Trait rumination is a habitual response to negative experiences that can emerge during adolescence, increasing risk of depression. Trait rumination is correlated with poor inhibitory control (IC) and altered default mode network (DMN) and cognitive control network (CCN) engagement. Provoking state rumination in high ruminating youth permits investigation of rumination and IC at the neural level, highlighting potential treatment targets.
Methods:
Fifty-three high-ruminating youth were cued with an unresolved goal that provoked state rumination, then completed a modified Sustained Attention to Response Task (SART) that measures IC (commissions on no-go trials) in a functional MRI study. Thought probes measured state rumination about that unresolved goal and task-focused thoughts during the SART.
Results:
Greater state rumination during the SART was correlated with more IC failures. CCN engagement increased during rumination (relative to task-focus), including left dorsolateral prefrontal cortex and dorsal-medial prefrontal cortex. Relative to successful response suppression, DMN engagement increased during IC failures amongst individuals with higher state and trait rumination. Exploratory analyses suggested more bothersome unresolved goals predicted higher left DLPFC activation during rumination.
Limitations:
The correlational research design did not permit a direct contrast of causal accounts of the relationship between rumination and IC.
Conclusions:
State rumination was associated with impaired IC and disrupted modulation of DMN and CCN. Increased CCN engagement during rumination suggested effortful suppression of negative thoughts, and this was greater for more bothersome unresolved goals. Relative task disengagement was observed during rumination-related errors. DMN-CCN dysregulation in high-ruminating youth may be an important treatment target.National Institute of Mental Healt
The Council of Europeâs Framework of Competences for Democratic Culture: Hope for democracy or an allusive Utopia?
Democracies around the world are increasingly polarized along political and cultural lines. To address these challenges, in 2016, the Council of Europe (CoE) produced a model of twenty competences for democratic culture. In 2018, this same model became the basis of the Reference Framework of Competences for Democratic Culture (RFCDC). The RFCDC provides pedagogical instructions to help implement these competences. Together, I call this set of materials âthe Frameworkâ.
This thesis begins with the premise that utopia has long played an important role in the way power is maintained or resisted in democratic education. It questions the assumption that democratic culture can be cultivated instrumentally through policy- based competences without imposing power on subjects and views this assumption to be utopian. It thus excavates the potential utopian ideals at play in the Framework using âhidden utopiasâ as a conceptual lens and method, which draws inspiration from the theories of MichĂšl Foucault, Ernst Bloch and Ruth Levitas.
It investigates how using âhidden utopiasâ as a theoretical lens might facilitate a deeper understanding of the nature and purpose of the Framework, how implicit utopias might be at play, how this could be problematic and how these theories might shed light on the application of the Framework in pedagogical contexts. The contribution of this thesis is to make visible potential utopias at the heart of the Framework. It suggests that making implicit utopias visible in democratic education can help educators and learners engage with these discourses in critical and innovative ways and think beyond them
More-than-words: Reconceptualising Two-year-old Childrenâs Onto-epistemologies Through Improvisation and the Temporal Arts
This thesis project takes place at a time of increasing focus upon two-year-old children and the words they speak. On the one hand there is a mounting pressure, driven by the school readiness agenda, to make children talk as early as possible. On the other hand, there is an increased interest in understanding childrenâs communication in order to create effective pedagogies. More-than-words (MTW) examines an improvised art-education practice that combines heterogenous elements: sound, movement and materials (such as silk, string, light) to create encounters for young children, educators and practitioners from diverse backgrounds. During these encounters, adults adopt a practice of stripping back their words in order to tune into the polyphonic ways that children are becoming-with the world.
For this research-creation, two MTW sessions for two-year-old children and their carers took place in a specially created installation. These sessions were filmed on a 360Ë camera, nursery school iPad and on a specially made child-friendly Toddler-cam (Tcam) that rolled around in the installation-event with the children. Through using the frameless technology of 360Ë film, I hoped to make tangible the relation and movement of an emergent and improvised happening and the way in which young children operate fluidly through multiple modes.
Travelling with posthuman, Deleuzio-Guattarian and feminist vital material philosophy, I wander and wonder speculatively through practice, memory, and film data as a bag lady, a Haraway-ian writer/artist/researcher-creator who resists the story of the wordless child as lacking and tragic; the story that positions the word as heroic. Instead, through returning to the uncertainty of improvisation, I attempt to tune into the savage, untamed and wild music of young childrenâs animistic onto-epistemologies

Sensing Collectives: Aesthetic and Political Practices Intertwined
Are aesthetics and politics really two different things? The book takes a new look at how they intertwine, by turning from theory to practice. Case studies trace how sensory experiences are created and how collective interests are shaped. They investigate how aesthetics and politics are entangled, both in building and disrupting collective orders, in governance and innovation. This ranges from populist rallies and artistic activism over alternative lifestyles and consumer culture to corporate PR and governmental policies. Authors are academics and artists. The result is a new mapping of the intermingling and co-constitution of aesthetics and politics in engagements with collective orders

Investigating the Effects of Network Dynamics on Quality of Delivery Prediction and Monitoring for Video Delivery Networks
Video streaming over the Internet requires an optimized delivery system given the advances in network architecture, for example, Software Defined Networks. Machine Learning (ML) models have been deployed in an attempt to predict the quality of the video streams. Some of these efforts have considered the prediction of Quality of Delivery (QoD) metrics of the video stream in an effort to measure the quality of the video stream from the network perspective. In most cases, these models have either treated the ML algorithms as black-boxes or failed to capture the network dynamics of the associated video streams.
This PhD investigates the effects of network dynamics in QoD prediction using ML techniques. The hypothesis that this thesis investigates is that ML techniques that model the underlying network dynamics achieve accurate QoD and video quality predictions and measurements. The thesis results demonstrate that the proposed techniques offer performance gains over approaches that fail to consider network dynamics. This thesis results highlight that adopting the correct model by modelling the dynamics of the network infrastructure is crucial to the accuracy of the ML predictions. These results are significant as they demonstrate that improved performance is achieved at no additional computational or storage cost. These techniques can help the network manager, data center operatives and video service providers take proactive and corrective actions for improved network efficiency and effectiveness
Frivolous Floodgate Fears
When rejecting plaintiff-friendly liability standards, courts often cite a fear of opening the floodgates of litigation. Namely, courts point to either a desire to protect the docket of federal courts or a burden on the executive branch. But there is little empirical evidence exploring whether the adoption of a stricter standard can, in fact, decrease the filing of legal claims in this circumstance. This Article empirically analyzes and theoretically models the effect of adopting arguably stricter liability standards on litigation by investigating the context of one of the Supreme Courtâs most recent reliances on this argument when adopting a stricter liability standard for causation in employment discrimination claims. In 2013, the Supreme Court held that a plaintiff proving retaliation under Title VII of the Civil Rights Act must prove that their participation in a protected activity was a but-for cause of the adverse employment action they experienced. Rejecting the arguably more plaintiff-friendly motivating-factor standard, the Court stated, â[L]essening the causation standard could also contribute to the filing of frivolous claims, which would siphon resources from efforts by employer[s], administrative agencies, and courts to combat workplace harassment.â Univ. of Tex. Sw. Med. Ctr. v. Nassar, 570 U.S. 338, 358 (2013). And over the past ten years, the Court has overturned the application of motivating-factor causation as applied to at least four different federal antidiscrimination statutes. Contrary to the Supreme Courtâs concern that motivating-factor causation encourages frivolous charges, many employment law scholars worry that the heightened but-for standard will deter legitimate claims. This Article empirically explores these concerns, in part using data received from the Equal Employment Opportunity Commission (EEOC) through a Freedom of Information Act (FOIA) request. Specifically, it empirically tests whether the adoption of the but-for causation standard for claims filed under the Age Discrimination in Employment Act and by federal courts of appeals under the Americans with Disabilities Act has impacted the filing of discrimination claims and the outcome of those claims in federal court. Consistent with theory detailed in this Article, the empirical analysis provides evidence that the stricter standard may have increased the docket of the federal courts by decreasing settlement within the EEOC and during litigation. The empirical results weigh in on concerns surrounding the adoption of the but-for causation standard and provide evidence that the floodgates argument, when relied on to deter frivolous filings by changing liability standards, in fact, may do just the opposite by decreasing the likelihood of settlement in the short term, without impacting the filing of claims or other case outcomes
