Re-thinking the relationship between theory and practice: Practitioners as map-readers, map-makers—or jazz players?

Theory is a major element in professional knowledge. Doubts about its value reported by practitioners raise questions at a critical juncture in the careers field about the relevance of prevailing theories and how they are approached. The topic of the relationship between theory and practice is a sensitive one in the debate on competencies and an illuminating one in that on post-modernism. As recent studies demonstrate, problems in integrating theory and practice arise in training and may persist, but experienced practitioners achieve 'fusion' between them and become 'practical theorists'. Practice is improvisatory, and is refined by frameworks provided by theory, critical thinking and 'reflective practice'. However, theories are often tardy or irrelevant, and practitioners also need to be able to carry out their own research, including action research. This has implications for initial and in-service training, supervision and policy, and for the relationships between researchers, theorists and practitioners.     

The relationship between sex role attitudes and attitudes supporting marital violence

This study explored the relationship between attitudes toward sex roles and attitudes endorsing the legitimacy of physical force by men in the marital relationship. Approximately 40% of this sample of 300 college undergraduates were black, allowing black-white comparisons on these variables as well. The results support a sociocultural analysis of spouse abuse. A moderately strong positive relationship was found between traditional sex role preferences and attitudes supporting the use of physical force. In addition, men were found to hold more traditional sex role attitudes than women and were more likely to endorse the use of physical force in the marital relationship. Whites were found to be more traditional in their sex role attitudes than blacks, but no racial differences were found with regard to attitudes endorsing physical force. Further analysis revealed that traditional sex role attitudes were the most powerful predictor of attitudes supporting marital violence, while race and sex played a relatively unimportant role. Implications for spouse-abuse prevention program are discussed.     

Stability of personality self-ratings over 30 years: evidence for an age/cohort interaction

An investigation was made of the hypothesis of Bloom (1964) and others that the stability of personality is greater among older than younger adults. The subjects were 459 men in two cohorts, followed from 1947 to 1977 as part of a longitudinal medical study. Self-ratings were obtained over the 30-year period on 15 item-factor scales from the Minnesota Multiphasic Personality Inventory and on two higher order factors. There was no selective attrition in the sample with respect to baseline personality scores. Thirty-year uncorrected stability coefficients ranged from .08 to .88 across the two cohorts. There was substantial evidence of greater stability on many traits in the older than in the younger age/cohort group. Furthermore, in late adulthood, traits related to the higher order factor Constraint were more stable than were traits related to Positive vs. Negative Affectivity. The study is not a definitive test of Bloom's hypothesis because cohort and age effects are confounded. However, the results are supportive of the hypothesis and the study improves on existing research in a number of ways.     

The death and transfiguration of career-and of career guidance?

The predominant understanding of career in the industrial era has focused on progression within hierarchical work organisations. With the move into a post-industrial era, the possibility of such careers is rapidly receding. The concept of career, however, has always been broader than this, and other aspects of it are now claiming increased attention. They focus more upon individual experiences in terms of development in learning and work throughout life. The role of career guidance in relation to such experiences is potentially of much greater social significance. A number of implications for career guidance provision and practice are discussed.     

Career in context

Mainstream career theories have been criticised for their scanty conceptualisation of the environment that influences individuals' careers. There are few foundations upon which to build an appropriate conceptualisation of the dramatically changing environment of career today. The implications of Pepper's contextualist world hypothesis are discussed. Compared with orthodox approaches, the world as seen from this perspective is as different as the Internet is from a library; its understanding of the environment, and indeed career, is also significantly different. The contextualist perspective upon career research, theory and practice is outlined and the possibility of its adoption in the mainstream of the career field is explored     

Inherited predisposition to alcoholism: characteristics of sons of male alcoholics

Sons of male alcoholics (SOMAs) are at markedly heightened genetic risk for the development of alcohol abuse. Study of SOMAs could therefore conceivably increase the efficiency of research aimed at uncovering those heritable factors that predispose to alcoholism. SOMAs manifest observable behavioral, cognitive, and psychophysiological abnormalities while sober and react idiosyncratically to alcohol intoxication. They are most commonly described as conduct disordered and hyperactive, appear heir to a variety of deficits in verbal and abstract cognition, and perform more poorly in the academic environment. SOMAs are characterized by abnormal patterns of cued psychophysiological response, and appear more sensitive to the putatively reinforcing aspects of alcohol intoxication. Various methodological weaknesses permeate the relevant literature. Some straightforward improvements are suggested.     

Instrumentation for an electrocutaneous communication device

The device described is a prototype that uses spatiotemporal resolution for electrocutaneous stimulation. Signals initiated through a keyboard activate a matrix of four electrodes that may be applied to the fingers, forearm, abdomen, back, or other parts of the integument. The instrumentation described includes a pulse generator, the active time and delay time controls, the control of the total length of a pulse train, and the constant-current generators whose output is fed into the electrodes. This device may be used as an interface with an alphanumeric device (e.g., a calculator or computer) and as a basic instrument in research investigating the spatial and temporal resolving capacities of the skin senses.     

The effects of spatial frequency overlap on face recognition

The effects of spatial frequency overlap between pairs of low-pass versus high-pass images on face recognition and matching were examined in 6 experiments. Overlap was defined as the range of spatial frequencies shared by a pair of filtered images. This factor was manipulated by processing image pairs with high-pass/low-pass filter pairs whose 50% cutoff points varied in their separation from one another. The effects of the center frequency of filter pairs were also investigated. In general, performance improved with greater overlap and higher center frequency. In control conditions, the image pairs were processed with identical filters and thus had complete overlap. Even severely filtered low-pass or high-pass images in these conditions produced superior performance. These results suggest that face recognition is more strongly affected by spatial frequency overlap than by the frequency content of the images.     

Face recognition is affected by similarity in spatial frequency range to a greater degree than within-category object recognition

Previous studies have suggested that face identification is more sensitive to variations in spatial frequency content than object recognition, but none have compared how sensitive the 2 processes are to variations in spatial frequency overlap (SFO). The authors tested face and object matching accuracy under varying SFO conditions. Their results showed that object recognition was more robust to SFO variations than face recognition and that the vulnerability of faces was not due to reliance on configural processing. They suggest that variations in sensitivity to SFO help explain the vulnerability of face recognition to changes in image format and the lack of a middle-frequency advantage in object recognition.     

Evidence-based treatment of stuttering: II. Clinical significance of behavioral stuttering treatments

An evidence-based framework can be described as an empirically-driven, measurement-based, client-sensitive approach for selecting treatments. It is believed that using such a framework is more likely to result in a clinically significant outcome. For this paper, a clinically significant outcome was defined as a meaningful treatment change. It was suggested that there are at least three groups for whom a treatment's outcome is meaningful. These groups include clinicians/clinical researchers, the clients, and relevant others who have some interest in the outcome (e.g., parents of a child who stutters). The meaning and measurement of clinical significance was discussed for each of these three groups, based on research from the behavioral stuttering treatment literature. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to (1) broadly define a clinically significant outcome and identify some of the groups who are interested in such an outcome and (2) describe how clinical significance has been evaluated in stuttering treatment within an evidence-based framework.
