title: The Betrayal of Workers. Counterrevolution in the 1980s: the Transitory Class and their Hegemony

description: In dismantling a socialist, non-capitalist mixed economy Hungarian elites were following a clear line of neoliberalism with an almost unconditional West-centrism. In this process intellectuals and expert technocrats played a specific role and the paper argues that they formed a transitory “new class” which could start a large-scale privatization process in the name of “Europe”. This formation in a specific global historical moment can explain how the voices opposing the capitalist transformation and the critical left were silenced already in the 1980s. We can also see the specific circumstances of how and why the new class could establish hegemony through civilizational discourses for a while, and how their later control collapsed. This betrayal of workers by a supposedly socially minded professional and intellectual elite needs further analysis in order to understand how through a historic dialectic logic the later authoritarian/illiberal rule can consolidate its positions so easily at the end of a globalization cycle.

description: The French workers’ strikes of May 1968 reflected traditional working-class demands for less work and more pay. The student movement of the sixties confronted both left and right by advancing a cultural revolution of gender equality, expansion of personal freedoms, and eventually multiculturalism. During the long sixties, antiwork ideologies gained popularity and unprecedented public exposure by attempting to synthesize the New Left’s desire for simultaneous personal and social liberation. Antiwork movements also provoked a powerful counterrevolution that endorsed labor and the work ethic. Nevertheless, in France, Spain, and other Western nations, much of the sixties’ cultural revolution has survived, even if challenged.

description: This article discusses the lasting legacy for the Left today of the October Revolution and of the role played by the Bolshevik party. It argues that the October Revolution was motivated by a widespread popular determination to realize the goals of the February liberal-democratic revolution in the face of the imminent threat of counterrevolution at the hands of political forces allied with the propertied classes. The leadership provided in October by the Bolshevik party, a predominantly workers’ movement, was far from a criminal, ideologically motivated act, as often presented by historians. It provided the workers and peasants with the political leadership that they both needed and desired, and did so in full cognizance of the daunting odds that this new revolution faced.

description: Lenin and Trotsky took a keen interest not only of the qualitative aspects of strike dynamics but also the quantitative aspects to examine the changing levels of consciousness, the organisational capacity of the working class and the overall temporal dynamics of the class struggle. They examined the close connection between the strike weapon and economic fluctuations and the detailed movement from the economic to the political strike in order to gauge the path to revolution. The main purpose of this paper is to provide an overview of the quantitative method used by Lenin and Trotsky’s integration of the quantitative aspects in explaining the qualitative dimensions of strikes and protest.

description: Collisions are crucial in governing particle and energy transport in plasmas confined in a magnetic mirror trap. Modern gyrokinetic codes model transport in magnetic mirrors, but some utilize approximate model collision operators. This study focuses on a Pastukhov-style method of images calculation of particle and energy confinement times using a Lenard-Bernstein model collision operator. Prior work on parallel particle and energy balances used a different Fokker-Planck plasma collision operator. The method must be extended in non-trivial ways to study the Lenard-Bernstein operator. To assess the effectiveness of our approach, we compare our results with a modern finite element solver. Our findings reveal that the particle confinement time scales like $a \exp(a^2)$ using the Lenard-Bernstein operator, in contrast to the more accurate scaling that the Coulomb collision operator would yield $a^2 \exp(a^2)$, where $a^2$ is approximately proportional to the ambipolar potential. We propose that codes solving for collisional losses in magnetic mirrors utilizing the Lenard-Bernstein or Dougherty collision operator scale their collision frequency of any electrostatically confined species. This study illuminates the collision operator's intricate role in the Pastukhov-style method of images calculation of collisional confinement.

description: Cost‐control interventions that target physicians’ clinical discretion are common in healthcare, but evidence on their efficacy is scarce; in particular for “soft” policies when liability is unlikely to be enforced by the regulator. We study the effectiveness of preferred drug policies (minimum prescription quotas of specific “preferred” drugs) in altering physicians practice styles within the high volume drug class of HMG‐CoA‐reductase inhibitors (statins) in the German statutory health insurance system. Using a nationally representative panel of ambulatory care physicians between 2011 and 2014, we exploit the decentralized institutional setting to estimate physician responses to variation in preferred drug policies across regional physician associations over time in a generalized difference‐in‐differences design. Results show that although the cost‐control mechanism increases average policy adherence, this effect is mainly driven by physicians with initially high use rates of preferred drugs. We argue that such misdirection may limit the policy’s usefulness in reducing inappropriate practice variation among healthcare providers.

description: The success of generative AI relies heavily on training on data scraped through extensive crawling of the Internet, a practice that has raised significant copyright, privacy, and ethical concerns. While few measures are designed to resist a resource-rich adversary determined to scrape a site, crawlers can be impacted by a range of existing tools such as robots.txt, NoAI meta tags, and active crawler blocking by reverse proxies.
 In this work, we seek to understand the ability and efficacy of today's networking tools to protect content creators against AI-related crawling. For targeted populations like human artists, do they have the technical knowledge and agency to utilize crawler-blocking tools such as robots.txt, and can such tools be effective? Using large scale measurements and a targeted user study of 203 professional artists, we find strong demand for tools like robots.txt, but significantly constrained by critical hurdles in technical awareness, agency in deploying them, and limited efficacy against unresponsive crawlers. We further test and evaluate network-level crawler blockers provided by reverse proxies. Despite relatively limited deployment today, they offer stronger protections against AI crawlers, but still come with their own set of limitations.

description: Determining the types of superconducting order in quantum materials is a challenge, especially when multiple degrees of freedom, such as bands or orbitals, contribute to the fermiology and when superconductivity competes, intertwines, or coexists with other symmetry-breaking orders. Here, we study the Kagome-lattice superconductor CsV3Sb5, in which multiband superconductivity coexists with a charge order that substantially reduces the compound's space group symmetries. Through a combination of thermodynamic as well as electrical and thermal transport measurements, we uncover two superconducting regimes with distinct transport and thermodynamic characteristics, while finding no evidence for a phase transition separating them. Thermodynamic measurements reveal substantial quasiparticle weight in a high-temperature regime. At lower temperatures, this weight is removed via the formation of a second gap. The two regimes are sharply distinguished by a pronounced enhancement of the upper critical field at low temperatures and by a switch in the anisotropy of the longitudinal thermal conductivity as a function of in-plane magnetic field orientation. We argue that the band with a gap opening at lower temperatures continues to host low-energy quasiparticles, possibly due to a nodal structure of the gap. Taken together, our results present evidence for band-selective superconductivity with remarkable decoupling of the (two) superconducting gaps. The commonly employed multiband scenario, whereby superconductivity emerges in a primary band and is then induced in other bands appears to fail in this unconventional kagome superconductor. Instead, band-selective superconducting pairing is a paradigm that seems to unify seemingly contradicting results in this intensely studied family of materials and beyond.

Year: 2013

description: With a goal of informing the City of Vancouver’s solid waste management strategy, this report explores the best practice options for the separation and processing of clean wood waste from from construction, demolition and renovation activities and the potential end use options for these diverted wood materials. The policy instruments that effectively encourage these actions in jurisdictions similar to Vancouver were also identified. A literature review of academic articles, government documents, and consultant reports informed this research. The recommendations for the City of Vancouver, explored in further detail in the report, are as follows: • Source separation of wood waste is the most effective diversion strategy. By encouraging deconstruction methods over traditional demolition practices, the ease and efficiency of source separation can be improved considerably. • The market for recycled and reused construction and demolition waste products needs to be expanded. Establishing demand for these materials can be accomplished through institutional purchasing and encouraging a diversity of end use applications. • Developing market support infrastructure and expanding the distribution network for reused and recycled building materials is critical for raising their market share. The City’s Deconstruction Hub is a great starting point for expanding the local market capacity for reused and recycled wood building materials.

Environmental engagement : what insights can lower mainland nature organizations provide the Lynn Canyon Ecology Centre with regards to program development and social media outreach?
Creators: name: Tung, Gurtej
Publisher: name: The University of British Columbia
Year: 2013

description: The planet is facing many environmental challenges. One way to address these challenges is through environmental education and engagement. In this report, 6 nature organizations from Greater Vancouver were interviewed in hopes of improving environmental program development and delivery at the Lynn Canyon Ecology Centre (LCEC). Several commonalities emerged from the interviews. First, funding for these organizations comes from multiple sources including governmental and corporate. A lot of this funding is directed at youth development. All organizations focused on providing skills and career development to youth. Second, most of the organizations run their programs in multiple locations. These locations are bound by municipal jurisdictions but, in one case, programs run province wide. Finally, all organizations said that their social media presence was lacking but, nevertheless, social media was cited as a valuable outreach tool. In this vein, it is recommended that the LCEC shift focus to youth and young adult skills/career development. There is grant money available for this, such as a Human Resources and Skills Development Canada (HRSDC) grants. Further, the LCEC should increase its sensitivity to multicultural programming by partnering with local organizations, such as the Green Club (http://www.greenclub.bc.ca/), which routinely conducts tours of Lynn Canyon. Also, it is recommended that the LCEC increase its social media presence. This can be done by pursuing creative engagement techniques such as creating online polls, asking timely questions to spark discussion or conducting a photo contest. Additionally, the LCEC should decentralize their outreach presence throughout the District of North Vancouver. For example, consider bringing elements of LCEC’s youth programs, such as Canyon Quest and Rainforest Biodiversity Study, to nearby high schools. Given the organizations interviewed and literature engaged, this study focuses on broad strokes environmental program development. It provides an overview of ‘best practices’ regarding environmental engagement. In the future, it is recommended that research be dedicated to one of the following topics; multicultural environmental engagement, youth skills/ career development within environmental organizations or social media usage amongst environmental organizations.

description: Imaging spin-wave propagation in magnetic materials in a wide frequency range is crucial for understanding and applying spin-wave dynamics. Recently, nitrogen-vacancy (NV) centers in diamond have attracted attention as sensors capable of quantitatively measuring the amplitude and phase of coherent spin waves. However, the conventional sensing protocol has been limited to detecting spin waves whose frequencies match the resonance frequency of the NV spins. We demonstrate that by utilizing the AC Zeeman effect, it is possible to image spin waves propagating in a yttrium iron garnet (YIG) thin film over a wide frequency range up to a maximum detuning of 567 MHz without changing the external magnetic field. Our results expand the applicability of NV centers for spin-wave sensing and pave the way for quantitative investigations of the dynamics in various magnetic materials, such as metallic ferromagnets and van der Waals magnets.

description: Multiband superconductivity arises when multiple electronic bands contribute to the formation of the superconducting state, allowing distinct pairing interactions and gap structures. Here, we present field- and temperature-dependent data on the vortex lattice structure in 2$H$-NbSe$_2$ as a contribution to the ongoing debate on the nature of the superconductivity in this material. The field-dependent data clearly show that there are two distinct superconducting bands, and the contribution of one of them to the vortex lattice signal is completely suppressed for magnetic fields above $\sim$ 0.8 T, well below $B\mathrm{_{c2}}$. By combining the temperature and field scans, we can deduce that there is a moderate degree of interband coupling. From the observed temperature dependences, we find that at low field and zero temperature, the two gaps in temperature units are 13.1 $\pm$ 0.2 and 6.5 $\pm$ 0.3 K ($Δ_{0}$ = 1.88 and 0.94 $k\mathrm{_{B}} T\mathrm{_{c}} $); the band with the larger gap gives just under two-thirds of the superfluid density. The penetration depth extrapolated to zero field and zero temperature is 160 $\pm$ 2 nm.

description: We introduce VR-Doh, an open-source, hands-on 3D modeling system that enables intuitive creation and manipulation of elastoplastic objects in Virtual Reality (VR). By customizing the Material Point Method (MPM) for real-time simulation of hand-induced large deformations and enhancing 3D Gaussian Splatting for seamless rendering, VR-Doh provides an interactive and immersive 3D modeling experience. Users can naturally sculpt, deform, and edit objects through both contact- and gesture-based hand-object interactions. To achieve real-time performance, our system incorporates localized simulation techniques, particle-level collision handling, and the decoupling of physical and appearance representations, ensuring smooth and responsive interactions. VR-Doh supports both object creation and editing, enabling diverse modeling tasks such as designing food items, characters, and interlocking structures, all resulting in simulation-ready assets. User studies with both novice and experienced participants highlight the system's intuitive design, immersive feedback, and creative potential. Compared to existing geometric modeling tools, VR-Doh offers enhanced accessibility and natural interaction, making it a powerful tool for creative exploration in VR.

description: The nonuniform $\mathbb{Z}_2$ symmetric Kitaev chain, comprising alternating topological and normal regions, hosts localized states known as edge-zero modes (EZMs) at its interfaces. These EZMs can pair to form qubits that are resilient to quantum decoherence, a feature expected to extend to higher symmetric chains, i.e., parafermion chains. However, finite-size effects may impact this ideal picture. Diagnosing these effects requires first a thorough understanding of the low-energy physics where EZMs may emerge. Previous studies have largely focused on uniform chains, with nonuniform cases inferred from these results. While recent work [Narozhny, Sci. Rep. 7, 1447 (2017)] provides an insightful analytical solution for a nonuniform $\mathbb{Z}_2$ chain with two topological regions separated by a normal one, its complexity limits its applicability to chains with more regions or higher symmetries. Here, we present a new approach based on decimating the highest-energy terms, facilitating the scalable analysis of $\mathbb{Z}_n$ chains with any number of regions. We provide analytical results for both $\mathbb{Z}_2$ and$\mathbb{Z}_3$ chains, supported by numerical findings, and identify the critical lengths necessary to preserve well-separated EZMs.

description: A majority of blazars exhibit variable emission across the entire electromagnetic spectrum, observed over various time scales. In particular, discernible periodic patterns are detected in the $γ$-ray light curves of a few blazars, such as PG 1553+113, S5 1044+71, and PKS 0426-380. The presence of trends, flares, and noise complicates periodicity detection, requiring careful analysis to determine whether these patterns arise from emission mechanisms or occur by chance. We employ Singular Spectrum Analysis (SSA) for the first time on data from the Large Area Telescope (LAT) aboard the Fermi Gamma-ray Space Telescope to systematically search for periodicity using 28-day binned light curves. We aim to isolate any potential periodic nature of the emission from trends and noise, reducing uncertainties in revealing periodicity. Additionally, we characterize long-term trends and develop a forecasting algorithm based on SSA to predict future emission behavior. We apply SSA to analyze 494 sources detected by Fermi-LAT, focusing on isolating oscillatory components from trends and noise in their $γ$-ray light curves. We compute the Lomb-Scargle Periodogram for oscillatory components extracted by SSA to determine the most significant periods, assessing their local and global significance. Our analysis identifies 46 blazars as potential candidates for quasi-periodic $γ$-ray emissions, each with a local significance $\geq 2σ$. Notably, 33 exhibit a local significance of $\geq 4σ$ (corresponding to a global significance of $\geq 2.2σ$). Our findings introduce 25 new $γ$-ray candidates, doubling the number of potentially periodic sources. This study provides a foundation for future investigations by identifying promising candidates and their significance in blazar variability.

description: Understanding the properties of excited states of complex molecules is crucial for many chemical and physical processes. Calculating these properties is often significantly more resource-intensive than calculating their ground state counterparts. We present a quantum machine learning model that predicts excited-state properties from the molecular ground state for different geometric configurations. The model comprises a symmetry-invariant quantum neural network and a conventional neural network and is able to provide accurate predictions with only a few training data points. The proposed procedure is fully NISQ compatible. This is achieved by using a quantum circuit that requires a number of parameters linearly proportional to the number of molecular orbitals, along with a parameterized measurement observable, thereby reducing the number of necessary measurements. We benchmark the algorithm on three different molecules with three different system sizes: $H_2$ with four orbitals, LiH with five orbitals, and $H_4$ with six orbitals. For these molecules, we predict the excited state transition energies and transition dipole moments. We show that, in many cases, the procedure is able to outperform various classical models (support vector machines, Gaussian processes, and neural networks) that rely solely on classical features, by up to two orders of magnitude in the test mean squared error.

Our new constraints exclude the parameter space that could potentially explain the observed discrepancy between theoretical predictions and experimental data for the Lam-Tung relation. With these updated limits, we model-independently determine the maximum possible influence that beyond-SM contributions could have on the angular coefficients $A_0$ and $A_2$, which enter the Lam-Tung relation.

description: In this paper, we focus on a class of time-inconsistent stochastic control problems, where the objective function includes the mean and several higher-order central moments of the terminal value of state. To tackle the time-inconsistency, we seek both the closed-loop and the open-loop Nash equilibrium controls as time-consistent solutions. We establish a partial differential equation (PDE) system for deriving a closed-loop Nash equilibrium control, which does not include the equilibrium value function and is different from the extended Hamilton-Jacobi-Bellman (HJB) equations as in Björk et al. (Finance Stoch. 21: 331-360, 2017). We show that our PDE system is equivalent to the extended HJB equations that seems difficult to be solved for our higher-order moment problems. In deriving an open-loop Nash equilibrium control, due to the non-separable higher-order moments in the objective function, we make some moment estimates in addition to the standard perturbation argument for developing a maximum principle. Then, the problem is reduced to solving a flow of forward-backward stochastic differential equations. In particular, we investigate linear controlled dynamics and some objective functions affine in the mean. The closed-loop and the open-loop Nash equilibrium controls are identical, which are independent of the state value, random path and the preference on the odd-order central moments. By sending the highest order of central moments to infinity, we obtain the time-consistent solutions to some control problems whose objective functions include some penalty functions for deviation.

description: This study examines the relationship between the concept of serious leisure and user innovation. We adopted the characteristics of innovative consumers identified by Luthje (2004)-product use experience, information exchange, and new product adoption speed-to analyze their correlation with serious leisure engagement. The analysis utilized consumer behavior survey data from the "Marketing Analysis Contest 2023" sponsored by Nomura Research Institute, examining the relationship between innovative consumer characteristics and the degree of serious leisure (Serious Leisure Inventory and Measure: SLIM). Since the contest data did not directly measure innovative consumer characteristics or serious leisure engagement, we established alternative variables for quantitative analysis. The results showed that the SLIM alternative variable had positive correlations with diverse product experiences and early adoption of new products. However, no clear relationship was found with information exchange among consumers. These findings suggest that serious leisure practice may serve as a potential antecedent to user innovation. The leisure career perspective of the serious leisure concept may capture the motivations of user innovators that Okada and Nishikawa (2019) identified.

description: DL_POLY Quantum 2.1 is introduced here as a highly modular, sustainable, and scalable general-purpose molecular dynamics (MD) simulation software for large-scale long-time MD simulations of condensed phase and interfacial systems with the essential nuclear quantum effects (NQEs) included. The new release improves upon version 2.0 through the introduction of several emerging real-time path integral (PI) methods, including fast centroid molecular dynamics (f-CMD) and fast quasi-CMD (f-QCMD) methods, as well as our recently introduced hybrid CMD (h-CMD) method for the accurate and efficient simulation of vibrational infrared spectra. Several test cases, including liquid bulk water at 300 K and ice Ih at 150 K, are used to showcase the performance of different implemented PI methods in simulating the infrared spectra at both ambient conditions and low temperatures where NQEs become more apparent. Additionally, using different salt-in-water (i.e., dilute) and water-in-salt (i.e., concentrated) lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI) aqueous electrolyte solutions, we demonstrate the applicability of our recently introduced h-CMD method implemented in DL_POLY Quantum 2.1 for the large scale simulation of IR spectra of complex heterogeneous systems. We show that h-CMD can overcome the curvature problem of CMD and the artificial broadening of T-RPMD for the accurate simulation of the vibrational spectra of complex, heterogeneous systems with NQEs included.

description: High-resolution X-ray spectroscopy is an essential tool in X-ray astronomy, enabling detailed studies of celestial objects and their physical and chemical properties. However, comprehensive mapping of high-resolution X-ray spectra for even simple interstellar and circumstellar molecules is still lacking. In this study, we conducted systematic quantum chemical simulations to predict the C1s X-ray absorption spectra of CN$^+$, CN, and CN$^-$. Our findings provide valuable references for both X-ray astronomy and laboratory studies. We assigned the first electronic peak of CN$^+$ and CN to C1s $\rightarrow σ^*$ transitions, while the peak for CN$^-$ corresponds to a C1s $\rightarrow π^*$ transition. We explained that the two-fold degeneracy ($π^*_{xz}$ and $π^*_{yz}$) of the C1s$\rightarrowπ^*$ transitions results in CN$^-$ exhibiting a significantly stronger first absorption compared to the other two systems. We further calculated the vibronic fine structures for these transitions using the quantum wavepacket method based on multiconfigurational-level, anharmonic potential energy curves, revealing distinct energy positions for the 0-0 absorptions at 280.7 eV, 279.6 eV, and 285.8 eV. Each vibronic profile features a prominent 0-0 peak, showing overall similarity but differing intensity ratios of the 0-0 and 0-1 peaks. Notably, introducing a C1s core hole leads to shortened C-N bond lengths and increased vibrational frequencies across all species. These findings enhance our understanding of the electronic structures and X-ray spectra of carbon-nitrogen species, emphasizing the influence of charge state on X-ray absorptions.

description: Over the last decade, the field of programmable self-assembly has seen an explosion in the diversity of crystal lattices that can be synthesized from DNA-coated colloidal nanometer- and micrometer-scale particles. The prevailing wisdom has been that a particular crystal structure can be targeted by designing the DNA-mediated interactions, to enforce binding between specific particle pairs, and the particle diameters, to control the packing of the various species. In this article, we show that other ubiquitous nonspecific interactions can play equally important roles in determining the relative stability of different crystal polymorphs and therefore what crystal structure is most likely to form in an experiment. For a binary mixture of same-sized DNA-coated colloidal micrometer-scale particles, we show how changing the magnitudes of nonspecific steric and van der Waals interactions gives rise to a family of binary body-centered tetragonal crystals, including both cesium-chloride and copper-gold crystals. Simulations using pair potentials that account for these interactions reproduce our experimental observations quantitatively, and a theoretical model reveals how a subtle balance between specific and nonspecific forces determines the equilibrium crystal structure. These results highlight the importance of accounting for nonspecific interactions in the crystal-engineering design process.

description: Das Glück: Es stellt sich leichtfüßig ein und erweist sich als störrisch, wenn es direkt erstrebt wird. Und das gute Leben erscheint intuitiv so einfach zu benennen und ist dann doch vielleicht unmöglich zu bestimmen. Die Frage nach dem Glück als einer subjektiven Empfindung bleibt heutzutage den individuellen Selbstauskünften überlassen, die Frage nach dem guten Leben im Sinne einer objektiv bestimmbaren Lebensform bildet die problematische Domäne der Philosophie. Problematisch war die Frage aber nicht von Beginn an. Im Gegenteil: Für die praktische Philosophie der Antike gibt die Frage nach dem guten Leben den prominenten Gegenstandsbereich der Disziplinen von Ethik und Politik ab. Aber das gilt für die Antike und für uns heute nicht mehr. Aber warum eigentlich?

Maximizing local benefits : natural gas development in Northeast British Columbia
Creators: name: Yang, Sherry
Publisher: name: The University of British Columbia
Year: 2013

description: BC’s natural gas (‘NG’) industry has grown significantly over the past decade and emerged as one of the province’s strategic sectors. Given the key role it plays in BC’s economy, this study builds on the Department of Industry’s (‘Industry Canada’) interest in understanding to what extent communities in Northeast BC (‘NEBC’) are maximizing economic benefits through NG development. The study arrives at the following findings: • Northeast BC’s NG industry drives GDP, high-paying employment opportunities, business development, and revenues for particular municipalities; • Although industries are expanding upstream opportunities outside of the conventional natural gas development value chain, economic benefits are not maximized to the full extent as reflected by employment leakages and weak downstream initiatives; and • NG industry’s social and environmental impacts undermine the industry’s long-term development, community growth and ability to maximize benefits. To help communities optimize NG’s potential, this study recommends: • Support existing initiatives on local skills development to help bridge existing labour supply with industry needs; • Facilitate regional initiatives to bring together NG businesses across the supply chain to network, access resources and showcase industry’s capabilities to NG producers; • Nurture local capacity in value-added activities in NG; • Identify strategies to manage the industry’s social impact and improve liveability in order to support a prosperous and long-term settlement by permanent residents; and • Promote better communication, transparency and accountability of the industry’s environmental conduct.
