Female business owners in industries traditionally dominated by males

This study examined selected demographics, personality traits, and job-related characteristics of females and males operating small businesses in traditionally male-dominated industries. Of the 56 participating businesses owners, all but 2 were Caucasian. Organizational characteristics were also observed. Significant gender differences were found in marital status, industry experience, age of firms, number of females hired, and effectiveness of communication scores.     

An Excel macro for transformed and weighted averaging

An Excel macro is presented for averaging spreadsheet data. The macro has several special features: (1) The data are weighted by the inverse variance of each datum to decrease the contribution-of noisy outliers. (2) There is a provision for a power or a log transform of the data before averaging. The rationale for transforming the data before averaging is discussed (3) The output includes the average value, its standard error, and the reduced chi-square that measures the goodness of fit (4) The standard error is corrected by a heterogeneity factor based on the reduced chi-square The averaging of data is rarely done properly, and the intent of this article is to clarify the issues and provide a tool that allows researchers to improve their averaging techniques.     

Size contrast as a function of conceptual similarity between test and inducers

In four experiments, the effect of the semantic relationship between test and inducing stimuli on the magnitude of size contrast in an Ebbinghaus-type illusion was explored. In Experiments 1 and 2, the greatest illusion was found when test and inducing stimuli were identical in shape and differed only in size. Decreased size contrast was found when inducing stimuli were drawn from the same category as the test stimulus, but were not visually identical. Even less size contrast was found when inducing stimuli were from a near conceptual category, with the least effect when they were drawn from a completely different category. In Experiment 3, it was demonstrated that even if test and inducing stimuli are drawn with identical geometric elements, the size contrast illusion is greatly reduced if they represent apparently different conceptual categories (through the manipulation of orientation and perceptual set). In Experiment 4, any geometric or spatial confounds were ruled out. These results suggest that size contrast is strongly influenced by the conceptual similarity between test and inducing stimuli.     

Prediction of Task-Related Arousal Under Conditions of Environmental Distraction1

The Arousability Predisposition Scale (APS) was used to assess individual differences in arousal that occur when a task is performed under conditions of environmental distraction. The APS is a brief (12-item) scale, that purportedly measures arousability as a trait or predisposition. To manipulate arousal experimentally, subjects performed a speeded search task under conditions of visual and auditory distraction. Pre- and postdistraction task measures of arousal were taken using Thayer's Activation-Deactivation Adjective Check List. The distraction task caused a general increase in arousal as compared to a control group who did not perform the task. Although there were no differences in pretest measures, subjects judged highly arousable on the APS showed a greater change in task-related arousal than subjects judged low on arousability, validating the usefulness of the APS as a measure of arousability under conditions of environmental stress.     

Attention and automaticity: Toward a theoretical integration

We sketch an initial version of a theory intended to account for the role of attention in the acquisition and expression of automaticity, and we test some initial predictions. The theory combines Logan's instance theory of automaticity and Bundesen's theory of visual attention, with Bundesen's theory determining what Logan's theory learns. We report four experiments that test the assumption that subjects learn what they report explicitly do not learn what they do not report explicitly. The experiments provide partial support for the predictions and encourage further development of the combined theory. Received: 4 September 1997 / Accepted: 12 January 1998     

"Scientific" Theology/"Theological" Science: Pannenberg and the Dialogue Between Theology and Science

Throughout his distinguished career, Wolfhart Pannenberg has sought to show that the Christian understanding of God is crucial to the pursuit of knowledge. As the essays in Beginning with the End indicate, Pannenberg has attempted to construct a bridge between theology and science via the idea of contingency and the concept of field. His interest in dialogue, however, arises out of a deeper theological foundation, which views theology as a public discipline and sees the human quest for truth as the quest for God. Although susceptible to criticisms that all objectivist approaches at-tract, this focus on "reasonable faith" provides a helpful point of departure for dialogue.     

Stress Inoculation Training For Impulsive Behaviors In Adults With Traumatic Brain Injury

A stress inoculation training program involving relaxation, self-instructional, and coping skills training was delivered to 5 persons with traumatic brain injury in an attempt to reduce the frequency of their impulsive behaviors. A multiple-baseline across subjects design was utilized to evaluate the effectiveness of the 10-week intervention. Dependent measures included frequency of impulsive behaviors as recorded by staff members at the residential facility where all 5 participants resided, ratings of role-play-probes, effectiveness ratings by the participants' rehabilitation counselors, and interview information obtained from the participants and their counselors. The data showed a small, but consistent reduction in impulsive behaviors across the 5 participants. Additionally, results indicated changes in role-play ratings did not correspond to changes in in-vivo behavioral frequency recordings for 4 of the 5 subjects. These findings suggest that individuals with moderate to severe impairments may require more salient behavioral contingencies and consistent cuing procedures to control their impulsive behavior.     

Logit models and logistic regressions for social networks: III. Valued relations

This paper generalizes thep* model for dichotomous social network data (Wasserman & Pattison, 1996) to the polytomous case. The generalization is achieved by transforming valued social networks into three-way binary arrays. This data transformation requires a modification of the Hammersley-Clifford theorem that underpins thep* class of models. We demonstrate that, provided that certain (non-observed) data patterns are excluded from consideration, a suitable version of the theorem can be developed. We also show that the approach amounts to a model for multiple logits derived from a pseudo-likelihood function. Estimation within this model is analogous to the separate fitting of multinomial baseline logits, except that the Hammersley-Clifford theorem requires the equating of certain parameters across logits. The paper describes how to convert a valued network into a data array suitable for fitting the model and provides some illustrative empirical examples.This research was supported by grants from the Australian Research Council, the National Science Foundation (#SBR96-30754), and the National Institute of Health (#PHS-1RO1-39829-01).
