Milgram's Obedience to Authority
0 Views •
2020
Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.” Milgram’s Experiments Milgram (1963) wanted to test the validity of this defense, so he designed an experiment and initially recruited 40 men for his...

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN Many animal experiments rely on final data collection time points that are gathered from the harvesting and testing of organs and tissues. The use of appropriate methods for the collection of organs and tissues can impact the quality of the samples and the analysis of the data that is gleaned for the testing of the tissues. The method of euthanasia of the animal can also impact the quality of...

The health of wild fishes can be used as an indicator of aquatic ecosystem health. Necropsy-based fish health assessments provide documentation of visible lesions or abnormalities, data used to calculate condition indices as well as the opportunity to collect tissues for microscopic evaluation, gene expression and other more in-depth analyses.
FAQs
Authorized Center Necropsy supports environmental investigation by linking observed external and internal findings with targeted laboratory testing. These examinations can reveal evidence consistent with injury, disease, contamination, or nutritional problems, while histopathology, toxicology, and microbiology provide additional evidence. This layered approach helps distinguish possible causes and strengthens interpretation of unusual wildlife deaths.
Each laboratory approach contributes different evidence. Histopathology examines collected tissues for changes associated with disease or injury, toxicology investigates possible contaminants, and microbiology helps identify pathogens. These analyses complement the postmortem examination rather than replace it, allowing investigators to connect physical findings with environmental health concerns and evaluate several possible explanations for mortality.
Biosafety procedures help protect personnel and maintain controlled handling of potentially hazardous animal material. Chain-of-custody procedures document how tissues and other samples are collected, managed, and transferred. Together, these safeguards support reliable laboratory interpretation and help ensure that findings remain scientifically credible and legally defensible when they inform wildlife management, public health, or conservation actions.
At an approved facility, trained personnel conduct external and internal examinations before collecting tissues and other samples for possible laboratory analysis. Biosafety procedures guide handling, while chain-of-custody records document sample control and transfer. Depending on the findings, histopathology, toxicology, or microbiology may then be used to investigate disease, injury, contaminants, or nutritional problems.
This approach is especially relevant during unusual mortality events or when wildlife deaths may signal ecosystem stress. Findings can help investigate suspected pollution, emerging pathogens, nutritional problems, or physical injury. Because the examination combines direct postmortem observations with laboratory evidence, it can contribute to environmental monitoring and provide information needed for wildlife management responses.
Results can reveal conditions affecting wildlife and environmental health, including disease, contaminants, injury, or nutritional problems. Investigators may use this evidence to detect pollution, recognize emerging pathogens, evaluate ecosystem stress, and guide wildlife management. The documented findings can also support public health decisions and legally defensible conservation actions when environmental risks require a response.
