Friendships are an integral part of the human experience. Yet, dementia often takes a toll on social relationships, and many friends withdraw. This research, however, focuses on friendships that remain, despite a diagnosis of dementia. It examines the quality of the friendships of people with dementia and long-term friendships. Data were collected through focus group interviews with people with early stage dementia and their care partners, and through interviews with designated friends. The findings show that people with dementia do have friends that remain and they have a wide variety of friendships, from those based on one shared activity to those of multifaceted deep relationships. The long-term friendships, which last across the various stages of dementia, appear to fall into two types: one, where the person with dementia has become more like a family member than a friend (suffusion); and the other where the diagnosis of dementia was the impetus for the relationship to become closer (progressive friendship).

Energy Policy | Year: 2010

This article documents that the hydrogen economy continues to attract significant attention among politicians, the media, and some academics. We believe that an explanation lies in the way that the hydrogen economy fulfills psychological and cultural needs related to a future world where energy is abundant, cheap, and pollution-free, a "fantasy" that manifests itself with the idea that society can continue to operate without limits imposed by population growth and the destruction of the environment. The article begins by explaining its research methodology consisting of two literature reviews, research interviews of energy experts, and the application of symbolic convergence theory, a general communications theory about the construction of rhetorical fantasies. We then identify a host of socio-technical challenges to explain why the creation of a hydrogen economy would present immense (and possibly intractable) obstacles, an argument supplemented by our research interviews. Next, we employ symbolic convergence theory to identify five prevalent fantasy themes and rhetorical visions-independence, patriotism, progress, democratization, and inevitability-in academic and public discussions in favor of the hydrogen economy. We conclude by offering implications for scholarship relating to energy policy more broadly. © 2009 Elsevier Ltd. All rights reserved.

Aim: Although patterns are emerging for macroorganisms, we have limited understanding of the factors determining soil microbial community composition and productivity at large spatial extents. The overall objective of this study was to discern the drivers of microbial community composition at the extent of biogeographical provinces and regions. We hypothesized that factors associated with land use and climate would drive soil microbial community composition and biomass. Location: Great Basin Province, Desert Province and California Floristic Province, California, USA. Methods: Using phospholipid fatty acid analysis, we compared microbial communities across eight land-use types sampled throughout the State of California, USA (n= 1117). Results: The main factor driving composition and microbial biomass was land-use type, especially as related to water availability and disturbance. Dry soils were more enriched in Gram-negative bacteria and fungi, and wetter soils were more enriched in Gram-positive, anaerobic and sulphate-reducing bacteria. Microbial biomass was lowest in ecosystems with the wettest and driest soils. Disturbed soils had less fungal and more Gram-positive bacterial biomass than wildland soils. However, some factors known to influence microbial communities, such as soil pH and specific plant taxa, were not important here. Main conclusions: Distinct microbial communities were associated with land-use types and disturbance at the regional extent. Overall, soil water availability was an important determinant of soil microbial community composition. However, because of the inclusion of managed and irrigated agricultural ecosystems, the effect of precipitation was not significant. Effects of environmental and management factors, such as flooding, tillage and irrigation, suggest that agricultural management can have larger effects on soil microbial communities than elevation and precipitation gradients. © 2009 Blackwell Publishing Ltd.

Significant research effort has recently gone into the synthesis of thermoelectric nanomaterials through different chemical approaches since nanomaterials chemistry became a promising strategy for improving thermoelectric performance. Different thermoelectric nanocrystals, especially PbTe, Bi 2Te3 and CoSb3, with various compositions and morphologies have been successfully prepared by solvo/hydrothermal, electrochemical, and ligand-based synthesis methods. Such nanoscale materials show not only substantial reduction in thermal conductivity due to increased phonon scattering at nanoscale grain boundaries and lower densities of phonon states but possibly also an enhancement in thermopower due to electronic quantum size effects. More recently, the notoriously low power factors of thermoelectric nanomaterials prepared by wet chemistry have been significantly improved by using an increasingly cross-disciplinary approach towards the bottom-up synthesis that combines expertise from chemistry, physics, and materials engineering. In this review, we discuss the recent progress and current challenges of preparing thermoelectric nanomaterials with solution-based chemistry approaches. © 2011 The Royal Society of Chemistry.

This paper presents an assessment designed to measure computational thinking skills of fourth grade students. The students in two public schools were given a set of Scratch programming challenges. The SOLO taxonomy was used to classify student programming responses based on the degree of understanding of the problem structure. The majority of fourth grade students from one school demonstrated the ability to synchronize the costume and motion of a single character sprite, as well as synchronize a basic conversation between multiple sprites. However, they struggled to integrate motion and costume changes into a multi-sprite conversation. The majority of fourth grade students from the second school, where reading and math comprehension scores fall below the state minimum requirements for proficiency, were unable to demonstrate a basic understanding of the programming tasks. The results suggest that fourth grade students who read at grade level are capable of understanding the relationships between multiple concerns within a single script, along with synchronizing a single concern across multiple scripts, but are challenged when synchronizing multiple concerns across multiple scripts.
