Algebraic characterizations of various Beth definability properties

, 1999
In this paper it will be shown that the Beth definability property corresponds to surjectiveness of epimorphisms in abstract algebraic logic. This generalizes a result by I. N'emeti (cf. [HMT85, Theorem 5.6.10]).

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

Insect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Linear Abelian Modal Logic

Bulletin of the Section of Logic
A many-valued modal logic, called linear abelian modal logic \(\rm {\mathbf{LK(A)}}\) is introduced as an extension of the abelian modal logic \(\rm \mathbf{K(A)}\). Abelian modal logic \(\rm \mathbf{K(A)}\) is the minimal modal extension of the logic of

Logic, Geometry And Probability Theory [PDF]

, 2013
We discuss the relationship between logic, geometry and probability theory under the light of a novel approach to quantum probabilities which generalizes the method developed by R. T.

Why did Putin invade Ukraine? A theory of degenerate autocracy

American Journal of Political Science, EarlyView.
Abstract Many dictatorships end up with a series of disastrous decisions such as Hitler's attack on the Soviet Union or Saddam Hussein's aggression against Kuwait. Even if a certain policy choice is not ultimately fatal for the regime, such as Mao's Big Leap Forward or the Pol Pot's collectivization drive, they typically involve both a miscalculation ...

Open Ended Systems, Dynamic Bisimulation, and Tile Logic

, 2000
The SOS formats ensuring that bisimilarity is a congruence often fail in the presence of structural axioms on the algebra of states. Dynamic bisimulation, introduced to characterize the coarsest congruence for CCS which is also a (weak) bisimulation ...

Algebraic Quantum Field Theory [PDF]

, 2006
Algebraic quantum field theory provides a general, mathematically precise description of the structure of quantum field theories, and then draws out consequences of this structure by means of various mathematical tools -- the theory of operator algebras,

Some culture is hiding in plain sight in research on child development

British Journal of Developmental Psychology, EarlyView.
Abstract Child development is cultural in nature, yet a divide persists between a (cross‐)cultural developmental science niche alongside a seemingly a‐cultural mainstream. In particular, childhood research relying on convenience sampling in often Western, post‐industrial (i.e., WEIRD) societies rarely ventures into issues of culture and context ...

Social and emotional pathways to shame reduction: An RCT with preservice teachers

British Journal of Educational Psychology, EarlyView.
Abstract Background Shame is an unpleasant, activating emotion that has been shown to undermine learners' motivation and achievement and identity development in mathematics education. Recent studies have implemented positive psychology interventions (PPIs) to reduce preservice teachers' shame in mathematics, with promising quantitative outcomes ...

Welcome to the jangle (fallacy): The case of statistics and mathematics anxieties

British Journal of Educational Psychology, EarlyView.
Abstract Background Statistics‐related anxiety is a common barrier to learning in higher education, particularly for psychology and other non‐specialist students. High prevalence rates are concerning because statistical literacy is integral to academic success, employability and informed citizenship.
