Archival Research01:40

Archival Research

17.5K
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...

Data Collection by Observations

15.6K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

Censoring Survival Data

634
Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...

Data Collection II01:29

Data Collection II

10.4K
The nursing history captures and records the patient's health status, so that a care plan evolves to meet the patient's individual needs. The nursing health history is a part of the initial assessment. A comprehensive history covers all health dimensions and plays a significant role in the assessment process. A comprehensive history includes the patient's biographical information, reasons for seeking health care, expectations, present and past health history, medications, and...

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

1.8K
When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...

Methods of Documentation V: CBE

1.5K
Charting by Exception, or CBE, is a method of documentation used in healthcare, particularly in nursing, that focuses on documenting only significant or abnormal findings rather than recording every detail. This approach aims to streamline the documentation process, improve efficiency, and ensure that healthcare providers can quickly identify deviations from normalcy in patient assessments.
In CBE, healthcare professionals establish predefined standards of practice that define what constitutes...

Summary
This summary is machine-generated.

Improving metagenomics data discoverability requires richer contextual information. Enhancing records in the European Nucleotide Archive showed benefits but highlighted the need for sustainable, submitter-driven annotation alongside curation.

Area of Science:

  • Genomics
  • Bioinformatics
  • Data Science

Background:

  • Discoverability of sequence data in archives like the European Nucleotide Archive (ENA) depends on associated contextual information.
  • Metagenomics research generates vast amounts of sequence data, necessitating effective data management and accessibility.

Purpose of the Study:

  • To improve the contextual information for metagenomics sample records in the ENA.
  • To assess the benefits, costs, and sustainability of third-party annotation for public environmental data.

Main Methods:

  • Conducted an exercise to enhance sample record annotations in the ENA.
  • Outlined the specific annotation process undertaken.
  • Summarized the findings from this data enrichment effort.

Main Results:

  • The annotation exercise successfully increased the usability of publicly available environmental metagenomics data.
  • Third-party annotation is effective but resource-intensive, demonstrating value as part of a broader curation strategy.

Conclusions:

  • While third-party annotation offers benefits for data discoverability and usability, its high cost necessitates a balanced approach.
  • A sustainable strategy should integrate submitter-driven annotation with supplementary third-party curation efforts.
