    Notizen: Abstract This study assessed the psychometric properties of a questionnaire designed to measure consumer satisfaction with inpatient psychiatric care. To this end, 37 inpatient psychiatric units from across the United States agreed to participate. The questionnaire was completed by 1,351 individuals, or a responsible party, for an average response rate of 53%. The factor analysis identified six scales: Nonclinical Services, Psychiatric Care, Staff, Medical Outcome, Patient Education, and Program Components/Activities. The internal reliability of the scales was high to moderate (.88 to .74). Results of a stepwise regression model showed good criterion-related validity, explaining 58% of the variance in overall quality ratings. Little shrinkage in this variance occurred when the model was cross-validated. Also, differences in satisfaction levels were noted for select facility and consumer characteristics. Results are interpreted as providing support for the reliability and validity of a newly developed consumer satisfaction survey for use in evaluating inpatient psychiatric care.

    Notizen: Abstract A method is proposed whereby electrode impedance data may be analysed to yield information about the structure and composition of porous electrode materials. The method is more suitable for comparative investigations than as a technique for obtaining absolute values of the total surface area of a porous solid in contact with an electrolyte.

    Notizen: Abstract Experimental field and laboratory studies indicate that Cerithidea californica, a native mud snail, is restricted to only a portion of its normal habitat range in San Francisco Bay as a result of direct interactions with an introduced ecological equivalent, Ilyanassa obsoleta. The native snail typically inhabits marsh pans, tidal creeks and mudflats in estuaries along the Pacific coast. However, in San Francisco Bay it is confined to pans for most of the year, while the non-native snail inhabits the creeks and mudflats. Experiments and field monitoring demonstrate that this abnormal distribution pattern is caused by 1) interference competition for space in the form of an adult-adult behavioral avoidance by C. californica in the presence of invading I. obsoleta, and 2) predation by I. obsoleta on the eggs and juveniles of C. californica. The competitive exclusion of C. californica by I. obsoleta has not led to the extinction of the native snail because of the existence of a refuge for C. californica in pan habitats, beyond the physiological tolerances of I. obsoleta. As a consequence of the seasonal migrations of both species and changes in abiotic factors along the habitat gradient, repeated competitive displacements, rather than a one-time competitive exclusion, are observed between these two species. This is the first documented case of the competitive displacement of an endemic marine intertidal species by an introduced ecological equivalent.

    Notizen: Abstract To determine whether a rat heart model can provide load-insensitive measurements of cardiac function, a recently developed biventricular perfused preparation was tested. Using 29 Sprague-Dawley rat hearts perfused with modified Krebs-Henseleit buffer, ventricles functioned simultaneously with adjustable independent preload (venous reservoirs) and afterload (compliance chambers). Ultrasonic crystal pairs provided continuous left (LV) and right ventricular (RV) short-axis dimensions. LV and RV pressure-length loops (loop area = work) were generated from paired intraventricular pressure and short-axis dimensions. Load-insensitive measurements were obtained from the slopes (elastance) and x-intercepts (L0) of regression lines generated from the end-systolic coordinates of these pressure-length loops over ranges of RV and LV preloads. Measurements were made after 15 min of stable function and after 20 min of warm (37°C) ischemia. During perturbations in LV afterload, there were linear changes in dP/dt, but loop work remained relatively unchanged. RV dP/dt and work varied little with physiologic ranges of afterload. Increased RV afterload had little effect on LV function. Ischemia affected LV function more than RV function using these measurements. Elastance, however, increased after ischemia with diastolic ‘creep’ (increased L0) for both ventricles. Load-insensitive and other sophisticated hemodynamic measurements are possible with this new preparation.

    Beschreibung / Inhaltsverzeichnis: Résumé Les auteurs étudient la micro-vascularisation de la dure-mère intra-crânienne grâce à des injections de pièces anatomiques étudiées par microradiographie (73 spécimens) et à l'histologie. Il existe un réseau artériel superficiel anastomotique très riche, qui sert aussi à la vascularisation de la table interne de la voûte du crâne. Ce réseau ne s'interrompt ni au niveau des parois des sinus veineux, ni au niveau des cloisons dure-mériennes. Les artères sont le plus souvent sinueuses. Les veines peuvent être satellites des artères ou au contraire former un réseau plexulaire de fentes à l'intérieur du feuillet dural. Les parois de ces veines ne sont formées que d'un endothélium visible au sein de la couche fibreuse durale. Les artères font souvent impression sur les lumières veineuses; cette situation périlleuse explique probablement la fréquente survenue de fistules artério-veineuses au niveau de la dure-mère, connues sous le nom de fistules durales.
    Notizen: Summary The authors have studied the microvascularization of the intracranial dura mater by microradiographic and histologic examination of 73 injected anatomic specimens. There exists a very abundant superficial arterial plexus which also serves to supply the inner table of the cranial vault. This plexus is continuous, even at the walls of the venous sinuses and the dural septa. The arteries are for the most part tortuous. The veins may be satellites of the arteries or, on the contrary, from a plexiform network passing through crevices in the interior of the dural layer. The walls of these veins consist only of an endothelium to be seen within the fibrous layer of the dura. Often, the arteries compress the venous lumen; this dangerous situation probably explains the frequent occurrence of arteriovenous fistulae of the dura mater, known by the name of dural fistulae.

    Notizen: Abstract Marsh creation is currently receiving wide attention in the United States as an important tool for mitigating the impacts of development in coastal wetlands. The perception that there is no net loss in valuable coastal wetlands when development is mitigated by the creation of man-made marshes can have a substantial impact on the permitting and decision-making processes. The effective result may be the trading of natural salt marshes for man-made marshes. Techniques for marsh creation were developed by the US Army Corps of Engineers to enhance and stabilize dredge spoil materials. Most research sponsored by the Corps has been directed at determining whether these goals have been accomplished. A survey of the research indicates that there is insufficient evidence to conclude that man-made marshes function like natural salt marshes or provide the important values of natural marshes. It is necessary, therefore, for decision-makers to understand the limitations of present knowledge about man-made marshes, realistically evaluate the trade-offs involved, and relegate mitigation to its proper role in the permitting process—post facto conditions imposed on developments that clearly meet state qualifications and policies.

    Notizen: Abstract A detailed evaluation of past wetland restoration projects in San Francisco Bay was undertaken to determine their present status and degree of success. Many of the projects never reached the level of success purported and others have been plagued by serious problems. On the basis of these findings, it is debatable whether any sites in San Francisco Bay can be described as completed, active, or successful restoration projects at present. In spite of these limited accomplishments, wetland creation and restoration have been adopted in the coastal permit process as mitigation to offset environmental damage or loss of habitat. However, because the technology is still largely experimental, there is no guarantee that man-made wetlands will persist as permanent substitutes for sacrificed natural habitats. Existing permit policies should be reanalyzed to insure that they actually succeed in safeguarding diminishing wetlands resources rather than bartering them away for questionable habitat substitutes. Coastal managers must be more specific about project requirements and goals before approval is granted. Continued research on a regional basis is needed to advance marsh establishment techniques into a proven technology. In the meantime, policies encouraging or allowing quid pro quo exchanges of natural wetlands with man-made replacements should proceed with caution. The technology and management policies used at present are many steps ahead of the needed supporting documentation.
