An investigation into the tension arising between natural language and mathematical language experienced by mechanical engineering students

This investigation is grounded within the concept of embodied cognition where the mind is considered to be part of a biological system. A first year undergraduate Mechanical Engineering cohort of students was tasked with explaining the behaviour of three balls of different masses being rolled down a ramp. The explanations given by the students highlighted the cognitive conflict between the everyday interpretation of the word energy and its mathematical use. The results showed that even after many years of schooling, students found it challenging to interpret the mathematics they had learned and relied upon pseudo-scientific notions to account for the behaviour of the balls.

Combining Taxonomies using Word2vec

Taxonomies have gained a broad usage in a variety of fields due to their extensibility, as well as their use for classification and knowledge organization. Of particular interest is the digital document management domain in which their hierarchical structure can be effectively employed in order to organize documents into content-specific categories. Common or standard taxonomies (e.g., the ACM Computing Classification System) contain concepts that are too general for conceptualizing specific knowledge domains. In this paper we introduce a novel automated approach that combines sub-trees from general taxonomies with specialized seed taxonomies by using specific Natural Language Processing techniques. We provide an extensible and generalizable model for combining taxonomies in the practical context of two very large European research projects. Because the manual combination of taxonomies by domain experts is a highly time consuming task, our model measures the semantic relatedness between concept labels in CBOW or skip-gram Word2vec vector spaces. A preliminary quantitative evaluation of the resulting taxonomies is performed after applying a greedy algorithm with incremental thresholds used for matching and combining topic labels.

Mindfulness and Spirituality as determinants of Existential Loneliness in the Dutch

Existential loneliness is a concept that is largely ignored in the psychological research tradition, although from a philosophical perspective it is deeply connected to inherent human longings of connection and meaning. This research investigated the relationship between existential loneliness and two variables that are theoretically closely related to the concepts of connection and meaning, namely mindfulness (connection to oneself and others) and spiritual well-being (connection to a larger whole). This was done in a sample of n = 180 individuals (61.7% female; mean age 41.72, SD = 12.16) of the Dutch population. A multiple regression analysis was conducted. It can be concluded that there is a negative relationship between mindfulness and existential loneliness, as well as between spiritual well-being and existential loneliness. This means that people with a higher level of mindfulness and/or a higher level of spiritual well-being experience a lower level of existential loneliness. At the same time, people with a lower level of mindfulness and/or spiritual well-being experience a lower level of existential loneliness. There are some limitations to this study, for example the use of a non-random sampling method, a limited sample group, a scale that has not been widely tested, and a potential bias towards the higher educated. However, these limitations are inherent to exploratory research and does not diminish the main strength of this thesis, namely that it has provided more insight into an important and prevalent societal phenomenon, that had not been extensively researched previously, that has so far only been addressed in more philosophical instead of scientific debates, and linked almost exclusively to negative concepts, such as terminal illness. This research provides a first understanding of two positive determinants of existential loneliness, which could potentially be used to help make sense of this inherently humane condition, as well as to actively cope with the potential (adverse) effects of it.

ERIC recommendations on TP53 mutation analysis in chronic lymphocytic leukemia.

Recent evidence suggests that - in addition to 17p deletion - TP53 mutation is an independent prognostic factor in chronic lymphocytic leukemia (CLL). Data from retrospective analyses and prospective clinical trials show that ∼5% of untreated CLL patients with treatment indication have a TP53 mutation in the absence of 17p deletion. These patients have a poor response and reduced progression-free survival and overall survival with standard treatment approaches. These data suggest that TP53 mutation testing warrants integration into current diagnostic work up of patients with CLL. There are a number of assays to detect TP53 mutations, which have respective advantages and shortcomings. Direct Sanger sequencing of exons 4-9 can be recommended as a suitable test to identify TP53 mutations for centers with limited experience with alternative screening methods. Recommendations are provided on standard operating procedures, quality control, reporting and interpretation. Patients with treatment indications should be investigated for TP53 mutations in addition to the work-up recommended by the International workshop on CLL guidelines. Patients with TP53 mutation may be considered for allogeneic stem cell transplantation in first remission. Alemtuzumab-based regimens can yield a substantial proportion of complete responses, although of short duration. Ideally, patients should be treated within clinical trials exploring new therapeutic agents.

Towards Night

Sixty artists explore the nocturnal. Curated by Tom Hammick. The evening hour too gives us the irresponsibility which darkness and lamplight bestow. We are no longer quite ourselves. – Virginia Woolf, Street Haunting: A London Adventure, 1930 Towards Night is an exhibition exploring the nocturnal through paintings, prints and drawings by over sixty artists. Drawing on the nineteenth century European Romantic tradition, the show surveys contemporary and historical connections to wonderment and dystopia at dusk, twilight, night and dawn. Towards Night juxtaposes key paintings and prints by Constable, Friedrich, Munch, Nolde, Palmer and Turner, some of the best known visionaries of the Romantic tradition with contemporary artists who work with the transformative aspects of nightfall to convey emotional responses of awe, anxiety and solitude, love and loss, revelry, insomnia, and journey’s end. The exhibition opens with direct and positive responses to the natural world; Marc Chagall’s exotic dreamlike evening in The Poet Reclining (1915) sits close to eighteenth century Indian miniatures depicting brightly painted figures offset against darkening monsoon clouds, and William Crozier’s Balcony at Night, Antibes (2007), of a plant, blue and iridescent against the cool night sky. As the exhibition progresses, the dystopias become darker and more disturbing, and the connections between artists and works intensify: Emma Stibbon’s Rome Aqueduct (2011) takes on a heightened sense of pathos alongside Caspar David Friedrich’s Winter Landscape (1811); Peter Doig’s cinematic Echo Lake (1998) conjures up an increased sense of contemporary angst; and Prunella Clough’s False Flower (1993), a magical tree defying brutalism by growing out of concrete, becomes more miraculous near Night Shift (2015) Nick Carrick’s tomblike high rise. Tom Hammick’s Violetta Alone (2015) and Michael Craig Martin’s Ash Tray (2015), reinforce hedonistic aspects of night-time revelry alongside Four AM, Betsy Dadd’s young woman drinking in the early hours of the morning and L.S. Lowry’s drunken people in a pub in The Crowd (1922). In the final room, a cluster of works explores dreams and insomnia, from Louise Bourgeois’ Spirals (2010) to Munch’s lovers embracing in The Kiss (1902). Tom Hammick, curator of the show said “This exhibition has grown way beyond its original conception, to become a magnificent survey of painting and printmaking from over two hundred years based around the central tenet of night. The exhibition is a kind of painterly response to the way figurative artists use their artistic heroes as starting points for their own work, both compositionally and emotionally.” Artists featured in Towards Night: Christiane Baumgarter, Michael Craig-Martin, Julian Opie, Will Gill, Merlin James, Howard Hodgkin, WillIam Scott, Patrick Caulfield, George Shaw, Stephen Chambers, Basil Beattie, Betsy Dadd, Christopher Le Brun, L.S Lowry, Andrew Cranston, David Willetts, James Fisher, Emma Stibbon, Vija Celmins, William Blake, William Crozier, Tom Hammick, Georgia Keeling, Helen Turner, Humphrey Ocean, Julian Bell, Craigie Aitchison, Mark Wright, Ken Kiff, Matthew Burrows, Andrzej Jackowski, Sarah Raphael, Nick Bodimeade, Nick Carrick, Mary Newcomb, Hurvin Anderson, Peter Doig, Phoebe Unwin, Danny Markey, Sara Lee, Simon Burton, Susie Hamilton, Marc Chagall, Alfred Wallis, Emil Nolde, J.M.W.

Competition-related factors directly influence preferences for facial cues of dominance in allies

Alliance formation is a critical dimension of social intelligence in political, social and biological systems. As some allies may provide greater ‘leverage’ than others during social conflict, the cognitive architecture that supports alliance formation in humans may be shaped by recent experience, for example in light of the outcomes of violent or non-violent forms intrasexual competition. Here we used experimental priming techniques to explore this issue. Consistent with our predictions, while men’s preference for dominant allies strengthened following losses (compared to victories) in violent intrasexual contests, women’s preferences for dominant allies weakened following losses (compared to victories) in violent intrasexual contests. Our findings suggest that while men may prefer dominant (i.e. masculine) allies following losses in violent confrontation in order to facilitate successful resource competition, women may ‘tend and befriend’ following this scenario and seek support from prosocial (i.e. feminine) allies and/or avoid the potential costs of dominant allies as long-term social partners. Moreover, they demonstrate facultative responses to signals related to dominance in allies, which may shape sex differences in sociality in light of recent experience and suggest that intrasexual selection has shaped social intelligence in humans.

Macrophage adaptation leads to parallel evolution of genetically diverseEscherichia colismall-colony variants with increased fitness in vivo and antibiotic collateral sensitivity

Small-colony variants (SCVs) are commonly observed in evolution experiments and clinical isolates, being associated with antibiotic resistance and persistent infections. We recently observed the repeated emergence of Escherichia coli SCVs during adaptation to the interaction with macrophages. To identify the genetic targets underlying the emergence of this clinically relevant morphotype, we performed whole-genome sequencing of independently evolved SCV clones. We uncovered novel mutational targets, not previously associated with SCVs (e.g. cydA, pepP) and observed widespread functional parallelism. All SCV clones had mutations in genes related to the electron-transport chain. As SCVs emerged during adaptation to macrophages, and often show increased antibiotic resistance, we measured SCV fitness inside macrophages and measured their antibiotic resistance profiles. SCVs had a fitness advantage inside macrophages and showed increased aminoglycoside resistance in vitro, but had collateral sensitivity to other antibiotics (e.g. tetracycline). Importantly, we observed similar results in vivo. SCVs had a fitness advantage upon colonization of the mouse gut, which could be tuned by antibiotic treatment: kanamycin (aminoglycoside) increased SCV fitness, but tetracycline strongly reduced it. Our results highlight the power of using experimental evolution as the basis for identifying the causes and consequences of adaptation during host-microbe interactions.

Organizational responses to technological discontinuities: the case of the American College of Radiology (ACR)

A long history of organizational research has shown that organizations are affected significantly by changes in technology. Scholars have given particular attention to the effects of so-called disruptive or discontinuous technological changes. Studies have repeatedly shown that established, incumbent organizations tend to suffer deep performance declines (and even complete demise) in the face of such changes, and researchers have devoted much attention to identifying the organizational conditions and processes that are responsible for this persistent and widespread pattern of adaptation failure. This dissertation, which examines the response of the American College of Radiology (ACR) to the emergence of nuclear magnetic resonance imaging technology (NMR), aims to contribute to this well-established research tradition in three distinct and important ways. First, it focuses on a fundamentally different type of organization, a professional association, rather than the technology producers examined in most prior research. Although technologies are well known to be embedded in “communities” that include technology producers, suppliers, customers, governmental entities, professional societies, and other entities, most prior research has focused on the responses and ultimate fate of producers alone. Little if any research has explored the responses of professional organizations in particular. Second, the study employs a sophisticated process methodology that identifies the individual events that make up the organization’s response to technological change, as well as the overall sequence through which these events unfold. This process approach contrasts sharply with the variance models used in most previous studies and offers the promise of developing knowledge about how adaptation ultimately unfolds (or fails to). Finally, the project also contributes significantly through its exploration of an apparently successful case of adaptation to technological change. Though nuclear magnetic resonance imaging posed a serious threat to the ACR and its members, this threat appears to have been successfully managed and overcome. Although the unique nature of the organization and the technology under study place some important limits on the generalizablity of this research, its findings nonetheless provide some important basic insights about the process through which social organizations can successfully adapt to discontinuous technological changes. These insights, which may also be of substantial relevance to technology producer organizations, will also be elaborated.
