Ideology and performance in public organizations
Full text linkWe combine personnel records of the United States federal bureaucracy from 1997 to 2019 with administrative voter registration data to study how ideological alignment between politicians and bureaucrats affects turnover and performance. We document significant partisan cycles and turnover among political appointees. By contrast, we find no political cycles in the civil service. At any point in time, a sizable share of bureaucrats is ideologically misaligned with their political leaders. We study the performance implications of this misalignment for the case of procurement officers. Exploiting presidential transitions as a source of “within-bureaucrat” variation in political alignment, we find that procurement contracts overseen by misaligned officers exhibit greater cost overruns and delays. We provide evidence consistent with a general “morale effect,” whereby misaligned bureaucrats are less motivated to pursue the organizational mission. Our results thus help to shed some of the first light on the costs of ideological misalignment within public organizations
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
Monocanna ovale Wang & Lin & Xu & Guo & Huang 2019, comb. nov.
No full textMonocanna ovale (Mayer, 1900) comb. nov. (Figs 6, 14–15) Multioralis ovalis Mayer, 1900: 54–55, pl. 30, figs. 129–130. Gastroblasta ovalis: Mayer, 1910: 281, pl. 35, figs. 7–8. Gastroblasta ovale: Bouillon et al., 2006: 417; Xu et al., 2012: 310, fig. 3. 48; Xu et al., 2014: 717, fig. 616a–b. Phialidium ovale: Kramp, 1961: 171; Xu & Huang, 1983: 101–102, pl. 1, figs. 1–2; Li & Chen, 1991: 90. Clytia ovalis: Guo et al., 2008: 231; Tang & Gao, 2008: 319. Material examined. 3 specimens (AOB-HL328–330) collected from Dapeng Bay, northern of the South China Sea, station V 4 (22°35 ˊ N, 114°19 ˊ E), depth 13.5 m, 26 August 2018, coll. Zike Zhao, Guanjie Min and Shihao Deng. Diagnosis. The species is different from others by following: umbrella elliptical in outline; a straight canal along major axis of bell; with 2 to 4 manubria along a straight canal; no centripetal canal; two small gonads near ends of canal; 12–25 short marginal tentacles; marginal statocysts slightly more numerous than tentacles, with one concretion. Description. Umbrella 2.4–4.0 mm in width, flat, elliptical or hemispherical; with a slender circular canal, and a straight canal along major axis of bell; with 2–4 manubria, 2 equally developed large manubria on either side of center of subumbrella, upon straight canal, and 2 small manubria upon same canal centrifugally away from larger manubria; without centripetal canal; 2 small gonads upon near ends of canal; with 12 to 25 short, simple, coiled marginal tentacles with well-developed basal bulbs; statocysts slightly more numerous than tentacles, usually 1, but occasionally 2, being found between each successive pair of tentacles, each with one concretion; velum simple and quite broad. Distribution. Haichang on the Jiulong River Estuary of Fujian (Xu & Huang, 1983); Dapeng Bay of Shenzhen and Beibu Gulf (Guo et al., 2008) of the northern South China Sea; Nansha Island (Li & Chen, 1991) of the southern South China Sea; Tortugas, Florida on the east coast of North America (Mayer, 1900); Brazil (Kramp, 1961). Remarks. This species was reported by Mayer (1900) as Multioralis ovalis from Tortugas, Florida, USA. Then, it was redescribed in detail (Mayer,1910), and transferred from the genus Multioralis to the genus Gastroblasta by having 2 or more radial canal and more than one manubrium. Kramp (1961) indicated that ovale could not be placed in the genus Gastroblasta, because its medusa had not centripetal canals and with numerous statocysts, and regarded it as an abnormal species of Phialidium (a junior synonym of Clytia). However, the change was not well accepted and the species was reported under Gastroblasta, Phialidium and by different scholars. Although only 10 specimens were obtained from the Dapeng Bay, their good preservation provides enough morphological evidences to us. A redescription of Monocanna ovale (Mayer, 1900) comb. nov. is done here as the type species of the genus Monocanna Xu, Guo &Wang, gen. nov.

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
