Model validation in computational cognitive psychology often relies on methods drawn from the testing of theories in experimental physics. However, applications of these methods to computational models in typical cognitive experiments can hide multiple, plausible sources of variation arising from human participants and from stochastic cognitive theories, encouraging a “model fixed, data variable” paradigm that makes it difficult to interpret model predictions and to account for individual differences. This article proposes a likelihood‐based, “data fixed, model variable” paradigm in which models (...) are treated as stochastic processes in experiments with participant‐to‐participant variation that can be applied to a broad range of mechanistic cognitive architectures. This article discusses the implementation and implications of this view in model validation, with a concrete focus on a simple class of ACT‐R models of cognition. This article is not intended as a recipe for broad application of these preliminary, proof‐of‐concept methods, but as a framework for communication between statisticians searching for interesting problems in the cognitive modeling sphere, and cognitive modelers interested in generalizing from deterministic to stochastic model validation, in the face of random variation in human experimental data.

As the sustained and devastating extent of the coronavirus disease 2019 pandemic becomes apparent, a key focus of public scrutiny in the UK has centred on the novel legal and regulatory measures introduced in response to the virus. When those measures were first implemented in March 2020 by the UK Government, it was thought that human rights obligations would limit excesses of governmental action and that the public had more to fear from unwarranted intrusion into civil liberties. However, within the (...) first year of the pandemic’s devastation in the UK, a different picture has emerged: rather than through action, it is governmentalinactionthat has given rise to greater human rights concerns. The UK Government has been roundly criticized for its inadequate response, including missteps in decision-making, delayed implementation and poor enforcement of lockdown measures, abandonment of testing, shortages of critical resources and inadequate test and trace methods. In this article, we analyse the UK Government’s missteps and compare them with published international guidance; we also contrast the UK’s decisions with those taken by several other countries to understand how its actions and inactions have contributed to unfavourable outcomes. Using an analytical perspective that demonstrates how human rights are both a protection from the power of the state and a requirement that governmental powers are used to protect the lives, health and wellbeing of citizens, we argue that the UK Government’s failure to exercise their powers competently allowed the virus to spread without ensuring the country had the means to manage a high case load. This abject failure has led to one of the highest rates of deaths per capita worldwide. We offer several lessons that can be learnt from this unfortunate, but preventable, situation. (shrink)

Author Rizwaan Sabir, as a then-MA student at Nottingham University, became known as one-half of the “Nottingham Two” following his arrest along with Hicham Yezza in May 2008. They were detained for six days without charge on suspicion of terrorism for the possession of a document titled the Al Qaeda Training Manual, which was freely available on the internet and from bookstores. Sabir had downloaded it from a US government website for use as primary source material in his proposed PhD (...) research on armed Muslim groups. But Sabir’s arrest, detention, interrogation, and release without charge takes up only about one-fifth of the pages; the remainder covers subsequent events revealing the extent of the surveillance to...

The biological sciences provide ample opportunity and motivation for feminist interventions. These sciences are seen by many as an authority on human nature and are highly relevant to many issues of social justice and public policy. Feminist philosophy of biology focuses on the ethical and epistemic adequacy and responsibility of biological claims. This work is critical in the sense of identifying epistemically and ethically irresponsible knowledge claims, research practices, and dissemination of biological research regarding sex/gender, including ways that sex/gender interacts (...) with other social categories. In this chapter we describe classic themes in feminist philosophy of biology, with particular regard to research practices and metaphysical assumptions. We then go on to argue that these classic themes remain salient in contemporary neuroscientific investigations of human emotion and in feminist research on the evolution of human behavior. (shrink)

Causation in Physics demonstrates the importance of causation in the physical world. It details why causal mastery of natural phenomena is an important part of the effective strategies of experimental physicists. It develops three novel arguments for the viewpoint that causation is indispensable to the ontology of some of our best physical theories. All three arguments make much of the successes of experimental physics.

Recently, a new method of considering successful intentional thought suppression has emerged. This method, the think/no-think paradigm has been utilized over a multitude of settings and has fairly robustly demonstrated the ability to interfere with memory recall. The following experiment examined the effect of intentional thought suppression on recognition memory of nonverbalizeable shapes. In this experiment, participants learned word–shape targets. For some of the pairs, they rehearsed the shape when presented with the word; for others, they suppressed the shape when (...) presented with the word. Finally, participants were shown multiple shapes, one at a time, and asked to identify which they had previously seen as paired with a word. Results of the experiment indicated that, similar to results involving words, participants were less accurate in identifying suppressed shapes, as compared to rehearsed shapes. Implications of these findings are discussed. (shrink)

Promoting plant-based diets as a response to climate crisis has clear implications for producers of animal derived foods, but surprisingly little research considers their perspectives on this. Our exploration focused on farming strongly associated with meat production in Wales, UK. Mindful of polarised debates around plant-based diets, we considered dietary transition as an opportunity to produce for new markets. The first aim was to identify whether transition towards plant-based diets might trigger transformation of livestock agriculture. Findings indicate a potential trigger (...) event once livestock farmers are certain that consumer trends and climate mitigation require change. Livestock farmers who regard their meat as climate-friendly might resist transitions felt to unfairly disadvantage them. We then considered livestock farmers’ likely capacity to produce plant crops, and how this transformational capacity might be enhanced. Participants highlighted forms of financial and environmental inflexibility, plus social norms regarding “good” Welsh farmers, combining to make transformation risky. Transformational capacity might be enhanced through levering occupational and place attachments by portraying plant crops as a revival of historic practices from traditional farming landscapes. Improved linking capacity will also be beneficial, as producing for new markets requires connections to new supply chains, and learning across divisions within rural communities. We present these preliminary insights to livestock farmers’ attitudes and transformational capacity to inform future research with them to advance just agricultural transitions. Our study indicates potential to avoid confrontational discussion of dietary transition and we hope that others will pursue its focus on opportunities for farmers. (shrink)

Some of the dialogue in the Star Wars films has become deservedly iconic, instantly recognizable even to people unfamiliar with the series. Several human characters speak two or more languages. This chapter examines whether Chewbacca's noises work like a language. It considers a typical exchange between Chewbacca and Han Solo. The conclusion that these noises are not real language is so obvious as to be unnecessary: Chewbacca does not speak. The Star Wars films and Expanded Universe materials teem with processes, (...) objects, and entities that are unique to their fictional setting, are without counterparts in real life, and would need to be learned by someone encountering them for the first time. Conversely, if more and more people do start to use a word in a new way, eventually the newer usage will become its accepted meaning, either coexisting with an older meaning or superseding it.

Delving deeper into LEGO's products and marketing provides an important perspective on the development of the Research Institute set and LEGO's attempt to engage women in science. LEGO's own research shows that boys tend to build in a more linear fashion by replicating what is inside the box whereas girls prefer a more personal approach, to create their own story and to imagine themselves living inside the things they build. Sociologists have looked at every stage of children's development, and found (...) that parents treat babies differently as soon as the sex of the child is known. Language‐focused skills such as reading and writing are gendered feminine and thought of as girls' subjects, whereas science and physical education are considered masculine and treated as boys' subjects. Encouraging women to take up science and science‐related careers might not just be morally good, or good for women, but also important for the progress of science itself. (shrink)

Intelligence operations overwhelmingly focus on obtaining secrets (espionage) and the unauthorized disclosure of secrets by a public official in one political community to another (treason). It is generally understood that the principal responsibility of spies is to successfully procure secrets about the enemy. Yet, in this essay, I ask: Are spies and traitors ethically justified in using cyber operations not merely to acquire secrets (cyber espionage) but also to covertly manipulate or falsify information (cyber manipulation) to prevent atrocities? I suggest (...) that using cyber manipulation operations to parry atrocities is pro tanto morally permissible and, on occasion, required. (shrink)

It appears that spouses have less reason to hold each other to a norm of monogamy than to reject the norm. The norm of monogamy involves a restriction of spouses' aeeess to two things of value: sex and erotic love. This restriction initially appears unwarranted but can be justified. There is reason for spouses to aeeept the norm of monogamy if their marriage satisfies three conditions. Otherwise, there is reason to permit non-monogamy. Some spouses have reason to accept the norm (...) of monogamy because this will avoid reasonable hurt and prevent diversion of resourees needed to sustain the marriage. Other spouses have reason to permit non-monogamy to allow the spouses access to aspects of a well-rounded life. The choice to be either monogamous or non-monogamous ean also be non-instrumentally valuable if chosen for the right reasons. (shrink)

ABSTRACT: This 1974 paper builds on our 1969 paper (Corcoran-Weaver [2]). Here we present three (modal, sentential) logics which may be thought of as partial systematizations of the semantic and deductive properties of a sentence operator which expresses certain kinds of necessity. The logical truths [sc. tautologies] of these three logics coincide with one another and with those of standard formalizations of Lewis's S5. These logics, when regarded as logistic systems (cf. Corcoran [1], p. 154), are seen to be (...) equivalent; but, when regarded as consequence systems (ibid., p. 157), one diverges from the others in a fashion which suggests that two standard measures of semantic complexity may not be as closely linked as previously thought. -/- This 1974 paper uses the linear notation for natural deduction presented in [2]: each two-dimensional deduction is represented by a unique one-dimensional string of characters. Thus obviating need for two-dimensional trees, tableaux, lists, and the like—thereby facilitating electronic communication of natural deductions. The 1969 paper presents a (modal, sentential) logic which may be thought of as a partial systematization of the semantic and deductive properties of a sentence operator which expresses certain kinds of necessity. The logical truths [sc. tautologies] of this logic coincides those of standard formalizations of Lewis’s S4. Among the paper's innovations is its treatment of modal logic in the setting of natural deduction systems--as opposed to axiomatic systems. The author’s apologize for the now obsolete terminology. For example, these papers speak of “a proof of a sentence from a set of premises” where today “a deduction of a sentence from a set of premises” would be preferable. 1. Corcoran, John. 1969.

In an attempt to improve upon Alexander Pruss’s work (The principle of sufficient reason: A reassessment, pp. 240–248, 2006), I (Weaver, Synthese 184(3):299–317, 2012) have argued that if all purely contingent events could be caused and something like a Lewisian analysis of causation is true (per, Lewis’s, Causation as influence, reprinted in: Collins, Hall and paul. Causation and counterfactuals, 2004), then all purely contingent events have causes. I dubbed the derivation of the universality of causation the “Lewisian argument”. The (...) Lewisian argument assumed not a few controversial metaphysical theses, particularly essentialism, an incommunicable-property view of essences (per Plantinga’s, Actualism and possible worlds, reprinted in: Davidson (ed.) Essays in the metaphysics of modality, 2003), and the idea that counterfactual dependence is necessary for causation. There are, of course, substantial objections to such theses. While I think a fight against objections to the Lewisian argument can be won, I develop, in what follows, a much more intuitive argument for the universality of causation which takes as its inspiration a result from Frederic B. Fitch’s work (J Symb Logic 28(2):135–142, 1963) [with credit to who we now know was Alonzo church’s, Referee Reports on Fitch’s Definition of value, in: (Salerno (ed.), New essays on the knowability paradox, 2009)] that if all truths are such that they are knowable, then (counter-intuitively) all truths are known. The resulting Church–Fitch proof for the universality of causation is preferable to the Lewisian argument since it rests upon far weaker formal and metaphysical assumptions than those of the Lewisian argument.

Influenced by Sachs’ ‘activist identity’ I propose that pre-service teacher education or initial teacher education, as I will refer to it, could, and indeed should, encourage a new form of teacher; the ‘teacher-agent.’ This teacher-agent would be aware of the pressures and dictates of the neo-liberal educational culture and its ensuing performative discourse, and choose to resist it, in favour of a more holistic view of education. This view of education encourages inclusive, creative and democratic forms of education concerned with (...) encouraging a social conscience in children and young people, as well as seeing education as concerned with the whole child. These more holistic approaches to education could include pedagogical approaches such as Philosophy for Children, Rights’ Respecting Education and Slow Pedagogy, which can not only provide a more balanced understanding and deeper experience of education for both teachers and pupils, but can also help teachers to resist the debilitating impact of the neo-liberal performative discourse, potentially also thus impacting on their wellbeing and ability to retain their integrity as professionals. This may also have the potential to halt the rapid exodus of new teachers from the profession. It is my contention, that engaging with pedagogies such as P4C in this new iteration of ITE could help not only to encourage the Student Teacher-Agent, but also, as a consequence, develop the Citizen-Agent in the children they are teaching. In this paper I consider four key areas where I propose P4C could play a role in this alternative model of Initial Teacher Education; Democracy in action, the teacher as Teacher-Facilitator, a space for co-construction of knowledge, and encouraging Social Justice.

The introduction of the new National Curriculum in England, was initially viewed with suspicion by practitioners, uneasy about the radical departure from the previous National Curriculum, in both breadth and scope of the content. However, this paper will suggest that upon further reflection the brevity of the content could lend itself to a total re-evaluation of the approach to curriculum planning in individual schools. This paper will explore how, far from creating a burden of extra curriculum content, Philosophy for Children (...) can in fact be a driver for the whole primary curriculum. With the renewed focus on Spiritual, Moral, Social and Cultural Development in England, it will investigate the potential for P4C to engage and enhance these areas, which often are neglected or side-lined in the primary curriculum. It will consider the benefits to a class, and indeed school, of creating communities of enquiry and how they can influence school ethos, values and vision. The paper will also share reflections on my own practice as a new trainer with SAPERE over the past two years of training student teachers, colleagues at the university as well as local primary school teachers and head teachers. In addition it will share examples of good practice from three schools where Philosophy for Children has been successfully integrated in a variety of models across the whole school curriculum.

Marketers use autobiographical advertising as a means to create nostalgia for their products. This research explores whether such referencing can cause people to believe that they had experiences as children that are mentioned in the ads. In Experiment 1, participants viewed an ad for Disney that suggested that they shook hands with Mickey Mouse as a child. Relative to controls, the ad increased their confidence that they personally had shaken hands with Mickey as a child at a Disney resort. The (...) increased confidence could be due to a revival of a true memory or the creation of a new, false one. In Experiment 2, participants viewed an ad for Disney that suggested that they shook hands with an impossible character (e.g., Bugs Bunny). Again, relative to controls, the ad increased confidence that they personally had shaken hands with the impossible character as a child at a Disney resort. The increased confidence is consistent with the notion that autobiographical referencing can lead to the creation of false or distorted memory. ᭧ 2002 John Wiley & Sons, Inc. (shrink)

ABSTRACTThis article considers some analogies for religion which are so common in our ordinary language that they might pass without notice. I explore five in detail to show how each in different ways limits what we can say, and indeed think, about religion. By using multiple religious belonging as an example, I am able to compare the things we ordinarily say about religion with the complexities of real, lived religion and illustrate some of the ways in which our analogies for (...) religion fall short. Many of these analogies are so ‘natural’ – so deeply embedded in the ways ordinary language works – that without this specific attention, they can shape what can be said about religion without the speaker noticing. Often, this makes things which the sociological evidence shows people are getting on and doing, like practising multiple religious belonging, seem ‘impossible’ when we try to describe them. By paying attention to the analogies which underlie this sensation, I am able to show that a wider variety of analogies, used with more conscious attention, can be employed to allow us to think more clearly about complex lived religion, including multiple religious belonging.

After an introduction which demonstrates the failure of the equational analogue of Beth?s definability theorem, the first two sections of this paper are devoted to an elementary exposition of a proof that a functional constant is equationally definable in an equational theory iff every model of the set of those consequences of the theory that do not contain the functional constant is uniquely extendible to a model of the theory itself.Sections three, four and five are devoted to applications and extensions (...) of this result.Topics considered here include equational definability in first order logic, an extended notion of definability in equational logic and the synonymy of equational theories.The final two sections briefly review some of the history of equational logic.

Pacifism is routinely criticized as sectarian, incoherent, and preoccupied with moral purity at the expense of responsibility. The author contends that the pacifism of John Howard Yoder is vulnerable to none of these charges and defends this claim by establishing parallels between Yoder's analysis of killing and Augustine's analysis of lying. Although, within the terms of his own argument, Augustine's rejection of all lying as unjust is consistent with his condoning of some killing as just, the author shows that given (...) a different conception of the defining characteristic of God , Augustine's theological argument against lying would become an argument against violence. The author therefore suggests that Yoder's rejection of killing is no more sectarian, incoherent, or irresponsible than Augustine's rejection of lying. (shrink)

The chorion genes of Drosophila are amplified in response to developmental signals in the follicle cells of the ovary prior to their transcription. Their expression is regulated both temporally and spatially within this tissue. They thus serve as models both for the regulation of DNA replication and of developmental transcription. The regulatory elements for DNA amplification have been delineated. Their analysis reveals that amplification is mediated by several regulatory regions and initiates at defined origins within the chorion cluster. Proteins involved (...) in amplification are being identified both by mutations affecting amplification and by DNA binding studies. Regulatory elements for temporal as well as spatial control of chorion gene, expression have been characterized, and two candidate transcription factor genes have been cloned. (shrink)

Seeking new language for the Divine has encouraged Christian and Jewish feminists to explore other religious traditions which are richer in feminine language for God, and in some cases to borrow parts of what they find for their own use. However, these other religious traditions are often socially and politically less powerful, and borrowing their language and practice has ethical implications. Especially because the ethical dimensions of liturgy are bound up with theological issues, religious feminists have a moral duty to (...) consider these questions in which there are rarely if ever any easy answers.

Debates over physician-assisted suicide comprise a small portion of broader culture wars. Their role in the culture wars obscures an under-acknowledged consensus between those who support PAS and those who oppose it. Drawing insights from personalism, this essay situates PAS within larger moral obligations of solidarity with the dying and their caregivers. The contributions of Roman Catholic personalism relocate debates over PAS and allow us to harness shared moral impulses.

Among the complete ℵ0-categorical theories with finite non-logical vocabularies, we distinguish three classes. The classification is obtained by looking at the number of bound variables needed to isolated complete types. In classI theories, all types are isolated by quantifier free formulas; in classII theories, there is a leastm, greater than zero, s.t. all types are isolated by formulas in no more thanm bound variables: and in classIII theories, for eachm there is a type which cannot be isolated inm or fewer (...) bound variables. ClassII theories are further subclassified according to whether or not they can be extended to classI theories by the addition of finitely many new predicates. Alternative characterizations are given in terms of quantifier elimination and homogeneous models. It is shown that for each primep, the theory of infinite Abelian groups all of whose elements are of orderp is classI when formulated in functional constants, and classIII when formulated in relational constants.

Armed reprisals are the limited use of military force in response to unlawful actions perpetrated against states. Historically, reprisals provided a military remedy for states that had been wronged by another state without having to resort to all-out war in order to counter or deter such wrongful actions. While reprisals are broadly believed to have been outlawed by the UN Charter, states continue to routinely undertake such self-help measures. As part of the roundtable, “The Ethics of Limited Strikes,” this essay (...) examines the doctrine of armed reprisals in light of recent instances of states using force “short of war” in this manner. We argue that the ban on reprisals has been largely ignored by states, and that recent attempts to apply the laws of armed conflict to the cyber domain are further weakening this prohibition. We conclude that this is a potentially dangerous development that lowers the bar for resorting to military force, risking escalation and thereby further destabilizing the international system.
