Growing Extraordinary Writers: Leadership Decisions to Raise the Level of Writing Across a School and a District
Authors: Calkins Lucy , Ehrenworth Mary 
Published: June 2016

AbstractIncreasingly, school leaders recognize the need for writing instruction to become a schoolwide priority. The writers’ workshop approach that was popularized 30 years ago is still relevant; it is still important to give students protected time to write, opportunities to address topics and audiences that matter, and timely feedback. Recent research emphasizes that students also benefit from explicit instruction in the craft and structure of specific types of writing and from working toward clear images of good writing. Teachers can accelerate students’ growth by developing shared expectations for good writing and a common language for talking about writing. Clear goals are important for teachers, too. Shared knowledge of effective writing instruction and ways to track writing growth over time lift the level of instruction across a school, supporting teacher‐to‐teacher collaboration. When student growth is regarded as feedback to teachers on their teaching, assessment‐based instruction helps schools participate in continuous improvement.
A fly's view of neuronal remodeling
Authors: Yaniv Shiri P. , Schuldiner Oren 
Published: June 2016

Developmental neuronal remodeling is a crucial step in sculpting the final and mature brain connectivity in both vertebrates and invertebrates. Remodeling includes degenerative events, such as neurite pruning, that may be followed by regeneration to form novel connections during normal development. Drosophila provides an excellent model to study both steps of remodeling since its nervous system undergoes massive and stereotypic remodeling during metamorphosis. Although pruning has been widely studied, our knowledge of the molecular and cellular mechanisms is far from complete. Our understanding of the processes underlying regrowth is even more fragmentary. In this review, we discuss recent progress by focusing on three groups of neurons that undergo stereotypic pruning and regrowth during metamorphosis, the mushroom body γ neurons, the dendritic arborization neurons and the crustacean cardioactive peptide peptidergic neurons. By comparing and contrasting the mechanisms involved in remodeling of these three neuronal types, we highlight the common themes and differences as well as raise key questions for future investigation in the field.

Isogeometric based framework for aeroelastic wind turbine blade analysis
Authors: Ferede Etana , Abdalla Mostafa M. , van Bussel Gerard J. W. 
Published: June 2016

AbstractA framework based on isogeometric analysis is presented for parametrizing a wind turbine rotor blade and evaluating its response. The framework consists of a multi‐fidelity approach for wind turbine rotor analysis. The aeroelastic loads are determined using a low‐fidelity model. The model is based on isogeometric approach to model both the structural and aerodynamic properties. The structural deformations are solved using an isogeometric formulation of geometrically exact 3D beam theory. The aerodynamic loads are calculated using a standard Blade Element Momentum(BEM) theory. Moreover, the aerodynamic loads calculated using BEM theory are modified to account for the change in the blade shape due to blade deformation. The aeroelastic loads are applied in finite element solver Nastran, and both the stress response and buckling response are extracted. Furthermore, the capabilities of Nastran are extended such that design dependent loads can be applied, resulting in correct aeroelastic sensitivities of Nastran responses, making this framework suitable for optimization. The framework is verified against results from the commercial codes FAST and GH Bladed, using the NREL 61.5m rotor blade as a baseline for comparison, showing good agreement.

Global stability of a class of futile cycles
Authors: Rao Shodhan 
Published: June 2016

Abstract
In this paper, we prove the global asymptotic stability of a class of mass action futile cycle networks which includes a model of processive multisite phosphorylation networks. The proof consists of two parts. In the first part, we prove that there is a unique equilibrium in every positive compatibility class. In the second part, we make use of a piecewise linear in rates Lyapunov function in order to prove the global asymptotic stability of the unique equilibrium corresponding to a given initial concentration vector. The main novelty of the paper is the use of a simple algebraic approach based on the intermediate value property of continuous functions in order to prove the uniqueness of equilibrium in every positive compatibility class.
A flow-to-equity approach to coordinate supply chain network planning and financial planning with annual cash outflows to an institutional investor
Authors: Steinrücke Martin , Albrecht Wolfgang 
Published: June 2016

AbstractA common side effect of cross-linked global economies is that well-positioned middle class companies are acquired by institutional investors, which formulate unreasonable return expectations in many cases. As a consequence, the resulting payouts are often not in line with business operations so that even world market leaders get into trouble or close down. In this context, we consider the case of a sanitary company, which had to manage the described situation after a business takeover. In order to coordinate the annual cash outflows to the investor with intra-organizational supply chain planning and financial planning, we propose a mixed-integer non-linear programming model that is based on the flow-to-equity discounted cash flow method. The objective is to maximize the present value of equity while determining annual cash outflows to the institutional investor during his engagement. As the decisions of the investor during his engagement influence possible operations of the company after his engagement, the residual value of equity (that influences the selling price) is taken into account. The modeling is based on cash flow series, which result from supply chain operations and restructuring on the one hand, and from financial transactions on the other. Financing is characterized by interest rates depending on the time period the credit starts, the credit period, the debt limit of the company and the current total debt. As the latter is a result of the optimization, non-linearity arises. Nevertheless, both the expected demand scenario and further randomly generated demand scenarios of the sanitary company could be solved to the optimum with the commercial optimization package GAMS 23.8/SCIP 2.1.1 within acceptable computation times, if capacity profiles are assigned to the locations to depict feasible and/or preferred capacity developments.
FRAGMENTS OF FREGE’SGRUNDGESETZEAND GÖDEL’S CONSTRUCTIBLE UNIVERSE
Authors: WALSH SEAN 
Published: June 2016

AbstractFrege’sGrundgesetzewas one of the 19th century forerunners to contemporary set theory which was plagued by the Russell paradox. In recent years, it has been shown that subsystems of theGrundgesetzeformed by restricting the comprehension schema are consistent. One aim of this paper is to ascertain how much set theory can be developed within these consistent fragments of theGrundgesetze, and our main theorem (Theorem 2.9) shows that there is a model of a fragment of theGrundgesetzewhich defines a model of all the axioms of Zermelo–Fraenkel set theory with the exception of the power set axiom. The proof of this result appeals to Gödel’s constructible universe of sets and to Kripke and Platek’s idea of the projectum, as well as to a weak version of uniformization (which does not involve knowledge of Jensen’s fine structure theory). The axioms of theGrundgesetzeare examples ofabstraction principles, and the other primary aim of this paper is to articulate a sufficient condition for the consistency of abstraction principles with limited amounts of comprehension (Theorem 3.5). As an application, we resolve an analogue of the joint consistency problem in the predicative setting.
A RAMSEY THEOREM ON SEMIGROUPS AND A GENERAL VAN DER CORPUT LEMMA
Authors: TSERUNYAN ANUSH 
Published: June 2016

AbstractA major theme in arithmetic combinatorics is proving multiple recurrence results on semigroups (such as Szemerédi’s theorem) and this can often be done using methods of ergodic Ramsey theory. What usually lies at the heart of such proofs is that, for actions of semigroups, a certain kind of one recurrence (mixing along a filter) amplifies itself to multiple recurrence. This amplification is proved using a so-called van der Corput difference lemma for a suitable filter on the semigroup. Particular instances of this lemma (for concrete filters) have been proven before (by Furstenberg, Bergelson–McCutcheon, and others), with a somewhat different proof in each case. We define a notion of differentiation for subsets of semigroups and isolate the class of filters that respect this notion. The filters in this class (call them ∂-filters) include all those for which the van der Corput lemma was known, and our main result is a van der Corput lemma for ∂-filters, which thus generalizes all its previous instances. This is done via proving a Ramsey theorem for graphs on the semigroup with edges between the semigroup elements labeled by their ratios.

We shall prove that, this abstract formulation is equivalent to the direct irreducibility for atomic complete modular ortholattices.
The Attalid victory at Magnesia on a lost plaque from Pergamon
Authors: Taylor Michael J. 
Published: June 2016

AbstractThis article explores the battle scene on a small bronze plaque recovered during the 19th-century excavation of Pergamon, initially published in 1913 and subsequently lost. It argues that the most likely identification of the scene is the Battle of Magnesia, fought in 190 BC. The scene features Attalid cavalry riding to the rescue of distressed Roman legionaries, both fighting in opposition to Antiochus the Great's heavy phalanx and Gallic cavalry. The heroics of the Attalid cavalry are central to the scene, and likely reflect a courtly narrative that gave Eumenes II and his small contingent outsized credit for the joint victory.
New inscriptions from the Choria Considiana: Çalçak Roman necropolis
Authors: Güney Hale 
Published: June 2016

AbstractThis paper presents the initial results of an epigraphic survey of a Roman imperial estate, carried out in 2014 in northern Choria Considiana, today encompassing the area of Mihalıççık in Eskişehir, located between the Sakarya (Sangarios) river to the north and the Porsuk (Tembris) river to the south. The paper focuses on ten funerary inscriptions found in situ in the Çalçak Roman necropolis, 4km distant from Dinek village in Mihalıççık. All these inscriptions, found on the northern edge of the Choria Considiana, contain information relating to the social and economic status of the inhabitants of the estate, and also offer evidence about stone quarries and stonemasonry in the region. The paper begins with a presentation of the historical geography of the region, and then evaluates the new inscriptions against the existing evidence about the Choria Considiana with reference to the social and economic infrastructure of the area; important questions about the social, economic and cultural life of the region are posed. The article concludes with a catalogue of the inscriptions.
Pagan angels in Roman Asia Minor: revisiting the epigraphic evidence
Authors: Horsley G.H.R. , Luxford Jean M. 
Published: June 2016

AbstractFranz Cumont's influential article on pagan angels in Revue de l’histoire des religions, published just over a century ago in 1915, remains the point de départ for work on that subject. The present essay offers a brief evaluation of some of its features, and then concentrates on Greek epigraphic evidence from Asia Minor in the Roman imperial period. Most of these texts were not published when Cumont wrote, or else he treated them briefly since his focus lay largely on ancient philosophical discussions about angeloi by both insiders and outsiders to the Christian movement; and geographically he ranged more widely than we have chosen to do. The main aim of the present essay, however, is to test the widely-accepted hypothesis of A.R.R. Sheppard (1980/1981) that Jewish influence on pagan notions of angeloi is visible in these inscriptions even though that influence was applied by non-Jews in a confused manner.
A late antique ceramic workshop complex: evidence for workshop organisation at Sagalassos (southwest Turkey)
Authors: Murphy Elizabeth A. , Poblome Jeroen 
Published: June 2016

AbstractSites of ceramic production have been discovered throughout the area that was once the Roman Empire; as a result, it is becoming increasingly clear that this industry was, in the Roman and late antique worlds, organised in numerous ways. In consideration of the organisational diversity in ceramic production attested during the period, this article presents some of the findings from the excavations of a late antique complex of ceramic workshops at the site of Sagalassos in order to consider archaeological evidence in terms of, not only the organisation of the manufacturing process, but also structures of workshop decision-making. Several lines of archaeological evidence are outlined, and argue for a model of independent work units integrated into a larger organisational structure of decision-making, and possibly even ownership, across the complex. In addition, the motivation to invest in a multi-workshop complex during the late antique period at Sagalassos is contextualised within the wider history of local and regional economic development.
Perpetual decline or persistent dominance? Uncovering Anglo-America’s true structural power in global finance
Authors: Fichtner Jan 
Published: June 2016

AbstractThe prediction of America’s decline is a regularly recurring phenomenon; this also pertains to the pivotal field of global finance. This article argues that, first we have to consider the United States together with the other Anglophone countries. The English-speaking countries and territories – Anglo-America – have deep common political and socioeconomic roots, of which the unique global Five Eyes intelligence cooperation is merely one manifestation. In finance, New York and London (NY-LON) constitute the decision-making core of this transnational formation. Second, to analyse the highly complex phenomenon of structural power in the globalised international political economy we have to dig deeper to uncover truly meaningful data. Thus, this article evaluates data for nine central segments of global finance from around the year 2000 to 2014. Contrary to the assertions of many declinists, these data show that Anglo-America’s dominant structural power has been persistent during this period. Moreover, four novel visualisations show that the US-UK axis is the fulcrum of the international financial system. However, contemporary global finance is characterised by a high degree of latent fragility; significant imbalances, inequalities and contradictions persist and are even likely to grow, potentially undermining the legitimacy and the stability of the whole system.
The use of psychiatric services by young adults who came to Sweden as teenage refugees: a national cohort study
Authors: Manhica H. , Almquist Y. , Rostila M. , Hjern A. 
Published: June 2016

Aims.To investigate the patterns of use of different forms of psychiatric care in refugees who settled in Sweden as teenagers.Method.Cox proportional hazards models were used to estimate the use of different forms of psychiatric care from 2009 to 2012 in a population of 35 457 refugees, aged from 20 to 36, who had settled in Sweden as teenagers between 1989 and 2004. These findings were compared with 1.26 million peers from the same birth cohorts in the general Swedish population.Results.Unaccompanied and accompanied refugees were more likely to experience compulsory admission to a psychiatric hospital compared with the native Swedish population, with hazard ratios (HRs) of 2.76 (1.86–4.10) and 1.89 (1.53–2.34), respectively, as well as psychiatric inpatient care, with HRs of 1.62 (1.34–1.94) and 1.37 (1.25–1.50). Outpatient care visits by the young refugees were similar to the native Swedish population. The longer the refugees had residency in Sweden, the more they used outpatient psychiatric care. Refugees born in the Horn of Africa and Iran were most likely to undergo compulsory admission, with HRs of 3.98 (2.12–7.46) and 3.07 (1.52–6.19), respectively. They were also the groups who were most likely to receive inpatient care, with HRs of 1.55 (1.17–2.06) and 1.84 (1.37–2.47), respectively. Our results also indicated that the use of psychiatric care services increased with the level of education in the refugee population, while the opposite was true for the native Swedish population. In fact, the risks of compulsory admissions were particularly higher among refugees who had received a secondary education, compared with native Swedish residents, with HRs of 4.72 (3.06–7.29) for unaccompanied refugees and 2.04 (1.51–2.73) for accompanied refugees.Conclusions.Young refugees received more psychiatric inpatient care than the native Swedish population, with the highest rates seen in refugees who were not accompanied by their parents. The discrepancy between the use of inpatient and outpatient care by young refugees suggests that there are barriers to outpatient care, but we did note that living in Sweden longer increased the use of outpatient services. Further research is needed to clarify the role that education levels among Sweden's refugee populations have on their mental health and health-seeking behaviour.
The Water World of the Orang Suku Laut in Southeast Asia
Authors: Chou Cynthia 
Published: June 2016

AbstractThis article explores how the Orang Suku Laut, an indigenous Malay roving fishing community, perceives the water world in Southeast Asia. Their rites of childbirth, naming and the enculturation of their young present invaluable ethnographic data that challenge us to develop new ways to conceptualise ‘water spaces’ as well as to widen our academic inquiry into the less understood ways of spatial imaginings.

Abstract

Background:
This exploratory analysis evaluated second-line (2L) therapy for metastatic pancreatic cancer in a large phase 3 trial (MPACT).

Methods:
Patients who received first-line (1L) nab-paclitaxel+gemcitabine (nab-P+Gem) or Gem were assessed for survival based on 2L treatment received. Multivariate analyses tested influence of treatment effect and prognostic factors on survival.

Results:
The majority of 2L treatments (267 out of 347, 77%) contained a fluoropyrimidine (5-fluorouracil or capecitabine). Median total survival (1L randomisation to death) for patients who received 2L treatment after 1L nab-P+Gem vs Gem alone was 12.8 vs 9.9 months (P=0.015). Median total survival for patients with a fluoropyrimidine-containing 2L therapy after nab-P+Gem vs Gem was 13.5 vs 9.5 months (P=0.012). Median 2L survival (duration from start of 2L therapy to death) was 5.3 vs 4.5 months for nab-P+Gem vs Gem, respectively (P=0.886). Factors significantly associated with longer post-1L survival by multivariate analyses included 1L nab-P+Gem, receiving 2L treatment, longer 1L progression-free survival, and Karnofsky performance status⩾70 and neutrophil-to-lymphocyte ratio⩽5 at the end of 1L treatment.

Conclusions:
These findings support the use of 2L therapy for patients with metastatic pancreatic cancer. Fluoropyrimidine-containing treatment after 1L nab-P+Gem is an active regimen with significant clinical effect.
Droplet barcoding for massively parallel single-molecule deep sequencing
Authors: Lan Freeman , Haliburton John R. , Yuan Aaron , Abate Adam R. 
Published: June 2016

AbstractThe ability to accurately sequence long DNA molecules is important across biology, but existing sequencers are limited in read length and accuracy. Here, we demonstrate a method to leverage short-read sequencing to obtain long and accurate reads. Using droplet microfluidics, we isolate, amplify, fragment and barcode single DNA molecules in aqueous picolitre droplets, allowing the full-length molecules to be sequenced with multi-fold coverage using short-read sequencing. We show that this approach can provide accurate sequences of up to 10 kb, allowing us to identify rare mutations below the detection limit of conventional sequencing and directly link them into haplotypes. This barcoding methodology can be a powerful tool in sequencing heterogeneous populations such as viruses.
Surface engineering of hierarchical platinum-cobalt nanowires for efficient electrocatalysis

Published: June 2016

AbstractDespite intense research in past decades, the lack of high-performance catalysts for fuel cell reactions remains a challenge in realizing fuel cell technologies for transportation applications. Here we report a facile strategy for synthesizing hierarchical platinum-cobalt nanowires with high-index, platinum-rich facets and ordered intermetallic structure. These structural features enable unprecedented performance for the oxygen reduction and alcohol oxidation reactions. The specific/mass activities of the platinum-cobalt nanowires for oxygen reduction reaction are 39.6/33.7 times higher than commercial Pt/C catalyst, respectively. Density functional theory simulations reveal that the active threefold hollow sites on the platinum-rich high-index facets provide an additional factor in enhancing oxygen reduction reaction activities. The nanowires are stable in the electrochemical conditions and also thermally stable. This work may represent a key step towards scalable production of high-performance platinum-based nanowires for applications in catalysis and energy conversion.
