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.

Copula Based Semiparametric Regressive Models
This paper studies the estimation of copula-based semi parametric stationary Markov models. Described models allow us evaluate the parameters of copula, which has the best fit to previously selected model (simple estimators of the marginal distribution ...

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.

Journal of Management Studies, EarlyView.Abstract Integrating the attention‐based view with the strategic leadership interfaces perspective, we propose a theoretical model of situational urgency mechanisms influencing the allocation of CEOs' attention towards responsive actions. Specifically, we theorize upon the role of humility, which leads CEOs towards embracing interfaces and makes them ...

Ripples in the Pond: Product Portfolio Reconfiguration and Dynamism in the Competitive Environment
Journal of Management Studies, EarlyView.Abstract The management literature often overlooks how firms can alter the competitive landscape without introducing groundbreaking changes or innovations. Applying the awareness, motivation, and capability framework from competitive dynamics, we posit that as a firm intensifies its product portfolio reconfiguration, its rivals become increasingly ...
