description: We present a new analytic model describing gravitational wave emission in the post-merger phase of binary neutron star mergers. The model is described by a number of physical parameters that are related to various oscillation modes, quasi-linear combination tones or non-linear features that appear in the post-merger phase. The time evolution of the main post-merger frequency peak is taken into account and it is described by a two-segment linear expression. The effectiveness of the model, in terms of the fitting factor or, equivalently, the reduction in the detection rate, is evaluated along a sequence of equal-mass simulations of varying mass. We find that all parameters of the analytic model correlate with the total binary mass of the system. For high masses, we identify new spectral features originating from the non-linear coupling between the quasi-radial oscillation and the antipodal tidal deformation, the inclusion of which significantly improves the fitting factors achieved by the model. We can thus model the post-merger gravitational-wave emission with an analytic model that achieves high fitting factors for a wide range of total binary masses. Our model can be used for the detection and parameter estimation of the post-merger phase in upcoming searches with upgraded second-generation detectors, such as aLIGO+ and aVirgo+, with future, third-generation detectors (Einstein Telescope and Cosmic Explorer) or with dedicated, high-frequency detectors.

description: Nature-based solutions for climate protection and more: Nature-based Solutions create and maintain resilient ecosystems. They contribute significantly to climate protection. In addition, they have other positive effects, especially for climate adaptation and for the preservation and promotion of biodiversity. Nature-based solutions are proving to be economic and sustainable measures that can be used to address the crises of the time. At all levels, international, EU-European, national and local, these measures must not be neglected. Since Nature-based Solutions might need a longer implementation phase, they must be pursued as quickly as possible, so that they manifest their long-term positive effects on climate, nature and people.

description: We show that a two-dimensional hydrodynamics model provides a physical explanation for the splitting of higher-charge optical vortices under elliptical deformations. The model is applicable to laser light and quantum fluids alike. The study delineates vortex breakups from vortex unions under different forms of asymmetry in the beam, and it is also applied to explain the motion of intact higher-charge vortices.
General truncated linear statistics for the top eigenvalues of random matrices

description: Invariant ensemble, which are characterised by the joint distribution of eigenvalues $P(λ_1,\ldots,λ_N)$, play a central role in random matrix theory. We consider the truncated linear statistics $L_K = \sum_{n=1}^K f(λ_n)$ with $1 \leq K \leq N$, $λ_1 > λ_2 > \cdots > λ_N$ and $f$ a given function. This quantity has been studied recently in the case where the function $f$ is monotonous. Here, we consider the general case, where this function can be non-monotonous. Motivated by the physics of cold atoms, we study the example $f(λ)=λ^2$ in the Gaussian ensembles of random matrix theory. Using the Coulomb gas method, we obtain the distribution of the truncated linear statistics, in the limit $N \to \infty$ and $K \to \infty$, with $κ= K/N$ fixed. We show that the distribution presents two essential singularities, which arise from two infinite order phase transitions for the underlying Coulomb gas. We further argue that this mechanism is universal, as it depends neither on the choice of the ensemble, nor on the function $f$.

description: This article fills the limited statistical understanding of Shapley values as a variable importance measure from a nonparametric (or smoothing) perspective. We introduce population-level Shapley curves to measure the true variable importance, determined by the conditional expectation function and the distribution of covariates. Having defined the estimand, we derive minimax convergence rates and asymptotic normality under general conditions for the two leading estimation strategies. For finite sample inference, we propose a novel version of the wild bootstrap procedure tailored for capturing lower-order terms in the estimation of Shapley curves. Numerical studies confirm our theoretical findings, and an empirical application analyzes the determining factors of vehicle prices.
Aspects of 5d Seiberg-Witten Theories on $\mathbb{S}^1$

description: We study the infrared physics of 5d $\cal N=1$ Yang-Mills theories compactified on $\mathbb{S}^1$, with a view toward 4d and 5d limits. Global structures of the simplest Coulombic moduli spaces are outlined, with an emphasis on how multiple planar 4d Seiberg-Witten geometries are embedded in the cigar geometry of a single 5d theory on $\mathbb{S}^1$. The Coulomb phase boundaries in the decompactification limit are given particular attention and related to how the wall-crossings by 5d BPS particles turn off. On the other hand, the elliptic genera of magnetic BPS strings do wall-cross and retain the memory of 4d wall-crossings, which we review with the example of dP$_2$ theory. Along the way, we also offer a general field theory proof of the odd shift of electric charge on Sp$(k)_π$ instanton solitons, previously observed via geometric engineering for low-rank supersymmetric theories.

Le personnel soignant est en contact direct avec le patient et peut être amené à gérer des situations critiques, qui peuvent être parfois violentes. Le sujet de la violence suscite notreintérêt et soulève un questionnement car, dans un premier temps, il ne semble pas être de pair avec le lieu où l’on vient se faire soigner. Cependant, cela peut être courant dans certainessituations et peut contribuer à sa banalisation.Durant nos études, nous avons eu des cours liés à la thématique de la violence et de l’agressivité qui ont suscité davantage notre intérêt sur le sujet. En effet, nous avons pu suivre un cours sur la thématique des violences aux urgences qui nous a questionné sur les conditions de travail d’une profession qui sera bientôt la nôtre. Lorsque l’on s’engage comme infirmière, l’idée de venir en aide aux patients et les soigner n’est pas associée avec l’idéed’être insultée, injuriée, menacée, bousculée ou frappée. Ces éléments peuvent créer des appréhensions de notre part et nous questionner sur la manière de prendre en soin le patient,l’impact au niveau de la qualité des soins, l’accès aux soins mais également sur les conditions de travail ainsi que la santé mentale des professionnels.

description: Dark matter direct detection experiments mostly operate at deep underground laboratories. It is necessary to consider shielding effect of the Earth, especially for dark matter particles interacting with a large cross section. We analyzed and simulated the Earth shielding effect for dark matter at the China Jinping Underground Laboratory (CJPL) with a simulation package, CJPL Earth Shielding Simulation code (CJPL\_ESS), which is applicable to other underground locations. The further constraints on the $χ$-N cross section exclusion regions are derived based on the studies with CDEX experiment data.

description: This is an abstract from the session entitled "Historical Archaeology of Cities: Unearthing Complexity in Urban Landscapes", at the 2023 annual meeting of the Society for Historical Archaeology. From the archaeological study and enhancement of "urban ruin", understood as an interpretive tool for the assessment of recent materiality, a disordered and poorly defined range of traces of the industrialization process and its consequences can be involved to account for the particularities of the urban historical configuration of the western sector of Bogotá city, which has historically been established as a marginal, commercial and industrial place. The urban ruins of this sector are forgotten and in state of deterioration due to lack of recognition and appropriation of heritage. The sociocultural actors and the patrimonial valuation policies of movable/immovable property are related to this type of ruins, among them abandonment, segregation, marginality, ignorance, and disinterest. This research objective is to strengthen the historical knowledge of this sector of Bogotá between the end of the 19th and the beginning of the 20th century from an interdisciplinary approach (archaeological, ethnographic, historical perspective).

description: Gravitational collapse into a black hole has been extensively studied with classical sources. We develop a new formalism to simulate quantum fields forming a black hole. By choosing a convenient coherent state, this formalism taps into well-established techniques used for classical collapse and adds on the evolution of the mode functions of the quantum field operator. Divergences are regularized with the cosmological constant and Pauli-Villars fields. Using a massless spherically symmetric scalar field as an example, we demonstrate the effectiveness of the formalism by reproducing some classical results in gravitational collapse, and identifying the difference due to the quantum effects. We also find that Choptuik scaling in critical collapse survives in the semiclassical simulation, and furthermore the quantum deviation from the classical Choptuik scaling decreases when the system approaches the critical point.

description: We explore a family of generalised scalar-tensor theories that exhibit self-tuning to low scale anti de Sitter vacua, even in the presence of a large cosmological constant. We are able to examine the linearised fluctuations about these vacua and compute the corresponding amplitude. Thanks to a subtle interplay between a weak scalar coupling and a low scalar mass, it is possible to exhibit self-tuning and compatibility with solar system tests of gravity without resorting to non-linearities and unreliable screening mechanisms. The weakness of the scalar coupling and the correspondingly slow response to vacuum energy phase transitions may present some interesting possibilities for connecting early universe inflation to the cancellation of vacuum energy.

Abstract: The Compact Linear Collider (CLIC) is a TeV-scale high-luminosity linear e+e− collider under development at CERN. Following the CLIC conceptual design published in 2012, this report provides an overview of the CLIC project, its current status, and future developments. It presents the CLIC physics potential and reports on design, technology, and implementation aspects of the accelerator and the detector. CLIC is foreseen to be built and operated in stages, at centre-of-mass energies of 380 GeV, 1.5 TeV and 3 TeV, respectively. CLIC uses a two-beam acceleration scheme, in which 12 GHz accelerating structures are powered via a high-current drive beam. For the first stage, an alternative with X-band klystron powering is also considered. CLIC accelerator optimisation, technical developments and system tests have resulted in an increased energy efficiency (power around 170 MW) for the 380 GeV stage, together with a reduced cost estimate at the level of 6 billion CHF. The detector concept has been refined using improved software tools. Significant progress has been made on detector technology developments for the tracking and calorimetry systems. A wide range of CLIC physics studies has been conducted, both through full detector simulations and parametric studies, together providing a broad overview of the CLIC physics potential. Each of the three energy stages adds cornerstones of the full CLIC physics programme, such as Higgs width and couplings, top-quark properties, Higgs self-coupling, direct searches, and many precision electroweak measurements. The interpretation of the combined results gives crucial and accurate insight into new physics, largely complementary to LHC and HL-LHC. The construction of the first CLIC energy stage could start by 2026. First beams would be available by 2035, marking the beginning of a broad CLIC physics programme spanning 25-30 years.

description: In this paper, we reported the synthesis of a novel series of (2-hydroxyphenyl)-5-phenyl-6-(pyrrolidine-1-carbonyl)-1H-pyrano[2,3-d]pyrimidine-2,4(3H,5H)-dione derivatives 5(a–j) by the reaction of 4-hydroxy coumarin, substituted aldehydes, barbituric acid, and pyrolidine in ethanol at ambient temperature. The titled pyranopyrimidines 5(a–j) were characterized by spectral analysis including IR, NMR (1H & 13C), and HRMS. The newly synthesized compounds were examined for in vitro anti-inflammatory activity. The results demonstrated that compound 5b displayed excellent efficacy and the remaining compounds exhibited moderate activity. Also, the potency of the new compounds toward antimicrobial and antifungal activity was investigated by a disk diffusion method. The results show that compounds 5b and 5g were more potent than the other compounds. Furthermore, the molecular docking studies were carried out using a COX-2 receptor.
D4.1 Report on co-design of the AI-Assisted Platform with stakeholders' community
Creators: name: Glumac, Olga

Publisher: name: Zenodo
Year: 2024

description: This document sets out the report on the co-design of AI-assisted platform user experience (D4.1) for the D4RUNOFF project and its three case studies in Bolbro (Denmark), Pontedera (Italy) and Santander (Spain). It also addresses specific objective (SO) 5 – Development of an AI-assisted platform to facilitate the development of effective urban runoff and stormwater management plans based on informed decisions.

D4RUNOFF is a three-and-a-half-year project funded by the European Commission under the Horizon Europe Climate, Energy and Mobility programme and coordinated by VandCenter Syd. The consortium consists of 13 organisations from Denmark, Spain, Portugal, France, and Italy, with leading experts in innovative water management systems, healthy water environments, civil engineers, interdisciplinary scientists and AI specialists. The overall goal of D4RUNOFF is to create a novel framework for preventing and managing diffuse pollution from urban water runoff.

D4RUNOFF is developing an AI-assisted platform (D4RUNOFF platform) to support multi-criteria decision-making based on data extracted from online sensors and other sources so that stormwater pollution issues could be addressed through the complete or partial application of nature-based solutions (NBS) as a systemic approach to stormwater pollution prevention and purification.

This document will cover the following elements:

• Methodology for co-design of stakeholders‘ journeys• Synthesis of results in each of the case studies• Prototypes (storyboards and mock-ups)• Lessons learnt and recommendations for the development of the D4RUNOFF platform

Deliverable 4.1 was concluded and submitted in April 2023 by 3OC with the support of ITG and VCS as the reviewers and KLK, ING TOS, UC, AQU and VCS as active contributors of the case studies.

description: Employing the QCD factorization formalism we compute $B_{u}^{-} \to γ^{\ast} \, \ell \, \bar ν_{\ell}$ form factors with an off-shell photon state possessing the virtuality of order $m_b \, Λ_{\rm QCD}$ and $m_b^2$, respectively, at next-to-leading order in QCD. Perturbative resummation for the enhanced logarithms of $m_b / Λ_{\rm QCD}$ in the resulting factorization formulae is subsequently accomplished at next-to-leading logarithmic accuracy with the renormalization-group technique in momentum space. In particular, we derive the soft-collinear factorization formulae for a variety of the subleading power corrections to the exclusive radiative $B_{u}^{-} \to γ^{\ast} \, W^{\ast}$ form factors with a hard-collinear photon at ${\cal O}(α_s^{0})$. We further construct the complete set of the angular observables governing the full differential distribution of the four-body leptonic decays $B_{u}^{-} \to \ell^{\prime} \, \bar \ell^{\prime} \, \ell \, \bar ν_{\ell}$ with $\ell, \, \ell^{\prime} \in \{ e, \, μ\}$ and then perform an exploratory phenomenological analysis for a number of decay observables accessible at the LHCb and Belle II experiments, with an emphasis on the systematic uncertainties arising from the shape parameters of the leading-twist $B$-meson light-cone distribution amplitude in heavy quark effective theory.

The effective dynamics of weak coupling loop quantum gravity
Creators: name: Long, Gaoping

Publisher: name: arXiv
Year: 2021
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: By taking the limit that Newton's Gravitational constant tends to zero, the weak coupling loop quantum gravity can be formulated as a $U(1)^3$ gauge theory instead of the original $SU(2)$ gauge theory. In this paper, a parametrization of the $SU(2)$ holonomy-flux variables by the $U(1)^3$ holonomy-flux variables is introduced, and the Hamiltonian operator based on this parametrization is obtained for the weak coupling loop quantum gravity. It is shown that the effective dynamics obtained from the coherent state path integrals in $U(1)^3$ and $SU(2)$ loop quantum gravity respectively are consistent to each other in the weak coupling limit, provided that the expectation values of the Hamiltonian operators on the coherent states in these two theories coincide with their classical expressions respectively.

The Nomadic Subject in Student Organizing

description: There is significant interest in the way that collective subjectivities emerge, and in how they negotiate power to create change. Through a discussion of work that I have done with the Red Square Movement (a national student network organising for a radically different educational system in the UK) I argue that the posthuman theorist Braidotti’s conception of the nomadic subject is a compelling conceptual lens by which to read this activity. Drawing on my experiences, I suggest that the nomad is greatly strengthened when she works transversally, and thus alongside both the comrade and the non-nomad. This research has taken place as part of my doctorate and uses a militant research methodology.

The natural, dried and preserved flowers offering lasting value that can be cherished over an extended period (Sheela, 2008). The dry flower industry has emerged as a significant sector for export, accounting for 15% of the global floral market. The Netherlands leads in exporting dried flowers to the USA, followed by Mexico, India, Colombia and Israel. Major dry flower exported from India are rose petals, marigold flowers, chrysanthemum, carnation, jasmine buds, lavender flowers and babys breath used in otpurries, wreaths, floral arrangements and crafts that are exported to USA, UK, Germany, Japan and Australia. The country has exported 19677.89 MT of floriculture products to the world for the worth of Rs. 717.83 Crores in 2023-24. In India, the dry flower industry is predominantly concentrated in Tamil Nadu, West Bengal, Andhra Pradesh and Karnataka. Exporting companies based in Kolkata (West Bengal), Tuticorin (Tamil Nadu), Mumbai (Maharashtra) and Hyderabad (Andhra Pradesh) are generating returns that are 10 to 15 times higher than those from domestic markets (Verma et al., 2012). Dry flower production is labor-intensive providing significant self-employment and job opportunities for a large workforce and fostering the growth of subsidiary industries. While fresh flowers are expensive, short-lived and seasonally available dried flower products are long-lasting and maintain their aesthetic appeal year-round. These dried flowers are often exported as assortments of value-added products. In the Indian floriculture trade the dry flower industry is particularly promising accounting for approximately 70% of the total floriculture market with demand increasing annually by 8-10%.

description: We present the spectroscopic discovery of 69 quasars at 5.8 < z < 7.0, drawn from the Hyper Suprime-Cam (HSC) Subaru Strategic Program (SSP) imaging survey data. This is the 16th publication from the Subaru High-z Exploration of Low-Luminosity Quasars (SHELLQs) project, and completes identification of all but the faintest candidates (i.e., i-band dropouts with zAB < 24 and y-band detections, and z-band dropouts with yAB < 24) with Bayesian quasar probability Pq > 0.1 in the HSC-SSP third public data release (PDR3). The sample reported here also includes three quasars with Pq < 0.1 at z ~ 6.6, which we selected in an effort to completely cover the reddest point sources with simple color cuts. The number of high-z quasars discovered in SHELLQs has now grown to 162, including 23 type-II quasar candidates. This paper also presents identification of seven galaxies at 5.6 < z < 6.7, an [O III] emitter at z = 0.954, and 31 Galactic cool stars and brown dwarfs. High-z quasars and galaxies comprise 75 % and 16 % respectively of all the spectroscopic SHELLQs objects that pass our latest selection algorithm with the PDR3 photometry. That is, a total of 91 % of the objects lie at z > 5.6. This demonstrates that the algorithm has very high efficiency, even though we are probing an unprecedentedly low-luminosity population down to M1450 ~ -21 mag.

description: Laut Weltklimarat IPCC ist die rasche Reduktion der Emissionen von Treibhausgasen in die Atmosphäre die wichtigste Klimaschutzmaßnahme. Da aber die weltweiten Emissionen von CO2 und anderen Treibhausgasen im letzten Jahrzehnt im Mittel immer noch anstiegen, ist es wahrscheinlich, dass das Ziel des Paris-Abkommens »Begrenzung der Erderwärmung auf wesentlich unter 2°C« nicht mehr erreicht wird. Die CO2-Konzentration
 in der Atmosphäre lag Ende 2021 mit 413 millionstel Volumenanteilen um fast 50% über dem Wert vor der Industrialisierung.
 Der Weltklimarat hält daher die Entfernung von CO2 aus der Atmosphäre durch Renaturierung von Feuchtgebieten (Mooren und Auen sowie Mangroven), Aufforstungen, mehr Humus in Böden, beschleunigte Verwitterung von Gesteinen für notwendig, um die »mittlere globale Erwärmung wesentlich unter 2°C« zu halten. Solche und weitere technische Verfahren wie erhöhte Rückstreuung von Sonnenenergie oder erhöhte
 Durchlässigkeit der Eiswolken für Wärmestrahlung werden oft auch Climate Engineering genannt.
Quantum state transfer on the complete bipartite graph

description: Previously it was shown that (almost) perfect state transfer can be achieved on the complete bipartite graph by a discrete-time coined quantum walk based algorithm when both the sender and receiver vertices are in the same partition of the graph and when the sender and receiver are in opposite partitions of the same size. By changing the coin operator, we analyze the state transfer problem and we show that it is still possible to achieve state transfer with high fidelity even when the sender and receiver are in different partitions with different sizes. Moreover, it is also possible to use an active switch approach using lackadaisical quantum walks where the marked vertex is switched between the sender and receiver during the algorithm.

description: We consider a nonminimally coupled curvature-matter gravity theory at the Solar System scale. Both a fifth force of Yukawa type and a further non-Newtonian extra force that arises from the nonminimal coupling are present in the solar interior and in the solar atmosphere up to interplanetary space. The extra force depends on the spatial gradient of space-time curvature R. The conditions under which the effects of such forces can be screened by the chameleon mechanism and be made consistent with Cassini measurement of PPN parameter $γ$ are examined. This consistency analysis requires a specific study of Sun's dynamical contribution to the arising forces at all its layers.

The Acholi People of Northern Uganda: The Forgotten Community
Creators: name: Apwonyokwe, Margaret
Publisher: name: School of Education & Communities, University of East London
Year: 2022

description: This article explores the lived experiences of the Acholi people of northern Uganda who have been exposed to armed conflict, violence, and internal forced displacement into government controlled and self-settled-camps. For three decades the Acholi have been subjected to all forms of human rights violations. The camps began to emerge soon after this current government took power in 1986 and subsequently (Finnström, 2008; Gersony, 1997). The camps are also referred to as “Protected Villages” by the government. As a result of lack of provision for basic needs, up to 1,000 people have been dying on a weekly bases from starvations and preventable diseases in these camps (World Health Organisation, 2005; Dolan, 2009). This article focuses on why the Acholi people have been victimised and examines how the Acholi people have used their collective agency to survive the hardship, the lack of basic provisions, the suffering and neglect that they face on their everyday life in a hostile environment.
D4-branes wrapped on a spindle

description: We construct supersymmetric AdS$_4\timesΣ$ solutions of $D=6$ gauged supergravity, where $Σ$ is a two-dimensional orbifold known as a spindle. These uplift to solutions of massive type IIA supergravity using a general prescription, that we describe. We argue that these solutions correspond to the near-horizon limit of a system of $N_f$ D8-branes, together with $N$ D4-branes wrapped on a spindle, embedded as a holomorphic curve inside a Calabi-Yau three-fold. The dual field theories are $d=3$, ${\cal N }= 2$ SCFTs that arise from a twisted compactification of the $d=5$, ${\cal N}=1$ $USp(2N)$ gauge theory. We show that the holographic free energy associated to these solutions is reproduced by extremizing an off-shell free energy, that we conjecture to arise in the large $N$ limit of the localized partition function of the $d=5$ theories on $S^3\timesΣ$. We formulate a universal proposal for a class of off-shell free energies, whose extremization reproduces all previous results for branes wrapped on spindles, as well as on genus $\mathrm{g}$ Riemann surfaces $Σ_{\mathrm{g}}$. We further illustrate this proposal discussing D4-branes wrapped on $Σ\timesΣ_{\mathrm{g}}$, for which we present a supersymmetric AdS$_2\timesΣ\timesΣ_{\mathrm{g}}$ solution of $D=6$ gauged supergravity along with the associated entropy function.

description: Walter Glaesser (Gläßer) committed his 65th birthday at 07th of March 2009. He was professor in Hydrogeology at the University of Leipzig (since 1994) and Head of Department of Hydrogeology I in the Centre for Environmental Research Leipzig-Halle (1993 –2002) and scientific member of the Department Hydrogeology II of Helmholtz-Centre for Environmental Research Leipzig-Halle (2002–2009). Glaesser’s work has focused on investigations of hydrogeochemical processes in lignite and coppershale mining areas, in the long time pollution of groundwater in different depth in several industrial regions and in-situ groundwater regeneration. The system-analytical work covers chemical and isotopical analyses and the microbiological influence of groundwater on velocity of reactions in nature and in simulation labs. The results will be integrated in hydraulic and reaction models as help in other regions of the world. His results of investigations of the Department of Hydrogeology were documented in national and international journals, in book chapters and proceedings. Glaesser was reviewer for some international and national science journals. He consults in environmental questions by the German BMBF (Ministry of Research, Education and Sciences), UBA (Ministry of Environment) and federal Ministries of Environment in questions of mining and military damages.

description: We identify an infinite class of unbounded potentials for which the Coleman instantons do not exist in D-dimensional spacetime. For such potentials, the decay of a false vacuum is described by the new instantons introduced in [5,6,4]. For each spacetime dimension D, we also construct the two different classes of potentials for which the instanton equations are exactly solvable.

description: Introduction: Adolescents’ sexual and reproductive health (SRH) is strongly influenced by a range of

social, cultural, political, and economic factors and inequalities, which increase adolescents’

vulnerability to SRH risks like unsafe sex, sexual coercion, early pregnancy, and pose barriers to their

access to SRH information and service. In Ethiopia socio cultural taboos, feel ashamed and lack of

communication skill affect adolescent-parent communication on sexual matters. Parents mainly focus

on the negative consequence of sexual intercourse. However there is lack of information regarding

adolescent-parent communication about SRH matters in the study area.

Objective: the main objective of this study is to assess Parent-Adolescents’ Communication on Sexual

and Reproductive Health Matters and associated factors among Secondary and Preparatory students

Methods: Institution based cross-sectional study was conducted. Data was collected from students

aged 15-19 years old. The data was collected by using structured self-administered questionnaire. The

total sample size was 649,calculated by applying single population proportion formulas. Data was

Liberal and Marxist Social Movement Theories: A Structuralist and Critical Realist Approach
Creators: name: Haworth, John
Publisher: name: School of Education & Communities, University of East London
Year: 2022

description: In this article, I respond to the work of Barker and of Nilsen and Cox in their edited volume Marxism and Social Movements on the differences between liberal and Marxist social movement theories and go on to distinguish between what I have called humanist and structuralist Marxist theories. On the differences between liberal and Marxist theories, and while largely agreeing with the authors, I seek to develop a more precise understanding of these differences as their different purposes in explaining and changing the world, by their different views of the roles of social movements under capitalism, by their emphases on ecological, economic and political levels of the social formation, and by their different historical perspectives. On humanist and structuralist Marxist theories, I specifically distance myself from Barker’s infamous statement that structuralist Marxism has “contributed nothing to Marxism as a theory of emancipation” and attempt to explain the contributions of Althusser and of structuralist Marxism to our understandings of the conditions under which people make history. I thus distinguish between humanist and structuralist Marxist theories by their different understandings of the complexities of social formations, by their different views of the importance of human agencies, by their different understandings of organic crises, by their different views of social stabilities and of the frequency of revolutions and by their different views of the roles of ideas and of social interactions in bringing about social transformations. I conclude by explaining the consequences of these differences for debates and for deliberative democracies in social movements.
