Traditionally, journalism majors gain professional experience before graduation through internships, part-time or summer jobs, and campus media. Those avenues are often insufficient to adequately prepare them for the professional workplace and professional standards. This essay explores two of a journalism school's practice-based programs that…

Conceptual models are useful for facing the challenges of environmental sciences curriculum and course developers and students. These challenges are inherent to the interdisciplinary and problem-oriented character of environmental sciences curricula. In this article, we review the merits of conceptual models in facing these challenges. These…

Discusses the need for tools that analyze Earth changes in time ranges, and describes a data structure for creating and managing archives of thematic maps derived by classifying remotely sensed images by soft techniques (soft maps). Considers time-based models and provides an example of the new data structure. (Author/LRW)

Mathematical models are utilized to approximate various highly complex environmental phenomena. Model parameters exerting the most influence on model results are identified through a "sensitivity analysis." A comprehensive review is presented of more than a dozen sensitivity analysis methods. (LZ)

Human concern for the quality and protection of the natural environment forms the basis of successful environmental conservation activities. Considers environmental concern research and proposes a model that incorporates the multiple dimensions of research through which environmental concern may be evaluated. (MDH)

Discusses the objectives of conserving nature, appropriate strategies to reach those objectives, the present situation of formal conservation in South Africa, and the role of research in formulating sound conceptual models of ecosystem structure and function. (MDH)

By focusing on career development research concerning adolescents and young adults, this study illustrates the way in which Bronfenbrenner's ecological model is useful in providing a framework for career development research. (PN)

Simplicity and efficiency in design and estimation are all important in deciding on sampling strategies. A simple model is given and illustrated for four practical situations to show how a good sampling strategy should be selected. (Author)

Describes methods of designing natural resource monitoring programs to provide indications of ecosystem health, define limits of normal variation, identify abnormal conditions, and suggest potential agent of abnormal change. (MDH)

Develops a Korean environmental instruction model to encourage responsible environmental behavior. Suggests components for this model. (Author/SAH)

Disturbance-generated biomass results from endogenous and exogenous natural and cultural disturbances that affect the health and productivity of forest ecosystems. These disturbances can create large quantities of plant biomass on predictable cycles. A systems analysis model has been developed to quantify aspects of system capacities (harvest,…

Reviews literature on environmental information since 1986, with special emphasis on machine-readable sources as reported in the published literature. Highlights include a new model for studying environmental issues; environmental communication studies, including user studies; and environmental information sources, including pollution media and…

In the direction-dependent approach to location modeling developed herein, the distance within which a point of demand can find service from a facility depends on direction of measurement. The utility of the approach is illustrated through an application to groundwater remediation. (Author/MDH)

The literature on crowding in residential and laboratory settings is reviewed, and a model of crowding highlighting the importance of perceived control and group orientation is discussed. (EF)

Discusses the use of the human health risk assessment model as a basis for developing ecological risk assessment (ERA). For ERA, risk to individuals is less important than the survival of the population, with the exception of endangered species. Suggests that ERA take into account the relative reproductive value of the potentially impacted…
