  1. Repackaging the Past: Commodification, Consumerism and the Study of History

    ERIC Educational Resources Information Center

    Armstrong, Paul; Coles, Janet

    2008-01-01

    In this paper, we argue against the over-simplistic accusation that the media "dumb down" the study of history. Instead, we critically examine the contemporary presentation of history on British television within a framework of analysis of commodification and consumption. We argue that central to the debate is the idea that whilst…

  8. AIDS, religious enthusiasm and spiritual insecurity in Africa.

    PubMed

    Ashforth, Adam

    2011-01-01

    The connection between the AIDS epidemic and the efflorescence of religious 'enthusiasm' (construed in both classical and contemporary senses) in Africa in recent decades is best understood, this paper argues, by reference to a concept of 'spiritual insecurity'. The article offers a general description of the condition of spiritual insecurity and argues that it is best studied within a relational realist paradigm. The article presents a critique of the concept of 'belief' as commonly used in the social science of religion, arguing instead for an opening of the study of social relations to include the universe of relations within which people experience the world, including their relations with entities such as spiritual beings that might otherwise be considered virtual.

  9. Student Conceptions of Oral Presentations

    2007-01-01

    A phonographic study of students' experience of oral presentations in an open learning theology programme constituted three contrasting conceptions of oral presentations--as transmission of ideas; as a test of students' understanding of what they were studying; and as a position to be argued. Each of these conceptions represented a combination of…

  10. What is Intrinsic Motivation? A Typology of Computational Approaches

    PubMed Central

    Oudeyer, Pierre-Yves; Kaplan, Frederic

    2007-01-01

    Intrinsic motivation, centrally involved in spontaneous exploration and curiosity, is a crucial concept in developmental psychology. It has been argued to be a crucial mechanism for open-ended cognitive development in humans, and as such has gathered a growing interest from developmental roboticists in the recent years. The goal of this paper is threefold. First, it provides a synthesis of the different approaches of intrinsic motivation in psychology. Second, by interpreting these approaches in a computational reinforcement learning framework, we argue that they are not operational and even sometimes inconsistent. Third, we set the ground for a systematic operational study of intrinsic motivation by presenting a formal typology of possible computational approaches. This typology is partly based on existing computational models, but also presents new ways of conceptualizing intrinsic motivation. We argue that this kind of computational typology might be useful for opening new avenues for research both in psychology and developmental robotics. PMID:18958277

  11. Can the behavioral sciences self-correct? A social epistemic study.

    PubMed

    Romero, Felipe

    2016-12-01

    Advocates of the self-corrective thesis argue that scientific method will refute false theories and find closer approximations to the truth in the long run. I discuss a contemporary interpretation of this thesis in terms of frequentist statistics in the context of the behavioral sciences. First, I identify experimental replications and systematic aggregation of evidence (meta-analysis) as the self-corrective mechanism. Then, I present a computer simulation study of scientific communities that implement this mechanism to argue that frequentist statistics may converge upon a correct estimate or not depending on the social structure of the community that uses it. Based on this study, I argue that methodological explanations of the "replicability crisis" in psychology are limited and propose an alternative explanation in terms of biases. Finally, I conclude suggesting that scientific self-correction should be understood as an interaction effect between inference methods and social structures. Copyright © 2016 Elsevier Ltd.

    ERIC Educational Resources Information Center

    Jaffe, Samuel

    This paper discusses some past and present interdisciplinary approaches to foreign language and literature (FLL) studies. It is argued that the current unpopularity of FLL studies in the United States is the consequence of falling away from viable traditions of scholarship and teaching in this area. A model for reform which reawaken interest in…

  13. The Concept of “Metaemotion”: What is There to Learn From Research on Metacognition?

    PubMed Central

    Norman, Elisabeth; Furnes, Bjarte

    2014-01-01

    We first present a selection of vignette examples from empirical psychological research to illustrate how the phenomenon of metaemotion (Gottman, Katz, & Hooven, 1996; Mendonça, 2013) is studied within different domains of psychology. We then present a theoretical distinction which has been made between three facets of metacognition, namely metacognitive experiences, metacognitive knowledge, and metacognitive strategies (e.g., Efklides, 2008; Flavell, 1979). Referring back to the vignette examples from metaemotion research, we argue that a similar distinction can be drawn between three facets of metaemotion, namely metaemotional experiences, metaemotional knowledge, and metaemotional strategies. We argue that this distinction clarifies some of the unresolved issues in metaemotion research, and therefore has important implications for the study of metaemotion, both methodologically and theoretically.

    Research has shown that novice writers tend to ignore opposing viewpoints when framing and developing arguments in writing, a phenomenon commonly referred to as my-side bias. In the present article, we contrast two forms of argumentative discourse conditions (arguing to persuade and arguing to reach consensus) and examine their differential…

  15. REESTABLISHING "THE SOCIAL" IN RESEARCH ON DEMOCRATIC PROCESSES: MID-CENTURY VOTER STUDIES AND PAUL F. LAZARSFELD'S ALTERNATIVE VISION.

    PubMed

    Christensen, Michael

    2015-01-01

    Voter studies conducted in the United States during the first decades after World War II transformed social scientific research on democracy. Especially important were the rapid innovations in survey research methods developed by two prominent research centers at Columbia University and the University of Michigan. This article argues that the Columbia and Michigan voter studies presented two visions for research on democracy. Where the Michigan research produced quantitative measures expressing the 'political behavior' of the electorate, the Columbia studies, and especially Paul F. Lazarsfeld, presented an alternative vision for qualitative research on political choice. Largely ignored by later voter studies, this vision prefigured much contemporary research on democracy that embraces a qualitative or interpretive approach. This article reconstructs Lazarsfeld's alternative vision, describes the institutional context in which scholars disregarded it in favor of formal quantitative models, and argues for its recognition as a forerunner to qualitative research on democratic processes. © 2015 Wiley Periodicals, Inc.

  18. Life's end: Ethnographic perspectives.

    PubMed

    Goodwin-Hawkins, Bryonny; Dawson, Andrew

    2018-01-01

    In this introduction to the special issue, Life's End: Ethnographic Perspectives, we review the field of anthropological studies of death and dying. We make the argument that, largely because of its sub-disciplining into the larger field of the anthropology of religion, ritual and symbolism, the focus of anthropological research on death has been predominantly on post- rather than pre-death events, on death's beginnings rather than life's ends. Additionally, we argue that an anthropological aversion to the study of dying may also lie in the intimacy of the discipline's principal method, ethnography. Contrastingly, we argue that this very methodological intimacy can be a source of insight, and we offer this as a rationale for the special issue as a whole, which comprises eight ethnographic studies of dying and social relations at life's end from across Africa, Australia, Europe, and North America. Each of these studies is then summarized, and a rationale for their presentation around the themes of "structures of dying," "care for the dying," "hope in dying," and "ending life" is presented.

  19. Inclusion of Gaming Disorder in ICD has more advantages than disadvantages

    PubMed Central

    Király, Orsolya; Demetrovics, Zsolt

    2017-01-01

    This paper is a response to a recent debate paper in which Aarseth et al. argue that the inclusion of a formal diagnosis and categories for problematic video gaming or Gaming Disorder (GD) in the World Health Organization’s 11th Revision of the International Classification of Diseases (ICD-11) is premature and therefore the proposal should be removed. The present authors systematically address all the six main arguments presented by Aarseth et al. and argue that, even though some of the concerns presented in the debate paper are legitimate, the inclusion of GD in ICD-11 has more advantages than disadvantages. Furthermore, the present authors also argue that the two GD subtypes (“GD, predominantly online” and “GD, predominantly offline”) are unnecessary and rather problematic; the main category for GD would be perfectly sufficient.

  3. Structural equation modeling and natural systems

    USGS Publications Warehouse

    Grace, James B.

    2006-01-01

    This book, first published in 2006, presents an introduction to the methodology of structural equation modeling, illustrates its use, and goes on to argue that it has revolutionary implications for the study of natural systems. A major theme of this book is that we have, up to this point, attempted to study systems primarily using methods (such as the univariate model) that were designed only for considering individual processes. Understanding systems requires the capacity to examine simultaneous influences and responses. Structural equation modeling (SEM) has such capabilities. It also possesses many other traits that add strength to its utility as a means of making scientific progress. In light of the capabilities of SEM, it can be argued that much of ecological theory is currently locked in an immature state that impairs its relevance. It is further argued that the principles of SEM are capable of leading to the development and evaluation of multivariate theories of the sort vitally needed for the conservation of natural systems.

    A common move in the study of creativity and performativity is to present the former as an antidote to the latter. Might we, therefore, see work on creativity in education as heralding an era of post-performativity? In this paper I argue that the portrayal of performativity in the literature on creativity presents an overly simplistic (vulgar?)…

  11. Linguistic explanation and domain specialization: a case study in bound variable anaphora.

    PubMed

    Adger, David; Svenonius, Peter

    2015-01-01

    The core question behind this Frontiers research topic is whether explaining linguistic phenomena requires appeal to properties of human cognition that are specialized to language. We argue here that investigating this issue requires taking linguistic research results seriously, and evaluating these for domain-specificity. We present a particular empirical phenomenon, bound variable interpretations of pronouns dependent on a quantifier phrase, and argue for a particular theory of this empirical domain that is couched at a level of theoretical depth which allows its principles to be evaluated for domain-specialization. We argue that the relevant principles are specialized when they apply in the domain of language, even if analogs of them are plausibly at work elsewhere in cognition or the natural world more generally. So certain principles may be specialized to language, though not, ultimately, unique to it. Such specialization is underpinned by ultimately biological factors, hence part of UG.

  13. Recognizing Moral Identity as a Cultural Construct.

    PubMed

    Jia, Fanli; Krettenauer, Tobias

    2017-01-01

    Current research on moral identity shows that moral identity predicts moral action in Western cultures but not in non-Western cultures. The present paper argues that this may be due to the fact that the concept of moral identity is culturally biased. In order to remedy this situation, we argue that researchers should broaden their scopes of inquiry by adding a cultural lens to their studies of moral identity. This change is important because although some concept of moral identity likely exists in all cultures, it may function in different ways and at different levels in each place. We propose that moral identity is a context-dependent construct tied to varying social and cultural obligations. We argue that Western moral identity stresses an individually oriented morality, whereas, people from Eastern cultures consider a highly moral person to be societally oriented. We conclude by discussing the implications of this view for future research.

    Bonini et al. [2] present psychological data that they take to support an 'epistemic' account of how vague predicates are used in natural language. We argue that their data more strongly supports a 'gap' theory of vagueness, and that their arguments against gap theories are flawed. Additionally, we present more experimental evidence that supports gap theories, and argue for a semantic/pragmatic alternative that unifies super- and subvaluationary approaches to vagueness.

  7. Teaching ethical aptitude to graduate student researchers.

    PubMed

    Weyrich, Laura S; Harvill, Eric T

    2013-01-01

    Limited time dedicated to each training areas, irrelevant case-studies, and ethics "checklists" have resulted in bare-bones Responsible Conduct of Research (RCR) training for present biomedical graduate student researchers. Here, we argue that science graduate students be taught classical ethical theory, such as virtue ethics, consequentialist theory, and deontological theory, to provide a basic framework to guide researchers through ethically complex situations and examine the applicability, implications, and societal ramifications of their research. Using a relevant biomedical research example to illustrate this point, we argue that proper ethics training for graduate student researchers not only will enhance current RCR training, but train more creative, responsible scientists.

  8. Distilling Design Patterns From Agile Curation Case Studies

    NASA Astrophysics Data System (ADS)

    Benedict, K. K.; Lenhardt, W. C.; Young, J. W.

    2016-12-01

    In previous work the authors have argued that there is a need to take a new look at the data management lifecycle. Our core argument is that the data management lifecycle needs to be in essence deconstructed and rebuilt. As part of this process we also argue that much can be gained from applying ideas, concepts, and principles from agile software development methods. To be sure we are not arguing for a rote application of these agile software approaches, however, given various trends related to data and technology, it is imperative to update our thinking about how to approach the data management lifecycle, recognize differing project scales, corresponding variations in structure, and alternative models for solving the problems of scientific data curation. In this paper we will describe what we term agile curation design patterns, borrowing the concept of design patterns from the software world and we will present some initial thoughts on agile curation design patterns as informed by a sample of data curation case studies solicited from participants in agile data curation meeting sessions conducted in 2015-16.

  14. Contextualising experiences of depression in women from South Asian communities: a discursive approach.

    PubMed

    Burr, Jennifer; Chapman, Tom

    2004-05-01

    The aim of this paper is to present an interpretation of the accounts of depression provided by women from South Asian communities. The paper presents the findings from a qualitative study, conducted in the UK, which explored women from South Asian communities and their experiences of depression. It is argued here, through examples of women's accounts of their experiences, that depression is 'embodied', that is, grounded in the materiality of the body which is also immersed in subjective experiences and in the social context of women's lives. Qualitative data were collected from four focus groups and ten individual interviews with women. The analysis involved a discursive approach. Analysis revealed how women made strategic choices in how they presented their symptoms as legitimate and for gaining access to what they perceived to be appropriate healthcare. This is not to argue that this is a culturally specific phenomenon but one which is a feature of all healthcare negotiations.

  5. The Need for Systematic Reviews of Reasons

    PubMed Central

    Sofaer, Neema; Strech, Daniel

    2012-01-01

    There are many ethical decisions in the practice of health research and care, and in the creation of policy and guidelines. We argue that those charged with making such decisions need a new genre of review. The new genre is an application of the systematic review, which was developed over decades to inform medical decision-makers about what the totality of studies that investigate links between smoking and cancer, for example, implies about whether smoking causes cancer. We argue that there is a need for similarly inclusive and rigorous reviews of reason-based bioethics, which uses reasoning to address ethical questions. After presenting a brief history of the systematic review, we reject the only existing model for writing a systematic review of reason-based bioethics, which holds that such a review should address an ethical question. We argue that such a systematic review may mislead decision-makers when a literature is incomplete, or when there are mutually incompatible but individually reasonable answers to the ethical question. Furthermore, such a review can be written without identifying all the reasons given when the ethical questions are discussed, their alleged implications for the ethical question, and the attitudes taken to the reasons. The reviews we propose address instead the empirical question of which reasons have been given when addressing a specified ethical question, and present such detailed information on the reasons. We argue that this information is likely to improve decision-making, both directly and indirectly, and also the academic literature. We explain the limitations of our alternative model for systematic reviews. PMID:21521251

  8. Music and Early Language Acquisition

    PubMed Central

    Brandt, Anthony; Gebrian, Molly; Slevc, L. Robert

    2012-01-01

    Language is typically viewed as fundamental to human intelligence. Music, while recognized as a human universal, is often treated as an ancillary ability – one dependent on or derivative of language. In contrast, we argue that it is more productive from a developmental perspective to describe spoken language as a special type of music. A review of existing studies presents a compelling case that musical hearing and ability is essential to language acquisition. In addition, we challenge the prevailing view that music cognition matures more slowly than language and is more difficult; instead, we argue that music learning matches the speed and effort of language acquisition. We conclude that music merits a central place in our understanding of human development. PMID:22973254

  10. Best Practices for Gauging Evidence of Causality in Air Pollution Epidemiology.

    PubMed

    Dominici, Francesca; Zigler, Corwin

    2017-12-15

    The contentious political climate surrounding air pollution regulations has brought some researchers and policy-makers to argue that evidence of causality is necessary before implementing more stringent regulations. Recently, investigators in an increasing number of air pollution studies have purported to have used "causal analysis," generating the impression that studies not explicitly labeled as such are merely "associational" and therefore less rigorous. Using 3 prominent air pollution studies as examples, we review good practices for how to critically evaluate the extent to which an air pollution study provides evidence of causality. We argue that evidence of causality should be gauged by a critical evaluation of design decisions such as 1) what actions or exposure levels are being compared, 2) whether an adequate comparison group was constructed, and 3) how closely these design decisions approximate an idealized randomized study. We argue that air pollution studies that are more scientifically rigorous in terms of the decisions made to approximate a randomized experiment are more likely to provide evidence of causality and should be prioritized among the body of evidence for regulatory review accordingly. Our considerations, although presented in the context of air pollution epidemiology, can be broadly applied to other fields of epidemiology. © The Author(s) 2017.

  11. Epigenetics and the environment in bioethics.

    PubMed

    Dupras, Charles; Ravitsky, Vardit; Williams-Jones, Bryn

    2014-09-01

    A rich literature in public health has demonstrated that health is strongly influenced by a host of environmental factors that can vary according to social, economic, geographic, cultural or physical contexts. Bioethicists should, we argue, recognize this and--where appropriate--work to integrate environmental concerns into their field of study and their ethical deliberations. In this article, we present an argument grounded in scientific research at the molecular level that will be familiar to--and so hopefully more persuasive for--the biomedically-inclined in the bioethics community. Specifically, we argue that the relatively new field of molecular epigenetics provides novel information that should serve as additional justification for expanding the scope of bioethics to include environmental and public health concerns. We begin by presenting two distinct visions of bioethics: the individualistic and rights-oriented and the communitarian and responsibility-oriented. We follow with a description of biochemical characteristics distinguishing epigenetics from genetics, in order to emphasize the very close relationship that exists between the environment and gene expression. This then leads to a discussion of the importance of the environment in determining individual and population health, which, we argue, should shift bioethics towards a Potterian view that promotes a communitarian-based sense of responsibility for the environment, in order to fully account for justice considerations and improve public health. © 2012 John Wiley & Sons Ltd.

  14. The job of 'ethics committees'.

    PubMed

    Moore, Andrew; Donnelly, Andrew

    2015-11-13

    What should authorities establish as the job of ethics committees and review boards? Two answers are: (1) review of proposals for consistency with the duly established and applicable code and (2) review of proposals for ethical acceptability. The present paper argues that these two jobs come apart in principle and in practice. On grounds of practicality, publicity and separation of powers, it argues that the relevant authorities do better to establish code-consistency review and not ethics-consistency review. It also rebuts bad code and independence arguments for the opposite view. It then argues that authorities at present variously specify both code-consistency and ethics-consistency jobs, but most are also unclear on this issue. The paper then argues that they should reform the job of review boards and ethics committees, by clearly establishing code-consistency review and disestablishing ethics-consistency review, and through related reform of the basic orientation, focus, name, and expertise profile of these bodies and their actions.

  15. Looking forward, not back: Supporting structuralism in the present.

    PubMed

    McKenzie, Kerry

    2016-10-01

    The view that the fundamental kind properties are intrinsic properties enjoys reflexive endorsement by most metaphysicians of science. But ontic structural realists deny that there are any fundamental intrinsic properties at all. Given that structuralists distrust intuition as a guide to truth, and given that we currently lack a fundamental physical theory that we could consult instead to order settle the issue, it might seem as if there is simply nowhere for this debate to go at present. However, I will argue that there exists an as-yet untapped resource for arguing for ontic structuralism - namely, the way that fundamentality is conceptualized in our most fundamental physical frameworks. By arguing that physical objects must be subject to the 'Goldilock's principle' if they are to count as fundamental at all, I argue that we can no longer view the majority of properties defining them as intrinsic. As such, ontic structural realism can be regarded as the most promising metaphysics for fundamental physics, and that this is so even though we do not yet claim to know precisely what that fundamental physics is.

  19. To what extent do Gestalt grouping principles influence tactile perception?

    PubMed

    Gallace, Alberto; Spence, Charles

    2011-07-01

    Since their formulation by the Gestalt movement more than a century ago, the principles of perceptual grouping have primarily been investigated in the visual modality and, to a lesser extent, in the auditory modality. The present review addresses the question of whether the same grouping principles also affect the perception of tactile stimuli. Although, to date, only a few studies have explicitly investigated the existence of Gestalt grouping principles in the tactile modality, we argue that many more studies have indirectly provided evidence relevant to this topic. Reviewing this body of research, we argue that similar principles to those reported previously in visual and auditory studies also govern the perceptual grouping of tactile stimuli. In particular, we highlight evidence showing that the principles of proximity, similarity, common fate, good continuation, and closure affect tactile perception in both unimodal and crossmodal settings. We also highlight that the grouping of tactile stimuli is often affected by visual and auditory information that happen to be presented simultaneously. Finally, we discuss the theoretical and applied benefits that might pertain to the further study of Gestalt principles operating in both unisensory and multisensory tactile perception.

  20. Structural Equation Modeling: Applications in ecological and evolutionary biology research

    USGS Publications Warehouse

    Pugesek, Bruce H.; von Eye, Alexander; Tomer, Adrian

    2003-01-01

    This book presents an introduction to the methodology of structural equation modeling, illustrates its use, and goes on to argue that it has revolutionary implications for the study of natural systems. A major theme of this book is that we have, up to this point, attempted to study systems primarily using methods (such as the univariate model) that were designed only for considering individual processes. Understanding systems requires the capacity to examine simultaneous influences and responses. Structural equation modeling (SEM) has such capabilities. It also possesses many other traits that add strength to its utility as a means of making scientific progress. In light of the capabilities of SEM, it can be argued that much of ecological theory is currently locked in an immature state that impairs its relevance. It is further argued that the principles of SEM are capable of leading to the development and evaluation of multivariate theories of the sort vitally needed for the conservation of natural systems. Supplementary information can be found at the authors website, http://www.jamesbgrace.com/. • Details why multivariate analyses should be used to study ecological systems • Exposes unappreciated weakness in many current popular analyses • Emphasizes the future methodological developments needed to advance our understanding of ecological systems.

Using an auditory word-stem completion…

  14. Stochastic Convection Parameterizations: The Eddy-Diffusivity/Mass-Flux (EDMF) Approach (Invited)

    NASA Astrophysics Data System (ADS)

    Teixeira, J.

    2013-12-01

    In this presentation it is argued that moist convection parameterizations need to be stochastic in order to be realistic - even in deterministic atmospheric prediction systems. A new unified convection and boundary layer parameterization (EDMF) that optimally combines the Eddy-Diffusivity (ED) approach for smaller-scale boundary layer mixing with the Mass-Flux (MF) approach for larger-scale plumes is discussed. It is argued that for realistic simulations stochastic methods have to be employed in this new unified EDMF. Positive results from the implementation of the EDMF approach in atmospheric models are presented.

  15. John Dewey and the savage mind: uniting anthropological, psychological, and pedagogical thought, 1894-1902.

    PubMed

    Fallace, Thomas D

    2008-01-01

    In 1902 influential American philosopher John Dewey wrote a short essay on anthropolo-gists'view of the savage mind, arguing that it had had been unfairly dismissed as inchoate and incapable, when in fact the savage had much to teach scholars about the "present mind." The ideas presented in Dewey's essay were not only theoretical; they also served as the basis for his entire curriculum his famous laboratory school at the University of Chicago. Thus, the author argues that Dewey's pedagogical thought informed his anthropological thought, and vice versa.

  18. Milgram and Tuskegee--paradigm research projects in bioethics.

    PubMed

    Cave, Emma; Holm, Søren

    2003-03-01

    This paper discusses the use of the Milgram obedience experiments and the Tuskegee syphilis study in the bioethical literature. The two studies are presented and a variety of uses of them identified and discussed. It is argued that the use of these studies as paradigms of problematic research relies on a reduction of their complexity. What is discussed is thus often constructions of these studies that are closer to hypothetical examples than to the real studies.

  19. Call of the wild: the negative tendency in the nature religions of American youth.

    PubMed

    Kramp, Joseph M

    2015-02-01

    The author argues that the paucity of options for sanctioned rebellion in contemporary American society drive an ever-increasing number of idealistic youth in search of isolation in nature, where they construct what the author here calls "nature religions." These worldviews focus on purification of falsehood, ritualized through enduring extreme physical pain, social isolation, and extreme weather conditions in hopes of experiencing reality more authentically. The author argues that unemployment, limited vocational options, and the homogenization of American society are among the major catalysts for this ever-expanding breed of seekers, each of whom struggles with a negative tendency (a theoretical term created by Erik Erikson). Furthermore, the author argues that the emphasis in the nature religions on connection to nature is constructed to compensate for the lack of community and sense of human connectedness in contemporary American society. A representative case study from Jon Krakauer's (Into the wild; Doubleday, New York, 1996) Into the Wild is presented to illuminate and justify the argument made by the author for more institutionally housed options for sanctioned, licit rebellion to manage the negative tendency.

    ERIC Educational Resources Information Center

    Bizzell, Patricia

    2006-01-01

    Often, composition teachers present public debate as if it occurs on a rhetorically level playing field, with victory going to the person who argues most logically. Real-world contestants are seldom so equal in power. We can enrich our pedagogy by studying such encounters; example: the 1263 disputation at Barcelona between Rabbi Nachmanides and…

    Speelman and McGann’s (2013) examination of the uncritical way in which the mean is often used in psychological research raises questions both about the average’s reliability and its validity. In the present paper, we argue that interrogating the validity of the mean involves, amongst other things, a better understanding of the person’s experiences, the meaning of their actions, at the time that the behavior of interest is carried out. Recently emerging approaches within Psychology and Cognitive Science have argued strongly that experience should play a more central role in our examination of behavioral data, but the relationship between experience and behavior remains very poorly understood. We outline some of the history of the science on this fraught relationship, as well as arguing that contemporary methods for studying experience fall into one of two categories. “Wide” approaches tend to incorporate naturalistic behavior settings, but sacrifice accuracy and reliability in behavioral measurement. “Narrow” approaches maintain controlled measurement of behavior, but involve too specific a sampling of experience, which obscures crucial temporal characteristics. We therefore argue for a novel, mid-range sampling technique, that extends Hurlburt’s descriptive experience sampling, and adapts it for the controlled setting of the laboratory. This controlled descriptive experience sampling may be an appropriate tool to help calibrate both the mean and the meaning of an experimental situation with one another. PMID:27242588

  4. Questioning the significance of the non-identity problem in applied ethics.

    PubMed

    Lawlor, Rob

    2015-11-01

    Authors such as Tony Hope and Julian Savulescu appeal to Derek Parfit's non-identity problem in relation to particular questions in applied ethics, and particularly in reproductive ethics. They argue that the non-identity problem shows that an individual cannot be harmed by being brought into existence, and therefore, we cannot say that the individual is harmed if, for example, we select an embryo in order to have a deaf child. Thus, they argue that an appeal to the non-identity problem blocks (or significantly reduces the force of) objections in a number of cases. I argue that these discussions often give the impression that this is a clear conclusion, shared by most philosophers, and largely beyond dispute. This is particularly significant because these discussions are often in journals or books with an interdisciplinary readership. My concern is that they give the impression of stating: 'philosophers have studied this issue, and this is the conclusion they have reached. Now I will emphasise the implications for medical ethics'. I argue that, far from being the consensus view, the view presented by Hope and Savulescu is rejected by many, including Parfit himself. Published by the BMJ Publishing Group Limited.

  5. Can false memories be created through nonconscious processes?

    PubMed

    Zeelenberg, René; Plomp, Gijs; Raaijmakers, Jeroen G W

    2003-09-01

    Presentation times of study words presented in the Deese/Roediger and McDermott (DRM) paradigm varied from 20 to 2000 ms per word in an attempt to replicate the false memory effect following extremely short presentations reported by. Both in a within-subjects design (Experiment 1) and in a between-subjects design (Experiment 2) subjects showed memory for studied words as well as a false memory effect for related critical lures in the 2000-ms condition. However, in the conditions with shorter presentation times (20 ms in Experiment 1; 20 and 40 ms in Experiment 2) no memory for studied words, nor a false memory effect was found. We argue that there is at present no strong evidence supporting the claim for a nonconscious basis of the false memory effect.

  8. Cognitive science and the cultural nature of music.

    PubMed

    Cross, Ian

    2012-10-01

    The vast majority of experimental studies of music to date have explored music in terms of the processes involved in the perception and cognition of complex sonic patterns that can elicit emotion. This paper argues that this conception of music is at odds both with recent Western musical scholarship and with ethnomusicological models, and that it presents a partial and culture-specific representation of what may be a generic human capacity. It argues that the cognitive sciences must actively engage with the problems of exploring music as manifested and conceived in the broad spectrum of world cultures, not only to elucidate the diversity of music in mind but also to identify potential commonalities that could illuminate the relationships between music and other domains of thought and behavior.

  9. Using Theory of Mind to Promote Conceptual Change in Science

    NASA Astrophysics Data System (ADS)

    Kyriakopoulou, Natassa; Vosniadou, Stella

    2014-07-01

    We argue that learning science requires children to move from perceptually based representations to more abstract conceptual representations and to understand that appearance may sometimes deceive us and that the same phenomenon in the world can have more than one representation when seen from different perspectives. We also argue that the beginnings of such an epistemological perspective can be found in young children's ability to think about the difference between their beliefs and the beliefs of others in the social domain, i.e., their Theory of Mind. We present the results of two empirical studies that show significant correlations between children's growing Theory of Mind, developing epistemological thinking, and science learning, and suggest that Theory of Mind tasks can be used to promote conceptual change in science.

  10. Relocating alcohol advertising research: examining socially mediated relationships with alcohol.

    PubMed

    Cherrington, Jane; Chamberlain, Kerry; Grixti, Joe

    2006-03-01

    This article reviews, critiques and politicises the positivist approaches that presently dominate alcohol advertising health research, and considers the benefits of a culturalist alternative. Positivist research in this area is identified as: (1) atheoretical and methods-driven; (2) restricted in focus, leaving critical issues unconsidered; and (3) inappropriately conceptualizing the 'normal' drinking person as rational and safe. The culturist alternative proposed is argued to present a more adequate framework, which can include and address problematic issues that are presently excluded, including: the pleasures associated with alcohol use, the involvements of 'normal' people in problem drinking, the inadequacy of present risk categories and the complexities of wider mediatory processes about alcohol in society. We argue for the adoption of more informed, culturalist approaches to alcohol advertising research.

    2018-01-01

    The recent commentary paper by Ryding and Kaye Journal of Mental Health and Addictio n (doi 10.1007/s11469-017-9811-6, 2017) rightly claimed that "internet addiction" (IA) is a conceptual minefield and raised some important issues for researchers and treatment providers working in the online addiction field. In the present commentary paper, some of the assertions made by Ryding and Kaye are briefly critiqued and extended. More specifically, the present paper (i) examines IA and Internet-based addictions and argues that IA is now a misnomer, (ii) examines IA and its relationship to Internet Gaming Disorder (IGD) and argues IA and IGD are two completely different constructs, and that IGD is a sub-type of gaming disorder rather than a sub-type of IA, (iii) argues that the time spent engaging in online activities is not a good criterion for assessing online addictions and that the context of use is far more important criterion, and (iv) argues that those researchers working in the IA field can learn a lot from the problem gambling field in collecting robust data. More specifically, one of the innovative ways forward could be to build strategic partnerships with commercial online companies to analyze their behavioral tracking data.

    2007-01-01

    This presentation highlights the dimensions that organizational studies scholarship would highlight as being critical to furthering knowledge translation research. Attention is drawn to a number of dimensions of organizational complexity: knowledge translation as a processual phenomena, the contestability of knowledge, the existence and influence of multiple actors in healthcare contacts, the influence of professional and cognitive boundaries and the active role of context. It is argued that inclusion of such dimensions may enhance the impact of Estabrooks' work.

  7. Colouring in the "black-box": Alternative renderings of scientific visualisations in two comic book cosmologies.

    PubMed

    Locke, Simon

    2013-04-01

    Two somewhat contrasting views of public uses of scientific visualisations argue that they are "black-boxed" with meaning given by the scientific community or they are "polysemic" with meaning given by the context of presentation. This paper argues that whether they are treated as black-boxed or not and in what manner this is done is itself part of the meaning given by context. Thus, "black-boxing" is done not only by scientists but also by members of the public. The argument is illustrated by reference to two recent comic books, Dave Sim's Cerebus and Alan Moore's Promethea, in which the authors present cosmological visions of the universe using scientific visualisations to create a sense of realism. From analysis of their use of images of planet Earth and the human foetus it is argued that, although the images are black-boxed, the authors re-work them aesthetically to suit their specific moral and cosmological views.

    1998-02-01

    Two clinicians provided opposite answers to the title question: Persons argued that information from randomized controlled trials (RCTs) is vital to clinicians, and Silberschatz argued that information from RCTs is irrelevant to clinicians. Persons argued that clinicians cannot provide top quality care to their patients without attending to findings of RCTs and that clinicians have an ethical responsibility to inform patients about, recommend, and provide treatments supported by RCTs before informing patients about, recommending, and providing treatments shown to be inferior in RCTs or not evaluated in RCTs. Silberschatz argued that RCTs do not and cannot answer questions that concern practicing clinicians. He advocates alternative research approaches (effectiveness studies, quasi-experimental methods, case-specific research) for studying psychotherapy.

  9. Multistability in perception: binding sensory modalities, an overview.

    PubMed

    Schwartz, Jean-Luc; Grimault, Nicolas; Hupé, Jean-Michel; Moore, Brian C J; Pressnitzer, Daniel

    2012-04-05

    This special issue presents research concerning multistable perception in different sensory modalities. Multistability occurs when a single physical stimulus produces alternations between different subjective percepts. Multistability was first described for vision, where it occurs, for example, when different stimuli are presented to the two eyes or for certain ambiguous figures. It has since been described for other sensory modalities, including audition, touch and olfaction. The key features of multistability are: (i) stimuli have more than one plausible perceptual organization; (ii) these organizations are not compatible with each other. We argue here that most if not all cases of multistability are based on competition in selecting and binding stimulus information. Binding refers to the process whereby the different attributes of objects in the environment, as represented in the sensory array, are bound together within our perceptual systems, to provide a coherent interpretation of the world around us. We argue that multistability can be used as a method for studying binding processes within and across sensory modalities. We emphasize this theme while presenting an outline of the papers in this issue. We end with some thoughts about open directions and avenues for further research.

  11. The Rhetoric of Physics: AN Ethnography of the Research and Writing Processes in a Physics Laboratory.

    NASA Astrophysics Data System (ADS)

    Graves, Heather Ann Brodie

    1992-01-01

    This dissertation explores the extent to which rhetoric plays a role in the research and writing processes of physicists. It seeks to join the on-going conversation in the rhetoric of inquiry about the ways in which rhetorical forces shape all knowledge systems. Based on data collected during a six-month ethnography in a thin films laboratory, this study argues that these physicists use rhetoric in all stages of the knowledge creation process. After following the experimental process through all its stages from the inception of an experiment through to publication, this study maps out the types of heuristic devices employed by the physicists as they analyzed, interpreted, and presented their research data in a persuasive scientific article. In light of the insights gained from studying the dynamic interactions between physicists, this dissertation also comments on the theoretical and philosophical debates under discussion in the rhetoric of inquiry and the rhetoric of science. It examines current theories of language (as expressed by rhetoricians, critical theorists, and the physicists in this laboratory) to explore the relationship between reality and language, the role that rhetoric plays in knowledge creation in physics, and the ways in which reality and knowledge may be socially constructed. It concludes that these physicists use rhetorical invention strategies to interpret and present their data. It also argues that scientific knowledge is subject to rhetorical forces because it deals with contingent affairs--phenomena about which scientists advance propositions which appear to be true but about which there is no way to gain absolute certainty or truth. Finally, it concludes that rhetoric both is and is not epistemic in the physics research studied here, and it argues that instead of asking "Is rhetoric epistemic?" perhaps we might shift our attention to inquiring "When is rhetoric epistemic?".

  12. Reconsidering Kantian arguments against organ selling.

    PubMed

    Alpinar-Şencan, Zümrüt

    2016-03-01

    Referring to Kant's arguments addressing the moral relationship between our bodies and ourselves is quite common in contemporary debate about organ selling, although he does not provide us with any specific arguments related to this debate. It is widely argued that the most promising way to show the moral impermissibility of organ selling is to mount an argument on Kantian grounds. This paper asks whether it is possible to argue coherently against organ selling in a Kantian framework. It will be shown that by mounting the argument on Kantian grounds no compelling argument can be given against sale of organs, either because the arguments apply to donation of organs, too, or the arguments are not convincing for other independent reasons. In the first section, it will be argued that donation and selling are not distinguishable in a Kantian framework, since the concern about commodification of the body and its parts shall be raised by both actions. In the second section, some contemporary accounts inspired by Kant will be presented and discussed separately. It will be argued that the reasons for promoting organ donation while arguing against selling clash with each other in an unconvincing way.

  14. Commonalities between Perception and Cognition.

    PubMed

    Tacca, Michela C

    2011-01-01

    Perception and cognition are highly interrelated. Given the influence that these systems exert on one another, it is important to explain how perceptual representations and cognitive representations interact. In this paper, I analyze the similarities between visual perceptual representations and cognitive representations in terms of their structural properties and content. Specifically, I argue that the spatial structure underlying visual object representation displays systematicity - a property that is considered to be characteristic of propositional cognitive representations. To this end, I propose a logical characterization of visual feature binding as described by Treisman's Feature Integration Theory and argue that systematicity is not only a property of language-like representations, but also of spatially organized visual representations. Furthermore, I argue that if systematicity is taken to be a criterion to distinguish between conceptual and non-conceptual representations, then visual representations, that display systematicity, might count as an early type of conceptual representations. Showing these analogies between visual perception and cognition is an important step toward understanding the interface between the two systems. The ideas here presented might also set the stage for new empirical studies that directly compare binding (and other relational operations) in visual perception and higher cognition.

    This study aims to analyze the prior knowledge of students to map the level of skills to argue floating and sinking material. Prior knowledge is the process of concept formation in cognitive processes spontaneously or based on student experience. The study population is high school students of class XI. The sample selection using cluster random sampling, obtained the number of sampel as many as 50 student. The research used descriptive survey method. The data were obtained through a multiple choice test both grounded and interviewed. The data analyzed refers to: alignment the concept and the activity of developing the skill of the argument. The result obtained by the average level of skill argue in terms of the prior knowladge of on “Level 2”. The data show that students have difficulty expressing simple arguments consisting of only one statement. This indicates a lack of student experience in cultivating argumentative skills in their learning. The skill level mapping argued in this study to be a reference for researchers to provide feedback measures to obtain positive change in cognitive conflict argued.

  17. Microstructures and strain variation: Evidence of multiple splays in the North Almora Thrust Zone, Kumaun Lesser Himalaya, Uttarakhand, India

    2017-01-01

    The North Almora Thrust zone (NATZ) marks the boundary of the Almora Crystalline Complex (ACC) against the Lesser Himalayan Sedimentary sequence (LHS) in the north. Its southern counterpart, the South Almora Thrust (SAT), is a sharply marked contact between the ACC and the LHS in the south. Published studies argue various contradictory emplacement modes of the North Almora Thrust. Recent studies have implied splays of smaller back thrusts in the NATZ. The present study investigates meso- and microstructures, and strain distribution in the NATZ and compares it with strain distribution across the SAT. In the NATZ, field evidence reveals repeated sequence of 10-500 m thick slices of proto- to ultra-mylonite, thrust over the Lesser Himalayan Rautgara quartzite. In accordance with the field evidence, the strain analysis reveals effects of splays of smaller thrust in the NATZ. The study therefore, argues that contrary to popular nomenclature the northern contact of the ACC with the LHS is not a single thrust plane, but a thrust zone marked by numerous thrust splays.

    2016-01-01

    Emotional intelligence has been linked to various positive outcomes, such as organizational effectiveness, commitment, morale, and health. In addition, longitudinal studies demonstrate that the competencies of emotional intelligence may change and be developed over time. Researchers have argued that work relationships are important for the development of emotional competence, but their usefulness depends on the quality of the relationship. Workplace bullying is considered to be one of the most stressful phenomena in the workplace and an example of a dysfunctional and toxic relationship that has detrimental effects on an individual's physical and psychological health. Hence, the objective of the present study was to analyze the relationship linking workplace bullying, psychological distress and the self-management competence of emotional intelligence. More specifically, we tested part of the model presented by Cherniss and Goleman (2001) in which researchers argued that individual emotional intelligence is a result of relationships at work. In addition, we extended the model by proposing that the relationship between exposure to workplace bullying and the competence of self-management is explained by psychological distress. Data analysis of 326 participants from two private sector organizations in Italy demonstrated that psychological distress fully mediated the relationship between workplace bullying and the emotional intelligence ability of self-management. The present study's findings point to the idea that, not only may emotional intelligence assist in handling exposure to workplace bullying, but exposure to workplace bullying may impede emotional intelligence via psychological distress.

  19. Modalities of Generalization Through Single Case Studies.

    PubMed

    Zittoun, Tania

    2017-06-01

    The value of case studies for theory building is still doubted in psychology. The paper argues for the importance of case studies and the possibility of generalizing from these for a specific sociocultural understanding of human development. The paper first clarifies the notion of abduction within case studies, drawing on pragmatists James and Peirce and expanding it with the work of Lewin, and argues that it is the core mechanism that allows generalization from case studies. The second section presents the possibility of generalizing from individual single case studies, for which not only the subjective perspective, but also the dynamics by which the social and cultural environment guide and enable the person's development, have to be accounted for. The third section elaborates the question of institutional case studies, where the challenge is to account both for institutional dynamics, and for persons' trajectories within; this is exemplified with an ongoing study on the process of obtaining citizenship in Switzerland. The paper briefly concludes by highlighting two possible implications of the paper, one concerning the process of theoretical reasoning, the other, the fact that sociocultural psychology could itself be seen as an institution in-the-making.

    In Unfit for the Future, Ingmar Persson and Julian Savulescu argue that our collective existetial predicment is unprecedentedly dangerous due to climate change and terrorism. Given these global risks to human prosperity and survival, Persson and Savulescu argue that we should explore the radical possibility of moral bioenhancement in addition to cognitive enhancement. In this article, I argue that moral bioenhancements could nontrivially exacerbate the threat posed by certain kinds of malicious agents, while reducing the threat of other kinds. This introduces a previously undiscussed complication to Persson and Savulescu's proposal. In the final section, I present a novel argument for why moral bioenhancement should either be compulsory or not be made available to the public at all. © 2017 John Wiley & Sons Ltd.

  1. Summary and conclusions from the SIWI seminar for young water professionals water and sustainable development--how to ensure development without compromising sustainability?

    PubMed

    Johannessen, A

    2003-01-01

    There is a need to create a balance between development and conservation in order to find a way to mitigate the conflicting interest of water for society, the environment and the economy. Apart from finding a solution to this there is a need to get the mesaage across to the decision makers. How do we make good ideas permeate policy and translate into concrete programs? The Young Water Professionals gave their view through presentations and discussions. It was argued that the answer was not to be found only in environmental science but also in the political and social arena. It was argued that the sanctioned discourse is a powerful force in water allocation and management. How can a balance be struck? Many argued for a unique design of a policy for the whole catchment, acknowledging ecology and existing institutions. Furthermore, many argued in favor of building on existing institutions and steward groups for sustainability and increase their adaptive capacity.

  12. On the factorial and construct validity of the Intrinsic Motivation Inventory: conceptual and operational concerns.

    PubMed

    Markland, D; Hardy, L

    1997-03-01

    The Intrinsic Motivation Inventory (IMI) has been gaining acceptance in the sport and exercise domain since the publication of research by McAuley, Duncan, and Tammen (1989) and McAuley, Wraith, and Duncan (1991), which reported confirmatory support for the factorial validity of a hierarchical model of intrinsic motivation. Authors of the present study argue that the results of these studies did not conclusively support the hierarchical model and that the model did not accurately reflect the tenets of cognitive evaluation theory (Deci & Ryan, 1985) from which the IMI is drawn. It is also argued that a measure of perceived locus of causality is required to model intrinsic motivation properly. The development of a perceived locus of causality for exercise scale is described, and alternative models, in which perceived competence and perceived locus of causality are held to have causal influences on intrinsic motivation, are compared with an oblique confirmatory factor analytic model in which the constructs are held at the same conceptual level. Structural equation modeling showed support for a causal model in which perceived locus of causality mediates the effects of perceived competence on pressure-tension, interest-enjoyment, and effort-importance. It is argued that conceptual and operational problems with the IMI, as currently used, should be addressed before it becomes established as the instrument of choice for assessing levels of intrinsic motivation.

  13. Gender and work orientations in conditions of job insecurity.

    PubMed

    Charles, Nickie; James, Emma

    2003-06-01

    This paper explores women's and men's work orientations in conditions of job insecurity, arguing that it is time to move beyond essentalist conceptions of work orientations and central life interests in order to understand the significance of paid work in people's lives. Data from a qualitative study are presented which show that the significance of paid work and the priority given to home and work are affected by experiences of job insecurity, changing domestic circumstances and stage in the life cycle and that this is the case for both women and men. Conversely, the significance of paid work can affect how job insecurity is experienced and its impact on individuals and their families. The assumption that men's work orientations are homogeneous and that work is their central life interest is not supported by the findings presented here and it is argued that the significance of work in men's and women's lives is more variable than has hitherto been recognized. To capture this variability it is time to move away from the acrimony of the debate over women's work orientations and notions of a central life interest which underpin it.

  14. Science Pedagogy as a Category of Historical Analysis: Past, Present, and Future

    NASA Astrophysics Data System (ADS)

    Olesko, Kathryn M.

    2006-11-01

    Historical studies of science pedagogy have flourished in recent years. This essay offers an assessment of the literature on science pedagogy from the 1930s to the present. It argues that rather than focusing on the work of Thomas Kuhn and Michel Foucault, historians of science pedagogy could with profit turn to the work of Ludwik Fleck. Fleck offers three categories of historical analysis - experience, sensation, and cognition - that are embedded in science pedagogy. He furthermore argues unequivocally for the central importance of considering the cultural context of science pedagogy. Fleck’s interpretation of the role of publishing in science is used in the final section of this essay to assess scientific publishing and textbook culture, topics that are the principal concern of the articles in this volume. Among the novelties of the articles in this volume on textbooks are (1) the connections they draw between textbooks and social structure; (2) the relationships they suggest between textbooks and the public sphere; and (3) their identification of the eighteenth century as the crucial transformative century in textbook production.

  15. Small scale structure on cosmic strings

    NASA Technical Reports Server (NTRS)

    Albrecht, Andreas

    1989-01-01

    The current understanding of cosmic string evolution is discussed, and the focus placed on the question of small scale structure on strings, where most of the disagreements lie. A physical picture designed to put the role of the small scale structure into more intuitive terms is presented. In this picture it can be seen how the small scale structure can feed back in a major way on the overall scaling solution. It is also argued that it is easy for small scale numerical errors to feed back in just such a way. The intuitive discussion presented here may form the basis for an analytic treatment of the small scale structure, which argued in any case would be extremely valuable in filling the gaps in the present understanding of cosmic string evolution.

    2012-01-01

    Cognitive neuroscientists often study social cognition by using simple but socially relevant stimuli, such as schematic faces or images of other people. Whilst this research is valuable, important aspects of genuine social encounters are absent from these studies, a fact that has recently drawn criticism. In the present review we argue for an empirical approach to the determination of the equivalence of different social stimuli. This approach involves the systematic comparison of different types of social stimuli ranging in their approximation to a real social interaction. In garnering support for this cognitive ethological approach, we focus on recent research in social attention that has involved stimuli ranging from simple schematic faces to real social interactions. We highlight both meaningful similarities and differences in various social attentional phenomena across these different types of social stimuli thus validating the utility of the research initiative. Furthermore, we argue that exploring these similarities and differences will provide new insights into social cognition and social neuroscience. PMID:22654747

    2018-05-01

    The study of free fall is thoroughly present in physics teaching at all levels. From the point of view of Newtonian dynamics it appears to be extremely simple, as it consists of a two-body problem with a constant force generating a constant acceleration. However, there are several important conceptual subtleties and hidden assumptions involved in this problem, which are rarely discussed in educational settings. In this work we present some of these subtleties and argue that explicitly addressing them has significant pedagogical benefits.

    2010-01-01

    The polarization plane of the cosmic microwave background radiation (CMBR) can be rotated either in a space-time with metric of anisotropic type and in a magnetized plasma or in the presence of a quintessential background with pseudoscalar coupling to electromagnetism. A unified treatment of these three phenomena is presented for cold anisotropic plasma at the pre-recombination epoch. It is argued that the generalized expressions derived in the present study may be relevant for direct searches of a possible rotation of the cosmic microwave background polarization.

  20. Slavery and jouissance: analysing complaints of suffering in UK and Australian nurses' talk about their work.

    PubMed

    Traynor, Michael; Evans, Alicia

    2014-07-01

    Nursing has a gendered and religious history where ideas of duty and servitude are present and shape its professional identity. The profession also promotes idealized notions of relationships with patients and of professional autonomy both of which are, in practice, highly constrained or even impossible. This paper draws on psychoanalytic concepts in order to reconsider nursing's professional identity. It does this by presenting an analysis of data from two focus group studies involving nurses in England and Australia held between 2010 and 2012. The studies gave rise to data where extremely negative talk about nursing work seemed to produce, or to be expressed with, a high degree of energy, and a particular kind of enjoyment. In our analysis, we focus on the nurses' apparent enjoyment derived from their expression of a position of powerlessness in which they describe themselves as 'slaves' or 'martyrs' in the health care system. We interpret this as jouissance and suggest that the positions of slave or martyr provide a possible response to what we argue is the impossibility of the nurse's role. We argue that a remnant of a quasi-religious ethic within the profession makes it acceptable for nurses to talk about self-sacrifice and powerlessness as part of their working subjectivity. We further argue that this analysis offers a new consideration of the issue of power and professional identity in nursing that goes beyond seeing nurses as simply overpowered by, or engaged in, a gendered power struggle with other professional groups. We suggest that powerlessness and victimhood hold particular attractions and advantages for nurses and are positions that are more available to nurses than to other occupational groups. This research shows how psychoanalytic theory can help produce new insights into the problems and complexity of nursing and extend existing study of the professions. © 2014 John Wiley & Sons Ltd.

    Gilbert Ryle's (1949) and Ludwig Wittgenstein's (1953; 1958; 1974/78) conceptual analyses of verbal understanding are presented. For Ryle, the term understanding signifies simultaneously an acquired disposition and a behavioral episode. For Wittgenstein, it signifies simultaneously a skill and a criterial behavior. Both argued that episodes of understanding comprise heterogenious classes of behaviors, and that each member of such a class is neither a necessary nor a sufficient condition of understanding. Next, an approach integrating the analyses of Ryle and Wittgenstein with that of Skinner is presented. Lastly, it is argued that this integrated analysis adequately counters Parrott's (1984) argument that understanding, for Skinner, is potential behavior and not an event.

    A detailed model for a photospheric dynamo has been presented by Henoux and Somov (1987), who used the three-fluid model to treat the properties of the weakly ionized plasma. Only the equations for the two ionized components were solved. The equation for the neutral component is considered, and it is argued that the model is unacceptable becaused of an implied impossibly large unbalanced stress on the neutral gas. It is argued more generally that all existing photospheric dynamo models are untenable.

    In this paper, I will argue that, while the ethical issues raised by cluster randomization can be challenging, they are not new. My thesis divides neatly into two parts. In the first, easier part I argue that many of the ethical challenges posed by cluster randomized human subjects research are clearly present in other types of human subjects research, and so are not novel. In the second, more difficult part I discuss the thorniest ethical challenge for cluster randomized research--cases where consent is genuinely impractical to obtain. I argue that once again these cases require no new analytic insight; instead, we should look to political philosophy for guidance. In other words, the most serious ethical problem that arises in cluster randomized research also arises in political philosophy. © 2011 Blackwell Publishing Ltd.

  12. Navigating the Complexity of Socio-scientific Controversies—How Students Make Multiple Voices Present in Discourse

    NASA Astrophysics Data System (ADS)

    Solli, Anne; Hillman, Thomas; Mäkitalo, Åsa

    2017-10-01

    In this article, we argue that students' unfolding discourse on socio-scientific issues (SSI) can be fruitfully analyzed by using dialogical theories of language and communication (Bakhtin 1986; Linell 2009). While research in science education often reports on how individual reasoning changes when bringing SSI into the classroom, we argue for the relevance of analyzing how the individual is "in dialogue" with present as well as remote interlocutors and contexts on the internet. We suggest that the analytical approach is particularly sensitized to illuminate how students' handle multiple perspectives. A dialogical perspective takes as its premise that SSI are part of society, where politicians, interest groups, and scientists engage in debates and offer perspectives that are often in conflict. Rather than assuming that the individual student is the primary unit for analysis, a dialogical approach is premised on an analysis that incorporates several perspectives and voices—a multivocality that also resides with the individual. Arguing for the relevance of this analytical approach to studies of SSI in the classroom, we analyze a group of students in upper secondary school as they discuss hydraulic fracturing after having worked with online data. The results illuminate how students discursively manage multivocality and multimodality inherent in the following SSI online. We describe a set of discursive means that the students use to handle the many perspectives involved when communicating about the issue. In addition, we describe and articulate what kind of communicative competences that are involved and, hence, could be cultivated through education, when engaging in public debates.

  13. Psychological Science within a Three-Dimensional Ontology.

    PubMed

    Lundh, Lars-Gunnar

    2018-03-01

    The present paper outlines the nature of a three-dimensional ontology and the place of psychological science within this ontology, in a way that is partly similar to and partly different from that of Pérez-Álvarez. The first dimension is the material realities, and involves different levels (physical, chemical, biological, psychological, etc.), where each level builds on a lower level but also involves the development of new emergent properties, in accordance with Bunge's emergent materialism. Each level involves systems, with components, structures and mechanisms, and an environment. This dimension can be studied with natural scientific methods. The second dimension is the subjective-experiential realities, and refers to our subjective perspective on the world. In accordance with Husserl's phenomenology, it is argued that this subjectivity does not exist in the world (i.e., should not be reified as an object among other objects), but represents a perspective on the world that we enter in our capacity as conscious human beings. Essential characteristics of this subjectivity (such as intentionality, temporality, embodiment, and intersubjectivity) can be explored by phenomenological methods. The third dimension is the social-constructional realities, and includes social institutions, norms, categories, theories, and techniques. It is argued that psychological science spans over all three dimensions. Although almost all psychological research by necessity starts from a problem formulation where the subjective-experiential dimension plays an essential role (either explicitly or implicitly), most of present-day psychological research clearly emphasizes the material dimension. It is argued that a mature psychological science needs to integrate all three dimensions.

  14. The influence of dynamical friction and mean motion resonances on terrestrial planet growth

    NASA Astrophysics Data System (ADS)

    Wallace, Spencer Clark; Quinn, Thomas R.

    2018-04-01

    We present a set of high-resolution direct N-body simulations of planetesimal coagulation at 1 AU. We follow the evolution of of 1 million planetesimals in a ring though the runaway and oligarchic growth phases. During oligarchic growth, the size frequency distribution (SFD) of planetesimals develops a bump at intermediate masses, which we argue is due to dynamical friction acting through mean motion resonances, heating the low mass planetesimals and inhibiting their growth. This feature is similar to the bump seen in the SFD of asteroid belt and Kuiper belt objects and we argue that a careful treatment of the dynamics of planetesimal interactions is required in order to adequately explain the observed SFD. Although our model does not account for fragmentation, our results show that a similar feature can be produced without it, which is in contention with previous studies.

  15. The string soundscape at gravitational wave detectors

    NASA Astrophysics Data System (ADS)

    Garcia Garcia, Isabel; Krippendorf, Sven; March-Russell, John

    2018-04-01

    We argue that gravitational wave signals due to collisions of ultra-relativistic bubble walls may be common in string theory. This occurs due to a process of post-inflationary vacuum decay via quantum tunnelling. Though we study a specific string construction involving warped throats, we argue that our conclusions are more general. Many such transitions could have occurred in the post-inflationary Universe, as a large number of throats with exponentially different mass scales can be present in the string landscape, leading to several signals of widely different frequencies - a soundscape connected to the landscape of vacua. Detectors such as aLIGO/VIRGO, LISA, and pulsar timing observations with SKA and EPTA have the sensitivity to detect such signals. A distribution of primordial black holes is also a likely consequence, though reliable estimates of masses and their abundance require dedicated numerical simulations, as do the fine details of the gravitational wave spectrum due to the unusual nature of the transition.

  16. Naturalizing aesthetics: brain areas for aesthetic appraisal across sensory modalities.

    PubMed

    Brown, Steven; Gao, Xiaoqing; Tisdelle, Loren; Eickhoff, Simon B; Liotti, Mario

    2011-09-01

    We present here the most comprehensive analysis to date of neuroaesthetic processing by reporting the results of voxel-based meta-analyses of 93 neuroimaging studies of positive-valence aesthetic appraisal across four sensory modalities. The results demonstrate that the most concordant area of activation across all four modalities is the right anterior insula, an area typically associated with visceral perception, especially of negative valence (disgust, pain, etc.). We argue that aesthetic processing is, at its core, the appraisal of the valence of perceived objects. This appraisal is in no way limited to artworks but is instead applicable to all types of perceived objects. Therefore, one way to naturalize aesthetics is to argue that such a system evolved first for the appraisal of objects of survival advantage, such as food sources, and was later co-opted in humans for the experience of artworks for the satisfaction of social needs.

    2001-08-01

    The purpose of this article is to report our findings from a qualitative study intended to develop our understandings of how inner-city mothers perceive science. Using qualitative methodologies, our analysis reveals that the mothers' perceptions can be grouped into four categories: perceptions of science as (a) schoolwork/knowledge, (b) fun projects, (c) a tool for maintaining the home and family, and (d) an untouchable domain. After we present these categories we compare our findings across categories to argue that those mothers who had spent time doing science with their children were more likely to have a more personal, dynamic, and inquiry-based view of science. We also argue that mothers' perceptions of science were more dynamic when they spoke about situations and contexts that were familiar to them, such as food, nutrition, and child care. We conclude the article with a discussion of the implications our findings have for science education reform.

  18. So what exactly is nursing knowledge?

    PubMed

    Clarke, L

    2011-06-01

    This paper aims to present a discussion about intrinsic nursing knowledge. The paper stems from the author's study of knowledge claims enshrined in nursing journal articles, books and conference speeches. It is argued that claims by academic nurses have largely depended on principles drawn from continental and not Analytic (British-American) philosophy. Thus, claims are credible only insofar as they defer propositional logic. This is problematic inasmuch as nursing is a practice-based activity usually carried out in medical settings. Transpersonal nursing models are particularly criticizable in respect of their unworldly character as are also concepts based on shallow usages of physics or mathematics. I argue that sensible measurements of the 'real world' are possible--without endorsing positivism--and that nursing requires little recourse to logically unsustainable claims. The paper concludes with an analysis of a recent review of nursing knowledge, which analysis indicates the circularity that attends many discussions on the topic. © 2011 Blackwell Publishing.

    Data sculptures are a promising type of visualizations in which data is given a physical form. In the past, they have mostly been used for artistic, communicative or educational purposes, and designers of data sculptures argue that in such situations, physical visualizations can be more enriching than pixel-based visualizations. We present the design of Activity Sculptures: data sculptures of running activity. In a three-week field study we investigated the impact of the sculptures on 14 participants' running activity, the personal and social behaviors generated by the sculptures, as well as participants' experiences when receiving these individual physical tokens generated from the specific data of their runs. The physical rewards generated curiosity and personal experimentation but also social dynamics such as discussion on runs or envy/competition. We argue that such passive (or calm) visualizations can complement nudging and other mechanisms of persuasion with a more playful and reflective look at ones' activity.

  1. Habituation of reinforcer effectiveness

    2014-01-01

    In this paper we propose an integrative model of habituation of reinforcer effectiveness (HRE) that links behavioral- and neural-based explanations of reinforcement. We argue that HRE is a fundamental property of reinforcing stimuli. Most reinforcement models implicitly suggest that the effectiveness of a reinforcer is stable across repeated presentations. In contrast, an HRE approach predicts decreased effectiveness due to repeated presentation. We argue that repeated presentation of reinforcing stimuli decreases their effectiveness and that these decreases are described by the behavioral characteristics of habituation (McSweeney and Murphy, 2009; Rankin etal., 2009). We describe a neural model that postulates a positive association between dopamine neurotransmission and HRE. We present evidence that stimulant drugs, which artificially increase dopamine neurotransmission, disrupt (slow) normally occurring HRE and also provide evidence that stimulant drugs have differential effects on operant responding maintained by reinforcers with rapid vs. slow HRE rates. We hypothesize that abnormal HRE due to genetic and/or environmental factors may underlie some behavioral disorders. For example, recent research indicates that slow-HRE is predictive of obesity. In contrast ADHD may reflect “accelerated-HRE.” Consideration of HRE is important for the development of effective reinforcement-based treatments. Finally, we point out that most of the reinforcing stimuli that regulate daily behavior are non-consumable environmental/social reinforcers which have rapid-HRE. The almost exclusive use of consumable reinforcers with slow-HRE in pre-clinical studies with animals may have caused the importance of HRE to be overlooked. Further study of reinforcing stimuli with rapid-HRE is needed in order to understand how habituation and reinforcement interact and regulate behavior. PMID:24409128

  3. Contextualizing neuro-collaborations: reflections on a transdisciplinary fMRI lie detection experiment

    2014-01-01

    Recent neuroscience initiatives (including the E.U.’s Human Brain Project and the U.S.’s BRAIN Initiative) have reinvigorated discussions about the possibilities for transdisciplinary collaboration between the neurosciences, the social sciences, and the humanities. As STS scholars have argued for decades, however, such inter- and transdisciplinary collaborations are potentially fraught with tensions between researchers. This essay build on such claims by arguing that the tensions of transdisciplinary research also exist within researchers’ own experiences of working between disciplines - a phenomenon that we call “disciplinary double consciousness” (DDC). Building on previous work that has characterized similar spaces (and especially on the Critical Neuroscience literature), we argue that “neuro-collaborations” inevitably engage researchers in DDC - a phenomenon that allows us to explore the useful dissonance that researchers can experience when working between a “home” discipline and a secondary discipline. Our case study is a five-year research project in functional magnetic resonance imaging (fMRI) lie detection involving a transdisciplinary research team made up of social scientists, a neuroscientist, and a humanist. In addition to theorizing neuro-collaborations from the inside-out, this essay presents practical suggestions for developing transdisciplinary infrastructures that could support future neuro-collaborations.

    2000-08-01

    Data collected during the Meteorite Observation and Recovery Program (MORP) indicate that 4% of bright fireballs show a periodic variation or flickering in brightness. The observed flickering frequencies vary from a few Hz to as high as 500 Hz. We interpret the flickering phenomenon in terms of meteoroid rotation. The MORP data does not reveal any apparent correlation between the flickering frequency and the properties of the meteoroid or the atmospheric flow conditions under which ablation is taking place. It is argued that the most likely cause of the flickering phenomenon is the rotational modulation of the cross-section area presented by the meteoroid to the on-coming airflow. A study is made of the Peekskill fireball and it is concluded that the meteoroid was spun-up during its long flight through the Earth's atmosphere, and that its initial brake up was due to rotational bursting. We also argue that the Peekskill event provides the best observational evidence that the flickering phenomenon is truly related to the rotation rate of the impinging meteoroid. We find that the observed rotation rates of the MORP fireballs are clustered just below the allowed limit set by rotational bursting, but argue that this is due to an observational selection effect that mitigates against the detection of low-frequency flickering.

    Emotional intelligence has been linked to various positive outcomes, such as organizational effectiveness, commitment, morale, and health. In addition, longitudinal studies demonstrate that the competencies of emotional intelligence may change and be developed over time. Researchers have argued that work relationships are important for the development of emotional competence, but their usefulness depends on the quality of the relationship. Workplace bullying is considered to be one of the most stressful phenomena in the workplace and an example of a dysfunctional and toxic relationship that has detrimental effects on an individual’s physical and psychological health. Hence, the objective of the present study was to analyze the relationship linking workplace bullying, psychological distress and the self-management competence of emotional intelligence. More specifically, we tested part of the model presented by Cherniss and Goleman (2001) in which researchers argued that individual emotional intelligence is a result of relationships at work. In addition, we extended the model by proposing that the relationship between exposure to workplace bullying and the competence of self-management is explained by psychological distress. Data analysis of 326 participants from two private sector organizations in Italy demonstrated that psychological distress fully mediated the relationship between workplace bullying and the emotional intelligence ability of self-management. The present study’s findings point to the idea that, not only may emotional intelligence assist in handling exposure to workplace bullying, but exposure to workplace bullying may impede emotional intelligence via psychological distress.

    The presentation discusses the need of developing a new area of scientific study, namely the "Sociology of Energy Development". It presents our knowledge gaps, regarding the reaction of societies towards energy projects. The presentation proposes that the first steps will be to study the "ethnography" of the energy companies and acquire a clear understanding of their specific cultures. In particular, the presentation argues for a need to raise meaningful questions about the values and attitudes of energy companies in areas such as environmental awareness; gender; cultural differences and other issues of conflict. It will also propose that a new conceptual framework is developed for the specific analysis of the relationship between society and energy companies, in the fields of public perception and trust. Finally, the presentation will conclude with an exploration of key principles, which may guide the development of new ethical practices in the field of energy.

    This note first presents a summary of four main behavioral models that are used to explain behavioral motivation and change. Three models are based on psychosocial theory. They are: 1) the Theory of Reasoned Action, 2) the Theory of Planned Behavior, and 3) the Theory of Stages-of-Change. The fourth model is based on economic theory and is known as the Rational Addiction Model. Each model is analyzed for its strengths and weaknesses. The note concludes by arguing for the usefulness of integrating the economic and the psychosocial models to study drug use. Specific examples and suggestions are presented.

    Using data from a case study presented in Chiat (1989), Marshall and Chiat (2003) compare two different approaches to account for the realization of intervocalic consonants in child phonology: "coda capture theory" and the "foot domain account". They argue in favour of the latter account. In this note, we present a reappraisal of this argument using the same data. We conclude that acceptance of the foot domain account, in the specific way developed by the authors, is unmotivated for both theoretical and empirical reasons. We maintain that syllable-based coda capture is (still) the better approach to account for the relevant facts.

  11. Contemplative Neuroscience as an Approach to Volitional Consciousness

    NASA Astrophysics Data System (ADS)

    Thompson, Evan

    This chapter presents a methodological approach to volitional consciousness for cognitive neuroscience based on studying the voluntary self-generation and self-regulation of mental states in meditation. Called contemplative neuroscience, this approach views attention, awareness, and emotion regulation as flexible and trainable skills, and works with experimental participants who have undergone training in contemplative practices designed to hone these skills. Drawing from research on the dynamical neural correlates of contemplative mental states and theories of large-scale neural coordination dynamics, I argue for the importance of global system causation in brain activity and present an "interventionist" approach to intentional causation.

  14. Picking Up Artifacts: Storyboarding as a Gateway to Reuse

    Wahid, Shahtab; Branham, Stacy M.; Cairco, Lauren; McCrickard, D. Scott; Harrison, Steve

    Storyboarding offers designers the opportunity to illustrate a visual narrative of use. Because designers often refer to past ideas, we argue storyboards can be constructed by reusing shared artifacts. We present a study in which we explore how designers reuse artifacts consisting of images and rationale during storyboard construction. We find images can aid in accessing rationale and that connections among features aid in deciding what to reuse, creating new artifacts, and constructing. Based on requirements derived from our findings, we present a storyboarding tool, PIC-UP, to facilitate artifact sharing and reuse and evaluate its use in an exploratory study. We conclude with remarks on facilitating reuse and future work.

    We present a Monte Carlo method that allows efficient and unbiased sampling of Hamiltonian walks on a cubic lattice. Such walks are self-avoiding and visit each lattice site exactly once. They are often used as simple models of globular proteins, upon adding suitable local interactions. Our algorithm can easily be equipped with such interactions, but we study here mainly the flexible homopolymer case where each conformation is generated with uniform probability. We argue that the algorithm is ergodic and has dynamical exponent z=0. We then use it to study polymers of size up to 643=262144 monomers. Results are presented for the effective interaction between end points, and the interaction with the boundaries of the system.

  16. Extracommunicative functions of language: verbal interference causes selective categorization impairments.

    PubMed

    Lupyan, Gary

    2009-08-01

    In addition to its communicative functions, language has been argued to have a variety of extracommunicative functions, as assessed by its causal involvement in putatively nonlinguistic tasks. In the present work, I argue that language may be critically involved in the ability of human adults to categorize objects on a specific dimension (e.g., color) while abstracting over other dimensions (e.g., size). This ability is frequently impaired in aphasic patients. The present work demonstrates that normal participants placed under conditions of verbal interference show a pattern of deficits strikingly similar to that of aphasic patients: impaired taxonomic categorization along perceptual dimensions, and preserved thematic categorization. A control experiment using a visuospatial-interference task failed to find this selective pattern of deficits. The present work has implications for understanding the online role of language in normal cognition and supports the claim that language is causally involved in nonverbal cognition.

  17. Setting an Agenda to Address Intimate Partner Violence Among Young Men Who Have Sex With Men: A Conceptual Model and Review.

    PubMed

    Kubicek, Katrina

    2016-10-18

    Research investigating intimate partner violence (IPV) among sexual minorities is limited. The research that does exist has found that rates of IPV are similar to or higher than the rates found for heterosexual women, the most commonly studied population in this area. This limited research has resulted in a dearth of prevention/intervention programs targeted for these populations. While some may argue that existing IPV programs can be used for these populations, this review presents an argument for more targeted work with sexual minority populations, using young men who have sex with men (YMSM) as an example. Drawing on the framework of intersectionality, this article argues that the intersectionality of age, sexual identity, and gender combines to create a spectrum of unique factors that require specific attention. This framework allows for the identification of known correlates for IPV as well as factors that may be unique to YMSM or other sexual minority populations. The article presents a conceptual model that suggests new areas of research as well as a foundation for the topics and issues that should be addressed in an intervention. © The Author(s) 2016.

    Despite nearly two decades of research on mirror neurons, there is still much debate about what they do. The most enduring hypothesis is that they enable ‘action understanding’. However, recent critical reviews have failed to find compelling evidence in favour of this view. Instead, these authors argue that mirror neurons are produced by associative learning and therefore that they cannot contribute to action understanding. The present opinion piece suggests that this argument is flawed. We argue that mirror neurons may both develop through associative learning and contribute to inferences about the actions of others.

    Parkinson disease (PD) is not an unambiguous entity, and there is a general consensus for the statement that an akinetic-rigid dominant type of presentation has a worse prognosis, in the follow-up. The aim of our study was to examine the differences in frontal tasks and behavior, in 2 PD naive groups: the rigid and the tremor-dominant types of presentation, according to motor scores. Our study has showed some important differences in frontal tasks and in behavior, performing more apathy, aggressiveness, and irritability in the rigid type, and more depression and anxiety in the tremor-dominant type. The former group causes the caregiver more distress and has a very rapid disease progression. It can be argued that rigid type PD presentation needs specific dedicated cares and more strong clinical attention.

    PubMed

    Kawamoto, Alan H; Liu, Qiang; Kello, Christopher T

    2015-01-01

    Speech production and reading aloud studies have much in common, especially the last stages involved in producing a response. We focus on the minimal planning unit (MPU) in articulation. Although most researchers now assume that the MPU is the syllable, we argue that it is at least as small as the segment based on negative response latencies (i.e., response initiation before presentation of the complete target) and longer initial segment durations in a reading aloud task where the initial segment is primed. We also discuss why such evidence was not found in earlier studies. Next, we rebut arguments that the segment cannot be the MPU by appealing to flexible planning scope whereby planning units of different sizes can be used due to individual differences, as well as stimulus and experimental design differences. We also discuss why negative response latencies do not arise in some situations and why anticipatory coarticulation does not preclude the segment MPU. Finally, we argue that the segment MPU is also important because it provides an alternative explanation of results implicated in the serial vs. parallel processing debate.

  5. Critical realism: a practical ontology to explain the complexities of smoking and tobacco control in different resource settings

    2013-01-01

    Background This paper presents critical realism (CR) as an innovative system for research in tobacco prevention and control. CR argues that underlying mechanisms are considered and explored to ensure effective implementation of any program/policy or intervention. Any intervention or program/policy that is transposed from one country to another or one setting to another is complex. Methods The research was undertaken and analyzed through a critical ethnography lens using CR as a philosophical underpinning. The study relied upon the following components: original fieldwork in Nigeria including participant observation of smokers, in-depth interviews and focus groups with smokers, and in-depth interviews with health professionals working in the area of tobacco control in Nigeria. Results Findings from this small ethnographic study in Nigeria, suggest that Critical Realism holds promise for addressing underlying mechanism that links complex influences on smoking. Conclusion This paper argues that understanding the underlying mechanisms associated with smoking in different societies will enable a platform for effective implementation of tobacco control policies that work in various settings.

  6. Temporal naturalism

    NASA Astrophysics Data System (ADS)

    Smolin, Lee

    2015-11-01

    Two people may claim both to be naturalists, but have divergent conceptions of basic elements of the natural world which lead them to mean different things when they talk about laws of nature, or states, or the role of mathematics in physics. These disagreements do not much affect the ordinary practice of science which is about small subsystems of the universe, described or explained against a background, idealized to be fixed. But these issues become crucial when we consider including the whole universe within our system, for then there is no fixed background to reference observables to. I argue here that the key issue responsible for divergent versions of naturalism and divergent approaches to cosmology is the conception of time. One version, which I call temporal naturalism, holds that time, in the sense of the succession of present moments, is real, and that laws of nature evolve in that time. This is contrasted with timeless naturalism, which holds that laws are immutable and the present moment and its passage are illusions. I argue that temporal naturalism is empirically more adequate than the alternatives, because it offers testable explanations for puzzles its rivals cannot address, and is likely a better basis for solving major puzzles that presently face cosmology and physics. This essay also addresses the problem of qualia and experience within naturalism and argues that only temporal naturalism can make a place for qualia as intrinsic qualities of matter.

    This article addresses the conduct of qualitative research regarding sensitive or stigmatizing topics with military populations, and provides suggestions for implementing culturally responsive and effective data collection with these groups. Given high rates of underreporting of sensitive and stigmatizing conditions in the military, qualitative methods have potential to shed light on phenomena that are not well understood.

  11. On the genetic modification of psychology, personality, and behavior.

    PubMed

    Neitzke, Alex B

    2012-12-01

    I argue that the use of heritable modifications for psychology, personality, and behavior should be limited to the reversal or prevention of relatively unambiguous instances of pathology or likely harm (e.g. sociopathy). Most of the likely modifications of psychological personality would not be of this nature, however, and parents therefore should not have the freedom to make such modifications to future children. I argue by examining the viewpoints of both the individual and society. For individuals, modifications would interfere with their capacity for self-determination in a way that undermines the very concept of self-determination. I argue that modification of psychology and personality is unlike present parenting in morally significant ways. For society, modification offers a medium for power to manipulate the makeup of persons and populations, possibly causing biological harm to the species and altering our conceptions of social responsibility.

  12. Learning from Inconsistency

    NASA Technical Reports Server (NTRS)

    Easterbrook, Steve

    1996-01-01

    This position paper argues that inconsistencies that occur during the development of a software specification offer an excellent way of learning more about the development process. We base this argument on our work on inconsistency management. Much attention has been devoted recently to the need to allow inconsistencies to occur during software development, to facilitate flexible development strategies, especially for collaborative work. Recent work has concentrated on reasoning in the presence of inconsistency, tracing inconsistencies with 'pollution markers' and supporting resolution. We argue here that one of the most important aspects of inconsistency is the learning opportunity it provides. We are therefore concerned with how to capture this learning outcome so that its significance is not lost. We present a small example of how apprentice software engineers learn from their mistakes, and outline how an inconsistency management tool could support this learning. We then argue that the approach can be used more generally as part of continuous process improvement.

    Evans, Jonathan St B T; Over, David E

    2010-05-01

    Marewski, Gaissmaier and Gigerenzer (2009) present a review of research on fast and frugal heuristics, arguing that complex problems are best solved by simple heuristics, rather than the application of knowledge and logical reasoning. We argue that the case for such heuristics is overrated. First, we point out that heuristics can often lead to biases as well as effective responding. Second, we show that the application of logical reasoning can be both necessary and relatively simple. Finally, we argue that the evidence for a logical reasoning system that co-exists with simpler heuristic forms of thinking is overwhelming. Not only is it implausible a priori that we would have evolved such a system that is of no use to us, but extensive evidence from the literature on dual processing in reasoning and judgement shows that many problems can only be solved when this form of reasoning is used to inhibit and override heuristic thinking.

    In this paper, we study spreading of two cooperative SIS epidemics in mean field approximations and also within an agent based framework. Therefore we investigate dynamics on different topologies like Erdos-Renyi networks and regular lattices. We show that cooperativity of two diseases can lead to strongly first order outbreaks, while the dynamics still might present some scaling laws typical for second order phase transitions. We argue how topological network features might be related to this interesting hybrid behaviors.

  15. Ecology. Three-Gorges Dam--experiment in habitat fragmentation?

    Habitat fragmentation is the primary cause of the loss of biodiversity and ecosystem services, but its underlying processes and mechanisms remain poorly understood. Studies of islands and insular terrestrial habitats are essential for improving our understanding of habitat fragmentation. We argue that the Three-Gorges Dam, the largest that humans have ever created, presents a unique grand-scale natural experiment that allows ecologists to address a range of critical questions concerning the theory and practice of biodiversity conservation.

  16. Changing predictions, stable recognition: Children's representations of downward incline motion.

    PubMed

    Hast, Michael; Howe, Christine

    2017-11-01

    Various studies to-date have demonstrated children hold ill-conceived expressed beliefs about the physical world such as that one ball will fall faster than another because it is heavier. At the same time, they also demonstrate accurate recognition of dynamic events. How these representations relate is still unresolved. This study examined 5- to 11-year-olds' (N = 130) predictions and recognition of motion down inclines. Predictions were typically in error, matching previous work, but children largely recognized correct events as correct and rejected incorrect ones. The results also demonstrate while predictions change with increasing age, recognition shows signs of stability. The findings provide further support for a hybrid model of object representations and argue in favour of stable core cognition existing alongside developmental changes. Statement of contribution What is already known on this subject? Children's predictions of physical events show limitations in accuracy Their recognition of such events suggests children may use different knowledge sources in their reasoning What the present study adds? Predictions fluctuate more strongly than recognition, suggesting stable core cognition But recognition also shows some fluctuation, arguing for a hybrid model of knowledge representation. © 2017 The British Psychological Society.

  17. Striving for transparent and credible research: practical guidelines for behavioral ecologists

    Winney, Isabel S.; Krystalli, Anna; Croucher, Michael

    2017-01-01

    Abstract Science is meant to be the systematic and objective study of the world but evidence suggests that scientific practices are sometimes falling short of this expectation. In this invited idea, we argue that any failure to conduct research according to a documented plan (lack of reliability) and/or any failure to ensure that reconducting the same project would provide the same finding (lack of reproducibility), will result in a low probability of independent studies reaching the same outcome (lack of replicability). After outlining the challenges facing behavioral ecology and science more broadly and incorporating advice from international organizations such as the Center for Open Science (COS), we present clear guidelines and tutorials on what we think open practices represent for behavioral ecologists. In addition, we indicate some of the currently most appropriate and freely available tools for adopting these practices. Finally, we suggest that all journals in our field, such as Behavioral Ecology, give additional weight to transparent studies and therefore provide greater incentives to align our scientific practices to our scientific values. Overall, we argue that producing demonstrably credible science is now fully achievable for the benefit of each researcher individually and for our community as a whole. PMID:29622916

  18. Promissory identities: Sociotechnical representations & innovation in regenerative medicine.

    PubMed

    Gardner, John; Higham, Ruchi; Faulkner, Alex; Webster, Andrew

    2017-02-01

    The field of regenerative medicine (RM) is championed as a potential source of curative treatments and economic wealth, and initiatives have been launched in several countries to facilitate innovation within the field. As a way of examining the social dimensions of innovation within regenerative medicine, this paper explores the sociotechnical representations of RM technologies in the UK, and the tensions, affordances and complexities these representations present for actors within the field. Specifically, the paper uses the Science and Technology Studies-inspired notions of 'technology identity' and 'development space' to examine how particular technologies are framed and positioned by actors, and how these positionings subsequently shape innovation pathways. Four developing RM technologies are used as case studies: bioengineered tracheas; autologous chondrocyte implantation; T-cell therapies; and a 'point-of-care' cell preparation device. Using these case studies we argue that there are particular identity aspects that have powerful performative effects and provide momentum to innovation projects, and we argue that there are particular stakeholders in the UK RM landscape who appear to have considerable power in shaping these technology identities and thus innovation pathways.

  19. The dichotomous response of flood and storm extremes to rising global temperatures

    NASA Astrophysics Data System (ADS)

    Sharma, A.; Wasko, C.

    2017-12-01

    Rising temperature have resulted in increases in short-duration rainfall extremes across the world. Additionally it has been shown (doi:10.1038/ngeo2456) that storms will intensify, causing derived flood peaks to rise even more. This leads us to speculate that flood peaks will increase as a result, complying with the storyline presented in past IPCC reports. This talk, however, shows that changes in flood extremes are much more complex. Using global data on extreme flow events, the study conclusively shows that while the very extreme floods may be rising as a result of storm intensification, the more frequent flood events are decreasing in magnitude. The study argues that changes in the magnitude of floods are a function of changes in storm patterns and as well as pre-storm or antecedent conditions. It goes on to show that while changes in storms dominate for the most extreme events and over smaller, more urbanised catchments, changes in pre-storm conditions are the driving factor in modulating flood peaks in large rural catchments. The study concludes by providing recommendations on how future flood design should proceed, arguing that current practices (or using a design storm to estimate floods) are flawed and need changing.

  20. Foucault's notion of problematization: a methodological discussion of the application of Foucault's later work to nursing research.

    2015-09-01

    This study takes its point of departure in an oft-voiced critique that the French philosopher Michel Foucault gives discourse priority over practice, thereby being deterministic and leaving little space for the individual to act as an agent. Based on an interpretation of the latter part of Foucault's oeuvre, we argue against this critique and provide a methodological discussion of the perception that Foucault's method constitutes, primarily, discourse analysis. We argue that it is possible to overcome this critique of Foucault's work by the application of methodological tools adapted from Foucault's later writings and his diagnosis of his own work as studies of forms of problematization. To shed light on the possibilities that this approach offers to the researcher, we present a reading of aspects of Foucault's work, with a focus on his notion of forms of problematization. Furthermore, we elaborate on concepts from his so-called genealogical period, namely 'the dispositive', strategy and tactics. Our interpretation is supported by examples from a study of the emergence of Danish nursing education, which is based on an analytical framework that we developed in the light of an interpretation of aspects of Foucault's work. © 2015 John Wiley & Sons Ltd.

  1. Studying scientific thought experiments in their context: Albert Einstein and electromagnetic induction

    NASA Astrophysics Data System (ADS)

    Potters, Jan; Leuridan, Bert

    2017-05-01

    This article concerns the way in which philosophers study the epistemology of scientific thought experiments. Starting with a general overview of the main contemporary philosophical accounts, we will first argue that two implicit assumptions are present therein: first, that the epistemology of scientific thought experiments is solely concerned with factual knowledge of the world; and second, that philosophers should account for this in terms of the way in which individuals in general contemplate these thought experiments in thought. Our goal is to evaluate these assumptions and their implications using a particular case study: Albert Einstein's magnet-conductor thought experiment. We will argue that an analysis of this thought experiment based on these assumptions - as John Norton (1991) provides - is, in a sense, both misguided (the thought experiment by itself did not lead Einstein to factual knowledge of the world) and too narrow (to understand the thought experiment's epistemology, its historical context should also be taken into account explicitly). Based on this evaluation we propose an alternative philosophical approach to the epistemology of scientific thought experiments which is more encompassing while preserving what is of value in the dominant view.

  2. Internal Gravity Waves in the Magnetized Solar Atmosphere. I. Magnetic Field Effects

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Vigeesh, G.; Steiner, O.; Jackiewicz, J., E-mail: vigeesh@leibniz-kis.de

    Observations of the solar atmosphere show that internal gravity waves are generated by overshooting convection, but are suppressed at locations of magnetic flux, which is thought to be the result of mode conversion into magnetoacoustic waves. Here, we present a study of the acoustic-gravity wave spectrum emerging from a realistic, self-consistent simulation of solar (magneto)convection. A magnetic field free, hydrodynamic simulation and a magnetohydrodynamic (MHD) simulation with an initial, vertical, homogeneous field of 50 G flux density were carried out and compared with each other to highlight the effect of magnetic fields on the internal gravity wave propagation in themore » Sun’s atmosphere. We find that the internal gravity waves are absent or partially reflected back into the lower layers in the presence of magnetic fields and argue that the suppression is due to the coupling of internal gravity waves to slow magnetoacoustic waves still within the high- β region of the upper photosphere. The conversion to Alfvén waves is highly unlikely in our model because there is no strongly inclined magnetic field present. We argue that the suppression of internal waves observed within magnetic flux concentrations may also be due to nonlinear breaking of internal waves due to vortex flows that are ubiquitously present in the upper photosphere and the chromosphere.« less

  3. A re-view of cognitive mediators in learned helplessness.

    PubMed

    Tennen, H

    1982-12-01

    The findings of Oakes and Curtis (1982), Tennen, Drum, Gillen, and Stanton (1982), and Tennen, Gillen, and Drum (1982) provide a challenge to learned helplessness theory's focus on cognitive mediators of the helplessness phenomenon. In response to these findings, Alloy (1982) argues that these studies do not challenge helplessness theory because they do not measure expected control and because they confuse necessary and sufficient causes of learned helplessness. Silver, Wortman, and Klos (1982) contend that these studies provide an inadequate test of the model because subjects are confronted with experiences which are unlike those in their natural environment. The present article argues that by Alloy's (1982) criteria, an adequate test of the learned helplessness model has not yet been conducted. Previous studies which measured expected control have not supported the model's predictions. Moreover, if perceived response-outcome independence is a sufficient, but not a necessary cause of learned helplessness, the model loses much of its heuristic value. In response to the argument that these studies lack ecological validity, this article clarifies the distinction between experimental realism and mundane realism. While real-world studies have discovered intriguing relations between perceptions of control, attributions, and coping with illness or victimization, they have not tested predictions of the learned helplessness model.

    R. Ratcliff and G. McKoon (1995, 1996, 1997; R. Ratcliff, D. Allbritton, & G. McKoon, 1997) have argued that repetition priming effects are solely due to bias. They showed that prior study of the target resulted in a benefit in a later implicit memory task. However, prior study of a stimulus similar to the target resulted in a cost. The present study, using a 2-alternative forced-choice procedure, investigated the effect of prior study in an unbiased condition: Both alternatives were studied prior to their presentation in an implicit memory task. Contrary to a pure bias interpretation of priming, consistent evidence was obtained in 3 implicit memory tasks (word fragment completion, auditory word identification, and picture identification) that performance was better when both alternatives were studied than when neither alternative was studied. These results show that prior study results in enhanced discriminability, not only bias.

  5. The materiality of mathematics: presenting mathematics at the blackboard.

    PubMed

    Greiffenhagen, Christian

    2014-09-01

    Sociology has been accused of neglecting the importance of material things in human life and the material aspects of social practices. Efforts to correct this have recently been made, with a growing concern to demonstrate the materiality of social organization, not least through attention to objects and the body. As a result, there have been a plethora of studies reporting the social construction and effects of a variety of material objects as well as studies that have explored the material dimensions of a diversity of practices. In different ways these studies have questioned the Cartesian dualism of a strict separation of 'mind' and 'body'. However, it could be argued that the idea of the mind as immaterial has not been entirely banished and lingers when it comes to discussing abstract thinking and reasoning. The aim of this article is to extend the material turn to abstract thought, using mathematics as a paradigmatic example. This paper explores how writing mathematics (on paper, blackboards, or even in the air) is indispensable for doing and thinking mathematics. The paper is based on video recordings of lectures in formal logic and investigates how mathematics is presented at the blackboard. The paper discusses the iconic character of blackboards in mathematics and describes in detail a number of inscription practices of presenting mathematics at the blackboard (such as the use of lines and boxes, the designation of particular regions for specific mathematical purposes, as well as creating an 'architecture' visualizing the overall structure of the proof). The paper argues that doing mathematics really is 'thinking with eyes and hands' (Latour 1986). Thinking in mathematics is inextricably interwoven with writing mathematics. © London School of Economics and Political Science 2014.

  19. Symbolic interactionism and the concept of power.

    PubMed

    Dennis, Alex; Martin, Peter J

    2005-06-01

    Symbolic interactionism is often represented as a perspective which is limited by its restriction to 'micro' aspects of social organization. As such, it is allegedly unable to adequately conceptualize 'macro' phenomena such as social structure, patterns of inequality, and power. Such a view is routinely presented in undergraduate textbooks. This paper contests such a view through a consideration of the concept of power. We argue that the interactionist research tradition does show a fundamental concern with power phenomena, and that a reconsideration of the concept is timely in light of theoretical developments in sociology more generally. An increasing concern with the analysis of culture, the continuing influence of Foucault, the development of feminist perspectives, and the emerging consensus around neo-Weberian thought have all contributed to a renewal of interest in themes long ago explored by interactionists. As examples we suggest that interactionist studies in the fields of deviance and education have been concerned above all with the authoritative imposition of consequential identities, i.e., with the social processes through which power is enacted and institutionalized in real situations. Such developments have led some to argue that interactionism has now been incorporated into the mainstream of sociology. We conclude, however, by arguing that such a view runs the risk of granting to orthodox sociological thought a legitimacy which is analytically unwarranted, and which fails to recognize the alternative theoretical and philosophical foundations of symbolic interactionist thought.

  2. Local P violation effects and thermalization in QCD: Views from quantum field theory and holography

    NASA Astrophysics Data System (ADS)

    Zhitnitsky, Ariel R.

    2012-07-01

    We argue that the local violation of P and CP invariance in heavy ion collisions and the universal thermal aspects observed in high energy collisions are in fact two sides of the same coin, and both are related to quantum anomalies of QCD. We argue that the low energy relations representing the quantum anomalies of QCD are saturated by coherent low-dimensional vacuum configurations as observed in Monte Carlo lattice studies. The thermal spectrum and approximate universality of the temperature with no dependence on energy of colliding particles in this framework is due to the fact that the emission results from the distortion of these low-dimensional vacuum sheets rather than from the colliding particles themselves. The emergence of the long-range correlations of P odd domains (a feature which is apparently required for explanation of the asymmetry observed at RHIC and LHC) is also a result of the same distortion of the QCD vacuum configurations. We formulate the corresponding physics using the effective low energy effective Lagrangian. We also formulate the same physics in terms of the dual holographic picture when low-dimensional sheets of topological charge embedded in 4d space, as observed in Monte Carlo simulations, are identified with D2 branes. Finally, we argue that study of these long-range correlations in heavy ion collisions could serve as a perfect test of a proposal that the observed dark energy in present epoch is a result of a tiny deviation of the QCD vacuum energy in expanding universe from its conventional value in Minkowski space-time.

  3. From bioethics to a sociology of bio-knowledge.

    PubMed

    Petersen, Alan

    2013-12-01

    Growing recognition of bioethics' shortcomings, associated in large part with its heavy reliance on abstract principles, or so-called principlism, has led many scholars to propose that the field should be reformed or reconceptualised. Principlism is seen to de-contextualise the process of ethical decision-making, thus restricting bioethics' contributions to debate and policy on new and emergent biotechnologies. This article examines some major critiques of bioethics and argues for an alternative normative approach; namely, a sociology of bio-knowledge focussing on human rights. The article discusses the need for such an approach, including the challenges posed by the recent rise of 'the bio-economy'. It explores some potential alternative bases for a normative sociology of bio-knowledge, before presenting the elements of the proposed human rights-focused approach. This approach, it is argued, will benefit from the insights and concepts offered by various fields of critical scholarship, particularly the emergent sociology of human rights, science and technology studies, Foucaultian scholarship, and feminist bioethics.

  4. Ritual and rational action in hospitals.

    PubMed

    Chapman, G E

    1983-01-01

    Menzies argues that nursing hierarchies and ritual practices protect nurses from the anxieties provoked by encountering human suffering. This proposition is examined with particular reference to ritual practices in nursing. It is argued that Menzies studied nurses in isolation from the societal and subcultural norms and values which direct hospital activity. Her psychodynamic model is contrasted with a sociological model of human conduct and action. The characteristics of ritual and rational action, and the difference between non-rational and irrational rituals, is explored. The findings of three 5-month periods of participant observation are presented as illustrative case material to support the authors view, that ritual procedures are not only defence mechanisms against anxiety, but social acts which generate and convey meaning. Ritual practices described in this analysis include rituals surrounding birth, death, status and power. It is concluded that if nurses wish to change or alter ritual nursing practices in hospital it is necessary to understand their social as well as their psychological meaning.

    2016-08-01

    This paper revisits the debate between Harry Collins and Allan Franklin, concerning the experimenters' regress. Focusing my attention on a case study from recent psychology (regarding experimental evidence for the existence of a Mozart Effect), I argue that Franklin is right to highlight the role of epistemological strategies in scientific practice, but that his account does not sufficiently appreciate Collins's point about the importance of tacit knowledge in experimental practice. In turn, Collins rightly highlights the epistemic uncertainty (and skepticism) surrounding much experimental research. However, I will argue that his analysis of tacit knowledge fails to elucidate the reasons why scientists often are (and should be) skeptical of other researchers' experimental results. I will present an analysis of tacit knowledge in experimental research that not only answers to this desideratum, but also shows how such skepticism can in fact be a vital enabling factor for the dynamic processes of experimental knowledge generation.

    Zepf, Siegfried

    2010-01-01

    The author discusses the problems when psychoanalysis not only neglects socio-critical issues, diversifies its concepts and sets about to define their common ground with the help of brain research findings and/or of infant observation, but also ignores the implications of attempts to legitimate its scientific status by verifying the outcome of its treatments via nomological and/or qualitative study designs. It is argued that if we reduce psychoanalysis to a mere psychotherapeutic measure we displace the factors essential to neurotic disorders into the blind spot of our field of vision, thus rendering psychoanalysis to be a pseudoscience based on appearances alone. Conceptual clarity, it is argued, cannot be gained from the findings of infant observation or those of brain research. Neither can psychoanalytic treatments be investigated in these manners as long as our current understanding of technical concepts remains highly contradictory. In the author's view present-day psychoanalysis gambles Freud's inheritance away and with it, probably, its own future.

  7. Explaining Work Exhaustion From a Coping Theory Perspective: Roles of Techno-Stressors and Technology-Specific Coping Strategies.

    PubMed

    Gaudioso, Fulvio; Turel, Ofir; Galimberti, Carlo

    2015-01-01

    The purpose of this study is to theoretically develop and empirically examine a general coping theory model which explicates the indirect effects of key job-related techno-stressors on job exhaustion. Through this study, we show that techno-stress creators are detrimental to employee well-being and should be treated accordingly. Specifically, we first argue that key techno-stress creators on the job, namely techno-invasion and techno-overload, drive unpleasant states such as work-family conflict and distress. Next, we rely on general coping theory and argue that people respond to these states differently, but with both adaptive and maladaptive technology-specific coping strategies. Adaptive coping behaviors are argued to ultimately reduce work exhaustion, and maladaptive coping strategies are argued to increase it. The proposed model was tested and validated with structural equation modeling techniques applied to self-reported data obtained from a sample of 242 employees of a large organization in the United States. Implications for theory and practice are discussed.

    2010-01-01

    An analysis of Jimi Hendrix's guitar playing and song writing is presented in light of the effects of his mixed-right-handedness on motoric and conceptual processing. It is argued that (i) his mixed-handedness allowed him greater integration of the roles of his left and right hands in guitar playing and (ii) his right-handedness conferred specific benefits in playing a left-handed guitar. In terms of his song writing, the greater interhemispheric interaction (and consequent greater access to right hemisphere processing) associated with mixed-handedness is argued to characterise aspects of his lyrics and vocal delivery.

    In their recent paper [Phys. Rev. A 71, 033622 (2005)], Seaman et al. studied Bloch states of the condensate wave function in a Kronig-Penney potential and calculated the band structure. They argued that the effective mass is always positive when a swallowtail energy loop is present in the band structure. In this Comment, we reexamine their argument by actually calculating the effective mass. It is found that there exists a region where the effective mass is negative even when a swallowtail is present. Based on this fact, we discuss the interpretation of swallowtails in terms of superfluidity.

    Following in a psychological and musicological tradition beginning with Leonard Meyer, and continuing through David Huron, we present a functional, cognitive account of the phenomenon of expectation in music, grounded in computational, probabilistic modeling. We summarize a range of evidence for this approach, from psychology, neuroscience, musicology, linguistics, and creativity studies, and argue that simulating expectation is an important part of understanding a broad range of human faculties, in music and beyond.

  13. Time delay can facilitate coherence in self-driven interacting-particle systems

    NASA Astrophysics Data System (ADS)

    Sun, Yongzheng; Lin, Wei; Erban, Radek

    2014-12-01

    Directional switching in a self-propelled particle model with delayed interactions is investigated. It is shown that the average switching time is an increasing function of time delay. The presented results are applied to studying collective animal behavior. It is argued that self-propelled particle models with time delays can explain the state-dependent diffusion coefficient measured in experiments with locust groups. The theory is further generalized to heterogeneous groups where each individual can respond to its environment with a different time delay.

  14. Great expectations--ethics, avian flu and the value of progress.

    Evans, Nicholas G

    2013-04-01

    A recent controversy over the US National Science Advisory Board for Biosecurity's recommendation to censor two publications on genetically modified H5N1 avian influenza has generated concern over the threat to scientific freedom such censorship presents. In this paper, I argue that in the case of these studies, appeals to scientific freedom are not sufficient to motivate a rejection of censorship. I then use this conclusion to draw broader concerns about the ethics of dual-use research.

    What does "understanding the brain" mean? Here, I review how computational neuroscience, a theoretical approach to the brain, can aid our understanding of the brain. First, I illustrate the study of reinforcement learning and dopamine neurons and argue its success in the light of Marr's three levels of computation. Second, I discuss how Marr's program has led to a computational understanding of the brain, and present computational models of the motor cortex and of a spiking neural network as illustrative examples.

  16. Just do it: flipped lecture, determinants and debate

    NASA Astrophysics Data System (ADS)

    Kensington-Miller, Barbara; Novak, Julia; Evans, Tanya

    2016-08-01

    This paper describes a case study of two pure mathematicians who flipped their lecture to teach matrix determinants in two large mathematics service courses (one at Stage I and the other at Stage II). The purpose of the study was to transform the passive lecture into an active learning opportunity and to introduce valuable mathematical skills, such as debate, argument and disagreement. The students were told in advance to use the online material to prepare, which had a short handout on matrix determinants posted, as the lesson would be interactive and would rely on them having studied this. At the beginning of the lesson, the two mathematicians worked together to model the skill of professional disagreement, one arguing for the cofactor expansion method and the other for the row reduction method. After voting for their preferred method, the students worked in small groups on examples to defend their choice. Each group elected a spokesperson and a political style debate followed as the students argued the pros and cons of each technique. Although one lecture does not establish whether the flipped lecture model is preferable for student instruction, the paper presents a case study for pursuing this approach and for further research on incorporating this style of teaching in Science, Technology, Engineering and Mathematics subjects.

  17. Does framing the hot hand belief change decision-making behavior in volleyball?

    PubMed

    Raab, Markus; MacMahon, Clare

    2015-06-01

    Previous discussions of the hot hand belief, wherein athletes believe that they have a greater chance of scoring after 2 or 3 hits (successes) compared with 2 or 3 misses, have focused on whether this is the case within game statistics. Researchers have argued that the perception of the hot hand in random sequences is a bias of the cognitive system. Yet most have failed to explore the impact of framing on the stability of the belief and the behavior based on it. The authors conducted 2 studies that manipulated the frame of a judgment task. In Study 1, framing was manipulated via instructions in a playmaker allocation paradigm in volleyball. In Study 2, the frame was manipulated by presenting videos for allocation decisions from either the actor or observer perspective. Both manipulations changed the hot hand belief and sequential choices. We found in both studies that the belief in continuation of positive or negative streaks is nonlinear and allocations to the same player after 3 successive hits are reduced. The authors argue that neither the hot hand belief nor hot hand behavior is stable, but rather, both are sensitive to decision frames. The results can inform coaches on the importance of how to provide information to athletes.

    A central challenge facing twenty-first century community-based researchers and prevention scientists is curriculum adaptation processes. While early prevention efforts sought to develop effective programs, taking programs to scale implies that they will be adapted, especially as programs are implemented with populations other than those with whom they were developed or tested. The principle of cultural grounding, which argues that health message adaptation should be informed by knowledge of the target population and by cultural insiders, provides a theoretical rational for cultural regrounding and presents an illustrative case of methods used to reground the keepin’ it REAL substance use prevention curriculum for a rural adolescent population.

  3. Human ecological intervention and the role of forest fires in human ecology.

    PubMed

    Caldararo, N

    2002-06-26

    The present text is a summary of research on the relationship between forest fires and human activities. Numerous theories have been created to explain changes in forests during the late Pleistocene and early Holocene, and a general understanding has developed in the past 50 years regarding natural fire regimes. The present summary is directed to assess the validity of these theories. A re-analysis of the literature argues that the intense forest fires we experience today are an artifact of human intervention in forest ecology, especially by the reduction of herbivores and are relatively recent, approximately 100,000-250,000 BP. The history of fire, especially in the context of the increased dominance of humans, has produced a progressively fire-adapted ecology, which argues for human-free wildlife areas and against prescribed burns under many circumstances.

    2015-09-01

    There is growing interest in using argumentative discourse in educational settings. However, in a previous study, we found that discourse goals (persuasion vs. consensus) while arguing can affect student outcomes in both content learning and reasoning. In this study, we look at argumentative discourse data from a previous study to ask how differences in discourse might account for the differences we observed in learning and reasoning outcomes. One hundred and five dialogues (57 disputative, 48 consensus) between 7th grade science students attending a public high school near Tarragona, Spain. Participants were randomly assigned to conditions and paired with peers who disagreed with them on three topics related to renewable energy sources. After instruction on each topic, they were asked to either 'argue to convince' (persuasion condition) or 'argue to reach consensus' (consensus condition) on that topic. Conversations were audio-recorded and transcribed for analysis. Students in the persuasion condition engaged in shorter conversational exchanges around argumentative claims and were more likely to use moves that foreclosed discussion, whereas students in the consensus condition were more likely to use moves that elicited, elaborated on, and integrated their partners' ideas. When arguing to reach - rather than defend - a conclusion, students are more likely to coconstruct knowledge by exchanging and integrating arguments. These findings are consistent with predictions about the potential of argumentation for knowledge building and suggest that teachers must attend to discourse goals when using argumentation to support learning and reasoning. © 2015 The British Psychological Society.

    Many questions regarding evolution and ontogeny of the insect head remain open. Likewise, the genetic basis of insect head development is poorly understood. Recently, the investigation of gene expression data and the analysis of patterning gene function have revived interest in insect head development. Here, we argue that the red flour beetle Tribolium castaneum is a well suited model organism to spearhead research with respect to the genetic control of insect head development. We review recent molecular data and discuss its bearing on early development and morphogenesis of the head. We present a novel hypothesis on the ontogenetic origin of insect head sutures and review recent insights into the question on the origin of the labrum. Further, we argue that the study of developmental genes may identify the elusive anterior non-segmental region and present some evidence in favor of its existence. With respect to the question of evolution of patterning we show that the head Anlagen of the fruit fly Drosophila melanogaster and Tribolium differ considerably and we review profound differences of their genetic regulation. Finally, we discuss which insect model species might help us to answer the open questions concerning the genetic regulation of head development and its evolution. Copyright © 2010 Elsevier Ltd.

  4. Action Planning Mediates Guidance of Visual Attention from Working Memory.

    PubMed

    Feldmann-Wüstefeld, Tobias; Schubö, Anna

    2015-01-01

    Visual search is impaired when a salient task-irrelevant stimulus is presented together with the target. Recent research has shown that this attentional capture effect is enhanced when the salient stimulus matches working memory (WM) content, arguing in favor of attention guidance from WM. Visual attention was also shown to be closely coupled with action planning. Preparing a movement renders action-relevant perceptual dimensions more salient and thus increases search efficiency for stimuli sharing that dimension. The present study aimed at revealing common underlying mechanisms for selective attention, WM, and action planning. Participants both prepared a specific movement (grasping or pointing) and memorized a color hue. Before the movement was executed towards an object of the memorized color, a visual search task (additional singleton) was performed. Results showed that distraction from target was more pronounced when the additional singleton had a memorized color. This WM-guided attention deployment was more pronounced when participants prepared a grasping movement. We argue that preparing a grasping movement mediates attention guidance from WM content by enhancing representations of memory content that matches the distractor shape (i.e., circles), thus encouraging attentional capture by circle distractors of the memorized color. We conclude that templates for visual search, action planning, and WM compete for resources and thus cause interferences.

    2010-12-01

    We present new Sr-Nd isotope compositions together with major- and trace element concentrations measured for whole rocks and mineral separate phases (apatite, biotite and calcite) from fifteen Cape Verde oceanic carbonatites (Atlantic Ocean). Trace element patterns of calcio- and magnesio-carbonatites present a strong depletion in K, Hf, Zr and Ti and an overall enrichment in Sr and REE relative to Cape Verde basalts, arguing for distinct source components between carbonatites and basalts. Sr and Nd isotopic ratios show small, but significant variations defining a binary mixing between a depleted end-member with unradiogenic Sr and radiogenic Nd values and a ''enriched'' end-member compatible with old marine carbonates. We interpret the depleted end-member as the Cape Verde oceanic lithosphere by comparison with previous studies on Cape Verde basalts. We thus propose that oceanic carbonatites are resulting from the interaction of a deep rooted mantle plume carrying a lower 4He/ 3He signature from the lower mantle and a carbonated metasomatized lithosphere, which by low degree melting produced carbonatite magmas. Sr-Nd compositions and trace element patterns of carbonatites argue in favor of a metasomatic agent originating from partial melting of recycled, carbonated oceanic crust. We have successfully reproduced the main geochemical features of this model using a Monte-Carlo-type simulation.

    1990-01-01

    It is argued that it is essential to have a centrifuge operating during manned space station operations. Background information and a rationale for the research centrifuge are given. It is argued that we must provide a controlled acceleration environment for comparison with microgravity studies. The lack of control groups in previous studies throws into question whether the obseved effects were the result of microgravity or not. The centrifuge could be used to provide a 1-g environment to supply specimens free of launch effects for long-term studies. With the centrifuge, the specimens could be immediately transferred to microgravity without undergoing gradual acclimation. Also, the effects of artificial gravity on humans could be investigated. It is also argued that the presence of the centrifuge on the space station will not cause undo vibrations or other disturbing effects.

    The emotion gratitude is argued to play a pivotal role in building and maintaining social relationships. Evidence is accumulating that links gratitude to increases in relationship satisfaction. Yet, there is currently little evidence for how gratitude does this. The present paper provides experimental evidence of gratitude facilitating relationship-building behaviours. Study 1 provides evidence that gratitude promotes social affiliation, leading one to choose to spend time with a benefactor. Study 2 offers further evidence of gratitude's ability to strengthen relationships by showing that gratitude facilitates socially inclusive behaviours, preferentially towards one's benefactor, even when those actions come at a cost to oneself.

    This article introduces the justification problem for mathematics, which it explores through the case study of 1820s-1840s rationales for the teaching of mathematics to women in the United States. It argues that, while educators in the 1820s justified women's studies through mental discipline (a common reason for men's study), those of the 1830s-1840s increasingly relied on separate, gendered justifications, tied to emerging ideals of middle-class femininity. This article therefore emphasizes the contingency of the justification problem, which serves to break the present-day cycle of gender stereotypes regarding mathematics.

    The present studies demonstrate that conceiving of racial group membership as biologically determined increases acceptance of racial inequities (Studies 1 and 2) and cools interest in interacting with racial outgroup members (Studies 3-5). These effects were generally independent of racial prejudice. It is argued that when race is cast as a biological marker of individuals, people perceive racial outgroup members as unrelated to the self and therefore unworthy of attention and affiliation. Biological conceptions of race therefore provide justification for a racially inequitable status quo and for the continued social marginalization of historically disadvantaged groups.

  15. Vagal activity is quadratically related to prosocial traits, prosocial emotions, and observer perceptions of prosociality.

    2014-12-01

    In the present article, we introduce the quadratic vagal activity-prosociality hypothesis, a theoretical framework for understanding the vagus nerve's involvement in prosociality. We argue that vagus nerve activity supports prosocial behavior by regulating physiological systems that enable emotional expression, empathy for others' mental and emotional states, the regulation of one's own distress, and the experience of positive emotions. However, we contend that extremely high levels of vagal activity can be detrimental to prosociality. We present 3 studies providing support for our model, finding consistent evidence of a quadratic relationship between respiratory sinus arrhythmia--the degree to which the vagus nerve modulates the heart rate--and prosociality. Individual differences in vagal activity were quadratically related to prosocial traits (Study 1), prosocial emotions (Study 2), and outside ratings of prosociality by complete strangers (Study 3). Thus, too much or too little vagal activity appears to be detrimental to prosociality. The present article provides the 1st theoretical and empirical account of the nonlinear relationship between vagal activity and prosociality.

    Wraight, Ralph Denzil

    1997-12-01

    The problem of deciding which stringing materials were used on Italian string keyboard instruments is approached in two ways, by examination of documentary evidence and through the evidence of the instruments. Information on 748 instruments is presented in a catalogue which examines and describes the original condition. 89 new attributions of instruments are presented. From this comprehensive pool of information on the compasses and string lengths of the instruments made it is argued that previous authors worked with too little information to enable accurate conclusions to be drawn. Documentary evidence alone is held to be inconclusive in showing which string material was used for particular instruments at specific periods, and not as useful as argued by some previous authors. The scaling design of instruments is considered and conclusions are advanced that most virginals were designed to be strung with iron wire. It is also argued that most 16th-century harpsichords were intended to be strung with iron wire. A change to brass- scaled designs took place from about 1600-1650, and this also coincided with a loss of popularity of designs employing a 4' stop. The orientation of the first and last notes of Italian compasses on c and f notes is argued to be a consequence of music theory and not a sure indication of pitch level. There were some 16th-century harpsichords made for a pitch a fourth lower than other 8' instruments, but it is argued that there were not two groups a fourth apart in pitch. The string lengths used in the cities of Venice, Florence, Rome, Milan, and Naples are listed and show that a normal 8' range covering a whole tone was in use in all areas at various times. The evidence of the string lengths suggests that instrument makers organised the pitches of instruments into 1/3 tone steps, a scheme which may be related to the apparent use of a 1/3 comma meantone tuning system in an organ of 1494 and clavichord of 1543, before it was described in print by Zarlino in 1571.

  17. Color-word matching stroop task: separating interference and response conflict.

    The Stroop interference task requires a person to respond to a specific dimension of a stimulus while suppressing a competing stimulus dimension. Previous PET and fMRI studies using the Color Stroop paradigm have shown increased activity in the "cognitive division" of the cingulate cortex. In our fMRI study with nine subjects, we used a Color-Word Matching Stroop task. A frontoparietal network, including structures in the lateral prefrontal cortex, the frontopolar region, the intraparietal sulcus, as well as the lateral occipitotemporal gyrus, was activated when contrasting the incongruent vs the neutral condition. However, no substantial activation in either the right or left hemisphere of the anterior cingulate cortex (ACC) was detected. In accordance with a series of recent articles, we argue that the ACC is not specifically involved in interference processes. The ACC seems rather involved in motor preparation processes which were controlled in the present Color-Word Matching Stroop task. We argue that the region around the banks of the inferior frontal sulcus is required to solve interference problems, a concept which can also be seen as a component of task set management.

  18. Training at the Gym, Training for Life: Creating Better Versions of the Self Through Exercise

    2015-01-01

    The present study draws on Scott’s (2011) notion of the Re-Inventive Institution and explores how gym members make sense and give meaning to their exercise regime. Overall, it is argued that for many participants gym exercise is more than physical training; it is also training for life. Based on a thematic analysis of 32 semi-structured interviews it is argued that gym workout is a means to create better versions of the self on mainly three levels. First, gym participants perceive themselves to be efficient and productive in general. Second, gym training is believed to increase the control they have over their lives. Third, gym members associate their gym workout with amplified emotional resilience, believing that fitness workout makes them not only fitter in a physical sense but also fitter and better equipped in a psychological sense. Surprisingly, a small group of regular gym users displayed more critical sentiments and distanced themselves from the images and values the gym stands for. The results of this study can be linked to broader political discourses on health and fitness that make use of corporate managerial vocabularies and are based on ideals of rationalization and efficiency.

  19. Enactivism and neonatal imitation: conceptual and empirical considerations and clarifications

    2014-01-01

    Recently within social cognition it has been argued that understanding others is primarily characterized by dynamic and second person interactive processes, rather than by taking a third person observational stance. Within this enactivist view of intersubjective understanding, researchers differ in their claims regarding the innateness of such processes. Here we proposed to distinguish nativist enactivists—who argue that studies on neonatal imitation support the view that infants already have a non-mentalistic embodied form of intersubjective understanding present at birth—from empiricist enactivists, who claim that those intersubjective processes are learned through social interaction. In this article, we critically examine the empirical studies on neonate imitation and conclude that the available evidence is at least mixed for most types of specific gesture imitations. In the end, only the tongue protrusion imitation appears to be consistent across different studies. If neonates imitate only one single gesture, then a more parsimonious explanation for the tongue protrusion effect could be put forward. Consequently, the nativist enactivist claim that understanding others depends on second person interactive processes already present at birth seems no longer plausible. Although other strands of evidence provide converging evidence for the importance of intersubjective processes in adult social cognition, the available evidence on neonatal imitation calls for a more careful view on the innateness of such processes and suggests that this way of interacting needs to be learned over time. Therefore the available empirical evidence on neonate imitation is in our view compatible with the empiricist enactivist position, but not with the nativist enactivist position. PMID:25228895

    2017-01-01

    Surveys have long been a dominant instrument for data collection in public administration. However, it has become widely accepted in the last decade that the usage of a self-reported instrument to measure both the independent and dependent variables results in common source bias (CSB). In turn, CSB is argued to inflate correlations between variables, resulting in biased findings. Subsequently, a narrow blinkered approach on the usage of surveys as single data source has emerged. In this article, we argue that this approach has resulted in an unbalanced perspective on CSB. We argue that claims on CSB are exaggerated, draw upon selective evidence, and project what should be tentative inferences as certainty over large domains of inquiry. We also discuss the perceptual nature of some variables and measurement validity concerns in using archival data. In conclusion, we present a flowchart that public administration scholars can use to analyze CSB concerns. PMID:29046599

  3. Emotional Life: Exploring Contradictions in Health Behavior Through Creative Writing in Public Health Education.

    PubMed

    Saffran, Lise

    2017-09-01

    Weaving personal experience with literature on social determinants and health humanities, the author argues that including art and literature in public health education will benefit efforts to integrate health care and public health by reminding practitioners that communities are composed of individuals with complicated and often contradictory impulses. She argues that those whose work involves planning interventions and reviewing population data also need to perform the tasks of mental flexibility, of imagination, to think about the people behind the numbers. Together with colleagues at the University of Missouri, the author researches the role of creative writing and imagination in reducing HIV stigma and finds hopeful signs in student responses that they are prepared to consider the contradictions present in human behavior if they are given the opportunity to reflect deeply upon them. Creative writing, literature, and art belong in public health education, she argues, because that is how we make space for emotion in our lives and how we connect with the emotional lives of others.

  4. Culture theorizing past and present: trends and challenges.

    PubMed

    Vandenberg, Helen E R

    2010-10-01

    Over the past several decades, nurses have been increasingly theorizing about the relationships between culture, health, and nursing practice. This culture theorizing has changed over time and has recently been subject to much critical examination. The purpose of this paper is to identify the challenges impeding nurses' ability to build theory about the relationships between culture and health. Through a historical overview, I argue that continued support for the essentialist view of culture can maintain a limited view of complex race relations. I also argue that attempts to apply culture theory, without knowledge of important historical, political, and economic factors, has often resulted in oversimplified versions of what was originally intended. Furthermore, I argue that individual-level interventions alone will be insufficient to address health inequities related to culture. Despite new critical conceptualizations of culture and the uptake of cultural safety, nursing scholars must better address the broader organizational, population, and political interventions needed to address inequities in health. I conclude with suggestions for how nurses might proceed with culture theorizing given these challenges.

    In this paper it is argued that moral distress is an emotional response to an ethical dilemma, and that to date, the literature has largely failed to address the fundamental questions that need to be answered in response to this emotional response. Firstly, does moral distress accurately identify a wrong being done to patients? Secondly, if it does, can nurses carry out this 'wrong doing', but not be responsible for the consequences of their actions? A narrative that reflects the emotional nature of moral distress is presented, with the aim of providing some answers to these questions.

    Although there are many approaches for compiling a planning problem into a static CSP or a scheduling problem, current approaches essentially preserve the structure of the planning problem in the encoding. In this pape: we present a fundamentally different encoding that more accurately resembles a scheduling problem. We sketch the approach and argue, based on an example, that it is possible to automate the generation of such an encoding for problems with certain properties and thus produce a compiler of planning into scheduling problems. Furthermore we argue that many NASA problems exhibit these properties and that such a compiler would provide benefits to both theory and practice.

    Proof-carrying code (PCC) provides a 'gold standard' for establishing formal and objective confidence in program behavior. However, in order to extend the benefits of PCC - and other formal certification techniques - to realistic systems, we must establish the correspondence of a mathematical proof of a program's semantics and its actual behavior. In this paper, we argue that assurance cases are an effective means of establishing such a correspondence. To this end, we present an assurance case pattern for arguing that a proof is free from various proof hazards. We also instantiate this pattern for a proof-based mechanism to provide evidence about a generic medical device software.

    A case of acquired dysgraphia is presented in which the deficit is attributed to an impairment at the level of the Graphemic Output Buffer. It is argued that this patient's performance can be used to identify the representational character of the processing units that are stored in the Orthographic Output Lexicon. In particular, it is argued that the distribution of spelling errors and the types of lexical items which affect error rates indicate that the lexical representations passed from the lexical output system to the Graphemic Output Buffer correspond to the productive morphemes of the language.

    NASA Technical Reports Server (NTRS)

    Caffee, M.; Hohenberg, C. M.; Hudson, B.

    1982-01-01

    The lunar rock considered in the present investigation is a coarse-grained troctolite granulite containing about 58(vol)% plagioclase, 37% olivine, 4% pyroxene, and less than 1% accessory phases with a texture which indicates formation as a cumulate at depths between 10 and 30 km followed by an extended period of slow cooling. A description is presented of noble gas studies of separated minerals from 76535. The quantity of fission xenon from the in situ decay of Pu-244 provides further evidence for different, mineral-specific, isotopic closure times. The presented data shows that 76535 loses its surface-correlated xenon component upon disaggregation. No other xenon component is lost. The presence of solar gases in 76535 would seem to argue in favor of the external acquisition of the parentless extinct isotope effects and consequently favor 'thermal diffusion' and 'adsorption' over local redistribution models.

    2007-01-01

    We review a series of experiments aimed at studying pitch processing in music and speech. These studies were conducted with musician and non musician adults and children. We found that musical expertise improved pitch processing not only in music but also in speech. Demonstrating transfer of training between music and language has interesting applications for second language learning. We also addressed the issue of whether the positive effects of musical expertise are linked with specific predispositions for music or with extensive musical practice. Results of longitudinal studies argue for the later. Finally, we also examined pitch processing in dyslexic children and found that they had difficulties discriminating strong pitch changes that are easily discriminate by normal readers. These results argue for a strong link between basic auditory perception abilities and reading abilities. We used conjointly the behavioral method (Reaction Times and error rates) and the electrophysiological method (recording of the changes in brain electrical activity time-locked to stimulus presentation, Event-Related brain Potentials or ERPs). A set of common processes may be responsible for pitch processing in music and in speech and these processes are shaped by musical practice. These data add evidence in favor of brain plasticity and open interesting perspectives for the remediation of dyslexia using musical training.

    Feldman, O'Connor, and Moscoso del Prado Martín (2009) reported evidence for differential priming of semantically transparent (talker-talk) and semantically opaque (corner-corn) morphological pairs under masked presentation conditions. The present commentary argues that these data should not call into question the theory that morphologically structured words undergo a segmentation process based solely on form, because (1) these results do not contradict existing evidence for morpho-orthographic segmentation, (2) funnel plots suggest that the lack of priming observed for semantically opaque items in this study is inconsistent with findings in the existing literature, and (3) orthographic characteristics of the semantically opaque pairs in this study (rather than semantic factors) are the most likely explanation for these discrepant results.

    The paper discusses the relevance of decision-making models for evaluating the impact of mental disorder on legal responsibility. A three-stage model is presented that analyzes decision making in terms of behavioral control. We argue that understanding dysfunctions in each of the three stages of decision making could provide important insights in the relation between mental disorder and legal responsibility. In particular, it is argued that generating options for action constitutes an important but largely ignored stage of the decision-making process, and that dysfunctions in this early stage might undermine the whole process of making decisions (and thus behavioral control) more strongly than dysfunctions in later stages. Lastly, we show how the presented framework could be relevant to the actual psychiatric assessment of a defendant's decision making within the context of an insanity defense.

    2002-01-01

    This paper presents an outline of the socio-demographic features of the Australian Capital Territory (the ACT) and of its health care system. I describe how health care resources are allocated in the government sector, present a more detailed description of the way that hospital services are purchased, and summarise the government's policy directions for health. I argue that the main directions are sensible, and particularly those that support more integrated care that is largely based in the community. There appear to be no major weaknesses in the budget-share output-based funding model used in the purchase of hospital services, although the rationale for some of the components might be clarified. In total, the ACT government appears to be on the right track. However, I argue that more rapid progress might be possible if there were greater collaboration between the Territory health authority and the relatively powerful private medical profession.

    2004-07-01

    The term 'bioethics' is commonly associated with debates prompted by innovations in medical technology, yet the issues raised by bioethics are not that new. They concern the extent to which medicine and social morality exist in harmony or opposition--issues routinely addressed in the social history of medicine. This paper will argue that historical thinking, understood broadly, has a significant role to play in understanding relations between medicine and social morality, and therefore in contemporary bioethics. It explores past and present uses of metaphor and analogy in shaping perceptions of scientific innovation, and argues for the validity of apparently anachronistic thinking in our judgments of the past. The aims of this paper are ultimately pedagogical: to enable students to look at media reports about developments in medicine and biotechnology in order to problematise what are presented as the self-evident terms of current debate.

  10. What's on the Inside Counts: A Grounded Account of Concept Acquisition and Development

    PubMed Central

    Thill, Serge; Twomey, Katherine E.

    2016-01-01

    Understanding the factors which affect the age of acquisition (AoA) of words and concepts is fundamental to understanding cognitive development more broadly. Traditionally, studies of AoA have taken two approaches, either exploring the effect of linguistic variables such as input frequency (e.g., Naigles and Hoff-Ginsberg, 1998) or the semantics of the underlying concept, such as concreteness or imageability (e.g., Bird et al., 2001). Embodied theories of cognition, meanwhile, assume that concepts, even relatively abstract ones, can be grounded in the embodied experience. While the focus of such discussions has been mainly on grounding in external modalities, more recently some have argued for the importance of interoceptive features, or grounding in complex modalities such as social interaction. In this paper, we argue for the integration and extension of these two strands of research. We demonstrate that the psycholinguistic factors traditionally considered to determine AoA are far from sufficient to account for the variability observed in AoA data. Given this gap, we propose groundability as a new conceptual tool that can measure the degree to which concepts are grounded both in external and, critically, internal modalities. We then present a mechanistic theory of conceptual representation that can account for groundability in addition to the existing variables argued to influence concept acquisition in both the developmental and embodied cognition literatures, and discuss its implications for future work in concept and cognitive development.

  11. The Development of Dalton's Atomic Theory as a Case Study in the History of Science: Reflections for Educators in Chemistry

    Viana, Hélio Elael Bonini; Porto, Paulo Alves

    2010-01-01

    The inclusion of the history of science in science curricula—and specially, in the curricula of science teachers—is a trend that has been followed in several countries. The reasons advanced for the study of the history of science are manifold. This paper presents a case study in the history of chemistry, on the early developments of John Dalton’s atomic theory. Based on the case study, several questions that are worth discussing in educational contexts are pointed out. It is argued that the kind of history of science that was made in the first decades of the twentieth century (encyclopaedic, continuist, essentially anachronistic) is not appropriate for the development of the competences that are expected from the students of sciences in the present. Science teaching for current days will benefit from the approach that may be termed the “new historiography of science”.

    2013-04-01

    This article looks at recent work in cognitive science on mathematical cognition from the perspective of history and philosophy of mathematical practice. The discussion is focused on the work of Lakoff and Núñez, because this is the first comprehensive account of mathematical cognition that also addresses advanced mathematics and its history. Building on a distinction between mathematics as it is presented in textbooks and as it presents itself to the researcher, it is argued that the focus of cognitive analyses of historical developments of mathematics has been primarily on the former, even if they claim to be about the latter.

  13. Equality, explicitness, severity, and rigidity: the Oregon plan evaluated from a Scandinavian perspective.

    PubMed

    Hansson, L F; Norheim, O F; Ruyter, K W

    1994-08-01

    This article is an attempt to evaluate the Oregon plan from the perspective of a Scandinavian national health care system. The Nordic welfare states are marked by a strong emphasis on equality. As an example of an egalitarian system we present the Norwegian health care model in part one. In part two, the arguments in favor of a one tier system in Norway are presented and compared to Oregon's two tier system. Although we argue, in part three, that a comparison of the degree of explicitness in the prioritization process shows that Norway has much to learn from Oregon, we do believe that the Norwegian system has some attractive elements that may function as an important corrective. In part four we present the Norwegian Guidelines for priority-setting and discuss the weight assigned to the severity of disease criterion. It is argued that the exclusion of information about the severity of disease partly explains the counterintuitive ranking of treatment-condition pairs in Oregon's initial method based on the principle of health maximization. A normative analysis of the conflicting norms of efficiency and equality of results is called for. The final part of the paper is devoted to the problem of rigidity. Henry J. Aaron has argued that the Oregon system is insensitive to inter-individual variations within each diagnosis-treatment pair. This objection is a severe one, since the system might end up treating patients unfairly on the individual level. To overcome this problem, we suggest a selection rule that should be more capable of dealing with the problem of rigidity.

  19. Bilingualism and Cognitive Decline: A Story of Pride and Prejudice.

    PubMed

    Woumans, Evy; Versijpt, Jan; Sieben, Anne; Santens, Patrick; Duyck, Wouter

    2017-01-01

    In a recent review, Mukadam, Sommerlad, and Livingston (2017) argue that bilingualism offers no protection against cognitive decline. The authors examined the results of 13 studies (five prospective, eight retrospective) in which monolinguals and bilinguals were compared for cognitive decline and onset of dementia symptoms. Analysis of four of the five prospective studies resulted in the conclusion that there was no difference between monolinguals and bilinguals, whereas seven of the eight retrospective studies actually showed bilingualism to result in a four-to-five year delay of symptom onset. The authors decided to ignore the results from the retrospective studies in favor of those from the prospective studies, reasoning that the former may be confounded by participants' cultural background and education levels. In this commentary, we argue that most of these studies actually controlled for these two variables and still found a positive effect of bilingualism. Furthermore, we argue that the meta-analysis of the prospective studies is not complete, lacking the results of two crucial reports. We conclude that the literature offers substantial evidence for a bilingual effect on the development of cognitive decline and dementia.

  1. What can robots tell us about brains? A synthetic approach towards the study of learning and problem solving.

    PubMed

    Voegtlin, T; Verschure, P F

    1999-01-01

    This paper argues for the development of synthetic approaches towards the study of brain and behavior as a complement to the more traditional empirical mode of research. As an example we present our own work on learning and problem solving which relates to the behavioral paradigms of classical and operant conditioning. We define the concept of learning in the context of behavior and lay out the basic methodological requirements a model needs to satisfy, which includes evaluations using robots. In addition, we define a number of design principles neuronal models should obey to be considered relevant. We present in detail the construction of a neural model of short- and long-term memory which can be applied to an artificial behaving system. The presented model (DAC4) provides a novel self-consistent implementation of these processes, which satisfies our principles. This model will be interpreted towards the present understanding of the neuronal substrate of memory.

  2. Developments in IVF warrant the adoption of new performance indicators for ART clinics, but do not justify the abandonment of patient-centred measures.

    PubMed

    Wilkinson, J; Roberts, S A; Vail, A

    2017-06-01

    Recent advances in embryo freezing technology together with growing concerns over multiple births have shifted the paradigm of appropriate IVF. This has led to the adoption of new performance indicators for ART clinics by national reporting schemes, such as those curated by the Society for Assisted Reproductive Technology (SART) and the Human Fertilization and Embryology Authority (HFEA). Using these organizations as case studies, we review several outcome measures from a statistical perspective. We describe several denominators that are used to calculate live birth rates. These include cumulative birth rates calculated from all fresh and frozen transfer procedures arising from a particular egg collection or cycle initiation, and live birth rates calculated per embryo transferred. Using data from both schemes, we argue that all cycles should be included in the denominator, regardless of whether or not egg collection and fertilization were successful. Excluding cancelled cycles reduces the impact of confounding due to patient characteristics but also removes policy and performance differences which we argue represent relevant sources of variation. It may be misleading to present prospective patients with essentially hypothetical measures of performance predicated on parity of ovarian stimulation and transfer policies. Although live birth per embryo has the advantage of encouraging single embryo transfer, we argue that it is prone to misinterpretation. This is because the likelihood of live birth is not proportional to the number of embryos transferred. We conclude that it is not possible to present a single measure that encompasses both effectiveness and safety. Instead, we propose that a set of clear, relevant outcome indicators is necessary to enable subfertile patients to make informed choices regarding whether and where to be treated. © The Author 2017.

  3. Addiction and autonomy: can addicted people consent to the prescription of their drug of addiction?

    PubMed

    Foddy, Bennett; Savulescu, Julian

    2006-02-01

    It is often claimed that the autonomy of heroin addicts is compromised when they are choosing between taking their drug of addiction and abstaining. This is the basis of claims that they are incompetent to give consent to be prescribed heroin. We reject these claims on a number of empirical and theoretical grounds. First we argue that addicts are likely to be sober, and thus capable of rational thought, when approaching researchers to participate in research. We reject behavioural evidence purported to establish that addicts lack autonomy. We present an argument that extrinsic forces must be irresistible in order to make a choice non-autonomous. We argue that heroin does not present such an irresistible force. We make a case that drug-oriented desires are strong regular appetitive desires, which do not compromise consent. Finally we argue that an addict's apparent desire to engage in a harmful act cannot be construed as evidence of irrational or compulsive thought. On these arguments, a sober heroin addict must be considered competent, autonomous and capable of giving consent. More generally, any argument against legalisation of drugs or supporting infringement of the liberty of those desiring to take drugs of addiction must be based on considerations of harm and paternalism, and not on false claims that addicts lack freedom of the will.

    2006-08-15

    We study the Hawking radiation from Rotating black holes from the gravitational anomalies point of view. First, we show that the scalar field theory near the Kerr black hole horizon can be reduced to the 2-dimensional effective theory. Then, following Robinson and Wilczek, we derive the Hawking flux by requiring the cancellation of gravitational anomalies. We also apply this method to Hawking radiation from higher dimensional Myers-Perry black holes. In the appendix, we present the trace anomaly derivation of Hawking radiation to argue the validity of the boundary condition at the horizon.

    PubMed

    Censabella, Sandrine; Noël, Marie-Pascale

    2008-01-01

    Several authors have argued that mathematical disabilities might result from difficulties in inhibiting irrelevant information. The present study addresses this issue by assessing three inhibition functions in 40 ten-year-old children: suppression of irrelevant information from working memory, inhibition of prepotent responses, and interference control. We found no significant differences between children with math disabilities and typically achieving controls, or between children with arithmetic facts disabilities and children with above-average arithmetic facts skills. These findings, along with other empirical evidence and with theoretical considerations, cast doubt on the inhibition deficit hypothesis.

    In the last few decades, grief and loss research in the psychological domain has focused almost exclusively on its dysfunctional nature. I examine what is underneath these questions about pathology and suggest that our discipline is suffering from an attachment wound where we have dissociated from our historical roots when it comes to the study of grief and loss. I argue that we need to ask new questions about grief and loss and present two examples of my collaborative work to illustrate innovative ways of thinking about and researching grief.

    2013-01-01

    Narcissism research is poorly calibrated across fields of study in part due to confusion over how to integrate normal and pathological descriptions of narcissism. We argue that pathological and normal narcissism can be integrated in a single model that organizes around self-regulation mechanisms. We present theoretical and empirical support for this interpretation, and demonstrate that modeling pathological and normal narcissism as 2 dimensions underlying the narcissistic character can help to resolve some of the inconsistencies in the field regarding how to best assess adaptive and maladaptive expressions of narcissism.

    2010-01-01

    The objective of this comparative study was to evaluate effects of nitrosorbid (NS) and hydrogen sulfide-based balneotherapy (HSB) applied alone or in combination for the treatment of patients presenting with angina of effort. It was shown that long-term HSB therapy enhances the anti-anginal and anti-ischemic action of NS in such patients. The authors argue that prolonged HSB-based maintenance therapy in combination with nitrates prevents habituation to these preparations and potentiates their beneficial therapeutic effect.

  9. Are shame and self-esteem risk factors in prolonged grief after death of a spouse?

    2018-07-01

    Although many single factors of prolonged grief have been identified in the literature, a comprehensive understanding of predictors is still lacking. This article argues that shame and low self-esteem, present risk factors in prolonged grief after spousal loss, based on a review of correlational studies. Using a practitioner-scientist approach, a developmental model of shame as a core factor in prolonged grief is proposed, outlining the progression from childhood relational trauma, to insecure attachment, shame, self-esteem contingent on spousal approval to eventual prolonged grief.

    Regional geochemical patterns are not consistent with the north-south trending microplate boundary that has been proposed by other workers. Correlation coefficients for trace-element data obtained during the current study also argue against sharp compositional breaks in the protolith for the postorogenic granites. Consideration of the data presented here and similar data for granitoids of the eastern Arabian Shield, suggest the existence of a compositionally gradational protolith of continental affinity to the east and oceanic affinity to the west.

    Misdirection refers to the magician’s ability to manipulate people’s attention, thoughts, and memory. It has been argued that some of the techniques used by magicians to orchestrate people’s attention and awareness may provide valuable insights into human cognition. In this paper we review the scientific, as well as some of the magic literature on misdirection. We focus on four main points: (1) the magician’s concept of misdirection, (2) the paradigms used to study misdirection scientifically, (3) review of the current scientific findings, and (4) future directions.

    The present article focuses on connections between part-time special education and the good results of Finnish students in PISA studies. After a brief summary of the comprehensive school system and special education in Finland, PISA results are analysed. The analysis shows that the relative amount of special education targeted at language problems is highest in Finland among those countries from which comparative statistics are available. The writers argue that this preventive language-oriented part-time special education is an important factor behind the good PISA results.

    Mulay, Abby L; Kelly, Elspeth; Cain, Nicole M

    2017-01-01

    In recent years, prisons and jails have become de facto psychiatric hospitals, responsible for the care and treatment of individuals with serious mental illness. Historically, cognitive-behaviorally informed therapeutic approaches have been the treatment of choice among mental health practitioners in correctional settings. However, inmate-clients often present with complex diagnostic issues that are arguably better served by long-term treatment options, such as psychodynamic psychotherapy. We first review the nature of psychotherapy in the correctional setting, as well as treatment barriers and challenges faced by both mental health providers and inmate-clients. We then review treatment studies that examine the efficacy of various therapeutic techniques in correctional/forensic contexts. Finally, we argue that, due to the complex nature of psychopathology, average length of time incarcerated, and treatment issues that arise in this multifaceted and challenging setting, mental health treatment providers should consider providing psychodynamic treatment modalities when working with incarcerated individuals. We also argue that more research is needed to examine the efficacy of these treatment approaches with inmate-clients.

  14. Family Photography and Persecuted Communities: Methodological Challenges.

    PubMed

    McAllister, Kirsten Emiko

    2018-05-01

    This paper examines methodological challenges involved in conducting research on family photographs from persecuted communities, using Japanese Canadian photos as a case study. Approaching family photography as a social practice that instills dominant familial ideologies, the paper examines their "performative scripts" that arrange family members according to normative identities and roles. The paper argues that researchers are not immune to scripts that shape how and what we have been socialized to see (and not see) in family photos. The paper thus presents techniques to distance oneself from these performative scripts and one's involvement in their social and emotional dynamics. Once able to disentangle oneself from the genre's normative practices, the paper argues it is necessary to situate the photos in their social and political context of persecution and survival. Given the insular, inward looking character of family photographs, the paper concludes by calling for intersectional analyses, reflecting on how one might bring one's own family photos into engagement with the photos of Indigenous families and turns to those of the Skwxwú7mesh (Squamish) Nation. © 2018 Canadian Sociological Association/La Société canadienne de sociologie.

  15. Zebrafish antipredatory responses: A future for translational research?

    PubMed Central

    Gerlai, Robert

    2011-01-01

    Human neuropsychiatric conditions associated with abnormally exaggerated or misdirected fear (anxiety disorders and phobias) still represent a large unmet medical need because the biological mechanisms underlying these diseases are not well understood. Animal models have been proposed to facilitate this research. Here I review the literature with a focus on zebrafish, an upcoming laboratory organism in behavioral brain research. I argue that abnormal human fear responses are likely the result of the malfunction of neurobiological mechanisms (brain areas, circuits and/or molecular mechanisms) that originally evolved to support avoidance of predators or other harm in nature. I also argue that the understanding of the normal as well as pathological functioning of such mechanisms may be best achieved if one utilizes naturalistic experimental approaches. In case of laboratory model organisms, this may entail presenting stimuli associated with predators and measuring species-specific antipredatory responses. Although zebrafish is a relatively new subject of such inquiry, I review the recently rapidly increasing number of zebrafish studies in this area, and conclude that zebrafish is a promising research tool for the analysis of the neurobiology and genetics of vertebrate fear responses.

  16. Fundamental Solution For The Self-healing Fracture Pulse

    NASA Astrophysics Data System (ADS)

    Nielsen, S.; Madariaga, R.

    We find the analytical solution for a fundamental fracture mode in the form of a self- similar, self-healing pulse. The existence of such a fracture mode was strongly sug- gested by recent numerical findings but, to our knwledge, no formal proof had been proposed up to date. We present a two dimensional, anti-plane solution for fixed rup- ture and healing velocities, that satisfies both wave equation and stress conditions; we argue that such a solution is plausible even in the absence of rate-weakening in the friction, as an alternative to the classic crack solution. In practice, the impulsive mode rather than the expanding crack mode is selected depending on details of fracture initiation, and is therafter self-maintained. We discuss stress concentration, fracture energy, rupture velocity and compare them to the case of a crack. The analytical study is complemented by various numerical examples and comparisons. On more general grounds, we argue that an infinity of marginally stable fracture modes may exist other than the crack solution or the impulseive fracture described here.

  17. Man in the age of technology.

    PubMed

    Galimberti, Umberto

    2009-02-01

    This paper argues that technology is no longer merely a tool for man's use but has become the environment in which man undergoes modifications. The author traces the role of technology from the Greeks to the present day. For the Greeks, Nature was governed by necessity and therefore unchangeable whereas in the Judeo-Christian tradition, nature was entrusted to man for him to dominate. Modern science studies the world in order to manipulate and dominate nature through the use of technology which has now become an end in itself, governing the solution of political problems and confronting us with problems beyond our competence to resolve. The ethical impact of technology has been to create a change from 'acting' which assumes responsibility for one's actions to 'doing' which is concerned only with the effective execution of a 'job' without concern for the wider consequences. It can no longer be argued that technology is good or bad according to the use we make of it since technology now makes use of us and thus transforms our ethics, social relationships and psychological being.

    2016-12-01

    In a recent letter, Plant (2015) reminded us that proper calibration of our laboratory experiments is important for the progress of psychological science. Therefore, carefully controlled laboratory studies are argued to be preferred over Web-based experimentation, in which timing is usually more imprecise. Here we argue that there are many situations in which the timing of Web-based experimentation is acceptable and that online experimentation provides a very useful and promising complementary toolbox to available lab-based approaches. We discuss examples in which stimulus calibration or calibration against response criteria is necessary and situations in which this is not critical. We also discuss how online labor markets, such as Amazon's Mechanical Turk, allow researchers to acquire data in more diverse populations and to test theories along more psychological dimensions. Recent methodological advances that have produced more accurate browser-based stimulus presentation are also discussed. In our view, online experimentation is one of the most promising avenues to advance replicable psychological science in the near future.

    2005-10-01

    After arguing that most community-based organizations (CBOs) function as complex adaptive systems, this white paper describes the evaluation goals, questions, indicators, and methods most important at different stages of community-based health information outreach. This paper presents the basic characteristics of complex adaptive systems and argues that the typical CBO can be considered this type of system. It then presents evaluation as a tool for helping outreach teams adapt their outreach efforts to the CBO environment and thus maximize success. Finally, it describes the goals, questions, indicators, and methods most important or helpful at each stage of evaluation (community assessment, needs assessment and planning, process evaluation, and outcomes assessment). Literature from complex adaptive systems as applied to health care, business, and evaluation settings is presented. Evaluation models and applications, particularly those based on participatory approaches, are presented as methods for maximizing the effectiveness of evaluation in dynamic CBO environments. If one accepts that CBOs function as complex adaptive systems-characterized by dynamic relationships among many agents, influences, and forces-then effective evaluation at the stages of community assessment, needs assessment and planning, process evaluation, and outcomes assessment is critical to outreach success.

    PubMed

    Avorn, Jerry

    2003-01-01

    The data presented by Joel Weissman and colleagues and by Robert Dubois do not justify the conclusions that the effects of pharmaceutical promotion are beneficial. Among consumers of direct-to-consumer advertising (Weissman and colleagues), those heavily influenced by such promotion were no more likely than others were to have new conditions diagnosed or confirmed and were much less likely to have laboratory studies ordered or lifestyle changes recommended. A second study (Dubois) arguing that drug advertising improves the appropriateness of prescribing relies on unconvincing ecological arguments. A greater presence of noncommercial, public health-oriented communication would make a more useful and cost-effective impact on the nation's health.

  7. The evolution of menstruation: A new model for genetic assimilation

    PubMed Central

    Emera, D.; Romero, R.; Wagner, G.

    2012-01-01

    Why do humans menstruate while most mammals do not? Here, we present our answer to this long-debated question, arguing that (i) menstruation occurs as a mechanistic consequence of hormone-induced differentiation of the endometrium (referred to as spontaneous decidualization, or SD); (ii) SD evolved because of maternal-fetal conflict; and (iii) SD evolved by genetic assimilation of the decidualization reaction, which is induced by the fetus in non-menstruating species. The idea that menstruation occurs as a consequence of SD has been proposed in the past, but here we present a novel hypothesis on how SD evolved. We argue that decidualization became genetically stabilized in menstruating lineages, allowing females to prepare for pregnancy without any signal from the fetus. We present three models for the evolution of SD by genetic assimilation, based on recent advances in our understanding of the mechanisms of endometrial differentiation and implantation. Testing these models will ultimately shed light on the evolutionary significance of menstruation, as well as on the etiology of human reproductive disorders like endometriosis and recurrent pregnancy loss.

    Many pathogens persist in multihost systems, making the identification of infection reservoirs crucial for devising effective interventions. Here, we present a conceptual framework for classifying patterns of incidence and prevalence, and review recent scientific advances that allow us to study and manage reservoirs simultaneously. We argue that interventions can have a crucial role in enriching our mechanistic understanding of how reservoirs function and should be embedded as quasi-experimental studies in adaptive management frameworks. Single approaches to the study of reservoirs are unlikely to generate conclusive insights whereas the formal integration of data and methodologies, involving interventions, pathogen genetics, and contemporary surveillance techniques, promises to open up new opportunities to advance understanding of complex multihost systems.

Single approaches to the study of reservoirs are unlikely to generate conclusive insights whereas the formal integration of data and methodologies, involving interventions, pathogen genetics, and contemporary surveillance techniques, promises to open up new opportunities to advance understanding of complex multihost systems.

  15. Rapidity window dependences of higher order cumulants and diffusion master equation

    2015-10-01

    We study the rapidity window dependences of higher order cumulants of conserved charges observed in relativistic heavy ion collisions. The time evolution and the rapidity window dependence of the non-Gaussian fluctuations are described by the diffusion master equation. Analytic formulas for the time evolution of cumulants in a rapidity window are obtained for arbitrary initial conditions. We discuss that the rapidity window dependences of the non-Gaussian cumulants have characteristic structures reflecting the non-equilibrium property of fluctuations, which can be observed in relativistic heavy ion collisions with the present detectors. It is argued that various information on the thermal and transport properties of the hot medium can be revealed experimentally by the study of the rapidity window dependences, especially by the combined use, of the higher order cumulants. Formulas of higher order cumulants for a probability distribution composed of sub-probabilities, which are useful for various studies of non-Gaussian cumulants, are also presented.

  16. Human reproductive cloning and reasons for deprivation.

    PubMed

    Jensen, D A

    2008-08-01

    Human reproductive cloning provides the possibility of genetically related children for persons for whom present technologies are ineffective. I argue that the desire for genetically related children is not, by itself, a sufficient reason to engage in human reproductive cloning. I show this by arguing that the value underlying the desire for genetically related children implies a tension between the parent and the future child. This tension stems from an instance of a deprivation and violates a general principle of reasons for deprivation. Alternative considerations, such as a right to procreative autonomy, do not appear helpful in making the case for human reproductive cloning merely on the basis of the desire for genetically related children.

    Dawid, Richard

    2018-01-01

    It has been argued in Dawid (String theory and the scientific method, Cambridge University Press, Cambridge, [4]) that physicists at times generate substantial trust in an empirically unconfirmed theory based on observations that lie beyond the theory's intended domain. A crucial role in the reconstruction of this argument of "non-empirical confirmation" is played by limitations to scientific underdetermination. The present paper discusses the question as to how generic the role of limitations to scientific underdetermination really is. It is argued that assessing such limitations is essential for generating trust in any theory's predictions, be it empirically confirmed or not. The emerging view suggests that empirical and non-empirical confirmation are more closely related to each other than one may expect at first glance.

  18. Mediating objects: scientific and public functions of models in nineteenth-century biology.

    2013-01-01

    The aim of this article is to examine the scientific and public functions of two- and three-dimensional models in the context of three episodes from nineteenth-century biology. I argue that these models incorporate both data and theory by presenting theoretical assumptions in the light of concrete data or organizing data through theoretical assumptions. Despite their diverse roles in scientific practice, they all can be characterized as mediators between data and theory. Furthermore, I argue that these different mediating functions often reflect their different audiences that included specialized scientists, students, and the general public. In this sense, models in nineteenth-century biology can be understood as mediators between theory, data, and their diverse audiences.

    While previous studies suggested that regressive forms of onset were not common in autism spectrum disorder (ASD), more recent investigations suggest that the rates are quite high and may be under-reported using certain methods. The current study undertook a systematic investigation of how rates of regression differed by measurement method. Infants with (n = 147) and without a family history of ASD (n = 83) were seen prospectively for up to 7 visits in the first three years of life. Reports of symptom onset were collected using four measures that systematically varied the informant (examiner vs. parent), the decision type (categorical [regression absent or present] vs. dimensional [frequency of social behaviors]), and the timing of the assessment (retrospective vs. prospective). Latent class growth models were used to classify individual trajectories to see whether regressive onset patterns were infrequent or widespread within the ASD group. A majority of the sample was classified as having a regressive onset using either examiner (88%) or parent (69%) prospective dimensional ratings. Rates of regression were much lower using retrospective or categorical measures (from 29 to 47%). Agreement among different measurement methods was low. Declining trajectories of development, consistent with a regressive onset pattern, are common in children with ASD and may be more the rule than the exception. The accuracy of widely used methods of measuring onset is questionable and the present findings argue against their widespread use.

    2017-01-01

    Liquid droplets are very simple objects present in our everyday life. They are extremely important for many natural phenomena as well as for a broad variety of industrial processes. The conventional research areas in which the droplets are studied include physical chemistry, fluid mechanics, chemical engineering, materials science, and micro- and nanotechnology. Typical studies include phenomena such as condensation and droplet formation, evaporation of droplets, or wetting of surfaces. The present article reviews the recent literature that employs droplets as animated soft matter. It is argued that droplets can be considered as liquid robots possessing some characteristics of living systems, and such properties can be applied to unconventional computing through maze solving or operation in logic gates. In particular, the lifelike properties and behavior of liquid robots, namely (i) movement, (ii) self-division, and (iii) group dynamics, will be discussed.

    By analyzing self-reports from sample of 91 college students from the United States who are frequent drivers, the present study examined the prevalence of text messaging (or "texting") while driving and the incidence of recklessness and consequences that accompany this behavior. Analyses revealed that 91% of participants reported having used text messaging while driving, with many reporting doing so with passengers, including children, riding in their vehicles. Further, a substantial number of participants reported driving dangerously above the speed limit and drifting into other traffic lanes while texting, and many reported "sexting" and arguing via text messages while driving. However, these young drivers agreed that texting while driving is dangerous and should be illegal. These results and the limitations to the present study are discussed. Copyright © 2011 Elsevier Ltd.

    2010-03-01

    It is often argued that Western medical responses to illness take illness out of the intimate social contexts within which illness becomes meaningful for people and that, as a result, Western medicine can often constitute an ineffective or, at worst, a disempowering response to illness. While not wishing to challenge such arguments, we seek in this article to present material that might serve as a useful caveat to them. Drawn from interviews conducted as part of an Australian study exploring cross-cultural understandings and experiences of mental illness, we present the accounts of three Vietnamese Australian women. In these accounts, the diagnoses of mental illness that these women had received from their Australian doctors were not presented as being meaningless or disempowering. Rather, as the women presented it, being seen and treated as mentally ill had precipitated and continued to precipitate a sense of belonging and self-worth.

    We argue that the use of high-throughput screening techniques, although expensive and laborious, is justified and necessary in studies that examine biological effects of mobile phone radiation. The "case of hsp27 protein" presented here suggests that even proteins with only modestly altered (by exposure to mobile phone radiation) expression and activity might have an impact on cell physiology. However, this short communication does not attempt to present the full scientific evidence that is far too large to be presented in a single article and that is being prepared for publication in three separate research articles. Examples of the experimental evidence presented here were designed to show the flow of experimental process demonstrating that the use of high-throughput screening techniques might help in rapid identification of the responding proteins. This, in turn, can help in speeding up of the process of determining whether these changes might affect human health.*

  10. Nursing Schadenfreude: the culpability of emotional construction.

    PubMed

    McNamee, Michael John

    2007-09-01

    The purpose of this paper is to examine the concept of Schadenfreude--the pleasure felt at another's misfortune--and to argue that feeling it in the course of health care work, as elsewhere, is evidence of a deficient character. In order to show that Schadenfreude is an objectionable emotion in health care work, I first offer some conceptual remarks about emotions generally and their differential treatment in Kantian and Aristotelian thought. Second, I argue that an appreciation of the rationality of the emotions is crucial to our self-understanding as persons in general and nurses in particular. Third, I present a critique of Portmann's (2000, When Bad Things Happen to Other People. London: Routledge) defence of Schadenfreude with examples from both nursing and medical scenarios. Specifically, I show how his exculpation of the emotion in terms of low self-esteem and a commitment to justice are not compelling. I argue that we are active in the construction of our emotional experiences of Schadenfreude, how we may indeed 'nurse' the emotion, and thus become culpable for them in ethical terms.

  11. In defense of paternalism.

    PubMed

    Loewy, Erich H

    2005-01-01

    This paper argues that we have wrongly and not for the patient's benefit made a form of stark autonomy our highest value which allows physicians to slip out from under their basic duty which has always been to pursue a particular patient's good. In general - I shall argue - it is the patient's right to select his or her own goals and the physician's duty to inform the patient of the feasibility of that goal and of the means needed to attain it. If the goal is not one that is possible, the patient, with the physician and family, must select a feasible goal and then discuss the costs/benefits of various approaches. The physician should take a leading role in helping the patient select the goal. I argue that to simply present a laundry list of means and insist that patients choose for themselves is not only abandoning patients to their autonomy but is, in fact, a crass form of violating the patient's autonomy. Freely choosing not to choose is a choice a patient with decisional capacity is entitled to make and one that needs to be respected.

  12. Interest contagion in violation-of-expectation-based false-belief tasks.

    Falck, Andreas; Brinck, Ingar; Lindgren, Magnus

    2014-01-01

    In the debate about how to interpret Violation-of-Expectation (VoE) based false-belief experiments, it has been suggested that infants are predicting the actions of the agent based on more or less sophisticated cognitive means. We present an alternative, more parsimonious interpretation, exploring the possibility that the infants' reactions are not governed by rational expectation but rather of memory strength due to differences in the allocation of cognitive resources earlier in the experiment. Specifically, it is argued that (1) infants' have a tendency to find more interest in events that observed agents are attending to as opposed to unattended events ("interest contagion"), (2) the object-location configurations that result from such interesting events are remembered more strongly by the infants, and (3) the VoE contrast arises as a consequence of the difference in memory strength between more and less interesting object-location configurations. We discuss two published experiments, one which we argue that our model can explain (Kovács etal., 2010), and one which we argue cannot be readily explained by our model (Onishi and Baillargeon, 2005).

  13. Biodiversity, conservation biology, and rational choice.

    PubMed

    Frank, David

    2014-03-01

    This paper critically discusses two areas of Sahotra Sarkar's recent work in environmental philosophy: biodiversity and conservation biology and roles for decision theory in incorporating values explicitly in the environmental policy process. I argue that Sarkar's emphasis on the practices of conservation biologists, and especially the role of social and cultural values in the choice of biodiversity constituents, restricts his conception of biodiversity to particular practical conservation contexts. I argue that life scientists have many reasons to measure many types of diversity, and that biodiversity metrics could be value-free. I argue that Sarkar's emphasis on the limitations of normative decision theory is in tension with his statement that decision theory can "put science and ethics together." I also challenge his claim that multi-criteria decision tools lacking axiomatic foundations in preference and utility theory are "without a rational basis," by presenting a case of a simple "outranking" multi-criteria decision rule that can violate a basic normative requirement of preferences (transitivity) and ask whether there may nevertheless be contexts in which such a procedure might assist decision makers.

  14. Altruism, egoism, or neither: A cognitive-efficiency-based evolutionary biological perspective on helping behavior.

    Schulz, Armin W

    2016-04-01

    I argue for differences in the cognitive efficiency of different psychologies underlying helping behavior, and present an account of the adaptive pressures that result from these differences. Specifically, I argue that organisms often face pressure to move away from only being egoistically motivated to help: non-egoistic organisms are often able to determine how to help other organisms more quickly and with less recourse to costly cognitive resources like concentration and attention. Furthermore, I also argue that, while these pressures away from pure egoism can lead to the evolution of altruists, they can also lead to the evolution of reciprocation-focused behaviorist helpers or even of reflex-driven helpers (who are neither altruists nor egoists). In this way, I seek to broaden the set of considerations typically taken into account when assessing the evolution of the psychology of helping behavior-which tend to be restricted to matters of reliability-and also try to make clearer the role of evolutionary biological considerations in the discussion of this apparently straightforwardly psychological phenomenon.

  15. On drawing a line through the spectrogram: how do we understand deficits of vocal pitch imitation?

    PubMed Central

    Pfordresher, Peter Q.; Larrouy-Maestri, Pauline

    2015-01-01

    In recent years there has been a remarkable increase in research focusing on deficits of pitch production in singing. A critical concern has been the identification of “poor pitch singers,” which we refer to more generally as individuals having a “vocal pitch imitation deficit.” The present paper includes a critical assessment of the assumption that vocal pitch imitation abilities can be treated as a dichotomy. Though this practice may be useful for data analysis and may be necessary within educational practice, we argue that this approach is complicated by a series of problems. Moreover, we argue that a more informative (and less problematic) approach comes from analyzing vocal pitch imitation abilities on a continuum, referred to as effect magnitude regression, and offer examples concerning how researchers may analyze data using this approach. We also argue that the understanding of this deficit may be better served by focusing on the effects of experimental manipulations on different individuals, rather than attempt to treat values of individual measures, and isolated tasks, as absolute measures of ability.

  16. Medicating the mind: a Kantian analysis of overprescribing psychoactive drugs

    PubMed Central

    Manninen, B A

    2006-01-01

    Psychoactive drugs are being prescribed to millions of Americans at an increasing rate. In many cases these drugs are necessary in order to overcome debilitating emotional problems. Yet in other instances, these drugs are used to supplant, not supplement, interpersonal therapy. The process of overcoming emotional obstacles by introspection and the attainment of self knowledge is gradually being eroded via the gratuitous use of psychoactive medication in order to rapidly attain a release from the common problems that life inevitably presents us with. In this paper, I argue that Kant's formula of humanity, which maintains that persons ought never to treat others or themselves soley as a means to an end, proscribes this. Moreover, Kant argues that we have an imperfect duty of self development, and I argue that we fail to adhere to such a duty whenever we seek to evade the process of introspection and self knowledge in favour of the expedient results that drugs may provide us with as we attempt to overcome the emotional hurdles in our lives.

  9. A Dopamine Hypothesis of Autism Spectrum Disorder.

    PubMed

    Pavăl, Denis

    2017-01-01

    Autism spectrum disorder (ASD) comprises a group of neurodevelopmental disorders characterized by social deficits and stereotyped behaviors. While several theories have emerged, the pathogenesis of ASD remains unknown. Although studies report dopamine signaling abnormalities in autistic patients, a coherent dopamine hypothesis which could link neurobiology to behavior in ASD is currently lacking. In this paper, we present such a hypothesis by proposing that autistic behavior arises from dysfunctions in the midbrain dopaminergic system. We hypothesize that a dysfunction of the mesocorticolimbic circuit leads to social deficits, while a dysfunction of the nigrostriatal circuit leads to stereotyped behaviors. Furthermore, we discuss 2 key predictions of our hypothesis, with emphasis on clinical and therapeutic aspects. First, we argue that dopaminergic dysfunctions in the same circuits should associate with autistic-like behavior in nonautistic subjects. Concerning this, we discuss the case of PANDAS (pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections) which displays behaviors similar to those of ASD, presumed to arise from dopaminergic dysfunctions. Second, we argue that providing dopamine modulators to autistic subjects should lead to a behavioral improvement. Regarding this, we present clinical studies of dopamine antagonists which seem to have improving effects on autistic behavior. Furthermore, we explore the means of testing our hypothesis by using neuroreceptor imaging, which could provide comprehensive evidence for dopamine signaling dysfunctions in autistic subjects. Lastly, we discuss the limitations of our hypothesis. Along these lines, we aim to provide a dopaminergic model of ASD which might lead to a better understanding of the ASD pathogenesis. © 2017 S.

    2014-08-01

    In the present STEM (Science, Technology, Engineering, and Mathematics)-driven society, socioscientific issues (SSI) have become a focus globally and SSI research has grown into an important area of study in science education. Since students attending the social and science programs have a different focus in their studies and research has shown that students attending a science program are less familiar with argumentation practice, we make a comparison of the supporting reasons social science and science majors use in arguing different SSI with the goal to provide important information for pedagogical decisions about curriculum and instruction. As an analytical framework, a model termed SEE-SEP covering three aspects (of knowledge, value, and experiences) and six subject areas (of sociology/culture, economy, environment/ecology, science, ethics/morality, and policy) was adopted to analyze students' justifications. A total of 208 upper secondary students (105 social science majors and 103 science majors) from Sweden were invited to justify and expound their arguments on four SSI including global warming, genetically modified organisms (GMO), nuclear power, and consumer consumption. The results showed that the social science majors generated more justifications than the science majors, the aspect of value was used most in students' argumentation regardless of students' discipline background, and justifications from the subject area of science were most often presented in nuclear power and GMO issues. We conclude by arguing that engaging teachers from different subjects to cooperate when teaching argumentation on SSI could be of great value and provide students from both social science and science programs the best possible conditions in which to develop argumentation skills.

    2004-06-01

    The angry facial expression is an important socially threatening stimulus argued to have evolved to regulate social hierarchies. In the present study, event-related potentials (ERP) were used to investigate the involvement and temporal dynamics of the frontal and parietal regions in the processing of angry facial expressions. Angry, happy and neutral faces were shown to eighteen healthy right-handed volunteers in a passive viewing task. Stimulus-locked ERPs were recorded from the frontal and parietal scalp sites. The P200, N300 and early contingent negativity variation (eCNV) components of the electric brain potentials were investigated. Analyses revealed statistical significant reductions in P200 amplitudes for the angry facial expression on both frontal and parietal electrode sites. Furthermore, apart from being strongly associated with the anterior P200, the N300 showed to be more negative for the angry facial expression in the anterior regions also. Finally, the eCNV was more pronounced over the parietal sites for the angry facial expressions. The present study demonstrated specific electrocortical correlates underlying the processing of angry facial expressions in the anterior and posterior brain sectors. The P200 is argued to indicate valence tagging by a fast and early detection mechanism. The lowered N300 with an anterior distribution for the angry facial expressions indicates more elaborate evaluation of stimulus relevance. The fact that the P200 and the N300 are highly correlated suggests that they reflect different stages of the same anterior evaluation mechanism. The more pronounced posterior eCNV suggests sustained attention to socially threatening information. Copyright 2004 Elsevier B.V.

In primary transmission vibrios pass from the aquatic reservoir to humans via edible aquatic flora or fauna, or drinking water. Secondary transmission consists of faecal-oral transmission from person-to-person and may spawn epidemics. Cholera outbreaks are particularly well documented for the Matlab area of Bangladesh, where a field station has been run since 1963, at which patients from a study population of nearly 200,000 are treated for diarrhoeal diseases and monitored in a longitudinal demographic surveillance system. This paper seeks to illuminate the process of secondary transmission by presenting preliminary results of an analysis of the time-space distribution of cholera cases in Matlab for the period 1970-1982. It is argued that the detection of time-space clusters of cases resulting from secondary transmission requires locational data below the level of the village, that is at the level of the bari, or patrilineally-related household group because this is where inter-personal contact is greatest. The mapping of the study area at the bari level is described briefly and it is argued that the proportion of all asymptomatic infections and cases which can be mapped is great enough to enable inferences about transmission processes to be drawn. Results of the analysis of time-space interaction using the Knox method are presented and provide some support for within-bari clustering of cases resulting from secondary transmission.(ABSTRACT TRUNCATED AT 250 WORDS)

  13. High school students presenting science: An interactional sociolinguistic analysis

    NASA Astrophysics Data System (ADS)

    Bleicher, Robert

    Presenting science is an authentic activity of practicing scientists. Thus, effective communication of science is an important skill to nurture in high school students who are learning science. This study examines strategies employed by high school students as they make science presentations; it assesses students' conceptual understandings of particular science topics through their presentations and investigates gender differences. Data are derived from science presentation given by eight high school students, three females and five males who attended a summer science program. Data sources included videotaped presentations, ethnographic fieldnotes, interviews with presenters and members of the audience, and presenter notes and overheads. Presentations were transcribed and submitted to discourse analysis from an interactional sociolinguistic perspective. This article focuses on the methodology employed and how it helps inform the above research questions. The author argues that use of this methodology leads to findings that inform important social-communicative issues in the learning of science. Practical advice for teaching students to present science, implications for use of presentations to assess conceptual learning, and indications of some possible gender differences are discussed.Received: 14 April 1993; Revised: 15 February 1994;

  14. Gender and Physics: a Theoretical Analysis

    NASA Astrophysics Data System (ADS)

    Rolin, Kristina

    This article argues that the objections raised by Koertge (1998), Gross and Levitt (1994), and Weinberg (1996) against feminist scholarship on gender and physics are unwarranted. The objections are that feminist science studies perpetuate gender stereotypes, are irrelevant to the content of physics, or promote epistemic relativism. In the first part of this article I argue that the concept of gender, as it has been developed in feminist theory, is a key to understanding why the first objection is misguided. Instead of reinforcing gender stereotypes, feminist science studies scholars can formulate empirically testable hypotheses regarding local and contested beliefs about gender. In the second part of this article I argue that a social analysis of scientific knowledge is a key to understanding why the second and the third objections are misguided. The concept of gender is relevant for understanding the social practice of physics, and the social practice of physics can be of epistemic importance. Instead of advancing epistemic relativism, feminist science studies scholars can make important contributions to a subfield of philosophy called social epistemology.

  15. Gene-Environment Interplay in Twin Models

    Hatemi, Peter K.

    In this article, we respond to Shultziner’s critique that argues that identical twins are more alike not because of genetic similarity, but because they select into more similar environments and respond to stimuli in comparable ways, and that these effects bias twin model estimates to such an extent that they are invalid. The essay further argues that the theory and methods that undergird twin models, as well as the empirical studies which rely upon them, are unaware of these potential biases. We correct this and other misunderstandings in the essay and find that gene-environment (GE) interplay is a well-articulated concept in behavior genetics and political science, operationalized as gene-environment correlation and gene-environment interaction. Both are incorporated into interpretations of the classical twin design (CTD) and estimated in numerous empirical studies through extensions of the CTD. We then conduct simulations to quantify the influence of GE interplay on estimates from the CTD. Due to the criticism’s mischaracterization of the CTD and GE interplay, combined with the absence of any empirical evidence to counter what is presented in the extant literature and this article, we conclude that the critique does not enhance our understanding of the processes that drive political traits, genetic or otherwise.

    In a recent interdisciplinary study, Das et al. have attempted to trace the homeland of Ashkenazi Jews and of their historical language, Yiddish (Das et al. 2016. Localizing Ashkenazic Jews to Primeval Villages in the Ancient Iranian Lands of Ashkenaz. Genome Biol Evol. 8:1132–1149). Das et al. applied the geographic population structure (GPS) method to autosomal genotyping data and inferred geographic coordinates of populations supposedly ancestral to Ashkenazi Jews, placing them in Eastern Turkey. They argued that this unexpected genetic result goes against the widely accepted notion of Ashkenazi origin in the Levant, and speculated that Yiddish was originally a Slavic language strongly influenced by Iranian and Turkic languages, and later remodeled completely under Germanic influence. In our view, there are major conceptual problems with both the genetic and linguistic parts of the work. We argue that GPS is a provenancing tool suited to inferring the geographic region where a modern and recently unadmixed genome is most likely to arise, but is hardly suitable for admixed populations and for tracing ancestry up to 1,000 years before present, as its authors have previously claimed. Moreover, all methods of historical linguistics concur that Yiddish is a Germanic language, with no reliable evidence for Slavic, Iranian, or Turkic substrata. PMID:27389685

  17. Sexual and reproductive health and rights and mHealth in policy and practice in South Africa.

    Information and Communications Technology (ICT) offers enormous opportunity and innovation to improve public health and health systems.This paper explores the intersections between mHealth and sexual and reproductive health and rights in both policy and practice. It is a qualitative study, informed by policy review and key informant interviews. Three case studies provide evidence of what is happening on the ground in relation to ICTs and reproductive health and rights. We argue that in terms of policy, there is little overlap between health rights and communication technology. In the area of practice, however, significant interventions address aspects of reproductive health. At present, the extent to which mHealth addresses the full range of reproductive justice and sexual and reproductive health and rights is limited, particularly in terms of government initiatives. The paper argues that mHealth projects tend to avoid contentious aspects of sexual health, while addressing favourable topics such as pregnancy and motherhood. The ways in which information is framed in mHealth mirrors current gaps within sexual and reproductive health and rights, where a limited and conservative lens predominates, and which may result in narrow programming and implementation of services.

  18. Starting over from scratch: social support and youth coping with internal displacement.

    Makhoul, Jihad; Ghanem, Mary; Barbir, Farah

    2011-01-01

    This article presents findings from a qualitative research study with daughters of internally displaced families, more than a decade and half after the end of the Lebanese civil war. In-depth interviews with these adolescent girls indicate that in the absence of universal coverage of social security nets for the Lebanese, the effects of impoverishment and continuous mobility in the suburbs have adverse effects on their sense of stability, schooling, and coping. The article argues that although the effects of impoverishment are not new to similar urban youth populations, the quality of social support networks (ties to rural areas and support from welfare agency services) is a determining factor in the way they cope with adversity. Implications for policy are also presented.

    The methodological quality of primary studies is an important issue when performing meta-analyses or systematic reviews. Nevertheless, there are no clear criteria for how methodological quality should be analyzed. Controversies emerge when considering the various theoretical and empirical definitions, especially in relation to three interrelated problems: the lack of representativeness, utility, and feasibility. In this article, we (a) systematize and summarize the available literature about methodological quality in primary studies; (b) propose a specific, parsimonious, 12-items checklist to empirically define the methodological quality of primary studies based on a content validity study; and (c) present an inter-coder reliability study for the resulting 12-items. This paper provides a precise and rigorous description of the development of this checklist, highlighting the clearly specified criteria for the inclusion of items and a substantial inter-coder agreement in the different items. Rather than simply proposing another checklist, however, it then argues that the list constitutes an assessment tool with respect to the representativeness, utility, and feasibility of the most frequent methodological quality items in the literature, one that provides practitioners and researchers with clear criteria for choosing items that may be adequate to their needs. We propose individual methodological features as indicators of quality, arguing that these need to be taken into account when designing, implementing, or evaluating an intervention program. This enhances methodological quality of intervention programs and fosters the cumulative knowledge based on meta-analyses of these interventions. Future development of the checklist is discussed.

  1. Cognitive penetration of early vision in face perception.

    PubMed

    Cecchi, Ariel S

    2018-06-13

    Cognitive and affective penetration of perception refers to the influence that higher mental states such as beliefs and emotions have on perceptual systems. Psychological and neuroscientific studies appear to show that these states modulate the visual system at the visuomotor, attentional, and late levels of processing. However, empirical evidence showing that similar consequences occur in early stages of visual processing seems to be scarce. In this paper, I argue that psychological evidence does not seem to be either sufficient or necessary to argue in favour of or against the cognitive penetration of perception in either late or early vision. In order to do that we need to have recourse to brain imaging techniques. Thus, I introduce a neuroscientific study and argue that it seems to provide well-grounded evidence for the cognitive penetration of early vision in face perception. I also examine and reject alternative explanations to my conclusion. Copyright © 2018 Elsevier Inc. All rights reserved.

    1981-01-01

    Studies concerning the regulation of the earth atmosphere and the relation of atmospheric changes to the evolution of microbial life are reviewed. The improbable nature of the composition of the earth atmosphere in light of the atmospheric compositions of Mars and Venus and equilibrium considerations is pointed out, and evidence for the existence of microbial (procaryotic) life on earth as far back as 3.5 billion years ago is presented. The emergence of eucaryotic life in the Phanerozoic due to evolving symbioses between different procaryotic species is discussed with examples given of present-day symbiotic relationships between bacteria and eucaryotes. The idea that atmospheric gases are kept in balance mainly by the actions of bacterial cells is then considered, and it is argued that species diversity is necessary for the maintenance and origin of life on earth in its present form.

    We consider the construction of local bulk operators in a black hole background dual to a pure state in conformal field theory. The properties of these operators in a microcanonical ensemble are studied. It has been argued in the literature that typical states in such an ensemble contain firewalls, or otherwise singular horizons. We argue this conclusion can be avoided with a proper definition of the interior operators.

  10. Learning to argue as a biotechnologist: disprivileging opposition to genetically modified food

    2014-03-01

    In the public discussion of genetically modified (GM) food the representations of science as a social good, conducted in the public interest to solve major problems are being subjected to intense scrutiny and questioning. Scientists working in these areas have been seen to struggle for the position of science in society. However few in situ studies of how the debate about science appears in learning situations at the university level have been undertaken. In the present study an introductory course in biotechnology was observed during one semester, lectures and small group supervision concerning GM food were videotaped and student's reports on the issue were collected. The ethnographic approach to Discourse analysis was conducted by means of a set of carefully selected and representative observations of how a group of students learn to argue and appropriate views held in the Discourse they are enculturated into. While socio-scientific issues (SSIs) are often associated with achieving scientific literacy in terms of "informed decisions" involving "rational thought and Discourse" this study shows that SSI in practice, in the context studied here, is primarily concerned with using scientific language to privilege professional understandings of GMOs and discredit public worries and concerns. Scientific claims were privileged over ethical, economical and political claims which were either made irrelevant or rebutted. The students were seen to appropriate a Discourse model held in the biotechnological community that public opposition towards GMO is due to "insufficient knowledge". The present study offers insights into biotechnology students' decision making regarding socio-scientific issues, while also demonstrating the utility of Discourse analysis for understanding learning in this university context. Implications for reflection on the institutional Discourse of science and teaching of controversial issues in science are drawn and the study contributes to the investigation of claims of scientific literacy coupled to SSIs and argumentation

  11. A LATINO ORAL HEALTH PARADOX? USING ETHNOGRAPHY TO SPECIFY THE BIO-CULTURAL FACTORS BEHIND EPIDEMIOLOGICAL MODELS

    PubMed Central

    Horton, Sarah B.; Barker, Judith C.

    2010-01-01

    This article presents evidence of a “Latino oral health paradox,” in which Mexican immigrant parents in California’s Central Valley report having had better oral health status as children in Mexico than their U.S.-born children. Yet little research has explored the specific environmental, social, and cultural factors that mediate the much-discussed “Latino health paradox,” in which foreign-born Latinos paradoxically enjoy better health status than their children, U.S.-born Latinos, and whites. Through ethnography, we explore the dietary and environmental factors that ameliorated immigrant parents’ oral health status in rural Mexico, while ill-preparing them for the more cariogenic diets and environments their children face in the U.S. We argue that studies on the “Latino health paradox” neglect a binational analysis, ignoring the different health status of Latino populations in their sending countries. We use the issue of immigrant children’s high incidence of oral disease to initiate a fuller dialogue between U.S.-based studies of the “health paradox” and non-U.S. based studies of the “epidemiological transition.” We show that both models rely upon a static opposition between “traditional” and “modern” health practices, and argue that a binational analysis of the processes that affect immigrant children’s health can help redress the shortcomings of epidemiological generalizations.

  12. The role of prevention focus under stereotype threat: Initial cognitive mobilization is followed by depletion.

    PubMed

    Ståhl, Tomas; Van Laar, Colette; Ellemers, Naomi

    2012-06-01

    Previous research has demonstrated that stereotype threat induces a prevention focus and impairs central executive functions. The present research examines how these 2 consequences of stereotype threat are related. The authors argue that the prevention focus is responsible for the effects of stereotype threat on executive functions and cognitive performance. However, because the prevention focus is adapted to deal with threatening situations, the authors propose that it also leads to some beneficial responses to stereotype threat. Specifically, because stereotype threat signals a high risk of failure, a prevention focus initiates immediate recruitment of cognitive control resources. The authors further argue that this response initially facilitates cognitive performance but that the additional cognitive demands associated with working under threat lead to cognitive depletion over time. Study 1 demonstrates that stereotype threat (vs. control) facilitates immediate cognitive control capacity during a stereotype-relevant task. Study 2 experimentally demonstrates the process by showing that stereotype threat (vs. control) facilitates cognitive control as a default, as well as when a prevention focus has been experimentally induced, but not when a promotion focus has been induced. Study 3 shows that stereotype threat facilitates initial math performance under a prevention focus, whereas no effect is found under a promotion focus. Consistent with previous research, however, stereotype threat impaired math performance over time under a prevention focus, but not under a promotion focus. 2012 APA, all rights reserved
