Personal experience factors

In robustness tests, usually the factors are examined at two extreme levels.For mixture-related and quantitative factors, these levels usually are chosen symmetrically around the nominal. The range between the extreme levels is selected so that it represents the variability that can occur when transferring the method.However, specifications to estimate such variability are not given in the ICH guidelines. Often the levels are chosen based on personal experience, knowledge, or intuition. Some define the extreme levels as nominal level +x%. However, this relative variation in factor levels is not an appropriate approach, since the absolute variation then depends on the value of the nominal level. Another possibility is to define the levels based on the precision or the uncertainty, with which... 

It is not easy to get the necessary information to do a good cash flow analysis. Start with your checkbook, credit card statements, and tax records. The most difficult information to get will be what you spend on cash purchases. The best approach is to keep a journal for a couple of weeks to get a pattern and then estimate the amounts factoring in your personal experience. Income information should be available from your tax records. 

Attempts have been made to use stress-testing results to classify compounds as extremely labile, very labile, labile, and stable (71). The basis for this classification system was the personal experience of the authors. In this section we will attempt to outline and discuss some of the factors that need to be considered when attempting to interpret the results of stress testing, and to provide references to other resources. It is our opinion that insufficient information has been gathered to provide a definitive classification system. 

One interesting aspect of doing the history of 20th century chemistry is that the events are likely to be close to the personal experience of chemist-readers. Or they may see their Doktorvaters in them. Since we are human, and prone to selfjustification, that proximity in time is likely to lead the responder to focus on the critical - the fact missed, the factor misjudged. 

Like the range of colors seen in a prism, manic depression or bipolar disorder has a spectrum from which psychiatrists make their diagnosis. One of the factors they examine is whether the person is in a depressed, manic, or hypomanic state. A hypomanic state is one in which a person experiences a more controlled mania. The person may become excessively active and feel elated, but does not become disorganized or delusional. People with these symptoms may be cyclothymic, that is they exhibit periods of depression and mania, but for shorter and less intense durations. 

Together these three sets of factors influence what a person experiences when lie or she takes a drug. You may have guessed that the path to a drug experience is not always easy to chart. However, many people are trying to do just that—to understand how drugs affect people. The accumulated knowledge from these efforts is the foundation of this book. 

The first real attempt to quantitatively survey serum levels in disease was reported in 1960 by Heremans (H14). In 1965, McKelvey and Fahey (M9) followed up, and to date over 300 papers have appeared it is not feasible to name all the contributors. In this section we will consider the factors that affect results and the normal ranges and then select and substantiate those areas where clinical value emerges as judged from personal experience of some 50,000 measurements over 5 years. 

The analysis of a series of chiroptical spectra and recovery of systematic trends in a given set can be carried out in several ways. In the past, the results strongly depended on the spectroscopist s personal experience actually, this was the least objective part of the circular dichroism application. Nowadays, we can rely on general procedures of statistical data treatment like singular value decomposition, factor analysis (especially its first part, analysis of the correlation matrix and the projection of the experimental spectra onto the space of orthogonal components), cluster analysis and the use of neural networks. This field has been pioneered by Pancoska and Keiderling [72-76], and also by Johnson [77] when analyzing the chiroptical properties of biopolymers. 

Among these factors, seven refer to agronomic aspects (absence of residues, selectivity, action spectrum, persistence, speed of action, specific action on grass weeds or specific action on dicotyledons), the others relate to economic reasons, safety, and direct (personal experience) or indirect (retailer advice, company assistance) information. The economic aspect plays an important role, demonstrated not only by the high score of the specific item (costs) but also by the indirect economic fall-out of other...

In contrast to all other types of panels, consumers are not given any training, and therefore are only employed for preference and acceptance tests. Their answers are subjective and food acceptance is influenced by many factors like personal experience, sex, age, regular use of the product, eating habits, and social and nutritional aspects. 

Some work has been done to find literature data on the impact of electrode weight or contact pressure on film resistance values but little information has been found. From the observations above and the personal experiences of one of the authors it appears that contact pressure may be an important factor when currents are high enough to make the contacts hot. 

Regardless of the severity of an outcome, from death at one end of the scale to no detectable damage at the other, the causation factors which gave rise to the accident and created the hazard remain unchanged. It is the information on NDD accidents that we must collect, analyse and act on if hazards and injuries are to be avoided. This is based on the principle that not all accidents result in injury. We have known for years that there is a relationship between the total ntrmber of accidents a person experiences and the number that result in injury. It could be that continued expostrre to accidents evokes the laws of probability and eventually the luck runs out. This in no way suggests that accidents are a function of luck but rather that the accident outcome may contain a component of ill fortime. The only way to ensttre the prevention of injury is to prevent the accident. 

As discussed above many different factors influence the process of RFA, which make a vendor s recommendation regarding a specific ablation algorithm only a rough estimate (Goldberg 2001). Therefore, an individual learning curve is necessary to collect enough personal experience to understand and to control the process of ablation sufficiently and to warrant an efficient result in terms of tumour control (Poon et al. 2004b).
