Mistakes during criminal investigations are costly, leading to wrongful convictions, so it is helpful to employ rigorous analytic methods to help mitigate errors and biases. This paper introduces a new method to help make sense of a set of information, allowing thought processes to be externalised in a systematic and transparent manner. While this method is presented in a criminal investigation context, it can be applied to any situation where analysis of several hypotheses and evidence is required. Open source software (...) was created and used to test the method empirically. A simulated criminal investigation was carried out by seventy-five trainee investigators, the results showed better conclusions were reached when using the method. (shrink)

What the causes of aging are and which factors define lifespan are key questions in the understanding of aging. Here, it is argued that cellular life involves (i) inevitable accumulation of damage resulting from imperfectness and heterogeneity of every cellular process, and (ii) dilution of damage when cells divide. While severe damage is cleared by protective systems, milder damage can only be diluted. This is due to the high cost of accuracy, the greater number of damage forms compared to protective (...) systems, and the constraints on cellular life inherited from the prokaryotic world. This strategy also applies to cancer cells, which are particularly dependent on damage dilution. Imposing restriction on cell division necessarily leads to aging. Interventions that extend lifespan act through metabolic reprogramming, thereby changing both damage composition and the rate of damage accumulation. Thus, heterogeneity leading to myriad mild damage forms represents the cause of aging, whereas the processes that affect the damage landscape and damage accumulation are lifespan regulators.

Traxler, Pickering, and Clifton found that ambiguous sentences are read faster than their unambiguous counterparts. This so-called ambiguity advantage has presented a major challenge to classical theories of human sentence comprehension because its most prominent explanation, in the form of the unrestricted race model, assumes that parsing is non-deterministic. Recently, Swets, Desmet, Clifton, and Ferreira have challenged the URM. They argue that readers strategically underspecify the representation of ambiguous sentences to save time, unless disambiguation is required by task demands. When (...) disambiguation is required, however, readers assign sentences full structure—and Swets et al. provide experimental evidence to this end. On the basis of their findings, they argue against the URM and in favor of a model of task-dependent sentence comprehension. We show through simulations that the Swets et al. data do not constitute evidence for task-dependent parsing because they can be explained by the URM. However, we provide decisive evidence from a German self-paced reading study consistent with Swets et al.'s general claim about task-dependent parsing. Specifically, we show that under certain conditions, ambiguous sentences can be read more slowly than their unambiguous counterparts, suggesting that the parser may create several parses, when required. Finally, we present the first quantitative model of task-driven disambiguation that subsumes the URM, and we show that it can explain both Swets et al.'s results and our findings. (shrink)

Modal logic S5 is commonly viewed as an epistemic logic that captures the most basic properties of knowledge. Kripke proved a completeness theorem for the first-order modal logic S5 with respect to a possible worlds semantics. A multiagent version of the propositional S5 as well as a version of the propositional S5 that describes properties of distributed knowledge in multiagent systems has also been previously studied. This article proposes a version of S5-like epistemic logic of distributed knowledge with quantifiers ranging (...) over the set of agents, and proves its soundness and completeness with respect to a Kripke semantics.

We give an exponential lower bound on the number of proof-lines in intuitionistic propositional logic, IL, axiomatised in the usual Frege-style fashion; i.e., we give an example of IL-tautologies A1,A2,… s.t. every IL-proof of Ai must have a number of proof-lines exponential in terms of the size of Ai. We show that the results do not apply to the system of classical logic and we obtain an exponential speed-up between classical and intuitionistic logic.

One of the most prevalent rationales for public healthcare policies is a human right to healthcare. Governments are the typical duty-bearers, but they differ vastly in their capacity to help those vulnerable to serious health problems and those with severe disabilities. A right to healthcare is out of the reach of many developing economies that struggle to provide the most basic services to their citizens. If human rights to provision of such goods exist, then governments would be violating rights without (...) doing anything wrong. I argue that such variable ability to provide healthcare depends not only on financial resources, but on institutional capacity, and that the latter represents a more fundamental challenge to the existence of a human right to healthcare than previously recognized. This challenge does not imply that government has no obligations to protect and improve the health of their citizens, but that it is best to think of such obligations as generated by conventional rights, namely rights arising from local legal and social conventions, which require governments to pursue health-related moral goals such as reducing suffering, closing opportunity gaps for the disadvantaged, and preventing the spread of contagious diseases. We need not think of such moral goals in terms of human rights. (shrink)

2 Popper's Logical Definition of Verisimilitude. 3 Popper's Probabilistic Definition of Verisimilitude. 4 Conclusion.

It is well known that the manner in which a definitely descriptive term contributes to the meaning of a sentence depends on the place the term occupies in the sentence. A distinction is accordingly drawn between ordinary contexts and contexts variously termed non-referential, intensional, oblique, or opaque. The aim of the present article is to offer a general account of the phenomenon, based on transparent intensional logic. It turns out that on this approach there is no need to say (as (...) Frege does) that descriptive terms are referentially ambiguous or to deny (as Russell does) that descriptive terms represent self-contained units of meaning. There is also no need to tolerate (as Montague does) exceptions to the Principle of Functionality. The notion of an ordinary (i.e., non-intensional) context is explicated exclusively in terms of logical structure and it is argued that two aspects of ordinariness (termed hospitality and exposure) must be distinguished.

In this paper we argue that Aristotle operates with a particular theoretical model in his explanation of animal locomotion, what we call the ‘centralized incoming and outgoing motions’ model. We show how the model accommodates more complex cases of animal motion and how it allows Aristotle to preserve the intuition that animals are self-movers, without jeopardizing his arguments for the eternity of motion and the necessary existence of one eternal unmoved mover in Physics VIII. The CIOM model helps to elucidate (...) Aristotle’s two central yet problematic claims, namely that the soul is the efficient cause of animal motion and that it is the internal supporting-point necessary for animal motion. Moreover, the CIOM model helps us to explain the difference between voluntary, involuntary and non-voluntary motions, and to square Aristotle’s cardiocentrism with his hylomorphism, but also, more generally, it provides an interesting way of thinking about the place of intentionality in the causal structure of the world.

Roman Catholic and Eastern Orthodox theologians claim that the unique event of Christ’s sacrifice on Calvary is present in Eucharistic liturgies. A popular explanatory strategy for this miraculous presence suggests that due to its supernatural character the Eucharist “conquers time,” transcends its boundaries, and allows for temporal coincidence of two chronologically distant events. I discuss the four main approaches within this strategy that can be discovered in contemporary theological writings. The first approach implies a time travel of the Calvary event. (...) The second suggests the time travel of Eucharistic participants. The third eliminates the chronological distance by relocating one of the events into a timeless reality. The fourth assumes multilocation of the event across time. I argue that each of these approaches is untenable on philosophical or theological grounds. (shrink)

Despite relative neglect in the literature, Kant’s published and unpublished writings in theoretical philosophy reveal a sustained and at times ambivalent effort to come to terms with the problem of miracles. Because they entail a form of supernatural causation that undermines the law-governedness of the order of nature, miracles pose a significant problem for Kant’s metaphysics. I explore in detail Kant’s account of miracles in conjunction with the relevant aspects of his metaphysics of nature in order to establish in what (...) sense miracles are possible, and how they fit into Kant’s architectonic more generally.

The article offers a rigorous truth condition for subjunctively conditional statements. The theory is framed in the system of transparent intensional logic and takes connections (especially the cause-Effect relation) as basic. Counterexamples are given to rival theories based on the notion of world similarity.

_ Source: _Volume 48, Issue 2, pp 265 - 285 This article examines the development of Heidegger’s thought directly following _Being and Time_, a period that is significant both in its own right and in its capacity to shed light on the problems driving Heidegger’s later works. I assess Crowell’s thesis that Heidegger’s aim was to develop a metontology along the lines of a pre-critical _metaphysica specialis_ based on a reassessment of Kant’s transcendental dialectic. I show that such a reading (...) misrepresents the nature of Heidegger’s project in this period and argue that Heidegger was instead attempting to develop a distinctively critical metaphysics in a post-Kantian vein.

A critical comment to Horwich's deflationary theory of meaning: the deflationary view ignores the fact that the way the subexpressions of an expression are combined is language dependent unlike meaning, which is in a sense 'international'; the link between the grammatical structure and the respective construction is not as direct and simple as it would follow from Horwich's conception.

There is probably only one information system in living nature — the macromolecular system including DNA, RNA and protein. Its unity for the genetic and nervous activity can be followed in the storage of information (heredity, memory) and in its processing (recombination and selection of both genetic and mental information). According to the hypothesis of the code of nerve impulses, nucleotide triplets of the nucleus, or more likely amino acids of the surface protein of the impulse generating area of a (...) neuron, generate a limited variety of interspike intervals so that each amino acid corresponds to a certain interspike interval and this particular interval initiates by means of a specific neurotransmitter, the synthesis of the same amino acid (or nucleotide triplet) in the postsynaptic neuron. Thus, a series of impulses produces in the postsynaptic neuron a sequence of amino acids in a form of a polypeptide identical to the polypeptide of the presynaptic neuron. (shrink)

This essay sheds additional light on the biographies and fates of Ayn Rand’s closest relatives in the Soviet Union and abroad after young Alissa Rosenbaum left the “country of workers and peasants” in 1926 for the pursuit of a new life in the United States. Previously unknown facets of her relatives’ lives were intertwined with the complex and often tragic historical events of the first half of the twentieth century. Among these relatives are victims of the German blockade of Leningrad, (...) a music teacher, a European bacteriologist, a doctor who was twice a refugee, and a Soviet Medical Service Corps officer.

The article analyzes the concept of serendipity as a property and state of personality. The approach chosen by the author is aesthetic; the problem is covered from the perspectives of pedagogy and didactics. The object of the study is the phenomenon of "intuitive serendipity", the subject is the methods of creativity development. Comparison of different types of thinking (inductive, deductive, paradoxical) allowed us to make a number of generalizing judgments. In particular, the superiority of "paradox logic" over formal logic and (...) the role of intuition and "sense of truth" in the process of cognition. On the basis of the conclusions it is proposed to discuss the author's hypothesis of the trigger principle of learning based on cultivating a craving for knowledge, ideological immunity and the ability to independently search for and analyze information, as well as to implement it in the creative process. В статье приводится анализ понятия серендипности как свойства и состояния личности. Выбранный автором подход — эстетический; освещение проблемы в ракурсах педагогики и дидактики. Объект исследования — феномен "интуитивной прозорливости", предмет — методики развития творческого потенциала. Сравнение различных типов мышления (индуктивное, дедуктивное, парадоксальное) позволило выйти на ряд суждений обобщающего характера. В частности — о превосходстве "логики парадокса" над логикой формальной и о роли интуиции и "чувства истины" в процессе познания. На основании выводов предлагается обсудить авторскую гипотезу триггерного принципа обучения, основанного на культивировании тяги к знаниям, идеологического иммунитета и способности самостоятельно искать и анализировать информацию, а также реализовывать ее в творческом процессе.

We prove an exponential lower bound on the length of cutting plane proofs. The proof uses an extension of a lower bound for monotone circuits to circuits which compute with real numbers and use nondecreasing functions as gates. The latter result is of independent interest, since, in particular, it implies an exponential lower bound for some arithmetic circuits.

Two different types of functional dependencies are compared: dependencies that are functional due to the laws of nature and dependencies that are functional if all involved agents behave rationally. The first type of dependencies was axiomatized by Armstrong. This article gives a formal definition of the second type of functional dependencies in terms of strategic games and describes a sound and complete axiomatization of their properties. The axiomatization is significantly different from the Armstrong’s axioms.

Motivated by the problem of finding finite versions of classical incompleteness theorems, we present some conjectures that go beyond NP ≠ coNP. These conjectures formally connect computational complexity with the difficulty of proving some sentences, which means that high computational complexity of a problem associated with a sentence implies that the sentence is not provable in a weak theory, or requires a long proof. Another reason for putting forward these conjectures is that some results in proof complexity seem to be (...) special cases of such general statements and we want to formalize and fully understand these statements. Roughly speaking, we are trying to connect syntactic complexity, by which we mean the complexity of sentences and strengths of the theories in which they are provable, with the semantic concept of complexity of the computational problems represented by these sentences. -/- We have introduced the most fundamental conjectures in our earlier works. Our aim in this article is to present them in a more systematic way, along with several new conjectures, and prove new connections between them and some other statements studied before. (shrink)
