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

1967 razor clam surveys
Get PDFRazor clams are found in isolated areas all along the Oregon coast. However, 90% of the harvest takes place on the Clatsop Countty beaches. Along the rest of the coast, digging is sporadic and of minor importance. This report summarizes the data for 1967 for several beaches south of Seaside. The areas are combined geographically into two groups, northern and southern. The northern group includes the Columbia River, Indian, Crescent, Cannon, Arch Cape, Cove, and Short Sand beaches. The southern group includes Bastendorff, Whiskey Run, and Myers Creek beaches. Some midcoast areas were not sampled in 1967 and are not included in this report.
Sampling of clam diggers was concentrated at the northern beaches during the July I5-August 31 closure of Clatsop beaches because some Cannon Beach people feared an invasion of personal-use and commercial diggers. They were assured this would not happen, but no data were available to support the contention.
The southern beaches were checked incidental to other work. Hence, the data are biased toward the late tides of each series when digging is usually poor

Status of the Clatsop Beach razor clam stocks
No full textThe OFC staff had been investigating razor clam stocks in Oregon since 1949, and this report outlines their findings up to 1964. It gives the number of razor clams harvested as well as the number of diggers, and the age composition of those clams harvested. Finally, it discusses the increase in clam wastage from 1949-1964

Abandoned crab pots near Cannon Beach, Oregon
Get PDFThe State Police in Astoria informed the Fish Commission on October 12, 1970, that some 100 crab pots were in the ocean in 3-10 fathoms of water near Cannon Beach. This is about 23 miles south of the Columbia River within the 3-mile limit. According to one local crab fisherman, the pots had not been pulled since September 1, 1970, and probably longer. The Fish Commission concurred that the pots should be confiscated. Sgt. Ken Moore, Oregon State Police, contracted a boat and crew to pull the pots. Laimons Osis represented the Fish Commission to obtain biological data on the crabs caught

The 1964 Clatsop Beach personal-use razor clam fishery
Get PDFThe personal-use razor clam fishery was sampled from April to September 1964 for number and age composition of clams dug and number and distribution of diggers. A wastage estimate was also determined

The 1965 personal-use razor clam fishery
No full textThis report discusses public interaction with personal-use fisheries. It also discusses reasons for razor clam violations and means taken to try and decrease them. Finally, it gives the total harvest and age composition data, and contains the results of a survey of clam diggers on Clatsop County beaches for 1965

Information report: utilization and regulation of Clatsop Beach razor clam stocks
Get PDFThis report has a review of razor clam regulations on both personal and commercial diggers. It contains the harvest numbers for several years, as well as their age composition. The report describes the harvest and wastage of young clams, as well as discussing possibilities for decreasing that wastage, with focus on closing beaches to clamming. It discusses a questionnaire meant to explain the problem and possible solutions to diggers. The report concludes with a final discussion of benefits to temporarily closing certain beaches
