From Darwin to Derrida Selfish Genes, Social Selves, and the Meanings of Life - Epub + Converted PDF
نویسندگان: خلاصه: Evolutionary theory can be a nasty business. Perhaps it has something to say about human nature. Most scientifically respectable evolutionary theories wear garments of math. I think of mathematical models as disciplined metaphors. We use x to represent something in the world, say slugs, and y to represent something else, say lettuces, then we analyze the relation of x to y using mathematics. We imagine that slugs and lettuces behave like x and y in the model, and then we use how x and y behave in the model to understand how slugs and lettuces behave in the world. Nobody can argue with mathematical models—that is one of the points of using mathematics—but there can be endless arguments about what you put into a model and what you leave out, and endless arguments about what the model means, because metaphors can be interpreted in many ways. I am not criticizing the use of metaphors—far from it, they are essential. All that we know about the world is metaphor. Our perceptions are a virtual reality, not the thing in itself but something that stands in the place of the thing. Phenomena are metaphors used to comprehend things. Don’t worry, this book contains almost no mathematics; but, if you don’t like metaphor, then this is probably a good time to return the book and ask for a refund.
Game storming by Dave Gray Sunni Brown James Macanufo - Epub + Converted PDF
نویسندگان: خلاصه: Imagine a boy playing with a ball. He kicks the ball against a wall, and the ball bounces back to him. He stops the ball with his foot and kicks it again. By engaging in this kind of play, the boy learns to associate certain movements of his body with the movements of the ball in space. We could call this associative play. Now imagine that the boy is waiting for a friend. The friend appears, and the two boys begin to walk down a sidewalk together, kicking the ball back and forth as they go. Now the play has gained a social dimension; one boy's actions suggest a response, and vice versa. You could think of this form of play as a kind of improvised conversation, where the two boys engage each other using the ball as a medium. This kind of play has no clear beginning or end; rather, it flows seamlessly from one state into another. We could call this streaming play. Now imagine that the boys come to a small park, and that they become bored simply kicking the ball back and forth. One boy says to the other, "Let's take turns trying to hit that tree. You have to kick the ball from behind this line." The boy draws a line by dragging his heel through the dirt. "We'll take turns kicking the ball. Each time you hit the tree you get a point. First one to five wins." The other boy agrees and they begin to play. Now the play has become a game; a fundamentally different kind of play. What makes a game different? We can break down this very simple game into some basic components that separate it from other kinds of play.Imagine a boy playing with a ball.

Imagining Prostitution in Modern Japan, 1850–1913 - PDF
نویسندگان: خلاصه: 1 O ne Introduction On a mid-winter morning, some months after the death of the Meiji Em- peror on July 30, 1912, daily newspapers across Japan informed the na- tion that an “unprecedented manuscript,” written by a prostitute under the pseudonym Wada Yoshiko, was arriving at bookstores everywhere. It was called Yūjo monogatari (A Prostitute’s Tale) and was published by Bunmeidō Press.1 The news of Wada’s accomplishment was so wide- spread that for the rest of the week, it attracted an unusual procession of visitors to her pleasure quarters in Naitō-Shinjuku, a famous commuter town located on the outskirts of Tokyo. Journalists lined up to interview her, current patrons came to congratulate her, and new potential clients showed up to set eyes on her.2 In her sequel, Yūjo monogatari, zoku-hen (A Prostitute’s Tale, Part II), published less than a year after the first book, Wada describes this mo- ment as a set of mixed blessings (see figure 1.1). At first, she encountered unrelenting scorn and criticism from her immediate circle of managers, colleagues, and patrons. After the book was released, the madam of the brothel harshly condemned her for divulging private information about their clients. Her book revealed unsavory details about the conditions of the syphilis hospital where the prostitutes went for regular mandatory health exams and were confined if found diseased. Given her negative exposé, the director of the hospital came to the brothel to denounce Wada for staining his good reputation. Although Wada was careful not to reveal any names, she had disclosed job titles, and therefore, the madam rea- soned, anyone could identify the director or other brothel affiliates men- tioned in her book. In response, the madam demanded that Wada issue an immediate apology and retract some of the sections of her publication. Prostitutes in the brothel shunned Wada, too, for sharing details about their district clients and destroying their mutual trust.
Integral Waterproofing of Concrete Structures - Original PDF
نویسندگان: خلاصه: Concrete is the most popular construction material, which has a widespread range of structural applications, under numerous environmental conditions and under various levels and types of mechanical loads. It is used in buildings, infrastruc- tures, dams etc. Its suitability and durability require a set of mechanical, physi- cal, and chemical characteristics in order to extend its service life. Concrete durability is defined according to Concrete Terminology by American Concrete Institute (ACI) [1], as “the ability of concrete to resist weathering action, chemi- cal attack, abrasion, and other conditions of service.” This performance is simply based on concrete chemistry. Concrete durability properties are determined by its chemical structure and porosity. These structural characteristics are determined by cement components and their reactions with water. Understanding concrete durability problems and solutions requires a sufficient knowledge about concrete chemistry.
Iron Oxides by Damien Faivre - PDF
نویسندگان: خلاصه: As the name of the book “Iron oxides: from nature to applications” suggests, iron oxides are not only widespread in the environment, but also widely used by mankind in a variety of applications (Figure 1.1). Both this ubiquitous presence in nature and the utilization as tools have been established for cen- turies and are still valid today. The first illustrative examples of iron oxides certainly are compass needle or rust (Figure 1.2). Iron oxides are present in solid, liquid, and gaseous environments, with respective examples such as rocks, as mineral inclusion in swimming bacteria or in aerosols. Depending on the type of use, several sources of iron oxides exist. Applications range from the heavy steel production to medicine and art. The different aspects of mineral formation and their use as well as modern characterization techniques are reviewed in this book
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 elementsآیا 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.
