Why Do You Ask?: The Function of Questions in Institutional Discourse - Original PDF
نویسندگان: خلاصه: The act of questioning is the primary speech interaction between an institutional speaker and someone outside the institution. These roles dictate their language practices. "Why Do You Ask?" is the first collected volume to focus solely on the question/answer process, drawing on a range of methodological approaches like Conversational Analysis, Discourse Analysis, Discursive Psychology, and Sociolinguistics-and using as data not just medical, legal, and educational environments, but also less-studied institutions like telephone call centers, broadcast journalism (i.e. talk show interviews), academia, and telemarketing. An international roster of well-known contributors addresses such issues as: the relationship between the syntax of the question and its discourse function; the kind of institutional work that questions perform; the degree to which the questioner can control the direction of the conversation; and how questions are used to repackage responses, to construct meaning, and to serve the institutional goals of speakers. Why Do You Ask? will appeal to linguists and others interested in institutional discourse, as well as those interested in the grammatical/pragmatic nature of questions.

Living Better Together Social Relations and Economic Governance in the Work of Ostrom and Zelize - PDF
نویسندگان: خلاصه: olitical economy is a robust field of study that examines the economic and political institutions that shape our interactions with one another. Likewise, social economy focuses on the social interactions, networks, and communities that embody our daily lives. Together, these fields of study seek to understand the historical and contemporary world around us by examining market, political, and social institutions. Through these sectors of life, people come together to exchange goods and services, solve collective problems, and build communities to live better together. Scholarship in this tradition is alive and thriving today. By using the lens of political and social economy, books in this series will examine complex social problems, the institutions that attempt to solve these prob- lems, and the consequences of action within such institutions. Further, this approach lends itself to a variety of methods, including fieldwork, case studies, and experimental economics. Such analysis allows for deeper understanding of social phenomena, detailing the context, incentives, and interactions that shape our lives. This series provides a much-needed space for interdisciplinary research on contemporary topics on political and social economy. In much of academia today, scholars are encouraged to work independently and within the strict boundaries of their disciplines. However, the pursuit of understanding our society requires social scien- tists to collaborate across disciplines, using multiple methods. This series provides such an opportunity for scholars interested in breaking down the boundaries of disciplines in order to better understand the world around us
Laser Application of Polymers - Original PDF
نویسندگان: خلاصه: Abstract Laser ablation of polymers has been studied with designed materials to evaluate the mechanism of ablation and the role of photochemically active groups on the ablation process, and to test possible applications of laser ablation and designed polymers. The incorporation of photochemically active groups lowers the threshold of ablation and allows high-quality structuring without contamination and modification of the remaining surface. The decomposition of the active chromophore takes place during the excitation pulse of the laser and gaseous products are ejected with supersonic velocity. Time-of-flight mass spectrometry reveals that a metastable species is among the products, suggesting that excited electronic states are involved in the ablation process. Experiments with a reference material, i.e., polyimide, for which a photothermal ablation mechanism has been suggested, exhibited pronounced differences. These results strongly suggest that, in case of designed polymers which contain photochemically active groups, a photochemical part in the ablation mechanism cannot be neglected. Various potential applications for laser ablation and the special photopolymers were evaluated and it became clear that the potential of laser ablation and specially designed material is in the field of microstructuring. Laser ablation can be used to fabricate three-dimensional elements, e.g., microoptical elements
Macromolecules Containing Metal and Metal-Like Elements, Transition Metal-Containing Polymers - Original PDF
نویسندگان: خلاصه: Transition metal-containing macromolecules come in a wide variety of structures. While volume 5 of this series dealt with metal coordination polymers, in this book we focus on transition metal-containing polymers where the metal is bonded to at least one organic group through σ- and/or π-bonds. Many of the macromolecules covered in this volume are often referred to as organometallic polymers. The term organometallic compound refers to compounds that contain at least one metal–carbon (M–C) bond, whether the bond is σ or π or some combination of both types of bonding.
Crystallization of polymers. Volume 1, Equilibrium concepts - Original PDF
نویسندگان: خلاصه: Polymers of high molecular weight have now been accepted as respectable members of the molecular community. This situation was not always true.(1) It is now recognized, however, that polymer molecules possess the unique structural feature of being composed of a very large number of chain units that are covalently linked together. This property is common to all macromolecules despite their diverse origin, their widely differing chemical and stereochemical structures and uses and function. It is, therefore, possible to study this class of substances from a unified point of view that encompasses the relatively simpler polymers prepared in the laboratory, as well as the more complex ones of nature. The characteristic thermodynamic, hydrodynamic, physical, and mechanical properties possessed by high polymeric substances can be explained, in the main, by their covalent structure and the attendant large size of the individual molecules.
Synthetic Polymers for Biotechnology and Medicine - Original PDF
نویسندگان: خلاصه: One of the most powerful group of chemicals in the body are organic compounds collectively referred to as hormones. The glands responsible for the production and release of hormones comprise the endocrine system. Endocrine activities have been identified in certain organs, such as the heart, kidneys, duodenum, liver and the islets of Langerhans in the pancreas (which contains the insulin gland), which are normally associated with other system functions. There have been numerous attempts to replace organ function using cell transplantation including direct injections of dissociated cells into organs such as the liver, kidney or spleen.1-5 Subcutaneous and intraperitoneal routes have also been evaluated.6-10 More recent investigations have applied extracellular matrix polymers as structural supports for cell transplantation and immunoprotection.11,12 Potential medical applications of such “artificial cells” or “tissue engineered” organoids include an extracorporeal bioartificial liver for detoxification,2 artificial red blood substitutes,13 the extracorporeal artificial kidney for hemodialysis,14 immunosorbents15 and drug delivery systems.16The transplantation of immunoisolated (microencapsulated) cells represents another emerging area in biotechnology research and commercialization. Under such a scenario, the encapsulated cells, which could be a xenograft, would be hidden from the immune system of the body, but would still be able to respond to extracellular stimuli (e.g., blood glucose), with the required hormone, in the case of diabetes therapy insulin, secreted into the systemic circulation. Other applications of the microencapsulation concept include the encapsulation of genetically modified cells, which represents a novel approach to somatic gene therapy.17 This chapter will review recent advances in cell encapsulation from material science, technological and tissue-related perspectives. Cell coating, microencapsulation devices and bioartificial organs will be discussed with the artificial pancreas and treatment of diabetes used as a case study denominator throughout the review.
