COST OF WASH HOUSES AND COMFORT STATIONS AT RECREATION AREAS1

ABSTRACT: The cost of sanitary facilities is a major cost item in recreation areas at water resources projects. Often planners wish to analyze the tradeoffs in providing different levels of service at these areas. Cost functions are presented in this paper to enable the planner to make quick comparisons between different types of buildings, sizes, exterior treatments, and number of fixtures.     

Summary of 25 Years of Xylem Tracheids and Sewage/Sludge in the Sea

The Rapid Sewage/Sludge Indicator Technique (RSIT), developed during the early 1970's, responded to critical needs within the Bureau of Water Pollution Control. It enabled quick detection of contamination in ocean water and bottom sediments during sewage-related emergencies and routine monitoring. RSIT became an invaluable tool for resource management, in determining where and to what extent marine environments are impacted, and when immediate information is necessary for public health decisions.

The RSIT utilizes microscopic examination for terrestrial plant vascular tissue, especially the xylem tracheid elements, as identifiers of sewage/sludge. Not normally found in ocean waters, this material, in toilet paper and the roughage of the human diet which passes through the digestive system intact, is an indicator of human faecal contamination. Minimal training and common laboratory materials allow gross screening in five minutes. New studies by the United States Environmental Protection Agency (USEPA), United States Geologic Survey (USGS) and National Oceanic and Atmospheric Administration (NOAA), most recently at the 106-mile dump site off the New York Bight, revalidated the technique as a rapid, inexpensive, easy to use, semiquantitative indicator both for water column and sediment samples.     

Perceived prosocial impact,perceived situational constraints,and proactive work behavior: Looking at two distinct affective pathways

This paper examines the role of affect as a linking mechanism between experiences at work (perceived prosocial impact and situational constraints) and two distinct components of proactive work behavior (issue identification and implementation). Based on a dual‐tuning perspective, we argue that both positive affect and negative affect can be beneficial for proactive work behavior. Multi‐level path analysis using daily‐survey data from 153 employees showed that perceived prosocial impact predicted positive affect and that situational constraints as a typical hindrance stressor predicted negative affect. Negative affect, in turn, predicted issue identification, and positive affect predicted implementation. Overall, our study suggests that both positive and negative affects can be valuable in the organizational context by contributing to distinct components of proactive behavior.

Factors influencing the acceptance of nature conservation measures--a qualitative study in Switzerland

Landscapes fulfil a multitude of ecological and social functions. Due to the fact that both traditional and everyday landscapes today face many different threats, regulatory measures have been undertaken in many countries to protect and further sustainable landscape development. They include legislation as well as economic incentives. In recent years, however, it has become clear that just to have a few laws and to spend money on subsidies is not enough. Factors other than legislation are also essential to further the sustainable development of landscapes. One of the basic factors affecting the success or failure of landscape conservation measures is public acceptance of these measures. Our project took this as its starting point. The objective was to determine which conditions and factors influence acceptance positively or negatively. To this end 22 Swiss who are directly affected by nature conservation measures, in particular by mire landscape and dry meadow conservation measures, were interviewed using qualitative interview techniques. It is shown that perception, communication, and possibilities to participate are the most decisive driving factors influencing the formation of a long-lasting acceptance. Furthermore, acceptance may be based mainly on economic criteria, on usefulness, on ecological or even aesthetic aspects. It can be shown that not all of these motivations lead to a long-lasting acceptance. Ecologically based acceptance seems the most promising because it is founded on general convictions. Economic incentives--though important--seem to generate only superficial acceptance and do not seem to be as important as is usually assumed.     

The classroom setting as a source of expectations about teachers and pupils

The major purpose of this research is to examine the impact of classroom spatial arrangement (open versus traditional) and orderliness (messy versus neat) on observers' impressions of teachers and pupils. In experiments 1 and 2, samples of college students were shown color slides of vacant elementary classrooms which varied on these two physical dimensions. Subjects were asked to indicate their impressions of the teacher and the pupils who used each room by completing a set of bipolar adjective scales. Data analysis indicated that teachers in neat classrooms were rated more positively than their counterparts in disorderly classrooms on measures of kindliness, inventiveness, and organization. Pupils associated with neat classrooms were judged to be happier and better behaved. Open classroom teachers received higher ratings than traditional classroom teachers on kindliness and inventiveness. In experiment 3, the same procedure was used to obtain ratings from fifth-grade students. Their judgements of teacher and pupil characteristics were also positively affected by neatness, but classroom arrangement had no impact.
