Policy implications of LESA factor and weight determination in Douglas County, Kansas
The Land Evaluation and Site Assessment System (LESA) developed by the United States Department of Agriculture Soil Conservation Service is designed as an aid to local planning officials to protect important agricultural lands. Preliminary LESA development for Douglas County, Kansas indicates the overall usefulness of the model for its designated purpose within Douglas County. However, model development also indicates several inherent problems with the original system, stemming predominantly from arbitrary weight recommendations and predetermined factor suppositions which do not reflect the needs of a given planning area. The effect of these recommendations and suppositions are most evident when there is a conflict of scale due to incorporation of both national and local standards through the LESA model.
Statistical evaluation of an agricultural land suitability model
The land evaluation and site assessment (LESA) method has been used extensively in the United States to assess agricultural land suitability for different localities. Despite widespread use, LESA models rarely have been evaluated in a systematic, comprehensive manner. This article discusses development of a LESA system for Hawaii, the first statewide application of the LESA methodology. The empirical model was implemented with a computerized geographic information system (GIS). The system's efficiency, ability to discriminate among land parcels, and robustness to subjective model parameter values are evaluated with statistical analyses and map overlays of GIS data. Results show great potential to simplify the original model specification, primarily through deletion of marginal site assessment factors. System output was generally insensitive to the numeric values selected for model parameters, with exception of the ratio used to combine the land evaluation (LE) and site assessment (SA) component scores. Relative supplies of the differing land attributes measured by the two components must be considered in determining an appropriate LE:SA ratio for a given area.
Preparing for group analytic psychotherapy: meeting the new patient
Preparing for group analytic psychotherapy—the patient and yourself as a therapist—is apparently done in many ways and still invested with much controversy and ambivalence. Some say, they do no selection or assessment at all. The patients or clients are taken from the waiting list in alphabetic order. Other therapists—mainly those working in National Health Services—use several assessment interviews before including patients into short- or long-term groups. Either way, this article revives some research results about assessment and hopes to inspire therapists in their first contact with the patient by presenting some examples from a clinical outpatient practice in a mental health service.
