Revision of the pentacrinid stalked crinoids of the genus Endoxocrinus (Echinodermata, Crinoidea), with a study of environmental control of characters and its consequences for taxonomy
Authors: DAVID JEROME , ROUX MICHEL , MESSING CHARLES G. , AMEZIANE NADIA
Published: March 2019

A revision of the stalked crinoid species attributed to the genus Endoxocrinus A.H. Clark, 1908 (Diplocrininae, Pentacrinitidae, Crinoidea, Echinodermata) is conducted using studies on phenotype variation and its relation with environment. Specimens collected via submersible at five sites in the Bahamas exhibit distinct phenotypes that correlate with different apparent ecological niches and serve as references for interpreting specimens dredged in Atlantic and Pacific Oceans where detailed information on their benthic environment is unknown. Documentation of ecophenotypic convergences or divergences allows us to distinguish between adaptive characters and those revealing genetic affinities, and to discuss allopatric evolution and bathymetric zonation. The results suggest the following taxonomy: the genus Endoxocrinus is subdivided into two subgenera, i.e., Endoxocrinus A.H. Clark, 1908 and Diplocrinus Döderlein, 1912 (Annacrinus A. H. Clark, 1923 becomes a junior synonym of Diplocrinus); the subgenus Endoxocrinus is monospecific with E. (E.) parrae [Gervais (in Guérin, 1835)] from the western tropical Atlantic; the subgenus Diplocrinus includes E. (D.) alternicirrus (Carpenter, 1882) from the western and central Pacific, E. (D.) maclearanus (Thomson, 1872) from the western tropical Atlantic, and E. (D.) wyvillethomsoni (Jeffreys, 1870) from the northeastern Atlantic. Endoxocrinus (E.) parrae includes three subspecies adapted to different habitats and depths: E. (E.) parrae parrae usually in 154–518 m with moderate to high current velocity and moderate turbulence to laminar flow, E. (E.) parrae carolinae (A.H. Clark, 1934) in 504–724 m with moderate current velocity and high turbulence, and E. (E.) parrae prionodes H.L. Clark, 1941 in 402–832 m with high current velocity in laminar flow. E. (D.) alternicirrus includes two subspecies, E. (D.) alternicirrus alternicirrus in 625–1476 m and E. (D.) alternicirrus sibogae (Döderlein, 1907) usually in 364–800 m. E. (D.) maclearanus has a depth range of 432–878 m and occurs as a dwarf variety minimus n. var. in high current velocities and high turbulence. E. (D.) wyvillethomsoni from depths of 1214–2070 m lives on various substrates under a variety of hydrodynamic conditions.

Contributions to the knowledge of Euschistus (Lycipta) with the description of E. (L.) riograndensis sp. nov. (Hemiptera: Heteroptera: Pentatomidae: Pentatominae: Carpocorini)
Authors: WEILER LUCIANA , FERRARI AUGUSTO , GRAZIA JOCELIA
Published: March 2019

Lycipta Stål (1862a) was proposed as a genus to include three species previously placed in Euschistus Dallas – Euschistus illotus Stål, 1860; E. triangulator (Herrich-Schäffer, 1842); and E. scabricornis (Herrich-Schäffer, 1844). Later, Stål (1862b) treated Lycipta as a subgenus of Euschistus and described E. (L.) spurculus. Stål (1872) transferred E. spurculus to Euschistus (Euschistus); treated E. scabricornis as inserti generis (actually Agroecus scabricornis); and added three new species to Euschistus (Lycipta). As a result (Stål 1872), there are five species: E. (L.) cornutus (Dallas, 1851); E. (L.) cribrarius Stål, 1872; E. (L.) illotus; E. (L.) picticornis Stål, 1872; and E. (L.) triangulator. Rolston (1982) added five new species to Lycipta: E. (L.) luridus (Dallas, 1851); E. (L.) circumfusus Berg, 1883; E. (L.) imitator Berg, 1878; E. (L.) machadus Rolston, 1982; and E. (L.) sharpi Bergroth, 1891. Thomas (1983) corrected the homonymy of Euschistus luridus Dallas, 1851, replacing the name of E. (L.) aceratos Berg, 1894. Grazia & Hildebrand (1982) transferred Berecynthus monrosi Pirán, 1963 to Euschistus; Rolston (1984), based on the illustrations of the head and spermatheca of E. monrosi provided by Grazia & Hildebrand (1982), included this species in the subgenus Lycipta. Finally, Grazia & Hildebrand (1983) described E. (Lycipta) longicornis, for a total of 12 species in the subgenus.
A new species of the genus Oxyporus Fabricius (Coleoptera: Staphylinidae: Oxyporinae) from Yunnan, China
Authors: LI GUO-FENG , ZHENG FA-KE
Published: March 2019

The genus Oxyporus Fabricius was established by Fabricius in 1775 with Staphylinus rufus Linné as the type species. Prior to this study, 114 species of the genus were known worldwide in the Palaearctic, Oriental, Nearctic and Neotropical Regions (Herman, 2001). In the subgenus Oxyporus, 37 species were hitherto known to occur in China (Bernhauer, 1933, 1938, 1943; Alekandrov, 1933, 1934; Adachi, 1939; Hayashi, 1975, 1985; Zheng, 1992, 1997, 2010; Li, 1992, 1993; Huang et al., 2005, 2006), with 30 recorded from Mainland China and 7 from Taiwan. However, only 3 species have been reported from Yunnan, China. During this study on the Oxyporus of Yunnan, we found that our specimens represent a new species. Herein, we describe Oxyporus (Oxyporus) puerius sp. nov. and provide color images of the habitus and aedeagus.

A review of the biological diversity and distribution of small mammal taxa in the terrestrial ecoregions and protected areas of Nepal
Authors: PEARCH MALCOLM J.
Published: March 2019

A review has been undertaken of the biological diversity and distribution of small mammal taxa throughout the ten terrestrial ecoregions and the sixteen principal protected areas of Nepal. One hundred and eighteen species of small mammal representing the Orders Chiroptera, Scandentia, Lagomorpha, Soricomorpha, and Rodentia are acknowledged to occur in Nepal and the distribution of each is analysed with reference to specimens listed in museum and university collections databases or detailed in published papers and reports. A further twenty-two species that are of uncertain provenance or status in Nepal are considered. One hundred and nineteen ecoregion maps document the distribution of species, while the generic richness of small mammal Orders and the distribution of Threatened and endemic taxa are mapped and discussed. All localities are listed in a gazetteer, which indicates the coordinates and elevations of 595 collection sites in Nepal. Nineteen individual recommendations are made with a view to resolving systematic irregularities and conflicts in taxonomic identifications (accession numbers of particular specimens are given where possible), to eliminating inaccuracies in type localities and species' citations, and to determining protected and other areas that would benefit from biodiversity assessments. In addition, four 25 km 2 zones are identified as important sites in which to conduct field surveys to determine the presence of Threatened, Near Threatened, and Data Deficient taxa. Mus pahari Thomas, 1916 is recorded from Nepal for the first time based on material in the collections of The Field Museum of Natural History, Chicago. The record extends the known range of the species 214 km to the west. It is considered that the classification of the Nepalese Field mouse, Apodemus gurkha, as Endangered (I.U.C.N., 2008) does not reflect the true status of the species in Nepal and an argument is propounded for the downgrading of the taxon to a lower category. The historical and political background to the study of natural history in Nepal is explained and the principal scientific investigations into the country's small mammal fauna since 1824 are summarised. It is concluded that 41% of Nepal's volant and terrestrial small mammal species are represented only by a modest number of specimens and that the small mammal fauna of 65% of the country remains unaudited.
Taxonomy and biostratigraphy of Ordovician brachiopods from northeastern Ny Friesland, Spitsbergen
Authors: HANSEN JESPER , HOLMER LARS E.
Published: March 2019

We describe Early and Middle Ordovician brachiopod faunas from northeastern Spitsbergen and discuss their biostratigraphical and palaeoecological implications. We recognise 60 species and 41 genera representing both linguliform and rhynchonelliform brachiopods. These include one new genus, the obolid Lenticulella with the type species Lenticulella amphora (Krause & Rowell, 1975), and 23 new species: Ectenoglossa? oviforma, Elliptoglossa vulgaris, Rosobolus? elongatus, Broeggeria obscura, Mirilingula? svalbardensis, Schizotreta marginalis, Conotreta convexa, Cyrtonotreta profilbekkiensis, Cyrtonotreta spinosa, Eurytreta subtriangularis, Hisingerella maniformis, Semitreta basisslettaensis, Semitreta pustulosa, Semitreta spitsbergensis, Numericoma? proclina, Eoconulus subquadratus, Dictyonites mugilis, Pelonomia sulcata, Leptella (Leptella) inequicostellata, Protoskenidioides promontorium, Anomalorthis rossi, Nothorthis subpyramidalis and Phragmorthis noda. The Ordovician succession contains both intertidal and deep-sea deposits with brachiopod faunas from nearly the whole range of environments. The Tremadocian is represented by a succession of low-diversity, rhynchonelli-6 · Zootaxa 3076 © 2011 Magnolia Pressform-dominated assemblages occupying shallow-marine environments. With the abrupt and large-scale drowning during the Floian, these faunas were replaced by a sparse slope fauna of micromorphic linguliforms. The outer shelf environments established in the latest Floian were occupied by a highly diverse brachiopod fauna dominated by micromorphic linguliform taxa. As the environment shifted toward the mid-shelf during the Darriwilian, however, the composition of the fauna changed to an Orthidiella-dominated assemblage of mostly rhynchonelliform taxa. The very late occurrence of the Orthidiella assemblage suggests that the Dapingian Orthidiella Zone found in America is probably diachronic. Although it includes many endemic species, the Middle Ordovician fauna shows a strong resemblance to the brachiopod fauna of Nevada. This study is based on approximately 16 500 brachiopod specimens obtained from both crack-out samples and acetic-acid-treated bulk samples.

A new sauropod (Macronaria, Titanosauria) from the Adamantina Formation, Bauru Group, Upper Cretaceous of Brazil and the phylogenetic relationships of Aeolosaurini
Authors: SANTUCCI RODRIGO M. , DE ARRUDA-CAMPOS ANTONIO C.
Published: March 2019

Remains of a new titanosaur, Aeolosaurus maximus sp. nov., from the Adamantina Formation (Upper Cretaceous), Bauru Group, São Paulo State of Brazil are described. The new species is represented by a single partially articulated skeleton and is characterized by having a well-developed posterior protuberance below the articular area on the anterior and middle haemal arches and a lateral bulge on the distal portion of the articular process of the mid-posterior haemal arches. It shares with other Aeolosaurus species the presence of prezygapophyses curved downward on anterior caudal vertebrae and haemal arches with double articular facets set in a concave posterodorsal surface. These two characteristics are interpreted here as synapomorphies for the genus Aeolosaurus. The new diagnosis for the genus Aeolosaurus does not support the inclusion of Gondwanatitan within Aeolosaurus as previously proposed by some authors. The phylogenetic analysis recovered the two Aeolosaurus from Argentina as sister groups with A. maximus and Gondwanatitan as progressively more basal taxa (Gondwanatitan (A. maximus (A. rionegrinus, A. colhuehuapensis))). Additionally, according to the results of the phylogenetic analysis performed in this work, the taxa Panamericansaurus, Rinconsaurus, and Maxakalisaurus are also nested within Aeolosaurini, being more basal than Aeolosaurus and Gondwanatitan. On the basis of the stratigraph-ical range of the Aeolosaurus occurrences in Argentina and the age proposals based on microfossils for the Bauru Group, it is assumed a Campanian–Maastrichtian age for the top of the Adamantina Formation for the Monte Alto region in São Paulo State and the bottom of the Marília Formation in Peirópolis, Minas Gerais State—the places where Aeolosaurus remains have been reported in Brazil.
A new species of Chaceon Manning & Holthuis, 1989, from the southwestern Atlantic, with a key to the western Atlantic species (Crustacea, Decapoda, Geryonidae)
Authors: TAVARES MARCOS , PINHEIRO ALLYSSON P.
Published: March 2019

A new species of the deep-water crab genus Chaceon Manning & Holthuis, 1989 (Geryonidae Colosi, 1923), is described from southwestern Atlantic. It is the ninth species of the genus known from the western Atlantic. It is most closely related to C. eldorado Manning & Holthuis, 1989, C. notialis Manning & Holthuis, 1989, and C. ramosae Manning, Tavares & Albuquerque, 1989, from which it can be readily differentiated in having the dactyli of P2-P5 laterally compressed, instead of being dorsoventrally depressed. A key to the western Atlantic species of Chaceon is provided.
Albula gilberti, a new species of bonefish (Albuliformes: Albulidae) from the eastern Pacific, and a description of adults of the parapatric A. esuncula
Authors: PFEILER EDWARD , VAN DER HEIDEN ALBERT M. , RUBOYIANES RYAN S. , WATTS TOM
Published: March 2019

A new species of bonefish (Albuliformes: Albulidae: Albulinae) from the eastern Pacific Ocean, Albula gilberti, is described. Previously referred to as Albula sp. A, A. gilberti is distributed throughout the Gulf of California, Mexico to the coastal waters of California, USA. Presently, it can be distinguished from its closest relative, A. esuncula (= Albula sp. C) from the tropical eastern Pacific, solely by differences in mitochondrial DNA (cytochrome b) gene sequences. No diagnostic external morphological characters have yet been found that can reliably separate the two distinct genetic lineages although some differences in placement of pelvic-fin tip relative to vent may exist. Differences detected in counts of meristic characters should be tested in larger series of specimens, especially of A. esuncula. Available evidence also suggests that A. gilberti and A. esuncula show a parapatric distribution, with an area of sympatry in the southern Gulf of California. We also provide a description of adults of A. esuncula (the original description was based solely on two larvae), review the current nomenclature of the subfamily Albulinae, and discuss the role and justification of using molecular data for diagnosing cryptic species.
Revision and phylogeny of Chelagyrtodes Szymczakowski (Coleoptera: Leiodidae: Camiarinae: Agyrtodini)
Authors: SEAGO AINSLEY E. , LESCHEN RICHARD A. B.
Published: March 2019

The formerly monotypic New Zealand leiodid genus Chelagyrtodes Szymczakowski (type species Chelagyrtodes crowsoni Szymczakowski) is revised to include five new species from the South Island: C. newtoni n. sp., C. rotundus n. sp., C. haasti n. sp., C. glacicola n. sp., and C. davidi n. sp. Four of these new species lack the unusual tibial dimorphism previously used to diagnose this genus, but can be recognized by the presence of a subapical spine cluster on the interior face of the mandible, procoxal cavities with an anterior carina or bead, and a series of minute, setiferous punctures along the lateral margins of the hypomeron. A key and phylogenetic analysis based on adult morphology is provided for the six species of Chelagyrtodes. Natural history and distribution of Chelagyrtodes are discussed in the context of phylogenetic data.
The mesostigmatid mite (Acari: Parasitiformes) fauna of Svalbard: a revised inventory of a high Arctic archipelago
Authors: ÁVILA-JIMÉNEZ MARÍA LUISA , GWIAZDOWICZ DARIUSZ J. , COULSON STEPHEN JAMES
Published: March 2019

The need for comprehensive studies of the invertebrate fauna in the high Arctic is increasingly acknowledged in order to more fully understand ecosystem functioning, resilience and to project future changes in the biodiversity and species ranges. Information on the mesostigmatid fauna in the high Arctic is scarce and scattered. Large regions of the high Arctic archipelago of Svalbard, including most of the areas in the east of the island group, have never been surveyed for the mesostigmatid fauna. Furthermore, most of the current knowledge on the mesostigmatid fauna of this important region in the European high Arctic originates from studies in the early 20 th century. Much of the associated slide material no longer exists, either being mislaid or deliberately destroyed, resulting in an ambiguous and potentially misleading mesostigmatid fauna checklist in which identifications and potential synonyms cannot be reliably assessed. Determination of fresh material sampled between 2007–2010 may be an ideal procedure to resolve the great number of uncertainties about the mesostigmatid fauna of the Svalbard archipelago. Twelve out of the 27 species recorded from the Svalbard archipelago were found in the new samples collected from a large number of localities and microhabitats. No new species were identified in the current campaign, and most of the non-observed species are considered to be past missidentifications or potential synonyms. Combining this study with recent publications provides a total mesostigmatid mite diversity for Svalbard of 22 species. This represents the most accurate checklist of the mesostigmatid mite fauna of the archipelago to date.

Re-description of Azygokeras columbiae Koeller & Littlepage, 1976 (Calanoida: Aetideidae) and musculature of the male grasping antennule
Authors: BRADFORD-GRIEVE JANET M. , BOXSHALL GEOFFREY A.
Published: March 2019

Azygokeras columbiae from Bute Inlet, British Columbia, Canada, is re-described, correcting some details and adding information not available in the original description. Azygokeras columbiae is unique amongst male Aetideidae in having the right antennule modified for grasping but without a true knee joint (geniculation) between segments XX and XXI nor a hiatus in the musculature at this joint, typical of taxa with a geniculate male antennule. Male Azygokeras have wide pivot points and arthrodial membranes between segments XXI and XXII, XXIII and XXIV and XXV and XXVI that allow greater movement in several planes than in homologous segments of Euaugaptilus and Heterorhabdus. Modifications of the terminal antennular joints allow for extensive movement in several planes associated with a series of short muscles in segments XIX to XXVI. These muscles become progressively more massive from proximal to distal on the antennule and are paired with an antagonistic muscle also increasing in mass distally.
Two new species of Helicopsyche Siebold 1856 (Insecta: Trichoptera: Helicopsychidae) from Pará State, northern Brazil

Published: March 2019

Two new species of Helicopsychidae from Pará State, Brazil, are described and illustrated: male of Helicopsyche (Feropsyche) carajas n. sp. is characterized by segment X having 8 pairs of subequal megasetae distributed in a pair of longitudinal rows; the primary branch of each gonocoxite, in lateral view, with its basal half nearly as broad as its median part and parallel-sided, its posterior apex directed slightly ventrad and slender and strongly pointed; the dorsal lobes of the endotheca posteriorly protruding, and the lateral lobes of the endotheca well developed. Helicopsyche (Feropsyche) inflata n. sp. is characterized by the hind wings each having very long fringes along the anal border; the primary branch of each gonocoxite having a pointed apex in lateral view and its basimesal lobe being triangular in lateral and ventral views and bearing eight megasetae; and the dorsal lobe of the endotheca being very well developed in lateral view.
On the Long-Wavelength Validation of the SWOT KaRIn Measurement
Authors: Wang Jinbo , Fu Lee-Lueng
Published: March 2019

The Surface Water and Ocean Topography (SWOT) mission will measure the sea surface height (SSH) using a Ka-band radar interferometer (KaRIn) over a swath off the nadir of the satellite tracks. The mission requires calibration and validation (CalVal) of the SSH wavenumber spectrum at wavelengths between 15 and 1000 km. The CalVal in the short-wavelength range (15–150 km) requires in situ observations. In the long-wavelength range (150–1000 km), the CalVal will use the onboard Jason-class nadir altimeter. Using a high-resolution global ocean simulation, this study identifies the spatial scales beyond which the nadir and off-nadir observations can be considered comparable. Our results suggest that the ocean signals at nadir can represent off-nadir ocean signals at wavelengths longer than 120 and 70 km along the midswath and the inner edge of the KaRIn grid, respectively, indicating that the nadir altimeter is able to fulfill its goal to validate the long-wavelength KaRIn measurement. The wavelength along the inner edge is limited around 70 km because the onboard nadir altimeter cannot resolve spatial scales longer than ~70 km. These wavelengths provide a reference point for the required spatial coverage of the SWOT SSH in situ CalVal.

Light (LGT) to moderate (MOD) aircraft icing (AI) is frequently reported at Cold Lake, Alberta, but forecasting AI has been a big challenge. The purpose of this study is to investigate and understand the weather conditions associated with AI based on observations in order to improve the icing forecast. To achieve this goal, Environment and Climate Change Canada in cooperation with the Department of National Defence deployed a number of ground-based instruments that include a microwave radiometer, a ceilometer, disdrometers, and conventional present weather sensors at the Cold Lake airport (CYOD). A number of pilot reports (PIREPs) of icing at Cold Lake during the 2016/17 winter period and associated observation data are examined. Most of the AI events were LGT (76%) followed by MOD (20%) and occurred during landing and takeoff at relatively warm temperatures. Two AI intensity algorithms have been tested based on an ice accumulation rate (IAR) assuming a cylindrical shape moving with airspeed υa of 60 and 89.4 m s−1, and the Canadian numerical weather prediction model forecasts. It was found that the algorithms IAR2 with υa = 89.4 m s−1 and IAR1 with υa = 60 m s−1 underestimated (overestimated) the LGT (MOD) icing events, respectively. The algorithm IAR2 with υa = 60 m s−1 appeared to be more suitable for forecasting LGT icing. Over all, the hit rate score was 0.33 for the 1200 UTC model run and 0.6 for 0000 UTC run for both algorithms, but based on the individual icing intensity scores, the IAR2 did better than IAR1 for forecasting LGT icing events.
A Cross-Cultural and Liberative Hermeneutics of Luke 10:25–37 in Asian and Asian-American Perspective: Reading One Text through the Two Lenses
Authors: Moe David Thang
Published: March 2019

The methodological reading of the Lukan parable reveals some contrasts. While Asian liberationists see the victim in the parable as the primary agent who embodies Jesus Christ, Asian theologians who focus on the intercultural hermeneutics treat the Samaritan as the primary agent who embodies Jesus Christ. This paper argues against emphasizing only one agent without embracing the other. In order to apply a fuller contextual meaning of the Lukan parable for our contemporary context, this paper argues that we should use the middle ground as the methodological tool that reads one text through the two lenses of the Samaritan and the victim. The paper first explores the Samaritan-oriented cross-cultural hermeneutics and then the victim-oriented liberative hermeneutics. Finally, the paper examines both Samaritan-oriented and victim-ordinated hermeneutics from the christological perspective and then offers five proposals for reconciling two different models for an Asian cross-cultural and liberative mission.
Managing pharmaceutical shortages: an overview and classification of policy responses in Europe and the USA
Authors: Beck Matthias , Buckley Joan , O’Reilly Seamus
Published: March 2019

This exploratory article gives a cross-sectional account of how established health-care systems have responded to the novel challenge of drug shortages. In line with previous research, our analysis confirms the existence of strong path dependence in the adoption of policy responses. This path dependence is manifested in a pronounced typology of response patterns where jurisdictional approaches to the management of drug shortages differ along two core dimensions. These are the salience attributed to the problem, and the level to which state organisations engage with the problem. These patterns are mirrored in the conceptual framing and strategic orientation of the respective drug shortage policies, with: Spanish and Irish drug shortage policies focusing on the individual product level and being largely reactive; US policies focusing on the therapeutic level, with a focus on mitigation; and German and Austrian policies seeking to address the active ingredient level, with a proactive focus on shortage prevention. Despite the importance of legacies, we find evidence of innovation and path creation particularly in relation to the US and German approaches, which we explain by the simultaneous occurrence of internal crisis and pressures from local stakeholders.

Points for practitioners

This article addresses a major challenge, drug shortages, which has emerged in recent years and could be characterised as a ‘system shock’. A typology of policies adopted based on an analysis of a range of health system responses is developed. Fundamental differences across these responses are evident, such as level of action (individual product level/therapeutic level/active ingredient level), time frame (from ad hoc/short term to long term) and strategic approach (reactive/mitigating/preventive). This analysis finds fundamentally different policies, such as delegated institutional powers and census management/network governance. The typology based on the salience attributed to the problem and the nature (proactive/reactive) of policymaking may assist stakeholders in health systems to critique their approach to this challenge and, at a more fundamental level, how the system responds to disruptive events.
Isaiah 14: The Birth of a Zombie Apocalypse?
Authors: Cook Stephen L.
Published: March 2019

Isaiah 14, a text about the infamous fall into the netherworld of a proud celestial being, has played a key role in the history of biblical understanding. In particular, the netherworld eschatology shaped Israelite end-time beliefs, or apocalyptic eschatology. In Isaiah 14, before readers’ eyes, a transcendent archetype, the ill-fated “Shining One,” materializes on earth as an historical figure, King Sargon II of Assyria. Later, the idea of an “incarnation” of the Shining One as an earthly entity evolves as a key catalyst of a radical new religious imagination. In Ezekiel 38–39, the Shining One becomes “incarnate” as Gog of Magog, a monstrous, but real, apocalyptic “zombie.” Editors first reworked Isaiah 14 as a prophecy of Babylon’s fall and later redeployed the text to depict a final, end-time reversal of Babylon’s hubris.
Isaiah’s Suffering Servant: Before and After Christianity
Authors: Brettler Marc , Levine Amy-Jill
Published: March 2019

The so-called “Suffering Servant” of Isaiah 52:15–53:12 takes on new meaning in each of his settings, from the exilic or early post-exilic community of Deutero-Isaiah, to the repurposing of this figure by the author of Daniel, mid-second century BCE during the persecutions of Jews by Antiochus IV Epiphanes, through the numerous New Testament citations of and allusions to Jesus as fulfilling Isaiah’s predictions concerning this servant, and on to several post-biblical Jewish understandings of this enigmatic figure. In showing how and why the servant receives such numerous readings, we demonstrate both how readers across the centuries and within different traditions understand Isaiah through their own circumstances, and why Jews and Christians should respect each other’s readings rather than attempt to “prove” the truth of one tradition on the basis of a specific understanding of prophecy.
Food Resources and Strategic Conflict
Authors: Koren Ore
Published: March 2019

A growing number of studies draw linkages between violent conflict and food scarcities. Yet, evidence suggests that within states, conflict revolves around food resources abundance. I develop an explanation for how the competition over food resources conditions the strategic behaviors of three actors: rebels, civilian producers who grow crops, and state forces. Using a statistical-strategic model, I validate my theory at the subnational level on new high specificity spatial data on staple crop access and productivity in Africa for the years 1998 to 2008 (and use the estimates to forecast conflict on out-of-sample data for 2009 to 2010). In line with theoretical expectations, local variations in food productivity have a positive, statistically significant, and substantive effect on the strategic behaviors of different actors. These findings suggest that the imperative for food denial as a microlevel tactic in civil war should be more seriously incorporated into the work of scholars and policy makers.
Somos pero no somos iguales/We Are But We Are Not the Same: Unpacking Latinx Indigeneity and the Implications for Urban Schools
Authors: López Josué , Irizarry Jason G.
Published: March 2019

Applying several critical race theories as analytical frameworks, the authors present and analyze counterstories of Indigenous Latinx students attending an urban high school in a “new Latinx diaspora” community, underscoring points of convergence as well as the ways their experiences were distinct from those of their Latinx peers. The findings suggest that urban school improvement efforts often ignore Latinx Indigeneity and further alienate students. As such, more complex and nuanced understandings of Latinx communities are required to improve the quality of education offered to them. The article concludes by exploring the implications of this work for educators and researchers.
Contesting imaginaries in the Australian city: Urban planning, public storytelling and the implications for climate change
Authors: Potter Emily
Published: March 2019

In Australia, environmental degradation goes hand in hand with exclusionary and mono-vocal tactics of place-making. This article argues that dominant cultural imaginaries inform material and discursive practices of place-making with significant consequence for diverse, inclusive and climate change-responsive urban environments. Urban planning in the modern global city commonly deploys imaginaries in line with neoliberal logics, and this article takes a particular interest in the impact of this on Indigenous Australians, whose original dispossession connects through to current Indigenous urban experiences of exclusion which are set to intensify in the face of increasing climate change. The article explores what urban resilience means in this context, focusing on a case study of urban development in Port Adelaide, South Australia, and broadens the question of dispossession through the forces of global capital to potentially all of humanity in the Anthropocene.
“We’re Walking Proud and Talking Loud Because We’re the New Black Joes!”: Community Leadership and Tenants Rights in Asheville’s 1968 Rent Strike
Authors: Judson Sarah
Published: March 2019

In 1967, black residents of Asheville’s public housing complexes issued a challenge to the Asheville Housing Authority. Proclaiming “we are human and we want our freedom,” tenants demanded a new relationship to the institution that governed their lives in this southern Appalachian city. The Asheville rent strike began in 1967, and with this campaign, low-income black residents punctured the oppressive political and social dynamics of the city that had rendered them invisible. With this strike, tenants articulated claims for justice based on a recognition of their dignity and a correction to unfair treatment. Despite the power of institutionalized racism and the dynamics of paternalism, black tenants flipped the script to challenge the deeply ingrained system of white paternalism that structured their daily lives. Ultimately, tenants at Hillcrest and Lee Walker Heights challenged the very nature of black leadership in Asheville, North Carolina, by taking on the city government.
Robust integral sliding mode control strategy under designed switching rules for uncertain switched linear systems via multiple Lyapunov functions
Authors: Zhang Xiaoyu
Published: March 2019

This paper puts forward a switching rule stabilization design of the robust integral sliding mode control for uncertain switched systems. A kind of common robust integral sliding mode (CRISM) is firstly designed and the system matrices of subsystems under the sliding mode comprise a robust stable matrix set. The stability of the switched system (SS) under the sliding mode is then analyzed by multiple Lyapunov functions (MLF) method. Based on the presented design of CRISM, a sliding mode controller is devised so that the sliding mode can be reached. Finally, the correctness of the proposed method is verified through results of numerical and application simulations.
The digital ephemeral turn: queer theory, privacy, and the temporality of risk
Authors: Haber Benjamin
Published: March 2019

Social media’s shift from storing media permanently by default, to supporting increasingly diverse temporalities of display and interaction has important implications for understanding the political economy of the digital. In this article, I use queer theory to complicate the normative dimensions of the privacy discourses that popularly frame digital ephemerality, suggesting instead that we understand the ephemeral as redistributing the pleasures and dangers of risk. To demonstrate, I do a close reading of the functions, design choices, and aesthetics of popular digital communication platforms, which increasingly provide the affective texture and context for everyday life. Using Snapchat and Apple’s Find My Friends and iMessage as case studies, I highlight a profitable dynamic between promiscuous exposure and monogamous retrenchment.
A study of the determinants of postgraduate students’ satisfaction of using online research databases
Authors: Islam A Y M Atiquil , Sheikh Arslan
Published: March 2019

In today’s technology-enriched environment, online research databases have become an indispensable tool in learning and research activities. Libraries worldwide have incorporated them as an integral part of their current service delivery. This study intends to determine whether the technology satisfaction model (TSM) validly measures postgraduate students’ satisfaction of using online research databases in an academic library. It further explores the relationships among antecedents within the model. To measure the components of the TSM, the stratified random sampling strategy was used to conduct a survey with 300 postgraduate students from six faculties of COMSATS University Islamabad (CUI) in Pakistan. The data were statistically analysed using the Rasch model and structural equation modelling (SEM). The results of the study illustrate direct and indirect associations among the exogenous, endogenous and mediating variables of the TSM, with the studied postgraduate students’ computer self-efficacy playing a crucial role in influencing their satisfaction. The TSM shows that 69% of the variance in the postgraduate students’ satisfaction can be explained by perceived usefulness, computer self-efficacy and perceived ease of use, which confirm that the TSM has a strong predictive power and is viable for measuring endogenous variable. The findings also make a significant contribution to the testing of databases for academics, service providers and researchers in higher education.

Published: March 2019

The purpose of the study is to test a simple approach for characterizing subjective perception in patients with choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD). This multi-center study was performed in four private ophthalmology practices including 20 patients with CNV. Subjects were presented the original image on the affected eye and afterwards modified candidate images to the contralateral eye. Then they chose one image that most closely matched the perception on the affected eye. This was repeated with three different images representing three everyday life scenes manipulated to mimic visual perception with reduced color perception (image 1), central scotomas (image 2), and blurring with four varying sizes (image 3). The frequency of response to the forced choice questionnaire experiment for each image was recorded. Our results show that images manipulated using a Gaussian blur filter, a brightness filter, and a sinusoidal distortion filter were selected by 9, 10, and 1 patients, respectively. Size of modification was not associated with visual acuity in image 1 or image 3. In image 2, however, the size of the modification was dependent on visual acuity ( p = .01). In conclusion, subjective perception in patients with AMD may significantly differ between individual patients. A better understanding of the visual disturbance will facilitate communication and involvement of patients in treatment decisions.
A systematic review and critical appraisal of quality indicators to assess optimal palliative care for older people with dementia
Authors: Amador Sarah , Sampson Elizabeth L , Goodman Claire , Robinson Louise ,   SEED Research Team
Published: March 2019

Background:

A challenge for commissioners and providers of end-of-life care in dementia is to translate recommendations for good or effective care into quality indicators that inform service development and evaluation.

Aim:

To identify and critically evaluate quality indicators for end-of-life care in dementia.

Results:

We found 8657 references, after de-duplication. In all, 19 publications describing 10 new and 3 updated sets of indicators were included in this review. Ultimately, 246 individual indicators were identified as being relevant to dementia end-of-life care and mapped against EAPC guidelines.

Conclusions:

We systematically derived and assessed a set of quality indicators using a robust framework that provides clear definitions of aspects of palliative care, which are dementia specific, and strengthens the theoretical underpinning of new complex interventions in end-of-life care in dementia.
