Axiomatization of Boolean Connexive Logics with syncategorematic negation and modalities
Full text linkPreprint artykułuIn the article we investigate three classes of extended Boolean Connexive
Logics. Two of them are extensions of Modal and non-Modal Boolean Connexive Logics with a property of closure under an arbitrary number of negations. The remaining one is an extension of Modal Boolean Connexive Logic with a property of closure under the function of demodalization. In our work we provide a formal presentation of mentioned properties and axiom schemata that allow us to incorporate them into the axiomatic systems. The presented axiom systems are provided with proofs of soundness and completeness. The properties of closure under negation and demodalization are motivated by the syncategorematic
view on the connective of negation and modalities, which is discussed in the
paper.The research conducted in the paper by Tomasz Jarmużek was supported by the OPUS project (UMO-2023/51/B/HS1/02983,

Rejoinder to Block on Indifference
Full text linkArtykuł naukowy zaakceptowany do publikacji w numerze specjalnym Zagadnień Filozoficznych w Nauce (nr 76, 2024 poświęcony filozoficznym podstawom ekonomii)This paper is a rejoinder to Block’s (2022) response to Wysocki’s (2021) essay on Nozick’s challenge levelled at Austrian economics. Instead of merely reiterating Wysocki’s (2021) position, we try to highlight that the Blockean account of indifference and preference presupposes the views which are otherwise unwelcome, given his unyielding commitment to Austrian economics at large. To wit, we argue that Block’s theory still fails to make sense of the law of diminishing marginal utility. Moreover, his extreme idea of choice, sadly, appears to jettison characteristically Austrian subjectivism and thus verges on behaviourism. We conclude that, given all these predicaments the Blockean account is caught in, Block himself (qua Austrian) has a reason to embrace the Hoppean theory of preference and indifference.Narodowe Centrum Nauki, grant numer 2020/39/B/HS5/00610
Agglomeration externalities or network externalities? Explaining productivity in Chinese urban regions
Full text linkThis paper explores the relative importance of agglomeration externalities and network externalities in explaining regional productivity through the lens of a polycentric development framework specific to China. Using enterprise investment data, a spatial econometric model and an instrumental variables strategy, we find that both externalities are important in explaining regional productivity. There are no interaction effects between agglomeration and network externalities, with the latter being more prominent in urban regions with higher levels of polycentricity. Compared to agglomeration externalities, which are geographically confined, network externalities can generate spatial spillovers.This work was supported by Bijzonder Onderzoeksfonds UGent [grant number 01SC0820]; China Scholarship Council [grant number 202006040029]; Research Foundation – Flanders (FWO) [grant number G014119N]; KU Leuven research grant [grant number C14/21/021] and National Science Centre (Poland) funds [grant number 2020/38/A/HS4/00312]
Identification of trait-associated microRNA modules in liver transcriptome of pig fed with PUFAs-enriched supplementary diet
Full text linkDietary lipids provide energy, are cellular structural components, and are involved in physiological processes. Lipids are the dietary source in supplementary diet experiments in pigs. This study aims to investigate the dietary effects of PUFAs on the hepatic transcriptome and physiological pathways of two diets on two pig breeds. Polish Landrace (PL: n = 6) and six PLxDuroc (PLxD: n = 6) pigs were fed with a normal diet (n = 3) or PUFAs-enriched healthy diet (n = 3), and the hepatic miRNA profiles were studied for weighted gene co-expression network analysis biological interactions between gene networks and metabolic pathways of DE miRNA genes. The study identified trait-associated modules that were significantly associated with four phenotypic traits in the dietary groups of PL and PLxD: meat colour (a*), shoulder subcutaneous fat thickness, conductivity 24 h post-mortem (PE24), and ashes. Trait-wise, a large set of co-expressed miRNAs of porcine liver were identified in these trait-associated significant modules (9, 7, 2, and 8) in PL and PLxD. Each module is represented by a module eigengene (ME). Forty-four miRNAs out of 94 miRNAs interacted with 6719 statistically significant target genes with a target score > 90. The GO/pathway analysis showed association with pathways including regulation of metallopeptidase activity, sebaceous gland development, collagen fibril organization, WNT signalling, epithelial tube morphogenesis, etc. The study showed the differences in miRNA expression between the dietary groups of PL and PLxD breeds. Hub genes of discovered miRNA clusters can be considered predicted miRNA genes associated with PE24, meat colour, shoulder subcutaneous fat thickness, and ashes. Discovered target genes for miRNA clusters play significant roles in biological functions such as (i) muscle and body growth development, (ii) different cellular processes and developments, (iii) system development, and (iv) metabolic processes.NCN, 2021/43/I/NZ9/0261
Sustainability, the principle of environmental integration in EU law, and the legal form of planning acts
No full textThis chapter argues that the integrated approach, as an inherent aspect of sustainable transformation of socio-economic life, raises vital theoretical challenges for the contemporary legal system. These can be examined with help of the responsive law paradigm. Presently, public planning at EU level, motivated by environmental goals, is an area that may be used for the purpose of illustrating the trials of ‘greening’ the theory of sources of law. The search of cohesion between policy and law is reflected in the planning act, which is a formal result of law-making activities integrating human development and environmental protection. The chapter attempts to identify and comment on the two key models of planning acts functioning in EU law. Simultaneously, it endeavours to critically assess the state of affairs in that regard after the enactment of the European Green Deal in 2019.UMK w Toruni
Single-particle approach to many-body relaxation dynamics
Full text linkThis study addresses the challenge of modeling relaxation dynamics in quantum many-body systems, specifically focusing on electrons in graphene nanoflakes. While quantum many-body techniques effectively describe dynamics up to a few particles, these approaches become computationally intractable for large systems. Larger systems may be tackled with a single-particle approach that, however, struggles to incorporate relaxation effects. Existing relaxation models encounter issues such as an inability to capture system complexity and violation of the Pauli principle. In this work, we propose a novel single-particle model that accounts for various relaxation effects at the crossroads of quantum optics and solid-state photonics, that overcomes the limitations of previous models. Our approach is rooted in the quantum-optical Lindblad model, where relaxation rates are
deactivated once the target levels saturate due to the Pauli principle. This approach is referred to as the saturated-Lindblad model. To validate the predictions of the saturated-Lindblad model, we confront them against phenomenological and many-body physics models in low-dimensional systems, including atomic chains and graphene nanoflakes. Remarkably, the saturated-Lindblad model exhibits excellent agreement with few-body calculations, distinguishing itself from other existing approaches.
Moreover, by assigning different relaxation rates to different transitions, we successfully reproduce cascade de-excitation dynamics and predict emission spectra. The saturated-Lindblad model offers the ability to describe dynamics in systems of practical sizes, encompassing a wide range of structures that can be effectively captured within the single-particle description.This research was funded by:

Archiwa społeczne: działania w przestrzeni publicznej – oddziaływanie – badania
Full text linkPrezentacja towarzyszyła wystąpieniu wygłoszonemu w trakcie konferencji pt. "Zarządzanie informacją w archiwum, bibliotece i muzeum – stare i nowe wyzwania", Poznań, 16–17 listopada 2023 r.W polskiej praktyce archiwalnej, ale również w nauce przyjęło się na określenie oddolnych inicjatyw dokumentacyjnych używać terminu „archiwum społeczne”, choć bardzo często archiwa te łączą w sobie role, zadania i zbiory właściwe nie tylko dla archiwów, ale również muzeów i bibliotek. Podobnie ich tożsamość, jak i ich działalność, niekoniecznie jest stricte „archiwalna”, a często oscyluje wokół budowania społeczności, animacji kultury, sprawiedliwości społecznej, aktywności obywatelskiej, a także podejścia do źródeł w nurcie postcustodial.
Celem wystąpienia jest przedstawienie rozpoczynającego się w październiku 2023 roku trzyletniego projektu badawczego pt. „Oddziaływanie niezależnych archiwów społecznych”, sponsorowanego przez Narodowe Centrum Nauki.
Referat w szczególności porusza kwestię relacji pomiędzy założeniami i celami archiwów społecznych, a podejmowanymi przez nie działaniami w przestrzeni publicznej, szczególnie w kontekście wyzwań związanych z ich badaniem oraz inspiracji pochodzących z wywiadów z archiwistami społecznymi przeprowadzonych przez autorkę w latach 2015-2018.Narodowe Centrum Nauk
O posłudze liturgicznej diakona stałego
No full textW "Dyrektorium o posłudze i życiu diakonów stałych czytamy", że: „Posługa diakońska została ujęta przez Sobór Watykański II w potrójnym wymiarze «diakonia liturgii, słowa i miłości». W ten sposób wyraża się udział diakona w jedynym i zarazem potrójnym munus Chrystusa w święceniu sakramentalnym” . W dokumencie tym podkreślono bezpośrednie odniesienie do diakonii liturgicznej diakona. Jednocześnie, zauważmy, posługa liturgiczna została wymieniona na miejscu pierwszym. Może to wskazywać na jej ważność w powołaniu diakona stałego.
Nie mamy wątpliwości, że posługa liturgiczna diakonów stałych zajmuje bardzo ważne miejsce w realizacji ich powołania. Można nawet powiedzieć, że to ona w znacznym stopniu czyni diakona i jego powołanie rozpoznawalnymi we wspólnocie Kościoła, a więc w diecezji, parafii czy w mniejszych wspólnotach i grupach pastoralnych. Bardzo często właśnie podczas liturgii daje się on poznać. Tak jest dzisiaj, czy będzie tak zawsze, trudno powiedzieć. Być może w przyszłości albo nawet już dzisiaj, ale tylko w konkretnych przypadkach, akcenty w posłudze i rozpoznawalności diakonów będą rozkładać się inaczej. W niniejszym tekście spróbujemy przyjrzeć się bliżej posłudze liturgicznej diakona w perspektywie zapisów, które spotykamy w "Dyrektorium o posłudze i życiu diakonów stałych"
The cognitive requirements for developing a multimodal communication system: Evidence from experimental semiotics and comparative cognition
Full text linkSpecifying the cognitive requirements for developing a structured, symbolic communication system is crucial when considering what made humans language-ready and enabled them to create language. It is equally important to understand to which extent these requirements are shared with other animals and how they evolved. Experimental semiotics elucidates the processes and necessary requirements for the emergence of a symbolic communication system in interaction. We take an evolutionary perspective to find out what cognitive abilities are essential for successful communication, and to what extent these cognitive abilities are present in animals. By conducting a meta-analysis of existing studies and comparing cognitive abilities across species, we identify common factors like theory of mind and categorical perception and highlight the similarities and differences in these abilities between humans and animals. This innovative approach provides valuable insights into the cognitive underpinnings of symbolic communication system emergence, contributing to our understanding of language evolution.This research is part of the project No. 2021/43/P/HS2/02729 co-funded by the National Science Centre and the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement no.
