Most countries compile evidence from witnesses and victims manually, whereby the interviewer assimilates what the interviewee says during the course of an interview to produce an evidential statement. This exploratory research examined the quality of evidential statements generated in real world investigations. Transcribed witness/victim interviews were compared to the resultant written statements produced by the interviewing officer and signed as an accurate record by the interviewee. A coding protocol was devised to assess the consistency of information between what was said (...) by the interviewee in the verbal interview and what was reported in the written statement. Statements contained numerous errors including omissions, distortions, and the inclusion of information not mentioned in the verbal interview. This exploratory work highlights an important area for future research focus. (shrink)

ArgumentA plagiarism charge in 1827 sparked a public controversy centered between Jean-Victor Poncelet (1788–1867) and Joseph-Diez Gergonne (1771–1859) over the origin and applications of the principle of duality in geometry. Over the next three years and through the pages of various journals, monographs, letters, reviews, reports, and footnotes, vitriol between the antagonists increased as their potential publicity grew. While the historical literature offers valuable resources toward understanding the development, content, and applications of geometric duality, the hostile nature of the exchange (...) seems to have deterred an in-depth textual study of the explicitly polemical writings. We argue that the necessary collective endeavor of beginning and ending this controversy constitutes a case study in the circulation of geometry. In particular, we consider how the duality controversy functioned as a medium of communicating new fundamental principles to a wider audience of practitioners. (shrink)

In their publications during the 1820s, Jakob Steiner and Julius Plücker frequently derived the same results while claiming different methods. This paper focuses on two such results in order to compare their approaches to constructing figures, calculating with symbols, and representing geometric magnitudes. Underlying the repetitive display of similar problems and theorems, Steiner and Plücker redefined synthetic and analytic methods in distinctly personal practices.

A History of Mathematics: From Mesopotamia to Modernity covers the evolution of mathematics through time and across the major Eastern and Western civilizations. It begins in Babylon, then describes the trials and tribulations of the Greek mathematicians. The important, and often neglected, influence of both Chinese and Islamic mathematics is covered in detail, placing the description of early Western mathematics in a global context. The book concludes with modern mathematics, covering recent developments such as the advent of the computer, chaos (...) theory, topology, mathematical physics, and the solution of Fermat's Last Theorem. Containing more than 100 illustrations and figures, this text, aimed at advanced undergraduates and postgraduates, addresses the methods and challenges associated with studying the history of mathematics. The reader is introduced to the leading figures in the history of mathematics and their fields. An extensive bibliography with cross-references to key texts will provide invaluable resource to students and exercises will stretch the more advanced reader. (shrink)

Different animal groups exhibit a surprisingly diversity of sex determination systems. Moreover, even systems that are superficially similar may utilize different underlying mechanisms. This diversity is illustrated by a comparison of sex determination in three well‐studied model organisms: the fruitfly Drosophila melanogaster, the nematode Caenorhabditis elegans, and the mouse. All three animals exhibit male heterogamety, extensive sexual dimorphism and sex chromosome dosage compensation, yet the molecular and cellular processes involved are now known to be quite unrelated. The similarities must have (...) arisen by convergent evolution. Studies of sex determination demonstrate that evolution can produce a variety of solutions to the same basic problems in development.

A relational, feminist ethics of pregnancy sees the fetus as valuable both relationally and biologically, rather than minimized or ignored. Women are always at the center of ethical concern. To avoid gender-based discrimination, women’s bodily integrity, consent (to pregnancy), and physical “nestedness” (containment of the fetus within a person’s body) must be considered primary ethical concerns. This relational approach accounts for the significance of pregnancy and the grief of pregnancy loss while concurrently providing an ethical justification for abortion. This refined (...) framework has significant benefits because it can address a spectrum of ethical issues that arise around pregnancy. (shrink)

In February 2020, the British Society for the History of Science hosted its first entirely digital conference via Twitter, with the dual goals of improving outreach and engagement with international historians of science, and exploring methods of reducing the carbon footprint of academic activities. In this article we discuss how we planned and organized this conference, and provide a summary of our experience of the conference itself. We also describe in greater detail the motivations behind its organization, and explore the (...) good and bad dimensions of this relatively new kind of conferencing. As the climate crisis becomes more acute and, in turn, the pressure to reduce the carbon footprint of academic activities increases, we argue that digital conferences of this style will necessarily become more central to how academia operates. By sharing our own experiences of running such a conference, we seek to contribute to a rapidly growing body of knowledge on the subject that might be drawn on to improve our practices going forward. We also share some of our own ideas about how best to approach digital conference organization which helped us to make the most of this particular event. (shrink)

Charlotte Angas Scott (1858–1932) was an internationally renowned geometer, the first British woman to earn a doctorate in mathematics, and the chair of the Bryn Mawr mathematics department for forty years. There she helped shape the burgeoning mathematics community in the United States. Scott often motivated her research as providing a “geometric treatment” of results that had previously been derived algebraically. The adjective “geometric” likely entailed many things for Scott, from her careful illustration of diagrams to her choice of references (...) and citations. This article will focus on Scott’s striking and consistent use of geometric to describe a reality of dynamic points, lines, planes, and spaces that could be manipulated analogously to physical objects. By providing geometric interpretations of algebraic derivations, Scott committed to an early-nineteenth-century aesthetic vision of a “whole” analytical geometry that she adapted to modern research areas.

This article proposes a semiotic reading of the most widely recognized internet image macro memes (termed “canonical image macro memes” or CIMMs) and analyzes these memes as individual texts. It demonstrates that memes possess their own language, or system of signs, and form their own literature. By delineating the extent to which the visual and verbal components are customizeable image macro memes, this article strives to understand the language of CIMMs, and the processes and limitations by which meaning is generated. (...) Understanding each meme as a text, this analysis demonstrates that the first-order semiological system of memes is informed and underpinned by a discrete, highly specific second-order semiological system, which guides the way in which a meme user will read memetic texts both individually and in relation to one another, and which must be analyzed as a phenomenon unto itself. The increasingly complex interreferentiality found within the growing corpus of memetic texts engenders sets of memes which only acquire signification when read together; a consideration of such memes demonstrates the codification of a metalanguage, or mythology, of memes, which allows us to understand better how memes have begun to consolidate their own canon.

Open Court began publishingThe Monistin 1890 as a journal“devotedto the philosophy of science”that regularly included mathematics. The audiencewas understood to be“cultured people who have not a technical mathematicaltraining”but nevertheless“have a mathematical penchant.”With these constraints,the mathematical content varied from recreations to logical foundations, but every-one had something to say about non-Euclidean geometry, in debates that rangedfrom psychology to semantics.

Pet-directed speech (PDS) is often produced by humans when addressing dogs. Similar to infant-directed speech, PDS is marked by a relatively higher and more modulated fundamental frequency (f 0) than is adult-directed speech. We tested the prediction that increasing eye size in dogs, one facial feature of neoteny (juvenilisation), would elicit exaggerated prosodic qualities or pet-directed speech. We experimentally manipulated eye size in photographs of twelve dog breeds by −15%, +15% and +30%. We first showed that dogs with larger eyes (...) were indeed perceived as younger. We then recorded men and women speaking towards these photographs, who also rated these images for cuteness. Linear mixed-effects models demonstrated that increasing eye size by 15% significantly increased pitch range (f 0 range) and variability (f 0CV) among women only. Cuteness ratings did not vary with eye size, due to a possible ceiling effect across eye sizes. Our results offer preliminary evidence that large eyes can elicit pet-directed speech and suggest that PDS may be modulated by perceived juvenility rather than cuteness. We discuss these findings in the context of inter-species vocal communication. (shrink)

As mathematics departments in the United States began to shift toward standards of original research at the end of the nineteenth century, many adopted journal clubs as forums to engage with new periodical literature. The Bryn Mawr Mathematics Journal Club, maintained episodically between 1896 and 1924, began as a supplement to the graduate course offerings. Each semester student and professor participants focused on a single disciplinary area or surveyed what had been published lately. The Notebooks containing these reports were stored (...) on the open shelves of the college library. These collectively composed documents record ways in which graduate students transcribed and interpreted contemporary literature from the front to the back of mathematics. This article will consider the entries of a single student in which published mathematics was rewritten for a local audience and how the process of relocation animated research at Bryn Mawr.

Lesbian, gay, bisexual, trans and/or queer (LGBTQ) people experience profound health and social care inequalities. Research suggests that staff with negative attitudes towards LGBTQ people, are more likely to hold strong, traditional, religious beliefs. This article reports on a single case study with a newly qualified UK nurse who has since left the National Health Service. This is based on a single interview taken from a larger dataset derived from a funded scoping research study exploring religious freedoms, sexual orientation and (...) gender identity rights in older age care spaces. The interviewee described a toxic nursing culture on a hospital ward for older people. She recounted various incidents involving homophobic and transphobic practice and LGBTQ microaggressions which reportedly impacted the quality of nursing care. The findings are considered in relation to standards for anti-oppressive practice in nursing care, and how nursing students and staff can be supported in addressing practice relating to equality and diversity issues, specifically LGBTQ issues. They confirm the direct significance of addressing the needs and circumstances of LGBTQ people in nursing curricula and ongoing professional practice, and the need to further research, evaluate and progress translation of learning into improved quality care for diverse populations.

In this article I consider the role of passing and performance in the everyday lives of alkaptonuria and vitiligo patients. Race, LGBTQ, gender and disability scholars have long used the term passing to describe sub-groups of people within marginal populations who intentionally manipulate their bodies or alter their behaviour in order to claim identities that are not socially assigned to them at birth. In this paper I demonstrate the effectiveness of the passing strategies that patients use in order to mitigate (...) their disease symptoms and render them invisible, thus enabling them to pass as “healthy” or unaffected by their condition. I further consider how patients who choose not to pass utilise resistance strategies in order to generate awareness of their disease and encourage funding for it. I conclude by assessing the effectiveness of these strategies in determining whether or not patients can pass, and the ways in which this is aided or hindered by their social and economic status.

This article explores how ‘fat shaming’ as a practice that encourages open disdain for those living in larger bodies operates as a moralising tool to regulate and manage those who are viewed as ‘bad citizens’. It begins by outlining the problematic use of fat shaming language that is often used as a tool to promote ‘healthy’ lifestyle choices by those who view it as not only an acceptable way of communicating the health risks associated with obesity, but also a productive (...) way of motivating people with overweight and obesity to lose weight. I then go on to discuss how shame as it relates to body image and excess weight is culturally produced through both objective conceptualisations of deviance and subjective judgements about the moral character of those who are living with excess weight. Adopting a feminist theoretical perspective, this article further considers the reciprocal nature of fat shaming by calling attention to how shame as a felt emotion is dependent on understandings of oneself in relation to others, as well as the relationships that one forms with others. In this way, I argue that shame in general, and fat shaming in particular, is performative to the extent that it exists as a relational construct that is iteratively produced through the language and actions that give it meaning.

In this series of eight articles, the Australian Traumatic Brain Injury Initiative (AUS-TBI) consortium describes the Australian approach used to select the common data elements collected acutely that have been shown to predict outcome following moderate-severe traumatic brain injury (TBI) across the lifespan. This article presents the unified single data dictionary, together with additional measures chosen to facilitate comparative effectiveness research and data linkage. Consultations with the AUS-TBI Lived Experience Expert Group provided insights on the merits and considerations regarding data (...) elements for some of the study areas, as well as more general principles to guide the collection of data and the selection of meaningful measures. These are presented as a series of guiding principles and themes. The AUS-TBI Aboriginal and Torres Strait Islander Advisory Group identified a number of key points and considerations for the project approach specific to Aboriginal and Torres Strait Islander peoples, including key issues of data sovereignty and community involvement. These are outlined in the form of principles to guide selection of appropriate methodologies, data management, and governance. Implementation of the AUS-TBI approach aims to maximize ongoing data collection and linkage, to facilitate personalization of care and improved outcomes for people who experience moderate-severe TBI.

It is a cliché of self-help advice that there are no problems, only opportunities. The rationale and actions of the BSHS in creating its Global Digital History of Science Festival may be a rare genuine confirmation of this mantra. The global COVID-19 pandemic of 2020 meant that the society's usual annual conference – like everyone else's – had to be cancelled. Once the society decided to go digital, we had a hundred days to organize and deliver our first online festival. (...) In the hope that this will help, inspire and warn colleagues around the world who are also trying to move online, we here detail the considerations, conversations and thinking behind the organizing team's decisions.

Anhedonia, or a deficit in the liking, wanting, and seeking of rewards, is typically assessed via self-reported “in-the-moment” emotional and motivational responses to reward stimuli and activities. Given that mental imagery is known to evoke emotion and motivational responses, we conducted two studies to investigate the relationship between mental imagery use and self-reported anhedonia. Using a novel Reward Response Scale (adapted from the Dimensional Anhedonia Rating Scale, DARS; Rizvi et al., Citation2015) modified to assess deliberate and spontaneous mental imagery use, (...) Study 1 (N = 394) compared uninstructed and instructed mental imagery use, and Study 2 (N = 586) conducted a test of replication of uninstructed mental imagery use. Results showed that greater mental imagery use was associated with higher reward response scores (Study 1 & 2), and this relationship was not moderated by whether imagery use was uninstructed or instructed (Study 1). Importantly, mental imagery use moderated the convergence between reward response and depression scale measures of anhedonia, with lower convergence for those reporting higher mental imagery use (Study 1 & 2). Results suggest that higher spontaneous mental imagery use may increase self-reported reward response and reduce the convergence between reward response scale and depression questionnaire measures of anhedonia.

In Australia, young adults are more likely to experience psychological distress than other age-groups. Accordingly, volunteer work engagement may act as an important tool for supporting psychological wellbeing. The present study relies on the job demands–resources model and self-determination theory to help understand the negative consequences of high work demands and the importance of effective organizational support to enhance positive mental health outcomes. To address research gaps, the current study explores these concepts for the young adulthood cohort in not-for-profit organizations. (...) The study aims to explore the relationship between psychological wellbeing, volunteer work engagement, and perceived organizational support. The study used a quantitative, cross-lagged, longitudinal method for collecting data from two online surveys completed 4 weeks apart. The inclusion criteria of participants were volunteers who worked a minimum of 4 h a month, resided in Australia, and were between 19 and 40 years old. The main study findings were that perceived organizational support mediated the relationship between psychological wellbeing at time point 1 and volunteer engagement at time point 2. However, perceived organizational support did not mediate volunteer engagement at time point 1 and psychological wellbeing at time point 2. There were no bidirectional effects between volunteer engagement and psychological wellbeing. The findings contributed to the existing literature, suggesting there are overlaps between support mechanisms and motivation between paid and unpaid work. The practical implications for not-for-profit organizations are the importance of providing organizational support for young adult volunteers to improve wellbeing outcomes. Limitations and future study recommendations are presented. (shrink)

I claim that the Hodgkin‐Huxley (HH) current equations owe a great deal of their importance to their role in bringing results from experiments on squid giant action preparations to bear on the study of the action potential in other neurons in other in vitro and in vivo environments. I consider ideas from Weber and Craver about the role of Coulomb’s and other fundamental equations in explaining the action potential and in HH’s development of their equations. Also, I offer an embellishment (...) to Schaffner’s emergent unifier conception of the HH model. †To contact the author, please write to: Department of HPS, University of Pittsburgh, 1017 Cathedral of Learning, Pittsburgh, PA 15260; e‐mail: [email protected].

Alan Hodgkin’s and Andrew Huxley’s mid-20th century work on the ionic currents generating neuron action potentials stands among that century’s great scientific achievements. Unsurprisingly, that case has attracted widespread attention from neuroscientists, historians and philosophers of science. In this paper, I do not propose to add any new insights into the vast historical treatment of Hodgkin’s and Huxley’s scientific discoveries in that much- discussed episode. Instead, I focus on an aspect of it that hasn’t received much attention: Hodgkin’s and Huxley’s (...) own assessments about what their famous “quantitative description” accomplished. The “Hodgkin-Huxley model” is now widely recognized as a foundation of contemporary computational neuroscience. Yet Hodgkin and Huxley expressed serious caveats about their model and what it added to their scientific discoveries, as far back as their (1952d), in which they first presented their model. They were even more critical of its accomplishments in their Nobel Prize addresses a decade later. Most notably, as I argue here, some worries they raised about their quantitative description seem still to be relevant to current work in ongoing computational neuroscience. (shrink)
