Save the Bay

This organization is dedicated to protecting and restoring San Francisco Bay. Materials presented here cover current environmental issues affecting the bay, opportunities for citizens to become invloved in campaigns and programs, press releases and publications. Educational programs sponsored by the organization include teacher training workshops and a summer institute in which teachers can learn how to incorporate watershed education into their curricula. Students can participate in canoe trips, an Adopt-a-Site program, or in hands-on restoration of bay habitats in which they learn about the ecology of wetland habitats, the role of native plants in the ecosystem, and current issues affecting the health of the bay. Educational levels: General public, High school, Intermediate elementary, Middle school

Characterising gross plastic deformation in design by analysis

An investigation of three simple structures is conducted to identify and characterise the condition of gross plastic deformation in pressure vessel design by analysis. Limit analysis and bilinear hardening plastic analysis is performed for three simple example problems. It is found that previously proposed plastic criteria do not fully represent the effect of the hardening material model on the development of the plastic failure mechanism. A new criterion of plastic collapse based on the curvature of the load–plastic work history is therefore proposed. This is referred to as the Plastic Work Curvature or PWC criterion. It is shown that salient points of curvature correspond to critical stages in the physical evolution of the gross plastic deformation mechanism. The PWC criterion accounts for the effect of the bilinear hardening model on the development of the plastic mechanism and gives an enhanced plastic load when compared to the limit load

Save now, save later? Linkages between saving behaviour in adolescence and adulthood

The purpose of this paper is to review and critique the variety of definitions, concepts, and theories of psychological resilience. To this end, the narrative is divided into three main sections. The first considers how resilience has been defined in the psychology research literature. Despite the construct being operationalized in a variety of ways, most definitions are based around two core concepts: adversity and positive adaptation. A substantial body of evidence suggests that resilience is required in response to different adversities, ranging from ongoing daily hassles to major life events, and that positive adaptation must be conceptually appropriate to the adversity examined in terms of the domains assessed and the stringency of criteria used. The second section examines the conceptualization of resilience as either a trait or a process, and explores how it is distinct from a number of related terms. Resilience is conceptualized as the interactive influence of psychological characteristics within the context of the stress process. The final section reviews the theories of resilience and critically examines one theory in particular that is commonly cited in the resilience literature. Future theories in this area should take into account the multiple demands individuals encounter, the meta-cognitive and -emotive processes that affect the resilience-stress relationship, and the conceptual distinction between resilience and coping. The review concludes with implications for policy, practice, and research including the need to carefully manage individuals’ immediate environment, and to develop the protective and promotive factors that individuals can proactively use to build resilience
