Holotype female of T. balanites from B. aegyptiaca, at Shambat city, North Sudan, December 1966 (coll. E.A. El-Badry); holotype female, one paratype male and one male of T. mangiferus from mango leaves, at Giza governorate, September 1977 (coll. M.A. El-Borolossy); one female from same substrate and locality, February 1987 (coll. M.A. Zaher); one female from organic manure at Nasser, Beni Suef governorate, April 2001 (coll. A.H.M. Romeih); two females from mango leaves, at Senuris, Fayoum governorate, December 2002 (coll. R.I.A. Abo-Shnaf); one male from same substrate and locality, July 2003 (coll. R.I.A. Abo-Shnaf); one female from same substrate and locality, January 2004 (coll. R.I.A. Abo-Shnaf); one female from apple leaves, at same locality, March 2003 (coll. R.I.A. Abo-Shnaf); two females from Z. jujube leaves, at the Faculty of Agriculture Farm, Cairo University, Giza governorate, August 2001 (coll. M.M. Ahmed). Previous records from Egypt. as T. balanites — Fayoum governorate (Romeih et al., 2010 b); Giza governorate (Zaher, 1986; Romeih et al., 2010 b); as T. egypticus —Cairo governorate (Zaher, 1986); Giza governorate (El-Badry, 1967 a; Zaher, 1986); as T. mangiferus —Giza, Ismailia and Matrouh governorates (Zaher, 1986). Remarks. Typhlodromus egypticus was originally described from the holotype female and T. mangiferus from an unstated number of type specimens, both from Giza governorate, Egypt. The original descriptions of T. egypticus and T. mangiferus were reasonably detailed and illustrated; setal measurements were provided for T. mangiferus but not for T. egypticus. Typhlodromus balanites was originally described from the holotype female, 34 paratype females and five paratype males collected in North Sudan. The original description was rather detailed, with illustrations and setal measurements. An examination of the type specimen of T. balanites showed this to be a junior synonym of T. egypticus. El- Badry (1967 a, 1970) reported the chelicera of T. egypticus to have no teeth [sic], while Chant & McMurtry (1994) mentioned species of what they called the “ egypticus species group” to have chelicera with few teeth [sic]. Despite our effort, it was not possible to obtain types of T. (A.) egypticus for examination in this study. Thus, the new synonymy proposed in this paper is based on an examination of types of T. mangiferus, on the original description of T. egypticus, on the fact that both nominal species were described from the same region and on the several additional females and males examined in this study. Our measurements of T. mangiferus holotype are close to those reported by Zaher (1986) for a single female, except z 2 (30 according to that author).Published as part of Abo-Shnaf, Reham I.

Finite Element Analysis of Dapped-Ended Concrete Girders Reinforced with Steel Headed Studs
No full textThe application of dapped-ended girders in concrete construction arises in situations where it is desired to maintain continuity between adjacent members. Dapping involves recessing the end of a girder such that it can be placed on to supporting components. Due to the sudden decrease in cross sectional area, significant shear strength in the member is lost and the introduction of a re-entrant corner makes the girder prone to shear cracking. Careful shear reinforcement must therefore be provided at the re-entrant corner. Using headed studs in place of conventional reinforcement was first proposed by Herzinger and El-Badry (2007) at the University of Calgary. They performed experiments which showed that headed studs were effective in maintaining the strength and ductility of girders reinforced using a combination of horizontal, vertical, and inclined configurations. The experimental data was compared with the shear friction and diagonal bending methods of analysis. Overall, the experiments and analytical methods showed good agreement, but the accuracy of the methods varied in certain situations depending on the layout of the headed studs. The current study is a finite element analysis (FEA) of seven of the specimens tested by Herzinger and El-Badry (2007) using software ABAQUS. Results show that the diagonal bending method is more suited for specimens with inclined reinforcement while shear friction best predicts members with only horizontal and vertical reinforcement. As well, in analyzing dapped-ended concrete girders, a variety of parameters can impact the results of the model, but proper calibration can lead to the models’ suitability in being used for future parametric studies
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
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
