Let A be an infinite Δ₂⁰ set and let K be creative: we show that K≤Q A if and only if K≤Q₁ A. (Here ≤Q denotes Q-reducibility, and ≤Q₁ is the subreducibility of ≤Q obtained by requesting that Q-reducibility be provided by a computable function f such that Wf(x)∩ Wf(y)=∅, if x \not= y.) Using this result we prove that A is hyperhyperimmune if and only if no Δ⁰₂ subset B of A is s-complete, i.e., there is no Δ⁰₂ subset (...) B of A such that \overline{K}≤s B, where ≤s denotes s-reducibility, and \overline{K} denotes the complement of K. (shrink)

Modelling data in applied areas particularly in reliability engineering is a prominent research topic. Statistical models play a vital role in modelling reliability data and are useful for further decision-making policies. In this paper, we study a new class of distributions with one additional shape parameter, called a new generalized exponential-X family. Some of its properties are taken into account. The maximum likelihood approach is adopted to obtain the estimates of the model parameters. For assessing the performance of these estimators, (...) a comprehensive Monte Carlo simulation study is carried out. The usefulness of the proposed family is demonstrated by means of a real-life application representing the failure times of electronic components. The fitted results show that the new generalized exponential-X family provides a close fit to data. Finally, considering the failure times data, the Bayesian analysis and performance of Gibbs sampling are discussed. The diagnostics measures such as the Raftery–Lewis, Geweke, and Gelman–Rubin are applied to check the convergence of the algorithm. (shrink)

For a complete Heyting lattice , we define a category Etale (). We show that the category Etale () is equivalent to the category of the sheaves over , Sh(), hence also with -valued sets, see [2], [1]. The category Etale() is a generalization of the category Etale (X), see [1], where X is a topological space.

Husserl on the Ego and its Eidos (Cartesian Meditations, IV) ALFREDO FERRARIN THE THEORY OF the intentionality of consciousness is essential for Husserl's philosophy, and in particular for his mature theory of the ego. But it runs into serious difficulties when it has to account for consciousness's transcendental constitution of its own reflective experience and its relation to immanent time. This intricate knot, the inseparability of time and constitution, is most visibly displayed in Husserl's writings from the 192os up to (...) the notion of the eidos ego in the fourth Cartesian Meditation. In this paper I want to dwell on the most problematic aspects of this theory. After a few preliminary remarks about the intentionality of consciousness (sec- tion 1), I try to place the theory of the substrate of habitualities in the context of Husserl's evolution on the issue of the reflection of the ego on itself (section ~). I briefly follow the threads of Husserl's shifting position from the Logical Investi- gat/ons and Ideas I to Ideas II, the Cartesian Meditations and the Cr/s/s.

[645] 646 JOURNAL OF THE HISTORY OF PHILOSOPHY 32:4 OCTOBER 1994 some historical antecedents, in particular Aristotle, of Husserl's theory of abid- ing properties which, as far as I can see, have not been pointed out before. Husserl's Entwicklungsgeschichte on the topic of the pure ego has already been the object of important scholarly works, of which Kern's 1964 Husserl und Kant seems to me the best example. But what the secondary literature does not do is develop thematically the ambiguities of Husserl's definitions of consciousness and temporality in a unitary and comprehensive way. While I follow the lead of Berger, Broekman, Kern, Marbach,' and others, I find that their work does not sufficiently stress the difficulties at the core ofintentionality and reflective time- consciousness. Therefore, although section 2 is a necessary presupposition for drawing some critical conclusions in the final two sections, it does not exhaust my theme. After clarifying the peculiarity of the notions of essence, intuition, tran- scendental and apriori, as well as their irl:educibility to a Kantian meaning, I turn to the "de facto transcendental ego" resulting from eidetic variation (section 3) in order to introduce an examination of temporality. The difficul- ties in the twofold requirement, namely, that consciousness be the identical subject of its Erlebnisse and be synthetically unified in time, concern the unity, primacy, and mutual relation of time and consciousness in the constitution of our experience. They have been heady pointed out by Ricoeur in his commen- tary on the Cartesian Meditations. But what I want to argue in section 4, going beyond Ricoeur's text, is that the tension between temporally constituted and constitutive consciousness in the ego's reflection on its own retentions and protensions does not simply make the question of time ambiguous, but has crucial and problematic bearings on the very definition of consciousness as intentionality. In this respect... -/- . (shrink)

We give a simplified treatment of revised countable support (RCS) forcing iterations, previously considered by Shelah (see [Sh, Chap. X]). In particular we prove the fundamental theorem of semi-proper forcing, which is due to Shelah: any RCS iteration of semi-proper posets is semi-proper.

While training design choices seem amoral, they interact to determine training (in)effectiveness, potentially harming/benefiting trainees and organizations. These moral implications intensify when training is administered at scale (e.g., e-training) and focuses on social issues like sexual harassment (hereafter, SH). In fact, research on SH training shows it can elicit trainees’ gender-based biases against content messengers. We suggest that one such bias, resulting from messenger gender-occupation incongruence and influencing training effectiveness, is lowered perceptions of the messenger’s integrity. We also investigate whether (...) rich media will increase or decrease this perceived integrity penalty. Using an excerpt from real SH e-training and a sample [N = 210] consistent with the targeted training audience, we conducted a 2 × 2 × 2 relative comparison experiment (messenger gender x messenger occupation x media richness) and tested a moderated mediation model of the interactive effects of messenger gender-occupation incongruence and media richness on trainees’ perceptions of messenger integrity and training outcomes. Results suggest that trainees’ perceptions of messenger integrity decrease when the messenger’s gender is incongruent with their occupation, leading to worse outcomes in text-based training. These effects, however, are mitigated by increased media richness, providing support for media richness theory. Implications for researchers and practitioners are discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Daemonic Figures: Shakespeare and the Question of ConscienceEric SpencerDaemonic Figures: Shakespeare and the Question of Conscience, by Ned Lukacher; x & 228 pp. Ithaca: Cornell University Press, 1994, $37.50 cloth, $15.95 paper.Daemonic Figures is a specialist’s book twice over. Profiting from it requires not only considerable familiarity with Heidegger, but also unquestioning acceptance of the rhetorical conventions and critical methods of contemporary theory. Lukacher uses these conventions and (...) methods to argue that conscience, properly understood, poses uncomfortable questions about the origins of self-knowledge, and leads to a mysterious but presumably enriching encounter with the limits of our certainty. Shakespeare enters the argument as the supreme example of a poet who discovers, through sensitivity to the ambiguities of language, how to peer without flinching into the Heideggerian abyss. Although the book relies too heavily on Heidegger’s unforgiving idiom, and pauses too seldom to justify suggestive but tenuous claims, at its heart lie hard, interesting questions about what having a conscience means.Lukacher wishes to restore to the idea of conscience all its paradoxical force. As a silent inner voice carrying a moral imperative from elsewhere, conscience immediately suggests an internally divided self. And although, according to Lukacher, Christian tradition locates the source of the imperative in God, and classical tradition in natural law, conscience remains irreducibly “uncanny,” because “the most intimate site of human habitation [i.e., the self] is also the strangest of places, for it is there that the (unfamiliar) god comes to presence through the language of moral judgment that tells us that we are and that because we are what we are we should act thus” (p. 7). For Lukacher, then, the question of conscience is the question of being, a question without an answer because it involves the unthinkable idea of something prior to and beyond being. The book argues that whatever speaks to us under the name of conscience must be both within and without any categories we have to explain it.Hence “daemonic figures”: drawing on the Greek notion of a realm of daimones dwelling between the human and divine worlds, Lukacher claims that the “daemon is the cipher, the name, and the figure for the incontrovertible [End Page 240] ghostliness, the familiar strangeness, that dwells between the perceptions and reflections of consciousness and the enigmatic ground of Being itself” (p. 2), or “the medium in which we come to ourselves as precisely that which is divided from itself... from the outset” (p. 6). And because, in Lukacher’s scheme, language articulates this daemonic mediation, we must seek in literary works which explore conscience—like Hamlet and Macbeth—traces of uncanniness welling up through ostensibly coherent words. Literary value accordingly involves “giving us the words with which to bring that enigmatic lack to presence” (p. 92). Simultaneously ubiquitous and inscrutable, conscience both calls to and evades us, and literature makes its home in such paradoxical territory.It follows that Lukacher seeks in texts brief flashes of something else in the midst of what’s apparently going on, a procedure which constantly risks arbitrary idiosyncrasy. For instance, in his chapter on Hamlet, Lukacher notes that the Player’s description of Priam’s death includes a line—“and with a hideous crash / Takes prisoner Pyrrhus’ ear”—whose sequence of sounds produces a ghostly authorial signature: sh... akes... Pyr... ear. And because this “countersignature” appears fragmented, in a context of hesitation, destruction and decline, Lukacher claims it creates an allegory of the “nonrelation at the heart of self-revelation” (p. 135). That is, it (and the larger drama of Hamlet’s revenge to which it obliquely gestures) reveals that at the heart of authorship, of authorized speech, of the moral law of conscience, lies “the silent play of the letter” (p. 135), the “daemonic figure” of dissolution in the midst of self-assertion, which unsettles all authorization. Hence Hamlet’s famous difficulties—he hears the whisper of Otherness in what ought to be a straightforward moral imperative to vengeance.Lukacher justifies this procedure by noting that “Derrida’s writing, no less than that of Heidegger [and presumably Shakespeare], relies on the invention of figures and metaphors through which...

My article critically evaluates five key claims in Kerr’s interpretation of Aquinas’s De Ente et Essentia, ch. 4, proof for God. The claims are: the absolutely considered essence is a second intention, or cognitional being; à la John Wippel, the real distinction between essence and existence is known before the proof; contra David Twetten, Aristotelian form is not self-actuating and so requires actus essendi; the De Ente proof for God uses the Principle of Sufficient Reason; an infinite regress must be (...) eliminated before concluding to God. This author wonders if these questionable claims are traceable to the mindset of analytic philosophy which values precision and discreteness and so can fail to appreciate crucial paradoxes in Aquinas’s metaphysics.

IntroductionCerebral visual impairment results from damage to cerebral visual processing structures. It is the most common cause of pediatric visual impairment in developed countries and rising in prevalence in developing nations. There is currently limited understanding on how neurologic, developmental, and ophthalmic factors predict outcome for pediatric CVI.MethodA retrospective manual chart review of pediatric CVI patients seen at the tertiary pediatric hospital neurology and neuro-ophthalmology service between 2010 and 2019 was conducted. Patients were stratified into severity groups, and followed over (...) time to identify outcome predictors. Collected baseline characteristics included perinatal, genetic, developmental, and neurologic history, along with neuroimaging and fundoscopic findings on examination. Longitudinal data collected included age, seizure control, and type of therapy received. Linear mixed-effect models were used for longitudinal CVI grade outcome analysis.ResultsA total of 249 individuals spanning 779 patient visits were identified. Mean age at diagnosis was 18.8 ± 16.8 months. About 64.3% were born at term age. Perinatal history revealed hypoxic ischemic encephalopathy in 16.5%, intraventricular hemorrhage in 11.6%, and seizures in 21.7%. At presentation, 60.3% had a diagnosis of cerebral palsy and 84.7% had developmental delay. Among all subjects, 78.6% had epilepsy; 33.8% had an epileptic encephalopathy, with spasms/hypsarrhythmia being most common. Abnormal neuroimaging was present in 93.8%. Genetic anomalies were present in 26.9%. Baseline visual examination revealed no blink-to-light in 24.5%; only BTL in 34.5%, fixation/tracking in 26.5%, and optokinetic drum follow in 14.4%. Longitudinal data analysis showed that perinatal history of HIE, a positive epilepsy history, using multiple epilepsy medications, cerebral palsy, and abnormal fundoscopic findings were all negatively associated with CVI grade change over time. After controlling for significant confounders, receiving any type of therapy [early childhood intervention, physical and occupational therapy, refractive error correction or glasses] was significantly associated with longitudinal improvement in CVI grade compared to patients who did not receive any therapy, with glasses yielding the largest benefit.ConclusionThis study offers extensive insights into neurologic, developmental and ophthalmologic features in patients with moderate to severe CVI. In concordance with previous findings, aspects of perinatal history and epilepsy/seizure control may help inform severity and prognosis in the general neurology or ophthalmology clinic. Conversely, these aspects, as well as genetic and specific epilepsy traits may alert vision health care providers in the clinic to pursue visual evaluation in at-risk individuals. Longitudinal follow-up of CVI patients showed that interventional therapies demonstrated vision function improvement greater than no therapy and maturational development. (shrink)
