Handbook of Research on Promoting Higher- Order Skills and Global Competencies in Life and Work - Original PDF
نویسندگان: خلاصه: ABSTRACT Critical thinking and other higher-order thinking skills are key objectives of higher education. Through the development of higher-order thinking skills, students are able to discern information from multiple, often competing sources, make sound judgements, draw conclusions, and enact creative solutions to complex problems. However, faculty can struggle with how to help students develop higher-order think- ing skills, relying instead on transmission of knowledge, focusing on what to learn instead of how to learn. In this chapter, the author provides insights into the connections between using gamification as a pedagogical approach, and the development of higher-order thinking skills. The chapter addresses perspectives on higher-ordering thinking, approaches to gamification in college courses, and concludes with recommendations for faculty in approaching gamification
Statistics for Business & Economics by David_R_Anderson,_Dennis_J_Sweeney - Original PDF
نویسندگان: خلاصه: This text is the 14th edition of STATISTICS FOR BUSINESS AND ECONOMICS. In this edition, we include procedures for statistical analysis using Excel 2016 and JMP Student Edition 14. In MindTap Reader, we also include instructions for using the exceptionally popular open-source language R to perform statistical analysis. We are excited to introduce two new coauthors, Michael J. Fry of the University of Cincinnati and Jeffrey W. Ohlmann of the University of Iowa. Both are accomplished teachers and researchers. More details on their backgrounds may be found in the About the Authors section. The remainder of this preface describes the authors’ objectives in writing STATISTICS FOR BUSINESS AND ECONOMICS and the major changes that were made in developing the 14th edition. The purpose of the text is to give students, primarily those in the fields of business administration and economics, a conceptual introduction to the field of statistics and its many applications. The text is applications-oriented and written with the needs of the nonmathematician in mind; the mathematical prerequisite is understanding of algebra. Applications of data analysis and statistical methodology are an integral part of the or- ganization and presentation of the text material. The discussion and development of each technique is presented in an application setting, with the statistical results providing insights to decisions and solutions to problems. Although the book is applications oriented, we have taken care to provide sound meth- odological development and to use notation that is generally accepted for the topic being covered. Hence, students will find that this text provides good preparation for the study of more advanced statistical material. A bibliography to guide further study is included as an appendix
Darwin and Catholicism BY Caruana - Original PDF
نویسندگان: خلاصه: Charles Darwin (1809–82) explained the history and variety of life on earth in terms of evolution. He formulated his ideas for the first time in his book On the Origin of Species, published in 1859. His theory brought together under one explanation the innumerable different phe- nomena observable in the organic world, and suggested moreover that the difference between humans and non-human animals was a difference in degree rather than one of kind.1 Because of this, philosophical and theological debates soon became inevitable. What had been formulated as a new scientific theory quickly developed into a new philosophical and cultural paradigm with repercussions in ethics, anthropology and theology.

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
Absorbable biodegradable polymers - Original PDF
نویسندگان: خلاصه: Egyptians sutured wounds as early as 3500 B.C. using a variety of natural polymers including treated intestines, which are the early versions of collagen-based surgical gut sutures.1 Synthetic, absorbable polyesters based on 2-hydroxyacetic acids were developed for preparing less tissue reactive alternatives to surgical gut sutures in the early 1970s. In addition to collagenbased polymers, other natural, absorbable polymers, such as albumin, chitosan, and hyaluronic acid and derivatives thereof have been used for many pharmaceutical and biomedical applications for several decades.2 Of these polymers, the application of chitosan and hyaluronic acid–based polymers has received a great deal of attention in the past 15 years for use in controlled drug delivery systems, tissue repair, tissue engineering, and controlling certain biological events.
Coatings Of Polymers And Plastics - Original PDF
نویسندگان: خلاصه: Human development is clearly linked to continuous improvements in the materials used every day. Entire stages of history have been named after the critical materials—Stone Age, Bronze Age, Iron Age, and now, the Age of Plastics. When asked his opinion on chemistry’s largest contribution to science and society, Lord Todd, the President of the Royal Society of London, responded: “I am inclined to think that the development of polymerization is, perhaps, the biggest thing chemistry has done, where it has had the biggest effect on everyday life. The world would be a totally different place without artificial fibers, plastics, elastomers,
Handbook of Biodegradable Polymers - Original PDF
نویسندگان: خلاصه: Biodegradable polymers are niche market materials finding focused applications, including agricultural applications such as mulch films, flowerpots and controlled-release fertilisers and packaging items such as carrier bags and food wrapping and containers. They have the potential to provide a solution to a range of environmental concerns: decreasing availability of landfill space, declining petrochemical sources, and also offer an alternative option to recycling. Rapra's Handbook of Biodegradable Polymers is a complete guide to the subject of biodegradable polymers and is ideal for those new to the subject or those wanting to supplement their existing knowledge. The book covers the mechanisms of degradation in various environments, by both biological and non-biological means, and the methods for measuring biodegradation. The degree and rate of biodegradation is dependent on the chemical composition of the polymer and its working environment, and so there is no single optimal method for determining biodegradation. This handbook provides discussion of international and national standards and certification procedures developed to ensure accurate communication of a material's biodegradability between producers, authorities and consumers. The book goes on to consider the characteristics, processability and application areas for biodegradable polymers, with key polymer family groups discussed.
Liquid Crystalline Polymers - Original PDF
نویسندگان: خلاصه: As we know, there are three basic states of matter, solid, liquid, and gaseous states. These states of matter can be transformed into each other at appropriate conditions. In the solid state (generally meaning the crystalline state), the building blocks, such as atoms, or molecules, or clusters of molecules are packed closely and regularly, forming a crystal lattice. The X-ray diffraction of the state shows many regular diffraction spots. Over 95% of matter on the earth exist in the form of the crystalline state. The types of crystal structure are enormous. The physical properties of crystals are basically anisotropic. The crystals have a constant melting temperature (except for amorphous solids).
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.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
