Pengaruh Konflik Kerja dan Konfil Keluarga terhadap Kinerja Karyawan
Authors: Adetya Sandra
Published: January 2025

Work-family conflict is a common issue faced by employees across various sectors, which can significantly impact their performance. This conflict arises when the demands of work and family collide, creating tension and stress that affect psychological well-being and productivity. Therefore, it is crucial to understand the relationship between work-family conflict and its effects on employee performance, as well as explore ways to manage and mitigate this conflict. This study aims to analyze the influence of work conflict and family conflict on employee performance by referring to relevant theories and previous research, and to provide recommendations for organizations in managing this conflict. This research utilizes a literature review method by examining relevant national and international journals and previous studies from the past five years. Data was collected through content analysis of articles discussing work-family conflict and its impact on performance, as well as policies to reduce its negative effects. The findings show that work-family conflict significantly affects employee performance by increasing stress, fatigue, and reducing productivity. Theories such as Role Theory and Conservation of Resources Theory explain how conflicts between work and family roles deplete individual resources, leading to decreased performance. Additionally, policies supporting work-life balance, such as flexible working hours, social support, and wellness programs, have been proven to effectively mitigate the negative impact of this conflict.

Takwa: Landasan Spiritual dalam Menghadapi Ketimpangan Ekonomi dan Mewujudkan Keadilan Sosial
Authors: Susanto Dedi , Abubakar Achmad , Galib Muhammad
Published: January 2025

This research examines the role of piety in promoting social justice, with a particular focus on the growing economic inequality in society. Piety, defined as moral and spiritual awareness of responsibility to God, is expected to motivate individuals and communities to act justly and contribute to the improvement of social welfare. Using a descriptive qualitative approach, this study integrates the concept of piety with the theory of social justice proposed by John Rawls, which emphasizes the importance of fair and equitable distribution of resources. The results show that piety has great potential as a driver of inclusive and equitable social policies, encouraging individuals to care more about others. However, challenges in its implementation, including ambiguity in understanding and misuse of piety values to justify injustice, remain to be overcome for piety to truly become a tool for change. The findings are expected to make a significant contribution to the development of more just and equitable public policies, and inspire concrete actions in a more prosperous society.
A pre-rule for the sequential probability ratio test in a between-item grid multidimensional computerized classification test
Authors: Hu Po-Hsien , Shih Ching-Lin , Chen Cheng-Te
Published: January 2025

The measurement efficiency of a grid multidimensional computerized classification test (grid MCCT), which makes a classification decision per dimension, can be improved by taking the correlations between the dimensions into account in the termination criterion. The higher the correlations, the better the improvement in measurement efficiency. However, a termination criterion utilizing inter-dimensional information (i.e., SPRT-C; Liu et al., 2022) was found to yield lower levels of correct classification rates than not utilizing it (i.e., SPRT-SF; Seitz & Frey, 2013) under the between-item grid MCCT when the cutoff was set at the mean of the latent trait distribution. This study proposes a pre-rule to determine whether the SPRT-SF or SPRT-C should be used during the process of classification test administration. Through a series of simulation studies, the results showed that our proposed method (called P-SPRT) can substantially improve upon the SPRT-C in terms of correct classification rates, while maintaining its high measurement efficiency in terms of test length. This paper concludes with a discussion of the findings and further applications.
Camping Tourism Experience and
Environmentally Responsible Behavior in Croatia
Authors: Cegur Radović Tihana
Published: January 2025

The purpose of this paper is to determine the impact of different camping tourism experience (TE) dimensions on tourist satisfaction (TS) and the effects of TS on site-specific environmentally responsible behavior (SERB) dimensions. Empirical research was conducted on a convenience sample of 932 tourists in campsites in Croatia. Descriptive and multivariate statistics were used in the data analysis with the software package IBM SPSS Statistic Version 29. Hypotheses were tested using measurement and structural model PLS-SEM in Smart PLS (version 4). The results show that only aesthetics and escapism had a statistically significant influence on TS. Also, TS had a statistically significant influence on SERB dimensions: sustainable behavior on a campsite (SB), responsible behavior towards flora and fauna (RBTF) and responsible use of the products on a campsite (RUP). This research represents a starting point for further research on environmentally responsible behavior (ERB). The results can help managers in campsites to develop strategies to create TE, and through TS, managers can influence the SERB of tourists in campsites.
Does Causality Between
Tourism and Environmental Pollution Depend on Economic Development Level?
Authors: Raifu Isiaka Akande , Ademola Fidelis Obaniyi
Published: January 2025

T his study explored the causal link between tourism and CO2 emissions using bivariate and multivariate causality approaches to analyse data from 134 countries. Employing JKS's Panel Granger non-causality method, we established that tourism significantly Granger-causes environmental pollution. The multivariate model exhibited more robust causality than the bivariate model, yet this causality remains consistent regardless of a country's economic development level. This emphasizes the urgent need to address the interplay between tourism and environmental concerns.

Motive and Method in the Re-Making of the Mineworkers’ Strike, 1984–85
Authors: Beynon Huw
Published: January 2025

Forty years after the UK mineworkers’ strike began, two new books of oral history have been published based on lengthy interviews with ex-mineworkers, miners’ wives, children, and supporters drawn from across the country. Both books are filled with extensive and often vivid quotation reflecting upon the events of the strike and a range of often deeply personal experiences. They are written in contrasting styles, which reflect different methodological approaches and motivations. Robert Gildea is concerned to develop a ‘national story’ from the interviews, one that (with some slight variation) has commonality across the regions and nations of Great Britain. In contrast, Florence Sutcliffe-Braithwaite and Natalie Thomlinson set themselves the task of deconstructing an existing national story, one that describes the involvement of women in the strike in heroic terms, emphasizing some activities and ignoring others. This review critically examines and contrasts these two approaches and places them in the context of the strike as it developed and changed. Drawing upon other materials as well as the author’s own memories and experiences of the strike, it attempts to convey something of the complexity of an event that has had such lasting significance.
Problem-based learning in developing students’ communicative skills and creativity in teaching English for specific purposes

Published: January 2025

Tertiary education uses a variety of teaching methods to cater for different learning styles, encourage critical thinking, and prepare students for real-world challenges. Common methods include lectures, seminars, independent study, and collaborative learning. This diversity reflects the complexity of higher education and helps to create a dynamic learning environment that fosters lifelong learning and critical thinking skills. Problem-based learning, a prominent teaching method, focuses students on an inquiry-based approach, presenting them with real-life problems that require the application of knowledge, critical thinking, creative approach, and collaboration. Problem-based learning is very effective in teaching English for specific purposes at tertiary level because it involves students in projects that require the use of the target language, thus enhancing language acquisition and fostering communicative skills. This method benefits students by promoting active learning, improving communication, encouraging creativity, and developing problem-solving skills. A study at Vilnius Gediminas Technical University, Lithuania, involving students from creative and technical fields, found that most students found problem-based learning beneficial, although creativity students were more enthusiastic. The results suggest that while problem-based learning improves understanding of both theoretical and practical aspects of study programmes, technical students are more sceptical about the effectiveness of problem-based learning. Despite some negative attitudes on the part of some students, problem-based learning remains a valuable tool in English for specific purposes education, supporting the development of language and professional skills.

We conducted a search for new ultracool companions to nearby white dwarfs using multiple methods, including the analysis of colors and examination of images in both the optical and the infrared. Through this process, we identified 51 previously unrecognized systems with candidate ultracool companions. 31 of these systems are resolved in at least one catalog, and all but six are confirmed as comoving companions via common proper motion and consistent parallax measurements (when available). We have followed up four comoving companions with near-infrared spectroscopy and confirm their ultracool nature. The remaining twenty candidates are unresolved, but show clear signs of infrared excess which is most likely due to the presence of a cold, low-mass companion or a dusty circumstellar disk. Three of these unresolved systems have existing optical spectra that clearly show the presence of a cool stellar companion to the white dwarf primary via spectral decomposition. These new discoveries, along with our age estimates for the primary white dwarfs, will serve as valuable benchmark systems for future characterization of ultracool dwarfs.
H-AMR FORGE’d in FIRE. I. Magnetic State Transitions, Jet Launching, and Radiative Emission in Super-Eddington, Highly Magnetized Quasar Disks Formed from Cosmological Initial Conditions
Authors: Kaaz Nicholas , Liska Matthew , Tchekhovskoy Alexander , Hopkins Philip F. , Jacquemin-Ide Jonatan
Published: January 2025

Quasars are powered by supermassive black hole (SMBH) accretion disks, yet standard thin disk models are inconsistent with many observations. Recently, P. F. Hopkins et al. simulated the formation of a quasar disk feeding an SMBH of mass M = 1.3 × 107
M
⊙ in a galaxy. The disk had surprisingly strong toroidal magnetic fields that supported it vertically from gravity and powered rapid accretion. What feedback can such a system produce? To answer this, we must follow the gas to the event horizon. For this, we interpolated the quasar into the general-relativistic radiation magnetohydrodynamics code H-AMR and performed 3D simulations with BH spins a = 0 and a = 0.9375. This remapping generates magnetic monopoles, which we erase using a novel divergence cleaning approach. Despite the toroidal magnetic field's dominance at large radii, vertical magnetic flux builds up near the event horizon, leading to a magnetic state transition within the inner 200 gravitational radii of the disk. This powers strong winds and, for spinning BHs, relativistic jets that can spin down the BH within 5−10 Myr. Sometimes, vertical magnetic fields of opposite polarity reach the BH, causing a polarity inversion event that briefly destroys the jets and, possibly, the X-ray corona. These strong fields power accretion at rates 5× the Eddington limit, which can double the BH mass in 5–10 Myr. When a = 0.9375 (a = 0), the energy in mechanical outflows and radiation equals about 60% (10%) and 100% (3%) of the accreted rest mass energy, respectively. Much of the light escapes in cool, ≳1300 au photospheres, consistent with quasar microlensing and spectral energy distributions.
Fast-rotating A- and F-type Stars with Hα Emissions in NGC 3532: Candidate UV-dim Stars?
Authors: He 贺 Chenyu 辰昱 , Li 李 Chengyuan 程远 , Li 李 Gang 刚
Published: January 2025

Extended main-sequence stars that are dim in the ultraviolet passbands of the Hubble Space Telescope (UV-dim stars) are found in several young and intermediate-age star clusters in the Magellanic Clouds (MCs). The obscuring of the dust in the disks of stars expelled as a result of fast rotation has been suggested to be responsible for the appearance of UV-dim stars and to play an important role in the formation of extended main sequences. In this paper, we report a population of A- and F-type stars that show Hα emission features in their spectra in the young (~340 Myr old) neighboring Galactic star cluster NGC 3532. By fitting the observed absorption profiles, we found that most Hα emitters are fast-rotating stars, indicating that they form decretion disks by fast rotation like Be stars. As A- and F-type stars dominate the extended main-sequence turnoff regions of intermediate-age clusters, their appearance provides observational evidence to support the dust extinction scenario for these clusters, and they might be the counterparts of UV-dim stars that are detected in remote MC star clusters such as NGC 1783.
HCG 57: Evidence for Shock-heated Intergalactic Gas from X-Rays and Optical Emission Line Spectroscopy

Published: January 2025

We present Chandra and XMM-Newton X-ray observations of the compact group HCG 57, and optical integral field spectroscopy of the interacting galaxy pair HCG 57A/D. These two spiral galaxies recently suffered an off-axis collision with HCG 57D passing through the disk of A. We find evidence of a gas bridge linking the galaxies, containing ∼108
M
⊙ of hot, ∼1 keV thermal plasma and warm ionized gas radiating in Hα, Hβ, [O iii] and [N ii] lines. The optical emission lines in the central regions of HCG 57D show excitation properties consistent with H ii-regions, while the outer rim of HCG 57D parts of the bridge and the outer regions of HCG 57A show evidence of shocked gas consistent with shock velocities of 200–300 km s−1. In contrast, the X-ray emitting gas requires a collision velocity of 650–750 km s−1 to explain the observed temperatures. These different shock velocities can be reconciled by considering the contributions of rotation to collision velocity in different parts of the disks, and the clumpy nature of the preshock medium in the galaxies, which likely lead to different shock velocities in different components of the turbulent postshocked gas. We examine the diffuse X-ray emission in the group members and their associated point sources, identifying X-ray active galactic nuclei in HCG 57A, B, and D. We also confirm the previously reported ∼1 keV intra-group medium and find it to be relaxed with a low central entropy (18.0 ± 1.7 keV cm2 within 20 kpc) but a long cooling time (5.9 ± 0.8 Gyr).
Exploring the Evolution of a Dwarf Spheroidal Galaxy with SPH Simulations. II. AGN Feedback
Authors: Hazenfratz Roberto , Barai Paramita , Lanfranchi Gustavo A. , Caproni Anderson
Published: January 2025

We investigate active galactic nucleus (AGN) feedback from an intermediate-mass black hole at the center of a dwarf spheroidal galaxy, by performing isolated galaxy simulations using a modified version of the GADGET-3 code. We consider Leo II (PGC 34176) in the Local Group as our simulation reference model. Beginning with black hole seeds ranging from 103−106
M
⊙, our simulations focus on comparing stellar/SN-only feedback with AGN+stellar/SN feedback over 13.7 Gyr of galactic evolution. Our results indicate that a low-mass AGN in a dwarf galaxy influences the star formation history under specific physical conditions. While AGN feedback is generally negative on star formation, instances of positive feedback were also identified. Despite measurable effects on the evolution of the dwarf host galaxy, black hole seeds exhibited only marginal growth. We tested several physical scenarios as modified models in our simulations, primarily concerning the dynamics of the central black holes, which may wander within dwarf galaxies rather than being centrally located. However, none of these adjustments significantly impacted the growth of the black hole seeds. This suggests that intermediate-mass black holes may struggle to achieve higher masses in isolated environments, with mergers and interactions likely playing crucial roles in their growth. Nevertheless, AGN feedback exhibited nonnegligible effects in our simulated dwarf spheroidal galaxies, despite the assumed dominant role of stellar feedback in the low-mass regime.
Black Hole Accretion and Spin-up through Stellar Collisions in Dense Star Clusters

Published: January 2025

Dynamical interactions in dense star clusters could significantly influence the properties of black holes, leaving imprints on their gravitational-wave signatures. While previous studies have mostly focused on repeated black hole mergers for spin and mass growth, this work examines the impact of physical collisions and close encounters between black holes and (noncompact) stars. Using Monte Carlo N-body models of dense star clusters, we find that a large fraction of black holes retained upon formation undergo collisions with stars. Within our explored cluster models, the proportion of binary black hole mergers affected by stellar collisions ranges from 10%–60%. If all stellar-mass black holes are initially nonspinning, we find that up to 40% of merging binary black holes may have components with dimensionless spin parameter χ ≳ 0.2 because of prior stellar collisions, while typically about 10% have spins near χ = 0.7 from prior black hole mergers. We demonstrate that young star clusters are especially important environments, as they can produce collisions of black holes with very massive stars, allowing for significant spin-up of the black holes through accretion. Our predictions for black hole spin distributions from these stellar collisions highlight their sensitivity to accretion efficiency, underscoring the need for detailed hydrodynamic calculations to better understand the accretion physics following these interactions.
Reverberation Evidence for Stream Collision and Delayed Disk Formation in Tidal Disruption Events

Published: January 2025

When a star passes through the tidal disruption radius of a massive black hole (BH), it can be torn apart by the tidal force of the BH, known as the tidal disruption event (TDE). Since the observed UV/optical luminosity significantly exceeds the predictions of the compact disk model in classical TDE theory, two competing models, stream collision and envelope reprocessing, have been proposed to address this discrepancy. To distinguish between these models, we investigated the continuum reverberation behaviors for ~30 TDEs with high-quality multiband light curves. We found that over half of them exhibit a positive lag by a few days in UV/optical bands, indicating that their inferred sizes are significantly larger than the envelope sizes in reprocessing. Moreover, X-ray emissions are not only significantly delayed relative to the primary UV/optical peak but also lag behind the rebrightening bump by up to several tens of days, completely different from the X-ray illumination reprocessing. Additionally, the anticorrelated UV−optical continuum in ASASSN-15lh further disfavors the reprocessing scenario. In contrast, the model of stream collisions, combined with delayed accretion disk formation, can provide a unified explanation for the diverse TDE observations, e.g., the optical/X-ray population and the frequently observed rebrightening bump. This model describes a unification scheme wherein the UV/optical emission originates from stream collisions during the early stage of TDE evolution and gradually transitions to being dominated by a accretion disk with detectable X-ray emission in the late stage. After transitioning to a quiescent state, recurrent flares may be observed in some cases, possibly related to repeating partial TDEs.
Secular Perturbations from Exterior Giants Strongly Influence Gap Complexity in Peas-in-a-pod Exoplanetary Systems
Authors: Livesey Joseph R. , Becker Juliette
Published: January 2025

It has been demonstrated that systems of tightly packed inner planets with giant exterior companions tend to have less regular orbital spacings than those without such companions. We investigate whether this observed increase in the gap complexity of the inner systems can be explained solely as the result of secular dynamics caused by the disturbing potential of the exterior companions. Amplification of mutual orbital inclinations in the inner system due to such secular dynamics may lead to the inner system attaining nonmutually transiting geometries, thereby creating artificial observed gaps that result in a higher calculated gap complexity. Using second-order secular theory, we compute time-averaged observed gap complexities along a favorable line of sight for a set of hypothetical systems, both with and without an outer giant. We find that these secular interactions can significantly contribute to the observed gap complexity dichotomy in tightly packed multiple-planet systems.
Quasi-parallel Antisunward-propagating Whistler Waves Associated with the Electron Deficit in the Near-Sun Solar Wind: Particle-in-cell Simulation
Authors: Micera Alfredo , Verscharen Daniel , Coburn Jesse T. , Innocenti Maria Elena
Published: January 2025

In situ observations of the solar wind have shown that the electron velocity distribution function (VDF) consists of a quasi-Maxwellian core, comprising most of the electron population, and two sparser components: the halo, which are suprathermal and quasi-isotropic electrons, and an escaping beam population, the strahl. Recent Parker Solar Probe (PSP) and Solar Orbiter (SO) observations have added one more ingredient to the known nonthermal features, the deficit—a depletion in the sunward region of the VDF, already predicted by exospheric models but never so extensively observed. By employing particle-in-cell simulations, we study electron VDFs that reproduce those typically observed in the inner heliosphere and investigate whether the electron deficit may contribute to the onset of kinetic instabilities. Previous studies and in situ observations show that strahl electrons drive oblique whistler waves unstable, which in turn scatters them. As a result, suprathermal electrons can occupy regions of phase space where they fulfill resonance conditions with the parallel-propagating whistler wave. The suprathermal electrons lose kinetic energy, resulting in the generation of unstable waves. The sunward side of the VDF, initially depleted of electrons, is gradually filled, as this wave−particle interaction process, triggered by the depletion itself, takes place. Our findings are compared and validated against current PSP and SO observations: among others, our study provides a mechanism explaining the presence in the heliosphere of regularly observed parallel antisunward whistler waves, suggests why these waves are frequently observed concomitant with distributions presenting an electron deficit, and describes a noncollisional heat flux regulating process.
Uncorrelated Estimations of H0 Redshift Evolution from DESI Baryon Acoustic Oscillation Observations
Authors: Jia X. D. , Hu J. P. , Yi S. X. , Wang F. Y.
Published: January 2025

The Dark Energy Spectroscopic Instrument (DESI) collaboration recently released the first-year data of baryon acoustic oscillations (BAOs). Based on the five different tracers, the cosmological constraint shows a hint of deviation from the standard ΛCDM model. In this Letter, we combine the DESI BAOs with other cosmic probes to constrain the evolution of the Hubble constant as a function of redshift in the flat ΛCDM model. The nonparametric method is used to estimate the value of the Hubble constant at different redshift bins. The correlations among different bins are removed by diagonalizing the covariance matrix. The joint data sample demonstrates a decreasing trend of the Hubble constant with a significance of 6.4σ, which can naturally resolve the Hubble tension. To avoid statistical effects caused by the binning methods, we tested three other different binning methods and also found a decreasing trend. It may be due to dynamical dark energy or modified gravity.
Will Nanodust Reappear in STEREO/WAVES Data?
Authors: Meyer-Vernet Nicole
Published: January 2025

Nanodust particles produced near the Sun by collisional breakup of larger grains are accelerated in the magnetised solar wind and reach high speeds outwards of 1 au. Vaporisation and ionization of fast dust grains impacting a spacecraft produce voltage pulses on wave instruments that enable them to act as dust detectors. Wave instruments on STEREO and on Cassini during its cruise phase detected a highly variable flux of fast nanodust. Both detections took place when the orientation of the solar magnetic dipole produced an interplanetary electric field that focused nanoparticles towards the heliospheric current sheet—a geometry that is recurring because of the periodicity of solar activity.

Community of Inquiry-Guided Design of Asynchronous Online Continuing Professional Development for Pediatric Nurses
Authors: Davis Clare , Posey Laurie , Mtolo Nonhlanhla , Webber Ilana , White Lee-Ann , Coetzee Minette
Published: January 2025

Background

Nurses play a pivotal role in the provision of health care for children across Africa. With limited pediatric nursing content in undergraduate nursing programs and few available pediatric postgraduate nursing programs, there is a need for additional continuing professional development opportunities to prepare nurses with the knowledge, skills, and confidence needed to care for children.

Method

To address this need, and mindful of the unique profile of potential participants, the Children's Nursing Development Unit at the University of Cape Town developed a suite of asynchronous short online courses. Course design was grounded in the Community of Inquiry framework, a widely adopted and researched framework that integrates cognitive, social, and teaching presences for optimal online learning.

Results

This article illustrates how the three Community of Inquiry presences were integrated into the courses.

Conclusion

As evidenced by the examples, nurse educators effectively used the Community of Inquiry framework to create deep and meaningful learning experiences in an asynchronous online professional development program for pediatric nurses.

Effect of Assertive Communication Training on the Confidence of New Graduate Nurses
Authors: Zwilling Elizabeth A. , Osborne Jason W.
Published: January 2025

Background

New graduate nurses (NGNs) often face challenges during conflicts with health care providers, fellow nurses, and patients.

Method

A pilot educational session was created to address conflict challenges in communication. The session discussed assertive communication, communication tools to be used in practice, and video simulations with standardized clients.

Results

A total of 17 NGNs in a transition to practice program completed the pretest, educational session, and posttest measuring confidence in managing conflicts. The NGNs rated their belief in their ability to be assertive in communication, and a significant improvement in confidence was seen from pre- to posttest. Specifically, NGNs reported an 18.03% increase in confidence when discussing difficult care decisions with health care providers and a 20.07% increase when discussing decisions with more experienced nurses. Posttest qualitative vignettes supported these quantitative findings, highlighting NGNs' growing confidence in advocating for patient care concerns.

Conclusion

Educational interventions similar to this one may benefit other transition to practice programs and prelicensure nursing programs.

Expected balanced uncertain utility
Authors: Grant Simon , Roorda Berend , Yang Jingni
Published: January 2025

We introduce and analyze
expected balanced uncertain utility (EBUU) theory. A prior and a
balanced outcome‐set utility characterize an EBUU decision maker. Conditional on a reference or “balancing value,” the latter assigns a utility to each outcome‐set. The decision maker associates with each act, its
envelope, the minimal measurable mapping from states to outcome‐sets that contains the act. She then (implicitly) ranks an act according to the balancing value at which the expected balanced utility of its associated envelope is zero. As a consequence, her risk preferences need only exhibit betweenness allowing for behavior that can accommodate Allais‐type paradoxes.

This paper studies repeated trade with noisy information about previous transactions. A buyer has private information about his willingness to pay, which is either low or high, and buys goods from different sellers over time. Each seller observes a noisy history of signals about the buyer's previous purchases and sets a price. We compare the cases where previous prices are observable to sellers with the case where they are not. We show that, in both cases, more signal precision is counterbalanced in equilibrium by less separation between types, either because (1) sellers offer discounted prices more often, which are accepted by both types, or (2) the buyer with a high valuation rejects high prices with a higher probability. The effect on welfare and efficiency of making prices observable depends on the signal precision: When the signal is imprecise, making prices public strengthens the discounting mechanism, improving efficiency and buyer welfare; when the signal is precise, making prices public activates the rejection mechanism, and efficiency and buyer welfare may decrease. Independently of price observability, the buyer tends to benefit from a more precise signal about previous purchases.
Radical Theology and the “Weakening” of Bourgeois Institutions
Authors: Grimshaw Michael
Published: January 2025

Radical theology offers a different way to interrogate and critique bourgeois capitalist society and its institutions. Almost always institutional in location and focus, radical theology recognizes that the traditional religious underpinnings of liberal bourgeois society and its institutions no longer continue to operate nor offer a workable foundational basis. We could say, contra Habermas, that there is more than “the awareness” of what is missing; rather, what is missing is what is necessarily missing because “the what” of God is dead. The crisis of contemporary institutions is that, founded implicitly or explicitly on bourgeois religion and its God, they now find themselves with an ontological crisis most do not even recognize. Or rather, they recognize there is a crisis of meaning and purpose but are unsure or unwilling or even unable to engage with its foundational causes. Drawing on the weak thought of Gianni Vattimo, radical theology is empoyed as a way of rethinking institutions from within, against both their foundations and their current expressions, articulating a set of “weak possibilities” for ways forward.
Rough Cuts
Authors: Zeiher Cindy
Published: January 2025

Vladimir Jankélévitch allows us to rethink the relation between negation and refusal as a rift where one is confronted by the repetition of givenness and where refusal upends negation by turning the object being refused into an ineffable question. Here we turn to Freud as a reader of Jankélévitch’s refusal of German culture in order to consider his procedure of radical exclusion as a matter of idealistic temperament marking a transition from knowledge as “knowing how things are” to a different proposition which cultivates knowing “how things should be.”

Erasure as a Constitutive Mechanism of Global Capitalism
Authors: Cvar Nina
Published: January 2025

Fredrikzon and Haffenden (2023) argue that the so-called notion of erasure has remained largely under-researched. But what does erasure mean—how does it operate and how is it reproduced, particularly in relation to global capitalism? Contrary to the inclination to individualize the repressive character of erasure, this text will aspire to thematize erasure as a constitutive mechanism of global capitalism that permeates its logic. Stemming from distinct disciplinary areas yet which intersect in various ways, this research will therefore investigate erasure as a notion that is not isolated but related to its political, social, cultural, physical, and technological dimensions and processes that give meaning to it within a temporal horizon. Thus, the central thesis of this paper will be that the process of erasure needs to be understood as the essential element of modernity, appearing uncompromisingly in its histories and in particular in contemporary politics.
The Con-Fusion of Artificial Intelligence
Authors: Mendiževec Aleš
Published: January 2025

The article discusses various conditions of contemporary artificial intelligence, namely deep learning mechanisms, to emphasize its limitations and argues for an antihumanistic view of contemporary technology. It starts from affirming Turing test and argues that machines can in fact be intelligent but that this intelligence must not be related to a capitalistically hyped idea of artificial general intelligence. Then it outlines various conditions on which deep learning depends in its functioning (brute computing power, capitalist datafication, the world of contingency). These conditions show an epistemological schism in the field of artificial intelligence (between symbolic AI and connectionism) that could be overcome by getting rid of the idea of artificial general intelligence and the competitive relation between humans and machines.
La stratification sociale des campagnes de l’Ouest : le cas du Haut-Maine / de la Sarthe, 1720-1815
Authors: Musset Benoît
Published: January 2025

Les sociétés rurales de l’Ouest, marquées par un système de polyculture orienté vers l’élevage, sont caractérisées par l’existence d’une vaste classe d’exploitants agricoles moyens, appelés bordagers (Sarthe), bordiers ou encore closiers. Néanmoins, la société rurale, composée de deux autres catégories de travailleurs de la terre (les journaliers et les laboureurs), est très inégalitaire. La majorité des terres est possédée par le clergé, la noblesse, les bourgeois des villes mais aussi par beaucoup de petits rentiers ruraux. Les 10 % les plus riches voient leur part du patrimoine immobilier et mobilier croître dans les années 1760-1815, s’appropriant 65 % du total. Les bordagers forment en effet une classe moyenne, exposée à la domination économique des laboureurs, qui louent les plus belles exploitations (métairies) et occupent une position dominante dans le monde agricole. Les journaliers forment quant à eux un prolétariat rural, fragile et mobile. Ces catégories sociales rurales ont parfois des intérêts divergents, qui se manifestent durant les débuts de la Révolution.
La sériciculture, un révélateur des jeux de pouvoir dans les sociétés rurales françaises au xviiie siècle
Authors: Vérot Jean-Baptiste
Published: January 2025

Cet article explore le rôle de la sériciculture comme révélateur des jeux de pouvoir dans les sociétés rurales françaises au xviiie siècle. Il examine comment, dans les régions séricicoles, le développement de la culture du mûrier et de l’élevage des vers à soie a modifié les rapports de force et de domination, notamment entre grands propriétaires et petits exploitants, entre hommes et femmes, ou encore entre seigneurs et communautés. Dans les territoires où l’État royal cherche à implanter la sériciculture ex nihilo, l’analyse met en lumière les tensions liées aux efforts – souvent confrontés à des résistances locales – de l’administration royale pour gouverner les campagnes.
Réquisitions, marché noir et colis familiaux
Authors: Lyautey Margot
Published: January 2025

Dans le cadre de la question d’agrégation externe « Vivre à la campagne en France de 1815 aux années 1970 », le présent article traite d’un aspect particulier de la vie durant la Seconde Guerre mondiale, le rationnement, afin d’en expliciter les effets dans les campagnes françaises. Pensé comme une synthèse des travaux majeurs sur le sujet, il permet d’aborder l’histoire des campagnes françaises de cette guerre dans une perspective d’histoire du quotidien, « au ras du sol », comme le propose la lettre de cadrage du concours. L’article aborde la mise en place des premières mesures de rationnement au début de la guerre et les effets des rations insuffisantes sur les citadins, puis traite des divers contournements du Ravitaillement général et du développement de filières clandestines, où les ruraux jouent un rôle majeur. Il analyse enfin le rapport de Vichy à la paysannerie, l’échec de sa politique de ravitaillement, et la poursuite des mesures de rationnement malgré la fin de la guerre et de l’Occupation.
Les sociétés rurales face aux risques naturels. Les secours des pouvoirs
Authors: Lachaud Stéphanie
Published: January 2025

On a souvent dit des sociétés anciennes qu’elles étaient des sociétés sans risque, dans le sens où elles restaient soumises à des menaces qu’elles ne pouvaient ni mesurer ni anticiper. Or, les risques naturels (aléas météorologiques, animaux, etc.) ont une grande place dans la vie quotidienne des campagnes modernes, en raison de leurs répercussions sur les récoltes et sur l’économie agraire et la vie des populations. L’époque moderne se caractérise même par la construction d’un discours neuf sur les expériences vécues, lié aux pratiques émergentes de secours. Au‑delà du discours, les formes de prévoyance et les actions au moment des difficultés participèrent à construire une nouvelle manière de penser le rapport à l’environnement et un rapport plus complexe avec les pouvoirs qui encadrent les sociétés rurales. Ainsi, les xviie‑xviiie siècles sont marqués par deux grandes tendances : d’une part la volonté de comprendre pour agir, d’autre part l’attente de secours plutôt que l’acceptation d’une forme de fatalité, avec une émancipation du pouvoir explicatif de l’Église et un besoin accru de celui de l’État royal.
Le « fruit du marin » : usages et représentations de la noix de coco dans les sociétés maritimes de l’époque moderne (xviie-xixe siècle)
Authors: Dieulefet Gaëlle , Le Guen Denis
Published: January 2025

La mention et la découverte de noix de coco dans les archives et en contexte archéologique, ainsi que son importance dans les récits de voyage amènent les auteurs de cet article à s’interroger sur la représentation et l’usage de cet objet dans les sociétés maritimes de l’époque moderne. Ils se proposent de l’étudier, non pas seulement comme le témoin des grandes expéditions maritimes de la première mondialisation, mais comme un objet d’étude en soi. La présence récurrente de ce fruit et les différentes formes que peuvent prendre son usage disent quelque chose du rapport des sociétés passées à la mer et au monde. Cet article retrace, dans cette perspective, l’itinéraire de la noix de coco, son réemploi et sa conservation comme objet-mémoire.
Auguste de Silz et la chouannerie du Morbihan
Authors: Le Masne Camille , Le Masne Pierre
Published: January 2025

Au travers de la personne d’Auguste de Silz, premier chef chouan du Morbihan, l’article s’attache à la contre-révolution bretonne, aux relations entre la conjuration La Rouërie et l’insurrection de 1793, aux conflits entre les chefs locaux du Morbihan en 1794-95, au débarquement de Quiberon, enfin à la politique de pacification du général Hoche. Après la reddition de 1796, Auguste de Silz est pris dans un conflit qui dure jusqu’en 1799 entre le département du Morbihan d’un côté, le Directoire et le général Hoche d’autre part. Il est emprisonné à Vannes puis à la forteresse de l’ile de Ré en vue d’une déportation en Guyane.
