Structural Flaws in the Bridge From Basic Research on Marriage to Interventions for Couples

In an article that received widespread media attention, Gottman, Coan, Carrère, and Swanson (1998) reported on a longitudinal study of newlywed couples and recommended major changes in the practice of marital therapy and education. Most notably, they called for the abandonment of interventions that promote active listening, they concluded that anger was not detrimental to marital outcomes, and they advocated an interaction pattern wherein wives raise issues more gently and husbands more readily accept wives' influence. Because of several methodological and conceptual shortcomings, the recommendations of Gottman et al. appear to us to be premature at best. We raise methodological concerns about the nonrandom selection of research subjects, failure to control for factors that may have differentiated couples initially, procedural issues regarding observational and physiological data, and ambiguity about statistical tests employed. We raise conceptual concerns about how the labeling of patterns affects the conclusions drawn and also about the use of correlational data to make strong causal inferences. We conclude that the article by Gottman et al. risks influencing couples and practitioners alike in a manner that, in our view, exceeds the scope and methods of the underlying research.     

Chemistry of growth medium and leachate from green roof systems in south-central Texas

Installation of intensive and extensive green roofs is becoming popular for reducing runoff from impervious surfaces in many cities around the world. Most studies on runoff quality from green roofs have been conducted in cooler northern climates. We examined the losses and gains of nutrients, cations and selected anions in planted and unplanted growth medium and compared these to initial growth medium (IGM) typically used for green roof modules in south-central Texas. Water extracts of growth medium and leachate from three replicates of unplanted growth medium and three planted species (Sedum kamtschaticum, Delosperma cooperi and Talinum calycinum) were examined. During the first 6 months after establishment we observed high losses of nitrate (25 to 44 mg kg⁻¹), dissolved organic carbon (DOC: 155 to 190 mg kg⁻¹) and nitrogen (DON: 9.0 to 11.2 mg kg⁻¹) and orthophosphate-P (1 to 2 mg kg⁻¹). Average leachate concentrations based on four rain events 6 months after establishment ranged from 0.3 to 6.6 mg L⁻¹ in planted modules and 6.3 mg L⁻¹ in unplanted modules for nitrate-N, 38 to 42 mg L⁻¹ in planted modules and 32 mg L⁻¹ in unplanted modules for DOC, 2.1 to 3.1 mg L⁻¹ in planted modules and 2.1 mg L⁻¹ in unplanted modules for DON and 0.27 to 0.37 mg L⁻¹ in planted modules and 0.40 mg L⁻¹ in unplanted modules for orthophosphate-P. We suggest that after the establishment of green roofs, leachate losses may contribute some runoff concentrations of nitrogen, carbon and phosphorous in urban areas.     

Advocacy and the SSSP: An analysis of research articles in social problems

This study examines the extent of advocacy in the research articles appearing in the journalSocial Problems from 1953–1992. The Society for the Study of Social Problems (SSSP) was founded in order to counter the mainstream scientism of the American Sociological Society. Becker’s presidential address to the SSSP in 1966 confronted the issue of advocacy and the consequences associated with research that does not explicitly “take sides.” The present study investigates advocacy inSocial Problems by means of a typology drawn from Becker’s address. The findings indicate that political advocacy has increased sharply over the duration ofSocial Problems. Implications of the findings are discussed in the context of value-neutrality and its relation to social problems research.     

Transformative Processes in Marriage: An Analysis of Emerging Trends

The study of conflict has dominated psychological research on marriage. This article documents its move from center stage, outlining how a broader canvas accommodates a richer picture of marriage. A brief sampling of new constructs such as forgiveness and sacrifice points to an organizing theme of transformative processes in emerging marital research. The implications of marital transformations are explored including spontaneous remission of distress, nonlinear dynamic systems that may produce unexpected and discontinuous change, possible nonarbitrary definitions of marital discord, and the potential for developing other constructs related to self‐transformation in marital research.
