This report defines Overhead Contact Systems (OCSs) and describes the function of OCSs for trolleybus and light rail systems. The report describes nonintrusive and intrusive designs, considering the overall visual impact of those designs on intersections or street segments and the complete effect that hardware has in any given location. It discusses the influence system design has on visual impact including the need for emergency wire and the use of one-way operation to minimize visual impact in trolleybus systems. Further, it investigates how the turning capability in trolleybus and light rail OCS design may have an effect on visual impact. The report considers the effect of curve design and the design of the electrical distribution systems on the appearance of light rail. An approach to evaluating the visual impact of trolleybus intersections is presented. This report concludes that the visual impact of OCSs can only be reduced if such reduction is made a specific goal throughout the design process.
This thoughtful book offers a widely accessible account of the recent economic collapse and crisis, emphasizing the deep nexus of economic inequality, undemocratic power, and leave-it-to-the-market ideology at its root. Based on their understanding of the origins of the crisis, the authors propose a program for reform that is equally dependent on poppular action and changes in government policy.
Many communities across the nation still lack affordable housing. And many officials continue to claim that “affordable housing” is an oxymoron. Building inexpensively is impossible, they say, because there are too many regulations. Required environmental impact statements and habitat protection laws, they contend, drive up the costs of construction. But is this actually true? In a comprehensive study of the question, the authors of this eye-opening book separate fact from myth. With admirable clarity, they describe the policy debate from its beginning, review the economic theory, trace the evolution of development regulation, and summarize the major research on the topic. In addition, they offer their own research, accompanied by a case study of two strikingly different Washington, D.C., suburbs. They also include results of focus groups conducted in Dallas, Denver, and Tucson. The authors find that environmental regulatory costs—as a share of total costs and processes—are about the same now as they were thirty years ago, even though there are far more regulations today. They find, too, that environmental regulations may actually create benefits that could improve the value of housing. Although they conclude that regulations do not appear to drive up housing costs more now than in the past, they do offer recommendations of ways in which the processes associated with regulations—including review procedures—could be improved and could result in cost savings. Intended primarily for professionals who are involved in, or impacted by, regulations—from public officials, planners, and engineers to housing developers and community activists—this book will provide useful insights and data to anyone who wants to know if (and how) American housing can actually be made “affordable.”
The evil prosthesis of Captain Hook, the comical speech of Porky Pig, and the bumbling antics of Mr. Magoo are all examples of images in our culture which can become the basis of negative attitudes and subliminal prejudice towards persons with disabilities. These attitudes influence and underlie discriminatory acts, resulting in negative treatment and segregation. A teacher's ability to recognize and counter such images may well determine the success of inclusion and mainstreaming programs in our schools and society. Well-researched and well-written, this book offers practical guidance as grounded in solid research to schools that are wrestling with how to mainstream children with disabilities.
In this book on Fundamentals of Mass Determination, the definition and dissemination of units of mass is explained, starting with an introduction to metrology and mass determination. Establishing a mass scale requires corresponding mass standards and mass comparators. The metrological requirements for weighing instruments, weight pieces, and measuring conditions are explained and discussed based on international directives and applicable legal regulations. International directives and institutions are striving towards the worldwide uniform implementation of these requirements. Processes used to determine density and volume are described to the extent that they apply to mass determination. Calculating measurement uncertainty entails taking into consideration the effect of influence variables on mass determination. An overview of this topic is provided to make it easier to determine and specify measurement uncertainty in practice, while additional information in the form of tables, illustrations, and literature references allow the reader to study mass metrology further.
This book presents a string-theoretic approach to new ideas in particle physics, also known as Physics Beyond the Standard Model, and to cosmology. The concept of Naturalness and its apparent violation by the low electroweak scale and the small cosmological constant is emphasized. It is shown that string theory, through its multitude of solutions, known as the landscape, offers a partial resolution to these naturalness problems as well as suggesting more speculative possibilities like that of a multiverse. The book is based on a one-semester course, as such, it has a pedagogical approach, is self-contained and includes many exercises with solutions. Notably, the basics of string theory are introduced as part of the lectures. These notes are aimed at graduate students with a solid background in quantum field theory, as well as at young researchers from theoretical particle physics to mathematical physics. This text also benefits students who are in the process of studying string theory at a deeper level. In this case, the volume serves as additional reading beyond a formal string theory course.
In Transforming Troubled Children, Teens, and Their Families: An Internal Family Systems Model for Healing, Dr. Mones presents the first comprehensive application of the Internal Family Systems (IFS) Therapy model for work with youngsters and their families. This model centers diagnosis and treatment around the concept of the Functional Hypothesis, which views symptoms as adaptive and survivalbased when viewed in multiple contexts. The book provides a map to help clinicians understand a child’s problems amidst the reactivity of parents and siblings, and to formulate effective treatment strategies that flow directly from this understanding. This is a nonpathologizing systems and contextual approach that brings forward the natural healing capacity within clients. Dr. Mones also shows how a therapist can open the emotional system of a family so that parents can let go of their agendas with their children and interact in a loving, healthy, Self-led way. This integrative MetaModel combines wisdom from Psychodynamic, Structural, Bowenian, Strategic, Sensorimotor, and Solution-Focused models interwoven with IFS Therapy. A glossary of terms is provided to help readers with concepts unique to IFS. Unique to this approach is the emphasis on shifting back and forth between intrapsychic and relational levels of experience. Therapy vignettes are explored to help therapists address issues such as trauma, anxiety, depression, somatization, oppositional and self-destructive behavior in children, along with undercurrents of attachment injury. Two detailed cases are followed over a full course of treatment. A section on Frequently Asked Questions explores work with families of separation and divorce, resistance, the trajectory of treatment, dealing with anger, linking to twelve-step programs, and much more. This is an ideal book for any therapist in quest of understanding the essence of healing and seeking therapeutic strategies applied within a compassionate framework.
We know a lot about innovation in education--when it occurs, what forms it takes, or what steps it involves. But we don't know why it fails or succeeds. Arthur Levine's goal in writing this book was to understand how change can be accomplished successfully. His focus is on what happens after a change has been adopted. Levine first offers a theory about change in organizations, based on the personality of the organization. He then examines his theory of change in a detailed study of fourteen structurally similar innovations in the experimental colleges at the State University of New York at Buffalo. He concludes with a review of other studies of universities as organizations in general, integrating his theory with other research on innovation in organizations.
Dr. Arthur Mones reflects on a 45-year career in psychotherapy and points out what has worked and what mistakes he’s made to provide guidance for new and seasoned practitioners. Dr. Mones traces his own career development in parallel with the historical changes in psychotherapy. The reader is introduced to the Internal Family Systems (IFS) orientation that guides Dr. Mones’ practice and learns how this system can be applied to conceptualize client symptomology from an adaptive strength-based framework to help clients experience improved mental health. Case examples illustrate the use of IFS as a practical treatment for a variety of psychiatric disorders. Callout text, illustrated notation, guided exercises and questions, and defined terms make the text interactive and engaging, making the book suitable for use as a teaching aide in a class, for practitioners to learn a new approach to family therapy, for those interested in learning more about their own mental health and useful strategies to improve functioning, or for clinicians to find companionship in the wisdom, wit, and insightful reflections of Dr. Mones on his academic, clinical, and personal growth in the field of psychotherapy. The book traces the history of family therapy. It starts with its multidisciplinary origins in systems theory, as a non-pathologizing treatment meant to effect lasting change by addressing the immediate causes of individual dysfunction—the family and surrounding systems. The colorful and dedicated early pioneers in the field and their specific contributions to the field are reviewed. Dr. Mones weaves in his own personal experiences working with these individuals and what he has taken as valuable therapeutic knowledge to form his own integrated practice. Dr. Mones describes his career-long quest to find the essence of healing—what are the essential elements that makes psychotherapy effective and brings relief to individuals suffering a wide range of disorder from trauma and dysfunctional systems. Readers will benefit from Dr. Mones’ decades-long experience as a supervisor and teacher through his writing and learn how, they too, can find the meaningful parts of therapy that work to inform their own practice to create lasting change in their clients.
