Evidence for adaptive explanations of semelparity in animals
Biological Reviews, EarlyView.ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Land birds on atolls: diversity, origin, and function
Biological Reviews, EarlyView.ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Forking and independence for fragments of Jonsson sets
Қарағанды 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.

Exploring Supply Chain Visibility for Circularity: A Delphi Approach
Business Strategy and the Environment, EarlyView.ABSTRACT Circular supply chains (CSCs) depend on enhanced supply chain visibility (SCV) to track and manage resource flows and thereby enable efficient decision‐making. Despite confronting silo mentalities, fragmented information, technological barriers, resistance to change, and a lack of standardization, data sharing remains crucial for SCV and ...

Some properties of Morly rank over Jonsson sets
Қарағанды университетінің хабаршысы. Математика сериясы, 2016 This article introduced and discussed the concepts of minimal Jonsson sets and respectively strongly minimal Jonsson sets. On this basis, it introduces the concept of the independence of special subsets of existentially closed submodel of the semantic ...

Board Networks and Corporate Carbon Emissions: A Cross‐Country Analysis of Causal Effects
Business Strategy and the Environment, EarlyView.ABSTRACT This study examines whether board networks influence corporate carbon emissions and the strategic pathways through which firms decarbonize. Using a sample of 1952 firms across 48 countries from 2003 to 2020, we employ dynamic stacked regressions that exploit exogenous carbon‐regulation shocks affecting firms connected through shared third ...

Companions of the fragments in the Jonsson enrichment
Қарағанды 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.

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how small and medium‐sized enterprises (SMEs) transition from a symbolic, disclosure‐oriented ESG logic toward a substantive ESG‐oriented performance management system (PMS) grounded in actionable KPIs. Drawing on evidence from the Apuan‐Versilian Stone Industrial District through an interventionist research design, we ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how environmental regulations can drive technological change, drawing on the innovation systems perspective and the strong Porter hypothesis (SPH). The SPH suggests that well‐designed stringent regulations can foster innovation and enhance firm competitiveness, performance, and survival, yet prior research remains largely ...
