A Linguistic History of Italian offers a clear and concise explanation of why modern Italian grammar has become the way it is. It focuses on the effects of historical changes on the modern structure of Italian, revealing patterns and structures which are not always apparent to those who are only familiar with modern Italian. Although the book concentrates on the internal history of the language, the emergence of Italian is considered against the wider background of the history of italian dialects, and other external factors such as cultural and social influences are also examined.

From the Preface This book is the first extended look at a new and multifaceted polymer processing technology that has already been discussed in numerous articles. Called Solid-State Shear Pulverization (S3P), this innovative process produces polymeric powders with unique physical properties not found in the output of conventional size-reduction methods.... This technology, which utilizes a pulverizer based on a modified co-rotating twin-screw extruder..., has profound implications for both the creation of new polymer blends and recycling of plastic and rubber waste. Unlike [earlier processes] where polymers are melted prior to pulverization, ...pulverizing mixtures of polymers with the S3P process...does not involve melting. By contrast, S3P maintains polymers in the solid state and avoids the additional heat history that occurs during [other processes], which can be detrimental to the physical properties of pulverized materials. The research and development of the S3P technology...has grown significantly since 1990 from the development of a new plastics recycling process to a much broader polymer processing method that allows intimate mixing of polymers with very different viscosities, sold-state dispersion of additives, including pigments, and continuous production of powder with unique shapes and larger surface areas. Polymeric powders are of growing importance to plastics processors due to the increase use of plastics in various applications, such as rotational molding, powder coatings, and compounding, which require powder as the feedstock. ...[I]t has become clear that this process allows for in-situ compatibilization of dissimilar polymers by applying mechanical energy to cause chemical reactions. This aspect of S3P technology that we describe in this book should [be useful in] developing new polymer blends with the use of pre-made compatibilizing agents. In addition, it has been discovered that S3P efficiently mixes polymer blends with different component viscosities, resulting in the elimination of phase inversion. The S3P process directly produces blends with matrix and dispersed phase morphology like those obtained after phase inversion during a long melt-mixing process. This phenomenon is of practical importance because a long processing time is required by conventional melt-mixing to produce a stable blend morphology. S3P is also advantageous for producing thermoplastic or thermoset powder-coating compounds in a one-step process as opposed to a conventional multi-step operation that involves melt extrusion followed by batch grinding. The major capabilities of this new process can be summarized as follows: o Continuous powder production from plastics or rubber feedstocks o Blending of immiscible polymers o Efficient mixing of polymers with unmatched viscosities o Environmentally friendly recycling of multicolored, commingled plastics waste o Sold-state dispersion of heat-sensitive additives o Engineered plastic/rubber blends Materials and processes well illustrated The text is well illustrated with 60 photographs, micrographs, diagrams and others figures. Here is a small sampling of the captions of these figures. o Particle-size distribution for virgin LDPE powder made with PT-25 pulverizer o Optical photograph of virgin LDPE powder made with PT-25 pulverizer o Layout for a three-stage rubber pulverizer o Flow chart for powder coating production by conventional process and with new S3P technology o SEM image of pulverized virgin PP at 40X (first in series of SEM images of polymer powders) o Optical micrograph of melt-crystallized thin films of unpulverized virgin PP under polarized light o Log of viscosity vs. log shear rate for virgin HDPE after S3P processing o Gel permeation chromatograms (GPC) of polystyrene subjected to S3P processing Color-photo section One of the several functions of Solid-State Shear Pulverization technology is recycling mixed plastic waste. This section of twenty full-color photographs and micrographs illustrates different processed materials, as well as the machinery and mixed waste used. Here is a small sampling of the photo and micrograph captions. o Resultant flake feedstock from granulation o S3P-made uniform powder from feedstock o Flake feedstock of post-consumer HDPE/PP blend (90/10 ratio) o Injection-molded test bar (with translucence) made from S3P powder without pelletization o Injection-molded test bar made from S3P powder without pelletization showing uniform color o Several test bars subjected to tensile testing showing exceptionally high elongation at break Useful reference data in tables More than 60 tables provide useful data in convenient form. Here is a small sampling of table captions. o Physical properties of virgin PP 8020 GU injection-molded from S3P-made powder (first in series of tables on physical properties of various plastics processed from S3P-made powder) o Sieve analysis of powder resulting from S3P of virgin LDPE 509.48 (one of series of tables on sieve analysis of polymer powders) o Melt-flow rate before and after S3P processing for virgin PS and two PP samples o Key physical properties of injection-molded post-consumer polyolefin blends pulverized by S3P process The Authors Klementina Khait, M.S.

Writing development is currently the focus of substantial international debate because it is the aspect of literacy education that has been least responsive to central government and state reforms. Teaching approaches in writing have been slower to change than those in teaching reading and pupil attainment in writing has increased at a much more modest rate than pupil attainment in reading. This handbook critically examines research and theoretical issues that impact on writing development from the early years through to adulthood. It provides those researching or teaching literacy with one of the most academically authoritative and comprehensive works in the field. With expert contributors from across the world, the book represents a detailed and valuable overview of a complex area of study.
If there is a single rallying claim in the many recent discussions of the future of
reading and writing, it is, as Naomi Baron phrases it in her essay, 'The Future of
Written Culture: Envisioning Language in the New Millennium', that 'the computer

Das Gesundheitswesen unterliegt permanent komplexeren Veränderungen und ist durch Kerntrends gekennzeichnet. Diese Dynamik erfordert, dass Krankenhäuser strategisch handeln, die Veränderungen bzw. Wandel erkennen und die Tendenzen nutzen, um weiterhin ihre Wettbewerbsvorteile zu sichern. Aktuell sind deutsche Krankenhäuser gezwungen mit knappen Ressourcen ihre Wettbewerbsfähigkeit zu sichern. Der zukünftige Trend auf dem Krankenhaussektor liegt in der Leistungstransparenz, Konsumentensouveränität und Überschuss an Angeboten. Daraus folgt, dass die deutschen Krankenhäuser ihre Wettbewerbsfähigkeit langfristig nur sichern können, wenn sie eine strategische Ausrichtung und operative Umsetzung von geeigneten Maßnahmen nachhaltig in das Unternehmen implementieren und durch optimale Instrumente ergänzen Die früher geltenden zentralistischen Steuerungsprinzipien wie zum Beispiel die Überdeckung von ineffizienten Vorgängen durch Überkapazitäten und die Vereinbarungen von Bedarfsnotwendigkeiten mittels regelmäßigen Subventionen der deutschen Krankenhäuser existieren nicht mehr. Vor dem Hintergrund der Veränderungen auf dem Gesundheitssektor und daraus resultierende Notwendigkeit, das Krankenhaus als Unternehmen in einem verstärkten Wettbewerbsumfeld zu betrachten werden zunächst die Erfolgsfaktoren eines exzellenten Krankenhauses identifiziert, um daraus ableitend die Strategien sowie Instrumente entwickeln zu können. Im Kontext eines erfolgreichen Unternehmens wird die Balanced Scorecard als ein Managementkonzept dargestellt und seine vier Perspektiven skizziert. Darauf folgt die Umsetzung der Balanced Scorecard auf ein fiktives Unternehmen Krankenhaus, dabei werden detaillierte Kennzahlen aus dem Krankenhaussektor herangezogen. Mögliche Risiken bei der Verwendung der Balanced Scorecard im Krankenhaus wie zum Beispiel die Fehlsteuerung aufgrund der Komplexität des Konzepts werden dargestellt. Im Rahmen dieser Arbeit soll die Steigerung der Wettbewerbsfähigkeit im Krankenhauswesen durch die Implementierung von Balanced Scorecard anhand von Fallbeispielen kritisch betrachtet werden. Dabei werden die Anforderungen an die erfolgreiche Einführung der Balanced Scorecard skizziert und Chancen für die Krankenhäuser bezüglich des steigenden Wettbewerbsdrucks unter den aktuellen gesetzlichen Rahmenbedingungen dargestellt.
Dabei wird detailliert auf alle vier Perspektiven der Balanced Scorecard im
Kontext eines Krankenhausmanagements anhand eines fiktiven Beispiels
eingegangen. Bevor sich diese Arbeit den vier Perspektiven der Balanced
Scorecard ...
