The persistent educational challenges that fractions pose call for developing novel instructional methods to better prepare students for fraction learning. Here, we examined the effects of a 24-session, Cuisenaire rod intervention on a building block for symbolic fraction knowledge, continuous and discrete non-symbolic proportional reasoning, in children who have yet to receive fraction instruction. Participants were 34 second-graders who attended the intervention (intervention group) and 15 children who did not participate in any sessions (control group). As attendance at the intervention (...) sessions was irregular (median = 15.6 sessions, range = 1–24), we specifically examined the effect of the number of sessions completed on their non-symbolic proportional reasoning. Our results showed that children who attended a larger number of sessions increased their ability to compare non-symbolic continuous proportions. However, contrary to our expectations, they also decreased their ability to compare misleading discretized proportions. In contrast, children in the Control group did not show any change in their performance. These results provide further evidence on the malleability of non-symbolic continuous proportional reasoning and highlight the rigidity of counting knowledge interference on discrete proportional reasoning.

Hierarchical Bayesian models (HBMs) provide an account of Bayesian inference in a hierarchically structured hypothesis space. Scientific theories are plausibly regarded as organized into hierarchies in many cases, with higher levels sometimes called ‘paradigms’ and lower levels encoding more specific or concrete hypotheses. Therefore, HBMs provide a useful model for scientific theory change, showing how higher‐level theory change may be driven by the impact of evidence on lower levels. HBMs capture features described in the Kuhnian tradition, particularly the idea that (...) higher‐level theories guide learning at lower levels. In addition, they help resolve certain issues for Bayesians, such as scientific preference for simplicity and the problem of new theories. *Received July 2009; revised October 2009. †To contact the authors, please write to: Leah Henderson, Massachusetts Institute of Technology, 77 Massachusetts Avenue, 32D‐808, Cambridge, MA 02139; e‐mail: [email protected].

This essay analyzes the prominent role played by first wave feminism and by women writers between 1898-1903 as the Jamaica Times articulated a broad-based, middle class nationalism and launched a campaign to establish a Jamaican national literature. Largely overlooked, this archival material is significant because it suggests a subtle yet significant modification of anglophone Caribbean feminist, literary and nationalist historiography: first wave feminism was not introduced to Jamaica exclusively through black nationalist organizations in the late nineteenth and early twentieth century, (...) but rather, it emerged in a broader phenomenon of respectable, middle class nationalism, encompassing the overlapping projects of Jamaican nationalism and Pan Africanism. Thus, it becomes clear that first wave feminism, including white women writers, played a key but brief role in the formation of the middle class nationalism that would later dominate Jamaica's transition to independence. During the first five years of publication of the Jamaica Times, women wrote a significant proportion of the short stories published. However, they became marginalized as black folk culture became the defining symbol of national authenticity. The marginalization of middle class women writers reflects a broader pattern. In adopting first wave feminism from Britain and the United States, Jamaican nationalists reproduced colonial race and class dynamics that established an unbridgeable divide between middle class women, who served as ‘ladies bountiful,’ and the usually darker-skinned compatriots to whom they ministered. This class division continued to limit feminist activism in Jamaica throughout the first and second waves. (shrink)

The Covid‐19 pandemic highlighted the need to examine public trust in the U.S. Food and Drug Administration (FDA) vaccine approval process and the role of political influence in the FDA's decisions. Ensuring that the FDA is itself trustworthy is important for justifying public trust in its actions, like vaccine approvals, thereby promoting public health. We propose five conditions of trustworthiness that the FDA should meet when it reviews vaccines, even during emergencies: consistency with rules, proper expert or political decision‐makers, proper (...) decision‐making and noninterference, connection to public preference, and transparency of both reasons and procedures. The five conditions provide a road map of procedural and substantive requirements, which the FDA has variably implemented, focused on ensuring appropriate influence of political interests. While being a trustworthy agency cannot guarantee the public's trust, implementing these conditions builds a groundwork for public trust. (shrink)

Stoicism, a philosophy and set of practices developed in ancient times, commands ever-growing interest. Its present day, students, practitioners, teachers, and scholars adapt it to the challenges of modern life. This third volume brings together fifty pieces previously published in the Stoicism Today blog, ranging from personal essays to conference presentations, from bits of practical advice to history and interpretation, from polemics to symposia grappling with controversies, key issues, and central concepts. There is something for everyone in this volume. The (...) selections in this volume range over a vast array of topics. You will encounter authors applying Stoicism to parenting, medicine, psychotherapy, culinary arts, time-management, exercise and fitness, the emotions, relationships, the workplace, and the environment. Some selections examine useful practices, the nature and scope of the virtues, how to develop equanimity, resilience, and happiness. Comparative studies bring Stoicism into connection with Buddhism, mindfulness, self-help and productivity authors, and modalities of psychotherapy. This book bridges the gaps between philosophical reflection and practical wisdom, between study and interpretation of Stoicism, and its application to present-day issues and problems. The essays in this volume speak to anyone intending to start or to deepen a thoughtful Stoic life in the modern world. (shrink)

The purpose of this study was to assess the presence of ethics committees in rural critical access hospitals across the United States. Several studies have investigated the presence of ethics committees in rural health care facilities. The limitation of these studies is in the definition of ‘rural hospital’ and a regional or state focus. These limitations have created large variations in the study findings. In this nation-wide study we used the criteria of a critical access hospital (CAH), as defined by (...) the Medicare Rural Hospital Flexibility Program (Flex Program, 2007), to bring consistency and clarity to the assessment of the presence of ethics committees in rural hospitals. The Flex Monitoring Team conducted a national telephone survey of 381 CAH administrators throughout the United States. The survey covered a wide variety of questions concerning hospitals’ community benefit, impact activities, and whether the hospital had a formally established an ethics committee. About 230 (60%) of the respondents indicated they had a formally established ethics committee or ethics consultation program at their CAH. The prevalence of ethics committees declined as the CAH location became increasingly rural along a rural–urban continuum. Unlike CAHs, all rural Department of Veterans Affairs Medical Centers have ethics committees. The results of this study provide an understanding of the limited presence of ethics committee in rural America and the need to consider new approaches for providing ethics assistance. A virtual ethics committee network may be the most efficient and effective way of providing rural hospitals access to a knowledgeable ethics committee or consultant. (shrink)

Questionable research practices are a well-recognized problem in psychology. Coding bias, or the tendency of review studies to disproportionately cite positive findings from original research, has received comparatively little attention. Coding bias is more likely to occur when original research, such as neuroimaging, includes large numbers of effects, and is most concerning in applied contexts. We evaluated coding bias in reviews of structural magnetic resonance imaging studies of PCL-R psychopathy. We used PRISMA guidelines to locate all relevant original sMRI studies (...) and reviews. The proportion of null-findings cited in reviews was significantly lower than those reported in original research, indicating coding bias. Coding bias was not affected by publication date or review design. Reviews recommending forensic applications—such as treatment amenability or reduced criminal responsibility—were no more accurate than purely theoretical reviews. Coding bias may have contributed to a perception that structural brain abnormalities in psychopaths are more consistent than they actually are, and by extension that sMRI findings are suitable for forensic application. We discuss possible sources for the pervasive coding bias we observed, and we provide recommendations to counteract this bias in review studies. Until coding bias is addressed, we argue that this literature should not inform conclusions about psychopaths' neurobiology, especially in forensic contexts. (shrink)

Rumination is a maladaptive form of emotion regulation associated with psychopathology. Research with adults suggests that rumination covaries with diurnal cortisol rhythms, yet this has not been examined among adolescents. Here, we examine the day-to-day covariation between rumination and cortisol, and explore whether trait rumination is associated with alterations in diurnal cortisol rhythms among adolescent girls. Participants provided saliva samples 3 times per day over 3 days, along with daily reports of stress and rumination, questionnaires assessing trait rumination related to (...) peer stress, and diagnostic interviews assessing depression and anxiety. Greater rumination than usual during the day was associated with lower cortisol awakening responses the following morning, but this effect was not significant after accounting for wake time and an objective measure of adherence to the saliva sampling protocol. Trait rumination was associated with lower average cortisol levels at waking and flatter diurnal slopes, accounting for wake time, protocol compliance, and other factors. These patterns may help to explain why rumination is related to the development of psychopathology. (shrink)

Jeff Bub has developed an information-theoretic interpretation of quantum mechanics on the basis of the programme to reaxiomatise the theory in terms of information-theoretic principles. According to the most recent version of the interpretation, reaxiomatisation can dissolve some of the demands for explanation traditionally associated with the task of providing an interpretation for the theory. The key idea is that the real lesson we should take away from quantum mechanics is that the ‘structure of in- formation’ is not what we (...) thought it was. In particular a feature of the new structure is intrinsic randomness of measurement, which allegedly dissolves a significant part of the measurement problem. I argue that it is difficult to find an appropriate argument to support the claim that measurement is intrinsically random in the relevant sense. (shrink)

Philosophy of Science is a mid-level text for students with some grounding in philosophy. It introduces the questions that drive enquiry in the philosophy of science, and aims to educate readers in the main positions, problems and arguments in the field today. Alex Rosenberg is certainly well qualified to write such an introduction. His works cover a large area of the philosophy of natural and social sciences. In addition, the author of the argument that the ‘queen of the social (...) sciences’, economics, is not a science at all, can be counted on to show how the philosophy of science can be relevant to the understanding of the status of scientific knowledge and can provide a critical assessment of practitioners’ view of their field.

It is commonly thought that there is some tension between the second law of thermodynam- ics and the time reversal invariance of the microdynamics. Recently, however, Jos Uffink has argued that the origin of time reversal non-invariance in thermodynamics is not in the second law. Uffink argues that the relationship between the second law and time reversal invariance depends on the formulation of the second law. He claims that a recent version of the second law due to Lieb and Yngvason (...) allows irreversible processes, yet is time reversal invariant. In this paper, I attempt to spell out the traditional argument for incompatibility between the second law and time reversal invariant dynamics, making the assumptions on which it depends explicit. I argue that this argument does not vary with different versions of the second law and can be formulated for Lieb and Yngvason's version as for other versions. Uffink's argument regarding time reversal invariance in Lieb and Yngvason is based on a certain symmetry of some of their axioms. However, these axioms do not constitute the full expression of the second law in their system. (shrink)

In this article, I suggest that combining resources from philosophy and psychology can yield useful tools for philosophical counselling. More specifically, I argue for three theses: a) Iris Murdoch’s notion of just attention and Marshall Rosenberg’s method of non-violent communication are interestingly compatible; b) engaging in non-violent communication serves to support one’s endeavors to acquire the kind of clear vision Murdoch thinks doing well by others requires; and c) non-violent just communication would be beneficial to both counsellors and counselees (...) and thus a useful resource for philosophical counsellors.

In ‘A modal theory of function’, I gave an argument against all existing theories of function and outlined a new theory. Karen Neander and Alex Rosenberg argue against both my negative and my positive claim. My aim here is not merely to defend my account from their objections, but to (a) very briefly point out that the new account of etiological function they propose in response to my criticism cannot avoid the circularity worry either and, more importantly, to (b) (...) highlight, and attempt to make precise, an important feature of my modal theory that may have been understated in the original paper – that function attributions depend on the explanatory project at hand.

We introduce a dynamic model for evolutionary games played on a network where strategy changes are correlated according to degree of influence between players. Unlike the notion of stochastic stability, which assumes mutations are stochastically independent and identically distributed, our framework allows for the possibility that agents correlate their strategies with the strategies of those they trust, or those who have influence over them. We show that the dynamical properties of evolutionary games, where such influence neighborhoods appear, differ dramatically from (...) those where all mutations are stochastically independent, and establish some elementary convergence results relevant for the evolution of social institutions.

It is all too rare that a scholar trained in the history of art turns his critical attention to the issues of the nature of aesthetic value and the criteria of excellence in works of art. But these issues are Rosenberg's primary concern. His method is novel for he begins by discussing the importance of tradition for value judgment. Chapters are dedicated to five important critics from the sixteenth century to the present. In each chapter Rosenberg attempts to (...) extract the distinctive features of art that have been prominent in the criticism of each of these thinkers. The second part of the book, "Quality Judgment Today," applies the principles that Rosenberg has extracted to the evaluation of master drawings from the fifteenth to the twentieth century. While aestheticians may raise doubts about the subtlety of Rosenberg's philosophic distinctions, one is impressed by his attempt to do what philosophers sometimes only talk about, viz., to show how we can rationally evaluate and compare works of art. There are 168 plates and the book is beautifully executed in the style of the Bollingen series of the Mellon lectures.—R. J. B. (shrink)

Professional identity and competent ethical behaviors of nursing students are commonly developed through curricular inclusion of professional nursing values education. Despite the enactment of this approach, nursing students continue to express difficulty in managing ethical conflicts encountered in their practice. This descriptive correlational study explores the relationships between professional nursing values, self-esteem, and ethical decision making among senior baccalaureate nursing students. A convenience sample of 47 senior nursing students from the United States were surveyed for their level of internalized professional (...) nursing values (Revised Professional Nursing Values Scale), level of self-esteem (Rosenberg’s Self-Esteem Scale), and perceived level of confidence in ethical decision making. A significant positive relationship (p < 0.05) was found between nursing students’ professional nursing values and levels of self-esteem. The results of this study can be useful to nursing educators whose efforts are focused on promoting professional identity development and competent ethical behaviors of future nurses. (shrink)

The American Medical Association enacted its Code of Ethics in 1847, the first such national codification. In this volume, a distinguished group of experts from the fields of medicine, bioethics, and history of medicine reflect on the development of medical ethics in the United States, using historical analyses as a springboard for discussions of the problems of the present, including what the editors call "a sense of moral crisis precipitated by the shift from a system of fee-for-service medicine to a (...) system of fee-for-system medicine, better known as 'managed care.'" The authors begin with a look at how the medical profession began to consider ethical issues in the 1800s and subsequent developments in the 1900s. They then address the sociological, historical, ethical, and legal aspects of the practice of medicine. Later chapters discuss current and future challenges to medical ethics and professional values. Appendixes display various versions of the AMA's Code of Ethics as it has evolved over time. Contributors: George J. Annas, J.D., M.P.H., Arthur Isak Applbaum, Ph.D., Robert B.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Mapping Gendered Ecologies: Engaging with and Beyond Ecowomanism and Ecofeminism by K. Melchor Quick Hall and Gwyn KirkCecilia Herles (bio)K. Melchor Quick Hall and Gwyn Kirk, Mapping Gendered Ecologies: Engaging with and Beyond Ecowomanism and Ecofeminism. Lanham, MD: Rowman & Littlefield, 2021. ISBN- 978-1-7936-3946-2K. Melchor Quick Hall and Gwyn Kirk are leading feminist authors who have beautifully woven together an inspiring and diverse collection of essays in the (...) anthology, Mapping Gendered Ecologies: Engaging with and beyond Ecowomanism and Ecofeminism. What does it take to gather together some of the most eloquent voices of activists, teachers, farmers, artists, and organizers in an anthology focused on engaging with and beyond ecowomanism and ecofeminism, and what could this cultivate? I find Hall and Kirk's reflections on the process and their approach to collaboration illustrate some of the tools needed to address complex issues of disasters, the global pandemic, climate justice, white supremacy, gender oppression, and practices of domination. Their approach is to build relationships, acknowledge vulnerability, and appreciate differences in experiences. It seems fitting that this project initially began with Margo Okazawa-Rey who connected Hall and Kirk together. Okazawa-Rey's introduction generated the openness needed to bring this collection to fruition. Mapping as the thematic image of this collection is found in destructive boundary-making, the violence of enslavement, wars, and the dumping of contaminants in the environment. Mapping is also evident in the physical, temporal, and evolving locations in which Okazawa-Rey's work of sustaining community and recognizing interconnections across locations opens up the time and spaces to envision peace.This collection marks a shift away from the elitism of academic spaces by illuminating connections between community and university, and actively resisting against patriarchal notions of what counts as expertise and scholarship. The anthology draws attention to personal experiences as fundamentally relevant to perspectives about place, location, and [End Page 97] belonging and relations with land, water, sky and nonhumans. It begins with an autobiographical account by Hall who brilliantly weaves together her life story with her analytical insight in illustrating how Black geographies show spaces as often hard to map and in flux for the marginalized. In "Darkness All around Me: Black Waters, Land, Animals, and Sky" Hall notes how she is unable to discuss her understanding and relationship with Nature outside of being a Black Woman. When she poses the question, "how would our maps be different if they were rooted in the histories and realities of people of color?" (23) Hall pivots mapping to the contingent, unstable complexities that mark Black people's relations with land and food. In doing so, Hall reveals compelling insights into trauma, anxieties, and relationships with land and water in shifting landscapes. Connecting to the mission of Soul Fire Farm, to resist the US food apartheid and mobilize towards food justice, Hall reveals the possibilities for reparative healing properties in agricultural activities at Soul Fire Farm. Hall's narrative about racialized hierarchies recognizes how human hierarchies are connected to human-nonhuman animal divisions, raising the question of "How might we imagine freeing ourselves and other animals from the systems that seek to devalue us as (human and nonhuman) beings?" (27). Hall intervenes and challenges geographical mapping centered in white frameworks rooted in claims of stolen territories and measured in segregation and displacement. Pointing to Black shoals, Black food geographies, and Afrofuturism, to name a few, Hall is marking potential paths to shared liberation. Although Hall does not identify strongly as ecofeminist nor ecowomanist, this provides a promising direction for ecowomanist and ecofeminist inquiries, speaking to the need to explore what it takes for shared liberation. This direction also has the potential to offer insight into an alternative mapping for disability justice. Hall's acknowledgement of "being out of place" connects to the disability justice work of Sunaura Taylor (2014) and Leah Lakshmi Piepzna-Samarasinha (2018) in the mapping of access in describing surroundings and focusing on interconnectedness.In Kirk's autobiographical account, "Roots, Branches, Wings" she points to how Margo Okazawa-Rey (2020) introduced her to philosopher Alan Rosenberg's (1998) distinction between knowing and understanding. In contrast to knowing facts that... (shrink)

Fresnel's theory of light was (a) impressively predictively successful yet (b) was based on an "entity" (the elastic-solid ether) that we now "know" does not exist. Does this case "confute" scientific realism as Laudan suggested? Previous attempts (by Hardin and Rosenberg and by Kitcher) to defuse the episode's anti-realist impact. The strongest form of realism compatible with this case of theory-rejection is in fact structural realism. This view was developed by Poincare who also provided reasons to think that it (...) is the only realist view of theories that really makes sense. (shrink)
