Compression performance and bearing capacity calculation model of small-eccentricity columns strengthened with textile-reinforced mortar (TRM)
Authors: Yin S. P. , Hu X. Q. , Hua Y. T.
Published: June 2019

To study the compression performance of TRM-strengthened columns with small eccentricities, a total of 9 reinforced concrete (RC) columns with end corbels were subjected to compression testing. The test parameters are as follows: the number of textile layers, the ratio of longitudinal reinforcement, and polyvinyl alcohol (PVA) short-cut fiber volume fraction. The experimental results indicated that, compared to the control, columns with three layers of textile exhibited an approximately 10.66% increase in the bearing capacity. However, the effect increased only slightly when the number of textile layers increased to 4. Besides, the effect was improved with the increase in the ratio of longitudinal reinforcement and PVA fiber volume fraction. Finally, based on laboratory tests and related research results, a model for calculating normal section bearing capacity of TRM-strengthened columns with small eccentricities was presented. A comparison of the theoretical and experimental data demonstrated the applicability of the proposed model.
A Fault-Tolerant Scheduling Algorithm Based on Checkpointing and Redundancy for Distributed Real-Time Systems
Authors: Kada Barkahoum , Kalla Hamoudi
Published: June 2019

Real-time systems are becoming ever more widely used in life-critical applications, and the need for fault-tolerant scheduling can only grow in the years ahead. This article presents a novel fault tolerance approach for tolerating transient faults in hard real-time systems. The proposed approach combines both checkpointing with rollback and active replication to tolerate several transient faults. Based on this approach, a new static fault-tolerant scheduling algorithm SFTS is presented. It is based on a list of scheduling heuristics which satisfy the application time constraints even in the presence of faults by exploring the spare capacity of available processors in the architecture. Simulation results show the performance and effectiveness of the proposed approach compared to other fault-tolerant approaches. The results reveal that in the presence of multiple transient faults, the average timing overhead of this approach is lower than checkpointing technique. Moreover, the proposed algorithm SFTS achieves better feasibility rate in the presence of multiple transient faults.
RIDISTRIBUZIONE, CRESCITA, CAMBIAMENTO STRUTTURALE E DOLLARIZZAZIONE: CAPIRE LE PROSPETTIVE ECUADORIANE
Authors: Missaglia Marco
Published: June 2019

La sezione 1 è dedicata all'analisi delle tendenze fondamentali dell'economia ecuadoriana negli ultimi tre decenni. Nonostante non ci siano segni di cambiamento strutturale, le condizioni delle persone sono migliorate significativamente, soprattutto negli ultimi dieci anni. Ciò è stato possibile, come è spiegato nella sezione 2, per il crescente ruolo dello Stato come principale motore della crescita e della redistribuzione. Questo "miracolo", tuttavia, non può sostenersi nel tempo e la profonda crisi degli ultimi due anni lo dimostra. La sezione 3 intende dimostrare che i sintomi della "malattia olandese" sono chiaramente presenti nell'economia ecuadoriana e bloccano il suo sviluppo nel contesto di un modello produttivo invariato. Rimuovere quegli ostacoli è difficile e la dollarizzazione sta diventando un ostacolo-chiave. La sezione 4 si conclude quindi con un"analisi della dollarizzazione, il regime monetario introdotto all'inizio del 2000, che certamente ha contribuito a salvare l'economia e il suo sistema finanziario dalla grande crisi del 1998-1999. Se la dollarizzazione era un buon rimedio per quel tipo di malattia, cioè il disastro finanziario, le cose sono ora diverse ed essa si sta trasformando in un fattore negativo: infatti sta impedendo alle autorità ecuadoriane non solo di attuare politiche monetarie, ma anche politiche di cambiamento fiscale e strutturale. La protezione dei risparmi già accumulati non può infatti essere perseguita rallentando o addirittura bloccando la formazione di nuovo risparmio.
Potenciant un turisme cultural atractiu pel patrimoni de Llíria més enllà dels pilars tradicionals d'arqueologia, bandes de música i fires gastronòmiques: Turisme 2.0

Analysis of Global Three-Dimensional Aerosol Structure with Spectral Radiance Matching
Authors: Liu Dong , Chen Sijie , Cheng Chonghui , Barker Howard W. , Dong Changzhe , Ke Ju , Wang Shuaibo , Zheng Zhuofan
Published: June 2019

Abstract. A method is assessed which expands aerosol vertical profiles inferred from nadir-pointing lidars to cross-track locations next to nadir columns. This is achieved via matching of passive radiances at off-nadir locations with their counterparts that are collocated with lidar data. This spectral radiance matching (SRM) method is tested using profiles inferred from CALIPSO lidar observations and collocated MODIS passive imagery for the periods 10–25 April and 14–29 September 2015. CALIPSO profiles are expanded out to 100 km on both sides of the daytime ground-track. Reliability of constructed profiles that are removed from the ground-track by N km are tested by requiring the algorithm to reconstruct profiles using only profiles that are removed from it along-track by more than N km. When sufficient numbers of pixels/columns are available, the SRM method can correctly match ~ 75 % and ~ 68 % of aerosol vertical structure at distances of 30 km and 100 km from the ground-track, respectively. The construction algorithm is applied to the east coast of Asia during spring 2015. Vertical distributions of different aerosol subtypes indicate that the region was dominated by dust and polluted dust transported from the continent. It is shown that aerosol optical depths inferred from ground-based measurements agree with those constructed by the SRM method better than direct observation from CALIPSO, and close to those inferred from MODIS radiances.
CALIPSO Level 3 Stratospheric Aerosol Product: Version 1.00 Algorithm Description and Initial Assessment

Published: June 2019

Abstract. In August 2018, the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) project released a new level 3 stratospheric aerosol profile data product derived from nearly 12 years of measurements acquired by the space-borne Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP). This monthly averaged, gridded level 3 product is based on version 4.2 of the CALIOP level 1 and level 2 data products, which feature significantly improved calibration that now makes it possible to reliably retrieve profiles of stratospheric aerosol extinction and backscatter coefficients. This paper describes the science algorithm and data handling techniques that were developed to generate the CALIPSO version 1.00 level 3 stratospheric aerosol profile product. Further, we show that the retrieved extinction profiles capture the major stratospheric perturbations over the last decade resulting from volcanic eruptions, extreme smoke events, and signatures of stratospheric dynamics. Initial assessment of the product by inter-comparison with the stratospheric aerosol retrievals from the Stratospheric Aerosol and Gas Experiment III (SAGE III) on the International Space Station (ISS) indicates good agreement in the tropical stratospheric aerosol layer (30° N–30° S), where the average difference between zonal mean extinction profiles is typically less than 25 % between 20 km and 30 km. However, differences can exceed 100 % in the very low aerosol loading regimes found above 25 km at higher latitudes.
Historic photographs of glaciers and glacial landforms from the R. S. Tarr collection at Cornell University
Authors: Elliott Julie , Pritchard Matthew E.
Published: June 2019

Abstract. Historic photographs are useful for documenting glacier, environmental, and landscape change and we have digitized a collection of about 1949 images collected during an 1896 expedition to Greenland and trips to Alaska in 1905, 1906, 1909, and 1911, led by Ralph Stockman Tarr and his students at Cornell University. These images are openly available in the public domain through Cornell University Library (http://digital.library.cornell.edu/collections/tarr). The primary research targets of these expeditions were glaciers (there are about 990 photographs of at least 58 named glaciers) but there are also photographs of people, villages, geologic features, and formerly glaciated regions, including glacial features near Cornell University in Ithaca, New York. Some of the glaciers featured in the photographs have retreated significantly in the last century or even completely vanished. For many glaciers, multiple views are available, potentially allowing the use of photogrammetric techniques to generate three-dimensional models of the ice extent. While some of these photographs have been used in publications in the early 20th century, most of the images are only now widely available for the first time. The digitized collection also includes about 300 lantern slides made from the expedition photographs and other related images and used in classes and public presentations about glaciers and glaciations by several Cornell faculty over the decades. The images are of scientific interest for understanding glacier and ecological change, of public policy interest for documenting climate change, of historic and anthropological interest as local people, settlements, and gold-rush era paraphernalia are featured in the images, and of artistic and technological interest as the photographic techniques used were cutting-edge for their time.
Von der Inkorporierung und Verkörperung des Sozialen zur Somatisierung der Umwelt: Posthumanistische Überlegungen zum biosozialen Subjekt
Authors: Strüver Anke
Published: June 2019

Abstract. With the recognition of relational thinking, methodologies approaching spaces as containers were discarded and reconfigured in social geography. However, there are other “containers” still present in these debates – and present as part of the relations in space – such as the “black box” of the human body. In order to advance the opening of the Black Box of the Body (Guthman, 2012), the article discusses social geographical thinking concerning materiality after the Cultural Turn, which concentrates on a post-dualist and thus a post-humanist concept of materiality. The ensuing extension of the epistemological critique of dualistic thinking as part of the cultural turn by an ontological critique refers to radical-relational conceptions of NatureCultures (Haraway) and Posthumanist Performativities (Barad), which comprise discursive as well as material power relations. These conceptions neither romanticize nature (or even interpret it in a reactionary way) nor inflate culture. Rather, such a perspective allows to examine the materiality and intra-activity of social environmental conditions at the micro-level of the embodied subject, considering that matter itself acts performatively and even how such performances are enacted. This article concentrates on theoretical crises within social geography in order to discuss the geography of social crises using the example of environmental injustice and the somatization of the environment with respect to food and health. By extending the “surface”-view on embodied subjects as being socio-culturally encoded and discursively normalized, chemical-biological metabolic processes are also addressed. Therefore, the body is understood as the place where social crises, structures of inequality and discursive categories materialize.
Modular Assessment of Rainfall–Runoff Models Toolbox (MARRMoT) v1.2: an open-source, extendable framework providing implementations of 46 conceptual hydrologic models as continuous state-space formulations
Authors: Knoben Wouter J. M. , Freer Jim E. , Fowler Keirnan J. A. , Peel Murray C. , Woods Ross A.
Published: June 2019

Abstract. This paper presents the Modular Assessment of
Rainfall–Runoff Models Toolbox (MARRMoT): a modular open-source toolbox
containing documentation and model code based on 46 existing conceptual
hydrologic models. The toolbox is developed in MATLAB and works with Octave.
MARRMoT models are based solely on traceable published material and model
documentation, not on already-existing computer code. Models are implemented
following several good practices of model development: the definition of model
equations (the mathematical model) is kept separate from the numerical
methods used to solve these equations (the numerical model) to generate
clean code that is easy to adjust and debug; the implicit Euler
time-stepping scheme is provided as the default option to numerically
approximate each model's ordinary differential equations in a more robust
way than (common) explicit schemes would; threshold equations are smoothed
to avoid discontinuities in the model's objective function space; and the
model equations are solved simultaneously, avoiding the physically unrealistic
sequential solving of fluxes. Generalized parameter ranges are provided to
assist with model inter-comparison studies. In addition to this paper and
its Supplement, a user manual is provided together with several
workflow scripts that show basic example applications of the toolbox. The
toolbox and user manual are available from https://github.com/wknoben/MARRMoT (last access: 30 May 2019; https://doi.org/10.5281/zenodo.3235664). Our main
scientific objective in developing this toolbox is to facilitate the
inter-comparison of conceptual hydrological model structures which are in
widespread use in order to ultimately reduce the uncertainty in model
structure selection.
A 50-year analysis of hydrological trends and processes in a Mediterranean catchment
Authors: Folton Nathalie , Martin Eric , Arnaud Patrick , L'Hermite Pierre , Tolsa Mathieu
Published: June 2019

Abstract. The Réal Collobrier hydrological observatory in south-eastern France,
managed by Irstea since 1966, constitutes a benchmark site for regional
hydro-climatology. Because of the dense network of stream gauges and
rain gauges available, this site provides a unique opportunity to evaluate
long-term hydro-meteorological Mediterranean trends. The main catchment (70 km2) and its sub-catchments are located in the Massif des Maures of south-eastern France, close to the Mediterranean coast. The vegetation is
composed of forest mainly calcified on crystalline soils (maquis of heath,
cork-oak, maritime pine and chestnut). Direct human influence has been
negligible over the past 50 years. The land use and land cover has remained
almost unchanged, with the notable exception of a wildfire in 1990 that
impacted a small sub-catchment. Therefore changes in the hydrological
response of the catchments are caused by changes in climate and/or physical
conditions. This study investigates changes in observational data using up
to 50-year daily series of precipitation and streamflow. The analysis used
several climate indices describing distinct modes of variability, at
inter-annual and seasonal timescales. Trends were assessed by the
Mann–Kendall method. The analysis also used hydrological indices describing
drought events based on daily data for a description of low flows, in
particular in terms of timing and severity. The analysis shows that there is
a marked tendency towards a decrease in the water resources of the Réal
Collobrier catchment in response to climate trends, with a consistent
increase in drought severity and duration. But the changes are variable
among the sub-catchments.
The Idea of Liberty in the Fichtean Natural Right
Authors: Arrese Igor Hector Oscar Oscar
Published: June 2019

En este trabajo se discute la interpretación de Isaiah Berlin de la filosofía política fichteana en términos de un organicismo. Esta interpretación muestra que las libertades individuales juegan un rol fundamental en la educación de los ciudadanos futuros en tanto que ésta es una tarea realizada por los padres y no por el Estado. Sin embargo, Fichte no defiende una idea de la libertad individual como no-interferencia, aun cuando las similitudes entre su teoría y la de Humboldt sugieran lo contrario. Del mismo modo, Fichte no defendió tampoco la idea de la libertad como no-dominación, como revela la comparación con la teoría de Philip Pettit. Por el contrario, Fichte sostuvo que la educación de los futuros ciudadanos tiene sentido únicamente cuando las libertades individuales son consideradas como inextricablemente unidas con la propiedad.

 

This paper discusses Isaiah Berlin’s interpretation of Fichtean political philosophy in terms of organicism. It shows that individual liberties play a fundamental role in the education of future citizens as a task performed by parents, not the state. However, Fichte did not defend an idea of individual liberty or non-interference, even if similarities between his theory and Humboldt’s suggest the contrary. At the same time, Fichte also did not espouse the idea of freedom as non-domination, as a comparison with Philip Pettit’s theory reveals. By contrast, Fichte posited that the education of future citizens makes sense only if individual liberties are considered inextricably linked to property.
El escéptico Pirrón de Élide: el último presocrático y su conexión con la escuela de abdera.

Siempre se ha reconocido en Pirrón de Élide el inicio puntual del escepticismo griego.Sabemos ya hoy que esta información, sesgada, proviene más de la necesidad de Enesidemo derefundar el movimiento, que de la realidad filosófica. En este artículo demostramos que Pirrón, nituvo consciencia de ser un escéptico, ni, en rigor, inició ninguna nueva corriente. Su deslizamiento,y posterior reconocimiento, hacia el escepticismo, debe más bien encuadrarse en el natural desarrollode la filosofía abderita, a través de Metrodoro de Quíos, discípulo de Demócrito, Anaxarco maestro dePirrón y Nausífanes su discípulo. Y todo debido al afán aventurero del personaje de Élide al enrolarseen el séquito de Alejandro Magno.

Authors: John Akomolafe Kehinde
Published: June 2019

This paper examines the causality between electricity consumption and economic growth in Nigeria, with a focus on sectorial analysis. The sectors considered are manufacturing sector, agriculture sector, and the service sector. The study covers the periods from 1981 to 2014. The study was done in a vector error correction model (VECM). The results show that the causality run from  manufacturing sector to electricity consumption in long run, but a bidirectional causality in the short run, from electricity consumption to service sector output  in the long run, and  from electricity consumption to service sector output in long run. There is no short run causality between electricity consumption and service sector and agricultural sectors outputs. The paper concludes with the recommendation that government should be careful in implementing electricity conservation policy

Nederlandse Wet op de reisovereenkomst: (on)werkbaarheid in de praktijk

De nieuwe wet op de reisovereenkomst (titel 7A van Boek 7 BW) welke wet op 1 juli 2018 in werking is getreden, is eigenlijk een vrijwel letterlijke vertaling van de Richtlijn Pakketreizen en Gekoppelde Reisarrangementen van 25 november 2015. Hoewel de doelstelling van de Richtlijn, te weten meer bescherming voor de reiziger en maximum harmonisatie tussen de lidstaten een mooi streven was, blinkt de Richtlijn niet uit in duidelijkheid en zijn er voorafgaand aan de totstandkoming ervan vele ontwerpen de revue gepasseerd die de eindstreep van het wetgevingsproces niet hebben gehaald. Desondanks heeft de Nederlandse wetgever deze moeilijke wetgeving uit Brussel redelijk leesbaar geïmplementeerd in de Nederlandse wet. Onzes inziens is de Richtlijn, en daarmee dus ook de Nederlandse wet, op een aantal vlakken niet duidelijk en lastig uit te leggen aan zowel de ondernemers in de reisbranche als aan de reiziger. Ook zijn er enkele onvolkomenheden in de wet geslopen, mede veroorzaakt door een slordige vertaling van de Richtlijn in het Nederlands, waar de Nederlandse wetgever overigens geen invloed op had. In dit artikel willen we met name stilstaan bij een aantal van deze onduidelijkheden en moeilijkheden. Zo zijn de definitiebepalingen bijvoorbeeld vrij ingewikkeld en roept de afbakening tussen een pakketreis en het nieuwe fenomeen van het gekoppeld reisarrangement vragen op. Ook zetten wij vraagtekens bij de vergaande informatieverplichtingen, de positie van de zakenreiziger en de wijze waarop de garantieverplichtingen in Nederland zijn geïmplementeerd. Hoe werkzaam de wet zal zijn in de praktijk van alle dag, zal de komende jaren dus nog moeten blijken.

Published: June 2019

À medida que as micro e pequenas empresas (MPEs) buscam inovar para superar a crise econômica, os programas de fomento surgem como uma alternativa para este fim. Estes programas objetivam fortalecer as empresas através do aumento da competitividade, abordando inovações na gestão, no processo, no produto, no marketing. Motivados pelas discussões relativas ao perfil inovador das MPEs, esta pesquisa buscou identificar a existência de correlação entre o grau de desenvolvimento organizacional (GO) e o grau de inovação (GI). Analisamos os resultados dos diagnósticos de inovação e organizacional de 120 EPPs, mediante preenchimento de formulários em um processo de entrevista estruturada, baseadas no Radar da Inovação. A amostra é igualmente distribuída em três grupos de 40 empresas dos setores da indústria de alimentos, móveis e confecções do estado de Pernambuco. Os resultados mostraram uma tendência representada por algum grau de dependência entre GO e GI da amostra analisada. Fica evidente a existência de uma correlação não linear entre essas variáveis em decorrência dos diferentes graus de maturidade de cada empresa, mesmo entre àquelas que pertencem ao mesmo setor de atuação. Com relação ao perfil inovador, concluímos que 69,2% das empresas pesquisadas são categorizadas como inovadoras ocasionais.

Published: June 2019

Objetiva-se modelar por simulação computacional um sistema que represente o processo de atendimento em uma imobiliária, obtendo seu Lead Time, avaliando e mensurando a capacidade de atendimento da empresa. Justificase o tema pelo fato da imobiliária estar perdendo um de seus diferenciais, que é a agilidade e excelência do atendimento ao cliente. O método de pesquisa utilizado foi a modelagem e simulação, auxiliado pela ferramenta IDEF-Sim para mapeamento de processos e pelo software ProModel® para modelagem computacional. A partir dos dados coletados criaram-se quatro cenários e fez-se comparações com o atual, a fim de identificar qual seria a melhor forma de se atingir aos objetivos propostos. Após análises chegouse à conclusão de que o segundo cenário modelado, seria o melhor para a empresa, pois um funcionário que estava com tempo ocioso, foi remanejado de setor, reduzindo o Lead Time de atendimento em mais de três minutos (16% do tempo total).

Anhänger entgegengesetzter Positionen zu einem konflikthaltigen Thema tendieren dazu, die Medienberichterstattung zu diesem Thema als jeweils zuungunsten ihrer eigenen Position verzerrt wahrzunehmen. Dies wird als Hostile-Media-Effekt oder Hostile-Media-Wahrnehmung bezeichnet. In einer Befragungsstudie im Kontext der sogenannten Flüchtlingskrise wurde geprüft, wie Befürworter und Gegner einer flüchtlingsfreundlichen Willkommenskultur die inhaltliche Tendenz der Berichterstattung über das Thema wahrgenommen haben. Die Ergebnisse der Untersuchung zeigen, dass Hostile-Media-Wahrnehmungen bei beiden Gruppen auftreten, in besonderem Maße bei den Gegnern der Willkommenskultur. Die Wahrnehmungen korrelieren mit einem geringeren Vertrauen in die Medien, einer schlechteren Bewertung der Qualität der themenspezifischen Berichterstattung und erhöhter Wut.
GEOLOGICAL AND GEOPHYSICAL CHARACTERISTICS OF THE ANABAR‐KHATANGA OIL AND GAS PROVINCE; NUMERICAL MODELING OF THE PROCESSES OF FORMATION OF SALT DOMES (SIBERIAN SECTOR OF THE RUSSIAN ARCTICS)
Authors: Kontorovich V. A. , Lunev В. V. , Lapkovsky V. V.
Published: June 2019

The article discusses the geological structure, oil‐and‐gas‐bearing capacities and salt tectogenesis of the Anabar‐Khatanga saddle located on the Laptev Sea shore. In the study area, the platform sediments are represented by the 14‐45 km thick Neoproterozoic‐Mesozoic sedimentary complexes. The regional cross‐sections show the early and middle Devonian salt‐bearing strata and associated salt domes in the sedimentary cover, which may be indicative of potential hydrocarbon‐containing structures. Diapirs reaching the ground surface can be associated with structures capable of trapping hydrocarbons, and typical anticline structures can occur above the domes buried beneath the sediments. In our study, we used the algorithms and software packages developed by A.A. Trofimuk Institute of Petroleum Geology and Geophysics (IPGG SB RAS). Taking into account the structural geological features of the study area, we conducted numerical simulation of the formation of salt dome structures. According to the numerical models, contrasting domes that reached the ground surface began to form in the early Permian and developed most intensely in the Mesozoic, and the buried diapirs developed mainly in the late Cretaceous and Cenozoic.
If your group is (not) great: Positive vs. negative trait priming motivates majorities and minorities to adapt essentialist attributions
Authors: Zeromskyte Ruta , Wagner Wolfgang
Published: June 2019

In the present study we investigate the mutability of essentialist ingroup and outgroup attributions in relation to positive and negative ingroup trait priming for ethnic minority and majority members in two countries (Study 1 in Austria: with Austrians and Austrian Turks; Study 2 in Lithuania: with Lithuanians and Lithuanian Poles). Both studies demonstrate that essentialist ingroup-attributions were lower when both minority and majority members were encountering negative (as compared to neutral/positive) ingroup traits. Only minority members raised the level of essentialist ingroup-attributions with positive ingroup trait priming. Additionally, Study 2 compared essentialist attributions in two regions (typical and numerically reversed minority-majority groups). The typical majority Lithuanians and “reversed” Poles attributed a lower level of ingroup-essence than the typical minority Poles and “reversed” Lithuanians. With ingroup trait priming, the “reversed” groups showed the same pattern, changing the levels of self-attributed essence like the ethnic Lithuanians/Poles in typical regions. The results demonstrate the mutable use of group-based essentialist self-attributions as a response to manipulation of positive/negative trait presentation of the ingroup. Consequently, group-essentialization is not a static property of a group but situationally and strategically variable. Exploration of reversed minority-majority situations reveals additional aspects of this variability.

Os dados analisados foram coletados de uma série temporal de 10 anos, e a escolha do período teve como critério englobar uma época na qual vigorou uma estabilidade econômica, tendo o cuidado de minimizar as mudanças de metodologias dos institutos de pesquisa considerados. Fazendo uso da literatura que enfatiza a qualidade da análise de crédito mediante as assimetrias de informação, seleção adversa e risco moral, buscou-se avaliar os efeitos da elevação do volume de crédito sobre a inadimplência, inflação e atividade econômica. Não houve a intenção de trabalhar à luz de uma única corrente de pensamento, e sim, fazer uso de fontes distintas que possibilitassem observações das mudanças do volume de crédito e seus efeitos na sociedade.
Revitalizing Indigenous Women’s Water Governance Roles in Impact and Benefit Agreement Processes Through Indigenous Legal Orders and Water Stories
Authors: Hania Patricia
Published: June 2019

In the Canadian mining sector, the use of an impact and benefit agreement (IBA) is the dominant legal instrument that structures the legal relationship between a First Nation and a proponent. However, barriers to Indigenous women’s participation in IBA law-making exist, which raises the question : How can IBA law-making be strengthen to include Indigenous women ? Emergent scholarship by Graben, Cameron and Morales takes up this question of Indigenous women’s participation in their gendered approach. In this article, I critically examine and expand upon Graben, Cameron and Morales gendered approach, and argue that mining, Indigenous women, and water are interconnected, and advancing Indigenous women’s participation is essential, as argued by Graben, Cameron and Morales. However, offering Indigenous women a place at the IBA negotiating table is meaningless without recognizing their Indigenous law stories and governance responsibilities to speak for water, as long argued by Indigenous water governance scholars and Indigenous women.

Published: June 2019

Geographical Information Science (GIScience), also Geographical Information Science and Systems, is a multi-faceted research discipline and comprises a wide variety of topics. Investigation into data management and interoperability of geographical data and environmental data sets for scientific analysis, visualisation and modelling is an important driver of the Information Science aspect of GIScience, that underpins comprehensive Geographical Information Systems (GIS) and Spatial Data Infrastructure (SDI) research and development. In this article we present the 'Grounded Design' method, a fusion of Design Science Research (DSR) and Grounded Theory (GT), and how they can act as guiding principles to link GIScience, Computer Science and Earth Sciences into a converging GI systems development framework. We explain how this bottom-up research framework can yield holistic and integrated perspectives when designing GIS and SDI systems and software. This would allow GIScience academics, GIS and SDI practitioners alike to reliably draw from interdisciplinary knowledge to consistently design and innovate GI systems.

Context

Opioids may be prescribed for the short-term management of acute-onset back pain in the setting of trauma or for long-term management of chronic back pain. More than 50% of regular opioid users report taking them for back pain.

Objective

To investigate whether surgical intervention reduces opioid requirements by patients taking opioids for back pain and whether there is a difference between county and managed care hospitals in this postoperative reduction of opioid requirement.

Methods

A retrospective medical record review of 118 patients who underwent elective lumbar fusion at 4 hospitals (2 county hospitals and 2 managed care hospitals) was conducted. Opioid requirements before and after surgical intervention and at the 30-day outpatient follow-up were evaluated.

Results

Forty medical records were included in the study. An overall decrease in opioid use was found in the postoperative follow-up phase after lumbar fusion in both the county and managed care hospitals. This reduction was statistically significant at 3 of 4 hospitals (P<0.01). When the data were pooled by facility type, the significance remained for county facilities (P<.01) but not managed care facilities (P=.18). Moreover, there was a significant decrease in opioid use during the postoperative inpatient phase for county compared with managed care facilities (P=.0427). The pain rating reported by patients during the hospital stay was significantly higher at county compared with managed care hospitals (P=.0088); however, the difference at discharge was not significant (P=.14).

Conclusion

Our study indicates that lumbar fusion is associated with a significant decrease in opioid use (P<.05) compared with nonsurgical management. Overall, the difference in decreased opioid use between county and managed care hospitals after lumbar fusion was not significant.
Freshwater reservoir offsets on radiocarbon-dated dog bone from the headwaters of the St. Lawrence River, USA

Isotopic analysis of dog (Canis lupus familiaris) bone recovered from archaeological sites as proxies for human bone is becoming common in North America. Chronological placement of the dogs is often determined through radiocarbon dating of dog bone. The Great Lakes, their tributaries, and nearby lakes and streams were important fisheries for Native Americans prior to and after sustained European presence in the region. Carbon entering the food web in freshwater systems is often not in full isotopic equilibrium with the atmosphere, giving rise to spuriously old radiocarbon ages in fish, other aquatic organisms, and their consumers. These freshwater reservoir offsets (FROs) have been noted on human and dog bone in several areas of the world. Here we report the results of multi-tracer Bayesian dietary modeling using δ15N and δ13C values on dog bone collagen from mid-fifteenth to mid-sixteenth-century Iroquoian village sites at the headwaters of the St. Lawrence River, New York, USA. Results indicate that fish was an important component of dog diets. A comparison of radiocarbon dates on dog bone with dates on deer bone or maize from the same sites indicate FROs ranging from 97 ± 24 to 220 ± 39 14Cyr with a weighted mean of 132 ± 8 14Cyr. These results suggest that dog bone should not be used for radiocarbon dating in the absence of modeling to determine fish consumption and that previously reported radiocarbon dates on human bone from the larger region are likely to have FROs given the known importance of fish in regional human diets.
Aspartyl Aminopeptidase Suppresses Proliferation, Invasion, and Stemness of Breast Cancer Cells via Targeting CD44

Published: June 2019

Although involved in diverse cancer processes, the function of aspartyl aminopeptidase (DNPEP) in breast cancer remains elusive. Here, we reported that DNPEP is significantly downregulated in breast cancer tissues. Overexpression of DNPEP resulted in decreased breast cancer cells proliferation, migration, and invasion, while DNPEP knockdown had the opposite effect. Interestingly, we showed that the reduced DNPEP levels were correlated with the elevated cluster of differentiation 44 (CD44) levels in breast cancer. DNPEP promoted CD44 ubiquitin‐proteasome‐independent degradation, which is dependent on the hydrolase activity of DNPEP. Ectopic DNPEP expression significantly suppressed the stemness properties of breast cancer cells. These results shed light on the prospect of DNPEP in manipulating breast cancer progression.

Published: June 2019

Three dinuclear dysprosium(III) complexes, [Dy2L2(O2CPh)2]⋅2 MeOH (1), [Dy2L2{(2‐NO2)O2CPh}2] (2), and [Dy2L2{(2‐OH)O2CPh}2]⋅MeOH⋅MeCN (3) (H2L=N1,N3‐bis(4‐chlorosalicyladehyde)diethylenetriamine), have been synthesized and structurally characterized. Complexes 1–3 possess similar Ln2 cores and differ in substituents at the benzyl rings of benzoates. Direct current (dc) magnetic susceptibility studies in the 2–300 K range showed weak antiferromagnetic interactions between two dysprosium(III) ions in 1–3. The alternating current (ac) magnetic susceptibility measurements indicated that they all exhibited SMM behavior. The strategic attachment of the −NO2 group (in 2) and the −OH functionality (in 3) on the skeleton of the benzoic acid led to subtle variations of the bond lengths and bond angles in the coordination environments of the central dysprosium(III) ions, consequently resulting in the enhancement of the energy barriers for 2 and 3. Complete‐active‐space self‐consistent field (CASSCF) calculations were employed to rationalize the experimental outcomes. Theoretical calculations confirm the existence of antiferromagnetic interactions in 1–3, and the calculated dc magnetic susceptibility data agree well with those obtained experimentally. The computational results reveal more axial g tensors, as well as higher first excited Kramers doublets in 2 and 3; thus resulting in higher energy barriers in compounds 2 and 3.
Thermodynamics and phase transitions in galaxy clustering
Authors: Demir N. , Iqbal N.
Published: June 2019

The phenomenon of galaxy clustering was studied from the perspective of the gravitational phase transition, which is somewhat different from a phase transition in materials science. There is evidence that the phase transition describing galaxy clustering in an expanding universe is a first‐order phase transition exhibiting a mixed phase. As such, the Clausius–Clapeyron equation is relevant for studying such a system. In this work, we derive a general analog of the Clausius–Clapeyron equation that applies not only toward the coexistence curve in pressure–temperature space, but to a more general parameter space. One key finding is that a cusp exists at the critical point in this mixed phase when viewed in this more general parameter space. We extend this formalism to derive an equation for the curvature of the phase coexistence curve in pressure–temperature space and a more general parameter space. We also verify previous findings of hysteresis in the system via an independent free energy analysis.

Foam cells are specialized types of cells which predominate the necrotic core of atherosclerotic plaque. Recently, autophagy‐mediated cholesterol efflux from foam cells has been proposed as a beneficial therapy for atherosclerosis. The purpose of this study was to delineate the underlying molecular mechanism of oligomeric proanthocyanidins (OPC) and epigallocatechin gallate (EGCG) induced autophagy of foam cells and associated cholesterol efflux. The oxidized low‐density lipoprotein induced foam cells demonstrated impaired autophagy flux through the downregulated expressions of LC3BII/LC3BI, autophagy related gene‐5, Class III phosphoinositide 3 kinase (Class III PI3K), Beclin1, ABCA1, and ABCG1 with concomitant increase in the expressions of protein 62, Class I phosphoinositide 3 kinase, Akt, and mammalian target of rapamycin. However, these effects were significantly abolished by treatment with OPC and EGCG through activation of autophagy flux via Class III PI3K/Beclin1 and with upregulated expression of transporter proteins ABCA1 and ABCG1. Furthermore, the cholesterol efflux process in the foam cells was activated by lysosomal acid lipase and cathepsin D facilitated lipolysis of lipid droplets. Taken together, our data demonstrate that OPC and EGCG treatment stimulated the coordinated activation of autophagy and cholesterol efflux through Class III PI3K/Beclin1 pathway in foam cells, suggesting a promising therapeutic strategy against atherosclerosis.
