Distribution. Egypt (Sidi Kreer, Abo-Talat, and El-Amria district). Etymology. This species is named in honor of Mrs. Hedaya H. Karam, professor of Economic Entomology at Alexandria University, Egypt. Biology. Larvae of B. karamae develop inside leaves of S. pruinosa (Chenopodiaceae). Attacked leaves do not show any external signs of infestation except for a dark reddish spot, but can be recognized once adults have emerged, leaving behind emergence holes and the protruding pupal exuviae. Each gall consists of a single chamber in which pupation takes place. The adults were collected from plants from the end of January to the beginning of March, and from the end of April to the middle of October, 2013. Baldratia karamae may have more than two generations per year. Remarks. According to Fedotova (1991 a) the genus Baldratia is divided into five groups on the basis of morphological characters of adults. By reviewing these characters, it was clear that the new species, B. karamae, belongs to the salicorniae Group, which is characterized by the apical lamella positioned at an obtuse angle relative to segment 9, and the lateral plate embraces the entire base of the apical lobe. The salicorniae Group previously contained three species, viz. B. salicorniae, B. suaedifolia, and B. balchanensis (Fedotova 1991 a, 1992). The thin spine of the female ovipositor is longer and thinner in B. suaedifolia, and B. balchanensis than in B. salicorniae. This new species has a long thin spine that does not exceed the base of the aculeus, in contrast to B. balchanensis which has a longer thin spine. Baldratia suaedifolia has a thin spine covered with split setae, while it is bare in B. karamae. Currently only five gall midge species are known to be associated with the host plant Suaeda (Gagné & Jaschhof 2014). Two of them, B. aelleni Möhn, 1969, and B. suaedae Möhn, 1969, were described on the basis of larvae alone (Möhn 1969), and can therefore not be compared to other adults in the genus. Baldratia karamae larvae that develop in leaves of Suaeda pruinosa, differ from the three other species, viz. B. occulta Dorchin, 2001, associated with S. monoica Forssk; B. suaedifolia Fedotova, 1991, associated with Suaeda acuminata (Meyer); and B. terteriani Mamaev & Mirumian, 1990, associated with Suaeda altissima (L.), on the basis published descriptions of these species (Mamaev & Mirumian 1990, Fedotova 1991 a, Dorchin 2001). An unique feature of the B. karamae is the stable number of antennal flagellomeres (2 + 10) in both sexes, in contrast to other species of Baldratia which have a variable number of flagellomeres between the sexes, viz. B. suaedifolia (2 + 12 in female versus 2 + 10 in male), B. occulta (2 + 13-14 in female versus 2 + 12 in male), and B. terteriani (2 + 14 in female versus 2 + 12 in male). The lateral plate of the ovipositor of B. karamae is broad at its base, narrow in the middle and covered with split setae, but B. occulta has a lateral plate which is narrow at the base and bearing 10-15 straight setae, with split setae only on the basal part. The lateral plate of B. terteriani has a small lateral projection at the base that is not present in B. karamae.Published as part of Elsayed, Ayman Khamis, Skuhravá, Marcela, Karam, Hedaya Hamza, Elminshawy, Abdelaziz & Al-Eryan, Mohamed Awad, 2015, New records and new species of gall midges (Diptera: Cecidomyiidae) developing on Chenopodiaceae in Egypt, pp. 105-115 in Zootaxa 3904 (1) on pages 108-110, DOI: 10.11646/zootaxa.3904.1.6, http://zenodo.org/record/23434
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
Primofavilla aegyptiaca Elsayed, new species
No full textPrimofavilla aegyptiaca Elsayed, new species Adult description. Color of freshly emerged females: head black, antennae brown, thorax dark brown, wings transparent, legs light brown, upper and lower parts of abdomen black, lateral parts red and covered with scales. Body length. 1.8 mm (n= 2) in female. Head (Fig. 19). Compound eyes with circular facets. Gap between eyes on vertex about 0-2 times as wide as facet. Palpi 2 -segmented, the second segment slender, elongated, slightly longer than the first. Antenna 2 + 10 - segmented; scape conical; pedicel rounded; flagellomeres barrel-shaped, each with two connected rings of circumfila, except the terminal flagellomere, with two sets of two connected rings of circumfila (Fig. 20). Thorax. Wing (Fig. 21) length about 1.5 mm (n= 2) in female; vein R 5 joining C at its mid-length; C broken beyond the junction point with R 5; M present; CuA simple. Tarsal claws (Fig. 22) curved and toothed. Empodia much shorter than claws, about as long as the small basal tooth. Female Abdomen. (Fig. 23): Tergites 1–7 rectangular, setulose, and with 1–2 posterior rows of strong setae; tergite 8 about 0.3 width of the tergite 7. Sternites 2–7 rectangular, setulose, with posterior row of hyaline setae. Ovipositor: segment 8 with lateral group of strong curved setae, the membranous part rugose with papillae surrounded with tiny spines. Lateral plate with ~ 26 strong, straight and thick setae. Aculeus curved and bare. Apical lamella oval, setose; the basal third of the dorsal margin covered with filiform short setae and the apical two thirds covered with short lanceolate setae. Holotype. Female, Egypt, Alexandria, El-Amria district (30 ° 59 '54.00"N, 29 ° 49 '7.00"E), 26.V. 2013, A. K. Elsayed, reared from leaf galls on leaves of Atriplex halimus. Paratypes. 1 female, 26.V. 2013, El-Amria district, Alexandria, reared by A. K. Elsayed from galls on leaves of Atriplex halimus. Distribution. Egypt, Alexandria, El-Amria district. Etymology. The name of that species is derived from Egypt. Biology. Larvae of P. aegyptiaca induce globular galls, 2-3 mm in diameter, on both surfaces of leaves (Fig. 8) of the salt marsh plant A. halimus. Each infested leaf has 2-6 galls, usually beyond the mid-rib. The galls were found in May and June 2013. The galls were collected and preserved in test tubes to rear the adult stage, but that method was not very successful, as only 2 females emerged and the pupation site was not determined. Another method was tested to rear the adults, the galls were collected and put in a plastic jar with soil at the bottom, but no adults emerged. Remarks. The three known species of Primofavilla, P. initialis Mamaev 1972, P. kaplini Fedotova 1991, and P. cystiphorae Fedotova 1991, are associated with Atriplex salina Siev., A. nana Parr-Sm., and A. tatarica L., respectively (Fedotova 1991 b, Gagné & Jaschhof 2014). The identification of Primofavilla species could be determined by the diagnostic morphological characters of the female ovipositor (Mamaev 1972, Fedotova 1991 b). The dorsal margin of the ovoid apical lobe of P. kaplini has only filiform setae, in contrast to P. aegyptiaca, P. cystiphorae and P. initialis, which have the filiform setae only on the basal third of the dorsal margin with the remaining setae either lanceolate (P. aegyptiaca and P. cystiphorae) or squamiform (P. initialis). Primofavilla aegyptiaca is closest to P. cystiphorae, but the former has dorsal and ventral sclerotized plates at the base of segment 9 of the female abdomen, while the latter does not. Primofavilla aegyptiaca also differs from P. cystiphorae in the distribution and number of strong setae on the lateral plate, which do not extend to the ventral side in P. aegyptiaca, unlike in P. cystiphorae. In addition to these differences, P. aegyptiaca has a bare saddle-like projection at the base of the aculeus. Therefore, P. aegyptiaca is considered to be a new species. Very similar galls were shown by De Stefani (1942) on the same host plant in Sicily, Italy, but the gall inducer was not identified, strongly suggesting the presence of P. aegyptiaca in Italy.Published as part of Elsayed, Ayman Khamis, Skuhravá, Marcela, Karam, Hedaya Hamza, Elminshawy, Abdelaziz & Al-Eryan, Mohamed Awad, 2015, New records and new species of gall midges (Diptera: Cecidomyiidae) developing on Chenopodiaceae in Egypt, pp. 105-115 in Zootaxa 3904 (1) on pages 111-112, DOI: 10.11646/zootaxa.3904.1.6, http://zenodo.org/record/23434
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

Generation and analysis of transgenetic mice expressing catalytically inactive recombination activating gene-1
No full textThe proteins encoded by the recombination activating genes (RAG1 and RAG2) are lymphoid cell-specific endonucleases that initiate V(D)J recombination; the mechanism by which the exons that encode the variable portion of both B and T cell receptors are assembled somatically from several variable (V), joining (J) and sometimes diversity (D) germline gene segments. The enzymatic activity of the RAG proteins has been attributed to three acidic residues (Asp600, Asp708, and Glu962) within RAG1. These residues constitute the DDE motif which functions as the active site for the RAG proteins by coordinating metal ions required for catalysis of DNA cleavage. Mutation of any of these residues abrogates V(D)J recombination without affecting the DNA binding activity of the RAG protein complex. Accordingly, we have speculated that ectopic expression of a catalytically inactive form of RAG1 in vivo may suppress the activity of endogenous RAG1 and V(D)J recombination in a dominant negative pattern.
To test this hypothesis we have generated transgenic mice overexpressing a catalytically deficient form of RAG1 in which the three residues comprising the DDE motif have been mutated to alanine. We show here that transgenic mice, but not non- transgenic littermates, accumulate an unusual population of B cells that are characterized by low expression of the pan B cell marker, CD45R (B220), referring to them as B220k> B cells. Extensive phenotypic characterization using How cytometery shows that the B22010 B cells are phenotypically resemble the immature transitional- and Bl- B cell. Total splenocytes and sorted splenic B22010 B cells of transgenic mice showed significant reduction in their proliferative capacity in response to B cell receptor cross-linking. Moreover, serum levels of immunoglobulins (IgM and IgG) are significantly reduced in transgenic mice when compared to non-transgenic littermates.
Taken together, these findings are consistent with significant impairment in B cell maturation due to suppression of secondary rearrangement mediated by the RAG proteins to edit receptor specificity in self-reactive B cells. This model may provide an opportunity to dissect the mechanisms of tolerance and autoimmunity in peripheral B cellsProQuest Traditional Publishing Optionxvii, 158 page
Higgs mass corrections in the SUSY B-L model with inverse seesaw
No full textIn the context of the Supersymmetric (SUSY) B-L (Baryon minus Lepton number) model with an inverse seesaw mechanism, we calculate the one-loop radiative corrections due to right-handed (s)neutrinos to the mass of the lightest Higgs boson when the latter is Standard Model (SM)-like. We show that such effects can be as large as O(100) GeV, thereby giving an absolute upper limit on such a mass around 200 GeV. The importance of this result from a phenomenological point of view is twofold. On the one hand, this enhancement greatly reconciles theory and experiment, by alleviating the so-called 'little hierarchy problem' of the minimal SUSY realization, whereby the current experimental limit on the SM-like Higgs mass is very near its absolute upper limit predicted theoretically, of 130 GeV. On the other hand, a SM-like Higgs boson with mass below 200 GeV is still well within the reach of the Large Hadron Collider (LHC), so that the SUSY realization discussed here is just as testable as the minimal version
Pragmatic Case Studies as a Source of Unity in Applied Psychology
No full textTo unify or not to unify applied psychology: that is the question. In this article we review pendulum swings in the historical efforts to answer this question—from a comprehensive, positivist, “top-down,” deductive yes between the 1930s and the early 60s, to a postmodern no since then. A rationale and proposal for a limited, “bottom-up,” inductive yes in applied psychology is then presented, employing a case-based paradigm that integrates both positivist and postmodern themes and components. This paradigm is labeled “pragmatic psychology” and, its specific use of case studies, the “Pragmatic Case Study Method” (“PCS Method”). We call for the creation of peer-reviewed journal-databases of pragmatic case studies as a foundational source of unifying applied knowledge in our discipline. As one example, the potential of the PCS Method for unifying different angles of theoretical regard is illustrated in an area of applied psychology, psychotherapy, via the case of Mrs. B. The article then turns to the broader historical and epistemological arguments for the unifying nature of the PCS Method in both applied and basic psychology.Peer reviewe
Right-handed sneutrino-antisneutrino oscillations in a TeV scale Supersymmetric B-L model
No full textWe explore right-handed sneutrino-antisneutrino mixing in a TeV scale B-L extension of the Minimal Supersymmetric Standard Model (MSSM), (B-L)SSM, where a type I seesaw mechanism of light neutrino mass generation is naturally implemented. The constraints imposed on the mass splitting between heavy right-handed sneutrino and the corresponding antisneutrino by the experimental limits set on the light neutrino masses are investigated. We also study direct pair production of such right-handed sneutrinos at the Large Hadron Collider (LHC) and its decay modes, emphasising that their decay into same-sign di-lepton pairs are salient features for probing these particles at the CERN machine. Finally, the charge asymmetry present in such same-sign di-lepton signals is also analysed and confirms itself as a further useful handle to extract information about the oscillation dynamics
