Experimental Protocol for Manipulating Plant-induced Soil Heterogeneity
Published on: March 13, 2014
Summary
US researchers experienced increased creativity following the 2009 stimulus package. However, funding decisions were complicated by the requirement for rapid research outcomes.
Area of Science:
- Science funding
- Research policy
- Innovation
Background:
- The 2009 American Recovery and Reinvestment Act (ARRA) aimed to stimulate the economy.
- Significant funding was allocated to scientific research.
- The stimulus package emphasized timely project completion.
Purpose of the Study:
- To assess the impact of the 2009 stimulus package on research applications.
- To examine the influence of rapid results requirements on research creativity and funding decisions.
Main Methods:
- Analysis of research grant applications submitted during the stimulus period.
- Review of funding allocation criteria and decision-making processes.
- Qualitative assessment of research output and innovation.
Main Results:
- The stimulus package fostered a surge in research proposals.
- The pressure for quick results presented challenges in funding allocation.
- Balancing speed with scientific rigor was a key consideration.
Conclusions:
- The 2009 stimulus package successfully boosted research activity.
- Funding mechanisms needed to adapt to the demand for rapid outcomes.
- Future stimulus initiatives should consider the implications for research timelines and creativity.

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 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 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.
What is an Experiment?
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...
Randomized Experiments
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Experimental Designs
An experimental design is a systematic process that allows researchers to evaluate the relationship between dependent and independent variables. There are three widely used types of experimental design - pre-experimental design, true experimental design, and quasi-experimental design. In pre-experimental design, the researcher compares the data before and after some interventions or treatments. The true-experimental design has more than one purposefully created group, a commonly measured...
