What enables individually simple insects like ants to act with such precision and purpose as a group? How do trillions of individual neurons produce something as extraordinarily complex as consciousness? What is it that guides self-organizing structures like the immune system, the World Wide Web, the global economy, and the human genome? These are just a few of the fascinating and elusive questions that the science of complexity seeks to answer. In this remarkably accessible and companionable book, leading complex systems (...) scientist Melanie Mitchell provides an intimate, detailed tour of the sciences of complexity, a broad set of efforts that seek to explain how large-scale complex, organized, and adaptive behavior can emerge from simple interactions among myriad individuals. Comprehending such systems requires a wholly new approach, one that goes beyond traditional scientific reductionism and that re-maps long-standing disciplinary boundaries. Based on her work at the Santa Fe Institute and drawing on its interdisciplinary strategies, Mitchell brings clarity to the workings of complexity across a broad range of biological, technological, and social phenomena, seeking out the general principles or laws that apply to all of them. She explores as well the relationship between complexity and evolution, artificial intelligence, computation, genetics, information processing, and many other fields. Richly illustrated and vividly written, Complexity : A Guided Tour offers a comprehensive and eminently comprehensible overview of the ideas underlying complex systems science, the current research at the forefront of this field, and the prospects for the field's contribution to solving some of the most important scientific questions of our time.

In recent decades, evidence-based medicine has become one of the foundations of clinical practice, making it necessary that healthcare practitioners develop keen critical appraisal skills for scientific papers. Worksheets to guide clinicians through this critical appraisal are often used in journal clubs, a key part of continuing medical education. A similar need is arising for health professionals to develop skills in the critical appraisal of medical ethics papers. Medicine is increasingly ethically complex, and there is a growing medical ethics literature (...) that modern practitioners need to be able to use in their practice. In addition, clinical ethics services are commonplace in healthcare institutions, and the lion’s share of the work done by these services is done by clinicians in addition to their usual roles. Education to support this work is important. In this paper, we present a worksheet designed to help busy healthcare practitioners critically appraise ethics papers relevant to clinical practice. In the first section, we explain what is different about ethics papers. We then describe how to work through the steps in our critical appraisal worksheet: identifying the point at issue; scrutinising definitions; dissecting the arguments presented; considering counterarguments; and finally deciding on relevance. Working through this reflective worksheet will help healthcare practitioners to use the ethics literature effectively in clinical practice. We also intend it to be a shared evaluative tool that can form the basis of professional discussion such as at ethics journal clubs. Practising these critical reasoning skills will also increase practitioners’ capacity to think through difficult ethical decisions in daily clinical practice. (shrink)

Sketching as a scientific practice goes beyond the simple act of inscribing diagrams onto paper. Scientists produce a wide range of representations through sketching, as it is tightly coupled to model-based reasoning. Chemists in particular make extensive use of sketches to reason about chemical phenomena and to communicate their ideas. However, the chemical sciences have a unique problem in that chemists deal with the unseen world of the atomic-molecular level. Using sketches, chemists strive to develop causal mechanisms that emerge from (...) the structure and behavior of molecular-level entities, to explain observations of the macroscopic visible world. Interpreting these representations and constructing sketches of molecular-level processes is a crucial component of student learning in the modern chemistry classroom. Sketches also serve as an important component of assessment in the chemistry classroom as student sketches give insight into developing mental models, which allows instructors to observe how students are thinking about a process. In this paper we discuss how sketching can be used to promote such model-based reasoning in chemistry and discuss two case studies of curricular projects, CLUE and The Connected Chemistry Curriculum, that have demonstrated a benefit of this approach. We show how sketching activities can be centrally integrated into classroom norms to promote model-based reasoning both with and without component visualizations. Importantly, each of these projects deploys sketching in support of other types of inquiry activities, such as making predictions or depicting models to support a claim; sketching is not an isolated activity but is used as a tool to support model-based reasoning in the discipline.

“Aesthetics” is not a concern that figures prominently in Isabelle Stengers’s work and it is not difficult to find the reasons why. Reading the discipline of aesthetics through a historical and systematic perspective derived from Stengers and Alfred North Whitehead, the invention of modern aesthetics as a philosophical discipline in the 18th century can be read as the flipside to “the invention of modern science” described by Stengers in her seminal book with just this title. Understood in this historical sense (...) as the philosophical discipline founded by Alexander Gottlieb Baumgarten and Immanuel Kant, aesthetics instills and cements what Alfred North Whitehead termed “the bifurcation of nature,” the implicit...

How does the body influence the way we see the world? _Imagination, Illness and Injury_ examines the psychological factors behind perceptual limitations and distortions and links a broad range of somatic manifestations with their resolution. Melanie Starr Costello applies Jungian theory to a variety of cases, attributing psychosomatic phenomena to cognitive processes that are common to us all. She analyses the role of illness in several life narratives, and interprets the appearance of somatic phenomena during important phases of analytic (...) treatment. Together these case narratives present a significant challenge to established views of psychosomatics. Subjects covered include: archetypal constrictions of identity somatic elements of perception the psyche-soma split. _Imagination, Illness and Injury _brings a fresh perspective to the understanding and treatment of the psychotherapy client as a psycho-somatic unity. Jungian analysts, psychoanalysts, and psychotherapists will greatly benefit from the clinical applications of archetypal theory presented here. (shrink)

Given the profound influence of social media and emerging evidence of its effects on human behavior and health, bioethicists have an important role to play in the development of professional standards of conduct for health professionals using social media and in the design of online systems themselves. In short, social media is a bioethics issue that has serious implications for medical practice, research, and public health. Here, we inventory several ethical issues across four areas at the intersection of social media (...) and health: the impact of social networking sites on the doctor‐patient relationship, the development of e‐health platforms to deliver care, the use of online data and algorithms to inform health research, and the broader public health consequences of widespread social media use. In doing so, we review discussions of these topics and emphasize the need for bioethics to focus more deeply on the ways online technology platforms are designed and implemented. We argue that bioethicists should turn their attention to the ways in which consumer engagement, bias, and profit maximization shape online content and, consequently, human behavior and health. We also offer a set of recommendations and suggest future directions for addressing ethical challenges in these domains. (shrink)

The human pathogen Vibrio cholerae exhibits two distinct lifestyles: one in the aquatic environment where it often associates with chitinous surfaces and the other as the causative agent of the disease cholera. While much of the research on V. cholerae has focused on the host‐pathogen interaction, knowledge about the environmental lifestyle of the pathogen remains limited. We recently showed that the polymer chitin, which is extremely abundant in aquatic environments, induces natural competence as a mode of horizontal gene transfer and (...) that this competence regulon also includes the type VI secretion system (T6SS), a molecular killing device. Here, I discuss the putative consequences that chitin‐induced T6SS activation could have on intestinal colonization and how the transmission route might influence disease outcome. Moreover, I propose that common infant animal models for cholera might not sufficiently take into account T6SS‐mediated interbacterial warfare between V. cholerae and the intestinal microbiota.

Once upon a time, there was a consensus in this country that the welfare state was the jewel in the crown of the post-war settlement. It was a national badge of moral worth. It was held to embody certain virtues that people told themselves were the hallmark of a civilised society: altruism, equity, dignity, fellowship. It defined Britain as a co-operative exercise which bound us together into a cohesive society. Or so we told ourselves.

This article contributes to debates on the relationship between waste and value by exploring how the revaluation of waste at a dump in Soweto, South Africa, was transformed during the 2008 economic crisis. It critically engages Herod, Pickren, Rainnie & McGrath-Champ’s differentiation between ‘devalorisation’ due to material degradation and ‘devaluation’ due to prices being too low for recycling to be profitable, in order to develop three arguments. First, it is necessary to recognise how political mobilisation by reclaimers shapes the conditions (...) for devaluation by affecting local prices for recyclables. Second, reclaimers’ struggles to monopolise control over waste as they govern their labour process may lead to materials that could be profitably reclaimed remaining wasted. Third, waste is not only revalued through global production networks. Analysing why reclaimers choose to revalue waste through either formal or informal circuits provides insights into how the economy is constituted and affected by crisis in postcolonial contexts.

Melanie Sarzano | : In this paper, I compare cases of self-deception and cases of pragmatic encroachment and argue that confronting these cases generates a dilemma about rationality. This dilemma turns on the idea that subjects are motivated to avoid costly false beliefs, and that both cases of self-deception and cases of pragmatic encroachment are caused by an interest to avoid forming costly false beliefs. Even though both types of cases can be explained by the same belief-formation mechanism, only (...) self-deceptive beliefs are irrational: the subjects depicted in high-stakes cases typically used in debates on pragmatic encroachment are, on the contrary, rational. If we find ourselves drawn to this dilemma, we are forced either to accept—against most views presented in the literature—that self-deception is rational or to accept that pragmatic encroachment is irrational. Assuming that both conclusions are undesirable, I argue that this dilemma can be solved. In order to solve this dilemma, I suggest and review several hypotheses aimed at explaining the difference in rationality between the two types of cases, the result of which being that the irrationality of self-deceptive beliefs does not entirely depend on their being formed via a motivationally biased process. | : Dans cet article, je compare les cas classiques de duperie de soi aux cas que l’on trouve dans les débats sur la question de l’empiètement pragmatique et défends l’idée selon laquelle ces deux types de cas peuvent être compris comme étant produits par un même mécanisme visant à éviter la formation de croyances fausses coûteuses. Cette comparaison nous mène naturellement à former un dilemme à propos de la rationalité des croyances. Le dilemme repose sur l’idée que bien que ce mécanisme mène à la formation de croyances irrationnelles dans les cas de duperie de soi, il ne semble pas affecter la rationa-lité du sujet dans les cas d’empiètement pragmatique : alors que les sujets autodupés sont irrationnels, les sujets décrits dans les cas d’empiètement pragmatique ne le sont pas. Pour résoudre ce dilemme sans rejeter les présupposés selon lesquels les croyances issues de la duperie de soi sont irrationnelles et que les cas sur lesquels repose l’empiètement pragmatique sont rationnels, je propose plusieurs hypothèses visant à expliquer cette différence, prouvant ainsi que ce dilemme n’est qu’apparent et que l’irrationalité de la duperie de soi ne peut uniquement dépendre de ce mécanisme sous l’influence de considérations pratiques.

Our exploratory study considers whether the internal audit function is an efficient “third line of defense” for risk management and control as proposed by The Institute of Internal Auditors. To that end, we interview chief audit executives and experienced internal auditors to examine whether CAEs manage the impressions of audit committee members in the annual accountability process. We also provide an illustration of impression management techniques through a documentary case that explores a unique and exclusive dataset consisting of the main (...) guidance, framework, and accountability documents of one of these organizations. Our analysis highlights how several macro- and microimpression management techniques were used to burnish the image of internal auditors and, more importantly, the management team. Rather than monitoring managers, the CAEs team up with them. Our findings cast doubts on the conceptualization of internal audit as the independent third line of defense envisioned to be a keystone of the governance mosaic. This study supports other research that questions the effectiveness of internal auditing as a governance mechanism. It also contributes to the impression management literature by exposing impression management practices that occur through a private reporting channel—the internal audit function’s annual accountability to the audit committee. Last but not least, significant ethical concerns are raised in regard to internal audit, and research is urged in that area. (shrink)

Responding to climate change and avoiding irreversible climate tipping points requires radical and drastic action by 2030. This urgency raises serious questions for energy companies, one of the world’s largest emitters of greenhouse gases (GHGs), in terms of how they frame, and reframe, their response to climate change. Despite the majority of energy companies releasing ambitious statements declaring net zero carbon ambitions, this ‘talk’ has not been matched with sufficient urgency or substantive climate action. To unpack the disconnect between talk (...) and action, this paper draws on the literature on framing, organisational hypocrisy, and collective moral responsibility. We conduct a longitudinal qualitative content analysis of the framing of climate change used by the ten largest European investor-owned energy companies and the actions they have taken to shift their business practices. Our findings reveal three main categories of energy companies: (i) deflecting, (ii) stagnating, and (iii) evolving. We show key differences in the relationship between framing and action over time for each category, revealing how deflecting companies have larger and persistent gaps between green talk and concrete action and how stagnating companies are delaying action despite increased green talk, while evolving companies exhibit a closer link between talk and action that tends to be realised over time. Our analysis reveals how competing approaches to framing collective moral responsibility help understand the trajectories of talk and action across the different categories of energy companies. This research makes several contributions to the literature on organisational hypocrisy and collective moral responsibility in the context of climate change. Our analysis highlights the complex relationship between collective moral responsibility, organisational hypocrisy and climate action, revealing how different collective framings—diffuse, teleological, or agential—can both enable and offset substantive climate action. The study also enriches our understanding of the performative nature of collective moral responsibility by examining its temporal dimensions and showing how an agential, backward-looking focus is associated with more meaningful climate action.

Matrix models are widely used in biology to predict the temporal evolution of stage-structured populations. One issue related to matrix models that is often disregarded is the sampling variability. As the sample used to estimate the vital rates of the models are of finite size, a sampling error is attached to parameter estimation, which has in turn repercussions on all the predictions of the model. In this study, we address the question of building confidence bounds around the predictions of matrix (...) models due to sampling variability. We focus on a density-dependent Usher model, the maximum likelihood estimator of parameters, and the predicted stationary stage vector. The asymptotic distribution of the stationary stage vector is specified, assuming that the parameters of the model remain in a set of the parameter space where the model admits one unique equilibrium point. Tests for density-dependence are also incidentally provided. The model is applied to a tropical rain forest in French Guiana. (shrink)

We examine the relation between worker substance abuse and workplace fraud in a sample of medical doctors. Relative to their peers, we observe that doctors engaging in substance abuse are between 50 and 100 times more likely to commit fraud in a given year. This result is consistent with research suggesting that substance abuse both creates financial pressures and impairs the functioning of cognitive self-regulatory mechanisms. Our results are robust in within-subject tests and between-subject tests, as well as in tests (...) using instrumental variables that exploit exogenous variation in the state-level availability of opioids, a commonly abused substance.

This article examines the tensions in the identities of men who belong to the Promise Keepers movement by uncovering the social conditions that lead men to rethink gender and racial ideologies. Using participant observation and in-depth interviews, the author draws on gender and social movement scholarship to reveal how contradictory gender and racial ideologies shape PKs' identities. Furthermore, the PKs' impact on gender and race relations is also contradictory. PK fosters men's growth on an interactional level, allowing men to embrace (...) a more expressive and caring masculinity that includes cross-racial bonding. Simultaneously, however, PK ignores, and indirectly reinforces, the structural conditions that underpin gender and racial privilege among white men. (shrink)

Online platforms like Instagram cover potentially distressing imagery with a sensitive-content screen (blurred imagery plus a content warning). Previous research suggests people typically choose to “uncover” and view screened content. In three studies, we investigated whether the presence of screens mitigates the negative emotional impact of viewing content. In Study 1, participants viewed positive and neutral images, and screens (with an option to view the negative images beneath) for a 5-minute period. In Study 2, half the participants saw a grey (...) mask in place of the typical sensitive-content screen. In addition, each image appeared for a fixed period (5 s) and participants had no option to uncover it. Study 3 was like Study 2 except half the participants saw negative images preceded by a sensitive-content screen and half saw negative images without screens. Overall, participants reported a significant increase in state anxiety and negative affect from pre-to post task when they were exposed to sensitive-content screens, whether or not they were also exposed to the negative imagery beneath. Our data suggest sensitive-content screens cause negative responses – state anxiety and negative affect – that do not translate to an emotional benefit when people view negative content. (shrink)

In this paper, I address two widespread misconceptions about Descartes’s theory of love. Descartes defines love as a passion that ‘incites [the soul] to join in volition to the objects that appear to be suitable to it’. Several commentators assume joining in volition is an act of judgment, since forming judgments is the primary function of the will in the Meditations. However, I argue joining in volition is an act of imagining a whole one forms with an object of love. (...) I draw on Descartes’s account of volition in The Passions of the Soul to show forming images in one’s mind qualifies as a volition, on his view. Second, commentators often assume joining in volition is an essential part of love. However, I argue joining in volition is not an essential part of love because love is not identical to joining in volition, and love does not necessitate the soul to join in volition. (shrink)

This introduction to the edited volume on "Testimonial Injustice and Trust" provides (a) a brief overview of the philosophical debate on the notion of ‘testimonial injustice’ and (b) a summary of the 18 chapters constituting this volume. The contributions are divided into four thematic sections. These are (I) Rethinking Testimonial Injustice, (II) Testimonial Injustice and the Question of Trust, (III) The Public Spheres of Testimonial Injustice, and (IV) Testimonial Injustice and Public Health. The contributions criticize, complement, or expand on Fricker’s (...) central case of testimonial injustice and the proposed virtue of testimonial justice, thereby contributing to its better understanding and extending its scope. Moreover, through the application of theories of epistemic injustice, and testimonial injustice in particular, to new real-world cases and contexts, they seek to render our theories and concepts more robust and valuable.

Over the past several decades, urban community gardens have arisen in diverse and economically compromised neighborhoods across the U.S. as part of multiple environmental justice efforts. Urban community gardens have enabled users to mitigate the effects of many environmental injustices such as the impact of food deserts, nutrient poor food found at convenience stores, and pesticide laden grocery items. While these benefits have promulgated across the U.S., community gardens are also well known to be located in historically contaminated locations in (...) urban landscapes. These landscapes include former brownfield sites, superfund sites, and other abandoned spaces of contamination. Although environmental justice efforts to reclaim healthy food in urban community gardens are commendable, the presence and effects of potentially harmful contaminants is often overlooked as gardens are established. Further, governmental organizations tasked with protecting human health, such as the Environmental Protection Agency, have not established any health standards for urban community gardens. This creates many challenges in determining what is safe in community gardens, and garden mangers and users are often unaware of how severe the impacts of contamination may be or how to mitigate its effects. In this study, I highlight the prevalence of harmful concentrations of contaminants in urban community gardens in and near Seattle, Washington that are managed with organic practices. I then present the challenges and barriers to gardening in contaminated spaces. Finally, I make recommendations to address contamination in gardens spaces, and call for better regulatory standards and other forms of support to mitigate risk to users. (shrink)

This article examines the relation between the philosophy of language proposed by the later Wittgenstein in his Philosophical Investigations, and his ambition to cure philosophy from the mapping of linguistic expressions to extra-linguistic entities, on the one hand, and Chomsky's statements regarding language, meaning, and thought, and regarding the sense and non-sense of different fields of linguistic research, on the other. After a brief descriptive comparison of both approaches, it is argued that Chomsky's criticism on Wittgenstein's theory of meaning, or (...) on Wittgenstein's basic concepts such as e. g. rule-following, respectively, is unwarranted and caused by a fundamental misconception. Moreover, it is argued that the hypothesis evoked by Grewendorf, according to which „Chomsky would like to explain what Wittgenstein describes“, is misleading since the objects of investigation of Chomsky and Wittgenstein are in complementary distribution one to the other.
