Diverse pattern of strain at the Afar triple junction
No full textStrain and seismicity show us the mode by which deformation is accommodated in rifting continents. Here we present a combined analysis of InSAR derived strain maps and seismicity of the Afar triple junction from 2006 to 2010. Our analysis shows that that the plate spreading motion is accommodated in different modes. A dogbone-shaped seismicity and strain distribution dominates the northern branch of the triple junction, likely as a result of repeated dike intrusions 2005-2010. In the eastern branch strain is distributed across the central part of several overlapping rifts while seismicity appears decoupled from strain and it focuses at the rifts tips. A third branch shows a narrow and elongated zone of both high strain and seismicity. The pattern suggests that the history of magmatic intrusions and rifting events creates a diverse triple junction accommodation zone
Strain accommodation in transitional rifts: extension by magma intrusion and faulting in Ethiopian rift magmatic segments
No full textActive deformation within the northern part of the Main Ethiopian Rift (MER) occurs within approximately 60 km-long, 20 km-wide ‘magmatic segments’ that lie within the 80 km-wide rift valley. Geophysical data reveal that the crust beneath the <1.9 Ma magmatic segments has been heavily intruded; magmatic segments accommodate strain via both magma intrusion and faulting. We undertake field and remote sensing analyses of faults and eruptive centres in the magmatic segments to estimate the relative proportion of strain accommodated by faulting and magma intrusion and the kinematics of Quaternary faults. Up to half the ?10 km-long normal faults within the Boset-Kone and Fantale-Dofen magmatic segments have eruptive centres or extrusive lavas along their length. Comparison of the deformation field of the largest Quaternary fault and an elastic half-space dislocation model indicates a down-dip length of 10 km, coincident with the seismogenic layer thickness and the top of the seismically imaged mafic intrusions. These relations suggest that Quaternary faults are primarily driven by magma intrusion into the mid- to upper crust, which triggers faulting and dyke intrusion into the brittle upper crust. The active volcanoes of Boset, Fantale and Dofen all have elliptical shapes with their long axes in the direction N105, consistent with extension direction derived from earthquake focal mechanisms. Calderas show natural strains ranging from around 0.30 for Boset, 0.55 for Fantale, and 0.94 for Dofen. These values give extension strain rates of the order of 0.3 microstrain per year, comparable to geodetic models. Structural analyses reveal no evidence for transcurrent faults linking right-stepping magmatic segments. Instead, the tips of magmatic segments overlap, thereby accommodating strain transfer. The intimate relationship between faulting and magmatism in the northern MER is strikingly similar to that of slow-spreading mid-ocean ridges, but without the hard linkage zones of transform faults

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Habitat and distribution. Parasenegalia visco has been collected from seasonally wet mountains, deciduous forests, riparian forests, yungas, disturbed second-growth forests, and thickets, from 750 to 3000 m in northern Argentina, through Bolivia, northern Chile, and Peru. The taxon is commonly cultivated in Peru as well as where native (Rico Arce, 2007). Phenology. Parasenegalia visco flowers from October through January. Local names and uses. Local names include visco, arca, viscote, viscote negro, viscote blanco, and visite (Rico Arce, 2007). Parasenegalia visco is commonly cultivated for its wood. IUCN Red List category. Parasenegalia visco is assessed as Data Deficient (DD) at this time (IUCN, 2 0 0 1) but is an abundant species of southern South America and is commonly cultivat- ed in Argentina, Chile, Peru, Uruguay, and South Africa as an ornamental and as a fast-growing tree for cabinet wood (Rico Arce, 2 0 0 7). Parasenegalia visco is also known from numerous collections from Argentina and Bolivia and is probably of Least Concern (LC). Discussion. Parasenegalia visco is a large South American tree that is commonly cultivated and economically important for wood products. The globose inflorescence more than 16 mm across, along with the small leaflets (3–7 X 0.8–2.1 mm) with bluish purple midveins, distinguish this species from other members of the genus. Paul G. Lorentz was a German botanist and professor at the University of Córdoba, Argentina, until 1 8 74. His vascular plant collections at GOET were the sources for species described by Grisebach in his Plantae Lorentzianae (1 8 7 4) and Symbolae ad Floram Argentinam (1 8 7 9). The collection Lorentz 3 4 0 at GOET has an original label identifying the species as Acacia visite, which corresponded to the first name used by Grisebach in Plantae Lorentzianae (1 87 4: 1 3 5), which was emended in this same work to Acacia visco (1 87 4: 2 7 9). Although no collection was specified in the protologue, Lorentz can be assumed to be the collector (Stafleu & Cowan, 1 9 7 6: 1 0 1 1, 1 98 1: 1 5 7) for species similarly described by Grisebach. The lectotype at GOET (1 1 4 63) bears an original label with the spelling as Acacia Visite. This species was cited as introduced into South Africa as Acacia visite Griseb. (Ross, 1 9 7 5). Two common names were mentioned in the protologue by Grisebach (1874) for his Acacia species number 269 (1874: 135), as ‘‘[n]omen vernac. Visite, Visco.’’ These vernacular names were a source of confusion for the species epithet. On page 135, Grisebach described the new species as ‘‘269. Acacia Visite Gr.,’’ but this was emended by him in the same work on page 279 under ‘‘Verbesserungen’’ (Improvements), as ‘‘S. 135 nr. 269 statt [instead of] A. Visite Gr. lies [read] A. Visco Lor. in litt.’’ It is this emendation that indicated Grisebach’s intent to change the epithet to the other vernacular name, acknowledging Lorentz as well. Grisebach’s intent was further supported in his later treatment of Acacia in Symbolae ad Floram Argentinam (1879: 122), where the species was also cited as ‘‘ A. Visco Lor. mscr. – Syn. A. Visite Pl. Lor. [269],’’ with the number corresponding to the species number in the previous 1874 treatment in his Plantae Lorentzianae. The specimen chosen as the lectotype of Acacia concinna is representative of that species and is from the home institution (SGO) of Philippi, the describing author. No specimen was cited by Manganaro (1919: 128– 129) in the protologue for Acacia platensis, although she did note the species as ‘‘visto cultivada esta planta en Buenos Aires y en La Plata....’’ Spegazzini (1921) transferred the name to the genus Manganar- oa Speg. based on Manganaro’s study. Cialdella cited the specimen with the word ‘‘typus’’ written on it, presumably used by both previous investigators, LP [barcode] LPS24314, as the holotype. We interpret this as a de facto lectotypification. Although the name Mimosa polyphylla Clos was written on the type specimen of Acacia polyphylla Clos in Gay, apparently this name in Mimosa was never published. If this name were published, it would be the oldest name for Parasenegalia visco, but still illegitimate. The SGO lectotype chosen for A. polyphylla is representative of the species and is from the home institution of the describing author. Kuntze (1898: 47) described Acacia riparia var. angustifoliola from two countries as ‘‘Bolivia: Sierra de Santa Cruz 2000 m. and Argentina: Provinz Santiago.’’ Of these two possible syntypes, the NY (barcode NY0 0 0 0 1 5 4 2) sheet from Bolivia was annotated by Seigler and Ebinger (2009) as the holotype, emended here as the lectotype. A syntype of Manganaroa subsericea from Argentina (prov. Buenos Aires, La Plata, Jardín Botanico ‘‘Facultad de Agron.’’), also identified as the collection C. L. Spegazzini s.n., is at LP (LPS- 14305) (Cialdella, 1984). Specimens examined. ARGENTINA. Catamarca: Andalgala, 1 9 5 0 m, 2 8 Nov. 19 4 6, C. A.

Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
