DISTANT SHORES: A HISTORIOGRAPHIC VIEW ON TRANS-SAHARAN SPACE
Authors: LECOCQ BAZ
Published: January 2015

This article addresses how scholarship has formulated human connections and ruptures over the Sahara. However, these formulations were, and still are, based in both physical and discursive realities that have been developed in Africa itself. The idea of a dividing Sahara is based on historical political divisions – despite a homogenous political culture in the region – and by locally developed notions of race and religion, brought about by trade and justified in Islamic religious discourse. The Saharan divide acquired a new reading in colonial historiography, which, in turn, informed scholarly work until well into the 1960s. I will suggest that both colonial and postcolonial research on the differences and connections between the Saharan shores are suffering from a civilisational bias towards North Africa.
EXPLAINING THE FERTILITY PUZZLE IN SRI LANKA
Authors: WIJESEKERE GAMINIRATNE , ARUNACHALAM DHARMA
Published: January 2015

Fertility transition in Sri Lanka began in the mid-1960s and the declining trend continued over the decades. The Demographic and Health Survey (DHS) of 2000 showed the total fertility rate (TFR) reaching 1.9 births per woman, a level below replacement fertility. The next DHS of 2006/7 showed a TFR of 2.3. Some have interpreted this pattern as indicating a reversal of the fertility transition. This paper casts doubts on the below-replacement fertility revealed in the 2000 survey.
Modulational instability of ion-acoustic waves in fully relativistic two-component plasma
Authors: Ghosh B. , Banerjee S.
Published: January 2015

Nonlinear amplitude modulation of ion-acoustic waves (IAWs) in a fully relativistic unmagnetized two-fluid plasma has been theoretically studied by using complete set of fully relativistic dynamic equations. To describe the nonlinear evolution of the wave envelope a nonlinear Schrödinger (NLS) equation is derived by using standard multiple scale perturbation technique. Using this equation it is shown that the wave becomes modulationally unstable as the wavenumber exceeds certain critical value. This critical wavenumber is found to decrease with increase in relativistic effect. The instability growth rate has also been calculated numerically for different values of plasma drift velocity. The growth rate is shown to decrease with increase in the relativistic effect.
Material poverty and multiple deprivation in Britain: the distinctiveness of multidimensional assessment
Authors: Hick Rod
Published: January 2015

Poverty analysis is currently undergoing a multidimensional turn, increasingly focusing on the many ways in which human life can be impoverished and not just on material poverty. In this paper, we present an analysis of material poverty and multiple deprivation in Britain, which is inspired by the capability approach. We argue that the additional complexity of multidimensional analysis requires that it provides some insight not achieved by a more straightforward approach focusing on material poverty alone. Our findings indicate that whether a multidimensional assessment identifies different people as being in poverty depends on whether our interest is in identifying vulnerable individuals or in identifying vulnerable groups and whether we focus on dimensions in aggregate or disaggregate forms. We find that, although material poverty and multiple deprivation identify very different individuals, they display greater congruence in terms of identifying vulnerable groups, especially where aggregate measures are used.
The Neglected Art: Trends and Transformations in British Concert Party Entertainment, 1850–1950
Authors: Ince Bernard
Published: January 2015

The genre commonly referred to as the ‘concert party’ remains largely neglected by scholars of popular entertainment. In this article Bernard Ince presents a new reading of this most distinctive and underrated branch of theatrical activity. The period before the First World War saw the growth of an ‘industry’ which provided seaside amusement during the summer months. During the inter-war years, however, a more sophisticated form developed whose performative characteristics drew increasingly on revue and cabaret. The period after the Second World War saw further adaptations that gave rise to the summer show, an altogether more lavish spectacle that nonetheless inherited much of the concert party ethos of earlier times. Changes in audience expectations and public holiday preferences, the catastrophe of the two world wars, and the emergence of radio and film were challenges all successfully negotiated, further underscoring the resilience and adaptability of the genre. In the wider context, the concert party not only offered a critical path to the variety stage but in the simplicity of basic form also provided a template for experimentation and innovation. The author is an independent theatre historian.
‘Supernatural Soliciting’: Pathways from Betrayal to Retribution in Macbeth and Yotsuya Kaidan
Authors: Sorgenfrei Carol Fisher
Published: January 2015

Although written two centuries apart and in divergent cultures, the kabuki play Tōkaidō Yotsuya Kaidan and Shakespeare's Macbeth exhibit marked similarities (as well as differences) in plot. Here, Carol Fisher Sorgenfrei analyzes some of the ways that these plays reflect (mostly male) anxieties regarding shifting patterns of gender and political power in Jacobean England and Tokugawa Japan. Professor Emerita of Theatre at UCLA, Carol Fisher Sorgenfrei is a specialist in Japanese theatre and intercultural performance, and was recently a Research Fellow at the International Research Institute in Interweaving Performance Cultures at the Free University, Berlin. She is the author of Unspeakable Acts: the Avant-Garde Theatre of Terayama Shūji and Postwar Japan (University of Hawaii, 2005) and co-author of Theatre Histories: an Introduction (Routledge, third edition, 2015). She is also a playwright whose latest play, Ghost Light, is a contemporary fusion of Macbeth and Yotsuya Ghost Stories, in which the ghost of a Japanese-American actress returns to wreak vengeance on the husband who betrayed her. The play will be staged as an Equity Showcase in New York in Autumn 2015.
Steady states with unbounded mass of the Keller–Segel system

Published: January 2015

We consider the boundary-value problem

where Br0 is the ball of radius r0 in ℝN, N ≥ 2, λ > 0 and ν is the outer normal derivative at ∂Br0. This problem is equivalent to the stationary Keller—Segel system from chemotaxis. We show the existence of a solution concentrating at the boundary of the ball as λ goes to 0.
Unfolding plane curves with cusps and nodes
Authors: Ballesteros Juan J. Nuño
Published: January 2015

Given an irreducible surface germ (X, 0) ⊂ (ℂ3, 0) with a one-dimensional singular set Σ, we denote by δ1 (X, 0) the delta invariant of a transverse slice. We show that δ1 (X, 0) ≥ m0 (Σ, 0), with equality if and only if (X, 0) admits a corank 1 parametrization f :(ℂ2, 0) → (ℂ3, 0) whose only singularities outside the origin are transverse double points and semi-cubic cuspidal edges. We then use the local Euler obstruction Eu(X, 0) in order to characterize those surfaces that have finite codimension with respect to -equivalence or as a frontal-type singularity.
Symmetry breaking in the minimization of the second eigenvalue for composite membranes
Authors: Anedda Claudia , Cuccu Fabrizio
Published: January 2015

Let Ω ⊂ ℝN be an open bounded connected set. We consider the eigenvalue problem –Δu = λρu in Ω with Dirichlet boundary condition, where ρ is an arbitrary function that assumes only two given values 0 < α < β and is subject to the constraint ∫Ωρ dx = αγ + β(|Ω| – γ) for a fixed 0 < γ < |Ω|. Cox and McLaughlin studied the optimization of the map ρ ⟼ λk(ρ), where λk is the kth eigenvalue. In this paper we focus our attention on the case when N ≥ 2, k = 2 and Ω is a ball. We show that, under suitable conditions on α, β and γ, the minimizers do not inherit radial symmetry.

Authors: Dubuisson Carine , Lioret Sandrine , Dufour Ariane , Calamassi-Tran Gloria , Volatier Jean-Luc , Lafay Lionel , Turck Dominique
Published: January 2015

Objective

Recently, school meal composition regulations have been implemented in France in order to improve the nutritional status of children. The present study investigated the link between school lunch attendance and the food intakes of schoolchildren aged 3–17 years.

Design

Second French cross-sectional dietary survey (2006–2007). Eating frequencies were assessed for twenty-four food groups with a 7 d food record. Eating locations were recorded for main meals. Food group intakes at weekday lunches were compared for the school canteen and for other locations. The children’s overall dietary intake was compared based on school lunch attendance.

Setting

Mainland France.

Subjects

Schoolchildren aged 3–17 years (n 1068).

Results

Lunchtime food intake differed between the school canteen and other locations. Some intakes at school canteens were more in accordance with the regulations (more fruit and vegetables, fish and dairy products, and less sandwiches, soft drinks, chocolate and confectionery), whereas others highlighted needs for improvement (more sweet biscuits and pastries, ice cream and dairy desserts, pizzas and salty pastries). Many of these differences were also observed in the children’s overall diet: children regularly attending school lunches ate more mashed fruit, fish and sweet biscuits or pastries, and less sandwiches and soft drinks. The link between school lunch attendance and overall diet was less pronounced in secondary-school children.

Conclusions

School canteen attendance is associated with both potentially beneficial and deleterious differences in the lunchtime and overall diets of French children. These findings are important to consider when setting national regulations for school meal composition.
Kantian Moral Striving
Authors: Biss Mavis
Published: January 2015

This paper focuses on a single question that highlights some of the most puzzling aspects of Kant’s explanation of the duty of moral self-perfection. What kinds of activity count as striving for purity in one’s disposition to duty, or strength of will? I argue that a dominant strand of Kant’s approach to moral striving does not fit familiar models of striving. I seek to address this problem in a way that avoids the flaws of synchronic and atomistic approaches to moral self-discipline by developing an account of Kantian moral striving as an ongoing contemplative activity complexly engaged with multiple forms of self-knowledge.
Kant’s Mathematical Sublime and the Role of the Infinite: Reply to Crowther
Authors: Smith Simon D.
Published: January 2015

This paper offers an analysis of Kant’s account of the mathematical sublime with reference to his claim that ‘Nature is thus sublime in those of its appearances the intuition of which brings with them the idea of its infinity’ (CJ, 5: 255). In undertaking this analysis I challenge Paul Crowther’s interpretation of this species of aesthetic experience, and I reject his interpretation as not being reflective of Kant’s actual position. I go on to show that the experience of the mathematical sublime is necessarily connected with the progression of the imagination in its move towards the infinite.
Status functions and institutional facts: reply to Hindriks and Guala
Authors: SEARLE JOHN R.
Published: January 2015

Hindriks and Guala (2014) hope to provide a unified account of institutional theory that will combine the accounts of regulative rules, constitutive rules, and equilibria. I argue that only the constitutive rule approach has any possibility of success, and that the other two cannot even pose the right questions, much less answer them. Hindriks and Guala think constitutive rules can be reduced to regulative rules. I argue that their reduction is mistaken. The key to understanding social ontology is understanding status functions.
Taking up space on earth: Theorizing territorial rights, the justification of states and immigration from a global standpoint
Authors: RISSE MATHIAS
Published: January 2015

The author’s 2012 bookOn Global Justicegives pride of place to the idea that humanity collectively owns the earth. Independently, there has been a flourishing literature on the justification of rights to territory. Central to this discussion are a Kantian and a Lockean approach. This paper recapitulates the author’s approach to humanity’s collective ownership of the earth and argues that, properly understood, both of those approaches should integrate the global standpoint constituted thereby. However, the goal here is not to amend the Kantian and Lockean approaches to territory, but to refute them. To that end the paper also argues that both approaches endorse an unacceptably strong view of the justifiability of states and should therefore be rejected. The view inOn Global Justiceemerges vindicated, according to which territorial rights, the justification of states and immigration all need to be theorized together, and need to be theorized from a genuinely global standpoint.
Balancing and judicial self-empowerment: A case study on the rise of balancing in the jurisprudence of the German Federal Constitutional Court
Authors: PETERSEN NIELS
Published: January 2015

Many critics of the proportionality principle argue that balancing is an instrument of judicial self-empowerment. This contribution argues that the relationship between balancing and judicial power is more complex. Balancing does not necessarily create judicial power, but it presupposes it. This argument is confirmed through a case study of the German Federal Constitutional Court. The analysis shows that the German Constitutional Court was very reluctant to base decisions, in which it overturned legislation, on balancing in the first two and a half decades of its jurisprudence. However, in the late 1970s, once the Court had strengthened its own institutional position, it increasingly relied on balancing when declaring laws as incompatible with the constitution. Then, balancing developed into the predominant argumentation framework of constitutional review that it is today in the Court’s jurisprudence.
Mental health medication and service utilisation before, during and after war: a nested case–control study of exposed and non-exposed general population, ‘at risk’, and severely mentally ill cohorts
Authors: Gelkopf M. , Kodesh A. , Werbeloff N.
Published: January 2015

Aims.

To examine changes in service utilisation before, during and after the 2006 Lebanon War – a 34-day military conflict in northern Israel and Lebanon – among three groups: general population, people ‘at risk’ for depression or anxiety and severely mentally ill individuals. Given that exposure to traumatic events is a pathogenic factor known to cause and exacerbate psychiatric distress and disorder, we hypothesised that healthcare service utilisation would increase in populations exposed to war, especially among more vulnerable populations such as those with mental illness.

Method.

A nested case–control design was used to examine changes in health care utilisation and use of psychiatric medication as recorded by the databases of Maccabi Healthcare Services (MHS), one of Israel's largest health maintenance organisations (HMOs). Purchases of benzodiazepines, antidepressants and antipsychotic medications were identified from all the medications purchased in pharmacies by MHS members during 2006. Drug consumption data were expressed as defined daily doses (DDDs), summing all DDDs per person per month. Similarly, number of visits to general practitioners (GPs), psychiatrists and Emergency Rooms (ERs) were summed per person per month. Three-way repeated measures ANOVA was used, including the variables time (12 months), region (north/other) and study group.

Results.

During the war there was a decline in GP visits among people from the general population and people ‘at risk’ for depression/anxiety who resided in northern Israel that was not paralleled among controls. Similarly, in all three study groups, there was a decline in the number of psychiatrist visits during the war among people from northern Israel which did not occur to the same extent in the control group. There were no changes in ER visits or use of psychiatric medication that could be attributed to the war.

Conclusions.

There is less utilisation of community services at times of war among exposed populations, and there is neither evident compensation in use of emergency services, nor any compensation after the war. This may suggest that if there is an efficient medical and mental health infrastructure, people with or without psychiatric risk factors can tolerate a few weeks of a mass stress event, with no need to expand medical service utilisation. However, service utilisation at times of war may be confounded by other variables and may not serve as a direct measure of increased stress.
Risk Perception in Pregnancy
Authors: Robinson Monique , Pennell Craig E. , McLean Neil J. , Tearne Jessica E. , Oddy Wendy H. , Newnham John P.
Published: January 2015

Despite huge advances in obstetric management and technology in recent decades, there has not been an accompanying decrease in patients’ perception of risk during pregnancy. The aim of this paper is to examine the context of risk perception in pregnancy and what practitioners can do to manage it. The modern pregnancy may induce a heightened perception of risk due to increased prenatal testing and surveillance, medico-legal complexity, fertility treatment, and the increasing use of the internet and social media as a source of information. The consequences of an inflated perception of risk during pregnancy include stress, anxiety, and depression, and these issues may have long-lasting implications for patients, their babies, and their families. There are numerous resilience and vulnerability factors that can help care providers identify those who may be predisposed to increased risk perception in pregnancy, and there is a role for both obstetric care providers and psychologists engaged in obstetric settings to manage and reduce risk perception in patients where possible. Ultimately, the medical management of risk during pregnancy can be complex but a thorough understanding of the social and emotional context can assist providers to support their patients through both high- and low-risk pregnancy and birth.
Socially Shared Regulation of Learning: A Review
Authors: Panadero Ernesto , Järvelä Sanna
Published: January 2015

Abstract. Socially shared regulation of learning (SSRL) has been recognized as a new and growing field in the framework of self-regulated learning theory in the past decade. In the present review, we examine the empirical evidence to support such a phenomenon. A total of 17 articles addressing SSRL were identified, 13 of which presented empirical evidence. Through a narrative review it could be concluded that there is enough data to maintain the existence of SSRL in comparison to other social regulation (e.g., co-regulation). It was found that most of the SSRL research has focused on characterizing phenomena through the use of mixed methods through qualitative data, mostly video-recorded observation data. Also, SSRL seems to contribute to students’ performance. Finally, the article discusses the need for the field to move forward, exploring the best conditions to promote SSRL, clarifying whether SSRL is always the optimal form of collaboration, and identifying more aspects of groups’ characteristics.
Ambient seafloor noise excited by earthquakes in the Nankai subduction zone
Authors: Tonegawa Takashi , Fukao Yoshio , Takahashi Tsutomu , Obana Koichiro , Kodaira Shuichi , Kaneda Yoshiyuki
Published: January 2015

Excitations of seismic background noises are mostly related to fluid disturbances in the atmosphere, ocean and the solid Earth. Earthquakes have not been considered as a stationary excitation source because they occur intermittently. Here we report that acoustic-coupled Rayleigh waves (at 0.7–2.0 Hz) travelling in the ocean and marine sediments, retrieved by correlating ambient noise on a hydrophone array deployed through a shallow to deep seafloor (100–4,800 m) across the Nankai Trough, Japan, are incessantly excited by nearby small earthquakes. The observed cross-correlation functions and 2D numerical simulations for wave propagation through a laterally heterogeneous ocean–crust system show that, in a subduction zone, energetic wave sources are located primarily under the seafloor in directions consistent with nearby seismicity, and secondarily in the ocean. Short-period background noise in the ocean–crust system in the Nankai subduction zone is mainly attributed to ocean-acoustic Rayleigh waves of earthquake origin.
Macrotene chromosomes provide insights to a new mechanism of high-order gene amplification in eukaryotes
Authors: Thierry Agnès , Khanna Varun , Créno Sophie , Lafontaine Ingrid , Ma Laurence , Bouchier Christiane , Dujon Bernard
Published: January 2015

Copy number variation of chromosomal segments is now recognized as a major source of genetic polymorphism within natural populations of eukaryotes, as well as a possible cause of genetic diseases in humans, including cancer, but its molecular bases remain incompletely understood. In the baker’s yeast Saccharomyces cerevisiae, a variety of low-order amplifications (segmental duplications) were observed after adaptation to limiting environmental conditions or recovery from gene dosage imbalance, and interpreted in terms of replication-based mechanisms associated or not with homologous recombination. Here we show the emergence of novel high-order amplification structures, with corresponding overexpression of embedded genes, during evolution under favourable growth conditions of severely unfit yeast cells bearing genetically disabled genomes. Such events form massively extended chromosomes, which we propose to call macrotene, whose characteristics suggest the products of intrachromosomal rolling-circle type of replication structures, probably initiated by increased accidental template switches under important cellular stress conditions.
Strong enhancement of photoresponsivity with shrinking the electrodes spacing in few layer GaSe photodetectors

Published: January 2015

A critical challenge for the integration of optoelectronics is that photodetectors have relatively poor sensitivities at the nanometer scale. Generally, a large electrodes spacing in photodetectors is required to absorb sufficient light to maintain high photoresponsivity and reduce the dark current. However, this will limit the optoelectronic integration density. Through spatially resolved photocurrent investigation, we find that the photocurrent in metal-semiconductor-metal (MSM) photodetectors based on layered GaSe is mainly generated from the region close to the metal-GaSe interface with higher electrical potential. The photoresponsivity monotonically increases with shrinking the spacing distance before the direct tunneling happens, which was significantly enhanced up to 5,000 AW−1 for the bottom Ti/Au contacted device. It is more than 1,700-fold improvement over the previously reported results. The response time of the Ti/Au contacted devices is about 10–20 ms and reduced down to 270 μs for the devices with single layer graphene as metallic electrodes. A theoretical model has been developed to well explain the photoresponsivity for these two types of device configurations. Our findings realize reducing the size and improving the performance of 2D semiconductor based MSM photodetectors simultaneously, which could pave the way for future high density integration of optoelectronics with high performances.
The short-chain fatty acid receptor GPR43 is transcriptionally regulated by XBP1 in human monocytes
Authors: Ang Zhiwei , Er Jun Zhi , Ding Jeak Ling
Published: January 2015

G-protein coupled receptor 43 (GPR43) recognizes short chain fatty acids and is implicated in obesity, colitis, asthma and arthritis. Here, we present the first full characterization of the GPR43 promoter and 5′-UTR. 5′-RACE of the GPR43 transcript identified the transcription start site (TSS) and a 124 bp 5′-UTR followed by a 1335 bp intron upstream of the ATG start codon. The sequence spanning -4560 to +68 bp relative to the GPR43 TSS was found to contain strong promoter activity, increasing luciferase reporter expression by >100-fold in U937 monocytes. Stepwise deletions further narrowed the putative GPR43 promoter (−451 to +68). Site-directed mutagenesis identified XBP1 as a core cis element, the mutation of which abrogated transcriptional activity. Mutations of predicted CREB, CHOP, NFAT and STAT5 binding sites, partially reduced promoter activity. ChIP assays confirmed the binding of XBP1 to the endogenous GPR43 promoter. Consistently, GPR43 expression is reduced in monocytes upon siRNA-knockdown of XBP1, while A549 cells overexpressing XBP1 displayed elevated GPR43 levels. Based on its ability to activate XBP1, we predicted and confirmed that TNFα induces GPR43 expression in human monocytes. Altogether, our findings form the basis for strategic modulation of GPR43 expression, with a view to regulate GPR43-associated diseases.
Rationally Designed Peptidomimetic Modulators of Aβ Toxicity in Alzheimer's Disease
Authors: Rajasekhar K. , Suresh S. N. , Manjithaya Ravi , Govindaraju T.
Published: January 2015

Alzheimer's disease is one of the devastating illnesses mankind is facing in the 21st century. The main pathogenic event in Alzheimer's disease is believed to be the aggregation of the β-amyloid (Aβ) peptides into toxic aggregates. Molecules that interfere with this process may act as therapeutic agents for the treatment of the disease. Use of recognition unit based peptidomimetics as inhibitors are a promising approach, as they exhibit greater protease stability compared to natural peptides. Here, we present peptidomimetic inhibitors of Aβ aggregation designed based on the KLVFF (P1) sequence that is known to bind Aβ aggregates. We improved inhibition efficiency of P1 by introducing multiple hydrogen bond donor-acceptor moieties (thymine/barbiturate) at the N-terminal (P2 and P3) and blood serum stability by modifying the backbone by incorporating sarcosine (N-methylglycine) units at alternate positions (P4 and P5). The peptidomimetics showed moderate to good activity in both inhibition and dissolution of Aβ aggregates as depicted by thioflavin assay, circular dichroism (CD) measurements and microscopy (TEM). The activity of P4 and P5 were studied in a yeast cell model showing Aβ toxicity. P4 and P5 could rescue yeast cells from Aβ toxicity and Aβ aggregates were cleared by the process of autophagy.
Highlighting nonlinear patterns in population genetics datasets
Authors: Alanis-Lobato Gregorio , Cannistraci Carlo Vittorio , Eriksson Anders , Manica Andrea , Ravasi Timothy
Published: January 2015

Detecting structure in population genetics and case-control studies is important, as it exposes phenomena such as ecoclines, admixture and stratification. Principal Component Analysis (PCA) is a linear dimension-reduction technique commonly used for this purpose, but it struggles to reveal complex, nonlinear data patterns. In this paper we introduce non-centred Minimum Curvilinear Embedding (ncMCE), a nonlinear method to overcome this problem. Our analyses show that ncMCE can separate individuals into ethnic groups in cases in which PCA fails to reveal any clear structure. This increased discrimination power arises from ncMCE's ability to better capture the phylogenetic signal in the samples, whereas PCA better reflects their geographic relation. We also demonstrate how ncMCE can discover interesting patterns, even when the data has been poorly pre-processed. The juxtaposition of PCA and ncMCE visualisations provides a new standard of analysis with utility for discovering and validating significant linear/nonlinear complementary patterns in genetic data.

IUPAC-NIST Solubility Data Series. 100. Rare Earth Metal Fluorides in Water and Aqueous Systems. Part 2. Light Lanthanides (Ce–Eu)
Authors: Mioduski Tomasz , Gumiński Cezary , Zeng Dewen
Published: January 2015

This is the second part of the volume devoted to the evaluation of experimental solubility data for rare earth metal (REM) fluorides in water as well as in aqueous ternary and multicomponent systems. Fluorides of Ce, Pr, Nd, Pm, Sm, and Eu (so-called light lanthanides), as the main solutes, are covered in the present part, which has thorough coverage of the experimental literature through the end of 2012. The experimentally unknown solubility value for PmF3 in water was predicted by an interpolation of the solubility values for NdF3 and SmF3 at 298 K. General features of the systems, such as the nature of the equilibrium solid phases, solubility as a function of temperature, influence of ionic strength, pH, mixed solvent medium on the solubility, quality of the solubility results, and solubility as a function of REM atomic number, have already been presented in Part 1 of the volume.
