Decision-making and coordination in bio-CCUS value chains: Finnish companies, municipalities, and the role of national and EU-level policy

Biogenic carbon capture, utilization, and storage (bio-CCUS) is technically feasible and strategically important for climate policy, yet deployment remains largely pre-commercial. While individual bio-CCUS technologies are increasingly well understood, the actor-level dynamics an...

Fatigue strength improvement of gusset end detail with welding techniques

Abstract Gusset end details are usually welded-around with fillet welds leading to high structural and notch stress concentrations. Under cyclic loads, these structural details are usually prone to fatigue failures. This study investigates an extended welding technique and post-w...

The relationship of autonomy with hybrid worker well-being and productivity - the mediating role of managerial culture

Purpose Knowledge work is extensively location-independent, making flexible work designs more common. However, organizations foster various practices regarding the level of autonomy and control, affecting employee well-being and productivity. To support strategic and operative wo...

A multi-level preprocessing and modelling framework for spectral imaging of microplastics

Spectral imaging provides chemically specific and spatially resolved analysis of microplastics, but its routine application is hindered by large data volumes, acquisition artefacts, spectral variability, and misidentification of polymers due to alike spectra. This study proposes...

Integrated Bibliometric and Computational Analysis of Artificial Intelligence in Sustainable Finance

ABSTRACT The rapid integration of artificial intelligence into financial services presents a transformative opportunity to advance sustainability goals, yet a systematic understanding of its current state and impact is essential. This review aims to synthesize existing literature...

How IT Architecture Flexibility and Governance Decentralization Shape Digital Transformation Capabilities

Modular systems theory and the dynamic capabilities perspective suggest that modularity in the IT function, both architectural and organizational, shapes a firm’s digital transformation capabilities (DTCs), yet the joint effect of these two organizational-design choices has not b...

Advancing Sustainable Competitive Advantage through Green Digital Transformation Leadership, Green Technological Innovation and Green Digital Transformation: An Integrated SEM–NCA Approach

ABSTRACT Environmental sustainability has raised global concerns following the increase in carbon emissions due to industrial and commercial activities. As such, this research aims to examine the association between green digital transformation leadership (GDTL) in Malaysian manu...

Annealed leap-point sampler for multimodal target distributions

Abstract In Bayesian statistics, exploring high-dimensional multimodal posterior distributions poses major challenges for existing MCMC approaches. This paper introduces the annealed leap-point sampler (ALPS), which augments the target distribution state space with modified annea...

B2B influencer marketing collaborations: A relational governance perspective

Influencer marketing has grown rapidly in business markets, yet existing research remains largely rooted in consumer contexts and organization-centric perspectives. Little is known about how B2B influencers perceive collaborations with companies. Addressing this gap, this study c...

Strategic human resource management and resource value attributes for sustainable manufacturing performance

Human capital is increasingly recognized as a strategic driver of sustainable industrial performance, yet empirical evidence on how valuable, rare, inimitable, and non-substitutable (VRIN) human-resource attributes translate into competitive advantage and sustainable performance...

Bridging Collaboration and Sustainability: The Role of Digital Strategy at the Organizational Level

ABSTRACT Supply chain management research indicates that collaborations should be explored from both the demand and supply perspectives. To accomplish this, the present paper investigates the relations among collaborative performance management, digital strategy, and sustainabili...

Objects as Means of Sustainability Knowledge Co-Creation: Working on Value-Laden Issues Across the Research-Practice Boundary

Abstract The negative sustainability impacts of business keep escalating despite the profusion of research-based evidence regarding problems and solution pathways. Sustainability knowledge is complex and value-laden, thus often difficult to act upon. Co-creation between researche...

Convergence Analysis of a Greedy Algorithm for Conditioning Gaussian Random Variables

Abstract In the context of Gaussian conditioning, greedy algorithms iteratively select the most informative measurements, given an observed Gaussian random variable. However, the convergence analysis for conditioning Gaussian random variables remains an open problem. We address t...

Accelerating the market diffusion of bio-based innovations – Evidence from expert and business perspectives and policy strategies

Several policy strategies aim to promote the transition to a bioeconomy as a means to addressing the environmental issues of the prevailing mode of unsustainable production and consumption. Bio-based products, such as wood-based textile fibres and packaging solutions, are promote...

AI-driven Optimization of Urban EV Charging Infrastructure: A Structured Review and Conceptual Framework for Climate-Smart Regions

This presentation was delivered at the Smart Cities in Smart Regions Conference 2026 in Lahti, Finland. It examines how artificial intelligence can support urban EV charging infrastructure planning by translating predictive and optimization models into practical infrastructure de...

A robust kinetic theory-based model for dengue transmission integrating climatic and socio-economic dynamics

Dengue is one of the most critical mosquito-borne viral diseases that has rapidly spread in recent years. Despite the fact that the first dengue vaccine was licensed in 2015, the vaccine is still in the experimental stage. As a result, the primary prevention strategies are vector...

A method for predicting the off-design performance of real gas centrifugal compressors utilising preliminary design data

Being able to predict the centrifugal compressor off-design performance early on in the design process enables designers to match the compressors’ off-design behaviour with the system requirements. For example, they can assess that the compressor is able to produce the required p...

Bayesian quadrature

Bayesian quadrature is a probabilistic, model-based approach to numerical integration, the estimation of intractable integrals, or expectations. Although Bayesian quadrature was popularized already in the 1980s, no systematic and comprehensive treatment has been published. The pu...

The Relationship between Human Values, Job Satisfaction, and Well-being among Thai IT Employees in Thailand: An Exploratory Study
