Changing Employment Structure in Middle-South Kyushu : the Analysis in the 1990's by Population Census and Establishment Census
Full text linkThis paper analyses changes m the employment structure in Middle South Kyushu after 1970, especially in the 1990's. For this purposes, the author uses principal component analysis and cluster analysis. The districts for these analyses are 234 administrative units (shi, cho, son) in Kumamoto, Miyazaki and Kagoshima prefectures. The results are summarized as follows. The employed persons in construction industry have increased in the 1970's and the period of 1991-1996, and decreased in the period of 1996-1999. These changes reflect the movement of the Japanese public investment policy after 1970. The employed persons in manufacturing industry have decreased in 1991-1999 year period. The decrease of the employed persons was remarkable with manufacture of textiles and manufacture of apparel and other finished textile products. The employed persons in these two types of manufacturing sectors decreased markedly in the districts that showed more than 10 percent in the percentage of these manufacturing sectors in 1991. In 1970-1990 year period the employed persons in service industries have increased remarkably in the districts which have a large growth in population. In the 1990's, however, the employed persons in service industries showed a tendency of increasing even in the districts that have a decrease in population. Moreover, the employed persons have increased remarkably in the medical service and the welfare service sector for the elderly in the 1990's
Changing Labor Market in Japan since the end of World War II
Full text linkThe purpose of this paper is to clarify changes in the spatial structure of the labor market in Japan since the end of World War II. The author therefore discusses the following points: 1) the changes in the labor market in Japan, 2) the spatial structure of labor market in Japan, The results are summarized as follows. In labor market studies, it has been recognized that the labor market is not a homogeneous structure but a segmented one, because there are some differences among the labor force in terms of wage disparity, labor movement, etc. In recent years, much research indicates that the boundaries of the segmentation of the labor market are fluid and indistinct. However, Labor economics are not very interested in issues related to spatial relations. In Geography labor market studies have changed in scope since the 1960s. Since the 1960s a number of manufacturing plants for, notably, textiles and electronics have been located in the rural areas to take advantage of cheap labor. These factories have influenced the local labor market and the occupational structure in this area, as would be expected. Following the collapse of the ""bubble economy"", young people entering the labor market as non-regular workers have increased in metropolitan areas. In the 1990s, production from manufacturing tended to decline in Japan. As a result of this decline, both the proportion of part-time workers and the unemployment rate increased. On the other hand, we can see some growth in the welfare service sector for the elderly in the rural areas in the 1990s. However, this sector can be characterized by such working conditions as low wages and instability of status. In order to develop research methods in this field further, we have some issues to resolve: 1) the character of spatial structure of the labor market in Japan since the 1990s, and 2) the mechanism of the regional differences on the labor market condition
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

Effective Dini's Theorem on Effectively Compact Metric Spaces
No full textAbstractWe show that if a computable sequence of real-valued functions on an effectively compact metric space converges pointwise monotonically to a computable function, then the sequence converges effectively uniformly to the function. This is an effectivized version of Dini's Theorem
