Summary: This study adopts the TOE framework to evaluate the impact of business analytics (BA) capabilities on firm performance and addresses the mediating role of innovation capabilities. The results show that organizational factors have a significant impact on firm performance, while IT infrastructure and information quality have no significant and positive effect. Moreover, the findings reveal that innovation capabilities positively mediate the link between IT infrastructure and information quality and firm performance.

Summary: The study presents a general computational method for constructing maps between different cell fates and parametric conditions by systematic perturbations. The method does not require accurate parameter measurements or bifurcations. The maps obtained can help in understanding how systematic perturbations drive cell fate decisions and transitions, providing valuable information for predicting and controlling cell states.

Summary: In this article, the relationship between partial least squares (PLS) and other regularized regression algorithms such as Lasso and ridge regression is explored. A steepest descent alternative to the PLS algorithm is also considered. The emphasis is placed on PLS latent variable analysis and its connections to conjugate gradient, Krylov space, and matrix pseudo-inverse using existing literature. Comparison of PLS with Lasso and ridge regression is conducted in terms of different resolutions along the regularization paths, providing insights into why PLS may not always outperform the other algorithms. A steepest descent PLS is proposed as a regularized regression alternative and evaluated against other algorithms through simulations and an industrial case study.

Summary: Through analyzing a large number of milk samples, the study found that Bayesian regression methods outperformed partial least squares in predicting milk fatty acids, and identified spectral regions associated with fatty acids as well as the impact of carbon number and unsaturation level on the strength of associations.

Summary: The genomic selection methodology has revolutionized plant breeding by using statistical machine learning algorithms to predict candidate individuals. However, it faces challenges when predicting future seasons or new environments. This study compared the performance of the multi-trait partial least square (MT-PLS) regression method with the Bayesian Multi-trait Genomic Best Linear Unbiased Predictor (MT-GBLUP) method and found that MT-PLS outperforms MT-GBLUP in predicting future seasons or new environments.

Summary: This paper proposes a robust method for PLS based on the idea of least trimmed squares (LTS), which effectively deals with high-dimensional regressors. By formulating the LTS problem as a concave maximization problem, the complexity of solving LTS is simplified. The results from simulation and real data sets demonstrate the effectiveness and robustness of the proposed approach.

Summary: This study conducts empirical research on knowledge-hiding behavior in organizations and provides a research framework for the process of hiding knowledge. It finds that knowledge hiding is influenced by exploitative leadership and psychological distress, and verifies the moderating and mediating effects of leader incivility.

Summary: The quantification of soil organic matter (SOM) has been increasing in the Brazilian Cerrado region, where SOM content tends to be low. This study evaluated the performance of a local spectral model for SOM prediction using spectroradiometry. The results showed that recalibration of the local models improved the prediction accuracy, but further research is needed to improve the identification of SOM spatial variability.

Summary: This study uses a near-infrared diffuse reflectance spectroscopy system to accurately determine the soluble solids content of citrus without causing damage. The results show that the NIRDRS light can penetrate the thick peel to some extent, and the selection of specific characteristic variables can improve the accuracy of the quantitative analysis models with fewer variables.

Summary: This paper proposes an accurate quality prediction method for batch processes by considering the slow time-varying characteristics. By constructing sliding windows and batch augmentation matrix, the process data of previous batches are incorporated into the regression model, leading to accurate predictions. Experimental results show that the proposed method outperforms traditional quality prediction methods.

Summary: The study examined optimal preprocessing techniques for MIR spectra of wines and grape berry homogenates, testing their ability to model sensory properties of Cabernet Sauvignon and Chardonnay wines. Results showed SG transformations significantly influenced R-2, while EMSC did not. Predicting wine sensory attributes consistently across vintages remains challenging regardless of the predictors used.
