Electroencephalography (EEG) Responses to Love-Related Facial Stimuli, 2005
No full text- 20 students of the Erasmus University Rotterdam in The Netherlands (11 women, 9 men, mean age 21.8 yrs, range 18-34) volunteered to participate. Only participants who were in love with someone of the opposite sex were included in the study. Other inclusion criteria were normal or corrected-to-normal vision, no diagnosis and no medication use. All participants were right-handed.
- Participants were in love, so the type of relationships were romantic relationships. The data is from individuals.
- Participants provided the two pictures of their beloved and friend prior to the testing session. These pictures were scanned, scaled to gray and resized to 200*250 pixels. At the testing session, the participants first gave informed consent. Second, the participants filled out a questionnaire about the duration and intensity of their love for the beloved, and the duration of any relationship with the beloved. Furthermore, they were asked to rate the attractiveness of the people on the three pictures (beloved, friend and unknown (fe)male) on a 9 point Likert scale (Likert, 1932). Similarly, the participants were asked how much they were in love with these people. Third, the participants filled out a Dutch translation of the Passionate Love Scale (PLS by Hatfield & Sprecher, 1978, in Hatfield, 1998). Fourth, the participants filled out a hand preference questionnaire (Van Strien, 1992). Finally, they completed a Dutch translation of the Affect Intensity Measure (AIM by Larsen, 1984, in Larsen & Diener, 1987). Next, the electrodes were placed, during which the experimenter asked the participants to remember pleasant, but not sexual events that had occurred with their beloved and friend. Furthermore, some instructions were given regarding limiting movement, eye blinks and tension of face and neck muscles during testing. During testing the participants sat in a comfortable chair in a soundproof, dimly-lit room. Participants completed an ERP task, and those data are published in Langeslag, Jansma, Franken, & Van Strien, 2007, Biological Psychology). The current data set involves an EEG task, because those data have not been published. Written instructions appeared on the screen, which the participants could read in their own pace. The participants were asked to focus on a fixation cross for 30 sec. This time interval was determined by short tones. These data served as a measure for the baseline condition. The remainder of the procedure of the EEG study resembled that of the fMRI study of Fisher and colleagues (2003). The participants were instructed to think about the pleasant event with their beloved or friend as their pictures appeared on the screen. Research has shown that viewing a pictures of a beloved and thinking back to specific relationship events are a good ways to elicit intense experiences of attraction (Mashek, Aron & Fisher, 2000). Furthermore, participants were instructed that they would have to count backwards aloud in steps of seven from a number (such as 5401) that appeared on the screen. This Serial Countback Task served as a distraction task to decrease carry-over effects, i.e. to erase feelings caused by the previous pictures (Mashek et al., 2000). The participant viewed the beloved for 30 sec, followed by the distraction task for 40 sec. Furthermore, the participants viewed the friend for 30 sec followed by 40 sec of the distraction task. This sequence was repeated 5 times. Halfway there was a break, after which the participants could continue by pressing a button. The total duration of the EEG study was approximately 14 min. Whether the beloved or the friend was the starting image, was balanced between participants. To make sure that the quality of the pictures of the beloved was no different from that of the pictures of the friends, these pictures were rated by men and women who did not participate in the two studies. They were recruited among students and employees of the Erasmus University Rotterdam and friends of the experimenter. Ten women (mean age 22.4, range 19-25) rated the 23 pictures of male faces (11 beloved, 11 friends and 1 unknown male) that were used in the main study. Similarly, ten men (mean age 22.2, range 19-30) rated the 19 pictures of female faces (9 beloved, 9 friends and 1 unknown female). For each pictures the men and women indicated how attractive they found that person on a 9 point Likert scale (Likert, 1932). Besides, they indicated whether they knew the person on the pictures. If they did know the person on a pictures, their attractiveness rating of that pictures was discarded from analyses. The stimulus protocol was programmed using E-Prime V1.1 (Psychology Software Tools, 2002). The EEG was recorded using a 32-channel amplifier and data acquisition software ActiveView (both BioSemi, ActiveTwo System). Sampling rate was 512 Hz. The Ag-AgCl ‘Pintype’ Active electrodes were fixed upon the scalp according to the 10-20 International System, by means of a headcap (BioSemi) and highly conductive electrode gel (Signa, Parker). Vertical electro-oculogram (VEOG) and horizontal electro-oculogram (HEOG) were recorded by attaching additional electrodes (UltraFlat Active electrodes, BioSemi) respectively above and below the left eye, and at the outer canthus of both eyes. The electrodes were attached to the skin by means of two-sides adhesive disks and highly conductive electrode gel (Signa, Parker). In the same way, reference electrodes were attached to the left and right mastoids. The EEG measurements were time locked to the stimuli by recording a trigger at the same time as the stimulus.
- This was a within-subject experiment in which electroencephalography (EEG) and questionnaire data were collected.
- These data were collected at the Erasmus University Rotterdam in The Netherlands. This study was exempt from IRB review
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
