Characteristics of consumers using ‘better for you’ front-of-pack food labelling schemes – an example from the Australian Heart Foundation Tick
Authors: Williams Susan L , Mummery Kerry W 
Published: November 2012

AbstractObjectiveThe Heart Foundation Tick aims to help consumers make healthier food choices and overcome confusion in understanding food labels. Little is known about what factors differentiate frequent from infrequent users and the effectiveness of this scheme in helping Australians make healthier food choices.DesignA cross-sectional survey was used to explore use of the Tick and associations with a range of individual characteristics.SettingA national panel of Australians, living in each state and territory, completed an online survey (n1446).SubjectsAdult men (41 %) and women participated in the study.ResultsMost trusted the Heart Foundation (79 %), and used the Tick at least occasionally (19 % regularly, 21 % often, 35 % occasionally, 24 % never). A majority was classified as overweight/obese (60 %), 3·5 % were diagnosed with CHD, 5·2 % with diabetes and 23 % with hypertension. Many did not meet recommendations for the consumption of red meat (30 %), processed meat (23 %), vegetables (78 %), fruit (43 %) and fast foods (47 %). Female frequent users tended to have hypertension, be married/de facto, older than 45 years, rural dwellers, and limit their intake of fast foods. Male frequent users tended to have hypertension, meet recommendations for fruit, vegetables and processed meats, but not have a tertiary education.ConclusionsThe Heart Foundation Tick is a highly trusted, highly recognizable food labelling scheme and helpful to consumers who are motivated to make healthier food choices. More inter-sector collaboration is required to incorporate these schemes into public health campaigns to help consumers make healthier food choices.

Background.To compare Child Behavior Checklist (CBCL) findings for a large Brazilian general population sample with those for US children considering: (a) mean problem item ratings; (b) fit of the US-derived CBCL 8-syndrome model; (c) scale internal consistency measured by Cronbach's alphas; (d) effects of society, age, gender on CBCL problem scores; and (e) ability to discriminate referred from non-referred children.Methods.Parents of 1228 non-referred 6-to-11-year-olds from three different regions of Brazil and 247 referred 6-to-11-year-olds from one clinic rated their children's behavioural and emotional problems using the CBCL/6–18.Results.Results for mean item ratings and scale internal consistencies were very similar to those found in the US and in Uruguay. Confirmatory factor analysis indicated that Brazilian data showed the best fit to the US 8-syndrome model of all countries studied to date. Gender patterns were comparable to those reported in other societies, but mean problem scores for non-referred Brazilian children were higher than those for US children. Therefore, the CBCL discriminated less well between non-referred and referred children in Brazil than in the US.Conclusions.Overall, our findings replicated those reported in international comparisons of CBCL scores for 31 societies, thereby providing support for the multicultural robustness of the CBCL in Brazil.
Large interannual variations in nonmethane volatile organic compound emissions based on measurements of carbon monoxide

Published: November 2012

AbstractWe present source estimates of atmospheric carbon monoxide from nonmethane volatile organic compound (NMVOC) oxidation during a period of 8 years (1997–2004) using a Bayesian inversion analysis. The optimized global NMVOC‐derived CO source strength indicates a change of a factor of 2 between the 1997–1998 strong El Niño and subsequent La Niña conditions. For comparison, the average 8 year interannual variability (IAV) is 18%. The variation of NMVOC‐derived CO is closely correlated with the Oceanic Niño Index (ONI) and surface temperature. A time‐lagged correlation analysis between ONI and NMVOC‐derived CO inventory indicated El Niño/Southern Oscillation leads the Northern Hemisphere (NH) NMVOC‐derived CO production by about 3 months earlier than the Southern Hemisphere's (SH). The SH NMVOC‐derived CO was positively correlated with the lagged‐ONI (r = 0.57), while the temperature change barely influenced SH NMVOC‐derived CO (r = 0.01). In the NH, temperature was more robustly correlated with NMVOC‐derived CO (r = 0.58) than the lagged‐ONI (r = 0.35). In particular, the extra‐tropical temperature showed a strong correlation (r = 0.90) with the NH NMVOC‐derived CO and suggested its primary role in controlling the interannual variability of the NH NMVOC‐derived CO.
Enceladus auroral hiss observations: Implications for electron beam locations
Authors: Leisner J. S. , Hospodarsky G. B. , Gurnett D. A. 
Published: November 2012

AbstractThe Cassini spacecraft has made 20 close flybys of the icy moon Enceladus between its arrival at Saturn in 2004 and 2012. Of those 20, strong whistler mode emissions (often called auroral hiss) were clearly observed on seven encounters. The propagation paths of these emissions are determined by the background magnetic field, which allows their source regions to be studied using simple ray‐tracing codes. In this paper, we trace the auroral hiss observations from Cassini's trajectories to possible source locations near Enceladus. We find that all of the detected emissions could be generated by field‐aligned electron beams in one of two regions around the moon: upstream of the Saturnward terminator and downstream of the anti‐Saturnward terminator. These results suggest that electron beam acceleration near the solid body is a quasi‐time‐stationary feature of the plasma interaction and that the auroral hiss generated by these beams may be used to remotely study plasma processes in regions separated from the spacecraft.
Compact diffraction grating laser wavemeter with sub-picometer accuracy and picowatt sensitivity using a webcam imaging sensor
Authors: White James D. , Scholten Robert E. 
Published: November 2012

We describe a compact laser wavelength measuring instrument based on a small diffraction grating and a consumer-grade webcam. With just 1 pW of optical power, the instrument achieves absolute accuracy of 0.7 pm, sufficient to resolve individual hyperfine transitions of the rubidium absorption spectrum. Unlike interferometric wavemeters, the instrument clearly reveals multimode laser operation, making it particularly suitable for use with external cavity diode lasers and atom cooling and trapping experiments.
New method to assess the loss parameters of the photovoltaic modules
Authors: Bencherif M. , Chermitti A. 
Published: November 2012

The determination of an effective method able to estimate the parameters of a photovoltaic panel is essential for the development and the performance of analysis of such equipment. In this paper, we present a new simple and effective method in order to extract the parameters of the photovoltaic (PV) modules by using the standard diode model. This model requires the five parameters be known, the photocurrent Iph, the reverse saturation current Is, the resistance Rs, the shunt resistance Rsh, and the curve fitting parameter A (the ideality factor) or the thermal voltage a. In order to find the five parameters, we formulated an equation binding only the two loss parameters Rs and Rsh. In order to solve this equation and to determine the shunt resistance and the thermal voltage, we expose the computation models of the series resistance Rs, which give excellent approximations. While the other parameters Iph and Is depend exclusively on the parameters Rs, Rsh, a, and the short circuit current Isc, and the open circuit voltage Voc. This method is validated experimentally by three different flat plat PV modules of various technologies (monocrystalline, polycrystalline, and thin film panels) and manufacturers.

Published: November 2012

Significance
Successful social interaction depends on the ability to recognize others, evaluate their mental states (e.g. intentions, desires, and beliefs), and “read” their emotional states. Here, we show that, in monkeys, damage to the amygdala, a brain structure that is central to the expression of emotion, significantly disrupts the processing of emotional facial expression in high-level visual cortical areas involved in face recognition. These findings suggest that the projections of the amygdala to visual cortical areas likely enhance the sensory processing of biologically important signals, including those related to potential environmental threats and social contexts.
GENERATION IN ITSELF OR FOR ITSELF?
Authors: May Christina 
Published: November 2012

ABSTRACT
The concept of welfare generation and the idea of possible conflicts between generations have been discussed frequently in the context of pension systems. In order to form interest groups that could engage in such a conflict, the generations in question would have to form clear collectives with strong agendas. This article shows that the concept of generation is rather vague and that it is not possible to define a generational collective characterised by its experiences with and attitudes towards the welfare state or the pension system. Pensioner cohorts have so far been identified mainly on the basis of financial transactions. If other resources and characteristics are taken into account, the seemingly clear-cut differences between generations get blurred. Apart from these external factors, there is also no evidence to be found for specific generations perceiving themselves as winners or losers, nor do they show an outspoken conflict potential that would mark them as actors in generational disputes.

Objective.To describe antimicrobial resistance patterns for healthcare-associated infections (HAIs) reported to the National Healthcare Safety Network (NHSN) during 2009-2010.Methods.Central line-associated bloodstream infections, catheter-associated urinary tract infections, ventilator-associated pneumonia, and surgical site infections were included. Pooled mean proportions of isolates interpreted as resistant (or, in some cases, nonsusceptible) to selected antimicrobial agents were calculated by type of HAI and compared to historical data.Results.Overall, 2,039 hospitals reported 1 or more HAIs; 1,749 (86%) were general acute care hospitals, and 1,143 (56%) had fewer than 200 beds. There were 69,475 HAIs and 81,139 pathogens reported. Eight pathogen groups accounted for about 80% of reported pathogens: Staphylococcus aureus (16%), Enterococcus spp. (14%), Escherichia coli (12%), coagulase-negative staphylococci (11%), Candida spp. (9%), Klebsiella pneumoniae (and Klebsiella oxytoca; 8%), Pseudomonas aeruginosa (8%), and Enterobacter spp. (5%). The percentage of resistance was similar to that reported in the previous 2-year period, with a slight decrease in the percentage of S. aureus resistant to oxacillins (MRSA). Nearly 20% of pathogens reported from all HAIs were the following multidrug-resistant phenotypes: MRSA (8.5%); vancomycin-resistant Enterococcus (3%); extended-spectrum cephalosporin-resistant K. pneumoniae and K. oxytoca (2%), E. coli (2%), and Enterobacter spp. (2%); and carbapenem-resistant P. aeruginosa (2%), K. pneumoniae/oxytoca (<1%), E, coli (<1%), and Enterobacter spp. (<1%). Among facilities reporting HAIs with 1 of the above gram-negative bacteria, 20%-40% reported at least 1 with the resistant phenotype.Conclusion.While the proportion of resistant isolates did not substantially change from that in the previous 2 years, multidrug-resistant gram-negative phenotypes were reported from a moderate proportion of facilities.
Are Close Friends the Enemy? Online Social Networks, Self-Esteem, and Self-Control
Authors: Wilcox Keith , Stephen Andrew T. 
Published: November 2012

Abstract
Online social networks are used by hundreds of millions of people every day, but little is known about their effect on behavior. In five experiments, the authors demonstrate that social network use enhances self-esteem in users who are focused on close friends (i.e., strong ties) while browsing their social network. This momentary increase in self-esteem reduces self-control, leading those focused on strong ties to display less self-control after browsing a social network. Additionally, the authors present evidence suggesting that greater social network use is associated with a higher body mass index and higher levels of credit card debt for individuals with strong ties to their social network. This research extends previous findings by demonstrating that social networks primarily enhance self-esteem for those focused on strong ties during social network use. Additionally, this research has implications for policy makers because self-control is an important mechanism for maintaining social order and well-being.

Abstract
We report that the Fe-rich single-phase Sr2Fe1+x
Mo1−x
O6(x = 1/9, 1/6 and 1/3) ceramics can be synthesized in a N2 stream by the solid-state reaction method, while the usual Sr2FeMo2O6 (i.e. x = 0) can only be synthesized in a H2+Ar stream. X-ray diffraction shows that all ceramics are well crystallized with tetragonal symmetry. X-ray photoelectron spectroscopy results confirm that the chemical states of interior Fe and Mo cations are significantly more complex than those of the surface cations. With the increase in x, the materials change from ferrimagnetic (x = 0, 1/9, 1/6) to spin-glass-like behaviour (x = 1/3) and the magnetism decreases dramatically. The Curie temperature (T
c) and the magnetoresistance (MR) at 10 K with a field of 2 T (T
c, MR) are (400 K, −20.9%), (390 K, −10.3%) and (385 K, −4.5%) for x = 0, 1/9 and x = 1/6, respectively. The results are further analysed by Monte Carlo simulations. Our results show that high-T
c ferrimagnetic double perovskites with good magnetic and transport properties can be obtained conveniently in a N2 stream instead of conventional H2+Ar, which not only provides a safe and low-cost way to synthesize these materials, but may also be helpful in decreasing the oxygen vacancy concentration.

Published: November 2012

Abstract
In this study, the spectral emission of Eu3+-doped silica optical fibres is investigated under irradiation with photons and electrons of different energies, field sizes and orientations, in order to discover the origin of stem effect and evaluate its influence on the radioluminescence (RL) spectral shape under experimental conditions. A comparison with previously investigated Ce-doped silica fibres is also made. Below the Cerenkov radiation energy threshold, a slight contribution to the total RL signal is observed. This is due to fluorescence effects occurring in the passive fibre. Above the energy threshold, the stem effect is mainly caused by Cerenkov radiation. A method for removing the stem effect, based on RL spectral analysis, is proposed and validated by measuring the output factors of extended photon fields and by studying the angular dependence of the dosimeter.
Investigations of a thermal plasma jet structure by generalized correlation dimension
Authors: Gruber J , Hlína J , Šonský J 
Published: November 2012

Abstract
Dynamics of thermal plasma jets is characterized by significant turbulent phenomena influencing various technological applications. In two types of experiments, we have analysed (i) tomographical reconstructions of plasma jet radiation captured from four sides by photodiode arrays in two planes perpendicular to the jet axis and (ii) recordings of the jet radiation acquired by a high-speed CCD camera. The analysis was based on the method of generalized correlation dimension stemming from the correlation dimension estimates by the Grassberger–Procaccia algorithm common in the domain of nonlinear dynamic systems. Our results map spatial distributions of complexity within recorded data including their temporal evolution and provide more information about the jet dynamics than, e.g., calculations of standard deviations. The most stable region of the plasma jet was identified at a small distance from the jet axis and the most turbulent region about 4 mm from the plasma torch nozzle. Signs of short-time collective rotational movement of the jet core were also identified.
Structure and colossal dielectric permittivity of Ca2TiCrO6 ceramics
Authors: Yan-Qing Tan , Meng Yan , Yong-Mei Hao 
Published: November 2012

Abstract
A colossal permittivity ceramic material, Ca2TiCrO6, was successfully synthesized by the conventional solid-state reaction, and was characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), x-ray photoemission spectroscopy (XPS) and x-ray diffraction (XRD). Rietveld refinement of XRD data indicated that the material crystallized in orthorhombic structure with space group pbnm. SEM displayed Ca2TiCrO6 ceramic grains packed uniformly with the size range 5–20 µm. XPS analyses indicated that elemental chromium and titanium of the material were in mixed valence. The corresponding dielectric property was tested in the frequency range 1 kHz–1 MHz and the temperature range 213–453 K, and the ceramics exhibited a relaxation-like dielectric behaviour. Importantly, the permittivity of Ca2TiCrO6 could reach 80 000 at 298 K (100 Hz) and was maintained at 40 000 up to 398 K at 1 MHz, which could be attributed to the ion disorder and mixed valence of Cr3+/Cr6+ and Ti3+/Ti4+.

AimsInvasive assessment of acute haemodynamic response to biventricular pacing has been proposed as a tool to determine individual response and to optimize the effects of CRT. However, the long‐term results of this approach have been poorly studied. The present study relates acute haemodynamic effects of CRT to long‐term outcome.Methods and resultsForty‐one patients were analysed in the present study. During temporary biventricular pacing before implantation, acute changes in LV pump function were assessed by pressure–volume loop measurements and related to long‐term response after CRT. In the study population [30 (71%) men, NYHA class 2.9 ± 0.4, EF 28 ± 7%, QRS 150 ± 25 ms], baseline mean stroke work (SW) and dP/dtmax were 4.6 ± 2.6 L ×mmHg and 874 ± 259 mmHg/s, respectively. During biventricular pacing, mean SW and dP/dtmax increased significantly by 43 ± 39% (+ 2.2 ± 2.4 L × mmHg, P < 0.001) and 13 ± 18% (+ 96 ± 136 mmHg/s, P < 0.001), respectively. In long‐term responders (n = 29, 71%) compared with non‐responders (n = 12, 29%), the acute increase in SW was significantly higher (+57 ±33% vs. + 10 ±30%, P < 0.001), whereas the acute increase in dP/dtmax was not significantly different between responders and non‐responders (+ 15 ±18% vs. 6 ±15%, P = 0.139). Receiver operating characteristic (ROC) curve analysis indicated that SW was superior to dP/dtmax, QRS duration and LV dyssynchrony in prediction of response to CRT. A cut‐off value for SW of 20% yielded a sensitivity of 90% and specificity of 75% to predict reverse remodelling at 6 months.ConclusionInvasive assessment of acute haemodynamics is a reliable tool to determine individual response to CRT. An acute increase in SW predicts long‐term response to CRT with a higher accuracy than an acute increase in dP/dtmax, baseline QRS duration, and degree of LV mechanical dyssynchrony.

AimsMutations in the lamin A/C gene (LMNA) cause a variety of clinical phenotypes, including dilated cardiomyopathy. LMNA is one of the most prevalent mutated genes in dilated cardiomyopathy, and is associated with a high risk of arrhythmias, sudden cardiac death, and heart failure. There are few data on the impact of age and gender on cardiac disease penetrance and mortality.Methods and resultsIn a multicentre cohort of 269 LMNA mutation carriers, we evaluated gender‐specific penetrance of cardiac involvement and major cardiac events. All‐cause mortality of mutation carriers [standardized mortality ratio (SMR)] was determined. Cardiac disease penetrance was age dependent and almost complete at the age of 70 years. The presence of an LVEF ≤45% was significantly higher in men (P < 0.001). However, there was no difference between genders in the prevalence of atrioventricular block, atrial tachyarrhythmias, and non‐sustained ventricular tachycardia. Malignant ventricular arrhythmias (26% vs. 8%) and end‐stage heart failure (28% vs. 14%) were more common in men than in women (P < 0.001 and P = 0.006, respectively). All‐cause mortality of mutation carriers was significantly increased [SMR 4.0, 95% confidence interval (CI) 2.8–5.2] between the ages of 15 and 75 years. Mortality in men was higher than in women (hazard ratio 2.2, 95% CI 1.2–4.3).ConclusionsThis large cohort of LMNA mutation carriers demonstrates a high cardiac disease penetrance and a high mortality in mutation carriers. Male mutation carriers have a worse prognosis due to a higher prevalence of malignant ventricular arrhythmias and end‐stage heart failure.
