Isolated, individualised, and immobilised: information behaviour in the context of academic casualisation
Authors: Willson Rebekah , Stewart-Robertson Owen , Julien Heidi , Given Lisa M.
Published: June 2024

Introduction. Universities rely increasingly on contract academic staff for teaching and research activities; yet, working in precarious conditions, these staff face significant challenges in finding relevant workplace information, in engaging with colleagues, and in building their careers. This study examines contract academic staff perceptions of precarity and workplace marginalisation, focusing on the implications of situational and environmental influences on their information practices.
Method. In-depth, semi-structured interviews with 34 contract academic staff, working in various disciplines across Canadian universities, were conducted to examine their information practices.
Analysis. Interview data were analysed using reflexive thematic analysis, drawing on everyday life information seeking and information marginalisation theories.
Results. Results of the study show that 1) contract academic staff conduct their work within isolated information environments; 2) this isolation leads these staff to develop highly individualised information practices; and 3) the information activities of contract academic staff are often immobilised, due to the precarious contexts that shape their work and personal lives.
Conclusion. Precarious employment and information marginalisation are deeply entwined for contract academic staff. This results in frustration, disappointment, and uncertainty with their work and personal circumstances. Institutional challenges can seem intractable, particularly where task-related information provision (when available) cannot address systemic concerns.

Published: June 2024

Introduction. Obsessive-compulsive Disorder (OCD) is a severe chronic mental health issue that significantly impacts people’s everyday lives. This study aims to reveal the contextual information needs of the people living with OCD during life transitions and how these needs dynamically evolve across various transitional stages.
Method. The study collected 1,500 posts from an OCD online forum of a well-known Chinese social media platform, Douban. A subsequent content analysis was performed on 324 selected valid posts.
Analysis. Guiding by the information behaviour theory of transitions, two rounds of open-coding analyses were conducted on the posts.
Results. Preliminary findings indicate that people with OCD have various types of contextual information needs during different transitional stages, namely understanding, negotiating, and resolving, suggested by the existing theory.
Conclusion. Information needs are context-specific, complex and continuously changing during life transitions of people with OCD. Our conclusion can provide theoretical insights for future research exploring the dynamic information needs during the mental health transitions. Additionally, it serves as a preliminary conceptual framework for various stakeholders to offer informational support to people with OCD.

Published: June 2024

Introduction. Governance process optimisation is critical to achieve the goal of improving public services efficiency. Public data service  is crucial starting point for realising this goal. However, practical challenges persist in public data service, including unclear processes and insufficient identification of public data service citizens’ information needs.
Method & Analysis. We employed an inductive methodology to analyse the public data service users’ information needs and annual distribution among information needs. Based on a data-driven approach, we mapped these information needs sub-categories into four main procedures in public data service. This paper further identified the hierarchy of information needs based on public data processing levels. We utilised Sankey diagram to effectively illustrate cross-analysis result between topics and information needs’ subcategories.
Results. The typical levels of public data service users’ information needs include informing, utilisation, problem-solving, social life service, and society governance. Furthermore, our study reveals the data flow among sub-categories of public data service information needs follows the logic of Datafication- Government to Government-Government to citizens- Data to Optimiation.
Conclusion. Government departments should ensure public data quality and facilitate efficient data circulation processes. We recommend understanding relationships between public data resources and services derived from them through a problem-solving lens. Our findings will serve as a reference tool for analysing information needs of public data service users in other countries.
¿Sueñan las Inteligencias Artificiales (IA) con cerebros positrónicos? Ciencia Ficción y Posthumanismo
Authors:   Universidad Indoaméricana, Endara Fernando David
Published: June 2024

La Ciencia Ficción se centra en la especulación científica y tecnológica, el multiverso, y la sociedad. En este artículo se analizan dos obras paradigmáticas del género: “Yo Robot” de Isaac Asimov y “Sueñan los Androides con ovejas eléctricas” de Philip K. Dick. De las 2 obras se revisan tanto los textos originales como sus adaptaciones cinematográficas, para verificar el impacto de estas obras en el desarrollo científico de las IA. Por un lado, las leyes de la robótica de Asimov se insertan en los debates contemporáneos sobre las regulaciones éticas y legales de las IA; mientras las ideas del ciborg/replicante de Dick se engranan a las discusiones actuales sobre el posthumanismo y la sostenibilidad.
El surgimiento de la etnografía multiespecie
Authors:   University of Oxford, Kirksey S. Eben , Helmreich Stefan ,   Massachusetts Institute of Technology (MIT)
Published: June 2024

Los antropólogos se han dedicado, al menos desde Franz Boas, a investigar las relaciones entre la naturaleza y la cultura. En los albores del siglo XXI, este perdurable interés se ha visto influido por algunos giros nuevos. Una cohorte emergente de "etnógrafos multiespecie" empezó a hacer hincapié en la subjetividad y la agencia de los organismos cuyas vidas están intricadas con las de los humanos. La etnografía multiespecie surgió en la intersección de tres ejes interdisciplinarios de investigación: los estudios medioambientales, los estudios sobre ciencia y ciencia y la tecnología (CTS) y los estudios sobre animales. Partiendo de temas etnobiológicos clásicos, plantas útiles y animales carismáticos, los etnógrafos multiespecie también incorporaron organismos poco estudiados –como insectos, hongos y microbios– a los debates antropológicos. Los antropólogos se reunieron en el Salón Multiespecie, una exposición de arte, donde se exploraron los límites de una interdisciplina emergente en medio de una colección de organismos vivos, artefactos de las ciencias biológicas, y sorprendentes intervenciones biopolíticas sorprendentes.
Hacia un nuevo régimen del conocimiento en el Antropoceno. La contribución de la antropología
Authors:   Universidad de Oslo, Hylland Eriksen Thomas
Published: June 2024

El mundo está sobrecalentado, la civilización global se ha arrinconado y negocia un incómodo doble dilema entre los imperativos del crecimiento y la urgente necesidad de soluciones sostenibles. Hoy en día existe un amplio consenso sobre la necesidad urgente de tomar en serio estos retos en la investigación, la movilización política y la elaboración de políticas. La cuestión es qué tipo de conocimiento se necesita para dar los pasos adecuados. La respuesta corta es: Muchos tipos de conocimiento. Una respuesta más larga comienza con una pregunta complementaria: ¿Qué conocimientos? Utilizando el concepto y la metáfora del sobrecalentamiento para explicar el estancamiento contemporáneo, esta contribución muestra la importancia de la interdisciplinariedad y se pregunta hasta qué punto los conocimientos producidos en antropología pueden contribuir al tipo de esclarecimiento que se necesita. ¿Debemos aprender de los errores y aciertos del pasado, buscar los conocimientos necesarios en las pequeñas sociedades restantes o, por el contrario, insistir en que la modernidad tiene que resolver sus contradicciones por sus propios medios, ya sea con algún tipo de gobierno global o con soluciones tecnológicas?
Nullo modo separari valet. La superación del sujeto moderno desde la antropología de Hildegarda de Bingen
Authors:   Universidad Rey Juan Carlos, Escobar Torres Miguel
Published: June 2024

En el presente artículo defiendo la necesidad de volver sobre la antropología hildegardiana, que concibe al hombre como crisol de la creación y tan unido a la tierra que no puede separarse de ella, pues nos proporciona las herramientas gnoseológicas y metafísicas que permiten diagnosticar al sujeto moderno y superarlo, alumbrando de este modo una forma distinta de dominio. La relación entre el hombre y la naturaleza debe estar marcada no por un dominio arbitrario y limitado sólo por el puro poder, como se desprende del sujeto ausente de la modernidad, sino por una acción humana que, nutriendo la tierra de la que el hombre mismo está hecho, garantice la armonía y el equilibrio de un ecosistema humanizado.

Distribution of nutrients and dissolved organic matter in a eutrophic equatorial estuary: the Johor River and the East Johor Strait
Authors: Cheong Amanda Y. L. , Annammala Kogila Vani , Yong Ee Ling , Zhou Yongli , Nichols Robert S. , Martin Patrick
Published: June 2024

Abstract. Estuaries have strong physicochemical gradients that lead to complex variability and often high rates of biogeochemical processes, and they are also often impacted by humans. Yet, our understanding of estuarine biogeochemistry remains skewed towards temperate latitudes. We examined seasonal and spatial variability in dissolved organic matter (DOM) and nutrients along a partly eutrophic, agricultural–urban estuary system in Southeast Asia: the Johor River and the East Johor Strait. Dissolved organic carbon (DOC) and coloured DOM (CDOM) showed non-conservative mixing, indicating significant DOM inputs along the estuary. The CDOM spectral slopes and CDOM : DOC ratios suggest that terrigenous, soil-derived DOM dominates along the Johor River, while phytoplankton production and microbial recycling are important DOM sources in the Johor Strait. CDOM properties were not unambiguous source indicators in the eutrophic Johor Strait, which is likely due to heterotrophic CDOM production. Nitrate concentrations showed conservative mixing, while nitrite concentrations peaked at intermediate salinities of 10–25. Ammonium concentrations decreased with salinity in the Johor River but increased up to 50 µmol L−1 in the Johor Strait, often dominating the dissolved inorganic nitrogen (DIN) pool. Phosphate concentrations were low (<0.5 µmol L−1) throughout the Johor River but increased in the Johor Strait, where DIN : phosphate ratios were typically ≥ 16 : 1. This suggests that the Johor Strait may experience phosphorus limitation and that internal recycling is likely important for maintaining high nutrient concentrations in the Johor Strait. Overall, our results indicate that the Johor River and Johor Strait are clearly not part of the same estuarine mixing continuum and that nutrient recycling processes must be quantified to understand nutrient dynamics in the Johor Strait. Moreover, our results highlight the need for better techniques for DOM source tracing in eutrophic estuaries.

Abstract. Supraglacial lake drainage through fractures delivers vast amounts of water to the ice sheet base on timescales of hours. This study is concerned with the mechanisms of supraglacial lake drainage and how a particular area of Nioghalvfjerdsbræ with a lake of a volume up to 1.23 · 108 m3. We found extensive fracture fields being formed and vertical displacement across the fracture faces in some instances. The fractures are accommodated with triangular gullies, in the order of 10’s m’s, into which water is flowing still weeks after the main lake drainage, but also instances in which the water level rises over the surface end of summer. These gullies are sometimes reactivated in subsequent years and their size at the surface remains unchanged over some years, which is in agreement with viscoelastic modelling. Using ice-penetrating radar, we find englacial, three-dimensional features originating from the drainage, changing over years but remaining detectable even years after their formation. The drained water forms a blister underneath the lake, which is released over several weeks. In this area, no lakes existed before an increase in atmospheric temperatures in the mid-1990s as we demonstrate using reanalysis data. It is transformed from lake-free to frequent, abrupt drainage delivering massive amounts of lubricant and freshwater at the seaward margin.

Abstract. The advancement of analytical techniques, such as comprehensive two-dimensional gas chromatography coupled with mass spectrometry (GC×GC-MS), enables the efficient separation of complex organic matrix. Developing innovative methods for data processing and analysis is crucial to unlock the full potential of GC×GC-MS in understanding intricate chemical mixtures. In this study, we proposed an innovative method for the semi-automated identification and quantification of complex organic mixtures using GC×GC-MS. The method was formulated based on self-constructed mass spectrum patterns and the traversal algorithms and was applied to organic vapor and aerosol samples collected from tailpipe emissions of heavy-duty diesel vehicles and the ambient atmosphere. Thousands of compounds were filtered, speciated, and clustered into 26 categories, including aliphatic and cyclic hydrocarbons, aromatic hydrocarbons, aliphatic oxygenated species, phenols and alkyl-phenols, and heteroatom containing species. The identified species accounted for over 80 % of all the eluted chromatographic peaks at the molecular level. A comprehensive analysis of quantification uncertainty was undertaken. Using representative compounds, quantification uncertainties were found to be less than 37.67 %, 22.54 %, and 12.74 % for alkanes, polycyclic aromatic hydrocarbons (PAHs), and alkyl-substituted benzenes, respectively, across the GC×GC space, excluding the first and the last time intervals. From source apportionment perspective, adamantane was clearly isolated as a potential tracer for heavy-duty diesel vehicles (HDDVs) emission. The systematic distribution of N-containing compounds in oxidized and reduced valences was discussed and many of them served as critical tracers for secondary nitrate formation processes. The results highlighted the benefits of developing self-constructed model for the enhanced peak identification, automated cluster analysis, robust uncertainty estimation, and source apportionment and achieving the full potential of GC×GC-MS in atmospheric chemistry.

Published: June 2024

Abstract. Atmospheric emissions from anthropogenic hotspots, i.e., cities, power plants and industrial facilities, can be determined from remote sensing images obtained from airborne and space-based imaging spectrometers. In this paper, we present a Python library for data-driven emission quantification (ddeq) that implements various computationally light methods such as the Gaussian plume inversion, cross-sectional flux method, integrated mass enhancement method and divergence method. The library provides a shared interface for data input and output and tools for pre- and post-processing of data. The shared interface makes it possible to easily compare and benchmark the different methods. The paper describes the theoretical basis of the different emission quantification methods and their implementation in the ddeq library. The application of the methods is demonstrated using Jupyter notebooks included in the library, for example, for NO2 images from the Sentinel-5P/TROPOMI satellite and for synthetic CO2 and NO2 images from the Copernicus CO2 Monitoring (CO2M) satellite constellation. The library can be easily extended for new datasets and methods, providing a powerful community tool for users and developers interested in emission monitoring using remote sensing images.
Observed change and the extent of coherence in the Gulf Stream system
Authors: Asbjørnsen Helene , Eldevik Tor , Skrefsrud Johanne , Johnson Helen L. , Sanchez-Franks Alejandra
Published: June 2024

Abstract. By transporting warm and salty water poleward, the Gulf Stream system maintains a mild climate in northwestern Europe while also facilitating the dense water formation that feeds the deep ocean. The sensitivity of North Atlantic circulation to future greenhouse gas emissions seen in climate models has prompted an increasing effort to monitor the various ocean circulation components in recent decades. Here, we synthesize available ocean transport measurements from several observational programs in the North Atlantic and Nordic Seas, as well as an ocean state estimate (ECCOv4-r4), for an enhanced understanding of the Gulf Stream and its poleward extensions as an interconnected circulation system. We see limited coherent variability between the records on interannual timescales, highlighting the local oceanic response to atmospheric circulation patterns and variable recirculation timescales within the gyres. On decadal timescales, we find a weakening subtropical circulation between the mid-2000s and mid-2010s, while the inflow and circulation in the Nordic Seas remained stable. Differing decadal trends in the subtropics, subpolar North Atlantic, and Nordic Seas warrant caution in using observational records at a single latitude to infer large-scale circulation change.
Anomalous North Pacific subtropical mode water volume and density decrease in a recent stable Kuroshio Extension period from Argo observations
Authors: Sheng Jing , Liu Cong , Gu Yanzhen , Li Peiliang , Zhai Fangguo , Zhou Ning
Published: June 2024

Abstract. North Pacific subtropical mode water (NPSTMW) is formed as a low-stratification water mass in the wintertime mixed layer south of the Kuroshio Extension (KE). In a recent period of 2018–2021, the KE jet was in a persistent stable dynamic state. But based on analysis of Argo observation, the mean volume of NPSTMW in the ventilation region dropped anomalously by ∼ 21 % during 2018–2021 relative to 2012–2015, when the KE jet was likewise stable. Moreover, the NPSTMW volume in a denser density range (approximately σθ>25.2 kg m−3) has started to decrease since 2018. The decreases in the NPSTMW subduction and formation rate are associated with anomalously shallow wintertime mixed-layer depth (MLD) and weak heat loss in the NPSTMW formation region. The decrease in air–sea heat exchange acts to weaken the vertical mixing and decrease the MLD, resulting in the weakening of subduction. The interannual variations in the air–sea heat exchange and wintertime MLD reflect the variability in the overlying atmosphere, which is correlated with a Pacific Decadal Oscillation (PDO) shift in 2018–2021. When the PDO shifted from its positive phase to a negative phase in the analysis period, the effects of local wind stress anomalies seemed to play an evident role in driving the variability in NPSTMW on interannual timescales. The MLD and heat loss change during the cold season in 2018–2021 were strongly coupled with the poleward shift of the westerlies – which cause weaker wintertime wind and easterly wind anomalies over the NPSTMW formation region. The declines in heat loss and southward Ekman transport, owing to the wind stress anomalies, further prohibit upper-ocean convection and mixed-layer deepening and cooling. Additionally, the insufficient development of wintertime MLD in 2018–2021 may also be associated with the significantly intensified preconditioning of near-surface stratification (< 150 m depth) due to the persistent near-surface warming and the weak vertical entrainment process in winter.
Past and future of the Arctic sea ice in High-Resolution Model Intercomparison Project (HighResMIP) climate models
Authors: Selivanova Julia , Iovino Doroteaciro , Cocetta Francesco
Published: June 2024

Abstract. We examine the past and projected changes in Arctic sea ice properties in six climate models participating in the High-Resolution Model Intercomparison Project (HighResMIP) in the Coupled Model Intercomparison Project Phase 6 (CMIP6). Within HighResMIP, each of the experiments is run using a reference resolution configuration (consistent with typical CMIP6 runs) and using higher-resolution configurations. The role of horizontal grid resolution in both the atmosphere model component and the ocean model component in reproducing past and future changes in the Arctic sea ice cover is analysed. Model outputs from the coupled historical (hist-1950) and future (highres-future) runs are used to describe the multi-model, multi-resolution representation of the Arctic sea ice and to evaluate the systematic differences (if any) that resolution enhancement causes. Our results indicate that there is not a strong relationship between the representation of sea ice cover and the ocean/atmosphere grids; the impact of horizontal resolution depends rather on the sea ice characteristic examined and the model used. However, the refinement of the ocean grid has a more prominent effect compared to the refinement of the atmospheric one, with eddy-permitting ocean configurations generally providing more realistic representations of sea ice area and sea ice edges. All models project substantial sea ice shrinking: the Arctic loses nearly 95 % of sea ice volume from 1950 to 2050. The model selection based on historical performance potentially improves the accuracy of the model projections and predicts that the Arctic will turn ice-free as early as 2047. Along with the overall sea ice loss, changes in the spatial structure of the total sea ice and its partition in ice classes are noticed: the marginal ice zone (MIZ) will dominate the ice cover by 2050, suggesting a shift to a new sea ice regime much closer to the current Antarctic sea ice conditions. The MIZ-dominated Arctic might drive development and modification of model physics and parameterizations in the new generation of general circulation models (GCMs).

RESUMO: O presente trabalho tem o desejo de ampliar o debate sobre a importância da educação para as relações étnico-raciais na educação infantil e oferecer disparadores que possibilitem a construção de estratégias para o enfrentamento do racismo no cotidiano escolar. Uma reflexão teórico-prática que parte de nossas experiências educativas, enquanto professoras e pesquisadoras negras que estudam infâncias e negritude, e do aporte teórico de epistemologias negras necessárias para reconstruir o processo educativo com a Lei 10.639/03. Afirmamos, a partir dos Estudos do Cotidiano, o espaço escolar como ambiente importante na construção de subjetividades e trazemos possíveis caminhos para criação de práticas antirracistas e enegrecidas. Portanto, com inspiração nos valores civilizatórios afro-brasileiros arriscamos palavras, sentidos e apostas educativas em desenho de uma gira de pensamentos infantis para denegrir a educação e suas relações.

Published: June 2024

Resumo: Este artigo problematiza a importância de uma literatura infantil que empodere as crianças negras, valorize as diferenças étnico-raciais, suas culturas locais, regionais e de matriz africana. Partimos de uma revisão de literatura com base nos estudos decoloniais e, posteriormente, tecemos a análise de quatro contos adaptados e ambientados no Brasil e que trazem personagens negros como atores principais: Afra e os três Lobos-Guarás (2013), Chapeuzinho Vermelho e o Boto-cor-de-rosa (2020), Cinderela e Chico Rei (2015) e Rapunzel e o Quibungo (2012). Ao analisar essas obras percebemos a valorização dos personagens negros da cultura regional e local e da fauna e flora brasileira. O estudo problematiza que urge resgatar no âmbito escolar uma literatura para crianças que descolonize a infância, tematize as diferenças étnico-raciais e que sua produção se distancie do autoritarismo pedagógico, das lições moralizantes e visões adultocêntricas que muitas vezes buscam domesticar e governar a infância.

Comparative Antimicrobial Activity and Bioactive Constituents of Oils from Rhizomes of Zingiber Officinale Roscoe Obtained by Different Extraction Methods
Authors: B. A. Feyisara , O. O. Olufunmiso
Published: June 2024

Ginger, known for its rich array of bioactive compounds, holds significant therapeutic potential due to its diverse medicinal properties. This study investigated the antimicrobial activity and bioactive principles present in ginger rhizome oils obtained using three different extraction methods viz: liquid-liquid extraction, cold maceration, and soxhlet extraction. The oils’ bioactive principles were identified by Gas Chromatography Mass Spectrometry (GC-MS) while their antimicrobial activity was determined by agar well diffusion technique. The GC-MS analysis revealed the presence of thirty compounds in each of the oils from liquid-liquid extraction and cold maceration, and fifty four compounds in the soxhlet-extracted oil. The most predominant compound in both liquid-liquid (31.13%) and cold maceration (16.99%) oils was oleic acid whereas the Soxhlet-extracted oil contained predominantly linoleic acid methyl ester (9.27%). Some bioactive compounds identified in these oils include δ-elemene, isoborneol, α-Bisabolol oxide, stearic acid, undecanone, palmitic acid, α-copaene, zingiberene, aromadendrene, farnesol, 2-methylhexane and farnesene which possess antioxidant, antibacterial, antifungal, antiviral, anti-inflammatory, anti-ulcer, anti-cancer, hypolipidemic, mosquito repellant, antimicrobial, and antidiabetic activities. Additionally, the oils exhibited promising antimicrobial potential against the test organisms with Staphylococcus aureus showing the least susceptibility to all the samples. Staphylococcus aureus and Candida albicans were completely resistant to the oil obtained by Soxhlet extraction at all tested concentrations. Meanwhile, Klebsiella pneumoniae (20 mm), Proteus vulgaris (18 mm), and Pseudomonas aeruginosa (17 mm), were most susceptible to the oil obtained by liquid-liquid extraction, cold maceration and soxhlet extraction, respectively. The study highlighted the significance of extraction methods on the chemical composition and antimicrobial activity of ginger rhizome oils, underscoring the importance of choosing appropriate extraction techniques to optimize the oils' therapeutic properties for specific medicinal applications.

Fournier's gangrene is a life-threatening condition characterized by rapidly progressive necrotizing fasciitis, often leading to sepsis and multiple organ failure. While historically associated with males, the condition can affect both genders, with varying degrees of severity. This case report explores the complex management of a 59-year-old male patient with a history of alcohol abuse, diabetes, cirrhosis, and a long-term smoking habit, who presented with Fournier's gangrene. The patient's critical condition and complex medical history presented significant challenges for healthcare providers, particularly nurses, who played a pivotal role in his care. These cases occur rarely in practice and require specific care and compliance with surgical nursing techniques per protocol. This case report not only sheds light on the growing incidence of Fournier's gangrene among both genders but also underscores the indispensable role of nurses in the multidisciplinary care of patients with this challenging condition. Comprehensive nursing care, patient education, and meticulous attention to detail are essential in improving patient outcomes and reducing mortality rates associated with Fournier's gangrene.
Transition in the Hypersonic Boundary Layer
Authors: Lee Cunbiao
Published: June 2024

The transition in the hypersonic boundary layer represents a pivotal area of
interest within the fluid mechanics community. This talk provides a review of
the recent advancements in hypersonic boundary-layer transition studies,
encompassing research facilities and experimental methodologies. It
introduces the hypersonic quiet wind tunnel as an essential tool for acquiring
near-space real flight data. Techniques for near-wall measurement, including
temperature-sensitive paint, near-wall particle image velocimetry, infrared
thermography, and Rayleigh-scattering visualization, are explored. The talk
addresses critical issues in hypersonic boundary layer transitions, focusing on
the instability and nonlinear interaction among various instability modes. It
proposes the phase-locked mechanism of these instability modes and
introduces a novel principle of aerodynamic heating in hypersonic flows.
Additionally, it thoroughly discusses the structural formation of boundary
layers over flat plates, sharp cones, flared cones, and delta wings.

I LAGH (ormoni della crescita long-acting): cosa sono e a chi proporli?
Authors: Rodaro Chiara , Tornese Gianluca
Published: June 2024

Children with growth hormone deficiency are currently treated with daily injections of recombinant growth hormone. The burden due to 365 injections per year and cold chain storage causes a poor medication adherence. Long-acting GH was developed to decrease injection frequency and to therefore promote a better therapeutic compliance. In this paper, we discuss about which long-acting drugs are currently on the market, their mechanism of action and which groups of patients may benefit from them.

Speculative Cannibalism: Derrida and Viveiros de Castro on Eating-the-Other
Authors: Campos-Salvaterra Valeria
Published: June 2024

“Speculative cannibalism” names here some kind of transcendental logic that only works through figuration, in the specific form of an analogical matrix. This article tracks these configurations in the philosophical works of Jacques Derrida and in the anthropological foundations of Eduardo Viveiros de Castro. This article states that as transcendental, this analogical matrix is the condition of possibility of the meaning of alterity and difference—but as analogical works as a transcategorial function that is neither beyond nor before experience, only irreducible to a given explanatory category of judgment or being. This function is figurative, that is, constitutes meaning by an operation of comparison in Viveiros de Castro’s nomenclature, and of supplementation, in Derrida’s terminology. In both cases this function posits difference or equivocation as the main operator. Finally, this article argues that even though they are very similar speculative proposals, analogy works a bit differently for deconstruction and for post-structural anthropology: for the first, analogy is based on a supplementary logic that is only taken to be a formal operation, while for the former, analogy it is treated not only as a formal operation, but also as fixed within the material categories of Amerindian thought.
Philosophical Foundations of the Critical Theory from the Americas on the Social Philosophies of Bolívar Echeverría and Adolfo Sánchez Vázquez
Authors: Gandler Stefan
Published: June 2024

This article wants to expose some central contributions for a critical theory from the Americas, made first of all from the Ecuadorian-Mexican philosopher Bolívar Echeverría and also by the Spanish-Mexican philosopher Adolfo Sánchez Vázquez, bringing them to an imaginary discussion with Alfred Schmidt, Karl Marx, and some concepts of the original critical theory from the now one-hundred-year-old Frankfurt school. The relationship between use value and value, the critique of some Eurocentric “philosophical” ideas inside nonmainstream theories are some of the departing points. A critical theory from the Americas could be a first step toward the necessary philosophical contributions for a postcapitalist society that may exist without the Today’s self-destructive impulse. It helps not only to understand the world outside the so-called First World in a more exact way, but it helps also to understand the centers of global power in a better way, as their self-consciousness is now probably on the lowest level ever.
Communities and Identities: Gendered Reconstructionist Ideas for Africa
Authors: Akiode Olajumoke
Published: June 2024

The task of reconstructing African identity and community is made particularly difficult by, among other things, the fact that African countries are not homogeneous and the fluidity, relationality, and contextuality of the concept of identity. In light of this complexity, the challenge of such a reconstruction is engaging in an in-depth critical assessment of African cultural values, beliefs, goals, and aspirations, restoring what needs to be restored, jettisoning what is irrelevant, and adding what is truly beneficial from other communities. As a response to this challenge, this article argues that, to be complete and viable, the process of reconstruction must be gendered. It illustrates the process of gendered reconstruction by underscoring what that entails in the areas of women’s lived experience, the home, the workplace/marketplace, and scholarship.
