Japanese science and technology studies has historically developed under the influence of Marxism, which generally had a great impact on prewar and postwar Japanese social sciences. However, since the late 1970s, the Marxist tradition was taken over by postmodernism and then neoliberalism. The global immiserization of working class recently brought back Marx and his critique of capital. The Marxist tradition should be revitalized by reviewing neo-Marxist works in the 1960s and 1970s, which rightly made science and technology the subject of (...) criticism for the first time.

Let f ϵ Z [ X, Y ] be irreducible. We give a condition that there are only finitely many integers n ϵ Z such that f is reducible and we give a bound for such integers. We prove a similar result for polynomials with coefficients in polynomial rings. Both results are proved by, so-called, nonstandard arithmetic.

LetKbe an algebraic number field andIKthe ring of algebraic integers inK. *Kand *IKdenote enlargements ofKandIKrespectively. LetxЄ *K–K. In this paper, we are concerned with algebraic extensions ofKwithin *K. For eachxЄ *K–Kand each natural numberd, YKis defined to be the number of algebraic extensions ofKof degreedwithin *K.xЄ *K–Kis called a Hilbertian element ifYK= 0 for alldЄ N,d> 1; in other words,Khas no algebraic extension within *K. In their paper [2], P. C. Gilmore and A. Robinson proved that the existence of a (...) Hilbertian element is equivalent to Hilbert's irreducibility theorem. In a previous paper [9], we gave many Hilbertian elements of nonstandard integers explicitly, for example, for any nonstandard natural numberω, 2ωPωand 2ω are Hilbertian elements in*Q, where pωis theωth prime number.

We prove that PTCN cannot be a model of U12. This implies that there exists a first order sentence of bounded arithmetic which is provable in U12 but does not hold in PTCN.

BackgroundSocial cognitive impairments adversely affect social functioning in patients with schizophrenia. Although pharmacological interventions have been suggested to provide some benefits on social cognition, little information is available on the comparative efficacy of pharmacotherapy. Thus, the aim of this planned systematic review and network meta-analysis is to perform a quantitative comparison of the effects of various psychotropic drugs, including supplements, on social cognition disturbances of schizophrenia.MethodsThe literature search will be carried out using the PubMed, Embase, Cochrane Central Register of Controlled (...) Trials, PsycINFO, ClinicalTrials.gov, and International Clinical Trials Registry Platform databases from inception onward. Randomized controlled trials that examined the efficacy of drugs in social cognitive disturbances will be included, based on the most recent studies and the broader literature than previously searched. This protocol defines a priori the methods that will be used for study selection, data collection, quality assessment, and statistical syntheses.DiscussionThe findings this work are expected to help promote the development of better therapeutics of social cognitive impairments in schizophrenia and related psychiatric conditions.Systematic Review Registration[www.crd.york.ac.uk/prospero], identifier [CRD42021293224].

Neoliberalism advocates for the construction of free markets, which are to be used for solutions to economic and social problems rather than state solutions to those problems. Though Neoliberal reforms in Japan have affected its science and technology, STS literature has not focused on responses to neoliberalism through the lens of a country. Japan has a discrete STS history and Japan makes a good case study to the influence of neoliberalism on STS. In August 2010, at Tokyo’s Social Studies of (...) Science (4S) meetings, there were several sessions on neoliberalism and STS. At these sessions, Kunio Goto, Yasumoto Fujita, Hidetoshi Kihara, Hideto Nakajima, Steve Fuller, David Hess, Francis Remedios presented different responses to neoliberalism and STS. This special issue explores two themes. The first theme is Goto's and Fujita's call for a revitalization of Marxist STS as an alternative to the influence of neoliberalism on STS in Japan. The second theme is Kihara's and Nakajima's call for a revitalization of a critical function of STS in Japan. Hess examines STS as a field and its response to neoliberalism in Europe and Anglophone countries. (shrink)
