Contact, Cigarette and Flame Burns in Physical Abuse: A Systematic Review
Authors: Kemp Alison M. , Maguire Sabine A. , Lumb Rebecca C. , Harris Stacey M. , Mann Mala K. 
Published: June 2013

This systematic review identifies features of intentional non‐scald burns in physical abuse. Fifteen bibliographic databases of international literature (1950–2011) were searched to identify potential studies that were critically appraised using standardised methods. Primary studies with confirmed intentional non‐scald burns in children aged < 18 years were included to provide a descriptive analysis of the causation, appearance and distribution of burns.‘This systematic review identifies features of intentional non‐scald burns in physical abuse’Twenty studies were included: one cross‐sectional, one case control and 18 case studies/small case series representing 73 children with intentional non‐scald burns. The majority were contact burns from household items: the agents included cigarettes (18), irons (9), electric fires/heaters/radiators (10), cigarette lighters (2), hairdryers (7), curling tongs (3), chemicals (3), microwaves (2) flame burns (7), miscellaneous (7) and burns of unknown cause (5). The burns occurred throughout childhood. The majority of children were older than three years. The characteristic features were of clearly demarcated contact burns or scars in shapes that mirrored the agent. They were predominantly recorded on the limbs, trunks and the backs of hands; they were frequently multiple and co‐existed with additional signs of abuse. These features should raise concerns of suspected physical abuse. Copyright © 2013 John Wiley & Sons, Ltd.Key Practitioner MessagesIntentional Non‐scald Burns

The commonest reported cause of intentional non‐scald burns are contact burns: cigarettes, irons, hairdryers or domestic heaters.
Burns are often clearly demarcated in the shape of the causative agent.
Burns are found on the limbs, back or trunk, in locations other than the palms of the hands.
Burns are often multiple and may co‐exist with other injuries suspicious of abuse.
Single or multiple circular, deep‐cratered burns are consistent with cigarette burns.‘The commonest reported cause of intentional non‐scald burns are contact burns’
Disentangling the influence of attachment anxiety and attachment security in consumer formation of attachments to brands
Authors: Proksch Michael , Orth Ulrich R. , Bethge Franziska 
Published: June 2013

ABSTRACTThis research investigates the formation of consumer attachments to brands contingent upon their attachment anxiety and security. An experiment utilizes a consumer sample and real brands across four product categories (apparel, body care, consumer electronics, and soft drinks) to test the relations between consumer–brand identification and brand attachment dependent on attachment anxiety and attachment security. Consistent with previous research, the findings initially confirm that consumer–brand identification relates positively to brand attachment. Prior work is extended, however, by demonstrating that attachment anxiety has a strong influence on this relationship by moderating the effect of consumer–brand identification on brand attachment but only under low attachment security and with women. Implications relate to attachment research and brand management. Copyright © 2013 John Wiley & Sons, Ltd.
Acid–Base‐Controlled Stereoselective Metalation of Overhanging Carboxylic Acid Porphyrins: Consequences for the Formation of Heterobimetallic Complexes

Published: June 2013

AbstractOverhanging carboxylic acid porphyrins have revealed promising ditopic ligands offering a new entry in the field of supramolecular coordination chemistry of porphyrinoids. Notably, the adjunction of a so‐called hanging‐atop (HAT) PbII cation to regular PbII porphyrin complexes allowed a stereoselective incorporation of the N‐core bound cation, and an allosterically controlled Newton’s cradle‐like motion of the two PbII ions also emerged from such bimetallic complexes. In this contribution, we have extended this work to other ligands and metal ions, aiming at understanding the parameters that control the HAT PbII coordination. The nature of the N‐core bound metal ion (ZnII, CdII), the influence of the deprotonation state of the overhanging COOH group and the presence of a neutral ligand on the opposite side (exogenous or intramolecular), have been examined through 1H NMR spectroscopic experiments with the help of radiocrystallographic structures and DFT calculations. Single and bis‐strap ligands have been considered. They all incorporate a COOH group hung over the N‐core on one side. For the bis‐strap ligands, either an ester or an amide group has been introduced on the other side. In the presence of a base, the mononuclear ZnII or CdII complexes incorporate the carbonyl of the overhanging carboxylate as apical ligand, decreasing its availability for the binding of a HAT PbII. An allosteric effector (e.g., 4‐dimethylaminopyridine (DMAP), in the case of a single‐strap ligand) or an intramolecular ligand (e.g., an amide group), strong enough to compete with the carbonyl of the hung COO−, is required to switch the N‐core bound cation to the opposite side with concomitant release of the COO−, thereby allowing HAT PbII complexation. In the absence of a base, ZnII or CdII binds preferentially the carbonyl of the intramolecular ester or amide groups in apical position rather than that of the COOH. This better preorganization, with the overhanging COOH fully available, is responsible for a stronger binding of the HAT PbII. Thus, either allosteric or acid–base control is achieved through stereoselective metalation of ZnII or CdII. In the latter case, according to the deprotonation state of the COOH group, the best electron‐donating ligand is located on one or the other side of the porphyrin (COO−>CONHR>COOR>COOH): the lower affinity of COOH for ZnII and CdII, the higher for a HAT PbII. These insights provide new opportunities for the elaboration of innovative bimetallic molecular switches.

AbstractGlycolysis lies at the basis of metabolism and cell energy supply. The disregulation of glycolysis is involved in such pathological processes as cancer proliferation, neurodegenerative diseases, and amplification of ischemic damage. Phosphofructokinase‐2 (PFK‐2), a bifunctional enzyme and regulator of glycolytic flux, has recently emerged as a promising anticancer target. Herein, the computer‐aided design of a new class of aminofurazan‐triazole regulators of PFK‐2 is described along with the results of their in vitro evaluation. The aminofurazan‐triazoles differ from other recently described inhibitors of PFK‐2 and demonstrate the ability to modulate glycolytic flux in rat muscle lysate, producing a twofold decrease by inhibitors and fourfold increase by activators. The most potent compounds in the series were shown to inhibit the kinase activity of the hypoxia‐inducible form of PFK‐2, PFKFB3, as well as proliferation of HeLa, lung adenocarcinoma, colon adenocarcinoma, and breast cancer cells at concentrations in the low micromolar range.
Role of contextual properties in enterprise service migration to cloud computing
Authors: Khan Khaled M. , Malluhi Qutaibah 
Published: June 2013

SUMMARYThis paper attempts to identify the role of contextual properties of enterprise systems architecture in relation to service migration to cloud computing. In a cloud‐based service architecture, the shift of ownership, scope, and control over architectural elements from consumers to cloud providers has a profound impact on ways cloud consumers design and manage their systems architecture. In this perspective, we introduce the concepts of architectural scope, ownership, and control as the contextual properties of systems architecture. The paper explores ways in which these properties can be mapped into a quantifiable framework that could be used to measure the degree of changes of contextual properties due to service migration to cloud computing. We seek here to address the service migration problems from a different perspective, namely, focusing on the contextual properties of architectural elements. Copyright © 2013 John Wiley & Sons, Ltd.

Published: June 2013

ABSTRACTThe purpose of this paper is to explore the evolution of the concept of corporate social responsibility (CSR) in academia. The process of evolution is conceptualised to consist of diffusion and dynamics. Bibliometrics were applied for data collection and visualisation of the evolution of CSR. The findings show increasing complexity and progression in the research on the concept of CSR fuelled not only by the efforts for intellectual refinement in the field but also reflecting the changing priorities of society and businesses. The growth of this field of research both in number of publications (i.e. diffusion) and in terms of different fields in academic usage (i.e. dynamics), is an indicator for growing complexity and widening acceptance of the CSR concept across various academic disciplines in the future.

Multichannel cooperative sensing for cognitive radio with users owning heterogeneous sensing ability
Authors: Ge Wendong , Ji Hong , Li Xi 
Published: June 2013

SUMMARYMultichannel cooperative sensing (MCS) is an effective method for dynamic spectrum access in cognitive radio networks. In contrast to most existing work on MCS that considered secondary users with homogeneous sensing ability, this paper studies the MCS problem for secondary users with heterogeneous sensing ability in terms of sensing accuracy. We further take into account different parameters of primary channels such as bandwidth, probability of being idle in each sensing period, and frequency selective fading at the sensing receiver. The MCS problem is formulated as a weapon target assignment problem, where more sensing resources are assigned to channels that are more valuable. This weapon target assignment problem is transformed to an integer generalized network flow problem with convex flow costs to obtain the lower bound solution, and then solved by the branch and bound algorithm with this bound to yield the exact scheme. To reduce computational complexity, a heuristic scheme is also proposed, which has approximate performance compared with the exact scheme. Finally, extensive simulation results for different scenarios illustrate the performance improvements of the proposed schemes over the existing scheme. Copyright © 2013 John Wiley & Sons, Ltd.
Combining molecular evolution and environmental genomics to unravel adaptive processes of MHC class IIB diversity in European minnows (Phoxinus phoxinus)

Published: June 2013

AbstractHost–pathogen interactions are a major evolutionary force promoting local adaptation. Genes of the major histocompatibility complex (MHC) represent unique candidates to investigate evolutionary processes driving local adaptation to parasite communities. The present study aimed at identifying the relative roles of neutral and adaptive processes driving the evolution of MHC class IIB (MHCIIB) genes in natural populations of European minnows (Phoxinus phoxinus). To this end, we isolated and genotyped exon 2 of two MHCIIB gene duplicates (DAB1 and DAB3) and 1′665 amplified fragment length polymorphism (AFLP) markers in nine populations, and characterized local bacterial communities by 16S rDNA barcoding using 454 amplicon sequencing. Both MHCIIB loci exhibited signs of historical balancing selection. Whereas genetic differentiation exceeded that of neutral markers at both loci, the populations' genetic diversities were positively correlated with local pathogen diversities only at DAB3. Overall, our results suggest pathogen‐mediated local adaptation in European minnows at both MHCIIB loci. While at DAB1 selection appears to favor different alleles among populations, this is only partially the case in DAB3, which appears to be locally adapted to pathogen communities in terms of genetic diversity. These results provide new insights into the importance of host–pathogen interactions in driving local adaptation in the European minnow, and highlight that the importance of adaptive processes driving MHCIIB gene evolution may differ among duplicates within species, presumably as a consequence of alternative selective regimes or different genomic context.
G‐Quadruplex‐Linked Supersandwich DNA Structure for Electrochemical Amplified Detection of Thrombin
Authors: Wang Guangfeng , He Xiuping , Zhu Yanhong , Chen Ling , Wang Lun , Zhang Xiaojun 
Published: June 2013

AbstractIn this paper, a novel strategy of electrochemical amplified detection of thrombin based on G‐quadruplex‐linked supersandwich structure was described. In the presence of K+ and hemin, the original hairpin DNA sequence activated an autonomous cross‐opening process to build up hemin/G‐quadruplex structure and can hybridize to form supersandwich structure containing multiple signal labels. With the addition of thrombin, it conjugated with its aptamer, leading to a remarkably descended signal. The supersandwich‐amplified electrochemical sensor system was highly sensitive in the concentration range from 10−6 to 10−10 M with a detection limit of 10 pM and also demonstrated excellent selectivity. The amplifying supersandwich structure with multiple labels can be implemented as a versatile sensing platform for analyzing other DNA in the presence of the appropriate probe.
EFMP – a new congestion control mechanism for flow‐aware networks
Authors: Domżał Jerzy , Wójcik Robert , López Victor , Aracil Javier , Jajszczyk Andrzej 
Published: June 2013

ABSTRACTIn this paper, a new congestion control mechanism for flow‐aware networks, that is, enhanced flushing mechanism with priority (EFMP) is introduced. Proposed by J. Roberts and S. Oueslati in 2004, flow‐aware networking is a concept that ensures quality of service in networks based on flows. EFMP improves the efficiency of transmission in FAN by introducing new policies in the admission control block of a cross‐protect router. The mechanism is thoroughly described, analysed, and validated through simulations. The proposed mechanism inherits the advantages of previously known admission control schemes while ensuring fast acceptance times of new streaming flows and proper transmission of the remaining traffic. Moreover, the comparison with the multilayer flow‐aware networks architecture shows that EFMP ensures better performance and lower cost of transmission in a network with limited resources.

Joint optimisation algorithm of cooperative spectrum sensing with cooperative overhead and sub‐band transmission power for wideband cognitive radio network
Authors: Liu Xin , Bi Guoan , Guan Yong Liang , Lu Weidang , Yan Junhua , Zhong Weizhi 
Published: June 2013

AbstractCognitive radio (CR) allows a secondary user (SU) to utilise the spectrum allocated to the primary user (PU) on the premise of detecting the absence of PU by spectrum sensing. The SU often adopts cooperative spectrum sensing to cope with the hidden terminal problem if the PU is shadowed or in serious multi‐path fading; however, the cooperative overhead may decrease the throughput of the SU. In this paper, we consider a wideband CR network that can reuse multiple idle sub‐bands after cooperative spectrum sensing and then analyse the total throughput of the SU over all the sub‐bands. A multi‐variable nonconvex optimisation problem of cooperative spectrum sensing with cooperative overhead and sub‐band transmission power is proposed, which maximises the total throughput of the SU subject to the constraints of the false‐alarm probability, the detection probability, the cooperative overhead and the maximal total power of the SU. For obtaining the optimal solution, we divide the optimisation problem into two sub‐optimisation problems: one for optimising the cooperative spectrum sensing including the sensing time and the number of SUs and the other one for optimising the sub‐band transmission power. We have proven the convex optimisation of the two sub‐optimisation problems and proposed a joint optimisation algorithm of the sensing time, the number of SUs and the sub‐band transmission power. The simulation results show that the proposed joint optimisation algorithm can achieve the largest throughput with the false‐alarm probability and the detection probability within their limits.

Dynamic semantic‐based adaptation of multimedia documents
Authors: Alti Adel , Laborie Sébastien , Phillipe Roose 
Published: June 2013

ABSTRACTOne of the key aspects of any mobile multimedia application is the management of multimedia documents. Currently, multimedia documents can be displayed on multiple platforms (laptops, smartphones, tablets, etc.) that result in a birth of new information system called pervasive. The various execution contexts of a multimedia presentation introduce different constraints for the presentation itself. This includes device constraints and user preferences, resulting to the overall system heterogeneity increase. In this paper, we propose a specific ontology for on‐the‐fly (at runtime) adaptation of multimedia documents. Thus, we propose rules allowing automatic generation of dynamic and quality assembly of heterogeneous components. The proposed ontology has the great advantage to offer a flexible infrastructure to users to easily govern the response time and the quality assembly of their own applications at runtime.

Expiration‐Day Effects and the Impact of Short Trading Breaks on Intraday Volatility: Evidence from the Indian Market
Authors: Agarwalla Sobhesh Kumar , Pandey Ajay 
Published: June 2013

AbstractOne distinct feature of the Indian stock market is the large trading volume of single stock futures, which are cash settled on the basis of the volume‐weighted average spot prices of the underlying stocks during the last half‐an‐hour of trading on the expiration day. We investigate the expiration day effect on intraday volatility and find that the volatility of the stocks increases in the last half‐an‐hour trade on the expiry day but not during the other time intervals. We also investigate the volatility surrounding the intraday trading breaks induced by satellite communication outages, a peculiar feature of the Indian stock market till 2008, and find that the volatility rises when the market reopens after the breaks but not before the breaks. © 2013 Wiley Periodicals, Inc.

Published: June 2013

AbstractBiological productivity is a key factor controlling the ocean's ability to take up carbon dioxide from the atmosphere. However, the ecological dynamics that drive regions of intense productivity and carbon export are poorly understood. In this study, we present high‐spatial‐resolution estimates of air‐sea CO2 flux, net community production (NCP) rates calculated from O2/Ar ratios, and phytoplankton population abundances determined by continuous underway measurements on a cruise across the Gulf of Alaska in May 2010. The highest rates of NCP (79.2 ± 13 mmol C m‐2 d‐1) and oceanic CO2 uptake (air‐sea flux of −14.7 ± 2.4 mmol C m‐2 d‐1) were observed across a transition zone between the high‐nitrate low‐chlorophyll (HNLC) waters of the Alaskan Gyre and the coastal waters off the Aleutian Islands. While the transition zone comprises 20% of the total area covered in crossing the Gulf of Alaska, it contributed 49% of the total NCP and 48% of the total CO2 uptake observed along the cruise track. A corresponding transition zone phytoplankton bloom was dominated by two small‐celled (<20 µm) phytoplankton communities, which were distinct from the phytoplankton communities in the surrounding Alaskan Gyre and coastal waters. We hypothesize that mixing between iron‐rich coastal waters and iron‐limited Alaskan Gyre waters stimulated this bloom and fueled the high NCP and CO2 export observed in the region.
HEALTH INSURANCE TAX CREDITS, THE EARNED INCOME TAX CREDIT, AND HEALTH INSURANCE COVERAGE OF SINGLE MOTHERS
Authors: Cebi Merve , Woodbury Stephen A. 
Published: June 2013

SUMMARYThe Omnibus Budget Reconciliation Act of 1990 enacted a refundable tax credit for low‐income working families who purchased health insurance coverage for their children. This health insurance tax credit (HITC) existed during tax years 1991, 1992, and 1993, and was then rescinded. A difference‐in‐differences estimator applied to Current Population Survey data suggests that adoption of the HITC, along with accompanying increases in the Earned Income Tax Credit (EITC), was associated with a relative increase of about 4.7 percentage points in the private health insurance coverage of working single mothers with high school or less education. Also, a difference‐in‐difference‐in‐differences estimator, which attempts to net out the possible influence of the EITC increases but which requires strong assumptions, suggests that the HITC was responsible for about three‐quarters (3.6 percentage points) of the total increase. The latter estimate implies a price elasticity of health insurance take‐up of −0.42. Copyright © 2013 John Wiley & Sons, Ltd.
THE IMPACT OF SOCIAL HOUSING ON THE LABOUR MARKET STATUS OF THE DISABLED
Authors: Gregoir Stéphane , Maury Tristan‐Pierre 
Published: June 2013

ABSTRACTDisability may impact on employment through entitlement to social housing. Estimates of an original dynamic panel data model of disability, labour market and housing tenure transitions in England indicate that up to one‐quarter of the lower employment probability of the disabled can be attributed to the effect of qualifying for social housing. Short‐lived disabilities can result in long spells in social housing that reduce incentives to participate in the labour market. This suggests that authorities should reform the welfare system and the allocation of social housing to limit the persistent and unfavourable consequences of allocating social housing to the disabled.
