Capturing Representative Hand Use at Home Using Egocentric Video in Individuals with Upper Limb Impairment

2.9K
A protocol is proposed to capture natural hand function of individuals with hand impairments during their daily routines using an egocentric camera. The goal of the protocol is to ensure that the recordings are representative of an individual's typical hand use during activities of daily living at...

Effects of Different Connection Modes of Electroacupuncture on Electrocardiogram and Nerve Discharge in Rats

629
Until now, there is no uniform method for electroacupuncture connection in clinical and fundamental research. We present a protocol that attempted to compare the effects of different connection methods on electrocardiogram (ECG) and neural discharge in rats to explore the most appropriate way to connect the electroacupuncture instrument.

What is a Mode?

25.1K
The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set.
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...

Summary
This summary is machine-generated.

Online surveys for egocentric networks yield more names than in-person interviews. However, interviewer engagement in face-to-face surveys can significantly increase name-elicitation, matching online survey results.

Area of Science:

  • Social Sciences
  • Sociology
  • Network Analysis

Background:

  • Egocentric network surveys are susceptible to methods effects, impacting data quality.
  • Understanding these effects is crucial for accurate social network research.

Purpose of the Study:

  • To experimentally compare name-elicitation in in-person versus online survey modes.
  • To investigate the role of interviewer behavior in face-to-face network data collection.

Main Methods:

  • A true experiment randomly assigned over 850 general population respondents to either in-person or online surveys.
  • Audio recordings analyzed in-person interviews to assess interviewer effects.
  • Name-eliciting questions were administered across both survey modes.

Main Results:

  • Face-to-face interviews showed higher cooperation and data quality but fewer names elicited compared to web surveys.
  • Interviewer differences were key: active interviewers elicited as many names as web surveys.
  • Methods effects influenced the volume of alters listed but not variable associations.

Conclusions:

  • Interviewer engagement is critical for maximizing name-elicitation in face-to-face egocentric network studies.
  • While online surveys may yield more names, tailored interviewer training can bridge the gap.
  • Careful consideration of survey mode and interviewer practices is essential for robust network data.
