Silence and secrets in Domenico Fetti's Portrait of a Man with a Sheet of Music
Authors: ROBERTS SEAN 
Published: February 2012

Domenico's Fetti's Portrait of a Man with a Sheet of Music has confounded attempts to identify its sitter and perplexed viewers with its unexplained narrative. The foreground presents a seated man who glances up from the page in his left hand. At the lower right corner of the canvas, two small figures emerge from a doorway. The first of these men points to the sitter, while the other puts a single finger to his lips, his head turned right to address an unseen presence beyond the frame. With this gesture, he hushes both his fictive companion and the viewer.This essay re‐examines both the identity of Fetti's sitter and, more importantly, the role of these painted intruders. I argue that the marginal figure's gesture of silence serves to thematize visual art's always fraught relationship with sound. Further, I propose that early modern viewers would have associated this gesture with admonitions to discretion and secrecy. This novel rumination on silence and secrets would have proved ideal for the representation of a new and socially liminal class of musical theatre composers and performers at the Mantuan court that Fetti served.

AbstractRoutine serological testing for hepatitis C virus (HCV) infection among hemodialysis (HD) patients is currently recommended. A dilemma existed on the value of serology because some investigators reported a high rate of false‐negative serologic testing. In this study, we aimed to detect the false‐negative rate of anti‐HCV among Egyptian HD patients. Seventy‐eight HD patients, negative for anti‐HCV, anti‐HIV, and hepatitis B surface antigen, were tested for HCV RNA by reverse transcriptase polymerase chain reaction (RT‐PCR). In the next step, the viral load was quantified by real‐time PCR in RT‐PCR‐positive patients. Risk factors for HCV infection, as well as clinical and biochemical indicators of liver disease, were compared between false‐negative and true‐negative anti‐HCV HD patients. The frequency of false‐negative anti‐HCV was 17.9%. Frequency of blood transfusion, duration of HD, dialysis at multiple centers, and diabetes mellitus were not identified as risk factors for HCV infection. The frequency of false‐negative results had a linear relation to the prevalence of HCV infection in the HD units. Timely identification of HCV within dialysis units is needed in order to lower the risk of HCV spread within the HD units. The high false‐negative rate of anti‐HCV among HD patients in our study justifies testing of a large scale of patients for precious assessment of effectiveness of nucleic acid amplification technology testing in screening HD patient.

AbstractAmyloid fibrils can affect vascular structure through deposition and by causing nitric oxide depletion and increase of asymmetric dimethyl arginine. Patients with amyloidosis are prone to development of hypotension. Hypotension may also affect the maturation of arteriovenous fistula (AVF) and may set the stage for formation of thrombosis and fistula failure. Thus, we aimed to evaluate effects of secondary amyloidosis on AVF outcomes and intradialytic hypotension. This is a case‐control study which included 20 hemodialysis patients with amyloidosis and 20 hemodialysis patients without amyloidosis as control group. All patients underwent Doppler ultrasound of AVF. A thorough fistula history and baseline laboratory values along with episodes of intradialytic hypotension and blood pressure measurements were recorded. There was no difference between the groups regarding age, gender, body mass index, presence of comorbidities, hypertension, and drug use. Systolic and diastolic blood pressures were similar (119 ± 28/75 ± 17 and 120 ± 14/75 ± 10 mmHg for patients with and without amyloidosis, respectively). Intradialytic hypotension episodes were also similar. Patients with amyloidosis had significantly lower serum albumin and higher C‐reactive protein values compared to control hemodialysis patients. AVF sites and total number of created fistulas were similar in both groups. Flow rates of current functional AVFs were not different between the groups (1084 ± 875 and 845 ± 466 mL/minute for patients with and without amyloidosis, respectively, p:0.67). Patency duration of first AVF was not different between the groups. Clinical fistula outcomes and rate of intradialytic hypotension episodes were not significantly different between patients with and without secondary systemic amyloidosis.
Dielectric Properties of Solution‐Deposited Crystalline Barium Titanate Thin Films
Authors: Roy Biplab Kumar , Cho Junghyun 
Published: February 2012

We have developed a “two‐step” solution‐based processing to deposit high‐k ceramic thin films. Electrochemically pre‐coated amorphous titania layers were “hydrothermally” or “hydrothermal‐electrochemically” converted to crystalline BaTiO3 films at ≤90°C. In hydrothermal process, an in situ electrochemical protection (ECP) mechanism enables utilization of common metallic substrates (e.g., Cu), which otherwise suffer corrosion from the precursor. Microstructural evolution of BaTiO3 films along with the effectiveness of ECP is discussed in this article. Derived BaTiO3 shows a dielectric constant of ~80 at 100 kHz, which makes it a promising candidate for high‐density microelectronic capacitor applications.
Crystal Structures and Dielectric Properties of Bi2((Zn1/3Nb2/3)1−xTix)2O7 Ceramics

Published: February 2012

Bi2((Zn1/3Nb2/3)1−xTix)2O7 ceramics with 0 ≤ x ≤ 0.4 were synthesized using solid‐state reaction method. The crystal structure is pure zirconolite type for the compositions with 0 ≤ x ≤ 0.15, single weberite type for the compositions with 0.3 ≤ x ≤ 0.4, and mixture of zirconolite and weberite for the compositions with 0.15 < x < 0.3. The weberite ceramics with only Bi as the A‐site cation are first reported. A possible correlation between the crystal structure transformation and Ti content in system of Bi2((Zn1/3Nb2/3)1−xTix)2O7 with 0 ≤ x ≤ 0.4 was suggested. Dielectric constant (ε), dielectric loss (tan δ) and temperature coefficient of capacitance (TCC) are ~85, ~0.001, and ~200 ppm/°C for the zirconolite solid solutions, ~140, 0.004, and between −120 and −200 ppm/°C for the weberite solid solutions, respectively, at 1 MHz. Ceramics with a near zero TCC consisting of the zirconolite and weberite phases were obtained. High ε, low tanδ, and low sintering temperatures (~950°C) make the novel ceramic system of Bi2((Zn1/3Nb2/3)1−xTix)2O7 potential dielectrics for applications in low‐temperature co‐fired ceramic and multiplayer ceramic capacitors.

Published: February 2012

The dielectric properties of a new, cubic, pyrochlore‐type solid solution Bi(1.6−1.08x)NdxTi2O(6.4−0.11x) have been studied across the compositional range 0.35 < x < 0.86. The dielectric constant (ε) of the ceramics based on the pyrochlore‐type solid solution within the experimental compositional range varied from 104 to 76 at 1 MHz, whereas the dielectric losses were well below tan δ = 8 × 10−3. The temperature coefficient of the dielectric constant τk for single‐phase pyrochlore samples was found to be in the range between −20 and −40 ppm/K. Below room temperature dielectric relaxation phenomena were observed for all the compositions.
Trade union influence in Spanish manufacturing firms
Authors: GARCÍA OLAVERRI Carmen , HUERTA Emilio 
Published: February 2012

Abstract.Based on surveys conducted in 1996 and 2007, this article examines the relationship between trade union influence, as perceived by management, and human resource policy and productivity in Spanish enterprises with over 50 employees. It investigates whether trade unions use their influence to pursue the agenda they have traditionally professed to uphold or whether outcomes differ in practice. The authors identify positive correlations between trade union influence and both wages and absenteeism, but union influence appears to have no effect on the incidence of casual employment, the provision of training, work–life balance policies or information sharing within enterprises.

Economic and social upgrading in global production networks: Problems of theory and measurement
Authors: MILBERG William , WINKLER Deborah 
Published: February 2012

Abstract.Economic development has increasingly become synonymous with “economic upgrading” within global production networks (GPNs). Yet, while there has been much research on connecting economic upgrading with economic growth and international trade, there has been less analysis of the relationship between economic and “social upgrading”, i.e. improvements in the wages, conditions, rights, gender equality and economic security of workers in GPNs. Focusing on developing countries, this article reviews the ways in which economic and social upgrading are measured and scrutinizes the theoretical connection between these two dimensions of upgrading. The authors conclude with a brief discussion of policy implications.

Published: February 2012

Abstract Purpose:To discuss a case of scrub typhus complicated with acute respiratory distress syndrome (ARDS) in a 67‐year‐old female. An overview of the prevalence and pathogenesis of the disorder, clinical diagnosis, and treatment are presented.Data sources:Case report, diagnostic evidence, and scientific literature.Conclusions:If not properly treated, scrub typhus can cause serious complications, such as ARDS and septicemia. When left untreated, the mortality rate for scrub typhus will be increased. When there is a cause to believe that scrub typhus is present, doxycycline treatment leads to rapid symptom improvement.Implications for practice:People might not be aware of the possibility of scrub typhus because it had been a more common disease in the past. Nurse practitioners (NPs) should take a detail history and be aware of common clinical manifestations to promote the early recognition and appropriate treatment of scrub typhus, which would prevent severe complications and reduce mortality. A resurgence of the disease could occur at any time among military troops serving in endemic regions.

AbstractIntroduction:  Inhaled corticosteroids (ICS) and oral leukotriene receptor antagonists (LTRA) are effective drugs used in the management of asthma as controller monotherapy in adolescents and adults, although there are debates as to which one is better.Objectives:  To thoroughly compare the efficacy and tolerability of ICS vs LTRA in adolescents and adults with mild to moderate asthma.Methods:  Relative database were searched for the review. Randomized controlled trials of more than or equal to 4 weeks' treatment duration comparing ICS with LTRA were reviewed.Results and Conclusion:  Twenty‐four trials with 6197 randomized adolescents and adults with mild to moderate asthma met the inclusion criteria with a minimum duration of 4 weeks' treatment. Significant differences favouring ICS were found in all indices of pulmonary function. Other significant benefits of ICS were shown in symptoms, nocturnal awakenings, rescue‐medication use, symptom‐free days and quality of life. As to each special symptom of adverse effects, ICS was similar to LTRA in the incidence of headache, nausea and throat discomfort, but significantly higher in the incidence of hoarseness and oral pharyngeal candidiasis. Concerning withdrawal because of adverse events potentially related to treatment, ICS was similar to LTRA but significantly superior to LTRA in decreasing the asthma exacerbations or attacks during the treatment period. These results show that ICS may be the better drug in terms of efficacy and tolerability, except hoarseness and oral pharyngeal candidiasis, and should thus have priority over LTRA in asthma monotherapy in adolescents and adults.Please cite this paper as: Yang D, Luo H, Wang J, Bunjhoo H, Xu Y and Xiong W.

ABSTRACTImmigration issues can complicate the already difficult decisions that face family courts, and immigration law is a real and substantial element in the lives of many persons properly before family courts for protection and resolution of family issues. Yet there are not established parameters for evaluating the appropriateness and scope of the consideration of immigration issues in family court. This article explores principles and approaches regarding immigration issues in family courts, developing rationales for engaging or not in immigration issues, and providing a foundation for thoughtful consideration of the ways in which immigration law interacts with core family law functions.
Carbon sequestration in soil in a semi‐natural Miscanthus sinensis grassland and Cryptomeria japonica forest plantation in Aso, Kumamoto, Japan

AbstractAlthough Miscanthus sinensis grasslands (Misc‐GL) and Cryptomeria japonica forest plantations (Cryp‐FP) are proposed bioenergy feedstock systems, their relative capacity to sequester C may be an important factor in determining their potential for sustainable bioenergy production. Therefore, our objective was to quantify changes in soil C sequestration 47 years after a Misc‐GL was converted to a Cryp‐FP. The study was conducted on adjacent Misc‐GL and Cryp‐FP located on Mt. Aso, Kumamoto, Japan. After Cryp‐FP establishment, only the Misc‐GL continued to be managed by annual burning every March. Mass C and N, δ13C, and δ15N at 0–30 cm depth were measured in 5 cm increments. Carbon and N concentrations, C:N ratio, δ13C, and δ15N were measured in litter and/or ash, and rhizomes or roots. Although C input in Misc‐GL by M. sinensis was approximately 36% of that in Cryp‐FP by C. japonica, mean annual soil C sequestration in Misc‐GL (503 kg C ha−1 yr−1) was higher than that in Cryp‐FP (284 kg C ha−1 yr−1). This was likely the result of larger C input from aboveground litter to soil, C‐quality (C:N ratio and lignin concentration in aboveground litter) and possibly more recalcitrant C (charcoal) inputs by annual burning. The difference in soil δ15N between sites indicated that organic C with N had greater cycling between heterotrophic microbes and soil and produces more recalcitrant humus in Misc‐GL than in Cryp‐FP. Our data indicate that in terms of soil C sequestration, maintenance of Misc‐GL may be more advantageous than conversion to Cryp‐FP in Aso, Japan.
Recent developments in the obstetric use of cell salvage
Authors: PEACOCK LINZI , CLARK VICKI , CATLING SUE 
Published: February 2012

SUMMARYThe acceptance of cell salvage in obstetrics has been hampered by concerns about amniotic fluid embolism and maternal alloimmunization. The removal of amniotic fluid debris by cell salvage has been proven, but controversy remains as to whether using one or two separate suction devices for removal of amniotic fluid and blood is necessary. There have been recent reports of hypotensive episodes occurring during re‐infusion of the salvaged blood with leukodepletion filters. Bradykinin release may be the responsible agent. Maternal alloimmunization can potentially occur as the cell saver cannot differentiate between maternal and fetal red cells. However, the fetal cell transference rate in salvaged blood is of the same magnitude as during a feto‐maternal hemorrhage and can be treated by appropriate administration of anti‐D. Salvaged blood does not contain any coagulation factors and in massive hemorrhage these factors must be replaced in addition to the red cells. Coagulopathy in bleeding patients that have cell salvage should not be viewed as an adverse event associated with this technique, but rather as inadequate replacement of coagulation products. There is currently no evidence base that cell salvage in obstetrics reduces allogeneic transfusion or is cost‐effective. A randomized controlled trial is urgently needed.
Inventive Megaregions of the United States: Technological Composition and Location
Authors: hUallacháin Breandán Ó 
Published: February 2012

abstractUrban distinctiveness occurs in both technological and geographic space. This article explores spatial associations in the locational distribution of subcategories of patents across U.S. metropolitan areas. I converted patent counts to location quotients and used nonspatial methods to compare concentration levels of patents (Gini coefficients) and to identify groups of patents that tend to colocate (principal components analysis). The results show considerable variation in concentration levels and that nine groupings, entitled “technology components,” account for almost 68 percent of the variance in the distribution of the subcategories. Spatial analysis permits the exploration of spatial dependencies in each “technology component.” The results identify distinctive inventive regions that are termed inventive megaregions.
Multiple Biomarkers for Risk Prediction in Chronic Heart Failure
Authors: Ky Bonnie , French Benjamin , Levy Wayne C. , Sweitzer Nancy K. , Fang James C. , Wu Alan H.B. , Goldberg Lee R. , Jessup Mariell , Cappola Thomas P. 
Published: February 2012

Background—
Prior studies have suggested using a panel of biomarkers that measure diverse biological processes as a prognostic tool in chronic heart failure. Whether this approach improves risk prediction beyond clinical evaluation is unknown.

Methods and Results—

In a multicenter cohort of 1513 chronic systolic heart failure patients, we measured a contemporary biomarker panel consisting of high-sensitivity C-reactive protein, myeloperoxidase, B-type natriuretic peptide, soluble fms-like tyrosine kinase receptor-1, troponin I, soluble toll-like receptor-2, creatinine, and uric acid. From this panel, we calculated a parsimonious multimarker score and assessed its performance in predicting risk of death, cardiac transplantation, or ventricular assist device placement in comparison to an established clinical risk score, the Seattle Heart Failure Model (SHFM). During a median follow-up of 2.5 years, there were 317 outcomes: 187 patients died; 99 were transplanted; and 31 had a ventricular assist device placed. In unadjusted Cox models, patients in the highest tertile of the multimarker score had a 13.7-fold increased risk of adverse outcomes compared with the lowest tertile (95% confidence interval, 8.75–21.5). These effects were independent of the SHFM (adjusted hazard ratio, 6.80; 95% confidence interval, 4.18–11.1). Addition of the multimarker score to the SHFM led to a significantly improved area under the receiver operating characteristic curve of 0.803 versus 0.756 (
P
=0.003) and appropriately reclassified a significant number of patients who had the outcome into a higher risk category (net reclassification improvement, 25.2%; 95% confidence interval, 14.2–36.2%;
P
<0.001).

Conclusions—
In ambulatory chronic heart failure patients, a score derived from multiple biomarkers integrating diverse biological pathways substantially improves prediction of adverse events beyond current metrics.

Published: February 2012

Background and Purpose—
Ischemic stroke (IS) shares many common risk factors with coronary artery disease (CAD). We hypothesized that genetic variants associated with myocardial infarction (MI) or CAD may be similarly involved in the etiology of IS. To test this hypothesis, we evaluated whether single-nucleotide polymorphisms (SNPs) at 11 different loci recently associated with MI or CAD through genome-wide association studies were associated with IS.

Methods—
Meta-analyses of the associations between the 11 MI-associated SNPs and IS were performed using 6865 cases and 11 395 control subjects recruited from 9 studies. SNPs were either genotyped directly or imputed; in a few cases a surrogate SNP in high linkage disequilibrium was chosen. Logistic regression was performed within each study to obtain study-specific βs and standard errors. Meta-analysis was conducted using an inverse variance weighted approach assuming a random effect model.

Results—
Despite having power to detect odds ratio of 1.09–1.14 for overall IS and 1.20–1.32 for major stroke subtypes, none of the SNPs were significantly associated with overall IS and/or stroke subtypes after adjusting for multiple comparisons.

Conclusions—
Our results suggest that the major common loci associated with MI risk do not have effects of similar magnitude on overall IS but do not preclude moderate associations restricted to specific IS subtypes. Disparate mechanisms may be critical in the development of acute ischemic coronary and cerebrovascular events.
