Psychiatric services in general hospitals: a report of the Northern California Psychiatric Society's committee on the need for psychiatric services in general hospitals

A study made by a special committee appointed for the purpose by the Northern California Psychiatric Society found that a real need exists for local psychiatric services in general hospitals of the Northern California area. Such services can be provided readily-and in some communities are already available. A broad segment of the population looks to the general hospital to provide diagnosis and care and so enable the patient's prompt recovery from psychiatric disorders. The study further emphasizes the importance of such factors as a competent psychiatric chief, adequate staff and personnel and good planning in organizing inpatient and outpatient facilities and integrating treatment so that all the functions of the hospital are available to psychiatric patients. Granted these special considerations, the services can be provided more easily than many physicians, including some psychiatrists and administrators, suppose.     

Interactive effects of water table and precipitation on net CO2 assimilation of three co-occurring Sphagnum mosses differing in distribution above the water table

Sphagnum cuspidatum , S. magellanicum and S. rubellum are three co-occurring peat mosses, which naturally have a different distribution along the microtopographical gradient of the surface of peatlands. We set out an experiment to assess the interactive effects of water table (low: −10 cm and high: −1 cm) and precipitation (present or absent) on the CO₂ assimilation and evaporation of these species over a 23-day period. Additionally, we measured which sections of the moss layer were responsible for light absorption and bulk carbon uptake. Thereafter, we investigated how water content affected carbon uptake by the mosses. Our results show that at high water table, CO₂ assimilation of all species gradually increased over time, irrespective of the precipitation. At low water table, net CO₂ assimilation of all species declined over time, with the earliest onset and highest rate of decline for S. cuspidatum . Precipitation compensated for reduced water tables and positively affected the carbon uptake of all species. Almost all light absorption occurred in the first centimeter of the Sphagnum vegetation and so did net CO₂ assimilation. CO₂ assimilation rate showed species-specific relationships with capitulum water content, with narrow but contrasting optima for S. cuspidatum and S. rubellum . Assimilation by S. magellanicum was constant at a relatively low rate over a broad range of capitulum water contents. Our study indicates that prolonged drought may alter the competitive balance between species, favoring hummock species over hollow species. Moreover, this study shows that precipitation is at least equally important as water table drawdown and should be taken into account in predictions about the fate of peatlands with respect to climate change.
