Seismic Reliability Analysis of Reinforced Concrete Arch Bridges Considering Component Correlation

Buildings
To more effectively account for the correlation between components in the seismic reliability analysis of reinforced concrete arch bridges, this study proposes a system seismic reliability analysis method based on the D-vine Copula function. First, based

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.

RELIABILITY ANALYSIS FOR JACK-UP GEARBOX BASED ON COPULA BAYESIAN NETWORK

Jixie qiangdu, 2018
A reliability analysis method for complicated mechanical system is proposed which is based on Copula Bayesian network. Since the variables in complicated mechanical system are numerous and correlated to each other,the traditional analysis methods are ...

A genetic algorithm simheuristic for solving the stochastic project portfolio selection problem with portfolio reliability constraints

International Transactions in Operational Research, EarlyView.
Abstract In response to the increasing complexity of modern products, dynamic markets, and intensified competition, project‐based organizations are actively seeking methodologies to efficiently manage their expanding project portfolios. This paper analyzes the project portfolio selection problem in uncertain environments. Despite recent advances in the

Situated Attention and Strategic Leadership Interfaces: The Role of CEO Humility and Digital Transformation Urgency for Corporate Venture Capital Investments

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 ...

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 ...

The Effect of Board Leadership Roles and Committee Responsibilities on Governance Effectiveness

Journal of Management Studies, EarlyView.
Abstract Expectations for corporate directors have expanded over time, placing growing demands on their time and attention. Drawing on the cognitive foundations of the attention‐based view (ABV), we theorize that board directors' leadership roles and committee assignments shape their attentional perspective and engagement in ways that can both hinder ...

The Great Temporal Divide: How Top Management Team Temporal Faultlines and Dominant Subgroups Shape Firm Innovativeness in Iran

Journal of Management Studies, EarlyView.
Abstract While executives vary in attention to the past, present, and future, prior work has largely examined these temporal orientations in isolation or at the individual level, which limits insight into how they jointly configure within top management teams (TMTs) and translate into firm behaviours.
