Preface to the Seventh Edition Since the first edition of this work in 1986, enormous changes have occurred in professional ethics in Arkansas: the ...

Questions are raised about the potential of embryo cloning, or blastomere separation, both to increase the rate of pregnancy following in vitro fertilization and to provide sufficient material for preimplantation genetic diagnosis. Nevertheless, it is concluded that research on blastomere separation in the human should continue.

Focused on the field of knowledge lying between digital and analog circuit theory, this new text will help engineers working with digital systems shorten their product development cycles and help fix their latest design problems. The scope of the material covered includes signal reflection, crosstalk, and noise problems which occur in high speed digital machines (above 10 megahertz). This volume will be of practical use to digital logic designers, staff and senior communications scientists, and all those interested in digital design.

Applied Christian Ethics addresses selected themes in Christian social ethics. Part one shows the roots of contributors in the realist school; part two focuses on different levels of the significance of economics for social justice; and part three deals with both existential experience and government policy in war and peace issues.

School violence is a burning issue these days. This book provides an in-depth analysis of violence prevention programs and an assessment of their effectiveness, using data from observations, individual interviews, and focus groups, as well as published data from the schools. It is distinguished by its focus on the cultural and structural context of school violence and violence prevention efforts. Where most other researchers use quantitative measures, such as surveys, to assess the effectiveness of violence prevention programs, the authors of (...) this book use qualitative research and ethnography to study the environment where such programs take place. Thus, this work--one of only a few ethnographic studies of violence prevention programs in schools--links previous quantitative research on the topic and critical ethnography. _Preventing Violence in Schools: A Challenge to American Democracy_: *includes voices of school students, accused of practicing violence, who have been participants in violence prevention programs; *analyzes a citywide peer mediation program ; *examines the kinds of violence recognized in schools and the ways schools themselves may perpetuate violence; and *describes a violence prevention program for students at an alternative school. _Preventing Violence in Schools: A Challenge to American Democracy_ is highly relevant for students in courses on urban education, foundations of education, education and social policy, youth and the law, and qualitative research, and for teachers, administrators, and other professionals, such as school psychologists and guidance counselors, at the middle and high school levels.

The present study applies a new method for investigating dynamic unconscious processes. The method consists of selection of words from patient interview and test protocols that in the clinicians' judgments capture the patients' conscious symptom experience and the hypothetical unconscious conflict related to the symptom, subliminal and supraliminal presentation of these words, signal analysis of event-related potentials obtained to the word presentations. Eight phobics and three patients suffering from pathological grief reactions served as subjects. A time-frequency ERP analysis revealed that (...) subjects' ERPs classified the unconscious conflict words better subliminally than supraliminally, while the reverse was true for the conscious symptom words = 2.82, p = .011). The relationship between frequency and latency revealed a similar mirror image pattern for the unconscious conflict and conscious symptom words . This method demonstrated that objective, brain-based evidence for unconscious conflict can be obtained. (shrink)

Several issues are raised concerning the notion that a single strategy explains Fitts' law and the linear speed/accuracy trade-off. Two additional concerns are discussed: (1) distance is programmed, (2) the fact that movements produced without the aid of vision obey Fitts' law does not mean that sighted movements must be explained without regard to vision.
