For a free filter F on $$\omega $$ ω, endow the space $$N_F=\omega \cup \{p_F\}$$ N F = ω ∪ { p F }, where $$p_F\not \in \omega $$ p F ∉ ω, with the topology in which every element of $$\omega $$ ω is isolated whereas all open neighborhoods of $$p_F$$ p F are of the form $$A\cup \{p_F\}$$ A ∪ { p F } for $$A\in F$$ A ∈ F. Spaces of the form $$N_F$$ N F constitute the (...) class of the simplest non-discrete Tychonoff spaces. The aim of this paper is to study them in the context of the celebrated Josefson–Nissenzweig theorem from Banach space theory. We prove, e.g., that, for a filter F, the space $$N_F$$ N F carries a sequence $$\langle \mu _n:n\in \omega \rangle $$ ⟨ μ n : n ∈ ω ⟩ of normalized finitely supported signed measures such that $$\mu _n(f)\rightarrow 0$$ μ n ( f ) → 0 for every bounded continuous real-valued function f on $$N_F$$ N F if and only if $$F^*\le _K{\mathcal {Z}}$$ F ∗ ≤ K Z, that is, the dual ideal $$F^*$$ F ∗ is Katětov below the asymptotic density ideal $${\mathcal {Z}}$$ Z. Consequently, we get that if $$F^*\le _K{\mathcal {Z}}$$ F ∗ ≤ K Z, then: (1) if X is a Tychonoff space and $$N_F$$ N F is homeomorphic to a subspace of X, then the space $$C_p^*(X)$$ C p ∗ ( X ) of bounded continuous real-valued functions on X contains a complemented copy of the space $$c_0$$ c 0 endowed with the pointwise topology, (2) if K is a compact Hausdorff space and $$N_F$$ N F is homeomorphic to a subspace of K, then the Banach space C(K) of continuous real-valued functions on K is not a Grothendieck space. The latter result generalizes the well-known fact stating that if a compact Hausdorff space K contains a non-trivial convergent sequence, then the space C(K) is not Grothendieck. (shrink)

Most discussions of the reproducibility crisis focus on its epistemic aspect: the fact that the scientific community fails to follow some norms of scientific investigation, which leads to high rates of irreproducibility via a high rate of false positive findings. The purpose of this paper is to argue that there is a heretofore underappreciated and understudied dimension to the reproducibility crisis in experimental psychology and neuroscience that may prove to be at least as important as the epistemic dimension. This is (...) the communication dimension. The link between communication and reproducibility is immediate: independent investigators would not be able to recreate an experiment whose design or implementation were inadequately described. I exploit evidence of a replicability and reproducibility crisis in computational science, as well as research into quality of reporting to support the claim that a widespread failure to adhere to reporting standards, especially the norm of descriptive completeness, is an important contributing factor in the current reproducibility crisis in experimental psychology and neuroscience.

We argue that Yarkoni's proposed solutions to the generalizability crisis are half-measures because he does not recognize that the crisis arises from investigators' underappreciation of the roles of theory in experimental research. Rather than embracing qualitative analysis, the research community should make an effort to develop better theories and work toward consistently incorporating theoretical results into experimental practice.

Inequality of incomes is one of the significant factors forming the social capital. Two views dominate among economists dealing with the influence of inequality of income on economic growth. On the one hand, a too low inequality of income does not motivate people to increase the labour productivity. A low inequality of income might result from an extended social care system and overloading GDP with social transfers. A good example of it may be a situation when the unemployed refuses to (...) accept a job offer and prefers the unemployment benefit rather to a slightly higher salary. Moreover, a lack of incentives for the employee who fails to acknowledge the economic sense of increasing the productivity of his work might lead to the slower growth of economy. On the other hand, a contrary view suggests that an increase of the inequality of income has a negative impact on the economy. The accumulation of wealth by a small number of citizens raises doubts about good use of that wealth for investments necessary for the growth of the economy. An excessive inequality of income is confronted with disapproval of the significant part of society and regarded as unfair and unjustified. It may also increase the crime level and decrease the trust and, more generally, lead to the weakening of social capital. The arguments above lead to a hypothesis that the influence of the inequality of income on the growth of the economy has a non-linear character. We confirmed this hypothesis in growth models of the US and Swedish economies. We assess the historically optimal inequality of income measured by the Gini coefficient at 46% and 24% for the US and Sweden respectively. The optimal inequality of income in Poland was assessed previously at 29%. The dissimilarities may result from the cultural differences, educational level differences, ethnic differences and differences in diligence. (shrink)

The paper presents two objections against Putnam’s Twin Earth argument, which was intended to secure semantic externalism. I first claim that Putnam’s reasoning rests on two assumptions and then try to show why these assumptions are contentious. The first objection is that, given what we know about science, it is unlikely that there are any natural-kind terms whose extension is codetermined by a small set of microstructures required by Putnam’s indexical account of extension determination. The second objection is that there (...) may not be a plausible concept of a speech community whose adoption would classify Oscar and Twin Oscar as members of different speech communities and, at the same time, render Oscar and Twin Oscar as being in the same psychological state. I contend that Putnam’s argument fails because both objections are justified. (shrink)

There are three intentions (aims) of this paper. First, to focus the attention of readers to three not so well known and least frequently quoted by economists of Mises’s books, namely his 1957 Theory and History: An Interpretation of Social and Economic Evolution, and two closely related The Ultimate Foundation of Economic Science: An Essay on Method (1962), and Epistemological Problems of Economics (1933/1960). The second aim is to outline Mises’s legacy, presented in the form of eleven dimensions of Mises’s (...) Intellectual Universe. The eleven dimensions of Mises’s system are: Economics as science, praxeology, and human action; Methodological dualism; Judgments of value and subjectivism; Individualism; Rationalism and human action; Consumer; Cooperation and competition; Thymology; Mathematics in economics; Predictions; and Historical analysis. Third, to present the main issues related to Mises’s concept of rationalism. There is no mention of Ludwig von Mises’s concept of rationality in a great number of books and papers dealing with the understanding of the rationality of human beings. The concept of rationality proposed by Ludwig von Mises is neglected by modern researchers and economists of different schools, but especially by mainstream economists. A good example of neglecting Mises’s ideas on rationality is the latest book by Nassim Taleb, Skin in the Game: Hidden Asymmetries in Daily Life. Although Taleb’s proposition of understanding rationality and irrationality is very close to the concept of Mises, he does not refer to Mises’s work at all. No single word on Mises in that book!

In recent years, attention has become a matter of increasing public concern. New digital technologies have transformed human attention materially and discursively, reorganizing perceptual practices and inciting debates about them. The essays in this special issue emerged from a set of panels focused on attention at the 4S conference in New Orleans in 2019. They are all, in various ways, concerned with shifts among attention’s many meanings: between payment and care, instinct and agency, or vulnerability and power. Drawing on Science (...) and Technology Studies sensibilities, these pieces examine how scientific and technical actors are invested in theorizing and capturing attention, while simultaneously engendering new forms of care, resistance, and critique. At a moment where the attention economy appears to be in transformative crisis, this collection maps a set of incipient directions that ask us to pay attention to not only attention itself but also to the many sociotechnical settings where experts and publics are shifting attention’s meaning and value.

The perception of separation between school and home/community is related to diminished achievement in school and lack of motivation to learn STEM subjects. The National Council of Educational Research and Training is among many research organisations that have strongly recommended that schools bridge the disconnect between school-based knowledge and learners’ everyday knowledge. We designed the SPIRALS curriculum to bridge this gap between formal science and students’ everyday lives. SPIRALS helps students explore community-based practices to learn about science, environmental sustainability and (...) systems thinking. We implemented the SPIRALS curriculum in a private, urban, English medium school in Western India with approximately 315 students and their four teachers, 214 of whom also participated in the research from which our conclusions are drawn. Our findings about program impacts rely upon analysis of interviews with teachers and students, as well as student work, and conference participation assessment surveys distributed after a capstone experience at which students present their work. This chapter describes our findings about how students learned science, environmental sustainability, and systems thinking through engagement with community-based practices. We also discuss the process of how the SPIRALS approach worked in India and how it could be expanded into a broader learning model across different socio-cultural contexts within India. (shrink)

The essay presents some gnoseological themes with reference to the intellect of the separated soul according to John Duns Scotus. Four questions of the Ordinatio IV, d. 45 deal with these themes. In this concret cognitive situation is possible, according to Doctor Subtilis, to get to know the new quiddities of things, in spite of a lack of the empiric cognition. It means leaving behind the conception of generic empiricism and moving to the recognition of more cognitive abilities, as in (...) Aristoteles’s conception. In a post death state intellect continues to have the memory of the quiddities of things known while still connected with the body and can remember concret things and events known by the senses during earthly life. Such a gnoseological notion evidences the cognitive continuity of the human intellect after death, its incorruptibility and cognitive ability at least as such as one had during earthly life. We can see here the connection of philosophic and theological questions, which mutually condition and penetrate each other. According to Scotus it is possible for the intellect of the separated soul to remember the past and to acquire new cognition. Moreover, it is also possible for such an intellect to know the prayers we refer to the blessed in heaven. Such an intellectual approach evidences a strong Augustinian influence on John Duns Scotus’ epistemic conception. (shrink)
