How do people interleave attention when multitasking? One dominant account is that the completion of a subtask serves as a cue to switch tasks. But what happens if switching solely at subtask boundaries led to poor performance? We report a study in which participants manually dialed a UK-style telephone number while driving a simulated vehicle. If the driver were to exclusively return his or her attention to driving after completing a subtask (i.e., using the single break in the xxxxx-xxxxxx representational (...) structure of the number), then we would expect to see a relatively poor driving performance. In contrast, our results show that drivers choose to return attention to steering control before the natural subtask boundary. A computational modeling analysis shows that drivers had to adopt this strategy to meet the required performance objective of maintaining an acceptable lateral position in the road while dialing. Taken together these results support the idea that people can strategically control the allocation of attention in multitask settings to meet specific performance criteria. (shrink)

We report the results of a dual-task study in which participants performed a tracking and typing task under various experimental conditions. An objective payoff function was used to provide explicit feedback on how participants should trade off performance between the tasks. Results show that participants’ dual-task interleaving strategy was sensitive to changes in the difficulty of the tracking task and resulted in differences in overall task performance. To test the hypothesis that people select strategies that maximize payoff, a Cognitively Bounded (...) Rational Analysis model was developed. This analysis evaluated a variety of dual-task interleaving strategies to identify the optimal strategy for maximizing payoff in each condition. The model predicts that the region of optimum performance is different between experimental conditions. The correspondence between human data and the prediction of the optimal strategy is found to be remarkably high across a number of performance measures. This suggests that participants were honing their behavior to maximize payoff. Limitations are discussed. (shrink)

We test people's ability to optimize performance across two concurrent tasks. Participants performed a number entry task while controlling a randomly moving cursor with a joystick. Participants received explicit feedback on their performance on these tasks in the form of a single combined score. This payoff function was varied between conditions to change the value of one task relative to the other. We found that participants adapted their strategy for interleaving the two tasks, by varying how long they spent on (...) one task before switching to the other, in order to achieve the near maximum payoff available in each condition. In a second experiment, we show that this behavior is learned quickly and remained stable for as long as the payoff function did not change. The results of this work show that people are adaptive and flexible in how they prioritize and allocate attention in a dual-task setting. However, it also demonstrates some of the limits regarding people's ability to optimize payoff functions. (shrink)

Educationalists are currently engaging with Jacques Rancière’s thought on emancipation and equality. The focus of this paper is on what initiates the process that starts emancipation. With reference to teachers the question is: how do teachers become emancipated? This paper discusses how the teacher’s life is made ‘sensible’ and how sense is distributed in her life. Two stories are taken from Rancière’s own work, that of Ingrid Bergman and Joseph Jacotot, that give us an indication of the initiation process of (...) emancipation. Then I will see this in relation to the teacher, Mr Briggs, who is one of the main characters of the play Our Day Out (1987) by Willy Russell. (shrink)

This paper reflects on the establishment of an Ethics Education Programme for school pupils aged between five and sixteen years who opt out of Catholic Religious Education in Malta. It needs to be seen in the light of the changing demography of Malta and the increasing secularisation of the country, as well as to the growing racism, islamophobia and rejection of the Other to be found all over Europe. We question if the Ethics Education Programme, in its commitment to ‘totalising’ (...) western ideals of rationality, autonomy, and universal values, is itself rooted in discomfort with the Other and constitutes a form of ethical violence. The work of Emmanuel Levinas on Otherness, sameness and violence is central to this paper. (shrink)

Early intervention comes in-between the lives of children, families and teachers. This article uses part of a report written by an educational psychologist about a little girl to question the nature of intervention through Rancière’s writings. As children and parents are seen as put into the position of inadequacy, they require such intervention, which in turn makes them more inadequate. The article goes on to highlight the numerous ‘givings’ involved in early intervention, through Derrida’s writing. However, such giving is questioned (...) as creating expectations that receivers of the gift must fulfil, thus nullifying the gift. The conclusion suggests that starting from a perspective of equality and acknowledging the aporia involved could help the people in this scenario to take a different approach. (shrink)

This paper draws upon Deleuze and Guattari's ideas to suggest a different kind of reading of a narrative of a mother of a child with severe disability, and thus a different kind of ethical response to them. This reading gives readers the possibility of opening up experiences of parents and children with disability, rather than compartmentalising such stories. The reader becomes, is transformed, through reading these narratives and through engaging with the intensities which are recognised in the text, asking the (...) question ‘Does it work for me?’ This is what Gilles Deleuze calls ‘reading with love’.

This paper reports on a study of teachers’ perceptions of teaching and learning in Scotland during the COVID-19 pandemic through the lens of engaged pedagogy and the ideas of bell hooks. It aimed to explore the different ways that teachers experienced teaching and learning during this time and the impact this may have had on teacher identity. Sixty teachers and head teachers were interviewed using MS Teams in the period April-June, 2020. For this paper, 18 transcripts were analyzed by members (...) of the research team. Four key themes emerged from the interview data: Working from home, parental engagement, teacher identity, and changes in pedagogy. Each of these themes were discussed in terms of concepts such as engaged pedagogy, agency, self-actualization, recognition and boundary transgression situated in the work of bell hooks. The idea of boundaries wove itself throughout our data as teachers expressed how the transgression of boundaries was occurring in multiple, and often contradictory, ways in pedagogical, professional, institutional and personal spaces and systems. We see in our data evidence of a shift in practice not just in the way teachers are ‘doing’ education but also, perhaps, in the way that teachers are ‘being’ as educators as they adapt to different ways of knowing. This study provides a unique exploration of a time and space in Scotland during 2020. However, the themes and understandings that emerged are of relevance to educators internationally. Schools across the world were impacted by various lockdowns imposed by the Covid-19 pandemic and teachers faced a common set of challenges that were resolved via re-negotiation and recognition of individual and collective agency to create new pedagogies.

Research in school psychologist report writing has argued for reports that connect to the client’s context; have clear links between the referral questions and the answers to these questions; have integrated interpretations; address client strengths and problem areas; have specific, concrete and feasible recommendations; and are adapted to the language and literacy level of the reader. The training of school psychologists involves attention to these factors. However, this paper argues that the experience of aporia, as described by the French philosopher (...) Jacques Derrida, is often removed from the process of report writing, as the aim seems to be to find a formula that works. We call for ethics which is concerned about the good life – this is a broader view than resorting to ethics only when faced with an ethical question. This paper, based on a small qualitative study of seven experienced school psychologists, highlights that psychologists in the process of report writing are caught in the aporia.... (shrink)

We present some striking global consequences of a model quaternionic quantum field theory which is locally complex. We show how making the quaternionic structure a dynamical quantity naturally leads to the prediction of cosmic strings and nonbaryonic hot dark matter candidates.

As a contribution to a wider discussion on moral discernment in theological anthropology, this paper seeks to answer the question “What is the impact of mental illness on an individual’s ability to make moral decisions?” Written from a clinical psychiatric perspective, it considers recent contributions from psychology, neuropsychology and imaging technology. It notes that the popular conception that mental illness necessarily robs an individual of moral responsibility is largely unfounded. Most people who suffer from mental health problems do not lose (...) the capacity to make moral decisions, and mental illness on its own rarely explains anti-social or criminal behaviour. Moreover, the assumptions of some scientists, that recent developments in neuropsychology and brain imaging suggest biological determinism, must be treated with caution. (shrink)

In 1885, during initial discussions of J. C. Maxwell's celebrated thermodynamic demon, Whiting (1) observed that the demon-like velocity selection of molecules can occur in a gravitationally bound gas. Recently, a gravitational Maxwell demon has been proposed which makes use of this observation [D. P. Sheehan, J. Glick, and J. D. Means, Found. Phys. 30, 1227 (2000)]. Here we report on numerical simulations that detail its microscopic phase space structure. Results verify the previously hypothesized mechanism of its paradoxical behavior. This (...) system appears to be the only example of a fully classical mechanical Maxwell demon that has not been resolved in favor of the second law of thermodynamics. (shrink)

We have begun work on two separate but related ontologies for the study of neurological diseases. The first, the Neurological Disease Ontology (ND), is intended to provide a set of controlled, logically connected classes to describe the range of neurological diseases and their associated signs and symptoms, assessments, diagnoses, and interventions that are encountered in the course of clinical practice. ND is built as an extension of the Ontology for General Medical Sciences — a high-level candidate OBO Foundry ontology that (...) provides a set of general classes that can be used to describe general aspects of medical science. ND is being built with classes utilizing both textual and axiomatized definitions that describe and formalize the relations between instances of other classes within the ontology itself as well as to external ontologies such as the Gene Ontology, Cell Ontology, Protein Ontology, and Chemical Entities of Biological Interest. In addition, references to similar or associated terms in external ontologies, vocabularies and terminologies are included when possible. Initial work on ND is focused on the areas of Alzheimer’s and other diseases associated with dementia, multiple sclerosis, and stroke and cerebrovascular disease. Extensions to additional groups of neurological diseases are planned. The second ontology, the Neuro-Psychological Testing Ontology (NPT), is intended to provide a set of classes for the annotation of neuropsychological testing data. The intention of this ontology is to allow for the integration of results from a variety of neuropsychological tests that assay similar measures of cognitive functioning. Neuro-psychological testing is an important component in developing the clinical picture used in the diagnosis of patients with a range of neurological diseases, such as Alzheimer’s disease and multiple sclerosis, and following stroke or traumatic brain injury. NPT is being developed as an extension to the Ontology for Biomedical Investigations. (shrink)

We are developing the Neurological Disease Ontology (ND) to provide a framework to enable representation of aspects of neurological diseases that are relevant to their treatment and study. ND is a representational tool that addresses the need for unambiguous annotation, storage, and retrieval of data associated with the treatment and study of neurological diseases. ND is being developed in compliance with the Open Biomedical Ontology Foundry principles and builds upon the paradigm established by the Ontology for General Medical Science (OGMS) (...) for the representation of entities in the domain of disease and medical practice. Initial applications of ND will include the annotation and analysis of large data sets and patient records for Alzheimer’s disease, multiple sclerosis, and stroke. (shrink)

DNA methylation is a repressive epigenetic mark vital for normal development. Recent studies have uncovered an unexpected role for the DNA methylome in ensuring the correct targeting of the Polycomb repressive complexes throughout the genome. Here, we discuss the implications of these findings for cancer, where DNA methylation patterns are widely reprogrammed. We speculate that cancer‐associated reprogramming of the DNA methylome leads to an altered Polycomb binding landscape, influencing gene expression by multiple modes. As the Polycomb system is responsible for (...) the regulation of genes with key roles in cell fate decisions and cell cycle regulation, DNA methylation induced Polycomb mis‐targeting could directly drive carcinogenesis and disease progression.Editor's suggested further reading in BioEssays Unmasking risk loci: DNA methylation illuminates the biology of cancer predisposition Abstract.
