Current practices -- pt. 2. Toward a solution.This title reexamines and reconsiders the model of empirical research underlying most empirical work. The goal is neither a whitewash nor capital punishment, but rather it is to reform and mold empirical research into an activity that contributes as much as possible to a rigorous understanding of society. Without worrying about defining science or even determining the essence of the scientific enterprise, the goal is one that pools together logical thinking and empirically determined information. One of the fundamental issues to be addressed in this volume: Are there questions currently studied that are basically unanswerable even if the investigator had ideal nonexperimental data? If so, what are the alternative questions that can be dealt with successfully by empirical social research, and how should they be approached? In the chapters ahead, it will be important to keep in mind this doctrine of the undoable. Of course, one cannot simply mutter ";undoable"; when a difficult obstacle is encountered, turn off the computer, and look in the want ads for a new job-or at least a new task. Instead, it means considering if there is some inherent logical reason or sociological force that makes certain empirical questions unanswerable. There are four types of undoable questions to consider: those that are inherently impossible; those that are premature; those that are overly complicated; and those that empirical and theoretical knowledge have nullified.SociologyResearchMethodologySocial sciencesResearchMethodologyElectronic books.SociologyResearchMethodology.Social sciencesResearchMethodology.301/.072Lieberson Stanley1933-1046187MiAaPQMiAaPQMiAaPQBOOK9910455522603321Making it count2472932UNINA01457oam 2200445Ia 450 991069700680332120230902161726.0(CKB)5470000002384838(OCoLC)74282648(EXLCZ)99547000000238483820080513d2005 ua 0engurmn|||||||||txtrdacontentcrdamediacrrdacarrierOrdered and highly scalable granular media for shock mitigation[electronic resource] /by Robert Doney and Surajit SenAberdeen Proving Ground, MD :Army Research Laboratory,[2005]1 online resource (vi, 60 pages) illustrationsARL-TR ;3612Title from PDF title screen (Army, viewed July 22, 2010)."September 2005."Includes bibliographical references.ARL-TR (Aberdeen Proving Ground, Md.) ;3612.ShockBallisticsWave propagationnasatShock.Ballistics.Wave propagation.Doney Robert1423337Sen Surajit1423338U.S. Army Research Laboratory.DTICEDTICEGPOBOOK9910697006803321Ordered and highly scalable granular media for shock mitigation3550721UNINA
