title: Neuroanatomy of a sex changing fish: the New Zealand spotty wrasse (Notolabrus celidotus) brain atlas

authors: Kamstra, Kaj

abstract: For most vertebrates, sexual fate is genetically determined and remains fixed throughout life. However, for some teleost fishes sex is more plastic. Significant progress has been made in characterising the cellular and molecular processes that underpin gonadal sex
change. The brain-mediated mechanisms that underlie and initiate this transformation, however, remain poorly understood. One reason for this is the current lack of a neuroanatomical reference work for sex changing fishes. Here, we present a brain atlas for the New
Zealand (NZ) spotty wrasse (Notolabrus celidotus), developed from 10 wild caught specimens (2 male and 8 female). From each fish, coronal cryosections were collected and stained with cresyl violet solution. Photomicrographs were taken of each section using an
inverted bright field microscope and 3D reconstructions were rendered of each brain for annotation and volumetric comparison of specific brain regions. The brain atlas describes the general features of the NZ spotty wrasse brain as well as its specificities. This atlas
provides the necessary foundation for further investigation of the brain mechanisms driving protogyny in this species.

title: Arcs of supply chain integration

authors: Childerhouse, Paul

subjects: supply chain integration

abstract: Integration is posited by many authors as a supply chain utopia. Indeed, it is claimed as being synonymous with supply chain management excellence. The primary aim of this research is to verify the link between supply chain integration and competitive performance. Detailed information collected via an 8-year international field study of 50 products and their associated supply chains subjected to an extensive statistical analysis provides rigorous insight into supply chain integration in practice. The breadth of supply chain integration significantly correlates with increased performance, yet in practice, the majority of supply chains are not well integrated. However, most supply chains seem to follow a popular route when seeking to enable seamless operations. This starts with enhanced internal effectiveness followed by upstream streamlining and then finally downstream integration. If practitioners are still struggling with supply chain integration, this research confirms that they are not unique in their predicament. Indifferent practice is indeed the norm. Fortunately, practitioners can follow the popular route established herein when seeking to improve integrative capability.

title: Changing genes: Science and being Maori

authors: Hudson, Maui

subjects: ethics

abstract: This commentary follows tangential lines of reason stimulated by Hook‟s thought- provoking paper, “Warrior genes” and the disease of being Māori (2009), to question the ethical responsibilities of scientists to the public in modern society.
