Behavior definition

Construct validation suggests that classification is central to and inseparable from theory. Classification of a disorder forms a representation of the theoretical construct that is needed for the basis of elaboration and testing of the theory. A classification system like the DSM provides a means of translating or operationalizing abstract theoretical ideas into more concrete (often behavioral) definitions. Testing the theory (classification system) rests on tests of its internal and external validity. These tests inform us about the adequacy of both the classification system and the theory. It is conceivabe that theory and classification evolve together over time. Theory creates an initial classification scheme that is evaluated and, when refined, informs us about theory. 

Unlike many designer-oriented specifications, data flow graphs are semantically clean and simple, thus forming an unambiguous behavioral definition suitable to interface to or exchange between synthesis packages, as well as to formal verification. 

Experimentally, such a square scheme (Scheme 1) can be deduced from a real CV titration. The fact that the guest s reduction gets easier is indicated by a shift toward more positive potentials. For oxidations, the shift would be toward more negative potentials. This redox-shift behavior definitively indicates that the complex gets more stable after the ET. Therefore, it is fair to use the formal redox potentials observed from the CVs as the true thermodynamic values in the square scheme that is, E. The H G stability can be independently measured using typical methods, allowing the stability of the reduced (or oxidized) complex (i.e., 3 " ) to be calculated from the three measured parameters 1, 2). 

Group discussions about practice observations might very well lead to changed or refined behavioral definitions. Additionally, it might be decided that some participants need more education and training about the observation process. When observers can use behavioral definitions and agree on the safe vs. at-risk occurrence of each behavior on 80 percent or more of the observation trials, you are ready for the next phase of DO IT— Observation. 

The acronym "SOON" depicted in Figure 8.8 reviews the key aspects of developing adequate definitions of critical behaviors to target for a DO IT process. You are ready for the observation phase when you have a checklist of critical behaviors with definitions that are Specific, Observable, Objective, and Naturalistic. We have already considered most of the characteristics of behavioral definitions implied by these key words, and examples of behavioral checklists are provided later in this chapter, as well as in Chapter 12 on "safety coaching."... 

Sample critical behavior checklist. Figure 12.10 depicts a comprehensive CBC for recording the results of a coaching observation. This kind of CBC recording sheet should be used after the participants (optimally, everyone in a particular work area) have derived precise behavioral definitions for each category and have practiced rather extensively with shorter CBCs. Such practice enables careful refinement of behavioral definitions and builds confidence and trust in the process. 

They found that an asymmetric carbon atom and a dipole moment in the molecular structure lead to a liquid crystal smectic C phase in which the molecular long axes are tilted from the layer normal of the smectic phase. Hence, ferroelectricity was expressed. The ferroelectric behavior definitely was confirmed by various measurements, including the D-E hysteresis [2].

Adsorbents such as some silica gels and types of carbons and zeolites have pores of the order of molecular dimensions, that is, from several up to 10-15 A in diameter. Adsorption in such pores is not readily treated as a capillary condensation phenomenon—in fact, there is typically no hysteresis loop. What happens physically is that as multilayer adsorption develops, the pore becomes filled by a meeting of the adsorbed films from opposing walls. Pores showing this type of adsorption behavior have come to be called micropores—a conventional definition is that micropore diameters are of width not exceeding 20 A (larger pores are called mesopores), see Ref. 221a. 

A third definition of surface mobility is essentially a rheological one it represents the extension to films of the criteria we use for bulk phases and, of course, it is the basis for distinguishing states of films on liquid substrates. Thus as discussed in Chapter IV, solid films should be ordered and should show elastic and yield point behavior liquid films should be coherent and show viscous flow gaseous films should be in rapid equilibrium with all parts of the surface. 

The explicit definition of water molecules seems to be the best way to represent the bulk properties of the solvent correctly. If only a thin layer of explicitly defined solvent molecules is used (due to hmited computational resources), difficulties may rise to reproduce the bulk behavior of water, especially near the border with the vacuum. Even with the definition of a full solvent environment the results depend on the model used for this purpose. In the relative simple case of TIP3P and SPC, which are widely and successfully used, the atoms of the water molecule have fixed charges and fixed relative orientation. Even without internal motions and the charge polarization ability, TIP3P reproduces the bulk properties of water quite well. For a further discussion of other available solvent models, readers are referred to Chapter VII, Section 1.3.2 of the Handbook. Unfortunately, the more sophisticated the water models are (to reproduce the physical properties and thermodynamics of this outstanding solvent correctly), the more impractical they are for being used within molecular dynamics simulations. 

In order to define how the nuclei move as a reaction progresses from reactants to transition structure to products, one must choose a definition of how a reaction occurs. There are two such definitions in common use. One definition is the minimum energy path (MEP), which defines a reaction coordinate in which the absolute minimum amount of energy is necessary to reach each point on the coordinate. A second definition is a dynamical description of how molecules undergo intramolecular vibrational redistribution until the vibrational motion occurs in a direction that leads to a reaction. The MEP definition is an intuitive description of the reaction steps. The dynamical description more closely describes the true behavior molecules as seen with femtosecond spectroscopy. 

By analogy with Eq. (3.1), we seek a description for the relationship between stress and strain. The former is the shearing force per unit area, which we symbolize as as in Chap. 2. For shear strain we use the symbol y it is the rate of change of 7 that is involved in the definition of viscosity in Eq. (2.2). As in the analysis of tensile deformation, we write the strain AL/L, but this time AL is in the direction of the force, while L is at right angles to it. These quantities are shown in Fig. 3.6. It is convenient to describe the sample deformation in terms of the angle 6, also shown in Fig. 3.6. For distortion which is independent of time we continue to consider only the equilibrium behavior-stress and strain are proportional with proportionality constant G ... 

At this point it is useful to compare the result we have obtained with the expected behavior of P(0) that we anticipated from the definition of this quantity ... 

The constant is not a tme partition coefficient because of difference, — V, includes the soflds and the fluid associated with the gel or stationary phase. By definition, IV represents only the fluid inside the stationary-phase particles and does not include the volume occupied by the soflds which make up the gel. Thus is a property of the gel, and like it defines solute behavior independently of the bed dimensions. The ratio of to should be a constant for a given gel packed in a specific column (34). 

Process Systems. Because of the large number of variables required to characterize the state, a process is often conceptually broken down into a number of subsystems which may or may not be based on the physical boundaries of equipment. Generally, the definition of a system requires both definition of the system s boundaries, ie, what is part of the system and what is part of the system s surroundings and knowledge of the interactions between the system and its environment, including other systems and subsystems. The system s state is governed by a set of appHcable laws supplemented by empirical relationships. These laws and relationships characterize how the system s state is affected by external and internal conditions. Because conditions vary with time, the control of a process system involves the consideration of the system s transient behavior.

Currendy, the Bauer-McNett classification and the QS test are the most widely used fiber classification techniques. Whereas there are quaUtative relationships between QS and BMN, there is no quantitative correspondence. It is readily understood that these standard tests do not provide accurate definition of the fiber lengths the classification also redects the hydrodynamic behavior (volumes) of the fibers, which, because of thek complex shapes, is not readily predictable. 

The systematic study of piezochromism is a relatively new field. It is clear that, even within the restricted definition used here, many more systems win be found which exhibit piezochromic behavior. It is quite possible to find a variety of potential appUcations of this phenomenon. Many of them center around the estimation of the pressure or stress in some kind of restricted or localized geometry, eg, under a localized impact or shock in a crystal or polymer film, in such a film under tension or compression, or at the interface between bearings. More generally it conveys some basic information about inter- and intramolecular interactions that is useful in understanding processes at atmospheric pressure as well as under compression. 

The basis of all bulk conveyor engineering is the precise definition and accurate classification of materials according to individual characteristics under a specific combination of handling conditions (1). Since the late 1960s there has been an extraordinary growth in research into the fundamental properties and behavior of particulate soHds. However, as of this writing, it is not possible to predict the handling behavior of a bulk soHds material relevant to conditions in a specific conveyor, merely on the basis of the discrete particle properties. 

Time-Dependent Cascade Behavior. The period of time during which a cascade must be operated from start-up until the desired product material can be withdrawn is called the equiUbrium time of the cascade. The equiUbrium time of cascades utilizing processes having small values of a — 1 is a very important quantity. Often a cascade may prove to be quite impractical because of an excessively long equiUbrium time. An estimate of the equihbrium time of a cascade can be obtained from the ratio of the enriched inventory of desired component at steady state, JT, to the average net upward transport of desired component over the entire transient period from start-up to steady state, T . In equation form this definition can be written as... 

A key limitation of sizing Eq. (8-109) is the limitation to incompressible flmds. For gases and vapors, density is dependent on pressure. For convenience, compressible fluids are often assumed to follow the ideal-gas-law model. Deviations from ideal behavior are corrected for, to first order, with nommity values of compressibihty factor Z. (See Sec. 2, Thvsical and Chemical Data, for definitions and data for common fluids.) For compressible fluids... 

To fuUy understand the mechanics of flow, the following definitions explain the behavior of various types of fluids in both their static and flowing states. 

To be able to systematically identify opportunities for reducing human error, it is useful to ask the question, What is human error One definition is that human error is an inappropriate or undesirable human decision or behavior that reduces, or has the potential for reducing safety or system performance (Rasmusssen 1979). There is a tendency to view errors as operator errors. However, the error may result from inadequate management, design, or maintenance of the system. This broader view which encompasses the whole system can help provide opportunities for instituting measures to reduce the likelihood of errors.
