    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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

    Evaluasi Adopsi Teknologi Budidaya dan Kelayakan Usahatani Padi di Provinsi Sulawesi Selatan (Kasus Desa Carawali dan Desa Salujambu)

    Rice is a strategic commodity, because as a staple food and a source of income for most rural households. Application of cultivation technology plays an important role to increase production and productivity of wetland rice. Therefore, the application of technological innovation of recommendation at the farm level is a strategy in the program of increasing national rice production towards sustainable self-sufficiency. This research was conducted in 2016 in Sidrap and Luwu districts, South Sulawesi Province by survey method. Primary data were collected through interviews to 80 farmers respondents by filling out a structured questionnaire. The data were processed by cross tabulation and the feasibility level of farming was measured by Gross B / C ratio and profitability. The results show that the adoption of paddy technology at the farm level has not been fully recommended. The result of cost and income analysis obtained value of B / C more than one, mean paddy field farming in research area give advantage and economically feasible cultivated. Keywords: Participation, Self-Sufficiency, Technology, Rice Farmin

    Impact of Climate Change (DPI) in West Java, especially the agricultural sector (food) are strongly influenced by the shift early growing season occurs 2 to 4 weeks since last 5 years. Some areas on the North Coast (North Coast of Java) early season retreat 1 to 2 months. As a result it affects the decline in production and productivity of rice, the price fluctuations of agricultural products and food insecurity disturbing. Purpose of the study looked at the impact of climate change on the productivity of rice paddy fields at the time of drought and floods and how the wisdom of farmers to cope with climate change. The research location Indramayu regency, as it is the central areas of rice-based food production, and the area has the insecurity of the impacts of climate change. The results showed the presence of DPI on the applied local wisdom flooded farmers (a) using the short-lived rice varieties, (b) rice varieties resistant varieties will be flooded and planted in one stretch with monoculture cropping systems. (C) use a pump to remove water . Dry season activities were implemented: (a) promote the planting schedule, (b) create a nursery, (c) use early maturing varieties, (d) cross dams, (e) motion to eradicate rats, (f) spray white butterfly pests (borers rods), (g) irrigation cultivation rationed sleigh, (h) conduct ceremonies (salvation alms earth), (i) and down motion field simultaneously. Productivity of rice under normal conditions GKP 5 tons gkp / ha (R / C 2.21). While the impact of flooded rice productivity on average only up to 3.5 tonnes gkp/ ha (R / C 1.01). Impact of drought rice productivity was only 4 quintals / ha (R / C 0:24). To overcome this required specific technologies and institutional development, and agricultural infrastructure, to support sustainable food self-sufficiency. Keywords: Mitigation.

    During 1997-2001 population of beef cattle farming in Nusa Tenggara Barat (NTB) has decreased 8.8% annually. It was because the number of beef cattle farming was not proportional with the number of its trading. On the other hand the trade of good quality of breeding cattle outer NTB make the population of beef cattle farming decreased. The purpose of this paper to analysis institution market, the role of beef cattle farming on financial aspect and effect of social economics farmer. Base on secunder and primer data this research showed that to increase population of beef cattle farming, industry development in the future in needed. Its mean that goverment must improve previos methode by make any kind policy anfd progamme that can support farmer and another market agent. Furthermore the policy should be abble to keep national cattle resources and to reduce dependently on import in NTB.Keywords: beef cattle farming, market institusion, goverment policy

    Dispelling the Myths Behind First-author Citation Counts

    We 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
