Weakly resolvable IV.3 search designs for the pn factorial experiment

A series of weakly resolvable search designs for the pⁿ factorial experiment is given for which the mean and all main effects are estimable in the presence of any number of two-factor interactions and for which any combination of three or fewer pairs of factors that interact may be detected. The designs have N = p(p–1)n+p runs except in one case where additional runs are required for detection and one case where $\text{(p?1)}\text{2}$ additional runs are needed to estimate all (p–1)² degrees of freedom for each pair of detected interactions. The detection procedure is simple enough that computations can be carried out with hand calculations.     

The central Europe experiment: Looking at persons and looking at objects

Gaze at objects, another person, and background was measured for fifteen dyads which constituted five different experimental groups in which task and situational factors were varied. The findings were that background stimuli had an unreliable effect on gaze; a very simple object relevant to the subject's task attracted a great deal of gaze and greatly reduced gaze at the other person. This effect was even stronger with a complex relevant object, where visual attention was almost completely transferred from the other person to the object. There was evidence of forces to avoid too much gaze at the other person. These findings suggested the possibility of postulating some new function of gaze in addition to information-seeking, or the possibility of an explanation in terms of the approach-avoidance model of gaze (Argyle & Dean, 1965).The authors are grateful to the S.S.R.C. for financial support.     

Disability and job stress: Implications for vocational rehabilitation planning

Because people with disabilities often experience an increased risk for physical and psychological complications of job stress, vocational rehabilitation professionals must be able to (a) identify individual and work-environmental risk factors for job stress and (b) design appropriate interventions to minimize those risk factors. The purpose of this article is to (a) present two models of occupational stress, (b) examine factors common to each of these models that are associated with employee health and well-being, and (c) suggest implications for rehabilitation planning.     

Individual Differences in Effectiveness of Cochlear Implants in Children Who Are Prelingually Deaf: New Process Measures of Performance

The efficacy of cochlear implants in children who are deaf has been firmly established in the literature. However, the effectiveness of cochlear implants varies widely and is influenced by demographic and experiential factors. Several key findings suggest new directions for research on central auditory factors that underlie the effectiveness of cochlear implants. First, enormous individual differences have been observed in both adults and children on a wide range of audiological outcome measures. Some patients show large increases in speech perception scores after implantation, whereas others display only modest gains on standardized tests. Second, age of implantation and length of deafness affect all outcome measures. Children implanted at younger ages do better than children implanted at older ages, and children who have been deaf for shorter periods do better than children who have been deaf for longer periods. Third, communication mode affects outcome measures. Children from "oral-only" environments do much better on standardized tests that assess phonological processing skills than children who use Total Communication. Fourth, at the present time there are no preimplant predictors of outcome performance in young children. The underlying perceptual, cognitive, and linguistic abilities and skills emerge after implantation and improve over time. Finally, there are no significant differences in audiological outcome measures among current implant devices or processing strategies. This finding suggests that the major source of variance in outcome measures lies in the neural and cognitive information processing operations that the user applies to the signal provided by the implant. Taken together, this overall pattern of results suggests that higher-level central processes such as perception, attention, learning, and memory may play important roles in explaining the large individual differences observed among users of cochlear implants. Investigations of the content and flow of information in the central nervous system and interactions between sensory input and stored knowledge may provide important new insights into the basis of individual differences. Knowledge about the underlying basis of individual differences may also help in developing new intervention strategies to improve the effectiveness of cochlear implants in children who show relatively poor development of oral/aural language skills.     

Risk Perceptions,General Environmental Beliefs,and Willingness to Address Climate Change

The research reported here examines the relationship between risk perceptions and willingness to address climate change. The data are a national sample of 1225 mail surveys that include measures of risk perceptions and knowledge tied to climate change, support for voluntary and government actions to address the problem, general environmental beliefs, and demographic variables. Risk perceptions matter in predicting behavioral intentions. Risk perceptions are not a surrogate for general environmental beliefs, but have their own power to account for behavioral intentions. There are four secondary conclusions. First, behavioral intentions regarding climate change are complex and intriguing. People are neither nonbelievers who will take no initiatives themselves and oppose all government efforts, nor are they believers who promise both to make personal efforts and to vote for every government proposal that promises to address climate change. Second, there are separate demographic sources for voluntary actions compared with voting intentions. Third, recognizing the causes of global warming is a powerful predictor of behavioral intentions independent from believing that climate change will happen and have bad consequences. Finally, the success of the risk perception variables to account for behavioral intentions should encourage greater attention to risk perceptions as independent variables. Risk perceptions and knowledge, however, share the stage with general environmental beliefs and demographic characteristics. Although related, risk perceptions, knowledge, and general environmental beliefs are somewhat independent predictors of behavioral intentions.

Recreational planning: an important component of career counseling for people with disabilities

Participation in recreational activities is a critical component of the career development process, providing opportunities for individuals to explore their interests and to develop work-related skills. Recreational participation also offers a healthy outlet for dealing with job-related and other life stressors. People with disabilities are often excluded from participation in recreational activities because of a multitude of barriers. This exclusion can seriously impede the career development of these individuals. This article explores the importance of recreational planning as part of the vocational rehabilitation process. The authors define inclusive recreation and discuss the implications of recreational planning in the various phases of rehabilitation.     

After the Interview

This article is concerned with after the interview, a strip of time (Goffman 1974, p. 10) between the end of the formal interview and the culmination of leave-taking rituals. Although there is a considerable and growing literature on qualitative interviewing (Arksey and Knight 1999; Kvale 1996; Rubin and Rubin 1995; Weiss 1994), and some corridor talk about the meaning of off the record post-interview comments, this topic has received little attention in the published literature (but see DeSantis 1980 and Wenger 2001). And we think it is an important one, since it illuminates the interviewee's interpretation of the interviewer and interview process, and highlights aspects of the meaning of the topic, and of the interviewer, to the respondent (which is, after all, the endpoint of the qualitative interviewing method). Further, the question of what constitutes after the interview throws into relief the question of what is an interview.
