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

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
Modeling squeeze films in the vicinity of high inertia oscillating microstructures
No full textThis work investigates the effect of various assumptions proposed by the classical Reynolds lubrication equation. In particular, a microplate oscillating at high frequencies (beyond cutoff) and high velocities leading to appreciable displacement within the film gap is studied. An analytical model is derived with special emphasis on the fluid's inertia effect on the fluid-solid interface. By implementing the direct simulation Monte Carlo (DSMC) method, a numerical method for modeling rarefied gas flow, the analytically based model is adjusted for the force exerted by the gas on the oscillating micro-structure to capture various significant effects related to the fluid's inertia, compressibility, stiffness, and damping.

Niveles s\ue9ricos de apolipoprote\uedna b en diab\ue9ticos tipo 2 con evidencia de enfermedad coronaria arterial aguda. Servicio de Medicina Interna. Hospital Central Universitario "Dr. Antonio Mar\ueda Pineda". Mayo 2001- 2002.
No full textCon el objetivo de conocer los niveles s\ue9ricos de Apolipoprote\uedna B en pacientes diab\ue9ticos tipo 2 y no diab\ue9ticos con evidencia de Enfermedad Coronaria Arterial Aguda que ingresaron en los Servicios de Medicina de Agudos y Subagudos del Hospital Central Universitario "Dr. Antonio Mar\ueda Pineda" entre los meses de Mayo del 2001 y Mayo del 2002, se realiz\uf3 un estudio descriptivo de corte transversal. La muestra estuvo constituida por 26 pacientes masculinos con diagn\uf3stico de Enfermedad Coronaria Arterial Aguda, distribuida en 2 grupos, 12 diab\ue9ticos tipo 2 y 14 no diab\ue9ticos. Se determinaron las concentraciones s\ue9ricas de Apolipoprote\uedna B y la glicemia en ayunas para cada grupo. No hubo diferencias estad\uedsticamente significativas al aplicar la Prueba de T de Student, entre la edad, el peso, la talla y el Indice de Masa Corporal (IMC) entre los grupos. El 58,33% de los diab\ue9ticos y el 57,14 de los no diab\ue9ticos presentaron niveles elevados de Apolipoprote\uedna B (>109 mg%), con medias de 104,3 mg% para los diab\ue9ticos y 117,3 mg% , diferencia estad\uedsticamente no significativa (p 0,21). La glicemia en ayuna estuvo elevada en ambos grupos a predominio de los diab\ue9ticos con media de 179,3 mg% y para los no diab\ue9ticos de 113 mg% (glicemia basal alterada) sin significancia estad\uedstica (p 0,06). Al aplicar el Indice de Correlaci\uf3n de Pearson se observ\uf3 una correlaci\uf3n negativa entre los niveles de Apolipoprote\uedna B y la glicemia en ayuna en los diab\ue9ticos y una correlaci\uf3n positiva con el tiempo de evoluci\uf3n de la Diabetes, ambas sin significancia estad\uedstica. La Hipertensi\uf3n Arterial fue la comorbilidad m\ue1s frecuente (53,32%). La mayor\ueda de los pacientes (40%) con niveles elevados de Apolipoprote\uedna B ten\uedan edades comprendidas entre 58 y 63 a\uf1os. Sobre la base de estos resultados se concluye que los niveles s\ue9ricos de Apolipoprote\uedna B se elevan tanto en pacientes diab\ue9ticos como no diab\ue9ticos, lo que sugiere su independencia como factor de riesgo en la Enfermedad Coronaria Aguda, al relacionarla con el estado diab\ue9tico.
Mapping and Performance Analysis of Lookup Table Implementations on Reconfigurable Platform
No full textReconfigurable computing has a recognized potential in processor design. It provides a middle trade-off between speed and flexibility. It provides performance close to application-specific-hardware, yet preserves the general-purpose-processor flexibility. This paper presents the mapping and performance analysis of the implementation of the lookup table for two encryption algorithms, namely Rijndael and Twofish, on a coarse grain dynamic reconfigurable platform, namely MorphoSys. MorphoSys is a dynamic reconfigurable architecture targeted for computer intensive applications with parallel nature. Since the MorphoSys does not support the indirect addressing, we present in this paper a methodology to implement an alternative. We present the details of the mapping of the two lookup tables with thorough analysis. The methodology we used can be utilized in other Memoryless systems. Finally, an instruction set extension was proposed to enhance the performance. © 2007 IEEE.Almaini AEA, 1994, ELECT LOGIC SYSTEMS; BAGHERZADEH N, 2000, J VLSI SIGNAL PROCES; DAEMEN J, 2002, AES ADV ENCRYPTION S; DIAB H, 2003, ACSIEEE INT C COMP S; Green D.H., 1986, MODERN LOGIC DESIGN; Hartenstein R, 2001, DESIGN AUTOMATION TE; HARTENSTEIN R, 2001, P C AS S PAC DES AUT; HAUCK S, 1998, FUTURE RECONFIGURABL; *IST, ARCH METH DYN REC LO; MAJZOUB S, 2003, ACSIEEE INT C COMP S; Schneier B., 1996, APPL CRYPTOGRAPHY PR; Schneier B., 1998, TWOFISH 128 BIT BLOC; Singh H, 2000, IEEE T COMPUT, V49, P465, DOI 10.1109-12.859540; TESSIER R, 2002, RECONFIGURABLE COMPU10

Opportunities for Producing Table Grapes in Egypt for the Export Market: A Decision Case Study
No full textThe Barakat Fruit Farm desires to increase their share of the exportable grape market in Egypt. Unfortunately, the grape cultivars currently cultivated by the farm bear fruit after the early market window to the European Union when prices are high. An analysis of the company, competition, consumer, market channel, and conditions, provides insight into possible solutions to the challenges faced by the farm management. Designed for undergraduate classroom use, this case encourages students to think outside of traditional production techniques to arrive at solutions that are viable from both crop culture and financial standpoints.Decision case, horticulture, agriculture economics, grape production, Production Economics, Teaching/Communication/Extension/Profession, Q10, Q11,
MorphoSys reconfigurable hardware for cryptography: The twofish case
No full textThis paper presents the mapping and performance analysis of the Twofish algorithm on MorphoSys. MorphoSys is a reconfigurable architecture that can provide high performance compared to custom hardware and yet preserves a level of flexibility compared to general-purpose processors.With today's high demand for secure data transfer mediums including wired and wireless networks, there is a growing demand for real-time implementation of cryptographic algorithms. The choice of the Twofish algorithm, one of the five AES finalists, is because it is computationally intensive algorithm. It requires lookup tables, logical and arithmetic computations that stipulate high flexibility and performance. So it is a perfect algorithm to be mapped in order to evaluate such hardware. © 2010 Springer Science + Business Media, Inc.Al-Khalidy M, 2004, INT C CURR ISS BUS I; Almaini AEA, 1994, ELECT LOGIC SYSTEMS; Bagherzadeh N, 2000, J VLSI SIGNAL PR MAR; Damaj I, 2002, LECT NOTES COMPUT SC, V2438, P1076; Diab H, 2003, ACS IEEE INT C COMP; Ferrandi F., 2005, Proceedings. 19th IEEE International Parallel and Distributed Processing Symposium; Galanis MD, 2005, IEEE INT SYMP CIRC S, P1206, DOI 10.1109-ISCAS.2005.1464810; Galanis MD, 2004, P FPGA FEBR 2004; Galanis MD, 2004, P 13 INT C FIELD PRO; Ghaffari F, 2007, LECT NOTES COMPUT SC, V4050, P179, DOI 10.1007-978-3-540-71528-3_12; Green D.H., 1986, MODERN LOGIC DESIGN; Hartenstein R, 2001, DESIGN AUTOMATION TE; Hauck S, 1998, CAN C FIELD PROGR DE; Itani M, 2004, IEEE ACS INT C PERV; Majzoub S, 2006, IEEE S SIGN PROC INF, P496; Majzoub S, 2003, ACS IEEE INT C COMP; Majzoub S, 2006, 6 INT WORKSH SYST ON; MOLLER L., 2006, P 19 ANN S INT CIRC, P44, DOI 10.1145-1150343.1150360; Nollet V, 2003, P INT C ENG REC SYST, P81; Pan CZ, 2003, DESIGN, AUTOMATION AND TEST IN EUROPE CONFERENCE AND EXHIBITION, PROCEEDINGS, P468; Schneier B., 1996, APPL CRYPTOGRAPHY PR; Schneier B., 1998, TWOFISH 128 BIT BLOC; Singh H, 2000, IEEE T COMPUT, V49, P465, DOI 10.1109-12.8595400
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
