Cetaceans show high cognitive abilities and strong social bonds. Their primary sensory modality to communicate and sense the environment is acoustics. Research on their echolocation and social vocalizations typically uses visual and tactile systems adapted from research on primates or birds. Such research would benefit from a purely acoustic communication system to better match their natural capabilities. We argue that a full duplex system, in which signals can flow in both directions simultaneously is essential for communication research. We designed and (...) implemented a full duplex system to acoustically interact with cetaceans in the wild, featuring digital echo-suppression. We pilot tested the system in Arctic Norway and achieved an echo suppression of 18 dB. We discuss the limiting factors and how to improve the echo suppression further. The system enabled vocal interaction with the underwater acoustic scene by allowing experimenters to listen while producing sounds. We describe our motivations, then present our pilot deployment and give examples of initial explorative attempts to vocally interact with wild orcas and humpback whales. (shrink)

Doxastic dualists acknowledge both outright beliefs and credences, and they maintain that neither state is reducible to the other. This gives rise to the ‘Bayesian Challenge’, which is to explain why we need beliefs if we have credences already. On a popular dualist response to the Bayesian Challenge, we need beliefs to simplify our reasoning. I argue that this response fails because credences perform this simplifying function at least as well as beliefs do.

This paper considers contractarianism as a method of justification. The analysis accepts the key tenets of contractarianism: expected utility maximization, unanimity as the criteria of acceptance, and social-scientific uncertainty of modelled agents. In addition to these three features, however, the analysis introduces a fourth feature: a criteria of rational belief formation, viz. Bayesian belief updating. Using a formal model, this paper identifies a decisive objection to contractarian justification. Insofar as contractarian projects approximate the Agreement Model, therefore, they fail to justify (...) their conclusions. Insofar as they fail to approximate the Agreement Model, they must explain which modelling assumption they reject. (shrink)

We examine a contribution L. Susan Stebbing made to the understanding of critical thinking and its relation to formal logic. Stebbing took expertise in formal logic to authorise logical intervention in public debate, specifically in assessing of the validity of everyday reasoning. She held, however, that formal logic is purely the study of logical form. Given the problems of ascertaining logical form in any particular instance, and that logical form does not always track informal validity, it is difficult to see (...) how she could justify her belief in logical interventionism. Her answer to this problem is the contribution we explore here. It involves the view that although the logician’s expertise is not sufficient to assess arguments made in everyday contexts on its own, it nevertheless plays a unique role in giving systematicity and direction to the critique of such arguments, in particular, in public debate.

I respond to Vaidman’s recent criticisms of my paper “A New Problem for Quantum Mechanics”.

The percentage of female entrepreneurs is far below the level of males, although it has increased over the past several years. Based on the theory of planned behavior, the purpose of this article is to specify a model in which the relationship among entrepreneurial potential, gender and entrepreneurial intention are explored, by analyzing how perceived behavioral control (PBC) and perceived entrepreneurial skills, as exogenous variables, affect expression of intention for business, and how these are mediated by their entrepreneurial motivations and (...) risk taking propensity. Control variables where also included in this model, such as necessity-driven motives for business, in order to observe whether these are an influential factor. An implementation of Structural Equation Modeling (SEM) was used to analyze data collected from 677 students. Variables within the model were compared by gender using t-Test, and all multivariate analysis were done by each one separately as well in order to better gauge their perceptions. Results showed that mean differences between males and females are not abundant, and come only from intentions, PBC and subjective norm, which are higher in males; and motives for business higher in females. Multivariate analysis shows gender differences at the mediation level and that necessity-driven motives are an influencing factor, more so in males, and it hampers the significance of subjective norm. Finally, the theoretical and practical implications of the results within the framework of entrepreneurship in Spain and future alternatives to improve the entrepreneurial potential are discussed.

Building on Nozick's invariantism about objectivity, I propose to define scientific objectivity in terms of counterfactual independence. I will argue that such a counterfactual independence account is (a) able to overcome the decisive shortcomings of Nozick's original invariantism and (b) applicable to three paradigmatic kinds of scientific objectivity (that is, objectivity as replication, objectivity as robustness, and objectivity as Mertonian universalism).

The value of resting electroencephalogram (EEG) in revealing neural constitutes of consciousness (NCC) was examined. We quantified the dynamic repertoire, duration and oscillatory type of EEG microstates in eyes-closed rest in relation to the degree of expression of clinical self-consciousness. For NCC a model was suggested that contrasted normal, severely disturbed state of consciousness and state without consciousness. Patients with disorders of consciousness were used. Results suggested that the repertoire, duration and oscillatory type of EEG microstates in resting condition quantitatively (...) related to the level of consciousness expression in brain-damaged patients and healthy-conscious subjects. Specifically, results demonstrated that (a) decreased number of EEG microstate types was associated with altered states of consciousness, (b) unawareness was associated with the lack of diversity in EEG alpha-rhythmic microstates, and (c) the probability for the occurrence and duration of delta-, theta- and slow-alpha-rhythmic microstates were associated with unawareness, whereas the probability for the occurrence and duration of fast-alpha-rhythmic microstates were associated with consciousness. In conclusion, resting EEG has a potential value in revealing NCC. This work may have implications for clinical care and medical–legal decisions in patients with disorders of consciousness. (shrink)

Maybe you only have 1000 units of some resource, but 10,000 people need the resource or would benefit from it. One question: why do you control the resource? Leave that aside for now. A second question: how should you allocate the resource? If you are a decision-maker in a health system, and if the resource has to do with medicine or public health, we are in the world of the ethics of scarce resource allocation decisions in healthcare. Munthe et al (...) 1 note that the ‘operational norms that guide actual decision making in this area tend to be similar across health systems’ and include principles concerning need, prognosis, equal treatment and cost-effectiveness. Even with just these principles, there are hard questions of how they ought to be specified, operationalised and balanced against each other when they conflict. They do not focus on this. Instead, they identify a concern: paying attention only to these principles in making allocation decisions may lead decision-makers to miss ‘negative dynamics’ that result from their decisions. They aim to rectify this by suggesting a ‘sustainability’ principle that would sit alongside these other ethical principles, serving as a side-constraint that rules out certain allocation choices or as a distinct reason to be weighed in the decision-making calculus (or a reason to save or insure against negative dynamics). I agree that the downstream effects of our allocation decisions matter, …. (shrink)

ObjectiveCo-morbid insomnia and sleep apnea is a common and debilitating condition that is more difficult to treat compared to insomnia or sleep apnea-alone. Emerging evidence suggests that cognitive behavioral therapy for insomnia is effective in patients with COMISA, however, those with more severe sleep apnea and evidence of greater objective sleep disturbance may be less responsive to CBTi. Polysomnographic sleep study data has been used to predict treatment response to CBTi in patients with insomnia-alone, but not in patients with COMISA. (...) We used randomized controlled trial data to investigate polysomnographic predictors of insomnia improvement following CBTi, versus control in participants with COMISA.MethodsOne hundred and forty five participants with insomnia and sleep apnea [apnea-hypopnea index ≥ 15] were randomized to CBTi or no-treatment control. Mixed models were used to investigate the effect of pre-treatment AHI, sleep duration, and other traditional, and novel [quantitative electroencephalography ] polysomnographic predictors of between-group changes in Insomnia Severity Index scores from pre-treatment to post-treatment.ResultsCompared to control, CBTi was associated with greater ISI improvement among participants with; higher AHI, less wake after sleep onset, and less N3 sleep. No quantitative electroencephalographic, or other traditional polysomnographic variables predicted between-group ISI change.DiscussionAmong participants with COMISA, higher OSA severity predicted a greater treatment-response to CBTi, versus control. People with COMISA should be treated with CBTi, which is effective even in the presence of severe OSA and objective sleep disturbance. (shrink)

Dispositions are related to conditionals. Typically a fragile glass will break if struck with force. But possession of the disposition does not entail the corresponding simple (subjunctive or counterfactual) conditional. The phenomena of finks and antidotes show that an object may possess the disposition without the conditional being true. Finks and antidotes may be thought of as exceptions to the straightforward relation between disposition and conditional. The existence of these phenomena are easy to demonstrate at the macro-level. But do they (...) exist at the fundamental level also? While fundamental finkish dispositions may be excluded fairly straightforwardly, the existence of fundamental antidotes is more open. Nonetheless I conclude that the phenomenon is likely to be less widespread than at the macro level and that fundamental antidotes may be eliminable. According to the dispositional essentialist, the laws of nature can be explained by taking natural properties to be essentially dispositional. This account can be extended to show that the existence of finks and antidotes explains ceteris paribus laws. Consequently the existence or otherwise of fundamental finks and antidotes sheds some light on the question of whether fundamental laws may also be ceteris paribus laws. (shrink)

In simplified form, the argument that I am defending holds that the incompatibility of our freedom with determinism follows from the conjunction of (1) a plausible supervenience claim which says that whether a human agent is free depends only on what happens during the agent’s life and (2) a freedom-cancellation principle of Richard Gale which says that an agent is not free if all of her actions are intentionally brought about by another agent. Improved versions of (1) and (2) are (...) also considered. (shrink)

ZUSAMMENFASSUNGIm Diskurs zum Theodizeeproblem beschäftigen sich die einzelnen Autoren mit sehr unterschiedlichen Ausgangsfragen, und zwar meist ohne diese Tatsache zu reflektieren. Wenn man jedoch ernst nimmt, dass »das Theodizeeproblem« einen Sammelbegriff für sehr unterschiedliche Fragen darstellt, setzt eine sinnvolle Bearbeitung des Theodizeeproblems eine bewusste Benennung der genauen Ausgangsfrage und idealerweise eine sachliche Begründung für die Wahl eben dieser Frage voraus. Davon, ob die Ausgangsfrage im Horizont des Glaubens formuliert wird oder nicht, in existenzieller oder in abstrahierender Perspektive, mit Gott als (...) Adressat oder nicht, anhand eines schöpfungstheologischen, kreuzestheologischen oder eschatologischen Zugangs, unter Zugrundelegung eines traditionell-theistischen oder eines nicht traditionell-theistischen Gottesbegriffs, agnostisch oder atheistisch, logisch oder empirisch, hängt es ab, ob es eine Antwort gibt, welche Antwortmöglichkeiten in den Blick kommen können und welche nicht, welche Bedürfnisse des Fragenden befriedigt werden und welche nicht, kurz: was von der weiteren Problembearbeitung erwartet werden kann und was nicht.SUMMARYIn the discourse on theodicy, individual authors deal with very different initial questions and for the most part fail to reflect upon this very fact. However, if one does recognize the importance of understanding THE problem of evil as an umbrella term for quite distinct issues, a proper treatment of theodicy implies precisely specifying the initial question and, ideally, a factual justification for the choice of this question. Whether the initial question is phrased in the horizon of faith, in an existential or abstract perspective, whether it directly adresses God, whether it is approached by means of creation theology, a theology of the cross or eschatological theology, whether it is based on a traditional theistical idea of god, agnostic or atheistic, logical or empirical, ultimately determines the actual existence of an answer, which possible answers can be brought to the questioner's attention and which of his or her needs can be satisfied in this regard; in short, what can be expected from the treatment of the problem and what cannot.

In this paper we define n+1-valued matrix logic Kn+1 whose class of tautologies is non-empty iff n is a prime number. This result amounts to a new definition of a prime number. We prove that if n is prime, then the functional properties of Kn+1 are the same as those of ukasiewicz's n +1-valued matrix logic n+1. In an indirect way, the proof we provide reflects the complexity of the distribution of prime numbers in the natural series. Further, we introduce (...) a generalization K n+1 * of Kn+1 such that the set of tautologies of Kn+1 is not empty iff n is of the form p , where p is prime and is natural. Also in this case we prove the equivalence of functional properties of the introduced logic and those of n+1. In the concluding part, we discuss briefly a partition of the natural series into equivalence classes such that each class contains exactly one prime number. We conjecture that for each prime number the corresponding equivalence class is finite. (shrink)

The authors consider reflexive games that describe the interaction of subjects making decisions based on an awareness structure, i.e., a hierarchy of beliefs about essential parameters, beliefs about beliefs, and so on. It was shown that the language of graphs of reflexive games represents a convenient uniform description method for reflexion effects in bélles-léttres.

I present an argument that encapsulates the view that theory is underdetermined by evidence. I show that if we accept Williamson's equation of evidence and knowledge, then this argument is question-begging. I examine ways of defenders of underdetermination may avoid this criticism. I also relate this argument and my critique to van Fraassen's constructive empiricism.

Determinism is a doctrine or assumption best defined in the realm of the natural sciences. In this paper I explain in detail the four senses of determinism, from the most fundamental metaphysical sense, to the most complex epistemic (predictive) sense. I take as a starting point the analysis of determinism offered by Stephen Kellert. Each of these senses is then expounded and commented with a view to explore some of the implications of each of them in theoretical physics. The most (...) important of my tasks in this paper is to differentiate between the metaphysical and epistemic consequences of the deterministic assumption. My objective is to show that determinism as an ontological tenet is capable of withstanding criticism, even though predictive determinism is likely to be false. (shrink)

Excerpt from The Ethics of the Fathers The Discourses in this volume were originally preached in German and created a furore at the time of their delivery. They were the author's first efforts in the American Jewish pulpit, which he so conspicuously adorned. Heard by very large audiences, they were eagerly read and discussed throughout the length and breadth of the land when they appeared, week by week, in the columns of The American Hebrew, in hastily prepared translation by his (...) friend Max Cohen, the Librarian of the then Maimonides Free Library. They were afterwards published in book form. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

The fundamental Hennigian principle, grouping solely on synapomorphy, is seldom used in modern phylogenetics. In the submitted paper, we apply this principle in reanalyzing five datasets comprising 197 complete plastid genomes (plastomes). We focused on the latter because plastome-based DNA sequence data gained dramatic popularity in molecular systematics during the last decade. We show that pattern-cladistic analyses based on complete plastid genome sequences can successfully resolve affinities between plant taxa, simultaneously simplifying both the genomic and analytical frameworks of phylogenetic studies. (...) We developed “Matrix to Newick” (M2N), a program to represent the standard molecular alignment of plastid genomes in the form of trees or relationships directly. Thus, massive plastome-based DNA sequence data can be successfully represented in a relational form rather than as a standard molecular alignment. Application of methods of median supertree construction (the Average Consensus method has been used as an example in this study) or Maximum Parsimony analysis to relational representations of plastome sequence data may help systematist to avoid the complicated assumption-based frameworks of Maximum Likelihood or Bayesian phylogenetics that are most used today in massive plastid sequence data analyses. We also found that significant amounts of pure genomic information that typically accommodate the majority of current plastid phylogenomic studies can be effectively dropped by systematists if they focus on the pattern-cladistics or relational analyses of plastome-based molecular data. The proposed pattern-cladistic approach is a powerful and straightforward heuristic alternative to modern plastome-based phylogenetics. (shrink)

The paper presents the second part of the study of “sponsored goods” in the cultural sector. It describes economic activities of theaters, concert organizations and museums in three dimensional index space coordinate axes being the lag of labor productivity, faster growth of salaries and tickets prices in relation to the corresponding macroeconomic indices. The methodology of constructing such indexes and statistical data used for this purpose are described in the first article published under the title “Symptoms and consequences of Baumol’s (...) cost disease in cultural sector: an econometric study of “sponsored goods”. The aim of the present article is to construct and analyse econometric model of cost disease based on statistical data on activities of Russian theaters, concert organizations and museums for the period of 1994-2010. The regression analysis based on structural model that reflects theoretically predictable links was chosen as a method of study. Such links include first, influence on cost growth of lag of labour productivity in arts organisations and parallel trend in salaries. Second, dependence of increase of income of such organizations on dynamics of labour productivity and ticket prices, third, balanced equation - product of equilibrium conditions for sponsored goods that describes the interrelation between costs of production, prices and budget subsidies. The calculations made it possible to construct basic and modified econometric models that establish statistical correlations between income deficit and three regressors, namely indexes of labour productivity, salaries and ticket prices. As a result of this model the article presents projections of regression relation of income deficit on «expenditures plane», «income plane» and «economic results plane». Theequations derived allow to conclude that there is a statistically significant income deficit negative elasticity by labour productivity index, positive elasticity by salaries index and ticket price index, as well as rising dynamics of Russian performing arts organization income deficit and its compensation in the nearest future.

This contribution seeks to clarify the status of Ereignis and Dasein in the Beiträge zur Philosophie and to question, in particular, the relationship between these two concepts. The angle that will be preferred here is that of the discussion with transcendentalism. The author defends the thesis that there is an alteration in the meaning of “Dasein” between Sein und Zeit and the Beiträge zur Philosophie, having repercussions on the relationship between “Seyn” and “Da-sein”. At the very heart of this new (...) meaning of Da-sein in the Beiträge stands the conception of an “out-standing standing-within” that must be analyzed in detail. (shrink)
