentliche Bloßstellung, körperlich-konstitutionelle Voraussetzungen und mangelnde sportspezifische Fertigkeiten für das Entstehen von Scham benannt. Es zeigte sich, dass die Ergebnisse vorhandene sportpädagogische Erkenntnisse bestätigen und wenige Unterschiede zwischen einer inklusiven und einer nicht-inklusiven Sportklasse hinsichtlich der Schamerlebnisse festgestellt werden können. Dort, wo sich Unterschiede zeigen, scheinen die Auswirkungen negativer Art zu sein und in erster Linie die Schüler:innen mit Behinderung zu betreffen.
Die Rolle des Europäischen Gerichtshofs im Wandel
Authors: Lang Lea Isabelle
Published: November 2023

The thesis examines the changing role of the ECJ in the course of its judicial activity. While some of the early "grands arrêts" of the ECJ sometimes made it seem like an activist court that developed Community law in pursuit of "a certain idea of Europe", without regard to national interests and legal doctrines, its case law now increasingly displays a tendency towards restraint and minimalism. These trends are analysed in the thesis. It focusses on the increased scope for decision-making granted to the judiciaries of the Member States, and examines the possible causes, benefits, and risks of this decentralization of control over EU law.

Published: November 2023

Abstract. In this study, the out-of-plane failure mechanism of medium-sized masonry panels, which is frequently encountered during earthquakes, is discussed. Four of 100 mm x 410 mm x 1200 mm masonry panels were fabricated for the experimental study. Solid brick with dimensions of 50 mm x 100 mm x 200 mm was used in the production of the masonry panels. For mortar, repair mortar was used for ease of production. Three of the test specimens were strengthened with carbon fiber reinforced polymer (CFRP). The number of strips and the way of applying strips were adopted as test parameters. Panel specimens were tested under the effect of bending, applying three- point loading. During the experiments the measurements of load, displacement and strain were taken. Behaviour of the masonry panels were assessed in terms of ultimate load, the displacement corresponding to the ultimate load, stiffness and energy dissipation capacity. According to the results obtained, it is concluded that the strengthened masonry panels are quite successful against the out-of-plane failure mechanism.

Authors: Trejnowska Ewa , Nożyński Jerzy K. , Jankowski Miłosz , Brożek Grzegorz , Skoczyński Szymon , Swinarew Andrzej S. , Lange Dariusz , Knapik Piotr
Published: November 2023

Context.—

Extracorporeal membrane oxygenation (ECMO) is increasingly used in the treatment of respiratory and cardiac failure, but data describing lung histopathology in ECMO recipients are limited.

Objective.—

To examine pulmonary histopathologic findings in patients who underwent venovenous (VV) ECMO for pulmonary reasons or venoarterial (VA) ECMO for cardiac indications shortly before death, and to determine if the pulmonary changes provided insights into therapy that may prevent complications and improve outcome.

Design.—

We conducted a retrospective study of lung autopsies, from VV and VA ECMO recipients and patients with acute respiratory distress syndrome (ARDS) and non-ECMO treatment, between 2008 and 2020 in Silesia Center for Heart Diseases in Zabrze, Poland.

Results.—

Among 83 ECMO patients (42–64 years; men, 57 [68.7%]), the most common histopathologic findings were bronchopneumonia (44 [53.0%]), interstitial edema (40 [48.2%]), diffuse alveolar damage (DAD; 32 [38.6%]), hemorrhagic infarct (28 [33.7%]), and pulmonary hemorrhage (25 [30.1%]). DAD was associated with longer ECMO treatment and longer hospital stay. The use of VV ECMO was a predictor of DAD in patients with ARDS and undergoing ECMO, but it also occurred in 21 of 65 patients (32.3%) in the VA ECMO group, even though VA ECMO was used for heart failure.

Conclusions.—

Although DAD was significantly more common in lung autopsies of VV ECMO patients, one-third of VA ECMO patients had histopathologic changes characteristic of ARDS. The presence of DAD in lung autopsies of patients treated with VA ECMO indicates that in these patients, protective lung ventilation should be considered.

How has COVID-19 influenced changes in a platform business model of a startup? Alloy’s case study
Authors: Zuquetto Rovian Dill , Molling Graziela
Published: November 2023

Purpose – This study aims to identify the changes in a startup’s platform business model (PBM) due to COVID-19, considering the properties of value proposition, value creation, and value capture in three periods: Pre-COVID-19, During COVID-19 and almost Post-COVID-19.
Design/Methodology/Approach – This inductive qualitative research is based on a longitudinal and single case study of Alloy, a Brazilian startup that had to change its PBM due to the COVID-19 pandemic. Primary data was collected through interviews, complemented by secondary data such as documents and videos. Data collected refers to the period from August 2019 to July 2023. Data analysis was conducted following the content analysis approach.
Findings – Due to the COVID-19 scenario, Alloy had to change its PBM by modifying its value proposition, value creation, and value capture, moving the focus from a transaction platform to an innovation platform. While scalability decreased due to COVID-19, the PBM changes allowed Alloy to increase its network externalities, which can influence return to scale and bring it closer to success with PBM.
Research limitations/implications – As a limitation, this study focuses on a single case study. Although it is singular, new cases can help to support our findings.
Originality/Value – The originality of this study relies on being able to follow the steps of a startup with a PBM during the COVID-19 period. In complement, a conceptual model was developed to identify Alloy’s changes and opportunities to succeed with its PBM, which can be helpful for academics and practitioners.
A experiência de cegueira induzida e a percepção espacial-temporal no desenho cego
Authors: Kupstaitis Bethielle Amaral
Published: November 2023

A partir da experiência de criação de desenhos cegos nasce este estudo baseado em reflexões acerca da prática artística. Na experiência de cegueira induzida, debruça-se sobre a percepção espacial e temporal compreendida no fazer. A predominância da percepção temporal frente à desorientação da percepção espacial conduziu à busca de relatos do neurologista Oliver Sacks quanto à formação da percepção de pessoas cegas que retomam ou não a visão. Estabelece-se então um paralelo sobre a percepção da cegueira induzida e o modo como a realização da série de desenhos cegos é conduzida. O conceito de “contemporâneo” de Giorgio Agamben auxilia a pensar na escuridão dos olhos vendados como uma forma de ser plenamente ativo. Reconhece-se neste não-ver a capacidade de tornar desperto e ativar a atenção para o momento presente, ao oferecer a possibilidade de perceber o tempo e o espaço de forma alargada e intensa.
Narrativas de uma cidade em ruínas: caminhando com paisagens, educações e alianças multiespécies
Authors: Linhares Marcos Allan da Silva , Lourenço Keyme Gomes , Estevinho Lúcia de Fátima Dinelli
Published: November 2023

Este ensaio, escrito ao modo narrativo e experimentativo, procura flagrar alianças que emergem do espaço urbano e que interseccionam natureza-cidade-educação, compondo paisagens multiespécies que nos mostrem caminhos possíveis para pensarmos educações-outras. Para criar uma escrita em experimentação fizemos alianças epistemológicas com as antropólogas Anna Tsing e Donna Harawaye com trabalhos do campo da filosofia da diferença de Deleuze e Guattari. Dessa forma esse trabalho foi tecido como se caminha por aí, atravessando as dobras da cidade, nas vielas ora de cimento, ora de palavras. Caminhamos com o corpo ao subir e descer ruas, produzíamos uma conversa contínua entre nós e os seres das cidades, humanos e não-humanos. Esses encontros foram disparadores potentes para a criação de narrativas que se expressam através de imagens, textos, grafias, contos, enredos que compõem aquilo que nos marcou e nos fez vibrar pelo caminhar. A caminhada como método para produção de narrativas de uma cidade em ruínas, nos abre a possibilidade de conhecer e também de participar de negociações que produzem as paisagens-multiespécies na cidade. Produzir narrativas que permitem serem permeadas pelo fluxo de devir-escrita-caminhar significa atentar-se enquanto pesquisadores-professores-artistas a escutar mais do que falar, de tornar-se acolhedor daquilo que é pequeno e passa despercebido, de reaprender a todo momento, de expor-se aos inesperados das descobertas que vão ecoar não dos grandes prédios, mas sim daquilo que estará entre eles, nas frestas que eles deixam na composição da paisagem que são preenchidas e arrochadas pelos habitantes humanos e não-humanos.

A shift in values is needed to address climate change impacts affecting communities and the environment in the Philippines
Authors: Dalhog Ma. Isabel
Published: November 2023

This feature essay explores the intricate symbiotic link that exists between human values and the planet's resources. It emphasizes the crucial relationship between human survival, economic growth, and environmental preservation. The Philippines, a country blessed with immense biodiversity, is highly reliant on natural resources for subsistence, livelihood, and well-being. The Philippines is at serious ecological risk due to unsustainable practices, particularly in the field of marine ecology. The growing threat of climate change only serves to intensify this approaching ecological disaster. The weight of addressing these challenges ultimately falls upon the shoulders of the youth, who will bear the consequences of the acts of the current generation. The paper highlights the importance of human activity in causing climate change impacts and emphasizes the urgent necessity for societal values to change in order to prevent looming environmental crises. It issues a compelling call to action, urging individuals and society as a whole to recognize their shared responsibility in minimizing the adverse impacts of climate change. Educational institutions stand out as significant catalysts for change, boosting environmental awareness and developing sustainable behaviors. The essay highlights the moral and just aspects of climate responsibility and the need for governments to take preventive action. The essay concludes that there is a need for collaborative, united efforts in the Philippines to safeguard and conserve the environment as a crucial prerequisite for a sustainable future to mitigate climate change impacts.
Was hinter dem Kapitalismus steckt
Authors: Derndorfer Judith , Witzani-Haim Daniel
Published: November 2023

In ihrem jüngsten Werk "Der Allesfresser" (auf Englisch erschienen als "Cannibal Capitalism") wirft die renommierte marxistische US-Philosophin Nancy Fraser einen strukurellen und historischen Blick auf den Kapitalismus. Fraser definiert den Kapitalismus als ein Gesellschaftssystem, das für sein Funktionieren mehrere „verborgene Stätten“ ausbeuten muss: durch rassistische und imperialistische Enteignung, in der Sphäre unbezahlter sozialer Reproduktion, in seinem Verhältnis zur Natur, durch das der Kapitalismus den menschgemachten Klimawandel verursacht, sowie durch die Aneigung politischer Macht und Governance. Abhilfe schaffen kann nur ein Antikapitalismus, der politische Kämpfe in all diesen Sphären verbindet und einen neuen Sozialismus des 21. Jahrhunderts hervorbringt.

Published: November 2023

Die Ressource Zeit birgt das Potenzial, Normen und Machtstrukturen zu hinterfragen. "Alle_Zeit" rückt den gesellschaftlichen Stellenwert von Zeit in den Fokus und diskutiert die Ungleichheiten von Zeit(en). Die Diagnose: Unsere Zeitkultur und die Norm des 8-Stunden-Erwerbsalltags unterdrückt andere Zeiten, wie Care, Freizeit, politische Partizipation und zivilgesellschaftliches Engagement. Gezielte zeitpolitische Maßnahmen tragen zu einem Bewusstsein für die Infragestellung dieser Normen bei und schaffen mehr Zeitgerechtigkeit und gesellschaftlichen Zusammenhalt. Der Beitrag sorgt für wesentliche Anknüpfungspotenziale an den öffentlichen Diskurs um (Erwerbs-)Arbeitszeitverkürzung.
Checking a conclusion we made in 1987: Tetrahedral intermediates formed by nitrogen and oxygen attack of aromatic hydroxylamines on acetyl cyanide
Authors: Rzepa Henry
Published: November 2023

Minds (and memories) can work in wonderful ways. In 1987[1] we were looking at the properties of “stable” tetrahedral intermediates formed in carbonyl group reactions. The reaction involved adding phenylhydroxylamine to acetyl cyanide. NMR signals for two new species were detected, and we surmised one was due to N-attack on the carbonyl and one was due to O-attack, in each case to form a stable tetrahedral intermediate.
Translating Identifiers
Authors: Winston Donny
Published: November 2023

Good identifiers are opaque, so translation is by association – owl:sameAs, skos:exactMatch, or some other relationship. Translation doesn’t follow from reading a sign, but from retrieving a sense. If metadata is relationships between identifiers,1 then metadata is the medium of conceptual convergence.
Tracing Identifiers
Authors: Winston Donny
Published: November 2023

At a base level, an identifier is simple to trace – it is the sequence (modulo concurrency) of assertions of which it is a part. In fact, this can be the basis for tracing the representation of a “thing” as the flock of relationships between identifiers, i.e. metadata, that waxes and wanes in association with “the” identifier of the thing.
Indexing Validators

The Citation Style Language (CSL) team is happy to announce CSL 1.0.1. CSL 1.0.1 is an (almost completely) backwards compatible release, and CSL 1.0 styles and locale files don’t have to be updated to work with CSL 1.0.1-compatible software. CSL 1.0.1 is a relatively minor update, but adds a variety of new features to CSL, and an extra layer of polish to both the specification and schema.
Diberyllocene — and Lithioborocene?
Authors: Rzepa Henry
Published: November 2023

Sometimes, the properties of a molecule are predicted long before it is synthesised. One such is diberyllocene. I first encountered a related molecule, beryllocene itself, many moons ago.[1] This was unusual because unlike the original metallocenes, the metal atom was not symmetrically disposed between the two cyclopentadienyl faces.

Sometimes you come across a reaction which is so simple in concept that you wonder why it took so long to be accomplished in practice.
A new type of bispericyclic reaction: Cyclopropanone + butadiene.
Authors: Rzepa Henry
Published: November 2023

The term bispericyclic reaction was famously coined by Caramella et al in 2002[1] to describe the unusual features of the apparently innocuous dimerisation of cyclopentadiene. It shows features of two paths for different pericyclic reactions, comprising a 2+4 cycloaddition in the early stages, but evolving into a (degenerate) pair of [3,3] sigmatropic reactions in the latter stages.
First came Molnupiravir – now there is Paxlovid as a SARS-CoV-2 protease inhibitor. An NCI analysis of the ligand.
Authors: Rzepa Henry
Published: November 2023

Earlier this year, Molnupiravir hit the headlines as a promising antiviral drug. This is now followed by Paxlovid, which is the first small molecule to be aimed by design at the SAR-CoV-2 protein and which is reported as reducing greatly the risk of hospitalization or death when given within three days of symptoms appearing in high risk patients. The Wikipedia page (first created in 2021) will display a pretty good JSmol 3D model of this;
What is the largest angle possible at 4-coordinate carbon – 180°?
Authors: Rzepa Henry
Published: November 2023

Four-coordinate carbon normally adopts a tetrahedral shape, where the four angles at the carbon are all 109.47°. But how large can that angle get, and can it even get to be 180°? A search of the CSD (crystal structure database) reveals a spiropentane as having the largest such angle, VAJHAP with 164°[1] Because crystal structures might have artefacts such as disorder etc, it is always good to check this with a calculation;

Octafluorocubane radical anion – where does the extra electron sit?
Authors: Rzepa Henry
Published: November 2023

Derek Lowe reports the story[1] that the recently synthesized octafluorocubane can absorb one electron to form a radical anion – an electron in a cube. So I thought it would be fun to compute exactly where that electron sits! A ωB97XD/Def2-TZVPPD/SCRF=chloroform calculation (DOI: 10.14469/hpc/11090) is carried out on the neutral system (optimizing its geometry) and then the radical anion at the same geometry.
Molecule of the year 2021: Infinitene.
Authors: Rzepa Henry
Published: November 2023

The annual “molecule of the year” results for 2021 are now available … and the winner is Infinitene.[1],[2] This is a benzocirculene in the form of a figure eight loop (the infinity symbol), a shape which is also called a lemniscate [3] after the mathematical (2D) function due to Bernoulli. The most common class of molecule which exhibits this (well known) motif are hexaphyrins (hexaporphyrins;

FAIR-Enabling Services Redux
Authors: Winston Donny
Published: November 2023

I have sought to identify and enumerate core FAIR-enabling services. I attempted a five-week experiment to expand on my tentative list, but I did not complete it. The list wasn’t compelling for me. I have been brewing an updated list of core FAIR-enabling services, which I hope to be less bombastic about.
From Platforms to Microservices for FAIR Data and Analysis
Authors: Winston Donny
Published: November 2023

The “one platform1 to rule them all” is unlikely to be realized for scientific research in any domain. Rather, instead of small and numerous on-premises silos for data + code + compute, we are on track to achieve large and somewhat less numerous cloud-based silos.2 What’s the alternative?
Juan de Borgoña y los inicios del clasicismo en la catedral de Toledo
Authors: Blanco Mozo Juan Luis
Published: November 2023

La restauración de las pinturas murales de la sala capitular de la Catedral de Toledo y el análisis de dos obras que han pasado desapercibidas a la crítica artística, el sotabanco pintado de su retablo mayor y los diseños para el terno de Cisneros, permiten ofrecer un nuevo acercamiento a la significación artística de Juan de Borgoña. Su firme propósito de introducir un renovado lenguaje formal, nítidamente distanciado de las inercias goticistas, y su interés en aplicar la perspectiva a su pintura sobre la base de las arquitecturas que urdían sus composiciones, le afianzan como uno de los principales introductores del clasicismo de progenie florentina en la sede catedralicia de Toledo y su arzobispado.
Cristo esperando la crucifixión: el hallazgo de una pintura de José Maea copiando a Alonso Cano y las versiones gráficas de Álvarez de Mon
Authors: Guerola Blay Vicente , Castell Agustí María
Published: November 2023

Alonso Cano lleva a término a mitad del siglo XVII un lienzo con la representación de Cristo esperando la crucifixión influido por el naturalismo severo. No debió de pasar desapercibida esta pintura en el neoclasicismo, en tanto que dos autores como José Maea (1759-1826) y Manuel Álvarez de Mon (f. 1809) utilizaron este modelo según dos fórmulas diferentes: el primero, a través de una copia al óleo como objeto de aprendizaje y el segundo, con un dibujo y posterior grabado para optar a un premio en forma de concurso de la Academia de San Fernando.En el presente trabajo se estudian los aspectos artísticos, estéticos, iconográficos, de análisis de fuentes gráficas, así como de la historicidad propia de las obras.Con la exposición de una pintura inédita de Maea y las versiones gráficas de Álvarez de Mon, podemos analizar una convergencia hacia el estudio de una pintura barroca bajo los postulados del academicismo.
Amazonas, heroínas y diosas. La iconografía simbólica de las virreinas en las entradas triunfales novohispanas del siglo XVII
Authors: Rodríguez Moya Inmaculada
Published: November 2023

Las virreinas novohispanas estuvieron presentes en alegorías y jeroglíficos en los programas iconográficos de los arcos triunfales levantados para los virreyes en las ciudades de México y Puebla. Este texto analiza los personajes asignados por los ideólogos de los arcos, especialmente de la segunda mitad del siglo xvii, que utilizaron a menudo a figuras femeninas amantes o esposas de los héroes y dioses con los que se paragonaba al virrey. A estas mujeres y diosas de la mitología grecorromana se les atribuían una serie de virtudes acordes a lo que se esperaba de la virreina: piedad, sacrificio, armonía conyugal, fertilidad, belleza y, además, se encomiaba sus ilustres y elevados linajes.
Las virreinas se visten de fiesta. Poder y ostentación encapsulada en la Nueva España
Authors: Farré Judith
Published: November 2023

En este trabajo analizamos los usos materiales y festivos de los vestidos y tejidos asociados a la virreina en las fiestas por el nacimiento de Felipe Próspero en la ciudad de México (1658). En este relato fastuoso distinguimos cuatro espacios y circunstancias festivas: la catedral, el palacio, la máscara grave nocturna y los toros. De manera indistinta, los tejidos que tienen más presencia son el chamelote, la tela y el raso y, en todos los casos, queda constancia del esplendor de las joyas y de las puntas de hielo como complemento y adorno del traje. El vestuario de la virreina se encuadra visualmente en la performance festiva y pone de manifiesto la ostentación encapsulada propia de su agencia femenina, alineándose en los espacios cerrados que la representan y dentro del linaje nobiliario en el que participa.
La virreina mueve a la cuidad. La injerencia de las virreinas novohispanas en las procesiones. Siglo XVII
Authors: Pastor Téllez Daniela
Published: November 2023

La importancia de la presencia virreinal en las fiestas públicas en la Nueva España es más que evidente, ya que las sociedades americanas del Antiguo Régimen compartían la cultura visual de sus congéneres en la Península. El aparato ritual con el que la Corona mantenía su poder implicaba la presencia de la pareja virreinal. De esta manera, su participación estaba configurada en distintos espacios con objetivos diferenciados. Las virreinas aprovecharon su posición política y social para ganarse beneficios, entre ellos, el incremento de su poder. En las siguientes líneas me enfocaré en cuál fue el papel, el espacio y la agencia política de las virreinas novohispanas en algunas celebraciones públicas como las procesiones.
Architectural Landscape. A New Interpretation of the Sloping Ceiling of Rekhmire’s Tomb Chapel (TT 100)
Authors: Muñoz Herrera Antonio
Published: November 2023

The tomb TT 100, belonging to the vizier Rekhmire, in the Theban necropolis (Luxor, Egypt), one of the best examples of funerary architecture of the Egyptian New Kingdom, has been widely studied since the beginning of the 20th century from the iconographic, historical and archaeological points of view. However, it has an anomalous structural feature for the classic Theban tomb typology of this period: a longitudinal corridor with a sloping ceiling ending in a combination of false stela and niche for a funerary statue. The anomaly, widely noted in classical literature, has been vaguely explained and often forgotten due to the celebrated decorative program that occupies the tomb.This study aims to offer a reinterpretation of this architectural feature of the tomb based on a landscape archaeology approach. According to this methodology, the ancestral landscape of the necropolis, and the architectural and artistic features of the tomb of his relative and predecessor in the vizierate Useramun are significant elements for the interpretation of this element. The main result is Rekhmire’s clear intention to emulate and replicate Useramun’s double funerary structure, not only from the artistic point of view (already demonstrated in previous studies) but also from the spatial point of view, copying the phenomenological experience of space and landscape in the architectural development of his tomb. An example of how landscape archaeology can be useful in the study of the art of this ancient culture.
