    The article is aimed at investigating the current practice of verifying information in non-financial statements of oil and gas sector companies. The study is based on the analysis of the current regulatory framework for confirming “(certification)” of non-financial reporting, which is structured into two blocks: regulatory documents that define the requirements for the disclosure of information in non-financial reporting, applied at the international and national levels, and regulatory documents that define the requirements for the verification of non-financial reporting at the international and national levels. A comparative analysis of the main standards and recommendations used for disclosure of information in ESG reporting is carried out. Regulatory acts containing general requirements for disclosure of information about the activities of PJSC oil and gas complex in the Russian Federation are considered. The systematization of Russian regulations in the field of disclosure of information on sustainable development and ESG factors and structural elements of the annual report is carried out and the characteristics of the main regulations for conducting an independent audit of non-financial reporting are given. In the course of the study, a matrix of categories was developed that ensure the reliability of public reporting. The features of the verification practice of Russian oil and gas companies that are system-forming are considered. An overview of Russian companies disclosing non-financial information in accordance with GRI, SASB, TCFD and CDP standards is presented. Based on the conducted research, it is concluded that the current regulatory framework in the field of confirmation (assurance) of non-financial reporting requires improvement of the terminology and differentiation of the concepts of “verification”, “assurance”, “confirmation”, “audit”, in order to develop the practice of business audit of the XXI century. The study can be useful for managers and decision makers aimed at implementing the Concept of Sustainable Development and achieving Sustainable Development Goals

    Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

    Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all binary black hole events from the third observing run of the LIGO--Virgo network. We search for repeated signals from strong lensing by 1) performing targeted searches for subthreshold signals, 2) calculating the degree of overlap amongst the intrinsic parameters and sky location of pairs of signals, 3) comparing the similarities of the spectrograms amongst pairs of signals, and 4) performing dual-signal Bayesian analysis that takes into account selection effects and astrophysical knowledge. We also search for distortions to the gravitational waveform caused by 1) frequency-independent phase shifts in strongly lensed images, and 2) frequency-dependent modulation of the amplitude and phase due to point masses. None of these searches yields significant evidence for lensing. Finally, we use the non-detection of gravitational-wave lensing to constrain the lensing rate based on the latest merger-rate estimates and the fraction of dark matter composed of compact objects

    Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

    Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≀0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

    Ultralight vector dark matter search using data from the KAGRA O3GK run

    Get PDF
    Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

    In the context of the global financial crisis and pandemic, issues related to risk management are of paramount importance, which requires the creation of an effective risk management system and disclosure of information regarding risks in the reporting of commercial organizations, focused on the information needs of stakeholders. This article is aimed at studying the existing practice of disclosing information regarding risks in the financial and non-financial statements of Russian companies. The study is based on the analysis of the current practice of disclosure of information regarding risks in Russia and abroad. Using the analysis of risk disclosure in 210 Russian commercial organizations, the study was aimed, foremost, at identifying factors influencing the format and quality of risk disclosure in financial and non-financial reporting, and secondly, at summarizing the practices of risk disclosure in integrated reporting in Russian organizations and the benefits of using integrated reporting. In this sense, the article contributes to the existing literature as an innovative study that determines the directions of development of the methodology for disclosing information regarding risks in integrated reporting in order to improve its quality and information content in accordance with the Concept of value Creation by the organization in combination with the Concept of Sustainable Development. For stakeholders, this study emphasizes the fact that, in the context of the risk disclosure format used, the quality of this information depends on a number of factors (organizational, technological, legal, cultural, economic). The study could be useful for managers and decision makers whose aim is to implement the Concept of Sustainable Development and the achievement of Sustainable Development Goals

    International audienceWe present results from a search for X-ray/gamma-ray counterparts of gravitational-wave (GW) candidates from the third observing run (O3) of the LIGO-Virgo-KAGRA (LVK) network using the Swift Burst Alert Telescope (Swift-BAT). The search includes 636 GW candidates received in low latency, 86 of which have been confirmed by the offline analysis and included in the third cumulative Gravitational-Wave Transient Catalogs (GWTC-3). Targeted searches were carried out on the entire GW sample using the maximum--likelihood NITRATES pipeline on the BAT data made available via the GUANO infrastructure. We do not detect any significant electromagnetic emission that is temporally and spatially coincident with any of the GW candidates. We report flux upper limits in the 15-350 keV band as a function of sky position for all the catalog candidates. For GW candidates where the Swift-BAT false alarm rate is less than 10−3^{-3} Hz, we compute the GW--BAT joint false alarm rate. Finally, the derived Swift-BAT upper limits are used to infer constraints on the putative electromagnetic emission associated with binary black hole mergers
