"Only 50 people answered my survey—is that normal?" Looking at a table of "typical" response rates is somewhat like reading a BMI table—it provides a frame of reference, butdoesn't actually make a difference. This is particularly true of surveys, where typical can cover substantial ground...
Survey response rates refer to the proportion of people invited to take part in a survey who actually go on to complete it. The response rate is not the same as an Incidence Rate (the proportion of a population who meet required targeting criteria and could participate) or the Strike Rate ...

However, two significant advances have recently been made using viable PNAs to repair segmental-loss PNIs: (1) hydrogel release of Treg cells that reduce the immunological response and (2) PEG-fusion of donor PNAs that reduce the immune response, reduce and/or suppress much WD, immediately ...
Weybright’s project tracked a decade of adolescent responses to a question about boredom in a nationwide survey. Adolescents were asked to rate their response to the question “I am often bored,” on a five-point scale. Weybright and her colleagues analyzed the results over time and across ...
Based on the survey data of typical irrigation farmers in Zhangye City,Gansu Province and Baotou City,Inner Mongolia Autonomous Region in 2007,using the single input factors technical efficiency determination theory,the surveyed farmers' irrigation water use efficiency was evaluated objectively by using ...
Survey of Common Waterhemp (Amaranthus rudis) Response to Protox- and ALS-Inhibiting Herbicides in Northeast Kansas A population of common waterhemp in northeast Kansas was confirmed resistant to protoporphyrinogen oxidase (protox)-inhibiting herbicides in 2001. In 2002,... JEANNE S. FALK, DOUGLAS ...
The convective gas temperature boundary conditions and their transient response behavior were obtained from the full engine thermal survey data. In order to obtain metal temperatures for the HP and LP turbine rotors, steel pins of a known hardness were embedded into the parts at locations of ...
Climate change response and air pollution control have high consistency and significant synergy in terms of goals and measures. The control of air pollution in the SCB is particularly critical to achieving China's peak carbon emissions and carbon neutrality goals. The air pollution of typical megacit...
In response to this challenge, quantifying the effects of climate change and human activities on runoff can better understand the hydrological circulation. Numerous studies have shown that the variation in runoff is the result of a combination of climate change and human activity (He et al., 2019...
