Real-time integration of multi-parametric observations is expected to accelerate the process toward improved, and operationally more effective, systems for time-Dependent Assessment of Seismic Hazard (t-DASH) and earthquake short-term (from days to weeks) forecast. However, a very preliminary step in this direction is the identification of those parameters (chemical, physical, biological, etc.) whose anomalous variations can be, to some extent, associated with the complex process of preparation for major earthquakes. In this paper one of these parameters (the Earth’s emitted radiation in the Thermal InfraRed spectral region) is considered for its possible correlation withM ≥ 4 earthquakes occurred in Greece in between 2004 and 2013. The Robust Satellite Technique (RST) data analysis approach and Robust Estimator of TIR Anomalies (RETIRA) index were used to preliminarily define, and then to identify, significant sequences of TIR anomalies (SSTAs) in 10 years (2004–2013) of daily TIR images acquired by the Spinning Enhanced Visible and Infrared Imager on board the Meteosat Second Generation satellite. Taking into account the physical models proposed for justifying the existence of a correlation among TIR anomalies and earthquake occurrences, specific validation rules (in line with the ones used by the Collaboratory for the Study of Earthquake Predictability—CSEP—Project) have been defined to drive a retrospective correlation analysis process. The analysis shows that more than 93 % of all identified SSTAs occur in the prefixed space–time window around (M ≥ 4) earthquake's time and location of occurrence with a false positive rate smaller than 7 %. Molchan error diagram analysis shows that such a correlation is far to be achievable by chance notwithstanding the huge amount of missed events due to frequent space/time data gaps produced by the presence of clouds over the scene. Achieved results, and particularly the very low rate of false positives registered on a so long testing period, seems already sufficient (at least) to qualify TIR anomalies (identified by RST approach and RETIRA index) among the parameters to be considered in the framework of a multi-parametric approach to t-DASH.

Published: July 2015

Background

Idiopathic granulomatous mastitis (IGM) is a rare, benign, and chronic disease of the breast. Despite the various treatment approaches described for this disease, a gold standard treatment modality has not yet been defined. In this study, the effect of topical steroids was reviewed and assessed in patients with IGM.

Methods

The records of patients with IGM who were treated only with topical steroids were retrospectively reviewed. Patients were grouped as “completely healed,” “inadequately healed,” “stable,” “worsened,” or “recurred” if they had once healed but their symptoms returned. Patients whose skin changes were completely ameliorated were considered “completely healed.”

Results

All of the patients were women, and the average patient age was 35.7 years (range 24–48 years). During the average follow‐up of 37.2 months (range 12–72 months) in patients who received only topical steroid treatment, recurrence was observed in three patients (3/28, 10.7 %), and no side effects or steroid‐related complications occurred.

Conclusions

Topical steroids seem to be effective in the treatment of IGM characterized by skin changes. Prospective clinical studies would be useful in determining the clinical efficacy of topical steroids in the treatment of IGM.
Effects of 5-Fluorouracil, Etoposide and CdCl2 in Aquatic Oligochaeta Limnodrilus udekemianus Claparede (Tubificidae) Measured by Comet Assay

Published: July 2015

Genotoxicity of 5-fluorouracil (5-FU), etoposide (ET) and cadmium chloride (CdCl2) was evaluated in Limnodrilus udekemianus, cosmopolitan tubificid species, by alkaline single-cell gel electrophoresis (comet assay). Groups of 50 individuals were exposed in vivo in water-only short-term (96 h) tests to 5-FU (0.004, 0.04, 0.4, 4 and 40 μM), ET (0.004. 0.04, 0.4 and 4 μM) and CdCl2 (0.004, 0.04, 0.4, 4 and 40 μM). Mortality of worms was observed only for CdCl2 (4 and 40 μM). Cell viability lower than 70 % was detected for 5-FU (0.4, 4 and 40 μM), ET (4 μM) and CdCl2 (0.4 and 4 μM). All tested substances induced significant increase of DNA damage except 0.004 μM of ET. L. udekemianus being sensitive to all tested substances indicates that it can be used in ecogenotoxicology studies. Concern should be raised to cytostatics, especially to 5-FU, since concentration of 0.004 μM induced DNA damage is similar to ones detected in wastewaters.
Results of the Pavlik harness when treating Ortolani-positive hips: Predictors of failure and arthrographic findings
Authors: Vadillo Pablo , Encinas-Ullan Carlos Alberto , Moraleda Luis , Albiñana Javier
Published: July 2015

Background

Predictors of failure of the Pavlik harness in reducing and stabilizing an Ortolani-positive hip remain ‘unclear’. The purpose of this study is to investigate the success of the Pavlik harness when treating Ortolani-positive hips, to look for predictors of failure of the harness and to analyze the arthrographic findings among these failures.

Materials and methods

The medical records of 39 consecutive patients with an Ortolani-positive hip treated initially with a Pavlik harness were reviewed. Data regarding birth order, problems during pregnancy, presentation at birth, delivery, family history of DDH, gender, side involved, bilaterality, onset of treatment, problems related to use of the harness, and time until the harness reduced and stabilized the hip or was abandoned because of a failure were recorded. The presence of plagiocephaly, torticollis or foot deformity was also noted. We looked for predictors of failure among these aspects and report the arthrographic findings of the failures.

Results

The mean age when the harness was started was 16.7 days. The mean time until success or failure of the harness in reducing and stabilize the hip was 18.5 days. There were 8 (20.5 %) failures. Multigravida ( p = 0.026) and foot deformity ( p = 0.023) were associated with failure of the harness. On the other hand, problems during pregnancy ( p = 1), presentation at birth ( p = 0.078), c-section ( p = 0.394), family history of DDH ( p = 1), gender (0.313), torticollis ( p = 1), bilaterality ( p = 1) and onset of treatment ( p = 0.485) were not associated. Arthrographic abnormalities were found in all failures.

Conclusion

The Pavlik harness failed to reduce and stabilize the hip in 20.5 % of the newborns with an Ortolani-positive hip. Multigravida and foot deformity were statistically associated with failure of the harness. An anatomical obstacle for reduction was found in all hips with a harness failure. A more teratological than mechanical hip dislocation could be the reason for failure of the Pavlik harness.

Mental health outcomes at age 11 of very low birth weight infants in Ireland
Authors: McNicholas F. , Healy E. , White M. , Sheridan-Pereira M. , O’Connor N. , Coakley S. , Dooley B.
Published: July 2015

Aim

To compare mental health (MH) outcomes of and service use by children born under 1500 g in Ireland with a matched control group.

Method

Using a retrospective cohort design, semi-structured and standardised MH assessments were conducted with parents, teachers and youth.

Results

A total of 64 of 127 surviving children from a very low birth weight (VLBW) cohort from a National Maternity Hospital participated at a mean age of 11.6 years (s.d. 1.0), along with 51 matched controls. More VLBW children received clinical or borderline scores when rated by parents [χ2 (1, n=114)=7.3, p=0.007] or youths [χ2 (1, n=114)=4.83, p=0.028], but not by teachers [χ2 (1, n=114)=1.243, p=0.463]. There was no increase in the use of MH services. A main effect of birth weight remained on the parent Strengths and Difficulties Questionnaire [F (1, 88)=5.07, p<0.05) after controlling for intelligence quotient (IQ) and socio-economic status (SES), but only on hyperactivity in males. SES, rather than IQ or birth weight, predicted identification of problems by teachers [F (1, 82)=6.99, p=0.01).

Interpretations

Teachers miss MH difficulties and are influenced more by SES than by IQ or birth weight. This has implications for MH service access. Initial perinatal investment needs to be matched with ongoing surveillance and psychoeducation to ensure that disorders are recognised early and offered appropriate interventions.
Thin-sheet flow between coalescing bubbles
Authors: Munro James P. , Anthony Christopher R. , Basaran Osman A. , Lister John R.
Published: July 2015

When two spherical bubbles touch, a hole is formed in the fluid sheet between them, and capillary pressure acting on its tightly curved edge drives an outward radial flow which widens the hole joining the bubbles. Recent images of the early stages of this process (Paulsen et al., Nat. Commun., vol. 5, 2014) show that the radius of the hole $r_{\!E}$ at time $t$ grows proportional to $t^{1/2}$, and that the rate is dependent on the fluid viscosity. Here, we explain this behaviour in terms of similarity solutions to a third-order system of radial extensional-flow equations for the thickness and velocity of the sheet of fluid between the bubbles, and determine the growth rate as a function of the Ohnesorge number $\mathit{Oh}$. The initially quadratic sheet profile allows the ratio of viscous and inertial effects to be independent of time. We show that the sheet is slender for $r_{\!E}\ll a$ if $\mathit{Oh}\gg 1$, where $a$ is the bubble radius, but only slender for $r_{\!E}\ll \mathit{Oh}^{2}a$ if $\mathit{Oh}\ll 1$ due to a compressional boundary layer of length $L\propto \mathit{Oh}\,r_{\!E}$, after which there is a change in the structure but not the speed of the retracting sheet. For $\mathit{Oh}\ll 1$, the detailed analysis justifies a simple momentum-balance argument, which gives the analytic prediction $r_{\!E}\sim (32a{\it\gamma}/3{\it\rho})^{1/4}t^{1/2}$, where ${\it\gamma}$ is the surface tension and ${\it\rho}$ is the density.
On the mechanism of turbulent drag reduction with super-hydrophobic surfaces
Authors: Rastegari Amirreza , Akhavan Rayhaneh
Published: July 2015

The mechanism of turbulent drag reduction (DR) with super-hydrophobic (SH) surfaces is investigated by direct numerical simulation (DNS) and analysis of the governing equations in channel flow. The DNS studies were performed using lattice Boltzmann methods in channels with ‘idealized’ SH surfaces on both walls, comprised of longitudinal micro-grooves (MG), transverse MG, or micro-posts. DRs of$5\,\%$to$83\,\%$,$-4\,\%$to$20\,\%$, and$14\,\%$to$81\,\%$were realized in DNS with longitudinal MG, transverse MG, and micro-posts, respectively. By mathematical analysis of the governing equations, it is shown that, in SH channel flows with any periodic SH micro-pattern on the walls, the magnitude of DR can be expressed as$DR=U_{slip}/U_{bulk}+O({\it\varepsilon})$, where the first term represents the DR resulting from the effective slip on the walls, and the second term represents the DR or drag increase (DI) resulting from modifications to the turbulence dynamics and any secondary mean flows established in the SH channel compared to a channel flow with no-slip walls at the same bulk Reynolds number as the SH channel. Comparison of this expression to DNS results shows that, with all SH surface micro-patterns studied, between 80 % and 100 % of the DR in turbulent flow arises from the effective slip on the walls. Modifications to the turbulence dynamics contribute no more than 20 % of the total DR with longitudinal MG or micro-posts of high shear-free fraction (SFF), and a DI with transverse MG or micro-posts of moderate SFF. The effect of the SH surface on the normalized dynamics of turbulence is found to be small in all cases, and confined to additional production of turbulence kinetic energy (TKE) within a thin ‘surface layer’ of thickness of the order of the width of surface micro-indentations. Outside of this ‘surface layer’, the normalized dynamics of turbulence proceeds as in a turbulent channel flow with no-slip walls at the friction Reynolds number of the SH channel flow.
A coherence-matched linear source mechanism for subsonic jet noise
Authors: Baqui Yamin B. , Agarwal Anurag , Cavalieri André V. G. , Sinayoko Samuel
Published: July 2015

We investigate source mechanisms for subsonic jet noise using experimentally obtained datasets of high-Reynolds-number Mach 0.4 and 0.6 turbulent jets. The focus is on the axisymmetric mode which dominates downstream sound radiation for low polar angles and the frequency range at which peak noise occurs. A linearized Euler equation (LEE) solver with an inflow boundary condition is used to generate single-frequency hydrodynamic instability waves, and the resulting near-field fluctuations and far-field acoustics are compared with those from experiments and linear parabolized stability equation (LPSE) computations. It is found that the near-field velocity fluctuations closely agree with experiments and LPSE computations up to the end of the potential core, downstream of which deviations occur, but the LEE results match experiments better than the LPSE results. Both the near-field wavepackets and the sound field are observed directly from LEE computations, but the far-field sound pressure levels (SPLs) obtained are more than an order of magnitude lower than experimental values despite close statistical agreement of the near hydrodynamic field up to the potential core region. We explore the possibility that this discrepancy is due to the mismatch between the decay of two-point coherence with increasing distance in experimental flow fluctuations and the perfect coherence in linear models. To match the near-field coherence, experimentally obtained coherence profiles are imposed on the two-point cross-spectral density (CSD) at cylindrical and conical surfaces that enclose near-field structures generated with LEEs. The surface pressure is propagated to the far field using boundary value formulations based on the linear wave equation. Coherence matching yields far-field SPLs which show improved agreement with experimental results, indicating that coherence decay is the main missing component in linear models. The CSD on the enclosing surfaces reveals that the application of a decaying coherence profile spreads the hydrodynamic component of the linear wavepacket source on to acoustic wavenumbers, resulting in a more efficient acoustic source.
Experimental study on bubble dynamics subject to buoyancy
Authors: Zhang A. M. , Cui P. , Cui J. , Wang Q. X.
Published: July 2015

This paper is concerned with the dynamics of large bubbles subject to various strengths of buoyancy effects, which are associated with applications for underwater explosion. The bubble is produced by electric discharge in a low-pressure tank to enhance the buoyancy effects. Experiments are carried out for a bubble in an infinite field, below a free surface and above a rigid boundary. The effects of buoyancy are reflected by the dimensionless parameter ${\it\delta}=\sqrt{{\it\rho}gR_{m}/(p_{amb}-p_{v})}$, where $R_{m}$, $p_{amb}$, $p_{v}$, ${\it\rho}$ and $g$ are the maximum bubble radius, ambient pressure, saturated vapour pressure, density of water and the acceleration of gravity respectively. A systematic study of buoyancy effects is carried out for a wide range of ${\it\delta}$ from 0.034 to 0.95. A series of new phenomena and new features is observed. The bubbles recorded are transparent, and thus we are able to display and study the jet formation, development and impact on the opposite bubble surface as well as the subsequent collapsing and rebounding of the ring bubble. Qualitative analyses are carried out for the bubble migration, jet velocity and jet initiation time, etc. for different values of ${\it\delta}$. When a bubble oscillates below a free surface or above a rigid boundary, the Bjerknes force due to the free surface (or rigid boundary) and the buoyancy are in opposite directions. Three situations are studied for each of the two configurations: (i) the Bjerknes force being dominant, (ii) the buoyancy force being dominant and (iii) the two forces being approximately balanced. For case (iii), we further consider two subcases, where both the balanced Bjerknes and buoyancy forces are weak or strong. When the Bjerknes and buoyancy forces are approximately balanced over the pulsation, some representative bubble behaviours are observed: the bubble near free surface is found to split into two parts jetting away from each other for small ${\it\delta}$, or involutes from both top and bottom for large ${\it\delta}$. A bubble above a rigid wall is found to be subject to contraction from the lateral part leading to bubble splitting. New criteria are established based on experimental results for neutral collapses where there is no dominant jetting along one direction, which correlate well with the criteria of Blake et al. (J. Fluid Mech., vol. 170, 1986, pp. 479–497; J. Fluid Mech., vol. 181, 1987, pp. 197–212) but agree better with the experimental and computational results.
Governments, Parliaments and Legislative Activity
Authors: Bräuninger Thomas , Debus Marc , Wüst Fabian
Published: July 2015

Various strands of literature in comparative politics suggest that there is a differential impact of the type of government and their supporting legislative coalitions in parliamentary democracies, for example, in terms of their size and ideological heterogeneity, and on their potential to induce policy change. Most studies in this area focus on governments as agenda-setters, possibly neglecting the role of parliaments as a further key actor in policy making. In this article, we address the broader question as to how patterns of conflict within parliament effect legislative activity of governments and parliamentary actors. Through a simultaneous analysis of the success and event history of over 12,000 legislative bills in three parliamentary systems and one semi-presidential system from 1986 until 2003, we show how the interplay of actor motivations and institutional settings has a discriminating impact on the potential of both the government and parliament to induce policy change.

We define the quotient and complete NUOS-quotient map (NUOS stands for nonunital operator system) in the category of nonunital operator systems. We prove that the greatest reduced tensor product max0 is projective in some sense. Moreover, we define a pseudo unit in a nonunital operator system and give some necessary and sufficient conditions under which a nonunital operator system has an operator system structure.
HOMOMORPHISMS OF -MUNN ALGEBRAS AND APPLICATIONS TO SEMIGROUP ALGEBRAS

Published: July 2015

In this paper, for an arbitrary$\ell ^{1}$-Munn algebra$\mathfrak{A}$over a Banach algebra$A$with a sandwich matrix$P$, we characterise all homomorphisms from$\mathfrak{A}$to a commutative Banach algebra$B$. Especially, we study the character space of this algebra. Then, as an application, its character amenability is investigated. Finally, we apply these results to certain semigroups, which are called Rees matrix semigroups.
SOME RESULTS ON THE DIFFERENCE OF THE ZAGREB INDICES OF A GRAPH
Authors: AN MINGQIANG , XIONG LIMING
Published: July 2015

The classical first and second Zagreb indices of a graph $G$ are defined as $M_{1}(G)=\sum _{v\in V(G)}d(v)^{2}$ and $M_{2}(G)=\sum _{e=uv\in E(G)}d(u)d(v),$ where $d(v)$ is the degree of the vertex $v$ of $G.$ Recently, Furtula et al. [‘On difference of Zagreb indices’, Discrete Appl. Math.178 (2014), 83–88] studied the difference of $M_{1}$ and $M_{2},$ and showed that this difference is closely related to the vertex-degree-based invariant $RM_{2}(G)=\sum _{e=uv\in E(G)}[d(u)-1][d(v)-1]$, the reduced second Zagreb index. In this paper, we present sharp bounds for the reduced second Zagreb index, given the matching number, independence number and vertex connectivity, and we also completely determine the extremal graphs.

It is an open question whether every derivation of a Fréchet GB$^{\ast }$-algebra $A[{\it\tau}]$ is continuous. We give an affirmative answer for the case where $A[{\it\tau}]$ is a smooth Fréchet nuclear GB$^{\ast }$-algebra. Motivated by this result, we give examples of smooth Fréchet nuclear GB$^{\ast }$-algebras which are not pro-C$^{\ast }$-algebras.

A NOTE ON CYCLIC AMENABILITY OF THE LAU PRODUCT OF BANACH ALGEBRAS DEFINED BY A BANACH ALGEBRA MORPHISM
Authors: ABTAHI F. , GHAFARPANAH A.
Published: July 2015

Let $T$ be a Banach algebra homomorphism from a Banach algebra ${\mathcal{B}}$ to a Banach algebra ${\mathcal{A}}$ with $\Vert T\Vert \leq 1$. Recently, Bhatt and Dabhi [‘Arens regularity and amenability of Lau product of Banach algebras defined by a Banach algebra morphism’, Bull. Aust. Math. Soc.87 (2013), 195–206] showed that cyclic amenability of ${\mathcal{A}}\times _{T}{\mathcal{B}}$ is stable with respect to $T$, for the case where ${\mathcal{A}}$ is commutative. In this note, we address a gap in the proof of this stability result and extend it to an arbitrary Banach algebra ${\mathcal{A}}$.
Quantitation of viable Coxiella burnetii in milk using an integrated cell culture-polymerase chain reaction (ICC-PCR) assay
Authors: Stewart Diana , Shieh Y-Carol , Tortorello Mary , Kukreja Ankush , Shazer Arlette , Schlesser Joseph
Published: July 2015

The obligate intracellular pathogen Coxiella burnetii has long been considered the most heat resistant pathogen in raw milk, making it the reference pathogen for determining pasteurisation conditions for milk products. New milk formulations and novel non-thermal processes require validation of effectiveness which requires a more practical method for analysis than using the currently used animal model for assessing Coxiella survival. Also, there is an interest in better characterising thermal inactivation of Coxiella in various milk formulations. To avoid the use of the guinea pig model for evaluating Coxiella survival, an Integrated Cell Culture-PCR (ICC-PCR) method was developed for determining Coxiella viability in milk. Vero cell cultures were directly infected from Coxiella-contaminated milk in duplicate 24-well plates. Viability of the Coxiella in milk was shown by a ≥0·5 log genome equivalent (ge)/ml increase in the quantity of IS111a gene from the baseline post-infection (day 0) level after 9–11 d propagation. Coxiella in skim, 2%, and whole milk, and half and half successfully infected Vero cells and increased in number by at least 2 logs using a 48-h infection period followed by 9-d propagation time. As few as 125 Coxiella ge/ml in whole milk was shown to infect and propagate at least 2 logs in the optimised ICC-PCR assay, though variable confirmation of propagation was shown for as low as 25 Coxiella ge/ml. Applicability of the ICC-PCR method was further proven in an MPN format to quantitate the number of viable Coxiella remaining in whole milk after 60 °C thermal treatment at 0, 20, 40, 60 and 90 min.
Nature and extent of human–elephant Elephas maximus conflict in central Nepal

Published: July 2015

Human–elephant conflict is one of the main threats to the long-term survival of the Asian elephant Elephas maximus. We studied the nature and extent of human–elephant interactions in the buffer zones of Chitwan National Park and Parsa Wildlife Reserve in Nepal, through household questionnaire surveys, key informant interviews, site observations, and analysis of the reported cases of damage during January 2008–December 2012. During this 5-year period 290 incidents of damage by elephants were reported, with a high concentration of incidents in a few locations. Property damage (53%) was the most common type of damage reported. Crop damage was reported less often but household surveys revealed it to be the most frequent form of conflict. There were also human casualties, including 21 deaths and four serious injuries. More than 90% of the human casualties occurred during 2010–2012. More than two thirds of the respondents (70%) perceived that human–elephant conflict had increased substantially during the previous 5 years. Despite the increase in incidents of human–elephant conflict in the area, 37% of respondents had positive attitudes towards elephant conservation. Our findings suggest that public awareness and compensation for losses could reduce conflict and contribute to ensuring coexistence of people and elephants in this human-dominated landscape.
When opportunity lags: human development policymaking in Arctic regions
Authors: Klick Matthew
Published: July 2015

The popular narrative of Arctic development continues to dwell on melting sea ice, untapped oil and gas reserves, an icebreaker arms race and the perils and potential of rapid industrialisation. Rarely is the welfare of Arctic populations considered in a holistic sense and with a precise call for policy change. The recently released Arctic human development report II, echoing the more widely distributed human development reports generated by the United Nations, does just this. Unfortunately, despite the laudable efforts of the authors to embrace the more systemic drivers of poverty and marginalisation, the report fails to account for governmental and policy shortcomings which continue to limit health and opportunity, while obscuring tangible pathways to prosperity for Arctic populations. This comment is intended as a call, amongst the fervour of Arctic exploitation, to refocus attention on the unmistakable disparities in public health and well-being that persist in the Arctic regions of otherwise wealthy countries, and to incorporate globally practised perceptions of human development, including the role of social and political marginalisation in explaining health and prosperity discrepancies, which have been largely lacking in Arctic development discourse, and practice.
Welfare Capitalism in Crisis: A Qualitative Comparative Analysis of Labour Market Policy Responses to the Great Recession
Authors: SHAHIDI FARAZ VAHID
Published: July 2015

Social policy responses to the recent economic crisis have varied considerably across advanced capitalist countries. This study aims to explain this cross-national diversity through a qualitative comparative analysis of labour market policy responses to the Great Recession across eighteen advanced welfare states. The results of the study suggest that theories of welfare state change that attribute theoretical centrality to political and institutional factors do not provide a compelling explanation for patterns of labour market reform observed since the onset of the economic crisis. Rather, they appear to be explained principally in terms of the variable fiscal capacity of the state. In particular, the study findings indicate that the presence of fiscal crisis has acted as a necessary (but insufficient) condition for the presence of recommodification, while the absence of fiscal crisis has acted as a sufficient (but unnecessary) condition for the absence of recommodification. These empirical developments suggest that there is a need for a scholarly return to the problematic relationship between capitalism and the welfare state.
Understanding teaching needs development
Authors: Beck Sarah R.

To fully understand teaching, we need to know how it develops ontogenetically. Developmental questions about the emergence of different types of teaching behaviour in young humans and the psychological capabilities that underpin them are currently overlooked. Incorporating the individual's development from learner to teacher would expand the scope and impact of Kline's useful framework.

Cognition as the tip of the emotional iceberg: A neuro-evolutionary perspective
Authors: Bos Peter A. , Brummelman Eddie , Terburg David
Published: July 2015

We emphasize the importance of a neuroevolutionary perspective in moving beyond the cognition-emotion dichotomy. Cognitive behavior depends on cortical structures firmly rooted in the emotional brain from which they have evolved. As such, there cannot be cognition without emotion. Endocrine regulation of amygdala connectivity, a neural “switch” between impulsivity and deliberation, further underscores the phylogenetic impossibility of a cognition-emotion dichotomy.
Integration of cognition and emotion in physical and mental actions in musical and other behaviors
Authors: Gardiner Martin Frederick
Published: July 2015

Integration of cognition and emotion, discussed by Pessoa in The Cognitive-Emotional Brain (2013), is further illustrated by music. In music, I argue, this integration begins during mental control of the actions by which musical sounds are produced. Many emotional reactions to the music we hear are also strongly related to the actions by which musical sounds are produced. Studies involving music can further illuminate the integration of emotion and control of action throughout behavior.
Behavioral evidence for a continuous approach to the perception of emotionally valenced stimuli

On theory integration: Toward developing affective components within cognitive architectures
Authors: Olds Justin M. , Marewski Julian N.
Published: July 2015

In The Cognitive-Emotional Brain, Pessoa (2013) suggests that cognition and emotion should not be considered separately. We agree with this and argue that cognitive architectures can provide steady ground for this kind of theory integration and for investigating interactions among underlying cognitive processes. We briefly explore how affective components can be implemented and how neuroimaging measures can help validate models and influence theory development.
The cognitive-emotional amalgam
Authors: Pessoa Luiz
Published: July 2015

In the précis to The Cognitive-Emotional Brain, I summarize a framework for understanding the organization of cognition and emotion in the brain. Here, I address six major themes that emerged in the commentaries: (1) emotional perception and automaticity; (2) the status of cognition and emotion: together or separate? (3) evolutionary implications for the understanding of emotion and cognition; (4) the diverse forms of cognitive-emotional integration; (5) dual process theories; and (6) functional diversity of brain regions/networks and cognitive ontologies. The central argument is, again, that cognition and emotion are so highly interactive, and indeed integrated, that these two elements blend into a new amalgam.
FACTORS INFLUENCING SENSITIVITY TO LEXICAL TONE IN AN ARTIFICIAL LANGUAGE

Published: July 2015

This study examined whether musical training, ethnicity, and experience with a natural tone language influenced sensitivity to tone while listening to an artificial tone language. The language was designed with three tones, modeled after level-tone African languages. Participants listened to a 15-min random concatenation of six 3-syllable words. Sensitivity to tone was assessed using minimal pairs differing only in one syllable (nonword task: e.g.,to-kà-sucompared toca-fí-to) or only in tone (tone task: e.g.,to-kà-sucompared toto-ká-su). Proficiency in an East Asian heritage language was the strongest predictor of success on the tone task. Asians without tone language experience were no better than other ethnic groups. We conclude by considering implications for research on second language learning, especially as approached through artificial language learning.
Pinning of interfaces in a random elastic medium and logarithmic lattice embeddings in percolation
Authors: Dondl Patrick W. , Scheutzow Michael , Throm Sebastian
Published: July 2015

For a model of a driven interface in an elastic medium with random obstacles we prove the existence of a stationary positive supersolution at non-vanishing driving force. This shows the emergence of a rate-independent hysteresis through the interaction of the interface with the obstacles despite a linear (force = velocity) microscopic kinetic relation. We also prove a percolation result, namely, the possibility to embed the graph of an only logarithmically growing function in a next-nearest neighbour site percolation cluster at a non-trivial percolation threshold.
A higher-order-decay result for the dynamo equation with an application to the toroidal velocity theorem
Authors: Kaiser Ralf
Published: July 2015

In dynamo theory the distinction between decaying (in time) magnetic fields and those that do not is of crucial importance. Often decay is not manifest for the magnetic field itself but only for a single component or a scalar potential. Typically these auxiliary quantities satisfy evolution equations of the same type as the original induction equation. We prove here for these equations a theorem relating the decay of a solution to the decay of its higher derivatives. This result allows us to relate the decay of an auxiliary quantity to that of the magnetic field and, moreover, to relate integral decay to pointwise decay. As an application we strengthen the ‘toroidal velocity theorem’ in that we demonstrate pointwise decay of the magnetic field and electric current to zero under the conditions of this theorem.
On stability and asymptotic behaviours for a degenerate Landau–Lifshitz equation
Authors: Yan Baisheng
Published: July 2015

In this paper we study the problem concerning stability and asymptotic behaviours of solutions for a degenerate Landau–Lifshitz equation in micromagnetics involving only the non-local magnetostatic energy. Due to the lack of derivative estimates, we do not have the compactness needed for strong convergence and the natural convergence is weak* convergence. By formulating the problem in a new framework of differential inclusions, we show that the Cauchy problems for such an equation are not stable under the weak* convergence of initial data. For the asymptotic behaviours of weak solutions, we establish an estimate on the weak* ω-limit sets that is valid for all initial data satisfying the saturation condition.
Compensation for Stochastic Error of Gyros in a Dual-axis Rotational Inertial Navigation System
Authors: Zheng Zhichao , Han Songlai , Yue Jin , Yuan Linglong
Published: July 2015

A dual-axis rotational Inertial Navigation System (INS) has received wide attention in recent years because of high performance and low cost. However, some errors of inertial sensors such as stochastic errors are not averaged out automatically during navigation. Therefore a Twice Position-fix Reset (TPR) method is provided to enhance accuracy of a dual-axis rotational INS by compensating stochastic errors. According to characteristics of an azimuth error introduced by stochastic errors of an inertial sensor in the dual-axis rotational INS, both an azimuth error and a radial-position error are much better corrected by the TPR method based on an optimised error propagation equation. As a result, accuracy of the dual-axis rotational INS is prominently enhanced by the TPR method, as is verified by simulations and field tests.
The Engaging Power of English-Language Promotion in Franco's Spain
Authors: MARTÍN GARCÍA ÓSCAR J. , RODRÍGUEZ JIMÉNEZ FRANCISCO J.
Published: July 2015

The United States' support for the Franco dictatorship, along with British dominion over Gibraltar, caused an increasing sense of frustration towards the United States and United Kingdom amongst broad sectors of the Spanish public during the 1960s and 1970s. Growing resentment towards the Anglo-American presence in Spain threatened to jeopardise the geopolitical objectives of these two governments given the strategic importance of the Iberian Peninsula in the Cold War. Both the Americans and the British identified the promotion of the English language as a cultural tool to develop empathy amongst those Spaniards who would drive forward the eventual transition to a post-Franco era. This ‘soft power’ strategy fit perfectly with the pro-modernisation efforts taking place in several parts of the world. English teaching did not serve as a magic potion, however. Cultural seduction was not a cure-all to right the wrongs inflicted by the Anglo-American geostrategic priorities. This article explores the benefits and limitations of English language promotion in Franco's Spain and reflects on the ability of ‘soft power’ to influence what was a rather hostile hard-power context.
Modular action language
Authors: INCLEZAN DANIELA , GELFOND MICHAEL
Published: July 2015

The paper introduces a new modular action language,${\mathcal ALM}$, and illustrates the methodology of its use. It is based on the approach of Gelfond and Lifschitz (1993,Journal of Logic Programming 17, 2–4, 301–321; 1998,Electronic Transactions on AI 3, 16, 193–210) in which a high-level action language is used as a front end for a logic programming system description. The resulting logic programming representation is used to perform various computational tasks. The methodology based on existing action languages works well for small and even medium size systems, but is not meant to deal with larger systems that requirestructuring of knowledge.$\mathcal{ALM}$is meant to remedy this problem. Structuring of knowledge in${\mathcal ALM}$is supported by the concepts ofmodule(a formal description of a specific piece of knowledge packaged as a unit),module hierarchy, andlibrary, and by the division of a system description of${\mathcal ALM}$into two parts:theoryandstructure. Atheoryconsists of one or more modules with a common theme, possibly organized into a module hierarchy based on adependency relation. It contains declarations of sorts, attributes, and properties of the domain together with axioms describing them.Structuresare used to describe the domain's objects. These features, together with the means for defining classes of a domain as special cases of previously defined ones, facilitate the stepwise development, testing, and readability of a knowledge base, as well as the creation of knowledge representation libraries.
RECLAIMING THE MARGINS: SEITA TANSŌ'SSUIKODEN HIHYŌKAIAND THE POETICS OF CROSS-CULTURAL INFLUENCE
Authors: Hedberg William C.
Published: July 2015

This article focuses on the literary criticism of the Edo-period scholar, Seita Tansō (1719–1785). Although a historian by vocation, Tansō additionally lectured extensively on the Chinese vernacular novel,Shuihu zhuan(Jp.Suikoden, En.The Water Margin). While earlier generations of Chinese fiction aficionados in Japan had also discussedShuihu zhuan, early eighteenth-century analysis was primarily limited to philological explication—a task necessitated by the extensive use of colloquial language in the novel. In contrast to this tradition of philological exegesis, Tansō turned his attention to the ethical content and literary structure ofShuihu zhuan. Tansō was heavily influenced by the writing of the Chinese fiction commentator Jin Shengtan (1608–1661), and in this article, I discuss Tansō's use of Jin's fiction criticism in the construction of his own interpretation of the novel. I argue that the dissemination of Chinese novels in Edo-period Japan cannot be discussed without an understanding of Japanese engagement with Chinese narrative theory, and I identify Seita Tansō as an important figure in a transition from philological to more purely narratological analysis of Chinese vernacular fiction.
THE PHANTASM OF THE WESTERN CAPITAL (SŎGYŎNG): IMPERIAL KOREA'S REDEVELOPMENT OF P'YŎNGYANG, 1902–1908
Authors: Park Eugene Y.
Published: July 2015

The Western Capital (Sŏgyŏng) project was of ideological, cultural, and strategic significance for the Empire of Korea (1897–1910) struggling for survival in the age of imperialism. This study argues that Imperial Korea's understanding of its place in the civilized world of the past, present, and future inspired redeveloping P'yŏngyang as the secondary capital. The advocates cited the history of the city in particular and of the nation in general to legitimize the project. Also, status-conscious specialistchungin(“middle people”), a newly prominent social group with loyalist members, played active roles. Moreover, responding to the deteriorating Russo-Japanese relations, Korea began preparing the nation's secondary capital, located within a neutral zone that Russia proposed to Japan. From the outset, the critics of the project highlighted funding constraints, a heavy tax burden on the local population, and rapacious officials exploiting the situation. The Japanese victory over Russia in 1905 effectively ended the project, but the memory of P'yŏngyang's status as the secondary capital outlived the Empire of Korea and the subsequent Japanese colonial rule before the city became the national capital of the Democratic People's Republic of Korea, established in 1948.
Balancing competences: How institutional cosmopolitanism can manage jurisdictional conflicts
Authors: KLATT MATTHIAS
Published: July 2015

Conflicts of competences are ubiquitous in law. They represent a serious challenge, in particular, to global constitutionalism and institutional cosmopolitanism. This article argues from a participant’s perspective, following a normative-analytical approach. It develops new taxonomy of competence conflicts. In essence it defends a flexible legal solution to competence conflicts that is inspired by the idea of practical institutional concordance and provides a middle way between strict legal solutions and political appeals for dialogue. Legal authority beyond the state and competence admit of degrees and variability, depending on the legal and factual circumstances of the case at issue. This understanding is enabled by interpreting competences as formal principles. Drawing on research by Alexy and Kumm the details of balancing competences as a distinct legal method are elaborated, using a triadic scale and various factors for determining the concrete weight of a competence. The theory of balancing competences is then applied to the example of competence conflicts in the multilevel system of fundamental rights protection in the EU. In result, a universal but case-sensitive theory is presented that optimally combines flexibility and stability and allows for a pluralist understanding of sovereignty. Institutional cosmopolitanism is thus defended against sceptical pluralism.
Constituent power and people-as-the-governed: About the ‘invisible’ people of political and legal theory
Authors: NOOTENS GENEVIÈVE
Published: July 2015

The core promise of the modern concept of constituent power is to make the people-as-the-governed active participants in the shaping and ruling of political regimes. Its development was related to the consolidation of the modern state. Current circumstances, though, raise the issue of the possibility of a non-state based concept of constituent power, and of appropriate constituencies. The article argues that dominant views have made the people-as-the-governed capacity to act dependent upon state sovereignty, whereas the latter actually was informed by theses antithetical to popular sovereignty. In order to show how a non-state based concept of constituent power may be articulated, the article builds on a critique of Martin Loughlin’s attempt to capture the structure of beliefs that frames the idea of the state and the function of constituent power within that structure. The first part of the article focuses on the main elements of such a theory in order to situate its basic assumptions about constituent power. The second discusses the issues raised by such a conception, amongst other things as to the status granted to the structure of beliefs that frames the idea of the modern polity in Loughlin’s perspective; this discussion opens the way to an alternative conception of constituent power, one that stresses that the core fact of the political is that people are always already embedded in relations of power that are not restricted to the state, relations in the course of which they strive to achieve their civic freedom. Political power is not necessarily made public until the people-as-the-governed, in challenging the boundaries of the polity, claim it.
