Peter Goldie opens the path to a deeper understanding of our emotional lives through a lucid philosophical exploration of this surprisingly neglected topic. Drawing on philosophy, literature and science, Goldie considers the roles of culture and evolution in the development of our emotional capabilities. He examines the links between emotion, mood, and character, and places the emotions in the context of consciousness, thought, feeling, and imagination. He explains how it is that we are able to make sense of our (...) own and other people's emotions, and how we can explain the very human things which emotions lead us to do. He argues that it is only from the personal point of view that thoughts, reasons, feelings, and actions come into view. This fascinating book gives an accessible but penetrating exploration of an important but mysterious subject. Any reader interested in emotion and its role in understanding our lives will find much to think about here. (shrink)

Models developed using machine learning are increasingly prevalent in scientific research. At the same time, these models are notoriously opaque. Explainable AI aims to mitigate the impact of opacity by rendering opaque models transparent. More than being just the solution to a problem, however, Explainable AI can also play an invaluable role in scientific exploration. This paper describes how post-hoc analytic techniques from Explainable AI can be used to refine target phenomena in medical science, to identify starting points for (...) future investigations of causal relationships, and to generate possible explanations of target phenomena in cognitive science. In this way, this paper describes how Explainable AI—over and above machine learning itself—contributes to the efficiency and scope of data-driven scientific research. (shrink)

Ethics and morality, fundamental concepts in human society, are expected to be upheld by individuals and effectively taught by teachers to new generations. This study delves into the perceptions of preservice teachers regarding ethics and good within the framework of an ethics and morality course in education. It also explores the ethical and unethical behaviors these teachers most commonly encounter in their school experiences. Utilizing a qualitative case study methodology, the research provides an in-depth analysis of ethics, the concept of (...) good, ethical and unethical behaviors within the Turkish context. Through thematic analysis of data collected over various weeks, the findings reveal that participants perceive ethics as actions, individuals, and ideas that embody values such as justice, respect, and honesty. Their decision-making is influenced by diverse ethical filters aligned with normative ethical theories. For instance, an act is deemed ethical if it does not limit freedom and harm others, conforms to societal norms, benefits others, adheres to laws and rules, instills a sense of righteousness, and stems from good intentions. Furthermore, the study identifies six key qualities defining the concept of good: evoking happiness, being beneficial, proper, pure, preferred, and encompassing both moral and ethical dimensions. The experiences of ethical and unethical acts among participants predominantly relate to themes of inequality versus justice, harshness versus love, ineffective versus effective teaching, inconsistency versus role model behaviors, undesired versus desired relationships with school stakeholders, and the breach versus balance between professional and private life. Overall, this research highlights significant aspects of how preservice teachers perceive the concepts of ethics and good along with unethical behaviors, offering valuable insights for teacher education.

Conceptual engineering involves revising our concepts. It can be pursued as a specific philosophical methodology, but is also common in ordinary, non-philosophical, contexts. How does our capacity for conceptual engineering fit into human cognitive life more broadly? I hold that conceptual engineering is best understood alongside practices of conceptual exploration, examples of which include conceptual supposition (i.e. suppositional reasoning about alternative concepts), and conceptual comparison (i.e. comparisons between possible concept choices). Whereas in conceptual engineering we aim to change the (...) concepts we use, in conceptual exploration, we reason about conceptual possibilities. I approach conceptual exploration via the linguistic tools we use to communicate about concepts, using metalinguistic negotiation, convention-shifting conditionals, and metalinguistic comparatives as my key examples. I present a linguistic framework incorporating conventions that can account for this communication in a unified way. Furthermore, I argue that conceptual exploration helps undermine skepticism about conceptual engineering itself. (shrink)

Studies have documented that career exploration is significantly associated with CDSE, but how this association occurred is not clear yet. This study committed to clarifying the mechanism underlying the relationship between career exploration and CDSE by investigating the mediation effect of work volition and career adaptability among 586 pre-service kindergarten teachers. The participants are recruited from Ningxia Hui Autonomous Region in northwest China, covering Han, Hui, and other minorities. They took part in a two-wave longitudinal survey and reported (...) on their career exploration at T1, work volition, career adaptability, and career decision self-efficacy at T2. Results showed that T1 career exploration is directly related to the T2 CDSE. Further, career exploration contributed to the CDSE through both the separated mediation path and the chained mediation path of T2 work volition and T2 career adaptability. The results suggest that individuals who engage in more career exploration activities are likely to have more confidence in their abilities to make career decisions over time, which was partially and serially explained by individuals’ perception of capacity despite constraints and greater self-regulatory strength. This study is a first attempt to deeply clarify the link between career exploration and CDSE, and the findings shed light on the independent and serial mediating effects of work volition and career adaptability. The implications and limitations are discussed. (shrink)

Since the time of Hippocrates, madness has typically been viewed through the lens of disease, dysfunction, and defect. In 'Madness', philosopher of science Justin Garson presents a radically different paradigm for conceiving of madness and the forms that it takes. In this paradigm, which he calls madness-as-strategy, madness is neither a disease nor a defect, but a designed feature, like the heart or lungs.

International large-scale assessments, such as PISA, provide structured and static data. However, due to its extensive databases, several researchers place it as a reference in Big Data in Education. With the goal of exploring which factors at country, school and student level have a higher relevance in predicting student performance, this paper proposes an Educational Data Mining approach to detect and analyze factors linked to academic performance. To this end, we conducted a secondary data analysis and built decision trees (C4.5 (...) algorithm) to obtain a predictive model of school performance. Specifically, we selected as predictor variables a set of socioeconomic, process and outcome variables from PISA 2018 and other sources (World Bank, 2020). Since the unit of analysis were schools from all the countries included in PISA 2018 (n= 21,903), student and teacher predictor variables were imputed to the school database. Based on the available student performance scores in Reading, Math, and Science, we applied k-means clustering to obtain a categorized (three categories) target variable of global school performance. Results show the existence of two main branches in the decision tree, split according to the schools’ mean socioeconomic status (SES). While performance in high-SES schools is influenced by educational factors such as metacognitive strategies or achievement motivation, performance in low-SES schools is affected in greater measure by country-level socioeconomic indicators such as GDP, and individual educational indicators are relegated to a secondary level. Since these evidences are in line and delve into previous research, this work concludes by analyzing its potential contribution to support the decision making processes regarding educational policies.

Live streaming is a unique form of media that creates a direct line of interaction between streamers and viewers. While previous research has explored the social motivations of those who stream and watch streams in the gaming community, there is a lack of research that investigates intimate self-disclosure in this context, such as discussing sensitive topics like mental health on platforms such as Twitch.tv. This study aims to explore discussions about mental health in gaming live streams to better understand how (...) people perceive discussions of mental health in this new media context. The context of live streaming is particularly interesting as it facilitates social interactions that are masspersonal in nature: the streamer broadcasts to a larger, mostly unknown audience, but can also interact in a personal way with viewers. In this study, we interviewed Twitch viewers about the streamers they view, how and to what extent they discuss mental health on their channels in relation to gaming, how other viewers reacted to these discussions, and what they think about live streams, gaming-focused or otherwise, as a medium for mental health discussions. Through these interviews, our team was able to establish a baseline of user perception of mental health in gaming communities on Twitch that extends our understanding of how social media and live streaming can be used for mental health conversations. Our first research question unraveled that mental health discussions happen in a variety of ways on Twitch, including during gaming streams, Just Chatting talks, and through the stream chat. Our second research question showed that streamers handle mental health conversations on their channels in a variety of ways. These depend on how they have built their channel, which subsequently impacts how viewers perceive mental health. Lastly, we learned that viewers’ reactions to mental health discussions depend on their motivations for watching the stream such as learning about the game, being entertained, and more. We found that more discussions about mental health on Twitch led to some viewers being more cautious when talking about mental health to show understanding. (shrink)

"'Buddhist Ethics' presents an outline of Buddhist ethical thought. It is not a defense of Buddhist approaches to ethics as opposed to any other, nor is it a critique of the Western tradition. Garfield presents a broad overview of a range of Buddhist approaches to the question of moral philosophy. He argues that while there are important points of contact with these Western frameworks, Buddhist ethics is distinctive, and is a kind of moral phenomenology that is concerned with the ways (...) in which we experience ourselves as agents and others as moral fellows"--.

The purpose of this article is to examine whether patient/client autonomy is always compatible with the nurse’s role of advocacy. The author looks separately at the concepts of autonomy and advocacy, and considers them in relation to the reality of clinical practice from professional, ethical and legal perspectives. Considerable ambiguity is found regarding the legitimacy of claims of a unique function for nurses to act as patient advocates. To act as an advocate may put nurses at personal and professional risk. (...) It may also be deemed arrogant and insulting to other health care professionals. Patient autonomy can be seen as a subcategory of the right of every individual to self-determination, and as such is protected by law. However, it is questionable whether the traditionally paternalistic approach to health care provision truly respects the autonomous rights of each patient. The author considers examples and cases from the literature that resulted in professional and/or personal difficulties for the nurses involved, and also reflects on an incident from her own practice where a positive outcome was achieved that demonstrated compatibility between the concepts under consideration.

This essay attempts to give definitions and identity conditions for the two predominant senses of ‘Argument’ currently in use, the one involving reasons for a conclusion and the other denoting an expressed disagreement with ensuing verbal behaviour by two parties. I see Johnson's new concept of ‘Argument’, as developed in his book Manifest Rationality, as a hybrid of the two common senses of ‘Argument’, and, accordingly, I try to define and give the identity conditions of Johnson-arguments. Finally, I disagree with (...) Johnson on the nature of the definition he thinks he has proposed, and I conclude with observations suggesting that his logical perspective has dialectical and rhetorical components. (shrink)

The most distinctive feature of Murdoch's philosophical project is her attempt to reclaim the exploration of moral life as a legitimate topic of philosophical investigation. In contrast to the predominant focus on action and decision, she argues that “what we require is a renewed sense of the difficulty and complexity of the moral life and the opacity of persons. We need more concepts in terms of which to picture the substance of our being” (AD 293).1 I shall argue that (...) to fully appreciate the novelty of this proposal we need to recognize some elements of continuity with analytic methods of philosophical inquiry and themes that belong to continental traditions. On Murdoch's view, the most important question facing moral philosophy is that of whether and how we can become better. In order to describe moral progress and failure, struggle and ascent, we need ethical concepts capable of capturing mental events such as change in mind, self-examination, and redescription. These concepts are presently unavailable, and this lack seriously undermines our attempts to understand the phenomena of morality. Because of this conceptual loss, we succumb to the mistaken idea that moral life coincides with its scattered outer manifestations, i.e. public acts. Instead, Murdoch urges us “the moral life […] is something that goes on continually, not something that is switched off in between the occurrence of explicit moral choices” (SG 37).2 Murdoch's point is that we need to conceive the locus of agency more broadly if we want to understand the complicated machinery of action. But perhaps more importantly, she points out that we may be morally active while entertaining a contemplative attitude, which does not issue in action. The grain of moral life, she argues, is constituted by the.. (shrink)

Abstract:I examine the often-denigrated concept of the novel of ideas from its inception and critical decline to its relatively recent revival. Using a variant of the exploitation-exploration dilemma in psychology, I suggest that early usage referred to works that exploit philosophical principles—or better, enact them—by setting philosophical positions in conflict. By contrast, use of the concept for more recent works sees characters and plots exploring philosophical stances. The shift corresponds with the greater attention paid to complexity and ambiguity that (...) are hallmarks of continental philosophy and neopragmatism, and with it greater need to explore philosophical stances through fiction.

The purpose of this paper is to use neuroscientific evidence to address the philosophical issue of intertheoretic reduction. In particular, we present a literature review and a new experiment to show that the reduction of cognitive psychology to neuroscience is implausible. To make this case, we look at research using object exploration, an important experimental paradigm in neuroscience, behavioral genetics and psychopharmacology. We show that a good deal of object exploration research is potentially confounded precisely because it assumes (...) that psychological generalizations can be reduced to neuroscientific ones.

Amateurs are neither regular consumers nor professionals. What makes them distinctive? To answer that question, this ethnographic study focuses on wine amateurs who show a distinctive feature compared to regular consumers: for them, wine is not a straightforward reality but a world to explore. Wine exploration drives an evolution that transforms both wine and amateurs’ disposition towards it. Amateurs usually start with the discovery of the wines and their tastes, which may turn into an ability to attune to and (...) finally produce taste and good quality. Amateurs’ passion, initially fuelled by the discovery of unknown tastes, is then informed by the renewal of the taste experience itself. Following amateurs in their exploratory activity allows us to extend the analysis beyond scholars’ usual focus on one of its particularly normative stages, and to propose a renewed account of the amateur that is quite remote from the standard image of the ‘cultural prescriber’.

Past research has suggested that those spontaneous movements of the human hand made during talk convey significant semantic information over and above the speech, at least when the unit of speech analyzed is the individual clause. However, no previous research has tested whether this information is represented linguistically elsewhere in the narrative . The first study, reported here, uses an experimental procedure to identify which specific imagistic gestures add semantic information to the speech. The second study analyzes whether the specific (...) gestures still do this when respondents hear the whole narrative. It was found that two thirds of the semantic information, thought to be carried by the gestures, is, in fact, represented in the linguistic discourse, or is inferable from it. However, one third of the additional semantic information contained in the gestures is not represented linguistically in the narrative nor is it inferable from it. In other words, a proportion of the imagistic gestures that accompany speech are absolutely critical to semantic communication. (shrink)

We examined the associations between the characteristics of Instagram users and the features of their photographs. Narcissism, life satisfaction, and loneliness were employed for user variables and the features at high- and low-levels were employed to analyze the Instagram photographs. An online survey was conducted with 179 university students, and their Instagram photographs, 25,394 in total, were collected and analyzed. High-level features were extracted using Computer Vision and Emotion Application Programming Interfaces in Microsoft Azure Cognitive Services, and low-level features were (...) extracted utilizing the program written by the authors. The results of correlation analysis indicate that narcissism, life satisfaction, and loneliness were significantly associated with a part of photograph features at high- and low-levels. The results of the predictive analysis suggest that narcissism, loneliness in total, and social loneliness could be predicted with acceptable accuracy from Instagram photograph features, while characteristics such as life satisfaction, family loneliness, and romantic loneliness could not be predicted. Implications of this research and suggestions for further research were presented. (shrink)

In this intriguing book, the concept of the soul is thoroughly investigated.

A crucial question here is what, exactly, the conditional in the naive truth/set comprehension principles is. In 'Logic of Paradox', I outlined two options. One is to take it to be the material conditional of the extensional paraconsistent logic LP. Call this "Strategy 1". LP is a relatively weak logic, however. In particular, the material conditional does not detach. The other strategy is to take it to be some detachable conditional. Call this "Strategy 2". The aim of the present essay (...) is to investigate Stragey 1. It is not to advocate it. The work is simply an extended exploration of the strategy, its strengths, its weaknesses, and the various dierent ways in which it may be implemented. In the first part of the paper I will set up the appropriate background details. In the second, I will look at the strategy as it applies to the semantic paradoxes. In the third I will look at how it applies to the set-theoretic paradoxes. (shrink)

This article will study a class of deduction systems that allow for a limited use of the modus ponens method of deduction. We will show that it is possible to devise axiom systems α that can recognize their consistency under a deduction system D provided that: (1) α treats multiplication as a 3-way relation (rather than as a total function), and that (2) D does not allow for the use of a modus ponens methodology above essentially the levels of Π1 (...) and Σ1 formulae. Part of what will make this boundary-case exception to the Second Incompleteness Theorem interesting is that we will also characterize generalizations of the Second Incompleteness Theorem that take force when we only slightly weaken the assumptions of our boundary-case exceptions in any of several further directions.

The best evidence in favour of a claim to knowledge warranties not the possibility of our not being wrong, so says the sceptic. Whatever grounds a putative knower has for some claim, always there exists a gap between the grounds and the claim. Anti-sceptical stands take the form of attempts either to bridge or close the gap. The Cartesian approach for bridging up the gap consists in specifying a guarantee for the subjective ground of beliefs that would secure them from (...) sceptical attacks and elevate them to the status of knowledge. The guarantee is to be sought in the goodness of a deity, which by virtue of its sheer goodness will ensure our not being led into deception in matters of evidences for knowledge-claims, provided our epistemic endowments are used responsibly. Some not satisfied with the Cartesian tradition sought the guarantee elsewhere—in some basic self-justifying and self-evident beliefs providing foundation to our system of beliefs, which conjoined with the evidences for our claims to knowledge make such claims immune to sceptical attacks.

The present pair of studies investigated the assessment, correlates, and evaluation of ?moral rebels? who follow their own moral convictions despite social pressure to comply. In Study 1, self, peer, and teacher ratings of adolescents' tendencies to be a moral rebel were positively intercorrelated.

Both adolescents and young (...) adults reported relatively favorable attitudes toward a morally rebellious peer, especially when they themselves had heightened ratings on this characteristic.

Remembering and forgetting are the two poles of the memory system. Consequently, any approach to memory should be able to explain both remembering and forgetting in order to gain a comprehensive and insightful understanding of the memory system. Can an enactive approach to memory processes do so? In this article I propose a possible way to provide a positive answer to this question. In line with some current enactive approaches to memory, I suggest that forgetting –similarly to remembering– might be (...) constituted within an embodied and active process. Within this process, some simulation and re-enactment paths would acquire more relevance than others. This acquired relevance would make the activation of other paths of recall less likely, thus preventing the memory system from engaging in some episodic simulations. These changes in the likelihood of activation of some paths of recall –the forgotten ones– can be accounted for in an enactive fashion by studying both “internal” and “external” re-enactment and simulation paths. With regard to the latter, I propose to examine the process of forgetting by considering the engagement and affective relation of an embodied agent with her field of affordances. I suggest that, in the case of emotion-laden memories, the agent’s decoupling from some affordances of the environment might contribute to the process of forgetting, in that it would reduce the agent’s opportunities for situated episodic simulations.

Model organisms are at the centre of progress in biology but attributing them an excessive representational power and concentrating on a limited group of them, although efficient for research, can have negative consequences, mainly of epistemic nature. Here, I argue that model organisms are exploratory models with a perspectival modelling function, and that a deflated representational power is needed for their proper use. In support of this argument, I will analyse developmental biology as a case study. Firstly, I show that (...) model organisms in developmental biology are not selected because of their representational capabilities, but mainly based on practical criteria. Secondly, I defend that the epistemic organization of developmental biology around questions fosters exploration and perspectival modelling and I propose that developmental biology is a ‘model organism situated knowledge’. Lastly, I use the study of the mechanisms of cell fate acquisition during early embryonic development in _C. elegans_ and mice as a case study to illustrate how a plurality of model organisms allows exploration and perspectival modelling. The use of model organisms for exploration and perspectival modelling, with a limited representational power, should allow more adequate inferences about human embryonic development and encourage the introduction of more model organisms for a comprehensive navigation of the space of possibilities.

Recent metaphor research has revealed that metaphor comprehension involves both categorization and comparison processes. This finding has triggered the following central question: Which property determines the choice between these two processes for metaphor comprehension? Three competing views have been proposed to answer this question: the conventionality view (Bowdle & Gentner, 2005), aptness view (Glucksberg & Haught, 2006b), and interpretive diversity view (Utsumi, 2007); these views, respectively, argue that vehicle conventionality, metaphor aptness, and interpretive diversity determine the choice between the categorization (...) and comparison processes. This article attempts to answer the question regarding which views are plausible by using cognitive modeling and computer simulation based on a semantic space model. In the simulation experiment, categorization and comparison processes are modeled in a semantic space constructed by latent semantic analysis. These two models receive word vectors for the constituent words of a metaphor and compute a vector for the metaphorical meaning. The resulting vectors can be evaluated according to the degree to which they mimic the human interpretation of the same metaphor; the maximum likelihood estimation determines which of the two models better explains the human interpretation. The result of the model selection is then predicted by three metaphor properties (i.e., vehicle conventionality, aptness, and interpretive diversity) to test the three views. The simulation experiment for Japanese metaphors demonstrates that both interpretive diversity and vehicle conventionality affect the choice between the two processes. On the other hand, it is found that metaphor aptness does not affect this choice. This result can be treated as computational evidence supporting the interpretive diversity and conventionality views.

The main research methodology of the philosophy of language is conceptual investigation and its main task is to clarify or disambiguate concepts. Undoubtedly, this is a basic consensus in the circles of the philosophy of language. However, with the development of the discipline, people have realized that the research of the philosophy of language should not stop at conceptual clarification or disambiguation, but it should tinker with or replace concepts and when necessary, create new concepts. These are the new developments (...) in the philosophy of language. Central to these developments is the research of conceptual engineering. What exactly is conceptual engineering? What practical values does it have? Centering around these questions, this paper presents an exploration of conceptual engineering itself with a view of revealing its essence and analyzing its practical implications. The basic tasks of conceptual engineering include conceptual design, implementation and evaluation. The practical value of conceptual engineering is that it pushes conceptual clarification or disambiguation toward conceptual construction. (shrink)

We propose an AI-assisted design concept exploration tool, the “Character Space Construction”. Concept designers explore and articulate the target product aesthetics and semantics in language, which is expressed using “Design Concept Phrases”, that is, compound adjective phrases, and contrasting terms that convey what are not their target design concepts. Designers often utilize this dichotomy technique to communicate the nature of their aesthetic and semantic design concepts with stakeholders, especially in an early design development phase. The CSC assists this designers' (...) cognitive activity by constructing a “Character Space”, which is a semantic quadrant system, in a structured manner. A CS created by designers with the assistance of the CSC enables them to discern and explain their design concepts in contrast with opposing terms. These terms in a CS are retrieved and combined in the CSC by using a knowledge graph. The CSC presents terms and phrases as lists of candidates to users from which users will choose in order to define the target design concept, which is then visualized in a CS. The participants in our experiment, who were in the “arts and design” profession, were given two conditions under which to create DCPs and explain them. One group created and explained the DCPs with the assistance of the proposed CSC, and the other did the same task without this assistance, given the freedom to use any publicly available web search tools instead. The result showed that the group assisted by the CSC indicated their tasks were supported significantly better, especially in exploration, as measured by the Creativity Support Index. (shrink)

It is well established that nursing practice produces considerable anxiety, and it can also give rise to envy and jealousy. While envy in nursing was identified in the literature more than 50 years ago, there remains a paucity of articles addressing either envy or jealousy for nurses. In a recent research study on current experiences of clinical practice, we analysed a fragment of nurses’ speech via Klein's theory of jealousy. The results revealed that the nurses expressed jealousy at the privilege (...) afforded to doctors. We argue that it is important to acknowledge jealousy in nursing practice because it has the potential for ‘spoiling’ effective care delivery and as such, can have detrimental ramifications in the health system. Also, jealousy may keep the nurse from fully focusing on their nursing practice in that it divides the nurse's attention and so limits the nurse's treatment of the patient. Nurses’ jealousy of doctors is a taboo topic in nursing, and yet it warrants serious consideration due to the potential deleterious consequences that can arise when this dynamic is present. (shrink)

The aim of the present study, based on data from 20 countries, is to identify the pattern of variables (at country, school and student levels), which are typical of students performing below the low international benchmark compared to students performing at the advanced performance benchmark, in the Progress in International Reading Literacy Study (PIRLS) 2006. The dependent variable of the analysis is a dichotomous variable, the values of which represent the two different performance groups of students. The independent variables are (...) two sets of Organisation for Economic Co-operation and Development educational indicators, variables from PIRLS 2006 Reading Curriculum Questionnaire data, variables and indices based on data obtained from questionnaires for teachers, schools, parents and students. The analysis is based on classification and regression trees, which is a full hierarchical non-parametric method suited to detecting and interpreting complex reciprocal influences between a large number of independent variables. The results show that pupils? performance can be predicted by the relationships between country-level variables (the changes in teachers? salaries at the top of the salary scale), school context variables (e.g. percentages of students from economically affluent home) and home educational resources and variables at student level (e.g. students? reading self-concept).

Most studies of motifs of biological regulatory networks focus on the analysis of asymptotical behaviours, but transient properties are rarely addressed. In the line of our previous study devoted to isolated circuits 19:172–178, 2003), we consider chorded circuits, that are motifs made of an elementary positive or negative circuit with a chord, possibly a self-loop. We provide detailed descriptions of the boolean dynamics of chorded circuits versus isolated circuits, under the synchronous and asynchronous updating schemes within the logical formalism. To (...) this end, we address the description of the trajectories in the dynamics of isolated circuits with coding techniques and adapt them for chorded circuits. The use of the logical modeling gives access to mathematical tools allowing complete analytical analysis of basic yet important motifs. In particular, we show that whatever the chosen updating rule, the dynamics depends on a small number of parameters. (shrink)
