Spectroscopic studies of synthetic and natural beidellites: A review

This paper represents an overview of the spectroscopic studies of both synthetic and naturally occurring beidellites performed as part of my research over the past 16 years. It shows that detailed information on the local structure of beidellite and changes in this local structure upon heating can be obtained by combining a range of spectroscopic techniques such as mid-infrared, near-infrared, infrared emission, Raman, nuclear magnetic resonance and X-ray photoelectron spectroscopy.

The Influence of Geology and Season on Macroinvertebrates in Belizean Streams: Implications for Tropical Bioassessment

Considerable attention has been paid to the potentially confounding effects of geological and seasonal variation on outputs from bioassessments in temperate streams, but our understanding about these influences is limited for many tropical systems. We explored variation in macroinvertebrate assemblage composition and the environmental characteristics of 3rd- to 5th-order streams in a geologically heterogeneous tropical landscape in the wet and dry seasons. Study streams drained catchments with land cover ranging from predominantly forested to agricultural land, but data indicated that distinct water-chemistry and substratum conditions associated with predominantly calcareous and silicate geologies were key determinants of macroinvertebrate assemblage composition. Most notably, calcareous streams were characterized by a relatively abundant noninsect fauna, particularly a pachychilid gastropod snail. The association between geological variation and assemblage composition was apparent during both seasons, but significant temporal variation in compositional characteristics was detected only in calcareous streams, possibly because of limited statistical power to detect change at silicate sites, or the limited extent of our temporal data. We discuss the implications of our findings for tropical bioassessment programs. Our key findings suggest that geology can be an important determinant of macroinvertebrate assemblages in tropical streams and that geological heterogeneity may influence the scale of temporal response in characteristic macroinvertebrate assemblages.

Successful aging at 100 years: the relevance of subjectivity and psychological resources

Very old individuals seem to present an admirable capacity to overcome adversities and adapt to the challenges of advanced age. However, studies focusing successful pattern of centenarians found that they may easily fail to be categorized as successful agers when objective criteria are applied. The present study examines if centenarians can be considered successful agers. Following Rowe and Kahn's successful aging model, the primary goal was to clarify whether centenarians are able to be successful agers according to objective and subjective criteria of no major disease and disability, high cognitive and physical functioning and engagement with life. The second goal was to investigate whether socio-demographic factors, psychological, social, and economic resources are related to objective and subjective successful aging profiles.

Ensuring Quality Services for Infants and Toddlers with Disabilities and their Families within the BabyNet Early Intervention System: An Analysis of Current and Needed Resources

This report prioritizes the targeted, additional resources First Steps and system stakeholders believe will be necessary to ensure the BabyNet system earns a federal designation of “meets requirements” for the first time in its 25 year history. It lists key recommendations to help meet those requirements.
