Japanese Teachers at the Royal School of Commerce (1873-1923)

Only five years after the Royal Superior School of Commerce (the present Ca' Foscari University) was founded in 1868, the School introduced, for the first time in Italy, Japanese language courses taught by native speakers. The classes started in 1873 and continued until 1888, and were again part of the curriculum from 1909 to 1923. In those years a little number of very active Japanese teachers (interprets, linguists, sculptors and painters) contributed to shaping the education in Japanese of Italian students, who in turn went on to direct Japanese instruction in Italy. Their guiding spirit was Guglielmo Berchet, a tireless promoter of Italo-Japanese relations

Hansen\u27s disease (leprosy) in Japan, 1947-2020: an epidemiologic study during the declining phase to elimination

Objectives: Leprosy, or Hansen’s disease was a major public health problem in Japan in the early 20th century. Today, the number of new cases has decreased significantly. We aimed to investigate the trends of leprosy in Japan over the past 73 years and the challenges faced in recent years. Methods: We assessed the data on newly registered cases of leprosy from 1947 to 2020. Results: A total of 10,796 newly registered cases of leprosy were reported during the study period, of which 7573 were registered in mainland Japan, 2962 in Okinawa, and 250 were of foreign origin. Most autochthonous cases were born before 1950 in mainland Japan and before 1975 in Okinawa. The number of nonautochthonous cases surpassed that of autochthonous cases in 1992. Nonautochthonous cases orig- inated from 26 countries, particularly Brazil and the Philippines. Three cases of antimicrobial resistance have been detected among nonautochthonous cases since 2004. Conclusion: Our data suggest that ongoing transmission of leprosy likely ceased in the 1940s in mainland Japan and in the 1970s in Okinawa. With the recent rise of nonautochthonous cases with globalization, continuous surveillance and effort s to maint ain leprosy services within the country are necessary even after reaching the state of elimination

ARTADE2DB: Improved Statistical Inferences for Arabidopsis Gene Functions and Structure Predictions by Dynamic Structure-Based Dynamic Expression (DSDE) Analyses

Recent advances in technologies for observing high-resolution genomic activities, such as whole-genome tiling arrays and high-throughput sequencers, provide detailed information for understanding genome functions. However, the functions of 50% of known Arabidopsis thaliana genes remain unknown or are annotated only on the basis of static analyses such as protein motifs or similarities. In this paper, we describe dynamic structure-based dynamic expression (DSDE) analysis, which sequentially predicts both structural and functional features of transcripts. We show that DSDE analysis inferred gene functions 12% more precisely than static structure-based dynamic expression (SSDE) analysis or conventional co-expression analysis based on previously determined gene structures of A. thaliana. This result suggests that more precise structural information than the fixed conventional annotated structures is crucial for co-expression analysis in systems biology of transcriptional regulation and dynamics. Our DSDE method, ARabidopsis Tiling-Array-based Detection of Exons version 2 and over-representation analysis (ARTADE2-ORA), precisely predicts each gene structure by combining two statistical analyses: a probe-wise co-expression analysis of multiple transcriptome measurements and a Markov model analysis of genome sequences. ARTADE2-ORA successfully identified the true functions of about 90% of functionally annotated genes, inferred the functions of 98% of functionally unknown genes and predicted 1,489 new gene structures and functions. We developed a database ARTADE2DB that integrates not only the information predicted by ARTADE2-ORA but also annotations and other functional information, such as phenotypes and literature citations, and is expected to contribute to the study of the functional genomics of A. thaliana.

Vittorio Pica e la critica sull’arte giapponese in Italia

Vittorio Pica, a Neapolitan critic of literature and art, was the first to introduce Japanese art in Italy, where, unlikely in France, Britain and the United States, it was not well known. His interest had its origin in an enthusiastic admiration for Edmond De Goncourt, the famous japonisant and author of Outamaro, le peintre des maisons vertes (1891). Under Goncourt’s strong influence, Pica wrote a review of Goncourt’s book, and later on, in 1894, produced a book of his own on Japanese art, L’arte dell’Estremo Oriente. In this work, Pica translated almost literary from French critics, especially from Goncourt, Louis Gonse and Theodore Duret. L’arte dell’Estremo Oriente made him the key-person for that field of study in Italy, remaining the basis of his future work. His monopoly, however, came to an and when Japanese art was exhibited at the second Biennale of Venice in 1897: other critics could see the exhibited works, and especially Ugo Ojetti, Pica’s rival, showed an accurate knowledge of the subject matter, which he had probably obtained from English and French sources. Ojetti pointed out also some Pica’s and other author’s errors. The Venice exhibition was for Pica an occasion for observing directly the contemporary art of Japan. In 1905 the Chiossone Museum of Oriental Art was opened in Genoa by Alfredo Luxoro after long preparations, and Pica presented it to public on the magazine Emporium. His criticism seems to have entered a different phase on that very occasion. As a conclusion, it can be said that Italian art critics like Pica could not rely on native Japanese unlike the critics in Paris, where there was Tadamasa Hayashi, and that, more generally, Italy had remained behind European avant-garde. In addition, Pica was not such a zealous art collector like other critics, and did not own significant collection of books and engravings. For this reason his criticism of Japanese art was not fully convincing, and he was responsible for the limits within which Japanese art was received in Italy

Heterogeneous component analysis

In bioinformatics it is often desirable to combine data from various measurement sources and thus structured feature vectors are to be analyzed that possess different intrinsic blocking characteristics (e.g., different patterns of missing values, observation noise levels, effective intrinsic dimensionalities). We propose a new machine learning tool, heterogeneous component analysis (HCA), for feature extraction in order to better understand the factors that underlie such complex structured heterogeneous data. HCA is a linear block-wise sparse Bayesian PCA based not only on a probabilistic model with block-wise residual variance terms but also on a Bayesian treatment of a block-wise sparse factor-loading matrix. We study various algorithms that implement our HCA concept extracting sparse heterogeneous structure by obtaining common components for the blocks and specific components within each block. Simulations on toy and bioinformatics data underline the usefulness of the proposed structured matrix factorization concept.
