Purpose This study was undertaken to determine the magnitude of pulmonary dysfunction in childhood cancer survivors when compared with healthy controls and the extent (and predictors) of decline over time. Patients and Methods Survivors underwent baseline (t1) pulmonary function tests, followed by a second comprehensive evaluation (t2) after a median of 5 years (range, 1.0 to 10.3 years). Survivors were also compared with age- and sex-matched healthy controls at t2. Results Median age at cancer diagnosis was 16.5 years (range, 0.2 to 21.9 years), and time from diagnosis to t2 was 17.1 years (range, 6.3 to 40.1 years). Compared with odds for healthy controls, the odds of restrictive defects were increased 6.5-fold (odds ratio [OR], 6.5; 95% CI, 1.5 to 28.4; P < .01), and the odds of diffusion abnormalities were increased 5.2-fold (OR, 5.2; 95% CI, 1.8 to 15.5; P < .01). Among survivors, age younger than 16 years at diagnosis (OR, 3.0; 95% CI, 1.2 to 7.8; P = .02) and exposure to more than 20 Gy chest radiation (OR, 5.6; 95% CI, 1.5 to 21.0; P = .02, referent, no chest radiation) were associated with restrictive defects. Female sex (OR, 3.9; 95% CI, 1.7 to 9.5; P < .01) and chest radiation dose (referent: no chest radiation; ≤ 20 Gy: OR, 6.4; 95% CI, 1.7 to 24.4; P < .01; > 20 Gy: OR, 11.3; 95% CI, 2.6 to 49.5; P < .01) were associated with diffusion abnormalities. Among survivors with normal pulmonary function tests at t1, females and survivors treated with more than 20 Gy chest radiation demonstrated decline in diffusion function over time. Conclusion Childhood cancer survivors exposed to pulmonary-toxic therapy are significantly more likely to have restrictive and diffusion defects when compared with healthy controls. Diffusion capacity declines with time after exposure to pulmonary-toxic therapy, particularly among females and survivors treated with high-dose chest radiation. These individuals could benefit from subsequent monitoring.

Published: April 2015

Abstract
Y3+- and La3+-doped zeolitic imidazolate frameworks-8 (ZIF-8) crystals were first successfully prepared by hydrothermal synthesis. As-synthesized crystals were investigated by X-ray diffraction, field-emission scanning electron microscope, fluorescence spectrometric titration, and gas adsorption measurement. The Y3+-doped ZIF-8 crystals were found to be highly sensitive to amines (ethylamine, diethylamine, and triethylamine), providing a novel candidate for the sensitive and rapid detection of amines.

Binge drinking and cognitive impairment in young people
Authors: Thayanukulvat Claire , Harding Tracey 
Published: April 2015

Aims and objectives: To investigate the links between the binge pattern of drinking and the development of cognitive impairment in young adults in the UK. To determine from the findings whether cognitive impairment is an additional public health concern manifesting from this form of alcohol misuse and its relevance to nursing practice. Background: Young adults in the UK are participating in binge drinking; a ‘harmful’ form of alcohol misuse. Morbidity and mortality associated with alcohol misuse is already a public health concern. Design: Literature review. Method: Multiple database searches were undertaken, which revealed three case-control studies. The studies all investigated the binge pattern of drinking as well as meeting the following inclusion criteria; primary research published from 2005 onwards, used a human sample, participants were aged 18 to 24 and cognitive function was tested. Results: The quantitative data found cognitive impairment present in young adult binge drinkers, specifically in regions of the frontal lobe, temporal lobe and hippocampus. Individually the studies did not pose strong enough evidence to generalise findings. However, collectively the core findings along with previous studies can validate the link between binge drinking and cognitive impairment. Conclusion: Nurse-led alcohol misuse screening and brief intervention is the most effective public health prevention strategy. It is important for nurses to keep abreast of current evidence to better inform their practice and the information they provide to their service users. This review emphasises the need for nurses to routinely screen young adults and address the associated risk to cognitive function when participating in harmful drinking.
Almost soliton duality
Authors: Maschler Gideon 
Published: April 2015

Abstract
Gradient Ricci almost solitons were introduced by Pigola, Rigoli, Rimoldi and Setti [20]. They are defined as solitons except that the metric coefficient is allowed to be a smooth function rather than a constant. It is shown that any almost soliton is conformal to another almost soliton having a soliton function which is the negative of the original one. Uniqueness, and the case where both the source and target are solitons, are studied. Completeness of the target metric is also examined in the casewhere the source is Kähler and admits a special Kähler-Ricci potential in the sense of [10; 11].
Remarks on Kähler–Ricci solitons
Authors: Bedulli Lucio , Gori Anna 
Published: April 2015

Abstract
We prove that a compact complex manifold endowed with a Kähler-Ricci soliton cannot be isometrically embedded in a complex projective space ℂℙn in such a way that the Gauss map is rational, unless the metric is Einstein. This applies to hypersurfaces of complex compact homogeneous spaces canonically embedded in ℂℙn.We moreover obtain two curvature constraints for invariant Kähler-Ricci solitons on complex manifolds acted on by a compact Lie group with cohomogeneity one.
Geometric properties of semitube domains
Authors: Kosinski Łukasz , Warszawski Tomasz , Zwonek Włodzimierz 
Published: April 2015

Abstract
We study the geometry of semitube domains in ℂ2, in particular we extend the result of Burgués and Dwilewicz for semitube domains by dropping the smoothness assumption. We also prove various properties of non-smooth pseudoconvex semitube domains, obtaining a relation between pseudoconvexity of a semitube domain and the number of components of its vertical slices. Finally, we present an example of a non-convex domain in ℂn such that its image under arbitrary isometries is pseudoconvex.
Zwischen Leistungsvergleich und Qualitätsentwicklung. Ergebnisse des Round Table „Chancen und Risiken von Leistungsvergleichen für Bibliotheken“ im Herbst 2014
Authors: Bilo Albert , Brockmann Hanno 
Published: April 2015

Zusammenfassung:
Leistungsvergleiche von Kommunen, Hochschulen und Bibliotheken haben nach wie vor Konjunktur, sind zugleich aber auch umstritten. Dies zeigt der aktuelle fachliche und überfachliche Diskurs. Bedarf es gezielter Modifikationen der bisherigen Messinstrumente oder hilft nur eine komplette Neuorientierung? Um einen Blick in die Zukunft von Leistungsvergleichen – insbesondere im Bibliotheksbereich – zu werfen, hat die gemeinsame Managementkommission des Deutschen Bibliotheksverbands und des Vereins Deutscher Bibliothekare am 15. und 16. September 2014 einen Round Table durchgeführt. Der vorliegende Beitrag liefert einen Überblick zu dieser Diskussionsrunde.

Published: April 2015

Zusammenfassung:
Hochschulrankings bilden ein wichtiges Informationsinstrument für Studieninteressierte, Personalverantwortliche und Drittmittelgeber, um in vereinfachter Form die Leistung von Hochschulen durch Rangfolgen miteinander vergleichbar zu machen. Solche Rankings bilden zunehmend ein wichtiges Hilfsmittel, um das Erreichen von Effizienz- und Effektivitätszielen im Vergleich zu anderen Hochschulen zu verfolgen. Für Bibliotheken ist es wichtig, ihre Rolle in solchen Rankings korrekt einschätzen zu können und zu wissen, mit welchen Indikatoren bibliothekarische Leistungen in Hochschulrankings gemessen werden. Mit den so gewonnenen Erkenntnissen können Zielsysteme und Budgetverhandlungen optimiert werden.

Published: April 2015

Zusammenfassung:
Im Kontext des Steuerungsmodells des New Public Management treten Hochschulen zunehmend als organisationale Akteure in Erscheinung, die ihre Entwicklung selber steuern und dafür geeignete Instrumente benötigen. Mit Leistungsvergleichen sind in diesem Zusammenhang vielfältige Erwartungen verbunden und der z. T. hohe Verbreitungsgrad vergleichender Verfahren scheint deren Wirksamkeit zu bestätigen. In dem Beitrag werden die Stärken und Schwächen einzelner Instrumente hinsichtlich der Unterstützung des Steuerungshandelns an Hochschulen untersucht und vergleichend gegenübergestellt.

Published: April 2015

AbstractThe chelating resin was synthesized by free-radical copolymerization of iminodiacetic acid modified glycidyl methacrylate with a cross-linker N,N′-methylene biscarylamide at 70°C for removal of heavy metal ions from aqueous solutions. The equilibrium adsorption capacities of the chelating resin from their single-metal ion solutions were 3.28 mmol/g for Cd(II), 2.36 mmol/g for Cu(II), 1.71 mmol/g for Mn(II), 1.69 mmol/g for Ni(II), 1.41 mmol/g for Zn(II), 1.24 mmol/g for Co(II), 0.78 mmol/g for Cr(III) and 0.66 mmol/g for Pb(II). Their related absorption behaviors are discussed in this paper such as thermodynamic equilibrium, pH effect and the Langmuir and Freundlich model to evaluate the experimental data. According to the results, this resin could be used as a promising adsorbent for industrial wastewater disposal.

Published: April 2015

Abstract
Biological membranes are dynamic and complex assemblies of lipids and proteins. Eukaryotic lipidomes encompass hundreds of distinct lipid species and we have only begun to understand their role and function. This review focuses on recent advances in the field of lipid sensors and discusses methodical approaches to identify and characterize putative sensor domains. We elaborate on the role of integral and conditionally membrane-associated sensor proteins, their molecular mechanisms, and identify open questions in the emerging field of membrane homeostasis.
Numerical Parametric Analysis of Bond Coat Thickness Effect on Residual Stresses in Zirconia-Based Thermal Barrier Coatings
Authors: Abbas Musharaf , Hasham Hasan Junaid , Baig Yasir 
Published: April 2015

AbstractNumerical-based finite element investigation has been conducted to explain the effect of bond coat thickness on stress distribution in traditional and nanostructured yttria-stabilized zirconia (YSZ)-based thermal barrier coatings (TBC). Stress components have been determined to quantitatively analyze the mechanical response of both kinds of coatings under the thermal shock effect. It has been found that maximum radial tensile and compressive stresses that exist at thermally grown oxide (TGO)/bond coat interface and within TGO respectively decrease with an increase in bond coat thickness. Effect of bond coat thickness on axial tensile stresses is not significant. However, axial compressive stresses that exist at the edge of the specimen near bond coat/substrate interface decrease appreciably with the increase in bond coat thickness. Residual stress profile as a function of bond coat thickness is further explained for comparative analysis of both coatings to draw some useful conclusions helpful in failure studies of TBCs.
The Effects of Mechanical Properties on Fatigue Behavior of ECAPed AA7075
Authors: Kaya Hasan , Uçar Mehmet 
Published: April 2015

AbstractIn this study, the effects of equal channel angular pressing (ECAP) on high-cycle fatigue and fatigue surface morphology of AA7075 have been investigated at a constant temperature (483 K) and the “C” route for four passes at ECAP process. ECAPed and as-received specimens were tested by four-point bending fatigue device. Fatigue tests were carried out by using 100, 120 and 140 MPa strength values. ECAPed specimens were characterized for each pass with optical microscope (OM), scanning electron microscope (SEM), energy-dispersive spectroscope (EDS), transmission electron microscope (TEM), selected area electron diffraction (SAED) and hardness measurements. Fracture surfaces of the specimens were also characterized with SEM. The results show that the highest hardness values (137 HV) and the best fatigue life (5.4 × 107for 100 MPa) were measured in ECAPed four-pass sample. For this reason hardness values and fatigue life were increased with increasing number of severe plastic deformation (SPD) process.
Bullying and Zero-Tolerance Policies: The School to Prison Pipeline
Authors: Berlowitz Marvin J. , Frye Rinda , Jette Kelli M. 
Published: April 2015

Abstract
The centrality of zero-tolerance policies as a component of anti-bullying strategies is the focus of this paper. A review of the literature of social justice advocates, journalists, and scholars reveals that zero-tolerance policies tend to push students out of public schools into the criminal justice system in a pattern of institutional racism. This phenomenon has come to be labeled the “school to prison pipeline.” Interviews with teachers and administrators reveal that they see no alternative to their implementation of zero-tolerance policies, because they believe that violent behaviors manifested by racial minority students are grounded in cultural norms beyond the control of public educators. The authors conclude that the “school to prison pipeline” can only be ameliorated by a program of radical reform.
On the Fairness of the Multilateral Trading System
Authors: Brandi Clara 
Published: April 2015

AbstractThree perspectives on international trade are present in current debates. From the first perspective, trade is regarded as a set of individual transactions among consenting parties and considerations of fairness and justice barely feature, if at all. The second perspective underlines the importance of background structures for trade, maintained by states, which gives rise considerations of fairness and justice. One prominent version of this perspective, for example as defended by Aaron James, views all trading states as having in principle equal claims to the gains from trade. A third perspective puts the focus on exploitation. In this special issue, Mathias
Unfair Trade, Exploitation, and Below-Subsistence Wages
Authors: Dänzer Sonja 
Published: April 2015

AbstractThe article discusses the relation between the concepts of unfair trade, exploitation, and below-subsistence wages with regard to individual economic transactions. Starting from the common notion that exploitation involves some kind of unfair advantage taking, it asks how “unfair” is to be understood, and what it is that is taken advantage of in exploitative exchanges. On this basis it then explores a line of argument for grounding the claim that below-subsistence wages are exploitative, focusing on the condition of morally transformative voluntary consent to transactions. By analyzing the structure of coercion with regard to threats, offers, and circumstances it comes to the conclusion that consent to an offer is morally non-transformative with regard to legitimizing the outcome of a transaction if the person giving the “consent” has only unacceptable options in absolute terms to choose from, since this reduces “consent” to a mere act of rationality devoid of any normative content. Accordingly, it argues that insofar as below-subsistence wages are unacceptable options in absolute terms, they are to be considered exploitative and an instance of unfair trade.
Three Images of Trade: On the Place of Trade in a Theory of Global Justice
Authors: Risse Mathias , Wollner Gabriel 
Published: April 2015

AbstractEconomic theory teaches that it is in every country’s interest to trade. Trade is a voluntary activity among consenting parties. On this view, considerations of justice have little bearing on trade, and political philosophers concerned with global justice should stay largely silent on trade. According to a very different view that has recently gained prominence, international trade can only occur before the background of an international market reliance practice shaped by states. Trade is a shared activity among states, and all participating states have in principle equal claims to gains from trade. Trade then becomes a central topic for political philosophers. Both views are problematic. A third view about the role of trade in a theory of global justice is then presented, which gives pride of place to a (non-Marxian) notion of exploitation. The other two views should be abandoned.

Validity of the Strengths and Difficulties Questionnaire in Preschool-Aged Children
Authors: Croft Simone , Stride Christopher , Maughan Barbara , Rowe Richard 
Published: April 2015

BACKGROUND:
The Strengths and Difficulties Questionnaire (SDQ) is widely used to screen for child mental health problems and measure common forms of psychopathology in 4- to 16-year-olds. Using longitudinal data, we examined the validity of a version adapted for 3- to 4-year-olds.

METHODS:
We used SDQ data from 16 659 families collected by the Millennium Cohort Study, which charts the development of children born throughout the United Kingdom during 2000–2001. Parents completed the preschool SDQ when children were aged 3 and the standard SDQ at ages 5 and 7. The SDQ’s internal factor structure was assessed by using confirmatory factor analysis, with a series of competing models and extensions used to determine construct, convergent, and discriminant validity and measurement invariance over time. Predictive validity was evaluated by examining the relationships of age 3 SDQ scores with age 5 diagnostic measures of attention-deficit/hyperactivity disorder, autism spectrum disorder/Asperger syndrome, and teacher-reported measures of personal, social, and emotional development.

RESULTS:
Confirmatory factor analysis supported a 5-factor measurement model. Internal reliability of subscales ranged from ω = 0.66 (peer problems) to ω = 0.83 (hyperactivity). Item-factor structures revealed measurement invariance over time. Strong positive correlations between ages 3 and 5 SDQ scores were not significantly different from correlations between age 5 and 7 scores. Conduct problems and hyperactivity subscales independently predicted developmental and clinical outcomes 2 years later.

CONCLUSIONS:
Satisfactory psychometric properties of the adapted preschool version affirm its utility as a screening tool to identify 3- to 4-year-olds with emotional and behavioral difficulties.
Cow’s Milk Contamination of Human Milk Purchased via the Internet
Authors: Keim Sarah A. , Kulkarni Manjusha M. , McNamara Kelly , Geraghty Sheela R. , Billock Rachael M. , Ronau Rachel , Hogan Joseph S. , Kwiek Jesse J. 
Published: April 2015

BACKGROUND:
The US Food and Drug Administration recommends against feeding infants human milk from unscreened donors, but sharing milk via the Internet is growing in popularity. Recipient infants risk the possibility of consuming contaminated or adulterated milk. Our objective was to test milk advertised for sale online as human milk to verify its human origin and to rule out contamination with cow’s milk.

METHODS:
We anonymously purchased 102 samples advertised as human milk online. DNA was extracted from 200 μL of each sample. The presence of human or bovine mitochondrial DNA was assessed with a species-specific real-time polymerase chain reaction assay targeting the nicotinamide adenine dinucleotide (NADH) dehydrogenase subunit 5 gene. Four laboratory-created mixtures representing various dilutions of human milk with fluid cow’s milk or reconstituted infant formula were compared with the Internet samples to semiquantitate the extent of contamination with cow’s milk.

RESULTS:
All Internet samples amplified human DNA. After 2 rounds of testing, 11 samples also contained bovine DNA. Ten of these samples had a level of bovine DNA consistent with human milk mixed with at least 10% fluid cow’s milk.

CONCLUSIONS:
Ten Internet samples had bovine DNA concentrations high enough to rule out minor contamination, suggesting a cow’s milk product was added. Cow’s milk can be problematic for infants with allergy or intolerance. Because buyers cannot verify the composition of milk they purchase, all should be aware that it might be adulterated with cow’s milk. Pediatricians should be aware of the online market for human milk and the potential risks.
