Assessing pollinators’ use of floral resource subsidies in agri-environment schemes: An illustration using Phacelia tanacetifolia and honeybees

Honeybees (Apis mellifera L.) are frequently used in agriculture for pollination services because of their abundance, generalist floral preferences, ease of management and hive transport. However, their populations are declining in many countries. Agri-Environment Schemes (AES) are being implemented in agricultural systems to combat the decline in populations of pollinators and other insects. Despite AES being increasingly embedded in policy and budgets, scientific assessments of many of these schemes still are lacking, and only a few studies have examined the extent to which insect pollinators use the floral enhancements that are part of AES and on which floral components they feed (i.e., pollen and/or nectar)

Blended Stakeholder Participation for Responsible Information Systems Research

Researchers often conduct information systems (IS) research under the assumption that technology use leads to positive outcomes for different stakeholders. However, many IS studies demonstrate limited evidence of having engaged with the stakeholders that they claim benefit and speak on behalf of. Therefore, we can unsurprisingly find many examples in which technology use failed to make the world a better place or, worse still, contributed towards unintended negative outcomes. Given these concerns, calls have recently emerged for responsible research and innovation (RRI) studies in IS to understand how different stakeholder groups can have a voice in complex socio-technical issues. In this paper, we take steps towards addressing this call by presenting case study findings from a responsible IS research project that combined “blended” face-to-face and online participatory techniques. The case study relates to a large-scale consultation in a 24-month European project that involved 30 countries. The project engaged over 1,500 stakeholders in co-creating future research agendas for the European Union. We discuss case study findings using Stilgoe, Owen, and Macnaghten’s (2013) framework and reflect on lessons learned for responsible IS research going forward

The Pragmatic School of Thought in Open Science Practice: A Case Study of Multi-stakeholder Participation in Shaping the Future of Internet Governance

The internet is a disruptive technology that continues to define our modern world. However, numerous ethical challenges remain for internet governance going forward, e.g. surveillance capitalism, terrorism and radicalisation. The ‘pragmatic’ school of thought in open science advocates for collaboration between diverse stakeholder groups (e.g. citizens, academics, practitioners, policymakers) to ensure an informed, and positive imprint for change. However, our understanding of how open science can be used for assimilating knowledge on complex socio-political issues remains nascent. To address this gap, we present findings from ‘We, the Internet’, a global consultation project which utilised open science practices such as stakeholder-led evaluations and open access publications to engage stakeholders in dialogue around the future of internet governance. Our findings discuss emergent themes on the future of internet governance, and highlight the potential of open science to mobilise groups and combat public scepticism in policy-making

Open E-Learning Platforms and the Design-Reality Gap : Exploring the Impact of User-Perceived Functional Affordances

Open e-learning platforms and the design–reality gap : an affordance theory perspective

Purpose The dropout rates of open e-learning platforms are often cited as high as 97%, with many users discontinuing their use after initial acceptance. This study aims to explore this anomaly through the lens of affordances theory, revealing design-reality gaps between users' diverse goals and the possibilities for action provided by an open IT artefact. Design/methodology/approach A six-month case study was undertaken to investigate the design implications of user-perceived affordances in an EU sustainability project which developed an open e-learning platform for citizens to improve their household energy efficiency. Thematic analysis was used to reveal the challenges of user continuance behaviour based on how an open IT artefact supports users in achieving individual goals (e.g. reducing energy consumption in the home) and collective goals (lessening the carbon footprint of society). Findings Based on the findings, the authors inductively reveal seven affordances related to open e-learning platforms: informing, assessment, synthesis, emphasis, clarity, learning pathway and goal-planning. The findings centre on users' perception of these affordances, and the extent to which the open IT artefact catered to the goals and constraints of diverse user groups. Open IT platform development is further discussed from an iterative and collaborative perspective in order to explore different possibilities for action. Originality/value The study contributes towards research on open IT artefact design by presenting key learnings on how the designers of e-learning platforms can bridge design-reality gaps through exploring affordance personalisation for diverse user groups. This can inform the design of open IT artefacts to help ensure that system features match the expectations and contextual constraints of users through clear action-oriented possibilities.Peer reviewe

Feeding tube securement in critical illness: Implications for safety

© 2018 MA Healthcare Ltd Over 50% of tape-secured feeding tubes are inadvertently lost. The impact of nasal bridle securement on nasogastric (NG) and nasointestinal (NI) tube loss, outcome and duration of use was determined from 1 October 2014 (NG) and 1 January 2010 respectively to 31 December 2017. From this and published data, the potential impact of nasal bridles on major complications was determined. Use of nasal bridles was independently associated with: an 80% reduction in inadvertent NI tube loss (odds ratio (OR): 95% confidence interval (CI): 0.2: 0.12-0.33,

Scorpion venom increases acetylcholine release by prolonging the duration of somatic nerve action potentials

Scorpionism is frequently accompanied by a massive release of catecholamines and acetylcholine from peripheral nerves caused by neurotoxic peptides present in these venoms, which have high specificity and affinity for ion channels. Tityus bahiensis is the second most medically important scorpion species in Brazil but, despite this, its venom remains scarcely studied, especially with regard to its pharmacology on the peripheral (somatic and autonomic) nervous system. Here, we evaluated the activity of T. bahiensis venom on somatic neurotransmission using myographic (chick and mouse neuromuscular preparations), electrophysiological (MEPP, EPP, resting membrane potentials, perineural waveforms, compound action potentials) and calcium imaging (on DRG neurons and muscle fibres) techniques. Our results show that the major toxic effects of T. bahiensis venom on neuromuscular function are presynaptically driven by the increase in evoked and spontaneous neurotransmitter release. Low venom concentrations prolong the axonal action potential, leading to a longer depolarization of the nerve terminals that enhances neurotransmitter release and facilitates nerve-evoked muscle contraction. The venom also stimulates the spontaneous release of neurotransmitters, probably through partial neuronal depolarization that allows calcium influx. Higher venom concentrations block the generation of action potentials and resulting muscle twitches. These effects of the venom were reversed by low concentrations of TTX, indicating voltage-gated sodium channels as the primary target of the venom toxins. These results suggest that the major neuromuscular toxicity of T. bahiensis venom is probably mediated mainly by α- and β-toxins interacting with presynaptic TTX-sensitive ion channels on both axons and nerve terminals
