Pornography and Marriage

We used data on 20,000 ever-married adults in the General Social Survey to examine the relationship between watching pornographic films and various measures of marital well-being. We found that adults who had watched an X-rated movie in the past year were more likely to be divorced, more likely to have had an extramarital affair, and less likely to report being happy with their marriage or happy overall. We also found that, for men, pornography use reduced the positive relationship between frequency of sex and happiness. Finally, we found that the negative relationship between pornography use and marital well-being has, if anything, grown stronger over time, during a period in which pornography has become both more explicit and more easily available.     

The Times They Are A‐Changin’: Declining Immigrant Employment Opportunities in Scandinavia1

This article compares and contrasts male immigrant labor market experiences in Sweden and Denmark during the period 1985–1995. Using register‐based panel data sets from Sweden and Denmark, a picture of the employment assimilation process of immigrants from Norway, Poland, and Turkey is presented. The comparative approach shows that immigrants in Sweden and Denmark experienced similar declines in employment prospects between 1985 and 1995 despite quite different developments of aggregate labor market conditions. A possible explanation is that the changing organizational structure – toward more flexible work organization – has resulted in a decrease in the attractiveness of immigrant employees due to the increasing importance of country‐specific skills and informal human capital.     

Strategic planning for British nuclear fuels Ltd.

This article presents an account of the current state of planning in a Government - owned company. The author describes differences he sees between the planning process in his enterprise and those which are outlined in many planning texts.Since the company is relatively new, the author makes no claims for the success of the total planning operation as he describes it. However, he does indicate areas where advances have been made.Among these are proving the validity of the chosen planning system; the derivation of objectives from the planning process rather than as a starting point, and the acceptance of the planning operation by Top Management.     

Evaluating Risk Communication about Fish Consumption Advisories: Efficacy of a Brochure versus a Classroom Lesson in Spanish and English

Presentation format can influence the way target audiences understand risk-related information. Brochures or fish fact sheets are the methods traditionally used by state agencies to inform the public about fish consumption advisories and the risks from consuming fish. This study examines the efficacy of presenting information about the risks from consuming contaminated fish and shellfish in two different formats: a brochure and classroom presentation. The two instruments were developed and tested in Spanish and English, reflecting the local ethnic composition in the Newark Bay Complex. The instruments were tested on women of child-bearing age at the Women, Infants, and Children Center in Elizabeth, New Jersey. Detailed diagrams were used in both presentations, including contaminated fish species, fish preparation methods, and food chain bioaccumulation and transmission to the fetus. There were few language-related differences in the efficacy of the classroom lesson, and the main ideas were understood by both groups. Where there were significant differences in understanding about the risks from consuming fish or crabs from the contaminated waters of Newark Bay, in all cases the women exposed to the classroom lesson had a better understanding than those who read the brochure. Ninety-six percent of the women who heard the lesson understood that it was unsafe to eat fish from the port, compared to 72% of those reading the brochure. Both formats succeeded in imparting information to most women about the area under advisories, the fish species under advisories, and transmission of toxins to the fetus. Information on fish preparation was recalled less clearly, partly because women were asked to relate methods to reduce the risk from consuming fish from 11 presented, and most recalled only two or three of the list. The advantages and disadvantages of conducting short classes to women of child-bearing age are discussed.     

Effect magnitude: A different focus

The role of measures of effect magnitude in the research enterprise is examined. Measures of effect magnitude are used for four purposes: (a) to estimate the sample size required to achieve an acceptable power, (b) to integrate the results of empirical research studies in meta-analyses, (c) to supplement the information provided by null hypothesis significance tests, and (d) to determine whether research results are practically significant. The advantage of focusing on effect magnitude and practical significance instead of statistical significance and p values is illustrated with an example.
