a strategy that directs a researcher in planning and implementing a study in a way that is most likely to achieve the intended goal.
case study design an investigation strategy involving extensive exploration of a single unit of study, which may be a person, family, group, community, or institution, or a very small number of subjects who are examined intensively. The number of variables is usually very large.
cohort design longitudinal design.
cross-sectional design a research strategy in which one or more group(s) of subjects are studied at one given point in time.
experimental design a research design that eliminates all factors that influence outcome except for the cause being studied (independent variable). All other factors are controlled by randomization, investigator-controlled manipulation of the independent variable, and control of the study situation by the investigator, including the use of control groups.
longitudinal design a research strategy in which one or more group(s) of subjects in various stages of development are examined simultaneously with the intent of inferring trends over time. The assumption is that the phenomenon under study progresses with time. Called also cohort design.
methodological design a process used to develop the validity and reliability of instruments to measure constructs used as variables in research.
nonequivalent control group design a study design in which the control group is not selected by random means.
partial correlation design a design developed to eliminate the influence of a third variable on a relational pattern by holding it constant mathematically, so that the magnitude of the relationship between the two remaining variables can be determined.
path analysis design a design to determine the accuracy of a theoretical model: a hypothesized causal model is developed from the theoretical model and the major variables within it are measured and relationships among them determined; regression analysis is used to determine whether the data are consistent with the model.
survey design a design in which data are collected with questionnaires or through personal interviews with members of an identified population.
time dimensional design an investigation strategy for the examination of sequence and patterns of change, growth, or trends across time; see also prospective study and retrospective study.
trend design a research strategy to examine changes in the general population in relation to a particular phenomenon by means of data collected at predetermined intervals of time from different samples selected from the general population.

Q. Alcohol designator Order? What is an Alcohol designator Order?

A. Hello friend, Council can apply for an order to restrict public drinking in a particular area or areas. An order sets out the public areas affected e.g. streets, parks and open spaces, where the police could ask people to stop drinking alcohol if their behavior is deemed to be anti social. The police will be able to confiscate and dispose the alcohol and people could face a fine of up to £500 or arrest for refusing to cooperate.

Q. How to design and run a Ambulance Service effectively. Different Models, Costs, Safety features, Planning, Strategy, Promotions, Partnerships, Risks etc...

A. Hmm... this website ( ) contains a lot of information about how to run an ambulance service, from addresses to fee tables.

Hope I could help!
