Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
In the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)

Dispelling the Myths Behind First-author Citation Counts
We 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
RESULTS OF TWO CASES WITH DISTINCT COMPLICATIONS DUE TO INTRAVITREAL BEVACIZUMAB IN RETINOPATHY OF PREMATURITY
Purpose:To present the surgical outcome and long-term follow-up of 2 cases who underwent intravitreal bevacizumab injection for retinopathy of prematurity (ROP) and subsequently developed full thickness macular hole and endophthalmitis.Methods:Case report.Patients:The first case is a premature girl who was delivered 650 g at the 27th week of postmenstrual age (PMA) because of preeclampsia and received intravitreal 0.16 mg bevacizumab bilaterally at the 38th PMA with the diagnosis of ROP. She was referred with endophthalmitis 10 days after injection in the left eye. Endophthalmitis resolved with pars plana vitrectomy that was performed the following day. The second case is a premature girl who was delivered at the 30th week of PMA weighing 1,230 g and received intravitreal 0.16 mg bevacizumab injections bilaterally at the 39th PMA with a diagnosis of ROP. Retinopathy of prematurity regressed in the follow-up; however, full thickness macular hole was noted in the right eye on the first week of the injection. Pars plana vitrectomy, internal limiting membrane peeling, and gas tamponade were performed at the 41st PMA week. Full thickness macular hole persisted despite pars plana vitrectomy whereas glaucoma emerged during the follow-up.Conclusion:Development of endophthalmitis and macular hole may occur after intravitreal injections in cases with ROP

Comprehension, Use Cases and Requirements
Within requirements engineering it is generally accepted that in writing specifications (or indeed any requirements phase document), one attempts to produce an artefact which will be simple to comprehend for the user. That is, whether the document is intended for customers to validate requirements, or engineers to understand what the design must deliver, comprehension is an important goal for the author. Indeed, advice on producing ‘readable’ or ‘understandable’ documents is often included in courses on requirements engineering. However, few researchers, particularly within the software engineering domain, have attempted either to define or to understand the nature of comprehension and it’s implications for guidance on the production of quality requirements.
In contrast, this paper examines thoroughly the nature of textual comprehension, drawing heavily from research in discourse process, and suggests some implications for requirements (and other) software documentation. In essence, we find that the guidance on writing requirements, often prevalent within software engineering, may be based upon assumptions which are an oversimplification of the nature of comprehension. Furthermore, that these assumptions may lead to rules which detract from the quality of the requirements document and, thus, the understanding gained by the reader. Finally the paper suggests lessons learned which may be useful in formulating future guidance for the production of requirements documentation
The Göttingen rotating turbulent Rayleigh-Bénard convection facility
Thermally driven turbulent convection under the influence of global rotation is ubiquitous in nature. Well known examples are the outer convective shell of our Sun and the outer liquid core of the Earth. Trying to understand the underlying dynamics of such flows is highly challenging, not only because of the enormous range in length- and time-scales that are involved with these geo/astrophysical cases and the complex interaction of hydrodynamics with electromagnetism, but also because direct measurements on these systems are most often impossible to carry out. We gain access to direct measurements by isolating part of the problem: We focus solely on the hydrodynamical aspects of turbulent convection by performing experiments in the lab and making comparisons with direct numerical simulations (DNS). The canonical system that we use to study such flows is Rayleigh-B\'enard convection (RBC), the flow between a warm bottom plate and cold top plate, in a fluid-filled upright cylindrical cell that is rotating around its geometrical axis. This presentation will focus on the newly constructed rotating RBC facility at the Max Planck Institute for Dynamics and Self-Organization (MPIDS) in G\"ottingen
