Ethics in Research01:56

Ethics in Research

24.1K
Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Archival Research01:40

Archival Research

16.5K
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

184
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Introduction to Epidemiology01:26

Introduction to Epidemiology

1.0K
Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...

What is an Experiment?01:12

What is an Experiment?

15.1K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Bias01:22

Bias

5.5K
Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

Area of Science:

  • Public Policy
  • Science Communication
  • Political Science

Background:

  • Understanding how policymakers define research is crucial for scientists communicating with policy audiences.
  • Few studies have explored how policymakers, specifically US state legislators, define research evidence.

Purpose of the Study:

  • To investigate how state legislators in the USA define research evidence.
  • To identify characteristics of research that align with or differ from scientific definitions among policymakers.

Main Methods:

  • Conducted in-depth interviews with 168 policymakers in two Midwestern states.
  • Included 32 legislators identified as exemplary research users.
  • Triangulated findings through interviews with key informants.

Main Results:

  • Many legislators defined research similarly to scientists, emphasizing peer-reviewed studies.
  • Some legislators used a broader definition, including anecdotes and prioritizing accessibility, relevance, credibility, and unbiased information.
  • Legislators distinguished credible research from 'bogus,' 'party,' or 'pseudoscience' research.

Conclusions:

  • Scientists can improve policy engagement by aligning communication with legislators' preferred evidence types and qualities.
  • Transparency regarding funding and study motivation enhances research credibility for policymakers.
  • Acknowledging legislators' broader definitions can foster better research-policy interactions.
