The Subject

Association rule mining is a data mining task that is applied in several real problems. However, due to the huge number of association rules that can be generated, the knowledge post-processing phase becomes very complex and challenging. There are several evaluation measures that can be used in this phase to assist users in finding interesting rules. These measures, which can be divided into data-driven (or objective measures) and user-driven (or subjective measures), are first discussed and then analyzed for their pros and cons. A new methodology that combines them, aiming to use the advantages of each kind of measure and to make user’s participation easier, is presented. In this way, data-driven measures can be used to select some potentially interesting rules for the user’s evaluation. These rules and the knowledge obtained during the evaluation can be used to calculate user-driven measures, which are used to aid the user in identifying interesting rules. In order to identify interesting rules that use our methodology, an approach is described, as well as an exploratory environment and a case study to show that the proposed methodology is feasible. Interesting results were obtained. In the end of the chapter tendencies related to the subject are discussed.

Dialectical Principle

Cognitive Linguistics started from the 1980s, and it has become a mainstream since the end of the last century and the beginning of this century, which has got widespread attention, with a nickname as the third revolution in linguistic circles after the Saussurean Revolution and the Chomskyean Revolution. According to the dialectical principle of “negation of negation”, theoretical research is always advancing, thus the linguists are beginning to think of the shortcomings of Cognitive Linguistics and new developments in the future. For instance, Dabrowska (2016) pointed out the seven deadly sins of Cognitive Linguistics, which, we think, are overstated and too radical. Cognitive Linguistics has its own historical significance and makes great contributions to the criticism of Saussurean “Linguistic Apriorism” and Chomskyean “Linguistic Nativism”, but Cognitive Linguistics also has its own weaknesses, which are to be exposed in brief in this paper. We have also tried to propose “Embodied-Cognitive Linguistics as a revision in order to emphasize the philosophical views of “materialism” and “humanism” as a basic start in linguistic research.

Purpose This study reviews the methods found in the literature for the ranking of authors, identifies the pros and cons of these methods, discusses and compares these methods. The purpose of this paper is to study is to find the challenges and future directions of ranking of academic objects, especially authors, for future researchers. Design/methodology/approach This study reviews the methods found in the literature for the ranking of authors, classifies them into subcategories by studying and analyzing their way of achieving the objectives, discusses and compares them. The data sets used in the literature and the evaluation measures applicable in the domain are also presented. Findings The survey identifies the challenges involved in the field of ranking of authors and future directions. Originality/value To the best of the knowledge, this is the first survey that studies the author ranking problem in detail and classifies them according to their key functionalities, features and way of achieving the objective according to the requirement of the problem.

Heterogeneous catalysts can be of varying complexity ranging from single or double phase systems to complicated mixtures of metals and oxides with additives to help promote chemical reactions, extend the life of the catalysts, prevent poisoning etc. Although catalysis occurs on the surface of most systems, detailed descriptions of the microstructure and chemistry of catalysts can be helpful for developing an understanding of the mechanism by which a catalyst facilitates a reaction. Recent years have seen continued development and improvement of various TEM, STEM and AEM techniques for yielding information on the structure and chemistry of catalysts on the nanometer scale. Here we review some quantitative approaches to catalyst characterization that have resulted from new developments in instrumentation.HREM has been used to examine structural features of catalysts often by employing profile imaging techniques to study atomic details on the surface. Digital recording techniques employing slow-scan CCD cameras have facilitated the use of low-dose imaging in zeolite structure analysis and electron crystallography. Fig. la shows a low-dose image from SSZ-33 zeolite revealing the presence of a stacking fault.

And Function

Despite advances in surgical management, it is estimated that 20–30% of children with repaired cleft palate will continue to have hypernasal speech and require a second surgery to create normal velopharyngeal function (Bricknell, McFadden, & Curran, 2002; Härtel, Karsten, & Gundlach, 1994; McWilliams, 1990). A qualitative perceptual assessment by a speech-language pathologist is considered the most important step of the evaluation for children with resonance disorders (Peterson-Falzone, Hardin-Jones, & Karnell, 2010). Direct and indirect instrumental analyses should be used to confirm or validate the perceptual evaluation of an experienced speech-language pathologist (Paal, Reulbach, Strobel-Schwarthoff, Nkenke, & Schuster, 2005). The purpose of this article is to provide an overview of current instrumental assessment methods used in cleft palate care. Both direct and indirect instrumental procedures will be reviewed with descriptions of the advantages and disadvantages of each. Lastly, new developments for evaluating velopharyngeal structures and function will be provided.

Hematopoetic Stem Cell Transplantation

Die Transplantation hämatopoietischer Stammzellen umfasst heute Stammzellen aus Knochenmark, peripherem Blut oder Nabelschnurblut. Leukämien, Lymphoproliferative Erkrankungen, aplastische Anämie und schwere angeborene Erkrankungen des Knochenmarkes sind Hauptindikationen für allogene, lymphoproliferative Erkrankungen, Leukämien, solide Tumoren und schwere Autoimmunkrankheiten Hauptindikationen für autologe Transplantationen. Neue Verfahren wie reduzierte Konditionierung und selektive Gabe von Spenderlymphozyten eröffnen die Stammzelltransplantation auch für ältere Patienten und für solche mit vorbestehender Komorbidität. Wenn immer möglich, wird die Transplantation ab Diagnose in den Behandlungsplan integriert. Die Wahl des Verfahrens und des geeigneten Zeitpunktes wird nach individuellem Risikoprofil erstellt. Alter oder Diagnose sind nicht mehr alleinige Entscheidungskriterien. Als etablierte Therapieform dürfte die hämatopoietische Stammzelltransplantation als Modell dienen für Stammzelltransplantationen auch anderer Organe.
