Risk Assessment for Invasive Species

Although estimates vary, there is a broad agreement that invasive species impose major costs on the U.S. economy, as well as posing risks to nonmarket environmental goods and services and to public health. The domestic effort to manage risks associated with invasive species is coordinated by the National Invasive Species Council (NISC), which is charged with developing a science-based process to evaluate risks associated with the introduction and spread of invasive species. Various international agreements have also elevated invasive species issues onto the international policy agenda. The World Trade Organization (WTO) Sanitary and Phytosanitary (SPS) Agreement establishes rights and obligations to adhere to the discipline of scientific risk assessment to ensure that SPS measures are applied only to the extent required to protect human, animal, and plant health, and do not constitute arbitrary or unjustifiable technical barriers to trade. Currently, however, the field of risk assessment for invasive species is in its infancy. Therefore, there is a pressing need to formulate scientifically sound methods and approaches in this emerging field, while acknowledging that the demand for situation-specific empirical evidence is likely to persistently outstrip supply. To begin addressing this need, the Society for Risk Analysis Ecological Risk Assessment Specialty Group and the Ecological Society of America Theoretical Ecology Section convened a joint workshop to provide independent scientific input into the formulation of methods and processes for risk assessment of invasive species to ensure that the analytic processes used domestically and internationally will be firmly rooted in sound scientific principles.     

Outcome Expectancies and Risk Behaviors in Maltreated Adolescents

This study examined positive and negative outcome expectancies for risk behaviors, and their association with engagement in risk behaviors, in a sample of 149 maltreated adolescents. “Outcome Expectancies” are evaluative social cognitions about what will occur as a consequence of one's actions. Risk behaviors and outcome expectancies for substance use, sexual behavior, and delinquency were assessed. In all regression models, positive expectancies were significantly related to risk behaviors while negative expectancies, with one exception, were not significantly related. In three of four regression models, significant interactions were found between positive and negative expectancies in predicting risk behaviors. The nature of the interaction differed by type of risk behavior. Beyond demonstrating associations between outcome expectancies and risk behaviors in a maltreated sample, this paper contributes to the study of social information processing by demonstrating significant interactions between positive and negative expectancies.     

Maternal Welfare and Employment Experiences and Adolescent Well-Being: Do Mothers' Human Capital Characteristics Matter?

Using a representative sample of over 900 low-income urban families from the Three-City Study, analyses assessed whether maternal human capital characteristics moderate relationships between mothers' welfare and employment experiences and young adolescents' well-being. Results indicate synergistic effects whereby greater maternal education and literacy skills enhanced positive links between mothers' new or sustained employment and improvements in adolescent cognitive and psychosocial functioning. Greater human capital also enhanced the negative links between loss of maternal employment and adolescent functioning. Mothers' entrances onto welfare appeared protective for adolescents of mothers with little education but predicted decreased psychosocial functioning among teens of more educated mothers. Results suggest that maternal human capital characteristics may alter the payback of welfare and work experiences for low-income families.     

COMPLEMENTARITY AS A FUNCTION OF STAGE IN THERAPY: AN ANALYSIS OF MINUCHIN'S STRUCTURAL FAMILY THERAPY

The level of family therapist complementarity in the early, middle and late stages of therapy was explored. A micro-analysis of Salvador Minuchin with one family in successful therapy was conducted using the Structural Analysis of Social Behavior (Benjamin, 1974). Interactions from videotapes representing the three stages were coded. An ANOVA was used to compare sequences that occurred at least 5 times within any given stage. Level of therapist complementarity was significantly greater in the early and late stages than in the middle stage. Furthermore, level of therapist complementarity was significantly correlated with client change. Further research is needed to explore whether these findings can be generalized to other therapists and families.     

Life Maps: Tracking Individual Gender and Sexual Identity Construction in the Contexts of Cultures,Relationships, and Desires

The categories and language currently available to designate gender identity and sexual identity constitute over-simplifications, which do not adequately signify the complex interplays between gender and sexual orientation. It is also often difficult to recount honestly, in a way that is visible to the self and intimate others, our understandings of the complex interplays and frequent fluidity of our individual processes of gender identity development, sexual identity development, and forms of preferred erotic/sexual behavior. This essay proposes, in preliminary form, a theoretical and diagrammatic method, called a “life map,” for a context-rich illustration of an individual’s meandering journey of gender and sexual identity development. Using two illustrative lives, the essay includes cultural contexts for development as well as the gender and sexual identity locations of relationally intimate others. In addition, it suggests a framework for core types of desired erotic behaviors and provides examples of variations in such desires in relational and identity contexts.     

Rural policy into the 1990s — Self help or self deception

Self help has increasingly become a popular policy option in the search for solutions to the problems of deprivation in rural Britain, although there is little evidence to suggest that this approach has ever been the subject of vigorous analysis or evaluation.Although a number of arguments have been advanced in support of self-help policies, such justifications often owe more to popular imagery than to any objective or robust evaluation of a range of policy alternatives. Indeed, this paper suggests that many of these supporting arguments are based on false images of the structure of rural society and of the real causes of rural deprivation.Despite a growing volume of objective evidence which emphasises the limitations of self help policies, however, the paper argues that they will continue to proliferate because they have now become a powerful factor on the legitimation of the social and economic policies of central and local government in Britain. They have also become a powerful legitimising force for a growing number of rural statutory and non-statutory agencies whose existence depends to varying degrees on the political and financial support of central and local Government.
