California Poll: 6203 -- July 12-19, 1962
No full textThe Field Poll, established in 1945 as The California Poll by Mervin Field, has operated continuously as an independent, non-partisan, media-sponsored public opinion news service. Each year the Field Polls cover a wide range of political and social topics examining California public opinion. Continuing measures are made of voter support for leading political figures vying for major state and federal offices, job ratings of important political figures and reactions to significant political events. Voter awareness, understanding and predispositions of major campaign issues and salient statewide ballot propositions are also tracked over time. For poll 6203 N=1210
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Analisis Reliability Dan Safety Integrity Level (SIL) Dengan Metode Risk Graph Dan Fault Tree Analysis (FTA) Pada Boiler (B-6203) Pabrik III PT. Petrokimia Gresik
Get PDFBoiler (B-6203) merupakan unit yang digunakan untuk men-supply steam pada steam generator pabrik III PT. Petrokimia Gresik. Unit ini merupakan unit penting pada pabrik III karena apabila terjadi kegagalan pada B-6203 maka akan menghentikan semua proses pada pabrik III. Dengan menentukan empat buah node pada unit Boiler B-6203, yaitu economizer, steam drum, superheater dan burner diketahui bahwa laju keandalan hingga mencapai keandalan minimum menurut standart perusahaan yaitu 0.6. Nilai keandalan sistem pada rentang waktu 2000 jam atau 3 bulan yaitu 0.52. Waktu interval maintenance berada pada range 3750 jam hingga 26000 jam. Valve FV-6212 memiliki interval waktu maintenance yaitu 3750 jam operasi. Pada analisa Safety Integrity Level (SIL) kuantitatif dengan metode Fault Tree Analysis (FTA), diperoleh nilai SIL sistem B-6203 yaitu SIL 2 dengan nilai PFD 0.00102. Sementara pada analisa SIL semi-kuantitatif dengan metode Risk Graph diperoleh hasil SIL 1 pada node economizer, steam drum dan superheater. Node burner memperoleh SIL 2 karena pada komponen tersebut apabila terjadi kebocoran pada aliran natural gas, maka dapat menimbulkan api hingga ledakan pada plant.

Boiler (B-6203) was unit used to supply steam in the steam generator third factory PT. Petrokimia Gresik. B-6203 was an important unit. If there were failure on the B-6203, the system would stop all processes on the plant. There were four nodes on the unit Boiler B-6203, such as the economizer, steam drum, superheater and burner. The minimum reliability reliability according to standard company is 0.6. The value of system reliability on a span of 2000 hours or 3 months that is 0.52. The interval of maintenance schedule in the range of 3750 hours until 26000 hours. FV-6212 has the lowest interval of maintenance schedule in 3750 hours of operation. In the analysis of Safety Integrity Level (SIL) with quantitative methods, Fault Tree Analysis (FTA), Boiler (B-6203) obtained with SIL 2 PFD value of 0.00102. The value of SIL with semi-quantitative method, risk graph method, given result SIL 1 in node economizer, steam drum and superheater. Node burner obtained SIL 2 due to the components in the event of a leak on the flow of natural gas. It could cause a fire to an explosion in the plant
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
The new AM Her system RX J0704.2+6203
No full textWe report here on the identification and study of the
optical counterpart of the ROSAT source RX J0704.2+6203.
Extensive spectral and photometric observation showed that the object belongs
to the class
of magnetic Cataclysmic Variables. We determined the orbital period of the
system to be 9727
and estimated the strength of its magnetic field to be on the order of 20 MG. The system was observed
in both high and low states, common for its class. Other parameters of the
magnetic close binary
system were estimated. The spectral and photometric behavior of
the object is similar to that of the well studied polar BL Hyi
