The Availability Heuristic01:08

The Availability Heuristic

7.1K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Analysis of Population Pharmacokinetic Data01:12

Analysis of Population Pharmacokinetic Data

814
Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

How Data are Classified: Categorical Data

45.1K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

How Data are Classified: Numerical Data

38.4K
Data that are countable or measurable in specific units are called numerical or quantitative data. Quantitative data are always numbers. Quantitative data are the result of counting or measuring the attributes of a population. Amount of money, pulse rate, weight, number of people living in a town, and number of students who opt for statistics are examples of quantitative data.
Quantitative data may be either discrete or continuous. All quantitative data that take on only specific numerical...

Data Reporting and Recording01:24

Data Reporting and Recording

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Summary
This summary is machine-generated.

Researchers are sharing more data, but few deposit it in repositories as PLOS policy prefers. Most state data is in the paper or supplemental files, raising concerns about true data accessibility and reuse.

Area of Science:

  • Open Science and Research Reproducibility
  • Scholarly Publishing Policies
  • Data Management Practices

Background:

  • Publishers and funders, including PLOS, now mandate data sharing for research reproducibility and reuse.
  • This policy aims to increase the availability of data for secondary analysis.

Purpose of the Study:

  • To assess author compliance with PLOS data sharing policies.
  • To analyze the trends in Data Availability Statements (DAS) over time.

Main Methods:

  • Analysis of 47,593 Data Availability Statements from PLOS ONE articles.
  • Study period: March 2014 to May 2016, coinciding with policy implementation.

Main Results:

  • Author compliance with data sharing policies has increased.
  • A significant decrease in papers lacking a Data Availability Statement was observed.
  • Only approximately 20% of statements indicated data deposition in a repository, the preferred method.

Conclusions:

  • While compliance is rising, current data sharing practices may not fully meet policy requirements.
  • Further review of Data Availability Statements or stricter policies are needed to enhance data sharing and accessibility.
