of bridging the gap between theory and practice, a task that never seemed to . This knowledge ideally is connected to a scientific under- standing of the. The relationship between practice and theory is reciprocal. The larger theories are used to guide the practice of Information Science and they include the. of the natural sciences model for studying human The subject of the relationship between theory and . sciences, practitioners are expected to use theory in.
The different inferences are induced to generate the theory. Now the question arises: The answer is both yes and no. The research would be useless if the researcher has not fully explored the theoretical rationale and support from the related disciplines. Not to do so is negligence on the part of the research scientist.
It could be valuable if the no relevance theory is available, in which case non-theoretical research can form a basis for theory generation at later stages. God gives no linen, but flax to spin-German proverb Theory by providing a scientifically acceptable set of principles to explain a phenomenon3 performs numerous general functions proceeding from the scientific researcher to the research consumer.
Theory facilitates the inter-relatedness of isolated facts and observation in an organized and systematic manner. So an efficient mechanism is developed for accumulation of coherent research findings.

Consequently knowledge becomes more accessible to both the practitioner and the researcher. The condensation of knowledge by theory is crucial for the advancement of the knowledge base. Theory provides guidance by identifying a chain of events in a phenomenon.
Eventually a frilly developed theory takes one leap forward to explain why and how the phenomenon has occurred. The ideal state of theory development would be that it achieves the ability of bringing profitable change in the environment.
Theory motivates us to think and act for the continuation of knowledge by giving vision, direction and impulse to research. Research is like travelling to a new destination. There are chances that you can reach there without a map, but that would relatively be not a logical way to reach the destination. Theory generates the idea in us to enquire that what would be its application in situations known to us.
The researcher can only decide through definition whether different writers have the same meaning for a term or not. The language of theory has a specific scientific terminology. Here we are discussing the widely acceptable definitions and explanation of the terms. This is the smallest irreducible unit of research findings. This is the tile given to an abstract idea, event or object. These are based on real world experiences and represent generalized mental picture of characteristics of that phenomenon e.
However its description could be variable from research to research and theory to theory. According to the World Health Organization, health is a state of complete physical, mental and social well being and not merely the absence of disease or affirmity4 But the concept of health has other dimensions also esthetical, anatomical, physiological etc. For theorists, the process of conceptualization requires exposure to a vast amount of knowledge and experience.
In a theory, observable concepts, either directly or indirectly, are called constructs: Height, weight, socio-economic status While non-observable concepts are called theoretical constructs: Psychoanalytical theory assumes that behaviour springs from unconscious drives and conflicts.
Sigmund Freud coined the concepts of id, ego, and superego to explain his view of mind dynamics and personality under this theory6. This is a decorative statement regarding the nature of relationship s among the concepts. It provides a reason for the existence of a concept in a theory. It could be non-relational or relational. These are chronically malnourished children. These are cognitively deficit children.

Chronic mal-nourishment leads to cognitive deficit in the children. Facts and law are the only certain endpoints in the spectrum of knowledge. Conceptual framework or model: This refers to the pattern of organ isation of concepts, for explaining a phenomenon of interest during a pre-theory stage. They are prepared through the induction process.
These concepts are often abstract and multi-dimensional. As related systematic research is usually not available, and concepts are mainly evaluated logically, based upon non-systemic research findings and intuition. These frameworks are used for theory generation Theoretical framework or model: This refers to related to problem statement of interest.
It is prepared mainly through the deduction processes. They are used for postulating hypotheses for empirical testing. According to the psychoanalytic theory7. Now the problem statement is why secretaries, who are usually courteous and polite, are harsh and short tempered husbands. When the questions were empirically tested, it was found that in the office secretaries repress their desire to yell at the boss.
Which is congruent to the psychoanalytical theory that basic instincts of aggression are not fulfilled at officebelong to a substitute object wife is used for gratification out let for aggression Medical professionals often think that theories are social sciences and have no significant place in the biological sciences. This is a wrong assumption. Most of the major achievements in medicine are in fact theory based.
There was greater advancement in understanding the mechanism and treatment of physical pain, when empirical data was collected on the basis of pain gate theory by Malzack and Wall8. A theory is never proven or tested, it is the hypothesis deduced from it. Research and theory are only meaningful when work is simultaneously done upon them. This is the model that natural science employs in, for example, laboratory experiments. Stage 1 - Phenomena are observed.
Stage 2 - A testable hypothesis an educated guess is constructed to explain the phenomena.

Stage 3 - Empirical data factual information is collected in a systematic way. Stage 4 - The data is interpreted and analysed to see whether it confirms or refutes the hypothesis. Stage 5 - If the hypothesis is confirmed time and time again, it becomes a theory. If the data refutes the hypothesis, the scientist should reject or revise it, and begin the data-collection process again. The major scientific method in the natural sciences used for collecting data is the laboratory experiment.
Positivists also advocate the use of some types of secondary data, particularly official statistics. They argue that human behaviour is not the result of external social laws. Society is the product of interaction — meaning when people come together in social groups. The way people interpret these social interactions is centrally important to the understanding of social behaviour.What’s the difference between a scientific law and theory? - Matt Anticole
Interpretivists prefer methods such as unstructured interviews and observation because these uncover the meanings behind action and emphasise validity. Such methods attempt to see the social world through the eyes of the people who inhabit it by studying their everyday life verstehen or by letting those being studied speak for themselves.

Practical constraints on choice of method In addition to the theoretical, there are also practical reasons why a particular research method might be chosen. Funding — if the sociologist does not have access to large funds, a cheap method will be required. Secondary data is cheap because it has already been collected.
Postal questionnaires are cheaper than interviews, which are probably cheaper than observation studies.
