Children are born into a social context that is not of their choosing. From early childhood, this context is made up of diverse group experiences that play a crucial role in shaping a person's social life and desire to learn. This makes the group context an ideal setting for therapeutic and educational work, especially with children and adolescents. This volume offers numerous practical suggestions for using the group as a helpful and supportive medium, e.g., in parent-infant/toddler groups, parent/caregiver groups, groups with children or adolescents, and in preventive group work in schools. The contributions provide insights into the diversity and complexity of conceptual, group analytic w...
This book explores the view that impoverishment and Agree operations are part of a single grammatical component. The architecture set forth here gives rise tocomplex but highly systematic interactions between the two operations. This interaction is shown to provide a unified and general account of apparentlydiverse and unrelated intances of eccentric argument encoding that so far haveremained elusive to a unified theoretical account. The proposed view of the grammatical architecture achieves an integration of these phenomena withinbetter-studied languages and thus gives rise to a more general theory of caseand agreement phenomena. The empirical evidence on the basis of which the proposal is developed drawsfrom a wide range of typologically non-related languages, including Basque, Hindi, Icelandic, Itelmen, Marathi, Nez Perce, Niuean, Punjabi, Sahaptin, Selayarese, Yukaghir, and Yurok . The proposal has far-reaching consequences for the study of grammatical architecture, linguistic interfaces, derivational locality in apparently non-local dependencies and the role of functional considerations in formal approaches tothe human language faculty.
Organic molecules are currently being investigated with regard to their application as active components in semiconductor devices. Whereas devices containing organic molecules for the generation of light - organic light emitting diodes (OLED) - have already reached the market (they e.g. display information on mobile phones), transistors where organic molecules are used to actively control currents and voltages are still in the development stage. In this book the principle problems related to using organic materials as semiconductors and to construct functioning devices will be addressed. A particular emphasis will be put on the difference between inorganic semiconductors such as Si, Ge and GaAs and organic semiconductors (OSC). The special properties of such soft matter require particular approaches for processing characterization and device implementation, which are quite different from the approach used for conventional semiconductors.
This volume presents the results of a multi-year research programme funded by the Deutsche Forschungsgemeinschaft (German Research Council), which explains how organic solar cells work. In this new promising photovoltaic technology, carbon-based materials are deposited by low-cost methods onto flexible substrates, thus allowing devices which open completely new applications like transparent coatings for building, solar cells integrated into clothing or packages, and many more. The investigation of organic solar cells is an interdisciplinary topic, covering physics, chemistry and engineering. The different chapters address topics ranging from the synthesis of new organic materials, to the characterization of the elementary processes such as exciton transport and separation, and the principles of highly efficient device design. /div
The field of organic electronics has seen a steady growth over the last 15 years. At the same time, our scientific understanding of how to achieve optimum device performance has grown, and this book gives an overview of our present-day knowledge of the physics behind organic semiconductor devices. Based on the very successful first edition, the editors have invited top scientists from the US, Japan, and Europe to include the developments from recent years, covering such fundamental issues as: - growth and characterization of thin films of organic semiconductors, - charge transport and photophysical properties of the materials as well as their electronic structure at interfaces, and - analysis and modeling of devices like organic light-emitting diodes or organic lasers. The result is an overview of the field for both readers with basic knowledge and for an application-oriented audience. It thus bridges the gap between textbook knowledge largely based on crystalline molecular solids and those books focusing more on device applications.
In this work nanoscale properties in active layers of small molecule organic solar cells are studied regarding their impact on device performance. For this, the effect of variations in stack design and process conditions is examined both electrically and with high resolution imaging techniques. Two topics are addressed: (i) the visualization of charge extraction/injection properties of solar cell contacts and (ii) the tailoring of structural properties of co-evaporated material blends for bulk heterojunction (BHJ) organic solar cells. (i) We study the impact of controlled contact manipulation on the internal electric potential distribution of fluorinated zincphtalocyanine (F4ZnPc)/fullerene ...
The book addresses a controversial current topic in language acquisition studies: the impact of frequency on linguistic structure in child language. A major strength of the book is that the role of input frequency in the acquisition process is evaluated in a large variety of languages, topics and the two major theoretical frameworks: UG-based and usage-based accounts. While most papers report a clear frequency effect, different factors that may be interacting with pure statistical effects are critically assessed. An introductory statement is made by Thomas Roeper who calls for caution as he identifies frequency as a non-coherent concept and argues for a precise definition of what can and cannot be explained by statistical effects.
This volume showcases a selection of empirical research reports presented at the Experimental Psycholinguistics Conference 2012 held at the National University of Distance Learning in Madrid. It deals with original experimental studies on the processing of language, with special emphasis on word access, word recognition, acquisition of vocabulary, and syntax development in numerous languages, including Brazilian Portuguese, English, German, Polish, Russian, and Spanish, among others.
