Mata and von Helversen's integrative review of adult age differences in search performance makes a good case that cognitive control may impact certain aspects of self-regulation of search. However, information foraging as a framework also offers an avenue to consider how adults of different ages adapt to age-related changes in cognition, such as in cognitive control.

In this study, we used a word search puzzle paradigm to investigate age differences in the rate of information gain and the cues used to make patch-departure decisions in information foraging. The likelihood of patch departure increased as the profitability of the patch decreased generally. Both younger and older adults persisted past the point of optimality as defined by the marginal value theorem, which assumes perfect knowledge of the foraging ecology. Nevertheless, there was evidence that adults were rational in terms (...) of being sensitive to the change in RG for making the patch-departure decisions. However, given the limitations in cognitive resources and knowledge about the ecology, the estimation of RG may not be accurate. Younger adults were more likely to leave the puzzle as the long-term RG incrementally decreased, whereas older adults were more likely to leave the puzzle as the local RG decreased. However, older adults with better executive control were more likely to adjust their likelihood of patch-departure decisions to the long-term change in RG. Thus, age-dependent reliance on the long-term or local change in RG to make patch-departure decisions might be due to individual differences in executive control. (shrink)

The paper develops a new holistic theory of the word by integrating semiotic, linguistic, and psychological perspectives and introduces the Cogitative-Sensory Word Model, the CogSens Model, that unites the human mind and body. Saussure’s two-sided sign is replaced by a Peirce-inspired three-sided conception in which the expression unit mediates two content units, namely, an idea content connected to the human mind and an image content linked to the human body. It is argued that it is the word that makes human (...) language a unique tool of communication. Moreover, it is demonstrated how words interact with grammar to create an utterance. Finally, it is suggested that speech perception, i.e., fission of idea and image content, is the mirror image of speech production, i.e., fusion of idea and image content. (shrink)

In Denmark and Sweden sperm donation is the most debated and contested of the reproductive technologies that are currently in use. Although the two countries are neighbouring welfare states with public healthcare in common, policies and practices of sperm banking and sperm donation differ strongly. Drawing on ethnographic fieldwork, this article explores how the sperm used for donor insemination is narrated, chosen, produced and consumed at sperm banks in Denmark and Sweden.The analysis illustrates that marginalization and stigmatization of infertile men, (...) donors, single women, lesbians and donor children not only takes place in the media and during debates in the Danish and Swedish parliaments where the technology has historically been contested, but also at the sperm banks and fertility clinics. This article therefore calls for more inclusive stories on sperm donation to be narrated. (shrink)

In April 1931, the American Dental Association’s Seal of Acceptance was introduced. The seal is still in use today and has been widely praised in dental literature as a symbol of safety, efficacy and credibility within dental therapeutics and an icon of professionalism for the American Dental Association. The celebratory rhetoric perpetuates a problematic narrative of a unified profession. I argue that it is necessary to go beyond the standard narrative. The complex history of the introduction of the acceptance programme (...) in 1930 and 1931 revolves around personal zeal and struggles for authority between different fractions within the American Dental Association seeking to balance professional ideals with economic necessities. I show how authority and professional identity was claimed, redistributed and communicated within a professional organisation, and demonstrate how the seal was invoked to influence marketing strategies of dental manufacturers, reverse the relationship between manufacturers and the profession of dentistry, to brand dentistry in a wider, public context, and how it became an economic thorn in the side of the Board of Trustees of the American Dental Association.

Autistic individuals without intellectual disabilities are sometimes not diagnosed until adolescence/adulthood. Due to increased risk of co-occurring mental health problems, these individuals may initially be referred to general, mental health services and not always be identified as autistic; some may be misdiagnosed with personality disorder prior to identification of autism. To explore possible mechanisms in misdiagnosis of autism, we report on the case of a young man with severe, non-suicidal self-injury and attention deficit disorder who had been diagnosed with and (...) treated for borderline PD prior to being diagnosed with autism. Following reassessment by mental health clinicians with experience of working with autistic individuals, the patient was diagnosed with autism, ADD, and depression—but not PD. Experiences from this case suggest that presence of co-occurring NSSI, depression, and ADD, as well as lack of comprehensive assessment and lack of autism knowledge in general mental health services, may contribute to risk that autism is misdiagnosed as PD. These findings highlight the need for autism expertise in general mental health services to facilitate appropriate diagnosis for autistic individuals who encounter these services, as well as the importance of undertaking comprehensive assessments.

In its ethics guidelines, the Association of Internet Researchers advocates a bottom-up, case-based approach to research ethics, one that emphasizes that ethical judgement must be based on a sensible examination of the unique object and circumstances of a study, its research questions, the data involved, and the expected analysis and reporting of results, along with the possible ethical dilemmas arising from the case. This article clarifies and illustrates the mind-set and process of such a bottom-up approach to internet research ethics. (...) Two ethics concepts to think with, namely ‘the distance principle’, and the notion of ‘perceived privacy’, are introduced and applied in a concrete empirical internet study, in which web archives based on personal communications on social media formed the main body of data. The empirical case example serves to highlight the unique challenges of internet research ethics, in light of the blurring boundaries between text and person, and between private and public on the internet, with profound implications and challenges for the definition of human subjects, privacy, and so on.

The article provides an instructive in-depth analysis of communicative practices in the personal blog. Its aim is to document the discursive dynamics and interactional ethics of blogging, with a specific focus on negotiations of the blogging self in-between public and private. Based on key findings from an empirical case study of personal blogs, the article addresses the negotiation of the blogging self from three interdependent perspectives: the network structures, patterns of interaction, and thematic orientations of the blog. Instead of approaching (...) the online self as the individual blogger’s self-presentation to an often unknown and unfamiliar audience, I analyse and discuss the ‘blogging self’ as a relational and collaborative accomplishment, as something that is constantly subject to negotiation between author and readers, and is framed by the blog as a communicative genre. The theoretical foundation for this relational approach to the self is inspired by the work of sociologist Georg Simmel on how individuals attune to their networks of affiliation in a process of socialisation (Simmel 1955). The article contributes to the discussion of ethical behaviour and privacy protection in social media by highlighting the role of phatic communication in the blog. Specifically, I demonstrate how participants in the blog network negotiate and maintain an ethos of privacy protection in and through practices associated with the phatic. They do this by adhering to a ‘principle of sociability’, allowing them to experience their communication as personal but not private. (shrink)

We present here the hypothesis that the unique microenvironmental pH landscape of acid‐base transporting epithelia is an important factor in development of epithelial cancers, by rendering the epithelial and stromal cells pre‐adapted to the heterogeneous extracellular pH (pHe) in the tumor microenvironment. Cells residing in organs with net acid‐base transporting epithelia such as the pancreatic ductal and gastric epithelia are exposed to very different, temporally highly variable pHe values apically and basolaterally. This translates into spatially and temporally non‐uniform intracellular pH (...) (pHi) patterns. Disturbed pHe‐ and pHi‐homeostasis contributes to essentially all hallmarks of cancer. Our hypothesis, that the physiological pHe microenvironment in acid‐base secreting epithelia shapes cancers arising in these tissues, can be tested using novel imaging tools. The acidic tumor pHe in turn might be exploited therapeutically. Pancreatic cancers are used as our prime example, but we propose that this concept is also relevant for other cancers of acid‐base transporting epithelia. (shrink)

How do students learn about racism in the absence of ‘race’ as an explanatory concept for current social divisions? This article traces conceptual and affective negotiations of ‘race’ and racism in a Norwegian middle school classroom. Conceptual confusion about ‘race’, racism and lines of inclusion and exclusion in the nation is rife in this educational setting, where the curricular focus is on questions of immigration and integration. Treating ‘race’ as a ‘chameleon-like’ concept that adapts to the cultural context and political (...) situation, the analysis highlights the emotional investments and injuries that discussing race brings forward in the situation through a Kleinian psychoanalytic lens. Working through the affective as well as the conceptual aspects of the classroom’s struggles with ‘race’ and racism, the article argues that racism is enacted in the classroom partly as an effect of the denial of ‘race’ as a current effect of racism. Furthermore, it suggests that the denial of ‘race’ as an explanatory concept veils racial binaries that are enacted through Norwegian ethnonationalism, and facilitates enactment of racist dynamics in education that is intended to prevent racism.

Building upon the scholarship of Michael Polanyi, William Poteat has dedicated himself to offering an alternative model to the Cartesian dichotomy of mind and matter that has dominated Western thought for centuries. These essays, collected by James Nickell and James Stines, cover a wide range of subjects, from Poteat's analysis of the epistemological crisis brought on by the Cartesian program to his first attempts at formulating an alternative to the mind-body dichotomy. These essays relentlessly diagnose the present situation of Western (...) thought by making explicit the philosophical presuppositions to which it is committed. They include theological affirmations, reflections on epistemology, conceptual analyses, as well as dialogues with other writers in the field of cultural criticism and linguistic theory such as George Steiner, Noam Chomsky, and Walker Percy. Most significant is Poteat's bold affirmation of the primacy of persons and his analysis and critique of our cultural misconstructions of human awareness. _The Primacy of Persons and the Language of Culture_ provides an excellent introduction to the scholarship of William Poteat. It should be of particular interest to scholars of philosophy and theology, as well as others who share Poteat's deep concern for the state of human culture. ---------------------------------------------------------------------------------------------------- -------------------------------- The above was already on the database - below was copied from the web William Poteat has dedicated himself to offering an alternative model to the Cartesian dichotomy of mind and matter that has dominated Western thought for centuries.

ABSTRACTThe Norwegian government implemented a comprehensive welfare reform in 2012 to better manage an increasingly care-demanding patient demography while meeting budgetary constraints. This article discusses interdiscursive relationships between policy strategies and language use among rehabilitation professionals. It is based on a synthesis of textual analyses of policy documents and of transcribed interviews to produce complex insights into current rehabilitation discourse. The synthetic product is expressed in the form of two nodal discourses which subsume and articulate in particular ways the constituent (...) discourses of the policies and interviews. One nodal discourse approaches rehabilitation as a clinical practice; the other concerns rehabilitation as a management practice. These discourses serve different purposes. One is based in traditional medical science as a means for political action and relates to the body as an object of government policies and practices. The other relies on the individual... (shrink)

Moral philosophers agree that welfare matters. But they disagree about what it is, or how much it matters. In this vital new work, Wayne Sumner presents an original theory of welfare, investigating its nature and discussing its importance. He considers and rejects all notable theories of welfare, both objective and subjective, including hedonism and theories founded on desire or preference. His own theory connects welfare closely with happiness or life satisfaction. Reacting against the value pluralism that currently dominates moral philosophy, (...) he advances welfare as the only basic ethical value. He concludes by discussing the implications of this thesis for ethical and political theory. Written in clear, non-technical language, and including a definitive survey of other work in this area, Sumner's book is essential reading for moral philosophers, political theorists, and welfare economists.

This book closely examines our commonly held beliefs about human suffering, and offers unique insights into God's role in why we suffer. Dr. Perri critically examines what it means to be human from a Judeo-Christian perspective, and extrapolates from the work of Carl Gustav Jung showing a deeply complex development of human transcendence in human suffering. On an interpersonal level, Dr. Perri elaborates on the work of Martin Buber and Emanuel Levinas and shows how our suffering can be shared and (...) lessened by our unconditionality and presence for the other. Scriptural passages are quoted from both the Hebrew and New Testament texts, and are used to depict the suffering of humankind as seen in the face of Job. It was this face, according to Perri, that Jesus saw in the faces of those He came to redeem, and that ultimately brought Him to the crucifix of redemption. Dr. Perri challenges Sartre's position that our existence precedes our essence, and draws on the work of Abraham Joshua Heschel and Christian theology in this regard. He further elaborates a neurodevelopmental paradigm that creates essence as the basis of our freedom to choose. This book can be read and studied by both professionals in the helping and healing professions, and lay persons seeking to better understand our suffering, and how to better help those who suffer. Dr. Perri offers specific ways in how to be present for those who suffer, how to read and receive the hidden language of human suffering, and how to use silence as a communication skill. (shrink)

Critics of contemporary metaphysics argue that it attempts to do the hard work of science from the ease of the armchair. Physics, not metaphysics, tells us about the fundamental facts of the world, and empirical psychology is best placed to reveal the content of our concepts about the world. Exploring and understanding the world through metaphysical reflection is obsolete. In this paper, I will show why this critique of metaphysics fails, arguing that metaphysical methods used to make claims about the (...) world are similar to scientific methods used to make claims about the world, but that the subjects of metaphysics are not the subjects of science. Those who argue that metaphysics uses a problematic methodology to make claims about subjects better covered by natural science get the situation exactly the wrong way around: metaphysics has a distinctive subject matter, not a distinctive methodology. The questions metaphysicians address are different from those of scientists, but the methods employed to develop and select theories are similar. In the first section of the paper, I will describe the sort of subject matter that metaphysics tends to engage with. In the second section of the paper, I will show how metaphysical theories are classes of models and discuss the roles of experience, common sense and thought experiments in the construction and evaluation of such models. Finally, in the last section I will discuss the way these methodological points help us to understand the metaphysical project. Getting the right account of the metaphysical method allows us to better understand the relationship between science and metaphysics, to explain why doing metaphysics successfully involves having a range of different theories, to understand the role of thought experiments involving fictional worlds, and to situate metaphysical realism in a scientifically realist context.

As is well known among readers of Tradition and Discovery, William H. Poteat was a central influence in bringing Michael Polanyi to the attention of American scholars and, particularly, to the interest of scholarship in religion and theology. Poteat’s own work was heavily impacted by Polanyi. In turn, Polanyi’s affiliationwith Poteat at Duke and elsewhere clearly impressed and edified Polanyi and led to Polanyi’s request for Poteat’s collaboration with him on Meaning and to the prospect of Polanyi’s coming to Duke (...) for six weeks to facilitate this. Unfortunately, that promising time was not realized. This present essay represents an effortto discern a direction in which such a collaboration might have deeply and felicitously influenced Polanyi’s interpretation and celebration of his own poignant, yet quite restless, religious sensibilities.

A central theme to be found in Dewey’s writings is his criticism of theories of knowledge proposed throughout the history of Western philosophy. None of the once familiar “isms,” whether it be a variant of empiricism, rationalism, or idealism, escaped Dewey’s scrutiny. And each in its turn proved to be unacceptable to Dewey, because it was found that each rested upon what Dewey referred to as “the philosophical fallacy,” namely “the conversion of eventual functions into antecedent existence,” or the fallacy (...) of selective emphasis. Basically, this fallacy amounted for Dewey to the emphasis of one aspect of scientific inquiry to the exclusion of the rest, and taking the features characteristic of that aspect as paradigmatic for the purpose of accounting for knowledge. Thus, for example, advocates of what Dewey called sensationalism, for whom knowledge was to be explicated in terms of an immediate acquaintance with a perceptual given, emphasized an aspect of scientific inquiry, viz., that inquiry is engaged in only when some given situation is problematic, without regard to the fact that even those features of a problematic situation, which are taken to be given and stable features for purposes of resolving the problem, are so taken only provisionally, depending upon whether the ensuing inquiry is successful in resolving the problem at hand.
