Role-functionalism

The / -transition is a key feature and trademark in silks (Craig, 2003), whether the final product (Fig. 7) will be a high-performance fiber or will have other functions (Craig, 1997). The role, functionality, and diversity of each silk raise the interesting question whether selection pressures on the final fiber properties are mirrored (at, ultimately, the molecular level) in the precursor liquid proteins. Figure 8 shows SRCD spectra of six of the... [Pg.31]

Carboxypeptidase A"" (CPA, EC 3.4.17.1) is a proteolytic enzyme that cleaves C-terminal amino acid residues with hydrophobic side chains selectively. Several X-ray structures are available" The active site of CPA consists of a hydrophobic pocket (primary substrate recognition site) that is primarily responsible for the substrate specificity, a guanidinium moiety of Argl45 that forms hydrogen bonds to the carboxylate of the substrate, and Glu270, whose carboxylate plays a critical role, functioning either as a nucleophile to attack the scissUe carboxamide carbonyl carbon of the substrate or as a base to activate the zinc-bound water molecule, which in turn attacks the scissile peptide bond ". However, semiempirical calculations had shown that the direct attack of... [Pg.15]

For many people, physical health problems limit role performance. Occasionally, mental disruption can impinge on role functioning, but measures of this health dimension seldom detect mental or emotional problems because patients seldom consider role limitations unless they are asked about them explicitly. Some questionnaires ask specifically about limitations of role function due specifically to personal or emotional problems, in addition to those due to physical health problems. [Pg.421]

Role functioning scales usually measure global, role-level disability indicators to capture disability in paid work and/or other activities. However, for some applications, these may be relatively course, distinguishing a limited range of disability levels. Recently, researchers introduced a more detailed measure of work productivity assessing on-the-job impact of chronic conditions and treatment. [Pg.421]

Standardized measures capturing patient perspectives on their physical functioning, social and role functioning, mental health, and general health perceptions are likely to become more acceptable as an additional piece of evidence on which providers and their patients can make... [Pg.424]

The study of HRQOL requires a multidimensional approach. Assessments must include components that evaluate, at a minimum, the health concepts of physical functioning, social and role functioning, mental health, and perception of general health. In addition, the full continuum of these concepts must be included, from the most limited to the healthiest. Approaches to capture HRQOL data include the self-administered questionnaire, personal interview, telephone interview, observation, and postal survey. The assessment instruments must possess acceptable reliability, validity, and sensitivity, and the investigators and the participants must accept them. Psychometrics... [Pg.424]

C3 is based on the state diagram and the activity diagram of UML. As these diagrams do not cover the requirements for modeling cooperative work processes [221], additional elements and concepts have been added to C3, such as the blob element of the Higraphs [719], a modified subset of Role-Function-Activity Nets [872], and some concepts of Task Object Charts [1069]. [Pg.91]

C3 is intended for users below expert-level. The language is not meant for finegrained models, but rather to describe unstructured and partially structured activities and work processes. C3 inherits from other languages, in particular UML activity diagrams. Task Object Charts, and state charts. Also, a modified subset of Role-Function-Activity nets (It,I A nets, [872]) for the representation of information flows and cooperation partners has been adopted. [Pg.134]

In the clinical picture of an OPC poisoning, symptoms of CNS impairments (mentality modifications, tremor, periodic clonic/tonic convulsions, etc.) play a leading role. Functional impairments of different CNS parts (encephalon and spinal cord) under influence of OPC are associated with the cerebral ChE activity inhibition and the accumulation of ACh mediator in central synapses. It should be taken into consideration that permeability of the hematoencephalic barrier (HEB) differs in various CNS parts thereby the same substance inhibits ChE in a different degree in various cerebral structures. Along with the factor of selective permeability of various HEB areas and not identical ChE distribution within the brain, one cannot leave out of account selectivity in OPC effects of their own OPC can exhibit higher activity towards a certain cerebral structure. [Pg.158]

Although extrapolation to humans has not been reported, P450 7B1 is considered to be a neurosteroid hydroxylase and have a potentially important role . Functional polymorphisms in the human CYP7BI gene have not been reported, but have been postulated to lead to severe hypercholesterolemia and neonatal liver disease . [Pg.441]

Role/Function of NGF. NGF is a neurotrophic protein molecule essential for the growth and survival of sympathetic and small-diameter afferent neurons (nociceptors) [27, 28] and is involved in neuronal function and plasticity [24]. NGF belongs to the neurotrophin family, which also includes the brain-derived neurotrophic factor (BDNF), glial-derived neurotrophic factor (GDNF), neurotrophin-3 (NT-3), and neurotrophin 4/5 (NT-4/5) [29, 30]. [Pg.1175]

The functionalist idea of realization has been implemented in at least two different ways. 1 have in mind the distinction between filler-functionalism and role-functionalism. 1 will focus here exclusively on these two ways of implementing the functionalist idea. As we will see in due course, the filler-functionalist implementation of the notion of realization is unavailable to the NRP theorist, for given that implementation, the claim that every mental event is realized by a physical event entails that every mental event is identical with a physical event. The role-functionalist implementation does not have that implication. But there are, I maintain, grounds for skepticism that the role-functionalist view of mental events is compatible with mental events being causes. Those grounds, moreover, are independent of the truth of physical closure and the physical effects principle and thus do not presuppose them indeed, the concerns are independent of whether our world is fundamentally physical but of this, more in due course. To anticipate, then, I will argue that appeal to the filler-functionalist notion realization will not enable NRP theorists to offer an account of the place of mental events in nature that meets condition (i) and that there are... [Pg.71]

Let us turn, then, to the role-functionalist implementation of the notion of realization. NRP theorists typically appeal to it, and so are typically role-functionalists. According to type role-functionalism, a mental event type M is a second-order event type it is the event type of undergoing an event of some type or other tokens of which would play a certain role R, which includes a causal role. ° (The account of R is as before.) If an event type is such that tokens of it would play R, then it is a realizer of M. If there is more than one event type tokens of which would play R, then Af is multiply realizable. Type role-functionalists can maintain, without commitment to type physicalism, that whenever a mental event type is realized, it is realized by some physical event type or other. On this role-functionalist view, the... [Pg.75]

Thus, even on a property exemplification conception of events, type role-functionalism can be combined with token physicalism (for events). Type role-functionalism, you will recall, is the view that a mental event type M is the event type of undergoing an event of some type or other tokens of which would play a certain role R. It is open to a type role-functionalist to maintain that every instance of an Af type event is a physical event. The property of being an M type event (an event tokens of which would play R) would be a characterizing property of an event rather than a constitutive property. A physical event (an event with a constitutive physical property) would be an instance of M in virtue of the fact that it plays role R. This combination of type role-functionalism and token physicalism is compatible with mental events being causes even given physical closure and the physical effects principle, for it entails that every mental event is a physical event. [Pg.79]

I won t pursue these matters here. The reason is that NRP theorists must reject this combination of type role-functionalism and token physicalism, for they deny that mental event tokens are identical with physical event tokens. Mental event tokens, they hold, are exemplifications of functional properties and are not identical with exemplifications of physical properties that realize the functional properties. Let us see how to spell out their idea using Kim s theory of events. The idea is that functional properties will be constitutive properties of events rather than characterizing properties of events. Thus, let T be a functional property and P be one of its physical realizers. An exemplification of T by x at t will be the event [x, F, t] the property of which the event is an exemplification will be functional property F. If property T is realized on the occasion in question by P, then X will have Fat t in virtue of having Pat t. It follows that x, P, t] occurs and has role R, and indeed x, P, t will realize x, F, t by virtue of [x, P, t] having R But although [x, P, t R, it is nevertheless the case that x, P, t + x, F, t]. The reason is that P F. Thus, if there are functional properties and they are constitutive properties of events, then exemplifications of functional properties are not identical with exemplifications of their physical realizers. [Pg.81]

An intermediate enzyme-coenzyme A complex in which the energy of the thioester bond is preserved has been demonstrated. Here the coenzyme A thioester is involved in a transfer reaction quite different from its usual acyl donor role. Functionally this enzyme allows metabolically generated coenzyme A derivatives to be utilized directly for carboxylic acid activation, without intermediary formation of nudeoside triphosphates. [Pg.326]
