This paper investigates the notion of semiotic scaffolding in relation to mathematics by considering its influence on mathematical activities, and on the evolution of mathematics as a research field. We will do this by analyzing the role different representational forms play in mathematical cognition, and more broadly on mathematical activities. In the main part of the paper, we will present and analyze three different cases. For the first case, we investigate the semiotic scaffolding involved in pencil and paper multiplication. For (...) the second case, we investigate how the development of new representational forms influenced the development of the theory of exponentiation. For the third case, we analyze the connection between the development of commutative diagrams and the development of both algebraic topology and category theory. Our main conclusions are that semiotic scaffolding indeed plays a role in both mathematical cognition and in the development of mathematics itself, but mathematical cognition cannot itself be reduced to the use of semiotic scaffolding.

This article takes stock of the regularity theory of causation. It considers three challenges to the theory: the problem of joint effects, the problems of redundant causation, and omission‐involving causation. The former is often cited as a special, and especially challenging, problem for regularity theories. But the force of this problem has been greatly overstated. The threat to regularity theories instead comes from the latter two.

Causation is extrinsic. What an event causes depends not just on its own nature and the laws, but on the environment in which it occurs. Had an event occurred under different conditions, it may have had different effects. Yet we often want to say that causation, in at least some respect, is not extrinsic. Events exert an influence on the world themselves, independently of what other events do or do not occur in their surroundings. This paper develops an account of (...) such influence and argues that it provides a solution to the causal exclusion problem. By locating that solution largely within the metaphysics of causation, we can solve the exclusion problem without taking on a commitment to a theory of mind. (shrink)

We present a case study of how mathematicians write for mathematicians. We have conducted interviews with two research mathematicians, the talented PhD student Adam and his experienced supervisor Thomas, about a research paper they wrote together. Over the course of 2 years, Adam and Thomas revised Adam’s very detailed first draft. At the beginning of this collaboration, Adam was very knowledgeable about the subject of the paper and had good presentational skills but, as a new PhD student, did not yet (...) have experience writing research papers for mathematicians. Thus, one main purpose of revising the paper was to make it take into account the intended audience. For this reason, the changes made to the initial draft and the authors’ purpose in making them provide a window for viewing how mathematicians write for mathematicians. We examined how their paper attracts the interest of the reader and prepares their proofs for validation by the reader. Among other findings, we found that their paper prepares the proofs for two types of validation that the reader can easily switch between. (shrink)

This book discusses key philosophical concepts and ideologies, including ontology, epistemology, logic, semantics, moral and political philosophy, theology and aesthetics during classical antiquity. Karsten Friis Johansen charts the history of ancient philosophy from the mythological oral tradition, Homer and early tragedy, to the giants of Plato and Aristotle through to paganism and the genesis of Christianity. A History of Ancient Philosophy also presents detailed analysis of individual ancient philosophers and interpretations and commentary on key philosophical passages.

Across two studies the hypotheses were tested that stressful situations affect both leadership ethical acting and leaders' recognition of ethical dilemmas. In the studies, decision makers recruited from 3 sites of a Swedish multinational civil engineering company provided personal data on stressful situations, made ethical decisions, and answered to stress-outcome questions. Stressful situations were observed to have a greater impact on ethical acting than on the recognition of ethical dilemmas. This was particularly true for situations involving punishment and lack of (...) rewards. The results are important for the Corporate Social Responsibility (CSR) of an organization, especially with regard to the analysis of the Stressors influencing managerial work and its implications for ethical behavior.

Artificial intelligence receives attention in media as well as in academe and business. In media coverage and reporting, AI is predominantly described in contrasted terms, either as the ultimate solution to all human problems or the ultimate threat to all human existence. In academe, the focus of computer scientists is on developing systems that function, whereas philosophy scholars theorize about the implications of this functionality for human life. In the interface between technology and philosophy there is, however, one imperative aspect (...) of AI yet to be articulated: how do intelligent systems make inferences? We use the overarching concept “Artificial Intelligent Behaviour” which would include both cognition/processing and judgment/behaviour. We argue that due to the complexity and opacity of artificial inference, one needs to initiate systematic empirical studies of artificial intelligent behavior similar to what has previously been done to study human cognition, judgment and decision making. This will provide valid knowledge, outside of what current computer science methods can offer, about the judgments and decisions made by intelligent systems. Moreover, outside academe—in the public as well as the private sector—expertise in epistemology, critical thinking and reasoning are crucial to ensure human oversight of the artificial intelligent judgments and decisions that are made, because only competent human insight into AI-inference processes will ensure accountability. Such insights require systematic studies of AI-behaviour founded on the natural sciences and philosophy, as well as the employment of methodologies from the cognitive and behavioral sciences.

No country has yet implemented a pilot to ensure access to or the innovation of new antibiotics for multi-drug infections. A team from national health agencies in Norway, with the support of the Innovative Medicine Initiative-funded project DRIVE-AB, designed a model suitable for the national context, including the selection of the antibiotics, the potential value, and the operational model.

Aristotle’s philosophy of mind is often understood as anticipating present-day functionalist approaches to the mental. In Aristotle on the Sense-Organs Johansen argues at length that such interpretations of what Aristotle has to say about the senses are untenable. First, Aristotle does not allow that the matter of a sense-organ can be identified without reference to the form or function of the organ, so sense-organs are not compositionally plastic. Second, Aristotle’s conception of sense-perception is radically different from anything a philosopher (...) today, functionalist or not, would find credible: acts of sense-perception on Aristotle’s view do not require material changes in the sense-organs. Developed carefully throughout all six chapters, Johansen’s defense of this latter claim is the most significant part of the book, and it will be my focus here. (shrink)

Good academic practice is more than the avoidance of clear-cut cheating. It also involves navigation of the gray zones between cheating and good practice. The existing literature has left students’ understanding of gray zone practices largely unexplored. To begin filling in this gap, we present results from a questionnaire study involving N = 1639 undergraduate students from seven European countries representing all major disciplines. We show that large numbers of these students are unable to identify gray area issues and lack (...) sensitivity to the context dependence of these. We also show that a considerable proportion of students have a poor understanding of concepts like plagiarism and falsification, not only in gray zone scenarios, but also in cases of relatively clear-cut cheating. Our results are similar across the faculties and countries of study, and even for students who have attended academic integrity training. We discuss the implications of this for academic integrity training. (shrink)

Thomas Kjeller Johansen presents a new account of Aristotle's major work on psychology, the De Anima.

In a couple of classical studies, Keeney proposed two sets of variables labelled as value focused thinking (VFT) and alternative-focused thinking (AFT). Value-focused thinking (VFT), he argued, is a creative method that centres on the different decision objectives and how as many alternatives as possible may be generated from them. Alternative-focused thinking (AFT), on the other hand, is a method in which the decision maker takes notice of all the available alternatives and then makes a choice that seems to fit (...) the problem best. The impact of these two methods on idea generation was measured using a sample of employees. The results revealed that employees in the value-focused thinking condition (VFT) produced fewer ideas. Thus, value-focused thinking (VFT) is not only able to facilitate ideation fluency but also to constrain it. Factors such as cognitive effort and motivation may play a part here. However, the quality of the ideas was judged to be higher in terms of creativity and innovativeness. Hence, value-focused thinking (VFT) seems to have a positive impact on the quality of ideas in terms of creativity and innovativeness regardless of ideation fluency. Implications for the design of idea management systems are discussed. (shrink)

Plato's dialogue the Timaeus-Critias presents two connected accounts, that of the story of Atlantis and its defeat by ancient Athens and that of the creation of the cosmos by a divine craftsman. This book offers a unified reading of the dialogue. It tackles a wide range of interpretative and philosophical issues. Topics discussed include the function of the famous Atlantis story, the notion of cosmology as 'myth' and as 'likely', and the role of God in Platonic cosmology. Other areas commented (...) upon are Plato's concepts of 'necessity' and 'teleology', the nature of the 'receptacle', the relationship between the soul and the body, the use of perception in cosmology, and the work's peculiar monologue form. The unifying theme is teleology: Plato's attempt to show the cosmos to be organised for the good. A central lesson which emerges is that the Timaeus is closer to Aristotle's physics than previously thought. (shrink)

Attention-deficit/hyperactivity disorder (ADHD) is currently defined as a cognitive/behavioral developmental disorder where all clinical criteria are behavioral. Inattentiveness, overactivity, and impulsiveness are presently regarded as the main clinical symptoms. The dynamic developmental behavioral theory is based on the hypothesis that altered dopaminergic function plays a pivotal role by failing to modulate nondopaminergic (primarily glutamate and GABA) signal transmission appropriately. A hypofunctioning mesolimbic dopamine branch produces altered reinforcement of behavior and deficient extinction of previously reinforced behavior. This gives rise to delay (...) aversion, development of hyperactivity in novel situations, impulsiveness, deficient sustained attention, increased behavioral variability, and failure to “inhibit” responses (“disinhibition”). A hypofunctioning mesocortical dopamine branch will cause attention response deficiencies (deficient orienting responses, impaired saccadic eye movements, and poorer attention responses toward a target) and poor behavioral planning (poor executive functions). A hypofunctioning nigrostriatal dopamine branch will cause impaired modulation of motor functions and deficient nondeclarative habit learning and memory. These impairments will give rise to apparent developmental delay, clumsiness, neurological “soft signs,” and a “failure to inhibit” responses when quick reactions are required. Hypofunctioning dopamine branches represent the main individual predispositions in the present theory. The theory predicts that behavior and symptoms in ADHD result from the interplay between individual predispositions and the surroundings. The exact ADHD symptoms at a particular time in life will vary and be influenced by factors having positive or negative effects on symptom development. Altered or deficient learning and motor functions will produce special needs for optimal parenting and societal styles. Medication will to some degree normalize the underlying dopamine dysfunction and reduce the special needs of these children. The theory describes how individual predispositions interact with these conditions to produce behavioral, emotional, and cognitive effects that can turn into relatively stable behavioral patterns. Key Words: catecholamine; clumsiness; dopamine; hyperkinesis; hyperkinetic disorder; impulsivity; monoamine; neuromodulator; overactivity; pollutants; reinforcement; reward; verbally governed behavior; soft signs; variability.

This book offers an important study of Aristotle's theory of the sense-organs. It aims to answer two questions central to Aristotle's psychology and biology: why does Aristotle think we have sense-organs, and why does he describe the sense-organs in the way he does? The author looks at all the Aristotelian evidence for the five senses and shows how pervasively Aristotle's accounts of the sense-organs are motivated by his interest in form and function. The book also engages with the celebrated problem (...) of whether perception for Aristotle requires material changes in the perceiver. It argues that, surprisingly to the modern philosopher, nothing in Aristotle's description of the sense-organs requires us to believe in such changes. (shrink)

A case-study, small-group-discussion (“focal problem”) exercise in the history of medicine was designed, piloted, and evaluated in an overseas course and an on-campus elective course for medical students. Results suggest that this is a feasible approach to teaching history of medicine which can overcome some of the problems often encountered in teaching this subject in the medical curriculum.

This study juxtaposes Simone Weil's exposition of God's invitation to know and love the good through the divine signature of beauty stamped on the order of the world and Flannery O'Connor's depiction of a society whose oppressive order allows some characters to oppose outright a divine order or to live under the illusion that the divine invitation is irrelevant because they, in their egoism and materialist values, are the centre of the universe. An examination of O'Connor's and Weil's ideas on (...) order and beauty, grace and decreation, within the disorders of their contexts, reveals both writers' skills in pointing prophetically through disorder to divine order, thus, disclosing bridges of revelation.

The concentration of low‐density lipoprotein (LDL) cholesterol (C) in plasma is a key determinant of cardiovascular disease risk and human genetic studies have long endeavoured to elucidate the pathways that regulate LDL metabolism. Massive genome‐wide association studies (GWASs) of common genetic variation associated with LDL‐C in the population have implicated SORT1 in LDL metabolism. Using experimental paradigms and standards appropriate for understanding the mechanisms by which common variants alter phenotypic expression, three recent publications have presented divergent and even contradictory findings. (...) Interestingly, although these reports each linked SORT1 to LDL metabolism, they did not agree on a mechanism to explain the association. Here, we review recent mechanistic studies of SORT1 – the first gene identified by GWAS as a determinant of plasma LDL‐C to be evaluated mechanistically. (shrink)

This article extends previous research on the impacts of life events on individuals’ religiosity and examines whether individuals’ reactions to life events are affected by childhood relationships with parents. Questionnaires were completed by undergraduate students at a state university in Utah. The results of a multivariate analysis, based on data from undergraduate students raised by two Mormon parents, show that those who had a secure relationship with their mothers were more likely to report the occurrence of positive life events that (...) drew them closer to God. Those who had a secure relationship with their fathers were less likely, than their counterparts, to report the occurrence of either positive or negative life events that took them away from God. In contrast, those with an anxious mother or avoidant father during childhood were more likely to report the occurrence of life events, both positive and negative, that took them away from God.

In 2015, observers argued that the fourth agricultural revolution had been initiated. This article focuses on one part of this high-tech revolution: the origin, development, applications, and user value of unmanned aerial systems (UAS). Institutional changes connected to the UAS innovation are analyzed, based on a Swedish case study. The methods included autoethnography. The theoretical frame was composed by four perspectives: innovation, institutions, sustainability, and ethics. UAS can help farmers cut costs and produce higher quantity with better quality, and also (...) has environmental benefits. However, this promising innovation was exposed to institutional forces and suddenly became subordinated the Act of Camera Surveillance. This study illuminates how legislative institutions can inhibit responsible innovation. The study shows that different ethical perspectives can collide with each other. (shrink)

Purpose – The purpose of this paper is to clarify how IT managers' decision styles affect their evaluation of information technology. Design/methodology/approach – Four different decision styles were assessed in a leadership test directed towards IT managers. Each style included two dimensions: confidence judgment ability and decision heuristic usage. Participants belonging to each style were interviewed and their answers analysed with regard to their reasoning about central areas of IT management. Findings – Results suggest that a decision style combining intuitive (...) and analytical capabilities lead to better evaluations of information technology. Originality/value – The results of the present study are valuable for the understanding of how decision styles impact on IT management in everyday life. (shrink)

Aristotle thinks that an account, alogos, of some sort is characteristic of craft,technē. Some scholars think that thelogoselement oftechnēis tagged onto experience as a theoretical element not directly engaged in successful production: I argue instead that thelogosgrounds the productive ability of craft, and also that is practically orientated in a way that distinguishes it from thelogosof theoretical science. Understanding thelogosof craft thus helps us explain how the craftsman differs both from the merely experienced practitioner and from the theoretical scientist.
