A tutorial introduction to the statistical theory of turbulent plasmas, a half-century after Kadomtsev’sPlasma Turbulenceand the resonance-broadening theory of Dupree and Weinstock
Authors: Krommes John A. 
Published: September 2015

In honour of the 50th anniversary of the influential review/monograph on plasma turbulence by B. B. Kadomtsev as well as the seminal works of T. H. Dupree and J. Weinstock on resonance-broadening theory, an introductory tutorial is given about some highlights of the statistical–dynamical description of turbulent plasmas and fluids, including the ideas of nonlinear incoherent noise, coherent damping, and self-consistent dielectric response. The statistical closure problem is introduced. Incoherent noise and coherent damping are illustrated with a solvable model of passive advection. Self-consistency introduces turbulent polarization effects that are described by the dielectric function${\mathcal{D}}$. Dupree’s method of using${\mathcal{D}}$to estimate the saturation level of turbulence is described; then it is explained why a more complete theory that includes nonlinear noise is required. The general theory is best formulated in terms of Dyson equations for the covariance$C$and an infinitesimal response function$R$, which subsumes${\mathcal{D}}$. An important example is the direct-interaction approximation (DIA). It is shown how to use Novikov’s theorem to develop an$\boldsymbol{x}$-space approach to the DIA that is complementary to the original$\boldsymbol{k}$-space approach of Kraichnan. A dielectric function is defined for arbitrary quadratically nonlinear systems, including the Navier–Stokes equation, and an algorithm for determining the form of${\mathcal{D}}$in the DIA is sketched. The independent insights of Kadomtsev and Kraichnan about the problem of the DIA with random Galilean invariance are described. The mixing-length formula for drift-wave saturation is discussed in the context of closures that include nonlinear noise (shielded by${\mathcal{D}}$). The role of$R$in the calculation of the symmetry-breaking (zonostrophic) instability of homogeneous turbulence to the generation of inhomogeneous mean flows is addressed. The second-order cumulant expansion and the stochastic structural stability theory are also discussed in that context. Various historical research threads are mentioned and representative entry points to the literature are given. Some outstanding conceptual issues are enumerated.
Do social values influence levels of conservation effort in threatened species? The case of two Australian chats
Authors: Ainsworth Gillian B. , Aslin Heather J. , Weston Michael A. , Garnett Stephen T. 
Published: September 2015

AbstractThis research aims to understand why one of two almost identical subspecies of the Australian yellow chat Ephthianura crocea has received significantly higher levels of local and institutional support than the other despite both having the same conservation status and taxonomic distinctiveness, factors commonly thought to influence conservation effort. Using a qualitative multiple case study approach we explored how a range of social factors, including stakeholder attitudes and institutional, policy and operational aspects, might have affected conservation efforts for the two taxa. Our results suggest that the conservation trajectories of these two subspecies have diverged since their identification as threatened species in 2000 because of differences in the social landscapes within which they persist. For one subspecies local advocacy was kindled initially by the small number of local endemic bird species but developed into a strong emotional engagement, resulting in increased local awareness, government funding, and effectiveness of conservation action. The other subspecies has had to compete for attention with approximately 200 other threatened taxa occurring in its region. No individual advocate has accorded this subspecies a high priority for action, and none of those responsible for its conservation have seen it or acknowledged an emotional attachment to it. Our findings confirm that initiation of conservation effort is strongly tied to the social values of individuals with power to take action, regardless of legislation.
Historicising Eurocentrism and anti-Eurocentrism in IR: A revisionist account of disciplinary self-reflexivity
Authors: KURU DENIZ 
Published: September 2015

AbstractThe role of Eurocentrism in International Relations (IR) has become a focal point for critical scholarship. However, anti-Eurocentric scholars tend to overlook the extent to which Eurocentrism is a tempo-spatial phenomenon whose roots and development need to be analysed in a way that takes its internal differences into account. This article rejects a single notion of Eurocentrism, proposing instead to understand Eurocentrism through its three forms: historical-contextual, ideological, and residual. This differentiation can provide a means for dealing with the challenges of Eurocentrism in a more self-reflexive manner without seeing it as omnipresent and unchanging. It also offers to approach Eurocentric IR from a perspective that considers the role of historiographical differences in understanding the rise of European powers. This means that IR cannot base its explanatory frameworks on a single (the) historical record. Understanding the limits of Eurocentrism and of anti-Eurocentrism provides a better means for dealing with the formerʼs problematic impact on IR scholarship.
Well-defined atomic hydrogen target driven by electromagnetic shock wave for stopping power measurement
Authors: Kondo Kotaro , Yokozuka Tomohiro , Oguri Yoshiyuki 
Published: September 2015

AbstractThe precise estimation of stopping power is crucial to predict the beam energy loss in the target for heavy-ion fusion and heavy-ion-driven high-energy density physics experiments. The electromagnetic shock wave has been proposed to generate a well-defined atomic hydrogen target for the stopping power measurement with dissociation effects. We measured the angular distribution profile of the discharge plasma and the plasma velocity in the electromagnetic shock tube by high-speed framing cameras. To improve the uniformity of the discharge plasma and the velocity, an external magnetic field was applied in the electromagnetic shock tube. The plasma velocity was up to approximately 40 km/s for an initial hydrogen gas pressure of 100 Pa and the velocity decreased with the initial pressure and the propagation length. The framing cameras showed that angular distributions of the discharge plasmas were not uniform and the initial angular distributions were important for the development of plasma profiles. The interaction of the plasma with the external magnetic field was estimated using the ratio of the plasma dynamic pressure to the magnetic pressure. The estimations offer more magnetic fields to improve the discharge uniformity due to the interaction.
Analysis of QTLs for the micromorphology on the seed coat surface of soybean using recombinant inbred lines
Authors: Otobe Kazunori , Watanabe Satoshi , Harada Kyuya 
Published: September 2015

AbstractThe seed coat of soybean (Glycine max (L.) Merrill) must protect the seed but allow water intake. Overprotection, causing impermeability, is assumed to be due to the presence of an impermeable layer in the seed coat, although validation of this assumption has relied on imbibition testing, which tends to be influenced by microfractures in the seed coat. Recent micromorphological analyses using laser-assisted topography microscopy revealed links to the surface roughness (SR) of the seed coat. To verify genetic links between hardseededness and SR, we analysed quantitative trait loci (QTLs) governing SR formation using 148 recombinant inbred lines (RILs) with a genetic linkage map covering 2663.6 cM of all 20 linkage groups of soybean, with 355 DNA markers and 5 phenotype markers. Five QTLs were detected, including previously identified hardseededness QTLs for ratio of seeds absorbing water, namely RAS1 and RAS2, which accounted for 20% of the phenotypic variance, and one near a locus inhibiting seed coat colour (I). These results indicate that the impermeability of soybean seed is genetically related to the reduction of SR.

Published: September 2015

AbstractIntroductionLocally advanced head and neck cancer can be a distressing disease due to a variety of reasons. This retrospective study looks at the tolerability and outcomes for palliative split-course hypofractionated radiotherapy for this group of patients treated in our centre.ResultsA total of 59 patients were treated with hypofractionated split-course radiotherapy for incurable mucosal squamous cell carcinoma of the head and neck region in our centre over a 10-year period. In all, 71% had stage IV disease. Radiotherapy consisted of three phases of 14·4 Gy/phase, in four to eight fractions over 4 days giving one·8–3·6 Gy/fraction. The phases were separated by 2 weeks. A total of 40 patients (63%) completed all three phases. A total of 72% patients had no acute toxicities and the palliation rate was 83% (complete and partial). Only five patients had no meaningful palliation having completed all three phases. Median duration of local control was 6 months (range: 1–63 months) and median overall survival was 8 months (range: 1–68 months). In five patients, the control was durable with no recurrence at the time of analysis with survival ranging from 6 to 57 months.ConclusionWe are the first UK centre to report with long-term data, the use of a palliative three phase regime that provides meaningful palliation with acceptable toxicities. In addition, for some patients, it has resulted in durable long-term control.
Proton therapy in craniospinal irradiation: a systematic review
Authors: Husak Adam I. , Bridge Pete 
Published: September 2015

AbstractAimCraniospinal irradiation is a technique indicated when a patient has a malignancy that has either disseminated, or is at risk of disseminating, throughout the subarachnoid space. While the craniospinal axis is treatable with conventional radiotherapy, the high doses to organs at risk carry an increased risk of acute and late side effects. Proton craniospinal irradiation is an expensive technique that shows great theoretical promise arising from reduced exit doses. The purpose of this systematic review is to determine the potential role of proton therapy as a standard modality for craniospinal irradiation.Materials and methodsA literature review was performed to determine the efficacy and cost of proton craniospinal irradiation. The Cochrane Library and the Inspec, Medline (via Pubmed) and Scopus databases were searched. After exclusion criteria were applied, the remaining papers were systematically appraised utilising the Scottish Intercollegiate Guidelines Network critical appraisal checklists.ResultsA total of 14 articles remained following the application of the screening and critical appraisal processes. In total, five of the articles concluded that the risk of secondary malignancy was lower with proton therapy, while ten of the articles included data showing that toxicity rates and organs at risk doses were lower with proton therapy. Doses to most thoracic and abdominal organs at risk analysed in the literature were reduced when proton therapy was used, with the sole exception of the oesophagus, the dose to which depended on whether or not the entire vertebral body was treated. Proton therapy also delivered optimal doses to organs at risk in the head and neck compared with conformal radiation therapy. However, in one study that compared tomotherapy to proton therapy, tomotherapy outperformed proton therapy by delivering lower doses to organs at risk in the head and neck, as well as the kidneys. The two cost-effectiveness studies did not indicate proton therapy as an optimal modality for all treatment sites; however, one of the studies found that for medulloblastoma, protons were more cost effective than conventional radiation therapy.FindingsProton therapy is a superior treatment option for craniospinal irradiation. The reduction in risk of toxicity and radiocarcinogenesis offered by proton craniospinal irradiation appear to outweigh the increased costs.

AimTo determine the psychometric properties of the Sympathy–Acceptance–Understanding–Caring Competence (SAUC) model questionnaire for foreign-born parents evaluating nursing encounters in the Swedish Primary Child Health Care (PCHC) services.BackgroundMulticultural encounters in child health care from the nursing perspective are challenging and problematic worldwide. A suitable theory-based and validated questionnaire is needed for foreign-born parents to assess the quality of their encounters with nurses.MethodsThe SAUC questionnaire, modified for use by new, foreign-born parents using the Swedish PCHC services, was evaluated for its congruence with the theory of Confirming Encounter. The study was ethically approved and data were collected between March and August 2009 from 83 new, foreign-born parents seen at 50 clinics.Exploratory factor analysis was used to identify related factors, and goodness-of-fit tests were used to estimate theoretical consistency. Confirmatory Factor Analysis was used to verify the results.FindingsThe questionnaire had satisfactory theoretical consistency with the theory of Confirming Encounter. Three factors identified by exploratory factor analysis and confirmed by confirmatory factor analysis – person support, self-support, and self-perspective support – indicated internal consistency and validated the three factors implicit in the theory Confirming Encounter. In addition, a new factor, concordance, was identified that is compatible with the theory. To conclude, despite the fact that a modified questionnaire have its limitations results demonstrate that the SAUC-model questionnaire seems to be a reliable and valid nursing quality-control measure with which foreign-born parents can evaluate the qualities of a confirming encounter with nurses. However, we suggest the need for testing the questionnaire in a larger population.
Dealing with Viking and Laval: From Theory to Practice
Authors: O’Donoghue Robert , Carr Bruce 
Published: September 2015

Abstract
This chapter examines the recent controversial decisions of the ECJ in Viking and Laval, focusing on how they are likely to be applied in practice. Firstly, it considers the rules regarding the applicable forum and the procedures for going to court in the UK, then it looks at when it can be said that an employer’s economic rights under EU law have been engaged and when there has been a ‘restriction’ on those rights. It goes on to address the core issue of the circumstances in which a ‘restriction’ on the relevant EU economic right pursues a ‘legitimate aim’ and then considers the key battleground in future cases falling under Viking and Laval, namely whether the industrial action is ‘proportionate’. Finally, it addresses an important, but unresolved, issue: the extent to which industrial action in breach of Articles 43 or 49 EC could give rise to liability in damages.
The Purpose of the EU Procurement Directives: Ends, Means and the Implications for National Regulatory Space for Commercial and Horizontal Procurement Policies
Authors: Arrowsmith Sue 
Published: September 2015

Abstract
There currently appears to be considerable confusion amongst regulators and stakeholders over the purpose of the EU’s directives on public procurement and lack of a clear vision of what the directives seek to achieve. Against this background this article has two objectives. First, it seeks to provide a framework for understanding the directives’ functions and their relationship with national policy. In this respect it identifies the ends and means that the directives do, or could, adopt and/or which have been ascribed to them, and considers the implications of each for national regulatory space. Secondly, for each of the ends and means it suggests a specific legal interpretation of its actual and potential role in the EU’s legal framework.
It is argued that the directives seek to promote the internal market and that they seek to do so solely by three means—prohibiting discrimination, implementing transparency, and removing barriers to access. It rejects, on the other hand, certain broader conceptions of the directives, including that they promote a single market by standardising procedures; that they replicate in the public market the competitive process of the private market; and that they seek value for taxpayers’ money. It is argued that rejection of these broader functions has important implications for the scope of national regulatory space, both as regards the ‘commercial’ aspects of public procurement—notably ensuring value for money and an efficient procurement process—and as regards ‘horizontal’ policies in the sense of policies that promote social and environmental objectives through public procurement.
6 The Court of Justice as a Labour Court
Authors: Davies ACL 
Published: September 2015

AbstractMany legal systems have specialist labour courts with jurisdiction over individual employment disputes or collective labour disputes or both. The literature identifies a number of possible justifications for the use of specialist labour courts. This chapter will engage in a critical examination of this literature in order to develop a framework for analysing the performance of courts (whether specialist or otherwise) in deciding labour law cases. We shall then apply that framework to some of the recent case law of the Court of Justice of the European Union.
The ILC’s Draft Articles Before the 69th Session of the UNGA: A Reawakening?
Authors: MORRIS-SHARMA Natalie Y. 
Published: September 2015

AbstractThe treatment by states, at the 69th session of the UNGA, of the ILC’s work on the responsibility of international organizations, the effects of armed conflicts on treaties, and the expulsion of aliens, offer some interesting points for reflection, particularly about the role of states in international law-making. This paper situates the UNGA’s consideration of the draft articles before it within the context of the recent trends of the UNGA’s commending of the ILC’s draft articles to the attention of governments, and of its use of technical roll-overs. In this regard, the paper questions whether the UNGA’s approach to the draft articles on the expulsion of aliens signals a reawakening of the UNGA. Against this backdrop, the paper also discusses the past practice of the UNGA when considering the draft articles of the ILC.
SAG-UPS attenuates proapoptotic SARM and Noxa to confer survival advantage to early hepatocellular carcinoma
Authors: Chang S C , Choo W Q W , Toh H C , Ding J L 
Published: September 2015

AbstractHepatocellular carcinoma (HCC) is a deadly cancer because of its commonly late diagnosis and limited treatment options. SAG (sensitive to apoptosis gene)-dependent UPS (ubiquitin–proteasome system) is a key switch between immune-mediated apoptosis and overactivation-mediated protumorigenesis, prompting us to hypothesize that SAG-UPS modulates chronic inflammation-induced tumorigenesis. Here, we investigated the molecular mechanism by which SAG-UPS regulates death/survival of liver cancer cells. By retrospective studies, we found reciprocal expressions of anti-/proapoptotic factors: SAG/SARM and SAG/Noxa in human primary HCC tissues – the antiapoptotic SAG was significantly upregulated whereas the proapoptotic SARM and Noxa were markedly downregulated, suggesting their involvement in hepatocarcinogenesis. Upregulated SAG-UPS effectively manipulates the levels of high-molecular-weight ubiquitinated SARM and Noxa in carcinoma tissues compared with corresponding normal tissues. SAG-overexpressing HCC cell lines display reduced SARM and Noxa (but not Bcl-2, Bax and Bcl-xL), suggesting that SARM and Noxa are specific substrates of SAG-dependent ubiquitination. SARM overexpression activated caspase-3 and caspase-9, reducing cell viability. SAG knockdown significantly elevated apoptosis with increased cytosolic cytochrome c, confirming SAG-mediated antiapoptosis in HCC. SAG overexpression stimulated protumorigenic cytokines, IL-1β, IL-6 and TNF, but not antitumorigenic IL-12p40 and anti-inflammatory IL-10. This is consistent with higher proinflammatory cytokines (IL-1β, IL-6 and TNF) in hepatoma compared with healthy tissues. Altogether, early stage-upregulated SAG-UPS exacerbates hepatocarcinogenesis progression, through: (1) ubiquitination-mediated degradation of proapoptotic SARM and Noxa; and (2) production of protumorigenic cytokines that induce a protumorigenic microenvironment, conferring survival advantage to HCC cells. Thus, we propose SAG-UPS to be an early diagnostic marker for HCC, and a potential target for therapeutics development.

AbstractDrought represents a major constraint on maize production worldwide. Understanding the genetic basis for natural variation in drought tolerance of maize may facilitate efforts to improve this trait in cultivated germplasm. Here, using a genome-wide association study, we show that a miniature inverted-repeat transposable element (MITE) inserted in the promoter of a NAC gene (ZmNAC111) is significantly associated with natural variation in maize drought tolerance. The 82-bp MITE represses ZmNAC111 expression via RNA-directed DNA methylation and H3K9 dimethylation when heterologously expressed in Arabidopsis. Increasing ZmNAC111 expression in transgenic maize enhances drought tolerance at the seedling stage, improves water-use efficiency and induces upregulation of drought-responsive genes under water stress. The MITE insertion in the ZmNAC111 promoter appears to have occurred after maize domestication and spread among temperate germplasm. The identification of this MITE insertion provides insight into the genetic basis for natural variation in maize drought tolerance.

AbstractUnderstanding magnetoresistance, the change in electrical resistance under an external magnetic field, at the atomic level is of great interest both fundamentally and technologically. Graphene and other two-dimensional layered materials provide an unprecedented opportunity to explore magnetoresistance at its nascent stage of structural formation. Here we report an extremely large local magnetoresistance of∼2,000% at 400 K and a non-local magnetoresistance of >90,000% in an applied magnetic field of 9 T at 300 K in few-layer graphene/boron–nitride heterostructures. The local magnetoresistance is understood to arise from large differential transport parameters, such as the carrier mobility, across various layers of few-layer graphene upon a normal magnetic field, whereas the non-local magnetoresistance is due to the magnetic field induced Ettingshausen–Nernst effect. Non-local magnetoresistance suggests the possibility of a graphene-based gate tunable thermal switch. In addition, our results demonstrate that graphene heterostructures may be promising for magnetic field sensing applications.
