  • The study of the formation and early evolution of stars has been an ever growing part of astrophysical research. Traditionally, often in the shadow of its big brothers (i.e., the study of stellar structure, stellar atmospheres and the structure of galaxies), it has become evident that early stellar evolution research contributes essentially to these classical fields. There are a few new items on the list of traditional astrophysical studies, some of which are more related to features known from the extreme late stages of stellar evolution.

  • DEVELOPMENTS The aim of this chapter is to discuss briefly possible developments of VSAT future technology. The introduction of this book emphasised the fact that VSAT networks are part of the historical evolution of earth station technology towards a reduction insize and cost. From the link analysis developed in Chapter 5, it has become clearthat this evolution was possible thanks to the availability of satellite transponders with high EIRP and G/r.

  • The evolution of technological advances in infrared sensor technology, image processing, “smart” algorithms, knowledge-based databases, and their overall system integration has resulted in new methods of research and use in medical infrared imaging. The development of infrared cameras with focal plane arrays not requiring cooling added a new dimension to this modality. New detector materials with improved thermal sensitivity are now available and production of high-density focal plane arrays (640×480) has been achieved.

  • Every aspect of a network-storage, file transfers, backup-depends on the filesystem for structure, functionality, and integrity. Surprisingly, UNIX-the operating system of choice for mission-critical networks-has historically had little documentation on its filesystem structures. Written by Steve Pate, a sen-ior member of the VERITAS Filesystems Group, this book sheds light on the inner workings of UNIX filesystems and gives you the know-how to fine-tune your UNIX filesystems for optimal performance.

  • Computer science has drawn from and contributed to many disciplines and practices since it emerged as a field in the middle of the 20th century. Those interactions, in turn, have contributed to the evolution of information technology: New forms of computing and communications, and new applications, continue to develop from the creative interaction of computer science and other fields.

  • The Directive culminated in the passage of the 1989 Companies Act. Specifically, we explore how the UK accountancy profession and the government were concerned to construct, articulate and negotiate particular meanings of what it is to be professional, self regulated, independent and commercial. The second episode concerns the impact on the accounting profession of the Financial Services Act. Initially, this regulation, developed to improve "investor protection" as well as to abolish restrictive practices, was understood to be unrelated to the work of accountants.

  • Popular American films penetrate nearly every aspect of contemporaryWestern life, and to an only somewhat lesser degreemost all cultures of the world. Historically, there are powerful sociological, cultural, economic, and even political reasons for this, but we would also argue thatHollywood-style filmhas evolved so that filmmakers havemore control over the attention of filmgoers (Smith 2006) and, in essence, the humanmind. One source of evidence concerns the changing pattern of shot lengths.

  • During the last decades we have been experiencing the historic evolution of Information and Communication Technology’s integration into our society to the point that many times people use it transparently. As we become able to do more and more with our advanced technologies, and as we hide them and their complexities completely from their users, we will have accomplished the envisioned “magic” desideratum that any advanced technology must fulfi ll in Arthur Clarke’s vision.

  • My goal in this book is to introduce the reader to the evidence, both historical and contemporary, for how the reciprocal interactions between people and nature have developed, the urgency for action now to prevent truly disastrous consequences, and to make suggestions as to how we might go about doing so. While the book does not follow the usual organization for an introduction to human ecology, cultural ecology, or ecological anthropology text, the book covers much of this material in what I hope is a more engaging organization....

Sociology developed, however ambiguously, as a critical intellectual response to the theories and achievements of the Enlightenment in the eighteenth century, the political dimension of which was centrally focused on the theory and practice of constitutional rule....

  • On the edge of a grand plain, almost in the centre of France, rises a rich and beautiful city, time-honored and famous, for it stood there before France had begun and while Rome still spread its wide wings over this whole region, and it has been the scene of some of the most notable events in French history. The Gauls, one of whose cities it was, named it Genabum. The Romans renamed it Aurelian, probably from their Emperor Aurelian. Time and the evolution of the French language wore this name down to Orleans, by which the city has for many centuries been known. The broad Loire,...
