Dialektyka natury i społeczeństwa przeciwko monizmowi. Esej recenzyjny z „Marx in the Anthropocene” Kohei Saita (2023, Cambridge University Press)
No full textThe article discusses Kohei Saito’s work Marx in the Anthropocene, placing it against the broader background of the discussion of Marx’s ecological thought and explaining the basic assumptions of metabolic scratch theory. The main thread of the book on which the author focuses, however, is Saito’s critique of contemporary ecocritical monist conceptions (binding the orders of nature and culture into a unity). As she shows, Marx’s methodological dualism is better able to identify ways out of the ecological crisis.Artykuł omawia pracę Marx in the Anthropocene Kohei Saita, umieszczając ją na szerszym tle dyskusji nad ekologiczną myślą Marksa oraz wyjaśniając podstawowe założenia teorii rysy metabolicznej. Głównym wątkiem książki, na którym skupia się autorka, jest jednak przeprowadzona przez Saita krytyka współczesnych ekokrytycznych koncepcji monistycznych (wiążących w jedność porządek natury i kultury). Jak pokazuje, metodologiczny dualizm Marksa lepiej pozwala określić drogi wyjścia z ekologicznego kryzysu
Magnetogenesis from a rotating scalar: à la scalar chiral magnetic effect
No full text© 2020, The Author(s). The chiral magnetic effect (CME) is a phenomenon in which an electric current is induced parallel to an external magnetic field in the presence of chiral asymmetry in a fermionic system. In this paper, we show that the electric current induced by the dynamics of a pseudo-scalar field which anomalously couples to electromagnetic fields can be interpreted as closely analogous to the CME. In particular, the velocity of the pseudo-scalar field, which is the phase of a complex scalar, indicates that the system carries a global U(1) number asymmetry as the source of the induced current. We demonstrate that an initial kick to the phase-field velocity and an anomalous coupling between the phase-field and gauge fields are naturally provided, in a set-up such as the Affleck-Dine mechanism. The resulting asymmetry carried by the Affleck-Dine field can give rise to instability in the (electro)magnetic field. Cosmological consequences of this mechanism are also investigated11Nsciescopu
Who Uses Free Trade Agreements?
No full textIt is noted that utilization of ASEAN Free Trade Agreements (FTAs) is low by international standards. In order to clarify the reasons for such low utilization, this paper investigates what kinds of Japanese affiliates in ASEAN are more likely to use FTAs in their exporting, by employing unique affiliate-level data. Our findings are as follows. First, the larger the affiliate is, or the more diversified the origins of its procurements, the more likely it is to utilize an FTA scheme in its exporting. Second, affiliates that export actively to countries with higher general tariffs are more likely to use FTAs. Third, there are clear differences in FTA utilization depending affiliates, locations and sectors.
