    On the Strong Martin Conjecture.Masanori Itai - 1991 - Journal of Symbolic Logic 56 (3):862-875.
    We study the following conjecture. Conjecture. Let T be an ω-stable theory with continuum many countable models. Then either i) T has continuum many complete extensions in L1(T), or ii) some complete extension of T in L1 has continuum many L1-types without parameters. By Shelah's proof of Vaught's conjecture for ω-stable theories, we know that there are seven types of ω-stable theory with continuum many countable models. We show that the conjecture is true for all but one of these seven (...)

    Construction of Saturated Quasi-Minimal Structure.Masanori Itai, Akito Tsuboi & Kentaro Wakai - 2004 - Journal of Symbolic Logic 69 (1):9-22.
    The notion of quasi-minimal structures was defined by B. Zil'ber as a natural generalization of minimal structures. Inspired by his work, we study here basic model theoretic properties of quasiminimal structures. Main result is the construction of ω-saturated quasi-minimal models under ω-stability assumption.

  7. Mind the Gap: Formal Ethics Policies and Chemical Scientists’ Everyday Practices in Academia and Industry.Itai Vardi & Laurel Smith-Doerr - 2015 - Science, Technology, and Human Values 40 (2):176-198.
    Asymmetrical convergence is the increasing overlap between academic and industrial sectors, but with academia moving closer toward for-profit industrial norms than vice versa. Although this concept, developed by Kleinman and Vallas, is useful, processes of asymmetrical convergence in daily laboratory life are largely unexplored. Here, observations of three lab groups of chemical scientists in academic and industry contexts illustrate variation in interactions with ethics-related policies. Findings show more tension for academic science with business-based practices, such as the move toward greater (...)

    Separable Nonlinear Least-Squares Parameter Estimation for Complex Dynamic Systems.Itai Dattner, Harold Ship & Eberhard O. Voit - 2020 - Complexity 2020:1-11.
    Nonlinear dynamic models are widely used for characterizing processes that govern complex biological pathway systems. Over the past decade, validation and further development of these models became possible due to data collected via high-throughput experiments using methods from molecular biology. While these data are very beneficial, they are typically incomplete and noisy, which renders the inference of parameter values for complex dynamic models challenging. Fortunately, many biological systems have embedded linear mathematical features, which may be exploited, thereby improving fits and (...)

  9. Presuppositional Exhaustification.Itai Bassi, Guillermo Del Pinal & Uli Sauerland - 2021 - Semantics and Pragmatics 14:1-42.
    Grammatical theories of Scalar Implicatures make use of an exhaustivity operator exh, which asserts the conjunction of the prejacent with the negation of excludable alternatives. We present a new Grammatical theory of Scalar Implicatures according to which exh is replaced with pex, an operator that contributes its prejacent as asserted content, but the negation of scalar alternatives at a non-at-issue level of meaning. We show that by treating this non-at-issue level as a presupposition, this theory resolves a number of empirical (...)

    Ethics in public administration has been a subject of growing interest for both researchers and practitioners interested in the future of governance. This study examined the relationship between ethics and performance in local governance. We tested the effects over time of an ethics program on employees' perceptions (awareness of the code of ethics, ethical leadership, inclusion of employees in ethical decision making [EDM], ethical climate [EC], organizational commitment, and quality of work life [QWL]) and behavior (organizational citizenship behavior) in one (...)

    Mendeleev's Discovery of the Periodic Law: The Origin and the Reception. [REVIEW]Masanori Kaji - 2003 - Foundations of Chemistry 5 (3):189-214.
    This paper addresses the conceptual as well as social origins of Mendeleev’s discovery of the periodic law and its reception by the chemical community by taking account of three factors: Mendeleev’s early research and its relevance to the discovery; his concepts of chemistry, especially that of the chemical elements; and the social context of the discovery and the reception in the chemical community. Mendeleev's clear distinction between abstract elements and simple bodies was a departure from Lavoisier’s famous definition of elements (...)

    The Medical Gap: Intuition in Medicine.Itai Adler - 2022 - Medicine, Health Care and Philosophy 25 (3):361-369.
    Intuition is frequently used in medicine. Along with the use of existing medical rules, there is a separate channel that physicians rely on when making decisions: their intuition. To cope with the epistemic problem of using intuition, I use some clues from Wittgenstein's philosophy to illuminate the decision-making process in medicine. First, I point to a connection between intuition as functioning in medicine and Wittgenstein's notions of "seeing as" or noticing "aspects". Secondly, I use Wittgenstein notion of empirical regularities hardened (...)

    A Report on Small Team Clinical Ethics Consultation Programmes in Japan.M. Fukuyama, A. Asai, K. Itai & S. Bito - 2008 - Journal of Medical Ethics 34 (12):858-862.
    Clinical ethics support, including ethics consultation, has become established in the field of medical practice throughout the world. This practice has been regarded as useful, most notably in the UK and the USA, in solving ethical problems encountered by both medical practitioners and those who receive medical treatment. In Japan, however, few services are available to respond to everyday clinical ethical issues, although a variety of difficult ethical problems arise daily in the medical field: termination of life support, euthanasia and (...)

    On Perturbations of Continuous Structures.Itaï Ben Yaacov - 2008 - Journal of Mathematical Logic 8 (2):225-249.
    We give a general framework for the treatment of perturbations of types and structures in continuous logic, allowing to specify which parts of the logic may be perturbed. We prove that separable, elementarily equivalent structures which are approximately $aleph_0$-saturated up to arbitrarily small perturbations are isomorphic up to arbitrarily small perturbations. As a corollary, we obtain a Ryll-Nardzewski style characterisation of complete theories all of whose separable models are isomorphic up to arbitrarily small perturbations.

    Continuous First Order Logic for Unbounded Metric Structures.Itaï Ben Yaacov - 2008 - Journal of Mathematical Logic 8 (2):197-223.
    We present an adaptation of continuous first order logic to unbounded metric structures. This has the advantage of being closer in spirit to C. Ward Henson's logic for Banach space structures than the unit ball approach, as well as of applying in situations where the unit ball approach does not apply. We also introduce the process of single point emph{emboundment}, allowing to bring unbounded structures back into the setting of bounded continuous first order logic. Together with results from cite{BenYaacov:Perturbations} regarding (...)

    Model Theoretic Stability and Definability of Types, After A. Grothendieck.Itaï Ben Yaacov - 2014 - Bulletin of Symbolic Logic 20 (4):491-496,.
    We point out how the "Fundamental Theorem of Stability Theory", namely the equivalence between the "non order property" and definability of types, proved by Shelah in the 1970s, is in fact an immediate consequence of Grothendieck's "Criteres de compacite" from 1952. The familiar forms for the defining formulae then follow using Mazur's Lemma regarding weak convergence in Banach spaces.

    Ethical Considerations on Quadratic Voting.Ben Laurence & Itai Sher - 2017 - Public Choice 1 (172):175-192.
    This paper explores ethical issues raised by quadratic voting. We compare quadratic voting to majority voting from two ethical perspectives: the perspective of utilitarianism and that of democratic theory. From a utilitarian standpoint, the comparison is ambiguous: if voter preferences are independent of wealth, then quadratic voting out- performs majority voting, but if voter preferences are polarized by wealth, then majority voting may be superior. From the standpoint of democratic theory, we argue that assess- ments in terms of efficiency are (...)

    We investigated the key anatomical structures mediating interhemispheric integration during the perception of apparent motion across the retinal midline. Previous studies of commissurotomized patients suggest that subcortical structures mediate interhemispheric transmission but the specific regions involved remain unclear. Here, we exploit interindividual variations in the propensity of normal subjects to perceive horizontal motion, in relation to vertical motion. We characterize these differences psychophysically using a Dynamic Dot Quartet (an ambiguous stimulus that induces illusory motion). We then tested for correlations between (...)

    We investigated how the structure of the brain network relates to the stability of perceptual alternation in binocular rivalry. Historically, binocular rivalry has provided important new insights to our understandings in neuroscience. Although various relationships between the local regions of the human brain structure and perceptual switching phenomena have been shown in previous researches, the global organization of the human brain structural network relating to this phenomenon has not yet been addressed. To approach this issue, we reconstructed fiber-tract bundles using (...)

    The brain is a very complex structure. Over the past several decades, many studies have aimed to understand how various non-uniform variables relate to each other. The current study compared the whole-brain network organization and global spatial distribution of cell densities in the monkey brain. Wide comparisons between 27 graph theoretical measures and cell densities revealed that only participation coefficients (PCs) significantly correlated with cell densities. Interestingly, PCs did not show a significant correlation with spatial coordinates. Furthermore, the significance of (...)

    This article reports an interesting link between the psychophysical property of intentional control of perceptual switching and the underlying neural activities. First, we revealed that the timing of perceptual switching for a dynamical dot quartet can be controlled by the observers' intention, without eye movement. However, there is a clear limitation to this control, such that each animation frame of the stimulus must be presented for a sufficiently long time length; in other words, the frequency of the stimulus alternation must (...)

    Neuronal activities have recently been reported to exhibit power-law scaling behavior. However, it has not been demonstrated that the power-law component can play an important role in human perceptual functions. Here, we demonstrate that the power spectrum of magnetoencephalograph recordings of brain activity varies in coordination with perception of subthreshold visual stimuli. We observed that perceptual performance could be better explained by modulation of the power-law component than by modulation of the peak power in particular narrow frequency ranges. The results (...)
