exploring drug users' illness representations of hiv,hepatitis b and hepatitis c using repertory grids

Abstract

Hepatitis B and C viruses are more prevalent among injecting drug users than HIV. This study explored drug users' illness representations of hepatitis B and C using repertory grid methodology. Initially, nine drug users were presented with six elements including hepatitis B and C, and HIV. Constructs were elicited via the sequential form variation of the method of triads. Elements were rated on elicited constructs using a five-point scale, and analyzed using “Flexigrid”. In a second quantitative research stage, 52 drug users were presented with six elements and supplied constructs. Results of the first stage indicated participants were able to generate constructs relating to Leventhal et al.'s (1980) features of illness representations. Most constructs, however, were causal in nature. Participants perceived hepatitis B, C and HIV similarly along the causal component. This similarity on the causal component was largely replicated in the second research stage. Participants, however, distinguished HIV from hepatitis B and C along serious, cure and timeline features. Participants did not distinguish hepatitis B from hepatitis C. The implications of these results for health promotion are discussed.     

Whiteheadian Societies and Peirce's Law of Mind: Actuality and Potentiality in the Cosmic Process

Abstract

A more suitable philosophical position to counter the claims of scientific materialism re the nature of physical reality can possibly be found in combining the metaphysics of A.N. Whitehead and C.S. Peirce. Peirce postulated a habit-forming tendency or inbuilt potentiality of the cosmic process as a whole to move over time toward ever greater organization and more complex structure. But he is vague on how “the law of the mind” applies to nature below the level of human self-awareness. Whitehead's notion of actual entities (momentary self-constituting subjects of experience) as the “final real things of which the world is made up” logically allows for some primitive form of subjectivity with the requisite potentiality for habit-formation at all levels of existence and activity within nature. In addition, Whitehead's notion of structured societies made up of subsocieties with a “regnant” subsociety seems philosophically to justify the new emphasis on bottom-up rather than top-down causation in the emergence of more complex levels of existence and activity within the life-sciences.     

Incarnation and Semiotics: A Theological and Anthropological Hypothesis Part 2: Semiotics,Anthropology, and Religious Transformation

This is the second in a pair of articles in which we draw on C.S. Peirce's semiotics (theory of signs) to develop a new approach to the Christian concept of Incarnation. In Part 1 we used Peirce's taxonomy of signs to explore what it means to understand the life of Jesus as the embodiment of the quality of God within the fabric of the created order. In this article (Part 2), we explore some ways in which this semiotic approach to the Incarnation offers constructive opportunities in theological anthropology, and suggests some empirically testable hypotheses about human evolution.     

PEIRCEAN APPROACHES TO EMERGENT SYSTEMS IN COGNITIVE SCIENCE AND RELIGION

Cognitive science and religion provides perspectives on human cognition and spirituality. Emergent systems theory captures the subatomic, physical, biological, psychological, cultural, and transcendent relationships that constitute the human person. C. S. Peirce's metaphysical categories and existential graphs enrich traditional cognitive science modeling tools to capture emergent phenomena. From this richer perspective, one can reinterpret the traditional doctrine of soul as form of the body in terms of information as the constellation of constitutive relationships that enables real possibility.     

Psychometric and Piagetian intelligences: Toward resolution of controversy

Whether “psychometric” and “Piagetian” kinds of intelligence, as measured by instruments designed to measure these constructs, are the same or different is regarded as a question of whether they have the same or different courses of development with age. While factor analysis may not be fully adequate for investigation of this question, use of this technique with variables reflecting chronological age variation must involve elimination of the age effect in order to assess relations among the constructs measured. Humphreys and Parsons (1979) were justified in partialing out age in their reanalysis of a study by Stephens, McLaughlin, Miller, and Glass (1972), to show that the two constructs are highly correlated and possibly identical in the sample studied. Reanalyses of studies by DeVries and Kohlberg (1977) and by DeVries (1974) yield somewhat conflicting results on the identity between psychometric and Piagetian intelligences. The former study does not yield a convincing separation between them, whereas the latter suggests that they can be distinguished, though substantially correlated and both loaded with a general factor. Problems in further investigating the issue are discussed.     

Environments as reinforcer systems in the study of job satisfaction

This paper examined differences in the degree to which fifteen specific sources of job satisfaction were related to and predictive of the overall satisfaction of department chairmen in the six model environments proposed by Holland (1973). The fifteen specific sources of job satisfaction were regressed on overall satisfaction, separately for chairmen in each environment, through the use of incremental stepwise multiple regression procedures. The results indicated that the overall satisfaction of chairmen in these six environments was differentially related to unique weightings and combinations of the fifteen predictor variables. It was concluded that environments, composed of essentially similar groups of people in different organizations, serve as job satisfaction reinforcer systems in a manner similar to organizations as illustrated by Dawis.     

A comparison of attentional and control shift models of the performance of concurrent tasks

A concurrent verbal task was superimposed upon the performance of a practiced bimanual motor skill by right-handed Ss. Addition of the verbal task did not increase the total number of errors; however, a significant interaction between hands and conditions was observed. The right hand made significantly more errors under the verbal condition, while the left hand made non-significantly fewer errors under that condition. These findings were interpreted as supporting an attentional model rather than a model which proposes that addition of the verbal task causes control of the right hand to shift to the non-verbal right hemisphere.     

Stimulus control over sex-typed play in cross-gender identified boys.

Discriminative stimulus control over masculine and feminine sex-typed play behaviors was investigated in five boys, aged 5–8 yr, with “childhood crossgender identification.” Reliable observational measures of play were obtained with two sets of toys: (a) “dress-up toys” (girls' apparel vs boys' apparel), and (b) “affect toys” (maternal-nurturance play vs masculine-aggression play). With an ABA reversal intrasubject design, certain stimulus conditions (e.g., presence of father, mother, male, or female stranger) were found to be discriminative for reliable changes in sex-typed play. Sex-typed play was found to vary as a function of the social stimulus situation and as a function of the type of play response required. All children played predominantly feminine while alone in the playroom. While no single environmental stimulus was consistently discriminative for masculine play across children, at least one stimulus condition was found for each subject under which he played predominantly masculine.     

The measurement of cognitive vocational maturity

This report describes an instrument that was designed to measure an individual's level of cognitive vocational maturity in six areas: Fields of Work, Job Selection, Work Conditions, Education Required, Attributes Requited, and Duties. Procedures used in developing the item analysis research form and the final form of the instrument are described. Sample items from each subtest are presented. Kuder-Richardson reliability estimates for each of the six area subtests are presented for grades 6–9. Both criterion-related and construct validity data are presented. Pupils whose vocational choices were in agreement with their field of interest and their ability level scored higher on all subtests than pupils whose choices agreed neither with their interests nor with their ability level. Mean scores on all area subtests increase across grades levels, thus providing support for the claim that vocational maturity behaviors are developmental ones.
