Beskrivelse
Research should be enjoyable - whether it is a college student completing a project for a degree or a professor meeting requirements or expectations associated with his or her position. Learning the basics for conducting research is the first step. This text is a reader-friendly primer which has as its strength the facility to positively and gently ease the reader into the task of conducting research. Each chapter begins with a vignette, describing a hypothetical situation in which students might find themselves. By chapter's end, students should be equipped with the knowledge on how to address the confusion or problem presented in the appropriate scenario. Another pedagogical tool is the Methodological Link which refers to excerpts from actual criminal justice and criminological research, the full text which is available in a companion text Readings for Research Methods in Criminology and Criminal Justice. Each chapter also ends with Methodological Queries, questions and exercises requiring students to apply what has been learned.One prerequisite for the evolution of multicellular organisms was the invention of mechanisms by which cells could adhere to one another. At some point in our history, dividing cells no longer went their separate protozoic ways in the primordial oceans, but instead found that by maintaining an association, by sticking together but not fusing, numerous evolutionary advantages became possible. The subsequent development of specialized tissues and organs depended on the elaboration of incredibly sophisticated, regulatable cell-to-cell adhesion mechanisms which are known to operate in biological processes as diverse as the growth of the embryo, the immune response, the establishment of connections between nerve cells, and arteriosclerosis, to name just a few. Although we can only guess at the ancestral mechanisms that fostered the first primitive intercellular unions, some one billion years ago, we now recognize contemporary molecular "themes" with presumably ancient origins that mediate cell-cell interactions. The chapters in this book serve as useful, thought-provoking, but not exhaustive, commentaries on contemporary topics within the broad field of cell adhesion. If the reader detects a slight tilt toward those adhesion molecules that function in the nervous system, this is merely a reflection of this editor's interests, biases, and of course, limitations.
