Health care insurance and advance directive completion: A population based study

Background: The relationship between advance directive (AD) completion and health insurance status is rarely studied. Method: AD completion information was collected through the 2008 Nevada Behavior Risk Factor Surveillance System (BRFSS), a statewide cross-sectional telephone survey. Nevada non-institutionalized population over 18 were randomly selected as a population sample. Respondents were divided to “health care plan group” (HCPG) and “no health care plan group” (NHCPG). Demographic and behavior risk factors were also collected. Weighted multiple logistic regressions were utilized to assess the relationships between ADs, healthcare coverage and other factors. Results: Of 4,461 respondents completing the survey, HCPG were six times more likely to have completed an AD than the NHCPG (unadjusted odds ratio: 6.08, 95% CI: 4.34-8.51). After controlling for demographic factors, the HCPG were still more than twice as likely to have completed an AD as NHCPG (AOR = 2.67, 95% CI:1.80-3.97). Only slight differences emerged for AD completion between HPCG and NHCPG when health status (AOR = 2.74, 95% CI, 1.81-4.14) and health behaviors (AOR = 2.63, 95% CI: 1.73-3.98) were added to the model. Conclusion: Health insurance, after age and college education, is the third strongest predictor of AD completion

Black microcolonial fungi as deteriogens of two famous marble statues in Florence, Italy

Blackened areas on outdoor marble statues are a significant esthetic problem due to the presence of deteriorating agents. Microcolonial black fungi, which have their natural ecological niche on rocks, play an important role in deterioration of stones used in monuments, such as marble and limestone. Black fungi were isolated from two very valuable statues exposed to the outdoor environment in Florence, Italy, the "Ratto delle Sabineâ" and the "Copia del David", and these fungi were demonstrated to be responsible for the blackening areas on the statues. The black strains showed many features common to members of rock-inhabitants dematiaceous fungi. Morphological and molecular characterization, including phylogenetic analysis, indicated that the strains isolated from both statues and in different times belong to the same species and can be assigned to the rock-inhabitant genera Sarcinomyces and Phaeococcomyces. Red yeasts growing in close proximity to the black ones, with no visible effect on the statues, were also characterized on the morphological and molecular level and identified as Sporobolomyces yunnanensis

A Bacillus subtilis cell fraction (BCF) inducing calcium carbonate precipitation: biotechnological perspectives for monumental stone reinforcement

Abstract Monumental stone decay is a consequence of the weathering action of physical, chemical and biological factors, which induce a progressive increase in porosity. To cope this degradation, bacterial calcium carbonate mineralization has been proposed as a tool for the conservation of monumental calcareous stones. The advantage of this kind of treatment is to obtain a mineral product similar to the stone substrate, mimicking the natural process responsible for stone formation. In this work, the possibility to induce CaCO3 mineralization by a bacteria-mediated system in absence of viable cells was investigated and tested on stone. Our results showed that Bacillus subtilis dead cells as wells as its bacterial cell wall fraction (BCF) can act as calcite crystallization nuclei in solution. BCF consolidating capability was further tested in laboratory on slab stones, and in situ on the Angera Church, a valuable 6th century monumental site. New crystals formation was observed inside pores and significant decrease in water absorption (up to 16.7%) in BCF treated samples. A little cohesion increase was observed in the treated area of the Angera Church, showing the potential of this application, even though further improvements are needed

The Effect of Sulfuric Acid Concentration on the Physical and Electrochemical Properties of Vanadyl Solutions

The effects of sulfuric acid concentration in VO2+ solutions were investigated via electrochemical methods and electron paramagnetic resonance. Viscosity of solutions containing 0.01 M VOSO4 in 0.1–7 M H2SO4 was measured. Diffusion coefficients were independently measured via electrochemical methods and EPR with excellent agreement between the techniques employed and literature values. Analysis of cyclic voltammograms suggest the oxidation of VO2+ to VO2+ is quasi-reversible at high H2SO4 concentrations (\u3e5 mol/L) and approaching irreversible at lower H2SO4 concentrations. Further analysis reveals a likely electrochemical/chemical (EC) mechanism where the H2SO4 facilitates the electrochemical step but hinders the chemical step. Fundamental insights of VO2+/H2SO4 solutions can lead to a more comprehensive understanding of the concentration effects in electrolyte solutions

A Robust Navigation Technique for Integration in the Guidance and Control of an Uninhabited Surface Vehicle

In this paper, we propose a novel robust navigational approach to be integrated with the guidance and control systems of an uninhabitedsurface vehicle Springer. A weighted Interval Kalman Filter (wIKF) in used for waypoint tracking, and has been compared with that of one that uses a conventional Kalman Filter (KF) navigational design. The conventional KF fails to predict correctly the vehicle’s heading when there is unmodelled uncertainty of the sensing equipment, and thus would negatively affect the performance of subsequent navigation, guidance and control (NGC). While the proposed method using a wIKF technique enhances robustness with respect to erroneous modelling, and thus secures better accuracy and efficiency in completing a mission

Responding to the crisis: are policies aimed at a strong indigenous industrial base a necessary condition for sustainable economic growth?

peer-reviewedWe examine whether a strong indigenous manufacturing base is a necessary condition for sustainable economic growth in the case of two small, open economies, Ireland and Sweden. Sweden has been impacted by the economic crisis to a lesser degree than Ireland; we explore (through a manufacturing activity lens) the reasons for the asymmetric impacts and ask if the nature of the shock is related to 'Economic Sovereignty' and to the type of industrial policy. We argue Sweden was less affected given that its indigenous firms control the highly export-focused and technology-based engineering sector whereas in Ireland high-technology sectors are controlled by foreign firms. In terms of policy implications, we suggest that industrial policy should aim for sustainable economic activity and growth such that industrial activity within the economy should be able to minimise the impact of asymmetric shocks such as the current global economic recession.ACCEPTEDpeer-reviewe

Breadwinners and Homemakers: Migration and Changing Conjugal Expectations in Rural Bangladesh

The literature on marriage norms and aspirations across societies largely sees the institution as static – a tool for the assertion of masculinities and subordination of women. The changing meanings of marriage and conjugality in the contemporary context of globalisation have received scant attention. Based on research in rural Bangladesh, this article questions the usefulness of notions of autonomy and dependence in understanding conjugal relations and expectations in a context of widespread migration for extended periods, especially to overseas destinations, where mutuality is crucial for social reproduction, though in clearly genderdemarcated domains
