This paper reviews the second challenge on spectral reconstruction from RGB images, i.e., the recovery of wholescene hyperspectral (HS) information from a 3-channel RGB image. As in the previous challenge, two tracks were provided: (i) a "Clean" track where HS images are estimated from noise-free RGBs, the RGB images are themselves calculated numerically using the ground-truth HS images and supplied spectral sensitivity functions (ii) a "Real World" track, simulating capture by an uncalibrated and unknown camera, where the HS images are recovered from noisy JPEG-compressed RGB images. A new, larger-than-ever, natural hyperspectral image data set is presented, containing a total of 510 HS images. The Clean and Real World tracks had 103 and 78 registered participants respectively, with 14 teams competing in the final testing phase. A description of the proposed methods, alongside their challenge scores and an extensive evaluation of top performing methods is also provided. They gauge the state-of-the-art in spectral reconstruction from an RGB image. arXiv:2005.03412v1 [eess.IV] 7 May 2020

The organizational flexibility finds a substantial place in the literature; however, limited evidence of its institutionalization by managers is noticed. This paper analyzes the managerial paradox toward flexibility in managing business complexity, uncertainty handling, organizational reorientation, and structuring decisions across organizational functions. Thematic analysis is used to investigate the managerial flexibility paradox. The literature is identified in three categories related to workplace, frameworks or concepts, and business environment. It further shows two kinds of orientations: the first one deals with concerns in the implementation of flexibility, and the second showcases the concomitant benefits or performance. The literature related to concerns deals with uncertainty and risk management, while the performancerelated literature deals with the augmentation of flexibility theories. The practicing manager seeks advice in the literature to implement the concepts of flexibility and finds its limited availability. This is the prime reason for the emergence of managerial paradox. This paper recommends that future contributions should emphasize the guidelines for flexibility adoption while expounding the flexibility theories. The findings presented in this paper can potentially draw the attention of academicians and practitioners to devise the ways to implement and enhance organizational flexibility.
