European Journal of Personality, EarlyView., 2020 Abstract Vocational interests are traditionally conceived as stable preferences for different activities. However, recent theorizing suggests their intraindividual variability. This preregistered experience sampling study examined intraindividual variation in selected vocational interests states and related situation and person factors (N = 237 ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines whether ESG‐related profitability differences arise from observable firm characteristics or from structural differences in how firms convert those characteristics into performance outcomes. Using an unbalanced panel data design, the final sample comprises 727 firm‐year observations from 178 publicly listed non‐financial ...

How Organizations Evaluate Eco‐Innovation Investability: A Managerial Cognition Perspective
Business Strategy and the Environment, EarlyView.ABSTRACT Eco‐innovation is widely recognized as a key mechanism through which firms pursue sustainability objectives. However, little is known about the microfoundations through which specific eco‐innovation initiatives secure internal investment support within organizations. Drawing on managerial cognition theory, this study examines how organizations

Compressed sensing MRI with Walsh transform-based sparsity basis
, 2013 The choice of sparsity bases plays a crucial role to reconstruct high-quality MR images from heavily under-sampled k-space signals. Traditionally, the Wavelet transform and the Total Variation (TV) are used as the sparsity bases.

Matrix Factorization and Some Fast Discrete Transforms
AxiomsIn this paper, three discrete transforms related to vector spaces over finite fields are studied. For our purposes, and according to the properties of the finite fields, the most suitable transforms are as follows: for binary fields, this is the Walsh ...

From Sustainable Practices to SME Resilience: An Integrative, Systems‐Based Review With Propositions
Business Strategy and the Environment, EarlyView.ABSTRACT This integrative review examines how sustainable practices foster organizational resilience in small‐ and medium‐sized enterprises (SMEs), supporting long‐term sustainable development. Existing resilience models often overlook SMEs' distinctive challenges—limited resources and managerial short‐termism—whereas research linking day‐to‐day ...

Characterizations of o-polynomials by the Walsh transform
CoRR, 2017 The notion of o-polynomial comes from finite projective geometry. In 2011 and later, it has been shown that those objects play an important role in symmetric cryptography and coding theory to design bent Boolean functions, bent vectorial Boolean functions, semi-bent functions and to construct good linear codes.

Business Strategy and the Environment, EarlyView.ABSTRACTThis study examines whether and under what conditions Environmental, Social, and Governance (ESG) performance becomes financially meaningful in mature capital markets. Using a longitudinal transatlantic panel of large firms listed in the EURO STOXX 50 and S&P 100 over the period 2015–2024, we analyse the within‐firm association between lagged ...

A Characterization of Generalized Boolean Functions Employed in CDMA Communications [PDF]
International Journal of Mathematical, Engineering and Management SciencesIn design of secure cryptosystems and CDMA communications, the negabent functions play a significant role. The generalized Boolean functions have been extensively studied by Schmidt and established several important results in this setup.
