Diet and habitat of northern flying squirrels ( Glaucomys sabrinus ) in the Black Hills of South Dakota

During the summers of 2005 and 2006, northern flying squirrels ( Glaucomys sabrinus Shaw) were live-captured in the northern Black Hills of South Dakota from mixed deciduous/coniferous and coniferous habitats. Squirrel captures were significantly correlated with volume of downed wood and number of snags. Diets were examined from scat collections ( n = 40, deciduous/coniferous; n = 10, coniferous). Number of fungal spores in the scat was significantly correlated with number of snags. From each scat collection, the frequencies of plant, animal, fungal, and unidentified components were determined. Hypogeous fungi were a frequent component of the diet, being found in 98.3% and 78.8% of the scat observed in 2005 and 2006. In 2006, as the frequency of dietary fungi decreased, the frequency of plant material increased from <1.0% to 8.0% and frequency of unidentified material increased from 2.0% to 74.0%. Animal content in the scat was negligible (<1.0% to 1.0%). Rhizopogon was the most frequently occurring hypogeous fungus observed. Rhizopogon spores made up 97.9% of the spores counted in 2005 and 96.4% in 2006. Elaphomyces, Gautieria, Geopora, Hymenogaster, and Hysterangium were observed at much lower frequencies. Sporocarps were collected throughout the trapping periods. Fourteen were collected in 2005 and 12 in 2006. Of the 26 sporocarps collected, 11 were Rhizopogon, 4 Elaphomyces, 2 Gautieria, 1 Hymenogaster, 7 Hysterangium, and 1 Tuber. This study is the first to examine flying squirrel diets in the Black Hills and the first to report Elaphomyces, Gautieria, Hymenogaster, Hysterangium, Rhizopogon, and Tuber sporocarps from the South Dakota Black Hills.     

Deliberative Inquiry: Integrated Ways of Working in Children Services

In striving for greater integration of children services across a number of government and non government agencies, this paper examines the effect of drawing on deliberative inquiry as the lever for realising greater alignment across agencies. The paper discusses the need for improvement in UK local government children??s services and then offers a review of the dialogue based inquiry approaches. In so doing, the paper highlights the Socratic mode of inquiry, emphasising the dual strategies of penetrative questioning, elenchus, and the process of founding new knowledge through working through confusion, aporia. This paper then reports how a London borough realised sustained change through the adoption of deliberative inquiry. The study achieved successful integration through the penetrating and contextually sensitive dialogue the inquiry participants generated, allowing them to develop the capability for realising effective organisational change. The paper concludes that deliberative inquiry facilitates individuals to speak their concerns in a manner that prompts ??consensually accepted beliefs?? to emerge through paying equal attention to the motivation of the inquiry participants, as well as to the reality of the contextual demands they need to confront.     

Application of Focus Group Interviews for Quality Management: An Action Research Project

Focus groups have the potential to provide rapid and timely collation, integration and assembly of the views of a variety of different types of stakeholders into a plausible theory. This article reflects on a tertiary education institution's utilisation of focus group interviews (FGIs) as a qualitative evaluation instrument, using action research as the methodology. Our results suggest that employing focus groups is a valuable method of gaining more insight into and adding more depth to quantitative findings during quality management. Results from focus groups enable quality assurance practitioners to provide better remedial action plans. A set of guidelines is provided for the effective conducting of focus group interviews as part of an institutional quality assurance system.     

The phylogenetic status of phyllomedusine frogs (hylidae) as evidenced from immunological studies of their serum albumins

Summary Based on immunological comparisons of the serum albumins of phyllomedusine frogs with both hyline and bufonid species, it is suggested that phyllomedusine frogs be erected to familial status within the superfamily Bufonoidea.This study was initiated in the Department of Biochemistry, University of California, Berkeley. Part of this work was supported by NSF grant No. DEB75-23543The author gratefully acknowledges the helpful advice and discussion ofA. C. Wilson. Thanks are also due toD. Wake, H. Cogger, W. Duellman andR. Heyer for generously supplying frog samples.     

Dominant and recessive deafness caused by mutations of a novel gene, TMC1, required for cochlear hair-cell function

Positional cloning of hereditary deafness genes is a direct approach to identify molecules and mechanisms underlying auditory function. Here we report a locus for dominant deafness, DFNA36, which maps to human chromosome 9q13-21 in a region overlapping the DFNB7/B11 locus for recessive deafness. We identified eight mutations in a new gene, transmembrane cochlear-expressed gene 1 (TMC1), in a DFNA36 family and eleven DFNB7/B11 families. We detected a 1.6-kb genomic deletion encompassing exon 14 of Tmc1 in the recessive deafness (dn) mouse mutant, which lacks auditory responses and has hair-cell degeneration. TMC1 and TMC2 on chromosome 20p13 are members of a gene family predicted to encode transmembrane proteins. Tmc1 mRNA is expressed in hair cells of the postnatal mouse cochlea and vestibular end organs and is required for normal function of cochlear hair cells.     

The decline of intensive intergenerational care of older people in Great Britain, 1985-1995

There are increasing concerns about the future availability of informal care for older people, particularly care by their children. This article explores past trends in the provision of informal care by children/children-in-law to their older parents/parents-in-law between 1985 and 1995 in Great Britain, using successive General Household Survey data. The article suggests that, during this period, there was a decline in co-resident intergenerational care and that this was associated with a decline in highly intensive intergenerational care. The article explores possible factors underlying these trends, in particular, demographic changes and changes in patterns of formal care for older people.

Angiotensin tachyphylaxis and vascular angiotensinase activity

Zusammenfassung Die Auffassung, dass die Gewebsangiotensinase-Aktivität entscheidend sei, ob sich eine Gewebs-Tachiphylaxie gegenüber Angiotensin entwickelt oder nicht, konnte durch Versuche an verschiedenartigen Geweben keine Bestätigung finden.
