AbstractWe consider structural completeness in modal logics. The main result is the necessary and sufficient condition for modal logics over K4 to be hereditarily structurally complete: a modal logic λ is hereditarily structurally complete iff λ is not included in any logic from the list of twenty special tabular logics. Hence there are exactly twenty maximal structurally incomplete modal logics above K4 and they are all tabular.

The argumentative approach, the probability approach, and the story model are the three normative frameworks to reasoning with judicial evidence. The story model describes that judges reach the final conclusion by going through three different stages. The model also offered certainty principles, including evidential coverage, coherence, consistency, plausibility, and structural completeness to evaluate the stories. Different researchers have criticized the story model by pointing out that the model does not elaborate the meaning of evidential coverage and plausibility. Additionally, the story model has also been charged on the ground that it does not guide how to evaluate evidential coverage or plausibility of a story and how to select the best story when judges make more than one story. The present study demonstrates that these shortcomings may be overcome by using anchored narrative theory, causal abductive reasoning, story schemes, critical questions, and principles of inference to the best explanation.

Objectives: To assess the adherence of academic radiologists in a university center to BI-RADS lexicon (BLA) and to evaluate the structural completeness of breast MRI reports. Materials and Methods: Breast MRI reports made during 2012 in a single academic center by six readers were scored for formal completeness (FS) including recording the MRI protocol, making relevant clinical correlation, and describing background enhancement; BLA including mass rather than lesion, describing lesion outline, enhancement characteristics, and dynamic curve; and also expressing the final conclusion using BLA, resulting in a maximal total score of 8. FS and BLA were correlated with reader characteristics including breast imaging background, years of academic experience, and number of breast MRIs reported yearly. Tests used for statistical analysis were the Mann–Whitney U test and analysis of variance (ANOVA). Results: Overall BLA was 38.9%. This percentage was 60.1% and 3.7% in radiologists with and without breast imaging background, respectively (P = 0.000). Mean FS among all readers was 3.81 ± 1.75. This score was 2.54 ± 1.1 for readers without breast imaging background and 4.6 ± 1.6 for the readers regularly involved in breast imaging (P = 0.000). Conclusions: Higher degree of BLA and higher mean FS were associated with radiologists regularly involved in breast imaging. No association was found with years of academic experience or number of breast MRIs interpreted yearly.
