Family Involvement and Financial Performance: How Do They Affect the Sustainability Commitment of Family Businesses?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The socio‐emotional wealth (SEW) perspective suggests that the specific priorities of a family business may make it more or less inclined to engage in sustainable practices. This paper examines how family business heterogeneity regarding family ownership, financial performance, and family board members affects the sustainability commitment of ...

Diffusion Kurtosis Imaging Based on Adaptive Spherical Integral

open access: yesIEEE Signal Processing Letters, 2011
Diffusion kurtosis imaging (DKI) is a recent approach in medical engineering that has potential value for both neurological diseases and basic neuroscience research. In this letter, we develop a robust method based on adaptive spherical integral that can compute kurtosis based quantities more precisely and efficiently.

Effects of diffusional kurtosis imaging parameters on diffusion quantification [PDF]

open access: yesRadiological Physics and Technology, 2013
Diffusional kurtosis imaging (DKI) is a new technique based on non-Gaussian water diffusion analysis. However, the original DKI protocol (six b values and 30 motion-probing gradient (MPG) directions) requires more than 10 min of scanning time, which is too long for daily clinical use. We aimed to find suitable b value, MPG direction, and diffusion time

Influence of Adaptive Denoising on Diffusion Kurtosis Imaging at 3T and 7T

open access: yesComputer Methods and Programs in Biomedicine, 2023
Choosing the most appropriate denoising method to improve the quality of diagnostic images maximally is key in pre-processing of diffusion MRI images. Recent advancements in acquisition and reconstruction techniques have questioned traditional noise estimation methods favoring adaptive denoising frameworks, circumventing the need to know a priori ...

Prosumers and Sustainable Market Governance: Development of the Community‐Oriented Marketing Approach Scale

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This research develops and empirically validates the Community‐Oriented Marketing Approach (COMA), a 20‐item multidimensional scale designed to measure prosumer perceptions within participatory market systems. COMA conceptualizes prosumers as active co‐value creators and institutional agents, driving sustainable market governance.

Positive definiteness of Diffusion Kurtosis Imaging

open access: yesInverse Problems and Imaging, 2012
Diffusion Kurtosis Imaging (DKI) is a new Magnetic Resonance Imaging (MRI) model to characterize the non-Gaussian diffusion behavior in tissues. In reality, the term $bD_{app}-\frac{1}{6}b^2D_{app}^2K_{app}$ in the extended Stejskal and Tanner equation of DKI should be positive for an appropriate range of $b$-values to make sense physically.

Differentiation of placenta percreta through MRI features and diffusion-weighted magnetic resonance imaging

open access: yesInsights into Imaging, 2023
Objectives To identify whether parameters measured from diffusion kurtosis and intravoxel incoherent motion help diagnose placenta percreta. Methods We retrospectively enrolled 75 patients with PAS disorders including 13 patients with placenta percreta ...

Sustainability Reporting Quality, Ethical Leadership, and Earnings Management: Evidence From an Emerging Economy

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study analyzes the relationship between sustainability reporting quality (SRQ) and earnings management (EM) in an emerging economy and investigates the moderating role of ethical leadership. Analyzing 531 firm‐year observations from mandatory reports (2022–2024), SRQ is measured via a 51‐indicator index, while EM is proxied by the ...
