Engineered Peptide Repairs Defective Adhesive–Dentin Interface
Authors: Ye Qiang , Spencer Paulette , Yuca Esra , Tamerler Candan 
Published: February 2017

Failure of dental composite restorations is primarily due to recurrent decay at the tooth–composite interface. At this interface, the adhesive and its bond with dentin is the barrier between the restored tooth and the oral environment. In vivo degradation of the bond formed at the adhesive/dentin (a/d) interface follows a cascade of events leading to weakening of the composite restoration. Here, a peptide‐based approach is developed to mineralize deficient dentin matrices at the a/d interface. Peptides that have an inherent capacity to self‐assemble on dentin and to induce calcium–phosphate remineralization are anchored at the interface. Distribution of adhesive, collagen, and mineral is analyzed using micro‐Raman spectroscopy and fluorescence microscopy. The analysis demonstrates remineralization of the deficient dentin matrices achieved throughout the interface with homogeneous distribution of mineral. The peptide‐based remineralization demonstrated here can be an enabling technology to design integrated biomaterial–tissue interfaces.

ScopeSystemic lupus erythematosus (SLE) is a chronic multiorgan autoimmune disease characterized by immune deregulation, which involves altered T‐cell response and imbalance of cytokine production. The phenolic fraction (PE) of extra virgin olive oil (EVOO) possesses anti‐inflammatory and immunomodulatory properties and exerts preventive effects in murine models of immune‐inflammatory diseases, such as SLE. The present study was designed to determine the in vitro effects of the PE from EVOO on peripheral blood mononuclear cells (PBMC) from inactive patients with SLE and healthy donors.Methods and resultsT‐cell phenotype was investigated by flow cytometry, cytokine levels were determined by ELISA, and protein expression was detected by Western blot. The PE of EVOO decreased the frequency of CD69+cells and the secretion of IFN‐γ, TNF‐α, IL‐6, IL‐1β, and IL‐10. Moreover, PE increased the expression of I‐kappa‐B‐α and decreased extracellular signal regulated kinase phosphorylation on PBMC from patients with SLE and healthy donors.ConclusionPE modulates cytokine production and attenuates induced T‐cell activation, probably through NF‐κB signaling pathway, providing the first evidence that PE from EVOO has an anti‐inflammatory and immunomodulatory role in SLE patients and it might therefore be considered as a dietary complement in SLE management
Using Social Enterprises for Social Policy in South Korea: Do Funding and Management Affect Social and Economic Performance?
Authors: Kim Tae Hyung , Moon M. Jae 
Published: February 2017

SummaryThis study examines the way the South Korean government utilizes social enterprises as a policy alternative to promote employment and provide social services for the socially disadvantaged. As an example of “capable policy design” characterized as high levels of instrumentality and government capacity, this study focuses more specifically on the social and economic performance of Korean social enterprises. Using the Korea Social Enterprise Data, this study conducts an empirical analysis to identify how government subsidies and management quality affect the social and economic performance of social enterprises. The results show that government subsidies partially contribute to the enhancement of the enterprises' social performance and economic performance. There are mixed results regarding the effect of management quality on the social and economic performance of social enterprises. The results also suggest that general donations from citizens along with government subsidies help social enterprises pursue social performance particularly in employment of socially disadvantaged people, while corporate donations promote the provision of social services. This suggests that government subsidy is an important instrument in the birth and growth of social enterprises as well as the social and economic performance of social enterprises but should be complemented by corporate and general donations to sustain both social and economic performance in the long run.

Improving Policy Design and Building Capacity in Local Experiments: Equalization of Public Service in China's Urban‐rural Integration Pilot
Authors: Qian Jiwei 
Published: February 2017

SummaryPolicy design is important, and high policy capacity is necessary for social policy‐making. Local experimentation is helpful in building capacity and therefore supporting policy design. Since 2007, China has initiated an ‘urban–rural integration’ reform to equalize the access to public services between urban and rural residents. This paper uses the Chongqing urban–rural integration pilot as a case to illustrate how and to what degree a local experiment can be useful in building policy capacity and improving policy design. Regarding the Chongqing pilot, policy capacity in administration and governance has been improved through mechanisms including coordinating government departments through a small leading group led by local leaders as well as incentivizing bureaucrats by linking quantified policy targets with officials' performance evaluations. Equalizing access to public services by facilitating the mobility of factors, including labour, credit, and land, is the key rationale in the policy design of the Chongqing pilot. Under this policy design, fiscal capacity has been enhanced significantly, and policy initiatives have been financed with an improved fiscal capacity. At the same time, however, unintended consequences in the Chongqing pilot have been observed, including misallocation of resources and underdevelopment of some dimensions of policy capacity. Institutional reforms might also have been undermined. Copyright © 2017 John Wiley & Sons, Ltd.
Third Bosphorus Bridge – A masterpiece of sculptural engineering
Authors: Klein Jean‐Francois 
Published: February 2017

AbstractThe recently completed new connection between Europe and Asia, the Third Bosphorus Bridge (Yavuz Sultan Selim Bridge) has been immediately recognized as an iconic and new landmark of Istanbul region. The reason is not only the location which makes the crossing a dramatic scenery and a real experience, but of course the structure itself and also its history. Never such an audacious and extreme structure has been built like this, following a strict and severe red and straight line starting from the day of the decision to award the contract to the ICA joint Venture (Içtas/Astaldi) on the base of a project considered by the authorities as the one bringing the most satisfactory answer to their requirements, a project worked out during a competition period of finally eight weeks. And the requirements were very high, exactly at the level prerequisite for such an important structure considering its serviceability, but also its geopolitical context and its economic importance.
Anmerkungen zum Stabilitätsnachweis längsversteifter Platten unter biaxialem Druck
Authors: Hertle Robert , Mensinger Martin , Ndogmo Joseph , Köberlin Thomas 
Published: February 2017

AbstractMit Hilfe eines Ritzschen Näherungsansatzes wird das Problem des Gesamtfeldbeulens unter biaxialem Druck diskutiert. Es zeigt sich, dass bei einer Begrenzung der Durchbiegung der Längssteifen, wie sie in Abschnitt 9.2. der DIN EN 1993‐1‐5:2010 für Quersteifen gefordert wird, der Nachweis des Gesamtfeldbeulens nach Gl. 10.5 der Norm durch den Nachweis des maßgebenden Einzelfelds und den Stabilitätsnachweis der Längssteifen unter Berücksichtigung der zusätzlichen Abtriebskräfte aus Querdruck ersetzt werden kann. Umgekehrt kann, wie am Beispiel des Beulfelds einer Bodenplatte beim Taktschieben gezeigt wird, der Gesamtfeldbeulnachweis nach Gl. 10.5 der DIN EN 1993‐1‐5:2010 den Stabilitätsnachweis der Längssteifen nicht ersetzen. Am Beispiel des Gesamtfeldbeulens eines Stegblechs einer Brücke wird gezeigt, dass der Nachweis nach Gl. 10.5 in manchen Fällen auch zu unwirtschaftlichen Ergebnissen führen kann.

Published: February 2017

AbstractDie Elsterbrücke Osendorf ist die erste Brücke in Deutschland, die in Verbundfertigteil‐Bauweise mit Walzträgern in Beton (VFT‐WIB) mit feuerverzinkter Stahltragstruktur ausgeführt wurde. Auf Grundlage von Forschungsprojekten konnte die Ermüdungsfestigkeit von dynamisch beanspruchten Stahlbauteilen beurteilt werden. Die gewählte Bauweise bietet sich in ihrer Konstruktionsart für eine Feuerverzinkung an. Ihre externe Bewehrung aus halbierten Walzträgern ist arm an Eigenspannungen und mit Längen bis 16 m leicht in der Verzinkung zu handhaben. Im Projekt Brücke Osendorf zeigte sich die Wirtschaftlichkeit der Feuerverzinkung im Hinblick auf Qualität, Kosten und Unterhalt.
Plates with incompatible prestrain of high order

Published: February 2017

We study the elastic behaviour of incompatibly prestrained thin plates of thickness

whose internal energy

E^{h}

is governed by an imposed three-dimensional smooth Riemann metric

converges to a finite value

c

when the metric

G

restricted to the midsurface has a sufficiently regular immersion, namely

W^{2,2}(\omega ,\mathbb{R}^{3})

. The obtained limit model generalizes the bending (Kirhchoff) model of Euclidean elasticity. In the present paper, we deal with the case when

0

. Then, equivalently, three independent entries of the three-dimensional Riemann curvature tensor associated with

G

are null. We prove that, in such regime, necessarily

\mathrm{\inf }⁡E^{h} \leq Ch^{4}

. We identify the

-limit of the scaled energies

h^{−4}E^{h}

and show that it consists of a von Kármán-like energy. The unknowns in this energy are the first order incremental displacements with respect to the deformation defined by the bending model and the second order tangential strains. In addition, we prove that when

\mathrm{\inf }⁡h^{−4}E^{h}\rightarrow 0

, then

G

is realizable and hence

\mathrm{\min }⁡E^{h} = 0

for every

Abstract
The discovery of Tethyan and Boreal fossils in Bathonian deposits of the Sokur section in the vicinity of Saratov (Central Russia) reopened the possibility of direct correlation of the Bathonian sections in different paleobiogeographic provinces, which require further integrated studies involving both paleontological (based on different groups of fauna) and physicochemical (paleomagnetic and isotope-geochemical) methods. Stable carbon isotope data for belemnite (Cylindroteuthididae) rostra from the Sokur section show that the Subboreal Oraniceras besnosovi Zone and Boreal Arcticoceras harlandi Subzone are correlated with the Zigzag Zone of the standard scale, whereas the Boreal A. ishmae Subzone can be correlated completely or, even partly, with the Tenuiplicatus Zone. We identified equivalents of chrons of the geomagnetic polarity time scale (GPTS): e-Bath N, m-Bath R, and lt-Bath N, corresponding to the Lower–Middle Bathonian and, possibly, lowermost Upper Bathonian.
Diagenetic transformation of organic matter in the Holocene sediments of the Black Sea: pyrolysis data
Authors: Melenevskii V.N. , Saraev S.V. , Kostyreva E.A. , Kashirtsev V.A. 
Published: February 2017

Abstract
The article presents the results of pyrolysis (Rock-Eval) and pyrolysis–gas chromatography–mass spectrometry analysis of organic matter (OM) in the Holocene sediments of the Black Sea. The studied samples represent two parts of the sedimentary column: coccolith ooze with 2.8% Corg at the top and sapropels oozes with 8.5% Corg at the bottom. The deposition of Holocene sediments was inferred to take place under euxinic conditions, which are more favorable for organic-matter preservation and sapropel deposition during the Old Black Sea stage. The results show that the modern processes of microbially mediated methane oxidation in the Old Black Sea oozes are interpreted as the main cause of their apparently lower degree of diagenetic transformation as compared to that of coccolith oozes.
National Security or Privacy: A Second Thought on the DNC
Hack
Authors: Jun Sung-In 
Published: February 2017

The recent U.S. Democratic National Committee (DNC) hack raises several difficult
questions in the fields of cybersecurity and privacy. Obviously, this was first and
foremost a matter of security in that the hack likely involved a
foreign government attempting to intervene in a
presidential election process with the possible motive of influencing its outcome.
From another perspective, however, the incident was also a matter of
privacy, in that the fundamental motive of the DNC hack was to
reveal “information that the victim wants to keep private” and to influence its
future decision through the compromise of privacy.
Costinuculana magharensisn. gen. n. sp. (Bivalvia, Nuculanidae) from the Middle Jurassic of Gebel Maghara, North Sinai, Egypt
Authors: Ayoub-Hannaa Wagih S. , Abdelhady Ahmad A. , Fürsich Franz T. 
Published: February 2017

AbstractThe nuculanid bivalveCostinuculana magharensisnew genus new species is described from the middle to upper Bathonian Kehailia Formation of Gebel Maghara, North Sinai, Egypt.Costinuculanadiffers from other genera of the family Nuculanidae by the presence of opisthocline ribs along the rostrum. These ribs are variable in shape and size, straight to folded posteriorly, bifurcate ventrally and occasionally postero-dorsally, and cover an area~45% of the total valve length from the posterior end. The life position ofC.magharensisn. gen. n. sp. is reconstructed on the basis of a functional interpretation of its morphology and by comparison with closely related Recent forms. The asymmetrical commarginal ribs facilitated the burrowing process. The posterior oblique ribs are asymmetrical in cross-section with a steeply concave side in the burrowing direction and slightly convex side in the opposite direction. They probably kept the bivalve in a stable position once the desired depth had been reached. The thick oblique ribs probably also increased the strength of the rostrum and offered resistance against durophagous predators, being presumably partly exposed above the sediment-water interface. Based on the associated fauna,Costinuculanan. gen. lived in a low-energy environment characterized by a fine-grained, soft substrate.
Toward a “Truly Indigenous Theatre”: Sylvia Wynter Adapts Federico García Lorca
Authors: Owens Imani D. 
Published: February 2017

AbstractThis article recuperates the creative work of Jamaican cultural theorist Sylvia Wynter, arguing that her activities as a dramatist and translator constitute foundational efforts to imagine an emerging postcolonial reading public. The article considers Wynter’s heretofore-neglected adaptation of Federico García Lorca’sLa Casa De Bernarda Alba. The play appears in the newly foundedJamaica Journalin 1968, alongside an essay theorizing adaptation, production, and sets. Adaptation, for Wynter, is strategy of postcolonial reading that requires carefulreinterpretation, an emphasis on historicity, and sensitivity to the imperatives of theatricality. The play evidences Wynter’s concern with the politics and poetics of translation, a transformative act that exemplifies the process ofindigenizationtheorized in her later works. Wynter transforms Lorca’s original, “transposing” it to a Jamaican setting and adding dialogue and content to craft a scathing meditation on the legacies of colonialism. Published shortly after Jamaican independence in 1962, this play imagines a “truly indigenous theatre” as central to the formation a postcolonial public.

AbstractGlycaemic index (GI) and glycaemic load (GL) are indicators of dietary carbohydrate quantity and quality and have been associated with increased risk of certain cancers and type 2 diabetes. Insulin resistance has been associated with increased melanoma risk. However, GI and GL have not been investigated for melanoma. We present the first study to examine the possible association of GI and GL with melanoma risk. We carried out a population-based, case–control study involving 380 incident cases of cutaneous melanoma and 719 age- and sex-matched controls in a northern Italian region. Dietary GI and GL were computed for each subject using data from a self-administered, semi-quantitative food frequency questionnaire. We computed the odds ratio (OR) for melanoma according to quintiles of distribution of GL and GL among controls. A direct association between melanoma risk and GL emerged in females (OR 2·38; 95 % CI 1·25, 4·52 for the highest v. the lowest quintile of GL score, Pfor trend 0·070) but not in males. The association in females persisted in the multivariable analysis after adjusting for several potential confounders. There was no evidence of an association between GI and melanoma risk. GL might be associated with melanoma risk in females.
The effects of vitamin and mineral supplementation on symptoms of schizophrenia: a systematic review and meta-analysis

Published: February 2017

BackgroundWhen used as an adjunctive with antipsychotics, certain vitamins and minerals may be effective for improving symptomatic outcomes of schizophrenia, by restoring nutritional deficits, reducing oxidative stress, or modulating neurological pathways.MethodWe conducted a systematic review of all randomized controlled trials (RCTs) reporting effects of vitamin and/or mineral supplements on psychiatric symptoms in people with schizophrenia. Random-effects meta-analyses were used to calculate the standardized mean difference between nutrient and placebo treatments.ResultsAn electronic database search in July 2016 identified 18 eligible RCTs, with outcome data for 832 patients. Pooled effects showed that vitamin B supplementation (including B6, B8 and B12) reduced psychiatric symptoms significantly more than control conditions [g= 0.508, 95% confidence interval (CI) 0.01–1.01,p= 0.047,I2= 72.3%]. Similar effects were observed among vitamin B RCTs which used intention-to-treat analyses (g= 0.734, 95% CI 0.00–1.49,p= 0.051). However, no effects of B vitamins were observed in individual domains of positive and negative symptoms (bothp> 0.1). Meta-regression analyses showed that shorter illness duration was associated with greater vitamin B effectiveness (p= 0.001). There were no overall effects from antioxidant vitamins, inositol or dietary minerals on psychiatric symptoms.ConclusionsThere is preliminary evidence that certain vitamin and mineral supplements may reduce psychiatric symptoms in some people with schizophrenia. Further research is needed to examine how the benefits of supplementation relate to nutrient deficits and the impact upon underlying neurobiological pathways, in order to establish optimal nutrient formulations for improving clinical outcomes in this population. Future studies should also explore the effects of combining beneficial nutrients within multi-nutrient formulas.

Colonial imprints: settler-colonialism as a fundamental feature of Israeli constitutional law
Authors: Masri Mazen 
Published: February 2017

AbstractMany constitutional questions in Israel are dealt with through the lens of the nation-state paradigm where the state is constitutionally associated with an ethnically and religiously defined majority group. Thus, many of the challenges that face Israeli society and the legal system are often presented as a result of an exceptionally antagonistic majority–minority relationship in a nation-state. This paper offers a novel way of analysing the Israeli constitutional regime using the framework of settler-colonialism. It argues that adding the settler-colonial lens will help better understand many features of Israeli constitutional law. Drawing on theoretical frameworks developed by theorists of colonialism, the paper explores a number of foundational aspects of Israeli constitutional law and demonstrates how they were shaped, and continue to be shaped, by settler-colonialism. The paper argues that settler-colonialism is one of the central features that animate Israeli constitutional law.
