Digital twins and deep maps
Full text linkMapping is now thoroughly digital at all stages of production and maps are widely used in digital form. This digital turn has transformed the nature of mapping and maps. Maps need no longer be static representations, but rather constitute spatial media, providing an interactive, dynamic means for creating, discussing, and sharing spatial information and mediating spatial practices. This has included the development of 3D mapping, including nascent digital twins and digital deep maps. In this short paper, we reflect on our attempts to produce a 3D city information model for Dublin that acts as a basic digital twin, which we have also used to explore deep mapping, as well as map projecting data onto a printed 3D map model of the city. We consider what digital twins and deep maps mean for how we understand the nature of mapping, arguing that they produce a dyadic intertwining of map and territory; a literal, material expression of post‐representational, ontogenetic conceptions of mapping
The effect of task switching on productivity: evidence from major league baseball pitchers
Full text linkThere are few opportunities, outside of a laboratory setting, to study how workers respond to the demands of task switching. A priori, task switching might either harm or benefit productivity, and thus it becomes an empirical question. Faced with difficulties in the measurement of productivity and task switching, we turn to an industry that produces accurate, detailed, and comparable measures of worker production, namely starting pitchers in Major League Baseball. Our results suggest that task switching, between pitching and batting, can improve subsequent pitching performance, though heterogeneity in this effect is present. We discuss implications for wider labour market settings
The Long‐Term Effects of In Utero Exposure to Rubella
Full text linkA rubella infection in early pregnancy poses a significant risk of damage to the foetus. In this paper, we examine the later‐life impact of a rubella outbreak that occurred in Ireland in 1956. Matching the outcomes of individuals born in 1954–1957 in the 2016 Irish Census of Population to the county‐level rubella incidence rate that was prevailing when respondents were in utero in early pregnancy, we find that one extra rubella case per 10,000 population is associated with between 0.4% and 1.2% point increases in the probability of having lower levels of educational attainment, being in poor health and having a disability in later life
Reaching out: Exhibition: An Damer a landmark in Irish Theatre
Full text linkAn exhibition to mark Seachtain na Gaeilge 2025, was presented by Special Collections & Archives at Maynooth University Library, about the Damer Theatre. An Damer was an Irish language theatre operated by Gael Linn in the Unitarian Church, Saint Stephen’s Green, Dublin from 1955 until 1981
Urban digital twins: Digital twins for participatory steering
Full text linkOriginating in the field of manufacturing, the Digital Twin (DT) concept is now being applied across a range of application domains, from personal healthcare to whole Earth observation. Despite enthusiasm for DTs, uncertainties have arisen concerning their lack of definition and technical specificity. This paper reassesses the concept with particular consideration for its application to cities in the form of Urban Digital Twins (UDTs). Rather than identifying DTs with a particular set of technologies, we instead understand them as embodying a core ‘conceptual model’ describing a mechanism for control based on the generation and feedback of information, elsewhere characterised as a ‘steering representation’. By aligning their use with more participatory forms of governance involving the ‘commoning’ of city information, we argue that UDTs might then provide powerful new means for participation in urban planning and governance through the support they provide for communication, collective sensemaking and shared oversight
Hydrogen Evolution-Directed Electrodeposition of a Cobalt Selenide/Cobalt Oxide Electrocatalyst for the Hydrogen and Oxygen Evolution Reactions
Full text linkAs more emphasis is placed on renewable energy worldwide, the electrochemical splitting of water has attracted considerable attention. Herein, a simple and cost-effective electrocatalyst was studied for both the hydrogen and oxygen evolution reactions. The electrocatalyst consisted of an electrodeposited cobalt diselenide/cobalt oxide composite, which was fabricated from an aqueous solution containing cobalt and selenium salts on a glassy carbon substrate. The optimal deposition conditions were found to be a fixed potential at −1.2 V vs Ag/AgCl for 400 s. At this relatively low potential, the electrodeposition process is accompanied by the hydrogen evolution reaction, resulting in a hierarchical, flower-like morphology. The electrochemical active surface area was calculated to be 89 cm2 in 1.0 M KOH and 72 cm2 in 0.5 M H2SO4. This electrocatalyst facilitated the hydrogen evolution reaction in both KOH and H2SO4 solutions, with overpotentials of 305 and 205 mV at 10 mA cm–2, respectively. Similarly, good oxygen evolution activity was achieved in KOH. The electrocatalyst demonstrated good stability over a 24 h period, with evidence of improved oxygen evolution activity following the stability studies
Glycoproteomic and Single-Protein Glycomic Analyses Reveal Zwitterionic N-Glycans on Natural and Recombinant Proteins Derived From Insect Cells
Full text linkInsect cell lines are frequently
used for expression of
recombinant glycoproteins,
including vaccines. Using two
independent approaches, we
show that the endogenous Nglycomes of High Five and Sf9
cells contain species-specific
anionic N-glycan structures with
different combinations of
phosphorylcholine, fucose,
hexuronic acid and/or pentose.
Glycans with phosphorylcholine
and fucose epitopes were also
found on influenza hemagglutinin
and SARS-CoV-2 Spike
expressed in either cell line. Our
data highlight the need for open
search strategies for identifying
glycans present on recombinant
glycoproteins from nonmammalian sources
“Describe the problem properly”: Teju Cole’s aesthetic of uncertainty
Full text linkThis thesis is an analysis of the intermedial body of work by the work by the Nigerian American writer and photographer Teju Cole (1976 -). I argue that his work is best understood as a single, overarching project, unified by what I term Cole's 'aesthetic of uncertainty.' This aesthetic uses uncertainty and cognate terms such as hybridity, ambiguity, indeterminacy and opacity to stimulate and engage his audience by leaving them unsure, through different means and to different ends. I show how in his fictional work this happens narratologically, but also by blurring boundaries of genre, and subverting market expectations. Generic indeterminacy also plays a role in Cole's visual mode, as he combines images and text in innovative, productive ways that provoke his audience to examine their own understanding of photography's affordances, and how they look at the world. I then consider the complex strategies of mediation that Cole utilises, through the lens of recent work by Anna Kornbluh. The philosophical and musical manifestations of uncertainty are under consideration in the final main chapter, as I explore the ethos of the blues and Black Pragmatism in Cole's most recent novel. I conclude by considering Cole's uneasy status as a public intellectual and his own uncertainty in the role. I use a mix of methodological approaches that are appropriate to each chapter, but each one is built on a foundation of close reading that seeks to locate the texts, whether fictional, factual, photographic, or a hybrid of these forms, as part of a vast network of informing intertexts
Plain sailing or choppy water? Maintaining interpersonal trusting relationships in times of uncertainty
Full text linkInterpersonal trusting relationships frequently experience relational threats that require both parties to engage actively in trust maintenance efforts. Yet, trust research has tended to focus on trust formation, or trust repair in the case of a violation, and offers us little insight regarding how these more ambiguous threats to trusting relationships are experienced and overcome relationally. To provide novel insight on this topic, this exploratory study gathers dyadic interview data from 26 manager–employee trusting relationships regarding their experience of relational threats and their proactive efforts to overcome these negative relational experiences. Findings show that the experience of a relational threat triggers a three-stage trust maintenance process that includes an assessment phase, an active maintenance phase, and an outcome phase. Threats are assessed at the individual level via cognitive and affective sensemaking, while trust maintenance efforts (creating a shared mental model, cognitive and structural reassurance, and dyadic problem solving) require dyadic counterparts to act with mutual agency to overcome the relational threat and avoid a loss of trust. Trust maintenance processes support dyads to either maintain or strengthen their existing trusting relationships. Our findings advance our theoretical understanding of interpersonal trust maintenance by demonstrating that this process unfolds across three phases and can lead to different outcomes for dyads’ trusting relationships. We offer practical guidelines to safeguard existing trusting relationships, as well as a new agenda for trust scholars to extend our theorizing
