HOW FAR SHOULD WE GENERALIZE?

Abstract— A conceptual model based on staffing theory was applied to previously collected survey data from a representative sample of American workers The model links organizational size, workload, work experience variables (felt responsibility and involvement, assessments of work associates), and work outcomes (job satisfaction, work self-esteem, stress symptoms) Path analyses indicated that the model fit data from all waged and salaried workers relatively well When the model was applied to subsamples of new and established employees and of employees from two contrasting occupational groups (professional-technical workers and operative workers), somewhat different patterns emerged The study illustrates the benefits of applying psychological theories across subdisciplines, as well as the limitations of generalizing research findings across different categories of workers We suggest that localized theories and fine-grained analyses of workplace events could help to make research more applicable to work settings     

Globalization or indigenization: New alignments between knowledge and culture

The pace, shape and meaning of development are cultural phenomena—fundamentally driven by the meanings people ascribe to their action, to the symbols they aspire to, and by the wider values contexts within which they are acting. However, people participating within the development process continuously confront a tension between the assertion of the cultural meanings of the local known social world and the assertion of the meanings of an idealized largely unknown social world that stretches beyond immediate experience, and that is particularly represented in commodity symbols and media images. Tension is therefore between indigenization or globalization. The product, greater valence of indigenization or globalization, results from the alternative ways in which tension between the two domains is resolved. In the modern social world access to knowledge, as well as the impact of knowledge embodied within technological artifacts, are key drivers in both the level of participation in development and the level of colonization of indigenized meanings by globalized frameworks of understanding. The current paper therefore focuses on the role of knowledge within the interactions between globalization and indigenization. The paper demonstrates that the general trend of development during the last half of the twentieth century has driven cultural change towards more globalized meanings and dependencies. The dynamics of technological access and change are centrally implicated. However, new opportunities are opening up at both local indigenized levels and within modernizing sectors, and the essence of these opportunities lies in capturing a cultural advantage. At the indigenous society level, a focus on capitalizing on indigenous technical knowledge can have enormous payoffs in terms of economic development outcomes. Meanwhile, a focus on linking local with modernizing sectors through bridging technologies and knowledge across indigenous and global cultures allows indigenous cultures to share in the economic benefits of modernization. And finally, a new wave of change is emerging in the modernized sector itself, opening up quite new opportunities for “small players”—whether they be small firms or small countries. The opportunities are set within change in the global orders of technology and science over the last five to ten years. What matters is the ability of these small players to be highly responsive, to capture knowledge flows through both technical and social capabilities of their people; in other words, global advantage follows from capture of local cultural strength.

Stereotyped movement disorder in an adult following acquired brain injury: Effect of environmental stimulation

In the present study, a naturalistic functional analysis procedure was used to assess the effect of environmental stimulation on the stereotypic behavior (body rocking) of an adult whose stereotypy appeared to be induced by an acquired brain injury. Environmental stimulation, operationalized in terms of both physical and social characteristics, resulted in only minimal changes in the occurrence of body rocking. Body rocking occurred in excess of 50% of the observations in all environmental stimulation conditions and in a naturally occurring baseline condition. To our knowledge, this is the first published report of a functional analysis of stereotypy associated with acquired brain injury.     

Case study: Examining the relationship between self-initiations of an individual with disabilities and directive behavior of staff persons in a residential setting

This case study examines the relationship between self-initiations of an adult woman with severe disabilities and the directive behavior of staff persons in a community residential setting. Hypotheses generated from functional assessment procedures indicated that (a) Susan's low self-initiations were very likely related to high directive behavior of staff persons, and (b) infrequent problem behaviors during the morning routine were maintained by escape from repeated staff demands. An intervention was implemented to enable Susan to increase self-initiation in choice and sequence of activities and simultaneously decrease staff directives. Results and discussion focus on the need for a contextual approach for addressing problematic situations and an affirmation of the effectiveness of the positive behavioral support technology for increasing adaptive behaviors in individuals with severe disabilities.     

Correlates of parent–child communication about specific sexual topics: A study of rural parents with school-aged children

Using data from 600 parents of children aged 5 to 18, and a context-oriented, developmental socialization conceptual framework, the interrelationships between parents' perceptions of themselves, their child, and their family relationships and the amount of parent–child discussion of 16 sexuality topics were explored. Canonical correlation analysis was used to demonstrate how circumstances and contexts influence the complexity of parent–child conversations for mother–daughter, mother–son, father–son, and father–daughter dyads. Results lend support to the conceptual framework used, as well as to previous studies of this topic area. The implications of these findings for parent–child relationships and for future research on parent–child communication about sexuality are discussed.     

Going beyond heart rate: autonomic space and cardiovascular assessment of mental workload

Psychophysiological assessment of pilot mental workload using heart rate should be augmented with an autonomic space model of cardiovascular function. This model proposes that autonomic nervous system influences on the heart may change with psychological processing in ways that are not evident in heart rate. A method of mental-workload assessment was proposed that used multiple psychophysiological measures of cardiovascular responsivity to derive the underlying sympathetic and parasympathetic information needed to represent the autonomic space for heart rate. Principal-components analysis was used to extract Sympathetic and Parasympathetic components from heart period, residual heart period. respiratory sinus arrhythmia, and Traube-Hering-Mayer wave in three experiments that manipulated perceptual/central processing and physical task demands. This initial evaluation of the method concluded that the autonomic components were valid and that the components had greater diagnosticity, and for some manipulations greater sensitivity, than heart rate. These results support the contention that the Sympathetic and Parasympathetic components provided increased precision for mental-workload assessment.     

Vibrotactile pattern discrimination and communality at several body sites

In a series of experiments, the effects of spatial layout on vibrotactile pattern perception were explored by testing the ability to discriminate between two sequentially presented patterns that share active elements in the same spatial locations. Two-dimensional displays were used in order to examine the functional relationship between discrimination performance and patterncommunality, defined as the sharing elements, on different body sites. Accuracy of discrimination judgments was inversely proportional to communality, regardless of the number of pattern elements. For compact arrays fitted to the finger, palm, and thigh, the effects of communality appeared equivalent. The similarity between finger and thigh functions is remarkable, considering the dramatic differences between these sites in receptor components and structure. When these data were compared with those from arrays with distributed contactors, performance was substantially better with well-separated pattern elements. Such findings help to explicate how information from apposed patterns can best be delivered to the skin through tactile communication systems.
