What sorts of cultural criticism are teachers and scholars to produce, and how can that criticism be «employed» in the culture at large? In recent years, debates about the role and direction of English departments have mushroomed into a broader controversy over the public legitimacy of literary criticism. At first glance this might seem odd: few taxpayers and legislators care whether the nation's English professors are doing justice to the project of identifying the beautiful and the sublime. But in the context of the legitimation crisis in American higher education, the image of English departments has in fact played a major role in determining public attitudes toward colleges and college faculty. Similarly, the changing economic conditions of universities have prompted many English professors to rethink their relations to their «clients,» asking how literary study can serve the American public. What sorts of cultural criticism are teachers and scholars to produce, and how can that criticism be «employed» in the culture at large? In The Employment of English, Michael Bérubé, one of our most eloquent and gifted critics, examines the cultural legitimacy of literary study. In witty, engaging prose, Bérubé asserts that we must situate these questions in a context in which nearly half of all college professors are part-time labor and in which English departments are torn between their traditional mission of defining movements of literary history and protocols of textual interpretation, and their newer tasks of interrogating wider systems of signification under rubrics like «gender,» «hegemony,» «rhetoric,» «textuality» (including film and video), and «culture.» Are these new roles a betrayal of the field's founding principles, in effect a short-sighted sell-out of the discipline? Do they represent little more that an attempt to shore up the status of–and student enrollments in–English? Or are they legitimate objects of literary study, in need of public support? Simultaneously investigating the economic and the intellectual ramifications of current debates, The Employment of English provides the clearest and most condensed account of this controversy to date.
An Introduction to Inverse Problems in Physics
An Introduction to Inverse Problems in Physics By (author): M Razavy (University of Alberta, Canada)
This book is a compilation of different methods of formulating and solving inverse problems in physics from classical mechanics to the potentials and nucleus-nucleus scattering. Mathematical proofs are omitted since excellent monographs already exist dealing with these aspects of the inverse problems.
The emphasis here is on finding numerical solutions to complicated equations. A detailed discussion is presented on the use of continued fractional expansion, its power and its limitation as applied to various physical problems. In particular, the inverse problem for discrete form of the wave equation is given a detailed exposition and applied to atomic and nuclear scattering, in the latter for elastic as well as inelastic collision. This technique is also used for inverse problem of geomagnetic induction and one-dimensional electrical conductivity. Among other topics covered are the inverse problem of torsional vibration, and also a chapter on the determination of the motion of a body with reflecting surface from its reflection coefficient.
Introduction to Cellular Biophysics, Volume 2
All living matter is comprised of cells, small compartments isolated from the environment by a cell membrane and filled with concentrated solutions of various organic and inorganic compounds. Some organisms are single-cell, where all life functions are performed by that cell. Others have groups of cells, or organs, specializing in one particular function. The survival of the entire organism depends on all of its cells and organs fulfilling their roles. While the cells are studied by different sciences, they are seen differently by biologists, chemists, or physicists. Biologists concentrate their attention on cell structure and function. What the cells consists of? Where are its organelles? What function each organelle fulfils? From a chemists’ point of view, a cell is a complex chemical reaction chamber where various molecules are synthesized or degraded. The main question is how these, sometimes very complicated chains of reactions are controlled. Finally, from a physics standpoint, some of the fundamental questions are about the physical movement of all these molecules between organelles within the cell, their exchange with the extracellular medium, as well as electrical phenomena resulting from such transport. The aim of this book is to look into the basic physical phenomena occurring in cells. These physical transport processes facilitate chemical reactions in the cell and various electrical effects, and that in turn leads to biological functions necessary for the cell to satisfy its role in the mother organism. Ultimately, the goals of every cell are to stay alive and to fulfill its function as a part of a larger organ or organism. The first volume of this book is an inventory of physical transport processes occurring in cells while this second volume provides a closer look at how complex biological and physiological cell phenomena result from these very basic physical processes.
Measuring Nothing, Repeatedly
There have been many recent discussions of the 'replication crisis' in psychology and other social sciences. This has been attributed, in part, to the fact that researchers hesitate to submit null results and journals fail to publish such results. In this book Allan Franklin and Ronald Laymon analyze what constitutes a null result and present evidence, covering a 400-year history, that null results play significant roles in physics.
The Ringed Planet, Second Edition
On September 15, 2017, the Cassini spacecraft sent its final transmission to the Earth as it entered the atmosphere of Saturn, ending its historic 13 year mission at the ringed planet. This book is a beautifully illustrated journey of discovery through the Saturn system. Cassini's instruments have revealed never seen before details, including the only extraterrestrial lakes known in the solar system, and have provided unprecedented views of the rings, moons, and the planet itself. Results from Cassini's dramatic Grand Finale of ring-grazing and planet-skimming orbits are included in this expanded and updated second edition. Saturn is the jewel of the solar system. The Cassini spacecraft has been exploring the ringed planet and its moons and rings since 2004 and has helped us solve many of its mysteries while generating a wealth of new questions. Cassini has observed the bizarre mountains of Iapetus, the geysers of Enceladus, the lakes of Titan, and the dynamic and evolving rings. Along the way, this book explores and explains the fundamental processes that shape not just the Saturn system, but planets and moons in general. Written for the general audience with an emphasis on the fundamental physics of planetary systems, The Ringed Planet is a fascinating exploration of the Saturn system that places Saturn in the context of the solar system as a whole. Cassini's instruments have revealed Enceladus and Titan to have subsurface oceans of liquid water. Its cameras have returned stunning images of rings in turmoil, a tumbling moon, the only extraterrestrial lakes known in the solar system, a hexagon of clouds, some of the highest mountains in the solar system and much more. More than a journey of discovery at Saturn, The Ringed Planet is also an introduction to how planetary systems work.
Investigative Science Learning Environment
The goal of this book is to introduce a reader to a new philosophy of teaching and learning physics – Investigative Science Learning Environment, or ISLE (pronounced as a small island). ISLE is an example of an «intentional» approach to curriculum design and learning activities (MacMillan and Garrison 1988 A Logical Theory of Teaching: Erotetics and Intentionality). Intentionality means that the process through which the learning occurs is as crucial for learning as the final outcome or learned content. In ISLE, the process through which students learn mirrors the practice of physics.
Mechanics of Biological Systems
This book is an introduction to the mechanical properties, the force generating capacity, and the sensitivity to mechanical cues of the biological system. To understand how these qualities govern many essential biological processes, we also discuss how to measure them. However, before delving into the details and the techniques, we will first learn the operational definitions in mechanics, such as force, stress, elasticity, viscosity and so on. This book will explore the mechanics at three different length scales – molecular, cellular, and tissue levels – sequentially, and discuss the measurement techniques to quantify the intrinsic mechanical properties, force generating capacity, mechanoresponsive processes in the biological systems, and rupture forces.

Run in the Light
Parkinson's disease is a neurological disorder with cardinal motor signs of resting tremor, bradykinesia and lead-pipe rigidity. In addition, many patients display non-motor symptoms, including a diminished sensation of smell, gastrointestinal problems, various disorders of sleep and some cognitive impairment. These clinical features – particularly the motor signs – manifest after a progressive death of many dopaminergic neurones in the brain. Although currently available, conventional therapies can reduce the signs of the disease, the progression of this neuronal death has proved difficult to slow or stop, and the condition is relentlessly progressive. Hence, there is a real need to develop a treatment that is neuroprotective, one that slows the pathology of the disease effectively. At present, there are several neuroprotective therapies in the experimental pipeline, but these are for the patients of tomorrow. This book focuses on two therapies that are readily available for the patients of today. They involve the use of exercise and light (i.e. photobiomodulation, the use of red to infrared light therapy (λ=600-1070nm) on body tissues). The two therapies are tied together in several ways. First, in animal models of Parkinson's disease, they each have been shown to offer the key feature of neuroprotection, stimulating a series of built-in protective mechanisms within the neurones, that helps their survival, to self-protect and/or self-repair. There are also some promising indications of neuroprotection and many beneficial outcomes in parkinsonian patients. Further, both exercise and light therapies are similar in that they are non-invasive and safe to use, with no known adverse side-effects, making their combination with the conventional therapies, such as dopamine replacement drug therapy and deep brain stimulation, all the more feasible. Given the heterogeneity of Parkinson's disease in humans, tackling the condition from a range of different angles – with a number of different therapies – would only serve to enhance the positive outcomes. This book considers the use of exercise and light therapies, proposing that they have the potential to make a powerful «dynamic duo», offering a most effective neuroprotective treatment option to patients.
Outside the Research Lab, Volume 3
The Outside the Research Lab series is a testament to the fact that the physics taught to high school and university students IS used in the real world. This book explores the physics and technology inherent to a selection of sports which have caught the author's attention and fascination over the years. Outside the Research Lab, Volume 3 is a path to discovering how less commonly watched sports use physics to optimize performance, diagnose injuries, and increase access to more competitors. It covers Olympic and Paralympic fencing, show jumping horses, and arguably the most brutal of motorsports – drag racing. Stunning images throughout the book and clear, understandable writing are supplemented by offset detail boxes which take the physics concepts to higher levels. Outside the Research Lab, Volume 3 is both for the general interest reader and students in STEM. Lecturers in university physics, materials science, engineering and other sciences will find this an excellent basis for teaching undergraduate students the range of applications for the physics they are learning. There is a vast range of different areas that require expertise in physics…this third volume of Outside the Research Lab shows a few with great detail provided by professionals doing the work.
