Engagement of science process skills for teaching science concepts in early childhood
Authors: Maraisane Lintle , Jita Loyiso , Jita Thuthukile
Published: July 2024

This study aimed to explore how early childhood teachers engage science process skills for teaching science concepts in early childhood settings. Social constructivist theory was employed as the guiding framework for this study. Four Grade R teachers were purposefully selected and engaged through qualitative research methods. Data generation was informed by semi-structured interviews, classroom observations, and document analysis. Thematic data analysis was used to unpack the aim of the study. Results reveal that the low engagement of science process skills by participants was strongly influenced by their limited knowledge of content and science process skills when teaching the concepts. This finding implies that the training of early childhood teachers needs to improve and be supported with continuous development programs. This finding may inform teacher training programs and curriculum development efforts geared toward improving science education in the crucial early years of a child’s academic journey.
The effect of Philosophy for Children (P4C) activities on the development of moral perception and social rules of preschool children
Authors: Unal Ummuhan , Gunes Gokhan
Published: July 2024

The purpose of the study was to examine the effects of P4C implementations on children's perceptions of moral and social rules. The study was carried out with a total of 48 children aged five years old, 23 of them in the experimental group and 25 of them in the control group, attending a public school in the 2023–2024 academic years. A quasi-experimental design was used in the research, and the fully mixed sequential equal status design, one of the mixed research typologies, was applied. The Preschool Children's Conceptions of Moral and Social Rules Scale was applied in the quantitative dimension of the research, and observation, interviews, and anecdotal records constituted the qualitative data collection dimension. Briefly, after the implementation process, the experimental group's perception of moral and social norms improved. In the current study, a substantial difference between the children's moral rule and social rule perceptions after the P4C sessions was discovered when the experimental group's moral rule and social rule perception scale scores were analyzed before and after the implementation. A noticeable improvement in cognitive and social-emotional development was seen. It was determined that positive behaviors improved, particularly in moral situations requiring tolerance, in the experimental group. The study came to the conclusion that teaching children philosophy helps them enhance their critical thinking skills.
From IT to I-It: Digitalization, datafication, automation, and the teacher-student relationship
Authors: Mertala Pekka
Published: July 2024

This conceptual article theorises the tensioned interplay between digitalization, datafication and automation and subjectness in education by asking what intensifying datafication and automation means for teacher–student relationships and how we understand and approach education. Theoretically, the paper draws on Buber’s ideas of the dialogical I–Thou and objectified I–It as the key forms of human relationships. The core argument is that increasing datafication and automation steers the teacher–student relationship towards an objectified I–It relationship instead of the dialogical I–Thou relationship, which Buber (and others such as Biesta, another main influencer of the present paper) saw as the ideal. Literature-informed examples of various forms of educational datafication and automation are provided to support and concretise the arguments.

Yoğun bakım ünitelerine yatan hasta gruplarına uygulanan bu yeni tedavi modaliteleri hastaların son dönemlerine kadar fizyolojik parametrelerle yaşamlarına olanak sağlamaktadır. Bu durum somatik/biyolojik ölüm gerçekleşmeden önce çoğunlukla beyin ölümünün gerçekleşmesinin ön koşullarını oluşturur. Bu durumda beyin ölümü tanısının organ donasyonuna izin verecek optimal zamanda yapılması ve hasta yakınları hastanın donör olmasını kabul etmedikleri taktirde boşa çabayı engellemek ve yoğun bakım yataklarının efektif kullanımı açısından önemlidir. Bu esnada hekimlerin etik sorumluluklarını yerine getirmesi ve etik olmayan davranışların engellenmesi de öenemli bir konudur. Etiğin işlerlik kazanması için gereken nesnel koşullar ülkemizde de normlar, töreler ve kanunlardan oluşmuş ve belli bir tarihi geçmişe sahiptir. Ancak halen kanunlar nezdinde beyin ölümü açısından boşluklar bulunmaktadır.

Reflejos de lo cotidiano. Explorando la esencia del cine ecuatoriano a través de Ratas, Ratones, Rateros
Authors: Idrovo René
Published: July 2024

This essay analyzes the film Ratas, Ratones, Rateros (1999), by Ecuadorian director Sebastián Cordero, as a reflection of the social problems that affect contemporary Ecuador. Through a textual analysis of the work, it is examined how the main characters, two cousins ​​who are dedicated to theft and crime, represent the Creole liveliness, social resentment and corruption that are some of the characteristic features of Ecuadorian society. Likewise, the film is contextualized with the political and economic scenario of the country at the end of the nineties, marked by the banking crisis, dollarization and government instability. The conclusion to be reached is that Ecuadorian cinema, more than a nationalist art, functions as a mirror of daily reality; as a reflection of the identity and social problems of Ecuadorians.

Self-efficacy—the belief in using abilities for a specific purpose—is an indicator of engagement. Self-efficacy anticipates the positive results of the actions undertaken due to the knowledge and skills possessed. Within the concept of self-efficacy, we will also mention generalized self-efficacy, i.e. a person's view of himself as capable of effectively performing a wide variety of tasks and performing in a wide variety of situations. Self-efficacy has an important role in learning and developing new skills and knowledge; this applies both to patients and to the doctor or medical staff. Perceived self-efficacy helps to account for such diverse phenomena as changes in coping behavior produced by different modes of influence, the level of physiological stress reactions, self-regulation of refractory behavior, resignation and discouragement from failure. By making a correlation between self-efficacy and the patient's behavior, we can also ascertain the psychobehavioral effect this has on the patient. The quantification of the patient's self-efficacy level is directly proportional to his possibility to overcome the disease along with the involvement of other direct or indirect factors.The study was carried out on a group of 157 patients (age range 18-74 years). The questionnaire with specific questions from the internationally recognized self-efficacy scale "The General Self-Efficacy Scale (GSE)" was used. The obtained results will follow the correlation of the self-efficacy level of the patients with the paternalistic, consumerist, participative and training physician relationship.

Published: July 2024

Blockchain technology has become a disruptive force in many different industries because it provides unparalleled security, transparency, and efficiency. In the context of cooperative networks, Blockchain's decentralized architecture provides a solid basis for enhancing trust, streamlining processes, and fostering innovation. This chapter examines how Blockchain can be used with cooperative networks and how it could fundamentally alter the way entities interact and communicate. Important areas of focus include Blockchain's technological foundations, applications in collaborative environments, and case studies that highlight its impacts. By examining the challenges and opportunities presented by this convergence, we intend to provide a comprehensive understanding of how Blockchain can revolutionize cooperative ecosystems. The field of scholarly communication is undergoing a significant transition due to technological advancements. This chapter looks at how blockchain technology and collaborative networks could alter contemporary living. We examine the basic shortcomings of the existing centralized model and discuss how the core concepts of immutability, transparency, and decentralization found in Blockchain technology can assist in resolving these problems. This paper explores the relationship between collaborative networks and blockchain technology. We start by outlining the fundamental ideas behind Blockchain technology and how it has developed. The use of Blockchain is then examined in a variety of cooperative settings, with its advantages and possible drawbacks discussed. We demonstrate the real-world effects of Blockchain-enabled collaborative networks across various industries with a number of case studies.

Rice is a very popular commodity amongst Nigerian families, however the demand for rice is on the rise daily, hence an increase in rice milling activities across the country. This study is aimed at determining the impact of rice milling activities on soil quality. The samples were gotten from Auchi, Anambra and Kogi State. The samples were digested and analysed using a varian 220 atomic absorption spectrometer (AAS). Physicochemical properties showed the ph of the soil, ranging from 6.7 -9.84, temperature 29.1oC – 30oC and electrical conductivity of soil ranged from 1.3(μS/cm )- 88.2(μS/cm). The available nutrients in the soil revealed the highest values for nitrogen to be 52.2779 (mg/kg), and phosphorus to be 296.421 (mg/kg), while the highest value for potassium was 188.315 (mg/kg). Conclusively, The rice mill operations was seen to affect the soil quality parameters, due to the release of effluents on the soil, resulting in an increase in the heavy metal concentrations in the soil and decrease in the available nutrients. Accumulative geo-index revealed that Auchi is moderately polluted with cadmium and Anambra is highly polluted with zinc.

Study title: Nursing students' experiences of transfer of learning in a competency-based nursing programme in Lesotho.

Lesotho Nursing Education shifted from being content-based to competency-based. Competency-based curriculum (CBC) has been in action since 2017 in the college where the study was conducted. However, a literature search yielded no studies related to the transfer of learning since the use of CBC, and it remains unknown whether nursing students have positive or negative experiences as they transfer their learning.

This study aims to explore and describe the nursing students' experiences of transfer of learning on a competency-based nursing programme in Lesotho. The findings and recommendations from this study may assist nurse educators in enhancing students' transfer of learning.

The data for this study were gathered from the nursing students, using focus focus group interviews.

Due to their inability to self-regulate, ultrafaint dwarfs are sensitive to prescriptions in subgrid physics models that converge and regulate at higher masses. We use high-resolution cosmological simulations to compare the effect of bursty star formation histories (SFHs) on dwarf galaxy structure for two different subgrid supernova (SN) feedback models, superbubble and blastwave, in dwarf galaxies with stellar masses from 5000 < M
*/M
⊙ < 109. We find that in the “MARVEL-ous Dwarfs” suite both feedback models produce cored galaxies and reproduce observed scaling relations for luminosity, mass, and size. Our sample accurately predicts the average stellar metallicity at higher masses, however low-mass dwarfs are metal poor relative to observed galaxies in the Local Group. We show that continuous bursty star formation and the resulting stellar feedback are able to create dark matter (DM) cores in the higher dwarf galaxy mass regime, while the majority of ultrafaint and classical dwarfs retain cuspy central DM density profiles. We find that the effective core formation peaks at M

halo ≃ 5 × 10−3 for both feedback models. Both subgrid SN models yield bursty SFHs at higher masses; however, galaxies simulated with superbubble feedback reach maximum mean burstiness values at lower stellar mass fractions relative to blastwave feedback. As a result, core formation may be better predicted by stellar mass fraction than the burstiness of SFHs.

The Wang–Sheeley–Arge (WSA) model has been in use for decades and remains a popular, economical approach to modeling the solar coronal magnetic field and forecasting conditions in the inner heliosphere. Given its usefulness, it is unsurprising that a number of WSA implementations have been developed by various groups with different computational approaches. While the WSA magnetic field model has traditionally been calculated using a spherical harmonic expansion of the solar magnetic field, finite-difference potential field solutions can offer speed and/or accuracy advantages. However, the creation of new versions of WSA requires that we ensure the solutions from these new models are consistent with established versions and that we quantify for the user community to what degree and in what ways they differ. In this paper, we present side-by-side comparisons of WSA models produced using the traditional, spherical harmonic–based implementation developed by Wang, Sheeley, and Arge with WSA models produced using a recently open-sourced finite-difference code from the CORHEL modeling suite called POT3D. We present comparisons of the terminal solar wind speed and magnetic field at the outer boundaries of the models, weighing these against the variation of the WSA model in the presence of small perturbations in the computational procedure, parameters, and inputs. We also compare the footpoints of magnetic field lines traced from the outer boundaries and the locations of open field in the models. We find that the traced field-line footpoints show remarkable agreement, with the greatest differences near the magnetic neutral line and in the polar regions.
Spinal Lesions in Axial Psoriatic Disease: How Should They Be Identified and Quantified by Magnetic Resonance Imaging?
Authors: Østergaard Mikkel , Møller-Bisgaard Signe , Maksymowych Walter P.
Published: July 2024

Proper assessment of patients with psoriatic arthritis (PsA) requires assessment of all disease domains, including axial disease. Magnetic resonance imaging (MRI) is the method of choice for evaluating axial involvement in PsA. When assessing patients with PsA for spinal involvement, it is important to assess both vertebral body lesions and posterolateral lesions, such as inflammation in facet joints and costovertebral joints, and enthesitis at spinous and transverse processes. The Canada-Denmark (CanDen) assessment system for spine MRIs is the preferred method for detailed evaluation of inflammation and structural damage at various anatomical locations in the spine, and it is reproducible and sensitive to change. The Assessment of Spondyloarthritis international Society (ASAS) has recently published MRI definitions of inflammatory and structural lesions in the spine, incorporating the CanDen definitions of spinal lesions on MRI. Applying the ASAS definitions and the CanDen assessment system in clinical practice and trials is recommended. Ongoing research/studies, not least the Axial Involvement in Psoriatic Arthritis (AXIS) study, may provide a data-driven definition of axial involvement in PsA. Ongoing research is expected to further improve and validate assessment tools for axial PsA and to provide a much-needed data-driven consensus-based definition of axial involvement in PsA.

Published: July 2024

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting was held on July 13 to 15, 2023, in Dublin, Ireland, and was attended by 285 rheumatologists, dermatologists, trainees, patient research partners (PRPs), representatives of patient organizations, and industry partners. The 20th anniversary of GRAPPA was celebrated with a special presentation and archival video. Ahead of the meeting, the PRP Network met, a workshop was held by the International Dermatology Outcome Measures (IDEOM) group, and there was a workshop in which researchers discussed advancing ultrasound use to improve the management of psoriatic disease (PsD). Young-GRAPPA also held a workshop and business meeting. Multiple presentations highlighted important topics currently influencing PsD, including ensuring that patients are included in advancing research, the role of depression in PsD, the use of magnetic resonance imaging for spinal lesions, and animal models of PsD, among others. Debates focused on whether biologics should be used for mild psoriasis, whether methotrexate should remain the first-line treatment for PsD, and whether PsD is really a primary enthesitis driving joint synovitis. Here we provide an overview of the features of the GRAPPA 2023 annual meeting and introduce the manuscripts published together in this supplement as a meeting report.

Enjeux logiques et ontologiques du concept d’effectivité
Authors: Renault Emmanuel
Published: July 2024

Cet article s’efforce de distinguer les enjeux ontologiques et logiques de la théorie hégélienne de l’effectivité. Dans un premier temps, il précise en quoi la Science de la logique « coïncide » avec l’ontologie ou la « remplace ». Dans un deuxième temps, il analyse la manière dont Hegel présente la Science de la logique dans son ensemble comme une théorie logique. Il est alors possible, dans un troisième temps, de mieux comprendre la contribution de la section « Effectivité » à la théorie de la vérité de la pensée.

Didier Anzieu, un des auteurs les plus productifs de la pensée psychanalytique « à la française », a théorisé (sans dogmes et sans enfermer les cliniciens dans un système) nombre d’éléments et de concepts centraux pour la théorie de l’originaire et des premières constructions psychiques (Moi-peau, enveloppes corporelles versus enveloppes psychiques, signifiants formels, « corps de la pulsion », etc.). Ses avancées monumentales et son épistémologie, toujours articulée à la clinique, sont comme une œuvre « ouverte », porteuse d’une psychanalyse d’aujourd’hui, nous permettant de penser la clinique archaïque et les enjeux psychopathologiques les plus contemporains. De surcroît, ses travaux sur l’analyse transitionnelle, sur le cadre et la technique analytique de l’interprétation ou, ailleurs, du psychodrame et des thérapies de groupe, témoignent d’une articulation potentielle entre concepts théoriques et enjeux technico-pratiques dans la clinique. Lui rendre hommage n’est pas ici qu’un panégyrique, mais une modeste tentative d’articuler l’actualité la plus vive de son œuvre, avec les problématiques de la psychopathologie actuelle, et avec les questions paradigmatiques du lien corps/psyché pour la clinique (un cas est brièvement présenté) et pour un approfondissement métapsychologique ouvert et fécond.
Un Congrès dépacifié ? Polarisation politique, reconfigurations parlementaires et délitement de la civilité à la Chambre des représentants états-unienne
Authors: Ghemires Annis
Published: July 2024

Cet article porte sur le déclin de la civilité parlementaire à la Chambre des représentants états-unienne depuis les années 1970. Il trouve ses origines dans l’une des transformations majeures du Congrès : la centralisation de son fonctionnement, en réaction à la polarisation de la politique états-unienne. Preuve de son importance, ce déclin des sociabilités transpartisanes et de la courtoisie parlementaire s’est progressivement étendu aux entourages des élus. De plus, il n’apparaît pas sans relation avec la montée de la violence politique observée dans la société états-unienne depuis 2016. Dans ce contexte, plusieurs initiatives « pacificatrices » récentes se sont avérées relativement inefficaces à juguler un phénomène qui met de plus en plus en péril le fonctionnement ordinaire d’un Gouvernement fédéral reposant sur la diffusion de l’autorité politique et la négociation entre les pouvoirs.
Les États-Unis dans les programmes de la chaîne de télévision chinoise CGTN. Pratiques discursives et stratégies d’influence
Authors: Charon Paul
Published: July 2024

L’échec du pouvoir chinois à imposer un discours médiatique favorable autour des Jeux olympiques de 2008 a conduit le Parti communiste chinois à mettre en œuvre un programme ambitieux d’établissement de médias susceptibles de rivaliser avec CNN et Al-Jazeera dans l’espace médiatique international. CGTN, chaîne de télévision tournée vers l’étranger, est le fer de lance de cette stratégie. Si les travaux sur ce média se sont multipliés ces dernières années, les contenus informationnels et les formes discursives adoptées par CGTN demeurent peu étudiées. C’est la lacune que cet article propose de combler en se penchant sur un corpus constitué de l’ensemble des publications de l’année 2023 classées dans la rubrique « Opinion » du site internet de CGTN, auxquels ont été ajoutés les reportages de l’émission « Facts Tell », un programme qui emprunte au genre du fact-checking. Sur cette base, nous interrogeons les stratégies d’influence informationnelle de CGTN, en soulignant les principaux procédés stylistiques et rhétoriques utilisés. Nous montrons enfin comment la chaîne a su faire preuve d’innovation dans ses pratiques discursives.
Des éleveurs et éleveuses dans l’abattoir : un commun de travail aux effets systémiques
Authors: Riegel Julie , Chartier Ambre
Published: July 2024

À partir des années 1950, à l’instar du modèle agricole, le système d’abattage des animaux d’élevage s’est progressivement industrialisé, dans un processus de privatisation, de concentration et d’une rationalisation productiviste du travail. En marge de cette dynamique, de petits abattoirs de proximité ont été repris par des collectifs d’éleveurs afin d’en assurer le maintien, la gestion et la mise en service. Ces expériences méconnues sont source d’inspiration et d’essaimage aujourd’hui, au regard de l’aspiration des réseaux paysans et des consommateurs, à développer des alternatives à l’abattage industriel ainsi qu’une alimentation de proximité. À partir d’une recherche ethnologique dans un abattoir paysan des Hautes-Alpes, cet article montre comment le commun qui s’y déploie recadre par le bas le référentiel industriel de l’abattage, en modifiant les finalités et les normes de ce système dominant.
VaR calculation by binary response models
Authors: Pourkermani Kasra
Published: July 2024

The original Risk-Metrics method is underpinned by the assumption that daily asset returns are conditional Gaussian independently identically distributed (iid) random variables with a mean of zero. In this paper, a new method to calculate Value at Risk (VaR) was suggested to overcome the shortcoming of Risk-Metrics by employing binary response models to compute probability forecasts of the portfolio return by exceeding a grid of candidate quantile values. From those values, the VaR quantile value was selected. The proposed model was called BRV (Binary Response VaR method). Consistent application of BRV to the Dow Jones Industrial Average (INDEXDJX: DJI) and Dow Jones U.S. Marine Transportation Index (DJUSMT) time series proved that it was more accurate than the Risk-Metric system. This method not only worked similar to quantile regression but had the advantage that conventional maximum likelihood methods could be used for parameter estimation and inference. The BRV method was the best performing method for computing the daily VaR at both the 95% and 99% confidence levels over the period 02/01/06–31/12/08. The BRV and the QR (quantile regression) methods performed similarly, but the BRV method had the practical advantage that conventional maximum likelihood (ML) technique could be used for parameter estimation and robust inference.
Hamiltonian conserved Crank-Nicolson schemes for a semi-linear wave equation based on the exponential scalar auxiliary variables approach
Authors: Li Huanhuan , Kang Lei , Li Meng , Luo Xianbing , Xiang Shuwen
Published: July 2024

The keys to constructing numerical schemes for nonlinear partial differential equations are accuracy, handling of the nonlinear terms, and physical properties (energy dissipation or conservation). In this paper, we employ the exponential scalar auxiliary variable (E-SAV) method to solve a semi-linear wave equation. By defining two different variables and combining the Crank−Nicolson scheme, two semi-discrete schemes are proposed, both of which are second-order and maintain Hamiltonian conservation. Two numerical experiments are presented to verify the reliability of the theory.
Optimizing SNARK networks via double metric dimension

Doubly resolving sets (DRSs) provide a promising approach for source detection. They consist of minimal subsets of nodes with the smallest cardinality, referred to as the double metric dimension (DMD), that can uniquely identify the location of any other node within the network. Utilizing DRSs can improve the accuracy and efficiency of the identification of the origin of a diffusion process. This ability is crucial for early intervention and control in scenarios such as epidemic outbreaks, misinformation spreading in social media, and fault detection in communication networks. In this study, we computed the DMD of flower snarks $ J_{m} $ and quasi-flower snarks $ G_{m} $ by describing their minimal doubly resolving sets (MDRSs). We deduce that the DMD for the flower snarks $ J_{m} $ is finite and depends on the network's order, and the DMD for the quasi-flower snarks $ G_{m} $ is finite and independent of the network's order. Furthermore, our findings offer valuable insights into the structural features of complex networks. This knowledge can offer direction for future studies in network theory and its practical implementations.
Modeling Norm-Governed Communities with Conditional Games: Sociological Game-Determination and Economic Equilibria
Authors: Ross Don , Stirling Wynn C. , Tummolini Luca
Published: July 2024

Most social scientists agree that informal norms constrain available equilibria in most human interactions. However, they do not agree on how to model them: economists often make them derivative of individual preferences, while a broader tradition in social theory understands them as exogenous social facts. Non-cooperative game theory more naturally accommodates the economists’ approach. However, attention is increasingly attracted to recent work by economists who appreciate that the broader understanding may be important for full empirical adequacy. We focus on how game theorists might track this emerging shift. Extending Stirling’s previously developed Conditional Game Theory, we model macrostructural processes of norm evolution through social influence diffusion in a way that relies on no exotic solution concepts, which in turn allows norms as social facts and norms as expressions of preferences to be modeled as evaluable complements, by analogy to the complementarity of cooperative and non-cooperative game solutions under the Nash program. The result can be understood as a way of specifying mutual constraints between economic models in which normative attitudes are exogenous, and sociological models that represent such attitudes as endogenous under power relationships and ontologies of social roles.
Deux moments dans les relations entre l’économie et l’anthropologie : histoire et enjeux méthodologiques
Authors: Dutraive Véronique
Published: July 2024

Cet article porte sur les liens entre l’économie et l’anthropologie. Le texte se fonde sur deux moments de l’histoire pour caractériser les relations entre ces deux disciplines et leurs frontières. Le premier correspond à l’émergence de l’anthropologie économique et les controverses entre les formalistes et les substantivistes, dans les années 1940. L’échange entre l’anthropologue Melville Herskovits et l’économiste Frank Knight témoigne de l’intérêt de l’anthropologie pour dialoguer avec l’analyse économique, un intérêt non réciproque de la part d’une économie fermée sur ses propres concepts. La seconde période discute de la contribution de l’anthropologie, portée principalement par Joseph Henrich, au programme de recherche de l’économie comportementale, et propose la mise en perspective de l’anthropologie critique de David Graeber et de l’approche comportementale de Samuel Bowles et Herbert Gintis.
Management and Microeconomics: A Historical Comparison between the British and the French Traditions
Authors: Arena Lise , Arena Richard
Published: July 2024

This article seeks to analyse the circumstances and the nature of the emergence of management research in economic analysis in the 1950s in Britain and France. The goal is also to look at the more recent shifts in the boundaries between these two social sciences; and to understand their analytical and methodological significance by taking into account the different historical and cultural contexts within which they were embedded.
Analyser l’économie en physicien : introduction à la pensée économique de Marion King Hubbert
Authors: Joulin Ambroise
Published: July 2024

Marion King Hubbert (1903-1989) est un géophysicien connu pour ses travaux au sujet de l’épuisement des ressources pétrolières (théorie dite du « pic pétrolier »). Mais Hubbert est également un théoricien et militant politique engagé dans le Mouvement Technocratique, un mouvement politique principalement actif dans les années 1930 aux États-Unis. Ce mouvement est caractérisé par une analyse de l’économie en termes physiques et par la revendication d’une planification intégrale de l’économie sous le contrôle des ingénieurs. Hubbert donnera la formulation la plus systématique de la pensée de ce mouvement dans Technocracy Study Course (Hubbert, [1934] 2005), un ouvrage destiné à la formation scientifique et politique des militants de l’organisation dont il est le co-fondateur. Cet article analyse la manière dont cet ouvrage questionne la frontière entre économie et sciences de la nature en distinguant d’un côté les fait économiques qui constituent une transformation d’énergie et de ressources et sont donc soumis aux lois physiques ; de l’autre les phénomènes monétaires, régis par des conventions humaines. Nous commentons la manière dont Hubbert construit une théorie critique de l’économie de marché en partant d’un usage non-métaphorique de la physique et montrons comment son raisonnement aboutit à l’idée d’une planification économique en termes énergétiques. Ces éléments font d’Hubbert un auteur pertinent pour l’étude de l’histoire des approches bio-physiques en économie.
