Subjects and Simulations presents essays focused on suffering and sublimity, representation and subjectivity, and the relation of truth and appearance through engagement with the legacies of Jean Baudrillard and Philippe Lacoue-Labarthe.

In Praise of Philosophy and Other Essays explores Lavelle, Bergson, and Socrates and provides themes from Merleau-Ponty lectures at the Collége de France including “The Problem of Speech” and “Nature and Logos: The Human Body.”.

Sexually signalling animals must trade off the benefits of attracting mates with the consequences of attracting predators. For male guppies, predation risk depends on their behaviour, colouration, environmental conditions and changing intensity of predation throughout the day. Theoretically, this drives diel patterns of display behaviour in native Trinidadian populations, where males display more under low-light conditions when their most dangerous predator is less active. Here, we observed Australian guppies in a laboratory setting to investigate their diel display pattern, and if (...) this pattern is controlled by ambient light intensity. We also quantified individual variation in both the daily frequency and diel pattern of displays, and if such variation relates to body size, colouration and a non-sexual behaviour. Under a typical daily light regime, male guppies displayed mostly in the first hour of observation. Extending the duration of dawn-like lighting, however, resulted in an extended period of high display, demonstrating that light intensity per se is an important cue for this behaviour. These findings mirror those obtained for Trinidadian populations, suggesting that male courtship timing is likely shaped by broad, potentially generalizable features of guppy ecology. The effect of acclimation to captive conditions on male behaviour is also discussed. Whereas the temporal pattern of display appeared consistent, individuals varied in their daily display frequency, and this was correlated with variation in colour phenotype and a measure of non-sexual risk acceptance behaviour. Such relationships pose promising avenues for integrating behavioural and sensory ecology with contemporary work on behavioural syndromes and animal personality. (shrink)

Abstract:This visual essay invites renewed reflection on the iconography of the people. In the spring of 2020, Guatemala's President Alejandro Giammattei prohibited citizens from leaving their homes to help contain the spread of the novel coronavirus known as Covid-19. Doing little to manage the spread of the virus, these curfew events gave new aesthetic and political meaning to a familiar visual genre: photographs of empty streets. For more than a century, and especially in the summer of 2020, images of crowds (...) and mass protests have provided both governments on the one hand, and protesting multitudes on the other with an aesthetic representation of the people. But this interest in collective assemblies has tended to engage only one side of the equation. To fully appreciate the visual power of the people, it is also necessary to understand those images from which people are strikingly absent. (shrink)

The origin of insulin‐expressing β‐cells in the adult mammalian pancreas is controversial. During normal tissue turnover and following injury, β‐cells may be replaced by duplication of existing β‐cells.1 However, an alternative source of β‐cells has recently been proposed based on neogenesis from a Ngn3‐positive population present in regenerating pancreatic ducts.2 The appearance of β‐cells from Ngn3‐positive progenitors is reminiscent of normal pancreas development, and Ngn3‐expressing cells isolated from regenerating pancreas can generate the full repertoire of endocrine phenotypes. The isolation and (...) characterisation of the equivalent human progenitors may represent a significant step forward in the hunt for a cure for diabetes.

Objective: Ethical guidelines are designed to ensure benefits, protection and respect of participants in clinical research. Clinical trials must now be registered on open-access databases and provide details on ethical considerations. This systematic survey aimed to determine the extent to which recently registered clinical trials report the use of standard of care and post-trial obligations in trial registries, and whether trial characteristics vary according to setting. Methods: We selected global randomized trials registered on http://www.clinicaltrials.gov and http://www.controlled-trials.com. We searched for intervention (...) trials of HIV/AIDS, malaria, and tuberculosis from 9 October 2004, the date of the most recent version of the Helsinki Declaration, to 10 April 2007. Results: We collected data from 312 trials. Fifty-eight percent (58%, 95% CI = 53 to 64) of trial protocols report informed consent. Fifty-eight percent (58%, 95% CI = 53 to 64) of trials report active controls. Almost no trials (1%, 95% CI = 0.5 to 3) mention post-trial provisions. Most trials measure surrogate outcomes. Twenty percent (20%, 95% CI = 16 to 25) of trials measure patient-important outcomes, such as death; and the odds that these outcomes are in a low income country are five times greater than for a developed country (odds ratio (OR) 5.03, 95% CI = 2.70 to 9.35, p = < 0.001). Pharmaceutical companies are involved in 28% (CI = 23 to 33) of trials and measure surrogate outcomes more often than nonpharmaceutical companies (OR 2.45, 95% CI = 1.18 to 5.09, p = 0.31). Conclusion: We found a large discrepancy in the quality of reporting and approaches used in trials in developing settings compared to wealthier settings. (shrink)

Daily rhythms in the rate and specificity of protein synthesis occur in most mammalian cells through an interaction between cell‐autonomous circadian regulation and daily cycles of systemic cues. However, the overall protein content of a typical cell changes little over 24 h. For most proteins, translation appears to be coordinated with protein degradation, producing phases of proteomic renewal that maximize energy efficiency while broadly maintaining proteostasis across the solar cycle. We propose that a major function of this temporal compartmentalization—and of (...) circadian rhythmicity in general—is to optimize the energy efficiency of protein synthesis and associated processes such as complex assembly. We further propose that much of this temporal compartmentalization is achieved at the level of translational initiation, such that the translational machinery alternates between distinct translational mechanisms, each using a distinct toolkit of phosphoproteins to preferentially recognize and translate different classes of mRNA.

To hold an environmental ethic is to hold that non-human beings and states of affairs in the natural world have intrinsic value. This seemingly straightforward claim has been the focus of much recent philosophical discussion of environmental issues. Its clarity is, however, illusory. The term ‘intrinsic value’ has a variety of senses and many arguments on environmental ethics suffer from a conflation of these different senses: specimen hunters for the fallacy of equivocation will find rich pickings in the area. This (...) paper is largely the work of the underlabourer. I distinguish different senses of the concept of intrinsic value, and, relatedly, of the claim that non-human beings in the natural world have intrinsic value; I exhibit the logical relations between these claims and examine the distinct motivations for holding them. The paper is not however merely an exercise in conceptual underlabouring. It also defends one substantive thesis: that while it is the case that natural entities have intrinsic value in the strongest sense of the term, i.e., in the sense of value that exists independently of human valuations, such value does not as such entail any obligations on the part of human beings. The defender of nature’s intrinsic value still needs to show that such value contributes to the well-being of human agents. (shrink)

Video ethics in educational research involving children is a recent topic that has arisen since the increase in the use of visual mediums in research especially with the development of new and ubiquitous internet technologies and social media. This paper emerged as an expressed concerned by a group of scholars associated with the new Video Journal of Education and Pedagogy that was established in 2016. The paper is the result of a collective writing process over a period of a few (...) months that discusses visual studies in education and visual ethics in relation to qualitative research in education, and as it applies to children. The article also uses the newly established convention of open review, publishing the results with the paper. (shrink)

William James’s category of “first-hand religion” allows us to arrive at the religious from an internal and individual perspective, including in those activities and phenomena usually considered secular. B. B. King’s 1972 performance at Sing Sing Prison, documented by David Hoffman, brings both the prisoner audience and the performers to an “additional dimension” distinct from the hollowness of everyday (prison) life. In addition, the presence of this intense experience on the YouTube platform creates a fluid community of second-order observers, (...) bound not by any overarching belief but by observation of the experience itself. King’s performance is in the genre of blues music, which, in turn, has associations with African religious traditions. While the study of diverse religious traditions helps inform our understanding of the kinds of activities that might constitute the religious, this study takes individual experience as primary rather than as a manifestation of a particular tradition.
