Green product innovation has been recognized as one of the key factors to achieve growth, environmental sustainability, and a better quality of life. Understanding green product innovation as a result of interaction between innovation and sustainability has become a strategic priority for theory and practice. This article investigates green product innovation by means of a multiple case study analysis of 12 small to medium size manufacturing companies based in Italy and Canada. First, we propose a conceptual framework that presents three (...) key environmental dimensions of green product innovation such as energy minimization, materials reduction, and pollution prevention as identified in the life cycle phases of products. Based on insights gained from in-depth interviews, we discuss firms' motivations to develop green products, environmental policies and targets for products, different dimensions of green product innovation, and challenges faced during developing and marketing of green products. Results from the study are then synthesized and integrated in a toolbox that sheds light on various aspects of green product innovation and provides solutions to challenges and risks that are faced by firms. Finally, implications for managers, academia and public policy makers are discussed. (shrink)

The use of upper limb vibration during exercise and rehabilitation continues to gain popularity as a modality to improve function and performance. Currently, a lack of knowledge of the pathways being altered during ULV limits its effective implementation. Therefore, the aim of this study was to investigate whether indirect ULV modulates transmission along spinal and corticospinal pathways that control the human forearm. All measures were assessed under CONTROL and ULV conditions while participants maintained a small contraction of the right flexor (...) carpi radialis muscle. To assess spinal pathways, Hoffmann reflexes elicited by stimulation of the median nerve were recorded from FCR with motor response amplitudes matched between conditions. An H-reflex conditioning paradigm was also used to assess changes in presynaptic inhibition by stimulating the superficial radial nerve 37 ms prior to median nerve stimulation. Cutaneous reflexes in FCR elicited by stimulation of the SR nerve at the wrist were also recorded. To assess corticospinal pathways, motor evoked potentials elicited by transcranial magnetic stimulation of the contralateral motor cortex were recorded from the right FCR and biceps brachii. ULV significantly reduced H-reflex amplitude by 15.7% for both conditioned and unconditioned reflexes. Therefore, ULV inhibits cutaneous and H-reflex transmission without influencing corticospinal excitability of the forearm flexors suggesting increased presynaptic inhibition of afferent transmission as a likely mechanism. A general increase in inhibition of spinal pathways with ULV may have important implications for improving rehabilitation for individuals with spasticity. (shrink)
