Human behavior determinants

One way in which archaeologists have attempted to circumvent the danger of possible misassociation of sample with cultural event is to obtain a 14C determination directly on the cultural item itself. In certain contexts, however, an even more fundamental question is whether the phenomena in question can be related to human behavior at all. This, for example, is one of the basic questions that continues to arise in discussions concerning the antiquity of Homo sapiens in the Western Hemisphere.

As described above, steroid hormones can affect many aspects of human behavior. However, correlations between specific steroid hormones and a given behavior often are weak. Many factors, including genetics, developmental experiences, cognitive states, and context variables determine human behavior, and may of course contribute to behavioral expression. 

Finally, the MOS should also take into account the uncertainties in the estimated exposure. For predicted exposure estimates, this requires an uncertainty analysis (Section 8.2.3) involving the determination of the uncertainty in the model output value, based on the collective uncertainty of the model input parameters. General sources of variability and uncertainty in exposure assessments are measurement errors, sampling errors, variability in natural systems and human behavior, limitations in model description, limitations in generic or indirect data, and professional judgment. 

Rational-CHOICE theory aims at explaining human behavior. To achieve this, it must, in any given case, proceed in two steps. The first step is to determine what a rational person would do in the circumstances. The second step is to ascertain whether this is what the person actually did. If the person did what the theory predicted he would do, it can add the case to its credit side. Similarly, the theory can fail at each of the two steps. First, it can fail to yield determinate predictions. Second, people can fail to conform to its predictions -they can behave irrationally. 

One aspect of this project is the analysis of the stone tools and manufacturing debris recovered from excavated sites. In addition to standard typological and attribute analysis, a program of identification and source determination for lithic materials using instrumental neutron activation analysis (INAA) and petrography was carried out. The purpose of this research program was to provide insights into questions about ancient human behavior Where, when, why, and how did prehistoric peoples use the natural resources in their environs (2) ... 

Human behavior is, of course, extremely diverse and complex, composed of numerous different functions, any or all of which might be perturbed by exposure to a toxicant. Thus, understanding how a chemical affects human behavior may require a determination of its effects across these different behavioral functions. Furthermore, some... 

Our basic terminology about genes and gene expression in place, we can now consider the three sets of variables that determine human behavior and intelligence ... 

Richard Leakey argued that human beings are not innately aggressive, but cooperative and that human behavior is determined chiefly by learning (Darwin and Norton, 1979). 

It is becoming clear that certain trace elements are very important in determining human behavior. For example, lithium (administered as lithium carbonate) has been a miracle drug for some people afflicted with bipolar disorder, a disease that produces oscillatory behavior between inappropriate "highs" and the blackest of depressions. Although its exact function remains unknown, lithium seems to moderate the levels of neurotransmitters (compounds that are essential to nerve function), thus relieving some of the extreme emotions in sufferers of bipolar disorder. 

We also need to look at the process models used in the decision making. What information did the decision makers have or did they need related to the inadequate control actions What other information could they have had that would have changed their behavior If the analysis determines that the person was truly incompetent (not usually the case), then the focus shifts to ask why an incompetent person was hired to do this job and why they were retained in their position. A useful method to assist in understanding human behavior is to show the process model of the human controller at each important event in which he or she participated, that is, what information they had about the controlled process when they made then-decisions. 

After completing the event timeline, the analyst must determine which human failure or success subevents are suitable for further analysis suitability is based on the quality of available information. The analysis consists of a detailed interpretation of the context of the performance and information on what influenced human behavior and how human behavior contributed to the scenario evolution. A large portion of this analysis is dedicated to determining which PSFs affected the performance. Analysts determine which PSFs contribute to the scenario by using PSF details. The analyst marks each PSF detail that affected the sub-event the parent PSF is automatically checked when the PSF detail is selected. Table 2 displays a set of PSF details for the Training PSF. 

Other issues that management cited as needing more attention included worker accountability and the importance of human behavior as a determinant of safety outcomes. One corporate safety official also said that the industry must get even better at training. However, the safety issues most frequently cited by management as needing attention in the future were fatigue and the need to attract new employees into the industry. One respondent explained ...
