Aspects of activity coordination between two cooks in a professional setting
No full textIn this paper, we analyse data from a multi-view video recording (with two or three cameras) of two cooks preparing meals in the kitchen of an Italian restaurant.
The research program focuses on the verbal and non verbal modalities that the two cooks use for coordinating the activity of preparing a single dish or a sequence of dishes. The level of their coordination changes along with the different phases of the activity. The minimum level of coordination consists in a mutual attention which permits them to accomplish independent activities in sharing the different working emplacements of the kitchen. The maximum level of coordination corresponds to the co-accomplishment of a phase in sequence of actions. And between the two, various configurations can occur. Besides these cases, there are occasions in which one of the participants begins an action which is then interrupted or suspended by the intervention of the other participant or by her becoming available for accomplishing a particular task at that moment. The intervention of the other participant changes the configuration of the whole initiated action . The analyses will focus on those particular cases, which permit us to investigate the transition between individual actions and coordinated activity
Cooking together: activity coordination in professional cooking
No full textThe analysis focuses on verbal and non verbal modalities professional cooks use to accomplish a joined activity, which is the preparation of a meal.
The data are taken from the video recording of two cooks preparing meals in the kitchen of an Italian restaurant. The activity has been recorded with two cameras from two different points of view in order to obtain a more complete vision of the entire activity. The total amount of data corresponds to the preparation of four meals. The cooks are preparing the meal following the orders which are communicated by the waitress. For communicating the orders, the waitress enters the kitchen saying the order aloud and hanging up the written version of the order on the wall. The written order hanging on the wall functions as reference for the cooks’ evaluation of the sequential arrangement of the actions they are accomplishing.
The analysis shows how, in the context of a complex and shared activity, the accomplishment of an action can project the following relevant action organizing the activity of all participants. The performance of single actions, for example the action of putting a pot in a specific place or describing aloud what one’s is doing, can function as an organizational device of the whole activity of co-preparing meals
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
