In a local area network (LAN) or intranet, there are many pieces of hardare trying to gain access to the network transmission media at the same time (i.e., phone lines, coax, wireless, etc.). However, a network cable or wireless transmission frequency can physically only allow one node to use it at a given time. Therefore, there must be some way to regulate which node has control of the medium (a media access control, or MAC, protocol). Ethernet is a MAC protocol; it is one way to regulate physical access to network tranmission media.
Ethernet networking is used primarily by networks that are contained within a single physical location. If you need to design, install, and manage a network in such an envronment, i.e., home or small business office, then this book will give you an in-depth understanding of the technology involved in an Ethernet network.
One of the major goals of this book is to demystify the jargon of networks so that the reader gains a working familiarity with common networking terminology and acronyms.
In addition, this books explains not only how to choose and configure network hardware but also provides practical information about the types of network devices and software needed to make it all work. Tips and direction on how to manage an Ethernet network are also provided.
This book therefore goes beyond the hardware aspects of Ethernet to look at the entire network from bottom to top, along with enough technical detail to enable the reader to make intelligent choices about what types of transmission media are used and the way in which the various parts of the network are interconnected.
*Explains how the Ethernet works, with emphasis on current technologies and emerging trends in gigabit and fast Ethernet, WiFi, routers, and security issues
*Teaches how to design and select complementary components of Ethernet networks with a focus on home and small business applications
*Discuses the various types of cables, software, and hardware involved in constructing, connecting, operating and monitoring Ethernet networks

While women are succeeding in historically male professions, stereotypes of their lack of competence persist as obstacles to their advancement, with popular media urging women to improve their language skills if they hope to advance in traditionally male professions.

In "Women Speaking Up: Getting and Using Turns in Workplace Meetings," Cecilia E. Ford rejects popular notions of gender difference and even deficiency in women's language use. She uses careful analysis of interaction to counter negative myths, focusing on women's turns as exemplars skills required by men and women alike to contribute to workplace meetings. Based on videotaped meetings in a variety of settings the author offers new insights into vocal and non-vocal practices for getting and using turns in these common workplace events. The book introduces conversation analytic methods and presents new findings on turn taking, the use of questions to present challenges and open participation, and the interactional skills required to effectively raise issues that go counter to ideas of higher ranking co-workers. For any one who wants to understand meeting interaction, Women Speaking Up offers a wealth of well-grounded new perspectives, while celebrating women's demonstrated competence.

The twentieth century discovered the concept of sacred place largely through the work of Martin Heidegger and Mircea Eliade. Their writings on sacred place respond to the modern manipulation of nature and secularization of space, and so may seem distinctively postmodern, but their work has an important and unacknowledged precedent in the Neoplatonism of Late Antiquity and the early Middle Ages. "Sacred Place in Early Medieval Neoplatonism" traces the appearance and development of sacred place in the writings of Neoplatonists from the third to ninth centuries, and sets them in the context of present-day debates over place and the sacred.

The Clinical Manual for Treatment of Alcoholism and Addictions provides a concise overview of addiction treatment issues relevant to physicians, nurses, psychologists, social workers, alcohol and drug counselors, and rehabilitation therapists who are involved in the care of patients with substance use disorders.

The manual - Presents an overview of the genetics, biological markers, and pathophysiology of addiction.- Covers specific addictive substances in detail -- including epidemiology, presentation, and diagnosis.- Highlights underlying issues related to each substance and includes sections on polysubstance abuse and psychiatric comorbidity.- Touches on various evaluation and assessment tools- Reviews psychosocial and pharmacological treatment modalities.

Throughout the book, complex material is made accessible through the generous use of tables and charts, and key points summarize the important take-away points for each chapter In addition, the manual offers extensive coverage of many different aspects of addiction psychiatry: - Specific patient populations, such as children and adolescents, seniors, mentally and physically handicapped persons, the chronically ill, and the homeless- Various treatment settings, such as general hospitals, outpatient medical settings, and emergency departments- Behavioral addictions, such as pathological gambling, kleptomania, and compulsive buying- Violence, crime, and suicidal behavior

With their vast impact on our culture and society, substance use disorders may well become one of the main challenges for psychiatry in the twenty-first century. Effective approaches to substance use disorders require treatment combinations tailored specifically to each individual. The Clinical Manual for Treatment of Alcoholism and Addictions is an invaluable tool for informing clinicians about the wide array of treatment options available to help their patients who struggle with substance abuse problems.

This book contains the papers presented at the NATO Advanced Study Institute (ASI) on the Basics of Man-Machine Communication for the Design of Educational Systems, held August 16-26, 1993 in Eindhoven, The Netherlands. The ASI addressed the state of the art in the design of educational systems with respect to theories, enabling technologies and advanced applications and implementation issues. The topics discussed are grouped into four main subject areas: 1) Fundamentals of human perception and reasoning, 2) New media: enabling technologies, 3) Artificial Intelligence; software and design techniques, and 4) Advanced applications. This interdisciplinary approach, with a clear focus on the application domain of learning environments, provided the platform for interdisciplinary exchange and communication between the participants. The role of human perception and reasoning was presented in the context of design requirements. The construction of usable human-machine interfaces requires designers to be aware of the inherent competence of the human user. That is, a designer needs to understand the resources that the user brings to the interaction. This includes the general nature of human and world interactions; the nature of the human perceptual system; the natural learning processes by which the information given by the senses is transformed into knowledge of the world; the reasoning processes that allow humans to make inferences from that knowledge once acquired; and the ways in which acquired knowledge may be communicated to others through language.

Relational Database Design and Implementation: Clearly Explained, Fourth Edition, provides the conceptual and practical information necessary to develop a database design and management scheme that ensures data accuracy and user satisfaction while optimizing performance. Database systems underlie the large majority of business information systems. Most of those in use today are based on the relational data model, a way of representing data and data relationships using only two-dimensional tables. This book covers relational database theory as well as providing a solid introduction to SQL, the international standard for the relational database data manipulation language. The book begins by reviewing basic concepts of databases and database design, then turns to creating, populating, and retrieving data using SQL. Topics such as the relational data model, normalization, data entities, and Codd's Rules (and why they are important) are covered clearly and concisely. In addition, the book looks at the impact of big data on relational databases and the option of using NoSQL databases for that purpose.

Countering popular myths of women's deficiencies in communicating in traditionally male professions, the author uses women's talk to illustrate the interactional skills required to contribute effectively to workplace meetings, and presents new insights on the organization of talk in meetings while celebrating women's clear competence.

The search for the meaning of life has been a challenge throughout history. "Reflect and Rejoice" is an effort to review my life--its high points, its low points, and a lot of in-between points. This is a reflection on my life's journey. I have had, what I would call, a fantastic life. I have been blessed with many opportunities and adventures. I have been an ordained Presbyterian minister for over fifty years and served varied congregations. I served as the pastor of the Protestant Congregation in Kathmandu, Nepal, which is an international and interdenominational congregation. Prior to going to Nepal, I served small rural churches and large urban churches in the Midwest and in Florida. There was much to learn in every situation. In this book I "reflect" on my life. And I "rejoice" in the experiences that have helped give me insight into how to sort out the important things in life from the chaff. I hope you will enjoy sharing in my journey.
