Perspectives on ageing, later life and ethnicity: ageing research in ethnic minority contexts
Authors: ZUBAIR MARIA , NORRIS MERIEL
Published: April 2015

This special issue focuses broadly upon questions and themes relating to the current conceptualisations, representations and use of ‘ethnicity’ (and ethnic minority experiences) within the field of social gerontology. An important aim of this special issue is to explore and address the issue of ‘otherness’ within the predominant existing frameworks for researching those who are ageing or considered aged, compounded by the particular constructions of their ethnicity and ethnic ‘difference’. The range of theoretical, methodological and empirical papers included in this collection provide some critical insights into particular facets of the current research agendas, cultural understandings and empirical focus of ethnic minority ageing research. The main emphasis is on highlighting the ways in which ethnic cultural homogeneity and ‘otherness’ is often assumed in research involving older people from ethnic minority backgrounds, and how wider societal inequalities are concomitantly (re)produced, within (and through) research itself – for example, based on narrowly defined research agendas and questions; the assumed age and/or ethnic differences of researchersvis-à-vistheir older research participants; the workings of the formalised ethical procedures and frameworks; and the conceptual and theoretical frameworks employed in the formulation of research questions and interpretation of data. We examine and challenge here the simplistic categorisations and distinctions often made in gerontological research based around research participants' ethnicity, age and ageing and assumed cultural differences. The papers presented in this collection reveal instead the actual complexity and fluidity of these concepts as well as the cultural dynamism and diversity of experiences within ethnic groups. Through an exploration of these issues, we address some of the gaps in existing knowledge and understandings as well as contribute to the newly emerging discussions surrounding the use of particular notions of ethnicity and ethnic minority ageing as these are being employed within the field of ageing studies.

Published: April 2015

Blood and oral fluid (OF) samples were collected from 103 suspected measles cases between February and November 2010 during a nationwide measles outbreak in Zimbabwe. Siemens measles IgM enzyme immunoassay (EIA) on serum, Microimmune measles IgM capture EIA on OF, real-time haemagglutinin (H) gene PCR and nested nucleocapsid (N) gene PCR on OF were performed, confirming 75 measles cases. These samples were then used to evaluate a newly developed point of care test (POCT) for measles and determine its potential for identifying measles cases in outbreaks. After performing POCTs on OF samples, nucleic acid was extracted from the used test strips and the measles H and N genes amplified by RT–PCR. The sensitivity, specificity, positive and negative predictive values of the POCT for IgM in OF was 75·0% [95% confidence interval (CI) 63·4–84·5], 96·2% (95% CI 80·4–99·9), 98·2% (95% CI 90·3–100) and 58·1% (95% CI 42·1–73·0), respectively. The N gene sequences showed high level of agreement between original OF and corresponding POCT strips. Measles genotype B3 was identified in all cases. We conclude that the measles POCT has the potential to be used, at the point of contact, in outbreak situations and provide molecular characterization of the virus at a later date.
Determination of cut-off cycle threshold values in routine RT–PCR assays to assist differential diagnosis of norovirus in children hospitalized for acute gastroenteritis

Published: April 2015

Norovirus (NV) is an important cause of acute gastroenteritis in children, but is also frequently detected in asymptomatic children, which complicates the interpretation of NV detection results in both the clinical setting and population prevalence studies. A total of 807 faecal samples from children aged <5 years hospitalized for acute gastroenteritis were collected in Thai Binh, Vietnam, from January 2011 to September 2012. Real-time RT–PCR was used to detect and quantify NV-RNA in clinical samples. A bimodal distribution of cycle threshold (Ct) values was observed in which the lower peak was assumed to represent cases for which NV was the causal agent of diarrhoea, whereas the higher peak was assumed to represent cases involving an alternative pathogen other than NV. Under these assumptions, we applied finite-mixture modelling to estimate a threshold of Ct<21·36 (95% confidence interval 20·29–22·46) to distinguish NV-positive patients for which NV was the likely cause of diarrhoea. We evaluated the validity of the threshold through comparisons with NV antigen ELISA results, and comparisons of Ctvalues in patients co-infected with rotavirus. We conclude that the use of an appropriate cut-off value in the interpretation of NV real-time RT–PCR results may improve differential diagnosis of enteric infections, and could contribute to improved estimates of the burden of NV disease.
Risk prediction tools for older general surgical patients
Authors: Middleton M , Stechman MJ , Moug S , McCarthy K , Hewitt J
Published: April 2015

This review identifies and examines the clinical application of risk prediction tools, including the American Society of Anaesthesiology (ASA) Classification System and POSSUM-based scores, in the older general surgical patient. Predicting outcomes in this patient group remains difficult; it is challenging to design a risk prediction tool that will apply to both emergency and elective surgery and that remains valid across the wide age range that this patient group encompasses. Risk prediction tools can have benefit but should be used in conjunction with the clinical assessment of those experienced in the care of this challenging patient group.
The Cold War and Socialist Identity: The Socialist International and the Italian ‘Communist Question’ in the 1970s
Authors: DI DONATO MICHELE
Published: April 2015

Coming about in a phase of renewal and electoral success for the European socialist parties, the rise of the Italian Communist Party in the 1970s elicited differentiated reactions within the Socialist International. While providing an account of the transnational socialist debate on Italian Eurocommunism, this article suggests to understand it in the context of a wider discussion on the political identity and aims of the European left. Divisions on the new ‘communist question’ amongst the socialist movement mirrored the divergent opinions on how to react to the changes that were taking place in European economics and society, as well as in the international system.
Religious Regimes: Rethinking the Societal Role of Religion in Post-War Europe
Authors: VAN DAM PETER , VAN TRIGT PAUL
Published: April 2015

This article discusses the concept of ‘religious regimes’ in order to identify institutionalised arrangements regulating the social position of religion. By analysing such regimes and the views underpinning them, three visions of the societal role of religion come into focus: segmented pluralism, the Christian nation and the secular nation. Taking up Dutch post-war history as a case study, it becomes clear that religious regimes regularly result from fragile compromises. The concept thus yields insight into the gradual transitions between different institutional arrangements regarding religion and into the impact of changing views on the societal role of religion within and outside religious communities.
The European Community's Public Communication Policy 1951–1967
Authors: HARRISON JACKIE , PUKALLUS STEFANIE
Published: April 2015

From its inception the European Community had a civil aim: the need to stimulate a European civil consciousness. Viewed as a pre-condition for the popular acceptance of increased European integration, this provided the rationale for the Community's public communication policy of 1951–1967. The Community pursued this civil aim through two distinct public communication approaches: popularist (1951–1962) and opinion leader led (1963–1967). We contend that the way the Community undertook its public communication policy cannot be understood without considering the Community's civil aim. This leads us to question some of the common views held concerning the significance of European public communication policy from 1951 to 1967.1
The Italians and Fascism
Authors: ALBANESE GIULIA
Published: April 2015

In a recent review of Christopher Duggan's latest book, Emilio Gentile notes that in the 1970s an ‘intimate history of fascist Italy’ would have met the opposition of ‘militant anti-fascist historiography’ because of its proneness to acknowledge the involvement of Italians in Fascism. Still, after criticising the book, Gentile stresses that the ‘question of consent’ – a topic on which he himself has provided some crucial contributions – is a ‘poorly posed question’.

This paper is the first record of the aforementioned anomaly for the species from the Brazilian coastline.
Upon Further Reflection—The Affinity of Noam Chomsky and B. F. Skinner
Authors: Goddard Murray J.
Published: April 2015

Comparisons between Noam Chomsky and B. F. Skinner show several striking affinities with respect to their biographical history, academic roots, apprehensions about capitalism and the media, and their social activism. In addition to outlining these points of correspondence, the present paper discusses the Chomsky-Skinner language debate by focusing on the integrative possibilities of the 2 approaches. Overall, Chomsky and Skinner may have had worldviews that were more compatible than incompatible.
Direct electron injection into an oxide insulator using a cathode buffer layer
Authors: Lee Eungkyu , Lee Jinwon , Kim Ji-Hoon , Lim Keon-Hee , Seok Byun Jun , Ko Jieun , Dong Kim Young , Park Yongsup , Kim Youn Sang
Published: April 2015

Injecting charge carriers into the mobile bands of an inorganic oxide insulator (for example, SiO2, HfO2) is a highly complicated task, or even impossible without external energy sources such as photons. This is because oxide insulators exhibit very low electron affinity and high ionization energy levels. Here we show that a ZnO layer acting as a cathode buffer layer permits direct electron injection into the conduction bands of various oxide insulators (for example, SiO2, Ta2O5, HfO2, Al2O3) from a metal cathode. Studies of current–voltage characteristics reveal that the current ohmically passes through the ZnO/oxide-insulator interface. Our findings suggests that the oxide insulators could be used for simply fabricated, transparent and highly stable electronic valves. With this strategy, we demonstrate an electrostatic discharging diode that uses 100-nm SiO2 as an active layer exhibiting an on/off ratio of ∼107, and protects the ZnO thin-film transistors from high electrical stresses.

Published: April 2015

In order to map global disease risk, a geographic database of human Crimean-Congo haemorrhagic fever virus (CCHFV) occurrence was produced by surveying peer-reviewed literature and case reports, as well as informal online sources. Here we present this database, comprising occurrence data linked to geographic point or polygon locations dating from 1953 to 2013. We fully describe all data collection, geo-positioning, database management and quality-control procedures. This is the most comprehensive database of confirmed CCHF occurrence in humans to-date, containing 1,721 geo-positioned occurrences in total.
Non-equilibrium scale invariance and shortcuts to adiabaticity in a one-dimensional Bose gas
Authors: Rohringer W. , Fischer D. , Steiner F. , Mazets I. E. , Schmiedmayer J. , Trupke M.
Published: April 2015

We present experimental evidence for scale invariant behaviour of the excitation spectrum in phase-fluctuating quasi-1d Bose gases after a rapid change of the external trapping potential. Probing density correlations in free expansion, we find that the temperature of an initial thermal state scales with the spatial extension of the cloud as predicted by a model based on adiabatic rescaling of initial eigenmodes with conserved quasiparticle occupation numbers. Based on this result, we demonstrate that shortcuts to adiabaticity for the rapid expansion or compression of the gas do not induce additional heating.

Cadmium toxicity induces ER stress and apoptosis via impairing energy homoeostasis in cardiomyocytes
Authors: Chen Chun-yan , Zhang Shao-li , Liu Zhi-yong , Tian Yong , Sun Qian
Published: April 2015

Cadmium, a highly toxic environmental pollutant, is reported to induce toxicity and apoptosis in multiple organs and cells, all possibly contributing to apoptosis in certain pathophysiologic situations. Previous studies have described that cadmium toxicity induces biochemical and physiological changes in the heart and finally leads to cardiac dysfunctions, such as decreasing contractile tension, rate of tension development, heart rate, coronary flow rate and atrioventricular node conductivity. Although many progresses have been made, the mechanism responsible for cadmium-induced cellular alternations and cardiac toxicity is still not fully understood. In the present study, we demonstrated that cadmium toxicity induced dramatic endoplasmic reticulum (ER) stress and impaired energy homoeostasis in cultured cardiomyocytes. Moreover, cadmium toxicity may inhibit protein kinase B (AKT)/mTOR (mammalian target of rapamycin) pathway to reduce energy productions, by either disrupting the glucose metabolism or inhibiting mitochondrial respiratory gene expressions. Our work will help to reveal a novel mechanism to clarify the role of cadmium toxicity to cardiomyocytes and provide new possibilities for the treatment of cardiovascular diseases related to cadmium toxicity.
Modelling of the impedance frequency response of transformers at no load and under nominal conditions
Authors: Januário Marconi , Kuo‐Peng Patrick , Batistela Nelson Jhoe
Published: April 2015

The need for models that represent the behaviour of transformers operating in steady state or submitted to transient events is of great importance in studies involving power systems. In this context, this study presents a model used to represent the impedance frequency response of transformers at no load and under nominal conditions. In the model, networks of parameters with RLC cells are employed to reproduce the resonances present in the frequency responses and also RL network sections are used to represent the frequency‐dependent effects in the core, which aid in the current damping during transient events. The parameter values of these networks are determined with the least‐squares numerical method. To evaluate the model as well as the methodology to determine the parameter values, data originating from measurements of the frequency responses with frequency range from 10 Hz to 2 MHz of two single‐phase transformers (16 kVA and 55 MVA) are used. Validations of the model are carried out in the frequency and time domains. The model can be used to simulate transformer operation under nominal conditions of voltage and frequency and also for a broad frequency spectrum.
Relay logic for islanding detection in active distribution systems
Authors: Vatani Mehrnoosh , Amraee Turaj , Ranjbar Ali Mohammad , Mozafari Babak
Published: April 2015

This study presents a passive model to detect islanding conditions of synchronous distributed generation resources in a distribution network or a microgrid. The proposed approach uses the classification and regression tree algorithm for distinguishing between islanding and non‐islanding situations. It utilises the rate of change of frequency (ROCOF) and harmonic content of the equivalent reactance seen at the location of distributed generation as input features for decision tree construction. Indeed the thresholds of the proposed input features are extracted by the decision tree algorithm. The output if‐then rules of the decision tree algorithm are then utilised to make a new relay logic for islanding detection. The proposed scheme successfully classifies the input data with approximately zero non‐detection zone and prevent false operation of traditional scheme. The performance of the proposed protective algorithm is compared with the traditional ROCOF relay, artificial neural network and support vector machine techniques. The proposed method is implemented in a typical microgrid, which is connected to the transmission network of the dynamic WSCC three‐machine, 9bus test system with considering electric faults at upstream transmission and sub‐transmission networks.
Three‐mode pulse‐width modulation of a three‐phase four‐wire inverter
Authors: Li Xiangfeng , Zhang Bo , Qiu Dongyuan
Published: April 2015

In order to reduce the switching frequencies of power semiconductors and then to increase the efficiency in a three‐phase four‐wire inverter, the state controllability of a system is investigated by considering the inverter as a switched linear system. It is found that a three‐phase four‐wire inverter is a three‐mode controllable, therein, only three non‐zero vectors are required to make the system completely state controllable. With the three operating modes, a novel control strategy, called a three‐mode pulse‐width modulation (3‐MPWM), is proposed in this study. There are three types of 3‐MPWMs, that is, 3‐MPWM(I), 3‐MPWM(II) and 3‐MPWM(III). Compared with the conventional space‐vector pulse width modulation strategy, the switching frequencies of the proposed 3‐MPWMs are significantly reduced by two‐thirds, hence, the switching losses of the power semiconductors can be reduced and the efficiency of the inverter can be improved. In addition, the number of operating modes used in 3‐MPWM(I) and 3‐MPWM(II) is reduced by a half. Finally, simulation and experimental results are conducted to verify the effectiveness of the 3‐MPWM strategies.
Experimental investigation of thermal conductivity of medical nanofluids based on functionalised single‐wall carbon nanotube and conjugated cisplatin
Authors: Kazemi‐Beydokhti Amin , Zeinali Heris S. , Jaafari M.R.
Published: April 2015

Thermal engineering parameters such as thermal conductivity (TC) can play an important role in developing medical nanofluids with improved stability and better drug release. In this reported work, an engineering perspective is strategised for the development of medical nanofluids containing functionalised single‐wall carbon nanotubes and conjugated cisplatin. These nanofluids were developed by two biocompatible phospholipids. For the first time, the change in TC values of this medical nanofluid was investigated. The change in the drug release was examined before and after dialysis with change in pH and temperature, in vitro. It was found that an increase in temperature leads to higher TC and a decrease in pH provides better thermophysical conditions for the drug release. These findings strongly suggest that TC could be an important parameter in the development of medical nanofluids for cancer treatment.

Authors: Zhong Yaping , Deng Chun , He Yu , Ge Yili , Song Gongwu
Published: April 2015

Hexamethylene‐1,3‐bis(cetyldimethylammonium bromide) (G16‐6‐16) protected low‐toxicity ZnSe quantum dots (QDs) were successfully synthesised and used as fluorescence probe to detect proteins such as bovine serum albumin (BSA). This method is simple, fast, selective and sensitive. Surfactant G16‐6‐16 can interact with proteins through hydrophobic effect, thus leading to the fluorescence quenching of G16‐6‐16 protected ZnSe QDs nanometre material. The fluorescence intensity of G16‐6‐16 protected ZnSe QDs was linearly proportional to BSA over a concentration range from 0 to 80 nM with a correlation coefficient of 0.993. The detection limit was 0.04 nM. This method was successfully applied to determine BSA in urine samples which shows the good application value of this nanometre material.
The ensemble switch method for computing interfacial tensions
Authors: Schmitz Fabian , Virnau Peter
Published: April 2015

We present a systematic thermodynamic integration approach to compute interfacial tensions for solid-liquid interfaces, which is based on the ensemble switch method. Applying Monte Carlo simulations and finite-size scaling techniques, we obtain results for hard spheres, which are in agreement with previous computations. The case of solid-liquid interfaces in a variant of the effective Asakura-Oosawa model and of liquid-vapor interfaces in the Lennard-Jones model are discussed as well. We demonstrate that a thorough finite-size analysis of the simulation data is required to obtain precise results for the interfacial tension.
Energy dynamics and current sheet structure in fluid and kinetic simulations of decaying magnetohydrodynamic turbulence

Published: April 2015

Simulations of decaying magnetohydrodynamic (MHD) turbulence are performed with a fluid and a kinetic code. The initial condition is an ensemble of long-wavelength, counter-propagating, shear-Alfvén waves, which interact and rapidly generate strong MHD turbulence. The total energy is conserved and the rate of turbulent energy decay is very similar in both codes, although the fluid code has numerical dissipation, whereas the kinetic code has kinetic dissipation. The inertial range power spectrum index is similar in both the codes. The fluid code shows a perpendicular wavenumber spectral slope of k⊥−1.3. The kinetic code shows a spectral slope of k⊥−1.5 for smaller simulation domain, and k⊥−1.3 for larger domain. We estimate that collisionless damping mechanisms in the kinetic code can account for the dissipation of the observed nonlinear energy cascade. Current sheets are geometrically characterized. Their lengths and widths are in good agreement between the two codes. The length scales linearly with the driving scale of the turbulence. In the fluid code, their thickness is determined by the grid resolution as there is no explicit diffusivity. In the kinetic code, their thickness is very close to the skin-depth, irrespective of the grid resolution. This work shows that kinetic codes can reproduce the MHD inertial range dynamics at large scales, while at the same time capturing important kinetic physics at small scales.

Published: April 2015

The thermodynamics and kinetics of the one dimensional lattice gas with repulsive interaction are investigated using transfer matrix technique and Monte Carlo simulations. This simple model is shown to exhibit waterlike anomalies in density, thermal expansion coefficient, and self-diffusion. An unified description for the thermodynamic anomalies in this model is achieved based on the ground state residual entropy which appears in the model due to mixing entropy in a ground state phase transition.
