How children interpret disjunction under negation in Dutch, French, Hungarian and Italian: a crosslinguistic comparison
No full textIn English, a sentence like “The cat didn’t eat the carrot or the pepper” typically receives a “neither” interpretation; in Japanese it receives a “not this or not that” interpretation. These two interpretations are in a subset/superset relation, such that the “neither” interpretation (strong reading) asymmetrically entails the “not this or not that” interpretation (weak reading). This asymmetrical entailment raises a learnability problem. According to the Semantic Subset Principle, all language learners, regardless of the language they are exposed to, start by assigning the strong reading, since this interpretation makes such sentences true in the narrowest range of circumstances.). If the “neither” interpretation is children’s initial hypothesis, then children acquiring a superset language will be able to revise their initial hypothesis on the basis of positive evidence.
The aim of the present study is to test an additional account proposed by Pagliarini, Crain, Guasti (2018) as a possible explanation for the earlier convergence to the adult grammar by Italian children. The hypothesis tested here is that the presence of a lexical form such as recursive né that unambiguously conveys a “neither” meaning, would lead children to converge earlier to the adult grammar due to a blocking e!ect of the recursive né form in the inventory of negated disjunction forms in a language. We compared data from Italian (taken from Pagliarini, Crain, Guasti, 2018), French, Hungarian and Dutch. Dutch was tested as baseline language. French and Hungarian have – similarly to Italian – a lexical form that unambiguously expresses the “neither” interpretation (ni ni and sem sem, respectively). Our results did not support this hypothesis however, and are discussed in the light of language-speci"c particularities of the syntax and semantics of
negation
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
[Review of] William C. Crain. Theories of Development: Concepts and Applications
No full textTheories of Development: Concepts and Applications provides an excellent overview of developmental thinking throughout history and across several theoretical disciplines from Rousseau, the father of the developmental tradition, and Locke, the father of environmentalism, to the behaviorists and psycholinguists, Skinner and Chomsky. Crain then extends his coverage to the humanistic movement of Maslow and others. As Crain traces developmental theory, he draws parallels between early developmentalists and the modern humanists, suggesting that learning theorists and other environmentalists, by placing their focus on controlling and shaping behavior, provide an orientation that is too one sided. Modern humanists, suggests Crain, seek environments which allow the natural and spontaneous growth forces of human beings to unfold and which do not force behaviors into predetermined molds. The volume provides a broad survey of developmental psychological thought, including, in addition to the above, the social learning theory of Bandura, Jungian, Freudian, and Eriksonian theory, Schachtel\u27s work on childhood experiences, Werner\u27s organismic and comparative theory, Gessell\u27s work, Kohlberg\u27s work, the ethological theories and finally, the cognitive theories of Piaget

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.
