    Inclusion in Information Systems (IS) has received significant attention in recent years, but inclusion in IS curriculum design and delivery is comparatively underdeveloped. Understanding and working with diversity in IS student groups has implications for how we prepare students for a diverse workplace and the design and development of IS systems. Although progress has been made towards inclusive higher education, institutions have not transformed into multicultural diverse organizations. This paper showcases an initiative to apply principles of Universal Design in the particular context of an IS postgraduate programme in a leading Irish business school. This initiative is set within the context of two connected research projects seeking to identify barriers to inclusion experienced by students generally, and particularly by certain student groups, in the same school. The findings demonstrate the persistence of inclusion issues in higher education, including in IS, that Universal Design principles are effective in developing more inclusive teaching and learning practices, and that small actions can have a big impact in this regard. A set of key recommendations is provided; while not exhaustive, these contribute to the wider discourse on inclusion and offer practical suggestions to educators on the design and delivery of inclusive programmes at both undergraduate and postgraduate level

    Synaptic Zn2+ potentiates the effects of cocaine on striatal dopamine neurotransmission and behavior

    Cocaine binds to the dopamine (DA) transporter (DAT) to regulate cocaine reward and seeking behavior. Zinc (Zn2+) also binds to the DAT, but the in vivo relevance of this interaction is unknown. We found that Zn2+ concentrations in postmortem brain (caudate) tissue from humans who died of cocaine overdose were significantly lower than in control subjects. Moreover, the level of striatal Zn2+ content in these subjects negatively correlated with plasma levels of benzoylecgonine, a cocaine metabolite indicative of recent use. In mice, repeated cocaine exposure increased synaptic Zn2+ concentrations in the caudate putamen (CPu) and nucleus accumbens (NAc). Cocaine-induced increases in Zn2+ were dependent on the Zn2+ transporter 3 (ZnT3), a neuronal Zn2+ transporter localized to synaptic vesicle membranes, as ZnT3 knockout (KO) mice were insensitive to cocaine-induced increases in striatal Zn2+. ZnT3 KO mice showed significantly lower electrically evoked DA release and greater DA clearance when exposed to cocaine compared to controls. ZnT3 KO mice also displayed significant reductions in cocaine locomotor sensitization, conditioned place preference (CPP), self-administration, and reinstatement compared to control mice and were insensitive to cocaine-induced increases in striatal DAT binding. Finally, dietary Zn2+ deficiency in mice resulted in decreased striatal Zn2+ content, cocaine locomotor sensitization, CPP, and striatal DAT binding. These results indicate that cocaine increases synaptic Zn2+ release and turnover/metabolism in the striatum, and that synaptically released Zn2+ potentiates the effects of cocaine on striatal DA neurotransmission and behavior and is required for cocaine-primed reinstatement. In sum, these findings reveal new insights into cocaine's pharmacological mechanism of action and suggest that Zn2+ may serve as an environmentally derived regulator of DA neurotransmission, cocaine pharmacodynamics, and vulnerability to cocaine use disorders

    Karawhiua the reo : unlease te reo and give it heaps

    Te Whāriki (MoE, 2017) emphasises the importance of weaving te reo Māori and tikanga Māori for all children into the everyday curriculum. Research however continues to reflect significant under-use of te reo Māori within the early childhood education sector by teachers. This session aims to support best practice by drawing upon the findings from our Raranga Reo research project and the newly developed He taonga mō ā tātou mokopuna: The teaching and learning guide. Supporting teachers to reflect on their own challenges, this session focusses on having fun, building courage to include te reo Māori naturally in a range of areas of their practice. The aim of this session is to support a shift from the mandatory use of te reo Māori, to practice that is truly authentic recognising te reo Māori as a living and relevant language

    Coimmobilization of Acetylcholinesterase and Choline Oxidase on Gold Nanoparticles: Stoichiometry, Activity, and Reaction Efficiency

    Hybrid structures constructed from biomolecules and nanomaterials have been used in catalysis and bioanalytical applications. In the design of many chemically selective biosensors, enzymes conjugated to nanoparticles or carbon nanotubes have been used in functionalization of the sensor surface for enhancement of the biosensor functionality and sensitivity. The conditions for the enzyme:nanomaterial conjugation should be optimized to retain maximal enzyme activity, and biosensor effectiveness. This is important as the tertiary structure of the enzyme is often altered when immobilized and can significantly alter the enzyme catalytic activity. Here we show that characterization of a two-enzyme:gold nanoparticle (AuNP) conjugate stoichiometry and activity can be used to gauge the effectiveness of acetylcholine detection by acetylcholine esterase (AChE) and choline oxidase (ChO). This was done by using an analytical approach to quantify the number of enzymes bound per AuNP and monitor the retained enzyme activity after the enzyme:AuNP synthesis. We found that the amount of immobilized enzymes differs from what would be expected from bulk solution chemistry. This analysis was further used to determine the optimal ratio of AChE:ChO added at synthesis to achieve optimum sequential enzyme activity for the enzyme:AuNP conjugates, and reaction efficiencies of greater than 70%. We here show that the knowledge of the conjugate stoichiometry and retained enzyme activity can lead to more efficient detection of acetylcholine by controlling the AChE:ChO ratio bound to the gold nanoparticle material. This approach of optimizing enzyme gold nanoparticle conjugates should be of great importance in the architecture of enzyme nanoparticle based biosensors to retain optimal sensor sensitivity

    Electrochemistry of Single-Vesicle Events

    Neuronal transmission relies on electrical signals and the transfer of chemical signals from one neuron to another. Chemical messages are transmitted from presynaptic neurons to neighboring neurons through the triggered fusion of neurotransmitter-filled vesicles with the cell plasma membrane. This process, known as exocytosis, involves the rapid release of neurotransmitter solutions that are detected with high affinity by the postsynaptic neuron. The type and number of neurotransmitters released and the frequency of vesicular events govern brain functions such as cognition, decision making, learning, and memory. Therefore, to understand neurotransmitters and neuronal function, analytical tools capable of quantitative and chemically selective detection of neurotransmitters with high spatiotemporal resolution are needed. Electrochemistry offers powerful techniques that are sufficiently rapid to allow for the detection of exocytosis activity and provides quantitative measurements of vesicle neurotransmitter content and neurotransmitter release from individual vesicle events. In this review, we provide an overview of the most commonly used electrochemical methods for monitoring single-vesicle events, including recent developments and what is needed for future research
