Dalopius mississippiensis Mathison 2014, new species
No full textDalopius mississippiensis Mathison, new species (Figures 1–2) Diagnosis. Dalopius mississippiensis fits Brown’s (1934) cognatus-group of Dalopius by having the phallobase at least half the total length of the aedeagus, truncate elytral apices, and pale humeral maculae on the elytra. It can be distinguished from the other members of this group by the characteristics of the male aedeagus, especially with regards to the shape of the parameres. Description. Holotype, male, housed in the CNCI, with label data: “MISS. Monroe Co./ca. 5 mi NE Hamilton/ 26 April 1991 /D. Pollock, J. MacDonald//Blacklight trap/ Dalopius mississippiensis Mathison HOLOTYPE ”. [the specimen had been broken and re-glued at the prothorax-mesothorax juncture.]. Body elongate, slightly convex. Length 6.8 mm, width 1.7 mm. Color dark brown; head darker; venter, margins of pronotum, humeral maculae, legs, and first two antennomeres red-brown; humeral maculae extending less than one-third length of elytra. Vestiture short, dense, yellow, evenly distributed over the body. Head as in other members of the genus. Antennae extending approximately two segments beyond apex of pronotal hind angles; antennomere III short, slightly longer than II, combined with II subequal to IV. Pronotum longer than wide, 2.2 mm long by 1.6 mm wide; widest anteriorly, slightly concave at the base of hind angles in dorsal view; punctures shallow, dense, umbilicate, separated by less than their own diameters; hind angles slightly divergent, unicarinate on dorsum. Hypomeron densely punctate, punctures very shallow, umbilicate. Elytra fusiform, sides subparallel over basal half in dorsal view, widest just beyond half-way, gradually tapering to obliquely truncate apex. Aedeagus as in Fig. 1. Phallobase large, nearly half the length of entire organ; median lobe gradually tapering to subacute apex; parameres with prominent shoulders basally, gradually narrowing to subacute apices, outer lateral margins angulate, with acute lateral expansions. Female unknown. Variation. A second specimen is 7.0 mm in length and with the reddish humeral macula slightly longer. Distribution. Currently known only from the type locality in Monroe County, Mississippi. Other material. Paratype, 1, male, with same data as holotype, deposited in the MEM, Starkville, MS. Etymology. This species is named for the state of Mississippi where it was collected. This is currently the only species of Dalopius recorded from Mississippi. Discussion. The placement of Dalopius mississippiensis falls in Brown’s (1934) cognatus-group, supported by the long phallobase, truncate elytral apices, and pale elytral maculae. Based on the lack of emargination at the apex of the paramere, and relative lengths of antennomeres II-IV, this species keys to D. virginicus Brown (1934). It can be separated from that species by the angulate the apices of the parameres. Externally, D. mississippiensis is largely indistinguishable from other members of the cognatus-group, other than being slightly paler in color. The length of the humeral macula is slightly longer in the secondary specimen than in the holotype, but this trait varies in other members of the cognatus-group. This represents the southernmost type locality for a Dalopius species in the eastern U.S.A. The town of Hamilton, MS is in the Fall Line Hills subregion of the Southeastern Plains. This is a very rugged terrain drained by tributaries of the Tombigbee and Tennessee rivers. The steep, dissected hills have narrow ridgetops and narrow valleys. The land cover is dominated by oak-hickory-pine forests with 400–700 ft of relief, and includes the highest point in Mississippi (Chapman et al. 2004). Most other records for Dalopius species in the southeast are in the Blue Ridge and Southwestern Appalachians in eastern Tennessee, North Carolina, South Carolina, and northern Georgia and Alabama. The Southeastern Plains may seem like an unusual place to find Dalopius, but the high, narrow ridgetops and valleys of the Fall Line Hills subregion may allow for relict distributions of otherwise boreal elaterid groups.Published as part of Mathison, Blaine, 2014, A new species of Dalopius Eschscholtz (Coleoptera: Elateridae: Elaterinae) from Mississippi, pp. 1-3 in Insecta Mundi 2014 (373) on pages 1-3, DOI: 10.5281/zenodo.517933

Cross // blacklight trap (2, MEM); FLA: Monroe Co, upper Key Largo, 6-9 June 1994, R. Androw, M. Brattain (3, BAMC). Etymology. The species epithet “tequesta” is treated as a noun in apposition and is in honor of the Tequesta indigenous people who once lived in southeastern Florida and the Keys, and are now apparently extinct. Notes. Dipropus tequesta is apparently endemic to southern-most Florida, and is morphologically similar to certain undescribed Dipropus species from Cuba. It differs from other described species of Dipropus in the eastern United States by the characters used in the key below, in addition to the combination of the antennal length, antennomere length ratio, pronotal punctation, and aedeagal (Fig. 2) characters as described and illustrated.Published as part of Mathison, Blaine A. & Johnson, Paul J., 2017, A new species of Dipropus Germar (Coleoptera: Elateridae) from Florida, with taxonomic and morphological notes and a new key to the species of the eastern United States, pp. 1-7 in Insecta Mundi 2017 (566) on pages 2-3, DOI: 10.5281/zenodo.517045
Clin Lab Med
Get PDFThe coccidians Cryptosporidium spp, Cyclospora cayetanensis, and Cystoisospora belli and the flagellate Giardia duodenalis are pathogenic protozoa associated with gastrointestinal manifestations. Diagnosis relies heavily on microscopy, and although ova-and-parasite examinations can detect Giardia and Cystoisospora, Cryptosporidium and Cyclospora often require specific diagnostic requests. Approved non-microscopy methods are available for Giardia and Cryptosporidium, although negative results are frequently followed by microscopic assays. Polymerase chain reaction-based methods are not frequently used for diagnosis of Giardia and Cryptosporidium and have been used primarily for epidemiologic or outbreak investigations of Giardia and Cryptosporidium.CC999999/Intramural CDC HHS/United State
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
