Holotype ♂, paratypes 8♂ and 20♀ (NHMSU), CHINA: Chongqing, Wulong, Tudi Town, Tiansheng Village, Xiaodong Cave, 29°31.853'N, 107°50.817'E, altitude 1050 m, 17 October 2010, L. Dou and Y. Lin leg. Diagnosis. Male of S. wulongensis differs from males of all other congeners with the exception of S. bifurcata by the furcate embolus (Fig. 6E–e vs. Fig. 6A–D, 6a–d, 6G–H, 6g –h); it differs from male of S. bifurcata by the narrower, longer oval bulb, the embolus with two equilong tip branches, and the embolus starts from the submesialback surface of bulb, but the embolus of S. bifurcata with asymmetric branches that origins from prolateral surface of bulb (Fig. 6E–e vs. Fig. 6F–f). Female of S. wulongensis seems also close to S. bifurcata having a similar vulval structure, but it can be distinguished by the lager “ω”-shaped inner vulval plate, and the longer, weakly sclerotized central process (Fig. 7F vs. Fig. 7D).

S. bifurcata similar to S. wulongensis in the shape of palpal bulb and the configuration of vulva, but male of S. bifurcata can be distinguished from that of S. wulongensis by the starting position of embolus (Fig. 6F vs. Fig. 6E, the position indicated by the blue arrow) and the unequal length of branches of embolic tip (Fig. 6f vs. Fig. 6e); female of S. bifurcata separated by the smaller, “Ω”-shaped inner vulval plate, and the shorter central process (Fig. 8A vs. Fig. 8B).

Diagnosis. Male of this species is similar to S. halongense (Fig. 6A) and S. lenachanae (Fig. 6D), but can be distinguished from the latter two by the narrower, pointed embolic tip (Fig. 6b vs. Fig. 6a, 6d), and by the vestigial white eyespots lacking black ocular base in the both sexes (see Lin & Li, 2014: fig. 4G–H vs. Lin et al., 2017: figs 16E–F, 21A). Female is close to S. takensis sp. n. in having a similar configuration of vulva, but differs from the latter by the inverted triangular inner vulval plate, the wider, shorter central process (Fig. 7C vs. Fig. 5C–D).

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
lin-31, a Caenorhabditis elegans HNF-3/fork head transcription factor homolog, specifies three alternative cell fates in vulva development
No full textLate events in the cell-cell signalling pathway that controls the specification of vulva cell fates in C. elegans are characterized. The lin-31 gene acts downstream of the ras homolog let-60 and encodes a member of the HNF-3/fork head family of DNA-binding transcription factors. lin-31 regulates how vulval precursor cells choose their fate and in lin-31 mutants, these cells do not properly choose which fate to express and therefore adopt any of the 3 possible vulval cell fates in a deregulated manner..RE: 68 ref.; SC: CA; PE; 0TSource type: Electronic(1) http://upei-resolver.asin-risa.ca?sid=SP:CABI&id=pmid:&id=&issn=0890-9369&isbn=&volume=7&issue=6&spage=933&pages=933-947&date=1993&title=Genes%20and%20Development&atitle=lin-31%2c%20a%20Caenorhabditis%20elegans%20HNF-3%2ffork%20head%20transcription%20factor%20homolog%2c%20specifies%20three%20alternative%20cell%20fates%20in%20vulva%20development.&aulast=Miller&pid=%3Cauthor%3EMiller%2c%20L%20M%3bGallegos%2c%20M%20E%3bMorisseau%2c%20B%20A%3bKim%2c%20S%20K%3C%2Fauthor%3E%3CAN%3E19932337278%3C%2FAN%3E%3CDT%3EJournal%20article%3C%2FDT%3

This species can be separated from congeners by the unique brick red brown pubescence and unique elytral markings, larger body size, and unique golden brown metatarsi. Remarks.

The description of male genitalia was in older style (Huang & Lin 2 016) and some terminology terms are changed in this work: median lobe plus median struts = median lobe; internal sac = endophallus; basal armature = basal plate-like sclerites; rods of endophallus = rod-like sclerites.

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

SPATIAL CHOW-LIN METHODS: BAYESIAN AND ML FORECAST COMPARISONS
Full text linkCompleting data that are collected in disaggregated and heterogeneous spatial units is a quite frequent problem in spatial analyses of regional data. Chow and Lin (1971) (CL) were the rst to develop a uni ed framework for the three problems (interpolation, extrapolation and distribution) of predicting disaggregated times series by so-called indicator series. This paper develops a spatial CL procedure for disaggregating cross-sectional spatial data and compares the Maximum Likelihood and Bayesian spatial CL forecasts with the naive pro rata error distribution. We outline the error covariance structure in a spatial context, derive the BLUE for the ML estimator and the Bayesian estimation procedure by MCMC. Finally we
apply the procedure to European regional GDP data and discuss the disaggregation assumptions. For the evaluation of the spatial Chow-Lin procedure we assume that only NUTS 1 GDP is known and predict it at NUTS 2 by using employment and spatial information available at NUTS 2. The spatial neighborhood is de ned by the inverse travel time by car in minutes. Finally, we present the forecast accuracy criteria comparing the predicted values with the actual observations.
