BackgroundThere is increasing need for peer reviewers as the scientific literature grows. Formal education in biostatistics and research methodology during residency training is lacking. In this pilot study, we addressed these issues by evaluating a novel method of teaching residents about biostatistics and research methodology using peer review of standardized manuscripts. We hypothesized that mentored peer review would improve resident knowledge and perception of these concepts more than non-mentored peer review, while improving review quality.MethodsA partially blinded, randomized, controlled multi-center study (...) was performed. Seventy-eight neurology residents from nine US neurology programs were randomized to receive mentoring from a local faculty member or not. Within a year, residents reviewed a baseline manuscript and four subsequent manuscripts, all with introduced errors designed to teach fundamental review concepts. In the mentored group, mentors discussed completed reviews with residents. Primary outcome measure was change in knowledge score between pre- and post-tests, measuring epidemiology and biostatistics knowledge. Secondary outcome measures included level of confidence in the use and interpretation of statistical concepts before and after intervention, and RQI score for baseline and final manuscripts.ResultsSixty-four residents (82%) completed initial review with gradual decline in completion on subsequent reviews. Change in primary outcome, the difference between pre- and post-test knowledge scores, did not differ between mentored (−8.5%) and non-mentored (−13.9%) residents (p = 0.48). Significant differences in secondary outcomes (using 5-point Likert scale, 5 = strongly agree) included mentored residents reporting enhanced understanding of research methodology (3.69 vs 2.61; p = 0.001), understanding of manuscripts (3.73 vs 2.87; p = 0.006), and application of study results to clinical practice (3.65 vs 2.78; p = 0.005) compared to non-mentored residents. There was no difference between groups in level of interest in peer review (3.00 vs 3.09; p = 0.72) or the quality of manuscript review assessed by the Review Quality Instrument (RQI) (3.25 vs 3.06; p = 0.50).ConclusionsWe used mentored peer review of standardized manuscripts to teach biostatistics and research methodology and introduce the peer review process to residents. Though knowledge level did not change, mentored residents had enhanced perception in their abilities to understand research methodology and manuscripts and apply study results to clinical practice.

This study investigated the performance of boys with psychopathic tendencies and comparison boys, aged 9 to 17 years, on two tasks believed to be sensitive to amygdala and orbitofrontal cortex func- tioning. Fifty-one boys were divided into two groups according to the Psychopathy Screening Device (PSD, P. J. Frick & R. D. Hare, in press) and presented with two tasks. The tasks were the gambling task (A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) and the Intradimensional/ (...) Extradimensional (ID/ED) shift task (R. Dias, T. W. Robbins, & A. C. Roberts, 1996). The boys with psychopathic tendencies showed impaired performance on the gambling task. However, there were no group differences on the ID/ED task either for response reversal or extradimensional set shifting. The implications of these results for models of psychopathy are discussed.

§ 1. Introduction. Perhaps the most surprising recent development in complexity theory is the discovery that the class NP can be characterized using a form of randomized proof checker that only examines a constant number of bits of the “proof” that a string is in a language [6, 5, 31, 3, 4]. More specifically, writing ∣x∣ for the length of a string x, a language L in the class NP of languages recognizable in Nondeterministic polynomial time is traditionally given by (...) a polynomial p and a polynomial-time predicate P such that a string x is in L iff there is some string y satisfying P, where ∣y∣ ≤ p. Intuitively, we can think of a string y as a possible proof that x ϵ L, with the predicate P some kind of proof checker that distinguishes good proofs from bad ones. A string x is therefore in a language L ϵ NP if there is a short proof that x ϵ L, and not in L otherwise. The surprising discovery is that the deterministic proof checker that reads the entire input and proof can be replaced by a probabilistic verifier that on input x and possible proof y, where y is presented in a certain way, flips at most O coins and reads at most a constant number of bits of x and y. Obviously, a probabilistic verifier that does not read the whole proof will sometimes make mistakes. However, the surprising and essentially non-intuitive mathematical fact is that for each language L in NP, it is possible to find a polynomial q and verifier V flipping a logarithmic number of coins and reading a constant number of bits such that, for any x ϵ L, there exists y with ∣y∣ ≤ q and with V accepting with probability 1 and, for x ∉ L, there is no y with ∣y∣ ≤ q and with V accepting with probability ≥ 1/4. This idea canalsobeextended to PSPACE [10, 9], using a game that alternates between two players instead of a proof presented by a “single player.”. (shrink)

In this essay I show that Structuralism, in order to combat the impression that it is “untenable and outmoded,” needs to be attached to a phenomenology of transcendental intersubjectivity. My argument for this conclusion is: 1) that Peter Caws is right in arguing that Structuralism needs a notion of the transcendental subject because its objects, qua intentional, presuppose such a subject; 2) the objects withwhich Structuralism is concemed are objects in the sense that Husserl speaks of objects ofthe spiritual world; (...) and, 3) the spiritual world, indeed the world in general, is constituted intersubjectively. Therefore, Structuralism needs a notion of transcendental intersubjectivity.Dans cet essai, je démontre que le structuralisme doit être rattaché à une phénoménologie de l’intersubjectivité transcendantale afin d’éviter l’impression qu’il donne d’être «intenable et démodé». J’appuie cette conclusion à l’aide des arguments suivants: 1) Peter Caws a raison d’arguer que le structuralisme a besoin d’une notion de sujet transcendantal parce que ses objets, en tant qu’intentionnels, présupposent un tel sujet; 2) les objets dont s’occupe le structuralisme sont des objets au sens oú Husserl parle d’objets du monde spirituel; et 3) le monde spirituel, enfait le monde en général, est constitué de façon intersubjective. Ainsi, le structuralisme requiert une notion d’intersubjectivité transcendantale. (shrink)

J. T. Hooker argues that at Il. 24.649 ⋯πικερτομ⋯ων must mean ‘taunting’ and, since ‘taunting’ makes no sense, that ⋯πικερτομ⋯ων must have entered ourIliadat this point from a version of theIliadslightly different from ours in which it did make sense. I wish to argue that ⋯πικερτομ⋯ων has a meaning different from ‘taunting’, which makes good sense of this, and every other, context.

A considerable increase in interest in Soviet philosophy has been observable of late in the capitalist countries. There are various reasons for this. Some seek to understand its meaning so as to define their attitudes toward it, while others find it of interest for entirely different reasons — a target of criticism.

The improvement of man, of his ideological and political, occupational, and moral qualities, is a most important condition for success in the building of communism. The socialization of the new man as a creatively active, spiritually rich, and harmoniously developed personality is a goal in our Party's program. It is becoming increasingly obvious that the process of socialization means much more than familiarizing a person with the ideological principles and norms of behavior of a citizen of developed socialist society. Socrates (...) long ago was astounded by the illogic of the man who knew what was good but did what was bad. (shrink)

In speaking of the reasons for the appearance of semantics, certain writers note the following three problems the solution of which demanded semantic analysis: 1) the problem of antinomies; 2) the problem of refining and explaining the basic concepts of formalized logic and mathematics; and 3) the problem of the complete formalization of logic.
