Last few years have seen a huge increase of publications at the intersection of project management and sustainability. Nevertheless, this field has become increasingly fragmented undermining a steady and consistent development. Aiming at balancing tensions between authors' attempts for more 'integration' and the trajectories toward 'fragmentation, we employed an extensive, systematic literature review of 770 publications from the period 1993 to 2017. Therefore, this review offers guidance to scholars less familiar with this concept who encounter SPM in their research.We suggest that the SPM literature can be understood by answering the following questions:(1) Why adopt sustainable business practices into projects? (2) What is the impact of sustainability on traditional project management practices? And (3) how is sustainability embedded in project practices?The three narrative themes illustrate the diverse views on the different aspects of SPM, allowing divergences, such as different philosophical underpinnings or levels of analysis, to flourish without eroding the clarity of the field.

We report optical observations of a number of main-chain thermotropic liquid-crystal polymers. In situ measurements were carried out at elevated temperatures using an apparatus that is capable of providing a controlled translational oscillatory shearing motion to samples of typically 1-10 pm thickness. In static samples we observe either a general birefringence with local scattering from line defects which we believe to be disclinations, or in thicker samples a texture dominated by light scattering due to the presence of dense disclinations. Superimposed shearing appears to result in both the multiplication of disclinations and the progressive decrease in the distance between individual disclinations. At high shear rates 149
