Correcting Left‐Truncation Bias in Weibull Reliability Analysis: Synthetic Data Validation for Electrical Utility Assets

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Incomplete historical records in utility asset datasets frequently introduce left‐truncation bias, leading to distorted reliability estimates and suboptimal asset management decisions. This study presents a systematic framework for validating left‐truncation correction in Weibull reliability analysis using synthetic data representative of ...

Entrepreneurial Orientation and Sustainable Enterprise Growth: The Role of Entrepreneurial Agility

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the relationships among entrepreneurial orientation (EO), entrepreneurial agility (EA), and sustainable enterprise growth (SEG) in manufacturing SMEs in Ghana, drawing on Dynamic Capability Theory. A quantitative design was used, with data collected from registered SMEs across key industrial regions via simple random ...

Modeling Multivariate Distributions with Continuous Margins Using the copula R Package

open access: yesJournal of Statistical Software, 2010
The copula-based modeling of multivariate distributions with continuous margins is presented as a succession of rank-based tests: a multivariate test of randomness followed by a test of mutual independence and a series of goodness-of-fit tests.

Severity‐Based Reliability Assessment of Energy Communities

open access: yesSafety Science and Technology, EarlyView.
We develop a severity‐based semi‐Markov framework that replaces binary generation‐demand adequacy with a time‐varying, multistate classification of renewable‐energy shortfalls. The method quantifies shortfall probability, magnitude, persistence, first‐passage time, and unsafe occupation, and derives a cyclo‐stationary severity law to support safety ...

Dynamic stochastic copula models: Estimation, inference and applications [PDF]

open access: yes
We propose a new dynamic copula model where the parameter characterizing dependence follows an autoregressive process. As this model class includes the Gaussian copula with stochastic correlation process, it can be viewed as a generalization of ...

Managing Competency‐Based Resistance in Video‐Mediated L2 Peer Feedback Sessions

open access: yesTESOL Quarterly, EarlyView.
Abstract Though there is growing empirical evidence on managing advice resistance as an institutional work of higher status party with superior epistemic knowledge domain (e.g., trainer) across diverse settings (e.g., supervision meetings), there is still a lack of research on how second language (L2) learners handle peer resistance in real time once ...

Metalinguistic Awareness in the EFL Classroom and Beyond: Exploring the Potential of Translation Tasks

open access: yesTESOL Quarterly, EarlyView.
Abstract Current trends encouraging a move away from monolingual teaching have sparked a renewed interest in the role of translation in language instruction. Yet, there are few theoretically and empirically grounded proposals regarding specific uses of translation in the language classroom.

Pricing bivariate option under GARCH processes with time-varying copula [PDF]

open access: yes
This paper develops a method for pricing bivariate contingent claims under General Autoregressive Conditionally Heteroskedastic (GARCH) process. As the association between the underlying assets may vary over time, the dynamic copula with time-varying ...

What do we mean by ‘consistency’ in weather forecasts?

open access: yesWeather, EarlyView.
Weather forecast users often require forecasts to be ‘consistent’, yet the term is used to describe several different properties of forecast behaviour. This paper proposes a framework distinguishing different forms of consistency in weather forecast products, divided into cross‐product consistency (message, forecast narrative, value‐range and exact ...
