Comparative Output and Labour Productivity in Manufacturing for China, Japan, Korea and the United States in Circa 1935 by a Production PPP Approach
Full text linkFollowing the standard methodology for measuring industry-of-origin or production-side PPPs, this study compares the unit values of manufacturing products in China, Japan, Korea and the US to calculate unit value ratios (UVRs) and hence estimates PPPs for individual manufacturing industries using the US as the base country in circa 1935. Based on the products that could be matched between these countries, the estimated manufacturing production PPPs for China, Japan and Korea are only from half to two thirds of the prevailing market exchange rates, suggesting much lower cost of production in manufacturing in these countries than in the US. The estimated PPPs are used to calculate industry-level output and labour productivity in China, Japan and Korea relative to those of the US in circa 1935. The results show that the size of factory manufacturing in Japan was 12 percent of the US level whereas in China it was only one percent and even lower in Korea. In terms of comparative labour productivity, measured as PPP$ per hour worked with the US as the reference, Japanese and Korean manufacturing was 24 and 23 percent of the US level, whereas Chinese manufacturing was only 7 percent of the US level.Production (industry-of-origin) purchasing power parity (PPP), unit value ratio, comparative output and labour productivity, comparative advantage, economic development
The Internationalization and Performance of Korean and Japanese Firms: An Empirical Analysis Based on Micro-data
Full text linkBoth Korea and Japan are leading exporting countries of advanced manufactured products, and the competitive and efficient manufacturing activities are important pillars of the affluence of the two economies. Yet, comparing the manufacturing sectors of the two countries in the 1990s brings to light a startling contrast in their performance. Applying the same empirical method to the analysis of micro-data for Japanese manufacturing firms for 1994-2001 and Korean manufacturing plants for 1990-98, this paper examines differentials in Japanese and Korean productivity growth. This paper focuses on the role of competition in firm dynamics and on the importance of internationalization as a major determinant of firm performance.
Regional Inequality and Industrial Structures in Pre-War Japan: An Analysis Based on New Prefectural GDP Estimates
Full text linkStudies comparing regional income in Japan before and after World War II have frequently drawn a picture of radical change from an economy characterized by large regional disparities to one characterized by small regional disparities. This paper comes to a very different conclusion. Based on estimates of prefecture-level value added for five benchmark years from 1890 to 1940 (a detailed description of our estimation methodology is provided), we examine trends in the gap of economic development between prefectures during the pre-war period and find that this gap was much smaller than claimed in preceding studies and, in fact, not much greater than during the post-war period. Observing, moreover, a decline in inter-prefectural differences in terms of per-capita gross value added during the pre-war period, we conduct a factor analysis and find that a major reason for this decline was a decline in inter-prefectural differences in same-industry labor productivity. Thus, the picture of modern Japan's economic development presented here is very different from the one painted by preceding studies.
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
