Replication-extension studies
combine and compare results from one or more prior studies with results from a new study
. The new study is specifically designed to replicate and extend the results of the prior studies.
What is replication plus extension?
Replication-plus-extension.
A replication study in which researchers replicate their original study but add variables or conditions that test additional questions
.
What is an extension of research?
Extension services can
provide research institutions with information on research requirements and play
a mediatory role between farmers and researchers. Extension services require a continuous flow of information from research institutions on new and improved practices.
What is your replication?
DNA replication is
the process by which DNA makes a copy of itself during cell division
. … The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.
What is conceptual replication?
Conceptual replication means that
researchers re-test the same theoretical idea or hypothesis repeatedly
, but use different populations, different ways of manipulating variables, different ways of measuring variables, or using different study designs.
What is a replication study?
A replication study is a study that
is an independent repetition of an earlier, published study, using sufficiently similar methods (along the appropriate dimensions) and conducted under sufficiently similar circumstances
.
14
. Clearly, this definition requires some explanation.
Is replication part of scientific method?
Replication is one of
the key ways scientists build confidence in the scientific merit of results
. When the result from one study is found to be consistent by another study, it is more likely to represent a reliable claim to new knowledge.
What is the purpose of extension?
– Extension is an informal educational process directed toward the rural population. This process offers advice and information to help them solve their problems. Extension also aims to
increase the efficiency of the family farm
, increase production and generally increase the standard of living of the farm family.
What is the purpose of the extension service?
Extension provides
non-formal education and learning activities to people throughout the country
— to farmers and other residents of rural communities as well as to people living in urban areas.
What is the extension program?
An extension programme is
a written statement which contains the following four elements
: Objectives which the agent expects to be achieved in the area within a specified period of time. This will often be a one-year period, to enable the agent to review the programme at the start of each farming year.
What are the 4 steps of replication?
- Step 1: Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands.
- Step 2: Primer Binding. The leading strand is the simplest to replicate.
- Step 3: Elongation.
- Step 4: Termination.
What is replication in your own words?
The
act or process of replicating something
. b. Biology The process by which genetic material, a single-celled organism, or a virus reproduces or makes a copy of itself. c. In scientific research, the repetition of an experiment to confirm findings or to ensure accuracy.
What are the three major steps in DNA replication?
Replication occurs in three major steps:
the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment
.
What is an example of conceptual replication?
These are not objectively defined quantities, so we have to decide on something reasonable. For example, in the 1970s Alice Isen found that
people were far more likely to help someone who had dropped some papers after they had found a dime in a phone booth
(Isen & Levin, 1972).
What are the two types of replication?
There are two types of replication Blomquist1986:
literal and construct
.
What is the difference between direct replication and conceptual replication?
Exact replications tell us
whether the original findings are true
, at least under the exact conditions tested. Conceptual replications help confirm whether the theoretical idea behind the findings is true, and under what conditions these findings will occur.
