FORTRAN subroutine for an EEG feedback digital filter

A method of constructing digital filters is outlined and illustrated in an application for research uses of EEG feedback. The method is based on least squares estimation with geometric weighting. Old data in the time series are discounted according to age, as new data arrive. Recurrence relations are used, allowing the computations to be performed in real time. A FORTRAN digital filter is formulated that simultaneously estimates (1) the spectral power in a band centered at a target frequency, (2) the total spectral power, and (3) the dominant frequency.     

The family void: treatment and theoretical aspects of the synchronous family paradigm

The synchronous paradigm is a model of families whose members remain uninvolved and disconnected from each other yet somehow maintain relatively unvarying or even rigid patterns of behavior. In the synchronous paradigm, calm agreement and harmonious unity of action are valued above all. The concept of synchronous operation was first formulated by Constantine to solve certain theoretical problems growing out of the work of Kantor and Lehr. The theory has been elaborated upon through linkages established with other clinical and theoretical models of family dysfunction. Clinical experience in treating synchronous families has now contributed more detailed and practical understanding. Clinically, disabled synchronous families may present as bland, boring, or even death-like. They may have considerable difficulty accommodating to necessary developmental changes or to the demands of life crises, employing a variety of strategies to maintain the appearance of synchrony at the expense of adaptation. Their ability to ignore change and to absorb interventions can tax the abilities of even the most creative and energetic therapist. On the other hand, the quiet efficiency of the family and the social sensitivity of its members can be strong assets. Awareness of their strengths and special vulnerabilities can help the family therapist work more effectively with synchronous families.     

Twenty years of family therapy in Israel: a personal journey

This article is a personal statement of my beliefs and practice of family therapy, from the time I first introduced the concept to Israel over twenty years ago to the present day. It reflects the evolution and changes in my clinical work against the background of major developments in the field of family therapy.     

PERSONAL SPACE AMONGST ARABS AND AMERICANS*

Personal space zones were examined amongst Arab and American university students by jointly varying degree of acquaintanceship and sex of subject. Overall, there were few differences between Arab and American males. Arab females, however, showed dramatic differences in comparison to American males and females and to Arab males. Arab females kept male friends very far away relative to female friends. Indeed, male friends were kept almost as far away as male strangers.     

SOCIAL DISTANCE NORMS IN CANADA: EFFECTS OF STIMULUS CHARACTERISTICS AND DOGMATISM*

The effects of stimulus person characteristics (viz., race, occupational status, religion, and nationality) and the respondent's level of dogmatism upon the social distance responses of a sample of Canadian university students were examined. Occupational status, race, and nationality of the stimulus person emerged as significant determinants, with occupational status being by far the most important. Dogmatism was also correlated with social distance responses. Highly dogmatic persons, but not those low in dogmatism, focused on occupational status in deciding acceptable bounds of intimacy with others. Several explanations for the prominence of occupational status as a social distance cue are discussed. As well, directions for future research into social distance norms in Canada are suggested.
