How do teachers’ gestures influence students’ learning? This article reviews research investigating the role of gestures in communication, focusing on teachers’ communication with their students, primarily in mathematics and science instruction. We first briefly consider gesture's role in communication more generally as a backdrop for considering teaching as a special context for communication. We then describe teachers’ spontaneous gesturing in teaching contexts, and we consider how teachers’ spontaneous gestures might influence students’ learning. We then consider experimental studies that provide causal (...) support for the effects of teachers’ gestures on students’ learning. We conclude by discussing future directions and implications for educational practice. (shrink)

IntroductionAnorexia nervosa promotes psychological distress in caregivers who adopt different coping strategies. Dysfunctional caregiving styles exacerbate further distress in the patient promoting the maintenance of the illness. We aimed to assess the possible contribution of personality traits of caregivers to the adoption of different coping strategies to deal with the affected relative.MethodsAbout 87 adolescents with AN were recruited. Their parents completed the Family Coping Questionnaire for Eating Disorders and the Temperament and Character Inventory-Revised. Differences between mothers and fathers were assessed (...) through the independent sample t-test. Multivariate regression analyses were run to assess if personality traits, the occurrence of psychiatry conditions in the parents, the marital status, and the duration of the illness predicted parental coping strategies.ResultsThe group of mothers showed higher levels of avoidance and seeking for information coping strategies than the sample of fathers. Lower illness duration predicted higher collusion with the illness in both parents. Harm avoidance, cooperativeness, and self-directedness positively predicted parental coercion, collusion, and seeking for information strategies with some differences between mothers and fathers.DiscussionIllness duration and personality traits of parents affect the type of parental coping strategies developed to face AN in adolescents. These variables should be considered in the assessment of families of adolescents with AN and may be addressed to promote more fine-tuned clinical interventions for caregivers. (shrink)

The phone-hacking scandal that led to the closure of the News of the World newspaper in Britain has prompted international debate about media practices and regulation. It is timely to broaden the discussion about journalistic ethics and conduct to include consideration of the impact of media practices upon the population's health. Many commercial organisations cultivate relationships with journalists and news organisations with the aim of influencing the content of health-related news and information communicated through the media. Given the significant influence (...) of the media on the health of individuals and populations, we should be alert to the potential impact of industry–journalist relationships on health care, health policy and public health. The approach taken by the medical profession to its interactions with the pharmaceutical industry provides a useful model for management of industry influence. (shrink)

Solutions to word problems are moderated by the semantic alignment of real-world relations with mathematical operations. Categorical relations between entities are aligned with addition, whereas certain functional relations between entities are aligned with division. Similarly, discreteness vs. continuity of quantities is aligned with different formats for rational numbers. These alignments have been found both in textbooks and in the performance of college students in the USA and in South Korea. The current study examined evidence for alignments in Russia. Textbook analyses (...) revealed semantic alignments for arithmetic word problems, but not for rational numbers. Nonetheless, Russian college students showed semantic alignments both for arithmetic operations and for rational numbers. Since Russian students exhibit semantic alignments for rational numbers in the absence of exposure to examples in school, such alignments likely reflect intuitive understanding of mathematical representations of real-world situations.

BackgroundYouth are increasingly aware of the negative effects of climate change on the planet and human health, but this knowledge can often come with significant affective responses, such as psychological distress, anger, or despair. Experiencing major “negative” emotions, like worry, guilt, and hopelessness in anticipation of climate change has been identified with the term eco-anxiety. Emerging literature focuses on adults' experience; however, little is known about the ways in which children and youth experience eco-anxiety.ObjectivesThe aim of this review was to: (...) identify the available evidence on the topic of eco-anxiety in children, clarify the mental health consequences brought by the awareness of climate change in this population, and identify knowledge gaps in the literature and considerations for future research.MethodsGiven that the research on the topic of eco-anxiety in children is limited, that there are very few randomized controlled trials, and that the goal is not to analyze individual studies in-depth, a scoping review was used. Keywords pertaining to the themes of eco-anxiety, climate change and children were used as search terms in five databases. Journal articles using qualitative and quantitative methods, as well as gray literature were examined by two independent reviewers. A descriptive-analytical method was used to chart the data that emerged from the literature. Eighteen articles were considered in the final analysis.ResultsEvidence confirms that children experience affective responses and eco-anxiety in reaction to then awareness of climate change. Mental health outcomes include depression, anxiety, and extreme emotions like sadness, anger, and fear. Youth from vulnerable communities, like indigenous communities, or those who have strong ties to the land are often identified as being emotionally impacted by climate change. The literature analyzed also describes how children and youth are coping with eco-anxiety, including maladaptive and adaptive responses. Preliminary considerations for parents, teachers and educators, mental health care providers, school systems, adults and people of power include adding age-appropriate climate education to the school curriculum, considering youth's emotions, and promoting healthy coping through empowerment. Important gaps exist in the definition of eco-anxiety in youth, as various characterizations of this emerging concept are found across articles. (shrink)

Introduction: Although deep brain stimulation often improves levodopa-responsive gait symptoms, robust therapies for gait dysfunction from Parkinson's disease remain a major unmet need. Walking speed could represent a simple, integrated tool to assess DBS efficacy but is often not examined systematically or quantitatively during DBS programming. Here we investigate the reliability and functional significance of changes in gait by directional DBS in the subthalamic nucleus.Methods: Nineteen patients underwent unilateral subthalamic nucleus DBS surgery with an eight-contact directional lead in the most (...) severely affected hemisphere. They arrived off dopaminergic medications >12 h preoperatively and for device activation 1 month after surgery. We measured a comfortable walking speed using an instrumented walkway with DBS off and at each of 10 stimulation configurations at the midpoint of the therapeutic window. Repeated measures of ANOVA contrasted preoperative vs. maximum and minimum walking speeds across DBS configurations during device activation. Intraclass correlation coefficients examined walking speed reliability across the four trials within each DBS configuration. We also investigated whether changes in walking speed related to modification of step length vs. cadence with a one-sample t-test.Results: Mean comfortable walking speed improved significantly with DBS on vs. both DBS off and minimum speeds with DBS on. Pairwise comparisons showed no significant difference between DBS off and minimum comfortable walking speed with DBS on. Intraclass correlations were ≥0.949 within each condition. Changes in comfortable walk speed were conferred primarily by changes in step length.Conclusion: Acute assessment of walking speed is a reliable, clinically meaningful measure of gait function during DBS activation. Directional and circular unilateral subthalamic DBS in appropriate configurations elicit acute and clinically significant improvements in gait dysfunction related to PD. Next-generation directional DBS technologies have significant potential to enhance gait by individually tailoring stimulation parameters to optimize efficacy. (shrink)

Competition among scientists for funding, positions and prestige, among other things, is often seen as a salutary driving force in U.S. science. Its effects on scientists, their work and their relationships are seldom considered. Focus-group discussions with 51 mid- and early-career scientists, on which this study is based, reveal a dark side of competition in science. According to these scientists, competition contributes to strategic game-playing in science, a decline in free and open sharing of information and methods, sabotage of others’ (...) ability to use one’s work, interference with peer-review processes, deformation of relationships, and careless or questionable research conduct. When competition is pervasive, such effects may jeopardize the progress, efficiency and integrity of science. (shrink)

Critical-philosophical commentary on theses defended in scientific articles may be guided by two distinct perspectives, each leading to inquiries and styles of responses that are both distinct and complementary: an internal perspective and an external perspective. The internal commentator belongs to the same epistemological field of the authors and, as such, shares the same categorical assumptions and the same Weltanschauung explored in the text. The dialogue with this commentator emphasizes the minutiae of the observation of the shared scientific reality and (...) points out the frontiers toward which the discussion of a scientific branch must advance. The external commentator, in contrast, emphasizes the categorical... (shrink)

Programs, policies, and technologies — particularly those concerned with health equity — are often designed with justice envisioned as the end goal. These policies or interventions, however, frequently fail to recognize how the beneficiaries have historically embodied the cumulative effects of marginalization, which undermines the effectiveness of the intended justice. These well-meaning attempts at justice are bounded by greater socio-historical constraints. Bounded justice suggests that it is impossible to attend to fairness, entitlement, and equity when the basic social and physical (...) infrastructures underlying them have been eroded by racism and other historically entrenched isms. Using the case of Brazil’s National Health Policy for the Black Population, this paper proposes that bounded justice can contribute to justice discourses by serving as a concept, a proffering to a multi-disciplinary conceptual framework, and a potential analytic for those interested in the design of policy, technology, and programmatic interventions towards health equity.

This paper demonstrates that accounting for the moral harm of selecting for deafness is not as simple or obvious as the widespread negative response from the hearing community would suggest. The central questions addressed by the paper are whether our moral disquiet with regard to selecting for deafness can be adequately defended, and if so, what this might entail. The paper considers several different strategies for accounting for the supposed moral harm of selecting for deafness and concludes that the deaf (...) case cannot be treated in isolation. Accounting for the moral harm of selecting for deafness necessarily entails moral implications for other cases of procreation and procreative decision-making, including unassisted coital reproduction. The lesson to be learned from the deaf case is that we need norms that govern not just the use of reproductive technology, but procreation and procreative decision-making in all of its various forms.

Researchers are studying how artificial intelligence (AI) can be used to better detect, prognosticate and subgroup diseases. The idea that AI might advance medicine’s understanding of biological categories of psychiatric disorders, as well as provide better treatments, is appealing given the historical challenges with prediction, diagnosis and treatment in psychiatry. Given the power of AI to analyse vast amounts of information, some clinicians may feel obligated to align their clinical judgements with the outputs of the AI system. However, a potential (...) epistemic privileging of AI in clinical judgements may lead to unintended consequences that could negatively affect patient treatment, well-being and rights. The implications are also relevant to precision medicine, digital twin technologies and predictive analytics generally. We propose that a commitment to epistemic humility can help promote judicious clinical decision-making at the interface of big data and AI in psychiatry. (shrink)

Ethics researchers advise managers of organizations to link rewards and punishments to ethical and unethical behavior, respectively. We build on prior research maintaining that organizations operate at Kohlbergs stages of moral reasoning, and explain how the over-reliance on rewards and punishments encourages employees to operate at Kohlbergs lowest stages of moral reasoning. We advocate designing organizations as ethical communities and relying on different assumptions about employees in order to foster ethical reasoning at higher levels. Characteristics associated with ethical communities are (...) identified and AES Corporation and Semco S/A serve as examples of corporations exhibiting the design characteristics and assumptions of ethical organizations.

A central goal of the scientific endeavor is to explain phenomena. Scientists often attempt to explain a phenomenon by way of representing it in some manner—such as with mathematical equations, models, or theory—which allows for an explanation of the phenomenon under investigation. However, in developing scientific representations, scientists typically deploy simplifications and idealizations. As a result, scientific representations provide only partial, and often distorted, accounts of the phenomenon in question. Philosophers of science have analyzed the nature and function of how (...) scientists construct representations, deploy idealizations, and provide explanations. As such, our aim in this special issue is to bring these three pillars of research into closer contact with the contributions to it focusing on three main themes. -/- The first set of papers, Alan Baker (2021) and Marc Lange (2021), address mathematical explanations in science. Baker (2021), a proponent of mathematical Platonism, examines its capacity to evade the critique that the so-called Enhanced Indispensability Argument is circular. Lange (2021) examines distinctively mathematical explanations, arguing that neither Platonism nor representationalism are successful paths, and instead argues in favor of Aristotelian realism. A second theme emerging from the papers in this special issue is the impact that various conceptualizations of idealization have on our abilities to offer scientific explanations, to pro- duce an analysis of what explanations are or should be, and to understand scientific representation. Peter Tan (2021) suggests amending inferentialist accounts of scientific representation to account for inconsistent idealizations. Michael Strevens (2021) advocates a view wherein the introduction of idealizations into a model is legitimate so long as it pertains to non-difference-making factors, arguing for a logical reading of the notion of difference-making. Natalia Carrillo and Tarja Knuuttila (2022) offer an alternative account to the idealization-as-distortion view, emphasizing instead the holistic nature of idealization. -/- Finally, contributions by Carrillo and Knuuttila (2022), Terzian (2021), Valente (2021), and Rodriguez (2021) illustrate how issues regarding idealization, representation, and explanation are applied to specific contexts and across various sciences. Carrillo and Knuuttila (2022) examine conceptions of idealization in the context of models of the nerve impulse. Giulia Terzian (2021) extends the discussion of idealizations to the context of generative linguistics. Giovanni Valente (2021) examines how idealizations and evaluations of accurate representation impact capacities to explain phenomena in the context of statistical thermodynamics. Quentin Rodriguez (2021) examines the role of idealizations and analogies in various strategies to explain critical phenomena. -/- In what follows, we offer a brief overview of important philosophical issues connected to representation, idealization, and explanation in science. We then provide short summaries of the eight papers in this special issue. (shrink)

Michael Nair-Collins and Franklin Miller are right to emphasise that, in order to deliberate responsibly about ethical and legal questions related to brain death and organ donation, it is crucial to answer the question of whether or not ‘brain death’i does indeed mark the biological death of the organism. Nonetheless, I disagree with the authors’ conclusion that brain death does not indicate the death of the human organism. Death can never be defined in merely biological terms, because any biological conception (...) of death relies on metaphysical presuppositions regarding what it means to be an ‘organism as a whole’, rather than an aggregate of cells and tissues. Death is a change in substance —that is, a change from one type of entity to another — not the cessation of all biological life. Organismal death occurs well before all of the organism’s parts irreversibly cease vital activity and decompose into inorganic matter. Biological life in some form can and usually does continue after organismal death at least for a time, with recent evidence indicating that animal cell networks continue to perform complex functions like stress response, immune response and inflammation response up to several days postmortem.1 With external support, many cells and tissues can continue to perform their functions ex vivo for long periods of time or even indefinitely.2 Henrietta Lax died in 1951, but cells derived from her cancerous cervical cells ….

Finally, on the basis of a deeper metaphysical analysis, I offer a revised (...) rationale for the validity of the neurological criterion of human death. (shrink)

SummaryThis article documents understandings and responses to mass drug administration for the treatment and prevention of lymphatic filariasis among adults and children in northern coastal Tanzania from 2004 to 2011. Assessment of village-level distribution registers, combined with self-reported drug uptake surveys of adults, participant observation and interviews, revealed that at study sites in Pangani and Muheza districts the uptake of drugs was persistently low. The majority of people living at these highly endemic locations either did not receive or actively rejected (...) free treatment. A combination of social, economic and political reasons explain the low uptake of drugs. These include a fear of treatment ; divergence between biomedical and local understandings of lymphatic filariasis; and limited and ineffective communication about the rationale for mass treatment. Other contributory factors are the reliance upon volunteers for distribution within villages and, in some locations, strained relationships between different groups of people within villages as well as between local leaders and government officials. The article also highlights a disjuncture between self-reported uptake of drugs by adults at a village level and the higher uptake of drugs recorded in official reports. The latter informs claims that elimination will be a possibility by 2020. This gives voice to a broader problem: there is considerable pressure for those implementing MDA to report positive results. The very real challenges of making MDA work are pushed to one side – adding to a rhetoric of success at the expense of engaging with local realities. It is vital to address the kind of issues raised in this article if current attempts to eliminate lymphatic filariasis in mainland coastal Tanzania are to achieve their goal. (shrink)

Under the banner of “data for good,” companies in the technology, finance, and retail sectors supply their proprietary datasets to development agencies, NGOs, and intergovernmental organizations to help solve an array of social problems. We focus on the activities and implications of the Data for Climate Action campaign, a set of public–private collaborations that wield user data to design innovative responses to the global climate crisis. Drawing on in-depth interviews, first-hand observations at “data for good” events, intergovernmental and international organizational (...) reports, and media publicity, we evaluate the logic driving Data for Climate Action initiatives, examining the implications of applying commercial datasets and expertise to environmental problems. Despite the increasing adoption of Data for Climate Action paradigms in government and public sector efforts to address climate change, we argue Data for Climate Action is better seen as a strategy to legitimate extractive, profit-oriented data practices by companies than a means to achieve global goals for environmental sustainability.

Why might it be beneficial for adults to process fractions componentially? Recent research has shown that college-educated adults can capitalize on the bipartite structure of the fraction notation, performing more successfully with fractions than with decimals in relational tasks, notably analogical reasoning. This study examined patterns of relational priming for problems with fractions in a task that required arithmetic computations. College students were asked to judge whether or not multiplication equations involving fractions were correct. Some equations served as structurally inverse (...) primes for the equation that immediately followed it. Students with relatively high math ability showed relational priming both with and without high perceptual similarity. Students with relatively low math ability also showed priming, but only when the structurally inverse equation pairs were supported by high perceptual similarity between numbers. Several additional experiments established boundary conditions on relational priming with fractions. These findings are interpreted in terms of componential processing of fractions in a relational multiplication context that takes advantage of their inherent connections to a multiplicative schema for whole numbers.

Since ancient Athens, democrats have taken pride in their power and inclination to change their laws, yet they have also sought to counter this capacity by creating immutable laws. In Democracy and Legal Change, Melissa Schwartzberg argues that modifying law is a fundamental and attractive democratic activity. Against those who would defend the use of 'entrenchment clauses' to protect key constitutional provisions from revision, Schwartzberg seeks to demonstrate historically the strategic and even unjust purposes unamendable laws have typically served, (...) and to highlight the regrettable consequences that entrenchment may have for democracies today. Drawing on historical evidence, classical political theory, and contemporary constitutional and democratic theory, Democracy and Legal Change reexamines the relationship between democracy and the rule of law from a new, and often surprising, set of vantage points.

This essay brings psychoanalytic theory on trauma together with film and television criticism on rape narrative in an analysis of Michael Coel’s 2020 series I May Destroy You. Beyond the limited carceral framework of the police procedural, which dislocates the act of violence from the survivor’s history and context, Coel’s polyvalent, looping narrative metabolizes rape television’s forms and genres in order to stage and restage both trauma and genre again and anew. Contesting common conceptions of vulnerability and susceptibility that prefigure (...) a violent breach of autonomy, Coel’s series and her interviews about it invite an ethics of looking that embraces a curiosity in the unknowable and untreatable kernel of subjective experience and defies and resists a policing of the survivor’s thoughts and emotions. By emphasizing and exploring what psychoanalysis calls the “afterwardness” of trauma, Coel foregrounds her main character’s subjectivity prior to her victimization, widens the sphere of consequence beyond the victim and criminal justice system to the survivor’s larger community, and entreats that community to preserve a space for her to look and look again at everything, without judgment.

Margaret Morrison, (2015) Reconstructing Reality: Models, Mathematics, and Simulations. Oxford University Press, New York. -/- Scientific models, mathematical equations, and computer simulations are indispensable to scientific practice. Through the use of models, scientists are able to effectively learn about how the world works, and to discover new information. However, there is a challenge in understanding how scientists can generate knowledge from their use, stemming from the fact that models and computer simulations are necessarily incomplete representations, and partial descriptions, of their (...) target systems. In order to construct a model, one must make idealizations, approximations, and abstractions. Given these constraints in constructing models, there is a question of whether they can provide new insight into how real systems actually work. So, how is it that highly abstract models inform us about the nature of the world, and more specifically, how do they provide explanatory knowledge? In Reconstructing Reality: Models, Mathematics, and Simulations, philosopher Margaret Morrison undertakes this task of ... (shrink)

This essay investigates Josiah Royce's sustained interest in the Platonic dialogues by focusing not only on Royce's explicit commentary on Socrates and Plato but also on significant philosophical connections between Royce and these figures. In section 1, we explain the nature of loyalty according to Royce and how Socratic loyalty exemplifies Royce's ideas in both evident and surprising ways. In section 2, we claim that Royce's treatment of “lost causes” (particularly truth as a lost cause) relates to Socrates' dedication to (...) the logos; the Platonic dialogues are reinvestigated in order to make this point. In section 3, we explain the nature of “cause” both in Royce's thought and in the Platonic dialogues in order to see how loyalty to a cause culminates in the art of wise living—Socrates' philosophical practice.
