Behind the hallowed walls of higher education are students who did not grow up expecting to attend college, students who walked through open doors not knowing what to expect on the other side. For some, these open doors became revolving doors, and they simply gave up. For many others, however, there were unexpected successes, successes that included more than academic accomplishments. These people came through the system with an increased sense of self-confidence that empowered them in the world beyond college. This oral history tells the story of the struggles as well as of the triumphs related to the fight for access and high quality in higher education. Thus, it provides a unique look at the past state of higher education, and at the measures that might be taken to improve our future educational system. The book begins with a brief historical overview of what access to higher education looked like before the 20th century. Following chapters tell the actual stories and are organized around four themes: the power of belief in students; access with success; institutional commitment; and effective support systems. Finally, a set of recommendations is provided that will help to keep the doors open for those still wishing to enter. Educators at all levels, graduate students studying higher education, and interested readers in the general public will all find this book an invaluable resource.

The Heinz Nixdorf Museum Forum (HNF) is the world's largest c- puter museum and is dedicated to portraying the past, present and future of information technology. In the "Year of Informatics 2006" the HNF was particularly keen to examine the history of this still quite young discipline. The short-lived nature of information technologies means that individuals, inventions, devices, institutes and companies"age" more rapidly than in many other specialties. And in the nature of things the group of computer pioneers from the early days is growing smaller all the time. To supplement a planned new exhibit on "Software and Inform- ics" at the HNF, the idea arose of recording the history of informatics in an accompanying publication. Mysearchforsuitablesourcesandauthorsveryquickly cameupwith the right answer, the very rst name in Germany: Friedrich L. Bauer, Professor Emeritus of Mathematics at the TU in Munich, one of the - thers of informatics in Germany and for decades the indefatigable author of the"Historical Notes" column of the journal Informatik Spektrum. Friedrich L. Bauer was already the author of two works on the history of informatics, published in different decades and in different books. Both of them are notable for their knowledgeable, extremely comp- hensive and yet compact style. My obvious course was to motivate this author to amalgamate, supplement and illustrate his previous work.

For some years, specification of software and hardware systems has been influenced not only by algebraic methods but also by new developments in logic. These new developments in logic are partly based on the use of algorithmic techniques in deduction and proving methods, but are alsodue to new theoretical advances, to a great extent stimulated by computer science, which have led to new types of logic and new logical calculi. The new techniques, methods and tools from logic, combined with algebra-based ones, offer very powerful and useful tools for the computer scientist, which may soon become practical for commercial use, where, in particular, more powerful specification tools are needed for concurrent and distributed systems. This volume contains papers based on lectures by leading researchers which were originally given at an international summer school held in Marktoberdorf in 1991. The papers aim to give a foundation for combining logic and algebra for the purposes of specification under the aspects of automated deduction, proving techniques, concurrency and logic, abstract data types and operational semantics, and constructive methods.

In today's unsafe and increasingly wired world cryptology plays a vital role in protecting communication channels, databases, and software from unwanted intruders. This revised and extended third edition of the classic reference work on cryptology now contains many new technical and biographical details. The first part treats secret codes and their uses - cryptography. The second part deals with the process of covertly decrypting a secret code - cryptanalysis, where particular advice on assessing methods is given. The book presupposes only elementary mathematical knowledge. Spiced with a wealth of exciting, amusing, and sometimes personal stories from the history of cryptology, it will also interest general readers.

This is a topical resource that provides a comprehensive look at the most influential women in Hollywood cinema across a wide-range of occupations rarely found together in a single volume. Unlike other anthologies, Hollywood Heroines: The Most Influential Women in Film History is a hybrid of film history and industry information with an exclusive focus on prominent women. This reference work includes more commonly discussed categories of important women in Hollywood film history, such as directors and actresses, and reaches beyond them to encompass women working as cinematographers, casting directors, studio heads, musical composers, and visual and special effects supervisors. The wide range of filmmaking crafts covered in the book provides an acute view of the industry and increases the visibility of and quality of representation for women working in Hollywood. By bringing the experience of these influential women to light, Hollywood Heroines joins a growing movement that endeavors to dismantle harmful, long-standing industry myths that perpetuate the systemic underrepresentation of women and the devaluation of women's stories in the Hollywood film industry.

The development of the internationally standardized language ALGOL has made it possible to prepare procedures which can be used without modification whenever a computer with an ALGOL translator is available. Volume Ia in this series gave details of the restricted version of ALGOL which is to be employed throughout the Handbook, and volume Ib described its implementation on a computer. Each of the subsequent volumes will be devoted to a presentation of the basic algorithms in some specific areas of numerical analysis. This is the first such volume and it was feIt that the topic Linear Algebra was a natural choice, since the relevant algorithms are perhaps the most widely used in numerical analysis and have the advantage of forming a weil defined dass. The algorithms described here fall into two main categories, associated with the solution of linear systems and the algebraic eigenvalue problem respectively and each set is preceded by an introductory chapter giving a comparative assessment.

Problem oriented programming languages as they have developed over the last ten years essentially serve two purposes which somewhat crudely can be described by the terms man-man communication and man-machine communication, respectively. As a carrier of information between humans, the problem oriented programming language is designed to express the essence of an algorithm in a way which is un ambiguous and concise as well as independent of (and therefore meaning ful without any reference to) the changing details of computing machine ry. As a carrier of information from man to computer, the language permits the human programmer to express his computational needs in a compact way adapted to the general characteristics of computers, but freed from the burdening details of specific computer facilities. This presupposes the existence of algorithms, or programs, which permit the computer itself to transform efficiently programs written in the problem oriented language into machine programs. Thus the entire computing community profits from the work of the individual programmer. The primary purpose of the Handbook is to present a set of algorithms of broad utility from the domain of numerical mathematics written in the problem oriented language ALGOL 60. Therefore, volumes I a and I b are in a sense supplementary as they serve to introduce this language. Volume I a gives a description of the language proper and of its use for writing correct programs. Thus, volume I a primarily covers the aspect of man-man communication by means of ALGOL 60.

Automatic computing has undergone drastic changes since the pioneering days of the early Fifties, one of the most obvious being that today the majority of computer programs are no longer written in machine code but in some programming language like FORTRAN or ALGOL. However, as desirable as the time-saving achieved in this way may be, still a high proportion of the preparatory work must be attributed to activities such as error estimates, stability investigations and the like, and for these no programming aid whatsoever can be of help. In this respect, ALGOL, as an internationally standardized notation which avoids computer-oriented concepts, provides another advantage, not often mentioned, but one which was already the guiding principle at the very beginning of the programming language venture: indeed, a correct ALGOL program is the abstractum of a computing process for which the necessary analyses have already been performed. It is the very purpose of this Handbook to establish such abstract formulations of certain computing processes. Therefore, numerical methods given in this Hand book in the form of ALGOL procedures may be put to immediate use wherever ALGOL is known and understood; in fact, application of such a method reduces to little more than calling the corresponding procedure."

Endoscopic neurosurgical interventions gain in importance. This book gives adetailed description of the recent indi- cations of endoscopic procedures inmodern neurosurgery. They include endoscopic stereotaxy, endoscopic evacuations of intracerebral hematomas, cysts and abscesses as well as endoscopic interventions on brain tumors. An extended over- view about the usable endoscopes and the operative equipment is pointed out

The Marktoberdorf Summer Schools on Informatics were started in 1970, with the intention to convene every second or third year a group of top researchers in computing, devoted to preach their most recent results to an elite of advanced students - young and most promising people - and prepared to stand their questions, criticism and suggestions. The themes of these Advanced Study In stitutes under the sponsorship of the NATO Scientific Affairs Division varied slightly over the years, oscillating more or less around Programming Methodo logy, as the following list shows: 1970 Data Structures and Computer Systems 1971 Program Structures and Fundamental Concepts of Programming 1973 Structured Programming and Programmed Structures 1975 Language Hierarchies and Interfaces 1978 Program Construction 1981 Theoretical Foundations of Programming Methodology 1984 Control Flow and Data Flow: Concepts of Distributed Programming 1986 Logic of Programming and Calculi of Discrete Design 1988 Constructive Methods in Computing Science 1989 Logic, Algebra, and Computation Logic, Algebra, and Computation is the theme of the summer school to which this volume is devoted. It is the tenth in succession, but it is also the first in a new series (the "blue" series) that is intended to alternate in future with the traditional (the "red" series) arrangement; in fact the tenth summer school in the "red" series with the title "Programming and Mathematical Method" , held in 1990, was the subject of celebrating both its serial number and the twenty years of Marktoberdorf Summer Schools altogether.

In 1992 the Editors published the first volume of Minimally Invasive Neurosurgery (MIN I) which described the current state of the art in this rapidly developing field of neurosurgery and reported first clinical experiences with these new technologies. The subject of MIN II is limited to endoscopic anatomy, technical devices and surgical management of disorders suitable for endoscopic procedures. The indications and approaches in different diseases are still highly preliminary and longterm results are not yet available. The clinical value and the benefit to the patients treated with these new techniques must still be proven against the well established standards of microsurgery. This volume presents a critical update of neuroendoscopy.

Severe head injuries are a frequent occurrence in the life of every emergency care specialist, traumatologist, neurosurgeon, and rehabilitation specialist. For example, between 30.000 to 40.000 severe head injuries occur in Germany each year. Over 75.000 Americans die each year after having suffered a severe head injury. Nevertheless, treatment is not always optimal. Survival and longterm outcome depends not only on the type of injury but also on timely and appropriate diagnosis and treatment. Thus, all physicians involved must be aware of the current procedures in the management of severe head injuries. This reference book, based on the experience of international experts, provides an up to date and practical guideline.

Der erste funktionsfahige Computer wurde von Konrad Zuse gebaut. Er war 1941 betriebsbereit. Der Erfinder dieser ersten vollautomatischen, programmgesteuerten, frei programmierbaren, in binarer Gleitpunktzahlrechnung arbeitenden Rechenanlage ware am 22. Juni 2010 hundert Jahre alt geworden. In diesem Buch erzahlt er die Geschichte seines Lebens, das wie kaum ein anderes mit der Geschichte der bedeutendsten technischen Entwicklung seines Jahrhunderts verbunden ist - einer Entwicklung, die mit der "Abneigung" des Bauingenieurstudenten Zuse gegen die statischen Rechnungen begonnen hat... "Von der ersten bis zur letzten Seite ist diese Autobiographie eine faszinierende Lekture, weil aus jeder Zeile das personliche Erleben des Autors spricht. Diese Unmittelbarkeit macht Buch und Autor sympathisch."

In today's extensively wired world, cryptology is vital for guarding communication channels, databases, and software from intruders. Increased processing and communications speed, rapidly broadening access and multiplying storage capacity tend to make systems less secure over time, and security becomes a race against the relentless creativity of the unscrupulous. The revised and extended third edition of this classic reference work on cryptology offers a wealth of new technical and biographical details. The book presupposes only elementary mathematical knowledge. Spiced with exciting, amusing, and sometimes personal accounts from the history of cryptology, it will interest general a broad readership.

Die Informatik selbst ist eine junge Wissenschaft, ihre Wurzeln aber reichen weit in die Vergangenheit zuruck. Der Autor zeigt dies auf unterhaltsame Weise und gleichzeitig mit mathematischer Strenge anhand zahlreicher Facetten aus der Geschichte der Informatik. Die Beitrage sind uber viele Jahre in der Zeitschrift Informatik Spektrum erschienen und erscheinen nun erstmals gesammelt als Buch."

"Advances in Neurosurgery 22" is devoted to three main topics, the first one being Cerebellar Infarcts. Following the introduction with the microsurgical anatomy and the neuropathology of cerebellar infarction, the indication for operative treatment and its results are then discussed. The neuroradiological treatment with local and antifibrinolytic therapy for vertebrobasilar occlusion completes this section. The management and surgical approaches to the various forms of midline lesions are then presented. Special interest is centred on minimal invasive endoscopic neurosurgery (MIEN), (intraventricular tumors, optic pathway gliomas, endoscopic brainstem tumors and vascular malformations). Furthermore the special equipment and fields of indications are extensively discussed.

"I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students. . . . We must understand and circumvent this dangerous discouragement. No one can predict where the future leaders of science will come from."--Carl Sagan In 2012, the White House put out a call to increase the number of STEM graduates by one million. Since then, hundreds of thousands of science students have started down the path toward a STEM career. Yet, of these budding scientists, more than half of all college students planning to study science or medicine leave the field during their academic careers. What Every Science Student Should Know is the perfect personal mentor for any aspiring scientist. Like an experienced lab partner or frank advisor, the book points out the pitfalls while providing encouragement. Chapters cover the entire college experience, including choosing a major, mastering study skills, doing scientific research, finding a job, and, most important, how to foster and keep a love of science. This guide is a distillation of the authors' own experiences as recent science graduates, bolstered by years of research and interviews with successful scientists and other science students. The authorial team includes former editors-in-chief of the prestigious Dartmouth Undergraduate Journal of Science. All have weathered the ups and downs of undergrad life--and all are still pursuing STEM careers. Forthright and empowering, What Every Science Student Should Know is brimming with insider advice on how to excel as both a student and a scientist.

Die Kryptologie, eine jahrtausendealte "Geheimwissenschaft," gewinnt zusehends praktische Bedeutung in Verbindung mit dem Schutz von Kommunikationswegen, Datenbanken und Software. Neben ihrer Nutzung in rechnergestutzten offentlichen Nachrichtensystemen ("offentliche Schlussel") treten zusehends rechnerinterne Anwendungen, die sich auch auf Zugriffsberechtigungen und den Quellenschutz von Software erstrecken.
Der erste Teil des Buches handelt in elf Kapiteln von den Geheimschriften und ihrem Gebrauch - von der Kryptographie. Im zweiten Teil wird in elf weiteren Kapiteln das Vorgehen zum unbefugten Entziffern einer Geheimschrift - die Kryptanalyse - besprochen, wobei sich insbesondere Hinweise fur die Verfahrensbeurteilung ergeben.
Das Buch setzt nur elementare mathematische Kenntnisse voraus. Mit einer Fulle spannender, lustiger und bisweilen anzuglicher Geschichten aus der historischen Kryptologie gewurzt, ist es auch fur den Laien reizvoll zu lesen."

Dass Buch will dem dringenden Bedurfnis nach besserem Verstandnis und scharferer nosologischer Einordnung des Begriffes "traumatisch-hirnorganisches Psychosyndrom" Rechnung tragen. Es ist das Ergebnis eines Workshops, bei dem Pharmakologen, Internisten und Neurochirurgen das Thema von mehreren Seiten beleuchtet haben. Die Vortrage wurden mit dem Auditorium, auch anhand von Fallbeispielen, diskutiert. Das Ergebnis ist eine Bestandsaufnahme uber das derzeitige Verstandnis des Syndroms mit Empfehlungen zur Analgosedierung.
