BALANCED DESIGNS FOR ROW-AND-COLUMN EXPERIMENTS WITH TWO NON-INTERACTING SETS OF TREATMENTS, ONE SET NOT BEING APPLIED TO ALL THE ROWS1

This note gives and discusses balanced row-and-column designs for experiments with two non-interacting sets of treatments, one set not being applied to all the rows. These designs are potentially useful for occasions when trees that have tested one set of experimental treatments are needed for testing a second set before the residual effects of the first have become negligible, but when the experimenter wishes to apply the second set to only some of the rows. The designs are appropriate if the residual and new effects do not interact.     

An assessment of the quality of developmental day center playgrounds for exceptional children

This study assessed the playgrounds of developmental day care centers and compared them with playgrounds of regular certified day care centers. Twenty playgrounds, randomly selected from the listing of developmental day centers, were compared with a matched sample of 20 playgrounds from certified day care centers in one state. A revision of Frost's Playground Rating System (1978b) was employed to rate the two groups of playgrounds on content, safety, and function. Data were analyzed using an analysis of variance technique. The quality of developmental day center playgrounds for exceptional children was inferior to that of regular day care center playgrounds in terms of playground content. No significant differences were noted on safety or function.     

Wirth,Whiskey, and WASP's: Some Consequences of Community Size for Alcohol Use*†

Several themes in Wirth's “Urbanism as a Way of Life” generate the prediction that alcohol use (versus nonuse) will be more widespread among residents of urban areas. Multiple regression analysis of data from two recent national polls (1966, 1968) reveals support for this prediction. With eight other key sociological variables simultaneously controlled, the greater the urbanism of a community (measured in terms of community size), the greater the proportion of alcohol users it contains. To make certain that this association is due to urban conditions (as opposed to merely the absence of rural forces which encourage abstinence), the effects of rural forces are reduced by omitting the most rural categories of the community size measure of urbanism, and the data are reexamined. The association still persists, basically because of the larger proportion of middle to upper status, white, and Protestant alcohol users in the more urban areas.     

The impact of gender on gambling attitudes and behavior

Researchers have often attributed the consistent relation of gender and gambling behavior to gender role socialization. If they are correct, gender should affect different sets of gambling attitudes in a manner consistent with at least three aspects of gender role socialization: a double standard of morality, a guardian of the hearth role for women, and a dualism of orientations. A survey measuring gambling attitudes and behavior was sent to a sample of residents in North Dakota after legalization of several games of chance (e.g., blackjack). Gender affects behavior but only some of the specified attitudes. These mixed results may reflect changes in gender role socialization and the increasing legalization of gambling.     

Sexual orientation, behavioral plasticity, and evolution

The argument of Futuyma and Risch (1983/1984), that the homosexual orientation is not a distinct, evolved, reifiable trait with a genetic basis, but an expression of universal sexual and emotional drives, has validity. Yet it does not answer the question of why the development of sexual orientation has evolved to be so flexible as to allow an individual to become homosexual. It is proposed that this flexibility may result from the evolution of the capacity to learn, the complexity of the central nervous system, and behavioral plasticity in general. This theory fits the known literature better than all other evolutionary explanations of homosexuality and has interesting implications for the evolution of altruistic behavior in humans.     

A framework of managerial promotion in a lifetime employment organization: The D bank

From existing formal personnel policies in a Korean bank, a set of internally consistent career system properties are logically inferred for an organization with the strategic human resource objective of lifetime employment. It is argued that the policy emphasis accorded particular functional personnel activities is inherent in the choice of human resource utilization strategy. It is recognized, however, that certain contextual features (e.g., the legal environment, cultural norms) may either constrain or facilitate the choice.     

MARITAL PARADIGMS: COMPATIBILITY, TREATMENT, AND OUTCOME IN MARITAL THERAPY

Marital paradigms comprise the guiding images that serve as reference models for a couple's relationship. Such individualized images can be understood as variations on a small set of basic themes. An understanding of clients' marital paradigms can help foeus treatment on the most appropriategoals usingapproaches and techniques that are most effective for a particular couple. An unselected group of 103 couples seen in systems-oriented marital therapy were reviewed, to identify outcome and treatment issues as a function of marital paradigm. Based on outcome criteria that took marital paradigm into account, 92% of 38 cases where both partners identified with the same basic paradigm were judged to be treatment successes, while only 60% of the cases where the partners identified with different paradigms could be considered successful outcomes. Clinical approaches based on experience with marital therapy conducted within a paradigmatic framework are presented.
