The expert cure? Exploring the restorative potential of expertise for public satisfaction with parties

The declining legitimacy of political parties has become something of a truism in political science discourse. Less often reflected upon is how these legitimacy problems could potentially be resolved. This article contributes to this underexplored issue by examining the restorative potential of expertise as a supplement to intra-party democracy. Building on an established literature on Stealth Democracy, we explore the potential for expert-inspired reforms to boost citizens’ satisfaction with parties. Using original survey questions, we provide evidence that a perceived lack of expert engagement in parties predicts citizen dissatisfaction, before using deliberative workshop data to distil traits that define the appeal of experts and expertise. This mixed-methods approach allows us to demonstrate some common desires of which parties should be aware, but also traits that make these ideas difficult to realise. Combining these insights, we argue that while expertise has appeal, parties face considerable challenges in satisfying citizens’ desires

The post-pandemic lecture : views from academic staff across the UK

COVID-19 forced the closure of UK universities. One effect of this was a change in how lectures, and their recordings, were made and used. In this research, we aimed to address two related research questions. Firstly, we aimed to understand how UK universities replaced in-person lectures and, secondly, to establish what academic staff believed the post-pandemic lecture would look like. In a mixed-methods study, we collected anonymous quantitative and qualitative data from 87 academics at 36 UK institutions. Analysis revealed that respondents recognised the value and importance of interactive teaching and indicated that the post-pandemic lecture would and should make greater use of this. Data also revealed positive views of lecture capture, in contrast to pre-pandemic studies, and demonstrated that staff recognised their value for those who were unable to attend, or who had specific learning differences. However, staff also recognised the value of asynchronous lecture videos within a blended or flipped approach. This study provides evidence that the pandemic has engendered changes in attitudes and practices within UK higher education that are conducive to educational reform

Dynamics of intra-party organisation in the digital age : a grassroots analysis of digital adoption

Over recent decades, scholars have explored political parties’ adoption of digital technology. Tracing successive eras of change, scholarship has examined the degree to which digital disrupts or embeds traditional power structures—with many studies finding evidence of ‘controlled-interactivity’. In this article, we revisit debates around the adoption of digital tools from a bottom-up perspective. Moving beyond attempts to categorise elite strategies for digital adoption, we consider practices on the ground to document how, in practice, digital technology is being taken up and used. Using a case study of the UK Labour Party, we categorise a range of different practices, highlighting and theorising the presence of digital adherents, laggards, entrepreneurs, renegades and refuseniks. Discussing the drivers of these practices, we offer new insight into variations in digital adoption and consider the significance of these trends for our understanding of party organisation

Altered visual processing in a rodent model of Attention-Deficit Hyperactivity Disorder

A central component of Attention-Deficit Hyperactivity Disorder (ADHD) is increased distractibility, which is linked to the superior colliculus (SC) in a range of species, including humans. Furthermore, there is now mounting evidence of altered collicular functioning in ADHD and it is proposed that a hyper-responsive SC could mediate the main symptoms of ADHD, including distractibility. In the present study we have provided a systematic characterization of the SC in the most commonly used and well-validated animal model of ADHD, the spontaneously hypertensive rat (SHR). We examined collicular-dependent orienting behavior, local field potential (LFP) and multiunit responses to visual stimuli in the anesthetized rat and morphological measures in the SHR in comparison to the Wistar Kyoto (WKY) and Wistar (WIS). We found that SHRs remain responsive to a repeated visual stimulus for more presentations than control strains and have a longer response duration. In addition, LFP and multiunit activity within the visually responsive superficial layers of the SC showed the SHR to have a hyper-responsive SC relative to control strains, which could not be explained by altered functioning of the retinocollicular pathway. Finally, examination of collicular volume, neuron and glia densities and glia:neuron ratio revealed that the SHR had a reduced ratio relative to the WKY which could explain the increased responsiveness. In conclusion, this study demonstrates strain-specific changes in the functioning and structure of the SC in the SHR, providing convergent evidence that the SC might be dysfunctional in ADHD

The effects of tryptophan loading on Attention Deficit Hyperactivity in adults:A remote double blind randomised controlled trial

BackgroundDespite the impact and prevalence of Attention Deficit Hyperactivity Disorder (ADHD), current treatment options remain limited and there is a drive for alternative approaches, including those building on evidence of a role for tryptophan (TRP) and serotonin (5-HT). This study aimed to evaluate the effect of acute TRP loading on attention and impulsivity in adults with ADHD.Trial design and methods We conducted a remote double blind randomised controlled trial (RCT) using TRP loading to examine the effects of a balanced amino acid load in comparison to low and high TRP loading in individuals with ADHD (medicated, N = 48, and unmedicated, N = 46) and controls (N = 50). Participants were randomised into one of three TRP treatment groups using stratified randomisation considering participant group and gender using a 1:1:1 ratio. Baseline testing of attention and impulsivity using the Test of Variables of Attention Task, Delay Discounting Task, and Iowa Gambling Task was followed by consumption of a protein drink (BAL, LOW, or HIGH TRP) before repeated testing. Results and ConclusionsNo effects of TRP were observed for any of the measures. In the present study, TRP loading did not impact on any measure of attention or impulsivity in those with ADHD or Controls. The findings need to be confirmed in another trial with a larger number of patients that also considers additional measures of dietary protein, plasma TRP and aggression.

Effect of methylphenidate on visual responses in the superior colliculus in the anaesthetised rat: Role of cortical activation

The mechanism of action of psychostimulant drugs in the treatment of Attention Deficit Hyperactivity Disorder is still largely unknown, although recent evidence suggests one possibility is that the drugs affect the superior colliculus (SC). We have previously demonstrated that systemically administered d-amphetamine attenuates/abolishes visual responses to wholefield light flashes in the superficial layers of the SC in anaesthetised rats, and the present study sought to extend this work to methylphenidate (MPH). Anaesthetised rats were administered MPH at a range of doses (or saline) and subjected to monocular wholefield light flashes at two intensities, juxta-threshold and super-threshold. In contrast to d-amphetamine, systemic MPH produced an enhancement of visual activity at both intensities. Methylphenidate was also found to produce activation of the cortical EEG in anaesthetised rats. Furthermore, cortical activation induced by electrical stimulation of the pons was found to enhance visual responses in superficial layers of the SC, and when MPH was paired with pontine-induced cortical activation, the response-enhancing effects of MPH were substantially attenuated. Taken together, the results suggest that the enhancement of visual responses in the superficial layers of the SC by MPH in the anaesthetised rat is an artefact of the drug’s interaction with cortical arousal

Sign-tracking and goal-tracking in humans: utilising eye-tracking in clinical and non-clinical populations.

Background In Pavlovian conditioning, learned behaviour varies according to the perceived value of environmental cues. For goal-trackers (GT), the cue merely predicts a reward, whilst for sign-trackers (ST), the cue holds incentive value. The sign-tracking/goal-tracking model is well-validated in animals, but translational work is lacking. Despite the model’s relevance to several conditions, including attention deficit hyperactivity disorder (ADHD), we are unaware of any studies that have examined the model in clinical populations. Methods The current study used an eye-tracking Pavlovian conditioning paradigm to identify ST and GT in non-clinical (N = 54) and ADHD (N = 57) participants. Eye movements were recorded whilst performing the task. Dwell time was measured for two areas of interest: sign (i.e., cue) and goal (i.e., reward), and an eye-gaze index (EGI) was computed based on the dwell time sign-to-goal ratio. Higher EGI values indicate sign-tracking behaviour. ST and GT were determined using median and tertiary split approaches in both samples. Results Despite greater propensity for sign-tracking in those with ADHD, there was no significant difference between groups. The oculomotor conditioned response was reward-specific (CS+) and present, at least partly, from the start of the task indicating dispositional and learned components. There were no differences in externalising behaviours between ST and GT for either sample. Conclusions Sign-tracking is associated with CS+ trials only. There may be both dispositional and learned components to sign-tracking, potentially more common in those with ADHD. This holds translational potential for understanding individual differences in reward-learning

The effects of different exercise approaches on attention deficit hyperactivity in adults: a randomised controlled trial

Attention deficit hyperactivity disorder (ADHD) results in significant functional impairment. Current treatments, particularly for adults, are limited. Previous research indicates that exercise may offer an alternative approach to managing ADHD, but research into different types of exercise and adult populations is limited. The aim of this study was to examine the effects of acute exercise (aerobic cycling vs mind-body yoga exercises) on symptoms of ADHD in adults. Adults with ADHD (N = 82) and controls (N = 77) were randomly allocated to 10 min of aerobic (cycling) or mind-body (Hatha yoga) exercise. Immediately before and after exercise, participants completed the Test of Variables of Attention task, Delay Discounting Task, and Iowa Gambling Task to measure attention and impulsivity. Actigraphy measured movement frequency and intensity. Both groups showed improved temporal impulsivity post-exercise, with cycling beneficial to all, whilst yoga only benefited those with ADHD. There were no effects of exercise on attention, cognitive or motor impulsivity, or movement in those with ADHD. Exercise reduced attention and increased movement in controls. Exercise can improve temporal impulsivity in adult ADHD but did not improve other symptoms and worsened some aspects of performance in controls. Exercise interventions should be further investigated
