Die Zukunft ist elektronisch
(2013)
Eine Studie der Hochschule Osnabrück zeigt: Der elektronische Pflegebericht ist in der Lage, alle für Pflegende relevanten patientenbezogenen Daten zu transportieren. Zugleich schafft er viele neue Möglichkeiten, Informationen weiterzugeben. Insgesamt lassen sich wesentlich mehr und detailliertere Informationen übermitteln als bislang über Papier.
Although national eHealth strategies have existed now for more than a decade in many countries, they have been implemented with varying success. In Germany, the eHealth strategy so far has resulted in a roll out of electronic health cards for all citizens in the statutory health insurance, but in no clinically meaningful IT-applications. The aim of this study was to test the technical and organisation feasibility, usability, and utility of an eDischarge application embedded into a laboratory Health Telematics Infrastructure (TI). The tests embraced the exchange of eDischarge summaries based on the multiprofessional HL7 eNursing Summary standard between a municipal hospital and a nursing home. All in all, 36 transmissions of electronic discharge documents took place. They demonstrated the technical-organisation feasibility and resulted in moderate usability ratings. A comparison between eDischarge and paper-based summaries hinted at higher ratings of utility and information completeness for eDischarges. Despite problems with handling the electronic health card, the proof-of-concept for the first clinically meaningful IT-application in the German Health TI could be regarded as successful.
Dieser Beitrag behandelt die Wahrnehmung von Tierschutz- und Tierrechtsorganisationen bei Fleischkonsumenten. Sowohl die Einstellung dieser Personengruppe gegenüber Tieren und Themen wie Tierschutz und Tierschutzorganisationen als auch die Wahrnehmung sowie Wirkung der Kommunikation dieser Organisationen werden thematisiert. Die Erkenntnisse stützen sich auf acht Leitfadeninterviews mit überzeugten Fleischkonsumenten, die Einblicke in die Einstellung und Verhaltensweisen von überzeugten Fleischkonsumenten bieten. Theoretische Grundlage stellen die Theorie der kognitiven Dissonanz und die Theorie der psychologischen Reaktanz dar. Vorrangig soll es darum gehen, zu erläutern, inwiefern Fleischkonsumenten eine kognitive Dissonanz beziehungsweise psychologische Reaktanz verspüren und ob daraus resultierende Effekte sichtbar werden. Besonders die Anregungen von Melanie Joy haben große Bedeutung für die vorliegenden Annahmen und Schlussfolgerungen. Die von ihr entwickelte Karnismus-Theorie spielt für der Interpretation der Ergebnisse eine wichtige Rolle (Joy, 2013).
Die Leitfadeninterviews zeigen, dass Tierschutz als wichtig empfunden wird, allerdings werden Tierschutz- und Tierrechtsorganisationen kritischer betrachtet. Auch die Kommunikationsarbeit der Organisationen stößt auf Kritik. Es können zahlreiche Hinweise darauf gefunden werden, dass Fleischkonsumenten kognitive Dissonanz und psychologische Reaktanz verspüren, die von Tierschutz- und Tierrechtsorganisationen verstärkt beziehungsweise ausgelöst werden. Es zeigt sich allerdings, dass die von vielen Organisationen eingesetzte Kommunikationsstrategie hinterfragt werden sollte. Denn der Einsatz emotionaler Appelle in Form von Schockbildern oder Ähnlichem erweist sich zumeist als wenig sinnvoll. Die Ergebnisse können Anregungen für eine optimierte Kommunikationsarbeit von Tierschutz- und Tierrechtsorganisationen bieten.
Der N. mandibularis und seine Äste müssen sich bei Bewegungen des Kiefers und der HWS an die veränderten umliegenden Strukturen anpassen, um die Funktionsfähigkeit zu erhalten. Ziel dieser Querschnittstudie war herauszufinden, ob sich die Neurodynamik des N. auriculotemporalis mithilfe von Sonografie untersuchen lässt. Dazu wurde bei 21 Probanden der N. auriculotemporalis im Querschnitt (transversal) und in longitudinaler Ansicht während verschiedener kombinierter Kiefer- und zervikaler Bewegungen aufgezeichnet und beurteilt.
Die transversale Untersuchung ergab die signifikant größten Bewegungen bei hochzervikaler Flexion der HWS und gleichzeitiger Laterotrusion der Mandibula zur Gegenseite. Die longitudinale Untersuchung zeigte eine vermehrte Bewegung des Nervs bei Einstellung der HWS in hochzervikaler Flexion im Vergleich zur habituellen Position bei Depression und Laterotrusion der Mandibula zur Gegenseite (nicht signifikant). Eine Korrelation zwischen den Resultaten der transversalen longitudinalen Messung war nicht nachweisbar. Die Ergebnisse lassen annehmen, dass vor allem hochzervikale Flexion, Laterotrusion und Depression einen Einfluss auf die Dynamik des N. auriculotemporalis haben.
Standard extensive green roofs (EGRs) with their shallow substrate layers represent extreme sites for plant growth and therefore are planted mostly with drought-resistant species, including non-native plant species. As standard EGR substrates often lack potentially mutualistic soil microorganisms, it has been stated that inoculation with arbuscular mycorrhizal fungi (AMF) might increase plant performance and drought resistance. Aiming to support native biodiversity on EGRs, we tested whether AMF inoculation into standard green roof substrate can enhance plant performance and drought resistance of regionally occurring native dry grassland species.
The results of a pot experiment with 11 native plant species growing with and without AMF inoculation showed considerable differences in fitness-relevant plant traits. Over 88 days of moderate drought conditions, inoculated plants produced 2.5 times more above-ground biomass than control plants. In addition, the number of inflorescences on inoculated plants was significantly higher in 5 out of 7 flowering species. Under severe drought stress created by stopping the water supply, however, inoculated plants wilted on average 2.38 days earlier than control plants.
Although the underlying mechanisms of the observed results remain unresolved, AMF inoculation might help to enhance an earlier and higher seed set, facilitating the establishment of a soil seed bank, which is necessary for a self-sustaining plant population in drought-governed habitats such as EGRs.
Ecological restoration of an urban demolition site through introduction of native forb species
(2020)
Urban brownfields can provide habitats for endangered native plant species but may also support invasive non native species. The aim of our study was to develop and test different measures for the ecological restoration of an urban brownfield. We aimed to enhance native plant species richness by seeding two native forb seed mix tures containing 25 (HD-mixture) and 13 species (LD-mixture), respectively, without affecting spontaneously colonizing plant species of nature conservation value. Additionally, we tested the effects of species introduction and mowing on the establishment of invasive non-native plant species, woody species development, and per ennial grass dominance.
With establishment rates of 84% (HD) and 92% (LD) in the first study year and about 60% for both seed mixtures in the fourth year, species introduction was successful and led to rapid re-vegetation of the formerly bare brownfield. Although seeding did not result in increased species richness using either seed mixture, the dominance of perennial grasses was significantly reduced by the establishment of forb species from the HD mixture. Overall, we observed the spontaneous establishment of ten plant species of conservation value; seeding affected these species only temporarily, in the second year. Seeding (with either seed mixture) and mowing both resulted in reduced cover of woody species and a lower frequency of the invasive non-native Robinia pseudoa cacia.
Our study demonstrated the high nature conservation value of dry and nutrient-poor urban brownfields for spontaneously occurring threatened plant species. Further studies have to evaluate if the reduced cover of grasses and woody species through introduction of site-specific native forb species might increase these sites’ aesthetic value and broader acceptance of brownfields by urban residents.
Extensive green roofs (EGRs) offer several beneficial ecosystem services for sustainable urban development. However, most standard green roofs have been designed with species-poor plant mixtures containing non-native species. Aiming to increase the nature conservation values of EGRs, we developed and tested a vascular plant seed mixture including regionally occurring native sandy dry grassland species in experimental miniature roofs in Northwestern Germany (temperate oceanic climate) over 4 years. We tested the mixture at two seed densities (1 and 2 g/m2). Additionally, we tested seeding at 1 g/m2 and introducing raked plant material collected from an ancient dry grassland. The total establishment rates of sown species reached 92–96% in the first year, but dropped to 40–60% in the last 2 years, with the highest values for the plots with raked material. Twenty-four additional species (11 vascular, 7 lichen, and 6 moss species, including 7 red-list species) typical of sandy dry grasslands were introduced through the raked material. Vascular plants reached 60–70% cover in the second year. Severe drought periods in the third and the fourth year led to a strong decline of vascular plant cover then. As this cover was higher in the plots with raked material, we assume facilitative effects through the well-developed cryptogam layer containing a mix of pleurocarpous and acrocarpous mosses and lichens. Spontaneously establishing acrocarpous mosses in sown plots did not seem to provide this same function. We conclude that EGRs designed with regionally occurring sandy dry grassland plant species and especially the application of raked plant material from ancient grassland is a fruitful approach to increase the value of green roofs for native phytodiversity.
Green roofs are known to mitigate the negative effects of urban consolidation by offering diverse ecosystem functions compared to non-vegetated roofs. However, the support for native biodiversity might be improved by using native plant species. In a mesocosm experiment, we studied the suitability of three commercial green-roof growth substrates for the establishment of 27 native plant species from dry sandy grasslands of northwestern Germany over the course of four years. The substrates were mineral-based, but differed in the layering of organic matter. Total establishment rates reached 44–59% in Year 4, indicating the general suitability of the substrates. During the first weeks after seeding, with light irrigation, the vascular plant cover was greater in the similar substrates Zincolit® Plus (Z) and Zincolit® Plus-Leicht (ZL) with their compost-based organic mulch layers than in the substrate Sedumteppich (ST) with its organic matter evenly admixed with the mineral aggregates. In Years 2 and 3, however, the vascular plant cover was greater in the ST substrate, likely due to the better availability of water and nutrients from the organic matter compared to the dry surface-mulch layer variants Z and ZL. After severe drought events, the decline in plant cover was more pronounced in the ST substrate, likely representing a trade-off between lush growth and a susceptibility to drought. An indicator-species analysis revealed differences in species composition between the ST and Z/ZL substrates. Annual plant species were indicators of the ST substrate. Perennials, such as Thymus pulegioides and Achillea millefolium, were typical of the Z and ZL substrates. In addition to the general suitability of the tested standard substrates for target species establishment, the study indicated that a combination of different layers of substrate components resulted in different vegetation patterns that may have a positive effect on green-roof biodiversity.
