It started with a dream: Paul's dream (Acts 16,9?10) and Aeneas as a biblical example of dreams as intercultural legitimation strategy.

Dreams are often used to promote religion, or to propagate an interpretation of religion, or to bring political ideas to the fore. A dream can be used as an indication of divine help and thus it is a perfect tool for promoting ideas. Dreams figure in religious propaganda in Christian, Jewish, and Muslim traditions (e.g., in Osama bin Laden's tapes). In classical literature, we find many kings, emperors, or generals who had visions or dreams, especially in association with their accession to power. It is the thesis of this article that in the encounter between Jewish (-Christian) cultures and the Hellenistic world dreams were shared as possible means of divine communication. An important example is the dream in Acts 16,9?10, the most Hellenistic dream of the New Testament. This dream is part of a larger unit, Paul's new move from Asia to Europe. I will try to show that the author of Acts combines here the story of Aeneas (e.g., as told by Virgil) and the story of Jesus, an interesting merging of two cultures.

The distribution of living benthic foraminifera on the continental slope and rise off southwest Norway

Surface sediment samples taken by ? corer from 45 stations on the Norwegian continental margin and in the Norway Basin have been investigated for their benthic foraminiferal content. Unlike previous studies, the living benthic foraminiferal fauna was differentiated from empty tests comprising the foraminiferal death assemblage. Factor analysis of both the living and dead faunal data reveals six living species assemblages and five corresponding dead assemblages. The additional living assemblage is characterized by the arenaceous speciesCribrostomoides subglobosum that dominates between 1400 and 2000 m water depth, but is rare in the dead faunal data.Trifarina angulosa and, to a lesser extent,Cibicides lobatulus characterize the shallowest foraminiferal assemblage from 200 to 600 m water depth, where it is associated with strong bottom currents and warm, saline Atlantic water of the North Atlantic Drift. On the slope between 600 and 1200 m water depth, theMelonis zaandami Species Assemblage dominates, particularly in areas characterized today by rapid sedimentation of terrigeneous material. Between 1000 and 1400 m depth, where the slope is covered by fine grained, organic-rich, terrigeneous mud, the living foraminiferal assemblage is characterized byCassidulina teretis andPullenia bulloides. Below 1400 m, three foraminiferal assemblages are found:C. subglobosum is found from 1400 to 2000 m,Cibicidoides wuellerstorfi andEpistominella exigua predominantly live from 2000 to 3000 m water depth, and below 3000 m,Oridorsalis umbonatus andTriloculina frigida dominate the fauna.All of theElphidium excavatum tests found in this study and theCassidulina reniforme tests found above 500 m water depth were found to be reworked.Analysis of the sediment grain-size distribution and the organic carbon content in surface samples from the deepest stations suggest that the abundance ofC. wuellerstorfi andE. exigua is positively correlated to relatively coarse (caused by planktic foraminifera) and organic-rich sediments, whereas high frequencies ofO. umbonatus andT. frigida coincide with low organic carbon content. We suggest thatC. wuellerstorfi is adapted to deep-sea environments with relatively high food supply, tolerating relatively low interstitial water oxygen content, whereasO. umbonatus may tolerate lower food supply prefering well-oxygenated interstitial waters.     

Chondrogenesis in mouse limb buds in vitro: Effects of dibutyryl cyclic AMP treatment

Abstract. We studied the effects of dibutyryl cyclic AMP (dbcAMP) on mouse limb-bud chondrogenesis at three stages of embryonic development. After 24 h of culture, limb buds with or without a covering of ectoderm were treated with 1 mM dbcAMP for 48 h and were then compared with untreated cultured limb buds. Treatment with dbcAMP enhanced cartilaginous differentiation in organ cultures of stage-17 and -19 (according to Theiler's) limb buds, although the presence of ectoderm reduced the level of dbcAMP stimulation. By stage 20, treatment with dbcAMP irreversibly inhibited cartilaginous differentiation. These results suggest that the responsiveness of mesenchymal limb-bud cells to dbcAMP is stage related. The results of histological studies as well as of analyses of DNA content and sulphated glycosaminoglycan accumulation supported the hypothesis that dbcAMP treatment induces recruitment of initially non-chondrogenic cells whose commitment explains the enhancement of cartilaginous differentiation. Limb-bud competence for chondrogenesis throughout the three developmental stages studied is also discussed.     

Staff Nurses’ Perceptions and Experiences about Structural Empowerment: A Qualitative Phenomenological Study

The aim of the study reported in this article was to investigate staff nurses’ perceptions and experiences about structural empowerment and perceptions regarding the extent to which structural empowerment supports safe quality patient care. To address the complex needs of patients, staff nurse involvement in clinical and organizational decision-making processes within interdisciplinary care settings is crucial. A qualitative study was conducted using individual semi-structured interviews of 11 staff nurses assigned to medical or surgical units in a 600-bed university hospital in Belgium. During the study period, the hospital was going through an organizational transformation process to move from a classic hierarchical and departmental organizational structure to one that was flat and interdisciplinary. Staff nurses reported experiencing structural empowerment and they were willing to be involved in decision-making processes primarily about patient care within the context of their practice unit. However, participants were not always fully aware of the challenges and the effect of empowerment on their daily practice, the quality of care and patient safety. Ongoing hospital change initiatives supported staff nurses’ involvement in decision-making processes for certain matters but for some decisions, a classic hierarchical and departmental process still remained. Nurses perceived relatively high work demands and at times viewed empowerment as presenting additional. Staff nurses recognized the opportunities structural empowerment provided within their daily practice. Nurse managers and unit climate were seen as crucial for success while lack of time and perceived work demands were viewed as barriers to empowerment.     

Predicting Effects of Water Regime Changes on Waterbirds: Insights from Staging Swans

Predicting the environmental impact of a proposed development is notoriously difficult, especially when future conditions fall outside the current range of conditions. Individual-based approaches have been developed and applied to predict the impact of environmental changes on wintering and staging coastal bird populations. How many birds make use of staging sites is mostly determined by food availability and accessibility, which in the case of many waterbirds in turn is affected by water level. Many water systems are regulated and water levels are maintained at target levels, set by management authorities. We used an individual-based modelling framework (MORPH) to analyse how different target water levels affect the number of migratory Bewick’s swans Cygnus columbianus bewickii staging at a shallow freshwater lake (Lauwersmeer, the Netherlands) in autumn. As an emerging property of the model, we found strong non-linear responses of swan usage to changes in water level, with a sudden drop in peak numbers as well as bird-days with a 0.20 m rise above the current target water level. Such strong non-linear responses are probably common and should be taken into account in environmental impact assessments.
