This study assesses the retractions of scientific articles in engineering journals indexed on the Web of Science from 1945 to 2015. The data set was built based on documents containing the keywords retracted, retraction, withdrawal, or redress. We used database exploration techniques, including Structured Query Language and analysis of variance, for data analysis. We analyzed 238 retractions published by 117 journals. The most common reason for retraction was unethical research, and higher impact factors journals tended to publish more retractions. In (...) conclusion, most of the analyzed retractions were the result of unethical research and were retracted by editors. (shrink)

In this article I make three interrelated claims about Chariton's use of ἀγαθὸς δαίμων in connection with the protagonist Chaereas, who is believed to be dead. First, that it reflects a funerary formula peculiar to inscriptions from Caria, and therefore potentially supports the author's declaration to be a native of Aphrodisias in Caria; second, that the use of this funerary formula suggests an awareness of events subsequent to the death of Nero (especially the series of false Neros), which has ramifications (...) for the novel's date, use of imperial history, and ideological thrust; and third, that numismatic evidence from Alexandria supports an association between Chaereas and Nero.

This note argues for the presence of an allusion to Ennius “Annales” 1 Sk. (Musae, quae pedibus magnum pulsatis Olympum) at Appendix Vergiliana “Dirae” 48 (undae, quae uestris pulsatis litora lymphis). This has ramifications not only for the interpretation of the poem, but also for the dating of the “Dirae”, and for the question as to whether Enn. Ann. 1 Sk. is in fact the first line of Ennius’ epic poem.

Kant taught us that there are two kinds of norms: Categorical imperatives that one ought to follow regardless of one's personal aims and circumstances, and hypothetical imperatives that direct us to employ the means towards our chosen ends. Kant's distinction separates two approaches to normative epistemology. On the one hand, we have principles of "inductive rationality", typically supported by considerations such as intuitive plausibility, conformity with exemplary practice, and internal consistency. On the other hand, we may assess rules for forming (...) belief by how well they attain the objectives that motivate inquiry; in Levi's words, "the ends of inquiry control the legitimacy of inferences" [Levi 67, p. 241]. A doctrinaire attitude would ignore one of these perspectives in favour of the other; a balanced approach is to develop both and compare [cf. Helmann 97, Sec.2]. There are three possible relationships between hypothetical and categorical imperatives for empirical inquiry. (shrink)
