The 2012 Varsity Medical Debate between Oxford University and Cambridge University provided a stage for representatives from these famous institutions to debate the motion “This house believes that trainee doctors should be able to use the developing world to gain clinical experience.” This article brings together many of the arguments put forward during the debate, centring around three major points of contention: the potential intrinsic wrong of ‘using’ patients in developing countries; the effects on the elective participant; and the effects (...) on the host community. The article goes on to critically appraise overseas elective programmes, offering a number of solutions that would help optimise their effectiveness in the developing world. (shrink)

When an individual facing intractable pain is given an estimate of a few months to live, does hastening death become a viable and legitimate alternative for willing patients? Has the time come for physicians to do away with the traditional notion of healthcare as maintaining or improving physical and mental health, and instead accept their own limitations by facilitating death when requested? The Universities of Oxford and Cambridge held the 2013 Varsity Medical Debate on the motion “This House Would Legalise (...) Assisted Dying”. This article summarises the key arguments developed over the course of the debate. We will explore how assisted dying can affect both the patient and doctor; the nature of consent and limits of autonomy; the effects on society; the viability of a proposed model; and, perhaps most importantly, the potential need for the practice within our current medico-legal framework.

The information contained within the linear sequence of bases (the genome) must be faithfully replicated in each cell cycle, with a balance of constancy and variation taking place over the course of evolution. Recently, it has become clear that additional information important for genetic regulation is contained within the chromatin proteins associated with DNA (the epigenome). Epigenetic information also must be faithfully duplicated in each cell cycle, with a balance of constancy and variation taking place during the course of development (...) to achieve differentiation while maintaining identity within cell lineages. Both the genome and the epigenome are synthesized at the replication fork, so the events occurring during S‐phase provide a critical window of opportunity for eliciting change or maintaining existing genetic states. Cells discriminate between different states of chromatin through the activities of proteins that selectively modify the structure of chromatin. Several recent studies report the localization of certain chromatin modifying proteins to replication forks at specific times during S‐phase. Since transcriptionally active and inactive chromosome domains generally replicate at different times during S‐phase, this spatiotemporal regulation of chromatin assembly proteins may be an integral part of epigenetic inheritance.

Frequent public uproar over forms of data science that rely on information about people demonstrates the challenges of defining and demonstrating trustworthy digital data research practices. This paper reviews problems of trustworthiness in what we term pervasive data research: scholarship that relies on the rich information generated about people through digital interaction. We highlight the entwined problems of participant unawareness of such research and the relationship of pervasive data research to corporate datafication and surveillance. We suggest a way forward by (...) drawing from the history of a different methodological approach in which researchers have struggled with trustworthy practice: ethnography. To grapple with the colonial legacy of their methods, ethnographers have developed analytic lenses and researcher practices that foreground relations of awareness and power. These lenses are inspiring but also challenging for pervasive data research, given the flattening of contexts inherent in digital data collection. We propose ways that pervasive data researchers can incorporate reflection on awareness and power within their research to support the development of trustworthy data science. (shrink)

Why does symbolic communication in humans develop primarily in an oral medium, and how do theories of language origin explain this? Non-human primates, despite their ability to learn and use symbolic signs, do not develop symbols as in oral language. This partly owes to the lack of a direct cortico-motoneuron control of vocalizations in these species compared to humans. Yet such modality-related factors that can impinge on the rise of symbolic language are interpreted differently in two types of evolutionary storylines. (...) 1) Some theories posit that symbolic language originated in a gestural modality, as in “sign languages”. However, this overlooks work on emerging sign and spoken language showing that gestures and speech shape signs differently. 2) In modality-dependent theories, some emphasize the role of iconic sounds, though these lack the efficiency of arbitrary symbols. Other theorists suggest that ontogenesis serves to identify human-specific mechanisms underlying an evolutionary shift from pitch varying to orally-modulated vocalizations (babble). This shift creates numerous oral features that can support efficient symbolic associations. We illustrate this principle using a sound-picture association task with 40 learners who hear words in an unfamiliar language (Mandarin) with and without a filtering of oral features. Symbolic associations arise more rapidly and accurately for sounds containing oral features compared to sounds bearing only pitch features, an effect also reported in experiments with infants. The results imply that, beyond a competence to learn and use symbols, the rise of symbolic language rests on the types of signs that a modality of expression affords. (shrink)

Behavior, language, development, identity, and science—all of these phenomena are commonly characterized as 'social' in nature. But what does it mean to be 'social'? Is there any intrinsic 'mark' of the social shared by these phenomena? In the first book to shed light on this foundational question, twelve distinguished philosophers and social scientists from several disciplines debate the mark of the social. Their varied answers will be of interest to sociologists, anthropologists, philosophers, psychologists, and anyone interested in the theoretical foundations (...) of the social sciences. (shrink)

The idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics (...) that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probablyin lieuof robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS. (shrink)

While new generations of implantable brain computer interface devices are being developed, evidence in the literature about their impact on the patient experience is lagging. In this article, we address this knowledge gap by analysing data from the first-in-human clinical trial to study patients with implanted BCI advisory devices. We explored perceptions of self-change across six patients who volunteered to be implanted with artificially intelligent BCI devices. We used qualitative methodological tools grounded in phenomenology to conduct in-depth, semi-structured interviews. Results (...) show that, on the one hand, BCIs can positively increase a sense of the self and control; on the other hand, they can induce radical distress, feelings of loss of control, and a rupture of patient identity. We conclude by offering suggestions for the proactive creation of preparedness protocols specific to intelligent—predictive and advisory—BCI technologies essential to prevent potential iatrogenic harms.

ABSTRACTThe question of how to engage with stakeholders in situations of value conflict to create value that includes a plurality of conflicting stakeholder value perspectives represents one of the crucial current challenges of stakeholder engagement as well as of value creation stakeholder theory. To address this challenge, we conceptualize a discursive sharing process between affected stakeholders that is oriented toward discursive justification involving multiple procedural steps. This sharing process provides procedural guidance for firms and stakeholders to create pluralistic stakeholder value (...) through the discursive accommodation of diverging stakeholder value perspectives. The outcomes of such a discursive value-sharing process range from stakeholder value dissensus to low and increasing levels of stakeholder value congruence to stakeholder value consensus. Hence, this article contributes to the emerging literature on integrative stakeholder engagement by conceptualizing a procedural framework that is neither overly oriented towards dissensus nor consensus.

Spatial and temporal heterogeneity are often described as important factors having a strong impact on biodiversity. The effect of heterogeneity is in most cases analyzed by the response of biotic interactions such as competition of predation. It may also modify intrinsic population properties such as growth rate. Most of the studies are theoretic since it is often difficult to manipulate spatial heterogeneity in practice. Despite the large number of studies dealing with this topics, it is still difficult to understand how (...) the heterogeneity affects populations dynamics. On the basis of a very simple model, this paper aims to explicitly provide a simple mechanism which can explain why spatial heterogeneity may be a favorable factor for production. We consider a two patch model and a logistic growth is assumed on each patch. A general condition on the migration rates and the local subpopulation growth rates is provided under which the total carrying capacity is higher than the sum of the local carrying capacities, which is not intuitive. As we illustrate, this result is robust under stochastic perturbations. (shrink)

Si, apres tout, les logiciens, et meme les philosophes, peuvent dire des choses sensees, alors il est possible que certains logiciens, et meme des philosophes du passe, y compris d'un passe lointain, aient dit parfois, meme si certaines lumieres leur faisaient defaut, des choses sensees. Cet hommage mesure, rendu par Ryle au passe, donne ici lieu a une brillante fantaisie sur la vie de Platon ou les faits ne cessent de repondre aux raisons, comme dans un roman anglais. Mais le (...) motif est tres serieux: la vie d'un philosophe devrait aller comme sa pensee, du plus obscur au plus clair. Las! Dans l'itineraire de Platon les faits furent les plus forts. Il faut donc secouer l'image traditionnelle de sa vie et de sa philosophie et reprendre toute la chronologie des Dialogues. A sa maniere, Ryle nous offre une meditation sur les commencements de la philosophie. (shrink)

During human-human interaction, emotion plays a vital role in structuring dialogue. Emotional content drives features such as topic shift, lexicalisation change and timing; it affects the delicate balance between goals related to the task at hand and those of social interaction; and it represents one type of feedback on the effect that utterances are having. These various facets are so central to most real-world interaction, that it is reasonable to suppose that emotion should also play an important role in human-computer (...) interaction. To that end, techniques for detecting, modelling, and responding appropriately to emotion are explored, and an architecture for bringing these techniques together into a coherent system is presented.

Postmortem evidence of chronic traumatic encephalopathy (CTE) in the brains of American National Football League players who suffered concussions while playing have intensified concerns about the risks of concussion in sport.1 Concussions are frequently sustained by amateur and professional players of Australia’s three most popular football codes (Australian football, rugby league, and rugby union) and, to a lesser extent, other contact sports such as soccer. This raises major concerns about possible long-term neurological damage, cognitive impairment and mental health problems in (...) players of these sports. (shrink)
