Developing a tradition of scholarship : the emergence and evolution of the AHRD-sponsored journals

The Problem Research and theory are the lifeblood of academic disciplines along with the peer-reviewed journals that disseminate such scholarship. Journals become critical repositories that capture the histories and evolution of such disciplines, and their scholarly contributions generate new knowledge that can stimulate further research and improve practice. The Academy of Human Resource Development (AHRD) sponsors four peer-reviewed journals that have contributed to the birth and evolution of the discipline of human resource development (HRD). Yet, little is known about how they came into being, how they have evolved, and what their impact has been within the field of HRD. The Solution This article captures the histories of the emergence and evolution of the four refereed journals sponsored by the AHRD through the unique voices of current and recent past editors of these journals. It then considers common themes of scholarship across the four journals that have helped to shape HRD. The Stakeholders Students, researchers, and scholar-practitioners in the field of HRD and related fields who are interested in learning more about the histories of the journals sponsored by the AHRD, along with their contributions to the scholarship in HRD, will benefit from reading this article

Cobamide extraction procedures for analysis of tissue and microbiome samples

The structure of cobalamin has an upper β- axial ligand group and a lower α-axial ligand base. Different groups can attach to the upper ligand to form different forms of cobalamin. When the lower ligand base is changed, the molecule becomes unusable for humans. These are called the lower ligand analogues and are found most prominently in faecal samples. This study sets out to use a cobamide extraction procedure to identify the types of analogues present in faecal samples. It aims to investigate the effect of supplementation with B12 on the cobamides detected in racehorses' microbiome. Additionally, it aims to identify possible relations between treatment responses and cobamides detected in faecal samples of pernicious anaemia patients. Purification of cobamides is done with a His-tagged cobalamin binding protein and identification of them are done by HPLC-MS. The results show that supplementation does not have an effect on racehorses' cobamides detected and patients who take B12 sublingual spray or tablets have higher amounts of cyanocobalamin in their microbiome. Lastly, this procedure can successfully be adapted to study cobamides in tissue samples

Where does the freshwater go?: Pathways for Greenland and Arctic waters from the east Greenland shelf to the North Atlantic

In the Atlantic, the ocean circulation transports warm and light waters northwards at the surface, and cold and dense waters southwards at depth. This large-scale circulation is called Atlantic Meridional Overturning Circulation (AMOC) and is a key element of the climate system. Increasing fluxes of freshwater from Greenland and the Arctic to the Subpolar North Atlantic (SPNA) could contribute to the weakening of the AMOC in a changing climate by inhibiting deep convection and the formation of deep waters in the Labrador Sea, Irminger Sea and Nordic Seas. However, these fresh waters are first advected over the Greenland continental shelf by narrow western boundary currents. While west of Greenland, both eddies and winds are known to play a role in steering shelf waters into the interior of the Labrador Sea, possible pathways for freshwater into the Irminger and Nordic Seas east of Greenland have been less studied. As recent observations demonstrated the importance of overturning east of Greenland for the AMOC, it is critical to better understand how fresh shelf waters reach these regions. To do so, I used a new observational dataset, composed of 120 surface drifters deployed in five different regions of the east Greenland shelf between 2019 and 2022. Trajectories from these surface drifters show very limited advection of fresh shelf waters into the Irminger Sea and the Nordic Seas. Some areas of the east Greenland shelf are more favourable to export, and eddies and winds can drive local exchanges between the shelf and neighbouring seas. For instance, I show that at the southern tip of Greenland, strong westerly wind events can drive fresh surface waters off-shelf. This new drifter dataset also allowed to investigate the surface circulation over the shelf in areas where observations were so far sparse. The western boundary current that flows along the east Greenland coast is composed of two distinct branches, and I show that the complex shape of the seabed causes these branches to interact. This leads to further constrain of fresh waters towards the coast along the south-east Greenland shelf, and to a spreading of fresh coastal waters towards the edge of the continental shelf at the southern tip of Greenland. The small scale of the east Greenland shelf is a major challenge for the ability of climate models to correctly represent the circulation of fresh shelf waters and where they exit the shelf. Using the HadGEM3 climate models at different resolution, I show that while the one-degree resolution model is unable to represent the circulation around Greenland, increasing the resolution to 0.25 and 0.12 degrees is not sufficient to properly represent cross-shelf exchanges, even though it allows for a better representation of the circulation. This misrepresentation can lead to under or overestimation of freshwater export into the interior seas of the SPNA. Further observational and modelling studies are necessary to understand exchanges between the north-east Greenland shelf and the Nordic Seas, the role of sea ice, and to quantify the input of freshwater to deep convection regions.
