Software piracy is a serious problem in the software industry. Software authors and publishing companies lose revenue when pirated software rather than legally purchased software is used. Policy developers are forced to invest time and money into restricting software piracy. Much of the published research literature focuses on software piracy by end-users. However, end-users are only able to copy software once the copy protection has been removed by a ‘cracker’. This research aims to explore why, if copy protection is so (...) difficult to remove, do crackers invest their skill and time in this activity instead of more lucrative and legal employment. This study develops a framework of neutralisation, justification and motivation and goes directly to the initial software crackers to determine what motivates their activities. The study first applies this framework in an anonymous online survey of crackers. The study then conducts cognitive interviews with eight crackers to explore and further validate the survey’s findings. The study finds the challenge of removing the copy protection from software as the strongest motivation for the actions of crackers. Desire for social participation, while found to be rewarding, was considered unnecessary for crackers to continue their actions. Higher social status was not a motivational factor but was a perceived by-product of cracking. The study also raises areas for future research. (shrink)

Is it possible for an individual that has gone out of being to come back into being again? The English Aristotelian, Thomas White, argued that it is not. Thomas Hobbes disagreed, and used the case of the Ship of Theseus to argue that individuals that have gone out of being may come back into being again. This paper provides the first systematic account of their arguments. It is doubtful that Hobbes has a consistent case against White. Still his criticism may (...) have prompted White to clarify his views on identity over time in his later work. (shrink)

We prove that the problem of determining the minimum propositional proof length is NP- hard to approximate within a factor of 2 log 1 - o(1) n . These results are very robust in that they hold for almost all natural proof systems, including: Frege systems, extended Frege systems, resolution, Horn resolution, the polynomial calculus, the sequent calculus, the cut-free sequent calculus, as well as the polynomial calculus. Our hardness of approximation results usually apply to proof length measured either by (...) number of symbols or by number of inferences, for tree-like or dag-like proofs. We introduce the Monotone Minimum (Circuit) Satisfying Assignment problem and reduce it to the problems of approximation of the length of proofs. (shrink)

We investigate a recently devised polyhedral semantics for intermediate logics, in which formulas are interpreted in n-dimensional polyhedra. An intermediate logic is polyhedrally complete if it is complete with respect to some class of polyhedra. The first main result of this paper is a necessary and sufficient condition for the polyhedral completeness of a logic. This condition, which we call the Nerve Criterion, is expressed in terms of Alexandrov’s notion of the nerve of a poset. It affords a purely combinatorial (...) characterisation of polyhedrally complete logics. Using the Nerve Criterion we show, easily, that there are continuum many intermediate logics that are not polyhedrally complete but which have the finite model property. We also provide, at considerable combinatorial labour, a countably infinite class of logics axiomatised by the Jankov–Fine formulas of ‘starlike trees’ all of which are polyhedrally complete. The polyhedral completeness theorem for these ‘starlike logics’ is the second main result of this paper. (shrink)

New nursing researchers are faced with a smorgasbord of competing methodologies. Sometimes, they are encouraged to adopt the research paradigms beloved of their senior colleagues. This is a problem if those paradigms are no longer of contemporary methodological relevance. The aim of this paper was to provide clarity about current research paradigms. It seeks to interrogate the continuing viability of positivism as a guiding paradigm for nursing research. It does this by critically analysing the methodological literature. Five major paradigms are (...) addressed: the positivist; the interpretivist/constructivist; the transformative; the realist; and the postpositivist. Acceptance of interpretivist, transformative or realist approaches necessarily entails wholesale rejection of positivism, while acceptance of postpositivism involves its partial rejection. Postpositivism has superseded positivism as the guiding paradigm of the scientific method. The incorporation in randomized controlled trials of postpositivist assumptions indicates that even on the methodological territory that it once claimed as its own, positivism has been rendered redundant as an appropriate paradigm for contemporary nursing research.

Elementary Recursive Nonstandard Analysis, in short ERNA, is a constructive system of nonstandard analysis proposed around 1995 by Patrick Suppes and Richard Sommer, who also proved its consistency inside PRA. It is based on an earlier system developed by Rolando Chuaqui and Patrick Suppes, of which Michal Rössler and Emil Jeřábek have recently proposed a weakened version. We add a Π₁-transfer principle to ERNA and prove the consistency of the extended theory inside PRA. In this extension of ERNA a σ₁-supremum (...) principle 'up-to-infinitesimals', and some well-known calculus results for sequences are deduced. Finally, we prove that transfer is 'too strong' for finitism by reconsidering Rössler and Jeřábek's conclusions. (shrink)

This paper explores how metaphorical thinking might contribute to an aetiology of florid delusions in psychosis. We argue that this approach helps to account for the path from experience to the delusional assertion, which, though relatively straightforward for monothematic delusions like the Capgras delusion, has always been difficult to account for in florid delusions in psychosis. Our account also helps to account for double book-keeping and the relative agential inertia of the belief.

Visual number adaption is a widely accepted phenomenon. This paper advances an alternative explanation for putative cases of the phenomenon. We propose that such cases may simply reflect observers adapting to the items in perceived displays, rather than their numerical quantity. Three experiments motivate consideration of this novel proposal and call into question the evidential basis for received formulations of the number adaptation hypothesis.

The COVID-19 Law Lab platform enables quantitative representation of epidemic law and policies in a given country for multiple years, enabling governments and researchers to compare countries, and learn about the impacts and drivers of policy choices. The Law Lab initiative is designed to address the urgent need for quality legal information to support the study of how law and policy can be used to effectively manage this, and future, pandemic(s).

This paper, co-authored by undergraduate students and their instructor part of an educational psychology seminar, describes a participatory curriculum design approach for preservice teacher education that focuses on the use of the principles of second-order cybernetics to teach about teaching and learning. Using elements of an Open Source Educational Processes framework, our Spring ESEPSY2309 section created project-based collective hive minds of preservice teachers, relying on a cybernetic approach at the crossroads of Gregory Bateson and Gordon Pask's theories. The classroom community (...) used four innovative tool-mediated pillars to guide collaborative activity: 1) Live-chatting using the Reddit social media platform, 2) observation of the lives, strategies, and practices used by teachers and students in their own social networks through Soundcloud podcasting to expand their own perceptions of pedagogies and best practices that they could employ in their careers, 3) open-ended paper writing, exploring sources beyond the object language provided by the textbook through extensive dyadic conversations with the instructor, and 4) training in the use of the Alice 3 game creation tool for block programming enabling the accumulation of competence in designing classroom systems that may treat students these undergraduates would soon teach as active historical agents in learning environments, combining skills from varied subjects into transdisciplinary educational experiences. We showcase outcomes of our class projects using a narrative inquiry to describe podcast episodes, a topic network analysis to illustrate the expansive nature of Open Source writing activity, and a visual depiction of our class Alice 3 games.

Rape myth acceptance, perceived barriers, and self-efficacy were examined as predictors of likelihood to report different types of rape to law enforcement among 409 undergraduates. Participants had lower likelihood to report incapacitated compared to physically forced rape. Men had lower reporting likelihood than women for rape perpetrated by the same and opposite sex and were more likely to perceive several barriers. RMA and perceived barriers predicted a lower likelihood to report several types of rape. Among men, higher self-efficacy predicted increased (...) reporting likelihood. Targeting RMA and decreasing perceived barriers is imperative to increase college students’ likelihood to report rape to local and campus law enforcement. (shrink)

This article is devoted to the problem of interpretation and understanding of African philosophy as a phenomenon of intercultural communication. It is a question of the presence of stereotypes in perception and assessments of African philosophy: from the assertion of its interiority and non-philosophical character to the propaganda of its primacy in the whole of world philosophy as the theorized core of spiritual life. The author also indentified the significant obstacle in the study of African philosophy and understanding of its (...) status in the history of world philosophy. Also the article touched the importance of African revival, and the key factors to its revival, the idea of Afrocentrism was also been mentioned as the key solution for the African revival. In this work, ethnophilosophy is further considered as the source of the whole philosophy of Africa. Attention is also paid to the problem of misunderstanding and misinterpretation of African philosophy and culture in the framework of world or universal philosophy and science. Also in the article, issue of searching for African identity is being raised, the ideas and impacts of some African thinkers, also socio-political concepts such as Pan-Africanism, Negritude, African socialism, African humanism, Afrocentrism and others, which had a serious impact on African socio-political life were also identified. The diversity of ethnic cultures, and its roles in the black continent were mentioned, and as well, emphasis on ethical issues, religions representations and superstitions. (shrink)

The task that Hume explicitly sets himself in 3.2 of the Treatise is to identify the motive that renders just actions virtuous and constitutes justice as a virtue. But surprisingly, he never provides a clear account of what this motive is. This is the problem of the missing motive. The goal of this paper is to explain this problem and offer a novel solution. To set up my solution, I analyze a recent proposal from Geoffrey Sayre-McCord and illustrate what it (...) gets right and what it gets wrong. I develop a solution that retains the benefits of his proposal while addressing its defects. The result is a significant advancement in our understanding of Hume’s theory of justice. (shrink)

Psychiatric researchers typically assume that the modelling of psychiatric symptoms is not influenced by psychiatric categories; symptoms are modelled and then grouped into a psychiatric category. I highlight this primarily through analysing research domain criteria. RDoC’s importance makes it worth scrutinizing, and this assessment also serves as a case study with relevance for other areas of psychiatry. RDoC takes inadequacies of existing psychiatric categories as holding back causal investigation. Consequently, RDoC aims to circumnavigate existing psychiatric categories by directly investigating the (...) causal basis of symptoms. The unique methodological approach of RDoC exploits the supposed lack of influence of psychiatric categories on symptom modelling, taking psychiatric symptoms as the same regardless of which psychiatric category is employed or if no psychiatric category is employed. But this supposition is not always true. I will show how psychiatric categories can influence symptom modelling, whereby identical behaviours can be considered as different symptoms based on an individual’s psychiatric diagnosis. If the modelling of symptoms is influenced by psychiatric categories, then psychiatric categories will still play a role, a situation which RDoC researchers explicitly aim to avoid. I discuss four ways RDoC could address this issue. This issue also has important implications for factor analysis, cluster analysis, modifying psychiatric categories, and symptom based approaches.

In this enlightening book, Sam Harris argues that free will is an illusion but that this truth should not undermine morality or diminish the importance of social and political freedom; indeed, this truth can and should change the way we think about some of the most important questions in life.

This paper develops an interpretation of Hume’s accounts of the obligation and value of justice. According to my interpretation, Hume takes the obligation of justice to depend (in part) on the conventions that define the rules of justice realizing a distinctive form of value, which I call functional value. Properly understanding Hume’s accounts, I argue, requires revisionary understandings of his accounts of both the set of things susceptible to fundamental moral evaluation and his view of the nature of utility.

Inquiry aims at knowledge. Your inquiry into a question succeeds just in case you come to know the answer. However, combined with a common picture on which misleading evidence can lead knowledge to be lost, this view threatens to recommend a novel form of dogmatism. At least in some cases, individuals who know the answer to a question appear required to avoid evidence bearing on it. In this paper, we’ll aim to do two things. First, we’ll present an argument for (...) this novel form of dogmatism and show that it presents a substantive challenge. Second, we’ll consider a way those who take knowledge to be the aim of inquiry can mount a response. In the course of doing so, we’ll try to get clearer on the normative connections between inquiry, knowledge and evidence gathering. (shrink)

Cet essai cherche à faire de la complémentarité entre énergie-idée, structure et fonction, et autres couples de concepts, la base d'une nouvelle ontologie qui puisse résoudre les conflits entre les pôles de description « mental » et « physique », entre la vérité mathématique et la vérité empirique et entre la mécanique quantique et la théorie de la relativité comme formes rivales d'explication scientifique. L'auteur y plaide en faveur de la fermeture déductive de l'univers à la lumière de la relation (...) logique entre le nombre et l'alphabet . Il y présente la réalité et l'autonomie conceptuelle des idées comme une alternative au platonisme et à d'autres idéologies. Il dispose de fausses interprétations, malentendus, et objections au moyen du dialogue.Conjugacy between energy-idea, structure and function, and other concept pairs is made the basis for a new ontology which resolves the conflicts between "mental" and "physical" poles of description, between mathematical and empirical truth, and between quantum mechanics and relativity theory as rival forms of scientific explanation. The deductive closure of the universe is argued for, in light of the logical connection between number and the alphabet . The reality and the conceptual autonomy of ideas are presented as an alternative to Platonism and other ideologies. Mistaken interpretations, misunderstandings and objections are handled through the medium of dialogue. (shrink)

Hume’s account of the scope of justice, many think, is implausibly narrow, apply- ing almost exclusively to respect for property rights. Such a view would indeed be highly objectionable because it would leave out of the scope of justice altogether requirements to keep our promises, obey the law, and refrain from threats and violence (among many others). I argue that Hume’s theory of justice, properly understood, avoids this objection. And seeing how is instructive because once we understand his account correctly, (...) we can appreciate its resources for offering attractive explanations of why a number of diverse phenomena fall within the scope of justice. Overcoming this challenge is a major step- ping stone on the way to seeing Hume’s theory of justice as a genuine competitor with the other dominant theories of justice in the philosophical literature.

The distinction between perception and cognition frames countless debates in philosophy and cognitive science. But what, if anything, does this distinction actually amount to? In this introductory article, we summarize recent work on this question. We first briefly consider the possibility that a perception-cognition border should be eliminated from our scientific ontology, and then introduce and critically examine five positive approaches to marking a perception–cognition border, framed in terms of phenomenology, revisability, modularity, format, and stimulus-dependence.

The centrencephalic theory of consciousness cannot yet account for some evidence from both brain damaged and normally functioning humans that strongly implicates thalamocortical activity as essential for consciousness. Moreover, the behavioral indexes used by Merker to implicate consciousness need more development, as, besides being somewhat vague, they lead to some apparent contradictions in the attribution of consciousness.

Many philosophers have thought that our folk, or pre-reflective, view of persistence is one on which objects endure. This assumption not only plays a role in disputes about the nature of persistence itself, but is also put to use in several other areas of metaphysics, including debates about the nature of change and temporal passage. In this paper, we empirically test three broad claims. First, that most people (i.e. most non-philosophers) believe that, and it seems to them as though, objects (...) persist by enduring rather than perduring. Second, that most people have a view of change on which enduring but not perduring objects count as changing. Third, that one reason why the folk represent time as dynamical is because it seems to them, and they believe that, they endure through time. We found no evidence to support these claims. While there are certainly plenty of ‘folk’ endurantists in the population we tested, there are also plenty of ‘folk’ perdurantists. We did not find robust evidence that a majority of people believed that, or it seemed to them as though, objects endure rather than perdure. We conclude that many arguments in favour of endurantism that appeal to folk beliefs about, or experiences of, persisting objects and change rest on views about those beliefs and experiences that are empirically unsupported. There is no evidence to suggest that endurantism is the folk friendly view of persistence, and so we should stop treating it as such without argument. (shrink)

PORTER S and O’HALLORAN P. Nursing Inquiry 2012; 19: 18–28 The use and limitation of realistic evaluation as a tool for evidence‐based practice: a critical realist perspectiveIn this paper, we assess realistic evaluation’s articulation with evidence‐based practice (EBP) from the perspective of critical realism. We argue that the adoption by realistic evaluation of a realist causal ontology means that it is better placed to explain complex healthcare interventions than the traditional method used by EBP, the randomized controlled trial (RCT). However, (...) we do not conclude from this that the use of RCTs is without merit, arguing that it is possible to use both methods in combination under the rubric of realist theory. More negatively, we contend that the rejection of critical theory and utopianism by realistic evaluation in favour of the pragmatism of piecemeal social engineering means that it is vulnerable to accusations that it promotes technocratic interpretations of human problems. We conclude that, insofar as realistic evaluation adheres to the ontology of critical realism, it provides a sound contribution to EBP, but insofar as it rejects the critical turn of Bhaskar’s realism, it replicates the technocratic tendencies inherent in EBP.

The current global economic crisis is historically unprecedented in that it began when poor groups in the United States defaulted on their mortgage-payments and spread fear of 'toxic debt' through an internationalised financial system, bringing the banking system close to collapse and highlighting the very individualised nature of contemporary financial relations. The symposium explores contemporary finance and banking practices in the context of Marxist political economy seeking to develop the notion of financialisation and arguing that banks' increasing reliance on individual (...) households as a source of profits amounts to a form of financial expropriation or additional profit generated in the sphere of circulation.
