When Does Top Management Team Diversity Matter in Large Organizations?

Journal of Organizational Behavior, EarlyView.
ABSTRACT Top management teams (TMTs) drive strategic leadership, but there is little clarity on when the composition of these upper echelons most impacts organization performance. Drawing from the categorization‐elaboration model, we study an 18‐year sample of approximately 4500 organizations and over 32 000 executives and find a positive relationship ...

Fractional Moment Theory for Anomalous Transport: A Unified Framework for Lévy Flights, Fractals, and Complex Dynamical Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We develop a unified mathematical framework extending classical moment theory from discrete integer orders to a continuous spectrum of real orders f>0$$ f>0 $$, providing a systematic statistical characterization of complex systems exhibiting power‐law behavior.

Bridging the Gap Between Socio‐Political and Community Acceptance of Wind Energy: Policy Insights for Sustainable Energy Development

Sustainable Development, EarlyView.
ABSTRACT Wind energy plays an important role in achieving energy transition and sustainable development goals, yet disparities between socio‐political and community acceptance continue to hinder project implementation. Understanding this gap is essential for designing more socially responsive wind energy policies.

Do Training Programmes Improve Awareness of Sustainable Finance?

Accounting &Finance, EarlyView.
ABSTRACT Many initiatives worldwide aim to improve financial knowledge through training programmes at different levels of education. In this context, it is worth highlighting that sustainable finance knowledge should receive attention in line with the global challenges (climate change, social and economic inequalities, etc.) society is facing ...

On a problem of optimal recovery and Kolmogorov type inequalities on an interval

Journal of Approximation Theory, 2015
The author uses the solution of certain extremal problems in order to solve an optimal recovery problem for the \(k\)-th derivative of the function on an interval from the information on the function itself, given in the mean square metric. First, he shows an explicit expression for the error of the optimal recovery and for optimal methods in terms of ...

On an inequality of Kolmogorov type for a second-order difference expression

Journal of Inequalities and Applications, 1999
The authors study formally symmetric second order difference operators \(M\) on the weighted \(\ell ^2\) Hilbert space. They investigate the best constant \(K\) in the inequality \[ \|P_1Mx\|^2 \leq K\|x\|\|P_2M^2x\|, \] for all sequences \(x\) with only finitely many nonzero terms, where \(P_i\) cuts off the first \(i\) coordinates of the sequence.

Relationship Between Self‐Reported Bruxism and Perceived Stress Among Brazilian Health Science Students

European Journal of Dental Education, EarlyView.
ABSTRACT Objectives Investigate the relationship between perceived stress and self‐reported bruxism among health science students, as well as to map the instruments used to assess both variables. Methods A total of 545 students from health science programs at the UNIFAL‐MG participated in this cross‐sectional study, which used the Self‐Reported Bruxism

Remarks, questions and conjectures on Landau-Kolmogorov-type inequalities [PDF]

Mathematical Inequalities & Applications, 2000
For the Landau-Kolmogorov inequality \[ \|f^{(k)}\|_B\leq K(n,k,B) \|f^{(n)}\|_B^{k/n}\|f\|_B^{1-k/n}\tag{1} \] with \(f,f^{(n)}\in B\) it is shown that \(K(n,k,L^p(\mathbb{R}\text{ mod }2\pi))= K(n,k,L^p(\mathbb{R}))\), \(1\leq p\leq\infty\). For functions on \(\mathbb{R}^d\), an analog of the form \[ \|(\partial/\partial \xi)^kf\|_B\leq C(n,k,B ...

Goodness‐of‐Fit Tests for Positive Quadrant Dependence

International Statistical Review, EarlyView.
Summary When two random variables are positive quadrant dependent (PQD), they are more likely to assume small (or large) values simultaneously compared with when the random variables are independent. This dependence structure is of interest in many areas, including finance, actuarial science and engineering.

Kolmogorov type inequalities for hypersingular integrals with homogeneous characteristic

Banach Journal of Mathematical Analysis, 2007
In this paper the authors establish new sharp Kolmogorov type inequalities for hypersingular integrals with homogeneous characteristic of multivariate functions from Hölder spaces. Applications of the results obtained to solve Stechkin's problem on the best approximation of unbounded hypersingular integral operator by unbounded ones on functional ...
