The Scientific Method01:32

The Scientific Method

The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...
The Scientific Method02:40

The Scientific Method

Research is what makes the difference between facts and opinions. Facts are observable realities, and opinions are personal judgments, conclusions, or attitudes that may or may not be accurate. In the scientific community, facts can be established only using evidence collected through empirical research.
The Scientific Method03:50

The Scientific Method

Chemistry is an empirical science. Scientists often pose questions to understand the chemistry in everyday life and seek answers to these questions. To achieve this, scientists follow a definitive series of steps that together make up the Scientific Method. This approach involves making observations, asking questions, building a hypothesis, conducting experiments, analyzing results, and forming a conclusion.
Scientific Nature of Social Psychology01:30

Scientific Nature of Social Psychology

Social psychology is a scientific discipline dedicated to understanding how individuals think, feel, and behave in social contexts. Unlike common sense, which relies on anecdotal experiences and intuition, social psychology employs systematic research and empirical methods to ensure objectivity and reliability. This distinction is fundamental in distinguishing scientifically supported findings from mere speculation.Four fundamental scientific values guide a structured approach to research in...
Free Energy01:21

Free Energy

Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break down the...
Synthetic Biology02:55

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Area of Science:

  • Biomedical Research
  • Scientific Publishing
  • Information Access

Background:

  • Scientific publishing evolves with online access and open access journals.
  • Funders and universities increasingly mandate public accessibility of research.
  • Focus on HIV vaccine research accessibility, crucial for developing nations.

Purpose of the Study:

  • Investigate publication access at global institutions.
  • Analyze access to HIV vaccine research literature.
  • Assess the impact of open access and subscriptions on information retrieval.

Main Methods:

  • Selected 50 recent HIV vaccine papers and 200 cited articles.
  • Assessed subscription access levels at various institutions worldwide.
  • Evaluated access through the WHO HINARI program.
  • Examined response rates for reprint requests via email.

Main Results:

  • 80% of recent HIV vaccine papers required subscriptions; 67% of cited papers were freely available.
  • Institutional subscription access varied widely (20%-90%).
  • HINARI program provided comparable access for low-income countries.
  • Email reprint requests had a 55-60% success rate, with delays.

Conclusions:

  • Institutional subscriptions are vital but don't guarantee full access to HIV vaccine research.
  • Multiple methods supplement subscriptions, including direct author contact.
  • Disparities in access levels create an uneven playing field for researchers.
