Organizational agility and relational trust: Unraveling the dynamics of pioneering orientation
European Management Review, EarlyView.Abstract In a context of rapidly evolving business landscapes, this study delves into the intricate factors shaping pioneering orientation, focusing particularly on organizational agility in operational and market dimensions. The research, conducted with 302 companies in Peru's World Heritage Cities, utilizes structural equation modeling to analyze ...

Electronic Journal of StatisticsWhen modeling multivariate phenomena, properly capturing the joint extremal behavior is often one of the many concerns. Archimax copulas appear as successful candidates in case of asymptotic dependence. In this paper, the class of Archimax copulas is extended via their stochastic representation to a clustered construction.

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 ...

Bayesian inference for bivariate ranks
, 2018 A recommender system based on ranks is proposed, where an expert's ranking of a set of objects and a user's ranking of a subset of those objects are combined to make a prediction of the user's ranking of all objects.

Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape
European Financial Management, EarlyView.ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...

Median and quantile conditional copulas
Dependence ModelingThis article studies the conditional dependency between random variables, conditionally upon a covariate (vector). The conditional copula fully characterizes this conditional dependency.

Grammar Searches for Wh‐Questions in Beginning‐Level Child Second Language Learners
International Journal of Applied Linguistics, EarlyView.ABSTRACT It is important for learners to be able to ask wh‐questions in interaction. However, making wh‐questions can be difficult for beginning‐level EFL leaners, particularly for those learners whose L1 and L2 differ in the way wh‐questions are formed.

Properties of Hierarchical Archimedean Copulas [PDF]
In this paper we analyse the properties of hierarchical Archimedean copulas. This class is a generalisation of the Archimedean copulas and allows for general non-exchangeable dependency structures. We show that the structure of the copula can be uniquely

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.

Convergence of Archimedean Copulas [PDF]
Convergence of a sequence of bivariate Archimedean copulas to another Archimedean copula or to the comonotone copula is shown to be equivalent with convergence of the corresponding sequence of Kendall distribution functions.No extra differentiability ...
