Forking and independence for fragments of Jonsson sets

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2018
The concept of independence plays a very important role in Model Theory for classification of a fixed complete theory. In this paper, we study the Jonsson theories, which, generally speaking, are not complete.

Companions of the fragments in the Jonsson enrichment

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2017
In this article we consider the properties of central types for the existentially prime strongly convex Jonsson theories in some extension. This class of theories is a subclass of a broad class of Jonsson theories.

From mainland to islands: the evolution of resistance and tolerance to herbivory in long‐lived oaks

open access: yesOikos, EarlyView.
Island biogeography theory predicts that island plants should exhibit reduced defences compared with their mainland relatives due to relaxed herbivory pressure. However, growing empirical evidence challenges this prediction, revealing substantial variation among systems, plant lineages and defence types.

Model-theoretic properties of J-non-multidimensional theories

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
The issues of utilizing the central type to analyze the theoretical and model properties of the idea of heredity were examined in this research, taking into account both theories and the Jonsson spectrum.

Identifying knowledge barriers to agroforestry adoption and co‐designing solutions to them

open access: yesPeople and Nature, EarlyView.
Abstract Compared to monocultures, agroforestry can promote biodiversity, ecosystem functioning and climate resilience, whilst maintaining or enhancing production and profits. Despite this, uptake in temperate regions remains low. Knowledge gaps amongst land managers are a primary barrier to uptake, but little is known about which aspects of ...

Prescriptive Positivism: Discourse on Sustainable Development Goal Interactions and Perspectives for a Post‐2030 World

open access: yesSustainable Development, EarlyView.
ABSTRACT The Sustainable Development Goals (SDGs) are unlikely to be achieved by 2030, prompting debate about what should follow. Beyond revision, there is a need to critically examine what values and assumptions have shaped how the SDGs are conceptualised and operationalised.
