Can Producers Place Valid and Reliable Valuations on Wool Price-Risk Information?

Using the contingent valuation method farmers in the high rainfall region of Western Australia were asked to value the information that they used to reduce risk associated with wool prices. To ascertain whether these values were both valid and reliable they were combined with additional data collected from the questionnaires and incorporated into profit functions so that farmers' attitudes towards risk could be estimated. These risk attitudes may be deemed reliable and valid providing they correspond to those estimated by other researchers. Results showed that the farmers' risk aversion coefficients were comparable to those estimated in the Australian literature. Therefore it may be argued that these farmers were able to nominate valid and reliable valuations for the information that they used.
Hand contamination during routine care in medical wards: the role of hand hygiene compliance.

The hands of healthcare workers (HCWs) are the most common vehicle for the transmission of micro-organisms from patient to patient and within the healthcare environment. The aim of this study was to evaluate the impact of a multimodal campaign on the type and amount of resident and transient flora and the presence of potential risk factors for hand contamination during routine care. A before-after (PRE and POST periods) interventional study was carried out in medical wards of a tertiary care hospital. Eighty-nine samples were analysed. Samples were cultured immediately before patient contact using a glove-juice method. Data collected included socio-demographic and risk factors for hand contamination. Flora was measured as log10 c.f. u. ml(-1) and evaluated by comparing median values in the PRE and POST periods. Transient flora was isolated from the hands of 67.4 and 46.1 % of HCWs in the PRE and POST periods, respectively (P<0.001). Enterobacteriaceae, Pseudomonas spp. and meticillin-sensitive Staphylococcus aureus were the predominant contaminants. Resident flora was isolated from 92.1 % of HCWs in the PRE period and from 70.8 % in the POST period (P<0.001). The meticillin-resistant coagulase-negative staphylococci log10 c.f. u. count ml(-1) decreased from 1.96 ± 1.2 to 0.89 ± 1.2 (mean ± s d; P<0.001), and the global flora count decreased from 2.77 ± 1.1 to 1.56 ± 1.4 (P<0.001). In the POST period, the wearing of fewer rings (P<0.001), shorter fingernail length (P = 0.008), a shorter time since recent hand hygiene (HH) (P = 0.007) and an increased use of alcohol-based hand rub instead of soap (P<0.001) were documented. The HH multimodal strategy reduced the number of risk factors and the level of HCW hand contamination.
Enhancing Participation in Disadvantaged Urban Neighbourhoods

Abstract Participation in neighbourhoods is a highly valued phenomenon. Participation is the basis of a shared social life, but it also makes everyday life, and the lived experience of people participating in it, political. From a public administration perspective, governance and formal policy-making are increasingly reaching out to citizens, instead of drawing solely on representative mechanisms of local government. This paper investigates how practitioners working in disadvantaged neighbourhoods in Dutch cities enhance participation. Using empirical data from research in disadvantaged neighbourhoods in The Netherlands, the paper shows that these practitioners either start projects that connect people in their own life world or connect policy-makers and policy to initiatives on the ground. As a result, they create the opportunity for many to develop their citizenship and become a more active participant in their local communities.
Interaction of Investor Trades and Market Volatility: Evidence from the Tokyo Stock Exchange

This paper examines the relation between market volatility and investor trades by identifying who supplies and demands market liquidity on the Tokyo Stock Exchange. Because the different trading patterns of various investor types such as individual investors, institutional investors, and foreign investors affect market liquidity differently, we find that market volatility fluctuates significantly depending on which investor types participate in trade. We show that market volatility increases by more than 50% from the average level when there are greater buy trades by momentum investors that demand liquidity and there are less sell trades by contrarian (or profit-taking) investors that supply liquidity. On the other hand, volatility dampens by more than 57% when there are greater sell trades by profit-taking investors, mostly by domestic investors, while there are less momentum buy trades.
Catheter-Based Renal Sympathetic Denervation for Resistant Hypertension: Durability of Blood Pressure Reduction Out to 24 Months

Renal sympathetic hyperactivity is seminal in the maintenance and progression of hypertension. Catheter-based renal sympathetic denervation has been shown to significantly reduce blood pressure (BP) in patients with hypertension. Durability of effect beyond 1 year using this novel technique has never been reported. A cohort of 45 patients with resistant hypertension (systolic BP ≥160 mm Hg on ≥3 antihypertension drugs, including a diuretic) has been originally published. Herein, we report longer-term follow-up data on these and a larger group of similar patients subsequently treated with catheter-based renal denervation in a nonrandomized manner. We treated 153 patients with catheter-based renal sympathetic denervation at 19 centers in Australia, Europe, and the United States. Mean age was 57±11 years, 39% were women, 31% were diabetic, and 22% had coronary artery disease. Baseline values included mean office BP of 176/98±17/15 mm Hg, mean of 5 antihypertension medications, and an estimated glomerular filtration rate of 83±20 mL/min per 1.73 m2. The median time from first to last radiofrequency energy ablation was 38 minutes. The procedure was without complication in 97% of patients (149 of 153). The 4 acute procedural complications included 3 groin pseudoaneurysms and 1 renal artery dissection, all managed without further sequelae. Postprocedure office BPs were reduced by 20/10, 24/11, 25/11, 23/11, 26/14, and 32/14 mm Hg at 1, 3, 6, 12, 18, and 24 months, respectively. In conclusion, in patients with resistant hypertension, catheter-based renal sympathetic denervation results in a substantial reduction in BP sustained out to ≥2 years of follow-up, without significant adverse events.
Affine Models, Credit Spreads and the Delivery Option of a Multi-Issuer Bond Future

The contribution of this paper is two-fold: Firstly we use the intensity-based framework of Duffie/Singleton (1999) to analyse empirically the credit spread between Italian and German government bonds in an affine model framework. Secondly we value the delivery option of a multi-issuer bond-future contract. This contract allows the short to deliver bonds of different issuers and, therefore, depends on the credit spread between these bonds. The empirical part studies the valuation of German and Italian bonds using two-factor affine models. Similar to Pearson/Sun (1994) we combine cross-sectional and time-series information to estimate the process parameters with maximum likelihood. From our results we conclude that two-factor models produce about the same pricing errors for German and Italian bonds. However, both models explain only imperfectly the observed convex shape and the "volatility smile" of the default-spread structure. In the second part we analyse the delivery option of a bond future that is similar to the German Bund Future but allows additionally to deliver Italian government bonds. In contrast to our results for the valuation of coupon bonds we find that the option values in both models differ considerably. Our results provide useful insights for empirical work concerning affine intensity based models for the valuation of default-risky bonds and options that depend on a credit spread.
Risk moderates the outcome of relationship education: a randomized controlled trial.

OBJECTIVE To test whether the effects of relationship education programs generalize across couples regardless of their baseline levels of risk for relationship distress, or whether intervention effects vary systematically as a function of risk. The former result would support primary prevention models; the latter result would support a shift toward secondary prevention strategies. METHOD Engaged and newlywed couples (N = 130) were randomized into 1 of 3 relationship education programs. Individual and relational risk factors assessed at baseline were tested as moderators of 3-year changes in relationship satisfaction, overall and in each of the 3 treatment conditions. RESULTS Treatment effects varied as a function of risk, and more so with variables capturing relational risk factors than individual risk factors. High-risk couples (e.g., couples with lower levels of baseline commitment and satisfaction) tended to decline less rapidly in satisfaction than low-risk couples following treatment. Couples with acute concerns at baseline, including higher levels of physical aggression and alcohol use, benefitted less from intervention than couples without these concerns. Comparisons across treatment conditions indicate that couples with relatively high baseline satisfaction and commitment scores declined faster in satisfaction when assigned to an intensive skill-based intervention, as compared with a low-intensity intervention. CONCLUSIONS Outcomes of skill-based relationship education differ depending on premarital risk factors. Efficient identification of couples at risk for adverse relationship outcomes is needed to refine future prevention efforts, and deploying prevention resources specifically to at-risk populations may be the most effective strategy for strengthening couples and families.
Recent progress in the understanding and treatment of nonepileptic seizures

Purpose of review There has been a steady increase in the number of publications about (psychogenic) nonepileptic seizures (NES) over the past two decades. This review focuses on work published in the past 3 years. It summarizes the most important developments in terms of diagnosis, cause, clinical manifestations and treatment of NES. Recent findings Several recent studies demonstrate the scope and limitation of questionnaire-based and conversation analytic approaches to the differential diagnosis of epilepsy and NES. Experimental work has revealed that patients with NES have increased levels of physiological arousal at rest which are associated with abnormal mental processing. There is a growing understanding of the meaning and clinical significance of the heterogeneous manifestations of NES. Several studies document the therapeutic potential of an early and effective communication of the diagnosis of NES. A number of randomized controlled or uncontrolled long-term follow-up pilot studies suggest that different forms of psychotherapy are effective for NES. Summary Recent research has improved our understanding of NES as a biopsychosocial disorder. Clear diagnostic and management pathways for patients with NES are likely to emerge in the near future.
Ecological Factors Influencing Aedes aegypti (Diptera: Culicidae) Productivity in Artificial Containers in Salinas, Puerto Rico

Abstract We investigated the effects of environmental factors and immature density on the productivity of Aedes aegypti (L.) and explored the hypothesis that immature populations were under nutritional stress. In total, 1,367 containers with water in 624 premises were studied in Salinas, southern Puerto Rico (May–July 2004). We counted 3,632 pupae, and most female pupae (70%) were in five of 18 types of containers. These containers were unattended and influenced by local yards’ environmental conditions. Pupal productivity was significantly associated with the number of trees per premise, water volume, and lower water temperatures. Larval and pupal abundance were larger in containers with leaf litter or algae. Pupal productivity and biomass of emerging females varied in containers with litter of different tree species. We found a significant and positive association between numbers of larvae and pupae of Ae. aegypti and a negative relationship between larval density and mass of emerging females. From multivariate analyses, we interpreted that 1) food limitation or competition existed in a number of containers; and 2) to a lesser extent, there was lack of negative larval density effects in containers with a larger water volume and lower temperature, where emerging females were not under nutritional stress. Corroborating evidence for food limitation or intraspecific competition effects came from our observations that females emerging in the field had an average body mass comparable with those females produced in the laboratory with the lowest feeding regime. Ae. aegypti larvae in Salinas are most likely influenced by resource limitation or competition and by rainfall in unmanaged containers in the absence of aquatic predators. Source reduction and improved yard management targeting unattended containers would eliminate most Ae. aegypti productivity and removal or control of shaded, larger containers would eliminate the production of the largest emerging mosquito females in the study area.
Association between general self-efficacy level and use of dietary supplements in the group of American football players.

BACKGROUND Increased nutritional demands of athletes should be covered with a variable well-balanced diet, supported by dietary supplements stimulating synthesis of energy, development of muscle mass and strength, and improving physical capacity. OBJECTIVE The aim of this study was to analyze an association between the level of general self-efficacy and dietary supplement use among Polish athletes practicing American football on a competitive basis. MATERIAL AND METHODS The study included the group of 100 athletes (20-30 years of age, mean 24.27±2.76 years) who practiced American football on a competitive basis. The popularity of various dietary supplements was determined with an original survey, and the level of general self-efficacy with General Self-Efficacy Scale (GSES) by Schwarzer et al. Statistical analysis, conducted with Statistica 10.0 PL software, included intergroup comparisons with the Chi-square test. RESULTS Isotonic drinks (74%), vitamin (65%) and mineral supplements (50%) and protein concentrates (53%) turned out to be the most popular ergogenic supplements among the American footballers. The group of less popular supplements included caffeine and/or guarana (44%), joint supporting supplements (40%), BCAA amino acids (39%), creatine (36%), carbohydrate concentrates (30%) and omega-3 fatty acids (30%). Analysis of a relationship between the popularity of ergogenic supplements and general self-efficacy showed that the athletes presenting with lower levels of this trait used multivitamin supplements significantly more often than did the persons characterized by lower self-efficacy levels (p<0.05). CONCLUSIONS The popularity of some dietary supplements varied depending on the general self-efficacy level of the athletes; the popularity of vitamins was significantly higher among the sportsmen who presented with lower levels of this trait.
Neutralizing Antibody Responses to Human Herpesviruses 6 and 7 Do Not Cross-React with Each Other, and Maternal Neutralizing Antibodies Contribute to Sequential Infection with These Viruses in Childhood

ABSTRACT Seroprevalence of human herpesvirus 6 (HHV-6) and HHV-7 infections is very high throughout the world, and almost all people are exposed first to HHV-6 and second to HHV-7 in their childhood. However, it is not clear whether the neutralizing (NT) antibody response between each virus is cross-reactive or not. To elucidate the NT antibody response between each virus, 55 serum samples from an adult group (subjects 22 to 88 years old) and 60 serum samples from a young group (subjects 2 to 18 years old) were examined by a dot blot method for detecting viral late antigen. Thirty-nine serum samples obtained from cord bloods and a few serum samples obtained from pediatric patients with exanthem subitum were also examined to assess the maternal transferred NT antibodies against each virus. The NT antibody titers against HHV-7 in the adult group remained high throughout all the individuals, and none were negative. Those against HHV-6 were high values in the young group but low values, including negative values (three samples), in the adult group. These results suggested that the NT antibody response to either HHV-6 or HHV-7 in each individual was specific to each virus and did not cross-react with each other. In the adult group, the NT antibody response to HHV-6 decreased, while that to HHV-7 remained high throughout all the individuals. Maternal transferred NT antibody titers against HHV-7 were higher and remained longer after birth than those of HHV-6, and these findings were in accord with the clinical observation that HHV-6 infection usually occurs earlier than HHV-7 infection.
Design of an automatic testing for FPGAs

This paper presents a new design for testing SRAM-based field programmable gate arrays (FPGAs). The original SRAM part is modified a bit so that the FPGA gets the ability to automatically shift the data on-chip and then the test becomes faster. This method does not need a large outside memory (off-chip memory) for saving the test data. It is proved that this method detects multiple faults and covers 100%; of modeled faults. The simulation results of Xilinix XC4000 family, using CAD tools, shows that the routing and the placement of this method are easily achieved.
Decline in mortality from coronary heart disease in Poland after socioeconomic transformation: modelling study

Objectives To examine how much of the observed rapid decrease in mortality from coronary heart disease in Poland after the political, social, and economic transformation in the early 1990s could be explained by the use of medical and surgical treatments and how much by changes in cardiovascular risk factors. Design A modelling study. Setting Sources of data included controlled trials and meta-analyses, national surveys, and official statistics. Participants Population of adults aged 25-74 in Poland in 1991-2005. Main outcome measures Number of deaths prevented or postponed in 2005 attributable to specific treatments for coronary heart disease and changes in risk factors. A previously validated epidemiological model for coronary heart disease was used to combine and analyse data on the uptake and effectiveness of specific cardiac treatments and changes in risk factors. The observed fall in deaths from coronary heart disease from 1991 to 2005 was then partitioned among specific treatments and risk factor changes. Results From 1991 to 2005, the death rate from coronary heart disease in Poland halved, resulting in 26 200 fewer coronary deaths in 2005 in people aged 25-74. About 37% (minimum estimate 13%, maximum estimate 77%) of this decrease was attributable to treatments, including treatments for heart failure (12%), initial treatments for acute coronary syndrome (9%), secondary prevention treatments after myocardial infarction or revascularisation (7%), chronic angina treatments (3%), and other treatments (6%). About 54% of the fall was attributed to changes in risk factors (minimum estimate 41%, maximum estimate 65%), mainly reductions in total cholesterol concentration (39%) and an increase in leisuretime physical activity (10%); however, these were partially offset by increases in body mass index (−4%) and prevalence of diabetes (−2%). Blood pressure fell in women, explaining about 29% of their decrease in mortality, but rose in men generating a negative influence (−8%). About 15% of the observed decrease in mortality was attributable to reduced smoking in men but was negligible in women. Conclusions Over half of the recent fall in mortality from coronary heart disease in Poland can be attributed to reductions in major risk factors and about one third to evidence based medical treatments.
Characterization and Evolution of Anthranilate 1,2-Dioxygenase from Acinetobacter sp. Strain ADP1

ABSTRACT The two-component anthranilate 1,2-dioxygenase of the bacteriumAcinetobacter sp. strain ADP1 was expressed inEscherichia coli and purified to homogeneity. This enzyme converts anthranilate (2-aminobenzoate) to catechol with insertion of both atoms of O2 and consumption of one NADH. The terminal oxygenase component formed an α3β3 hexamer of 54- and 19-kDa subunits. Biochemical analyses demonstrated one Rieske-type [2Fe-2S] center and one mononuclear nonheme iron center in each large oxygenase subunit. The reductase component, which transfers electrons from NADH to the oxygenase component, was found to contain approximately one flavin adenine dinucleotide and one ferredoxin-type [2Fe-2S] center per 39-kDa monomer. Activities of the combined components were measured as rates and quantities of NADH oxidation, substrate disappearance, product appearance, and O2 consumption. Anthranilate conversion to catechol was stoichiometrically coupled to NADH oxidation and O2consumption. The substrate analog benzoate was converted to a nonaromatic benzoate 1,2-diol with similarly tight coupling. This latter activity is identical to that of the related benzoate 1,2-dioxygenase. A variant anthranilate 1,2-dioxygenase, previously found to convey temperature sensitivity in vivo because of a methionine-to-lysine change in the large oxygenase subunit, was purified and characterized. The purified M43K variant, however, did not hydroxylate anthranilate or benzoate at either the permissive (23°C) or nonpermissive (39°C) growth temperatures. The wild-type anthranilate 1,2-dioxygenase did not efficiently hydroxylate methylated or halogenated benzoates, despite its sequence similarity to broad-substrate specific dioxygenases that do. Phylogenetic trees of the α and β subunits of these terminal dioxygenases that act on natural and xenobiotic substrates indicated that the subunits of each terminal oxygenase evolved from a common ancestral two-subunit component.
Corporate environmental performance evaluation: a measurement model and a new concept

While many third-party organizations are practically evaluating corporate environmental performance (CEP), few academic studies have paid attention to third-party environmental performance evaluation (EPE). To answer the question of what should be measured for third-party EPE, we develop an environmental performance measurement (EPM) model consisting of environmental management performance (EMP) and environmental operational performance (EOP), and hypothesize that EMP be measured by four management performance indicators (MPIs: organizational system, stakeholder relations, operational countermeasures and environmental tracking) and EOP be measured by two operational performance indicators (OPIs: inputs and outputs). Further, to answer the question of how to enable third-party EPE comparable across companies from different (sub-)sectors, we propose to use the environmental intensity change index (EICI) as a measure of OPIs. Empirical tests confirm that the EICI and the evaluation based on it are comparable across companies from different sub-sectors. Empirical tests also support the existence of the MPIs and OPIs and the two-dimensioned constructs of CEP. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.
