    Redundancy with dignity – Give it to me straight
    (ER Publishing Ltd, 2023-09-01) Macpherson W; Ashwell D
    In times of crisis, organisations implement cost-cutting measures, including retrenchment. Research on employee redundancy often focuses on the processes performed by organisations. This paper, however, reports on the expectations of New Zealand and Australian employees (n=613) during the later stages of the pandemic-lockdown environment, circa late 2021, regarding their organisation’s messaging of imminent redundancy. Employees in both countries indicated that they seek dignity and directness, and to be told face-to-face by their immediate line manager, senior line manager, or CEO that they are being “made redundant”. Interestingly, being told by Human Resources personnel was a least favoured option. This research informs organisations of their organisational justice and corporate social responsibilities in times of retrenchment.

    Point trajectory planning of flexible redundant robot manipulators using genetic algorithms
    (Cambridge, 2002) Yue, Shigang; Henrich, Dominik; Xu, W. L.; Tso, S. K.
    The paper focuses on the problem of point-to-point trajectory planning for flexible redundant robot manipulators (FRM) in joint space. Compared with irredundant flexible manipulators, a FRM possesses additional possibilities during point-to-point trajectory planning due to its kinematics redundancy. A trajectory planning method to minimize vibration and/or executing time of a point-to-point motion is presented for FRMs based on Genetic Algorithms (GAs). Kinematics redundancy is integrated into the presented method as planning variables. Quadrinomial and quintic polynomial are used to describe the segments that connect the initial, intermediate, and final points in joint space. The trajectory planning of FRM is formulated as a problem of optimization with constraints. A planar FRM with three flexible links is used in simulation. Case studies show that the method is applicable.
