Microbial Sampling and Data Interpretation for Problematic Buildings: Considerations for Construction Related Environmental Claims

Bioaerosol data is often used in cases of building mold infestation alleging damage or adverse health effects upon occupants, despite the lack of consistent sampling and analytical protocols and numerical health-based standards. The most fundamental problem in these scenarios is defining a “significant” difference between a suspect indoor environment and the reference environment, regardless of the type of sampling and analysis utilized. Data interpretation focused upon differences in absolute numerical concentrations of fungi is subject to wide differences in expert opinion. On the other hand, an objective quantification of differences can be expressed in terms of probability and better meets criteria established in evidentiary rules.     

Sustainable governance of natural resources and institutional change–an analytical framework

This article presents a conceptual framework for analysing the governance of natural resource use, as governance is often the primary issue when natural resources are overexploited and degraded. It addresses both spontaneous and active governance, including institutional change induced by development co‐operation. Drawing on existing frameworks of institutional analysis, fundamental modifications are presented to adapt the concept to the context of international co‐operation, and to include dynamic aspects of institutional change as well as multiple actor interactions. Tested in several case studies, the framework was found suitable and relevant for use in project planning and evaluation, as well as for comparing governance issues across cases in a conceptually rigorous way.

Adolescent depression: Why more girls?

Although there has been evidence for some time of a sex difference in depression, relatively little research has examined the developmental process by which women come to be at greater risk than men for depression. In this paper, the developmental pattern of depressed affect is examined over early and middle adolescence, with a special focus on the patterns of boys as compared to girls. In addition, a developmental model for mental health in adolescence is tested for its power in explaining the emergence of gender differences in depression. Longitudinal data on 335 adolescents randomly selected from two school districts were used to test the hypotheses. Results revealed that girls are at risk for developing depressed affect by 12th grade because they experienced more challenges in early adolescence than did boys. The sex difference in depressed affect at 12th grade disappears once early adolescent challenges are considered.This research was supported in part by grants MH30252/38142 to A. Petersen.

Approach and avoidant coping: Implications for adolescent mental health

We conducted a short-term longitudinal study examining the structure of coping behavior and the relationship between coping style and depression during adolescence. The sample consisted of 603 adolescents in Grades 6–11 who were surveyed in the fall of 1989 and again in the fall of 1990. A two-dimensional model of coping was found using confirmatory factor analysis with the factors being approach and avoidant coping. Four cross-sectional and seven longitudinal coping groups were formed to explore group differences in depression. Approach copers reported the fewest symptoms of depression, while avoidant copers reported the most. Subjects who changed over time from approach to avoidant coping evidenced a significant increase in depressive symptoms, whereas subjects who switched from avoidant to approach coping displayed a significant decrease in depression over a one-year period. These findings imply that adolescents who are able to elicit social support, engage in problem solving, and cognitively restructure events within a positive light are more likely to successfully negotiate the challenges of adolescence.This research was supported by a grant from the William T.

Contraceptive behavior in adolescence: A decision-making perspective

The contraceptive behavior of adolescent girls was viewed from a decision-making perspective. A semistructured interview protocol was used in interviewing 120 girls aged 12–19 in three clinics (Teen Family Planning, Prenatal, Pediatric Acute Care) at Michael Reese Hospital and Medical Center on (1) demographic in formation; (2) sexual and obstetric history; (3) contraceptive and sexual knowledge, attitudes, and practices; (4) environmental pressures; (5) personality factors; and (6) decision-making style. We found that the girls were generally poor contraceptors. They viewed the costs of contraception (in terms of safety) to be high; and they positively valued physical intimacy, opportunities for which come up unexpectedly and sporadically. These factors, along with their ambivalent views toward pregnancy and childbearing seemed to encourage their risk-taking behavior. Once pregnancy occurred, it was carried to term because of the strong internal and external pressures they felt to have and keep the baby. The peer-led intervention program that we are developing based on the survey findings will focus on (1) the teenagers' lack of accurate and complete knowledge about birth control and conception, (2) their limited sense of options concerning birth control and pregnancy outcomes, and (3) their poor understanding of and lack of insight into what motivates their behavior.This study is part of the investigation being conducted by the YADMAC (Young Adult and Adolescent Decision Making About Contraception) Project at Michael Reese Hospital and Medical Center, 2959 South Cottage Grove, Chicago, Illinois 60616.
