the systematic, rigorous investigation of a situation or problem in order to generate new knowledge or validate existing knowledge. Research in health care takes place in a variety of areas and has many potential benefits; the areas include professional practice, environmental issues affecting health, vitality, treatments, theory development, health care economics, and many others. Health care research can be conducted by one group of professionals for generation of knowledge specific to that group, or by a diverse group of researchers collaborating on a given health care problem.
applied research scientific investigations conducted to answer specific clinical questions or solve practice-related problems.
basic research scientific investigation that involves the generation of new knowledge or development of new theories; its results often cannot be applied directly to specific clinical situations.
correlational research the systematic investigation of relationships among two or more variables, without necessarily determining cause and effect.
descriptive research research that provides an accurate portrayal of characteristics of a particular individual, situation, or group. These studies are a means of discovering new meaning, describing what exists, determining the frequency with which something occurs, and categorizing information.
ethnographic research the investigation of a culture through an in-depth study of the members of the culture; it involves the systematic collection, description, and analysis of data for development of theories of cultural behavior.
experimental research objective, systematic, controlled investigation for the purpose of predicting and controlling phenomena and examining probability and causality among selected variables.
exploratory research studies that are merely formative, for the purpose of gaining new insights, discovering new ideas, and increasing knowledge of phenomena.
grounded theory research a research approach designed to discover what problems exist in a given social environment and how the persons involved handle them; it involves formulation, testing, and reformulation of propositions until a theory is developed.
historical research research involving analysis of events that occurred in the remote or recent past.
phenomenological research an inductive, descriptive research approach developed from phenomenological philosophy; its aim is to describe an experience as it is actually lived by the person.
qualitative research research dealing with phenomena that are difficult or impossible to quantify mathematically, such as beliefs, meanings, attributes, and symbols; it may involve content analysis.
quantitative research research involving formal, objective information about the world, with mathematical quantification; it can be used to describe test relationships and to examine cause and effect relationships.
Data-gathering techniques that are focussed on the significance of observations made in a study rather than the raw numbers themselves

In this article, we show how qualitative models can be used to address some of these problems and, thus, become a valuable complement for mathematical approaches to ecological modeling.
Qualitative models are a proper abstraction of real-valued models in the sense that they represent a class of real-valued models.
To this point, we have discussed the learning of qualitative models represented as qualitative trees.
The last session of the symposium dealt with qualitative models and was kicked off by a stimulating presentation by E.
To be able to use qualitative simulation for time management, two folded models are required: quantitative model (Ordinary Differential Equations (ODE)) and qualitative model (QDEs).
For example, in reasoning about a strategy game such as Freeciv, (4) the learned qualitative model of domain dynamics enables identifying trade-offs, and high-level strategies such as first expanding one's empire, then building up its economy, can be expressed by processes that are carried forward by a player's actions.
3 the solutions of qualitative models become interpretable after including about 25 pair-wise interrelations between variables.
Fuzzy Cognitive Maps (FCMs) are qualitative models of a system, consisting of variables (or concepts) and the causal relationships between those variables.
(4) The static structure of the simulation can be organized based on qualitative models and at run-time, qualitative models can intelligently choose the better execution branch or data based on the schedule engine.
The language of evidence-based practice mirrors the language of logical positivism, the paradigm on which it is predicated, in which knowledge is evaluated as being more or less "reliable" or "valid." However, many authors have argued that for social work practice, more heuristic, qualitative models may be more applicable to the actual nature of social work practice (Butler, Ford, & Tregaskis, 2007; Heineman, 1981).
Both good and bad samples allow us to set-up qualitative models with the FOX E-Nose.
The authors draw a distinction between quantitative and qualitative models, and they link abuses to the quantitative ones.
