Theoretical arguments and empirical investigations indicate that a high proportion of published findings do not replicate and are likely false. The current position paper provides a broad perspective on scientific error, which may lead to replication failures. This broad perspective focuses on reform history and on opportunities for future reform. We organize our perspective along four main themes: institutional reform, methodological reform, statistical reform and publishing reform. For each theme, we illustrate potential errors by narrating the story of a fictional (...) researcher during the research cycle. We discuss future opportunities for reform. The resulting agenda provides a resource to usher in an era that is marked by a research culture that is less error-prone and a scientific publication landscape with fewer spurious findings.

Working memory, an important posit in cognitive science, allows one to temporarily store and manipulate information in the service of ongoing tasks. Working memory has been traditionally classified as an explicit memory system – that is, as operating on and maintaining only consciously perceived information. Recently, however, several studies have questioned this assumption, purporting to provide evidence for unconscious working memory. In this paper, we focus on visual working memory and critically examine these studies as well as studies of unconscious (...) perception that seem to provide indirect evidence for unconscious working memory. Our analysis indicates that current evidence does not support an unconscious working memory store, though we offer independent reasons to think that working memory may operate on unconsciously perceived information.

In this paper I shall explain how I came to realize that for as long as I believed that there exists an epistemic gap, or veil of perception, separating the world into that which is subjective and internal to the mind from that which is objective and external to the mind, I was unable to provide a compelling argument for the existence of this same Epistemic Gap ontology.

In recent years, semiotics has become an innovative theoretical framework in mathematics education. The purpose of this article is to show that semiotics can be used to explain learning as a process of experimenting with and communicating about one's own representations of mathematical problems. As a paradigmatic example, we apply a Peircean semiotic framework to answer the question of how students learned the concept of "distribution" in a statistics course by "diagrammatic reasoning" and by developing "hypostatic abstractions," that is by (...) forming new mathematical objects which can be used as means for communication and further reasoning. Peirce's semiotic terminology is used as an alternative for notions such as modeling, symbolizing, and reification. We will show that it is a precise instrument of analysis with regard to the complexity of learning and of communication in mathematics classroom. (shrink)

In this paper I raise concerns that I have with what I perceive to be as a complete lack of warrant for Hume’s assertion that there are only two types of reasoning – demonstrative and probable. (Hume’s fork) What I leave for others to decide is whether this lack of warrant therefore successfully undercuts Hume’s argument for the Problem of Induction.

This is not an academic paper. It is the hurried thinking out loud of an academic who is admittedly late to the game when it comes to taking our present climate catastrophe seriously. What I suggest is that if we want to study living systems, which we must do if we want to increase our chances of survival as a species, we also need to study what I refer to as death systems.

This sentence is almost longer than the romp I go on with science and philosophy in this brief paper.

[For an updated version of this thesis, see Frederik A. Bakker, Epicurean Meteorology: Sources, Method, Scope and Organization, Leiden/Boston: Brill, 2016] This dissertation consists of three studies dealing with various aspects of Epicurean cosmology. The first study discusses the Epicurean practice of explaining astronomical and meteorological phenomena by multiple alternative theories. The second study compares the meteorological accounts of Epicurus and Lucretius with other ancient meteorologies as regards the scope and order of their subject matter. The third one examines (...) the claim that Epicurus and Lucretius held the earth to be flat. (shrink)

In this paper, I share my story about some of my experiences with doubt. Along the way, I also share some philosophical reflections. I know this does not tell you very much, but like I said, I am telling a story, and I do not want to spoil the ending.

This is an open letter addressed to my fellow Pragmatists concerning the Problem of Induction. Others are of course also welcome to read it.

Introduction: Universal health coverage (UHC) was introduced in Iran in 2014. The aim of this study was to evaluate the usage rate of health services by human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients after UHC implementation. Material and methods: In 2018, in a cross-sectional study, we evaluated the outpatients’ needs (within its previous month) and inpatients’ needs (within its previous 6 months) of HIV/AIDS patients in Isfahan province (the center of Iran). Concurrently, we estimated the essential health care services (...) that HIV/AIDS patients have to receive regularly, including vaccination for hepatitis B, measurement of CD4, tuberculosis (TB) assessments and TB treatment, anti-retroviral therapy, examination of viral load, treatment approach, and drug side effects counseling. Two checklists were used for assessing the utilization of health services and essential health cares for HIV/AIDS patients, validated by the Ministry of Health and Medical Education of Iran. Data were analyzed by χ2 test, Pearson’s correlation coefficient, and Spearman’s correlation test. Results: Two hundred and thirteen HIV/AIDS patients completed the questionnaires. The mean age of participants was 41.14 ± 9.23. The outpatient service utilization rate was 31.94% in the previous month and the rate of hospitalization was 126 per 1,000 HIV/AIDS patients in the previous 6 months. The majority of HIV/AIDS patients received essential health services more often than the national standard goals estimation. Conclusions: After UHC implementation, the utilization rate of outpatients and inpatients services in HIV/AIDS patients was more than similar indices in the general population. In addition, HIV/AIDS patients received essential health services adequately. (shrink)

This publication offers the first critical edition of John Buridan’s second set of questions on Aristotle's “De generatione et corruptione”.

De auteurs van Aristoteles in actie menen dat nog iets anders essentieel is voor de vorming van professionals: de notie van praktische wijsheid. Zij ontlenen dit begrip aan de Griekse filosoof Aristoteles (384-322 v.Chr.). Aan de hand van verhalen en casussen uit de onderwijspraktijk laten zij zien hoe praktische wijsheid het fundament vormt onder alle vaardigheden en competenties en hoe je studenten in het middelbaar en hoger beroepsonderwijs praktische wijsheid bijbrengt. -/- Aristoteles in actie is samengesteld door Elke Müller. Het (...) bevat bijdragen van Niek van Antwerpen, Gerben Bakker, Bert van den Bergh, Chris Detweiler, Juul Gooren, Henriëtta Joosten en Elke Müller.
