Each of these implies a somewhat different mode of operation in the detection situation buy prandin 0.5mg with amex. According to the conditioned response theory the critical questions play the role of conditioned stimuli and evoke some "emotional" response with which they have been associated in the past purchase prandin 2 mg fast delivery. It would therefore be expected that questions relating to some fairly traumatic experience would produce especially large reactions buy cheap prandin 0.5mg on-line. If this is the basis of detection, lies about trivial matters would be nearly impossible to detect. Asserting that a barn is a house, for example, would produce little response from the ordinary individual because neither word is connected with any large reaction on his past life. Denying that he took part in a crime might be -161- expected to produce a large reaction on this theory, because the crime probably produced a large "emotional" disturbance when it occurred. On the conditioning principle it would further be expected that the bodily reaction would be somewhat different, according to the kind of past experience the question was connected with. The simple conditioning theory can, however, hardly be the whole explanation of the lying reaction, for in laboratory experiments, such as some of those in the Indiana study, lying about rather trivial matters according to instruction did lead to enough differential reaction to yield a fairly good detection percentage. In fact, percentages of detection were so high as to suggest that lack of too great general stress is favorable to detection. The theory of conflict, following the psychoanalytic lead, would presume that a specially large physiologic disturbance would occur when two incompatible reaction tendencies are aroused at the same time. Whether there is a greater disturbance than the sum of the two separate excitations is questionable (3), but at any rate the two would be greater than one. Long habit would dispose the person to answer a critical question straightforwardly. On the other hand, when he is lying there are circumstances which arouse in him the tendency to denial. In the Indiana studies one experiment was based explicitly on this principle, but with the plan of distinguishing the two response tendencies by different sorts of muscular activity. The experiment gave good results, but not because it was possible to distinguish the two reaction tendencies. A better plan might have been to associate a "yes" answer with one hand and a "no" answer with the other. The purpose may be served, however, if the two response tendencies merely summate in the same place, and this could well be the mechanism by which the usual detection test works. On the conflict hypothesis, both reaction tendencies would probably need to be strong for good results. This suggestion again leads to a paradoxical recommendation: the situation must be so ordered that S makes a strong effort to conceal the infor- -162- mation. This strategy, opposite to that which might encourage admissions, may in fact be favorable to instrumental detection. The experiment, already described, which showed better detection when S was encouraged to think he might "beat the instrument" lends itself to this interpretation. If conflict is the basis of the large reactions that signify deception, then there is some danger of confusion with large reactions produced by strictly personal emotional problems. It is an established fact (see the preceding) that words touching on emotionally sensitized areas will produce large reactions, regardless of deception. A question touching on such an area might provoke a reaction greater than that produced by a mild conflict. A third possible basis of detection is the punishment, or better, threat-of-punishment principle. According to this idea a person will give a large physiologic response during lying because he anticipates serious consequences if he fails to deceive. In common language it might be that he fails to deceive the machine operator for the very reason that he fears he will fail. The physiologic reaction would be the consequence of an avoidance reaction which has a low probability of reinforcement, but not too low. If the theory has any validity at all it must be supposed that the physiologic reaction is associated with a state of uncertainty. It does seem that a lie told with a complete certainty of its acceptance would be unlikely to produce much reaction; and on the other hand we have the experimental evidence already mentioned that a lie told with no prospect of success whatever is also poorly detected. For good detection a situation may be necessary where S is willing to gamble on a rather long chance with some hope of success. To make this punishment theory cover the experimental results one needs to take "punishment" in a broad sense, since in experiments S quite often suffers no serious loss if he is detected. He does, nevertheless, lose the game which he is playing and possibly this is -163- countable as a punishment. Once again there seems to be all opposition between procedures designed to secure information and those that would lead to the best instrumental detection. Present knowledge is not sufficient to lead to a decision on which, if any, of these three theories is correct. Since the theories here discussed are not mutually contradictory, it is quite possible that all the conditions referred to are actually operative in some degree in the detection situation. In that event detection would be best when critical questions are associated with somewhat traumatic past events, when S is threatened with possible but not certain punishment as a result of lying, and when critical questions, perhaps by reason of the uncertain consequences, arouse conflicting reactions in S. Although direct, practical experience is lacking, some general findings of laboratory experiments are applicable. The relevance of many of the experiments for the criminal detection problem suffers from the fact that they involved no "crime. From their success, we may conclude that crime is not essential for lie detection. Studies directed specifically to these distinctive problems would be required for more reliable conclusions regarding the applicability of findings from previous experimentation to practical employments in intelligence interrogations.
Exhaust Collector electrode Detector Electrode housing Polarization leads Flame jet Hydrogen Air Column effluent Figure 29 buy prandin 2 mg without a prescription. However buy prandin 1 mg without a prescription, this valuable detector needs to be handled with a lot of skill and expertise so as to achieve wonderful and dependable results cheap 2 mg prandin otc. These heavy-negative-ions will have less mobility as compared to the electrons ; therefore, they will have no other coice than to unite with positive ions. Thus, the net result would be fewer ions and electrons available to migrate to the electrodes, thereby causing a marked and pronounced reduction in the standing current of the detector. Ultimately, this observed current decrease represent as the ‘signal’ of the electron capture detector. The metal block of the detector housing itself serves as a cathode, whereas an electrode polarizing lead suitably positioned in the centre of the detector housing caters for a collector electrode (anode). The radioactive source from a beta-emitter is introduced from either sides of the detector housing below the electrode polarizing lead. The column-effluent is passed into the detector from the bottom whereas its exhaust goes out from the top.

It may also be invariably termed as a nitrogen detector, a sulphur detector, a phophorus detector, and a halogen detector by virtue of the fact that its specificity in detecting organic compounds essentially containing these elements. If P- or S-containing hydrocarbons are ignited in a hydrogen-rich flame, it gives rise to chemiluminescent species spontaneously which may subsequently be detected by a suitably photomultiplier device. Two-charged electrodes serve as an electric field in the detector, the cathode becoming the collector electrode for the ions. The ion-current thus generated, that will be directly proportional to the ion concentration, then becomes the signal of the detector. Most frequently, a recorder of 1-10 mV full-scale deflection (~_ 10 inches) and having a response time 1 second or less is quite adequate. Essentially in a potentiometric recorder, the input signal is balanced continuously by a feedback signal making use of a servomechanism ; whereby a pen strategically connected to this system moves proportionally along the width of the chart paper, thus recording the signal, whereas simultaneously the chart paper keeps moving at a constant speed along its length. It carries a pen that writes along a span of about one inch, reserved for integrator on the recorder chart paper at the end. The zero line of the integrator moves almost parallel to the base line of the chromatogram and as soon as a peak appears on the recorder, the integrator-pen starts moving from right to left the vice-versa within its one-inch strip. Each one- inch traverse (counted along projection parallel to signal axis) is usually assigned a value of 100 counts ; the total number of counts corresponding to a peak are directly proportional to the area of the peak. The type of mechanical integrator* affords fairly good accuracy and precision ; and above all it is quite cheap. The main advantages of an electronic integrator are, namely : (i) Provides a much wider linear range, (ii) Changing the ‘attenuation’ is not required, and (iii) Offers highest precision in peak-area measurement. A commercially available*** fairly sophisticated computer system of such type are available abundantly that may be capable of undertaking load upto 100 gas- chromatographs with ample data-storage facilities. Generally, different components possess different response factors, application of which not only com- pensates for different detector response for different components but also take into consideration the other factors inherent with the procedure. However, these factors may be calculated by preparing a synthetic mixture absolutely identical to what is expected in the sample, and subsequently carrying out the gas-chromatography of this mixture exactly under idential experimental parameters as described in the method of analysis. In certain instances, like petroleum fractions, where it may be possible to assume that most of the components possess almost equal response factors, the area normalization formula in Eq. Graphical Approach : Many a times a ‘graphical approach’ as illustrated in Figure 29. In fact, the very purpose of this synthetic-blends is only to simulate a typical sample. Now, exactly equal (or known) amounts of both, the ‘synthetic blend’ and the ‘sample’are separately injected and chromatograms obtained. Thus, by actually comparing the areas of the desired component in both the chromatograms, the ‘unknown concentration’ may be determined by the following expression : A %X = (% X in synthetic blend) A′X where, A′X = Peak area of component X in the chromatogram of ‘synthetic blend’. However, this method is less accurate in comparison to the first two methods described earlier for quantitative analysis. It should be used judiciously if only a few components present in small concentration (i. Obviously, this part of analyis is as vital and critical as the gas chromatorgraphic part of analysis. Procedure : After having maintained the above mentioned experimental conditions for gas chromatog- raphy inject 2µl of solutions (1) through (4) sequentially. Observations : The assay is not valid unless the chromatogram obtained with solution (4) shows two principal peaks with a signal-to-noise ratio of at least 5. Calculations : Calculate the content of cetylalcohol and of stearyl alcohol from the chromatogram thus obtained with solution (1) by normalization. Identify the peaks by visual comparison with the chromatograms obtained with solutions (2) and (3) respectively. Cognate Assays A few other drugs can also be assayed by the same procedure and are stated below in Table 29.
