Free Download When Women Were Birds: Fifty-four Variations on Voice By Terry Tempest Williams
2012 | 224 Pages | ISBN: 0374288976 | EPUB | 1 MB
The beloved author of Refuge returns with a work that explodes and startles, illuminates and celebratesTerry Tempest Williams’s mother told her:"I am leaving you all my journals, but you must promise me you won’t look at them until after I’m gone."Readers of Williams’s iconic and unconventional memoir, Refuge, well remember that mother.She was one of a large Mormon clan in northern Utah who developed cancer as a result of the nuclear testing in nearby Nevada. It was a shock to Williams to discover thather mother had kept journals.But not as much of a shock as what she found when the time came to read them."They were exactly where she said they would be: three shelves of beautiful cloth-bound books . . . I opened the first journal.It was empty. I opened the second journal.It was empty.I opened the third.It too was empty . . . Shelf after shelf after shelf, all of my mother’s journals were blank." What did Williams’s mother mean by that? Infifty-four chapters that unfold like a series of yoga poses, each with its own logic and beauty, Williams creates a lyrical and caring meditation of the mystery of her mother’s journals. When Women Were Birds is a kaleidoscope that keeps turning around the question "What does it mean to have avoice?" Note: blank pages are intentional.

Teaching About Dialect Variations and Language in Secondary English Classrooms

English | ISBN: 041581846X | 2014 | 224 pages | EPUB, PDF | 2 MB + 1187 KB
Standardized tests demand Standard English, but secondary students (grades 6-12) come to school speaking a variety of dialects and languages, thus creating a conflict between students’ language of nurture and the expectations of school. The purpose of this text is twofold: to explain and illustrate how language varieties function in the classroom and in students’ lives and to detail linguistically informed instructional strategies. Through anecdotes from the classroom, lesson plans, and accessible narrative, it introduces theory and clearly builds the bridge to daily classroom practices that respect students’ language varieties and use those varieties as strengths upon which secondary English teachers can build. The book explains how to teach about language variations and ideologies in the classroom; uses typically taught texts as models for exploring how power, society, and identity interact with language, literature, and students’ lives; connects the Common Core State Standards to the concepts presented; and offers strategies to teach the sense and structure of Standard English and other language variations, so that all students may add Standard English to their linguistic toolboxes.

Euphorias in Gender, Sex and Sexuality Variations Positive Experiences


Free Download Tiffany Jones, "Euphorias in Gender, Sex and Sexuality Variations: Positive Experiences"
English | ISBN: 3031237552 | 2023 | 217 pages | PDF | 6 MB
This Open Access book uses the concept of ‘euphoria’ to investigate when, why and how marginal gender, sex and sexuality groups have positive experiences of their diverse variations even within repressive and disordering contexts. Drawing on data from multiple online surveys including a study of 2,407 LGBTQ+ people and a study of 272 people with intersex variations, it names and offers a new ecological framework for understanding participants’ influences on and barriers to euphorias, asserting the subversive possibilities of being euphorically queer, as opposed to euphoric and queer. The author argues that it is the particularities of negative internal, socio-cultural and institutional contexts for a marginal group or groups that contributes towards the possibilities that shape their potential euphoric feelings and experiences. Ultimately, she calls for a more expansive focus in gender and sexuality studies to show the complex effects of dysphoria and repression on the possibilities of pleasure and joy.

Different Faces of Attachment Cultural Variations on a Universal Human Need


Free Download Hiltrud Otto, "Different Faces of Attachment: Cultural Variations on a Universal Human Need"
English | ISBN: 1107027748 | 2014 | 338 pages | PDF | 4 MB
Attachment between an infant and his or her parents is a major topic within developmental psychology. An increasing number of psychologists, evolutionary biologists and anthropologists are articulating their doubts that attachment theory in its present form is applicable worldwide, without, however, denying that the development of attachment is a universal need. This book brings together leading scholars from psychology, anthropology and related fields to reformulate attachment theory in order to fit the cultural realities of our world. Contributions are based on empirical research and observation in a variety of cultural contexts. They are complemented by careful evaluation and deconstruction of many of the underlying premises and assumptions of attachment theory and of conventional research on the role of infant-parent attachment in human development. The book creates a contextual cultural understanding of attachment that will provide the basis for a groundbreaking reconceptualization of attachment theory.

Calculus of Variations (Dover Books on Mathematics)


Free Download I. M. Gelfand, S. V. Fomin, "Calculus of Variations (Dover Books on Mathematics)"
English | 2000 | pages: 256 | ISBN: 0486414485, 0131122924 | EPUB | 17,8 mb
Based on a series of lectures given by I. M. Gelfand at Moscow State University, this book actually goes considerably beyond the material presented in the lectures. The aim is to give a treatment of the elements of the calculus of variations in a form both easily understandable and sufficiently modern. Considerable attention is devoted to physical applications of variational methods, e.g., canonical equations, variational principles of mechanics, and conservation laws.

A Course in the Calculus of Variations


Free Download A Course in the Calculus of Variations
English | 2023 | ISBN: 3031450353 | 338 Pages | PDF EPUB (True) | 32 MB
Beginning with the scientific modeling that motivates the subject, the book then tackles mathematical questions such as the existence and uniqueness of solutions, their characterization in terms of partial differential equations, and their regularity. It includes both classical and recent results on one-dimensional variational problems, as well as the adaptation to the multi-dimensional case. Here, convexity plays an important role in establishing semi-continuity results and connections with techniques from optimization, and convex duality is even used to produce regularity results. This is then followed by the more classical Hölder regularity theory for elliptic PDEs and some geometric variational problems on sets, including the isoperimetric inequality and the Steiner tree problem. The book concludes with a chapter on the limits of sequences of variational problems, expressed in terms of Γ-convergence.

Selected Chapters in the Calculus of Variations


Free Download Selected Chapters in the Calculus of Variations by Jürgen Moser , Oliver Knill
English | PDF (True) | 2003 | 139 Pages | ISBN : 3764321857 | 9 MB
0.1 Introduction These lecture notes describe a new development in the calculus of variations which is called Aubry-Mather-Theory. The starting point for the theoretical physicist Aubry was a model for the descrip tion of the motion of electrons in a two-dimensional crystal. Aubry investigated a related discrete variational problem and the corresponding minimal solutions. On the other hand, Mather started with a specific class of area-preserving annulus mappings, the so-called monotone twist maps. These maps appear in mechanics as Poincare maps. Such maps were studied by Birkhoff during the 1920s in several papers. In 1982, Mather succeeded to make essential progress in this field and to prove the existence of a class of closed invariant subsets which are now called Mather sets. His existence theorem is based again on a variational principle. Although these two investigations have different motivations, they are closely re lated and have the same mathematical foundation. We will not follow those ap proaches but will make a connection to classical results of Jacobi, Legendre, Weier strass and others from the 19th century. Therefore in Chapter I, we will put together the results of the classical theory which are the most important for us. The notion of extremal fields will be most relevant. In Chapter II we will investigate variational problems on the 2-dimensional torus. We will look at the corresponding global minimals as well as at the relation be tween minimals and extremal fields. In this way, we will be led to Mather sets.
