There are growing concerns that increased screen device usage may have a detrimental impact on classroom behaviour and attentional focus. The consequences of screen use on child cognitive functioning have been relatively under-studied, and results remain largely inconsistent. Screen usage may displace the time usually spent asleep. The aim of this study was to examine associations between screen use, behavioural inattention and sustained attention control, and the potential modifying role of sleep. The relations between screen use, behavioural inattention, sustained attention (...) and sleep were investigated in 162 6- to 8-year-old children, using parent-reported daily screen use, the SWAN ADHD behaviour rating scale, The sustained attention to response task and the children’s sleep habits questionnaire. Tablet use was associated with better sustained attention performance but was not associated with classroom behavioural inattention. Shorter sleep duration was associated with poorer behavioural inattention and sustained attention. Sleep quality and duration did not act as mediators between screen usage and behavioural inattention nor sustained attention control. These findings suggest that careful management of the amount of time spent on electronic screen devices could have a beneficial cognitive impact on young children. The results also highlight the critical role of sleep in enhancing both behavioural attention and sustained attention, which are essential for supporting cognitive development and learning. (shrink)

We frequently speak of certain things or phenomena being built out of or based in others. Making Things Up concerns these relations, which connect more fundamental things to less fundamental things: Karen Bennett calls these 'building relations'. She aims to illuminate what it means to say that one thing is more fundamental than another.

This book discusses the notion that quantum gravity may represent the "breakdown" of spacetime at extremely high energy scales. If spacetime does not exist at the fundamental level, then it has to be considered "emergent", in other words an effective structure, valid at low energy scales. The author develops a conception of emergence appropriate to effective theories in physics, and shows how it applies (or could apply) in various approaches to quantum gravity, including condensed matter approaches, discrete approaches, and loop (...) quantum gravity.

Relationships between current theories, and relationships between current theories and the sought theory of quantum gravity (QG), play an essential role in motivating the need for QG, aiding the search for QG, and defining what would count as QG. Correspondence is the broad class of inter-theory relationships intended to demonstrate the necessary compatibility of two theories whose domains of validity overlap, in the overlap regions. The variety of roles that correspondence plays in the search for QG are illustrated, using examples (...) from specific QG approaches. Reduction is argued to be a special case of correspondence, and to form part of the definition of QG. Finally, the appropriate account of emergence in the context of QG is presented, and compared to conceptions of emergence in the broader philosophy literature. It is argued that, while emergence is likely to hold between QG and general relativity, emergence is not part of the definition of QG, and nor can it serve usefully in the development and justification of the new theory.

In seeking an answer to the question of what it means for a theory to be fundamental, it is enlightening to ask why the current best theories of physics are not generally believed to be fundamental. This reveals a set of conditions that a theory of physics must satisfy in order to be considered fundamental. Physics aspires to describe ever deeper levels of reality, which may be without end. Ultimately, at any stage we may not be able to tell whether (...) we've reached rock bottom, or even if there is a base level – nevertheless, I draft a checklist to help us identify when to stop digging, in the case where we may have reached a candidate for a final theory. Given that the list is – according to (current) mainstream belief in high-energy physics – complete, and each criterion well-motivated, I argue that a physical theory that satisfies all the criteria can be assumed to be fundamental in the absence of evidence to the contrary (i.e., I argue that the necessary conditions are jointly sufficient for a claim of fundamentality in physics).

Empirical work on and common observation of the emotions tells us that our emotions sometimes key us to the presence of real and important reason-giving considerations without necessarily presenting that information to us in a way susceptible of conscious articulation and, sometimes, even despite our consciously held and internally justified judgment that the situation contains no such reasons. In this paper, I want to explore the implications of the fact that emotions show varying degrees of integration with our conscious agency—from (...) none at all to quite substantial—for our understanding of our rationality, and in particular for the traditional assumption that weakness of the will is necessarily irrational.

This article explores the processes through which Australian recipients select unknown donors for use in assisted reproductive technologies and speculates on how those processes may affect the future life of the donor-conceived person. I will suggest that trust is an integral part of the exchange between donors, recipients, and gamete agencies in donor conception and heavily informs concepts of relatedness, race, ethnicity, kinship, class, and visibility. The decision to be transparent about a child’s genetic parentage affects recipient parents’ choices of (...) donor, about who is allowed to “know” children’s genetic backgrounds, and how important it is to be able to “pass” as an unassisted conception. In this way, recipients must trust the process, institutions, and individuals involved in their treatment, as well as place trust in the future they imagine for their child. The current market for donor gametes reproduces normative conceptions of the nuclear family, kinship, and relatedness by facilitating “matching” donors to recipients by phenotype and cultural affinities. Recipient parents who choose not to prioritize “matching,” and actively disclose the process of children’s conceptions, may embark on a project of queering heteronormative family structures and place great trust in both their own children and changing social attitudes to reduce stigma and generate acceptance for non-traditional families.

The interventionist account of causation has been largely dismissed as a serious candidate for application in physics. This dismissal is related to the problematic assumption that physical causation is entirely a matter of dynamical evolution. In this article, I offer a fresh look at the interventionist account of causation and its applicability to thermodynamics. I argue that the interventionist account of causation is the account of causation that most appropriately characterizes the theoretical structure and phenomenal behavior of thermodynamics.

I identify a controversial hypothesis in evolutionary biology called the plasticity-first hypothesis. I argue that the plasticity-first hypothesis is underdetermined and that the most popular means of studying the plasticity-first hypothesis are insufficient to confirm or disconfirm it. I offer a strategy for overcoming this problem. Researchers need to develop a richer middle range theory of plasticity-first evolution that allows them to identify distinctive empirical traces of the hypothesis. They can then use those traces to discriminate between rival explanations of (...) evolutionary episodes. The best tools for developing such a middle range theory are experimental evolution and formal modelling. (shrink)

Resident microorganisms, known as the microbiota, are essential for many physiological functions including protection against pathogens. Microbiota is indeed required for proper immune system development and function, and can also host-independently protect against infections. Thus, a co-constructed view of host protection involving both host and microbiota, named ’co-immunity,’ has been proposed, and the idea of an ’immunological holobiont’ has been suggested. Yet this view of co-immunity might be too limited, as experimental work has shown that the immune system is involved (...) in functions other than protection, essentially development and repair. Microbiota, through co-immunity, is thereby most likely involved in these functions, although strong evidence is currently lacking. Moreover, as our point of view is mainly host-centered, we may miss the implications of co-immunity at broader scales, including cellular and population levels. Intriguingly, co-immunity effects could be beneficial for one function and/or one level, while being detrimental for others. All these elements should be taken into consideration for microbiota manipulation, in order to avoid potentially harmful side effects. (shrink)

Davidson has argued that the phenomenon of malapropism shows that languages thought of as social entities cannot be prior in the account of communication. This may be taken to imply that Dummett's belief, that language is prior in the account of thought, cannot be retained. This paper criticises the argument that takes Davidson from malapropism to the denial of the priority of language in the account of communication. It argues, against Davidson, that the distinction between word meaning and what speakers (...) mean by words, used by Davidson to account for metaphor, suffices to account for malapropism. The reasons for the failure of Davidson's argument are used to throw light on what is meant by the priority of language over thought, and to argue that the priority thesis is ambiguous. (shrink)

Self-tracking practices include the use of personal data-gathering apps, wearable devices, and data analysis tools to record patterns from daily activities, as well as the organization, visualization, and analysis of this data. This paper draws on theories of digital labour and feminist political economy to build a framework of digital productive labour that highlights the exploitation of activities external to the formal labour relationship. Self-tracking practices are analysed through the lens of digital productive insofar as they fulfill three roles: they (...) generate the content necessary for sustaining digital networks and producing data that can be captured in commodity form; they aid in the reproduction of the social factory’s labour force; and they cultivate subjectivities amenable to consumption and production in contemporary capitalism. The paper examines the production and commodification of data, highlighting the algorithmic means by which self-trackers are separated from the financial value of their data. This is connected to feminist analyses of unpaid labour, with particular attention to self-tracking’s role as a contemporary form of reproductive labour that replenishes the labour force. Finally, the paper provides an analysis of the themes of self-knowledge, self-discovery, and gamification to understand how these frame self-trackers’ understanding of themselves as labourers, thus reproducing and deepening capitalist subjectivities. The paper concludes by considering self-tracking through the lens of the exploitation of life ‘outside’ the official labour relationship. (shrink)

This book explains how gossip contributes to knowledge. Karen Adkins marshals scholarship and case studies spanning centuries and disciplines to show that although gossip is a constant activity in human history, it has rarely been studied as a source of knowledge. People gossip for many reasons, but most often out of desire to make sense of the world while lacking access to better options for obtaining knowledge. This volume explores how, when our access to knowledge is blocked, gossip becomes (...) a viable path to knowledge attainment, one that involves the asking of questions, the exchange of ideas, and the challenging of preconceived notions.

Aristotle’s theory of spontaneous generation offers many puzzles to those who wish to understand his theory both within the context of his biology and within the context of his more general philosophy of nature. In this paper, I approach the difficult and vague elements of Aristotle’s account of spontaneous generation not as weaknesses, but as opportunities for an interesting glimpse into the thought of an early scientist struggling to reconcile evidence and theory. The paper has two goals: to give as (...) charitable and full an account as possible of what Aristotle’s theory of spontaneous generation was, and to examine some of its consequences; and to reflect on Aristotle as a scientist, and what his comments reveal about how he approached a difficult problem. In particular, I propose that the well-recognized problem of the incompatibility between Aristotle’s concept of spontaneity and his theory of spontaneous generation presents an opportunity for insight into his scientific methodology when approaching ill-understood phenomena.

Although databases have been well-defined and thoroughly discussed in the computer science literature, the actual users of databases often have varying definitions and expectations of this essential computational infrastructure. Systems administrators and computer science textbooks may expect databases to be instantiated in a small number of technologies, but there are numerous examples of databases in non-conventional or unexpected technologies, such as spreadsheets or other assemblages of files linked through code. Consequently, we ask: How do the materialities of non-conventional databases differ (...) from or align with the materialities of conventional relational systems? What properties of the database do the creators of these artifacts invoke in their rhetoric describing these systems—or in the data models underlying these digital objects? To answer these questions, we conducted a close analysis of four non-conventional scientific databases. By examining the materialities of information representation in each case, we show how scholarly communication regimes shape database materialities—and how information organization paradigms shape scholarly communication. These cases show abandonment of certain constraints of relational database construction alongside maintenance of some key relational data organization strategies. We discuss the implications that these relational data paradigms have for data use, preservation, and sharing, and discuss the need to support a plurality of data practices and paradigms. (shrink)

We tested the good genes ovulatory shift hypothesis through speed-dating, an ecologically valid paradigm with real life consequences. Fifteen speed-dating sessions of 262 single Asian Americans were held. We analyzed 850 speed-dates involving 132 men and 100 normally ovulating women, finding ovulatory shifts in the desirability of men with more masculine facial measurements (smaller eye–mouth–eye angle, larger lower face to full face height ratio, and smaller facial width to lower face height ratio) in the predicted direction. However, there was no (...) support for ovulatory shifts in preferences for men’s self-reported height. In addition, the expected shifts were not found for women’s second date offers to men. Therefore, with natural stimuli and in a competitive dating scenario, we partially replicated previously documented ovulatory shifts in women’s preferences for men. (shrink)

This study has two agendas: to interrogate popular notions of religion by reading it, out of Derrida and Certeau, as a signifier for a situated historical scene; and to show the existential philosophy of Beauvoir as a performance of that scene. In particular, it shows how the structure of relationships she presents in her ethics clearly reproduces the rhythms of the scene of religion. One of the implications of this reproduction is that existential philosophy can only emerge in the context (...) of religion, and is necessarily an iteration of religion. The other implication is that we might reassess how we code the category ‘religion’ in our public and private discourse, with all the disruption that such a different coding might entail. (shrink)

Paul Needham has claimed in several recent papers that Dalton’s chemical atomism was not explanatory. I respond to his criticism of Dalton by arguing that explanation admits of degrees and that under a view that allows for a spectrum of explanatory value, it is possible to see ample worth in Dalton’s atomistic explanations. Furthermore, I argue that even Duhem, who rejected atomism, acknowledged the explanatory worth of Dalton’s atomism.

Historical research on John Dalton has been dominated by an attempt to reconstruct the origins of his so-called "chemical atomic theory". I show that Dalton's theory is difficult to define in any concise manner, and that there has been no consensus as to its unique content among his contemporaries, later chemists, and modern historians. I propose an approach which, instead of attempting to work backward from Dalton's theory, works forward, by identifying the research questions that Dalton posed to himself and (...) attempting to understand how his hypotheses served as answers to these questions. I describe Dalton's scientific work as an evolving set of puzzles about natural phenomena. I show how an early interest in meteorology led Dalton to see the constitution of the atmosphere as a puzzle. In working on this great puzzle, he gradually turned his interest to specifically chemical questions. In the end, the web of puzzles that he worked on required him to create his own novel philosophy of chemistry for which he is known today. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 34.1 (2001) 21-37 [Access article in PDF] Conscience and the Concealments of Metaphor in Hobbes's Leviathan Karen S. Feldman Introduction Conscience is not a topic of terribly heated debate in Hobbes research. 1 Nevertheless, my claim in this article is that conscience in the Leviathan, which Hobbes poses as an example of the dangers of metaphor, is not merely an example of the dangers of (...) metaphor, but rather is the most dangerous metaphor, the metaphor that corrupts knowledge and thereby makes error and deception possible. Hobbes's brief account of conscience, which appears in the chapter of Leviathan on the ends of discourse, tells the story of the insinuation of metaphor into proper nomenclature; however, his example of the metaphorical use of the word conscience turns the story into one in which public knowledge itself is made private and thereby corrupted. Moreover, according to the story, private conscience is itself invented by means of a metaphor; it is in effect metaphorized into being. 2 With the emergence of private conscience, the potential of privatization expands from the privatization of the meaning of words to an entire private sphere of opinion. The metaphorical corruption of conscience invents a new understanding of knowledge as isolated from other witnesses, and the resultant privatization of truth lends itself to the corruption of that truth. Thus, whereas Hobbes characterizes the wrong use of names (of which metaphor is an instance) as a threat to accurate judgment and reason (L 22-23, 34, 161-62), as I will argue in the sections following, Hobbes's demand for the preservation of proper meaning in Leviathan corresponds to an anxiety regarding privacy and its peculiar potential for corrupting truth and knowledge. Hobbes's worries as to the dangers that metaphor poses to the stability of the commonwealth thereby converge with his worries about the dangers of conscience to the principle of public authority (cf. Strong 1993). [End Page 21] Hobbes's condemnations of conscience In Leviathan, conscience is condemned as a source of principles of human decision and action in a commonwealth. The problem with conscience as a principle of action is that it renders each individual inventor of his own rules and judge of his own actions. In brief, individual conscience is incommensurable with the public authority that defines a commonwealth: Another doctrine repugnant to civil society, is, that whatsoever a man does against his conscience, is sin; and it dependeth on the presumption of making himself judge of good and evil. For a man's conscience, and his judgment is the same thing, and as the judgment, so also the conscience may be erroneous. Therefore, though he that is subject to no civil law, sinneth in all he does against his conscience, because he has no other rule to follow but his own reason; yet it is not so with him that lives in a commonwealth; because the law is the public conscience, by which he hath already undertaken to be guided. Otherwise in such diversity, as there is of private consciences, which are but private opinions, the commonwealth must needs be distracted, and no man dare to obey the sovereign power, further than it shall seem good in his own eyes. (L 311) In this account, conscience is not just inferior to civil law as a principle guiding action, but at odds with civil society and the good of the commonwealth. The fact that conscience is private renders it problematic for the commonwealth for several reasons: First, as privately invented, it may be erroneous. Likewise, because it is private, conscience does not possess any binding power outside the individual, private sphere. Each person may be bound by his own conscience, but insofar as consciences differ, standards of action differ, and this leads to the undermining and distraction of the commonwealth. Likewise, private consciences may be divergent from one another, and the conflicts in private judgment produce conflicting actions that disturb the peace of the commonwealth. This rule of privacy is, moreover, associated with primitive life and with the state of nature... (shrink)

We examine recent work in cognitive neuroscience that investigates brain networks. Brain networks are characterized by the ways in which brain regions are functionally and anatomically connected to one another. Cognitive neuroscientists use various noninvasive techniques (e.g., fMRI) to investigate these networks. They represent them formally as graphs. And they use various graph theoretic techniques to analyze them further. We distinguish between knowledge of the graph theoretic structure of such networks (structural knowledge) and knowledge of what instantiates that structure (nonstructural (...) knowledge). And we argue that this work provides structural knowledge of brain networks. We explore the significance of this conclusion for the scientific realism debate. We argue that our conclusion should not be understood as an instance of a global structural realist claim regarding the structure of the unobservable part of the world, but instead, as a local structural realist attitude towards brain networks in particular. And we argue that various local approaches to the realism debate, i.e., approaches that restrict realist commitments to particular theories and/or entities, are problematic insofar as they don't allow for the possibility of such a local structural realist attitude.

Using data from 52 in-depth interviews with working-class and professional men and women, I examine gender differences in friendships. Men and women respond to global questions about friendship in culturally specific ways. Men focus on shared activities, and women focus on shared feelings. Responses to questions about specific friends, however, reveal more variation in same-sex friendships than the literature indicates. Men share feelings more, whereas women share feelings less; furthermore, the extent to which they do so varies by class. I (...) argue that conceptualizing gender as an ongoing social construction explains the data better than do psychoanalytic or socialization accounts. (shrink)

I argue that the framing of environmental justice issues in terms of distribution is problematic. Using insights about the connections between institutions of human oppression and the domination of the natural environment, as well as insights into nondistributive justice, I argue for a nondistributive model to supplement, complement, and in some cases preempt the distributive model. I conclude with a discussion of eight features of such a nondistributive conception of justice.

This paper reports on the long-term effectiveness of a non-formal co-curricular educational program based on a campus ecogarden at a Hong Kong university in developing pro-sustainability awareness, attitudes and behavior among undergraduate students. This service-based, nature-based experiential learning program, termed the Ecogarden Farmer and Biodiversity Surveyor, has been running at the university since 2015. The program is divided into two consecutive phases: a training phase comprising various learning activities and a successive internship phase consisting of the all-round practical tasks involved (...) in managing the garden. A retrospective evaluation of the program using phenomenographic approach and content analysis was adopted to reveal the diversity of students’ learning experience, as the indicators of the success of the program. Of 112 participants from 4 cohorts, 32 completed online questionnaires, and semi-structured interviews were successfully conducted with twelve participants, three from each of the four cohorts. The results indicated that the program’s outcomes could be categorized into five themes. Most outcomes fit into the theme ‘an increase in knowledge and skill level,’ followed by ‘rise in environmental awareness,’‘facilitation of personal growth,’ and ‘enhancement of career development.’ Many structural experiences revealed may suggest the success of the program. The longer the participants had participated in the program, the more in-depth and diversified reflection of the senior participants relating to personal development were mentioned. This study provides critical insights into the validity of retrospective program evaluation for assessing the long-term impact of EfS programs by introducing a cross-sectional study of different cohorts as a serial time-point sampling strategy.

This discussion contributes to the ongoing debates regarding the (re)sexualisation of female bodies in popular and visual culture. Visual texts display the upper middle-class white female as the carrier of mainstream neo-liberal values in Western societies, and the success of this approach is the twinning of the culture of individualism, self-interest and market values with feminist vocabularies; namely, choice, freedom and independence. Drawing on a broad feminist scholarship that includes discussions on the influence of the HBO series Sex and the (...) City, semiotic analysis is combined with intersectionality to gain an understanding of how gender, class and sexuality shape and reinforce whiteness as entitled to luxury in an advertising campaign for Michael Kors luxury goods. Contemporary representations have expanded to include representations of affluent women who appear to have it all. These new post-feminist subjectivities promote an aesthetic of wealth, to display privileged whiteness, heterosexuality, normative Western beauty ideals and individualism. An intersectional approach reveals the apparent neutrality of neo-liberal values as being an expression of whiteness, specifically in representations of white women as economically independent neo-liberal subjects who display their status through the conspicuous consumption of luxury brands.

We critique the metaphysical ecology developed by J. Baird Callicott in “The Metaphysical Implications of Ecology” in light of what we take to be the most viable attempt to provide an inclusive theoretical framework for the wide variety of extant ecosystem analyses—namely, hierarchy theory. We argue that Callicott’s metaphysical ecology is not consonant with hierarchy theory and is, therefore, an unsatisfactory foundation for the development of an environmental ethic.

Thomas Hofweber's Ontology and the Ambitions of Metaphysics is ambitious, thought-provoking, and a good read. It expands upon a project he's developed in several previous papers—a project that seamlessly weaves together both metaphysics and metametaphysics.

Since I cannot do justice to all of it, I hope my (...) fellow symposiasts will take up parts of the book that I neglect. There is a lot of good stuff in there. (shrink)

This article explores the role of religion in Ottoman political legitimation. It shows that the Ottoman rulers were interested in a much more expansive, diverse form of political legitimation that included Islamic religious legitimation, but also used toleration and sultanic law to construct a more capacious form of political legitimation that included Muslim and non-Muslim populations of the empire.

Naturalist philosopher Robert Corrington begins his chapter in Frontiers in American Philosophy, volume 1, by asserting that "the current obsession with language and with written texts has blunted the generic drive of hermeneutics and its more legitimate quest for a categorical structure that is truly responsive to the various dimensions of meaning manifest in the ongoing human process. . . . The deeper emancipatory forces of nature and history remain bereft of a proper location for their appearance in nondestructive social (...) orders."1 This critique is presumably directed at poststructuralist theories in which language and text are all there is, the world is made up of a play of signs, and reliance on ontology or ..
