Learning gains from work placements: Innovative behavior and the role of emotional competencies

European Management Review, EarlyView.
Abstract The importance of innovative behavior (IB) has been well documented, and the engagement of employees in IB has become a tacit norm in many organizations. It has also been understood that IB is emotionally charged. However, little research has concentrated on whether higher education (HE) providers can foster IB in university students, and ...

Probabilistic Load Flow Calculation for Distribution Networks Based on Advanced Source-Load Modeling and Time-Varying D-Vine Copula

Energies
With the large-scale integration of distributed photovoltaic generation (PV) into modern distribution networks, the inherent stochasticity and volatility of renewable energy outputs have imposed non-negligible impacts on the secure and economic operation

The Evolution of Interest‐Rate Models: From the Yield Curve to the Swaption Cube

Journal of Economic Surveys, EarlyView.
ABSTRACT Interest‐rate modelling is often taught as a catalogue of competing stochastic equations, obscuring why models were created and why modern sell‐side desks use several simultaneously. This survey reorganises the field around five layers of a pricing architecture: curve construction; arbitrage‐free dynamics; volatility‐smile representation ...

Quasi-copulas as linear combinations of copulas

Fuzzy Sets and Systems
We prove that every quasi-copula can be written as a uniformly converging infinite sum of multiples of copulas. Furthermore, we characterize those quasi-copulas which can be written as a finite sum of multiples of copulas, i.e., that are a linear combination of two copulas.

Acquirer Strategic Orientations, Integration Decisions, and Performance

Journal of Management Studies, EarlyView.
Abstract Integration decisions are not isolated, as they are embedded in an organizational context. Using a multi‐country sample (Nordics, German speaking Europe, and China) of small‐ and medium‐sized acquirers, we explore the influence of firm strategic orientations on how managers conceptualize acquisitions, make integration decisions, and impact ...

QUASI-CONCAVITY PROPERTY OF MULTIVARIATE DISTRIBUTION FUNCTIONS

Ratio Mathematica, 1995
Conditions under which multivariate distribution functions are quasi-concave, are explored. We prove that many elliptically contoured distributions have quasi-concave distribution functions.

Robust CDF‐Filtering of a Location Parameter

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper introduces a novel framework for designing robust filters associated with signal plus noise models having symmetric observation density. The filters are obtained by a recursion where the innovation term is a transform of the cumulative distribution function of the residuals.

Distributionally robust optimal scheduling of integrated energy system considering adaptive Copula function and dynamic reserve

International Journal of Electrical Power & Energy Systems
Deploying an integrated energy system represents a critical pathway to alleviate energy supply pressure and improve energy efficiency. However, in existing works on the integrated energy system, the uncertainties and multi-type reserves over different ...

Models for Temporal Clustering of Extreme Events With Applications to Mid‐Latitude Winter Cyclones

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT The occurrence of extreme events like heavy precipitation or storms at a certain location often shows a clustering behavior and is thus not described well by a Poisson process. We construct a general model for the inter‐exceedance times (IETs) in between extreme events which combines different candidate models for such behavior. One of them is
